Jet Saber was the third of the Sabers, and the fourth of the Brave Warriors to be awakened. His Brave Stone was buried within a chunk of ice in Antarctica. Seiji Takasugi retrieved it and brought it with him to Redlone's base (also in Antarctica). He was awakened at the same time when Shuttle Saber was, but what made him the final Saber to be awakened is that he finished his transformation sequence after Shuttle Saber did.

Seiji Takasugi obtained a jewel called "Aurin" which is the earth's alter ego and it has elected him to be the commander of eight brave robots. The Brave robots are sleeping in many parts of the world as "Brave Stones". However, they become super robots by fusing with modern people and machines once Seiji awakens them and they soon follow his instructions. Their enemy is Lord Oh-Boss who is an invader who aims at stealing the planet's energy with the aid of his subordinates that Da-Garn and the other brave robots must stop in order to save the world.<br><br>
