The Joker's Weapons

The Joker utilises a wide variety of weapons and gadgets, most of which are disguised as harmless practical joke items.

Razor-sharp playing cards
The Joker's playing cards are used much like shuriken - he can throw them with astounding accuracy, and they have been shown to be sharp enough to damage Batman's gliding harness.

Joy buzzer
The joy buzzer is one of the Joker's most prominent weapons - worn on the hand as a ring, it discharges a lethal electric current into anything that comes into contact. Whilst it has been used for assassinations by tricking the victim into shaking hands, it is also used as a hand-to-hand weapon and can even be used as a battery for powering machinery.

Harpoon gun
The Joker's harpoon gun initially takes the appearence of a harmless toy gun that shoots a small flag reading "BANG!". However, after a second pull of the trigger, the flag blasts out of the barrel and impales the target. Notably, in Batman Beyond: Return of the Joker, the harpoon gun was used by Tim Drake to kill the Joker.

Squirting flower
The flower that the Joker wears on his lapel can squirt a wide variety of chemicals. The chemical in the flower depends on the Joker's mood - it can be poison, Joker venom, acid, water or even nothing at all.

Boxing glove arm
In some incarnations the Joker has been shown to possess an extending mechanical arm with a boxing glove on the end. Whilst it appears to be harmless, the force of the arm is shown to be extremely powerful - enough to knock people out.
