Bull Sharkowski

The school's bully, Virgil "Bull" Sharkowski is an African-American bull shark who enjoys beating up smaller kids and stealing their lunches. His intimidating presence, however, is offset by a high-pitched, squeaky voice (sounding like Mike Tyson) that sometimes lessens the impact of his verbal threats. Despite being a bully, he also has a soft humane side that he doesn't usually realize he's revealing. Due to Bull being a water creature, he wears water-filled headphones over his gills to help him breathe; when he talks, he'll stop as his gills suck up the water with a loud noise. His nickname is a mildly obscure reference to the fact that bull sharks are known to be the most aggressive of all shark species.
