Trava is an ex-military Power user, which is a form of mech-ship that enhances the pilot's abilities. Together with his mechanic and ex-military peer Shinkai, they travel to planets as surveyors. Trava's ultimate goal is to enter "Fist Planet," a Power fighting tournament with a grand prize of credits measured in billions.

Trava also made an appearance in Takeshi Koike's later work with MADHOUSE, in the film Redline. He and Shinkai appear as racers with the same general goal as in Trava.
