Your father's brain in a computer. Your body spliced with an alien artifact. The only thing between earth and a queen who's been waiting 2,000 years to conquer it. Koutetsu Jeeg doesn't ask permission to be weird, it just does it, building something that still feels stranger than most super robots that came after. Forty-six episodes of a man learning to pilot himself like a weapon while the stakes keep getting bigger. This is what the genre looked like before it knew what it was doing, and that's exactly why it works.
Hiroshi Shiba was just a talented race car driver until his father is murdered over a mysterious Bronze Bell unearthed from an ancient civilization. Queen Himika, who hails from that bygone era and the Yamatai Kingdom, wants the Bell so she can rule the earth. His father leaves Hiroshi items that let him transform into Steel Jeeg, a full-sized mechanical warrior. With his father's brain placed inside a computer and the help of his assistant Miwa "Micchi" Uzuki, Hiroshi sets out to stop Himika's plans for world domination in this action-packed mecha series from 1975.
