History

Yuzhen discovered that his body could assimilate White Zetsu. The process granted him White Zetsu techniques, regenerative traits, and permanent improvements to his chakra and physique; he consequently began treating White Zetsu as “Experience Packs.” 9 12

After developing Water Style under Tobirama Senju, Yuzhen left the forest camp and began acting independently. He infiltrated Tsuchishi’s experimental facility, defeated its master, rescued Hagane Chihori, and freed other captive ninja while concealing his clan connection to Chihori. 23 28

Yuzhen built alliances around the Fūma Clan, securing Fūma Kotarō’s loyalty through a blood-sharing pledge and expanding what became the Firefly Organization. When Kikyo Castle moved against his people, he struck first, defeated the Earth Grudge Fear user Jiongu Lu, and seized control of the situation around Kikyo Castle. 38 58 60 64

His conflict with Jiongu Lu forced the awakening of Boil Release. The battle established a pattern in Yuzhen’s growth: he endured severe damage, studied an opponent’s abilities, then used absorption, adaptation, and an unexpected technique to reverse the fight. 59 61

As Firefly’s leader, Yuzhen preferred recruitment and integration when practical. He defeated Akimichi Jinsei in a duel intended to settle a war without annihilating the Akimichi Clan, then sought to build an Ino–Shika–Chō-style unit around the organization. 84 90

Xiao Qi’s uncontrolled summoning eventually brought Yuzhen into conflict with Kinshiki Ōtsutsuki. Unable to defeat Kinshiki, he was sent by Xiao Qi into the distant era before the Ninja World’s founding, where he spread chakra among a doomed tribe and later became the Sage of Six Paths’ student under the name Gan. 188 191 192

After centuries of study, Yuzhen founded the Uzumaki Clan, entrusted it with the Sage of Six Paths’ remains, and entered eternal slumber on the moon. Upon awakening, he pursued Sage Mode, Truth-Seeking Balls, and the teachings of Hamura Ōtsutsuki while preparing for renewed Otsutsuki threats. 199 206 208

Personality

Yuzhen is generally soft-spoken, rational, and outwardly gentle, but his restraint does not prevent decisive violence. He can be merciful toward defeated enemies and captives, yet he is willing to exploit White Zetsu, manipulate allies and rivals, and use outsiders as experimental risks when doing so advances his goals. 28 43 79

He is intensely focused on growth and treats power as a practical problem to be solved. Although he recognizes the limits of his talent and chakra foundation, he continuously searches for methods to compensate through bloodline abilities, research, allies, and stolen resources. 60 73 135

Yuzhen values long-term stability more than conquest. He promotes organizational growth, clan survival, and alliances, but his version of peace is backed by overwhelming strength, calculated intimidation, and a readiness to remove threats. 149 161 199

Abilities & Skills

White Zetsu Assimilation

Yuzhen can assimilate White Zetsu chakra and traits, making White Zetsu his primary source of permanent growth.

• Gains improvements to physique, chakra quantity, chakra quality, and recovery through absorption. 12 71 105
• Can absorb chakra in combat through the Spore Technique, strengthening himself while weakening opponents. 61
• Benefits vary by White Zetsu type; some provide elemental affinities, while others improve base attributes, sensing, or control. 12 71
• Uses White Zetsu corpses and chakra as research material, fuel, and sacrifices for high-level techniques. 71 112 197

White Zetsu Transformation

His partial or full White Zetsu transformation allows infiltration, regeneration, and biological adaptation.

• Mayfly Technique — Moves through earth and rock, enabling silent infiltration and escape. 10

• Substitute Technique — One of the practical White Zetsu techniques he acquired. 9
• Genjutsu resistance — White Zetsu transformation can help him break free from genjutsu. 30
• Regeneration — White Zetsu tissue rapidly repairs burns and other injuries, though healing consumes chakra. 59
• Limit: Mayfly cannot be activated safely in intense combat; merging through a wall takes roughly four to five seconds and leaves him exposed. 59

Chakra Natures and Kekkei Genkai

Yuzhen combines conventional elemental training with mixed-nature bloodline abilities.

Medical Ninjutsu and Yin-Yang Release

Yuzhen’s healing developed from White Zetsu regeneration, medical ninjutsu, Yang Release, and eventually Yin-Yang Release.

• He can treat severe injuries and repair damaged tissue with exceptionally gentle chakra control. 105 144
• Yin-Yang Release allows him to create living forms and restore others on a massive scale. 192 207 216
• He saved both allied and enemy ninja from near death during a battlefield intervention. 216

Yuzhen possesses multiple high-level ocular and spatial abilities.

• Byakugan — Enhances perception, exposes stealth, and allows him to read and counter Dust Release attacks. 231
• Byakugan-based Space-Time Ninjutsu — Enables phasing, unrestricted-distance spatial movement without coordinates, and access to a personal storage dimension. 203 205
• Mangekyō Sharingan — Manifested after reconnecting with Xiao Qi. 202
• Yomotsu Hirasaka — A further-developed space-time application confirmed after acquiring Urashiki Ōtsutsuki’s power. 239

• His restored chakra quality eventually surpassed Hashirama Senju’s by Hashirama’s assessment. 203

Combat and Leadership

• Uses kunai, explosive tags, chakra weapons, and clones alongside ninjutsu. 59 165
• Is capable of elite jōnin-level combat after his White Zetsu-derived improvements, though he remains conscious of the gap between elite ninja and true Kage-level opponents. 105
• Defeated Jiongu Lu, Ishiwa Suijin, Akimichi Jinsei, and the First Tsuchikage through unconventional tactics and superior versatility. 61 84 164 231
• Designs terrain traps, misinformation campaigns, and force deployments to defeat numerically superior enemies. 162 165

Equipment / Weapons / Items

• Unsharpened Sword · Reed — A heavy longsword acquired from Hozuki Kannazuki; better suited to Yuzhen’s straightforward weapon handling than the longer Chakra Blade. 107 108

• Kunai and Explosive Tags — Standard tools used for ambushes and pressure during combat. 59

• Earth Grudge Fear seedlings — Cultivated and refined as part of his research into the secret technique. 79 82

Relationships

• Uchiha Nanami — Ally, adviser, and Firefly Organization member. Their relationship grows from mutual caution into trust; she helps protect his forces and entrusts future plans to him. 43 71 117
• Fūma Kotarō — Fūma Clan leader and close subordinate. Their blood-sharing pledge secured the Fūma Clan’s allegiance, and Kotarō later assists with research, arms dealing, and military planning. 38 79 82
• Tobirama Senju — Teacher, collaborator, and rival in technical development. Tobirama taught Yuzhen Water Style, while Yuzhen helped inspire and develop Tobirama’s Flying Thunder God Technique. 23 95
• Hashirama Senju — Political ally and later companion in Otsutsuki-level conflicts. Hashirama recognizes the extraordinary quality of Yuzhen’s restored chakra. 171 203

• The Sage of Six Paths — Teacher and mentor. He accepts Yuzhen, then known as Gan, as a disciple and teaches him Yin-Yang Release. 191 192
• Orochimaru — Temporarily allied researcher from the future. Yuzhen treats him and assigns him Hashirama Cell research after Orochimaru’s arrival. 180
• White Zetsu — Both enemy network and indispensable resource. Yuzhen hunts, studies, controls, and consumes them to fuel his growth. 12 82 136

Notable Quotes

“Why? Honestly, I don't know why either.” 12

“The most important mission of a clan is to continue.” 199

Trivia

• Yuzhen explicitly views White Zetsu as “Experience Packs,” “Fuel Packs,” and useful research material. 9 112
• He considers White Zetsu a preferable path to power over immediately transplanting Earth Grudge Fear into himself, partly because he dislikes extensive bodily modification. 73
• Despite his high-level ninjutsu, he is a poor conventional swordsman; Hatake Sakumo could defeat him soundly in a ninjutsu-free spar. 145
• He founded the Uzumaki Clan but rejected his eldest grandson’s proposal to rename it after him. 199
