The Brave of Legend Da-Garn

Seiji Takasugi acquires a gemstone named Aurin, the earth's alter ego, which appoints him as commander of eight valiant robots. The Brave robots lie dormant across the world as Brave Stones. Upon Seiji's awakening, they fuse with contemporary people and machines to transform into super robots and swiftly pledge obedience to his directives. Their adversary is Lord OhBoss, an invading force intent on draining the planet's energy. He is opposed by Da-Garn and the other Brave robots, who must stop him to save the world.
