Halfway through the story the Demon Empire's master, Barao, is released from his statue prison and intends to finish what he started twelve thousand years earlier.

Powers include an extendable boxing glove (later two), claw hands for bashing, can be used as a submarine, a slingshot in the torso, and explosives attached to balloons.

In episode 41 he begins to regain his memories due to the resurrection of Princess Lemuria (daughter of King Ra Mu and mother of Akira).

For the first half of the series his powers included instilling life into rocks to create fossil beasts and eye heat rays when he was in his statue form until episode 27.

Upon being released his powers included forming an entire island in a matter of seconds dubbed Demon Isle, psychically freezing weapons in mid air, seeing into other dimension, causing fissures, fusing colossal monsters together, manipulation of the elements, hand lightning bolts and energy beams, mouth flames that create flaming tornadoes, purple horn energy bolts and balls, a bow and arrow, a barbed boomerang, summoning flames from the middle cave of his island, a giant scythe, blade resistance, levitation, constricting roots from the lower half of his body, and a pair of broadswords with hidden saw blades.

A low-budget Korean film called Space Thunder Kids features a robot whose design appears to be a copy of Raideen's.

In this remake, Saiga Junki, a high school student with a gift in mathematics, learns that his archaeologist father, who disappeared years earlier, has died.

Later in 1976, Brave Raideen began running on KMUV-TV in Sacramento, California (Sunday nights; timeslot to be confirmed), as part of the station's Japanese-American programming.

The series also aired similarly in Chicago (station and dates to be confirmed), as well as broadcast as part of the Japanese programming on New York City's WNJU.
