Itachi holding his infant brother, moments before the Nine-Tails' attack on Konoha.
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.
In the anime it was shown that during their childhood, Itachi
made a game of collecting paw prints of cats from a domestic ones to
lions with his brother. The last paw print to be collected was Nekomata's who Itachi had defeated and requested him to fight Sasuke with all his might when he got older.
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.
A young Itachi with his family.
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.
Itachi massacres the entire Uchiha clan.
Before the fateful night arrived, Itachi discovered the existence of Tobi,
who was attempting to rekindle the flames of war in Konoha. In return
for not attacking Konoha, Itachi offered to help Tobi claim vengeance
against the Uchiha for turning their backs on him decades earlier; Tobi
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 in order to awaken the Mangekyō
Sharingan, he had to kill the person he was closest to, and that when
they met again, they should have the same eyes.
Itachi pleads with the Third to protect Sasuke.
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 Tobi, Itachi also had a lover, whom he killed during the Uchiha clan massacre.[4] 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 joins Akatsuki.
Itachi joined Akatsuki
in order to keep an eye on the organisation, along with Tobi, 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.
Itachi crying after murdering his entire clan.
Ever since his first appearance, Itachi had always been mysterious
and acted as though he was 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 his beloved brother, Sasuke. Even at a young age, Itachi vowed
he would protect Sasuke, while he was only an infant, at all costs just
prior to the Nine-Tails' Attack on Konoha.
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 didn't
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 Tobi 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,[5]
although this was all an act, as his true intentions for joining the
organisation was to spy on it from within. Despite this, 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.
Itachi poking Sasuke - something he did regularly.
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.[6]
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.[7]
Itachi's appearance after joining Akatsuki.
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 Vermilion (朱, shu). 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 appear to have black sclera like the other shinobi that Kabuto Yakushiresurrected, except for his activated Sharingan. He is also clad in a dark-red cloak.
Itachi's usage of crows in genjutsu.
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. Tobi said that Itachi
never ceased to amaze him. However, despite his impressive abilities, he
never underestimates his opponents, 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 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.
Itachi possessed very high-level taijutsu skills despite not
specialising in it. This was demonstrated when he easily dispatched threefellowUchiha, 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. His skill in taijtusu was great enough to keep up with Naruto Uzumaki in his Nine-Tailed Chakra Mode and Killer B, even though he had to retreat when facing both together.[8]
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.
Itachi using Fire Release: Great Fireball Technique.
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.[9] 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;[10]
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.[11] He was also very skilled with shuriken, Sasuke stated that he was best with shuriken, even more skilled than their father.[12] During their fight at the Uchiha Hideout, Itachi was able to counter every one of Sasuke's shuriken with his own.[13]
Itachi's Sharingan.
Being of the Uchiha clan, and as noted by Kakashi, Itachi was a true successor of the Sharingan,[14]
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.[15] According to Ao, he could also use his genjutsu to take control of other individuals from a long distance.[16]
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.
Itachi's 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.[17] With his right eye he could use Amaterasu, a ninjutsu
which allowed him to create black flames, that he could direct by
moving his eye, to burn through anything in its path, including fire
itself. His final technique was Susanoo, the "Tempestuous God of Valour" (勇武の荒神, Yūbu no Aragami),[18] 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.
Itachi's Susanoo, complete with the Yata Mirror.
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.[19]
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.[20]
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.[21]
Itachi has been shown to possess an extremely high intellect, being
able to deduce the inner workings and weaknesses of incredibly powerful
techniques, even while under pressure.[22] Itachi appears to have deduced a method of defeating the Summoning: Impure World Resurrection technique altogether.[23]
His intellect was such that he was able to not only orchestrate the
entirety of his battle against Sasuke years in excess of its actual
occurrence, but restrain himself throughout the battle in order to bring
about his intended outcome.[24] He was even able to account for the possibility that his plan wouldn't go as intended by sealing his power into Sasuke and placing a special crow inside of Naruto Uzumaki in the eventuality that Sasuke turned against the village.[25] Even Tobi himself admitted that if he hadn't kept a few secrets from Itachi he'd be dead.[26]
Itachi and Kisame's début.
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 meets his little brother once more.
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.
Itachi and Kakashi clash.
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.
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.
Itachi's talk with Naruto.
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.
Itachi and Sasuke battle.
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 Uchiha, 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.[27]
Itachi faces Orochimaru's Eight Branches Technique.
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.
Itachi's last smile to his brother.
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.
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 Nekomata 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.
Itachi and Nagato en route.
As the Fourth Shinobi World War against the Allied Shinobi Forces commences, Itachi is mobilised alongside Kakuzu, who carries an immobile Nagato on his back. Later supporting the latter as they walk, the now isolated pair continue throughout the night, conversing about Akatsuki. Itachi then remarks that their two dōjutsu together could achieve anything, which is likely why their summoner would wait for the opportune moment to use his abilities. After pausing at a shrine and discussing Kabuto's influence on Tobi's plan, they march onwards till dawn, when they encounter Naruto and Killer B.
Itachi clashes with Killer B.
Surprised by Naruto's growth and subjugation of the Nine-Tails, Itachi attempts to ask him something, but he instead attacks the pair involuntarily with his Fire Release: Great Fireball Technique. Discerning Kisame's death, from B's possession of Samehada, he engages Naruto directly. Exchanging both dialogue and blows, Itachi is shocked and disappointed by his brother's decision to destroy Konoha, while learning Tobi was aware of the truth behind the Uchiha clan massacre.
Imploring Naruto to keep the details secret, to maintain his clan's
honour, he then entrusts dealing with Sasuke to him. As Itachi confronts
B, he catches him in a genjutsu, after using his Fire Release: Phoenix Sage Flower Nail Crimson technique. However, fending off several attacks, he retreats atop Nagato's summon and activates his Mangekyō Sharingan, wondering what would happen as he does. Much to Naruto's shock, the crow Itachi had placed inside him emerges.
Itachi attacks Nagato's summon with Amaterasu.
As Itachi and the crow's eyes meet, he seemingly prepares to attack Naruto with Amaterasu, however, it instead hits Nagato's other
summon. Realising his plan had succeeded, Itachi turns on Nagato and
engulfs him in black flames, before leaping towards Naruto. He then
explains how he had implanted the eye that he received from Shisui into the crow to use Kotoamatsukami with the embedded command "protect Konoha",
which is why he was able to override Kabuto's control. Informing them
that the crow had been rigged to react to his Mangekyō Sharingan and was
originally intended for Sasuke, in the possibility that he attacked
Konoha after transplanting eyes to gain the Eternal Mangekyō Sharingan,
Itachi expresses his belief that only Naruto could stop his brother.
Asked by B why he didn't just use it on Sasuke from the beginning, he
reveals that he was unable to because excluding augmentations, such as Hashirama Senju's chakra, Shisui's Mangekyō would take a decade to regenerate.[29]
He also told them that he had other intentions behind his death.
Grateful that Sasuke had a friend like Naruto, the three are then
assaulted by Nagato's large scale Shinra Tensei, who was now under Kabuto's full control.
Itachi saves Naruto and B from Nagato.
With both of the jinchūriki in grave danger at Nagato's hands, Itachi intervenes and frees the two using his incomplete Susanoo. It is later revealed that he had previously blinded both the King of Hell and the chameleon summon with a barrage of kunai, to approach undetected despite the Rinnegan's shared vision. Releasing them from his Susanoo's grasp, the three begin to be drawn upwards by Nagato's Chibaku Tensei.
After careful analysis, Itachi surmises that attacking the sphere at
the centre of the technique would effectively dispel it, so he proposes
that they use the attractive force to direct their strongest long-range
techniques at it. Using Yasaka Magatama in combination with the others'attacks, they confirm his conclusion and before the dust settles, Nagato finds himself impaled by Itachi's Sword of Totsuka. Disclosing that the sword would seal him, he states that if Nagato had any last words, he should impart them now.
Itachi incinerates the crow.
After Nagato is sealed, Itachi states that he would deal with the Summoning: Impure World Resurrection
technique as he had already formulated a plan, allaying Killer B's
concerns by reiterating that every technique had a weakness. However,
when Naruto decides to stop the war on his own, Itachi tells him that
despite becoming stronger, he is forgetting all those who he wanted
acknowledgment from and that with those egotistical thoughts, he would
eventually become like Tobi. Reminding him that his father became Hokage because of Kushina and those around him, he states that if Naruto has the same dream, he should not forget his friends. Itachi then incinerates
his crow, stating that the eye was useless as it could not be
reactivated for another decade and that Naruto, having inherited
Shisui's feelings, could stop Sasuke without it. Refusing to see his
brother, after realising that he tried to do everything on his own and
still failed, he resolves to leave Sasuke to his friends instead. Asking
B to look after Naruto, Itachi departs.
While on his way to stop the Impure World Resurrection, Itachi runs across Sasuke, much to the latter's shock.
After the fight Tobi 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, Tobi explained that the Amaterasu had been sealed
in Sasuke by Itachi, intended to protect him from Tobi and whatever he
might say. Sasuke was perplexed, so Tobi 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. Tobi 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 Tobi
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 Tobi'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 Tobi, 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.
