Anthrax
There’s a reason that when the world’s most insane military supervillains went looking for a disease they could turn into a weapon, they settled on anthrax. It’s fast, lethal, and you can get anthrax just by touching something that has touched something that had anthrax spores on it in a sort of Six Degrees of Separation of Death.
Initial symptoms of inhalation anthrax are, you guessed it, just like the flu. Except for the part where you die, which shouldn’t take longer than a few days. Play us out, obligatory Scott Ian reference:
“The horror of it all
The horror of it all
The horror of it all
The horror of it all
Say goodbye; it’s such a horror
My memories; there’s nothing harder
Anger and hatred fill the page
So smash the walls—it’s time to rage.”
