Summoned Wolf

Hellhounds (aka as Wolves) are creatures summoned by Marauders in Doom Eternal.

Background
Hellhounds are the spirits of former wolves belonging to the corrupted Marauders.

The Marauder will sometimes summon an orange spectral Hellhound after deploying his sheild (to block damage incoming from either the slayer or other demons) which chases you and delivers biting damage. While more of a nuisance than a threat, damage from the Hellhound can add up quickly and distract you from the fight at hand.

In multiplayer matches the "Wolf" is an attack the Maruader can unleash at any time. Attacking an enemy Slayer five times wards the Milestone: "Hell Hound."
