Jonny Quest, also known as The New Adventures of Jonny Quest, is an American animated science fiction action-adventure television series produced by Hanna-Barbera, airing for one season from 1986 to 1987, with thirteen episodes. It is a revival attempt of the original series that ran for twenty-six episodes between 1964-65. A new addition to the team was the rock giant, Hardrock, who was given a formal introduction during the series. He never appeared again after this series, and the concept of a rock giant on the team was mocked in the Jonny Quest: The Real Adventures episode, Rock of Ages.
