- "A hound it was, an enormous coal-black hound, but not such a hound as mortal eyes have ever seen. Fire burst from its open mouth, its eyes glowed with a smouldering glare, its muzzle and hackles and dewlap were outlined in flickering flame. Never in the delirious dream of a disordered brain could anything more savage, more appalling, more hellish be conceived than that dark form and savage face which broke upon us out of the wall of fog."
- ― The Hound of the Baskervilles
- Hellhound Mimicry
The user is or has the ability to take on the form of a Hellhound, a supernatural canine connected to the Underworld/Hell and/or considered an Omen of Death. Features that have been attributed to hellhounds include black fur, scales, glowing red or sometimes yellow eyes, super strength and/or speed, ghostly or phantom characteristics, foul odor, and sometimes even the ability to speak.
Legend says that if someone is to stare into the eyes of a Hellhound three times or more, that person will definitely die; seeing or hearing it howl may also be either an omen of death or even a cause of death. In cultures that associate afterlife with fire, hellhounds may have fire-based abilities and appearance. They are often assigned to guard the entrances to the world of the dead, such as graveyards and burial grounds, or may undertake other duties related to the afterlife or the supernatural, such as hunting lost souls or guarding a supernatural treasure.
