Cacodemon (Doom 2016)

The cacodemon returns in Doom (2016) with an appearance closely matching the original version of the monster. It is a red-colored, floating, round monster with a single glowing green eye and a large mouth full of razor-sharp teeth. Unique to this incarnation are vestigial arms and legs which hang below its body, a reptilian-like neck pouch between its arms, and a rough, armored appearance to its skin, which is studded with horns and small spikes.

Tactical analysis
Like the classic Doom monster, the cacodemon belches red-and-purple balls of lightning-like energy, and can attack the player with bites at close range.
