Background / History

Early forbidden research

Kaedeji infers that Orochimaru and Danzo have already joined forces during the period surrounding Konoha’s preparations for large-scale Hashirama Cells experiments. Their partnership rests on mutual usefulness rather than trust: Orochimaru’s research, strength, and survival abilities make him difficult for Danzo to control 9 41 61.

The Third Hokage notices a change in Orochimaru’s personality after Nawaki’s death. He nevertheless initially regards Orochimaru’s invitation to Kaedeji as tolerable research activity, rather than a warning of possible defection 78.

Front-line command and partnership with Kaedeji

As Konoha’s commander against Iwagakure, Orochimaru conducts surprise attacks targeting the Explosion Unit. He kills more than a dozen Explosion Release users over several years and takes some of their bodies for bloodline research 73.

One assault kills over five hundred enemy ninja at the cost of more than three hundred of his own. He refuses Senju Touka’s request for an immediate follow-up attack, recognizing both her anxiety over the Uchiha Clan’s achievements and the approaching end of the war 75.

Kaedeji’s ability to manipulate life, death, and vitality attracts Orochimaru’s intense interest. He invites Kaedeji into his human-experimentation project and requests his Eight Gates Technique, but Kaedeji refuses to teach it and warns that others would die attempting to use it 75 78.

Their cooperation expands into an attack on Blue B, Kumogakure’s unstable Eight-Tails jinchūriki. Orochimaru supplies intelligence and fights alongside Kaedeji’s corpses, but cannot reliably suppress the fully transformed Eight-Tails. Afterward, the Third Hokage reprimands him for taking Kaedeji on the unauthorized operation without imposing further punishment 88 90.

Hashirama Cells experiments and loss of support

Orochimaru leads the Hashirama Cells transplantation project, while Kaedeji provides a safety net through Corpse Manipulation. Senju Touka gains limited Wood Release, but other participants die or undergo uncontrolled tree-like transformation. Continued experiments on Senju volunteers produce high mortality 99 100.

His attempt to control a reanimated Kaedeji also fails. Kaedeji breaks the technique’s control, while Orochimaru and Danzo subsequently become entangled in attacks on the Akatsuki. Orochimaru narrowly survives Nagato’s soul-extraction abilities 103 104 106.

The Third Hokage confronts him over Kaedeji’s reanimation and the attack on Sunagakure’s One-Tails jinchūriki. Kaedeji’s return in a living, Wood Release–capable body disproves the assumption that Orochimaru still controls him; Kaedeji then declares their cooperation temporarily finished because Orochimaru has nothing further to offer 112.

Orochimaru joins Root’s invasion of Sunagakure in pursuit of One’s Own Life Reincarnation. When the Third Hokage suspends his human-experimentation project, he resolves to continue researching secretly 119 120.

Jigen’s collaborator

Orochimaru is appointed Hokage during Konoha’s later mobilization, though Kaedeji manages the large-scale troop movements. He also probes Obito’s unusual abilities, without obtaining a useful response 147.

Jigen approaches him on the Iwagakure front and reveals his identity as Ōtsutsuki Isshiki. Orochimaru agrees to cultivate a reincarnation vessel in exchange for knowledge, while privately rejecting the idea of becoming Jigen’s puppet 174 175.

He accelerates Konoha’s offensive, contributes to Iwagakure’s collapse, and returns to vessel research. Using Hashirama Cells and Hyūga genes, he cultivates Tenzō. Kaedeji rewards his work with Living Corpse Reincarnation but warns him against concealing his activities 177 178.

Orochimaru later discovers that Karma cannot absorb Natural Energy. Jigen’s resistance to a Sage Mode–capable vessel exposes a vulnerability that Orochimaru intends to exploit, even as he requests genuine Ōtsutsuki genes for further experiments 199.

Death, resurrection, and Kara research

During the attack on Mount Myōboku, Jigen abandons Orochimaru when retreating. Orochimaru tries to kill Nagato by exploiting Shinra Tensei’s five-second interval, but Nagato overwhelms his barrier and destroys his body 227 230 231.

Mizuki resurrects him in Konoha. Orochimaru rewards him with a Rashomon summoning contract, escapes after Iruka discovers them, and introduces Mizuki to Kara as an Outer member 236.

His subsequent work includes Shibai gene transplantation, the creation of Shinjutsu users, and participation in the birth of Divine Tree People. Mushi’s strength overwhelms both him and Tenzō, demonstrating the danger posed by creations they cannot control 251 252 263.

Betrayal of Isshiki and later work

Orochimaru retreats with Dodai when Madara and Hashirama attack Jigen’s base. He later activates Cursed Seals hidden in Tenzō, disrupting Isshiki’s resurrection with Sage Chakra that the Ōtsutsuki cannot directly absorb. Kaedeji’s surveillance pressures him into using this contingency 282 285.

He subsequently tells Kabuto that he intends to cultivate an Ōtsutsuki-bloodline body for himself; the supplied account does not establish that he succeeds. By the later reconstruction era, he walks openly through Konoha and invites Kabuto to help develop a vaccine against the Zombie Virus 290 309.

Appearance

Orochimaru’s documented distinguishing traits are strongly serpentine, extending from his eyes and tongue to the movement and shape of his modified body 75 77 88 177.

• Vertical pupils: He watches Kaedeji’s movements closely through slit-like eyes 88.
• Extendable tongue: His tongue stretches roughly half a meter out of his mouth when his excitement over Kaedeji becomes overwhelming 75.
• Snake-like flexibility: He slithers, slides away from attacks, and can elongate his body more than ten meters 77 177.

Personality

Orochimaru treats people and alliances according to their value to his research. He cooperates with Danzo, Kaedeji, and Jigen while remaining alert to their weaknesses, and explicitly rejects the claim that his work for Jigen ever constituted loyalty 61 175 236 285.

Immortality is his central ambition. Kaedeji’s casual treatment of eternal life provokes jealousy, while reincarnation vessels, Ōtsutsuki genetics, and the Ten-Tails’ biology excite him as opportunities to overcome his own limitations 87 174 199 200 263.

His scientific pride coexists with ruthless experimentation. He shows no remorse over transplant deaths, yet remains capable of meticulous surgical preparation and sustained technical refinement. Mizuki’s successful modification requires thousands of adjustments after the initial transplant 100 175 251.

In combat, he is calculating rather than passive. Even when escape appears impossible, he seeks a way to kill his opponent or destroy something valuable, as shown by his attempt to eliminate Nagato and his Rinnegan before dying 231.

Abilities & Skills

Biological Research and Genetic Engineering

• Hashirama Cells transplantation: Leads surgeries intended to grant Wood Release. Aggressive cell growth causes fatal transformations, and Touka’s survival depends on Kaedeji’s stabilization 99 100.
• Vessel cultivation: Produces Tenzō using Hashirama Cells and Hyūga genes for Isshiki’s reincarnation 178.
• Shibai gene research: Successfully modifies Mizuki to use Claw Marks and gives Dodai the ability called “Kill Intent Reversal” 251 252 282.
• Experimental limitations: Dodai suffers weakness and pain from the modifications; Orochimaru admits that his understanding of Shinjutsu remains incomplete 251 282.
• Divine Tree research: Participates in creating Divine Tree People and investigates their relationship to the Rinnegan and Ōtsutsuki 259 263.
• Virology: Proposes a Zombie Virus vaccine project with Kabuto 309.

Body Modification and Replacement

• Flexible physique: Uses snake-like movement and extreme elongation to evade attacks, including Ōnoki’s Dust Release 77 177.
• Great Serpent Style Body Replacement: Leaves an empty shell and escapes underground before the Demonic Statue’s soul-sealing dragon reaches him 104.
• Soul-attack limitation: His evasive methods do not make him immune to soul extraction; a timely Shadow Clone saves him from Nagato’s instant head-touching attack 106.

Snake Techniques

• Hidden Shadow Snake Hands: Releases venomous snakes from his sleeves to seize or attack a target 88 174.
• Many Snake Array: Expels an enormous mass of snakes from his mouth, using them to crowd the battlefield and prepare a follow-up trap 231.
• Large summons: Deploys two enormous snake-like creatures during the invasion of Sunagakure 119.
• Limits: His snakes cannot bite through Blue B’s Tailed Beast Cloak, and Jigen destroys them without injury 88 174.

Rashomon Summoning

• Single Rashomon: Blocks the partially transformed Five-Tails jinchūriki’s incomplete Tailed Beast Bomb 76.
• Triple Rashomon: Summons three demonic-faced gates; uses them as falling projectiles to briefly restrain the Eight-Tails 88.
• Limits: The successful restraint does not give him a reliable way to defeat or seal the Eight-Tails alone 88.

Reanimation and Reincarnation

• Impure World Reincarnation: Reanimates Kaedeji using a specially improved version, but loses control when Kaedeji reverses the hand seals 103.
• One’s Own Life Reincarnation: Obtains the complete technique from Kaedeji, resolving his concern over bodily lifespan 199.
• Living Corpse Reincarnation: Receives Kaedeji’s perfected technique and continues developing a Natural Energy–based Cursed Seal route for transferring his soul into another body 178 199.
• Cursed Seal resurrection: Stores soul fragments for revival; Mizuki provides the vessel for his return after Nagato kills him 236 285.

Barriers and Tactical Analysis

• Four Black Snake Formation: Traps Nagato inside a barrier with poisonous fog after provoking Shinra Tensei 231.
• Timing analysis: Exploits the five-second interval before Nagato can reuse the technique, though a higher-output Shinra Tensei destroys the formation 231.
• Natural Energy deduction: Uses Jigen’s responses to establish Karma’s inability to absorb Natural Energy, then turns this knowledge against Isshiki through Tenzō’s Cursed Seals 199 285.

Equipment / Weapons / Items

• Surgical tools: Uses scalpels and other laboratory equipment to dissect corpses, remove organs, and perform genetic transplants 88 174 251.
• Preserved biological specimens: Collects organs and prioritizes bodies carrying bloodline limits as research material 73 88 174.
• Rashomon contract scroll: Gives Mizuki a summoning contract as payment for resurrecting him 236.
• Sword of Totsuka — sought, not acquired: Searches for the legendary blade because of its ability to seal a pierced target’s soul 105.

Relationships

• Kaedeji — Research partner, coveted source of immortality techniques, and a recurring threat. Kaedeji ends their initial cooperation after obtaining his desired body, later rewards Orochimaru’s vessel research, and pressures him into sabotaging Isshiki 75 112 178 285.
• Danzo — Transactional ally who provides access to research opportunities and clan power. Both remain ready to exploit the other’s weakness; Orochimaru spares a vulnerable Danzo because he still has value 41 61 105.
• Sarutobi Hiruzen — Teacher and authority figure. Initially tolerant, he becomes furious over Kaedeji’s reanimation and ultimately suspends Orochimaru’s human-experimentation project 78 112 120.
• Jigen / Isshiki Ōtsutsuki — Supplies extraterrestrial knowledge and genetic material in exchange for reincarnation vessels. Orochimaru never accepts genuine subservience and sabotages his resurrection 175 199 285.
• Senju Touka — Front-line subordinate and Hashirama Cells test subject; Orochimaru performs the transplant that grants her unstable Wood Release 75 99 100.
• Jiraiya — Objects to the transplant experiments and later tries to reason with Orochimaru while held captive by Kara. Orochimaru instead intends to use him to create a Divine Tree Person 99 236.
• Nagato — Enemy whose Rinnegan attracts his interest. Nagato nearly extracts his soul in an earlier encounter and later destroys his body at Mount Myōboku 106 231.
• Mizuki — Secret subordinate and resurrection vessel. Orochimaru brings him into Kara and modifies him into a Claw Marks user 236 251 252.
• Tenzō — Cultivated vessel for Isshiki and the bearer of Orochimaru’s hidden Cursed Seal contingency 178 285.
• Dodai — Genetic test subject and escape companion; gains “Kill Intent Reversal” but suffers substantial side effects 282 285.
• Yakushi Kabuto — Loyal subordinate and later prospective vaccine-research collaborator 290 309.

Notable Quotes

“Killing someone’s parents was already wrong. Failing to eliminate him afterward was an even greater mistake.” 112

“We have never offered loyalty to that Otsutsuki. Every decision that follows is merely justified action driven by personal interests.” 285

Trivia

• Despite his actions against Konoha’s interests, he has not formally been designated a rogue ninja when Iruka discovers his association with Mizuki 236.
• He shows little interest in the Hokage position during his earlier dealings with Danzo, yet is later appointed Hokage without objection 41 147.
• His goal of acquiring an Ōtsutsuki-bloodline body is a stated plan, not a confirmed transformation in the supplied account 290.
