Fictional chemical weapons (need some)

…well, not that kind of “need,” but I’m looking for some examples for a pet project. Anything not mentioned on the list of fictional chemical weapons already, and especially anything with it’s own made up chemical weapon designation.

So far, I’ve got DDID—which, according to Tim Burton, is the basis for Joker venom.

Anyone else want to join in the creepy trivia?

Would biological weapons work, too? Asimov’s Pebble in the Sky involves a weaponized radioactive version of the common cold, to which native Earthers are all immune, but which would kill everyone else in the Galaxy.

What sort of chemical weapons are you looking for? Anti-materiel, anti-personnel, utility or all three?

Anti-personnel, primarily, though the others are worth at least a nod. But anything with a given name or code designation, specifically. So “the unnamed nerve gas used by Doctor Khaotica”* isn’t useful for my purposes, but if it was called “Khatoicol” or “VK,” it’s just gravy.
*The star of the classic 1954 movie serial, Doctor Khaotica and the Stock Footage Attack, of course.

Lois McMaster Bujold Vorkosigan series
Soltoxin - chemical warfare agent, causes the lungs to dissolve.The antidote to it is a teratogen causing bone dissolution.

Unnamed Haut toxin - dissolves the bones and organs into goop via nanobots

Fetaine, also from the Vorkosigan books; a terror weapon that scrambles the DNA in the gonads of anyone exposed. Designed to create massive amount of birth defects.

Black Smoke, from *The War of the Worlds.

You need, of course, the Nude Bomb!

The Catalyst from The Secret of the Sinister Six; a gas that erases ink. Such as the ink on money, legal documents, and so forth; an economic weapon.
Algotoxin from IIRC Brightness Falls From the Air; a poison that causes intense pain. What makes it awful is that the pain is permanent.

Spasm: From the Matador series; it locks people immobile for six months. Delivered by dart.

Man that was awful. :smack: Last drive in movie I saw.

Upsidasium!

Ice nine and tiberium can both be used as weapons.

Alkahest from The Case of the Toxic Spell Dump; it’s the Universal Solvent of alchemy fame and as the term implies dissolves anything and everything. Eventually burning to the center of the Earth.

Remembered one from a book I just read: Grey #3, from Terry Pratchett’s The Amazing Maurice and his Educated Rodents, a Rats of NIMH-style tale of intelligent rats. The rats have a professional interest in a variety of poisons humans use on them, of which Grey #3 is the nastiest. It has no known antidote (and the rats are very good at finding antidotes even when humans can’t), no chance of natural survival, and melts your digestive tract from the inside out in about 20 minutes after exposure.
