Rancid Rabbit is one of the main antagonists of CatDog. He is a rather mean rabbit who craves money and power more than anything considering the majority of his jobs involves him being at a higher position of power (such as the manager of a taco restaurant or even being the president). He often shows his greedy side whenever he has a chance to swindle CatDog or others out of money for something expensive (such as taking a television set CatDog recently won in a pie eating contest as payment for not affording his doctor bill. He is voiced by Billy West.
