Behavior
Duskull is primarily a nocturnal Pokémon. People say that this Pokémon will spirit-away disobedient children.
Duskull also had a brief appearance in Get the Show on the Road. While May was on her way to Prof. Birch's, Duskull popped up right in front of May and scared her out of wits.
Two Duskull were among the several Ghost Pokémon living in abandoned mine in Fear Factor Phony. Since the Ghost Pokémon couldn't stand the partying Psychic Pokémon in the nearby town, Team Rocket decided to help the Ghosts because they knew what its like to "lose sleep over a bunch of twerps."
Duskull can pass through any wall no matter how thick it may be. Once this Pokémon chooses a target, it will doggedly pursue the intended victim until the break of dawn.
Duskull wanders lost among the deep darkness of midnight. There is an oft-told admonishment given to misbehaving children that this Pokémon will spirit away bad children who earn scoldings from their mothers.
A glare from its single scarlet eye makes even burly grown-ups freeze in utter fear. It is a nocturnal Pokémon that roams about under the cloak of darkness.
Duskull may be based on the Grim Reaper or the bogeyman. The Japanese bogeyman is called the Namahage.
Name origin
Duskull's name is probably a combination of dusk and skull. Its Japanese name is a combination of 妖魔 yōma, ghost and 悪 waru, bad thing/person. It is also possible that it is derived from 夜回り yomawari, night watch(man). Its French name refers to its skull-mask, and its German name is similar to twilight.
