Hobi Hobi no Mi

This Paramecia lets its user turn living beings into toys and erase every memory others hold of them, while a side effect grants the eater eternal youth. It belongs to Sugar of the Donquixote Pirates. Shaped like a yo-yo, the wheel-like fruit has a spiraling pale-yellow core on each side, a red swirly shell, and a thick winding-key stem. Its name comes from hobi, the Japanese rendering of hobby, a word also used there for collecting toys.

A touch from the user transforms a person or animal into a toy, and a contract sealed immediately afterward forces the victim to obey every command. Toys lose their physical strength, shrink, often down well below human size even for giants, and find their Devil Fruit powers and weapons gone, though any combat skill they had is retained. Being inorganic, they deteriorate under strain and are vulnerable to powers like the Pamu Pamu no Mi. The chilling core of the ability is instant, total memory erasure: the moment someone becomes a toy, everyone forgets they ever existed, even witnesses, leaving no one to mount a rescue. The user can also choose the toy's shape and combine several victims into one larger doll. Knocking the user out or killing them cancels every transformation and restores all memories, so Sugar required constant protection. Loopholes let some toys defy their contracts, physical evidence like engravings survives the memory wipe, and the user must touch a target with a bare hand and deliberately will the change.

Sugar is the only user, and her power was central to Doflamingo's underworld operation, turning the citizens of Dressrosa and beaten Corrida Colosseum fighters into a steady supply of forgotten slaves while Trebol guarded her. The transformation is known to its victims as the Hobi Hobi Curse. Having eaten the fruit at age ten, she stopped aging for twelve years and passed as a harmless little girl. Named techniques include Keiyaku, the binding contract; Little Black Bears, a rapid touch that turns many foes into teddy bears at once; and Atamawari Ningyo, giant nutcracker dolls each built from eight people, with crushing jaws and the durability to reattach a severed head and keep fighting.
