The Night Wolf and the Winter Soldier

You were Bucky's best friend in the 1940's, Evelyn Ash Blake. Everyone calls you Ava. When Bucky got drafted to the army you missed him. A lot. So one of your closest friends, Peggy Carter, pulled a couple of strings and you went to train soldiers with her after you were fully qualified. You were with Bucky when he fell off the train- you fell with him. And you survived with him. HYDRA made you to defeat Bucky in case he ever remembered who he was, the only difference was that HYDRA didn't wipe your memories like they did his. But what HYDRA didn't know was that during an experiment they accidentally gave you powers you would use to escape your torment...
