Doofas the Dinosaur has ruled Dinostria for many years and long ago created the spazicore—a one-way portal into Lord Grok's dimension, used to return the evil Grok sends to Dinostria right back at him. Grok has run out of patience with this arrangement. He has spent the last of his available evil creating two beings, Miaton and Prochun, with a single purpose: destroy Dinostria.
