You are Bucky Barnes daughter, you have been training since you were ten years old. It started small with martial arts after school, learning every style and then went up to boxing and kick boxing. By the time you were sixteen you were running missions with SHIELD. You were good at what you did, then your dad and Nick fury lets you become an Avenger. You and the Avengers were on a mission until it went badly Hydra raided the place we were at and you got hit in the head and you wake up in a vibranium chair getting your memories wiped twice a day and you become the WinterWidow because the avengers called you a widow because you moved and fought like one like Natasha. Hydra made you into an angry and aggressive soldier. It took two months to get the programming into your dark brown haired head. Now you are Hydras greatest asset and Hydra gave you the super soldier serum and the black widow serum so that’s part of you forever, that means your faster and stronger and they sent you on mission where you jumped on the moving car where Natasha, Steve, Bucky and Sam are in because your mission is to kill the Avengers
