Kakashi Hatake

is a shinobi of Konohagakure. He received a Sharingan from his former team-mate, Obito Uchiha, when he was younger, leading him to fame as and. His prodigious talent, skill, and Sharingan prowess have made him one of the village's most capable ninja, and as such, highly recognised throughout the ninja world. He is eventually appointed the leader of Team 7, where he uses his years of experience to train his students to become skilled ninja in their own rights. At some point following the Fourth Shinobi World War, Kakashi takes up office as the.

Early life
Kakashi is the son of Sakumo Hatake, a genius renowned as "Konoha's White Fang". Little is known of his mother other than that she died at a young age. After successfully passing his entrance exam to join the Academy, he met Might Guy, who despite Kakashi belittling Guy's lack of any natural talent as Guy failed his exam, quickly came to like Kakashi. Sakumo also warned his son to not take his own training or Guy lightly, as he may one day surpass Kakashi.

Later, Sakumo fell into disgrace after choosing to save his comrades rather than complete an important mission, which caused the nation and the village to suffer a great loss. Dishonoured, Sakumo took his own life after suffering a deep depression and drop in his skills; this experience made Kakashi determined to lead his life strictly by the ninja code. Hailed as a prodigy and the best of his generation, Kakashi quickly became very popular among his peers and at age 5 he graduated from the Academy early in a single year at the top of his class. He then joined a team alongside Obito Uchiha and Rin Nohara under Minato Namikaze's command. They were given a final test to earn their full genin status; take one of two bells from Minato. As Kakashi realised that meant at least one of the three would fail, the young ninja each began to fight by themselves. Quickly being overwhelmed by the sensei's much greater skill, Kakashi came to the conclusion that only together could they even hope to defeat Minato. Kakashi managed to get Rin and Obito to work together with him, ultimately allowing Kakashi to get one of the bells. Seeing the team succeeded in the true goal of the test — team-work — Kakashi and his classmates officially became Minato's students.

During his time as Minato's student, Kakashi and his fellow students became well-acquainted with Minato's wife, Kushina Uzumaki. Growing fond of the young trio, Kushina would regularly help with their training, most noticeably bringing them homemade food for them. A year later, Kakashi became a chūnin after facing and defeating Might Guy during the third stage of the Chūnin Exams. He later became part of a one-sided rivalry with Might Guy. In the anime, with Kakashi's growing reputation as a genius, Guy approached Kakashi quickly announced his desire to challenge him. While initially Kakashi was completely indifferent to the overzealous Guy's request, Guy continued to pester Kakashi until he finally gave in to Guy's request. Despite Kakashi beating him in every challenge, including various forms of marksmanship, taijutsu combat, and even physical comparison, Guy became only more determined to defeat Kakashi. Seemingly warming up to Guy, he continued to accept Guy's various challenges (including eating contests and Rock, Paper, Scissors), ultimately giving Kakashi a record of 49 wins and 50 losses.

Third Shinobi World War
Soon after becoming a jōnin, Kakashi was assigned to lead his team-mates Obito and Rin on a mission that would benefit Konoha in the ongoing Third Shinobi World War. They were to destroy Kannabi Bridge, which was being used by Iwagakure forces to move into Kusagakure. This would also be Konoha's first huge offensive move in the war. On their way to the bridge, Rin was kidnapped by two Iwagakure ninja named Kakkō and Taiseki. Obito immediately suggested that they rescue her, but Kakashi disagreed on the basis that they needed to complete their mission, opting not to make the same mistake his father did in his mission.

Obito would not hear of it and stubbornly left to save Rin, but not before mentioning that he believed Kakashi's father, the White Fang, was a true hero. Shortly after parting ways, Kakashi reflected on Obito's words and Rin's prior kindness. He realised that his father was not wrong after all, which prompted him to join Obito in the rescue effort. Kakashi arrived in time to save Obito from Taiseki, using his father's blade to combat him. Despite the two-to-one disadvantage, the more experienced Taiseki was able to attack and injure Kakashi, who took the blow that was intended for Obito, giving him a permanent scar while also ruining Kakashi's left eye to such an extent that Kakashi was left with only one good eye for the duration of the mission.

Obito's will to protect his comrades caused his Sharingan to awaken which in turn helped kill Taiseki. After finding Rin and defeating Kakkō with Obito's help, Kakashi freed Rin from the genjutsu before their opponent attempted to trap them in a cave-in. While trying to escape, Kakashi was hit by a rock, which he didn't notice because of his bandaged eye, causing him to fall. Obito pushed Kakashi out of the path of a huge falling boulder, getting himself crushed instead. This resulted in the right side of Obito's body being crushed beyond repair.

Knowing he was dying, Obito requested his Sharingan be a belated present to Kakashi and instructed Rin to implant his left Sharingan into Kakashi's lost eye. Rin complied, and as soon as the surgery was completed Kakashi used his new Sharingan to perfect his Chidori and kill Kakkō. He then returned to Obito to see if there was anything he could do for him, but alongside Rin was forced to leave him. With the help of Minato, they ultimately completed their mission, allowing them to mourn Obito's apparent death.

At some point during this time, Kakashi signed a summoning contract with the ninken. Later, in the anime, Kakashi and Rin's team was given Might Guy as a replacement. It was during this mission that Kakashi and Guy found true trust and team-work with each other, and where Kakashi famously split a lightning bolt with his Chidori, giving birth to its new name Lightning Cutter. Later, during another mission, Kakashi met a young girl named Hanare of the Jōmae Village who was lost. He taught her about how the clouds can help her find her way and find her teacher.

Sometime after the events at Kannabi Bridge, Rin was taken captive by Kirigakure. With the help of his nin-ken pack, Kakashi was able to track her down. Kakashi was able to rescue her, but not before she was forcibly made the jinchūriki of the Three-Tails. While returning to the village, they were ambushed by jōnin and Anbu-level Kiri shinobi. Rin, who knew about Kirigakure's plan to unleash the beast on Konoha, begged Kakashi to kill her. After he refused, Rin waited for Kakashi to attack, and intentionally got in Kakashi's path, culminating in a tearful Kakashi piercing through Rin's chest with his Lightning Cutter, leaving the Kiri-nin stunned and Kakashi himself devastated. Shortly afterwards, Kakashi and Obito — still alive and witnessing it from behind the scenes — developed their fully-matured Sharingan and subsequently awakened the Mangekyō Sharingan at precisely the same time.

Exhausted and overwhelmed with sorrow and grief at his part in Rin's death, Kakashi lost consciousness and passed out while Obito, whose own rage and grief manifested itself in his new wood based abilities, went on a rampage and brutally killed all the Kirigakure ninja. Though Kakashi technically was the one who killed Rin, Obito left him alive, and he was later found by Konoha reinforcements. In the anime, despite his growing career, Kakashi was still haunted by having killed Rin with his own hand, having nightmares and visions that visibly shook him. Since then, Kakashi avoided his fellow classmates. When Minato was elected Hokage sometime later, feeling that Kakashi needed a new direction in life following the loss of Rin, he assigned Kakashi to join the Anbu despite his student's young age under his direct command.

Post-War
After the conclusion of the war, Kakashi worked hard at his new position and quickly built a famous reputation during his first year in Anbu. However, much of it came from his cold-hearted and ruthless approach in battle, stemming from his bitterness at losing Rin. Likewise, many people had a misconception that Kakashi killed Rin purposely for the sake of preventing her from leaking information, earning him the nickname "Friend Killer Kakashi". Eventually, he was promoted again to Anbu captain and leader of Team Ro that responded directly to the Hokage. Later, Kakashi learned from Minato that Kushina was pregnant and was entrusted to protect her during her jinchūriki-induced ten-month pregnancy. Kakashi followed this order very faithfully and never let Kushina out of his sight, constantly monitoring her from the shadows, even when she was with Minato, making his presence meaningless. Kakashi would often visit Rin and Obito's respective graves in the Konoha Cemetery and the Memorial Stone, cleaning their tombstones and bringing them flowers. On one such occasion, he visited Rin's grave and told her that their sensei's child would be born soon and left to go to the stone, unaware that Tobi was watching him and overheard Kakashi reveal where Kushina would birth her child. On the night of Kushina's due-date, Kakashi felt an ominous presence in the air. Soon after, the Nine-Tails appeared. During the Nine-Tails' attack on Konoha, Kakashi and the rest of his peers were barred from participating in defending the village by Shinku Yūhi and other senior shinobi for their own safety as the younger generation.

While Kushina and Minato managed to seal away the Nine-Tails, they and many others perished from the attack. After Hiruzen was chosen to resume his duties as Hokage, Danzō Shimura approached a grieving Kakashi. He pointed out that Kakashi was unable to aid his late sensei and possibly save him because of Hiruzen's orders. Convinced in Danzō's reasoning, Kakashi grew to resent Hiruzen and felt that he was not fit to lead the village, deciding to take Danzō's offer to join the Anbu Root division and spy on Hiruzen for Danzō. During a delivery, Kakashi was attacked by a boy codenamed "Kinoe" who could use Hashirama's Wood Release. Danzō broke up the fight, revealing to both they were under his orders. Knowing that only the First Hokage was supposed to have the Wood Release, Kakashi sneaked into the Hokage Residence to investigate. Soon after, Kakashi was approached by Hiruzen. Despite the intrusion, the Third Hokage presented Kakashi with the records of the Wood Release, explaining that in the past it was attempted to recreate the First Hokage's Wood Release, but consistently ended with failure and death of the subjects, ultimately ceasing the research and deeming it forbidden.

Hiruzen also explained that recently, several people, from children to adult, have gone missing with suspicion that someone was resuming the research. He reluctantly expressed that any replication of the Wood Release could have saved the village from the Nine-Tails' attack. Realising that Hiruzen truly cared for the well-being of the village and that Danzō knowingly kept a valuable asset in the Wood Release child a secret, Kakashi told Hiruzen of Danzō's plan to assassinate the Third before he could resume power. The following day Kakashi went in Hiruzen's place to lure out the assailants, one of which was Kinoe. Kakashi easily defeated him, but chose to spare him, knowing he would be valuable ally in the future. Later that night, Kakashi requested to resign from Anbu, feeling unworthy from have betrayed the Third's trust even once. Hiruzen however insisted that Kakashi's assistance was needed during these time, having said so to Minato himself. Ultimately, Kakashi agreed to stay working as Hiruzen's right-hand man and told him of Kinoe.

Later, Orochimaru of the Sannin was discovered to be responsible for the disappearance of Konoha citizens and was attempting to escape the country. After Orochimaru escaped the Third Hokage and company's ambush, Kakashi intercepted him as he left his hideout, only to be swiftly outmanoeuvred by the older ninja. Taking advantage of Orochimaru's love of snakes, Kakashi and Hiruzen used a backup plan to let a snake get close enough to Orochimaru and detonate an explosive tag inside its mouth, severely injuring the Sannin. Despite the handicap, the malice in Orochimaru's eyes alone was still enough to freeze Kakashi in his tracks, allowing Orochimaru to escape. After regaining his composure, determined to not let Orochimaru leave the country, Kakashi summoned his ninken to find the missing-nin. Kakashi soon found an underground cave. Once inside, he was attacked by the Iburi clan, loyal servants to Orochimaru. Using their unique ability to become smoke, the clan quickly subdued Kakashi. Kinoe, who was a welcomed guest, convinced them to let Kakashi live so he could interrogate him.

While talking alone, Kinoe revealed that like the Third Hokage, Danzō too viewed Orochimaru as too dangerous to let leave the country. The Iburi leader Gotta, heard this while spying and quickly sought to kill the two Konoha-nin. However, one of the clan members, Yukimi, chose to save Kinoe, and by extension Kakashi, as she was convinced Kinoe was her brother Tenzō. After Yukimi left Kakashi behind to leave with Kinoe, Kakashi found his way outside, but was quickly attacked by Gotta. Ultimately, Gotta's smoke form became his undoing because of his weakness to wind. As he died, he begged Kakashi to get back Yukimi, who was very valuable to Orochimaru. Kakashi soon found Yukimi and Kinoe, telling Kinoe that they needed her to capture Orochimaru. Having grown close to her, Kinoe instead ran away with her. Quickly catching up to them, he explained that Yukimi's blood could bestow Orochimaru with the Iburi clan's smoke transformation, meaning Orochimaru would go to the cave. Overhearing that, Yukimi slipped away and returned to the cave. Recognising that Kinoe cared for Yukimi like Kakashi did for Rin, the two agreed to work together to save her. Upon the duo returning the the cave, Orochimaru killed all the Iburi in his search for Yukimi, finally capturing her. As the cave began to collapse Orochimaru decided to escape, leaving Yukimi as her body then began to destabilise, but the spirits of the Iburi used their power along with Kinoe's Wood Release to re-stabilise Yukimi, finally allowing her to enter the world without fear of the wind. Kakashi decided to leave and not report anything about the Iburi or Root's involvement.

Over the years, Kakashi became well-known amongst all the Five Great Shinobi Countries for the extensive use of his Sharingan, gaining him a reputation as "the man who has copied over a thousand techniques", hence his nickname. Three years after Orochimaru's defection from Konoha, one of his secret labs was discovered. Knowing the potential traps inside, Hiruzen sent Kakashi to investigate. There, he met up with Kinoe again, who was on a mission of his own. Inside the lab, as Kakashi found to his horror some kind of snake creature, Kinoe attacked Kakashi, as his mission was to retrieve Kakashi's Sharingan for Danzō. As Kakashi tried to reason with Kinoe, saying that missions should never overshadow loyalty to a friend, Kinoe retorted this, noting that Kakashi killed Rin. Enraged by that remark, Kakashi quickly overpowered Kinoe. Still viewing Kinoe as a friend and ally to the village, Kakashi chose to bring Kinoe to the Third Hokage. Before he could, one of Orochimaru's snake experiments escaped its test tube and attacked the duo. As Kinoe was taken captive, Kakashi managed to slay the creature. While saving Kinoe, the creature's corpse began emitting a poisonous vapour which quickly infected Kakashi. Kinoe got Kakashi out safely and, having accepting Kakashi's words, Kinoe gave Kakashi an antidote and chose to abandoned his mission. After Kakashi regained consciousness, reading Kinoe's letter, he realised Danzō would not tolerate insubordination, Kakashi quickly went to the Third Hokage for help. Giving Kakashi a summon request to be delivered to Danzō, he went to Root headquarters, where the guards claimed Danzō was somewhere else. Not believing them, Kakashi used his Sharingan to learn Kinoe was taken to be implanted with a cursed seal. Kakashi quickly found Kinoe and freed him, only to be surrounded by Danzō and his men. Before Danzō could execute Kakashi on the grounds of trespassing, Hiruzen arrived to vouch for Kakashi coming. Sparing Kakashi of any punishment, Hiruzen turned his attention to Kinoe and convinced Danzō to turn him over to his direct command. Later, Kakashi welcomed Kinoe to his squad, insisting that Kinoe now go by his chosen name of "Tenzō", which he happily agreed to.

Three years later, Itachi Uchiha, another prodigy even younger than Kakashi was at the the time, joined Anbu as part of Kakashi's team. While Kakashi's men doubted letting such a young child join, Kakashi noted Itachi's exceptional capabilities. Later, Kakashi and Itachi were assigned to a mission of observing a meeting between Konoha and the Land of Woods. They were tasked to kill the Land of Woods' Prajñā Group if they betrayed the Konoha-nin after an exchange of scrolls was made. When the Wood-nin revealed their treachery, Kakashi and Itachi swiftly defeated them. Afterwards, Kakashi congratulated Itachi for his excellent performance. Also watching Itachi's merciless approach made Kakashi realise the dark side of being in Anbu, telling the young Uchiha the importance of friends. Two years later, Kakashi and Itachi were assigned to spy on the Uchiha clan under the continued suspicion that they played a part in the Nine-Tails' attack years ago. Later, during another Anbu mission, Itachi approached his senior, asking his opinion on honouring a dead friend's request, to which Kakashi firmly say one should always do so.

Later, when Itachi was promoted to Anbu captain himself, the youngest in history, Kakashi openly congratulated his former subordinate. He was quickly met up with by Yūgao Uzuki. As Kakashi was already her senior and mentor, Yūgao was thrilled to announce that she was the new replacement for Team Ro and working with Kakashi. Afterwards, Kakashi was called upon the Third Hokage to look into the repeated infiltration of Konoha by an unknown individual without setting off the village barrier warning. Kakashi was given the locations of key points that erected the barrier in hopes of finding any weaknesses or changes. While sent as a non-Anbu, once looking within the Uchiha district, Kakashi quickly realised the disdain the entire district had for him, a non-Uchiha. Later, Team Ro was mobilised to the Uchiha District, under orders to pacify the Uchiha before civil war could happen. When Kakashi was shocked to discover the complete annihilation of the proud clan, save for its youngest member, Sasuke. Danzō then appeared, explaining that Itachi had long since begun to despise his clan, even taking the late Shisui's Sharingan in a pursuit of greater power, and ultimately decided to kill the clan off. Horrified to hear what his friend did, Kakashi began to lament at his inability to help Itachi avoid such an outcome.

Later, feeling similar regret to Itachi's recent actions, feeling it was a mistake to put a kind heart like Itachi's in Anbu, a remorseful Hiruzen called upon Kakashi. While applauding Kakashi for his superb work in Anbu over the past ten years, Hiruzen decided to relieve Kakashi of any further service, fearing that Kakashi's heart would only darken from the experience, and was instead appointed a jōnin sensei. Kakashi would go on to test many genin but would never pass any of them due to their inability to live up to his expectations of working as a team. In the anime, this stemmed from the shame of him never having shown true team-work with his own rookie team. He would use various methods to test true loyalty and cooperation between his students, constantly showing no signs of doing so. When Kakashi began to doubt his methods as Minato himself overlooked Kakashi's original lack of team-work, several of Kakashi's former potential students began to prosper from his actions, showing true loyalty to their allies as Kakashi originally intended, thanking Kakashi for his help. Kakashi was happy his students learned to value team-work, reaffirming his faith in his methods. He once had a mission where Iruka, his team-mate at the time, was injured and decided to become an instructor at the Academy. When Iruka was having doubts about being the home room teacher of Naruto Uzumaki, Kakashi served to remind him of his real reasons for wanting the post in the first place.

Personality
Since his early childhood, Kakashi was very independent and self-confident, at times even appearing arrogant and condescending. Despite that, Kakashi was very perceptive and intuitive, quickly realising the situation for what it was. From this, he was well-aware of his limits and is willing to work with others to accomplish his tasks. After his father's death, Kakashi became more stern and serious, following all the rules to the letter and chastising any who disobeyed them, like his team-mate Obito. He was also very aloof and apathetic to others especially Obito, who was always late for their missions and would come in tow with a grand excuse. This caused Obito to resent Kakashi; the dynamics between the two would soon change after Obito was mortally wounded during the Third Shinobi World War, with Kakashi and Obito becoming closer friends after Rin was abducted.

Obito's supposed death had a huge impact on Kakashi's personality, adopting many of his friend's cheerful mannerisms such as having greater concern for his team-mates and students over the successful completion of a mission, as well as believing that team-work is essential to overall success as a team. He has also developed a somewhat carefree personality and is regularly late for appointments, making obvious excuses just like Obito before him. This is often because he loses track of time during his frequent visits to the memorial stone where Obito's name is engraved. However, Kakashi is still just as apathetic as he was during his youth, often speaking bluntly about sensitive topics.

In the anime, after the death of Rin by his own hands, Kakashi developed post-traumatic stress disorder, having numerous nightmares of Rin's death and waking up to wash the hand that killed her. Kakashi also occasionally ignored his fellow classmates, especially Guy, whenever he passed by them. Thinking it would ease his pain, Minato convinced Kakashi to join the Anbu. During his time in the Anbu however, Kakashi gained a reputation for his cold-bloodedness, mercilessly killing a shinobi impersonating an Iwa shinobi instead of sparing him for interrogation. His bitterness at losing Rin also made Kakashi easier to manipulate by Danzō into betraying the Third Hokage, claiming he was responsible for the deaths of his team.

Though his childhood was riddled with numerous despairs that took those dear away from him, Kakashi is on the best terms with his childhood friends: Guy, Asuma, and Kurenai, his students and generally with everyone in Konoha to a lesser extent. His devotion to his friends and the rest of Konoha were the motivation to perfect both the Chidori, and its enhanced version Lightning Cutter. After the formation of Team 7, Kakashi begins taking a special interest in his students' development, especially in the case of Naruto and Sasuke, whose rivalry reminded him of his relation to Obito. Like Hiruzen, Kakashi loved all of his students deeply, turning down a mission in order to stop Naruto and Sasuke from killing each other. Despite Sasuke allying with Orochimaru, Kakashi shared Naruto's hope that they could save him. However, Kakashi became originally distraught about having to kill Sasuke after he became an enemy of Konoha, especially since he felt that it was his shortcomings as their teacher, including including how he once made an empty promise to Sakura that things would be all right for Team 7 despite not even being sure of it himself, that attributed to this and Naruto and Sakura's temporary falling out earlier, but then furiously discarded his hesitation after Sasuke attempted to kill Sakura without a second thought. However, after Naruto finally managed to make Sasuke let go of his anger and darkness, Kakashi could not help but smile while watching as his students laughing together again after so many years of trials and tribulations. He even used his pull as the new Sixth Hokage to pardon Sasuke of his crimes in his service to ending the war.

Kakashi has a rather solitary, and matter-of-fact attitude. He often displays a bored and unenthusiastic expression. His calm and detached demeanour has been called "cool, hip, and trendy" many times by Might Guy. Despite his increasingly growing reputation and prowess as a ninja, Kakashi has shown no signs of arrogance, and is rather modest about his abilities, as shown when he readily praises others for leaps in their combat abilities and stating on more than one occasion that Naruto has surpassed him in power. When suggested by many for him to become Hokage, Kakashi openly admitted to feeling unworthy, but would accept the post for the sake of the village's well-being. His naturally calm attitude is used to his advantage in battle, as it becomes easier for him to maintain his composure and stay focused on the situation at hand, and notice everything around him. Even in near-death situations, Kakashi is able to stay collected and resourceful. As a result, he can quickly adjust to any situation to make keen and thought-out decisions, allowing him to stay steps ahead of his opponents.

Despite his usually stoic demeanour, Kakashi does have an emotional side, as he noted during the Fourth Shinobi World War that it took a lot to get him worked up, but when he did, he would go on a merciless rampage against the enemy. True to his teachings to his students, Kakashi as an adult is fiercely loyal to his allies and quick to acknowledge a situation requiring assistance. He is likewise open to people changing, seen from his willingness to work alongside a reformed Kurama despite it killing Kakashi's sensei, Minato. His loyalty, however, also works to his disadvantage. Horrified at learning that Tobi was actually his thought to be deceased comrade Obito, Kakashi became momentarily depressed and no longer reacted to what was occurring on the battlefield. After getting over the initial shock, while willing to fight Obito, Kakashi could only bring himself to the extent of protecting his allies, too hesitant to perform lethal attacks, even when gaining the upper hand in the fight. Obito noted this came from Kakashi's regret at failing Obito and continued hope to reason with him. As the fight dragged on however, Kakashi came to the realisation that in order to protect Naruto and preserve the memories of how Obito was, he would have to kill the current one.

Kakashi has an ongoing, albeit one-sided, somewhat childish rivalry with Guy. In trying to prove himself superior to Kakashi, Guy regularly challenges him to competitions of questionable value. Kakashi, on the other hand, shows very little interest in their competitions, which only further inspires Guy to defeat Kakashi and his "coolness". However, Kakashi did show disappointment when he learned that Guy taught Lee how to open the dangerous Eight Gates, which turned to sympathy when Guy shows how much his student meant to him. Nevertheless, both men are great friends and also have the utmost faith in each other seen during the Fourth Shinobi World War when they entrusted the protection of their blind spots to each other. This was also expanded on in the anime, where Kakashi told Tsunade that he would need a second-in-command during the war and wanted Guy to serve that purpose.

Kakashi is an avid fan of the Icha Icha series of novels by Jiraiya, revealing a perverted side. He is typically seen reading one of the books in his spare time, making it the only one of his reportedly several hobbies that is ever seen in the series. He even went and read it during his first bell test with the newly formed Team 7 as he deemed Naruto too weak of a threat. However, during the second bell test with Naruto and Sakura, Kakashi lost to his students when his love for the book series was used against him and he was forced into covering his ears and closing his eyes to avoid being told the ending of the latest instalment he had yet to read at the time. Despite his fondness for the books, Kakashi is uncomfortable about reading passages to others (even around his ninken), presumably embarrassed by the adult content, as noted when they were decoding Jiraiya's last message.

Kakashi also appears to carry about a pair of bells attached to a red thread. These same bells are used in his genin survival test when testing Team 7. He's often seen with them and while remembering Obito's words and lessons taught by his sensei.

Even after losing his Sharingan and having his left eye restored, Kakashi still maintained the habit of covering it from time to time.

Appearance
Kakashi is a fit and relatively tall shinobi, with spiky silver hair, and has dark-coloured eyes. Since his first jōnin mission, he obtained a small vertical scar running over his left eye (which was soon replaced by a Sharingan). While yet to be revealed why, since early childhood, Kakashi has worn a mask over the lower-half of his face. In the few instances that Kakashi is seen without his mask, it has been seen that he has a narrow jaw-line; in these instances the parts of his face normally covered by his mask are obstructed from view. In the anime, it is strongly suggested that he is in fact very handsome, as seen from Teuchi and Ayame's reaction to seeing his face. He was once mistaken by Chiyo for his father Sakumo Hatake, whom he greatly resembles, despite most of his face being obscured. Kakashi's personality is further emphasised by his generally lazy expression, aloof manner, relaxed voice, and minimalist attitude. In serious situations, however, he is shown to have a very stern and intense look.

As a child, Kakashi wore a simple black outfit. He also wore a scarf with a simple design running along its length to the entrance ceremony, which he would later swap out for a plain, green one. As a genin, he wore another simple black outfit along with an open-front apron around his waist and fish-net armour around his ankles. During his early missions as a jōnin, he wore a black T-shirt with white stripes in the middle of the sleeves. On his arms he wears black sleeves with metal arm protectors over them. He also has leather straps around his back and chest, and his family's White Light Chakra Sabre is kept in a small holder out in the back. He also wore pants similar to the ones he wears today. He appears to wear the same type of outfit as a child (as seen in a flashback). However, in another flashback he is shown wearing a sleeveless black shirt similar to one he sometimes wears as an adult. This type of shirt is presumably for casual wear. After receiving his Sharingan, Kakashi would tilt his forehead protector to the left, covering up the eye until he was ready to use it. Later as a teenager, he wore a black body suit with a variation of the wartime variant of Konoha's flack jacket prior to the Nine-Tails' Attack on Konoha.

While an Anbu member, Kakashi wore the standard uniform which consisted of a simple blue suit with a grey flack jacket, strapped up sandals, and arm guards. Along with this he wore plated gloves that went all the way up to his arms with a bandage wrapped around the right one. Along with this he carried a sword strapped to his back and his mask was fashioned to resemble a dog's face with red and black markings around the eyes, sides and mouth. In addition, Kakashi has the Anbu tattoo on his left shoulder, and didn't wear a forehead protector during his time at Anbu. In the anime, after becoming an Anbu captain, he also occasionally wore a brown cloak over his uniform.

While working as part of the regular forces, Kakashi donned the standard jōnin attire: a Konoha flack jacket, dark blue pants and a long-sleeve shirt with the addition of wearing shorter, fingerless gloves with metal plates on the backhand. He also wears a chain necklace. During the Fourth Shinobi World War, Kakashi's Sharingan was stolen by Madara Uchiha. Shortly afterwards, Naruto, using the power he obtained from Hagoromo Ōtsutsuki, restored Kakashi's original left eye.

Two years after the Fourth Shinobi World War, Kakashi, now the Hokage, has barely changed in appearance. When on duty, he wears his forehead protector levelled again, exposing both eyes. His boots now reach his calves and his flack jacket is changed to a simple chest-guard that has clipped-on shoulder pads with high collars and a dark blue strap across his waist with rectangular pouch behind the left of his back. On the back of the flack jacket, Kakashi has the kanji 六火 (Literally meaning Six Fire) written vertically. In addition, he wears a red armband with the Uzumaki crest over his left bicep. At times, Kakashi would also wear the official Hokage uniform. This outfit consists of the traditional headpiece and haori, along with a red, full-length kimono that is tied using a white sash and a white mantle around his shoulders. On the backside of his robe, Kakashi has the kanji for written vertically.

Some time after stepping down as Hokage, Kakashi wears a green-coloured variant of his previous chest guard, and has seemingly stopped wearing a headband. He gains slight wrinkles under his eyes, further increasing his resemblance to his father.

Abilities
Kakashi was noted by Tsunade and Jiraiya to easily be one of Konoha's strongest ninja. He is hailed as a natural genius ever since early childhood, evidenced by his meteoric rise through the ninja ranks and ability to fight back an entire squad of elite ninja. As an adult, he is frequently given responsibility for important tasks, such as keeping the Nine-Tails' seal in Naruto intact. His various accomplishments and reputation have made him well-known throughout the ninja world, and most opponents of any level grow afraid or excited at the idea of fighting him. Even S-rank shinobi such as Itachi recognised Kakashi as a dangerous opponent to fight alone, and Nagato viewed Kakashi as a major threat that could disrupt his plans if left unchecked. During the Fourth Shinobi World War, Kakashi defeated several famous reincarnated shinobi, pressured multiple "Version 2" state jinchūriki, and fought evenly against the adult Obito, who gained comparable prowess to Madara Uchiha. After obtaining both Sharingan and the Six Paths Power from Obito, his abilities allowed him to threaten and even harm Kaguya Ōtsutsuki, the progenitor of chakra. Despite losing his Sharingan after the war, Kakashi's still formidable prowess enabled him to become the Sixth Hokage, a position he has been considered for years by many prominent people to hold.

Taijutsu
Kakashi is very adept in taijutsu. In the anime, as a child, he could hold his own against his sensei, Minato, in the bell test, even managing to touch a bell. As an adult, his skills improved considerably, being able to easily defeat hundreds of enemies using well-coordinated attack patterns. Kakashi can also fight on par with Might Guy, a taijutsu master, ever since childhood. Likewise, from his various challenges against with Guy, Kakashi has copied and developed great skill in his friend's Strong Fist-style and several of its techniques, enough to train others in its usage. He can also open at least one of the Eight Gates, a feat that very few shinobi can achieve and, in the anime, utilise advanced techniques derived from it while showing no signs of fatigue afterwards. His raw strength is noticeably high, able to clash with a physically strong opponent like Zabuza Momochi, who was wielding the rather heavy Kubikiribōchō, simultaneously throw Naruto and Sasuke a large distance, snap Nagato's chakra receiver with his bare hand, and easily wield the Kubikiribōchō himself with a single hand for extended periods of time. He's shown a rather impressive level of durability and endurance, able to survive Nagato's building busting Shinra Tensei from up close with minimum damage and continue fighting afterwards.

Kakashi has impressive speed, able to intercept an opponent faster than unfocused eyes could follow even from a distance. His speed allows him to effectively catch his opponents off-guard to quickly strike them down and easily evade attacks. Kakashi can even silently sneak-up on highly experienced assassins, making him prime to strike. His speed increased considerably in Part II, being able to match Itachi, whom he had trouble keeping up with before the time-skip. During the Fourth Shinobi World War, he could keep up with a Version 2 jinchūriki despite its enhanced and multiple fields of vision, and keep pace with Guy using six of the Eight Gates. Kakashi was even able to blitz and nearly sever Kaguya's arm in one move, despite having her multiple dōjutsu active. Likewise, his hand seal prowess is very great, able to perform them at highly difficult speeds to follow. Kakashi has also shown remarkable reflexes, able to instantly react and effectively manoeuvre out of surreal danger.

Genjutsu
While used less often, Kakashi has shown proficient skill in genjutsu, which he can use as a set-up for stronger attacks. His skill in its usage is able to easily deceive most opponents with well-timed diversions, giving them little chance to counter. During the bell test for Team 7, Kakashi was able to use low-level techniques to easily subdue a keen-minded and natural genjutsu-type like Sakura. Against most high-level techniques, he has advanced knowledge of their working, and is able to dispel genjutsu as well. He was also able to battle the adult Obito, a potent genjutsu user comparable to Shisui Uchiha, to a standstill.

Ninjutsu
Kakashi primarily relies on his mastery of ninjutsu, possessing both great skill and otherwise knowledge of which he has gained a vast arsenal due in part to his Sharingan; being noted to have copied over a thousand techniques, the number has continually been growing through his many battles. With this arsenal, he can attack or defend in numerous manners. He can immediately discern what type of technique he has encountered and the nature behind it. While a student under Minato, Kakashi learned among other things how to use the Rasengan. He also demonstrated noticeable skill since childhood in advanced techniques like the Shadow Clone Technique.

Nature Transformation
Kakashi is a master of several basic nature transformations, along with Yin Release and Yang Release. He has a natural affinity for Lightning Release, which he has used extensively and mastered to the point that he has become synonymous with the element. After learning the Rasengan, which was intended to have its user's nature transformation added, Kakashi failed to combine his Lightning Release chakra with it. However, he used the same theoretical principle to create the Chidori, which he later refined into the far stronger Lightning Cutter. He can work with a shadow clone to create a lightning chain that increases his attack range and strength to even cut through a "Version 2" jinchūriki's chakra arms. He can also create a lightning-infused clone, and hound.

His prowess with Water Release can match specialists like Zabuza and he can perform these techniques without a nearby water source. In the anime, he could likewise produce a vision impairing thick mist, able to negate most genjutsu that he could effectively manoeuvre himself through. His Earth Release prowess lets him move fast and unnoticed underground or quickly produce large and intricate earthen walls. He showed similar proficiency to this element while still a child. In the anime, he has also shown considerable skill in Fire Release, able to produce a massive fireball able to cause much damage to the area. In addition, he is knowledgeable enough to train others in Wind Release.

Utilising the Six Paths chakra given to him by Obito, Kakashi is able to enhance his Lighting Cutter, producing a black and more powerful variation of it strong enough to damage the likes of Kaguya. Using the power of both Obito's Mangekyō Sharingan, Kakashi can perform Kamui in unison with this new Lightning Cutter, greatly reducing the resistance to his attack.

Bukijutsu
Kakashi is a highly-skilled user in a large variety of weapons such as bows and arrows, kusarigama, chains, wire strings and others. Since early childhood, Kakashi had highly proficient skill in kenjutsu, able to wield his father's signature tantō effectively enough to be mistaken for Sakumo. Due to his Anbu background, Kakashi's sword skill was especially improved and became very adaptable, able to effectively use the Kubikiribōchō, a blade of unique shape with noticeable size and weight, to defeat kenjutsu specialists like the Seven Mist Swordsmen. He can also enhance his physical tools by channelling lightning-nature chakra through them, gaining enough power to pierce clean through large rocks. He also has considerable skill in shurikenjutsu able to pin down an opponent with a quick barrage of kunai and even effectively launch kunai with a well-placed kick. Likewise at close-range, he has great dexterity in simultaneously wielding one in each hand. Against skilled melee-fighters such as Zabuza and Hidan armed with their respective unique weapons, Kakashi could fend each off with a single kunai. Kakashi can also apply this skill to his Complete Body — Susanoo, able to quickly launch a large barrage of shuriken with very precise aim.

Summoning Technique
Kakashi is able to summon a pack of ninja hounds of various breeds. Much like his combat skills, Kakashi's use of these summons is highly versatile, ranging from attacking and restraining his opponents. He can combine his Summoning Technique and his Earth Release skills to have his hounds burrow and erupt from the ground in order to help subdue his enemies. Aside from offensive purposes, Kakashi's pack is also highly skilled in tracking down targets, and delivering messages.

Sharingan
Kakashi's most distinguishing ability was his Sharingan, which was given to him by Obito Uchiha to replace his left eye. Kakashi has gained much fame for his usage of its various abilities, earning him worldwide recogniton as. He was very skilled in its usage, having been selected to train both Sasuke and Itachi to help develop their own dōjutsu, and likewise was noted by various prominent Uchiha to have greater proficiency than most true Sharingan wielders. Kakashi has been noted to have copied over one thousand jutsu with his Sharingan, also becoming known as the. Kakashi was able to perform debilitating genjutsu with simple eye contact and was able to battle back an adult Obito through a repeated stalemate of illusionary fighting until he himself asked that they stop this routine. The Sharingan also granted Kakashi advanced analysis of the environment, and predicting his opponent's next move. With his heightened visual perception to his surroundings, Kakashi was able to perfect his Chidori and Lightning Cutter with no fear of counterattacks.

When he first recieved it, Kakashi's Sharingan was not yet fully matured, only having two tomoe. Later, the traumatic loss of his dear friend Rin Nohara at his own hand caused Kakashi's Sharingan to fully mature. Because he is not an Uchiha, Kakashi was unable to deactivate this dōjutsu. This forced him keep it covered when not needed as it also consumed a much greater reserves of chakra than an Uchiha, which left him bedridden if overused. Because of this, Kakashi only relied on it when absolute necessary. In Part I, he could only handle using it for a short while in battle before suffering somewhat crippling effects and severe fatigue. In Part II, his efficiency with maintaining it greatly increased, able to use it for seemingly an entire day without any adverse effects.

Later, during Fourth Shinobi World War, Madara stole Kakashi's Sharingan in order to gain access to the other dimension. After Obito died with both his original eyes, he used Kamui to briefly return to the living world. Entering Kakashi's subconscious, he transferred his chakra and both Sharingan to Kakashi, whose left eye had been restored by Naruto. Manifesting both Sharingan, Kakashi was able to use both eyes to their full potential, with the Six Paths Chakra Obito transferred to Kakashi further increasing their power. After Obito departed for the Pure Land, his Sharingan faded from Kakashi's eyes.

Mangekyō Sharingan
Originally, Kakashi awakened the Mangekyō Sharingan in his left eye after unintentionally killing Rin, though he seemed unaware of its awakening until years later. Its design is three stretched triangles evenly spaced around the pupil that each curve at the top around the eye to form a circle, making it similar to a pinwheel. After Madara stole Kakashi's Sharingan, Obito later transferred his full dōjutsu's power into Kakashi, and with it the ability to manifest the Mangekyō Sharingan in both his original eyes. With this dōjutsu, Kakashi can perform Kamui: a space-time technique that creates a barrier in the form of a swirling void that sucks any target he focuses his eye on to another dimension and also brings them back; even transporting them to a new location.

Each eye possesses a different variation of Kamui. With his left eye, Kakashi can perform it at long range to warp targets within his line of sight and without having to make physical contact. Initially, he lacked proper control to accurately hit moving targets. His skill and aim would later improve greatly, being able to successfully warp small, fast-moving, or multiple targets in rapid succession as seen against Pain, and Sasuke respectively. His finesse also allows him to safely warp chakra-based techniques, like the Rasengan or shadow clones without disrupting them, at such speed that Obito himself was fooled into believing the techniques were dispelled. Obito, who had mastered a variation of Kamui, openly acknowledged Kakashi's great skill with the technique. Kakashi has even attempted to use Kamui to behead the Demonic Statue of the Outer Path: an object of significant size and mass, multiple times, failing only because of external intervention. After learning of the connection between both eyes, Kakashi could later teleport himself with the left eye, and precisely choose a location to return to.

With his right eye, Kakashi can perform the short-ranged Kamui. With it, akin to intangibility, Kakashi can overlap any and all parts of his body with Kamui's dimension, making all other targets seamlessly pass through him and leaving him completely unharmed. When used in conjunction with offensive techniques, Kakashi can allow portioned parts of his body to remain tangible, while the rest intangible, to minimise the risk of counter-attacks. Kakashi is also very knowledgeable of the other Mangekyō Sharingan techniques as well as the risks the dōjutsu poses to the user's eyesight.

From manifesting the Mangekyō form in each of his own eyes and unlocking both Kamui variations between them, Kakashi also became able to perform Susanoo. While just recently obtained, Kakashi could fully manifest it and "stabilise" it into its Complete Body form. In this form, it is able to fly and despite its immense size, has enough dexterity to carefully hold someone in its hand and move about extremely fast. When needed, Susanoo can carry others inside it alongside Kakashi. It can also manifest a sword or shuriken, able to use the latter in unison with Kamui to warp whatever targets they hit to another location.

Because he is not an Uchiha, Kakashi's chakra requirements for his Mangekyō techniques is considerably higher, and initially he had to be hospitalised for a week after using it three times in one day. By the Fourth Great Shinobi War, Kakashi's mastery could use it five times, three of which in quick succession (along with multiple other chakra-taxing techniques) and still had enough strength left to fight and use it at least a few more times. Even after just starting to experience the immediate side effects, Kakashi quickly recovered from them somewhat. At the same time, repeated use of Kamui strained Kakashi's Sharingan, ultimately causing it to bleed and temporarily blur his sight, requiring him to get closer for better aim. After gaining the ability to manifest the Sharingan within his own eyes and some of the Six Paths power, Kakashi has no longer shown any visible burden on his chakra reserves from using Kamui, allowing him to perform the technique multiple times with no apparent problems.

Intelligence
Repeatedly, Kakashi has proven himself to be a very shrewd and resourceful man, regularly having his opinion asked for by Tsunade, the Fifth Hokage. While still a young child, Kakashi's instincts and experience could detect a hiding enemy's presence, impressing his sensei, Minato, and in the anime deceive Orochimaru, greatly injuring the Sannin in the process. Kakashi has even been noted to be smarter than Shikamaru Nara, a ninja well-known for his insightful and calculating nature. Kakashi is noted to be very persuasive speaker, though his arguments are more of a logical nature. He is very capable in deception, regularly using his opponents' own tactics against them. He is also adept at discerning the emotional nature of people and determining the source of their emotions as demonstrated in his thoughts about the adult Obito. Kakashi's intellect has proven itself against various S-rank ninja, showing undeniable perceptive and analytical skills, able to quickly and single-handedly deduce the workings of the most mysterious enemy techniques and near instantly plot successful diversions in order to verify his theories (most of the time proving them correct). He is aided, in this regard, by his calm personality, which allows him to handle a given situation with some detachment.

His long career as a jōnin, and formerly as an Anbu, have only expanded his knowledge, allowing him to handle virtually any situation. For these reasons Kakashi has been assigned to a variety of teams — always as the leader — and he is always able to work well with his team-mates. Chōza Akimichi attributes Kakashi's success to his approach to battles: he avoids direct combat by using misdirection and clones until he can determine the opponent's skills, at which point he modifies his tactics to fit the situation. Kakashi's leadership abilities were even acknowledged by Hagoromo Ōtsutsuki. Kakashi has also shown repeatedly to be a highly capable teacher. He has come up with various unorthodox methods to help his students produce impressive leaps in their abilities in weeks what would normally take months if not years of intense training.

Chakra Prowess
Kakashi is noted to have very strong chakra, able to be visibly seen by the naked eye when focusing enough of it. Despite the natural strength of it, originally, Kakashi's primary weakness was his reserves of chakra and stamina being average. He could only maintain his Sharingan for a short time, quickly tiring out from overusing it and ultimately collapsing if used too long, followed by great difficulty to even stand for days. He also could only use his signature technique, Lightning Cutter, four times in a single day. To somewhat compensate for these limited reserves, Kakashi possesses very refined chakra control, allowing him to use multiple techniques quickly with the minimum necessary chakra and to their highest level. Kakashi's control also allows him to perform various techniques, usually lightning-based, with few to no hand seals, leaving little time for enemies to react.

Over time, Kakashi's chakra reserves improved considerably to extend his timespan and versatility to fight multiple high-level opponents. By Part II, he can maintain his Sharingan for an entire day and utilise several chakra-taxing techniques in quick succession unfazed, including his Lightning Cutter at least six times and in each hand simultaenously. His chakra reserves development is best seen with his Mangekyō Sharingan technique, Kamui. Originally, a single use tired him greatly and using it more than twice in a single day left him crippled for over a week. By the time of the Fourth Shinobi World War, he was able to fight throughout an entire day right before going to fight against Tobi and his Six Paths of Pain which comprised of reincarnated jinchūriki. Once arriving, he was able to use Kamui several times in quick succession before finally collapsing as his eye started bleeding. Shortly afterwards, he recovered enough to stand up on his own and soon leapt back into action, using Kamui yet again, along with several other chakra-taxing techniques.

After Obito's death, along with the power of his dōjutsu, he gave to Kakashi his chakra and the Six Paths Power he received as the Ten-Tails' jinchuriki. From these gifts, Kakashi's chakra reserves became great enough to manifest a Complete Body — Susanoo and use Kamui multiple times with no signs of fatigue. It can also augment his techniques.

Other Skills
A man who epitomises versatility, Kakashi's expertise is not limited to the three major ninja skill sets; he is renowned for his tracking abilities and has otherwise displayed proficiency with trap-making, medical, survival, escapism, stealth, subterfuge, and assassination. Kakashi is also noted to have a better sense of smell than Kiba Inuzuka did in Part I, a noteworthy member of a clan with canine-like senses. Even without sight, Kakashi is still a highly formidable fighter, able to use his other senses and knowledge of his surroundings, allies, and enemies to perceive the situation and overwhelm his opponents. Kakashi has also developed considerable prowess in fūinjutsu, something that Orochimaru found impressive given Kakashi's age.

Prologue — Land of Waves
Kakashi later learned of his next potential Team 7 — which consisted of Naruto Uzumaki, Sasuke Uchiha, and Sakura Haruno. In the anime he visited their homes accompanied by Hiruzen. Kakashi was chosen specifically by Hiruzen Sarutobi to be the leader of Team 7 because of Naruto and Sasuke. Kakashi's duty in addition to training the team was also to keep the Nine-Tails in Naruto contained. As for Sasuke, Kakashi was tasked with ensuring the rage-filled ninja does not tread a dark path plus help him awaken and master his Sharingan, since they had similar traits that would allow Kakashi to better understand him. Kakashi questioned Hiruzen about the nature of his team, who voiced his belief that Kakashi could help them understand true team-work. He was also met with by Tenzo, who noted a positive change in Kakashi and reminded his senior he was late to meet his new students. Upon meeting them, noticing that an eraser was set up to hit him as a prank, Kakashi let it happen to test his new students' respective personalities and was displeased, noting no signs of teamwork.

During the test, each of the young ninja try their own methods to getting a bell, only for Kakashi to easily defeat them. After Team 7 failed their test, Kakashi was quick to express his displeasure at their performance and that true goal was team-work. After explaining the importance of team-work and seeing how ashamed they were at their performance, Kakashi decided to give Team 7 one more chance to act as a team, and let them take a break for lunch. However, Naruto, having earlier tried to steal their lunches, was forbidden to eat with a severe penalty for anybody feeding him. When he watches Sasuke and Sakura giving Naruto their food to have him in peak condition from afar, he was amazed at the sudden change, impressed with their decision and decided to test their commitment. Determined to make his rookie team proud, Kakashi immediately confronted them while feigning anger. As the trio defiantly stand up to him on the grounds that they are a team, a delighted Kakashi passes them on the ground they placed loyalty amongst comrades first, finally able to start putting his own demons to rest.

After completing a number of D-rank missions, Team 7, at Naruto's insistence get assigned a somewhat more difficult C-rank task of escorting the bridge-builder Tazuna to the Land of Waves. Noticing they were about to be ambushed en route by the Demon Brothers, Kakashi faked his death to determine if their target was his team or Tazuna. Easily defeated them upon seeing them attempt to kill the bridge builder, Kakashi realised that Tazuna has not been completely honest of the mission and threatens Tazuna to tell them the truth. After hearing Tazuna's goal to build a bridge to free his country from the tyranny of Gatō, despite the mission now being more of an A-rank or B-rank, Kakashi decides for his group to remain until the bridge was complete.

Upon arriving in the Land of Waves, Team 7 was attacked by Zabuza Momochi, a missing-nin of Kirigakure and former Seven Ninja Swordsmen of the Mist member who is under Gatō's employment. Despite his Sharingan, combined with his need to protect his students from the more experienced ninja, Kakashi finds himself trapped in a water prison. Luckily, Naruto and Sasuke orchestrate a gambit to free him. From there, using both his Sharingan and psychological warfare, Kakashi placed Zabuza at a disadvantage until a young Kirigakure hunter-nin named Haku stepped in and appeared to kill Zabuza before dragging him away for disposal. While forced to recuperate from his Sharingan overuse, Kakashi realises that Haku might have faked Zabuza's death to save him, deciding to train Team 7 in perfecting their chakra control for a week until they can resume bodyguard duty.

Once at the bridge, Kakashi's suspicions are confirmed when Team 7 is confronted by Zabuza and Haku. While their wards battle, Kakashi once more battles Zabuza as he learned to counter him with his Hiding in Mist Technique to keep him from falling prey to Kakashi's Sharingan. In response, Kakashi summons his ninken underground to locate and pin down Zabuza to finish him off with a Lightning Cutter. However, Haku uses himself as a human shield and took the fatal blow intended for Zabuza. But despite Haku's sacrifice, Kakashi had the upper hand until Gatō and his crew arrive to wipe out everyone. After seeing the gravely wounded Zabuza managing to kill Gatō, Kakashi used his Multiple Shadow Clone Technique to scare the other criminals. As Zabuza died, he asked Kakashi to bring his body beside Haku's before he passed away. As Naruto tells Kakashi Haku was born in a "snowy village", Kakashi believes Zabuza really will go to where Haku has gone. Kakashi buried them alongside each other before returning to Konoha with Team 7, as the bridge is completed.

In the anime, Team Kakashi noticed an Anbu team escorting a street performer into the village who Inoichi revealed was intact a ninja from the Jōmae Village. After learning Kakashi had history with Hanare, he decided that he would gather intel on her. As Kakashi began to get Hanare to open up, she revealed how she met Kakashi. Kakashi's students who were spying, came crashing out of the tree, landing on Kakashi and Hanare causing them to accidentally kiss, and in the process revealing his Sharingan. Later, Konoha received word that the Jōmae Village had captured a Konoha ninja and demanded an exchange for Hanare. At the exchange, a trap was set, forcing both sides to engage in battle leading to Kakashi going after Hanare. Upon cornering her, Kakashi revealed that he knows Hanare has a special mind reading technique that lets her look into an individual's mind and used it to read Inoichi's mind while he probed her. Kakashi realised this when his Sharingan was accidentally revealed and copied her technique. After expressing her enjoyment while in Konoha, Kakashi decided not to kill her and chose to let her go.

Later in the anime, a ninja named Sabiru proposed a new defence system for the village while Kakashi was one of the guards for the meeting for the proposed plan. While Kakashi and the Third Hokage had their suspicions, the council was about to vote to pass Sabiru's proposal but were interrupted by Kisuke Maboroshi, an Anbu who suspected Sabiru of treason. After learning that it wasnt infact Kisuke, Kakashi followed him as the imposter ran. After learning the intruder was Naruto, the two worked together and tricked Sabiru into confessing his crimes but an unknown assailant killed him before they could take action.

Later in the anime, Team 7 was assigned to retrieve a golden statue stolen by bandits and decided to ambush them, leading to Kakashi going solo while his students attacked from a separate location. After reuniting, Kakashi speculated that Naruto and Sasuke after they recoverd the statue, could of melted it, in an effort to restore it. After the 2 got stuck to each other by Jako's, liquid chakra tecnique, they bickered for a few days while Kakashi smiled to himself at how far their bond has come despite their differences.

Chūnin Exams
Feeling his students were ready, Kakashi entered Team 7 in the Chūnin Exams, despite some initial disapproval from other elite ninja. After Sasuke was branded with the Cursed Seal of Heaven by Orochimaru during the exam's second phase, unable to remove it, Kakashi used the Evil Sealing Method to try and prevent its usage. Following the preliminary matches, Kakashi decided to personally train Sasuke for a month after realising how much Orochimaru desired Sasuke from his subordinate Kabuto Yakushi attempting to abduct him. Kakashi tried to reinforce Sasuke’s self-worth and value for his friends by teaching him how to use Chidori as a deterrent against the cursed seal. As the training also involved taijutsu training copied from Rock Lee to better condition Sasuke's body for the Chidori, Kakashi runs late in delivering Sasuke to his final round match.

Konoha Crush
When Sunagakure and Otogakure's Konoha Crush began during Sasuke's match, Kakashi released a genjutsu along with Might Guy and Sakura, and helped repel the invaders along with Guy. They ended up having several contests to see who could defeat the most Suna and Oto-nin, although Guy usually won. When he noticed that Sasuke was going after Gaara, Kakashi sent Naruto, Sakura, Shikamaru Nara, and Pakkun to stop him and bring him back. After defeating several Suna and Oto-nin, he is briefly seen with Guy, Aoba and Kurenai. After the failed Invasion, he attends Hiruzen's funeral, mourning his loss, he listens to Iruka's words at the funeral and thinks how sad it would be if the Third Hokage had died for nothing.

Search for Tsunade
Shortly after the invasion was prevented, Kakashi comes to the aid of Asuma Sarutobi and Kurenai Yūhi when they nearly got killed by Itachi Uchiha and Kisame Hoshigaki when they arrived to the village. Having learned of Akatsuki from Jiraiya, Kakashi was able to hold his own against Itachi until falling to his opponent's Tsukuyomi. Severely weakened by the technique, Kakashi confirmed that Itachi and Kisame are after Naruto before losing consciousness. Before they could take him, Kakashi is saved by Guy's arrival with the Akatsuki members driven off. Kakashi was left in a coma after what happened, and was not revived until Tsunade returned to the village. Immediately after recovering, he was sent on a new mission.

In the anime, one of his missions was to survey the Valley of Judgement for an eye medical plant. Later, Kakashi and Guy discovered Naruto, Sakura and Neji looking for the plant to aid Hinata's eye recovery. When the genin were attacked by the inhabited people, Kakashi and Guy acted, driving them away. Afterwards, Kakashi stated that there was no point pursing the plant as the people of this valley have spent countless years there to the point they have lost their eyesight and afterwards returned to Konoha. In another mission, to further strengthen the new alliance between the Konoha and Sunagakure, Team Kakashi joined a Suna ninja team that included Gaara. On their way to their mission, they were attacked by a group of Suna ninja determined to kill Gaara. While understanding their intentions, Kakashi did not agree with them and attacked. After defeating the enemy, Kakashi and his team made their way to the bandit's stronghold and destroyed it, succeeding in their mission.

Later in the anime, Team 7 went on a mission with Team 10 to rescue the granddaughter of a Village Headman who was kidnapped by bandits under Baji command. After being taken to the entrance cave of Baji's headquarters by a former member named Tōfu and learning the layout of the their base, it was decided between Kakashi and Shikamaru to only have the jōnin enter while the genin stay behind. Once Kakashi and Asuma reunited back with the genin and learned of what they got up to in their absence, Kakashi congratulated Shikamaru for his plan and succession in completing the mission. Later, Tsunade assigned Team 7 a mission to locate and discover the plans of a missing-nin named Sadai. It was decided that Kakashi would take Sasuke alone for this mission while Naruto and Sakura were sent to escort Naho who was a relative of the Fire Daimyō. Later, Kakashi and Sasuke found and infiltrated Sadai's base where they learned he planned to kidnap Naho. With Pakkun's help they were able to find Naruto and Sakura's trail, but not before they were taken captive by Sadai's gang. With the scents mixed up, Kakashi summoned another ninken and split up with Sasuke following Pakkun. Sasuke ended up finding Sadai first. Kakashi arrived in time to stop Sasuke from beating Sadai to death, reminding Sasuke they should bring him back for questioning. Still steaming, Sasuke left and returned to the village, much to Kakashi annoyance.

Sasuke Recovery Mission
Before setting out on his mission, Kakashi stops a battle between Naruto and Sasuke. Learning that Sasuke had relapsed into desiring revenge, Kakashi lectures the youth that the Chidori was designed to protect friends — not attack them. Despite encouraging Sasuke to place greater importance on friendship, Kakashi learned upon his return that his student has defected and a squad of genin, led by Shikamaru, has been sent out to retrieve him and deal with Orochimaru’s Sound Four. Ignoring the fact that he had a new mission, Kakashi rushed out to track down Sasuke and the retrieval team. Using his ninken, Kakashi was able to locate a defeated Naruto, with Sasuke long gone. Unable to pursue Sasuke because of a fresh rainfall and due to Naruto's current condition, Kakashi took Naruto back to the village to recover, saddened that he failed to help his students.

Mizuki Tracking Mission
In the anime, when each of Kakashi's students became the apprentice of one of the Sannin each, it effectively disbanded Team 7. As such, Kakashi returned to performing several high-ranking missions or training to further refine and enhance his abilities for the inevitable battle against Akatsuki for the next three years. During one of his returns from a mission, arrived in time to recapture some of the prisoners that had escaped from prison when Mizuki led a breakout.

Cursed Warrior Extermination Mission
In the anime, he was sent to assist with the Cursed Warrior incident in the Land of Birds. While not officially his mission and arriving much later, Kakashi realised the situation wasn't as it seemed, and ultimately took command of the team, thereby deciding to investigate. This led to Kakashi's fight with Hōki's minions, Nagare and Hokushin, whom he defeated with relative ease.

Sunagakure Support Mission
In the anime, Kakashi was sent to spy on the Takumi Village when rumours of an uprising reached Konoha. There, he discovered the entire village abandoned, and the corpses missing. He later showed up as reinforcements, along with Jiraiya, to aid Naruto and the rest of the genin in helping Sunagakure, only to discover that Naruto's team had already successfully completed their mission.

In Naruto's Footsteps: The Friends' Paths
In the anime, about two years later, to help restore Konoha's reputation after Orochimaru ruining the last exams, Tsunade and the newly appointed Kazekage: Gaara decided to host together an early Chūnin Exams with a second secret agenda of hoping to lure out the Akatsuki. As Kakashi assisted Tsunade in setting this up, Kakashi was also instructed to personally deliver an invitation for the impromptu Chūnin Exams to Amegakure, using this as an excuse to enter the village with less suspicion while Kakashi would investigate the rumour circulating around the village. Upon arriving at the village, he was quickly halted by the guards. After convincing them he was here on civil business, he was allowed to meet with Hanzō and deliver the invitation, unaware that it was actually Konan in disguise. Afterwards, while seemingly leaving the village, Kakashi snuck back in to begin his mission. Almost immediately, however, Kakashi realised guards were looking for him and while they didn't know it was him specifically or where he was, the guards were clearly aware of his activity from the beginning. Deciding to play it safe as Tsunade ordered, Kakashi quickly escaped the village and reported to the Hokage upon returning to Konoha.

Kazekage Rescue Mission
Knowing that Naruto would return soon from his training under Jiraiya, Kakashi was tasked by Tsunade to test the genin's improved skills along with Sakura and her training under Tsunade. After Naruto's return to the village, he gave Kakashi the newest edition to the Icha-Icha series, much to his glee. Later, Kakashi had Naruto and Sakura take another bell test, with the real objective being to actually capture the bells, to see how much they have improved. When they were unable to get close enough to Kakashi to each take a bell, Naruto and Sakura resorted to trying to spoil the plot of the most recent Icha-Icha novel, throwing Kakashi off guard and allowing them to take the bells.

When word reached Konoha that Gaara had been kidnapped by Akatsuki, Team Kakashi was sent to rescue Gaara. Upon arrival in Sunagakure, they are teamed with Chiyo before following Akatsuki's trail. Along the way, they encountered Itachi. As Kakashi was able to fight on even grounds, he noticed that Itachi's performance wasn't somewhat off. With a well-timed manoeuvre, Kakashi was able to trick and restrain Itachi, giving Naruto the opening needed to finish the fight with his Big Ball Rasengan. Afterwards, they discovered that the Itachi was only a lookalike. They then met up with Team Guy, which was sent as back-up to Team Kakashi, outside an Akatsuki lair. Because there is a barrier over the entrance, Team Guy went to take down the barrier. This allowed Team Kakashi to infiltrate the lair, where they found Sasori, Deidara and Gaara.

Deidara flew off with Gaara's body, with Naruto and Kakashi in pursuit, leaving Sasori to Sakura and Chiyo. While pursuing Deidara, Kakashi tried to use his Kamui in an attempt to remove his head, but his aim was too poor and he was only able to sever an arm. Nevertheless, Naruto was able to retrieve Gaara. With Naruto successful, Deidara tried to use a Suicide Bombing Clone to escape. Kakashi used Kamui again to get rid of the explosion, saving himself and his allies. Having recovered Gaara's body, Chiyo transferred her life to revive Gaara. With Team Kakashi and Guy completing their mission, they return home. Because Kakashi used Kamui too much, Guy prompted to carry him on his back, to the disgust of the rest of the two teams except for Lee who offered to do the same with Neji. Afterwards Kakashi is left bed-ridden for a week.

Tenchi Bridge Reconnaissance Mission
Kakashi, a bit disorientated, was brought back to Konohagakure by Guy and rushed to the hospital to recover from the strain of using his Mangekyō Sharingan. Ordered bed rest for at least a week, Tenzo, now working under the codename "Yamato", goes in his stead as Team Kakashi's leader to capture Sasori's spy. Before the mission began, Kakashi learned the horror that awaited if Naruto was allowed to reach the fourth-tail of the Nine-Tails chakra cloak; Jiraiya had received a near-fatal blow to the chest during training with Naruto in that form. He was later hooked up to an IV, complaining that he wanted to eat solid foods.

Akatsuki Suppression Mission
After resuming training with Naruto, Kakashi revealed that this training was to allow Naruto to combine his Wind chakra with his Rasengan to create a brand new technique attempted by the Fourth Hokage; to demonstrate his point, Kakashi showed Naruto that he could perform the Rasengan as well, but couldn't add his Lightning chakra to it. Upon hearing that Asuma Sarutobi had been killed in a battle with Akatsuki, Kakashi decided to lead Team 10 in avenging him, as Naruto had already advanced in his training beyond needing Kakashi's assistance. He left Yamato in charge of overseeing Naruto's training, and had Shikamaru work with him in the plan of attack.

When they located Akatsuki members Hidan and Kakuzu, Shikamaru and Chōji engaged the two, allowing Kakashi to observe from a distance and waited for an opportunity to join the battle. Before the Akatsuki pair could make a counter attack, Kakashi impaled Kakuzu with his Lightning Cutter and took some of his blood, as per Shikamaru's strategy. Believing to have killed him, Kakashi focused his attention towards Hidan but was intercepted by Kakuzu and attacked. Kakuzu revealed that he had a total of five hearts, one of which (the earth heart) Kakashi had already destroyed. Beginning their counterattack, Kakuzu took advantage of his partner's immortality and attacked the both while Kakashi was preoccupied with Hidan. After blocking Kakuzu's lightning attack, Kakashi fought Hidan again while being attacked by Kakuzu's hearts which launched a barrage of elemental techniques at Kakashi. Unable to assist Team 10, Kakashi created a shadow clone and used it as a decoy while he came to their aid.

Regrouping, they realised that the Akatsuki duo were seemingly unstoppable when together, so the team decided to separate them, with Kakashi handing a capsule filled with Kakuzu's blood to Shikamaru and the latter leading Hidan away. Confronting Kakuzu head on, Kakashi was overwhelmed by his elemental combinations and eventually was pinned down by Kakuzu. Before being able to steal Kakashi's heart, Kakuzu lost his remaining water heart to Shikimaru's strategy after Kakashi's had given him the capsule of blood to use in his partners curse technique. While Hidan fell to Shikamaru, Kakuzu intended on taking Kakashi's and the remaining members of Team 10's hearts to replace the ones he lost, with three hearts remaining intact. In the nick of time, Naruto and the rest of Team Kakashi came to their aid.

Using his new Wind Release: Rasenshuriken, Naruto was able to crack Kakuzu's fire and wind hearts, leaving Kakuzu defeated. This gave Kakashi the opportunity to finally finish the Akatsuki member off with another Lightning Cutter. As Kakuzu wondered how he could have been defeated by the likes of them, Kakashi told him before killing him how the next generation will always surpass the current one. Kakashi along with Yamato are later summoned to Kakuzu's autopsy by Tsunade who labels Naruto's new technique as a kinjutsu and orders that he never uses it again because of the detrimental side-effects. Afterwards Kakashi finds Naruto at Ramen Ichiraku and ends up having to feed him his noodles. As Kakashi attempts to tell him what Tsunade says, Naruto interrupts him telling him not to stop him from progressing.

Itachi Pursuit Mission
When word of Orochimaru's defeat at the hands of Sasuke reached Konoha, Kakashi tried to make another attempt at retrieving Sasuke. He assembled the members of Team Kakashi and Team Kurenai (minus Kurenai) into an Eight Man Squad, and set out to locate either Sasuke or his brother, Itachi.

Fated Battle Between Brothers
Kiba and Naruto were eventually able to find Sasuke's location, and the team gave chase, only to be delayed by Tobi. Their efforts to attack Tobi all proved futile because of Tobi's unique teleporting technique. It was not until Zetsu reported to Tobi that Sasuke had killed Itachi that they were able to continue their pursuit. Before Tobi disappeared, Kakashi noticed, to his shock, a Sharingan on Tobi. Despite the team's haste, Tobi got to Sasuke first and, having lost the trail, were forced to return home.

Pain's Assault
Kakashi was present in Tsunade's office where Fukasaku told the room at large, including Naruto, that Jiraiya was killed by the leader of the Akatsuki. Kakashi left Naruto alone to mourn for his loss but later helped the decoders decipher Jiraiya's message using a clue from the latest Icha-Icha instalment, much to Kakashi's extreme discomfort and Shikamaru's embarrassment. While Naruto left the village to learn senjutsu, Kakashi prepared himself for an Akatsuki attack.

When Akatsuki's leader, Pain, attacked Konoha in search of Naruto, Kakashi confronted Pain's Deva Path, after realising that the initial attack was a diversion. After saving Iruka Umino and letting him escape, Kakashi immediately brakes his chakra rod and erects a wall to corner him. The Deva path then impales Kakashi with his Chakra Disruption Blade, resulting in Kakashi missing his target with his his Lightning Cutter. Pain commented that is what an honour meeting the copy ninja and asked where Naruto was. Refusing to answer, Kakashi attempted to attack Pain with his Lighting cutter again, only to be repelled by a gravitational-manipulation technique, causing a huge explosion which was noticed by Chōza Akimichi's group.

After being buried in ruble from Pain's last attack, Kakashi created a clone to analyse his opponents ability. The clone started off by launching an attack at the Deva Path, only to be repelled and relises that not only physical attacks could be repel but also ninjutsu. After wondering how he could combat the issue, he was approached by another akatsuki to aid the Deva Path. His new opponent immediately fired rockets towards Kakashi. After dodging the attacks, Kakashi used the dust to sneak behind the Asura Path and attempted to attack his blind spot, but was puzzled when he dodged. After noticing that the other Path had been watching from a distance, Kakashi remember'd that all the paths vision were linked. After retreating a few feet, the Deva Path began using a similar gravitational ability as before, but instead Kakashi began being pulled towards his opponent.

Unable to resit the force, Kakashi gets impaled by the Asura Path, leading to the clone stunning his attacker before dispersing. After being distracted by the clone, Chōza managed to seamlessly defeat the Asura Path. Having being backed up with reinforcements, Kakshi emerges from the rubble and rejoins the fight. After commenting that he had already used over half his chakra, the Deva Path advances towards the group and repels all their attacks and defeat everyone except Chōji and Chōza. After figuring out the Deva Path's powers, Kakashi devised a plan, and used Chōji and Chōza's help to take down the Deva Path. Kakashi then buried chains in the ground and waited for their opponent to approach. When the Deva Path was close enough, Kakashi attacked from underneath but was repelled, leading to Chōji and Chōza to attack. After they found themselves being repelled, they implement Kakashi strategy and restricted the Deva Path's body with chains. Having successfully initiated the plan, Kakashi attempts to finally defeat their opponent but was intercepted by the Asura path, who took the attack instead. Having enough time to use his ability again, the Deva Path repelled everyone.

Trapped and unable to move, the Deva Path notes that he is too great of a threat to be left alive. Taking caution not to approach Kakashi, he sends a nail flying towards Kakashi from a distance, to which Kakashi activates his Mangekyō Sharingan and warpes away the nail with Kamui. Not having noticed Kakashi intervention, the Deva Path leaves believing all his opponents are dead. When he came to, Kakashi sent Chōji to tell Tsunade about the Deva Path's abilities. But as Chōji left, the still-active Asura Path launched a missile at him. Despite knowing that he was almost out of chakra, and would likely die if he used his Mangekyō Sharingan again, Kakashi used Kamui to dispose of the missile and save Chōji. Having expended the last of his chakra, Kakashi died, and his soul left his body. He lamented on how he failed to protect Rin and soon found himself at a campfire with his deceased father, Sakumo, to whom he tells his life story upon request from his father.

During Pain's destruction of Konoha, Kakashi's body was protected by one of Katsuyu's divisions. After finishing the recount of his life, he stated that he finally understood why his father had chosen to save his friends and was now proud of him for it. Their conversation was halted when a ray of light beamed down upon Kakashi, as a result of Nagato's Samsara of Heavenly Life Technique. Before seeing his son depart, Sakumo thanked Kakashi, and declared that he would now be able to join his wife. Kakashi then woke up in the Konoha battlefield, with Chōji shocked. As Kakashi wondered what happened, a Katsuyu division explained to him the series of events that had occurred. After the invasion came to an end, Kakashi fetched Naruto and brought him back to a massive welcoming party at Konoha. There, he complimented Naruto on finally achieving his goal to be accepted and appreciated by the whole village.

Five Kage Summit
When news reaches Konoha of Sasuke's actions in the Land of Lightning, Naruto asks Kakashi and Yamato to take him to the Land of Iron so that he can ask the Fourth Raikage to forgive Sasuke. Before leaving, Kakashi asks Sai to keep their departure a secret from Danzō, the acting Hokage while Tsunade is in a coma. They locate the Raikage, but Naruto is unable to convince him. During their stay at a motel in the Land of Iron, Tobi confronts Naruto. Having expected him, Kakashi and Yamato attack him. Knowing the attacks will have no effect, Tobi tells them about Sasuke's motivations, the Sage of the Six Paths, the Uchiha clan, and the truth of Itachi. Kakashi then asks what Tobi's own motives are, but receives only the answer of "to be complete" before Tobi disappears.

Sai and Sakura follow Naruto to the Land of Iron and Sakura tells Naruto that she loves him and Kakashi watches on in disappointment and stops an angered Yamato from interrupting, trusting Naruto to handle it. Like Naruto, Kakashi suspects that this is not the real reason they came, which is confirmed by one of Sai's ink clones. Sakura, as agreed upon by the other members of the Konoha 11, is going to kill Sasuke before he involves Konoha in a future war in any way possible. Knowing that she is no match for Sasuke and possibly understanding that he is most likely the only one who can reason with her in her current mental state, Kakashi prepares to follow her. At that moment, Gaara arrives and tells them about the start of the Fourth Shinobi World War and Danzō's actions at the Kage Summit. He adds that the other Kage would prefer if Kakashi were the Hokage. When Gaara leaves, the ink clone guides Kakashi to Sakura.

The ink clone disperses en route when Sakura neutralises the real Sai. Kakashi finds her in time to stop Sasuke from killing her and tells her that, as Sasuke's teacher, and believing himself to be the cause for the team's falling out after once making after an empty promise to her that everything would be okay, he will be the one to kill him. Kakashi makes one final attempt to draw Sasuke away from a life of vengeance, but Sasuke menacingly responds by saying that only by bringing his entire clan back would he stop. Kakashi tells Sakura to leave with Karin while he fights Sasuke, and contemplated his feelings being the same as the Third Hokage's with Orochimaru. Their fight soon led off the bridge they were on and Kakashi receives an attack from Sasuke's Susanoo. Kakashi is forced to use Kamui to divert the attack, which leaves him unable to protect Sakura when she rejoins the fight. Naruto arrives in time to save her, and furious at Sasuke's mercilessness, Kakashi tries to finish him off. Naruto halts Kakashi in order to speak with Sasuke, who gloats about having killed Danzō. Tobi and Zetsu soon arrive and Kakashi, at Naruto's request, allows them to leave with Sasuke without incident. Kakashi tries to take out Tobi with Kamui, but Tobi tells him that the technique won't work on him. Tobi teleports away taking Sasuke, and Zetsu leaves then as well. Kakashi collects Karin, believing she may have useful information, and revives Sai and Sakura's other escorts. They are then met by members of Root. Learning that Danzō was truly dead as the seals he placed on all of his subordinates have vanished, Kakashi and his team decided to quickly to return to the village knowing that Kakashi would most likely be made the new Hokage.

Fourth Shinobi World War: Countdown
Upon returning to Konoha, Kakashi brings Karin to Ibiki for questioning. Kakashi spoke with Koharu Utatane and Homura Mitokado about all that had occurred. While reluctant, he agreed to their decision to make him Hokage as the Allied Shinobi Forces would need a Kage from each of the Five Nations and Kakashi already had full trust and respect from the other Kage. In the anime, word quickly spread about Kakashi being appointed the Sixth Hokage. Happy for his long-time friend and rival, Guy challenged him to a race, which resulted in Kakashi's 50th win over Guy. Soon afterwards, Kakashi was taken to the Stone Carvers of the Hokage Monument to make a replica of his face to carve his likeness on the monument.

Later, he accompanied the Konoha Council to a meeting hall with the Fire Daimyō and his delegation. Despite a unanimous vote for Kakashi, moments before he was officially declared the Sixth Hokage, news reached them of Tsunade waking up, ending the proceedings. Later, while Tsunade was recovering, Kakashi spoke with her and thanked her for waking up in time, noting he was not cut out for the position of Hokage.

Fourth Shinobi World War: Confrontation
Kakashi was later appointed as commander of the Allied Shinobi Forces' Third Division. As he and the other generals stood over their battalions he urged Gaara as the Regimental Commander to say a few words to them. As two ninja on the brink of infighting began to bicker, Kakashi watched on noting that he had a feeling something like this would happen and as Gaara parted them and spoke to the masses Kakashi noticed the change in atmosphere around the ninja. Later on while Kakashi was with his division, he saw the ambush squad set off a red flare. He then ordered his division to go to the Surprise Attack Division. They arrive in the nick of time and save Sai, Omoi, and Zaji from danger.

Much to Sakura and his surprise, they find Zabuza and Haku amongst the enemy ranks. Zabuza and Haku ask how Naruto is doing, and Kakashi remarks that Naruto has become an admirable shinobi. However, their reunion is cut short when Kabuto strengthens his grip on the resurrected shinobi, completely eradicating their personalities. Before completing losing control of themselves, Haku and Zabuza pleaded for Kakashi to stop them, with Kakashi agreeing as he revealed his Sharingan. As Zabuza used the Hiding in Mist Technique, Kakashi orders his squad into a Manji Formation around the sensor ninja. When Kakashi's division is about to mount a counter-attack, he watches in exasperation as the previous generation of the Seven Ninja Swordsmen of the Mist is summoned to the battlefield. As the swordsmen begin to thin the division's numbers, Kakashi comes up with a plan to neutralise the Hiding in Mist Technique used by Zabuza. He tries to impale Zabuza with a Lightning Cutter, only for Haku to take the blow. Zabuza then seizes the opportunity to attack the immobile Kakashi.

Kakashi narrowly dodges the strike with only a shallow wound, which fully regenerates Zabuza's Kubikiribōchō, while Haku was bisected at the waist. As Kakashi reflects on how this situation was just like their last battle, he remembers how Zabuza and Haku taught Naruto an important lesson in bonds. Kakashi openly thanked them for being Naruto's first opponents. Also remembering how Kakashi had grown to respect and like the two rogue ninja, Kakashi became determined to free them from their undead prison in respect for the way they chose to die. Kakashi then ordered his men to prepare the strategy again as Kakashi charged forward, using his Lightning Cutter to destroy Zabuza's sword-wielding arm and stab him through the chest. Kakashi's team then used special bounds to trap them, also causing the mist to dispel. Openly voicing his anger at how someone could toy with the dead, he states that he will going on a rampage as he picks up Kubikiribōchō to use.

On the next day, Kakashi and his division resume the battle against the remaining Mist Swordsmen. In the anime, he defeated Jinin Akebino, giving his team time to seal him. Later, he encountered Jinpachi Munashi and Kushimaru Kuriarare toying with members of Kakashi's division. While able to save some of them, he soon found himself cornered by the two swordsmen. Might Guy than arrived to aid Kakashi. Taking advantage of the swordsmen's lack of team-work, they were able to hold them off until the sealing team arrived to subdue them.

Fourth Shinobi World War: Climax
Later, Kakashi faces Fuguki Suikazan. He cuts down the Mist Swordsman by imbuing the Kubikiribōchō with lightning, allowing Sai to seal Fuguki inside of his drawing. After noticing more White Zetsu Army clones arriving, he tells Guy who wanted them to take them down all at once that they also had reinforcements after seeing Naruto's clone arrive on the battlefield.

After dealing with the remaining Mist Swordsmen, Kakashi and Guy head on to save Naruto from being captured by Tobi. Attacking him once he materialised, Kakashi was able to retrieve Naruto before Tobi could warp him away. Smiling at his pupil, he tells him that he couldn't sit idly by while his student overexerts himself. Deciphering the information Naruto had spewed out, he watches on as the Five-Tails charges at Tobi and theorises that Tobi did not have perfect control of the beasts before telling Naruto to stay focused. As the beasts charge at them, Kakashi tells Guy that they needed to decipher which beast used which of the Six Paths of Pain's abilities. Activating his Lightning Cutter, he and Guy confront the beasts head on, he is shocked to see that they aren't using these abilities. He and Guy later watch in shock as Tobi, after congratulating Kakashi on his observation skills, causes Utakata and Rōshi to fully transform. As the Six-Tails attacks breathing out a corrosive gas, Kakashi warns Guy not to touch the substance it spewed at all.

As they retreat, Guy alerts him to Naruto's predicament. Telling Guy that they weren't able to leave to free Naruto from Son Gokū's jaws as they were being pressured from all sides, he creates a shadow clone and assumes the Manji Formation. Entrusting their backs to one another, Kakashi and his clone charges forward with the Lightning Transmission technique, severing the chakra arms. Kakashi prepares for another onslaught of attacks as the beasts confront him head-on. As Naruto succeeds in releasing Son from Tobi's control, both Kakashi and Guy look on shocked as the now fully-transformed jinchūriki bear down on them.

As the situation becomes dire, Kakashi decides that he would warp away the five Tailed Beast Balls that were aimed at them, but Guy tells him that there was no way he had enough strength for that. Kakashi also declines Guy's decision to use the eighth gate, stating he would die after opening it. Both men are rescued however by Naruto who deflects the attacks with such speed that Kakashi momentarily believes him to be his former teacher Minato. Absorbed into Kurama's chakra as Naruto transforms, both men watch on at the battle between the beasts ensue watching in horror as the five opposing beasts later combine a Tailed Beast Ball, and Naruto attempts to counter with his own.

After Naruto's Tailed Beast Mode was cancelled, Kakashi stands alongside Guy, who uncharacteristically says that he felt old seeing Naruto come so far which somewhat shocks Kakashi. Kakashi then tells him that their youth wasn't over just yet which seemingly gets Guy back to his old self. He is later seen mobilised beside Might Guy, Naruto Uzumaki and Killer B in his full Eight-Tails form preparing to assault Tobi and the Demonic Statue of the Outer Path. Launching an attack with his shadow clone, Kakashi called to Guy who followed up with an attack followed by B and Naruto, the latter of which continued to taunt Tobi despite his advisement against it.

While Naruto and Guy battle Tobi, Kakashi focuses on the Demonic Statue of the Outer Path. Kakashi then tries to use Kamui on the the statue to remove it's head, however the statue seems to have nullified the attack which confuses Kakashi. He then infuses a kunai with Lightning Release and calls out to B to launch him. Launching across the battlefield, Kakashi easily cuts through a rock that separated him from Naruto and launches the kunai at Tobi who becomes intangible and kicks the kunai towards Naruto. Kakashi uses Kamui once again to warp away the kunai. Regrouping as the last attack seemingly fails to land, the shinobi wonder how they were going to defeat Tobi.

Noticing the slight crack in Tobi's mask, Kakashi denies the fact that it was made by Naruto's last attack, and noted that the crack was too sharp to have been made by an impact like that. Realising what had made the gash in the mask, Kakashi called out to his comrades to aid him in testing his hypothesis. Climbing into B's hand the three shinobi are launched across the battlefield, and after Guy and Naruto respectively attacked Tobi, just before the masked man phased through Naruto's Rasengan, Kakashi used Kamui to send the Rasengan to the other dimension. Tobi's right arm was then subsequently hit by an unseen attack at which time Kakashi declared that his hypothesis was right and realised that Tobi was not using two separate techniques to warp himself away and another to phase, but one single technique.

Obliging Guy's request to tell them his analysis in the simplest way possible, Kakashi explains what occurred that Tobi only intangible by transferring part of himself into the other dimension where Kakashi sends whatever he targets with Kamui to. But as this other dimension is pointed out as a link between his Sharingan and their enemy's, Kakashi questioned Tobi as to where exactly he got the eye from. However, Kakashi is horrified upon hearing Tobi's answer of obtaining his Sharingan from Kannabi Bridge during the previous war. Kakashi is at a loss for words, in a daze thinking of his former comrade, Guy attempts to snap him out of it while Naruto charges at Tobi in his Tailed Beast Mode. After hearing Naruto's speech, Kakashi rallied back and readied a new strategy that requires him to time the few remaining Kamui he can use. Charging forward as Naruto created a shadow clone to attack Tobi, Kakashi seemingly warped away the dispelled clone's Rasengan before collapsing from the strain with his eye bleeding. In reality, however, Kakashi warped Naruto's clone into the other dimension, allowing his student's clone to catch Tobi off guard and shatter his mask.

Kakashi is left completely stunned as he looks on to see that behind the shattered mask, is his childhood friend Obito Uchiha. When Kakashi questions why he never returned to Konoha if he survived, Obito mocks Kakashi by stating his failure to protect Rin was the reason, an answer that only caused Kakashi to sink further in depression and cause Obito to chortle at his expense. After the attack launched by Obito is thwarted by Naruto, they are soon joined by the reincarnated Madara. Shocked by this, they silently watched the Uchiha pair converse amongst themselves, and Kakashi expressed surprise at the fact Madara knew about Obito's Eye of the Moon Plan. While Madara started his confrontation with Naruto and Killer B, Kakashi and Guy prepared to confront their former comrade. Taking advantage of this, Kakashi proceeded to ask Obito why he teamed up with someone like Madara.

Interrupted by the clash between Naruto and Madara, Kakashi again posed the question to Obito. However, his former friend told him that there was nothing more to be said between them, and that the only thing left to do was to have their final fight. Hurling shuriken out of the other dimension, Kakashi blocked Obito's barrage with an earth wall until Obito phased through the wall holding one of the shuriken and stabbed it into Kakashi's left leg. Kakashi's persistence to ask why Obito was doing this only led his former friend to retort that he is trash that does not shut up, and warped Kakashi away to the other dimension. Remembering Obito's words of those who abandon friends being even worse than trash, Kakashi could not believe that the hero he looked up to had forsaken his previous beliefs and used his Kamui to warp himself back from the other world.

Kakashi admits that he is trash for failing to protect Rin as promised, but questions Obito if Rin was related to his new ideals before getting kicked in the face and slashed with Obito's two held shuriken. Calling Obito one of Konoha's heroes while imploring him to not end up like him, Kakashi is told by his former friend that they are both trash because they survived the worthlessness of this reality. Obito prepared to finish Kakashi off before Naruto's shadow clone intercepted Obito's right-hand shuriken, declaring that he would protect his friends with his life. Remembering the exact same words he said to Team 7, Kakashi regained his will to fight and used his Lightning Cutter to destroy Obito's other shuriken. He then proclaimed that he remembered what Obito taught him in the past, and that now he would protect Naruto.

Weakened from his injuries and overusing his Mangeykō Sharingan, Kakashi falls to his knees in exhaustion. Obito again attempts to warp Kakashi to the other dimension, but is stopped by Naruto. After Kurama temporarily switches places with Naruto, it grabs Kakashi, and throws him towards Obito, who successfully warps him away. With no time to complain, Naruto attacks Obito while Kakashi, who Kurama had supplied with chakra when it threw him, attacked Obito's materialised body parts in the other dimension. Warping himself back to the real world, Kakashi looks on as a giant Tailed Beast Ball was fired by B and Naruto at the statue. Kakashi contemplated whether the statue had really been destroyed, but it was later revealed to have successfully become the Ten-Tails.

As Madara and Obito connect themselves to the Ten-Tails by way of tendrils being inserted, Kurama grabs Kakashi and Guy in its mouth to restore their chakra. Kurama, understanding the true nature behind the Ten-Tails, begins giving instructions to how they should face the mighty beast. When Kakashi notes that Kurama is acting like a captain, it thinks Kakashi has a problem with it, but the jōnin merely replies that he actually likes it. Kakashi's kindness to Kurama is shortly enjoyed as the Ten-Tails shows remarkable speed, quickly overwhelming Kakashi and his team. Following Kurama's advice, Kakashi uses Kamui to teleport Gyūki in front of the Ten-Tails, who launches a point-blank Tailed Beast Ball at the resurrected demon.

After deflecting the attack back at Gyūki, the Ten-Tails attempts to attack Naruto and Kakashi with its tail, but Naruto throws Kakashi out of the way in time. Landing in the safety of Kurama, Kurama later dematerialises, and Kakashi falls to the ground. Kakashi finds himself weakened from transporting Gyūki with his Kamui. Stressing the importance of Naruto's life to the war effort, Kakashi finds relief as all divisions of the Allied Shinobi Forces assemble at the battlefield, and Sakura begins to heal him.

Reeling from an attack from a newly evolved Ten-Tails, Kakashi is asked by Shikaku for information regarding his fights with the enemy prior to the Allied Shinobi Forces arrival, but Kakashi is forced to cut contact and attempts to use Kamui against the Ten-Tails. Realising he couldn't use it in time, ordering another to use an Earth Release technique to make the ground underneath the beast uneven, Kakashi is shocked to see the Ten-Tails massive firing distance with a Tailed Beast Ball. Kakashi and Sakura later narrowly avoid one of the wooden stakes that was fired by the Ten-Tails. He later watched on in horror as Neji sacrificed himself to protect Naruto and Hinata from the projectiles, and attempted to chide Obito for degrading Naruto, but was cut off by the former's tirade, in which he pointed out that Kakashi should know that nothing but loneliness was at the end of the path Naruto had chosen to take. He would later affirm that promising to protect loved ones could become a curse, if they were unable to fulfil that promise. Understanding this, Naruto still agreed to keep Neji in his heart and to carry on his will, stating that to do otherwise would be to truly killing Neji.

After receiving chakra from Naruto, resulting in a chakra cloak, Kakashi thought back to his conversation with Shikaku and the feats he was able to accomplish the first time Kurama gave him chakra. He later charged towards, and attacked the Ten-Tails alongside the other empowered members of the Alliance. Ultimately, the Allied Shinobi Forces manage to separate Obito and Madara from the Ten-Tails, which causes the massive demon to start going berserk. As Kakashi prepares to warp it away, he is intercepted by Obito. The two men end up warping to Kamui's dimension but not before Kakashi called out to Naruto, telling him to handle things there.

Upon arriving, Kakashi maintains his balance unlike Obito, allowing him to strike with his Lightning Cutter before Obito could react, only to hesitate and stop at the last moment. While shocked at first, Obito realises that Kakashi is still plagued by guilt and hope for Obito reforming, to which the fallen Uchiha mocks Kakashi for. Kakashi begs Obito to accept that things don't have to be this way, as in many ways the man Obito once was now lives in Naruto. Obito then stood up, phasing through Kakashi's Lightning Cutter. He then revealed that he knew all along the circumstances of Rin dying. That just like how he didn't blame Kakashi for Rin's death, she and Kakashi weren't the reason for him starting this war. Obito tells Kakashi to forget about his guilt as there is nothing left of the man Kakashi once fought alongside, emphasising this from a genjutsu of a gaping hole where his heart should be.

Appealing to Kakashi's happier memories from their childhood, Obito emphasises that the illusion world can give Kakashi back that lost time, creating an illusion of child Obito and Rin, which Kakashi quickly strikes down. Kakashi defiantly refuses Obito's offer of a dream world, saying that illusions will never heal one's pain. While admitting that the real world can be cruel at times, the support of one's friends can ease the pain and rejecting your friends will only add to the pain. Obito scoffed at Kakashi's words, saying that attachments like that are the source of one's pain. Kakashi however reminds Obito of the lesson he once taught Kakashi: One who abandons their friends are worse than trash. As Obito was taken aback by these words, Kakashi declared that he will force these feelings back on Obito, even if he refuses.

Their battle then raged on, with them challenging each other with various genjutsu tactics, constantly ending in a stalemate. Finally deciding to fight for real, Kakashi and Obito as a last sign of respect between former allies performed a challenge salute. The two clashed, almost mirroring a sparring match from their youth. Although Obito managed to pierce Kakashi's right ribs with a black rod, Kakashi impaled Obito through the chest. While Obito laughingly admitted defeat, he told Kakashi he would lose the war before returning to the real world.

Heavily fatigued from his battle against Obito, Kakashi remained in the Kamui dimension to suture his wounds before returning to the battlefield. As he began to catch his breath, he thinks over all that has transpired with the new dark Obito, coming to the conclusion that Obito has not truly relinquished the Will of Fire, but rather pushed it aside and his meeting with Naruto has caused him to gain conflicted emotions. Suddenly, Kakashi begins to see and hear what Obito does through their matching pair of Sharingan. Seeing Obito's continued turmoil, Kakashi notes that Obito could have overcome this hole in his heart if he let his friends fill it with their feelings.

Birth of the Ten-Tails' Jinchūriki
Once recovered, Kakashi teleported back to the battlefield, poised over a defeated Obito. Believing that Obito was his responsibility, Kakashi lunged his kunai at Obito, only for the reincarnated Minato to stop him. While Kakashi was shocked by the appearance of his late sensei, the Fourth Hokage explained that Naruto's persistence has gotten through to Obito. Accepting his inner pain, Obito admits that Rin was the only good thing in his life and losing her only left him in misery. Madara's plan seemed the only sensible choice left in Obito's mind as all he's seen while walking the world confirmed that the world was indeed hopeless. Kakashi admits that he doesn't know for sure if Naruto's views are anymore right and that maybe Madara's isn't completely wrong, shocking Obito. While sympathising with Obito's personal pain of Rin's death along with his other loved ones, Kakashi insists that Naruto's views are at least less likely to fail because his goals naturally draws more people to aid him.

After learning from Minato that Obito would survive, Kakashi prepared to join the battle against Madara. As Kakashi's words fully reached Obito, the Uchiha admitted to understanding why Nagato betrayed him to aid Naruto. Deciding to follow suit, Obito resolved to, as a true act of atonement for his mistakes, sacrifice his life to revive all the fallen shinobi with Outer Path — Samsara of Heavenly Life Technique. Not wanting his childhood friend to die, Kakashi begged him to instead dedicate his life to making amends, to which Obito said would be the "easy" path, no longer feeling worthy to ever see Rin again. Before he could do so, however, Black Zetsu emerged from the ground, merged with Obito and forced him to revive Madara, much to Kakashi and Minato's shock.

Succeeding in his goal, Black Zetsu then proceeded to take Obito's Rinnegan to return it to Madara. Kakashi and Minato quickly acted to stop it, to which Black Zetsu responded by merging again with Obito, warning them that his unison with the dying Obito was the only thing still keeping him alive. Being asked what it is, Black Zetsu responded that he was a manifestation of Madara's will, calling Kakashi and his allies fools for underestimating Madara.

Suddenly, from Obito's artificial body half, the Demonic Statue emerged. Kakashi attempted to stop it by removing the head with Kamui, but the statue is teleported elsewhere, causing Kakashi's attack to instead remove its right arm. As Black Zetsu continued its attempt to take the left Rinnegan from Obito's eye-socket, Obito continued to resist the possession, telling Kakashi to destroy the eye. Looking down on their attempts, Black Zetsu informed them that Madara has already regained his right eye. Obito lost his consciousness.

As Kakashi couldn't feel the presence of Obito being alive, he and Minato prepare to attack Black Zetsu. Suddenly, Gaara appeared with Sakura and a critical-state Naruto, having lost Yang-Kurama to Madara. Gaara quickly told Minato that Naruto can be saved by sealing the Yin half of Kurama inside Naruto. After Minato's attempt to do so was intercepted by Black Zetsu, getting Yin-Kurama sealed inside itself, Madara arrived. Now the Ten-Tails' jinchūriki, Madara seeks to complete his power now in Black Zetsu's possession.

As Black Zetsu attempted to return to Madara and grant the Uchiha Yin-Kurama and the left Rinnegan, Obito managed to overshadow Black Zetsu, keeping it merged to the younger Uchiha. As Obito and Madara began questioning Obito's purpose in life, Kakashi attempted to teleport Obito away from Madara and Minato launches an attack on the Uchiha. Madara easily repels Minato's attack and kicks Minato's Rasengan at Kakashi, forcing Kakashi to warp the Rasengan before it hit him instead. Obito approached Madara impaled Madara's chest with his hand, stating that he is not an extension of Madara, but Obito Uchiha.

Relieved that his friend had regained some sense of himself, Kakashi obliged his request and warped Naruto — along with Sakura — to the other dimension. Standing alongside his comrade, Kakashi conceded to be Obito's backup but noted that the Uchiha better not mess up. As they are both attacked by Madara, Obito and Kakashi both use Kamui in sync allowing Obito to warp to the other dimension before Madara could attack him. With Kakashi left defenceless, however, he was rescued by Might Guy whom Kakashi noted he was actually happy to see for the first time.

As Kakashi and his allies began considering their options against the transcendent Madara, Guy made the first move, attacking Madara with his Daytime Tiger. The attack was easily resisted and Guy was narrowly saved by the timely arrival of Lee. Realising the grim situation, Guy resolved to make his ultimate move, which Kakashi realised to his horror was the suicidal eighth gate. As his friends tried to talk his out of it, Guy expression made it clear to Kakashi that his decision was final. Once accessing all Eight Gates, Guy quickly began to overwhelm Madara.

Realising the limited time Guy had, Minato revealed the true mechanics behind Madara's Truth-Seeking Balls. The group then launched a strategy to support Guy's offence and quickly got rid of most of Madara's only defence from Guy's Evening Elephant. With Kakashi's Sharingan too strained from overuse to properly aim Kamui from a distance, Gaara carried Kakashi on his sand, getting Kakashi close enough to teleport a large portion of Madara's barrier, letting Guy complete his assault on Madara.

As Guy and Madara continued their extreme battle, Kakashi admitted that Guy had indeed surpassed him just as Sakumo predicted years ago. Finally, Guy reached his limit and collapsed, his body thrashed from the effects of the Eight Gates and was quickly dying. Wanting to finish Guy personally, Madara launched his final chakra orb at Guy, only for the revived Naruto to return and deflect it wit his bare foot. With a new look in Naruto's eyes, Naruto then somehow stabilised Guy's life force, sparing the taijutsu master from certain death. As Naruto began to overwhelm Madara with his new-found powers, Kakashi watched in amazement. Realising that he was losing the advantage, Madara absorbed the tree into his being, fully regenerating himself. Sasuke then returned with a similar power to Naruto's and the two joined forces to battle Madara. As the two childhood friends begin holding their own against Madara, the legendary Uchiha decides to focus first on regaining his left Rinnegan. Still exhausted from earlier, Madara catches Kakashi off guard and steals his Sharingan, using it to teleport to the other dimension.

Shortly afterwards, Sakura appeared from the other dimension, revealing that Obito teleported her to safety from Madara. She explained that according to Obito, Madara would become unstoppable with both Rinnegan. After Naruto finished sealing Madara's shadow, he used his new powers to restore Kakashi's original left eye, shocking Kakashi. Watching his three former students bicker with each other, Kakashi reflected on how much they have changed and grown before questioning Sasuke's new goals. As Sasuke remained silent, Kakashi chose not push the question, instead alerting his students of Madara returning and told them to remember the first lesson he taught them: team-work. Upon returning, Madara revealed both his eyes restored and Black Zetsu back in control of Obito, also with both his original eyes. As Zetsu mocked Obito's efforts, the reunited Team 7 prepared to battle, with Kakashi admiring their unison. Kakashi watched on as his former students battled Madara. Finally reaching the full maturity of his new-found power, Madara proceeds to cast the Infinite Tsukuyomi on the world. As people everywhere become assimilated by this technique, Sasuke, with his own Rinnegan making him immune to the genjutsu, uses his Susanoo to shield Kakashi and his allies from the technique.

As everyone asked Sasuke the nature of this technique, Sasuke stubbornly told them to be quiet, insisting that he take care of it. While Naruto was furious at Sasuke's still independent attitude, Kakashi solemnly admitted that with Sasuke's Rinnegan, he may be the only one able to save the world. As the light of Madara's technique subsided, Sasuke let down his Susanoo, noting that only a Rinnegan has a chance of cancelling the Infinite Tsukuyomi. Madara confronted the remaining free individuals, only for Black Zetsu to suddenly betray Madara and impale his hand through Madara's chest, shocking its audience. As Madara asked his own manifestation why he would do this, Black Zetsu boldly stated that it is actually a manifestation of Kaguya Ōtsutsuki. Black Zetsu then proceeded to expand its being into Madara.

As Black Zetsu's influence spread over his creator, chakra began to swirl through the air towards Madara. While Naruto and Sasuke's attempted to destroy their enemies proved futile, Black Zetsu revealed to Kakashi and his team that the captured victims of Infinite Tsukuyomi will slowly be transformed into White Zetsu clones. As the chaos subsided, Madara and Black Zetsu's being were transformed into Kaguya herself. Shocked at this revelation, Kakashi asked the legendary princess about her motives, who stated that the world was her nursery and wanted no more fighting to damage it any further. She then transformed the ground into a river of lava, telling Team 7 that she will have them disappear.

Kaguya Ōtsutsuki Strikes
As Sasuke and Naruto survived the deadly fall on Sasuke's summoned hawk, Kakashi responded quickly to the drop by nailing two kunai in the wall; one stabbing Obito's hand to keep him suspended and the other attached to an unravelled scroll. Kakashi used the scroll as a makeshift rope to save himself and Sakura. Soon after, the lava's intense heat burned through the scroll, resuming Kakashi and Sakura's plummet, but they were saved by Naruto's chakra arms and new-found ability to fly. To keep his full attention on Kaguya, Naruto then used a shadow clone to carry Kakashi and Sakura and retrieve Obito. After Sasuke is captured by Kaguya's dimensional portal, Naruto's clone succeeds in resuscitating Obito. After explaining the situation to Obito, the Uchiha states that using Kamui may be able to work in sync with Kaguya's portal and save Sasuke.

As Kaguya finally notices Kakashi and the others, Kakashi notes that she doesn't even care about them. Once the real Naruto finally forces Kaguya to open her portal, Obito teleports into it with Naruto's clone and Sakura, leaving Kakashi to watch. As Kakashi grows depress in his inability to actively help in the battle, Obito finally returns with Sakura and Sasuke. Kaguya, seeing that the two halves of her son's power have returned, realises she can't hold back anymore. She then enhances the gravity in the area, pinning everyone, including herself, to the ground. She then fires her bone blades at Naruto and Sasuke. Kakashi and Obito quickly rush to protect the younger ninja with their bodies. At the last second however, Obito intervenes. Unable to use more than one Kamui at the moment, Obito takes his hit from Kaguya's attack but protects Kakashi from his projectile, not wanting another friend to die in front of him. As Obito began to crumble, Naruto desperately tried to save Obito again with his Yang power but to no avail. Imparting his final words to Naruto, the Uchiha finally died as he turned into dust. Angered by this, Naruto attacked Kaguya and managed to sever her arm and Black Zetsu with it.

As Naruto bombarded Kaguya with multiple tailed beast chakra-infused attacks, the tailed beasts within Kaguya's body began to react to Naruto, causing the princess to bloat and morph into a massive amalgamation of the tailed beasts with the head of a demonic rabbit. It randomly began launching chakra arms that instantly assimilated whatever it touched. As this happened, the spirit of Obito manifested and entered Kakashi. Inside Kakashi's consciousness, Obito insisted to Kakashi to become the Sixth Hokage. As a parting gift, Obito passes on his chakra, Sharingan powers, and the portion of the Six Paths powers to Kakashi. This allowed the jōnin to manifest both the Mangekyō Sharingan in each of his eyes. With his new power, Kakashi activates his Complete Body — Susanoo to protect Sakura and rejoin the battle directly, shocking his former students with his new abilities. Asserting his presence on the battlefield, Kakashi proceeded to warp away several of Kaguya's chakra arms away. Regaining control of herself, Kaguya then shaped this mass into a giant Truth-Seeking Ball. Acknowledging that his Kamui couldn't stop that, Kakashi devised a plan and shared it with his students, telling them to be ready for what could be their last mission as a team. Quickly enacting this plan, Team 7 were able to coordinate their efforts and penetrate Kaguya's defences to land a decisive blow on her.

From this, Naruto and Sasuke were finally able to place Sage of Six Paths' seal on Kaguya. As the Chibaku Tensei was forming, Madara and the tailed beasts were extracted from Kaguya's form. Ultimately, a new moon was formed and sealed Kaguya and Black Zetsu within it. As Team 7 pondered how to return their own dimension, the spirit of Hagoromo Ōtsutsuki summoned and worked alongside the spirits of all the past Kage to teleport Team 7, the tailed beasts, and Madara to the normal dimension. Kakashi was left shocked at meeting the legendary Sage of Six Paths, who openly commended Kakashi for his leadership of his team. Kakashi humble said the real work came from them. Kakashi then talked with Obito within his subconscious, forgiving his fallen friend for his mistakes and said his final goodbyes, letting Obito return to the afterlife as Kakashi's Sharingan fades from his eyes. After the past Hokage also return to the afterlife, plans for the future are expressed. Much to Kakashi's horror, Sasuke expresses his desire to kill the current Kage and seize control of the tailed beasts, swiftly accomplishing the latter with his Rinnegan. When Kakashi asks Sasuke if he still simply wants revenge, Sasuke explains that what he wants is revolution; to reshape the world as he feels it should have been. As Sasuke turns his attention to his only threat left, Naruto, who firmly says he will finally end the sibling feud. Exhausted from his prolonged use of the Sharingan, Kakashi could only watch as Naruto and Sasuke prepare to do battle. After Sasuke silenced Sakura with genjutsu, he scolded Sasuke for his actions, but was unable to stop him from leaving. Tending to Sakura, he spoke with Hagoromo about Naruto and Sasuke's fate. When Hagoromo starts to disappear, he asks for advice, who tells the former just believe, as there is nothing more they can do.

As Naruto and Sasuke's battle from afar began to ravage the land around them, it began to even effect the area where Kakashi and Sakura waited. Kakashi shielded Sakura from the debris until she finally awoke, to which he explained the situation. Once the carnage final died down, Kakashi and Sakura went to their friends' battleground. There, they found Naruto and Sasuke battered and bleeding out from their missing right and left hand respectively. As Sakura began to heal them, Kakashi thought back again on how their lives became intertwined.

Blank Period
Later, after Naruto and Sasuke dispelled Infinite Tsukuyomi, Tsunade resigned as Hokage and passed the title on to Kakashi. One of Kakashi's acts was to pardon Sasuke of his crimes for his services in ending the war.

Naruto the Movie: Ninja Clash in the Land of Snow
Team 7 was given orders for an A-rank mission to escort the famous actress, Yukie Fujikaze, to the Land of Snow. Upon arriving in the Land of Snow, they were attacked by three Yuki ninjas Kakashi had fought years ago when he was still in Anbu. It was then revealed that Yukie was actually Koyuki Kazahana, the true heir as daimyō to the Land of Snow, who Kakashi saved years ago from her treacherous uncle, Dotō. Kakashi used his Sharingan to copy some of their ice-based technique to escape.

Realising what Dotō was after, Kakashi switched Koyuki's crystal necklace with a fake one, in an attempt to stop him. When Koyuki was kidnapped along with Naruto, Kakashi and the rest of his team mounted a rescue attempt. Soon after Kakashi returned Koyuki's necklace to her, Dotō captured his niece, along with the necklace.

Kakashi was later intercepted by Nadare Rōga. Knowing his opponent had a high protection from ninjutsu and genjutsu, thanks to his armour, Kakashi relied on his taijutsu and defeated him with his Front Lotus. After Dotō was defeated by Naruto and Koyuki took up her role as daimyō, Kakashi learned to his joy that Koyuki would be playing a lead role in a new "Icha-Icha" movie.

After getting assistance from the royal guards, who were still loyal to the king, Kakashi aided their escape.

Later, Kakashi faced off against the leader of the rogue ninja, Ishidate, but failed to keep up with his opponent, thanks to being affected by a special gas, and ultimately having his left arm petrified to stone. This let the rogue ninja capture Michiru. After his arm was cured by Sakura, Kakashi joined a circus as a diversion, while having his team enter the castle to save Michiru. He then used his Sharingan and a water technique to keep the enemies occupied. In the end, Kakashi overused his Sharingan, and was forced to be hospitalised for several days, thus allowing his team to have a vacation in the Land of the Moon.

Naruto Shippūden the Movie
Kakashi only had a few cameos. When word reached Konoha that the legendary demon, Mōryō, had been released, and had begun its quest to control the world, Kakashi was sent out as one of the lead ninja to mount a counter-attack on Mōryō's assault of stone warriors. This was merely to stall for time while Naruto, Sakura, Lee, and Neji Hyūga escorted Priestess Shion, who had the power to reseal Mōryō. Towards the end of the movie, Kakashi appeared with Shikamaru Nara, Might Guy, and Temari to support Naruto and Shion in stopping Mōryō. Here, Kakashi used his Lightning Cutter to destroy several stone warriors. At the end of the movie, Kakashi was shocked by Shion's proposal for Naruto to father her child, which Naruto unknowingly agreed to.

Naruto Shippūden the Movie: Bonds

Naruto Shippūden the Movie: The Will of Fire
When word that all the Great Ninja Nations but Konoha were having wielders of their kekkei genkai abducted, Kakashi and his team were sent to investigate, following the trail of the most recent abducted man to the mountain range of Shumisen. Upon arriving, they are attacked by strange animals that injure Naruto and Sai. After the trail goes cold, Kakashi's team is forced to return to the village. Later, rogue ninja of Konoha named Hiruko appeared and announces to the world via technique that he was responsible for taking the kekkei genkai wielders and assimilated their power with his Chimera Technique to begin the Fourth Great Ninja War. Kakashi, who met Hiruko ten years prior, after obtaining Obito's Sharingan and was branded with a mind-controlling technique in a desire to obtain the Sharingan, realises that Hiruko has not actually gained control of the kekkei genkai he stole and must require certain conditions to obtain them or he wouldn't have waited ten years to go after Kakashi. After theorising that a solar eclipse was one of the conditions, Kakashi decides to face Hiruko. He also asks Tsunade to perform a technique on him. Later, after visiting Obito's grave again, Hiruko's technique takes effect on Kakashi, making him leave the village.

It is later revealed that Kakashi intentionally let this happen, as he had Tsunade implant a seal on him that would activate his Mangekyō Sharingan once Hiruko assimilated Kakashi. Refusing to let Kakashi sacrifice himself, Naruto went after Kakashi and managed to save him. This unfortunately allowed Hiruko a second chance to assimilate Kakashi and his Sharingan before the eclipse ended. Together Kakashi and Naruto fought Hiruko and found an opening for Naruto to unleash his Wind Release: Rasenshuriken to defeat Hiruko. As Hiruko began to die from his injuries, Kakashi went to him. Hiruko asks how he could have failed. Kakashi says that it was because he chose solitude over comrades. Realising that Kakashi made the same mistake in trying to sacrifice himself, Kakashi remembers how Obito once showed him the way and was thankful for Naruto stopping him. The movie ends with Kakashi thinking back on his past when Obito spoke to him about refusing to abandon a comrade and he smiles at Naruto commenting on the similarities between the two. Naruto, however, gains the wrong impression, mistakenly believing that Kakashi was homosexual and making a pass at him, which is commented upon by the rest of the groups present. Kakashi hurriedly denies this and chases after the fleeing Naruto, trying to explain what he meant.

Naruto Shippūden the Movie: The Lost Tower
Twenty years in the past, a young Kakashi is seen in the line of Ramen Ichiraku grand opening, along with Shizune, Asuma Sarutobi and Might Guy, who are impatiently waiting to eat ramen. However, Kakashi claims that they shouldn't be so excited for just ramen. As Shizune replies that he is in the waiting line too, Minato Namikaze appears and tells him to get ready for the mission. Guy asks Kakashi if he's not going to eat the ramen, to which he answers that he doesn't have as much free time as they do and leaves. Shizune calls him a jerk and Asuma agrees with her.

To keep relations between Konoha and the other villages civil, Naruto was arrested and sent to the Hōzuki Castle, which Kakashi explained to be criminal containment facility located in Kusagakure used by all the ninja villages. Despite Naruto's refusal to cooperate, he was quickly restrained.

Later, it was discovered that Naruto was framed to get him sent to the Hōzuki Castle so the council members could use the Nine-Tails' chakra to access the power of Box of Ultimate Bliss. Their goals turned sour when it instead unleashed a horrible demonic creature called Satori. During Naruto's battle against it, Kakashi and Naruto's other allies arrived. Kakashi revealed that they never truly believed Naruto was guilty, but instead pretended so as part of a mission that was a unified effort with Kumogakure designed by Kakashi; they didn't tell Naruto only in fear he would blow his cover. Feeling sorry for hurting Naruto's trust, Kakashi decided he would treat Naruto to as much ramen as he could eat. Despite the Kumo and Konoha-nin's combined effort, Satori was easily able to dodge all of their attacks, as if he could read minds. After Naruto discovered the truth behind the creature's power, Naruto became able to launch an effective counterattack. This allowed Kakashi and the others to round up the escaped prisoners who took advantage of the prison being demolished and their seals removed.

Creation and Conception
Masashi Kishimoto originally intended for Kakashi to début in the second chapter of the Naruto manga, appearing prior to the other members of Team 7. This Kakashi was designed as a laid back, affected, skilled ninja, that ended his sentences with the polite "de gozaru" in the Japanese versions of the series, similar to Kenshin Himura in the popular manga series Rurōni Kenshin and Lance Corporal Dororo in the manga and anime Keroro Gunsou. After speaking with his editor, Kishimoto pushed this début back, allowing him to better develop Kakashi and the rest of Team 7. Despite this, Kakashi retained many of his original personality traits, being easy-going, unfazed by the actions of others, and usually appearing to be half-asleep. Kishimoto felt that this made Kakashi a compelling leader, and helped to keep the diverse members of Team 7 unified. Because he acted as a link between the other main characters of the series, Kakashi was rarely featured prominently in promotional artwork, instead appearing in the background while his students were the focus of the scene.

When deciding upon Kakashi's name, Kishimoto considered a number of possibilities:, , , , and. He eventually decided upon Kakashi, and remained glad that he did ever since. In keeping with the meaning of his name, scarecrows were occasionally used to represent Kakashi; Naruto, for example, used a scarecrow that was dressed like Kakashi to help him train for a combat test between the two. Likewise, scarecrows were sometimes added to sceneries in which Kakashi appeared, as was the case with the cover of the Naruto manga volume three.
