The Joker was portrayed by Roger Stoneburner in the TV series Birds of Prey .Contents [show] BiographyEditPossibly the man who became the Joker fell in a vat of drainage chemicals because of Batman and became the Clown Prince of Crime. He and Batman had a long rivalry but Joker never managed to defeat the Dark Knight. Sometime later during one of his many inprisonments in Arkham Asylum psychiatrist, Dr. Harleen Quinzel attempted to cure Joker of his unique case of insanity though only found herself caught in Joker's web of lies and he manipulated her transformation into Harley Quinn. The Joker and Batman had a secret night war in New Gotham for many long years and one night Batman managed to finally defeated him and The Joker was taken into police custody since it became obvious that he would easily escape Arkham. With all of his criminal operations in Gotham cut off, Joker sought revenge against the Dark Knight. He then escaped the police's custody yet again and hired Clayface to kill Selina Kyle and Joker himself shot Batgirl at her apartment in his lust for revenge. Joker was later incarcerated in a maximum prison far away from New Gotham in order to keep New Gotham safe from his mad carnage. Although he was never seen in New Gotham again he left a horrific legacy that went as far as motivating his former accomplice and court jester, Harley Quinn to take over New Gotham to honour her captured love. It remains unclear what happened to The Joker afterwards although it is apparent that he never got the opportunity to terrorize Gotham again.Behind the scenesEditMark Hamill voiced the character but Roger Stoneburner played him (Mark Hamill is the only one of the two actors who is credited). He was only seen briefly in a flashback knocking on Barbara's door and shooting her in the midsection, crippling her.
