Dino-Riders

This series pilot introduces the main good guys (Questar, Yungstar, Serena, Gunner, Turret, Mind-Zei, and Llahd) and bad guys (Krulos, Rasp, Hammerhead, and Antor) in the midst of a space chase. Our heroes use their experimental S.T.E.P. to escape their enemies by time traveling back to Prehistoric Earth. It is only after they have begun to build a settlement that they learn that the Rulons went back in time with them and are building a brain boxed dinosaur army. Can the Valorians build up their defenses in time for Krulos's first attack?
