The Ope Ope no Mi is a Paramecia-type Devil Fruit that allows its user to create a spherical space or "room", in which the user has complete control over the placement and orientation of the objects inside, making the user a Free Modification Human (改造自在人間 Kaizō Jizai Ningen?). It was eaten by Trafalgar D. Water Law. The fruit's power was first seen during the Sabaody Archipelago Arc, but the fruit itself was not named or explained in any way until the Punk Hazard Arc.
