The look Yaoyorozu had on her face after her loss against Tokoyami was one Midoriya knew all too well (IzuMomo/Izuku X Momo) Story updated to chapter 14 on Archive Of Our Own.

Midoriya Izuku starts a new phase of his life by attending U.A. High. But many obstacles still stand in his way, like a quirk that is still too much for his body to handle, a class full of students who would just die to discover that Izuku is All Might's son, and… villain attacks? Sequel to "My Hero Is My Dad?" and updated weekly.

Izuku was told by many that he would never be a hero, he wasn't strong enough, he was powerless, but he rejects them all he will be powerful, and unlike those with quirks he will craft his strength with his bare hands and use it to break the pillar of this world and stand atop the rubble as the most powerful. (VillainDeku) (BaneDeku)

We all know the story: After being hold he couldn't be a Hero by All Might, Midoriya Izuku still wandered over to a supervillain attack where he could save Bakugou Katsuki. But what if he had made the other turn? The answer is a butterfly effect that would lead him on a path to paving his own future. A path of revenge, finding his own moral compass, and doing the impossible.
