He is a clone of Crazy Dave from the past, present, and future. He always bothers Crazy Dave in his mind. He is said to be a racist, and made to random races. The races are Dem & Hemion. As he said it, Hemions are good while Dems are like Jews. Even the villain Cone Head was blown away at the fact he is racist, and is not happy about it. While Cone Head was trying to talk he randomly interrupted and said if he can have an n word pass.
He also tries to ruin Crazy Dave's life anyway possible. One time when he went to do something, Future Dave showed up and started trolling everyone. He does have 2 arms but it's shown that he only has one when he trolled, perhaps so he could hint that he is indeed a clone but not make it too obvious.
