One Piece vs One Punch Man: Every One Piece Cyborg Genos Would Dismantle in a Deathmatch
Two anime juggernauts, one burning question: whose cyborgs reign supreme? As One Piece icons Franky and Kuma go head-to-head on paper with One Punch Man’s chrome bruisers, we size up the upgrades, tactics, and knockout power.
One Piece and One Punch Man could not be more different, but they do share one fun overlap: cyborg brawlers who turn every fight into a fireworks show. So, naturally, the question pops up: how many One Piece cyborgs could Genos realistically put in the dirt in a straight deathmatch? Short answer: a lot. Longer answer: here’s the breakdown, pulled from what both series have actually shown on screen/page.
Ground rules (so this makes sense)
I’m comparing what we’ve seen these characters do in their own stories: no headcanon, no mystery power-ups, just demonstrated abilities, durability, and how their gimmicks stack up against Genos’s speed, flight, targeting systems, and ridiculous energy output. The matchups below go from the easiest wins to the toughest fights.
Who Genos beats, and why
-
Hit Man Gotti (Fire Tank Pirates)
Gotti’s a heavy hitter for Capone Bege’s crew, introduced in Whole Cake Island, and he’s got a three-barreled machine gun where his right forearm used to be. Effective enforcer, sure. Cyborg terror? Not really.
Why Genos wins: speed and reflexes. He can intercept or dodge the gunfire, melt the weaponized arm before it spins up, and tank anything Gotti throws back.
Weakness Genos exploits: slow, lightly protected chassis.
-
Ahiru (Revolutionary Army East Army)
Deputy commander under Belo Betty, mostly seen supporting the fight with a mechanical prosthetic that shoots projectiles. No Devil Fruit, no notable brute force feats so far.
Why Genos wins: better range, mobility, and durability. He stays out of her limited firing lanes and just blasts from a safe distance.
Weakness Genos exploits: low durability and short effective range.
-
Sea Beast Weapons (Marines/Vegapunk)
Vegapunk’s cybernetic monsters fuse real Sea Beasts with heavy weaponry. They’re huge, brutally strong, and can fire serious energy shots in or out of the water.
Why Genos wins: superior energy control and flight. He can juke their telegraphed barrages, counter with concentrated beams, and stay airborne where their aquatic bias hurts them.
Weakness Genos exploits: predictable aim and exposed key modules.
-
Pacifistas (Kuma models)
Mass-produced cyborgs built by Vegapunk, patterned after Bartholomew Kuma. Metal bodies, lasers from the mouth and hands, and a history of wrecking pirates. They’re tough, but they follow orders and move like tanks compared to top-tier fighters.
Why Genos wins: he outpaces their targeting, threads through the laser fire, and hammers weak points with higher-output blasts.
Weakness Genos exploits: sluggish movement and predictable patterns.
-
Vinsmoke Ichiji (Germa 66)
Germa’s eldest son rocks a raid suit that amps speed and durability and fires concentrated shock beams (think his Sparking Red-style attacks). Strong, but not in the same tier as One Piece’s top Devil Fruit users.
Why Genos wins: he can absorb or override those shock outputs and return stronger fire. Genos’s targeting and reactive systems are built to read and counter energy offenses.
Weakness Genos exploits: heat buildup and a narrow defensive envelope once the suit is pressured.
-
Vinsmoke Reiju (Germa 66)
Germa’s eldest child leans on poison and chemical tricks with agile movement and defensive tech. She’s more support/utility than front-line bruiser.
Why Genos wins: toxins don’t do much to a mostly mechanical body. He overwhelms with raw firepower before any setup matters.
Weakness Genos exploits: poison is a non-factor against a cyborg; she can’t match sustained damage output.
-
S-Snake (Seraphim, Hancock model)
A next-gen Pacifista built with Boa Hancock’s lineage factor and Green Blood, letting her replicate Mero Mero abilities like charm and petrification on top of the Seraphim’s absurd durability.
Why Genos wins: charm/petrification doesn’t meaningfully work on a machine. Once that ace is gone, precision beams to the Green Blood systems can shut her down.
Weakness Genos exploits: her signature charm is useless on machines; internal systems can be targeted.
-
S-Shark (Seraphim, Jinbe model)
Combines Senor Pink’s Swim-Swim Fruit with fish-man karate in a Seraphim frame. He hits insanely hard and thrives around water.
Why Genos wins: keep it aerial and at range. Genos’s flight nullifies the aquatic edge, and repeated concentrated blasts can stress the armor and fry internals.
Weakness Genos exploits: slower and less dominant on land, with vulnerable circuitry once the plating is compromised.
-
S-Hawk (Seraphim, Mihawk model)
A Mihawk-inspired Seraphim with close-range nightmare swordsmanship and slicing power boosted by Mr. 1’s Dice-Dice Fruit. He’s fast, precise, and built like a black box.
Why Genos wins: do not let him close the gap. Genos has to play pure range, dodge the rushdowns, and hammer away until a vulnerability shows. Not easy, but doable with superior fire volume.
Weakness Genos exploits: distance. He’s far less scary if he can’t get into cutting range.
-
Franky (Straw Hat Pirates)
Straw Hat shipwright and self-made tank: cannon arms, lasers, reinforced plating, and the Franky Shogun that can even go full mech-tank mode. Durable, crafty, and hits like a truck.
Why Genos wins: higher energy output, better burst speed, cleaner precision. He can angle attacks to disable weapons pods and then crack the armor with heavier beams.
Weakness Genos exploits: big frame with stress points around joints and weapon mounts.
-
Queen (Beast Pirates All-Star)
A top Beast Pirates commander with serious physical power, gnarly mechanical upgrades, and those notorious viral weapons. He’s durable and dirty in a fight.
Why Genos wins: range and tempo. Genos pours on fast, focused explosions that punch through plating and cook the internals before Queen can set up gimmicks.
Weakness Genos exploits: comparatively slow and the bio-weapons don’t matter against a cyborg.
-
Bartholomew Kuma (former Warlord)
Vegapunk-modified juggernaut with the Paw-Paw Fruit, able to repel anything he touches, including people, damage, and even concepts like pain. He can also effectively teleport and has showcased wild durability, especially highlighted during Egghead.
Why this is hard: Genos cannot afford to get tagged by a paw pad deflection or he’s getting yeeted across the map, reset after reset. The only path is relentless, multi-angle pressure to force openings between deflections and thread shots into weak spots.
Weakness Genos exploits: small timing windows between paw counters. If he finds one, he can finally break through.
That’s my read based on what we’ve actually seen. Got a cyborg I underrated or a matchup you think flips? Drop it in the comments and make your case.
One Piece and One Punch Man are both streaming on Crunchyroll.
