The Crater Ouroboros is a long-serpent like creature covered in several bony plates everywhere except for its underbelly. It has no long legs and simply hovers among the clouds. Wheras the other Remnants move in a specific pattern, Crater Ouroboros moves in a circle. It has a large mouth and a bright pink tongue. It has eyes on the side of its head with hot pink irises. And long, wavy tentacles protruding from under the creature's head and a little ways further down it's body.
