Humanity's pursuit of knowledge leads them to the planet Solo, where they find mysterious remains of a long dead alien civilization, including the 3 part super robot 'Ideon', and a powerful warship. Using these, the Earthlings sent to investigate the ruins defend themselves in their constant conflicts against powerful aliens called the Buff Clan, who are in pursuit of 'Id', the mysterious energy that powers the Ideon.
Ideon was the biggest influence for Neon Genesis Evangelion.
Ideon was originally to be 43 episodes and was fully planned for such. It unfortunately had the plug pulled after 39.
Ideon was the project Yoshiyuki Tomino worked on directly after the cancellation of the original Mobile Suit Gundam.
