HYDRA took you and your twin brother for experiments, you hated it when you heard his screams at night, until one night it all stops. You lose control over your powers ending up with a whole HYDRA base in flames, but before everything goes black one of the HYDRA experiments gets you out, when you recover from a year in a coma and some memory loss, you are then offered a place as an avenger, but you see a familiar face among the avengers and start remembering stuff before the HYDRA incident.
