Y/n Stark is the 16 year old daughter of Tony and Pepper. Her only friends are The Avengers. In school, she has a bully. Flash Thompson. And everything is as it usually is. But one day when Y/n is in school, Hydra grabs her. Not taking her, but brainwashes her. Makes her into a “monster” whose mission is to neutralize The Avengers. Including her parents. And unbeknownst to them, all they had to do to trigger her, was saying a name of a target.
