Space Heroes is a fictional, animated T.V show in Teenage Mutant Ninja Turtles. It is Leonardo's favorite show, and he wants to be just like the main character in it, Captain Ryan. Raphael thinks the show is stupid, and calls Leo "Hero Boy" because Leo acts just like Captain Ryan sometimes. The show is a parody of other space shows and movies such as Star Wars and Star Trek.
- The art style of the cartoon is a parody of Filmation's Star Trek: The Animated Series
- The show has a running gag where the Captain slaps a panicky ensign, even when it isn't actually called for.
