Citizens of Yolkus! I, King Goobot V, give you...SACRIFICE!
~ Goobot announcing the parental sacrifice and summoning of Poultra.

King Goobot V, better known simply as King Goobot or Goobot, is the main antagonist of Nickelodeon's 6th feature film Jimmy Neutron: Boy Genius, and a major antagonist in its TV series, The Adventures of Jimmy Neutron: Boy Genius. He is Jimmy's archenemy, Ooblar's older brother, the employer of the Yokian Fleet Commander and the tyrannical king of Yokus.

In the film, he was voiced by Patrick Stewart, who also played Pharaoh Seti I in DreamWorks' The Prince of Egypt, Professor Xavier in the X-Men films, Avery Bullock in American Dad, and King Buffo in the Courage the Cowardly Dog series. In the television series, he was voiced by S. Scott Bullock.


In the film, King Goobot kidnaps all of the children's parents from Retroville, and tries to feed them to Poultra, a humongous alien chicken whom he and his people worshiped for centuries. He was aided by his majordomo, Ooblar and although he tried to off Jimmy and his friends after they rescued their parents, Jimmy grew to a huge size and defeated him.

In the TV series, King Goobot arrives on Earth and pretends to be nice to the citizens and even invite the citizens to the party (which is actually a trap), but Jimmy suspects something about Goobot's scheme before Goobot bans him from the party as the citizens believe that Jimmy is a big jerk to the Yolkians. Later, he steals one of Jimmy's inventions to revive Poultra and traps the citizens as he tries to feed them to Poultra, but Jimmy puts some Purple Flurp in Poultra's water bowl and Poultra explodes after burping. Goobot then goes back into space in a giant eggshell spaceship along with the other yokians and Ooblar before the citizens apologize to Jimmy for not listening to him earlier and praise him as a hero.

King Goobot is 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 remained there.


King Goobot is portrayed as greedy, deceiving and authoritative. He is the tyrannical, arrogant, manipulative and self-centered king of Yokus. He is very power-hungry and dictatorial oppressor who can control over his warriors and his space armada. One of his most malevolent and duplicitous plans is when he theoretically tries to destroy Retroville.


You see, Jimmy. you can't win. All of your friends and family would be safe at home. If it wasn't for one little problem. You! (Jimmy Neutron: Little?) Now you all must die! (Laughing)
