Fan Casting The Chewing Man in American Horror Story: Nowhere

From a twisted and perverse dimension, the Chewing Man has been invoked since the dawn of civilization as a weapon of war. Being summoned by powerful sorcerers he quickly destroys entire cities and takes the bodies of inhabitants to his dark abode. It is said that he is in a different category from God and Devil and cannot be erased by either of them. He only leaves when the last inhabitant of the city is eliminated and the only thing that can lose him is the smell of cat blood, because they are animals that absorb energy and have purity.
