Much like his lackey, King Dice, his normally small, black pupils seem to gain large, red irises when behaving in a particularly sinister manner. He also has a drooping, round nose, tall, smooth horns, and ears that are pointed at their tips.
He has round, protruding cheeks, a furrowed brow, and heavily-lidded, yellow eyes. The Devil is almost always shown sporting an ear-to-ear, toothy grin. He is often illustrated carrying a pitchfork in his hand and/or tapping the big toe on one of his feet. While the color of his face matches that of his fur, the bare skin on his hands and feet are a much lighter grey at the end of each of his fingers and toes are short, pointed claws.
With the exception of his face, hands, and feet, the majority of the Devil's body is covered in short, black fur.
