Fan Casting The Joker in The Batman (1990)

Jack Lawrence Napier, later known as the Joker, is the secondary antagonist of The Batman. He is the sadistic enforcer for Hugo Strange (who encouraged him as a child to become even more violent and sadistic as an adult), as well as one of the most sociopathic and dangerous criminal masterminds to ever live, earning the nickname "Jack the Ripper." After an encounter with Batman at the Axis Chemical Plant, which ended with him being accidentally dropped into a vat of chemicals, permanently leaving him with bone-white skin, ruby-red lips and green hair, he becomes the psychotic supervillain known as the Joker, seeking revenge against Batman for what he did to him, while also lusting after Silver St. Cloud.
