Background / History

Becoming Haku’s Teacher

Orochimaru and his two companions brought Haku to Konoha six years before Haku began learning the Shadow Clone Jutsu. Impressed by the child’s observation and analysis of the village’s increasing mission burden, Orochimaru offered to supervise him if he applied for early graduation. Haku initially declined because he still needed basic ninjutsu and medical training 12.

Orochimaru subsequently led the team of Haku, Uchiha Yu, and Hyuga Riko. His entrance test involved ambushing the students, knocking them unconscious, and leaving them outside overnight. He criticized their poor vigilance and lack of teamwork, then announced that similar tests would recur. Their first assignment was presented as a B-rank mission, with Orochimaru initially saying he would not accompany them 14 15.

War with Kumogakure

After the team encountered Iwagakure ninja, Orochimaru reported his interrogation findings to Hiruzen Sarutobi. He warned that Ōnoki might exploit Konoha’s war with Kumogakure and accepted orders to stabilize the front. He also requested that his injured disciples be sent to him through a supply-transport assignment once they recovered 22.

Haku’s rapid recovery reminded Orochimaru of his former disciple Nawaki. He assigned Haku to patrol with Minato Namikaze, offered to obtain Tsunade’s advanced healing techniques, and warned that repeated injuries consumed the finite activity of human cells. During the decisive battle, he instructed Haku to remain nearby and led Ino-Shika-Cho against the Fourth Raikage and Killer B 30 32.

When Haku remained unconscious for three days after being struck by the Eight-Tails Jinchuriki and the Third Raikage, Orochimaru reprimanded the medical staff and personally checked on him when he awoke 34.

Human Experiments and Political Isolation

Orochimaru obtained the Creation Rebirth and Yin Seal scrolls from Tsunade for Haku. After the war, he became less publicly visible; Haku suspected that competing political interests were suppressing his reputation 36 38.

By Haku’s Sharingan transplant, Orochimaru had begun human experimentation. He agreed to the operation partly to collect firsthand data, drawing on earlier cases in which transplanted Sharingan caused emotional corruption or excessive chakra consumption. Haku cooperated with examinations afterward 40.

Orochimaru also intervened with the Uchiha clan to prevent trouble over Haku’s transplanted eye. He linked Haku’s participation in his experiments to protection for Haku’s friends, presenting their increasingly close association as a way to secure both of their positions 42.

Nawaki’s death through framing, along with Orochimaru’s own framing and lost chance to become Hokage, damaged his stability. Although he still loved Konoha, he considered destroying it if the village declined 44.

Sound Village and Defection

Haku established the Sound Village in the Land of Fields and informed Orochimaru of its Daimyo-backed funding, recruitment efforts, and shortage of ninjutsu. Orochimaru later helped finance its development alongside Uchiha Yu 44 96.

During his dealings with Root, Orochimaru killed a subordinate who questioned him and planned to leave a backdoor in an improved Tongue-Cutting-Root-Destruction Jutsu. Danzo subsequently supplied Ohmura as an experimental subject for work intended to eradicate Root members’ self-awareness 44.

Orochimaru continued commanding Konoha forces, later fighting Kumogakure alongside Uchiha Fugaku. He also passed Minato confirmed intelligence about plans to hide Kushina under Root’s guard, prompting Minato to return to Konoha 136 138.

After the war, Konoha officials confirmed that Orochimaru had used village ninja in live experiments. Before punishment could be decided—and after news of an ambush on the Third Hokage—Orochimaru defected and killed Danzo 150.

Redirected Research and Departure

Haku sought to prevent Orochimaru from sacrificing the Sound Village in a Konoha Crush operation. Under Haku’s guidance, Orochimaru abandoned that plan; he did not carry it out during the joint Chunin Exam 152 162 170.

Haku instead directed his research toward immortal natural-energy beings, including Moryo, Xuanming, and Goumang. Trusting Haku’s intelligence, Orochimaru declined to compete for the revived One-Tail and pursued these less-contested subjects 159.

His research eventually produced self-restraining energy seeds that could be surgically implanted into ordinary people, granting Genin-level strength. Delighted by the first successful batch, he intended to improve their performance further 172.

At the end of the story, Orochimaru expressed satisfaction with Bai’s growth and left with him to explore a new world, acknowledging Bai’s superiority regarding research subjects 198.

Personality

Orochimaru combines a cold manner with genuine attachment to selected people. Haku’s resilience evokes memories of Nawaki, and his voice softens when discussing Tsunade’s condition. His concern does not prevent him from treating Haku as a valuable experimental subject 30 40 97.

His bitterness toward Konoha’s leadership coexists with love for the village itself. He is ruthless toward expendable subordinates, amused by political disorder, and intensely excited by successful research. Nevertheless, Haku can redirect his priorities, including persuading him to abandon the Konoha Crush plan 44 138 162 172.

Abilities & Skills

Medical Research and Surgery

• Performs Haku’s Sharingan transplant and conducts postoperative examinations 40.
• Studies the relationship between cellular activity, injury, and recovery 30.
• Collects data on transplanted Sharingan, including emotional effects and chakra consumption 40.
• Secures advanced medical scrolls for Haku, though the context does not establish that he personally uses those techniques 30 36.

Natural-Energy Seed Engineering

• Develops self-restraining seeds from captured special beings’ energy 172.
• Surgically grants ordinary recipients strength comparable to a Genin 172.
• Enables the seeds to absorb matching energy from the air, replenishing their power rather than providing a single-use enhancement 172.
• Overcomes the initial problem of unmodified energy assimilating recipients and threatening their survival; the successful batch remains a preliminary result 172.

Combat and Command

• Uses a Shadow Clone during the team’s ambush test 14 15.
• Kills a Root ninja with a shuriken to the throat 44.
• Commands Konoha’s Kumogakure front and coordinates with the Nara clan leadership 22 32.

• Suspects Danzo’s involvement in unusual attacks around Konoha’s supply routes 31.
• Works on improving Root’s control seal while intending to preserve a backdoor for himself 44.
