King Goobot V is a villain in the Jimmy Neutron franchise. He is Jimmy's arch-nemesis, Ooblar's older brother, leader, and former boss, and the supreme ruler of the Yolkians.

After seeing Jimmy's message from Earth, he captured all the adults so they'd be fed to their evil chicken god, Poultra. When Jimmy and his friends arrived on Yokus, he threw them into a prison, so they'd be imprisoned until they were adults to be Poultra's next human sacrifice, which makes him a sadist as well. Luckily, Jimmy stopped his evil plan and saved all of the adults. 

Goobot and his minons returned in The Eggpire Strikes Back, where he and the Yolkians pretend to have changed due to Poultra's death. Goobot's plan was to have Jimmy's friends and family lost their trust in them and then have Jimmy watch Poultra devour everyone he cared about. 

Finally, he appears in The League of Villains where he gathers several of Jimmy's enemies to finally kill him. With the help of his friends and the reformed Space Bandits, Jimmy trapped Goobot and his minons in prehistory forever. It is unknown what happened to Goobot and the villains after that, but they were probably killed by the dinosaurs. 


  • Goobot is similar to Lex Luthor from the Superman franchise.
  • Goobot is also the main antagonist of Jimmy Neutron's Nicktoon Blast.
  • In the pilot, he wore a grey metal suit, as well as a different-colored crown.
  • Goobot is still in prehistory (along with the other villains), due to Jimmy's opinion, which is that Goobot is millions of years ahead of everyone.
  • He was mentioned in "Win, Lose and Kaboom" when Cindy was warning Jimmy about the possible dangers of answering the space rock. 
  • Even though Calamitous is the main villain, Goobot is more remembered by fans. 
  • He likes being called "Big Poppa".
