The original trio of B-Fighters in Juukou B-Fighter. The members use Bio-armor developed by the Earth Academia's brightest and infused with the life force of insects.

The B-Fighters of the first generation sometimes appear and help out the new generation. After destroying the Jamahl, they were transferred to the Cosmo Academia branch. They occasionally aid the New Generation B-Fighters before Guru dies, destroying their ability to become B-Fighters.
