This demonic entity is more than a millenia in age and when establishing the Wager was in the form of a humanoid with dark, short, coarse fur and spiral horns, like that of a ram. A large hump adorned his back and its hands possessed sharp claws.
For the Wager it created the Fearsome Fist fo Farallah, an artifact that later powered Carnivore, making him into an Exemplar. Unfortunately for Farallah however, his influence was driven out of Carnivore by the efforts of Captain America and Bedlam.
The incantation that calls upon Farallah for its power is Fangs of Farallah.
Those are jaws of fangs that can bite almost through anything, including energy.
