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 on and fur around the bottom and top. He wears a collar with a large bell, and a skeleton pin in his hair. It looks like he has black wings, accompanied by his black tail. His feet and fingers are pointed, and his limbs are similar to that of a skin figure.
