Big Norm is Norm's inner half. While Norm is the quiet, small, and well behaved mime that he is supposed to be, Big Norm is loud and obnoxious. He is cocky, and despite his actions, he is very confident. For example, upon meeting Team Bandicoot and Team Cortex, he doubted their chances of beating him and Norm, which indeed he was wrong and complemented a well fought race against them on the track. Despite their arguments, he is shown to be very protective of Little Norm, referring to him as his "little buddy" and seeming to take on an almost older brotherly role.
