Rancid Rabbit is the stereotypical authority figure and is one of the main antagonists in the Nickelodeon cartoon series, CatDog right next to The Greaser Dogs. He is the ruthless mayor of Nearburg and CatDog's arch rival, 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. He even cons Cat into buying Mean Bob toys and ice skates.
Rancid Rabbit is voiced by Billy West.
- He's only Cat's rival in most episodes.
- He has a cousin named Rotten Rabbit.
- He was nearly noticed as the principal when Cat found him as a cop.
- Thanks to Rancid, there were later some more corrupted giants on Nick like Bruno Bullnerd (Chalkzone) and Lok (Tak and The Power of Juju).
- One of his few non-villainous roles in the series was when he played a doctor in Flea or Die, in which he helps CatDog deal with their flea problem without showing any signs of antagonism towards the duo.
