Kinzoku Kinzoku no Mi (Logia)
Power of metal and is resistant to magnets.
Form 1: Solid Form
Ikenga's body becomes harder than steel, and is even more powerful when enhanced with haki and Tekkai. Since he is a Tekkai master, he can move with it still activated. He can morph his body and body parts into any metal shape of any size, be it a tiny pin, or a war hammer the size of a ship.
Form 2: Liquid Form
Ikenga's body becomes liquid, making attacks slip through it, and allow speedy travel as liquid metal. In this form he mostly uses it for traveling, but in combat, he can mummify an enemy by covering them with metal and crushing them. In liquid form, he can also whip himself around as a highly-pressured liquid.
Form 3: Particle Form
Ikenga turns into metal dust, and is his most powerful form. He can shoot the dust as such high speeds that each speckle is like a miniature bullet. He can mimic sandstorms and attack you with a flurry of particles which can decimate giants easily, when reinforced with Haki. He has been known to demolish large towns in one swift strike in this form.
