The Deathstalker in ep.7 suggests alot of things about the Creatures of Grim: they are effectively immortal(it's hundreds or thousands of years old, based on the paintings); they don't need to eat, at least in the normal sense(it spent most of that time trapped in cave with nothing to eat); and their sole goal in life is seemingly not have children, but to kill humans(it probably could have broken out of the cave within a few years of being imprisoned, but it didn't even try to leave until a human walked right up to it).

That all suggests that the Creatures of Grim have a purpose: to annihilate humanity; something contrary to natural life, which simply seeks to continue existing. In the intro to the whole series didnt it say that the creatures of Grimm were around before man?
