Thirteen year old Nathan Grey always felt like he did not belong in his world, believing that a world without superpowers and superheroes in it was not 'right', though he couldn't put into words why he felt this way, he just accepted it as truth.
Sometimes he thought he was weird, or perhaps a bit demented for thinking that way, but that all changed one fateful night as he went to sleep, when he learned that he was actually born in the wrong world.
Dropped back into the world where he was supposed to be born, he finds himself in the Marvel Cinematic Universe, with eight years to wait before the events of Iron Man kick off the MCU universe. He much use that time to strengthen his newfound powers to be ready for everything that will soon befall this world.
At least he's not totally alone, though.
