Buster is a 5th (later 6th) grade student of Third Street School and a friend of Lawson's. He is a jock and a bully, much like Lawson's other cronies. He is tall, sports spiky auburn hair and wears a blue shirt with two red stripes.
In the episode "Bad Hair Day," he was desperate to get the 'Mikey' haircut as he was going to his cousin's wedding, but did not actually get the haircut. He was the only one who didn't get it, apart from Spinelli and Gretchen who were absent from school.
He is seen in the episode "Wild Child" orchestrating a prank that back-fired and put T.J. and his "Pee Wee Pal" in hot water.
