Three Martian natives are also biker mice. Their world, formerly green and lush, was bought out from under them by the evil Plutarkians, a fishlike species. Modo, Throttle and Vinnie are the rebel leaders who were captured and given to the evil scientist, Dr. Karbunkle, to be experimental animals. They escaped, and made their way to Earth where they discover the Plutarkians are trying to take over Earth, too!
