The Imp is the basic demonic enemy and common in all of the games because they appear in almost every level, where they appear with a relatively humanoid appearance. In the original games, Imps have brown skin, red eyes, and spikes on their shoulders, elbows and knees. They usually emit a hissing sound when alerted and have 60 HP. They attack at long distance by firing fireballs from their hands, and up close by scratching with sharp claws.
