Spiritomb resembles a swirling, purple vortex with green, varying in size orbs of light circling the face. It has a green mouth with a crooked expression and two green eyes shaped like half-crescents. One of the eyes has a spiral-shaped pupil. Spiritomb is attached to a light-brown/gray stone, the Odd Keystone, in which it was trapped after doing bad deeds 500 years ago. It is apparently composed of 108 separate, yet bound-together, malevolent spirits.
