James Isaac "Jimmy" Neutron (Born 21 December) is the main protagonist of the television series and the 2001 movie. He is the world's smartest ten-year-old. He is named after scientists Sir Isaac Newton, and James Chadwick who was nicknamed "Jimmy Neutron", because of his discovery of the neutron.

Jimmy is a genius inventor, but his inventions seem to cause more destruction than anything good, and it is usually up to him and his friends to stop them. He lives in Retroville with his robot dog, Goddard, who is named after Robert H. Goddard (a pioneer in modern rocketry) and his parents, Hugh Neutron, a bumbling used car salesman and duck-lover, and his caring housewife mom, Judy Neutron.

Nicktoons Unite!Edit

Jimmy appeared as on of the four playable characters in Nicktoons Unite! Jimmy had summoned the other three heroes to his lab to tell them about the villains travelling dimensions and wanting to take them over, because the heroes defeated them before he hopes they can do it again. Jimmy and his team went through all of their home-worlds and defeated the Syndicate. When they returned home Jimmy gave them all Neutron Recallers to summon them if there is trouble again. Jimmy gave Danny a copy of the Fenton Thermos and Timmy could lend his Hyper-Cube. As everyone was gone he shouted to Cindy to get out.

Ultimate Nickelodeon Brawl Stars XEdit

Jimmy appears as a playable character in Ultimate Nickelodeon Brawl Stars X. He is one of the three characters representing his franchise. He can be considered a duo character as Goddard fights along with him.


Gifted with a stunning IQ and a love for science, Jimmy Neutron is often tinkering around in his laboratory, constantly inventing new gadgets and gizmos. Sadly, these tend to do more harm than good in his fair city of Retroville, but luckily, Jimmy is far from incompetent, and can often be counted on to save the day, even if he's the cause of the trouble. He has a love-hate rivalry with Cindy Vortex, who has recently become the target of his affections, as much as he hates to admit it sometimes.

Jimmy refuses to believe in magic. As a genius, If he does, He believes he will lose all crediabilty

The Nicktoons often depend on his sage advice and ability to come up with life saving ideas under pressure. Alongside Danny, Spongebob and other Nicktoons, he has saved the day more times than anyone can count, but only time would tell with his most dangerous challenge yet if he can pull another of his patented Brain Blasts!
