.

Jack T. Rikker is the cook of the Ghost Pirates. Before joining, Rikker was a serial killer that was known for torturing his victims to death, and dismembering their corpses, before cooking their guts and serving them to noble families.

Despite this, Rikker is actually a very experienced chef with vast culinary knowledge.

Devil Fruit
Rikker ate a devil fruit that enables him to multiply the weight of things he comes in contact with. He can transfer this power to his trademark hammer, making everything it touches much heavier.

He uses this power to torture his victims, by making their own body parts so heavy they slowly and painfully tore off from their bodies.
