King Goobot V is the main antagonist of Jimmy Neutron: Boy Genius and a minor antagonist in The Adventures of Jimmy Neutron: Boy Genius. He is Jimmy's arch-nemesis, Ooblar's older brother, leader, and boss, and the supreme ruler of the Yokians.
- Goobot is similar to Lex Luthor from the Superman comics.
- He is also similar to Dr. Eggman from the Sonic the Hedgehog franchise, much to that of his personality.
- Goobot is also the main antagonist of Jimmy Neutron's Nicktoon Blast.
- Originally, Goobot was designed as a tall, slim alien and not wearing a golden unicorn. Instead, he wore a grey metal suit, as well as a different-colored crown.
- It is possible that Goobot is still in the Late Cretaceous period 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 asking Jimmy which alien could have sent the Alien Rock.
- Goobot made a cameo appearance in the beginning of "Jimmy Timmy Power Hour 3: The Jerkinators" when Jimmy was looking at what everyone was doing.
