Jimmy! Jim-Jim-Bo-Baby!
Jimmy "Jimbo" Neutron is a 10-year-old genius and the titular main protagonist of the Jimmy Neutron franchise. He has fair skin, a disproportionately large forehead, blue eyes, and brown hair in a swirly cowlick. He is often teased because he is shorter than most boys of his age, though sometimes he appears to be the same height as his friends. Jimmy's wardrobe consists almost exclusively of red T-shirts that sport his trademark symbol of a yellow atom.
His father once sat on a banana and it changed his life.
