Background / History

Orochimaru had just returned from an S-rank mission when Hiruzen Sarutobi brought him to meet Xuanhui, whom Hiruzen considered exceptionally promising. Though initially distant, Orochimaru helped Hiruzen teach the child chakra extraction and agreed to supervise his training for the morning. 3

At Ichiraku Ramen, Xuanhui's views on the meaning of life and his desire to pursue knowledge resonated with Orochimaru's own reflections on life’s fragility. Orochimaru accepted Xuanhui as his disciple after asking whether he truly had the resolve to become a ninja. 4

Xuanhui later introduced Orochimaru to a vast library containing modern scientific books. Fascinated by subjects including molecular biology and physics, Orochimaru began staying in the library to study and claimed Xuanhui as his disciple in front of Hiruzen. 5 15

After Xuanhui graduated, Orochimaru became his jōnin squad leader so that he would only need to lead Xuanhui rather than a full genin team. He took his disciple on increasingly dangerous missions, including an A-rank merchant escort that brought them into conflict with Kakuzu. 10 19 23

During the war against Hidden Rain, Orochimaru served alongside Jiraiya and Tsunade. He trusted Xuanhui with intelligence work concerning Hanzo's poison, coordinated Konoha's counterattack, and worked with Tsunade to develop a toxin and antidote based on acquired enemy material. 34 35 36 37 38

Following the conflict, Orochimaru requested access to Konoha's complete collection of forbidden techniques, stating that he wished to improve the incomplete jutsu left by earlier generations. Hiruzen refused unrestricted access but offered to let him learn individual techniques. 47

Orochimaru's subsequent Hashirama-cell research produced a successful treatment for Senju Nawaki. After Nawaki survived the dangerous restoration of the cells' vitality, Orochimaru planned a Hashirama-cell prosthetic limb that would allow him to use Wood Release. Hiruzen stopped further testing because of its risks, and both men reassured Nawaki after Danzō unsuccessfully demanded that Root take custody of him. 63

Danzō later attempted to restart Hashirama-cell experiments using infants, threatening Orochimaru's funding and offering the Forbidden Techniques Compendium as an inducement. Orochimaru refused and drove him away with venomous snakes. He explained that becoming a missing-nin through endangering lives would prevent him from openly conducting experiments with Xuanhui. 64

After observing Xuanhui's expanding abilities, Orochimaru declared that his disciple was ready to graduate from his instruction. The two made a wager: if Xuanhui ended the war within a year, Orochimaru would travel the shinobi world with him; otherwise, Xuanhui would surrender his accumulated money. Following the peace treaty, Hiruzen approved their journey. 69 75

Their travels began with an expedition to the Uzumaki ruins and eventually included Kakuzu as a companion. Orochimaru helped uncover sealing techniques, acquired the Kusanagi Sword in the Land of Iron, received Takigakure's secret techniques, and examined the biological effects of Xuanhui's Light Release Chakra Mode. He also treated an abused Uzumaki couple in the Land of Grass. After seven or eight months, he and Xuanhui returned to Konoha with new techniques, artifacts, and research materials. 76 78 86 89 92 96

Orochimaru continued laboratory research with Xuanhui and took part in the Third Shinobi World War. He deployed to the Iwagakure front with experimental equipment, temporarily guarded the eastern front alongside Kakuzu, and later informed Xuanhui that Iwagakure had accepted a ceasefire, leaving Hidden Mist as the remaining opponent. 105 123 128 151

After the war, Xuanhui supplied him with a copied Forbidden Techniques Compendium and arranged his infiltration of Amegakure. Orochimaru fought Danzō and Hanzo alongside Kakuzu and the future Akatsuki leadership, then joined the organization as a researcher. His farewell letter to Hiruzen claimed responsibility for Danzō's assassination and identified Xuanhui as his secret intelligence contact. Hiruzen reluctantly accepted the undercover arrangement and had Orochimaru listed as missing. 161 163 164 166 167 168

Within the Akatsuki, Orochimaru gained access to White Zetsu as artificial substitutes for human test subjects. He improved Obito's compatibility with Hashirama cells, studied reincarnation techniques, transferred himself into a White Zetsu body, and developed cell-engineering methods that strengthened the organization's members. His research expanded to artificial tailed beasts and the biology of the Ōtsutsuki. 173 175 183 201 239

Orochimaru eventually ended his undercover assignment and returned to Konoha with the rescued Gaara and Fū. In public, he explained his disappearance as imprisonment by a hidden sealing technique in Kirigakure's ancient ruins, from which Xuanhui had rescued him. Minato knew the actual undercover circumstances and restored his normal Konoha registration. Orochimaru reunited with Hiruzen, Tsunade, and Dan, while remaining focused on research rather than accepting another squad. 287 288

During preparations for the next great war, Orochimaru joined the jinchūriki protection squad, produced miniature Eight-Tails and Nine-Tails, and covertly supplied them to Obito's side as part of the larger plan. He later coordinated the return of the researchers on the moon, performed the eye transplants needed for Sasuke's advancement, and joined the assembled allies. Kaguya subsequently transported him, Xuanhui, Naruto, Sasuke, Kakashi, and Obito into her dimensions, where he provided support during their efforts to counter her attacks. 297 298 300 301 308 317 319 320 333 334

Appearance

Orochimaru is a pale-skinned man with an unnervingly cold presence and a slightly hoarse voice. 3

• Vertical pupils and narrow, half-lidded eyes. 3
• Long hair that can obscure his expression. 13
• Long, slender tongue. 4
• Often wears wide-sleeved robes. 3
• His eyes and smile are described by Xuanhui as intimidating. 11
• During his body-transfer procedure, a large snake resembling him emerges from his mouth and enters a White Zetsu, whose body changes into Orochimaru's appearance. 175
• Wears surgical gloves when carrying out the battlefield eye-transplant operation for Sasuke and Fugaku. 319

Personality

Orochimaru is calm, rational, and intensely driven by curiosity. He is especially drawn to unsolved mysteries, chakra theory, bloodline limits, anatomy, and scientific knowledge. The library's scientific texts immediately captivate him, and he regards research as an endless pursuit of learning. 5 30 38

He is blunt and often unnerving in his methods. He tests Xuanhui's vigilance by threatening him with a kunai while he sleeps, considers experimentation as a route to overcoming the Sharingan's drawbacks, and initially proposes killing Yahiko, Konan, and Nagato to spare them future suffering. 11 21 46

Xuanhui's influence gradually makes him more expressive, patient, and socially open. He teaches his disciple carefully, defends his place as Xuanhui's teacher, worries about Xuanhui while injured, and ultimately lowers his kunai after hearing Xuanhui defend the war orphans’ potential. 5 15 42 46

His ambition to master every technique is tied to his awareness of life's limits. During a candid conversation beneath the stars, he explains that he wants to live as long as possible so that he can continue discovering truths. At the same time, he recognizes Xuanhui's independence and accepts the prospect of traveling together rather than keeping him permanently under instruction. 69

Orochimaru's changing behavior is evident in his enjoyment of exploration and companionship. His discovery of the Kusanagi Sword produces unusually childlike excitement, and his time in the Land of Birds reveals a warmer curiosity about living creatures beyond their usefulness in immortality research. 86 92

His attachment to Xuanhui also affects his research choices. He refuses Danzō's proposal to experiment on infants because the consequences would separate him from openly working with his disciple. Later, he shows genuine concern for Kimimaro's recovery and praises Kabuto's medical skill, demonstrating that his scientific interests coexist with personal affection. 64 239

He remains possessive of his laboratory, impatient with interruptions, and capable of elaborate deception. He rejects the Akatsuki's Void ring because technical support suits him better than missions, devises a deliberately simple cover story for returning to Konoha, and angrily dismisses colleagues who praise his work but refuse to become experimental subjects. 239 250 258

His familiar teasing persists after years apart from Xuanhui. At their reunions, he complains about his disciple's infrequent visits and repeatedly asks whether Xuanhui and Pakura have children. During Naruto's Reverse Harem Technique against Kaguya, however, he calmly closes his eyes and states that he has no interest in watching. 214 244 287 335

• Studies modern books on biology, chemistry, and physics supplied through Xuanhui’s library. 5
• Explains that bloodline limits depend on combining chakra natures in particular proportions while amplifying desired properties and reducing others. 32
• Recognizes Xuanhui’s proposed four-nature fusion as an undertaking comparable in difficulty to the Second Tsuchikage’s Dust Release. 32
• Analyzes the Sharingan’s evolution, its psychological trigger, and the costs of Mangekyo Sharingan use. 21
• Works with Tsunade to identify toxin components and develop countermeasures, while acknowledging that her medical chemistry knowledge exceeds his own. 37 38
• Identifies how Light Release Chakra Mode damages ordinary cells more severely but stimulates Xuanhui's Hashirama cells in a beneficial manner. 89
• Collects and investigates secret techniques from other villages, including Takigakure's collection, and studies forbidden techniques supplied by Xuanhui. 89 96 105 161
• Works with Xuanhui on genetic engineering and contributes substantially to Konoha's technological development. 105 235
• Studies White Zetsu in light of information about Kaguya, Isshiki, and future Ōtsutsuki threats shown to him by Xuanhui. His research interests consequently extend beyond terrestrial life. 201
• Collaborates with the revived Senju brothers on the Ōtsutsuki and methods of opposing them, using materials including Hamura's remains. 216 219 288

Tactical Leadership

Orochimaru is an observant and strategically minded battlefield commander.

• Detects a follower during the caravan mission and urges Xuanhui to expand his sensing range. 11
• Prioritizes mission efficiency and rapid travel to reduce risks to protected clients. 11
• Recognizes the danger in Hidden Rain’s likely strategy after considering Xuanhui’s analysis of Hanzo’s intended war of attrition and annihilation campaign. 32

• Guards the eastern front with Kakuzu at Xuanhui's request during the Third Shinobi World War. 128
• Coordinates the moon researchers' return by reporting the Allied Shinobi Forces' mobilization, Madara's approaching revival, and the locations of the living and reanimated Kage. 308

Chakra Natures and Sealing Analysis

Orochimaru possesses all five elemental chakra natures as well as Yin and Yang. At the Uzumaki ruins, Xuanhui relies on him to supply natures that Xuanhui has not yet mastered. 78

• Applies Wind, Lightning, Earth, Water, Fire, Yin, and Yang chakra in a prescribed sequence to dismantle the Uzumaki Great Path Seal. 78
• Works with Xuanhui's ocular analysis to identify and break the seal's shifting focal points across its nested layers. 78
• Uses attacks from all five elemental releases when testing Light Release Chakra Mode; Xuanhui's mode dissolves each attack. 89
• Explains the tactical applications of changing density, including flight, increased speed, and stronger impacts after acceleration. 90

Snake Ninjutsu and Transformation

Orochimaru specializes in snake techniques, using snakes for direct attacks, restraint, medical procedures, intimidation, and covert communication. 64 105 163 239 301

• Many Snake Formation — Expels tens of thousands of venomous snakes from his mouth to attack Danzō's forces. 163
• Eight Branches Technique — Transforms into an enormous Eight-Headed Serpent and coils around Hanzo's salamander, Ibuse. The technique leaves him sweating and significantly strained afterward. 164 166
• Uses snakes to anchor Kakuzu during Xuanhui's descent into the concealed well containing the Kusanagi Sword. 86
• Employs anesthetic snake venom during Kimimaro's operation and removes its effect after the procedure succeeds. 239
• Conceals a scroll carrying miniature tailed beasts inside a black snake and transfers it into Kamui through a staged confrontation with Obito. 301
• Uses a snake to hold Xuanhui during the group's escape from Kaguya's attack. 334

Swordsmanship and Equipment

Orochimaru has a longstanding interest in swordsmanship and the legendary Kusanagi Sword. He persuades his traveling companions to search for it and keeps the sword after Xuanhui retrieves it from a concealed well. Its reputed unbreakability makes it a particularly prized acquisition. 86

• Displays the Kusanagi Sword to Hiruzen after returning from his journey. 96
• Develops or shares chakra-battery technology, which Sasori installs in his puppets so that they can use and recover chakra like ordinary ninja. 285

Medical Ninjutsu and Transplantation

Orochimaru performs precise surgery using chakra blades, prepared tissue fluids, and modified cells. His procedures range from prosthetic construction to eye transplantation and the treatment of hereditary illness. 63 239 319

• Restores vitality to Hashirama cells in Nawaki and prepares a compatible prosthetic limb. 63
• Coordinates Xuanhui's eye-operation details with Tsunade. 67
• Treats the injured Uzumaki couple rescued in the Land of Grass. 92
• Directs Kabuto through Kimimaro's bone-disease operation, injecting prepared tissue fluid into his spine while Kabuto transplants modified cells. Medical chakra encourages the cells to take without ordinary stitches. 239
• Arranges Hidan's modified-cell transplant to increase regeneration without granting Wood Release, using Kakuzu's threads to close the wound. 257
• Begins an experimental Hōzuki-cell transplant intended to give Yahiko the clan's body-liquefying ability. 277
• Transplants Fugaku's eyes into Sasuke and supplies replacement eyes for Fugaku. He later confirms that the method used also preserves Great Tōnai Debate within Sasuke's transplanted eyes. 319 334

Kimimaro's successful treatment demonstrates the healing potential of Orochimaru's methods, but he notes that the high cost restricts the procedure to selected individuals. 239

Cell Engineering and Artificial Organisms

Hashirama cells form the foundation of much of Orochimaru's later research. His work distinguishes their vitality and rapid reproduction from the specific genetic and chakra properties that produce Hashirama's abilities. 173 183 184

• Analyzes White Zetsu's structure within one month and enables Obito to fully adapt to the Hashirama cells composing half his body. 173
• Develops downgraded cells that can be mass-produced, proposing artificial replicas with chakra closely resembling Madara, Black Zetsu, Hashirama, and tailed beasts. These replicas are not described as possessing all the originals' developed abilities. 183
• Produces modified Hashirama cells with suppressed Water and Earth chakra transformations, reducing their activity and preventing uncontrolled multiplication or the acquisition of Wood Release after injection. 184
• Engineers cells that use chakra to envelop genetic fragments and perform simple genetic fusion between animals. 211
• Strengthens the Akatsuki's core members to varying degrees through cell engineering. 239
• Enhances Hidan's regeneration, combining rapid healing with his existing immortality. 257 258

Artificial Tailed Beasts

Orochimaru develops miniature tailed beasts whose biology and bodily functions closely resemble the originals. Their chakra can substitute for the corresponding tailed beasts in the Ten-Tails revival process, allowing the real jinchūriki to survive. 255 256 301 317

• Produces two miniature tailed beasts after two months of experiments following Roshi's capture. 254 255
• Supplies a miniature Four-Tails for sealing into the Demonic Statue of the Outer Path. 256
• Divides the simultaneous One-Tail and Seven-Tails work with Kabuto after Gaara and Fū are brought to the laboratory. 285
• Requires both Kushina and Naruto to prepare a miniature Nine-Tails using the Yin and Yang halves. 293
• Obtains material for a miniature Eight-Tails through Killer B's examination and works overtime to finish the Eight-Tails and Nine-Tails replicas. 298 300
• Proposes giving miniature tailed beasts to promising Konoha youths to enhance their combat ability; Xuanhui approves. 273

He distinguishes these mindless artificial versions from the genuine tailed beasts, noting that Naruto's ability to connect with the originals cannot be replaced by manufactured power. 273

Reincarnation and Life Extension

Orochimaru studies both Living Corpse Reincarnation and Impure World Reincarnation, using White Zetsu as experimental resources and substitute bodies. 173 175

• Transfers into a White Zetsu whose body assumes his appearance, afterward declaring himself immortal. This demonstrates his life-extension method rather than establishing absolute invulnerability. 175
• Uses Impure World Reincarnation to revive Mito Uzumaki, who praises his skill and confirms that her strength is close to its level in life. 244
• His reanimation work brings Hashirama, Tobirama, and Mito back into contact with Hiruzen and the modern shinobi world. 318
• Extracts residual Black Zetsu chakra during Obito's Living Corpse Reincarnation procedure; Obito later gives the sample to Mito for her Six Paths-level sealing technique. 331

Ryūchi Cave and Sage Mode

Orochimaru maintains access to Ryūchi Cave and its White Snake Sage. He takes Xuanhui there to learn Sage Mode and subsequently seeks to study the effects of his disciple's senjutsu chakra. 106

He later persuades the White Snake Sage to accept Kabuto and Kimimaro without the usual trials. When offered the opportunity to learn Sage Mode himself, Orochimaru declines, stating that he has found his own path. His role in arranging and studying Sage Mode therefore does not establish that he personally masters it. 263

Espionage and Covert Communication

Orochimaru spends years embedded in the Akatsuki while maintaining Xuanhui as his secret contact. He disguises his participation through claims of defection and human-experimentation ambitions, while gathering research materials relevant to the larger plan against Madara, Kaguya, and the Ōtsutsuki. 164 168 201

• Accepts Obito's offer of White Zetsu while openly expressing scientific interest in modifying his eye. 168
• Maintains secret exchanges of research results and engineered cells with Xuanhui. 184 211
• Designs a simple sealing-imprisonment explanation for his eventual return, arguing that an overly detailed account would invite scrutiny from Konoha's intelligent investigators. 250
• Publicly presents his return as rescue from a seal in Kirigakure's ruins while Minato privately knows the undercover circumstances. 288
• Secretly delivers miniature Eight-Tails and Nine-Tails through a snake during Obito's apparent attack on the jinchūriki protection squad. 301

Relationships

• Xuanhui — Disciple, former jōnin subordinate, research companion, and the person most responsible for softening Orochimaru’s behavior. Orochimaru trains him, supports his missions, worries over his condition, and calls him more than merely a disciple. 3 4 5 30 42 He offers S-rank missions as practice and funding, recognizes Xuanhui's readiness to graduate, and accepts a wager that leads to their journey together. Xuanhui later becomes his secret contact during the Akatsuki infiltration, while their reunions retain affectionate teasing. 45 69 75 168 214 287
• Hiruzen Sarutobi — Teacher and Lord Third. Hiruzen initially leaves Xuanhui’s training to Orochimaru, while Orochimaru later teases him for effectively handing over such a gifted disciple. 3 5 Hiruzen refuses unrestricted forbidden-technique access, protects Nawaki during Orochimaru's research, and reluctantly accepts the account of Orochimaru's undercover departure. Their later reunion is warm, and Hiruzen offers to show him the changed village. 47 63 168 288
• Jiraiya — Longtime friend and battlefield comrade. Orochimaru persuades him to return to Konoha when war approaches; they later cooperate against Kakuzu and alongside Tsunade during the Hidden Rain conflict. 12 19 35 Orochimaru delivers Jiraiya's wedding gift to Tsunade and later serves with him in the jinchūriki protection squad. 108 297
• Tsunade — Fellow Sannin and research collaborator. They work together on poison-related research, though Tsunade’s superior medical chemistry knowledge exposes Orochimaru’s limitations in that field. 26 38 They also coordinate Xuanhui's eye surgery, and she warmly welcomes Orochimaru after his return from the Akatsuki. 67 288
• Manda — Summoned snake partner. Their relationship is tense, with Orochimaru relying on threats and compensation to compel Manda’s assistance. 19
• Yahiko, Konan, and Nagato — Hidden Rain war orphans. Orochimaru initially recommends killing them to spare them suffering but relents after Xuanhui’s intervention; Jiraiya remains behind to train them. 46 They later become his Akatsuki associates. He expresses interest in Nagato's Rinnegan, gives Konan special-paper instructions and Tobirama's Mutually Multiplying Explosive Tags technique, and begins Yahiko's Hōzuki-cell surgery. Yahiko and Konan do not hold his earlier threat against him. 166 277
• Senju Nawaki — Beneficiary of Orochimaru's Hashirama-cell research. Orochimaru celebrates his survival, promises him a prosthetic limb, and reassures him that he will not be taken away by Root. 63
• Danzō Shimura — Political antagonist who attempts to coerce Orochimaru into infant experimentation and whose operatives later try to enter his laboratory. Orochimaru rejects his demands, participates in the confrontation against him in Amegakure, and claims responsibility for his assassination in his farewell letter. 64 96 163 164 168
• Kakuzu — Initially an enemy encountered during the caravan escort, later a traveling companion, research supplier, and fellow Akatsuki infiltrator. Kakuzu provides Takigakure's techniques, helps recover the Kusanagi Sword, and cooperates with Orochimaru against Hanzo and Danzō. 19 20 86 89 164 167
• Obito Uchiha — Covert ally and research subject who publicly approaches Orochimaru as “Madara.” He supplies White Zetsu in exchange for work on his strained eye and damaged body, and funds research valuable to the Akatsuki's plans. Orochimaru improves his cellular compatibility and later extracts Black Zetsu chakra during his reincarnation procedure. 168 173 239 331
• Black Zetsu and White Zetsu — Sources of research material and participants in the deception surrounding the Akatsuki. Orochimaru uses White Zetsu as artificial experimental subjects and a replacement body, while presenting research and cover stories to Black Zetsu without revealing his actual loyalties. Black Zetsu later becomes suspicious of his role in disrupting the Eye of the Moon plan. 173 175 183 250 324
• Kabuto Yakushi — Apprentice and medical assistant. Orochimaru praises his precision, guides him through Kimimaro's operation, divides artificial-tailed-beast work with him, and obtains Sage Mode instruction for him. 239 263 285
• Kimimaro — Young assistant and patient whose hereditary bone disease Orochimaru successfully treats with Kabuto's help. Kimimaro responds with profound gratitude, and Orochimaru later arranges his Sage Mode training. 239 263
• Dan Katō — Friend initially met through their shared interest in Tobirama's techniques. Dan asks for help improving Spirit Transformation, and later joins Tsunade and Hiruzen in welcoming Orochimaru back to Konoha. 60 288
• Tobirama and Hashirama Senju — Revived predecessors and research collaborators. Orochimaru admires Tobirama's inventions and policies before eventually working with the brothers on the Ōtsutsuki threat and coordinating their return to the battlefield. 76 219 288 308
• Mito Uzumaki — Revived through Orochimaru's Impure World Reincarnation. She praises his capabilities, and material extracted through his work later assists her Six Paths-level sealing technique. 244 331
• White Snake Sage — Leader of Ryūchi Cave and the source of Sage Mode instruction for Xuanhui, Kabuto, and Kimimaro. Orochimaru negotiates access for his younger companions but declines training himself. 106 263
• Sasori — Orochimaru helps arrange his reconciliation with Chiyo and the Third Kazekage after his confrontation with Sakumo. Later, Sasori benefits from Orochimaru's chakra-battery technology. 109 110 111 285
• Sasuke and Fugaku Uchiha — Orochimaru assists Sasuke's wartime advancement by transplanting Fugaku's eyes into him and fitting Fugaku with replacements. He later explains the additional ocular ability preserved by the procedure. 317 319 334
• Gaara and Fū — Captured jinchūriki brought to his laboratory for miniature-tailed-beast research. Orochimaru later rescues them and brings them back with him when his undercover mission ends. 285 287

Story Role / Major Arcs

Xuanhui's Mentor

Orochimaru becomes Xuanhui’s teacher after their discussion at Ichiraku Ramen, then takes responsibility for his practical development as a ninja. He teaches chakra control, combat fundamentals, Lightning Release, awareness, and mission discipline. 3 4 11 15

As Xuanhui matures, Orochimaru encourages more intensive training, applies for his Chūnin examination, and supports his innovative bloodline-limit research. Their relationship develops into a partnership in which instruction and scientific discovery flow in both directions. 6 30 32

His declaration that Xuanhui is ready to graduate does not end their personal bond. Their nighttime conversation and wager establish a shared future as traveling companions, and Orochimaru continues to facilitate advanced training by taking Xuanhui to Ryūchi Cave. 69 106

Caravan Escort and Kakuzu Encounter

As Xuanhui’s squad leader, Orochimaru joins him and Jiraiya on a merchant escort mission. He fights Kakuzu with Wind Release, Manda, and Triple Rashomon while coordinating with Jiraiya’s summons. 14 19 20

Hidden Rain War

Orochimaru helps lead Konoha’s response to Hidden Rain, receives Xuanhui’s intelligence reports, assigns him dangerous reconnaissance, and conducts poison research after Hanzo’s forces become a major threat. He is severely injured in the ensuing battle but survives. 34 35 36 37 38 39 40 41 42

War Orphans and Return to Konoha

Orochimaru’s harsh proposal for the Hidden Rain orphans is challenged by Xuanhui, causing him to reconsider. Back in Konoha, he seeks access to forbidden techniques for research and improvement purposes. 46 47

Hashirama-Cell Research and Danzō's Pressure

Orochimaru's research becomes central to Nawaki's survival and prospective Wood Release ability. The successful case exposes a conflict between Hiruzen's protection of Nawaki as a person and Danzō's wish to control him as a strategic asset. 63

Danzō's later attempt to recruit Orochimaru into infant experimentation is firmly rejected. The episode establishes both Orochimaru's resistance to Root's interference and the importance of preserving his relationship with Xuanhui. 64

Journey Through the Shinobi World

After the war, Orochimaru and Xuanhui depart with Hiruzen's permission to investigate ruins, gather techniques, and learn about other villages' medical training. Their expedition begins with the Uzumaki homeland and expands into a lengthy journey with Kakuzu. 75 76 78 86

Orochimaru's acquisitions include the Kusanagi Sword and Takigakure's secret techniques. His research contributes to understanding Xuanhui's Light Release, while encounters such as the rescue of the Uzumaki couple and the stay in the Land of Birds reflect his increasing capacity for compassion and open-ended exploration. The pair return to Konoha after seven or eight months. 86 89 92 96

Third Shinobi World War

Orochimaru brings his laboratory work to the front and trusts Xuanhui's independent plans. He guards another front with Kakuzu when asked and later rejoins the Iwagakure campaign, where he and Jiraiya have repeated encounters with the enemy jinchūriki. 123 128 141 254

When Iwagakure signs a ceasefire under combined military and diplomatic pressure, Orochimaru informs Xuanhui that the war is nearly over. 151

Akatsuki Infiltration and Research

Following Hiruzen's announcement that he will retire, Orochimaru accepts Xuanhui's copied Forbidden Techniques Compendium and prepares to enter Amegakure. He attacks Danzō's forces with Many Snake Formation and uses the Eight Branches Technique during the confrontation with Hanzo. After the battle, he and Kakuzu join the Akatsuki. 161 163 164 166 167

His apparent departure masks an undercover assignment with Xuanhui as his contact. White Zetsu gives him a plentiful artificial resource for cell engineering and reincarnation research, while Obito's desire for physical improvement provides organizational backing. 168 173 175

Orochimaru becomes the Akatsuki's principal technical supporter rather than a regular mission operative. His work strengthens members, cures Kimimaro, improves Hidan's regeneration, and offers Yahiko and Konan new means of fighting. His costly experiments also absorb substantial organizational funding. 239 257 277

Artificial Tailed Beasts and Return to Konoha

Orochimaru's miniature-tailed-beast project supports a plan to recreate the necessary tailed-beast chakra without killing the real hosts. Roshi's capture supplies the first major experimental case, and later captures expand the work to other beasts. 250 254 255 256 285

After rescuing Gaara and Fū, Orochimaru reunites with Xuanhui and Pakura and returns to Konoha. Minato restores his registration while preserving the public sealing-imprisonment account, and Orochimaru reconnects with his former comrades. 287 288

Ōtsutsuki Research and Allied War Preparations

Orochimaru's research is informed by the future timeline Xuanhui has shown him, including Kaguya and Isshiki. He investigates White Zetsu as possible weapons against the Ōtsutsuki and collaborates with Hashirama and Tobirama on the larger threat. 201 216 219 288

He joins the jinchūriki protection squad and presents sample collection as an inter-village scientific exchange. After creating miniature Eight-Tails and Nine-Tails, he covertly delivers them through a snake into Kamui, allowing the Ten-Tails plan to proceed while the original hosts remain alive. 297 298 300 301 317

He also alerts the moon researchers to Madara's approaching revival and coordinates their return to gather the remaining Kage. 308

Battlefield Medical Support

Orochimaru, Tobirama, and Fugaku approach Sasuke with an offer to help him stand alongside Naruto. Orochimaru performs the eye transplant using Fugaku's eyes and gives Fugaku replacements before traveling toward the main battlefield with Kabuto, Kimimaro, and Yugito. 317 319

As the conflict escalates, Orochimaru and Kabuto move toward Obito after Kakashi pierces his heart. Orochimaru's extraction of residual Black Zetsu chakra during Obito's reincarnation procedure later contributes to Mito's sealing countermeasure. 322 331

Battle in Kaguya's Dimensions

Kaguya transports Orochimaru and five other fighters into her lava dimension. He remains close to Xuanhui, Kakashi, and Obito while Naruto and Sasuke conduct the principal attacks. 333

During the regrouping, Orochimaru confirms that Sasuke's transplanted eyes contain Great Tōnai Debate, helping clarify an available strategic tool. In the icy dimension, he supports the group's escape by using a snake to hold Xuanhui as they withdraw with Obito. He subsequently declines to watch Naruto's Reverse Harem Technique. 334 335
