Disney Vs Non Disney Villains
Vs Prince John
Warren makes his first appearence when he is hired by Prince John to capture Robin Hood. Warren is able to complete this task; however, when he demands his pay, the greedy Prince John furiously yells at him and orders him to be arrested. Warren is taken to jail, where he meets a tall figure that helps him escape. Warren, aided by his massive band of cats, invades Prince John's castle. A large brawl takes place that ends with Warren burning John's castle down and Prince John escaping. Warren ultimately steals all of John's money, and the tall figure that helped Warren escape, Pete, becomes the new king.
After making a name for himself as a big time criminal, Warren threatens the criminal empire of Professor Ratigan, giving the rat a small amount of time to leave the city before he runs him out of town. The following evening, Ratigan opposes Warren himself and presents his secret weapon, the Giant Mouse of Minsk. The terrifying machine is enough to chase Warren and his gang out of the city and apparently go into hiding.
