Time case

The Malevolent Counterintuitive Pathogen may or may not be a thing in the IDW portion of the Generation 1 continuity family

The Uncertainty Principle states that certain physical properties cannot be known at the same time as one another. Brainstorm weaponized this curiosity of quantum mechanics in the latest of his Unmentionables concocted at the Kimia Facility, the Malevolent Counterintuitive Pathogen. According to Brainstorm, the Malevolent Counterintuitive Pathogen is tightly contained inside a special case. Anyone who opens the case will find the thing they least expect to see. And then it kills them.

...Unless he was just screwing with Ironfist and Skyfall. Heh heh...heh?

Fiction

IDW Generation 1 continuity

Brainstorm was on his way into Room 113 to plead another case for his Unmentionables before the Ethics Committee when he passed Ironfist and Skyfall on their way out. When they asked about the sturdy case handcuffed to his wrist, Brainstorm gleefully laid out the details of the Malevolent Counterintuitive Pathogen for them. Skyfall dragged Ironfist off to the Exit Rooms before he could find out whether Brainstorm was joking. Bullets

When he joined the Lost Light, Brainstorm took a certain sturdy briefcase with him and claimed that if opened outside of a controlled environment, it'd be "end of the world".

Later, Chromedome claimed he'd heard that Brainstorm opened the briefcase on Hydrus 4 and "the sun went out", to which Brainstorm replied that was a filthy stinking lie. It was actually Hydrus 5. Rules of Disengagement
