 He and Cindy Vortex have a dislike for each other, although it is revealed in later episodes that they secretly love each other.Neutron is usually seen wearing a red T-shirt with his yellow trademark atom symbol on it, blue jeans, and white Chuck-Taylor Converse All-Star sneakers, but blue shorts and brown shoes in the film.He has blue eyes and a huge mass of brown hair that is considered "anti-gravity" and is in a whipped-up form, earning him many nicknames from classmates (especially Cindy), such as "Whippy-Dip" from his clone Evil Jimmy, and "Señor Fudge-Head" and "Buzz Adams" (from Cosmo in "The Jimmy Timmy Power Hour").
