(A Little Joker Fact) The Joker is renowned as Batman's greatest enemy. While other villains rely on tried-and-true methods to commit crimes (such as Mr. Freeze's freeze gun or Poison Ivy's toxic plants), Joker has a variety of weapons at his disposal. For example, the flower he wears in his lapel sprays (at any given time) acid, poisonous laughing gas, or nothing at all. In Batman Beyond: Return of the Joker and much earlier in "Dreadful Birthday, Dear Joker!" (Batman #321), the Joker has a gun which at first shoots a flag saying "BANG!", but then, with another pull of the trigger, the flag fires and impales its target. His most recurring gadget is a high-voltage hand-buzzer, which he uses to electrocute his victims with a handshake.
