Mancubus (Doom 3)

The Doom 3 equivalent of the Mancubus is more elephant-like, with what appears to be a trunk extending from under the eyes and into the chest and "tusks" on each side of the "trunk", however, if one uses the noclip cheat, one can see hooks which have suckers where the trunk begins, indicating the trunks are actually tentacles. This shows that the Mancubus' design was based on Cthulu.

Like the original version, it has a fireball launcher for each arm, but unlike the original, it doesn't fire the two launchers simultaneously, firing each in turn instead. The Doom 3 Mancubus is tougher than its classic version, taking as many as six direct rocket hits to kill, making it the toughest (but also one of the slowest) non-boss creature in the game.

These monsters are usually accompanied by Cherubs, making some think they are the Mancubus' offspring.
