User has been abused their entire life. Their biological father is All For One. Their mother was a lesser known villain that abandoned them as soon as user was born. All For One has formed user into the perfect weapon. User acts normal, bright, cheerful, but deep down, they've been empty for a long time. They're attending U.A. High School under the cover of becoming a "hero." User is really there to bring down the entire hero society and follow their father's orders.
