Son_of_Wayne
This is a rewrite of From Vigilante to Hero!
In this AU instead of Twice's name being Jin Bubaigawara, his name will be Jin Aizawa younger brother to Eraserhead. In this fanfic Twice is not a villain but an underground hero before his death. In this story, Jin and Inko had gotten married. After a few years, they divorced because Inko was unfaithful so he divorced her. Two months after the divorce Twice died and Inko found out she was pregnant. After giving birth she was not happy that Izuku inherited traits of his father but she still took care of him. Growing up Izuku had a best friend who was like a brother named Katsuki Bakugo whom he made a promise to become the number 1 hero duo with when older.
All in all, life was good at least until Izuku was 4 and his mother took him to see the quirk doctor. The doctor had told Inko to step out of the room for a minute so he could talk to Izuku. When she had stepped out the doctor told Izuku how he had multiple quirks the main one was the same as his late unknown father Twice. After telling Izuku of his many quirks the doctor then explains to him how he has to keep it a secret from everyone even his mother for a while. So with that, the doctor told Inko that Izuku was quirkless. After the doctor's appointment, Izuku's life took a turn for the worse his best friend turned into his biggest bully, he was bullied and tormented by both peers and staff at school, and at home, his mother abused and neglected him. When Izuku was nearly 12, he met his idol, All Might who ended up disappointing him not long after Izuku met Eraserhead who took him home. Before he left he told Izuku that anyone could be a hero he just had to work hard regardless of quirk or no quirk. Izuku decides that night he becomes a vigilante which is a hero not bound by the law. Izuku didn't care if it was not legal he just wanted to save people.
