Background / History

Fugaku is the legitimate son of an Uchiha elder and receives the clan’s best ninja education from childhood. His Sharingan initially awakens after he witnesses clansmen die, and he continues training seriously afterward 22 111.

Before Hanma becomes clan head, Fugaku frequently seeks his advice on taijutsu. Their early relationship is informal and friendly: Hanma flicks his forehead and mocks his slow Sharingan development, while Fugaku calls Hanma a freak for becoming powerful without awakening his eyes 1.

Hanma’s eventual leadership changes Fugaku’s development, family life, and political outlook. Rather than becoming the resigned clan head described by alternate Sasuke, he becomes Hanma’s outspoken supporter, the Uchiha’s ruthless enforcer, and a father who initially favors a relaxed upbringing for his children 123 130 277 322.

Appearance

Fugaku develops a muscular physique that sharply distinguishes him from his less physically trained alternate-world counterpart 328.

• Hair: Tousled bangs during his youth, shown plastered to his forehead after exhausting training 23.
• Eyes: Sharingan that progresses from two tomoe to three tomoe and Mangekyō patterns 1 82 222.
• Build: Thick arms and a powerful body; alternate Sasuke’s sword leaves white marks on his fist without drawing blood 319 322.
• Demonic form: Black flames, azure lightning, horns, and a thorned tail. Fugaku describes this as an imperfect imitation of Hanma’s Heavenly Demon state 391.

Personality

Fugaku begins as a sociable, ambitious young Uchiha who admires Hanma and willingly challenges him despite their enormous difference in strength. His determination and comprehension impress Hanma during their early sparring sessions 1 22 23.

His devotion becomes theatrical after a wartime mistake nearly endangers Hanma. Overcome by shame, he reaches for a suicide blade; Hanma instead gives him a lifelong obligation to live, serve, and make amends. Fugaku embraces this purpose with almost worshipful enthusiasm 64.

He is affectionate toward family and friends but exceptionally brutal toward enemies. As the Uchiha’s “root,” he favors decisive raids against hostile schemers rather than discreet investigations or prolonged political maneuvering. His reputation becomes frightening enough that parents invoke his name to stop children from crying 130 277.

Fugaku’s pride remains sensitive to comparison. Minato’s achievements and Obito’s Kamui repeatedly make him feel inadequate, even after he acquires powerful ocular abilities of his own. In the alternate world, he enjoys receiving the admiration that his original family rarely gives him, since they live among even stronger fighters 225 319 333.

His later combat philosophy emphasizes conscious control rather than rage or instinct. Against Unohana and Zaraki, he argues that physical evolution and complete command of one’s strength matter more than techniques refined within an inferior power tier 391.

Abilities & Skills

Taijutsu and Physical Control

Fugaku trains under Hanma’s guidance and eventually claims to have inherited and imitated Hanma’s martial path more deeply than anyone else 1 391.

• Maintains an early-morning taijutsu routine after decades as a ninja 331.
• Catches and crushes alternate Minato’s Rasengan barehanded, blocks another without injury, and defeats him with a punch and elbow strike 334.
• Grabs both Kenpachis’ Zanpakutō, redirects Unohana through footwork, and destroys Zaraki’s internal organs with his hands 391.
• Rejects emotional stimulation as a substitute for deliberate control over the body’s full strength 391.

Sharingan and Genjutsu

Fugaku possesses unusually abundant ocular power, leading Hanma to identify his potential for a future Mangekyō awakening 111.

• Traps Nawaki in Sharingan genjutsu; Hanma dispels it with Predatory Blood Qi 22.
• Uses genjutsu for disguise and information gathering after entering another timeline 327.
• Places alternate Mikoto, Itachi, and Sasuke in pleasant dreams while confronting his counterpart 329.
• Subdues eight Tailed Beasts simultaneously with Mangekyō genjutsu 343.
• Erases alternate Konan’s memories of Yahiko and Nagato and makes her believe she is an amnesiac Uchiha 341.
• Does not regard genjutsu as his specialty despite these applications 334.

Amaterasu

Initially awakened in Fugaku’s left eye, Amaterasu produces black flames. Hanma advises him to exploit its immediacy and explosive force rather than treat it as a broad area attack 222 226.

• Burns Danzō’s arm during the confrontation with the Nine-Tails host 255.
• Destroys alternate Minato’s Flying Thunder God kunai, removing his prepared teleportation points 334.
• Produces a massive pillar of black fire that breaks his counterpart’s second-stage Susanoo without visible ocular strain 329.
• Proves comparatively inefficient against the enormous Three-Tails; experienced enemies can counter or escape its segmented attacks 225 227.

Takemikazuchi

Initially awakened in Fugaku’s right eye, Takemikazuchi releases violet-black or blue-violet lightning capable of injuring both body and soul 222 226 337.

• Damages more than half of the Third Mizukage’s soul; the spiritually connected Three-Tails shares the pain and becomes berserk 225.
• Can be conducted through a sword 320.
• Penetrates his alternate counterpart’s Tengu Susanoo with Takemikazuchi: Soul-Lashing Lightning 329.
• Chains through Root operatives, reducing their bodies and souls to dust 336.
• Supports lethal mutual-destruction tactics when combined with Izanagi 283 284.
• Must connect to be effective: Izuna evades it, Nagato absorbs it with the Rinnegan, and original-timeline Obito’s intangibility frustrates Fugaku 255 319.

Susanoo and Heavenly Demon Release

Fugaku develops Susanoo from manageable skeletal and half-bodied forms into a Tengu manifestation. His later Heavenly Demon Release combines a giant War God-like body with his signature flames and lightning 281 330 339.

• Uses Tengu Susanoo as a public display of military and political authority 330.
• Overpowers the Nine-Tails physically while Amaterasu and Takemikazuchi burn its body and soul 339.
• Reveals a later demonic form that withstands Unohana’s ultimate blood blade with only a white mark 391.
• His ordinary Mangekyō initially cannot safely sustain the Tengu stage; Setsuna warns of possible blindness 281.
• His later transformation remains an imitation of Hanma’s power, not its equal 391.

Hanma Flesh and Absorption

Hanma Flesh gives Fugaku access to a portion of Hanma’s extraordinary physical traits, including limited Space-Time Bedrock properties 337.

• Resists alternate Obito’s Kamui vortex rather than being dragged into its dimension 336 337.
• Absorbs stolen Mangekyō eyes and incorporates their ocular techniques 336 337.
• Directly absorbs the Nine-Tails’ chakra without first becoming its conventional jinchūriki 339.
• Processes the stolen Rinnegan for compatibility with alternate Mikoto and makes her kin 342 354.
• Cannot match Hanma’s vastly greater spatial anchoring power 337.

Kamui

Fugaku acquires dual Kamui by taking both eyes from alternate Obito during Nine-Tails Night 336 337.

• Manipulates space-time to pull Obito out of his phased state 337.
• Exiles an entire barrage of Nine-Tails Tailed Beast Bombs into another dimension 339.
• Gains the space-time ocular ability Hanma sought from his otherworld expedition 343.
• His original resistance to Kamui comes from Hanma Flesh, before he steals the technique 337.

Izanagi and Replaceable Sharingan

Fugaku researches a combat method that pairs his offensive Mangekyō with a replaceable Three-Tomoe Sharingan used for Izanagi 283.

• Carries spare eyes obtained from the clan storehouse 283.
• Replaces blinded eyes directly rather than implanting them in his arm or using a Transcription Seal 283.
• Survives a battlefield detonation while helping Kisame kill Hanzō 284.
• Requires sacrificing an eye; his willingness to treat stored Sharingan as expendable resources enables repeated high-risk tactics 283 284.

Ten-Tails Power and Otherworld Energy

After taking the Nine-Tails’ chakra, Fugaku uses the Heavenly Demon Seal to crush and absorb the other eight Tailed Beasts, effectively becoming a Ten-Tails Jinchūriki 343.

• Reaches the Six Paths level and returns with chakra valuable to Hanma’s spatial development 343.
• Suppresses resistance within the Ten-Tails’ chakra associated with Kaguya’s will and the distant moon 343.
• Cannot prevent the alternate world from rejecting and expelling him 343.
• Survives the return through Space-Time Turbulence, but arrives injured 343.

Equipment / Weapons / Items

• Chakra Metal blade — Used with Fire-natured chakra for Uchiha Style Kenjutsu: Mirror Flame Leap, producing a large flaming shockwave 23.
• Tachi — Used in sword combat and later coated with Takemikazuchi lightning 82 320.
• Spare Three-Tomoe Sharingan — Clan-storehouse eyes reserved for Izanagi and replaced after blindness 283 284.
• Sealing talisman — Unsealed during his battlefield eye-replacement procedure 283.

Relationships

• Hanma — Friend, taijutsu mentor, clan leader, and the central object of Fugaku’s loyalty. Fugaku defends his reforms and undertakes the otherworld resource mission for him 1 64 123 333 343.
• Mikoto — Wife and mother of his sons. In their original timeline, she is an independent businesswoman and welfare benefactor whose standing within the clan exceeds Fugaku’s 111 327.
• Alternate Mikoto — Becomes his partner after he kills and replaces her husband. She eventually recognizes his different identity, chooses him, and receives compatible Rinnegan and kin enhancement 329 341 342 354.
• Itachi — Elder son, raised with “happy education” following Hanma’s advice. Fugaku later worries about his lack of training motivation 319 322.
• Sasuke — Younger son. Fugaku worries that his carefree upbringing has limited his progress and asks Minato to arrange a spar with Naruto 319.
• Alternate Sasuke — Intruder whose Six-Tomoe Rinnegan excites Fugaku’s paternal pride. Their confrontation leads to revelations about the Uchiha massacre and his counterpart’s death 319 320 322.
• Minato — Friend and recurring rival whose superior abilities repeatedly frustrate Fugaku. Their original-timeline familiarity helps him counter and defeat the alternate Fourth Hokage 129 319 334.
• Nawaki — Close friend, sparring target, and battlefield protector. Their insults conceal genuine concern; Nawaki saves him from the berserk Three-Tails 22 225 227.
• Setsuna — Former clan head and senior authority. He disciplines Fugaku’s wartime mistake, protects him during the leadership exchange, and warns him about Mangekyō limitations 64 82 281.
• Uchiha Shin — Clan elder whose death and demand for vengeance shape Fugaku’s offensive Mangekyō abilities 183 222 225.
• Obito — Younger clan prodigy and teacher of Fugaku’s sons. Fugaku resents the advantage provided by his Kamui, then acquires that ability from Obito’s alternate counterpart 319 333 336 337.
• Kisame — Battlefield partner against Hanzō. Fugaku’s willingness to sacrifice himself earns Kisame’s respect 284.
• Orochimaru — Allied researcher and combatant who protects Fugaku from Izuna’s killing blow after regenerating from decapitation 255.
• Kaguya — Hanma’s close companion and Mikoto’s friend; she exposes Fugaku’s involvement with a second Mikoto and unsettles him despite his Six Paths strength 343.

Story Role / Major Arcs

Early Training and the Wartime Pledge

Fugaku participates in Hanma’s instruction alongside Nawaki, Minato, and Kushina. After catching Nawaki in genjutsu, he challenges Hanma with Sun Halo Dance and later Mirror Flame Leap. Hanma recognizes his talent but decisively defeats him 22 23.

As wartime deputy commander, Fugaku trusts Danzō’s orders and withdraws his troops, leaving Hanma potentially caught between two Tailed Beasts. Setsuna condemns the decision. Hanma refuses to punish him through death and instead makes continued service his means of atonement 64.

Hanma’s Succession and the Uchiha’s “Root”

Fugaku represents the clan’s radical faction and eagerly anticipates Hanma’s succession. He leads a coordinated assault during the public leadership exchange, only to be overwhelmed. Hanma subsequently praises him and the other young elites before the clan, turning their fear into renewed loyalty 80 82 84.

After witnessing Kumogakure manufacture a diplomatic crisis against the Hyūga, Fugaku decides that Hanma needs someone willing to perform the clan’s darker work. He adopts the role of the Uchiha’s hidden “root,” eventually becoming intelligence chief and Military Police head 130 280 327.

Mangekyō Awakening and the Fourth Shinobi World War

Shin’s death drives Fugaku’s Mangekyō toward pure offense. He severely injures the Third Mizukage with Takemikazuchi, but the resulting Three-Tails rampage nearly kills him. Nawaki rescues him, and Hanma cautions him against exhausting his eyes or allowing newfound strength to distort his judgment 222 225 226.

Fugaku later helps defeat Danzō and openly rejects Izuna’s attempt to claim authority over the modern Uchiha. During the wider war, he develops replaceable-eye Izanagi tactics and joins Kisame in killing Hanzō 255 283 284.

Alternate Sasuke’s Arrival

Fugaku and Minato confront Sasuke and Boruto after they arrive from another space-time. Fugaku tests Sasuke directly, displaying physical strength far beyond the father Sasuke remembers 319 320.

The visitors’ account of the Uchiha massacre enrages Fugaku, particularly the claim that his counterpart accepted death rather than resist. He initially rejects any resemblance, then acknowledges that Hanma’s absence could have left his own clan vulnerable to a similar decline 322 323.

Otherworld Conquest

Sent to gather resources for Hanma, Fugaku enters a timeline shortly before Nine-Tails Night. He kills its Fugaku, takes his eyes, burns the corpse, and assumes his position as clan head. He then destroys the Anbu who challenge him and defeats the Fourth Hokage in a public duel 327 329 330 334.

During the Nine-Tails attack, he mobilizes the Uchiha, sends them to rescue civilians, kills obstructing Root forces, and confronts alternate Obito. He steals both Kamui eyes and coerces Minato into eliminating Konoha’s senior leadership in exchange for saving Kushina and subduing the Nine-Tails 336 337 339.

Fugaku takes Nagato’s Rinnegan, kills Nagato and Yahiko, and alters Konan’s memories. He then defeats the opposing villages’ leadership and absorbs the remaining Tailed Beasts. The world forcibly expels him, leaving alternate Mikoto and Minato to manage the aftermath 341 343.

Soul Society Battle

Fugaku faces Unohana and Bankai-transformed Zaraki together. After dismantling their initial attacks, he reveals his demonic form, survives Unohana’s calculated finishing strike, and kills both Kenpachis. Their defeat demonstrates his principle that superior physical development can overwhelm technique and battle instinct 391.

Alternate Counterpart

The Fugaku encountered before Nine-Tails Night is a separate individual, not an earlier version of the Hanma-trained Fugaku 327 329.

Feature	Alternate-world counterpart
Position	Uchiha clan head with severely weakened authority after costly wartime losses 328
Mangekyō abilities	Left eye predicts the near future in small increments; right eye glimpses fragments of a distant future 328
Family relationship	Estranged from Itachi after taking him to war and imposing heavy expectations on him 328
Combat ability	Uses half-bodied and Tengu Susanoo, but cannot withstand the visiting Fugaku’s Amaterasu and soul-damaging lightning 329
Fate	Dies following physical defeat and deliberate psychological torment. The visiting Fugaku removes his eyes, destroys his body, and replaces him 329

His prophetic vision of a Six Paths-level Fugaku ruling the world depicts the visitor who replaces him, rather than his own eventual advancement 328 329.

Notable Quotes

“From now on, in my heart and in the hearts of the entire Uchiha Clan, there will only be one sun: Brother Hanma!!” 64

“Why would a family conversation need a confidential room? That would not be opening our hearts to one another—it would be holding a clan meeting.” 331

“A true martial artist can completely control their own power. They do not need such shallow methods to stimulate their mind and gain strength...” 391

Trivia

• His role as the Uchiha’s “root” does not make him a member of Danzō’s Root. It describes his commitment to undertaking dangerous and morally questionable work for Hanma and the clan 130.
• Despite later near-strainless Mangekyō use, his Eternal Mangekyō status is not conclusively established in the supplied account: his counterpart suspects it, while Konoha’s elders debate and dismiss that explanation 329 335.
• Konoha parents use the threat “Stop crying, or we’ll send you to Uchiha Fugaku!” to frighten children into silence 277.
• Even after reaching the Six Paths level, the prospect of explaining his relationship with alternate Mikoto to his original wife terrifies him—especially because she has Kaguya and Hanma’s support 343.
