Japanese Plot
The world was nearing its end. An evil organization created the ultimate weapon, Golden Silver, the God of Ruin, to destroy countless cities on Earth from the moon. The Gunstars, who were Red, Blue, Green, and Yellow, were seeing the Earth turn into a living hell before them and fueled by righteous anger, confronted the powerful Golden Silver. After a lengthy and arduous battle, they defeated the evil God of Ruin. To make sure it is never resurrected, they sealed its body on the moon and took the four gems that powered it, and sealed them away in separate areas on Earth. The exhausted Gunstars, having been pushed to their limits, prayed for a new civilization to arrive, and they began their long cryogenic sleep. All that is, except for one.
Time passed and a new civilization was built on Earth. A legend was spread across the land: "Revive the God that sleeps on the moon, and he will guide the most righteous people to Utopia".
General Grey, the commander of the dictatorship calling themselves the "Empire", believed in this legend and attempted to carry it out. So, he sent people to the moon in a battleship called the "Ark", in order to mine for the gems that would call forth the God. It was then that the leader of the underground mining excursion, Dr. Brown, uncovered some capsules, in which the Gunstars were having their stasis.
Once they awakened, they learned of the Empire's plan to revive Golden Silver. Their companion, Green, whom they had remembered being with them up until the very end, had lost his previous memories and was now assisting the Empire in the revival of the God of Ruin.
"We won't let such a tragedy happen again! We'll get back the gems and put a stop to the revival of Golden Silver!"
Once Dr. Brown heard the Gunstars' words, he decided to betray the Empire and promised to help the Gunstars in their battle.
Western Plot
The Gunstar Dynasty has been the protector of the planet Gunstar 9 (G-9) for generations. In his youth, Professor White Gunstar defeated Golden Silver, a destructive android that traveled millions of miles to suck G-9 dry of all its resources. Professor White was able to extract the four famous Mystical Gems, the robot's power source, and imprisoned it on one of G-9's moons.
Years later, a new menace rises. Colonel Red, a vicious dictator, found out that the Gunstars knew the location of the Mystical Gems. One day, Colonel Red kidnapped the Gunstar twins' older brother, Green, and used a mind control device to make Green obey his orders.
With Green's help, Colonel Red amassed all four Mystical Gems, has turned Gunstar 9's peaceful worker droids into deadly menaces, and is now preparing to leave for Gunstar 9's moon to reactivate Golden Silver.
