Space Runaway Ideon (伝説巨神イデオン Densetsu Kyojin Ideon), also known as Legendary Giant God Ideon, was an animated television series that aired on Japanese television from 1980 to 1981, followed by two feature films released in 1982. Ideon was created and directed by Yoshiyuki Tomino, and was the series he produced immediately following his most famous work, Mobile Suit Gundam. Its mechanical designers were Submarine(series) & Higuchi Yuuichi(movies) and its characters were designed by Kogawa Tomonori.
Space Runaway Ideon begins in 2300 AD, far enough in the future that mankind has begun colonizing other planets. On the planet Solo a group of archeologists come across the mysterious remains of the Ideon—three large armored trucks with the ability to transform into the godly mecha. They also come across a large spaceship. At that very moment of discovery, a humanoid alien civilization known as the "Buff Clan" comes across Solo. When the daughter of the Buff Clan's military commander flies down to the planet against orders an interstellar war is triggered. The cities on Solo are obliterated by the Buff Clan soldiers and the survivors, using the Ideon for protection, board the spaceship found with the Ideon (known as the "Solo Ship") and flee. The survivors travel from planet to planet, constantly pursued by the Buff Clan who desire the Ideon for themselves along with the mysterious energy source behind them, known only as "Id" or "Ide". The Ideon is piloted by several Solo Ship crew members, but the main pilot is the series protagonist Cosmo Yuki.
As the crew of the Solo Ship fight and survive further, the true power of the Ideon begins to slowly be revealed with terrifyingly devasatating results. Although the crew often latches onto various hopes and optimism, as the death toll of the crew rises and the devastation surrounding them increases, the crew of the Solo Ship slowly begin to despair. Eventually turned away by their own world out of fear, what fate awaits this lost ship and its inhabitants? (Wikipedia)
