History
The history of this version of the Invisible Woman is presumably similar to that of her mainstream counterparts with the biggest difference being the absence of a Sliding Timescale.
Sue Storm left her husband, Reed Richards, and went to be with Prince Namor.[1]
Sue was one of the few superhumans who were not teleported off of Earth to participate in the Secret Wars, and as such was among the small handful that attempted to prevent Soviet-launched nuclear missiles from striking the United States.[2]
What became of Sue later is unknown. She was likely one of the many superheroes who were left "dead or missing" following Doctor Doom's takeover of the planet, though it's possible she was safe from Doom while in Atlantis.[3]
