Kyara Kyara no Mi

This fruit shows up in the Fischer's x One Piece crossover and falls among the non-canon Paramecia powers. It hands consciousness to a non-living soul and opens the way for that soul to merge with other beings. The name comes from the Japanese pronunciation of the English word character. Lip Shark, its eater, leans on the merging trait to raise the capabilities of anyone he bonds with. In manga-style art the fruit itself looks like a coil of purple droppings, marked with the usual Devil Fruit swirls yet missing any stem.

Fusion is the core strength, granting large jumps in strength and speed to the joined party, though whether any rule governs who may be merged stays unclear. Once past the timeskip, Lip Shark managed to fuse even with the bow of the ship known as the Maying Gorry. No clear drawbacks are known apart from the ordinary Devil Fruit vulnerabilities. He claims his power flows from the millions of fans that Fischer's commands, but it is uncertain whether that reliance counts as a weakness of himself or of the fruit. His Transform move merges him into another person for a hefty physical boost while also manifesting an ability shaped by that person's character, and it first went by the name Union. Two-Headed Mascot Mordo instead reshapes him into a young boy so he can move through the world as a human would.

Lip Shark is the fruit's holder, deploying it to strengthen members of the Fischer's Pirates so they can beat foes well above their level. Whether the fruit genuinely exists within the wider One Piece world remains ambiguous, since it may reside only inside the pseudo-world conjured by Mr. Kuromaku.
