When Katsuki and Izuku were 5 they both found out about them being quirkless. A few months later an incident occurred in which their parents had disappeared, and they were taken to a lab. The lab had experimented on them giving them extremely powerful quirks. Meeting many others like them, they became friends with many and soon escaped, also helping the entire facility to escape. Many went on their own path but some had joined Katsuki and Izuku on their journey. After a few years they were taken in by the League Of Villains.
