Retro Trailer: Space Runaway Ideon: Be Invoked (1982) by Yoshiyuki Tomino

For years, the crew of the Solo Ship has been at war, and on the run, from their enemies, the Buff Clan. The Solo Ship has a major weapon at their disposal: a mysterious, supernatural robot known as the Ideon. However, the Buff Clan is working on their latest weapon: the Ganda Rowa, a powerful warship that might be even more powerful than the Ideon. Meanwhile, Karala, a member of the Solo crew and a former member of the Buff Clan, discovers that she is pregnant. She believes that this child, a messiah, could put an end to the conflict between the two factions. But a side-effect is that this child makes the Ideon more powerful, and so the war tragically escalates until the only thing a war causes – doom, death, and destruction – are manifested.
