Summary
Was being a heroine at 12 a problem? Yes, especially if you had overprotective parents who treated you like you were weird.
But is that all she is? Not at all.
She is...
ATOM EVE
-------------
In this fic, Eve is the protagonist instead of Mark. I'll change some details from the Invincible story and add the Omega verse.
Instead of Invincible War, there will be Atomic War.

Summary
He lied about being a superhero. You lied about not having freaky ass mind powers. You broke up- bitterly. End of story. No shot Invincible and some superpowered grunt for Machine Head would ever work out in any reality. Except. When he comes in droves, hoards of himself, brokenhearted and wanting, wrecking cities for a chance to get one last glance at you.

Summary
Maskless Mark almost lost William. Existing in a rotting, war-torn world, eventually all that was left was William. So, he hadn't hesitated when he fled through a portal to an alternate dimension away from it all with his beloved. The problem was, that Nolan and the Viltrum Empire were still on the other side - but that hadn't stopped Mark from protecting William before...
A/N: My take on what would happen if Maskless Mark and the Original Mark still met, but Maskless never lost his William.

Summary
Nolan Grayson does not want his son's first interaction with True Viltrumite Culture to be when he wipes all governments off the Globe - so instead, he calls his mother - the mighty Thula Greis of Clan Uun, Krolulvek-Kraanvek (the World Breaker) and asks for her advice. The plan? Take Mark on a more kosher conquest of an Evil Empire, so he feels more ingratiated to the Viltrumites.
Thula sees an opportunity to ensure her line doesn't end, and calls her protege (and Nolan's Niece) to come help - the Djanchi Anissa Vokar of Clan Tazareth

Summary
Thragg had knitted his brows together as he observed you. You were a pathetic human like many others. Nothing less and nothing more, and yet… he was feeling something. Which was unusual for him. He couldn’t quite wrap his mind around it. Sure, you might have been attractive, but he had killed creatures far more enticing than yourself without even thinking twice about it. Yet your eyes, unfocused and bloodshot… and more importantly your warm tears on his skin, they were doing something to him.
