Arch-vile

"One of the worst of a bad lot. You can't think of enough rotten things to say about him. He's fast, hard to kill, casts spells, and resurrects dead monsters! At least these suckers are rare."

- Doom II Manual description

Arch-viles are very tall, emaciated-looking humanoid figures with a grotesque appearance, including stigmata. They also have no flesh around their abdomens (with the exception of those in Doom 3), revealing some of their ribcage and spinal column. The Arch-viles first make their appearance in Doom II in MAP11: Circle of Death. They went on to be seen in Doom 3, Doom RPG, and Doom Eternal.

Inspiration and development
The idea and name for the Arch-vile came from Sandy Petersen.

Bobby Prince said: "The Arch-vile is an evil healer. Anyone getting in his way is blasted with fire and disintegrated. This includes other demons. But, after he has wrought his destruction, he then goes around and reanimates all of the demons. Because of this interesting dual personality, I decided to give him a very evil laugh as an active sound. For his death sound, I recorded a young girl saying 'why,' pitch shifted it down and mixed it with other sounds. The Arch-vile just doesn't understand why anyone would want to kill him as he sees himself as only doing good for his fellow demon."
