This is the story of Brooke Rogers. Brooke is 14 years old and is a lab experiment, she was 1 in 1000 to have survived the experiment. The experiment was to use Steve Rogers' DNA to make a child just like him and Brooke was that child. She didn't look like it though, she looked very petite but she was strong, fast and very flexible.
Since the age of 6 Brooke has been used as a weapon... For SHIELD. Fury never told Steve, why?
Steve wasn't ready to find out about his daughter or the fact that she went missing at the age of 10. But she's back, she's bad ass and Steve is going to have a heart attack!
