Hadras is a cursed crew member of the Flying Dutchman, the supernatural ship owned by Davy Jones. He is half man and half hermit crab, with a shell around his head. He became a member of the crew prior to Dead Man's Chest. In Dead Man's Chest, he is sent with the crew to reclaim the Dead Man's Chest from Jack Sparrow and his crew. He steals the Dead Man's Chest and tries to escape with it. During the ensuing battle, Jack throws a coconut at him and knocks his head off. His shell head sprouts legs and follows his body back to the Dutchman. In At World's End, he is present during the battle of Calyso's Maelstrom. The Dead Man's Chest falls on his head, flattening it, and he topples off the side of the Dutchman.
