Mancubus

The Mancubi are enormously bloated, cumbersome but tough demons that look somewhat like extremely overweight humans. They do have some distinct demon features though - all green eyes, deformed feet, pointy teeth and three pairs of nipples. In addition their arms have been replaced by huge, rapid-firing fireball cannons powered by a generator strapped onto their backs. The game manual describes Mancubi like this:
 * The only good thing about fatso is that he's a nice wide target. Good thing, because it takes a lot of hits to puncture him. He pumps out fireballs like there was no tomorrow.

Data

 * 1) The Mancubus fires three salvos of two fireballs at a time.
