He enjoys beating and causing trouble to the other mice of New York. He, like the factory owners, is suspicious of Papa and sees him as a trouble-maker. When he followed Fievel and the others to the underground cave there was a battle between the Indians and the police. Eventually the police surrendered and were believed to have left. Then as Fievel was about to set the gun powder, McBrusque and Scuttlebutt returned for round two only to drown in the river after Fievel set the gun powder. He has never been heard of ever since.
- He and Scuttlebutt are presumably the only villains in the American Tail series to die.
- He was voiced by Sherman Howard, who also voiced Derek Powers in Batman Beyond.
- Despite being a tertiary antagonist, Chief McBrusque is one of the most evil villains in the American Tail film series (alongside Warren T.) because of his cruelty to the workers and others.
