Dorno is the son of Zandor, leader of the Herculoids, and his wife Tara, a family of three humans and their five very powerful pet creatures defending their jungle planet. The Herculoids were the subjects of an American animated television series, which debuted in 1967 and was revived in 1981 on CBS and produced by Hanna-Barbera Productions.
Dorno has a cute, boyish face, long, blond hair, and a slender, athletic physique. His shirtless Herculoids outfit consists of a pair of brown boots, a light, blue skirt and neck collar, and a gold belt and wrist bands. At his age, he is growing taller and more attractive and gaining better muscle definition and athletic ability. He is also developing more self-esteem and self-confidence and taking more risks.
Due to his youth and his lack of special powers, Dorno is certainly one of the most vulnerable members of the Herculoids and is frequently a weak link which their opponents seek to target.
In this episode, the Bubblemen capture Zandor and Tara and take them to their undersea lair. Dorno follows the Bubblemen with Zok and Gleep, rescues his parents, and escape in a bubblecraft. The Bubblemen pursue them to the surface, where they are defeated by the Herculoids.
Dorno is inside a bubblecraft with Zandor, Tara, and Gleep which is shot down while they are trying to escape.
Dorno's best scenes are shooting energy rocks with his slingshot in the Bubblemen's undersea lair while rescuing his parents.
