Prince Dorno is the human son of Queen Tara and King Zandor, the husband and wife leaders of the Herculoids, a pulp sci fi team of wondrous beasts and their human companions. The Herculoids was a popular animated Saturday morning television series in the 1960s; though its plots were formulaic and uncomplicated, the series more than made up for it with charm, verve, and creativity!
The Herculoids all reside on the faraway planet Amzot (renamed Quasar for unknown reasons when the series was brought back a decade and a half later).
Dorno spends much of his time with Gleep. When fighting with the Herculoids against alien menaces, Dorno uses a slingshot to hurl exploding energy rocks at aggressors. Dorno is also memorable for being one of the few Saturday morning cartoon children to refer to parents on a first-name basis.
