Chief McBrusque is the tertiary antagonist of An American Tail: The Treasure of Manhattan Island. He is a ferocious, and overweight chief of the NYPD (New York City Police Department), and a very strict and harsh chief. He enjoys beating and causing trouble to the other mice of New York, particularly the immigrants, seeing them as trouble-makers. He, like the factory owners are suspicious of Papa and see 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. McBrusque taunts Fievel with the torch, only to be defeated by Fievel as he bites McBrusque in the arm and jumps on his foot. Fievel grabs the torch and throws it at the gunpowder, causing an explosion and the tunnel to be sealed. McBrusque and Scuttlebutt tries to escape, but they're too late as he and Scuttlebutt fall in the river and drown. He has never been heard of ever since.
He and Scuttlebutt are the only villains in the American Tail series to be killed off.
Despite being a secondary antagonist, Chief McBrusque is one of the most evil villains in the American Tail film series (alongside Warren T. Rat) because of his cruelty to the workers and others.
