The Ope Ope no Mi is a fictional Devil Fruit from the anime and manga series One Piece. It grants its user the ability to create a spherical area called an "operating room," where they can manipulate anything within that space. This includes the power to perform surgeries, move objects, and even alter the physical state of living beings. The fruit is primarily used by the character Trafalgar D. Water Law, who is known for his medical skills and strategic combat abilities. The Ope Ope no Mi is classified as a Paramecia-type fruit, which means it grants the user special abilities that are not inherently superhuman.
