Joker bang gun

Joker with his BANG Gun.

The BANG Gun is a gun used by the Joker in the Batman Animated Universe.

The gun is a two stage weapon: one pull of the trigger produces a "Bang" flag as in a standard joke pistol, however a second trigger pull fires the flag as a lethal projectile, similar to a spear gun.

In Batman Beyond : Return of The Joker Joker used the gun to kill his underling Bonk, after Bonk began to speak out against him. In the uncut version of the film, the Joker himself was killed with the weapon by Joker Jr.
