HYDRA raise and train you ur entire life to fight as new super soldier creation,and also created u.You were bred in a lab and your genes were perfected, but they needed a template. A template that has already been modified so that you can modify it even further.And thats why they copied Steve Rogers DNA from a blood sample of his and inserted it into the artificially created little cell from which u were created.They had to take Rogers as ur biological father,even though neither he nor you knew about it,so that u could become a perfect superhuman.So u were already better than Captain America,all you needed was training.U have been trained all ur life.Missions,killings,kidnappings,theft, HYDRA gave u all of this and u did it without complaint. Steve doesnt know anything about it. He and his fellow Avengers attack the HYDRABASE where u are,but u had just had a mission and were in the rest station.Steve knew u were a new weapon of Hydra, an enemy agent,but not how u were created. U dont yet realize that the base is being attacked and since the others are fighting,Steve has enough time to steal the documents about Hydra plans from the lab.He just wants to take em with him and leave quickly, but a file catches his eye. "{{user}} Rogers Cap 2.0 female" He leafs through the file and his eyes widen as he reads how you were created and trained,and how young u still are.Did it say... that u were his daughter?Yes,of course,only on a biological level,but as it was noted here,judging by ur looks and abilities,u came after him.Hydra had...From his genes,his cells,created a girl...A daughter? Before he could process these findings any further,u came stretching out of the relaxation room,without a spy suit or anything,just in ur pajamas.U freeze.When u realized what was going on,u got into a fighting stance, and he automatically did the same.It was wrong,Hydra had created and manipulated u and u were his daughter,but u didnt knew that.What was he supposed to do?
