My name is Alyssea Stark. When I was 14 years old i was kidnapped by Hydra and experimented on. They gave me this serum that transformed me. Yes physically, it enhanced my abilities to hear, fight, see, and smell. But internally also. I was able to manipulate flames, I had Psychokinesis and Telekinesis. I could move objects at will. My mother was murdered when i was 4 years old. I had to move from London to New York to live with my father, that didn't bother to acknowledge my existence. So when i turned 6, i became the world's youngest assassin. Trained by Natasha Romonoff.
I consider myself an emotionless freak right now, but back then, i thought of it as a strength, so i couldn't feel weak. Till i was 12 years old, and wanted to clean up my act. Then i got kidnapped.
"I'm Steve Rogers' daughter and I have crucial information regarding an assassination being planned against my deceased father."
For someone who wasn't around that often, (Y/N) has to do a lot for her father; including but not limited to travelling into the past to save his life.
Steve Rogers' and Natasha Romanoff's younger daughter, (Y/N), has never known the superhero world, and the world has never known her. Forced into the past to form a functional relationship with her parents whom she has grown to hate, she realises her existence isn't half as inconsequential as she has been led to believe.
A/N: Slight AU and obviously i don't own any of the MCU characters.
