Background / History

Early Experiments and Cooperation with Yato

Orochimaru initially conducts secret human experiments while cooperating with Shimura Danzō. Danzō supplies subjects and funding, expecting useful results; Orochimaru also hopes that their arrangement will help him become Fourth Hokage 37 162.

His early relationship with Yato is antagonistic. Yato discovers laboratories hidden beside Konoha’s toilets and ruins three of them. A confrontation nevertheless becomes the foundation of their partnership when Yato expresses interest in his scientific work instead of simply condemning it 7 36 37.

Yato challenges the assumption that possessing Wood Release automatically means possessing Hashirama Senju’s strength. Their discussions introduce the hypothesis that Wood Release combines water, earth, and yang chakra, and that Hashirama’s sage arts may help explain failed transplants. Orochimaru’s initial interest in taking Yato’s Sharingan gives way to genuine appreciation for his ideas 37.

Officially Sanctioned Research

Yato proposes involving Tsunade and Jiraiya in Wood Release research. Orochimaru hesitates over their cooperation, but accepts a medically framed approach and requests Yato’s participation because of his unusual bloodline 38.

Mito Uzumaki later inspects the laboratory and approves the project, explicitly requiring rational conduct and forbidding harm to participants. Her approval allows the research to become an official Konoha undertaking, with Yato providing funding rather than leaving Orochimaru dependent on Danzō 49.

This rehabilitation does not establish that his earlier work was harmless. Yato suspects Orochimaru and Danzō’s involvement in the deaths of orphaned experimental subjects, then plans to shift more of the evidence onto Danzō to finish clearing Orochimaru’s name 50.

Under the new arrangement, Orochimaru gains volunteers who are not treated as disposable subjects. His public reputation improves, and his demeanor becomes less gloomy. Yato still supplies prisoners and other experimental materials, while prohibiting indiscriminate killing—particularly within Konoha 122 162.

The Wager and Expanding Research

Yato introduces Dottore’s Segment as a possible route to immortality and proposes a duel: an Orochimaru victory earns a Sharingan or Mangekyō Sharingan, while a Yato victory requires one of Orochimaru’s clones to serve him. They travel to a remote island through Yato’s Anywhere Door 126.

The duel escalates from snake swarms and ambushes to giant transformations, Susanoo combat, and summoned beasts. Yato destroys the island’s terrain to eliminate Orochimaru’s hiding places. The Third Mizukage’s intervention turns the encounter into a three-way melee with shifting alliances 127 128 130 131.

Orochimaru subsequently works on Sharingan evolution, ocular-power replenishment, Impure World Reincarnation, and tailed-beast analysis. His Segment becomes a capable research partner, although being surpassed by it strains the original’s pride 161 162 262 305.

During the Third Shinobi World War, he maintains a laboratory inside his camp and continues experimenting despite the fighting outside. He also fights alongside Jiraiya, including an encounter with Chiyo and Sasori 320 343.

Parallel-World Counterpart

When Yato reaches another world, he finds an Orochimaru who has recently defected after Hiruzen Sarutobi discovered his forbidden experiments. Still dependent on Danzō, this counterpart lacks funding, materials, and new subordinates 408.

Yato shows him memories of their successful partnership in the original world through Sharingan genjutsu. Orochimaru tests him with a snake attack, only to be stopped and slapped through Yato’s time-manipulation ability. A letter from his happier counterpart then persuades him that cooperation could offer both better research and a better life 409 410.

Their partnership remains contentious. The counterpart passes a lethal Wood Release enhancement method to Danzō and Hiruzen, deliberately creating trouble for Yato. The information encourages Danzō to target the Uchiha; Yato later reveals that he had planted compatibility data in the research records to provoke this chain of events 443 445 479.

Yato eventually pushes him to confront his resentment toward Hiruzen and Konoha. Orochimaru complains that he was made to bear all responsibility for experiments whose subjects the leadership knew about, and that the Fourth Hokage position went to Minato. He accepts responsibility for preparing experiments and the Konoha Crush Plan 493.

Reunion and Later Collaboration

The parallel-world Orochimaru travels through a spacetime tunnel with Yato and Kabuto, then meets his original-world counterpart. Their meeting combines scientific curiosity with competing pride 521 522 524.

The two versions later cooperate in confronting Kakashi with information about Sakumo’s death and Konoha’s leadership. Meanwhile, the original and his Segment investigate the Senju–Uchiha connection and lead the research behind Yato’s Rinnegan awakening 530 593 595 637 663.

After settling into Yato’s world, the parallel counterpart grows to appreciate its lack of prejudice toward his work. Rather than retrieve Kabuto from the orphanage, he seeks information that will let him establish an independent research specialty 662 663.

Over the following four years, all three Orochimarus help Yato investigate unknown entities. Their experiments confirm that something external exists and produce measures intended to limit its influence and monitoring 676.

Appearance

• Voice: Hoarse yet somewhat rich; Yato recognizes him by it before he emerges from the shadows 36.
• Characteristic gesture: Frequently extends his tongue and licks his lips when intrigued, calculating, or excited 127 364 520.
• Contrasting demeanor: The original becomes elegant and easygoing under Yato’s influence, while the parallel-world counterpart retains a gloomy air 122 662.

Personality

Orochimaru is driven by the desire to understand life, acquire unfamiliar bloodline abilities, and achieve immortality. He particularly values collaborators who understand the pleasure of discovery. Yato’s willingness to offer hypotheses, resources, and practical solutions earns greater trust than Danzō’s results-oriented sponsorship 37 125 162.

His curiosity coexists with pride, greed, and suspicion. He openly covets the Mangekyō Sharingan, resents being outperformed by his Segment, and refuses to place himself casually in the position of an experimental subject. In battle, he is decisive enough to abandon an unfavorable position and switch to ambushes rather than persist with a losing exchange 127 161 521.

Yato’s influence makes the original’s experiments more controlled, but does not end them. The parallel counterpart is more willing to manipulate others, test allies, and weaponize dangerous findings. His jealousy of his happier alternate self also exposes a desire for companionship and recognition beyond scientific achievement 364 409 410 443.
