Background / History

Otogakure and forbidden research

Orochimaru leads Otogakure and maintains an intelligence network through Sound ninja and agents such as Kabuto Yakushi. His research includes Cursed Seals, body transplantation, souls, and Hashirama Senju’s cells. He also cooperates with Danzo on cellular modifications; Yamato is identified as a product of their years of research 44 55 74 110.

Chunin Exams and the Konoha Crush Plan

During the Forest of Death exam, Orochimaru approaches Team Seven disguised as Zaku. Sasuke is his original target, but Nanfeng’s chakra reserves, medical talent, and resistance to killing intent attract his attention. He overwhelms the team, poisons Naruto, and bites Sasuke to implant a Cursed Seal. He also injects Cursed Seal power into Nanfeng, although Nanfeng later claims that no seal activated 56 57 58 109.

Anko pursues him with Anbu support and attempts Twin Snakes Mutual Death. Orochimaru neutralizes the attack, incapacitates her through her Cursed Seal, and leaves a threat for the Third Hokage rather than killing her 58.

He subsequently poses as the Kazekage and uses a covert agent to test Sasuke during the exam. During the Konoha Crush Plan, he reveals himself to his former teacher, Hiruzen Sarutobi, and uses the Sound Ninja Trio as sacrifices for Impure World Reincarnation. The conflict ends with Hiruzen dead and Orochimaru’s hands crippled by soul damage 65 98 109.

Second battle with Nanfeng

Tsunade refuses to heal Orochimaru, explaining that medical ninjutsu cannot restore a stolen soul. Unable to form seals himself, he borrows Kabuto’s hands through a snake-mediated chakra connection 108 109.

Against Nanfeng, he reveals Sage Mode, escapes a prolonged lightning assault through a shedding substitution, and seizes the injured Tsunade. His use of a materialized clone conceals his true body’s position, allowing him to critically wound Nanfeng 110 111.

Sasuke’s recruitment and cooperation with Nanfeng

Following the battle, Orochimaru’s body deteriorates rapidly. Repeated body changes leave him weak, increasing his urgency to obtain Sasuke as a vessel. He dispatches Sound ninja and Kimimaro to retrieve Sasuke, who willingly agrees to leave Konoha 149 150.

Nanfeng negotiates for Orochimaru to train Sasuke, initially requesting that Sasuke become capable of defeating Itachi within three years. Their arrangement develops into medical treatment for Kimimaro in exchange for Sasuke’s training. Orochimaru’s interest in Nanfeng gradually shifts from acquiring a vessel to retaining a valuable research partner 151 152 164 165.

Their exchanges expand to Nanfeng’s unusual bloodlines and the Uzumaki origins of the Reaper Death Seal. Orochimaru concludes that Nanfeng’s body would decompose his soul if he tried to possess it, and begins considering cooperation with Nanfeng more valuable than his association with Danzo 168 169.

Staged death and return to Konoha

Nanfeng, Sasuke, Orochimaru, and Kabuto prepare a staged master-disciple betrayal around Orochimaru’s body-transfer procedure. News then spreads that Sasuke has killed him. In reality, Orochimaru appears openly in the Hokage’s office and adopts Sanyue Shang, a newly promoted Konoha jonin, as his new identity 228 229.

He explains that repeated transplantation has damaged his soul and reduced his resistance to genjutsu almost to zero. The Sharingan cannot repair that damage, prompting him to pursue different approaches to immortality. His agreements with Konoha include intelligence on Danzo and contributions to new ninjutsu research 229.

Orochimaru later attributes his return to Nanfeng’s friendship and respect. His new working conditions permit experiments on dangerous criminals and rogue ninja, an arrangement he credits with improving public safety around Konoha 363.

Kabuto’s betrayal and the Ninja World War

Kabuto evades Orochimaru’s control by splitting his soul into independent parts. His secret cooperation with Danzo and interference in Sasuke’s battle expose the limits of Orochimaru’s safeguards. Orochimaru admits that his former subordinate’s betrayal was unexpected and begins developing new tracking methods 243 252 255 259.

During the war, Orochimaru intervenes against Kabuto’s reanimated Fugaku and Mikoto Uchiha. He supplies Itachi with a sealing scroll, then confronts Kabuto directly. Working with the Uchiha brothers, he eventually controls Kabuto’s soul and seals his abilities 350 360 361.

He then revives the four former Hokages using cloned White Zetsu as sacrifices. The Fourth Hokage’s return is also intended to restore the Nine-Tails to its complete form. Orochimaru later contacts Nanfeng in the Pure Land and expresses surprise that Nanfeng entered it with his physical body 361 371.

Later medical and technological work

Orochimaru takes Neji away from the battlefield because conditions there cannot support eye-transplant surgery. At one of his strongholds, he transplants special Byakugan into Neji’s empty sockets to restore his sight, with the stated cost of halving Neji’s lifespan 437 438.

His later research turns toward combining machinery and ninjutsu. Repeated errors and laboratory explosions reveal that this field remains difficult for him; he welcomes the Queen of Roran’s planned assistance with further development 495.

Appearance

• Feminine facial features and narrow eyes: His exposed face carries an eerie smile during the Forest of Death encounter 56 109.
• Sharp fangs: Uses them to bite Sasuke’s neck and implant a Cursed Seal 57.
• Signature tongue gesture: Anko recognizes him partly through this familiar mannerism after his staged death 229.
• Flood-dragon-like Sage form: Possesses a tail capable of coiling around and restraining Tsunade 110.
• Later altered form: Resembles Kabuto’s modified appearance but is less grotesque and retains a roughly human outline 350.
• Variable host appearance: Chooses attractive bodies of either sex for transplantation 108.

Personality

Orochimaru initially treats opponents as both prey and potential research material. He enjoys prolonging unequal fights, provokes Sasuke through references to Itachi, and taunts Anko about her role in his early experiments. His interest intensifies when he encounters abilities he cannot immediately explain 56 57 58 110.

His pursuit of knowledge is systematic rather than merely speculative: he supports unusual ideas with theory, experimentation, and verification. Research matters more to him than political office. He rejects the Hokage position because its duties would consume his time and its salary would not adequately fund his equipment 361 366.

Cooperation with Nanfeng gives him reasons to value friendship alongside profit. He warns Nanfeng against assuming that their dealings reveal his entire character, yet later identifies respect and friendship as conditions for returning to Konoha. This change does not end his use of human experimental subjects 165 363.

He can acknowledge another researcher’s achievements, including Kabuto’s advances beyond his own work. Their later rivalry reflects diverging goals: Orochimaru prioritizes continued existence and immortality, while Kabuto seeks the world’s underlying truth 350.

Sage Mode

• Transformation: Assumes a flood-dragon-like state that produces overwhelming pressure 110.

• Continued development: His later form demonstrates further bodily evolution during the war 350.

Cursed Seals

Orochimaru develops the Cursed Seal as a source of power, influence, and spiritual continuity 58 109 229.

• Power enhancement: Grants Sasuke heightened strength, accompanied by aggression, bloodlust, and unstable chakra 57 62.
• Mental influence: Allows Orochimaru to sense aspects of Sasuke’s thoughts and presence and encourages his transformation into a suitable vessel 149.

• Communication medium: Nanfeng uses Kimimaro’s seal to establish long-distance chakra communication with Orochimaru 151 152.
• Removal: Orochimaru causes Anko’s seal to dissipate through physical contact after returning to Konoha 230.
• Limits: Sasuke’s strengthened will resists his spiritual and chakra-based temptation; Nanfeng shows no visible seal activation despite receiving its power 58 109 149.

Body Transfer and Soul Research

• Body transplantation: Changes hosts to prolong his existence, but consecutive transfers can leave him severely weakened 149.
• Spiritual cost: Foreign bodies cause irreversible soul damage that the Sharingan cannot repair 229.
• Genjutsu vulnerability: Reports that his resistance has fallen almost to zero because of that damage 229.
• Incompatible vessel: Determines that Nanfeng’s altered body would decompose his soul rather than house it 168.
• Soul Probe: Enters a target’s spiritual space to uncover hidden information. Uses Nanfeng’s mental energy to investigate and remove Kabuto’s modified Reaper Death Seal from Anko 295.
