Each of the anime broadcast featured a team of robot pilots variably known as "J9" whose role changed from series to series. Each was also advertised as being the "robot anime version" of another popular fictional motif. In each series, the cast of heroes were voiced by Kazuyuki Sogabe, Kaneto Shiozawa, Katsuji Mori, and Yōko Asagami.
