Duskull is a pure ghost Type Pokemon, and is the first evolution stage of the Pokemon, Dusknoir. It was first released in the games Ruby and Sapphire, Generation 3. 

Duskull is a classic example of a personification of the human idol of death, the Grim Reaper. It wears a mask, which to many resembles a skull of a dead Pokemon. It has two eyes, both which may be called as "floating" in its sockets. While Duskull is a ghost type, it has one quality that many of the same type do not have, which is bulk. It is a nocturnal Pokemon, and is generally seen out in the night.

Duskull has been known to adapt to many habitats; however, it is usually found in the caves or other dark places.
