Power Progression

Stage / Realm / Level	Chapter	Notes
Chakra extraction and exceptional control	1	Extracted chakra at age three and developed unusually precise control at a very young age.
Anomalous ocular awakening	8	His unknown eyes awaken at age five; he claims they allow him to perceive the future and uses that knowledge to warn Minato of the Nine-Tails’ Attack.
Chakra research combat techniques	4	After three years of experimentation, develops a powerful Fire Release attack and uses Reverse Summoning to move a stolen Nine-Tails chakra-sealing apparatus to Cat Ninja Village.
Overwhelming ocular chakra state	7	Resists Shisui’s right-eye Kotoamatsukami completely and repels him with an invisible force; his chakra is described as an immense aggregate of ocular power.
Byakugan chakra reserve revealed	9	Reveals that 100,000 cloned Byakugan are sealed within his body, providing tailed-beast-scale chakra that destroys Danzō’s curse mark.
Stabilized Three-Tomoe Sharingan	26	Uses an Eight Trigrams Seal to suppress and gradually release the sealed Byakugan power, restoring his original Three-Tomoe Sharingan while leaving faint blue traces in his pupils.
Byakugan-based x-ray vision	27 33	Gains color-based vision through solid matter, but prolonged use severely exhausts his eyes and strains his Sharingan.
Immature Tenseigan	31	Black Zetsu identifies Yansheng’s ocular power as an immature Tenseigan after his clone resists Kotoamatsukami.
Perfect Susanoo	43	Repairs and re-manifests a Perfect Susanoo using ocular power released from within his body.
Artificial Mangekyō Sharingan cultivation	46	The Little Ten-Tails’ evolutionary chakra enables him to produce Mangekyō Sharingan based on Kakashi’s Kamui and Shisui’s Kotoamatsukami.
Partial Tenseigan evolution	47	Uses a clone body and the ocular power sealed by the Eight Trigrams Seal to begin evolving Byakugan toward the Tenseigan; gains puppet-control capabilities.
Synthesized Tenseigan	48	Cultivates a Tenseigan in Hyūga-based clone bodies. It can create Truth-Seeking Orbs and absorb chakra at range, but has limited endurance and cannot replenish itself independently.

Background / History

Yansheng was orphaned as an infant and received limited material support from the Uchiha Clan. His talent earned him better treatment than most children, including food, instruction, and the care of his cousin Uchiha Inabi, but he largely developed through independent study and planning. He had extracted chakra by age three and understood that raw talent alone could not protect him from future Mangekyō Sharingan users or Konoha’s hostility toward the Uchiha. 1 2

At age five, Yansheng concluded that Minato Namikaze’s appointment as Hokage began the countdown to the Nine-Tails’ Attack and the Uchiha Clan Massacre. He created a disguised Shadow Clone, removed all detectable scent from an envelope, and delivered Minato intelligence concerning Obito, Kushina’s childbirth, and the planned attack. The clone’s delayed return caused Yansheng severe anxiety and mental pain, but its memories confirmed that Minato had received the warning. 1 2

Yansheng chose medical ninjutsu and chakra science over conventional Uchiha combat training. With Inabi’s support and Fugaku’s approval, he studied Konoha’s medical records, established a summoning contract with the Ninja Cat Clan, and built a laboratory near Cat Ninja Village. During the Nine-Tails’ Attack, he ignored Inabi’s evacuation order, ambushed chakra thieves, and seized a sealing device containing scattered Nine-Tails chakra for research. 3 4

By age ten, his experiments and unusual ocular power made both Konoha and the Uchiha suspicious of him. After defeating Shisui’s attempt to use Kotoamatsukami, Yansheng openly disclosed his future knowledge to Shisui and Fugaku. He forced the issue of Danzō’s stolen Sharingan, assaulted Danzō in the Hokage’s office, and leveraged his power into political concessions for the Uchiha Clan. Fugaku subsequently named him an elder and intended successor. 7 11

Appearance

Yansheng’s appearance is closely tied to the unstable evolution of his eyes. His ordinary Uchiha eyes can return to a Three-Tomoe Sharingan state, but his higher ocular states have produced increasingly abnormal coloration and patterns. 6 26 50

• His early anomalous state has white pupils, crimson irises, and pale-blue halos. 6
• When releasing immense ocular power, he can be enveloped in a deep-blue chakra cloak. 18
• After his Tenseigan-related evolution, his eyes appear pale blue, causing gate guards to question whether he is truly an Uchiha. 50
• He was ten during his confrontation with Shisui and Fugaku, and thirteen when he returned to Konoha after two years away. 7 50

Personality

Yansheng is cautious, analytical, and intensely survival-driven. His early actions are built around secrecy: he uses clones, masks, scent removal, false routines, transformations, and contingency plans rather than trusting superior opponents or political institutions. Even after gaining power, he remains suspicious of traps and prefers to force enemies to approach ground he has prepared. 1 24 29 48

He is bluntly contemptuous of leaders he considers weak or hypocritical, particularly Fugaku, Hiruzen, Danzō, and Shisui. He repeatedly uses future knowledge to pressure others into action, but does not regard prophecy as infallible after his interventions alter the timeline. 8 11 23

His research is pragmatic to the point of moral detachment. He considers cloning to be the creation of new life, uses condemned criminals and captured enemies as subjects, and treats bloodlines, bodies, souls, and ocular powers as materials for experimentation. Nevertheless, he states that his goal is to ensure that neither he nor those he cares about can be harmed. 15 30

Abilities & Skills

Foreknowledge

Yansheng claims that his anomalous eyes allow him to see the future, using this knowledge to identify Obito, predict the Nine-Tails’ Attack, and expose the projected destruction of the Uchiha Clan. 8 9

• Uses future knowledge as political leverage against Fugaku, Shisui, Hiruzen, and Danzō. 8 10
• Recognizes that saving Kushina and Minato has changed the timeline enough to make later events unpredictable. 23
• Mixes truth with misinformation when discussing Black Zetsu in order to hide the extent of his knowledge. 34

Ocular Power

Yansheng’s original Sharingan became entangled with the chakra of 100,000 sealed cloned Byakugan, creating an unstable ocular state that initially resembles neither a normal Sharingan nor a true Tenseigan. 9 26

• Resists Shisui’s Kotoamatsukami, with the technique dissipating into his immense ocular chakra. 7
• Produces invisible repulsive force capable of blasting Shisui through a wall. 7
• Forms skeletal and later complete Susanoo-like chakra constructs. 8 43
• Uses Byakugan-derived x-ray vision to inspect bodies, seals, and hidden material. 27 33
• Suffers severe visual exhaustion after extended x-ray vision, and the Byakugan power strains his Sharingan. 33

Tenseigan

Yansheng develops a Tenseigan through Hyūga-derived clone bodies cultivated by the Little Ten-Tails. Its power is stated to approach the Rinnegan’s level, though it remains dependent on external chakra sources. 47 48

• Creates Truth-Seeking Orbs. 48
• Absorbs chakra from a distance. 48
• Uses puppet-control power to animate and manipulate clone bodies. 47
• Has chakra capacity comparable to half of the Eight-Tails. 48
• Cannot replenish itself naturally; when depleted, it must draw from his sealed Byakugan chakra or another external source. 48

Ninjutsu and Forbidden Techniques

Yansheng rapidly learns and adapts techniques across multiple disciplines, favoring methods that improve mobility, survival, sealing, or experimentation. 3 34 43

• Shadow Clone Technique — Modifies clones for espionage, long-term transformation, combat, and remote experimentation; recalled memories can inflict severe mental strain on his original body. 1 2 21
• Transformation and Body Flicker Techniques — Uses transformation for disguises, infiltration, and obtaining research funds; uses Body Flicker for rapid movement. 1 3 4
• Izanagi — Learns the Uchiha forbidden technique and uses a Three-Tomoe Sharingan embedded in replicated Hashirama Cells to overwrite a fatal outcome during Black Zetsu’s attack. 21 32 33
• Flying Thunder God Technique — Memorizes the technique from the Book of Seals and masters fixed-point teleportation, though he cannot use its combat-oriented second stage. 34 43
• Spirit Transformation Technique — Transfers his consciousness into prepared clone bodies without immediately abandoning his original body; incompatible bodies eventually reject his soul when their chakra is depleted. 46 48
• Impure World Reincarnation — Learns and tests the technique while researching the relationship between bodies, clones, and souls. 34

Sealing Expertise

Yansheng begins with basic seals, then studies under Kushina Uzumaki and gains access to advanced Uzumaki methods. 4 26

• Masters the Four Symbols Seal and applies an Eight Trigrams Seal to regulate the Byakugan chakra stored inside his body. 26
• Uses seals to restrain White Zetsu specimens and protect research assets. 22
• Builds barriers, Flying Thunder God marks, traps, and layered defenses around the Little Ten-Tails and his laboratory. 48

Chakra Research and Artificial Life

Yansheng treats chakra as a biological and evolutionary subject. His work includes ocular cloning, Hashirama Cell research, emotional drugs, cellular viruses, artificial humans, and soul-related experimentation. 15 30 34 36

• Creates artificial human units, including Zero-One, Zero-Two, Zero-Three, and the Nohara Rin Unit. 16 31
• Uses the Nohara Rin Unit, equipped with a Three-Tomoe Sharingan, as a psychological weapon intended to target Obito. 16
• Develops Exploding Flies and other living chakra weapons; one such creation destroys Pain’s Planetary Devastation. 20
• Clones Byakugan and Sharingan, though early cloned Sharingan only reach the One-Tomoe stage. 35
• Conducts emotional experiments using drugs and genjutsu to measure links between emotion, hormones, thought, chakra, and the soul. 30

Little Ten-Tails

The Little Ten-Tails is a mutated Divine Tree fragment that Yansheng names and cultivates after it begins absorbing chakra and natural energy. It returns an evolutionary chakra that can alter nearby material. 46

• Produces the evolutionary feedback that enables Yansheng to cultivate artificial Mangekyō Sharingan. 46
• Obeys Yansheng’s direct commands despite an instinctive hunger for the Dragon Vein’s energy. 47
• Cultivates Tenseigan-bearing clone bodies using natural energy and Byakugan chakra. 48
• Remains a controlled but heavily secured asset; Yansheng surrounds it with barriers, marks, explosives, puppets, and contingency measures. 48

Equipment / Weapons / Items

• Sealed Byakugan reserve — 100,000 cloned Byakugan sealed within his body, used as a massive source of ocular power and chakra. 9 26
• Exploding Flies — Living chakra bombs used for ambushes and large-scale destruction. 20 24
• “Buu” / “Patrick Star” — A massive Exploding Fly used to destroy Planetary Devastation. 20
• Artificial human units — Combat and surveillance creations, including the Zero series and Nohara Rin Unit. 16 31
• Flying Thunder God kunai and marks — Used for fixed-point emergency teleportation and securing the Dragon Vein site. 43 47
• Little Ten-Tails fragment — A sealed sample retained as a precaution against the main organism. 48

Relationships

• Uchiha Inabi — Cousin, caretaker, and early mentor. He initially opposes Yansheng’s interest in medical ninjutsu but later supports his training and Ninja Cat summoning contract. 2 3
• Uchiha Fugaku — Clan head who becomes Yansheng’s political counterpart. After Yansheng forces concessions from Konoha, Fugaku names him an elder and intended successor. 8 11
• Uchiha Shisui — Distrustful clansman and frequent ideological opponent. Yansheng resists his Kotoamatsukami, warns him of his projected fate, and later helps free him from Black Zetsu’s control. 7 8 32 33
• Hiruzen Sarutobi — Political adversary and reluctant collaborator. Yansheng repeatedly forces Hiruzen into compromises, access to forbidden techniques, and support for Uchiha interests. 10 11 22 34
• Kushina Uzumaki — Sealing teacher and trusted ally. She allows Yansheng into her sealing space, trains him in Uzumaki techniques, and fights beside him against Black Zetsu. 26 31 32
• Kakashi Hatake — Uneasy mission partner. Yansheng uses clones to conceal his real involvement, mocks Kakashi’s limitations, and secretly places a failsafe in Kakashi’s Sharingan. 16 20
• Uchiha Itachi — Research subject and ideological opponent. Yansheng exposes him to projected future events, contributes to his artificial Mangekyō awakening, and later releases him from a two-year Izanami. 21 36 50
• Obito Uchiha — Major adversary. Yansheng reveals Obito’s identity, challenges his Eye of the Moon Plan, and repeatedly attacks him through clones and prepared traps. 9 23 24
• Ninja Cat Clan — Summoning allies who become closely aligned with Yansheng and guard his laboratories and research materials. 3 6 7
• Little Ten-Tails — Controlled experimental organism and cultivation tool. Yansheng treats it as a dangerous subordinate rather than a companion. 46 48

Story Role / Major Arcs

Minato Warning and Nine-Tails’ Attack

Yansheng begins the story by trying to prevent the coming disaster through information rather than force. His warning does not stop the Nine-Tails’ Attack, but Minato and Kushina survive, immediately altering the expected future. Yansheng exploits the attack to seize rare Nine-Tails chakra for his research. 1 4 23

Uchiha–Konoha Political Crisis

After revealing his future knowledge and power to Fugaku and Shisui, Yansheng openly confronts Danzō and Hiruzen over stolen Sharingan and Root experimentation. He secures concessions for the Uchiha, becomes an elder, and forms the Purge Squad to protect the clan’s interests and target Sharingan exploiters. 8 11

Shisui, Obito, and Black Zetsu

Yansheng treats Shisui’s capture as both a rescue crisis and a source of intelligence. His battles with Obito and Black Zetsu rely on Shadow Clones, artificial humans, sealing, and explosive traps. Though Shisui is eventually recovered, Black Zetsu escapes with intelligence on Yansheng’s abilities. 15 24 31 33

Cloud Delegation and Konoha’s Mobilization

Yansheng intercepts the Cloud Village’s attempt to abduct Hinata, uses the event to obtain Hyūga cells, and threatens Cloud with war. His actions shift practical authority away from Hiruzen, culminating in his leadership of a rapid Konoha military mobilization against Cloud Village. 34 36 38

Ocular Evolution and the Little Ten-Tails

Following an unsuccessful attempt to force his own Mangekyō awakening, Yansheng discovers and cultivates the Little Ten-Tails. He uses it to create artificial Mangekyō Sharingan, synthesize a Tenseigan in clone bodies, and begin pursuing an Ōtsutsuki-like evolution while keeping his original body as experimental material. 45 48

Return to Konoha

After two years away, Yansheng returns to Konoha with pale-blue eyes and a reputation as a Konoha hero. He discovers that Itachi has remained trapped in a modified Izanami for the entire period and personally releases him. 50

Notable Quotes

“In fact, you really would!” 10

“As long as no one can harm me or anything I care about around me, that's enough.” 30

Trivia

• Yansheng’s deliberate attempt to awaken his own Mangekyō Sharingan fails; the failure instead leads to the discovery of the Little Ten-Tails. 45 46
• His original Three-Tomoe Sharingan is restored after he seals the unstable Byakugan-derived power within his body. 26
• He regards conventional morality as inapplicable to his research, though he initially requests condemned criminals rather than arbitrary civilians as experimental subjects. 15 30
• He returns to Konoha at age thirteen after being absent for two years. 50
