Many many Canon Characters are still available to be played!!!
Right now the only taken Canon Characters are; Tomura Shigaraki, Tamaki Amajiki, Ochaco Uraraka, and Hitoshi Shinsou
Every other Canon Character is ready to be claimed and thrown into the fray! (Exceptions being Eri and Koda since they wouldn't be 18+ even with the 8 year age-up for all characters)
