y/n avery is a bad bitch super-soldier/spy that has worked for shield for over a century. she has been under the radar and the only person who knows who she is, is nick fury. they are quite close friends and they both have the flair for dramatics. y/n avery was taken in by hydra a century ago to become a super soldier like the winter soldier. she was chosen because of her looks, but even though she may look sweet she is the complete opposite. her and bucky bonded over memories and they got close, they were slowly falling inlove with each other. it wasn’t till they both got injected with the super soldier serum that they realised they were in a much bigger situation then they had made out. nisa most known as the wraith fought back, nothing like hydra could handle, eventually she broke out and tried to take bucky with her but it was too late. she had assumed bucky was dead and ever since then planned her revenge on hydra. the wraith is the only person hydra is scared of but the wraith is seen as a rumour, something that is meant to scare people, little do everyone know it’s true. nick furry sent nisa on a mission three years ago where she went mia, she was supposed to be undercover for another two years but fury pulled her out of the mission. she didn’t understand until she saw bucky standing right infront of her, along with all the avengers who have all heard the legend of the wraith.
