Steve is Peter's best friend. He works at a pizza shop Peter likes this for he loves pizza. Steve does not seem as interested in sports as Peter. He does seem to like to eat, but not nearly as much a Peter.
He is impressed when Peter has punched Mike Barnes in the nose because he (Steve) has been wanting to deck him for years, and he still enjoys it even when Peter says it was stupid. He is regularly shown wearing a red/white T-shirt and blue jeans.
He (like Peter) is also depicted as having an exaggerated appetite.
Steve also holds other stereotypical interests for an adolescent male, including swimsuit models, video games, and guitar playing. He once wanted to invite all the cheerleaders to the party.
