Doom Hunter

"I thought you'd appreciate the sentry I chose. The great Agaddon Hunters from the Telos Realm, though long thought to be extinct, created to hunt only the Slayer and his Night Sentinels during the Unholy Crusade... Some improvements on the design have been made; enjoy what is undoubtedly my finest work."

- Deag Ranak

The Doom Hunter is a new type of enemy introduced in Doom Eternal, and three of them serve as the first boss of the game. The Doom Hunter is a type of demon called the Agaddon Hunter from the Telos Realm, which was specifically designed to hunt the Doom Slayer and his Night Sentinels during the Unholy Crusade. It comes equipped with an arm-cannon, a twin-barred chainsaw arm, and a rocket barrage attack. It hovers on a hovertank-style "sled".

While the Agaddon Hunter was supposedly rendered extinct long ago, it is been stated that the remains of the Doom Hunter were found and excavated in a remote location in the Antarctic by the UAC cultists, where it was in hibernation that lasted for millennia. When it was excavated, the Doom Hunter was revived and mechanically augmented by both the cultists and Deag Ranak.

Combat Characteristics
Doom Hunters are Super Heavy demons that are armed with a wide variety of attacks which allow them to deal damage at all ranges. Their rocket boosters grant them limited flight. The Doom Hunter's upper body is protected by a plasma shield that blocks all damage. The shield can be destroyed temporarily by using cell weapons like the Plasma Rifle, but will regenerate after some time. Its sled can be targeted without destroying its shield, which deals damage to the Doom Hunter.
 * Slashes at the Slayer with its chainsaw arm, dealing heavy melee damage.
 * Uses its arm cannon to shoot fireballs at the Slayer.
 * Uses the two guns mounted on its sled to shoot a barrage of bullets.
 * Fires a rocket barrage from the launchers on its sled. These rockets will home in on the Slayer, but their tracking can be shaken off by dashing or double-jumping.

Once the Doom Hunter has taken enough damage, it will say "CRITICAL DAMAGE" and abandon its sled, flying with only its upper body. With its sled gone, it loses access to its machine gun and rocket attacks, as well as its shield, but becomes more mobile and aggressive.

Trivia

 * It bears some resemblance to Sabaoth from Doom 3 (a humanoid on treads equipped with ranged weaponry), the Strogg Heavy Hover Tank from Quake IV, and the Necron Destroyer from Warhammer 40,000.
