James Isaac "Jimmy" Neutron is the titular main protagonist of the Jimmy Neutron franchise. He is named after the scientists James Isaac Newton, and James Chadwick, who was nicknamed "Jimmy Neutron" because of his very first discovery of the neutron.
Jimmy is a young genius inventor, but his inventions seem to cause more destruction than anything and it is usually up to him to stop them. He lives in Retroville with his robot dog, Goddard, and his parents Hugh, a bumbling car salesman and duck-lover, and Judy Neutron. His best friends are: dim-witted and overweight Carl Wheezer, robot dog Goddard, his on and off girlfriend Cindy Vortex, hyperactive Ultra-Lord loving Sheen Estevez, sensible and music loving Libby Folfax, and cool and suave Nick Dean, all of whom he usually takes on adventures and crazy expeditions and serve as a perfect foil to Jimmy's brilliance.
