Summoned Wolf

Hellhounds are creatures summoned by Marauders in Doom Eternal.

Background
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.
