Space Runaway Ideon episodes

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.

The Ideon's 3 vessels revert to their normal forms after the battle is over and are equipped with powerful weapons under the direction of Bes. Bes later runs into Karala in the woods, mistaking her for a colonist. Gije leads an attack on Solo to rescue Karala, and totally destroys Solo's capital, New Lopia. Fleeing from the attack, a group of children including a baby, Piper Lou, board the Ideon, which finds the strength to fight off the Buff Clan once again. Sheryl meanwhile heads to the second excavation site, where a giant spaceship has been discovered.

Karala is reunited with Mayaya aboard the Solo Ship. Gije and Damido request help from their commander, Abadede, and launch yet another attack on Solo in order to rescue Karala. Bes discovers that Karala and Mayaya are actually Buff Clan aliens. During the ensuing battle with the Buff Clan, the Solo Ship rises from out of the ground.
