I guess what I meant to say was that, hypothetically, if Fatalis were to encounter any of the creatures that we (currently) believe it does not coexist with, it would be an incredibly dangerous opponent, regardless of the plausibility of the scenarios occuring in nature.

Here's the thing, though: we DON'T know much, if at all, about the Fatalis's habitat range. Sure, we can infer they seem to like man-made structures, but there does not exist any true reason a Fatalis could not decide to travel and destroy any area it sees fit. Unlike Dire Miralis and Akantor, who seemed physically incapable of truly leaving their biomes, the Fatalis seems versatile enough to potentially be a nomadic predator like the Deviljho. In fact, I imagine the Fatalis could far surpass the Deviljho as a nomadic hunter, seeing as it 1) is very skilled at flying, which the Deviljho obviously can't compete in, and 2) is even more invincible in a fight.
