Black Pete is one of the earlier versions of Pete.
Black Pete proceeded the Pete that appeared in Oswald the Lucky Rabbit cartoons and has, by this time, shed his bear-like appearance, and had become more defined as a cat. Black Pete appeared in only a few cartoons in 1928; one of the only two being; The Gallopin' Gaucho and Steamboat Willie. Black Pete, however, was soon replaced by Peg Leg Pete (or Big Bad Pete) and recognized as more a "fatter" cat. Peg Leg Pete was then replaced (and later on seen to Wasteland) by the current/modern Pete.
