Midoriya Siblings AU: Sometimes a single change alters the story. What if Himiko Toga is found by Izuku, rehabilitated, and adopted into the Midoriya family before they both end up enrolled at UA?

"Make sure that your dreams are attainable, realistic, understand?" Those were the words spoken to Izuku Midoriya as his idol left him on the rooftop. Dreams shattered, the green-haired boy contemplates just ending it all until a soft voice speaks into his mind... "Hear... Feel... Think." [MHAxFFXIV Crossover, Izuku/Poly, aged up characters, UA is a University]

Katsuki Bakugo dreams of becoming the number one hero in Japan. Mirio Togata wants to find purpose again after following his intuition leads to disaster. Tamaki Amajiki desires only to support his friends, no matter what that means. Dabi craves revenge, hoping it will ease his pain. None of them realize how destructive their desires will be for themselves and those around them...

One night the Bakusquad takes a walk and it goes unplanned

Reshaping the world one villain at a time was never going to be an easy task. It definitely wasn't what Toshinori imagined would be his calling once he'd retired from pro-hero work. Results yield a call for further trial runs of this new 'special rehabilitation program' where Tomura Shigaraki is the 1st shining example. Unfortunately for him and others to follow in his footsteps.

The day Ippan was saved by Deku she became his biggest fan. But she desires to be more then just a fan but at the same time what would Deku see in a girl like her?

What if Eraserhead was too injured after the USJ to teach Class 1-A, and Nezu called on Ingenium and others to be Aizawa's substitute while he recovers? How will this change ripple out and lead to a different outcome? Rated M for content/language. Also, self-indulgent Speedbunny and IidaMomobowl because why not have Class Parents couple fall ass-backward into a poly harem lol

Quirkless and powerless Izuku Midoriya thought his miserable life would never change. However, when things looked like they were about to improve, he discovered just who his toughest roadblock in his path to greatness was: himself. But that's ok. He got a rabbit girl to punch some sense into him. If only his quirk wasn't so weird and embarrassing... Teenage Mirko and Kitsune Izuku

Can class 1-A handle another fire quirk? Why does this girl mean so much to All Might? And can she cool off our favorite hot head?

My Hero Academia from Ochako's point of view

Izuku Sasaki's life was suppose to end on a roof top, his father had predicted it so. And yet, the world had a different idea. There will be friends, enemies, and families formed but first he must pull upon the strings of fate to reverse the clock. To save not only his own life but the lives of others, and bring to light the horror's of his past.

A small ripple can lead to huge changes. So it's to be expected when Izuku's cousin moves in, things get crazier!

Izuku opened his eyes and sucked in a breath. Yagi's eyes had flashed with surprise when Izuku had thrust him over the building's ledge. It was from this very rooftop Izuku had thrown his idol. It was from this very rooftop Izuku felt One for All rush to his fingertips. [cross-posted on ao3]

Children often inherit their quirk from their parents, one or both, they can also inherit stronger versions of a parent's quirk. Izuku can manipulate small things and the implications of that allow him to become not only a hero but the worlds greatest hero! OP!Izuku - Matter Manipulation

They say twins share everything, but Minako Midoriya's Quirk was all hers. She feels guilty she has a Quirk and her brother doesn't, but what can she really do? She supports and defends him the best she can, but she can't just pretend her own dream doesn't exist when their third-year of junior high is coming to an end. Katsukixoc slow burn

Quirkless Villain Deku story, All his life he suffered because he believed he can be a hero because he was weak. Now his suffering has led him to the path of becoming a brutal cunning villain hellbent on becoming strong and showing everyone the weak are strong. Rated M for cursing and other reasons. Slow burn story and relationship, slight redemption arc.

Kiyoko is the daughter of a pro-hero with a goal of being one herself. Her quirk is one, not even her dad had heard of before and she's scared she'll be seen differently because of it. With her dream on the line, will she be able to give it her all to go push past her fears? (Title may change later.)

She's a QUIRKLESS hero in training. She has a lot to prove to make it as the world's first powerless warrior. She believes that everyone should have the ability to defend themselves against villains rather than waiting for heroes to save the day. Chise Kirita is her own hero. She applies for UA with the sole purpose of being the first quirkless superhero. How will she survive?

Mayumi, an underground fighter, is torn between standing with what she believes in, and an attempt in repaying an debt that she knows she can never repay. For that, she has to be a student in U.A., and it was the last place Mayumi wanted to be in. Being a hero was stupid, and wanting to become one is even more so. What good was being a hero when you can't save everyone?

When All Might died, killing All for One in the process... The world was left wanting for a new icon as villainy rates skyrocketed. No one, however, could ever hope to take All Mights place as Symbol of Peace. There was no heir to the symbol, and people came to realize there never would be. 7 years and one long war later, Ochako has just returned to duty after a year of therapy...

Midoriya Izuku got expelled on his first day. Nedzu took it personally. Or: How Nedzu decided to turn a problem child into a gremlin and teach Aizawa an important lesson. Who needs a quirk when you have a sledgehammer and low ground advantage?

Rather than being a quirkless human, Izuku is a quirked animal. Specifically a green rabbit that would stop at nothing to be a hero no matter what species he was.

Everyone knows that Izuku's father is Hisashi Midoriya, a faceless absentee dad with a fire-breath Quirk who took a work post abroad. Except, in this AU Izuku knows better. Izuku knows exactly who his father is... and in fact has a great relationship with him. All For One and his son have been plotting the theft of One For All for almost as long as Izuku has been alive...

Izuku would never understand what compelled Setsuna to take a liking to him, but whatever it was, he hoped it wasn't a simple reason. If only he knew it was just because they both had green hair. (Izuku X Setsuna)

Life was unfair. Izuku found out just how unfair it was at the tender age of four. quirkless, abused and looked down upon by society and his own mother. this is the story of how he became the greatest hero in the world Or a fic in which Izuku is abused and we get to see the ripples that it creates through the universe of My hero academia and the characters themselves
