Flash Gordon (also known as The Adventures of Flash Gordon and even The New Adventures of Flash Gordon) was an adaptation of the comic strip Flash Gordon made in the 1970s by Filmation, the people who did Star Trek: The Animated Series. Perhaps best described as a children's version of a sketchy rock album cover come to life, with lion-men instead of ligers. The series had a movie-length pilot, Flash Gordon: The Greatest Adventure of All, which for some reason was not aired until after the rest of the series.
