Fang Xu

Biodata

Power Progression

Background

Fang Xu is the orphaned son of Fang Naoto, a deceased Konoha jōnin, and a mother who also died on a mission. His family records identify him as a descendant of a Senju branch that adopted another surname after integrating into Konoha’s ordinary household system. He later deduced this heritage from the Thousand Hands Swordsmanship Insights left by his parents. 26 29

Root’s investigation identifies his father as a former Anbu jōnin and his mother as Tawara Keiko, an ordinary chūnin. Tsunade confirms that his grandfather belonged to the Senju clan, whose branches abandoned their surname and integrated into village life during Tobirama Senju’s era. 38 42 70

Fang Xu’s consciousness originates from Earth. Upon awakening in the Naruto World, his previous-life memories merged with those of the orphaned Academy student. The fusion of the two souls strengthened his mental foundation, while his knowledge of the original story informed his efforts to avert future tragedies. 1 28 30 151

Before his rapid growth, he was viewed as an unremarkable Ninja Academy student with average chakra, ninjutsu talent, and taijutsu. Kakashi considered his appearance his only notable quality. 7

After consuming the Rumble-Rumble Fruit, Fang Xu began secretly combining Devil Fruit power, lightning-nature chakra, body tempering, swordsmanship, and inherited cross-world experiences. He deliberately trained in isolated locations to avoid exposing his abilities and focused on building a body capable of supporting his growing power. 4 18

Appearance

Fang Xu has short silver hair, pale eyes, and a face that Hatake Sakumo considers somewhat reminiscent of the Second Hokage. Kakashi privately regards him as one of the few classmates who can compete with him in looks. 7 45

• Short, silver-white hair. 45
• Pale eyes and facial features noted to resemble Tobirama Senju’s. 45
• Frequently underestimated because of his youth despite possessing overwhelming combat ability. 112 144
• His outwardly childlike appearance conceals physical strength far beyond an ordinary person’s; Nazi immediately notices this discrepancy during their reunion. 221

Personality

Fang Xu is methodical, pragmatic, and intensely focused on sustainable growth. He refuses to force training when his chakra or body is exhausted, treats food and recovery as necessary cultivation resources, and uses the Attribute Panel to verify that every training method is effective. 6 21 48

He is highly secretive about the origins of his power. Even when questioned by mentors and allies, he usually provides only enough information to preserve trust without exposing the Exchange Talent or his cross-world resources. 136 144 171

Despite his calculated nature, Fang Xu is fiercely loyal to those who support him. He sees Hatake Sakumo as both a teacher and a caring elder, resolves to prevent Sakumo’s tragic fate, and reacts violently when Kimura condemns the man who saved him. 28 60 61

He has a sharp tongue and strong social instincts. He defused Asuma’s possessive challenge through principle rather than violence, diplomatically refused Might Duy’s green jumpsuit, and regularly uses humor to embarrass Obito or ease tension. 8 17 56

His caution extends to unfamiliar powers and worlds. He refuses to take Nazi across worlds before establishing that passenger travel is safe, and postpones activating his random transmigration plugin because its destination could contain beings capable of killing him immediately. 222 328

Fang Xu views political suppression without sufficient strength as fundamentally unsustainable. He feels no sympathy when Hiruzen and Danzō’s restrictions on his battlefield participation provoke resentment, and argues that substantial war reparations should rebuild Konoha while weakening defeated enemies’ ability to restart hostilities. 307 340

Abilities & Skills

Exchange Talent

Fang Xu’s Exclusive Talent enables exchanges with other worlds, allowing him to acquire abilities, items, knowledge, bloodlines, and system components.

• Reached Level 2 after his tenth exchange, reducing the cooldown from once every seven days to once every three days. 74
• Reached Level 3, allowing him to accumulate exchange attempts and spend multiple attempts to revisit previously contacted worlds. 138
• Gains improved odds of obtaining rare abilities, bloodlines, resources, and high-value items after the upgrade. 138
• Uses cross-world exchanges to obtain major power sources, including Devil Fruits, Haki, Psychic techniques, cultivation methods, and technological equipment. 168 279 299
• Treats exchanges strategically rather than spending attempts immediately, saving them for targeted worlds and higher-value opportunities. 148
• Exchange optimization can remove an acquired ability’s original restrictions or flaws, as demonstrated by the world-travel plugin’s removal of Fortune Point requirements and the Six Treasury Immortal Thief’s corrected consumption requirements. 328 343

Rumble-Rumble Fruit and Lightning Release

Fang Xu’s primary combat system combines the Rumble-Rumble Fruit with lightning-nature chakra, Lightning Mode, body tempering, swordsmanship, and electromagnetic control.

• Elementalization — Converts his body into lightning; initially limited to ten seconds, then extended to fifteen seconds through conditioning. 4 18
• Lightning Activation / Lightning Mode — Uses electrical stimulation to enhance muscles, nerves, speed, reaction time, and striking force. 10 23
• Lightning Body Tempering — Gradually reinforces body parts through controlled lightning stimulation; he avoids the brain and internal organs until sufficient control is established. 15 18
• Lightning Assault — Short-range burst movement that lets him cross several meters almost instantly, though early control and range were poor. 4
• Thunder Bird, Thunder Beast, and Thunder Dragon — Lightning constructs whose scale and destructive power improved dramatically after his physique was strengthened. 4 111
• Thunder God — A giant lightning transformation capable of destroying a mountain over fifty meters tall; after Lucci’s physical legacy, it consumes roughly one-quarter of his stamina and chakra rather than half. 111
• Raigo — A weather-dependent lightning technique requiring cloud control and Fang Xu’s special lightning foundation; he warns Kakashi that ordinary Lightning Release users cannot safely imitate it. 131
• Railgun — Electromagnetic long-range bombardment used from the air; it devastated Kirigakure’s retreating army and became central to his battlefield reputation. 155
• Electromagnetic forging and metal control — Melts and reshapes kunai into custom short swords, recalls weapons through electromagnetic force, and later turns Rasa’s Gold Dust into thousands of Flying Thunder God-marked blades. 187 304
• Teaches full and simplified versions of Lightning Body Tempering to Sakumo and Kakashi respectively, sharing a method intended to raise their long-term physical potential. 78

Swordsmanship and Thunder Breathing

Fang Xu began as a self-taught swordsman using Senju insights, then developed an increasingly integrated lightning sword style under Hatake Sakumo’s guidance.

• Built his initial foundation through footwork, breathing, distance control, force generation, and timing rather than flashy techniques. 6 23
• Developed Lightning-Attribute Ninja Swordsmanship by integrating lightning into his footwork, breathing, body movement, and sword rhythm rather than simply coating a blade in chakra. 40
• Gained Kaigaku’s experience in Thunder Breathing Forms Two through Six and successfully learned the First Form, Thunderclap and Flash, which Kaigaku could not master. 37
• Later inherited Hawk-Eye’s complete Kendo experience, including Great Swordsman-level Flying Slashes; even without chakra, he can cut iron and cleave massive boulders from hundreds of meters away. 168
• Created an advanced Kendo cultivation method focused on breathing, physical conditioning, force generation, slash condensation, and sword intent. 214 215
• Links swordsmanship with Flying Thunder God, Geppo, Rasengan, lightning, and Psychic perception to attack continuously from changing spatial coordinates. 187
• Can split a massive Complete Susanoo head-on; Madara recognizes his swordsmanship and integrated combat system as far beyond ordinary Kage-level strength. 199 213
• Uses Mental Strength and Observation Haki to detect Limbo shadows, then strikes them with Myriad Transformations coated in lightning, Armament Haki, and Conqueror’s Haki. 264

Six Powers and Life Return

By absorbing Rob Lucci’s crystal, Fang Xu gained complete mastery of the Six Powers and a greatly enhanced physical foundation.

• Soru — Explosive ground movement without hand seals or Lightning Release assistance. 110
• Geppo — Midair movement and maneuvering. 110
• Rankyaku — Ranged air slashes capable of cleaving stone. 110
• Shigan — Penetrating finger strikes that can pierce solid rock. 110
• Tekkai — Muscle hardening that grants high resistance to ordinary weapons. 111
• Kami-e — Evasive movement that lets his body flow with attacks and air currents. 111
• Rokuogan — An invisible shockwave powerful enough to crack the ground. 111
• Life Return — Conscious control over muscles, organs, hair, physique, and digestion; Fang Xu uses it to conceal rapid growth and regulate his developing body. 110 112
• Later employs Life Return to regulate individual muscle bundles, heartbeat, and blood flow while combining bodily control with nutrient absorption and Armament Haki tempering. 344

Haki and Additional Devil Fruits

Fang Xu later gained Whitebeard’s complete Three-Color Haki experience and consumed the Dark-Dark Fruit and Tremor-Tremor Fruit without their standard weaknesses.

• Observation Haki — Combines with Psychic perception, electromagnetic sensing, and Mantra to extend his detection range to approximately ten kilometers. 168
• Armament Haki — Reinforces his body and Chakra Longblade; advanced use remains limited by his immature physique. 168
• Conqueror’s Haki — Overwhelms nearby creatures and attacks an opponent’s mind and will directly; Fang Xu used it to establish dominance over Orochimaru. 168 247
• Conqueror’s Haki Infusion — Can coat his blade with black-red arcs of infused Haki, though possessing inherited experience does not initially make his body capable of sustaining every advanced application. 168
• Dark-Dark Fruit — Creates darkness with gravitational pull capable of dragging in rocks, trees, metal tools, chakra techniques, and spiritual energy. 169 170
• Tremor-Tremor Fruit — Generates and compresses vibration force for devastating strikes and body-tempering research. 171 176
• His Devil Fruit weaknesses were removed, including vulnerability to seawater and Seastone, the Dark-Dark Fruit’s amplified pain, and the danger of eating multiple Devil Fruits. 168
• Uses the Dark-Dark Fruit to refine distinct powers into origin energy, including energy that deeply reinforces his bones and marrow through Shikotsumyaku. 254
• By his later cultivation research, can direct Armament Haki beneath the skin into muscles, bones, and organs as part of a combined body-tempering system. 344

Psychic and Medical Abilities

Fang Xu possesses advanced Psychic techniques alongside formal Medical Ninjutsu training under Tsunade.

• Teleport — Can teleport up to ten kilometers inside the Spatial Ring; mental interference, spatial distortion, energy shielding, and sealing barriers can disrupt it. 147
• Mind Reader — Reads basic thoughts and emotions, tested on ninja beasts and Shadow Clones. 147
• Hypnosis — Easily affects weaker creatures but faces resistance from trained ninja. 147
• Petrification Technique — Temporarily immobilizes targets by suppressing mental and physical responses. 147
• Heal Pulse — Ranged healing suited to battlefield support, used alongside Mystical Palm Technique and Viridian Force. 147
• Great Expansion Art — Improves perception and divided-mind control, allowing him to manipulate numerous objects independently. 231
• Studied anatomy, chakra pathways, pharmacology, trauma treatment, and Medical Ninjutsu through Tsunade’s intensive curriculum. 54 60
• Viridian Force — Gentle life energy that repairs injuries, gradually heals hidden damage, restores stamina, and soothes the mind without the same precision requirements as Mystical Palm Technique. 123
• Possesses the Kureha Medical System and Chakra-Enhanced Strength Technique alongside battlefield first aid and Mystical Palm Technique. 123
• Gains practical treatment experience under Chiba Miwa, including cleaning contaminated wounds and applying controlled Medical Chakra to injured shinobi. 87 88

Space-Time Ninjutsu and Sealing

Fang Xu combines powerful perception, sealing knowledge, and Flying Thunder God formulas into a highly mobile combat and logistics system.

• Mastered the first stage of Flying Thunder God using specially forged short swords as coordinates. 187
• Learned the second stage, allowing him to leave formulas on objects, terrain, tools, animals, and enemies. 187
• Can teleport nonliving objects, using Flying Thunder God to transport thousands of marble slabs to his construction site. 215
• Ordered more than one hundred Shadow Clones to establish hidden Flying Thunder God markers across major regions and routes of the Shinobi World. 200
• Began learning the Spirit Transformation Technique, briefly separating his spirit from his body; the technique leaves his body defenseless while active. 201 203
• Flying Thunder God short swords also function as emergency signals: injecting chakra into a formula allows him to sense it, although he does not promise an immediate response in every circumstance. 247
• Freezes Rasa and seals his chakra, and later seals Yugito’s chakra before she can complete her Tailed Beast Transformation. 304 337
• Acquires spatial magic with the Ancient One’s accumulated casting experience, enabling spatial folding and an isolated space suited to experimentation, defense, infiltration, and trapping enemies. 285

Beast Taming and Soul Contracts

Fang Xu’s Beast Taming Space and later forced-contract ability support both companion development and covert operations.

• Beast Taming Space — Initially measures approximately one hundred meters in diameter, permits environmental adjustment, and stores contracted beasts. 85
• Provides tenfold growth, hatching, adaptation, and evolutionary advancement; its accelerated development is useful for beasts and later cultivation resources. 85 328
• Contracted beasts can feed their power back to Fang Xu, while his chakra, physique, and bloodline development can benefit them in return. 85
• Forced soul contracts — Can forcibly contract lifeforms one rank below himself if they lack special soul protection. Targets within two ranks above him can also be contracted after their resistance is broken. 137
• Uses soul-bound agents to infiltrate hostile organizations and gather intelligence rather than merely eliminating every enemy operative. 138 139

Bloodline and Body Cultivation

Fang Xu’s Senju heritage, medical regeneration, body-tempering systems, and later bloodline acquisitions support his immense collection of abilities.

• His Senju bloodline initially awakened, granting increased vitality and improved chakra affinities. 123
• His Senju bloodline later fully awakened, producing Wood Release through the fusion of Water and Earth chakra. 210
• Developed a self-tempering method that combines vibration to strengthen bones and organs, lightning to reinforce muscles and nerves, and healing abilities to repair controlled damage. 171
• Organizes body cultivation into six realms: Body Tempering, Tendon Forging, Bone Forging, Organ Refinement, Blood Renewal, and Marrow Transformation. 255
• Can simultaneously use Ice Release, Shikotsumyaku, and the Three-Tomoe Sharingan for battlefield control, close-range offense, and predictive observation. 254
• Shikotsumyaku strengthens his skeleton and bone marrow as well as providing bone manipulation, improving bone density, blood production, and cellular vitality. 254
• Regards Marrow Transformation, the sixth body-cultivation realm, as the stage at which a cultivator can break the limitations of a mortal lifespan and attain an extraordinary body. 255
• His complete Sage Body is a fully integrated life system rather than an incomplete physique produced by transplanting Hashirama Cells. The Slug Sage confirms that his cellular energy, mental strength, and chakra exceed ordinary human limits. 275
• Uses Wood Clones for surveillance and information gathering, including monitoring Uchiha movements and maintaining responsibilities while his main body trains. 248 281

Senjutsu and Immortal Dao Cultivation

Fang Xu develops a cultivation path by comparing chakra, senjutsu, orthodox immortal cultivation, mental training, and body-refinement methods.

• Learns Shikkotsu Forest Senjutsu directly from the Slug Sage, including Natural Energy perception, absorption, three-energy balance, and safeguards against loss of control. 275
• Azure Essence Sword Art — Provides orthodox Qi Refining methods and meridian circulation routes. His strengthened, unobstructed meridians allow rapid initial advancement. 278 279
• Three-Turn Heavy Essence Art — Cultivated alongside the Azure Essence Sword Art to refine spiritual energy and combine Spiritual Power with chakra as True Essence Mana. 279
• Complete Sage Art — Stably refines and stores Natural Energy, removing dependence on maintaining a temporary Sage Mode and allowing that energy to strengthen the body. The Slug Sage recognizes him as the first true human sage. 280 281
• Requires Tsunade, Nazi, and Kurenai to master Basic Sage Mode before he teaches them the Complete Sage Art. 281
• Six Treasury Immortal Thief — An exchange-perfected inheritance from Ruan Feng that breaks down useful substances and energy into qi. Food, medicinal herbs, minerals, and various energies can serve as resources without requiring human consumption. 343
• The Six Treasury Immortal Thief improves digestion, recovery, physique, vitality, and resistance to aging; its Six Bowels Cycle produces qi that gathers at his middle dantian. 343
• Develops stable reverse conversion from qi into life energy, distributing nourishment through blood, organs, muscles, bones, and cells without forcibly extracting their internal energy. 344
• Combines the Six Treasury Immortal Thief’s absorption, Life Return’s bodily control, Armament Haki tempering, and stored lightning while continuing to seek a more complete essence-refining system. 343 344

Independent World Travel

Fang Xu gains an independent means of world travel after acquiring a transmigrator system’s world-travel plugin.

• The optimized plugin accepts any energy source and passively recharges, rather than requiring its original Fortune Points. 328
• Integrates with the Attribute Panel, which displays its accumulated energy; both chakra and Viridian Force can recharge it. 328
• Initial random travel selects an unknown destination from the myriad worlds. Successful arrival automatically records that world’s coordinates. 328
• Can expend energy to travel freely between worlds whose coordinates have been recorded through actual arrival. 328
• Cross-world projections seen during exchanges do not count as visits and cannot supply usable coordinates to the random transmigration plugin. 344
• Delays its first activation while prioritizing Immortal Dao cultivation and assessing the danger of arriving in an unknown high-level world. 328

Equipment / Weapons / Items

• Chakra Longblade / Eight-Sided Han Sword — A custom sword from Tenten’s shop that conducts Lightning Release Chakra exceptionally well and enhances his swordsmanship. 111
• Flying Thunder God Short Swords — Personally forged double-edged short swords bearing his custom spatial formulas; usable for both throwing and close combat. 187
• Myriad Transformations — A blade wielded against Madara’s Limbo shadows and coated with lightning, Armament Haki, and Conqueror’s Haki. 264
• Spatial Ring — A god-tier storage item that preserves cooked food and temperature; it also serves as a private training and research space. 136
• Spatial Bracelets — Dark-silver bracelets containing batteries as external power sources for lightning techniques and chakra-infused swordsmanship. 111
• Gourmet Tablecloth — Produces ordinary meals and medicinal cuisine, eliminating his nutritional bottleneck for intensive body tempering. 48
• Gravity Training Room — A gravity-control device used alongside Lightning Body Tempering; Fang Xu trained under tenfold gravity until his body reached its limit. 299
• Attribute Panel — A monitoring tool that records progress in chakra control, body tempering, Lightning Release, and swordsmanship without directly granting power. Later incorporates the world-travel plugin and its energy display. 21 328
• Arceus Invitation — A cross-world invitation associated with his journey to the Pokémon World; he presents it to Nazi when explaining his origin and initially investigates whether it can safely transport passengers. 221 222
• Spirit Stones and cultivation jade slips — Resources and inheritances used to cultivate the Azure Essence Sword Art and Three-Turn Heavy Essence Art. 278 279
• Azure Bamboo Cloudswarm Sword inheritance — A flying-sword legacy optimized to relax its original material restrictions and retain growth potential. Fang Xu initially postpones forging it because his cultivation and materials are insufficient. 278 279
• Void Sphere — Used to receive half of Kokuō’s chakra reserves after Iwagakure’s surrender. 333
• Tailed beast chakra samples and Ten-Tails fragment — Research materials sealed separately within the Spatial Ring; Fang Xu still seeks Nine-Tails chakra through Tsunade’s mediation with Kushina. 340

Relationships

• Hatake Sakumo — Swordsmanship teacher, protector, and father figure. Fang Xu becomes Sakumo’s disciple after sparring Kakashi and later resolves to prevent the White Fang’s tragic fate. He teaches Sakumo Lightning Body Tempering and visits him after the war as the acknowledged strongest shinobi. 25 28 78 349
• Hatake Kakashi — Closest rival, sparring partner, fellow disciple of Sakumo, and frequent mission companion. Their competition drives both of them to improve. Fang Xu teaches him simplified Lightning Body Tempering and promises to develop suitable S-rank Lightning Release techniques once his foundation improves. 23 26 78 131 148
• Tsunade — Medical Ninjutsu mentor and protective elder. She accepts him as a disciple after recognizing his chakra control, medical talent, Senju lineage, and maturity. She acknowledges him as family before the formal apprenticeship and asks Jiraiya and Orochimaru to protect him during her absence. 29 42 54 71
• Kurenai Yuhi — Former deskmate, close companion, Team 10 student, and open admirer. She regularly worries for him, maintains his home during his absence, and states that she hopes to marry him when she grows up. By Team 10’s first meeting, she already lives at his estate; Fang Xu tells her to wait until adulthood. 121 203 289
• Might Duy and Might Guy — Early taijutsu contacts who agree to guide Fang Xu; he later gives both Flying Thunder God short swords for emergency protection. He intervenes against the Seven Ninja Swordsmen of the Mist and sends Duy to escort Guy and his surviving teammates home while he confronts the Six-Tails. 6 299 319
• Obito Uchiha — Classmate and frequent comedic target. Fang Xu values their connection partly because Obito’s hair has proven useful in exchanges. His influence helps redirect Obito toward taijutsu and enthusiastic training, disrupting Madara’s intended development of him as an agent. 8 54 142 248
• Pikachu — Loyal electric companion trained inside the Beast Taming Space; assists in combat, camp defense, and reconnaissance. 120 136
• Nazi — Psychic ally and fellow cultivator who helps assess Fang Xu’s mental development and supports his plan to create a human-compatible senjutsu system. He previously saved her from Psychic backlash by absorbing leaked source power; after their reunion, she helps obtain a local identity and nearby villa for him. They maintain a mental link, and he protects her from Danzō’s attempted seizure. 221 222 231 235 236 246 271
• Orochimaru — A wary collaborator. Fang Xu uses Conqueror’s Haki and strict conditions to prevent experimentation while offering life-extension research in exchange for cooperation. After witnessing his later battlefield power, Orochimaru considers trading research on immortality, souls, and Kekkei Genkai for access to his cultivation system. 247 304 307
• Shimura Danzō — Political enemy who repeatedly attempts to control, investigate, isolate, or assassinate Fang Xu; Fang Xu counters by turning Root operatives into undercover assets. He later forces Danzō to kneel after an attempt to seize Nazi and warns him against targeting his friends. 138 139 183 236
• Hiruzen Sarutobi — Initially invests in Fang Xu’s development, but later restricts his frontline participation out of concern for the prestige and political influence he and Sakumo could accumulate. Fang Xu openly criticizes these decisions and challenges Hiruzen’s reluctance to demand substantial reparations after victory. 14 161 183 282 340
• Minato Namikaze and Kushina Uzumaki — Trusted benefactors who support his Flying Thunder God studies. Fang Xu resolves to prevent their deaths during the future Nine-Tails crisis. He later fights alongside Minato against Iwagakure and seeks Kushina’s cooperation in obtaining Nine-Tails chakra. 151 187 333 340
• Shinku Yuhi — Early team leader and Kurenai’s father. Initially suspicious of Fang Xu’s closeness to his daughter, he becomes more approving after observing Fang Xu’s decisive judgment and protection of Kakashi during bandit-suppression missions. 87 104 115 120
• Uzuki Yugao and Shizune Kato — Team 10 students. Fang Xu promises Yugao advanced swordsmanship if she completes his training and offers Shizune medical guidance and a possible apprenticeship under Tsunade if she meets his standards. 289
• Madara Uchiha and Black Zetsu — Strategic enemies whose plans are increasingly disrupted by Fang Xu’s influence and military victories. Madara recognizes his potential after fighting through a disposable White Zetsu body, while Black Zetsu later warns Uchiha En that confronting Fang Xu would be suicidal. 157 199 213 325
• Fugaku Uchiha and Hizashi Hyuga — Clan figures who recognize his potential to alter Konoha’s political balance. Fugaku considers securing his support for the Uchiha, while Hizashi sees his strength as capable of challenging the Hyuga Main Family’s rules. 260 261 327
