William Bletcher was an American actor. He was known for voice roles for various classic animated characters, most notably Pete in Walt Disney's Mickey Mouse short films and the Big Bad Wolf in Disney's Three Little Pigs.

Pete is a cartoon character created by Walt Disney and Ub Iwerks of The Walt Disney Company. Pete is traditionally depicted as the villainous arch-nemesis of Mickey Mouse, and was made notorious for his repeated attempts to kidnap Minnie Mouse. Pete is the oldest continuing Disney character, having debuted in the cartoon Alice Solves the Puzzle in 1925. He originally bore the appearance of an anthropomorphic bear, but with the advent of Mickey in 1928, he was defined as a cat.
