The fallen angel

After hydra lost three of their most important experiments the Winter soldier, the scarlet witch, and quicksilver, they needed new test subjects. That's when they decided that would be y/n, an extraordinary being with white wings, like some type of angel. They did experiments on her and lots of other things until they thought she were ready to work for them. Y/n's mission? Eliminate the avengers.

All rights go to marvel, Disney and all of them I am only borrowing the characters.
