Marvel Universe

As for how he knew he was in the Marvel Universe, it was simple, he saw it in her future. The Avengers, Galactus, the Fantastic four, Thanos etc. They were all there so if he couldn't guess that he was in the Marvel Universe then he needed to kill himself.

However he also didn't exactly know much about the universe. He knew the bits and pieces he grabbed from his half-assed reading some of the comics,

From postings concerning it, he was a fan but he was too busy to get into the franchise well enough. However the few he knew should allow him to survive pretty easily.

Of course now coupled with his powers, he was guaranteed to survive no matter what but the Marvel Universe was still a place full of many dangers.

This ranged from the famous Thanos to the mostly unknown Dominion, He believed that survival was guaranteed but beating them was a whole different thing.

As for why he said that he hit the jackpot, that was simple. He had entered a universe where his power would be relevant. His reincarnation was random.

Meaning that he could have been reborn into a normal universe where the laws of physics didn't allow for superpowers. Of course his mother box like physiology would grant him superpowers still but what use would they be.

It would be boring but here, things wouldn't be like that. He could do anything he wanted here

"Wait, she thinks I'm a mutant? " He asked

"Well that is a reasonable way of defining my existence but I have no X-gene in my body" he thought

He currently had information on everything concerning him from how he looked to his genes down to the very atoms that made up his body. He knew them all and individually.

There was no x-gene or latent Inhuman gene in him. He was a pure human.. Well not really, there were traces of Eternal DNA, Deviant and small traces of clear Celestial Meddling.

This omniscience ability was really something else. He could somehow tell this much just by wanting to know, It seems this life would be more interesting than he thought.

Change of POV

I have finally seen her, my mother. She was a lean woman standing at a height of about five foot six inches (5 '6 ft). She seemed to be a typical white woman but then her story told me that she had seen a lot.

I couldn't see her future just like I couldn't see mine but I could tell everything about her past and her current state of being. In simple terms, she was a beautiful woman who luckily found love early.

The man she is currently with, a James Smith. They had been together since high school but that was no longer the case, his birth had separated them and now, she could be seen crying in her bed.

"She's crying about the guy, wait till she sees the bill" He joked as he laid in the new crib beside her bed.

Well, it wasn't just a joke. The bill was very high, $26,000, that wasn't something she or the family as a whole could afford.

"You caused this! " She cried as she turned towards him

"I didn't though" he thought as he shrugged

Of course, the woman couldn't hear him but he could make it so if he wanted to though. The mutant gene was more likely to be passed in from the father so technically it was his fault.
