The Demon (also well known as a Pinky Demon or just Pinky) is a relatively muscular, human sized monster found within the DOOM Universe. Demons are of a pinkish hue and have yellow eyes, one downward-curved horn on both sides of their head, a jutting spine, sharp, bloody teeth, humanoid hands, and elephant-like feet. They walk with a long swing in their arms and move rather quickly. The fact that one variant is known as a "bull demon" may indicate that the "pinkies" are, in fact, females though this is simple speculation. It could also indicate that pinkies could be immature or castrated (or some other form of removing sexual capability).
