The Mancubus (collectively referred to as Mancubi) is a fat, cybernetic humanoid demon which was introduced in Doom II. They have fireball launchers bolted directly onto both arms, and fuel tanks for the weapons mounted on their backs. They have 600 HP. They move slowly but it is more difficult to avoid their attacks of multiple, spread-out fireballs than the singular fireball attacks of some other enemies. They are reasonably common in Doom II, with their first appearance in the seventh level. The Doom II manual remarks that their only positive trait is that they are "a nice wide target".
