Another classic Saturday morning cartoon by Hanna-Barbera called The Herculoids. The show first came on the air in 1967 on CBS and had a total of 18 episodes. The show eventually ended its run in 1969 however 11 new episodes were created for the Space Stars show in 1981.
The Herculoids was much like Johnny Quest and Space Ghost as it had more or less the same content and story direction. The series contained eight major characters with three of them being Humanoids and the other five being The Herculoids.
The Herculoids have been seen in other shows such as Space Ghost where it was first introduced. In modern days The Herculoids have been mentioned in Harvey Birdman: Attorney at Law, The Venture Bros and even Family Guy.
