King Goobot

King Goobot was one of Jimmy Neutron's countless enemies. Goobot was a Yolkian who served as the chief antagonist of the film Jimmy Neutron: Boy Genius. In the film, he kidnaps all the children's parents and tried to feed them to Poultra, a humongous alien chicken. He had a brother named Ooblar, whom he later traded. He was also the leader of the League of Villains, whose goal was to get revenge on Jimmy Neutron. He was later trapped in the Cretaceous period along with the other antagonists, and presumably remains there. He was also an antagonist in Jimmy Neutron's Nicktoon Blast, a ride in Nickelodeon Studios Orlando, Florida. He was voiced by S. Scott Bullock in the television series, and Patrick Stewart in the movie.
