Appearance

• ANBU attire: Wears Konoha ANBU clothing and carries a mask at his waist during the massacre 2 63.
• Uchiha clothing: Later wears high-collared Uchiha clan attire while serving Konoha’s remnants 167.
• Hair: Described as having short hair during his defeat in the Valley of Sanction 72.
• Original Mangekyō: His Amaterasu–Tsukuyomi eyes have triangular-shuriken patterns 75.
• Injuries and blindness: Returns to Konoha heavily bandaged, particularly around his eyes. By his final encounter with Sasuke, he is blind and without Sharingan 101 490.

Personality

Itachi initially treats loyalty to Konoha and the prevention of war as reasons to sacrifice his clan. He begins the massacre knowing that it means condemning himself morally, yet proceeds against civilians who welcome him into their homes. His tears and hesitation when confronting his parents show that his resolve does not eliminate the emotional cost 2 4.

His affection for Sasuke is entangled with manipulation. He feels guilty about his brother’s suffering but also welcomes Sasuke’s hatred as a means of strengthening the Sharingan. Even after the reanimated Uchiha confront him, he insists that he did nothing wrong and blames the clan and the world instead 33 148.

Repeated defeat and rejection eventually undermine that certainty. He questions whether Konoha’s surviving faction still deserves the name, while his fear of Ingetsu becomes difficult to conceal. After leaving Obito, he develops profound remorse and considers himself unworthy of marriage, family, or an ordinary life. Nevertheless, he protects Atai and agrees to an exploitative bargain to save the boy’s mother 166 189 490.

Abilities & Skills

Mangekyō Sharingan: Tsukuyomi and Amaterasu

• Tsukuyomi: Associated with his original left Mangekyō; Ingetsu later absorbs its ability 72 75.
• Amaterasu: Associated with his original right Mangekyō. He directs its black flames against Ingetsu’s Perfect Susanoo 71 72.
• Limit: Ingetsu evades the attack from the air and scatters the flames with Susanoo’s wings, endangering nearby shinobi rather than stopping him 71.

Susanoo

• Orange-red form: Uses third-stage Tengu Armor equipped with the Totsuka Blade and Yata Mirror 71 147.
• Totsuka Blade: Seals Orochimaru and the Eight-Branched Serpent, leaving Orochimaru no time to execute an escape plan 71.
• Yata Mirror: Serves as a defensive spirit weapon, but is destroyed alongside the Totsuka Blade by Ingetsu’s overwhelming strike 71.
• Yasakani no Magatama: His final resort against Sasuke manifests three rapidly rotating orange-red energy orbs 492.
• Use without eyes: Losing the Mangekyō does not necessarily remove Susanoo permanently; sufficient pupil power and chakra can preserve access. The blind Itachi later manifests it against Sasuke 76 490 491.
• Shared sealing world: Itachi’s Totsuka Blade and Ingetsu’s appropriated version connect to the same genjutsu sealing world. This connection unexpectedly releases Ingetsu’s sealed, reanimated Uchiha into Itachi’s camp 76 147.
• Limit: Severe injuries and depleted chakra weaken his defenses. Both Ingetsu’s Perfect Susanoo and Sasuke’s Kirin overwhelm his orange-red form 71 492.

Fugaku’s Amplification Techniques

• Left eye: Amplifies ordinary ninjutsu; Itachi uses it to enlarge and strengthen Water Release against Hikari 168 169.
• Right eye: Amplifies Susanoo, greatly increasing its size and power 169.
• Limit: Amplification does not grant flight. His enlarged fourth-stage black Susanoo remains vulnerable to Hikari’s Amaterasu tornado and complete Susanoo 169.

Genjutsu and Yin Release

• Uses Yin Release to create genjutsu and interfere with other people’s minds 71.
• Proposes placing a mental-control layer over Obito’s mind so that their combined Yin Release can resist Yachihoko’s influence 71.
• Identifies comparably strong Mangekyō mental power as a means of resisting Ingetsu’s mental erosion 95.
• Breaks free of Sasuke’s genjutsu during their final confrontation, although he later acknowledges that Sasuke’s genjutsu has surpassed his own 491 492.

Weapons, Movement, and Crows

• Swordsmanship: Carries out the massacre with a ninja blade and counters Kimimaro’s bone spear with a two-handed katana strike 2 65.
• Body Flicker: His distinctive footwork allows Izumi to recognize him from a distance during the massacre 2.
• Shuriken skills: Orochimaru previously witnessed him perform seemingly impossible shuriken training using the Sharingan 54.
• Crows: Uses a surveillance raven to watch Sasuke, a flock of crows to conceal Shisui’s eye, and a crow transformation to escape Konan’s paper attack 33 72 189.
• Blind combat: Deflects an ambush with gravel and kills two concealed attackers with returned kunai despite having no eyesight or Sharingan 490.

Equipment / Weapons / Items

• Ninja sword / katana — Used during the clan massacre and against Kimimaro 2 65.
• ANBU mask — Puts it on before killing a welcoming Uchiha family 2.
• Shisui’s left Mangekyō — Carries the Kotoamatsukami eye through a crow. Ingetsu identifies and retrieves it before Itachi can use an eye swap 72.
• Inabi’s three-tomoe Sharingan — Taken after killing Inabi; later stolen by Obito as Itachi’s last remaining Sharingan 9 89.
• Fugaku’s eyes — Preserved as a hidden fallback and transplanted after losing his original Mangekyō. He burns Fugaku’s body to conceal their removal 147.

Relationships

• Sasuke Uchiha — Younger brother. Itachi seeks to protect him while deliberately encouraging hatred as a source of strength. Sasuke rejects his justification for the massacre and ultimately kills him 4 33 493.
• Fugaku Uchiha — Father and clan head. Accepts Itachi’s decision, expresses pride in him, and entrusts Sasuke to him before being killed. Itachi later uses his eyes 4 147.
• Mikoto Uchiha — Mother. Itachi attempts to kill her during the massacre and later disregards her plea to spare the surviving Uchiha. Ingetsu prevents her death 4 33 64.
• Uchiha Ingetsu — Principal enemy. Defeats and tortures Itachi, repeatedly takes his eyes, and exposes his role in the massacre. Itachi secretly restores his power to seek revenge 72 147 171 189.
• Obito / the Masked Man — Massacre accomplice and tactical partner. Rescues Itachi with Kamui but also steals his remaining Sharingan and exploits his hatred. Their relationship eventually ends completely 2 71 89 490.
• Sarutobi Hiruzen — Hokage whom Itachi serves. Supports his appointment as Root leader, then dismisses him after his defeat and authorizes redistribution of Uchiha assets 94 95.
• Koharu and Homura — Konoha advisors who help construct his heroic public image and later use his restored strength to support Konoha’s remnants. They repeatedly prioritize their own survival over his 12 147 148 167.
• Izumi Uchiha — Clanswoman devastated by discovering his involvement in the massacre. His refusal to honor Mikoto’s appeal further destroys her faith in him 2 64.
• Shisui Uchiha — Close associate linked to his alignment with Konoha. In a parallel-world encounter, Shisui risks his life to protect Itachi from the older Sasuke 148 405 497 498.
• Orochimaru — Covets Itachi’s body and Sharingan; Itachi seals him with the Totsuka Blade 66 71.
• Atai and his mother — Offer him companionship and ordinary kindness in the Land of Demons. He protects them despite believing himself undeserving of their affection 490.

Story Role / Major Arcs

Uchiha Massacre and Official Cover-Up

Itachi joins the Masked Man in exterminating the Uchiha under Konoha’s direction. Their tasks are divided: the Masked Man targets the Police Headquarters and its Sharingan, while Itachi kills civilians throughout the compound 2 3.

At the clan head’s residence, he kills Fugaku and attempts to kill Mikoto, who escapes after an unexpected Mangekyō awakening. Sasuke later learns that Ingetsu’s shadow clone controlled Mikoto’s body to save her and showed him the truth of Itachi’s actions 4 33.

Konoha’s advisors blame Ingetsu’s rogue squad and portray Itachi as a hero who unsuccessfully opposed the slaughter. Itachi becomes Root’s leader, while Sasuke remains beside him only until Ingetsu can return 12 33 94.

Valley of Sanction Defeat

Itachi pursues the surviving Uchiha and continues advancing despite Mikoto’s appeal and apparent suicide attempt. Kimimaro and Orochimaru intervene; Itachi eventually seals Orochimaru but cannot withstand Ingetsu’s Perfect Susanoo 64 65 66 71.

After destroying his defenses, Ingetsu takes Shisui’s eye and Itachi’s original Mangekyō, then repeatedly stabs and interrogates him. Obito later abandons him near Konoha’s forces after taking Inabi’s eye 72 89 94.

Itachi returns with intelligence about Ingetsu’s mind control and chakra absorption. Hiruzen responds by dismissing him, and the village withdraws its medical team after bringing him home 95 101.

Hidden Recovery and Konoha’s Remnants

Itachi secretly transplants Fugaku’s eyes and pretends to remain helpless while awaiting revenge. After Konoha falls, its surviving forces take him away. His restored Susanoo briefly becomes a source of hope for Homura, until the shared Totsuka sealing world releases furious reanimated Uchiha into their camp 147 148.

Obito offers to make him Hokage of the remnants under Akatsuki’s influence. Itachi remains uncertain, questioning the faction’s identity and resenting his treatment as an expendable operative 166 167.

A mission brings him into conflict with Hikari. He unlocks Fugaku’s fourth-stage black Susanoo but is defeated; Ingetsu intercepts him afterward and absorbs Fugaku’s eyes 168 169 170 171.

Akatsuki and Exile

Obito introduces Itachi to Konan as a new Akatsuki member and provides replacement two-tomoe Sharingan. Ingetsu’s arrival triggers another defeat: the controlled Konan wounds Itachi, and Ingetsu removes his replacement eyes before forcing him into Kamui 189.

By the time Sasuke finds him years later, Itachi has severed ties with Obito and lives quietly in the Land of Demons. A masked group attempts to exploit his Uchiha bloodline by forcing him to father children, using Atai’s mother as a hostage 482 490.

Final Confrontation with Sasuke

Sasuke interrupts the coercion and attacks Itachi. Their battle exposes how far Sasuke has surpassed him: Kirin destroys the Yata Mirror and much of Susanoo, while Itachi’s final Yasakani no Magatama fails to secure the mutual death he seeks 490 491 492.

Sasuke kills him and burns his remains to prevent a contingency plan. Itachi’s death fulfills his wish to die at his brother’s hands and triggers Sasuke’s Mangekyō awakening 493.

Parallel-World Counterpart and Training Clone

An earlier Itachi is depicted as a double agent torn between the Hokage’s ANBU and his clan. He fears that a Uchiha attempt to seize power will destroy Konoha, while Shisui shares his uncertainty about trusting the village’s leadership 405.

After the main Itachi’s death, Sasuke encounters a younger counterpart in a parallel world and severely beats him. Shisui intervenes but is also overwhelmed; neither initially understands who their attacker is 496 497 498.

Ingetsu later gives Sasuke Itachi’s Mangekyō power to complete his Eternal Mangekyō and creates a training realm whose first opponent is an Itachi clone 503.
