Itachi Uchiha

was an S-rank missing-nin from Konohagakure's Uchiha clan and a prominent member of Akatsuki who was partnered with Kisame Hoshigaki.

Background
Itachi was born into the Uchiha clan to Mikoto and Fugaku and was praised by all as the best of his generation; a genius above all others. Even by the standards of the battle-adept Uchiha clan, Itachi's prowess far outshone them. However, not even his family, friends, or teachers could understand him. When he was only four, Itachi had already witnessed countless lives lost due to the Third Shinobi World War, which emotionally traumatised him and turned him into a pacifist.

During the Nine-Tails' attack on Konoha, Itachi held his infant brother Sasuke and told him that he would protect him no matter what as well as wondering where his parents had gone.

At age 7, he graduated from the Ninja Academy at the top of his class after only one year, mastered the Sharingan at age eight, passed the Chūnin Exams at age 10, and became an ANBU Captain at age 13.

He was praised highly by his father, who saw the family's future in Itachi and hence inadvertently neglected his younger son. However, during this time Itachi showed great affection towards his little brother and even encouraged his father to come to the Academy enrolment ceremony for Sasuke, something their father had otherwise forgotten, by saying that he would not go to an important mission that would establish Itachi a place in the ANBU ranks, otherwise.

When the Uchiha clan began planning to overthrow Konoha, Itachi, as an ANBU, was tasked with spying on the village. Knowing that a coup d'état would only lead to another Ninja War; Itachi began spying on the Uchiha instead, passing on information to the Third Hokage and the other Konoha elders. During this time he began to act strangely, not attending the clan meetings, speaking out against the clan and becoming the prime suspect for the murder of his best friend Shisui Uchiha, who was drowned in the Naka River. In reality, Shisui had entrusted his remaining Mangekyō Sharingan to Itachi, the other having been taken by Danzō. Itachi assisted Shisui in making it seem that his eyes were destroyed. Due to this the clan lost hope in Itachi, and his father began shifting his focus to Sasuke instead. Meanwhile, the Third's attempts to negotiate a bloodless end to hostilities between the two parties were proving ineffective so, against the Third's wishes, Danzō Shimura and the Konoha Council ordered Itachi to wipe out the Uchiha clan.

Before the fateful night arrived, Itachi discovered the existence of Madara Uchiha, who was attempting to rekindle the flames of war in Konoha. In return for not attacking Konoha, Itachi offered to help Madara claim vengeance against the Uchiha for turning their backs on him decades earlier; Madara agreed. Itachi slaughtered his entire clan overnight, sparing only Sasuke, because he could not follow through with the orders to kill him. Instead, he made himself out as a villain, who had killed their innocent family only to test his abilities. He told Sasuke that he was not even worth killing. In addition, Itachi told him, "You've always wanted to surpass me. That's why I'm going to let you live… if you wish to kill me, then hate me, despise me… and by all means flee, cling to your wretched life". Itachi also revealed to Sasuke where the secret meeting place of the Uchiha was hidden, and suggested that Sasuke go there to learn what the true history and purpose of the Sharingan was. He told him that "to awaken the Mangekyō Sharingan", he "had to kill the person he was closest to", and that "when we battle, we should have the same eyes".

Sasuke managed to stand back up, awaken his Sharingan, and pursue Itachi. Upon reaching Itachi, he managed to knock off his forehead protector. Itachi shed a tear as he was picking up his forehead protector. He then proceeded to incapacitate Sasuke, who awoke in the hospital remembering only that which Itachi wanted him to. By doing all this, he wanted Sasuke to take vengeance on him and become a hero to Konoha, thus redeeming the Uchiha name. Hoping that his beloved little brother would someday be powerful enough to kill him, Itachi left the village as a traitor. According to Madara Uchiha, Itachi also had a lover, whom he killed during the Uchiha clan massacre.

Knowing that Konoha would still want to eliminate Sasuke, Itachi pleaded with the Third Hokage to keep Sasuke safe. He also threatened Danzō to not harm Sasuke or risk Itachi revealing everything he knew about Konoha's secrets to enemy countries. Sasuke's safety was therefore secured and Itachi returned to his original plan of becoming infamous for his slaughter of the Uchiha clan.

Itachi joined Akatsuki in order to keep an eye on the organisation, along with Madara Uchiha, in case either ever acted against Konoha, all the while planning for his death at Sasuke's hands. While he was a member of Akatsuki, Itachi was approached by Orochimaru, who tried to steal his body to gain the Sharingan. Itachi trapped him in a genjutsu and severed his left hand as punishment, forcing Orochimaru to flee the organisation. He was partnered with Kisame Hoshigaki, who he initially greeted with threats after the latter tried to intimidate him. However, they eventually became good partners for sharing the common bond of having betrayed the people closest to them. Sometime after joining Akatsuki and forcing Orochimaru to flee, Itachi helped recruit Deidara by beating him in battle using only genjutsu, to which Deidara swore vengeance against Itachi.

At some point in time, Itachi contracted a fatal illness. He kept himself alive through the intake of various medicines and sheer "willpower", in the hopes of living long enough to die by Sasuke's hands.

Personality
Ever since his first appearance, Itachi had always been mysterious and acted as though he were hiding his true self. While flashbacks to his past showed that he was a compassionate brother and person, his later acts and claims made it seem that this was mostly just an act. But surprisingly, he genuinely was the compassionate brother he had once claimed to be, although he hid this from the rest of the Akatsuki to protect Sasuke.

As a member of Akatsuki, he possessed incredible self-control of his emotions, constantly displaying an emotionless personality. He only showed surprise when opponents proved more powerful or skilled than he had expected, and even then he didn't lose his composure. He did not possess any arrogance, and fully justified any statements he made about his power, even complimenting his opponents at times on their abilities. After his death, he realises that he shouldn't have tried to deal with Sasuke on his own and encourages Naruto to never forget his friends.

In addition to being an extremely powerful shinobi, Itachi had equally impressive intelligence, and was shown to be very wise, something even Madara acknowledged. He was exceedingly sharp and observant to any situation at hand, as he was rarely surprised or caught off guard. He also displayed great intuition, as he was almost never deceived and even then almost instantly realised the truth. This intelligence could also be seen through Itachi's immense foresight, such as examples like the foreknowledge of Sasuke's defeat of Deidara and simultaneous survival, his own pre-meditated fatalist view of death by Sasuke's hand, and most recently the implantation of his own Kotoamatsukami-imbued crow inside Naruto were only some examples seen. Despite his status as a wanted criminal, and having wiped out his clan, Itachi took no enjoyment in violence or combat, instead preferring to avoid battle or, if this was not possible, end it as quickly as he could.

Itachi's only initial interest was in Akatsuki's goals, and his only loyalties appeared to be to the organisation and its members, seeming to put the organisation's success and secrecy before everything else. As such, Itachi got along with his partner, Kisame, much better than most other Akatsuki members did with their own partners. Kisame appeared to have a deep loyalty to Itachi, immediately doing as he instructed and constantly looking out for his well-being. Itachi treated all of his fellow Akatsuki members to this same, more respectful personality, although his courtesy was rarely returned by the other members.

However, when he was in a genjutsu duel during his fight with Sasuke, he cruelly claimed he had only let Sasuke live so that he could take Sasuke's eyes and obtain his own Eternal Mangekyō Sharingan, after which he then claimed the Uchiha clan had been nothing but tainted and evil, since many members would kill their friends to gain the Mangekyō Sharingan, and would take another Uchiha's eyes to make its power permanent. Once the genjutsu was released, he called it his true self, implying his calm, emotionless personality was also a façade. This persona was later revealed to be only an act to ensure that he would die by Sasuke's hands, his love for his younger brother being the fundamental aspect of his personality.

In the end, Itachi put all of his faith in Naruto, who he notes as the person most determined to save and protect Sasuke. After hearing Naruto's answer to keep protecting Sasuke and everyone in Konoha, Itachi gave him some of his power. He was very grateful towards Naruto's determination to save Sasuke, and was smiling after hearing Naruto's response. Itachi even trusted him enough to bring Sasuke back to the light and refused to go see his brother after being resurrected by Kabuto, as he believes that Naruto, who has inherited Shisui's feelings, can stop Sasuke.

Appearance
Despite his status as an infamous shinobi, his appearance was not the most intimidating, apart from the intensity of his gaze. While living in Konoha, he would regularly have a gentle and caring look in his eyes, especially directed towards his younger brother. After joining Akatsuki, he would regularly have a stern look to them.

Itachi had dark eyes, black hair that hung near his cheeks (which grew slightly longer in Part II) to frame his face and kept the rest of it in a ponytail; which was later obscured by the high collar of the Akatsuki cloak he wore after joining the organisation. Being brothers, Itachi and Sasuke had a similar appearance but with subtle differences, so much so that Naruto nearly mistook Itachi for Sasuke when they first met. In comparison to his brother, Itachi's hair colour was slightly duller and had a softer flow to it; his skin was also slightly darker. Itachi's most distinguishing characteristics were the long pronounced tear troughs under his eyes; a physical trait he inherited from his father.

When he lived in Konoha, his casual clothes would consist of a black Uchiha shirt with a large Uchiha clan symbol on the back, and black pants with a weapons pouch strapped to his back. When on duty, he would wear the traditional ANBU uniform, although he was never shown wearing a mask. As a member of Akatsuki he wore the traditional Akatsuki cloak and usually kept the centre of it buttoned down, as well as a slashed Konoha forehead protector. At other times, he would unbutton the top half of his cloak and rest his left arm there, rather than in the sleeve. After his cloak was incinerated by Sasuke's Kirin during their fight in Part II, it was revealed that he wore similar clothes to that of the rest of the Akatsuki underneath it consisting of a blue v-neck T-shirt (where as most other Akatsuki members wore a sleeveless shirt) and blue pants with a body mesh under the T-shirt, and a white sash around his waist on the outside of the shirt much like a tunic. Like almost all members of Akatsuki, he wore the headband of his home village with a horizontal line gouged through it to symbolise his broken ties with the village. On his right ring finger was his Akatsuki ring, which was red in colour and bears the kanji for. He also wore dark purple nail polish on his fingers and toes and a necklace with three metal circles or rings on it.

After being resurrected, Itachi's eyes appeared to have black sclera like the other shinobi that Kabuto Yakushi resurrected, except for his activated Sharingan. He was also clad in a dark-red cloak.

Abilities
Even at a young age, Itachi's intellect and talent showed their brilliance in everything he did, as even his teachers said his progress hardly required any help. In the few battles he had been seen in since the start of the series, Itachi was shown to be an incredibly powerful ninja, as demonstrated by his ability to easily defeat several powerful shinobi. Despite his pride in his own strength, Kisame Hoshigaki, Itachi's partner in Akatsuki, acknowledged Itachi as the stronger of the two. Madara said that Itachi never ceased to amaze him, and Kabuto recognised that he had underestimated his intelligence, after he managed to break free of his control through the use of Shisui's dōjutsu. However, despite his abilities, he was aware of his limitations, given his praise of Jiraiya, saying the best he could do against him was a stalemate. The only thing that Itachi was lacking was his chakra reserves, which were below average, presumably made worse due to his illness. Regardless, even with his fatal illness and his own preplanned death as inhibitions, Sasuke was still unable to defeat Itachi, who instead succumbed to his disease and the strain of maintaining his Susanoo on such low chakra. Despite the stress his body was under that was slowly killing him he was still able, in his last moments, to perform his own fūinjutsu.

Being a technical pacifist due to his traumatic experiences from the Third Shinobi World War, Itachi did not actively take part in battle, typically only acting in self-defence and trying to incapacitate his enemies instead of killing them if possible.

Taijutsu
Itachi possessed very high-level taijutsu skills despite not specialising in it. This was demonstrated when he easily dispatched three fellow Uchiha, all of them his seniors as well as members of the Konoha Military Police Force. In Part I, he stopped Sasuke's Chidori with one hand and brutally beat him during their reunion in the Land of Fire despite Sasuke's extensive taijutsu training for the Chūnin Exams. In Part II, despite his illness, Itachi was able to once again outmatch Sasuke who had improved his taijutsu under Orochimaru's tutelage.

Itachi was also noted to be immensely fast, particularly with his hand movements. This extended to collectively weaving both hand seals and throwing weapons, as he was able to reveal a set of shuriken and then suddenly perform a ninjutsu, making it appear as if he could perform his techniques without seals. In terms of mobility, he is able to cover considerable distances fast enough to appear like teleportation. His speed was such that neither Sasuke nor Kakashi, who are both very fast and adept at using the Sharingan, could follow his movements in either case during Part I. He could also evade consecutive strikes from Killer B's unusual kenjutsu without injury, despite B's style being acclaimed for its difficulty to both read and dodge successfully.

Ninjutsu
Itachi was a master of all the Uchiha clan's techniques, along with the Sharingan, and had great prowess with all of the three main types of jutsu. When battling against Kakashi, Kurenai, and Asuma, Kakashi commented that Itachi wasn't fighting with even half of his strength. Itachi's techniques also often involved usage of crows, both in ninjutsu and genjutsu. This is seen amongst others with his creation of a clone that dissolves into crows and using crows to hide shuriken in them or creating shadow clones with the ability to explode.

As traditional to the Uchiha clan, Itachi could use Fire Release techniques including the clan's Fire Release: Great Fireball Technique and was able to infuse shurikens with fire. The heat of his Great Fireball Technique is great enough to bother even Samehada. He was also shown to use Water Release techniques such as creating a drilling mass of pressurised water.

Itachi's skill with kunai was such that he could perfectly hit a set of nine targets, one of which was in a blindspot hidden behind a large rock by hitting one kunai with another making it hit the target; he was able to combat Sasuke's masterful swordsmanship with a kunai. During his fight with Nagato, he was able to find blindspots and blind the latter's summons despite the shared field of vision granted by the Rinnegan. He was also very skilled with shuriken, Sasuke stated that he was best with shuriken, even more skilled than their father. During their fight at the Uchiha Hideout, Itachi was able to counter every one of Sasuke's shuriken with his own. After being revived, Itachi was also able to blind Nagato's Giant Snake-Tailed Chameleon and the King of Hell attacking them with shuriken from their blind spots, an ability that Kabuto cursed.

Sharingan
Being of the Uchiha clan, and as noted by Kakashi, Itachi was a true successor of the Sharingan, having fully developed and mastering it by the time he was eight years old. From a stationary position, he would study an opponent's movements with his Sharingan and respond accordingly, often with a genjutsu. Itachi was often praised for his prowess with genjutsu and could cast it by merely pointing at or looking at someone, and could similarly turn an opponent's genjutsu against them with Demonic Illusion: Mirror Heaven and Earth Change. According to Ao, he could also use his genjutsu to take control of other individuals from a long distance. Most of his genjutsu are derived from the Sharingan, but regardless of whether they are or not, all of them cause powerful mental trauma.

Using his Sharingan, he could also perfectly fake Shisui Uchiha's suicide letter after he had supposedly killed him. He had trained so much with his eyes that he had reached the stage where he could have his Sharingan activated for extended periods of time, with minimal drain on his chakra levels.

Mangekyō Sharingan
Itachi possessed the Mangekyō Sharingan, which increased his already great power, and enabled him to use his most powerful techniques. With his left eye, he could use Tsukuyomi, a genjutsu that traps an opponent's mind in an illusory world, torturing them for what seems like days to the victim, in a matter of seconds. With his right eye he could use Amaterasu, a ninjutsu which allowed him to create a black flame, that he could direct by moving his eye, to burn through anything in its path, including fire itself. His final technique was Susanoo, the, a technique that uses both eyes to manifest itself as a spectral being. It wielded the Sword of Totsuka, an ethereal sword with the ability to seal anything it pierces into the gourd that serves as its hilt, and Yata Mirror, a shield that could reflect any attack. Zetsu, a fellow Akatsuki member, stated that Itachi's mastery of the Sharingan, combined with the legendary weapons of Susanoo, made him nearly invincible. With Susanoo he was also able to use his most powerful long-ranged attack, the Yasaka Magatama.

Despite his mastery of the Mangekyō Sharingan, Itachi suffered greatly from its side effects. Each of the techniques bestowed by the Mangekyō Sharingan required vast amounts of chakra to perform, and they left Itachi fatigued afterwards, to the point of requiring him to deactivate his Sharingan altogether, something that he did not usually need, three uses of which seem to have been enough to bring him to this in Part I. The other side effect was that his eyesight would worsen as time passed since the awakening of the Mangekyō Sharingan, and the degradation would only increase after every time he used it, which would lead him to eventually go blind from its power, with his Sharingan forever sealed away. By the time Itachi activated his Mangekyō Sharingan during his final fight with Sasuke, Itachi's eyesight was so badly damaged, that Sasuke appeared to be only a messy blur and was so close to blindness that by the time he activated Susanoo in his final fight, both Sharingan had lost the Mangekyō design in them, with only the red iris remaining.

Search for Tsunade Arc
After the Invasion of Konoha and the death of the Third Hokage, Itachi and Kisame infiltrated the Konoha to find Naruto Uzumaki, the container of the Nine-Tailed Demon Fox. Before searching for Naruto, the two quickly stopped for tea after a suggestion from Kisame. While there, however, their uncommon clothes drew the attention of Kakashi Hatake, who had Asuma Sarutobi and Kurenai Yūhi follow them. Itachi and Kisame nearly managed to escape the village, before Asuma and Kurenai managed to catch up with them in time.

When the two revealed their identities, Itachi and Kisame were quick to battle Asuma and Kurenai after they refused to leave. Despite their high ranks of jōnin, Asuma and Kurenai stood little chance against the two Akatsuki members. However, the arrival of Kakashi managed to keep Asuma and Kurenai from receiving any major injuries. After a short skirmish with Kakashi, Itachi activated his Mangekyō Sharingan and used Tsukuyomi to attack Kakashi's mind and spirit, which afterwards left the latter confined to bed for several days. After Kakashi revealed he had knowledge of Akatsuki, Itachi ordered Kisame to kidnap Kakashi and to kill Asuma and Kurenai. However, Might Guy then showed up, revealing that he had already told the ANBU about the two Akatsuki members' presence. Itachi and Kisame retreated, saying that they didn't want to start a war.

Itachi and Kisame tracked Naruto to a hotel where he was staying with Jiraiya at the time. Uninterested in provoking a Sannin, Itachi used a genjutsu on a pretty woman to draw Jiraiya away from Naruto. Taking the chance, Itachi and Kisame confronted Naruto, although, at the very same moment, Sasuke arrived to seek vengeance on his brother. Itachi handled his brother with ease while Kisame and Naruto watched, although Jiraiya arrived in time to save the two boys, having not fallen for the hypnotised woman's charm as he knew that pretty women did not usually show interest in him.

Jiraiya immediately asked Itachi and Kisame if their real goal was kidnapping Naruto. They confirmed this and Itachi understood that Jiraiya was the one who had told Kakashi about Akatsuki. Although Jiraiya wished to fight them himself and prevent others from getting hurt, he honoured Sasuke's feelings, and allowed him to fight Itachi instead. Itachi, however, only proved Jiraiya wrong in letting Sasuke fight by using his Mangekyō Sharingan on his younger brother, thus reaffirming his need to get stronger. Jiraiya saved Sasuke in time by using the Summoning: Toad Mouth Bind, which transformed the entire hotel hallway into a toad's oesophagus to trap Itachi and Kisame. Despite Jiraiya's claim that no-one had escaped this technique before, the two Akatsuki partners managed to evade capture and death using Itachi's Amaterasu, which left him exhausted.

Although he was actually supposed to capture Naruto, Itachi's only reason for returning to Konoha after the death of the Third Hokage was to remind Danzō and the other two village elders that he was still alive and not to harm his younger brother.

Kazekage Rescue Arc
While Akatsuki was sealing the One-Tailed Shukaku, they discovered that Team 7 and Chiyo were en-route to their location. Itachi volunteered to distract them, so Pain used the Shapeshifting Technique on Yūra to create a body-double for Itachi. The lookalike, under Itachi's control, engaged the Konoha ninja. He was impressed by Naruto and Kakashi's improvements in strength but, because the clone had only a portion of his ordinary strength, it was killed by Naruto's Big Ball Rasengan. Nevertheless, he was able to buy enough time.

Itachi Pursuit Arc
As Sasuke was defeating Orochimaru, Itachi sensed something odd. Kisame asked him what was wrong, to which Itachi replied, "No, it's nothing." Following Kisame's capture of the Four-Tails, Itachi and Kisame met with the rest of Akatsuki. There, they discovered that Sasuke, after being trained by Orochimaru for two and a half years, had killed his teacher. Sometime after the Four Tails was sealed, Zetsu informed them that Sasuke had been killed by Deidara's C0. Kisame asked Itachi if he was upset that Sasuke's death had left him as the only Uchiha because in the rain he looked as if he were crying. However, Itachi remarked that Sasuke was not dead, and alluded to the fact that there was still another Uchiha regardless.

Knowing that his end was near, one of Itachi's shadow clones confronted Naruto, who was looking for Sasuke. Although he claimed he wished only to talk, Itachi was forced to defend himself against Naruto's attacks. After fending off Naruto, Itachi asked why he showed so much interest in Sasuke, a traitor to Konoha. Naruto replied that he was more of a brother to Sasuke than Itachi had ever been, and that he would do whatever it took to bring Sasuke home. This caused Itachi to give a small smile, followed up by asking if he would always feel that way, even if Sasuke attacked Konoha. Naruto replied only that, if that happened, he would stop Sasuke without killing him and protect the village. Content with this answer, Itachi gave some of his power to Naruto, by forcing him to swallow one of his crows, and hoped he would never have to use it.

After his business with Naruto was done, another of Itachi's shadow clones went to meet with Sasuke. Sasuke exhibited a dramatic improvement in his abilities during their confrontation, so Itachi agreed to have their final battle at the Uchiha Hideout. He waited there for Sasuke's arrival, instructing Kisame to not let the other members of Sasuke's team interfere with their combat. Itachi and Sasuke met face-to-face and, while exchanging genjutsu, had a conversation about the Uchiha, Madara, and Itachi's "true" motives of wanting to take Sasuke's eyes. When Sasuke managed to escape Itachi's Tsukuyomi, the genjutsu battle ended and the ninjutsu battle began.

Itachi used Amaterasu, but Sasuke protected himself by shedding his skin, a technique he was able to use due to Orochimaru being sealed within him. Using the shed skin as a decoy, Sasuke went below and fired a Fire Release: Great Dragon Fire Technique at Itachi's direction above although he only managed to burn away one of Itachi's sleeves. Out of chakra, he told Itachi about his final jutsu that, like Amaterasu, is impossible to avoid. Sasuke then used his trump card, on Itachi, who got his Akatsuki cloak burned off as a result.

However, Itachi managed to survive by using Susanoo to defend himself. With Kirin having expended all of Sasuke's chakra, Orochimaru was able to assume control and violently appeared through his Eight Branches Technique. However, Itachi was easily able to cut off the seven snake heads, leaving only one behind whose mouth Orochimaru appeared out of and thanked Itachi for pushing Sasuke so far, in the process setting him free and allowing him to take control of Sasuke's body. Itachi, however, stabbed Orochimaru with the Totsuka sword to seal him away with Susanoo, thereby removing the cursed seal from Sasuke's body.

As Itachi began to weaken, thus weakening Susanoo, Sasuke saw an opportunity to strike, but in vain, as Susanoo was still able to protect Itachi. His last option gone, Sasuke was pushed against a wall and left helpless as Itachi walked up close to him and seemed to be reaching for Sasuke's eyes. However, he instead poked Sasuke's forehead and smiled before saying, "Forgive me Sasuke… …It ends with this."; this was a reference to Itachi constantly poking Sasuke on the head when they were younger. With that act, Itachi finally gave in to his fatal illness, which he had been using medication and sheer willpower to fend off, and died.

Konoha History Arc
In the anime, three years ago before Sasuke's defection from Konoha, Nekobaa mentioned about Itachi, but was stopped by Sasuke from talking about him. After Sasuke defeated Nekomata, he told Sasuke that Itachi had defeated him in the past along with his ninja cats and requested that he fight Sasuke with all his might when he got older.

Later, Sadai, an assailant who entered the Land of Fire to capture Naho, mentioned to Sasuke about Itachi, the Uchiha Clan Massacre, and even about Sasuke for being weak, which led to Sasuke defeat Sadai and punch him severely.

Confining the Jinchūriki Arc
Itachi was summoned by Kabuto Yakushi through the Summoning: Impure World Resurrection, along with Nagato, Kakuzu, Sasori, and Deidara as a demonstration of power to Madara.

Shinobi World War Arc
Itachi was summoned along with many other powerful ninja as Madara and Kabuto head out for war. When given orders to set out, he moved in the same direction as Kakuzu, with the latter carrying Nagato on his back.

Under the cover of night, Itachi supports Nagato as they walk through a forest. The two have a conversation about Akatsuki and what their summoner had in store for them. Nagato noted how they were both being used due to their powerful dōjutsu. Itachi then comments that their summoner is likely intending to use his genjutsu abilities once the time is right. Nagato remarks that Itachi was truly a shinobi shrouded in darkness. After stopping at a shrine, they continue to discuss Madara's plan and his strategy. As Itachi and Nagato walk through the woods approaching some mountains, they encounter Naruto and Killer B.

Surprised by Naruto's growth and subjugation of the Nine-Tails, Itachi tells Naruto that he has something to ask him, but before he can he is forced to attack the two men with the Fire Release: Great Fireball Technique and then directly with taijutsu. As Itachi attacks, he asks him what happened to Sasuke, becoming visibly surprised and disappointed by his brother's decision to destroy Konoha and realising that Madara knew the truth behind the event all along. Itachi asks Naruto not to tell anyone else about the truth behind the Uchiha clan massacre as he wanted his clan's name to maintain its honour, entrusts Sasuke to Naruto and states that he was glad that he placed his trust in Naruto. As Itachi faces off with B directly, he uses the Fire Release: Phoenix Sage Flower Nail Crimson, but is blocked by B. As he fends off several attacks from B, he then retreats atop of Nagato's summon and activates both of his Mangekyō Sharingan and wonders what will happen as he does. Much to Naruto's shock, the same crow Itachi placed inside Naruto before his Sage training comes out of his mouth.

As the crow comes out and lands on Naruto, Itachi and the crow lock eyes. Itachi then uses Amaterasu to seemingly attack Naruto, however his true aim was Nagato's dog summon. As Nagato asks what Itachi did with the crow, Itachi turns to him saying that his plan worked and attacks Nagato with Amaterasu. He then explains to Naruto that he had implanted the Mangekyō Sharingan that he received from Shisui into the crow that he had placed into Naruto and using Shisui's unique ability, was able to override the control Kabuto had over him with the genjutsu. He then explains that he had rigged it to react to his Mangekyō Sharingan embedding the message to "protect Konoha" foreseeing that Sasuke might transplant his eyes to gain the Eternal Mangekyō Sharingan and escape blindness and if he had attacked Konoha in any way the crow would come out and cast the genjutsu on him. As B asks him why he didn't do that from the beginning with Sasuke, Itachi tells him that he couldn't as without augmentations, Shisui's Mangekyō would take another decade to regenerate and in any case there were other things he wanted to do for Sasuke with his death. After being told by Naruto to leave the rest to him, he expressed his gratefulness that Sasuke had a friend like him before being assaulted by a large scale Shinra Tensei by Nagato who had removed the flames from his body and was being fully controlled by Kabuto.

As both Naruto whose soul was being removed by Nagato and B who had tried to free Naruto but was caught by Nagato are in danger of dying, Itachi summons his Susanoo and attacks Nagato, freeing both men. Itachi was able to lay the counterattack after blinding both the King of Hell as well as the chameleon summon who had shared vision with Nagato. As Nagato moves on the offensive again, using the Chibaku Tensei to trap them, after careful analysis Itachi concludes that attacking the sphere at the centre of the technique would effectively dispel it. As such with Itachi's Yasaka Magatama, B's Tailed Beast Ball and Naruto's Wind Release: Rasenshuriken, they effectively dispel the technique. As the smoke clears, Nagato finds himself impaled by Itachi's Sword of Totsuka and free from Kabuto's control, saying the sword would seal him and if he had any last words, he should impart them now.

After Nagato is sealed away, Itachi tells Naruto and Killer B that he'll deal with the Summoning: Impure World Resurrection because he already has a plan. When Naruto tells him that he'll stop the war on his own, Itachi tells him that, despite the fact that he has undoubtedly become stronger, he is forgetting all the people who acknowledged him and made him strong and that he shouldn't shoulder everything alone. Itachi goes on and tells Naruto that his father became Hokage because of Kushina and his friends and, if Naruto has the same dream, he should not forget his friends. He then stated that people who shouldered things alone, became egotistical and would eventually become just like Madara. Itachi then destroys his crow with Amaterasu, claiming it's useless against Sasuke and that Naruto, having inherited Shisui's feelings, can stop Sasuke without the eye. When Naruto tells Itachi to go see Sasuke he refuses, realising that he tried to do everything on his own and failed in the past, so he should leave his brother to his friends. Before leaving, Itachi asks B to look after Naruto and heads out to the battlefield.

Legacy
After the fight Madara collected Sasuke, tended to his wounds, and tried to befriend him when he awoke. When he removed his mask while doing the latter, Sasuke reflexively used Amaterasu on him. After quelling the flames, Madara explained that the Amaterasu had been sealed in Sasuke by Itachi, intended to protect him from Madara and whatever he might say. Sasuke was perplexed, so Madara went onto detail the history of the Uchiha clan, and the truth behind Itachi's life. Towards the end of his story, he explained that Itachi had been dying of disease, but had kept himself going with medicine so that he could die by Sasuke's hands, stating that if Itachi had battled with all his strength they wouldn't be having that conversation. He also stated that Itachi had pushed Sasuke to his limits during their battle to draw out Orochimaru, so that he could remove the latter's influence from his beloved little brother.

Sasuke was unwilling to believe the story. Madara persisted, saying that Itachi had entrusted the Uchiha name to Sasuke, hoping he would rebuild the clan on a new foundation of honour and nobility. For the sake of Konoha, and for Sasuke, he had been willing to die as a traitor and criminal. He had traded honor for disgrace and Sasuke's love for his hatred, and even then he had died smiling. Finally accepting the truth, Sasuke was crushed to find that the brother he had hated had actually been looking out for him all along. Upon realising the truth, he awakened his Mangekyō Sharingan and resolved to take vengeance against Konoha for the massacre of his clan and the fate they placed on his brother, regardless of Itachi's attachment to the village. He also agreed to start working with Madara and, as a result, is classified as an international criminal, something Itachi had tried to prevent by sacrificing everything he had, but even that had not been enough to deter Sasuke.

Danzō confirms that Madara's allegations that Itachi massacred the Uchiha for the coup are indeed true during his fight with Sasuke. Danzō states that Sasuke's actions destroy the importance of Itachi's legacy of a man who loved his village and was willing to sacrifice much for it.

Sasuke initially refused to transplant Itachi's eyes into his own sockets, due to the two of them having completely different visions of the future. However, after his reckless overuse of his own Mangekyō Sharingan from battling Killer B, A, Danzō Shimura and Team 7, Sasuke's eyesight had greatly deteriorated. As such, he decided to abandon his refusal, and take Itachi's eyes to use them to destroy Naruto at full power. The transplant was then commenced by Madara, and Sasuke stated that he felt Itachi's power flowing through him.

After being resurrected by Kabuto and freeing himself from the control of the technique, Itachi helped both Naruto and Killer B defeat and seal away Nagato. After that, Itachi claimed to have a plan to stop the Summoning: Impure World Resurrection, becoming an ally of the Allied Shinobi Forces.

Quotes

 * (To Sasuke)
 * (To Sasuke) "Being skilled isn't all that's it's made out to be. When you're strong, you become arrogant and withdrawn. Even if what you sought after was your dream."
 * (To Sasuke) "You and I are flesh and blood. I'm always going to be there for you, even if it's only as an obstacle for you to overcome. Even if you do hate me. That's what big brothers are for."
 * (To Sasuke as an infant) "Don't cry, Sasuke. Your big brother is here to protect you, no matter what happens."
 * (To Nekomata) "Growth occurs when one goes beyond one's limits. Realising that is also part of training."
 * (To the Uchiha clansmen) "I've had enough, there's no hope left for this pathetic clan."
 * "The people of this clan are all the same. You focus on the trivial, and lose sight of what's most important. Change is impossible, in this fog of ignorance. How can we evolve when regulation is all we know?"
 * "You hold onto the organisation and your clan name. These things limit us and limit our capacities… These things deserve to be shunned. It is foolish to fear what we've yet to see and know!"
 * (To Sasuke) "Foolish little brother, if you wish to kill me, hate me, detest me. And yet survive in an unsightly way. Run, run and cling to life, and when you have the same eyes as mine, come to me."
 * (To Kisame) "Those who turn their hands against their comrades are sure to die a terrible death."
 * (To Kisame, after he related the story of the sharks) "We are humans, not fish. We don't know what kind of people we truly are until the moment before our deaths. As death comes to embrace you, you will realise what you are. That's what death is, don't you think?"
 * (To Naruto) "You're still acting like a child. You're living in a fantasy world. You need to come to terms with the fact that you, as a ninja, will be forced to make impossible decisions like this."
 * (To Sasuke) "People live their lives bound by what they accept as correct and true. That's how they define "reality". But what does it mean to be "correct" or "true"? Merely vague concepts… their "reality" may all be a mirage. Can we consider them to simply be living in their own world, shaped by their beliefs?"
 * (Last words to Sasuke)
 * (About Shisui's teachings to him) "Self-sacrifice… A nameless shinobi who protects peace within its shadow… That is a true shinobi."
 * (To Naruto) "Your dream was your father's dream, wasn't it? Remember this well then. The village did not acknowledge him because he became Hokage. He became the Hokage because the village acknowledged him."
