The Herculoids are an alien race. They are the aliens that built the Herculoid Automaton.
- It's possible that The Herculoids referenced in the episode was supposed to be the aliens from the planet Quasar in the land of Amzot, as seen in the 1960s Hanna-Barbera animated series The Herculoids. If this is the case, that would mean that The Herculoids, Space Ghost, Birdman, The Galaxy Trio, Dynomutt, Mighty Mightor, and other connected shows are all part of the Earth-1A universe. And ironically Alex Toth was also involved with all those shows as well. Not to mention that DC Comics has also published a Space Ghost comic series.
