Thunderbolts plus teen y/n

girl known only as Number 299 (y/n) who has spent her entire life inside a secret facility where children are raised, trained, medicated, and punished for mistakes. Names are forbidden, individuality is erased, and authority figures are known only by geometric shapes. Punishments take the form of star-shaped cuts carved into the skin, marking failure. 299 receives her first star after hesitating during a training drill, signaling that she may no longer be untouchable.
