Y/N has been with HYDRA since she was 24, being kidnapped when her older brother, Steve Rogers, joined the army. Y/N was much like their new super soldiers, yet she was more powerful. She could control the elements and didn't age due to the experiments on her. She controls Earth, Water, Air, Fire and Darkness. All of which were given to her because of a secret formula called ALCHEMY X. ALCHEMY X was a secret for a very long time, only being compatible with subjects with the blood type X-, which, until Y/N, was unheard of. Y/N is known as ALCHEMY by those in the agency.
