Some bovine incubus in ancient days engendered a whole race of monster cattle creatures that have plagued the world.  Some go about on all fours, like some sort of scale-covered aurochs of immense power, others have a more human-like body with a bull-like head (sometimes call Minotaurs); both sorts belong to the same devil-spawned species.
