Austral Island is located 2,000 km south from Samoa islands. The existence of the island was removed from the official records, and Tagami Yu made a journey to search for the reason. He sailed for the island with Dr. Waive who was his father's friend, Doris who is the daughter of Dr. Waive, and Captain who is the friend of Dr. Waive. On their way to the island, GAIL, the international conglomerate, and gangster, Cougar Connection lead by Lady Lynx attacked them. They managed to arrive at the island, but suddenly a mysterious monster began to attack them. When they became ready for death, a blue giant robot appeared. It destroyed the monster and saved them. Although it was an existence far beyond human knowledge, it reminded Yu of something warm and familiar. It was Giant Gorg which is called "Messenger of the God" by the inhabitants of the island. Escaping from the attack of GAIL's assault team, Gorg guided Yu into the underworld. There, he found alien's relic and an alien who woke up after 30,000 years' sleep.

A meteor strikes the Earth and is found to emanate a powerful new energy called Beamler, which is used to power a battle robot, GoShogun, and a teleporting fortress, Good Thunder. The Docougar Crime Syndicate, lead by crime lord Neo Neros, try to steal the secret of the energy from the inventor of GoShogun, but he kills himself rather than let them acquire it. His son is targeted by Neo Neros next, but he is taken in by the crew aboard Good Thunder, who travel the world fighting NeoNeros's forces with GoShogun.

In the year 2005, a race of alien monsters called Zonders emerge from underground and launch a series of attacks on the city of Tokyo. The only defense against these creatures is the secret agency known as the Gutsy Geoid Guard (or 3G) and their ultimate weapon, the awesome giant robot GaoGaiGar. GaoGaiGar's pilot, Guy Shishio, is a former astronaut who was nearly killed two years before when the Zonders first crashed to earth. Guy's life was spared when a mysterious robot lion called Galeon pulled him from the burning shuttle and brought him to Earth. Guy's father, Leo, then used Galeon's technology to rebuild his shattered son as a cyborg, in the hopes that he could stop the aliens when they appear. Now, with Galeon as its core, GaoGaiGar fights to protect Earth. He is aided by a team of transforming robots and by a young boy named Mamoru, who has the power to purify the Zonders' cores, and seems to be connected to the mysterious Galeon.
