Corky James "Jimbo" Jones Sr., also known as Jamesbo, Dr. J, and Hector Gutierrez, is one of the bullies at Springfield Elementary. Jimbo wears a purple knit cap (originally no knit cap), a black short-sleeved T-shirt, emblazoned with a menacing skull (originally, a yellow short-sleeved dress shirt), blue jeans, and black shoes. Bart describes him as a good looking rebel who plays by his own rules.
Kearney Zzyzwicz: He appears to be the ugliest and toughest of the bullies but is quite the opposite, and is very easily distracted.
Dolph Starbeam: Dolph is recognized by his asymmetrical haircut, which covers one eye. He wears cutoff shorts and Chuck Taylor All-Stars style basketball shoes. Dolph is 13 years old. He is also left-handed. Dolph's hair can appear either reddish (like Jimbo's) or dark brown.
