The Hellhound is a powerful shapeshifter within the Teen Wolf universe that appears to protect the secrecy of the supernatural.
Lydia found a book that described a mythical Hellhound:
'“Woden’s Hunt, also known as the Wild Ride or Wild Hunt. A myth of devilish riders in the sky accompanied by black dogs, spectral beasts whose eyes glowed with fire... A Bearer of Death and Guardian of the Supernatural, the black dog is also known by its more common name, the Hellhound."
The only Hellhound seen so far is an entity inside Jordan Parrish, however, he had no idea of his alter ego. Whenever the Hellhound took control, Parrish would black out and remember little to no details.
- Parrish attacks Deputy Haige after he tried to kill him by setting him on fire.
- Parrish began to cover up the supernatural by stealing the dead chimeras and placed them at the Nemeton.
His eyes glow orange/yellow and he is impervious to flame
Thus far, a Hellhound has an ability generate flames and extreme heat around his body. He seems to heal quickly with his wounds giving off heat and smoke during the process.
Like most shapeshifters, the Hellhound has fangs and long claws. It appears that its "internal fire" actually cracks Parrish's skin when activated.
The Hellhound appears unaffected by Kanima venom and electricity.
It is incredibly strong as it was able to flip Stiles' Jeep and to bend the heated bars of a jail cell.
A Hellhound was able to block a Banshee's scream by wrapping itself around her to absorb a portion of the shock wave.
