The Herculoids is an American Saturday-morning animated-cartoon television series, created and designed by Alex Toth, that was produced by Hanna-Barbera Productions. The show debuted on September 9, 1967 on CBS.[1] Hanna-Barbera produced one season for the original airing of the show, although the original 18 episodes were rerun during the 1968–69 television season, with The Herculoids ending its run on September 6, 1969.

Eleven new episodes were produced in 1981 as part of the Space Stars show. The plotlines are rooted in science fiction, and have story direction and content similar to Jonny Quest and Space Ghost. This series is set on the distant planet Amzot (renamed Quasar in the Space Stars episodes). The name "Amzot" was first mentioned in the Space Ghost episode "The Molten Monsters of Moltar" (in which the Herculoids made a brief guest appearance) and in the series proper in the "Time Creatures" episode.


The Herculoids battled to defend their planet from menaces on Amzot/Quasar and from outer space. All of the Herculoids displayed Human-level intelligence—employing precision teamwork and complex tactics—as well as emotions, and Zandor and Tara both displayed a working knowledge of complex alien technologies as well as the ability to pilot interstellar spacecraft.

But essentially, Zandor, Tara, Dorno, and the Herculoids were all apparently fighting to keep Amzot/Quasar a technology-free, primitive planet. This is further indicated by the pseudo-barbarian outfits of Zandor, Tara, and Dorno and the fact that technology was used mainly by the various villains, but rarely if ever by the heroes.

Although the "speech" of their companions was limited and repetitive, Zandor, Tara and Dorno demonstrated that Gloop and Gleep, at least, had a comprehensive mode of communication, and that they could at least understand and interpret this language (c.f. "The Mutoids:" "Gleep says that the aliens who landed are attacking Dorno and Tundro"). The "voices" used in the shows were actually brief tracks supplied by two actors and reused throughout the series, in keeping with Hanna-Barbera's thrifty ethos.

A number of episodes featured alien invaders who came to Amzot/Quasar to seek revenge against Zandor for an unspecified battle or adventure from the past. All were apparently technocratic, and the aliens's grudges seemed basically to boil down to them being stymied in their attempts at bringing technology to Amzot/Quasar, which the apparently primitivistic Zandor wanted to avoid.

The show's opening theme was a fully orchestral composition, suggesting uncommon heroism. An alternative opening theme was also utilized for some episodes. All of the show's incidental music was recycled from Jonny Quest.[citation needed]

In some of the seasons, the episodes opened with the following narration: "Somewhere out in space live The Herculoids...Zok the laser-ray dragon! Igoo the giant rock ape! Tundro the tremendous! Gloop and Gleep, the formless fearless wonders! With Zandor their leader, and his wife, Tara, and son, Dorno, they team up to protect their planet from sinister invaders! All-strong! All-brave! All-heroes!! They are The Herculoids!!!"

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.


There are eight regular characters:


The three humanoid characters were the only ones who could communicate in English.

  • Zandor (voiced by Mike Road) - The protector of Amzot/Quasar. Leader of The Herculoids.
  • Tara (voiced by Virginia Gregg) - Zandor's wife.
  • Dorno (voiced by Ted Eccles in the original series, Sparky Marcus in 1981) - Son of Zandor and Tara. Despite being their son, he still refers to them by their first names, rather than "Mother" and "Father." However this changed in the 80's revival of the series.


The five creature characters of The Herculoids are:

  • Zok (voiced by Mike Road) - A flying space dragon. He can emit laser beams from his eyes and tail. His eyes also produce a "nega-beam" that can neutralize certain energy attacks. Zok can survive in space unaided, is capable of interstellar travel, and can breathe fire.
  • Igoo (voiced by Mike Road) - A rock ape. An extremely large and powerful simian, he has extremely dense rock-like skin and is nearly invulnerable to harm. In one episode, Igoo wades through a pond of molten lava. Igoo has a kind and gentle temperament as well as a great fondness and devotion for Tara, and would do anything for her.
  • Tundro (voiced by Mike Road) - A ten-legged, four-horned rhino/triceratops hybrid. He can shoot explosive energy rocks from his cannon-horn (Zandor, Tara, and Dorno also occasionally shoot similar rocks with slingshots). His natural armor-plating is exceptionally strong, similar to Igoo's rock skin. His legs have the ability to extend to a remarkable length, somewhat like stilts. He can also spin his head at blinding speed, allowing him to drill through solid rock, and has the ability to make magnificent leaps.
  • Gloop and Gleep (both voiced by Don Messick) - Two protoplasmic creatures. They are able to absorb and deflect energy blasts and laser beams, often placing themselves between attackers and other Herculoids to act as shields. They can also form shapes including, but not limited to: cushions, trampolines or parachutes to break falls; stretching themselves between tree limbs or rocks to act as slingshots; encircling an attacker's limbs to restrain them, or the entire body to squeeze and render them unconscious. Gloop is the larger of the two.

Other appearances

thumb|150px|left|Outside of their own TV series, The Herculoids also appeared in comic books such as this issue of Cartoon Network Presents #17, from 1999.

Outside of their own TV series, the Herculoids made appearances in various comic books through the years. In 1968-1969 they appeared in issues #1-2, and issues #4-7 of the series Hanna-Barbera Super TV Heroes. In 1978 they appeared in issue #3 of the Marvel Comics series TV Stars. Finally between 1997-1999 they appeared in issues #5, #9, #13 and #17 of the DC Comics series Cartoon Network Presents.[2]

Roughly contemporaneous to their own series premiere, the Herculoids made an appearance in an episode of Space Ghost, "The Molten Monsters of Moltar" (sources are unclear and/or inconsistent as to exact airdates). In the "Council of Doom" story arc, Space Ghost, while battling the combined might of all of his enemies, meets a number of Hanna-Barbera heroes just as they were debuting in their own respective series. Along with the Herculoids were Shazzan, Moby Dick and the Mighty Mightor, the last two sharing one series.

Several episodes of Space Ghost Coast to Coast mention or show the Herculoids. In "Lawsuit", Space Ghost mentions the Herculoids planet. In the episode "Sequel", he goes to their planet and refers to it as a "rotten hippie monster commune" after they demand he leave while pelting him with stones.[3]

Gloop is mentioned by name and features prominently in the Sealab 2021 episode "Hail, Squishface".

Gloop makes several guest appearances on Harvey Birdman: Attorney at Law as well. Gleep is mentioned at one point but he does make cameos in "Mindless" and "Juror in Court", and Zok makes an appearance in "Peanut Pubeerty" (Phil Ken Sebben throws a graph chart at him). Tundro makes an appearance in "Beyond the Valley of the Dinosaurs" firing his energy rocks at Phil Ken Sebben, who forgot to close the hot tub time portal to prehistoric times, Tara appears on the evolution chart in between Fred Flintstone and Race Bannon in "Evolutionary War".

The Herculoids is mentioned in an episode of The Venture Bros., where an old "fan letter" of Dr. Venture to the show is discovered. Upon reading, the letter is revealed to be more akin to hate mail; young Rusty Venture called the Herculoids hippies for not fighting in Vietnam.

Tundro and Gloop appear in an episode of Family Guy, "8 Simple Rules for Buying My Teenage Daughter". In the scene, Gloop fails to get a babysitting job from Lois. In protest, Tundro shows up and fires his energy rocks at Lois. (NOTE: The Herculoids is owned by Hanna–Barbera, not Fox parent News Corp..)

Gloop and Gleep appeared in a cameo as captured prisoners of a hostile alien race in the Dexter's Laboratory episode "Mis-Placed in Space".
