Summary
After taking a tumble off a cliff, "Izuku" finds himself with a brand new outlook on the world! Things have never been looking so good! Everything feels new, so many possibilities, but through it all, he's going to make the actual Izuku's wish come true. He's going to become a hero!
OR
Izuku hasn't been the same after going missing for a week, he's different, unnerving, and he'll take up the Real Izuku's mantle and become the hero the dead boy wished he could have been.

Summary
Midoriya is the best protector in his pod, but he fails them. A routine trip south for winter results in him being ripped away from everything he knows and holds dear only to end up as a prisoner upon Prince Katsuki's ship.
As to why the prince didn't kill him that first day, he can't seem to understand. Why is he still alive?
He doesn't care about that though. All he thinks about is how to escape and return to his family.

How to Raise a Child Nemesis by sabertoothhousecat for The_Lazuli_Witch
Fandoms: 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)

Summary
Every supervillain has a nemesis. All for One’s nemesis is a boy who, although he has all the skills required for world domination, continues to use them to be a thorn in All for One’s side.
Solution? Adopt.
It does not go as planned. Now he has a fake nephew who is still determined to take him down (outside of the house, anyway—they somehow manage to be a fully functional family when All for One isn’t doing crime). He’s read plenty of parenting books and none of them explain how to stop your kid from destroying your criminal empire.
OR: Izuku overthinks everything and intentionally gets himself kidnapped by All for One. Chaos ensues.

Summary
He’s Adonis. He’s showstopping neon. He’s smiling like he's the goddamn sun incarnate.
“Holy shit,” Katsuki breathes.
But there's no way. That cannot be Deku. Deku's quirkless.
...Right?
Or; Izuku got One for All but went to Shiketsu instead and ends up working at the same hero agency as one very confused, very turned-on Bakugou Katsuki.

Summary
But this was no typical thief. An ordinary thief didn't have a scent that made his knees weak, made his eyes tear up as he realized for the first time in six fucking months he could breathe, the bite mark on the side of his neck throbbing in the presence of the alpha that had left it. An ordinary thief wouldn't have stood at his entrance, eyes soft and smile genuine, arms reaching out to hold him. An average thief wouldn't say his name in such a way that sent his heart racing, making his child, their child, flip within his womb.
Because standing before him was no normal thief.
"You came back," Izuku choked out, his knife falling to his side, from his hands, clattering to the wooden floor they'd both built.
"Deku," Katsuki purred, "I came home."
"Get out of my den, Bakugou."

The Caretaker by daylightbreaks
Fandom 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia, 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
01 May 2026
Summary
The second lieutenant of the Shie Hassaikai yakuza group is known to others only as 'the Caretaker.' A rather enigmatic and highly intelligent member of the family, not much is known about him outside of a select circle of trusted friends and, of course, the Shie Hassaikai itself. But to those who know him, the Caretaker is simply this: a young man who cares for his family more than anything else.
Because the Caretaker is one Midoriya Izuku, and he did not start out that way... at first, he was just a babysitter.
--------------------
A series revolving around an AU I started in my fic, 'more than you hoped to be.' Originally only intended to be one fic, but it somehow sprung up into two! I might also include some other supplementary bits in this series as well, like scrapped scenes or character profiles for some of the characters in the fics, if people are interested in that sort of thing.

Summary
With graduation drawing near, the class of 3-A are eager to have one last chance to let loose and be kids for a change, before they step into the world as official pro heroes.
And what better way to do that than with a week-long field trip to a city of their choice?
And with Black Whip acting strangely lately, and a ploy devised by Katsuki and Izuku to fake a relationship in order to get their teasing classmates off their backs, one thing is for certain: it’ll be a trip that none of them will ever forget.

Summary
Midoriya Izuku is a bad liar. Yet, despite that, he somehow has to keep more important secrets than most. One for all, his hidden Vampire quirk, Kacchan's first arrest, all the good secrets that would take one slip to turn his life upside down. Moving into the UA dorms just adds to the pressure of keeping secrets, especially with 19 curious ears constantly around him.
It'd be pretty hard to explain why Midoriya was drinking a classmate's blood on a Friday night, wouldn't it? Hopefully, he doesn't get caught...
Or:
A drabble collection of Midoriya's vampire quirk only Bakugou, his mom, and All Might know about. Bakugou is Midoriya's human blood bag and All Might his surrogate-sire. 1-A is blissfully oblivious to the fact, despite Midoriya dropping way too many hints at his true nature.
Secrets are tested. Shenanigans ensue. Hilarity all around.

Summary
“Taking care of somebody else made me feel good. Like discovering you’re more than you thought you were. More even than you hoped to be.” - Bette Greene
In another world, Chisaki Kai is a ruthless, cruel man who stops at nothing to rid the world of quirks. In this one, however, he draws lines: one being Eri. He cares for her, treats her like his own daughter. And for his precious daughter, he needs somebody to help care for her, somebody who isn’t one of the Eight Bullets or a member of the Yakuza.
Enter one Midoriya Izuku: quirkless, protective, and the perfect candidate to be her babysitter. Now if only Chisaki could just stop worrying about the boy, too, that would be great. (No, Chronostasis, he does not have ‘paternal instincts,’ thank you very much!)
Or: Midoriya Izuku (accidentally) turns the Yakuza into the

Summary
Izuku sighed, and then realized he produced bubbles when he did that. The discovery made him giggle. Katsuki must have glared at him despite being half slumped in the water.
“Sorry. Bubbles.”
“Bubbles?” Katsuki asked in an annoyed tone.
“Yeah…uhh - I sighed and… and it… just, just look.” He did it again.
Katsuki stared at him for a moment. So, Izuku sighed again, but this time he managed to force the bubbled from his neck gills only. It tickled, which triggered another round of giggles.
“Oh my god, you’re actually a fucking idiot.”
_____
OR: Izuku and Katsuki get kidnapped...again. This time, they're chained to an anchor offshore, and given a week to get back to the surface before the quirk allowing them to breathe underwater wears off. But, when the quirk gives them more than they bargained for, will they even want to go back?Loosely inspired by this song: https://youtu.be/0Hd94r6GClY

Compliance by Getting1ASomeMuchNeededTherapy_Stan (Zanchev)
Fandom Compliance Verse - Fandom, 僕のヒーローアカデミア | Boku no Hero Academia | My Hero Academia (Anime & Manga)
14 Jul 2026
Summary
Of course he knows he’s a pawn. He’s far too intelligent to not have figured that one out. But, still, he complies. He follows along because who else does he have? He’s abandoned, Quirkless, functionally useless to civilian society. At least this way he can be as close as possible to his childhood dreams of heroism.
___
Midoriya Izuku is many things; Quirkless, an Asset, a tool to be used by the Commission. One thing he thought he never could be, one thing that he wanted to be above all else, was a Hero.
And then the Commission sent him to UA.
