On her path to become a Hero she meets Izuku Midoriya, a virtuous young man with similar beliefs and a dark secret he keeps hidden within.

Izuku's quirk is Decay. A quirk fit for a villain. Yet his eyes are on UA. Izuku is an orphan, one of the lowest members of Japanese Society. A throw-away child no one wants or pretends to care for. Yet he aims high. He will show everyone what a real hero is, even if he is seen as something for something he didn't choose. We are dust and shadows. Izuku Midoriya x Hitoshi Shinso.

Extra bits and Omakes From The Emperor's Dragon. Could be extra scenes, alternative scenes or omakes. These are things that didn't make it into the main story but still might give someone a laugh or a smile or illustrate things in a different way. They are there because I hate writing something and not being able to use it somehow. Have a laugh or look at something differently.

AU, DFO Now after Kamino

So, Fanfiction's summary system isn't ideal, so, I'll just say that this is available on Wattpad and Quotev, too. (You can see the descriptions there.)

But, when All might kills All for One and Izuku is left all alone, he will be forced to make his own decisions. Or, Izuku has All For One and hell-bent on forming his own empire from scratch. Well, excluding the countless billions of dollars left by his father.

Izuku Midoriya has a fateful encounter with a multiverse manipulating villain and is sent to universe that’s not his own. Now he has to find his own way home. Little does he know, he’s not the only one of himself who’s trying to hop across universes. Expect references galore and infrequent uploads

Instead of being deemed All Might's successor, All Might criticizes Izuku's actions. All for One, monitoring All Might, sees this and decides Izuku could be a viable "Plan B" if Tomura fails. Izuku is then taken as All for One's second apprentice. (Rewrite starts at Chapter 5.)

Life was hard enough dealing with bullies and hate all day. His father's return should have been a good thing, one to help ease the pain. It wasn't. Even his father hated him; So much, that he took the only thing Izuku had left in this harsh world. The man's short return would be the mark for Izuku's new path, and it would be drenched in blood. So. Much. Blood. (Villain Deku) TW

A Villain Izuku story where Izuku's personality remains the same but instead of heroes he is a villain otaku who believes in the narrative convention that a hero is defined by their villains.

Full summary within!

A teen gets sent to mha into the body of a six year old with a broken quirk p.s I need a new title so any help is appreciated

The day Izuku Midoriya got One for All should have been the best day of his life, but it quickly turns out to be his worst. When 80% of the population suddenly vanishes, Izuku suddenly goes from a Quirkless nobody, to the only hero in the world. *Possible MHA & Vigilantes Manga Spoilers*

Izuku discovers that he actually was born with a Quirk, but his doctors kept it secret because of it's adult nature. The big problem is, now it's awakened and is far more powerful thanks to One For All. On the bright side, there's going to be a new generation of powerful heroes very soon, thanks to Izuku and the girls of UA. [Lemon/Smut warning]

Izuku Midoriya was always quirkless, that is until the universe itself gave him a sentient "Quirk" who is as violent as he is hungry. How will Izuku deal with the otherworldly parasite in his head while still trying to become the world's greatest hero? Slight crossover with the Venom movies.
