Fan Casting The Joker in My DCEU

The Joker is a serial killer and a super-villain, a dangerous madman who dresses like a clown. He is often recognized as Batman's greatest enemy, living in and terrorizing Gotham City, although he spends most of his time in Arkham Asylum. In addition to being a deadly and unpredictable physical combatant, he is a brilliant and ruthless criminal mastermind. His crimes require no motivation other than his sadistic desire to show people the meaninglessness of life through pain and death. Batman is his only worthy opponent, and although he has passed up multiple opportunities to murder the dark knight, he has no such problems with killing Robin or crippling Batgirl.
