Demon Monster is a monster made out of demons’ corpse. Its right hand is long enough to be used as a whip and its left hand is used to thrust its enemies like a spear. Its mouth is at the center of the chest and eats the meats with it. But it doesn't have any eyes or nose. It's just a living weapon made only for assault.
It has very low intenlligence, but it is a powerful demon. It's big and ugly, and very aggressive. It even eats the demon workers nearby. It must be the worst enemy in the cave.
