Nathan is the secondary antagonist in the direct-to-video film Alvin and the Chipmunks Meet the Wolfman. He is a tall, muscular bully with a yellow mohawk. The primary victim of his attacks is Theodore. Theodore is frequently bossed around and even forced to have Dave make his lunch for Nathan's liking. Nathan is nearly chosen for the replacement lead in the school's play but Principal Milliken chooses Theodore instead. By the end of the film Nathan no longer bullies Theodore and are seen in a conga line together.
