The show follows the Dinosaucers and their battles against the evil Tyrannos. Each group is composed of intelligent anthropomorphic dinosaurs or other prehistoric reptilian species. The Dinosaucers are also allied with four humans known as the Secret Scouts. The two groups originally come from a planet in a counter-Earth orbit known as Reptilon. Most of the characters are named after the type of prehistoric animal they are based on, or some pun of the name.
Both groups have a central base of operations. The Dinosaucers' base is called Lava Dome and is located in a mountain area, in a dormant volcano. The Tyrannos' base is located under a tar pit. Each of the groups' members save for Teryx and Terrible Dactyl–who can themselves fly–have flying ships in which they can travel and do battle. Most ships actually resemble the personae of their respective owners. Along with their individual ships, both groups have a large mothership of sorts as well.
