The Ope Ope no Mi (Op-Op Fruit) is an unreleased Paramecia-type Devil Fruit that allows its eater to produce a spherical space or "room" in which the eater has complete control over the placement and orientation of all objects (and people) inside, making them a Free Modification Human.

Ope Ope no Mi is not in the game in its current state, but from official footage appears to be almost complete. However, the developer Benere said it won't come for a while.[1]

The last piece of official public footage released was on February 2020.

  • It has been mentioned by some YouTube testers that Ope Ope's 'Room' max size scales with the user's Devil Fruit stat.
  • It is the only fruit in-game able to generate pickable items.
