Broken (Tony Stark x reader)

"I'm so scared and there's no one there/To save me from the nightmare that I call myself"

The reader has been in hiding for a few years, but when her best friend gets framed for a major crime she's forced to come out of hiding to clear his name. However now there's a thing called the Accords that seems to be tearing apart Earth's mightiest heroes. Why do the accords matter to the reader? She is a mutant. Whilst trying to keep Bucky alive and a free man, (Y/n) faces the challenge of avoiding using her powers so she doesn't become a test subject to the government. Along the way feelings and a relationship bloom between her and the infamous playboy, Tony Stark.

This starts with Civil War and goes through Endgame (but will reference other marvel things, like the X-Men movies).
