Background / History

Clan Leadership and First Contact with Kei

Fugaku returns from the Iwa front and summons Kei after hearing about his battlefield achievements. He questions the claim that Kei awakened directly to a Three-Tomoe Sharingan, noting that the clan’s records contain no such precedent and that Kei’s immediate proficiency suggests earlier experience 54.

Their first discussions test Kei’s loyalty to both the clan and the village, particularly through questions about Kakashi possessing Obito’s Sharingan. Fugaku acknowledges that Kei’s resentment is understandable because the clan had provided him little support. He offers resources and training in exchange for participation in clan affairs, then authorizes Kei’s access to the clan library 55 56.

Fugaku presides over a clan divided between hardliners and moderates. Both factions pressure him to seek the Hokage position, while hardliners attempt to turn Kakashi’s Sharingan into a political confrontation with Konoha’s leadership 67 68 69.

From Suspicion to Partnership

After Kei helps save Itachi from falling off a cliff, Fugaku invites him home and asks for his assessment of the clan’s problems. Kei’s arguments about the Police Force’s role in isolating the Uchiha persuade Fugaku, though he warns against voicing those accusations publicly. He also raises the possibility of Kei mentoring Itachi 74 75 76.

Fugaku subsequently proposes changing the Guard Division. However, Uchiha Yuu’s disappearance leads him to investigate battle traces and temporarily restrict clan members’ movements. His investigation culminates in a masked genjutsu confrontation with Kei, whose revelation of the Mangekyo Sharingan overturns Fugaku’s expectations 87 94 96 99.

Recognizing that he cannot control Kei, Fugaku chooses cooperation. Together, they plan to support Namikaze Minato and build alliances with smaller clans and commoner ninja rather than rely solely on negotiations with the existing village leadership 100 102.

Guard Division Reform and Minato’s Government

Fugaku becomes involved in Kei’s secret experiments, maintaining the captive Yuu during Kei’s absence and providing resources for research into Mangekyo awakening. Their cooperation has limits: he refuses Kei’s proposal to use Yuu’s family and girlfriend as experimental props, instead offering an emotion-enhancing drug and access to death-row inmates 105 155 156.

He agrees to transfer the Guard Division to Kei after Minato’s inauguration. Following the appointment, he advises Kei on squad leadership and supports the deployment of Uchiha elites into Minato’s Anbu 194 206 224 235.

Their eventual division of responsibility places Fugaku in charge of internal clan affairs and Kei in charge of external matters. This arrangement improves the clan’s position while leaving Fugaku more time for his family 348 376.

Nine-Tails Incident

During the Nine-Tails crisis, Fugaku agrees to expose his Mangekyo to Minato despite concerns about secrecy and ocular consumption. Protected by Kei’s Shadow Clone and its Susanoo, he overpowers the beast’s consciousness through genjutsu. Kushina then reinforces the restraint with her sealing chains, allowing Minato to proceed with his sealing plan 275 276.

His contribution strengthens the Uchiha’s prestige and supports Minato’s policy of integrating the clan into Konoha. Fugaku represents the clan in reconstruction discussions, although he remains concerned that rapid expansion of their influence could damage their relationship with the Fourth Hokage 283 284.

Eternal Eyes and the Kumogakure War

After receiving and adapting to the Eternal Mangekyo, Fugaku challenges Kei to a sparring match. His ninjutsu initially outclasses Kei’s, but the contest escalates into a destructive Susanoo battle that ends with Fugaku’s defeat and a reprimand from Minato 295 348 372 373 374.

On the Kumogakure front, Fugaku withstands the Fourth Raikage’s attacks with Susanoo and burns his arm with Amaterasu. In a later confrontation, he counters the Raikage’s decision to target ordinary Konoha ninja by threatening Kumogakure’s forces in return 401 408 411.

Fugaku leads Konoha ninja toward the Kumogakure camp after the destructive clash involving Kei and the Eight-Tails. He returns to Konoha amid celebrations, gaining substantial political capital and the allegiance of the Second Division. Despite that success, he seeks Kei’s guidance because he has not mastered the fourth stage of Susanoo 431 434 441 442.

He later leads Konoha’s military-aid force toward Kumogakure, accompanied by Hyuga Hiashi 472.

Potential Plan and Later Responsibilities

Fugaku participates in the Potential Plan involving Shisui, Itachi, and Sasuke, but repeatedly worries about the psychological damage required to awaken their Mangekyo. He observes the boys’ growing bond and fears that exploiting it could destabilize his sons 443 587.

He manages clan opinion surrounding Shisui while coordinating with Kei. Later, he openly confronts Hiruzen and his allies at a jonin meeting over abuses of authority, with Kei supporting his accusations 637 651 652.

When Kei leaves for Kumogakure, Fugaku agrees to oversee the Military Police Force and discusses his sons’ condition with him. He also accompanies Minato on a diplomatic journey, bringing Itachi to develop his experience. In the latest documented events, Fugaku uses Izanagi to revive Shisui, who returns to Akatsuki 669 697 761.

Appearance

• General appearance: Described as a middle-aged man 186.
• Mangekyo pattern: Resembles a smaller version of Itachi’s Mangekyo design, with three additional dots 99.
• Combat manifestation: His Susanoo is golden and develops a massive four-armed form 373 401.

Personality

Fugaku is restrained, cautious, and accustomed to compromise. He mediates factional arguments rather than allowing them to become open conflict, and his initial strategy is to negotiate peacefully with Konoha while suppressing unrest within the clan. Kei regards this patience as both a strength and a source of indecision 54 67 100.

His central ambition is the Uchiha Clan’s secure place within Konoha, not the Hokage title itself. Once that goal is achieved, he expresses no jealousy toward Minato and values the freedom to accompany his wife and children. He also intends to avoid becoming an elder who obstructs the next generation by refusing to relinquish power 348 376 587.

His pragmatism can be ruthless: he becomes Kei’s accomplice in captivity and forced-awakening experiments. Nevertheless, he rejects using Yuu’s innocent relatives as pawns and is deeply troubled by plans that could traumatize his own sons 105 155 156 232 443 587.

Beneath his formal composure, Fugaku enjoys battle. His sparring match with Kei gives him a rare opportunity to express excitement normally suppressed by his responsibilities as Clan Head 373.
