Background / History

Before defecting from Konoha, Orochimaru watched Itachi train and began coveting the Sharingan. After taking control of the Land of Rice’s daimyo, he established Otogakure as a base for village development and ninjutsu research. Over several years, he improved Tobirama Senju’s Impure World Reincarnation 35.

His partnership with the Uchiha began when Itachi and Shisui confronted him. Shisui used Kotoamatsukami, after which Orochimaru accepted their cooperation and prepared to research Itachi. Their initial confidence in submitting to his experiments depended on that genjutsu rather than ordinary trust 35 36.

Natsuki’s research notes redirected Orochimaru’s ambitions beyond obtaining the Sharingan. He investigated the relationship between bloodlines, bodily health, and ocular power, while Uchiha personnel helped develop Otogakure. Takuya took over administrative work, freeing Kabuto to assist in the laboratory 36 51.

Orochimaru later confronted Natsuki about the Kotoamatsukami manipulation. Natsuki admitted arranging it, but Orochimaru chose to continue their collaboration. Years afterward, he regarded Natsuki as his closest friend and recognized the trust and resources Natsuki had offered him even during his life as a rogue ninja 156 1172.

Appearance

• Voice and mannerisms: Has a hoarse yet magnetic voice and frequently extends his tongue or circles it around his face 35 197.
• Public presentation: Returns to Konoha with a scholarly, refined appearance and a courteous manner, contrasting with his usual sinister demeanor 214.
• Reincarnated body: Appears approximately four or five years old when meeting the reanimated Tobirama, and later resembles a boy of fourteen or fifteen 857 953.
• Serpent transformation: His Eight-Headed Serpent manifests enormous white snake heads and can regenerate severed heads 52.

Personality

Orochimaru values scientific discovery above office or prestige. His earlier resentment over losing the Fourth Hokage position arose from Hiruzen choosing Minato over him, not from a lasting obsession with governing. He describes truth as his lifelong pursuit and accepts the Hokage position primarily for access to materials, equipment, techniques, and researchers 99 299 471.

He is pragmatic about both cooperation and deception. He overlooks Natsuki’s use of Kotoamatsukami when their shared work remains advantageous, and he can apologize when doing so helps secure Tsunade’s medical expertise. Hiruzen considers him an extreme egoist whose willingness to work with any beneficial partner makes him difficult to control 156 551.

His research has few ethical restraints. He dissects the captive Urashiki while Tsunade heals the subject, and initially considers imprisoning the entire Sarutobi Clan as human-experimentation material. Natsuki persuades him to consider the practical value of maintaining a favorable reputation 560 694.

Despite this ruthlessness, he recognizes talent and maintains enduring personal bonds. He approves of Kabuto’s increasingly independent judgment, trains Keimei as an assistant, and appreciates Natsuki’s continued lack of arrogance even after becoming vastly stronger 154 207 1172.

Abilities & Skills

Biological Research and Genetic Engineering

• Bloodline analysis: Studies Sharingan evolution, Ōtsutsuki ancestry, and the pathological consequences of unstable Kekkei Genkai 36.
• Hashirama-cell research: Develops a cell solution and investigates separating cellular will from Hashirama’s cells. The solution’s success rate is initially very low 207 334 450.
• Perfect-vessel development: Creates an artificial body with all elemental affinities, Nature Affinity, and a restored Ōtsutsuki bloodline 753.
• Gene completion: Completes the Earth God Squad members’ genes; higher Sharingan levels subsequently accelerate their evolution 1090.
• Energy processing: Converts life energy and chakra harvested from Ninja Professional Leagues into usable energy for selected recipients 1196.
• Research limitation: Delicate laboratory work cannot simply be multiplied through Shadow Clones; the returning medical data would overwhelm the researcher and require days of recovery 36.

Medical Treatment and Cloning

• Itachi’s illness: Identifies the cellular damage associated with Mangekyō Sharingan use and keeps Itachi from becoming ill through excessive ocular development 36 207.
• Kimimaro’s condition: Develops medicine that suspends his growth, preventing an early death caused by Shikotsumyaku 207.
• Replacement eyes: Successfully performs Kakashi’s eye surgery using a clone, restoring his sight 299.
• Ocular limitation: Can clone Itachi’s remaining eyes, but initially guarantees only ordinary eyes—not that the replacements will awaken Sharingan 281.
• Limb restoration: His cloning technology saves ten jōnin in a short period, with further replacement limbs still being cultivated 336.
• Civilian access: Refinements steadily reduce costs until even civilians can potentially afford treatment for disabilities or terminal illnesses 694.

Reincarnation and Soul Preservation

• Body transfer: Previously reincarnates by using a white snake to seize another person’s consciousness 753.
• Stored will: Leaves part of his will inside Anko and later reabsorbs it to repair his soul 197.
• Artificial-body transfer: Uses a formation to compress his soul before merging with an embryo. Dan Katō completes the technique through Orochimaru’s discarded body while Tsunade supports development 753.
• Developmental limit: The new body initially has limited energy storage because of its small size 828.

Impure World Reincarnation and Resurrection Research

• Technique improvement: Refines Tobirama’s original Impure World Reincarnation over years of experimentation 35.
• Combat summons: In Natsuki’s dream training, summons Hashirama and Tobirama as powerful combatants 52 104.
• Personal reunions: Reanimates Rin for Kakashi and Sasori’s parents for a family reunion 432 743.
• Duration limit: Sets one week as the safe limit for Sasori’s parents to remain summoned without soul damage 744.
• Sacrifice quality: Considers ordinary White Zetsu inadequate for restoring Hashirama at sufficient strength and later replaces the sacrifices for both founding Hokage 917 953.
• Soul destruction: Adds a separate formation to the reanimation process that shreds Momoshiki’s soul before completing Minato’s summoning 1040.
• Living-body restoration: Creates bodies that bear the enormous life-force cost of converting reanimated people into living humans. This method depends on the Water of Life he obtained 1100.

Snake Techniques and Regeneration

• Summoning: Calls Manda and other snakes; also cultivates a Second Manda from the original’s genes 35 401.
• Eight-Headed Serpent Technique: Transforms into a huge multiheaded serpent whose severed heads repeatedly regenerate 52.
• Soft Physique Modification: Uses extreme bodily flexibility and unexpected snake attacks. These are among the techniques that repeatedly defeat Natsuki in dream training 52.
• Evasion: Twists into different shapes, becomes a snake, and uses substitution to escape Danzo’s rampaging Wood Release 399.
• Tactical limitation: Avoids the Eight-Headed Serpent against Danzo because he wants to capture him alive for research 401.

Poison and Forbidden Techniques

• Mixed poison: Uses snake venom and blood that combine into a subtle airborne poison during the Urashiki battle 557 558.
• Cumulative effect: Urashiki’s repeated time rewinding causes the poison to accumulate until he collapses, allowing Orochimaru to remove his eyes 558.
• Environmental limitation: The poison takes longer to act when the battlefield is insufficiently enclosed 558.
• Information security: His expertise in curses and forbidden techniques helps prevent employees from revealing the Uchiha Clan’s culinary secrets 155.

Elemental Ninjutsu

• Nature transformations: Has mastered every nature transformation, rather than relying exclusively on snake techniques 403.
• Wind Release: Great Breakthrough: Uses deeply developed mastery of the technique to spread flames across Danzo’s flowering forest 403.
• Water Release: Water Colliding Wave: Combines his water stream with Jiraiya’s and summoned toads’ attacks to extinguish returning flames 403.

Rinnegan and Ōtsutsuki Countermeasures

• Foresight: Uses blue Rinnegan to anticipate attacks and match Urashiki’s future predictions 1013 1067.
• Experimental reenactment: Rewinds or reenacts experiments to reduce wasted time and preserve precious materials 828 1091.
• Prepared bodily control: Immobilizes Isshiki inside the stolen Urashiki body through hand seals, causing burning pain and weakness 1013.
• Technical intelligence: Obtains fragments of Isshiki’s memories, chiefly technical knowledge; they provide little recent information about the wider Ōtsutsuki Clan 1069.
• Unconfirmed advancement: Natsuki still asks when Orochimaru will advance to Kekkei Mōra. His compatible body and ability to store that energy do not establish that he has attained the realm himself 1091.

Equipment / Weapons / Items

• Kusanagi Swords — Possesses multiple swords and produces them through his mouth or a snake. Gives Natsuki a smaller sword intended for Sasuke 100 401.
• Urashiki’s fishing rod and fish basket — Keeps the defeated Urashiki’s equipment. The basket absorbs and strengthens an incoming Heavenly Wave Meteor Life attack before reflecting it; energy it has already consumed cannot be consumed again 1067.
• Laboratories and cultivation equipment — Uses cloning facilities, an embryo cultivation device, and advanced instruments obtained through the Hokage’s office 471 753.
• Reaper Death Seal Release — Supplies the release technique to Natsuki 197.
• Chimera Technique research material — Uses the technique acquired through Kakuzu as a reference and source of new ideas 723 754.

Relationships

• Natsuki Uchiha — Research partner, political collaborator, and eventually closest friend. Their alliance survives the revelation that Natsuki arranged Kotoamatsukami against him 156 423 1172.
• Kabuto Yakushi — Trusted assistant and eventual Sound Shadow. Kabuto regards Orochimaru as superior, brother, and family, and guards his reincarnation procedure in Sage Mode 36 99 753.
• Itachi Uchiha — Initially an object of Sharingan envy, then a cooperative research subject whose health Orochimaru maintains 35 36 207.
• Shisui Uchiha — Uses Kotoamatsukami on him and subsequently participates in Mangekyō stabilization research 35 36.
• Keimei Uchiha — Talented laboratory assistant. Orochimaru trains him and entrusts him with Hashirama-cell experiments and data collection 207 334.
• Tsunade — Former teammate and major medical collaborator. Their joint work includes studying Urashiki and supporting Orochimaru’s artificial-body reincarnation 551 560 753.
• Dan Katō — Assists the soul-transfer procedure by occupying Orochimaru’s discarded body and completing the necessary seals 753.
• Hiruzen Sarutobi — Former mentor and political sponsor. Orochimaru resents being passed over for Minato but later accepts Hiruzen’s offer of the Hokage position 99 299.
• Jiraiya — Longtime teammate and intermediary with Konoha. Their combat coordination remains effective, though Orochimaru later excludes him from the central research plan 92 401 686.
• Anko Mitarashi — Student in whom he stored part of his will. She eventually resumes addressing him as her teacher and carries out surveillance orders for him 197 214 733.
• Kakashi Hatake — Patient and loyal subordinate. Restoring his sight and reanimating Rin earn Kakashi’s wholehearted allegiance 299 432.
• Minato Namikaze — Collaborator and administrative support. Handles village affairs so Orochimaru can concentrate on research 471 857.
• Kimimaro and Haku — Young followers whom Orochimaru teaches alongside his research responsibilities; both accompany his return to Konoha 207 214.
• Sarutobi Clan — Initially favored and recalled into village departments, then trapped through debt, investigations, and restricted opportunities 592 617 675 733.

Story Role / Major Arcs

Return to Konoha and Hokage Election

Natsuki proposes making Orochimaru Hokage so that Konoha’s resources can accelerate his research. Hiruzen later clears Orochimaru’s name, and Orochimaru returns openly with Kimimaro, Haku, Jugo, Karin, and another child 99 178 214.

His cloning treatments build public credibility. Hiruzen offers him the position with access to secret techniques, resources, and an experimental team; Orochimaru agrees on the condition that Hiruzen initially handles official duties. He is elected Fifth Hokage after Natsuki exposes irregularities involving the Sarutobi Clan’s jōnin 299 336 341.

Although publicly presented as Natsuki’s political rival, Orochimaru has remained his ally. Tsunade and Jiraiya separately discover that Natsuki arranged his return and helped engineer his rise to power 423 446.

Governance and the Sarutobi Trap

Orochimaru uses vacant Advisor Elder positions to strengthen ties with the Nara and Hyuga clans. He protects the former advisers from immediate investigation and refuses scrutiny of Sarutobi Anbu identities on confidentiality grounds 358 360.

He recalls Sarutobi personnel, distributes posts and missions to them, and discovers that the clan possesses more than three thousand ninja. Loans for purchasing Kushina’s properties create a financial trap; he then coordinates investigations while deliberately leaving the clan’s strongest Anbu branch free to act under surveillance 592 617 674 675 684 733.

Urashiki’s Capture and Research

Orochimaru and Natsuki prepare countermeasures against the arriving Urashiki, including toxins and restrictions on escape. Orochimaru’s mixed poison ultimately incapacitates him, and Orochimaru removes his eyes 550 558.

The captive becomes a major research subject. Orochimaru conducts live dissections while Tsunade heals him, with Kabuto and Keimei joining the study of differences between humans and Ōtsutsuki 560.

Spear of Heaven Incident

Orochimaru examines the Spear of Heaven and identifies its uncontrolled absorption of underground energy as a threat capable of desertifying neighboring regions. Initially more interested in collecting data than fighting Obito, he intervenes when Natsuki asks him to restrain the regenerating Eight-Headed Black Snake 640 641.

Afterward, he plans to dismantle and study the weapon’s base 649.

Artificial Reincarnation and Later Research

With Tsunade, Dan, Kabuto, and other safeguards in place, Orochimaru successfully transfers his soul into his artificial embryo. During Jigen’s later attack on the laboratory, Tsunade evacuates the young Orochimaru while Dan controls Urashiki’s body 752 753 822.

He continues supporting both warfare and reconstruction: preparing Yang Release chakra to replenish Uchiha ocular power, improving resurrection bodies, developing seawater-to-freshwater technology with Cloud Village, and allocating bloodline upgrades according to expected combat benefit 953 1100 1152 1248.
