About Grendizer
UFO Robot Grendizer ran for 74 episodes from 1975 to 1977 and follows Duke Fleed as he defends Earth from the Vegan invasion. Grendizer U from 2024 retells the story with modern animation as a separate continuity, so it can be watched on its own.
Good to know
The 1970s films are short non-canonical crossovers with Great Mazinger and Getter Robo G, so treat them as optional extras. Akai Yuuhi no Taiketsu is just episode 49 of the TV series shown at a festival, so it is not listed separately.
