“I am your father.”
Darth Vader, Star Wars
I just had a disturbing idea regarding My Hero Academia. I believe that All For One, the most powerful and sinister supervillain in Japan, is Deku’s biological father. Since the start of the series, Deku’s father has been notably absent from the story. Supposedly, Deku’s father has been “away on business”, according to Deku’s mother. However, I think Deku’s father has not been absent from the story at all. Thanks to Doctor Ujiko, All For One acquired a quirk called Life Force, which greatly extends his longevity, which has allowed him to remain active for over a century. I think throughout his long life, All For One has undergone many names and aliases in order to remain hidden. Doctor Ujiko, who also has the Life Force quirk, has done the same thing in order to conceal his identity. Perhaps, while assuming the name of “Hisashi Midoriya”, All For One thought posing as a wife and husband would make it easier to cover his tracks from All Might. One must remember that Doctor Ujiko was the exact same doctor that Deku and his mother went to see when Deku was a child. The doctor revealed that Deku was quirkless, but I think there was more to it than that. The fact that Ujiko was the physician that claimed Deku was quirkless means that All For One was involved. All For One is infamous for stealing the quirks of others and making them his own. Maybe Deku did have a quirk after all, but All For One discreetly took it from him. That would mean that Deku had a quirk that threatened All For One so greatly that he had to strip him of it. Maybe Deku inherited the All For One quirk and All For One himself saw Deku as a threat to his plans. If All For One is Deku’s father, the fact that he was absent in the story could also be connected to when he was weakened by All Might. There is a delicious sense of irony to All Might taking Deku under his wing because he would unwittingly make the son of his mortal enemy his successor. This would be similar to how Tomura Shigaraki became the apprentice of All For One since Shigaraki was the grandson of a One For All wielder. If All For One is Deku’s father, was Deku’s mother aware of her husband’s true identity? If this theory is true, All For One may have sired Deku, but he was never Deku’s father in bond. All Might has been more of a father figure to Deku than Deku’s own father has been. All Might was the one who bonded with Deku, raised him in the ways of the superhero, and supported him every step of the way. I look forward to seeing if this theory is true in future chapters.
