y/n x avengers 649

You are an ex-Red Room assassin, trained from the young age of 5 in the Russian facility that produced some of the world's best assassins from kids either sold by family or abandoned. You grew up and were trained in the Red Rooom, your high intelligence and bright mind leading to you becoming one of the most prized students of the instructors, your high athleticism and flexibility also contributing. Yoou ended up being moved up a group into one with others a year older than you, working on more advanced skills and with less leniency, so more death, as even small mistakes could end with death in the Red Room, whether it be from the guards or your own peers. Trust and friendship was drilled out of everyone, with constant drills like fighting each other or even using poisions of varying potency on others of any age. You graduated a year earlier than others your age in the Red Room, undergoing a series of tests before having a hysterectomy done upon completion. After that, you began to go on missions, stealing items, obtaining information or assassinating those who threatened the existence of the Red Room until one such a mission was interrupted by the Avengers, a group of some of the strongest individuals on and off the planet, ending with you being captured and released from the mind control the Red Room had put you under, later becoming a somewhat member of the group, though quite secretly to avoid any threats from governments or even from the Red Room. You ended up developing a hobby of running after grasping the cobcept of genuine freedom, but still retained a lot of the habits and instincts picked up on during your time in the Red Room...
