Imp/Doom 3

The Imp in Doom 3 is humanoid in shape, has a grey skin and multiple eyes. They behave in an insect-like fashion and can climb walls. These monsters are very common in the game, often teleporting into an area once you have entered it, or performed some action. Most of the times they will ambush the player hiding behind doors or when climbing the roof. They can either throw plasma fireballs from their hands, attack with their claws or make a quick jump scratching the player.
