Adam Fischer is the protege of Gary Smith and rival of Craig Harper
Adam started a little while before Craig and "befriended" Jimmy Hopkins and Pete Kowalski. Little did they know he was actually working with ex-student Gary Smith to retake Bullworth Academy. After Jimmy took a new student, Craig, under his wing, Adam revealed his true colors by betraying Jimmy, Craig and Pete.
