Jiki Jiki no Mi

The Jiki Jiki no Mi is a Paramecia-type Devil Fruit which allows the user to manipulate magnetic forces. It was eaten by Eustass Kid.

Strengths and Weaknesses
The main strength of this fruit is that the user can manipulate metal through magnetic force, using it to attract or repel metal objects in relation to their person. The user's magnetism is symbolized by sparks generated by their body. Once active, the user becomes capable of levitating metal objects towards or away from themself.

The user can employ the metal to their whim, such as for offensive purposes like controlling cannonballs or forming a metal shell around themselves for either offensive or defensive purposes. Attacks using metal objects like bullets or cannonballs can simply be repelled. This makes the fruit very effective against people who rely on metal objects and weapons, such as the Marines.

The main weakness of the fruit seems to be its dependence from the surrounding environment, which must contain metal in order for the fruit's powers to be used. Other than that, the user is affected by the standard Devil Fruit weaknesses.

Usage
Kid manifests two different abilities, both depicting repulsion and attraction of metals within his vicinity to be used as weapons. The first allows him to repel metallic objects away from himself, such as reflecting a Marine cannonball back towards its shooter. The second ability allows him to draw metallic objects towards him and form them into objects, his most frequent use of this being to form a giant arm made of hundreds of metallic weapons and objects and connecting it to his right hand. When forming this metallic arm, he can use it to punch his opponents, or as a makeshift shield to block even a Pacifista's laser beams. It is unknown if the firearms connected to his metal arm can fire at his will or not.

In the anime and Unlimited Cruise game, Kid can also launch compressed bullets of scrap metal at his opponent at high speed.

Techniques

 * Repel: 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 prosthestic arm) beforehand, letting the repelled metal covering push them away. This attack was first seen at the Human Auction House where he repelled a Marine cannonball at high speed back toward the shooters.




 * Punk Rotten: 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. 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. 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. Punk Rotten only truly debuted during the rooftop fight against Kaido 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: After forming Punk Rotten, Kid makes the golem crush a target with both hands. This attack was first seen in use against Kaido. 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: Kid uses his golem's arms to grab his opponent and slam them to the ground. As deducted from the name, this move may be a reference to guitar smashing, a common practice for rock musicians on-stage. It was first used against Kaido.
 * Punk Gibson: Kid attracts metal pieces to his right arm to form a massive, makeshift arm. He then leaps into the air and slams his open metal palm into his opponent, crushing them. This attack was first seen used against Scratchmen Apoo on Onigashima. Its name may be inspired by Gibson, a US manufacturer of guitars.
 * Punk Pistols (ピストルズ): 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. Its name may be inspired by the British punk rock band Sex Pistols.

Video Game-Only Techniques

 * Genocide Raid (ジェノサイド・レイド): 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.

Trivia

 * When using his Devil Fruit ability, purple electrical sparks emit from Kid's hands, so his ability may resemble an electromagnet.
