The Cosmic Quetzalcoatlus is a Quetzalcoatlus northropi which has been augmented by the Cosmic Gem. When the Stakslees discovered the gem, it aided them in learning how to harness new powers and abilities through it.
Currently, it resides on a planet which was specially created by the Super Eon Annihilator to emulate Earth’s Late Cretaceous Period. It lives there with the Stakslees.
