But she stayed volatile . Avengers begin fighting y/n when they get seen by them, y/n works alone. when the avengers see her. They see y/ns skill. They go in for a fight. Nat goes in first as one of the best assassins but.. y/ns , beating her fight? Y/ns stronger. * y/n grew up bullied. When y/n was 6 , they were taken by the red room because of their feistiness. Y/n grew up fighting and killing people she loved. Killing all her best friends for practices in the red room at 7 or 8 and going on my first mission to kill proper good fighters at 10. Before being taken. from 4 to 5 , y/n was bullied by older kids. 12 year olds. Hurt by them. But y/n always fought back. Y/n escaped the red room at 15 . Y/n continued hurting people on solo missions for pleasure and revenge. Went on until 17 years old, that’s how old y/n was when the avengers ran into them..
