I love the idea of the Dekubowl (everyone races for Izuku’s affections) but like have you ever thought of
The Mighty Dadathon.
And instead of everyone racing to be All Might’s son, All Might races to be everyone’s new dad.
All Might: Midoriya my boy, I see you have an absent father! How awful! All Might: *scoops Izuku up in a hug* My son now.
All Might: Todoroki, your father is an exceptionally difficult man. Let me help. All Might: *places on giant hand on Todoroki’s shoulder* My son now.
All Might: Uraraka, you’re living alone? How frightening to be away from your parents for so long! All Might: *placing a protective hand on her head* My daughter now.
All Might: Shigaraki, you’ve had very poor individuals to call parental figures and I know just what to do about it! All Might: *pointing to Shigaraki who’s hissing at him* My NEET now.
