One Piece Wiki

The Jiki Jiki no Mi[2] is a Paramecia-type Devil Fruit which allows the user to create magnetic forces and use them to control metal. It was eaten by Eustass Kid.[1]


  • Jiki (磁気?) is Japanese for "magnetism".


The Jiki Jiki no Mi takes the appearance of a clustered set of silver spheres with a yellow vine wrapped around them up to the stem, resembling a cluster of grapes. Each sphere has a small jagged offshoot, akin to a bolt of lightning protruding from it, as well as the typical swirl pattern seen on all Devil Fruits. Interestingly, the stem of the fruit is also equally as jagged, resembling a bolt of lightning, save for the end portion that curves into a spiral shape.[3]

Strengths and Weaknesses


Kid manipulating metal with magnetism.

The Jiki Jiki no Mi enables the user to generate magnetic fields that can either attract or repel metallic objects to and from their body as they please. This makes them particularly effective against the majority of weapons in the world: namely swords, guns, and cannons. By using repulsion, the user can deflect metal projectiles back to where they came from, turning them against the aggressor.[1] Using attraction, the user can strip opponents of their weapons and bring them to their own body, rendering said opponents helpless.[4] The user can also use attraction to pull themselves to large metal objects like ships, allowing them to travel through the air in a manner resembling flight.[5] In general, the creatable magnetic forces are extremely strong and very difficult, if not impossible, to resist; by wrapping a metallic arm around Big Mom and repelling it, Kid was instantly able to send her flying up in the air, a noteworthy feat considering Big Mom's massive size and weight.[6]

The fruit gives the user a sufficient degree of control over their magnetism to accumulate a large amount of metallic objects around their body and form them into specific shapes; the user can then move these masses around very fluidly, either by being directly connected to them or not. This has been seen repeatedly with Kid, who has accumulated metal objects on his body to form normally-functioning apparatuses like mechanical arms,[4] Gatling guns,[6] railguns, and even exoskeletal fighting machines.[7] Provided there is enough metal around, the users' creations can become very large in size quite easily and are, thus, capable of inflicting tremendous damage with simple crushing attacks.[8] Even with massive apparatuses attached to his body, Kid has never shown himself to be physically burdened by them. Objects assembled with magnetism can maintain their structural integrity even after being separated from the user's body.[9] Since the majority of these creations consist of random pieces of scrap metal held together purely by magnetism, attacks that damage these creations typically do little against the user, as they can just reform them with ease.[10]


As with other Devil Fruits, this fruit's ability is capable of being awakened. Once achieved, the user is capable of turning other objects, including living organisms, into magnets by assigning them with a specific polarity.[11] This awakening has possible applications that do not rely on the user requiring metal from his surroundings, diminishing that specific weakness to an extent.[12]


Kid dragging around a hoard of scrap metal for combat use.

This fruit's combat applications are very dependent of a sufficient amount of metal to be present in the user's surroundings, especially in order to create bigger, more complex contraptions. As such, the user may be required to first amass metal objects in large quantities before facing a tough enemy. During the raid on Onigashima, Kid was forced to run around the island for quite some time in order to hoard enough metal pieces to utilize in the impending confrontation with Kaidou and Big Mom. However, no matter how much metal the user stockpiles, it seemingly will continue to stick to the user's body and get dragged around wherever they go, forming a gigantic, moving wall of scrap that may even engulf people in its way.[13][14]

Another known weakness is that the magnetic forces holding larger metal constructs in place will weaken if the user himself receives significant damage.[15] For some reason, the fruit appears to have no effect on Pacifista despite their metallic composition (although it is worth noting that Kid was unaware of their nature as cyborgs at the time).[16] Otherwise, the user is affected by the standard Devil Fruit weaknesses.


Kid makes heavy use of both attraction and repulsion during combat. Through repulsion, Kid repels metallic objects away from himself as a counter-offensive measure, such as reflecting a cannonball back towards its shooter. Through attraction, Kid draws in various metallic objects (often disarming his enemies in the process) and then assembles a mechanical contraption made from said objects. By far, Kid's most common application of the latter ability is to form gigantic, metallic arms connected to his actual ones, employing those in close-ranged combat.

Kid can shape random metallic objects into fully functional limbs, tools and weapons in a short amount of time and with no apparent difficulty, demonstrating a high degree of mastery over his Devil Fruit ability coupled with excellent engineering skills. Besides large mechanical arms, Kid can make enormous golems out of scrap metal that he can simultaneously ride and control with magnetism, form fully functional firearms for ranged combat or even build simple objects like boxes for imprisoning targets, giving the fruit support utility as well.

Despite being dismembered by one of the Four Emperors, Kid easily adapted to his lost arm by successfully replacing it with a makeshift prosthetic arm created from his magnetic powers. In the event that Kid loses his prosthetic arm for whatever reason, he can just make another one on the spot with any metal items he manages to attract to himself.[17] Kid can also repel his mechanical arm from his body as a surprise technique to catch enemies off guard.[18]

Kid has mastered the fruit's ability to the point of awakening it, allowing him to manifest magnetic properties on targets through direct touch. Should a target be affected by this with a significant amount of metal surrounding them, they will be quickly crushed by the metal, with the forces of attraction being strong enough to even rip large, established structures toward them. Kid can also cleverly stick a person to a piece of the environment by assigning both of those with inverse polarities, rendering the former immobilized and thus vulnerable for subsequent attacks.[12] However, he is not used to his awakening yet and only uses it as a last resort due to the large amount of stamina it draws from him.[11]


  • Repel (反発リペル Riperu?, literally meaning "Repulsion"): Kid holds out his open-palmed hand in front of a metal object approaching him and repels it back in the direction it came from. Kid can also repel a person if he covers a portion of their body in metal (which can include even his own prosthetic arm) beforehand, letting the repelled metal covering push them away.[18] This attack was first seen at the Human Auction House where he repelled a Marine cannonball at high speed back toward the shooters.[1]

Punk Gibson.

  • Punk Gibson (磁気パンクギブソン Panku Gibuson?, literally meaning "Magnetic String"): Kid attracts metal pieces to one of his arms in order to form a massive, makeshift arm. He then slams it into his opponent, crushing them. Kid first demonstrated his attack on Sabaody Archipelago, when fighting the Marines outside the Human Auctioning House. It only received a name during the Wano Country Arc after he used it on Scratchmen Apoo at Onigashima.[19] Its name may be inspired by Gibson, a US manufacturer of guitars.

Punk Rotten.

  • Punk Rotten (磁気パンク魔人ロットン Panku Rotton?, literally meaning "Magnetic Demon"): Kid attracts a large quantity of metal from his surroundings and shapes it in the form of a gigantic skull-faced demon-like golem made of scrap. The demon is composed of a floating torso with two disembodied arms, with Kid seating himself on its back and controlling it from there.[20] Because it is made of random pieces of scrap metal, the demon can break down and be rebuilt as many times as Kid wants with his magnetic abilities, without major consequences to him.[10] This attack was first used to destroy a ship of the Beasts Pirates in conjunction with Monkey D. Luffy and Trafalgar D. Water Law, although it was kept unseen at the time.[21] Punk Rotten only truly debuted during the rooftop fight against Kaidou and Big Mom. The name of the technique may be inspired by Johnny Rotten, lead singer of the late-1970s British punk rock band Sex Pistols.
    • Punk Vise (磁気パンク万力ヴァイス Panku Vaisu?, literally meaning "Magnetic Vise"): After forming Punk Rotten, Kid makes the golem crush a target with both hands. This attack was first seen in use against Kaidou.[20] Since both "Vise" and "Vice" are rendered the same in katakana (ヴァイス), the technique's name may be inspired by the British punk rock band Vice Squad.
    • Slam Gibson (破壊弦スラムギブソン Suramu Gibuson?, literally meaning "Destruction String"): Kid uses his golem's arms to grab his opponent and slam them to the ground. It was first used against Kaidou.[22] As deducted from the name, this move may be a reference to guitar smashing, a common practice for rock musicians on-stage.
  • Punk Pistols (磁気パンクピストルズ Panku Pisutoruzu?, literally meaning "Magnetic Pistols"): Kid forms a giant harpoon gun out of metal pieces around his right arm, from which he is capable of rapidly firing metal spears at a target akin to a Gatling gun. It was first used against Big Mom, but the move failed since the spears could not pierce through her incredibly tough skin.[23] Its name may be inspired by the British punk rock band Sex Pistols.

Punk Corna Dio.

  • Punk Corna Dio (磁気パンク大魔牛コルナ・ディオ Panku Koruna Dio?, literally meaning "Magnetic Great Demon Bull"): Kid attracts a large quantity of metal pieces from his surroundings and shapes it in the form of a gigantic, metallic bull-like contraption that is even larger than a powered-up, giant-sized Big Mom. Then, while riding on its back, Kid makes the bull charge towards his enemy so it can headbutt them down. It was first used against Big Mom,[24] being strong enough to cause damage to her bones.[25] Corna is Italian for "horns" and also a handsign in heavy metal, popularized by Ronnie James Dio.

Damned Punk.

  • Damned Punk (電磁砲ダムドパンク Damudo Panku?, literally meaning "Electromagnetic Cannon"): Kid utilizes a large amount of metal to construct an enormous railgun, which he then uses to fire an electromagnetic projectile at the target. It was first used against Big Mom, causing significant damage to her and sent her off Onigashima.[26] This technique's name might be inspired by the British punk rock band The Damned.

Awakened Techniques

  • Assign (付与アサイン Asain?, literally meaning "Assignment"): Kid touches a foreign object or person and thereby turns them highly magnetic. Specifically, Kid assigns a magnetic polarity to a given target, signified by him saying either S (Sエス Esu?) for South or N (Nエヌ Enu?) for North, and the magnetized object/subject displaying the respective letter somewhere on its/their surface.[12] Targets with different assigned poles will then be drawn into one another with immense force until sticking together. First used against Big Mom, the technique caused Napoleon to be stuck to her head.[27] Later on, Kid showed the complete application of the technique by sticking Big Mom to one of Onigashima's Live Floor structures.[12]
    • Punk Clash (磁気パンク激突クラッシュ Panku Kurasshu?, literally meaning "Magnetic Clash"): After magnetizing someone else with Assign, Kid greatly increases their level of attraction, causing them to draw countless pieces of metal from large distances towards them. When used against Big Mom, she was quickly buried underneath a mountain of steel beams that were part of the framework of Kaido's Castle.[27] The name of this technique may be inspired by the British punk rock band The Clash.

Video Game-Only Techniques

  • Genocide Raid (ジェノサイド・レイド Jenosaido Reido?): A technique in the video game One Piece: Gigant Battle! 2 New World, Kid creates a vortex of metal pieces around the enemies that seem to both shock and pummel them at the same time, knocking them off their feet.

  • When using his Devil Fruit ability, purple electrical sparks emit from Kid's hands, so his ability may resemble an electromagnet.[28]
  • In the manga, among the metallic items Kid summoned to attack Apoo on Onigashima, the Pokémon Meltan can be seen.[29] Another one appears at his right shoulder when the Beasts Pirates recognize him.[30] Oda has expressed his love for the mobile game Pokémon GO, in which Meltan debuted, in a Weekly Shonen Jump authors comments page.[31]
  • In the anime, from the start of the Raid on Onigashima and onwards, the metal objects attracted by Kid now appear to be mostly computer-generated, giving them a distinct tridimensional appearance.
  • Shueisha's VJump Play worked with cardboard crafting influencer Tsuruku "Crafty Transformer" to make a cardboard replica of Kid's prosthetic left arm and a downloadable template of the craft.[33]
