However, he is very intelligent, constructing his own working robot to win a science competition. He dates Wayne's cousin Jessica towards the end of the first season. He becomes Ace's secondary sidekick in the second season, wears glasses, and works as a delivery boy for Rick Hummel. Chuck provides his computer technical skills and knowledge of the game to upgrade Ace and Sparx.
