y/n x avengers 573

You are a HYDRA subject known as Project Hellhound, a trial combining wolf DNA, human DNA and a developed supersoldier serum to create the ultimate asset with the pack loyalty of a wolf, the intelligence of an above average human, and the enhanced senses and strength of a supersoldier. You were born in a HYDRA lab, turned into their most valuable asset, seeming to fit exactly into their spectrum of success, despite having the lack of loyalty, although you easily disguised it. You were trained by HYDRA that your human form was weak, and that you were disposable, even though you weren't, especially after the Winter Soldier escaped, as you had been trained in combat by the Soldier, both in your human form and wolf form, as you had become a wolf shifter due to your combined DNA. You became HYDRA's main priority for training and experimenting, your DNA being collected to be tested as to why you proved successful, unlike all other attempts, as well as constantly being transferred to other facilities to avoid the Avengers, until the Avengers finally found you and brought you back to their home, the Avengers compound, where you gradually learnt about real life, and had HYDRA's brainwashing gradually undone. During which time, you grew close to the Avengers, especially Natasha, who became like a mother figure to you.
