Jimmy Neutron

This article is about the fictional character. For other uses, see Jimmy Neutron (disambiguation).

Jimmy Neutron (voiced by Debi Derryberry) is a fictional character in the TV series The Adventures of Jimmy Neutron: Boy Genius and the movie Jimmy Neutron: Boy Genius. He lives in Retroville with his robotic dog, Goddard (named after Robert H. Goddard, a pioneer in modern rocketry), his father, bumbling duck-lover Hugh and his mother, neat freak Judy Neutron.

Jimmy's full name is James Isaac Neutron, but only his mother calls him that. His father calls him "Jimbo" and Cindy Vortex, an extraordinarily intelligent girl from Jimmy's class (who is secretly in love with him), often refers to him as Nerdtron, Spewtron, King Cranium and other such names. Cindy's best friend is Libby, while Jimmy has two best friends, Carl Wheezer and Sheen Estevez.

He has a huge IQ (210), however he is not always very smart and, no matter how noble his intentions, almost all of his inventions lead to mishaps. One of his most captivating features is the fact that his cranium projects farther than normal in order to house his large brain, something which almost everyone comments on--particularly Cindy. Whenever he needs to come up with an idea, he will urge his brain on, saying "Think, think, think!", whereafter there will be a short clip that shows Jimmy's brain and an image of a scene that happened earlier in the episode. Then Jimmy will shout, "Brain Blast!", and then give the solution that saves the day.

His birthday is March 14th - PI Day.
