Pirate: Roaming the Seas in the Name of the Death Doctor

Transmigrated into the world of One Piece as Trafalgar Law, wielding the power of the Ope Ope Fruit and a unique constitution. Years later, a new Emperor of the Sea rises. "You... want to taste the surgery that brings death?" (Timeline and character backgrounds differ slightly from the anime—think of it as a parallel world of One Piece.) (Synopsis can't do it justice—please read the actual story, my lords!!!)
