Emmett McKinley is a muscular and durable student known for punching dents and holes into the school's steel lockers. He is known for his "massive fists", which he uses to destroy objects and hurt people. Emmett is extremely stupid, and has been held back at least three times (and possibly more). He seldom speaks in comparison to the other 15th Graders. He acts as the muscle of the group, beating up anyone at anytime on Chopper's command.
