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. 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 fantasy. Plot On the planet Amzot (renamed Quasar in the revival), the space barbarian family Zandor, Tara and son Dorno fight alongside their giant pets the Herculoids—laser dragon Zok, space rhinoceros Tundro, rock ape Igoo and the shape-shifting Gloop and his son Gleep—to keep their planet safe from invading robots, mad scientists and mutants. The diverse team fought an endless battle against a stream of villains including, according to Children's Television: The First Thirty-Five Years, "the Faceless People, Destroyer Ants, Raider Apes, Mutoids, Arnoids, Zorbots, the Mekkano mechanical men and the Ogs, a strange form of vegetable life." Characters There are eight regular characters who make up the Herculoids: The Herculoids Humans The three humans were the only ones who could communicate in English. Zandor (voiced by Mike Road) – The protector of Amzot/Quasar, and 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 1980s revival of the series. Creatures The five creature characters of The Herculoids are: Zok (voiced by Mike Road) – A bat-winged laser 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 also breathe fire. Igoo (voiced by Mike Road) – A rock ape. An extremely large and powerful simian, he has extremely dense, rocklike 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, except when his loved ones or home are threatened, and displays great fondness of and devotion to Tara in
