Buster is "the king of sportsmanship" for the Carmichaels. Buster, his siblings, and his parents all make their debut in Meet the Carmichaels, in which their family move into the neighborhood. Like his older sister Alisa, Susie admires Buster for his bravery. He is a typical 10-year-old boy, very active, loves games, and is often playing sports. He likes to play with Susie when he can, but he has a habit of trying to be dominating. He often fights with his older sister Alisa, who can be seen in The Last Babysitter as they butt heads for dominance. The character is very competitive when it comes to fighting with Alisa, and he once decides to play a prank for her sending his friend Sticky home. However, because of Susie and Tommy's interference, his prank fails and Alisa sends him to bed.
