Fan Casting The Joker in Batman: The Mask of the Phantasm

A sadistic and delusional psychopath and Batman's archenemy. He was the first villain defeated by Batman when he was the Red Hood, leader of the gang that terrorized Gotham, and hunted Andrea's father until he fell into a vat of chemicals at Ace Chemicals. He also murdered Jason Todd, the second Robin and Bruce's protégé, a year ago, to try to prove that all it takes is one bad day to drive someone insane. Joker sees himself as the antithesis of Batman, the living manifestation of chaos while Batman is order.
