Corey is a computer geek and was on Percy's team in dodgeball. It appears that he is often on Percy's team, as all of the jocks go to Matt's side. He hides behind the wall mat, but when a Laistrygoinian threw a Flaming Dodgeball, he gets hit. Percy shows that Corey is a close friend by yelling in fear he got hurt, while Tyson pulls him out right before the dodgeball hits. It is presumed he escaped with the other students when Percy broke the doors open, and that he too was manipulated by the Mist and forgot what had happened.
