LeQuack is the minor antagonist. He is a French con artist duck that has a fake amnesia-specialist license, and comes to their house when Muriel suffers from amnesia. Since then, he frequently returns and manages to coerce the Bagges into helping him commit crime sprees. He is always arrested by the end of the episode, but manages to escape, often shown leaving a scene of destruction with implied casualties of his captors, stating, "You have not seen the last of LeQuack."
