Truck, no real name known, is a brick and a bully. He runs with two other kids, Tee-Kay and Nitro, who call themselves TNT. Like the others, he's not too bright, a virulent gay-basher and a pathological liar about who started a fight.
He's at the Halloween dance during the Syndicate attack.
He and his buddies attack Reach twice, once on their own, once by the connivance of the evil mastermind, and then Nephandus tries to get them to do it a third time. He's moved from Twain to Melville after the second incident.
