Peter "Peg Leg" Pete is a character from the Walt Disney Company studios. He is a cat who is sometimes depicted with a peg leg. He is mostly known as the arch-nemesis of Mickey Mouse. Though usually associated with the Mickey Mouse universe, Pete appeared in Disney's animated cartoon series Alice Comedies before the first appearance of Mickey Mouse, and is Disney's oldest continuing character. Pete is one of the only two official Disney Villains members from classic cartoons instead of movies, the other being The Big Bad Wolf.
Pete first appeared in the 1925 Alice comedy, Alice Solves the Puzzle, as Bootleg Pete, the name referencing to his career of bootlegging alcoholic beverages during the United States Prohibition. In this short, Pete antagonizes Alice.
Pete later appeared in an Oswald the Lucky Rabbit cartoons, when Walt Disney needed a villain to stack up against his character, Oswald. However, Pete first appears in a Mickey Mouse cartoon when they first came out in 1928, and is best known as Mickey Mouse's archenemy, beginning with the cartoons The Gallopin' Gaucho and Steamboat Willie. He has, by this time, shed his bear-like appearance, and had become more defined as a cat. In some instances, Pete had shown romantic feelings towards Minnie, which would lead to him kidnapping her and Mickey having to rescue her. This formula would become famous both inside and outside the Disney universe.
In the Disney cartoons of the 1930s, Pete would be Mickey Mouse's nemesis, but would vary in professions, from an all-out outlaw (Gallopin' Gaucho) to a brutal law-enforcer (such as Moving Day, in which he is a sheriff who serves Mickey and Donald Duck with an eviction notice). Pete has since been the nemesis in most Mickey and Friends productions.
