Rancid Rabbit

Rancid Rabbit is the semi-antagonist of the Nickelodeon animated series CatDog. He is the stereotypical authority figure and is one of the show's main antagonists right next to The Greaser Dogs. He has multiple jobs which includes police officer, lifeguard, prison guard, boss of various businesses, principal, president, mayor, Egyptian Pharaoh, doctor, TV host, contest judge, Taco Depot Manager, store manager, etc. Rancid really hates CatDog and would get out of his way to punish them or force them to work for him.

At one point in the series, he at first started arresting dogs for not having licenses, but soon arrests everyone else in town for not having one (except for Cat who got his license years prior). After everyone breaks out, they ganged up on Rancid and put him in prison.
