Joker Venom
Joker Venom is a comic book concept that first appeared in Batman #1
Joker's favorite weapon. A chemical that makes its victims die laughing and left with a permanent grin on their faces.
The Joker is commonly associated with this toxin. It is possibly his favourite killing technique.
Creation
Even in Batman issue #1 the Joker had this strange technique of killing. In numerous occasions the Joker is able to create a similar acting toxin with simple materials found in a common house hold, but the poisons most commonly thought of as parts in it's recipe are: hydrogen cyanide and strychnodide.
Effects
There are two types of Joker Venom one is lethal and the other simply causes insanity.
Lethal:
Simply put, kills with a smile. In some cases, it also gives the victim the same facial appearance as the Joker, with white flesh and blood red lips.
Non-Lethal
After prolonged exposure to the non-fatal forms can cause permanent brain damage. Also, while under it's influence black humour will be hilarious to anyone even the grimmest of characters will cheer up as they see their friends burn.
Transportable
The Joker has placed this poison in his squirting flowers and joy-buzzers. It can also be passed through vents and as seen in Batman (1989) it can become airborne through giant parade balloons.
