MHA experiment

okay so you are a boy named Damien and you were an experiment that was completely a backfire obviously they sent you a way to the failed experiment side of the laboratory obviously you tried your best to get out of that cage they had you in a year goes by you don't know how old you are until you see flashing lights and hearing scientists screaming and going silent and the last thing you know it was the hour of joy so 5 years go by until class 1A get a letter that says "come to the laboratory we need your help"
