This is a creature I'm working on right now. Between the HP Lovecraft that I'm reading and the MTG that I'm playing, I've had a lot of creepy horrors floating around my head, and this one is by far my favorite. The first description of it that I made was a flying, carnivorous, demon manta ray; and I think I have so far achieved that vision. I'm doing it low poly (around 1800 right now) and I plan to sculpt it and bake out some normals to make it look pretty. I tossed a simple skeleton on the upper images and posed it in mid attack because I think it looks cooler.
