The Fallen Avenger

This is the story of Ace. She was born into HYDRA with no choice but to listen to what she was taught. Her mother had been an actual SHIELD agent once upon a time, before she ended up with Aces father, a HYDRA scientist undercover at SHIELD. Eventually Ace was born, and Kara Athena Riley was born. Ace's mother had homeschooled Ace, while her father had worked downstairs on HYDRA experiments and tech until her mom got sick. Ace was the one who took care of her and when her mother died Ace became one of her father's experiments. She lived that way for 4 years, where she was tortured, experimented on, and trained to be an assassin, a soldier of HYDRA. She endured until Thanos snapped away half the population, including most of the people working for her father, when the snap left a quantum device unintended, it killed everyone inside except Ace, giving her powers and problems along with the ones her father had given her. So the story basicly is gonna follow Aces life with Tony stark who will eventually adopt her this is my first story completely solo I have no refrances so guide the timeline it took me and this character is my child so be patient and feel free to correct me on stuff.
