Bedlam (Jesse Aaronson) is a mutant superhero appearing in American comic books published by Marvel Comics. He originally possessed the mutant ability to create and project a bio-EM field. This has the effect of temporarily disabling any similarly powered technology in the vicinity. He can also utilize his power to scan the environment for other pre-existing energy fields. After the High Evolutionary reset the mutant genome in every mutant on the planet, Jesse's abilities expanded to be able to affect the human brain's neural chemistry, thus allowing him to project the illusion of pain and confusion into other people.
The character made his live-action cinematic debut in the film Deadpool 2, portrayed by Terry Crews.
