Mickey Mouse
Created as a replacement for a prior Disney character, Oswald the Lucky Rabbit, Mickey first appeared in the short "Plane Crazy", debuting publicly in the short film "Steamboat Willie" (1928), one of the first sound cartoons. He went on to appear in over 130 films, including "The Band Concert" (1935), "Brave Little Tailor" (1938), and "Fantasia" (1940). Mickey appeared primarily in short films, but also occasionally in feature-length films. Ten of Mickey's cartoons were nominated for the Academy Award for Best Animated Short Film, one of which, "Lend a Paw", won the award in 1942. In 1978, Mickey became the first cartoon character to have a star on the Hollywood Walk of Fame.
Mighty Mouse
The first seven films starred the character named Super Mouse. In these early films, the character's costume is much closer in design to that of Superman (blue tunic and tights with red trunks and cape). In certain subsequent television airings, the words "Super Mouse" were edited out, and the words "Mighty Mouse" were dubbed in its place.
