Michael Joseph Jackson was an American singer who made his first appearance in 'The Jeffersons', where he was referred to as Michael Jefferson. After his death in 2009, he made three more appearances: in 'Dead Celebrities', which mainly focuses on his and other celebrities' deaths; in '200', where he is seen among the crowd of celebrities suing South Park; and in '#REHASH', as a hologram. Michael Jackson also appears as a boss in the South Park: The Fractured But Whole DLC From Dusk till Casa Bonita under the name 'Corey Haim'. Though talented, he is extremely childish, irresponsible, and delusional, playing with various children's toys, living in a fantasy world as well as neglecting his parental responsibilities in 'The Jeffersons'. He also saw no problem with sleeping in the same bed as young children that were not his children, despite the obvious inappropriate nature of such a situation. He also refused to accept his death in 'Dead Celebrities', even going as far as to possess Ike Broflovski in order to participate in a little girls' talent show. (Source: Fandom.com, CC BY-SA)
