Mimzy is a short and plump demon with pale-lilac skin and platinum-blonde hair, which has been kept into a 1920s-style bob cut. Her eyes have cerise-colored pupils, black sclera, and thick lashes colored in a very dark shade of magenta. Mimzy is a bratty, materialistic diva, who appears to have many self-centered traits that the people around her react strongly to. She appears to conflict with other strong personalities. Mimzy is very thirsty for attention.
