Jonny è un ragazzino che accompagna il padre scienziato, assieme alla guardia del corpo Race Bannon e all'amico Hadji, in una serie di avventure in giro per il mondo, sempre rivolte a sventare qualche malvagia cospirazione.
Hank e Dean Venture, con il loro padre Doctor Venture e la fedele guardia del corpo Brock Samson, intraprendono avventure selvagge affrontando megalomani, zombi e ninja sospettosi, tutto per la gloria dell'avventura. O qualcosa di simile.
Jonny Quest – often casually referred to as The Adventures of Jonny Quest – is an American animated science fiction adventure television series about a boy who accompanies his scientist father on extraordinary adventures. It was produced by Hanna-Barbera Productions for Screen Gems, and created and designed by comic book artist Doug Wildey.
Inspired by radio serials and comics in the action-adventure genre, it featured more realistic art, characters, and stories than Hanna-Barbera's previous cartoon programs. It was the first of several Hanna-Barbera action-based adventure shows – which would later include Space Ghost, The Herculoids, and Birdman and the Galaxy Trio – and ran on ABC in prime time on early Friday nights for one season in 1964–1965.
The New Adventures of Jonny Quest was a 1980s continuation of Hanna-Barbera's Jonny Quest animated television series from the 1960s. Debuting in 1986 as part of The Funtastic World of Hanna-Barbera's 2nd season, syndication package, this new Jonny Quest series could be seen as the second season to a program that originally aired from 1964-1965 on ABC.
