Background / History

Su Hang was transmigrated into Windmill Village with no money, weapon, or identity. After driving off a wild boar with stones, he awakened the Myriad Worlds Fusion System and learned that he was a “Zero Variable,” capable of altering predetermined causality at the cost of escalating world correction. 1

At Makino’s tavern, Fortune Perception led him to Shanks’ wooden crate. The system identified its contents as the Mythical Zoan Nika Fruit, whose destined recipient was Luffy. Su Hang exploited Benns’ operation and Higuma’s disturbance, used Luffy as a distraction, and ate the fruit himself before Benns could reclaim it. The theft diverted the World Government’s pursuit onto Su Hang and ruptured his relationship with Luffy. 2 3 5

Although he initially lacked control over his new body, Su Hang used it to protect Lia and Luffy from Higuma’s gunpowder trap, redirected naval shells away from Windmill Village, and helped expose the Government’s planned island purge. He nearly drowned while testing the fruit’s seawater weakness and was rescued by Luffy and Dadan. 6 10 12 13

After making a mutual restraint pact with Shanks, Su Hang escaped Windmill Village by faking his death and hiding aboard a grain ship. He became the Morning Bell Caravan’s escort, repelled the Grayfin Pirates, and later exposed Colonel Hawk’s trafficking operation at Graystone Port. Rather than keep Hawk’s stolen wealth, Su Hang made the vault’s contents public and directed the funds toward victims, harbor repairs, and resettlement. 16 19 21 25 28

Su Hang established the Dawnbringer Merchant Guild around public rules, merchant oversight, civilian evacuation priorities, and Qi Hai’s authority to restrain him. The group delivered grain and medicine, opposed Arlong’s protection racket at Cocoyasi Village, and began pursuing a Sky Island route connected to the Rumble-Rumble Fruit. 29 35 40 50

Appearance

Su Hang is an eighteen-year-old young man with black hair and a visible scar running through his right eyebrow. 1 39

• His rubber physiology allows his limbs and torso to stretch, compress, and rebound unnaturally. 5 10
• He frequently carries injuries from combat, including a damaged right shoulder, burn scars, and Seastone cuts. 20 25 43
• His body can visibly deform under gunfire, explosions, and blunt impacts without suffering ordinary penetrating damage. 5 6 25

Personality

Su Hang is pragmatic, calculating, and survival-driven. He treats information as a weapon, plans around enemy incentives, and is willing to manipulate allies when he believes it is necessary; he openly admits using Luffy to distract Benns during the Nika interception. 3 5

Despite this ruthlessness, he draws a firm line around civilian lives. He repeatedly risks himself to shield children, stop bombardments, rescue imprisoned laborers, protect medical shipments, and prevent villages from becoming collateral damage. His stated principle is that living people are not equipment and villagers are not numbers to be sacrificed. 6 10 16 25 42

He accepts accountability when his judgment fails. After losing control of the Nika Core and attacking his own crew, Su Hang accepts restrictions, grants Qi Hai authority to stop him, and requires records for any use of destructive power. 43 44 45

Abilities & Skills

Myriad Worlds Fusion System

Su Hang’s system identifies major opportunities and converts successfully intercepted, causality-altering gains into fusion modules. 1

• Fortune Perception — detects high-weight opportunities but initially provides only vague directions rather than exact targets. 1
• Opportunity Interception Determination — requires Su Hang to personally alter critical causality; simply stealing or hiding an object is insufficient. 3
• Perfect Fusion — removes most power-rejection reactions but does not erase the inherent costs of the fused power. 1
• Law Modularization — listed among the system’s functions, though its practical operation has not yet been explained. 1
• Altering a high-weight destiny triggers stronger “world correction,” attracting escalating threats. 1 20

Nika Core and Rubber Physiology

The Nika Fruit grants Su Hang a rubber body, allowing him to stretch, absorb impacts, and store force for sudden rebounds. 5 10

• Bullets deform his body rather than piercing it, and can be expelled or ricocheted back. 5
• He can stretch limbs across long distances to grab terrain, opponents, rigging, cannon mechanisms, and anchors. 6 24 27
• He uses recoil to launch himself, redirect artillery shells, ram ships, and deliver concentrated strikes. 10 30 35
• His rubber body cushions explosive shockwaves and blunt trauma, though heat, muscular strain, and internal injury still affect him. 6 25
• His body initially moved unpredictably; he frequently tangled his own limbs or lost balance while learning to fight. 6 7 9

Tactical Combat

Su Hang favors terrain, timing, ship rigging, and enemy overcommitment over straightforward exchanges. 10 21 35

• Redirects cannon fire by using cliff walls, cables, and his own stretched body as a launching mechanism. 10
• Turned the Grayfin Pirates’ grappling hooks and a predicted crosswind into a counterattack that sank two ships. 21
• Rescued Nojiko without entering the sea by using an anchor-chain rebound, Nami’s distraction, and a temporary sail platform. 35
• Uses deception and public evidence to deny opponents control of the narrative, notably against Colonel Hawk and the blockade at Graystone Port. 25 30

Leadership and Oversight

Su Hang organizes escorts as a public-service trade route rather than a conventional pirate fleet. 28 29 40

• Prioritizes civilian vessels, evacuation procedures, compensation for damaged cargo, and transparent rules of engagement. 29 40
• Refuses to distribute spoils among escort crews before victims and damaged ships are compensated. 29
• Gives Qi Hai authority to overrule him and use Seastone restraints if necessary. 29 40 45
• Requires destructive abilities and system fusion to be logged by duration, affected area, backlash, and ship damage. 40

Weaknesses and Limits

Perfect Fusion did not remove the Nika Fruit’s fundamental weaknesses. 1 12

• Seawater — prolonged or deep exposure drains his strength, suppresses his abilities, and can render him unconscious. 12 13 48
• Seastone — suppresses the Nika Core immediately on contact; Seastone fragments can leave lingering effects even after removal. 24 26 43
• Physical stamina — repeated stretching, recoil, and heavy impacts strain his muscles and joints. 10 20
• Haki — Su Hang knows that Haki can strike a Devil Fruit user’s true body, but he has not demonstrated Armament Haki himself. 7 35
• Unstable fusion — forcing the Nika Core beyond his mental limits causes emotional amplification, autonomous attacks, and loss of judgment. 43 44

Equipment / Weapons / Items

• Short sword — carried during his escape from Windmill Village and later used in combat. 17 24
• Dagger — used during the White Tower operation to disarm guards and breach locks. 49 50
• Seastone handcuffs — entrusted to Qi Hai as a restraint and symbol of the guild’s oversight authority. 29 40 45
• Dawnbringer — Su Hang’s ship and the operational center of the Dawnbringer Merchant Guild. 34 40 43
• Ability-testing records — documents his stretching distance, rebound interval, joint stress limits, and known weaknesses. 45

Relationships

• Monkey D. Luffy — Su Hang stole the Nika Fruit that was meant for Luffy, creating a rivalry rooted in betrayal. Luffy later saves Su Hang from drowning, and the two continue exchanging challenges while respecting each other’s resolve. 5 13 17 45
• Shanks — initially the fruit’s temporary holder and Su Hang’s most dangerous potential opponent. They make a pact: Shanks will kill Su Hang if he uses Nika to enslave innocents, while Su Hang will oppose Shanks if he abandons villages to Government slaughter. 11 16
• Qi Hai — former Marine major who becomes Su Hang’s ally, crew member, and designated check on his authority. Qi Hai helps establish the guild’s rules and is authorized to restrain Su Hang during dangerous situations. 25 28 40 44
• Mia Compass — navigator and tactical partner. Her wind forecasts, signals, and Weather Ball distractions repeatedly enable Su Hang’s plans. 21 35 49
• Lorne — Morning Bell Caravan captain and merchant partner. Lorne initially doubts Su Hang but later supports the escort route and Dawnbringer Merchant Guild. 19 21 28 30
• Makino — Windmill Village tavern owner who feeds, supplies, and worries about Su Hang during the Government pursuit. 1 14 17
• Curly Dadan — rescues Su Hang from the sea with Luffy and remains bluntly critical of his reckless preparation. 13 15
• Nami — collaborates with Su Hang during the conflict with Arlong’s men, using a Weather Ball to help rescue Nojiko. 34 35 37
• Thorne — Marine officer who pursues Su Hang while also investigating Hawk’s crimes. Their relationship remains adversarial but marked by procedural cooperation. 26 27 30
• Grave — architect of the White Reef traps and White Tower operation. Su Hang chooses to rescue Grave’s researchers rather than abandon them to pursue him. 49 50
