Nui Nui no Mi

This Paramecia power grants the ability to bind things together with stitches and just as cleanly undo them, as though nothing had happened. Leo of the Tontatta ate it. Officially the fruit was never named within the manga itself, where Leo simply called his trick a Nui Nui power written in hiragana rather than the katakana reserved for Devil Fruit names. A One Piece magazine later confirmed both the name and its Paramecia classification. The fruit's body is segmented like an orange in mixed colors, held by stitch-like growths, with a stem shaped like a metallic needle threaded with a strand of green.

The user can fasten objects to any surface, which makes the power ideal for restraint, pinning a target to the floor, a wall, or another person. Reversing the work is just as effortless. The stitches neither wound the victim nor seem to actually pierce them, yet they held Nico Robin firmly, and Leo once lashed Marine warships together to stop them chasing the Straw Hats. That feat on solid steel shows the hardness of the material does not impede the sewing. Beyond restraint, the ability secures belongings during earthquakes and can reattach severed limbs, though ragged wound edges hurt its effectiveness and it does not actually heal the injury. One apparent requirement is a sewing needle, since Leo has never been shown using the power without one. His signature technique, Haute Couture: Patchwork, stitches an opponent's allies to them, then yanks the thread so every bound figure crashes into the target at once. Aside from that, only the standard Devil Fruit weaknesses apply.

Leo is the fruit's lone consumer, using it to immobilize foes, brace objects against tremors, and bind enemy vessels. He defeated Giolla by drawing her own comrades into her with Patchwork. The power draws comparison to Doflamingo's Ito Ito no Mi through their shared reliance on thread, and to the Choki Choki no Mi for ignoring a material's strength.
