He made his first appearance in "Eek, A Penis!", when Mitch Murphy made a sketch of him with a large erection. He later physically appeared in the uncut DVD movie version of "Imaginationland", being attacked and killed by the evil imaginary characters. During "The Ring", his main motive with the Jonas Brothers was to "sell sex" to little girls with sex euphemisms to "stupid" Christian families.
At the end of the episode, Mickey is shown to have the ability to grow in size, breathe fire, and fly. His hovering over the city mimics the Mickey Mouse balloon seen in the Macy's Thanksgiving Day Parade. It is implied that Mickey might be of some sort of divine origin. A news reporter commenting on Mickey's onslaught mentions that Mickey would afterwards return to Valhalla, of Norse mythology, where he would then slumber and feed.
Mickey was seen again in "200" and "201" with the celebrities who were suing South Park; he had a speaking part in "201" where he is one of the many celebrities and gingers arguing who go into the goo machine and later on fights against the Super Best Friends.
Mickey reappears in "Obama Wins!" and is still in control of the Disney Corporation. Thrilled at the acquisition of the Star Wars franchise, he schemes with Eric Cartman to get Mitt Romney elected President of the United States.
Mickey is a black mouse with a tan area near his eyes as well as his snout area. He wears a white "dress" shirt, red tie, pink, gold-buttoned shorts, white gloves, and large, brown shoes.
Although he is portrayed as a good character in "Imaginationland", he changes sides in "The Ring". In this episode, Mickey is given a more prominent role, where he is seen as the owner of the Disney Company and boss to the Jonas Brothers. Mickey is portrayed as an evil money-hungry, foul-mouthed corporate mogul who is both verbally and physically abusive to his employees. For example, when Joe Jonas states that he would quit, Mickey punches Joe in the balls, and begins kicking his face, then forcing him to get up. It should be noted that Mickey says his trademark "Ha-ha!" laugh at the end of most of his sentences, which in context, comes off like a nervous tic. Also, Mickey appears to be insane threatening to kill Stan Marsh, Kyle Broflovski, Eric Cartman and Jonas Brothers with a chainsaw in order to prevent them from ruining his concert.
