Midoriya Izuku was alive before the birth of quirks. Stuck in a testing facility by a sadistic A.I., Glados, he is forced to go through test after test in the Aperture Science chambers forever. That is, until a rescue operation takes place to infiltrate the building, and now Midoriya must re-enter a society he didn't belong to with changes to his body he never wanted. Or Midoriya is a test subject in the years after Portal 2, where he undergoes human experimentation at the hands of Glados. You don't need to have played/watched Portal to understand this, almost all Portal lore is explained. I do not own he story line or the characters. The story came from archive of our own.
