جيكي جيكي نو مي

Rooted in magnetism, this Paramecia power grants its wielder the ability to conjure magnetic forces and steer metal with them. The name springs from jiki, the word for magnetism in Japanese, and overseas releases dub it the Magnet-Magnet Fruit. John, a pirate of the Rocks era, was the first to eat it; after he died it went back into circulation and eventually reached Eustass Kid. The fruit itself looks like a bunch of silver spheres wrapped in a yellow vine, each sphere carrying a tiny lightning-shaped spur, with a jagged bolt-like stem that brings to mind the Goro Goro no Mi.

Fields the user generates can either haul metal toward them or drive it away. Repulsion swats aside swords, bullets, and cannon shots, hurling projectiles back at whoever fired them, while attraction rips weapons from enemies and can drag the wielder skyward toward big metal masses such as ships. So overwhelming are these forces that Kid launched the giant Big Mom into the air by looping a metal arm around her and repelling it. Given enough nearby metal, the wielder heaps scrap onto their body and sculpts it into functioning machinery, whether mechanical arms, Gatling guns, railguns, or exoskeletal war rigs, then glides those masses about at will. Because the constructs are merely scrap bound by magnetism, harming them accomplishes little, since they knit back together. After awakening, the power can stamp a magnetic polarity onto any object or even a living body, converting targets into magnets without depending on surrounding metal. That dependence is the main flaw: against a formidable foe the wielder may first need to gather a stockpile of metal, which then clings and trails along everywhere they travel. Serious injury to the user saps the magnetism keeping their bigger constructs intact, and for reasons unknown the fruit did nothing against the metal-bodied Pacifista. The standard Devil Fruit penalties apply as well.

John wielded the fruit mostly to pile up riches, dragging chests and valuables to himself with the Big Eater move during the God Valley Incident, and outfitting himself with a mechanical gauntlet. Eustass Kid is by far the more combat-driven owner. Mixing attraction and repulsion at will, he bats away cannonballs with Repel and builds enormous scrap limbs, his hallmark being Punk Gibson, a giant makeshift arm that crushes foes. He constructs larger devices too: the demon-shaped golem Punk Rotten with its Punk Vise and Slam Gibson finishers, the harpoon-spitting Punk Pistols, the bull-formed Punk Corna Dio, and the railgun Damned Punk that helped hurl Big Mom off Onigashima. Having lost his left arm, Kid built a magnetic prosthetic he can rebuild whenever he likes. His awakened move Assign magnetizes a target, while Punk Clash entombs foes beneath a heap of metal. Almost every technique of his tips its hat to punk rock culture.
