The Herculoids is an action cartoon series produced by Hanna-Barbera in 1967 for CBS.


The Herculoids featured the warrior king Zandor, his wife Tara, and their son Dorno. These three appeared to be the only human inhabitants of their primitive planet. When trouble arose, Zandor summoned a small army of exotic beasts: Igoo, an giant ape with nearly-invulnerable rock-like skin; Zok, a space dragon who generated laser beams from his eyes and tail; Tundro, a dinosaur-rhinoceros hybrid with impenetrable armor and the ability to shoot explosive energy rocks from the horn on his head, and Gloop and Gleep, a pair of protoplasmic shape-shifters. The Herculoids all displayed human-level intelligence, were able to understand human speech and employed impressive combat techniques and teamwork in battle.

The Herculoids later appeared in all new adventures in NBC's Space Stars, often crossing over with Space Ghost, Teen Force and Astro and the Space Mutts.

Comic Books

The Herculoids appeared in several comic books:

  • In the late 1960s, they appeared in issues #1, #2 and #4 through #7 of Hanna-Barbera TV Super Heroes.
  • In 1978, they appeared in Marvel Comics' TV Stars comic book.
  • From 1997 to 1999, they appeared in four issues of DC Comics' Cartoon Network Presents.

Continuity with Space Stars

The Space Stars series included the Herculoids in its canon to show that Zandor and his family and friends were well known throughout the galaxy, and good friends of Space Ghost and the Teen Force.

But exactly what had originally made Zandor, Tara and Dorno as anti-technological and as primitivistic as they were shown to be was never explained in any of the episodes.


On 14 June 2011, Warner Archive released The Herculoids: The Complete Original Animated Series on DVD in Region 1 as part of its Hanna–Barbera Classics Collection. This is a Manufacture-on-Demand (MOD) release, available exclusively through Warner's online store and Amazon.com. On 27 July 2021, the series will be released on Blu-ray.
