Fun and Fancy Free
Disney had provided the voice for Mickey Mouse since his debut in 1928, and "Fun and Fancy Free" was the last time he would voice the role regularly, as he no longer had the time or energy to do so. Disney recorded most of Mickey's dialogue in the spring and summer of 1941. Sound effects artist Jimmy MacDonald would become the character's new voice actor, starting in 1948. Disney, however, did reprise the role for the introduction to the original 1955–59 run of "The Mickey Mouse Club".
Robert Armstrong (comics)
Mickey Rat (an obvious parody of Mickey Mouse) was created by Armstrong in 1971 as a character on a T-shirt. The popularity of the character led to him appearing in comics, which were initially scripted by Chester C. Crill. Mickey's first appearance was "L.A. Comics" #1 (published by the Los Angeles Comic Book Company in December 1971). Mickey was "sleazy, opportunistic, capable of just about any foul deed, but also shallow, one-dimensional, and incapable of growth or subtlety. He seems to have had little in the way of motivation, beyond his creators' desire to make him the opposite of the other Mickey in every possible way."
