Background

Yuan is a transmigrant who resolved to preserve his second life in the war-torn shinobi world. His parents, Uchiha Fusan and Uchiha Mizhu, died during the Third Shinobi World War, leaving him without close blood relatives; Fugaku later treated him as a nephew and political investment for the clan. 3 12 35

Before the war, Fugaku arranged for Yuan to become Orochimaru's student. The laboratory offered him protection from the battlefield, but Orochimaru's experimentation on captives made Yuan wary of his teacher and determined to conceal his own discoveries. 3 4

Yuan's cells possess a unique ability to devour and fuse genetic material from other species. Seeking enough strength to avert the Uchiha Clan's future destruction, he infiltrated Mountain Graveyard, impersonated Obito, stole a fragment of the Demonic Statue of the Outer Path, and seized Madara's collection of ninjutsu, forbidden techniques, and research records. 1 2

Personality

Yuan is cautious, analytical, and intensely self-reliant. Early in his career, he hides his abilities from Orochimaru, Konoha, Obito, and even most allies because he considers information a ninja's lifeline. 2 3 4

His caution does not make him passive. Yuan repeatedly accepts dangerous opportunities—intercepting Obito, confronting Tailed Beasts, fighting Kage-level opponents, and collecting dangerous bloodlines—when the potential reward advances his plans. 1 13 27 180

He is willing to manipulate, possess, kill, and impersonate others to eliminate threats or acquire power. However, he also seeks to protect the Uchiha Clan, improve the lives of Jinchūriki and bloodline clans, and prevent wars from further harming ordinary civilians. 58 112 144 177

Abilities & Skills

Gene Devouring and Fusion

Yuan's defining ability allows his cells to fuse with the genes of other species and preserve much of their original power.

• Can inherit bloodlines, Kekkei Genkai, ocular powers, and traits from acquired genetic material. 3 45
• The fusion process can temporarily prevent further genetic devouring. 3
• He uses Gene Fusion to acquire the Kurama Clan's genjutsu bloodline, Mangekyō abilities, Tenseigan, and Otsutsuki-derived traits. 45 62 163 186
• Repeated fusion carries the risk of accelerated aging and reduced lifespan, though he later offsets this through Otsutsuki Kaguya's genes. 138 186

Demonic Statue of the Outer Path Gene

After fusing with the Demonic Statue's genes, Yuan gains immense physical vitality, Chakra capacity, and learning aptitude.

• Performs self-healing without hand seals. 3 6
• Possesses Chakra affinity for Yin, Yang, Water, Wind, Fire, Earth, and Lightning Release. 27
• Learns A-rank and forbidden techniques at exceptional speed. 3 13
• The associated statue fragment can absorb Chakra, including Tailed Beast Chakra. 2 27
• The fragment can be controlled by Yuan after he severs its connection to Obito's statue. 4

Spiritualisation Technique

Orochimaru teaches Yuan the S-rank Spiritualisation Technique, which Yuan masters almost immediately.

• Separates his soul from his body for reconnaissance, combat, and Chakra analysis. 13 17
• Can move directly toward sensed Chakra signatures. 13
• Uses Soul Possession to invade and control another person's body. 13 58
• Uses the technique to enter mental spaces and examine soul-bound seals such as the Caged Bird Curse Mark. 130
• Its effectiveness is amplified by Yuan's unusually strong soul, which he suspects is related to transmigration. 12

Genjutsu and Illusion Space

Through the Kurama Clan's bloodline, Yuan can construct highly realistic illusionary environments and directly manipulate a target's senses.

• Can cast genjutsu through gestures, speech, or images without hand seals. 45
• Creates Illusion Spaces suitable for interrogation, torture, battle simulation, and training with Shadow Clones. 45
• Uses Phantom Lotus Kill to disrupt Isobu and interfere with enemy sealing operations. 22
• Can immobilize entire populations in genjutsu; he traps Kumogakure's villagers and ninja inside an Illusion Space after killing the Fourth Raikage. 121
• Uses enhanced genjutsu to suppress Obito's Mangekyō abilities and trap him in the Kamui Dimension. 72

Mangekyō Sharingan and Dōjutsu

Yuan eventually awakens and collects several high-level ocular powers.

• Takamagahara — his left Mangekyō eye contains nine Mangekyō abilities. 62
• Yomotsu Hirasaka — his right Mangekyō eye nullifies ocular powers. 62
• Kamui — obtained through Dual Kamui fusion; permits spatial phasing and dimensional movement. 123 151
• Toyoashihara — acquired from Fugaku; allows him to observe causal connections and investigate past events. 153 194
• Tenseigan — enables direct manipulation of souls and spiritual energy, enhanced Chakra control, and Yin–Yang Release. 163
• He later possesses both Tenseigan and Rinnegan ocular power, allowing him to draw the Sun and Moon Runes to himself. 188

Susanoo and Sage Techniques

Yuan can manifest a golden Susanoo, later described as a crimson-gold sword-bearing warrior.

• Uses Susanoo to intercept a Tailed Beast Bomb and end the war against Kumogakure. 90
• His “Beast of Prey” Susanoo shell withstands attacks from the Two-Tails. 87
• Can use Sage Mode in battle against the Madara of another world. 151
• Employs Hashirama Cells Inner Armor to enhance Uchiha shinobi and raise their combat potential. 79 116

Shinjutsu and Ancient Inheritances

Yuan investigates powers left behind by Otsutsuki Shibai, whom he considers essential to confronting stronger Otsutsuki.

• Obtains the Demon Country Priestess's ocular inheritance and sealing technique. 200
• Instantly masters the Mysterious Peacock Method in Bear Country. 201
• Absorbs a Shibai-linked meteorite's power and gains the ability to manifest imagination. 202
• Understands that rule-level Shinjutsu can only be countered by Shinjutsu. 199

Relationships

• Orochimaru — Yuan's teacher and former squad leader. Yuan respects Orochimaru's knowledge but conceals his Gene Fusion ability and remains wary of his ambitions. 3 4 13
• Uchiha Fugaku — Yuan's uncle and the Uchiha Clan head. Fugaku supports Yuan's plans to strengthen the clan and increasingly trusts his vision for its future. 35 65 112

• Uchiha Izumi — Yuan's adopted younger sister and student. He teaches her shuriken techniques and monitors her Sharingan development. 39 45 46

• Obito Uchiha — Yuan's early adversary and source of stolen legacy, statue fragments, and Kamui-related power. Yuan later traps him in the Kamui Dimension through genjutsu. 1 72
• Black Zetsu — a manipulative temporary partner and mutual observer. Yuan bargains for Black Zetsu's Mangekyō material while recognizing his connection to Kaguya and long-term schemes. 72 149
