Xuan Yu

Biodata

Physical Description

Xuan Yu initially appears outwardly ordinary, to the point that Kisame and other Akatsuki members judged him unimpressive by appearance alone 10. He is a male shinobi of average build whose appearance can be altered through Mystical Palm Technique-derived cellular control; while operating under the identity of Uchiha Genba, he changed his hairstyle, facial muscles, skin, and fat cells to reshape his face 60.

His most recognizable physical feature is his Sharingan. Xuan Yu awakened a Three Tomoe Sharingan through the Pay-to-Win System and received an optional Mangekyō Sharingan evolution 40. He later removed Kakashi Hatake's transplanted Mangekyō Sharingan, gouged out one of his own eyes, and implanted Kakashi's eye to access the Kamui Dimension 81. He subsequently acquired the Yellow Tenseigan from Hamura Shrine, although the accounts do not establish that he transplanted it into his own socket 218.

Xuan Yu normally favors practical combat clothing. He is known to wear Uchiha clan combat gear and has also appeared in Akatsuki's black robe with red clouds, though he rarely wears the latter 146. His extreme speed, Phantom Body Flicker, and later Speed Force manifestations make him appear as a blur, afterimage, or bolt of black lightning in combat 10 14 101.

• Hair color: Unknown; he can alter his hairstyle and appearance through cellular manipulation 60.
• Eye color: Natural eye color undocumented. He possesses a Three Tomoe Sharingan and Mangekyō Sharingan; he also seized the Yellow Tenseigan from Hamura Shrine 40 81 218.
• Typical attire: Uchiha clan combat gear; occasionally Akatsuki robes 146.
• Notable features: Mangekyō Sharingan and Kamui 40 81; Complete Body Susanoo 73; extreme speed and Phantom Body Flicker 14 101; cellular transformation capabilities 60 166; and chakra clones capable of assuming independent appearances, including Nohara Rin's likeness 102 125.

Personality

• Greedy and money-driven: Early in his career, Xuan Yu is primarily motivated by wealth, seeking to maximize profits through missions, negotiations, and side jobs. He negotiates payment with Orochimaru, initially asking for fifty million ryo before settling for ten million with the promise of more if he proves his worth 21. He also relentlessly grinds missions for commissions and bonuses, even planning a three-month non-stop mission route with Kakuzu 36. As his power and access to other worlds expanded, he increasingly treated money as fuel for his Pay-to-Win System; ordinary wealth in other worlds cannot necessarily be converted into system balance 223 230.

• Manipulative and cunning: Xuan Yu frequently uses deception and manipulation to get his way, often exploiting others for personal gain. He convinces Kakuzu to share a single inn room to save money despite Kakuzu's reluctance 20, pushes Kakuzu into continued mission grinding despite his fatigue 36, and uses specious reasoning to justify bounty theft at the Bounty Exchange 8. He also leverages Black Zetsu's desire to revive Kaguya into a five-hundred-million-ryo advance for Tailed Beast bounties 166.

• Resourceful and strategic: He makes efficient use of his abilities, deploying Chakra Clones to complete low-level missions while he handles higher-value work 16. He sends clones to meet dangerous contacts, including Orochimaru, to keep his main body secure 21, and maintains an intelligence network through Ninja Cats to locate high-bounty targets 19. In later cross-world operations, he establishes public and covert organizations, dispatches empowered clones to new worlds, and uses the World Tree to monitor connected realities 216 223.

• Overconfident and bold: Xuan Yu displays little fear when confronting powerful figures. He attacks Orochimaru without provocation to demonstrate his value to the Akatsuki 11, demands high compensation from Heavenly Path Pain 12, and taunts Kakuzu in battle 6. After his later growth, he openly considers himself invincible within the Ninja World and treats even Otsutsuki-derived threats as insufficient to stop him 101 217.

• Nonchalant and calm under pressure: He remains casual in dangerous situations, including during negotiations with Orochimaru and while handling rare system rewards 21 86. This composure continues in other worlds, where he can casually teleport allies across continents or dismiss powerful supernatural enemies as cannon fodder 212 225.

• Callous and self-centered: Xuan Yu frequently prioritizes his own goals over the welfare of others. He disregards complaints from mercenaries harmed by his bounty-stealing 8 and gouges out his own eye to implant Kakashi's Sharingan without hesitation 81. He later kills Saddler and Wesker without mercy and offers defeated supernatural beings the choice of becoming subordinates or slaves subject to brainwashing 212 244.

• Relentless and high-endurance: Xuan Yu possesses extraordinary stamina and drive, suggesting three months of uninterrupted mission grinding even as Kakuzu becomes exhausted 36. His pace eventually forces Kakuzu, a centuries-old ninja, to take leave for mental recovery 62.

• World-shaping pragmatist: Although he occasionally aids individuals and prevents tragedies, Xuan Yu's help is generally tied to long-term plans, amusement, or utility. In the Jackie Chan Adventures world, he ultimately eradicates both Black Qi and Positive Qi-aligned supernatural systems, arguing that neither force should dictate the fate of all beings 244.

Background and History

Xuan Yu was originally an ordinary civilian member of the Uchiha clan in Konohagakure. A war orphan whose parents died in conflict, he had reached the age of eighteen without awakening even one tomoe of the Sharingan and was regarded as a talentless good-for-nothing within the clan 20. His Uchiha background brought him little benefit and considerable trouble. He was driven from the Leaf Village and urgently sought strength through two means: acquiring ninjutsu and earning money to purchase upgrades through his unique Pay-to-Win System 3. Early on, he scoured black markets and posted bounty missions without success. Granny Cat, the weapon-shop owner in the Empty District, provided him meals and advice, though she doubted his ninja potential 3.

Xuan Yu's first major step toward power came when he intercepted Akatsuki member Kakuzu. After training and upgrading his taijutsu, Xuan Yu confronted Kakuzu, evaded his Earth Spear and Fire Style attacks, and sent the veteran ninja flying with Leaf Whirlwind 5 6. Rather than kill Kakuzu, he taunted him and encouraged him to accept more missions, intending to benefit from Kakuzu's activities. This encounter began a partnership that defined Xuan Yu's early career as a mercenary. Kakuzu later invited him into the Akatsuki, but Xuan Yu declined full membership in favor of working as a paid mercenary 11.

Xuan Yu's proposal to Akatsuki leadership—Heavenly Path Pain and Konan—was characteristically audacious. He demonstrated his value by attacking Orochimaru to display his speed and combat ability, using a Phantom Body Flicker comparable to Uchiha Shisui's signature technique 11 14. Pain and Konan were disturbed by his rapid growth and knowledge of Akatsuki secrets, including Heavenly Path's nature and the plan for Tailed Beast Weapons 12. They chose to recruit rather than eliminate him. His cooperation with Kakuzu became formal: Kakuzu handled high-value targets while Xuan Yu used Chakra Clones and Ninja Cat intelligence to grind lower-ranked missions 16 30. Their earnings for Akatsuki were exceptionally high, while Xuan Yu became notorious in black markets as a “commission harvester” who robbed mercenaries, stole bounties, and double-crossed targets 62. Kakuzu eventually took leave, mentally exhausted by Xuan Yu's work pace 62.

Xuan Yu also developed a complex relationship with Orochimaru. After initially attacking him to impress Akatsuki, Xuan Yu approached Orochimaru to learn ninjutsu from his scrolls. He rapidly mastered Healing Jutsu and upgraded it through the system, astonishing the Sannin 23. During a spar, he demonstrated his Chakra Clone ability and offered Orochimaru valuable chakra for research in exchange for payment and cooperation 24 25. Orochimaru agreed while secretly considering Xuan Yu as a potential reincarnation vessel 24 26. Their arrangement later reversed the balance of power when Xuan Yu saved Orochimaru from Uchiha Itachi, used Gubraithian Fire to restrain Amaterasu, and compelled Orochimaru to research two techniques in exchange for the rescue 129 130.

Xuan Yu's involvement in the Uchiha Clan Downfall was pivotal. He negotiated a deal with the Lord Third, Sarutobi Hiruzen, for one hundred million ryo and Kakashi's Sharingan, then intervened during the massacre 73. Confronting Itachi, he used multiple Phantom Body Flickers and a Complete Body Susanoo to halt the killing spree, shocking Fugaku, Mikoto, and the surviving Uchiha 73. He later rescued Izumi from Tsukuyomi, accepted her as his first disciple, and established the Yu Sect within the Kamui Dimension 76 116.

As his speed and spiritual attributes increased, Xuan Yu's ambitions expanded beyond the Ninja World. At 60,000 speed, he fully activated the Speed Force and surpassed Mach 80; his increased spirit substantially amplified his chakra, Kamui, and Crazy Diamond 101. He began treating basic attributes as subject to diminishing returns and focused increasingly on special effects, talents, cross-world abilities, and dimensional travel 101. The God Tree seedling in his Kamui Dimension developed into a World Tree capable of linking other worlds, exposing fragments of countless realities to him 117 166.

Xuan Yu acquired Firebending, Gubraithian Fire, Wood Release, Mysterious Peacock Method, the Reverse Eight Gates, and increasingly potent Mystical Palm Technique effects over the following period 118 152 157 166. He also captured multiple Tailed Beasts, including the Four-Tails, Eight-Tails, and Seven-Tails, while obtaining Hero's Water and the Yellow Tenseigan 166 217 218. His negotiations with Black Zetsu centered on Tailed Beast bounties and Kaguya's eventual resurrection 166.

After the World Tree opened stable cross-dimensional routes, Xuan Yu sent clones to other worlds. His forces entered the Resident Evil world, where the U Organization operated as a base for Leon, Eida, Apocalypse, and other agents 212. The gains from that world provided one hundred and eighty billion usable system balance, allowing Xuan Yu to raise all four core attributes to 250,000 points each 243.

Xuan Yu also dispatched Number Six, initially carrying two percent of his power, to the Jackie Chan Adventures world 216. There, the clone worked alongside Jackie Chan's group, recovered Talismans and Shadowkhan masks, formed a temporary alliance with Shendu, defeated supernatural enemies including Zhong Su and Xiao Fung, and brought Tara, Daolon Wong, Xiao Fung, Shendu, and the Shadowkhan into the Kamui Dimension 238 243 244. Number Six then used mass shadow clones, Infinite Tsukuyomi, and seven days of world-scale reconstruction to remove supernatural forces and sever the world's predetermined balance of Positive Qi and Black Qi 244.

Following Number Six's return, Xuan Yu gathered the Xuan Yu Dimension and World Tree into a single point, slowed time in the Ninja World to an extreme degree, and departed to personally travel through endless time and space 244.

Power Progression

Abilities and Skills

Taijutsu

Xuan Yu's taijutsu foundation centers on the Leaf Whirlwind, a Konoha-style high kick mastered to an extraordinary degree. After upgrading the technique to Level 10, it gained the special effect “Whirlwind Fierce Kick,” allowing him to generate a powerful whirlwind with each kick, capable of sending elite shinobi such as Kakuzu flying 22. He repeatedly uses this move as a close-quarters offense and can accelerate his kicks beyond Orochimaru's perception 6 24.

Beyond Leaf Whirlwind, Xuan Yu possesses Gale Instant Strike, which functions as a short-range teleportation technique. After striking an object, such as a kicked rock, he can instantly flash to its location, effectively creating a youth-version Flying Thunder God mobility option that can be chained in mid-air 59. He also possesses a rare Cosmic Phantom Beast Fist skill fragment obtained through recreating Ultraman Seven's jeep-training scene 88.

Xuan Yu later mastered the Eight Inner Gates and upgraded it to Level 10. Unlike the normal Gates, his Reverse Eight Gates promotes recovery and cellular activity, allowing him to benefit from the technique without the normal destructive consequences 152.

• Leaf Whirlwind Lv10 – A spinning kick that unleashes a whirlwind capable of blasting away durable opponents such as Kakuzu 22 6.
• Gale Instant Strike – Instantly teleports Xuan Yu to the location of an object he has struck, enabling rapid repositioning and aerial chains 59.
• Eight Inner Gates Lv10 – A mastered forbidden taijutsu capable of opening all eight gates and dramatically amplifying speed and strength 152.
• Reverse Eight Gates – A special Level 10 variant that enhances recovery and cellular activity rather than destroying the user's body 152.
• Cosmic Phantom Beast Fist (Pseudo-Weakened/Simplified Version) – An extremely rare skill fragment whose complete potential remains unrealized 88.

Ninjutsu

Xuan Yu's ninjutsu repertoire is broad, built on the Three Body Technique and Body Flicker Technique. Both were upgraded to Level 10 with powerful special effects. The Three Body Technique gained the “Chakra Clone” effect, allowing him to create lifelike clones made of chakra that are nearly indistinguishable from the real body and can operate almost as real bodies 22 24. The Body Flicker Technique gained “Phantom Body Flicker,” enabling multiple illusory bodies that Xuan Yu can switch between freely; the phantoms are immune to attacks and can strike simultaneously 13 22.

He later enhanced Body Flicker with Vision Teleportation, allowing blink-like movement to locations within his line of sight 102. His speed and clone capabilities were eventually augmented by an upgraded Multiple Shadow Clone Technique above Level 20, allowing Number Six to create countless forms for global operations 244.

Xuan Yu rapidly learned Healing Jutsu from Orochimaru's scroll and upgraded it to Level 10, gaining a special effect capable of rapidly restoring severe injuries 23 40. At Level 40, Mystical Palm Technique evolved into a powerful self-modification and regenerative system, granting Super Speed Regeneration and Advanced Cell Division Control in addition to defensive effects 166.

His catalog also includes more than one hundred low-rank techniques acquired through Kakashi, including Lightning Release: Lightning Blade, alongside standard elemental techniques such as Fire Style: Great Fireball Technique 101. Scratch-card rewards later gave him Wood Release, Firebending, Gubraithian Fire, and the Mysterious Peacock Method 118 157. His immense chakra reserves make even conventional Water Style overwhelmingly potent, as shown when he forced back Water Demon Bai Tza's attacks 240.

• Chakra Clone – A Three Body Technique effect creating nearly perfect chakra clones that can monitor Xuan Yu and operate independently 20 22 24.
• Multiple Shadow Clone Technique – An advanced clone technique raised above Level 20, allowing massive simultaneous deployment 244.
• Phantom Body Flicker – Creates multiple intangible phantoms between which Xuan Yu can freely switch 13 22 24.
• Vision Teleportation – A line-of-sight, blink-like form of teleportation developed from Body Flicker 102.
• Healing Jutsu Lv10 – Medical ninjutsu with a special effect capable of rapidly treating severe wounds 23 40.
• Mystical Palm Technique Lv40 – Medical and cellular-control ninjutsu granting Super Speed Regeneration, Advanced Cell Division Control, Symbiotic Transformation, and Immunity to All Techniques 166.
• Fire Style: Great Fireball Technique – A standard Uchiha fire technique acquired from a scratch card 40.
• Lightning Release: Lightning Blade – One of many techniques obtained through Kakashi's extensive ninjutsu collection 101.
• Wood Release – A bloodline-level ability obtained through a scratch-card reward; Xuan Yu used Wood Pillar House Technique to create extensive wooden structures 118.
• Firebending – A talent granting fine control over flame, including the ability to seize and reshape the power of the Dragon Talisman and Fire Demon Chi 118 237.
• Gubraithian Fire – An eternal magical flame that can contend with Amaterasu and was used to rescue Orochimaru from Itachi 119 129 130.
• Mysterious Peacock Method Lv20 – Generates chakra wings for high-speed flight and grants Adaptive Circuit and Sky Dominator 139 157.
• Infinite Tsukuyomi – Used by Number Six while purging supernatural forces from the Jackie Chan Adventures world 244.

Dojutsu

Xuan Yu awakened a Three Tomoe Sharingan through the Pay-to-Win System and received the ability to choose a Mangekyō ability 40. He selected Kamui, a space-time dōjutsu allowing dimensional transport, intangibility, and the ability to send people or objects into a separate dimension 64 81. He physically transplanted Kakashi's Mangekyō Sharingan to access Obito's Kamui Dimension and used Crazy Diamond's Repair to manage the transplantation process 81.

Kamui ultimately became central to Xuan Yu's cross-world power structure. He used it to create passages into the Xuan Yu Dimension and to transport Tara, Shendu, Daolon Wong, Xiao Fung, and the Shadowkhan out of their original world 244. His Sharingan also strengthens Phantom Body Flicker, whose effectiveness is linked to ocular power 22.

Xuan Yu has also demonstrated Complete Body Susanoo, which he used to interrupt the Uchiha massacre 73. He later obtained the Yellow Tenseigan from Hamura Shrine, an ocular treasure previously kept near the moon 218.

• Three Tomoe Sharingan – Grants enhanced perception, copying ability, and genjutsu casting 40.
• Mangekyō Sharingan (Kamui) – Grants dimensional transport, intangibility, and spatial manipulation 64 81.
• Complete Body Susanoo – A complete armored chakra avatar displayed during the Uchiha Clan Downfall 73.
• Yellow Tenseigan – A powerful Tenseigan seized from Hamura Shrine; the accounts do not confirm its transplantation or full use by Xuan Yu 218.

Stand

Through a Stand Selection Opportunity obtained from a Growth Gift Pack, Xuan Yu acquired Crazy Diamond, an A-Rank Stand with both Power and Speed rated A. Crazy Diamond is invisible to anyone who is not a Stand user—effectively everyone in the Ninja World—and its strength scales with Xuan Yu's own attributes 58 64. Its primary ability is Repair, which restores objects, heals injuries, and can disassemble or reattach body parts. Xuan Yu has used it to repair Kakashi's eye socket and hot-swap Sharingan eyes during combat 81 88.

The Stand's physical punches are strong enough to shatter cliffs and level a hundred-meter radius after Xuan Yu's strength breakthrough 58 63. Since normal shinobi cannot perceive it, Crazy Diamond functions as a nearly undetectable trump card, comparable in practical stealth to a personal Limbo: Border Jail 58.

• Crazy Diamond – An A-Rank Stand with Power and Speed both rated A; its destructive force scales with Xuan Yu's own strength 58 64.
• Repair – Restores objects and living tissue to a prior state, healing wounds and reattaching severed parts 81 88.
• Physical Strikes – Invisible punches capable of demolishing rock and causing large-scale local destruction 58 63.

Other

Xuan Yu possesses numerous powers outside conventional ninja classifications. The Speed Force is tied to his base speed attribute. At 10,102 speed, he unlocked the talent 27. At 40,000 speed, he could vibrate his hand at extremely high frequencies to strengthen attacks and projected that 60,000 would allow true intangibility and 100,000 might permit time travel 81. At 60,000 speed, he fully activated the Speed Force and surpassed Mach 80, while later accounts describe his Speed Force-assisted peak speed as reaching two-thirds of the first cosmic velocity 100 101.

His rising spirit also produced psychic effects. By the time his spirit reached the 50,000-point threshold, he could sense danger in a Spider-Sense-like manner and move objects with telekinesis 139. Later, his psychic perception could scan approximately one kilometer precisely, or more than five kilometers at reduced precision, and could form chains extending from Earth to the moon 215 243.

The God Tree Seedling in the Kamui Dimension evolved into a World Tree, linking Xuan Yu's dimension to other worlds and enabling clone deployment, interdimensional observation, and eventual personal travel through the myriad realms 117 166 244. After gaining one hundred and eighty billion usable balance from the Resident Evil world, Xuan Yu raised each core attribute to 250,000, reaching a total of one million 243.

• Speed Force – Grants superhuman movement, high-frequency vibrational attacks, potential intangibility, and eventual time-space traversal 27 81 101.
• Psychic Perception and Telekinesis – High-spirit abilities allowing danger sensing, object manipulation, large-area scanning, flight support, and psychic restraints 139 215 243.
• Reverse Eight Gates – A recovery-oriented Eight Gates variant that improves cellular activity and suppresses harmful side effects 152.
• Mysterious Extraterrestrial Radiation Energy – A renewable resource obtained by topping up the Hoshigakure star; halves ability-upgrade costs 157.
• Adaptive Circuit – A passive Mysterious Peacock Method effect that further reduces upgrade costs and nullifies the method's normal side effects 157.
• Sky Dominator – Doubles Xuan Yu's movement speed while airborne, with no upper limit as his base speed increases 157.
• World Tree – The evolved God Tree sapling in the Xuan Yu Dimension, capable of connecting and observing other worlds 117 166.
• Hero's Water – A Takigakure treasure that provides a modest multiplication of chakra 217.
• Water Demon Qi – Power obtained after defeating and subduing Bai Tza 240.
• Rooster Talisman and Razo Mask – Cross-world artifacts acquired during operations in the Jackie Chan Adventures world 223 234.

Relationships

• Kakuzu: Xuan Yu’s initial Akatsuki partner. Their relationship is defined by profitable cooperation, constant bickering, and underlying hostility. Kakuzu repeatedly finds that he cannot easily kill Xuan Yu despite his reputation as a teammate-killer 12 30. Xuan Yu steals bounty targets, freeloads on Kakuzu's provisions, and pushes him into punishing mission schedules 18 26 30 37. Kakuzu ultimately takes leave because of the mental exhaustion caused by trying to keep pace with him 62.

• Orochimaru: A fraught alliance built on mutual utility and coercion. Orochimaru initially views Xuan Yu as a promising research subject and potential reincarnation vessel 14 15 30. After Xuan Yu saves him from Itachi, Orochimaru is forced to research two techniques in return and continues cooperating on Xuan Yu's terms 129 130.

• Uchiha Itachi: A tense dominant-subordinate relationship. Xuan Yu halts Itachi’s massacre of the Uchiha clan with Phantom Body Flickers and Complete Body Susanoo 73 74. After Itachi attacks Izumi, Xuan Yu forces him into Akatsuki as a “little sidekick” 114. They later clash over Orochimaru, but Xuan Yu allows Itachi to maintain his mole activities conditionally 130 163.

• Uchiha Izumi: Xuan Yu’s first disciple and the first disciple of the Yu Sect. He rescues her from Tsukuyomi and trains her within the Kamui Dimension 76 116. Izumi admires him deeply, particularly after his displays of Wood Release, Firebending, and Gubraithian Fire, while Xuan Yu publicly insists that their relationship is a formal and “pure” master-disciple bond 114 118.

• Terumi Mei (Fifth Mizukage): A flirtatious and potentially romantic connection. Xuan Yu takes her to Ichiraku Ramen during diplomatic dealings and openly admires her appearance, while their banter suggests mutual interest 123 125.

• Konan: A professional, no-nonsense associate. Konan arranges Xuan Yu’s accommodation in Amegakure, attempts to mediate internal Akatsuki conflicts, and is repeatedly surprised by his audacity and rate of growth 12 14 129.

• Heavenly Path Pain (Nagato): Initially Xuan Yu’s employer under a paid mercenary arrangement. Xuan Yu demands thirty million ryo per year plus benefits, while Pain remains wary of a power he cannot reliably control 12 30. Xuan Yu later considers treating Nagato’s paralysis with Mystical Palm Technique, though he forgets to offer it at the time 130.

• Zetsu / Black Zetsu: Zetsu initially approaches Xuan Yu concerning Infinite Tsukuyomi, the Otsutsuki, and hidden Ninja World history, eventually suspecting that Xuan Yu is an Otsutsuki 130 131. Black Zetsu later negotiates Tailed Beast bounties with him and pays a five-hundred-million-ryo advance because of his devotion to reviving Kaguya 166.

• Kakashi Hatake: A tense and exploitative associate. Xuan Yu takes Kakashi’s Sharingan as payment, repeatedly removes and restores it, and ultimately implants it into his own eye to access the Kamui Dimension 73 81. Number One later replaces Kakashi’s eye and offers to resurrect Rin in exchange for obedience 125. Despite Xuan Yu’s abusive training methods, Kakashi benefits from some of his interventions 88 89.

• Sarutobi Hiruzen: A businesslike negotiating partner. Xuan Yu secures one hundred million ryo and Kakashi’s Sharingan from the Lord Third during the Uchiha crisis 73. Hiruzen recognizes that Xuan Yu is powerful, eccentric, and highly unpredictable 70.

• Uchiha Fugaku: A transactional ally. Xuan Yu, while masquerading as Uchiha Madara, offers to help the Uchiha escape Konoha through various paid “packages,” and Fugaku regards him as a possible savior 74 76.

• Shimura Danzō: Hostile. Danzō regards Xuan Yu as a dangerous obstacle during the Uchiha crisis, mistakes him for Uchiha Madara, and becomes increasingly paranoid about him 61 74.

• Root Organization: Xuan Yu demonstrates that he can suppress Danzō’s curse-mark control through a tuned Four-Symbols Seal, but dismisses Root personnel as too foolish to be worth recruiting 116.

• Number One (Shadow Clone): A difficult master-clone relationship. Number One acts independently, teases others, manipulates Kakashi, and behaves with enough arrogance that Xuan Yu becomes concerned about separating his own responsibility from the clone’s actions 124 125.

• Number Six: A cross-world clone initially supplied with two percent of Xuan Yu’s power and sent to the Jackie Chan Adventures world 216. Number Six becomes a major agent of Xuan Yu’s will, defeats supernatural enemies, purges the world’s magical balance, and eventually reunites with the main body 243 244.

• Leon and Eida: Agents of Xuan Yu’s U Organization in the Resident Evil world. They retrieve Amber and ancient parasites, receive Xuan Yu’s praise and transport back to the organization’s base, and serve as trusted operatives in his cross-world projects 212.

• Jackie Chan, Jade, and Uncle: Associates in the Jackie Chan Adventures world. Xuan Yu acts as their wealthy employer and benefactor, provides Jackie with a strengthening talisman, gives Jade a magical vehicle, rejuvenates Uncle, and relies on them to address threats that he considers beneath his direct attention 223 224 228.

• Shendu: A temporary ally in the Jackie Chan Adventures world. Although Xuan Yu initially opposes Shendu’s forces, the two cooperate to overturn the world’s Positive Qi and Black Qi balance 238. Shendu eventually enters the Kamui Dimension with Xuan Yu’s other captured supernatural allies 244.

• Tara, Daolon Wong, and Xiao Fung: Defeated supernatural adversaries who choose to leave their world with Xuan Yu rather than lose all prospects of power. Xuan Yu offers them the status of subordinates or slaves, with brainwashing as the alternative 243 244.
