Kakashi Hatake

Kakashi Hatake was a Konohagakure Jonin, and at different times in his life, an ANBU member and the leader of Team 7. He was the son of Konoha's White Fang, Sakumo Hatake, and like him, was a regarded as a genius. After his meteoric rise in the ninja academy, Hataki became the student of the Fourth Hokage, subsequently becoming a Jonin during the Third Great Ninja War. Following the war, Kakashi earned renowned fame for his use of the Sharingan, earning him the moniker Copy Ninja Kakashi.

Early life
Kakashi was the son of the legendary White Fang of Kohona, Sakumo Hatake, and like him was considered a gifted shinobi. He graduated from the academy at the age of 5, becoming a Chunnin a year later. However, his success came at a great loss; his father, once well respected in the village, fell into disgrace after choosing to save his comrades rather than complete a mission, causing Konohagakure to suffer in the war effort. Dishonored, Sakumo committed seppuku after deep depression and a drop in his skills, which caused Kakashi to lead his life strictly by the Ninja code. His White Light Chakra Saber, for which his father was nicknamed, was given to Kakashi.

Kakashi Gaiden
He went on to become apart of the future Fourth Hokage’s team, alongside Obito Uchiha and Rin, a medic-nin. Kakashi's relationship with Obito and Rin was very much similar to that of Sasuke's relationship with Naruto and Sakura respectively in which they share a complicated relationship that later developed into a close friendship.

In the midst of the Third Great Shinobi War, at a meeting to hear their new mission, Kakashi is elevated to Jonin and receives gifts from his sensei and teammate; a special kunai from the Fourth and a medical pack from Rin. After receiving their gifts, the Fourth informs the team of their mission: they must travel through the Grass Country in the midst of a conflict between Iwagakure and Konohagakure to destroy a bridge. Along the way, Kakashi’s team notices that they’re being watched from the trees by Mahiru, an Iwagakure ninja. Kakashi sees this as a good opportunity to use his newly created jutsu, the Chidori. He arrogantly ran off to attack the hidden foe, only to face off against Mahiri’s multiple Shadow Clones while Rin was captured by enemy Shinobi. Obito immediately stated his intention to rescue her, but Kakashi disagreed on the basis that they needed to complete their mission, opting not make the same mistake his father did. Kakashi parted ways with Obito soon after, and as he reflected on Obito’s words and Rin’s prior kindness, he realized that his father had made the right choice after all. This prompted him to rejoin Obito in the rescue effort, claiming that Obito couldn’t survive on his own.

During the attempt to rescue Rin, Kakashi detected a Rock ninja, and yelled a warning to Obito, who was too slow to react. Kakashi jumped in front of Obito to save him from the enemy's kunai. losing his left eye in the attack. Obito, in return, awakened his Sharingan and killed their assailant. The two managed to rescue Rin, however, a rockfall technique was triggered, hindering their escape. It was then that Obito chose to make the ultimate sacrifice, pushing Kakashi out of its path. As he laid there dying, Obito had Rin implant his Sharingan eye in Kakashi’s damaged eye socket, referring to it as a gift. He died shortly thereafter. As his first act with his new eye, Kakashi avenged Obito by killing the enemy ninja with his now-perfected Chidori technique.

Obito's death had a huge impact on Kakashi's personality; initially flaky and unreliable, Kakashi became more mellow, having adopted some of Obito's traits such as his notion for teamwork.

Joining the ANBU
Prior to the Fourth Hokage’s death, Hataki joined the Konohogakure ANBU where he served as squad leader. During this time, Kakashi rose to fame as Konohagakure's Copy Ninja, a nickname he earned due to use of his Sharingan eye- having copied over a thousand jutsu. He cultivated a group of students- which included Yugao Uzuki and Tenzo, and recognized the latter as the most successful of this group. It is unknown when or why he left ANBU, but he is never seen without the iron guards on his gloves, a characteristic of ANBU uniforms.

Kakashi and Team 7
Amongst the students and instructors at the academy, Kakashi developed a reputation for failing every potential Genin team that took the Survival Training Exam he proctored. When he was given Team 7, Naruto Uzumaki, Sakura Haruno, and Sasuke Uchiha he gave them a Survival Training Test to retrieve two bells off Kakashi. Only members with a bell would be allowed to eat, and there was no sharing with odd man out. However due to Sakura's tunnel vision focus on Sasuke, Naruto's impulsive insistence on being a one man show and Sasuke's arrogant superiority complex and loner attitude resulted in a huge lack of teamwork, which led them to fail the Survival Training Exam. Only after he left when Sakura and Sasuke tried to feed Naruto after he failed did he reveal the purpose of the test; not to follow rules that would jeopardize the lives of their comrades.

Personality
Obito's death profoundly changed Kakashi, and Kakashi adopted many of Obito's traits. One such trait was Obito's concept of teamwork, which is most clearly seen in the way Kakashi tests newly-graduated students hoping to become a squad under him. He uses the bell test to test his students, which requires the three students to get the two bells he keeps on his person. Only those who get a bell get to pass, which would be difficult even with teamwork, as at least one ninja would fail regardless. However, the rule is only a ruse; the point of the test is to foster teamwork and to teach the students that teamwork is more important than the rules. Team 7 is the only team to realize this, and as such becomes the only team Kakashi passes into Genin-status. Kakashi also inherits Obito's chronic tardiness, due primarily to losing track of time during his frequent visits to Konoha's memorial site, where Obito's name is engraved. Ironically, this very habit is one that Kakashi was often annoyed at Obito about. Obito was supposedly late due to random good deeds.

Despite this, some of Kakashi's old characteristics remain. Unlike many other ninja from Konoha, Kakashi almost never shows any emotion. He also tends to say things rather bluntly as he suggested that Rock Lee brought the injuries he recieved from Gaara on himself for using Forbidden Taijutsu. He also isn't willing to allow anyone to get truely close to him as he already said everyone close to him is already dead.

Kakashi's personal life is almost non-existent. Aside from his life as a Konoha shinobi, any personal aspects of his life are a mystery. Even his face is a mystery to most of the village, as when Team 7 tried to get him to remove the mask, he wore a lighter colored mask under it. Kakashi has also found himself in a one-sided fued with Might Guy with Guy constantly proclaiming that Kakashi is his rival, and considering his and Kakashi's subordinates rivals. Kakashi, however, seems indifferent to their rivalry, which annoys Guy to no end. Guy randomly challenges Kakashi to contests of skill, and Kakashi has acquired a record of 49 wins and 50 losses in doing so. Given that the contests that make up this figure are so varied (ranging from Rock, Paper, Scissors to sumo-wrestling), this is not much of an achievement on Guy's part. Nevertheless, Guy is proud of his record.

Though he states he has many hobbies, the only one actually seen his his reading of Jiraiya's adult or pornographic Icha Icha series a During the first bell test, Kakashi was reading cha Icha Paradise" (イチャイチャパラダイス Icha Icha Paradaisu?, literally "Make Out Paradise"). Later he is seen reading Icha Icha Violence" (イチャイチャバイオレンス Icha Icha Baiorensu?, literally "Make Out Violence"). Finnally in Part II Naruto gave him "Icha Icha Tactics" (イチャイチャタクティクス Icha Icha Takutikusu?, literally "Make Out Tactics"). Tactics end up being his downfall during the second bell test with Naruto and Sakura as the two came rushing at him with Naruto about to reveal spoilers causing Kakashi to cover his ears so he could hear them speak, thus ruining his ability to hear their jutsus, and closing his eyes so his Sharringan eye could read their lips.

Abilities and Jutsu
When Kakashi was younger, he was taught the Rasengan by the Fourth. However because the Rasengan was ment for the users chakra element mixed with the attack, Kakashi had to abandon it because he was unable to do so with this lighting element. Instead Kakashi produced his only original technique, the Chidori. However the attack has many two main drawbacks for him. The first is the speed of the attack, and the fact that the user has to run in a straight line. Combining the two creates a tunnel effect for the user meaning one simply has to move out of Kakashi's field of vision to avoid it, though this fault was nullifed with the use of the Sharingan. The second is the amount of chakra needed for the attack; the Chidori uses so much chakra that one can only use it a few times a day, with Kakashi's limit being four. Kakashi has since created a stronger, more focused version of the Chidori called the Raikiri (雷切, literally "Lightning Blade). Though it is stronger than a standard Chidori, Kakashi still can only use it four times a day.

However after his first mission as a Jonin and with the death of Obito, Kakashi gained his Sharingan eye. With the Sharingan Kakashi can copy any move his opponent can do and use it against him which gave him the name The Copy Cat Ninja. The drawback is that because Kakashi has no Uchiha blood, the Sharingan eye is always active and thus would constantly use chakra if it was allowed to see, and uses much more chakra than it would for an actual Uchiha. Despite this, Kakashi's control over the eye is as good as Itachi Uchiha though the latter's eye is stronger. By Part II Kakashi developed his own Mangekyo Sharingan, which is able to manipulate space-time for long range attacks. He has been shown to be able to tear off ones limbs and send those limbs to another dimension. However, probably because of his lack of Uchiha blood, his Mangekyo Sharingan takes alot of chakra and energy, after using it three times Kakashi was hospitalized for a week.

WIth the power of his Sharingan, Kakashi is able to copy many ninjutsu not of his element such as Fire Release: Great Fireball Jutsu, Water Release: Water Encampment Wall to block attacks, and Earth Release: Inner Decapitation Technique to immobilze them by dragging them into the ground. He can also use the Shadow Clone technique but because he lacks Naruto's Chakra reserve he uses the ability with caution. Other than these mentioned, Kakashi has a slew of other techniques such as the Summoning Technique where he summons Ninja Dogs, and unpar with Might Guy when it comes to taijutsu.
