Y/n is a mutant
Y/n is a twelve year old mutant that is in prison for assault, but they don't know it was in self defense. Not to mention her abusive parents that threw her out when she was five with her 3 year old sister that died. And still not mentioning that Secreatry Ross is trying to get information of her so he tortures her. Also she has magnetic powers, so what happens when she gets in contact with the Avengers?…
