Ian is a teenager in Greg's soccer/football team as the regular goalkeeper, despite being 16 years old. He only appeared in the online version. He once got caught driving to the game, which started a fight between Mr. Keith and other coaches. The other coaches also kept asking for his birth certificate which would delay the game. However before a game started, an coach caught Ian driving to the game.
