Midnight Oil
A gas developed by Howard Stark and rated among the most dangerous things he ever built.
The Midnight Oil is a gas Howard Stark developed and then classified among the most dangerous things he ever made. It began as a combat drug, something to keep soldiers awake and working well past the point a person should be. What it actually does is hand them every symptom of extreme sleep deprivation at once, anger and hallucination and psychosis together, until whoever breathes it attacks anyone within reach without knowing who they are. It goes after the throat as well, and the damage it does to the larynx can be permanent.
