The cacodemon is a returning enemy which occurs in Doom: The Dark Ages. Two specimens can be briefly seen hovering in the background of a scene in the reveal trailer released on June 9, 2024. In this incarnation, they more strongly resemble the original spider mastermind rather than a cacodemon, but have tentacles instead of legs. It is said that they are hybrids of demons and the denizens of the Cosmic Realm. A cacodemon can generate a psychic shield to protect itself or launch it as a projectile, and strikes with its tentacles at close range.

Lore

Once part of Hell's demonic hierarchy, these demons have been corrupted by The Witch's eldritch power. They are fragments of a hive mind that wander the lowlands, looking for minds to consume so that they can feed their gods with twisted thoughts and memories.

Pre-release

• The monster was first identified as the cacodemon by Bethedsa on April 8, 2025. Before this, it was speculated to be a new monster entirely, possibly a flying version of the arachnotron.
