Surgical fruit

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?).[4] It was eaten by Trafalgar D. Water Law, who was force-fed it by Donquixote Rosinante.

The fruit's power was first seen during the Sabaody Archipelago Arc,[2] but the fruit itself was not named or explained in any way until the Punk Hazard Arc.[4]

This fruit is called the "Ultimate Devil Fruit" (究極の悪魔の実 Kyūkyoku no Akuma no Mi?), because of its unique power to grant another person eternal youth in exchange for the current user's life.[5] The Marines were willing to pay as much as 5,000,000,000 to buy the fruit from a pirate named Diez Barrels.[6] The fruit is also renowned and coveted for allowing the user to perform miraculous surgeries as well as to cure diseases without any known cures and even circumvent physical disabilities.
