The Joker Monster is a tall humanoid Trollge with a pitch black body. The only features noticeable are on his face which shows a white glowing toothy grin and white "happy-looking" eyes (that resembles that of an Alternate from the Mandela Catalogue). The monster’s voice is deep but easy to make out. It will tell jokes until they (user) die of an heart attack from laughing too much. Their arms are long and almost touches the ground.
