A series of unexplained disasters at sea prompts an investigation by the premier Earth defense force UNICORN. Agent U3, Minami Jyurou is dispatched from UNICORN (Japan Division) to the location of the disasters. There he meets up with a boy traveling alone. His name is Kusama Daisaku. Suddenly, the ship that they are traveling on is violently attacked by a giant sea creature. Minami and Kusama Daisaku barely survive the attack and drift ashore onto a mysterious island.

The island turns out to be the secret headquarters for the sinister terrorist organization BF Dan (Big Fire Organization) who serves the invading alien conqueror Emperor Guillotine. Emperor Guillotine has commissioned the creation of the most powerful robot the world has ever seen. To his end he has captured famed scientist Dr. Garulcher to build the robot.

Minami and Kusama Daisaku escape their confines and attempt to flee the island. Meeting up with Dr. Garulcher, Kusama Daisaku is given a watch controller. Dr. Garulcher asks Kusama Daisaku to speak into the watch. This simple action forever binds “Giant Robo” to Kusama Daisaku. Dr. Garulcher is killed by BF Dan for his betrayal.

Minami and Kusama Daisaku escape BF Headquarters with “Giant Robo” and eventually return to UNICORN headquarters where Kusama Daisaku is recruited as an Agent and given the code number “U-7”.

Together with Giant Robo, Kusama Daisaku battles Emperor Guillotine and his galactic minions for the safety of Japan and the World.
