When the infinity stones are destroyed all their power is lost right? Wrong. Whilst the avengers were busy dealing with Thanos they didn't notice all of the stones' power going into one girl. This girl just happens to be HYDRA's best assassin. What happens when the avengers find what they fear most... inside a teenage girl? Will they see her as anything but the cold blooded killer she is? Obviously I don't own any of the characters apart from a few that I am going to make up along the way.

Y/n, a full time Marvel fan, has always been fascinated with the MCU. But what if she gets to be part of that world? What if the Multiverse is real? Follow the story of a girl in her 20s as she gets to experience the Marvel world in her skin and fall in love with more than their characters.

When a girl suddenly appears in the Avengers Compound living room, everyone is stunned. More as the girl appears to know each of them and their deepest, most secretive struggles. But little by little the Avengers warm up to her, surely helped by her franchise, her joy and her understanding personality. She even offered herself to be kept in a cell until they made up their minds. "I don't belong here, I shouldn't be here", I shout. "You belong where your heart lies", he soothes, "and if you feel it's here then you don't have to feel guilty." #2 in MarvelAU thank you so much !!!
