The Valorians were a peaceful race that had lived in harmony on the planet Valoria until the evil Rulons came and attacked them. The Valorians tried to escape from the Rulon assault and attempted to use their "Space Time Energy Projector" (S.T.E.P.) to do so, however something went wrong and the S.T.E.P malfunctioned and caused the planet to merge with Earth as it was 100 million years ago. The Valorians use their AMP necklaces to communicate with the dinosaurs and befriend them. The Rulons, led by their leader Krulos, on the other hand used brainwashing devices known as brain-boxes to control dinosaurs for their own ends.
