Edgar Balthazar

Edgar was the main villain of the Disney movie Aristocats: although he started of as the butler of Dutchess's owner he quickly turned treacherous when he overheard her plan to leave her fortune to Dutchess and the kittens - prompting Edgar to come up with a plan to get rid of them and inherit the wealth for himself.

Edgar was very sneaky and managed to get away with his crime without Dutchess's owner noticing yet when they managed to return he was forced to come up with a second plan: namely to ship them off to Timbuckto, however he was defeated by the heroic tomcats and ended up shipped off to Timbuckto himself when he fell into the crate during a final battle.
