In the future, the "Metal Fight" games are the world's most popular televised sport, with numerous robot contestants vying for the title of Best Metal Fighter in the World. Kurenai Ken, alongside his teammate Saeba Shoko (who was initially adamant), pilots the Super Robot Fighter, Red Baron, and enters the contest with dreams of becoming its champion. However, he must face an army of rivals from around the globe, including Kaizer (who is, in fact, Shoko's supposedly "lost" father, Tetsuo Saeba), the Tetsumen Tou ("Iron Fist" - a reference to the original Red Baron TV series) doctors, Tiger, and ShinRon.
