Feral Demon Grunt

The feral hordes of demons are nothing more than mere animals, demons who simply did not have enough willpower to think for themselves after the events of 1994.
They travel in hordes, comsuming whatever they find in their path to sate their hunger.

When a demon's mortal shell perishes, the soul is returned to it's native layer of hell and attaches to the ground, slowly birthing a new body from the soil.
Unless killed by an weapon blessed with holy fire, all demons are effectively immortal.
