It's seems to be overlooked by other Ghost Pokémon... cough **Gengar** cough.
Duskull is styled after a traditional personification of Death, the Grim Reaper. It resembles a small hooded masked form in a black robe with a crossbones drawing on its back. In its "shiny" alternate coloring, its robe is curiously bright red, possibly inspired by the Devil. Its mask resembles the front of a skull. It also seems to have a single eye that floats between the eye sockets in its mask.
Fun Fact: Duskull is the only Pokémon with Levitate whose evolutions do not have the ability.
