The Doom Hunter is new type of enemy introduced in Doom Eternal. The Doom Hunter is a type of demon called the Agardon Hunter from the terror realm. It comes equipped with an arm-cannon, a twin-barred chainsaw arm, and a rocket barrage attack. It hovers on a hovertank-style platform, meaning it has lower mobility but possibly heavier armor.
After the Unholy Crusade, all Agardon Hunters are rendered extinct but one that was designed to hunt the Doom Slayer.
