Humanoid aliens known as the Buff Clan discover the Earth colony planet Solo, where archeologists have found 3 large armored trucks from the 'Sixth Civilization' a long extinct alien civilization. Karala Ajiba, daughter of the Buff Clan military commander heads down to Solo along with her assistant Mayaya and is pursued by her colleagues Gije Zaral and Damido Pechi. A panicked Buff Clan soldier attacks one of the Solo excavation sites, triggering an interstellar war. Seeking cover, some of the colonists including Cosmo Yuki, Kasha Imhof, Bes Jordan and Sheryl Formosa board the armored trucks, which combine to form the god-like mecha, Ideon, which fights off the enemy.
