This is the Ishi Ishi no Mi. The Stone-Stone Fruit. Pica ate it—and became the mountain.

• Paramecia-type Devil Fruit
• Ability: Allows the user to merge with and manipulate stone, reshaping terrain and controlling massive structures
• Used by: Pica, top executive of the Donquixote Pirates and living fortress with a squeaky voice

This fruit doesn’t just move rocks—it becomes them. Pica fuses with entire plateaus, builds stone giants, and turns cities into battlegrounds sculpted by his will. He’s not just hard to hit—he’s hard to find.

The model captures the sheer scale and intimidation of a fruit that turns stone into strategy—and the user into a geological nightmare.
