For some reason (you choose, magic, science, whatever) Foggy finds himself in an alternative universe where he was never born. Not that big of a deal, right? Everything is the same, except without being a moral compass and best friend to Matt, the Devil has become more of a devil, to a point where Matt is killing and torturing people just to get what he needs.

Then, of course, Foggy meets this Devil and calls him "Matt". Ensue aftermath.
