- Warren T Rat

Warren T. is the main villain of the film An American Tail, Warren T. is really a cat in rat's clothing and the leader of the Mott Street Maulers, a gang of cats who terrorize the mice of New York City. He is accompanied nearly all the time by his accountant Digit, a small British cockroach.

He offers false friendship to Fievel when the two meet and offers to take him to his missing family - yet after gaining Fievel's trust he cruelly sells him to a sweatshop, when next they meet it is some time after Fievel managed to escape the sweat-shop: he sees Warren T for what he truly is, a cat, and is imprisoned by Warren T and his gang to stop him telling anyone, however Fievel is released by Tiger - a soft-hearted minion who doesn't share the usual anti-mice feelings most cats do in American Tail.

Warren T and his gang give chase to Fievel but are caught in a trap by the mice, who have had enough of being bullied and unleash a mechanical-mouse that proceeds to knock Warren T and his gang off the harbor and into the sea - Warren T was last seen hitching a ride on a boat heading for China along with his gang.
