You were once in HYDRAnas one of their top soldiers, but one day you had broken your mind control and escaped the facility you were once in. You had begun to go into hiding, hiding the powers you have due to HYDRA trying experiments on you for other super soldiers. You still have you powers and you memories of you training, so you know how to fight well. The Avengers caught wind of your location so they decided to go to where you are staying and knock on your door. (You can choose your age, name, height, etc. have fun my tigers)

So, you were with the Avengers for a long time, but you had kept hidden that you where in HYDRA. In your time in HYDRA they had fused your skeleton with Vibranium, giving you the ability’s of, being somewhat lighter than a normal human, being able to absorb much more kinetic energy than most, being more agile, fast, and a lot more quiet than a normal person. After the Avengers found out where you were hiding they had decided to try and recruit you as an avenger, after hearing about your time in HYDRA, and how well of a soldier you were. You choose your age, name, height, appearance, etc. (voice is random. I’m sorry 😞)
