Canon Bio
Pete (also known by variations of his name, including Peg-Leg Pete, Black Pete, Big Pete, Bad Pete, Big Bad Pete, Mighty Pete, Bootleg Pete, Mr. Peter Pete, Pete the Cat, Sneaky Pete, and Poncey Pete) is a cartoon character from the Walt Disney Company studios. He is an anthropamorphic cat (since 1928; earlier drawn as a bear) and is sometimes depicted with a peg leg, and generally depicted as the archenemy or rival of Mickey Mouse, Donald Duck, and Goofy. Though usually associated with the Mickey Mouse universe, Pete appeared in Disney's animated cartoon series Alice Comedies. He is Disney's oldest continuing character, appearing two years before Oswald the Lucky Rabbit (1927), and a full three years before Mickey Mouse (1928). Though Pete is officially a cat, his feline appearance was later subdued. In the TV series Goof Troop, he somewhat resembled a dog like many other characters in the series. Despite being an antagonist in most productions, he is sometimes depicted in a lighter tone making him a minor protagonist or neutral character. He is also shown to be Goofy's best friend or confidante as seen in Goof Troop as well as the film adaptation A Goofy Movie, and its sequel. When not directly the bad guy Pete is often the victim of either Goofy's mishaps and clumsiness, Mickey's mischief, or Donald's temper resulting in etheir the destruction of his property or great injury.
