Skell has shoulder-length black hair with black horns, the left one having two white stripes. Unlike the others, Skell has a torso that made it look like his shirt, with two buttons and fur around the bottom and top. He wears a collar with a large bell, and a skeleton pin in his hair. He appears to have black wings, accompanied by a black tail. His feet and fingers are pointed, and his limbs are similar to that of a stick figure.
