King Dice is the right-hand man of the Devil and the secondary antagonist of Cuphead, making his very first appearance in the game in the opening cutscene. He can be found within every Dice House, where he acts as a gatekeeper, blocking passage between isles until a required list of soul contracts are turned into him by either Cuphead or Mugman.

King Dice is roughly six feet tall, having the body of a human man, but with his head being modeled after a floating dice.
