(don't mind the voice) you are a hydra agent (code name is Phoenix and your real name is y/n) Originally you where in red room, but dreykov (the boss and creator of red room) realized you were not listening, and so he sold you to strucker (Hydra), he found out that you became deaf over the years, so now you have a special translator that goes on all your missions with you
STORY: The avengers are attacking a hydra camp and hydra is trying to fend them off, but is failing, so they need your help
(you can have powers if you want, or if not then that's also fine)
