Cacodemon (Doom Eternal)

The cacodemon returns as a monster in Doom Eternal, largely retaining its appearance from Doom (2016). It is slightly more red, and now has a pupil in its eye, making its appearance closer to the classic games' incarnation. Its blood has changed to blue in color, a detail taken from the original sprite. More aggressive than the previous version, it is now capable of shooting a rapid sequence of projectiles consecutively, and its bite is accompanied by a lunging motion which extends the range of the attack significantly.

Tactical analysis
It is possible to fire a grenade into the cacodemon's mouth while it is open. This will result in it suffering a cartoonish internal explosion which dramatically inflates its stomach in a fashion reminiscent of the dodongo from . Firing a grenade into the cacodemon's mouth in this way will instantly stagger it and leave it vulnerable to a glory kill.

Like other flying demons, it is weak against the Ballista.

Glory kills

 * The Doom Slayer grabs onto the cacodemon, with left hand on its eye and the right hand on its mouth. He squeezes the cacodemon's eye out of its socket, and the demon howls in agony before exploding.
 * The Doom Slayer grabs onto the cacodemon, pulls its eye out, and then kicks the demon away, causing it to spin.
 * The Doom Slayer stabs the cacodemon's eye and throws it away.

Lore
Cacodemons are native to the Sloughlands, located in the murky depths of Hell. It is aimless and nearly devoid of sensory awareness or cognitive ability of any type beyond its hunger, so it is prone to appear anywhere that might have flesh for it to consume. Ancient Hell lore speaks of mighty cycloptic titans, and Night Sentinel scholars speculated that cacodemons might be the devolved remnants of these titans.
