Mismagius is a purple, ghost-like Pokémon that has the appearance of wearing a cloak. The three red spheres of Mismagius's "necklace" have a slightly elliptical shape to them, and its neck appears somewhat long and crooked. It has a round head and a large, elaborate, tufted feature atop it, the extremities of the tufts being a lighter color than most of the body. This feature resembles a witch's hat in shape. Mismagius has a thin, red mouth that resembles the letter "W." There are extensions on the sides of Mismagius's lower body, the foremost ones looking more ragged in appearance than the ones in the back, that give Mismagius the appearance of wearing some kind of cloak.
