My BnHA AU List
Sorry for the length. Fics that are currently available to read have links. To those of you mentioned in this post, I wanted to make sure people knew where the ideas originally came from. (And you’re all awesome anyway!)
Can't See The Forest For The Trees - Genderbent Midoriya Izuku who became a vigilante known as the Forest in Musutafu. Has been operating for five years dealing mostly with information gathering and dispersal and some smaller situations that crop up on the streets. Todoroki Shouto is on patrol in the area and takes an interest in the unknown vigilante after she helps out with a situation where he got in over his head. AO3
A Piece of Patchwork (Improperly Placed) - AU where Izuku and Aizawa swap places in canon. Izuku fights the hero system to become the first quirkless hero, graduating alongside Present Mic. He gets called in to help in a situation where the villain has the ability to steal quirks, five years before the start of canon, providing part of the back-up team for All Might. Part 1 is the battle against All for One, part 2 is an alternate ending to the fight. Part 3 is Izuku learning to use One for All, which was forcefully given to him by All Might at the end of the battle. Part 4 is the other half of the role swap, where Aizawa grows up alongside Bakugou and is trying to get into UA. AO3
The Fallacy of Greatness (AKA Tenth, in my files) - AU where the whole first year class of UA in canon is born 4 years later than in canon. All Might encounters a 10 year old Izuku who asks if he can be a hero. Even after rescuing Bakugou and proving his heroic spirit, All Might elects not to give One for All to a child as young as Izuku. Izuku, desperate for someone to believe in his dreams, realizes that he has to be his first believer and decides to take matters into his own hands and prepare for a future in heroism on his own. AO3
The Capture Scarf Caper - Based on an idea from @terrible-my-hero-academia-aus Izuku finds Aizawa's capture scarf discarded in an alley and takes it home. He figures out how to use it and becomes so proficient that it accidentally gets mistaken for a quirk. Deciding to capitalize on the strange bias he's come up against, he uses the capture scarf to get into Class 1-A. Unfortunately, this means his teacher is the original owner of his scarf. Suddenly his deception is a lot more desperate and precarious. Meanwhile, Aizawa is trying to figure out why his instincts are telling him to pay such close attention to this anxious kid. AO3
The Better Part of Valor - Suspected Traitor Izuku AU a la @gentrychild. After Aizawa discovers one of Izuku's hero analysis notebooks, he drags Izuku to an interrogation room trying to get him to confess to being the traitor in UA. Izuku comes to realize that several of his classmates were also made aware of this theory and have been feeding information on his movements to their teacher for a while. Betrayed, he starts to pull away from class, falling back into some of the same habits from middle school to go unnoticed and fall off of people's awareness. At some point, his classmates realize that he's no longer staying in the dorms, they only ever see him in class, and All Might is the only person he will voluntarily interact with.
Civil Disobedience - All Might doesn't track Izuku down after the slime incident, but Bakugou's parting words cut far deeper after the day he's had. Realizing that everyone talks about how great of a hero Bakugou will be, Izuku comes to the conclusion that he wants to be the exact opposite of what Bakugou is. He elects to become a villain who goes after and exposes corrupt heroes. Adopting the username Wasureta for his villain work, he collects information on heroes who aren't performing their job as they should and releases it to the court of public opinion, taking away the support that has kept them from being exposed before this. As he digs deeper into the cesspool of rotten heroes, he manages to collect enough information to rake Endeavor over the coals and ends up with an interesting new follower. Dabi, meanwhile, is shocked by the ruthless but polite teenager he found when he tried to find Wasureta and he's not sure if he's impressed by what the kid has accomplished on his own, or horrified by the scope of what he controls.
Hunting Prometheus - There is another quirkless student attending Aldera Middle School, but she wasn't born that way unlike Izuku. When she was seven, her quirk was stolen from her by a man with a smooth voice and a forgettable face and she's been existing in a state of carefully cultivated rage since that day. Before, she never even considered becoming a hero. Now her only goal is to become a hero so she can find that man and punch him in the face. (OC fic, obviously)
Lost Stars in an Indifferent Universe - Leverage AU, five parts, origin for each member of the team. Izuku is told to be realistic and he tries to be following his disastrous encounter with All Might. But realistic means that he has already exceeded the life expectancy of quirkless individuals, acknowledging the fact that no amount of studying or work will let him join a remotely helpful career, and he is stuck living with his mother while he wastes away as a janitor at a nearby middle school following the completion of his high school education. When he returns to a tall building he hadn't managed to convince himself to jump off of yet, he finds that the abandoned space has been taken over by a black market of sorts and gets folded into a world of grey morals and an underground economy based on merit instead of quirk. When he becomes aware of an illegal quirk experimentation operation and tries to blow the whistle, several attempts are made on his life in order to shut him up. Instead of disappearing, he gets angry and decides to collect a team to strike back and prove the shady shit the lab is up to. (Izuku=Mastermind, Shinsou=Grifter, Hatsume=Hacker, Shoji=Hitter, Eri=Thief)
Love and Other Things Not Bound By the Laws of Time - Mr. Peabody and Sherman AU. Nezu adopts a young Midoriya Izuku whose mother died shortly after he was diagnosed as quirkless. Determined to show his new son that one's quirk or lack thereof means nothing in the grand scheme of things, UA's principal develops the WABAC machine to travel through time and prove just how capable people were before quirks manifested. He indulges Izuku's passion and curiosity, encouraging him to look into as much or as little as he wants on any subject. It becomes clear that, while not supernaturally intelligent, Izuku is a genius whose ability to make connections and strategize is by far his greatest asset, especially as he still holds onto the goal of becoming a hero.
The Quiet Revolution (collab w/ my sister) - The Todoroki siblings need therapy. Instead of getting that therapy, they decide to meet up for dinner every Saturday night, begin a tradition where they burn their father in effigy each week, accidentally start a highly successful Minecraft YouTube channel, and generally cause the downfall of the existing hero system through the power of networking.
You Can Tell What I Am By The Lines In My Skin - BnHA/Naruto AU. Naruto dies in his own universe and is reborn into the My Hero Academia Universe as Midoriya Izuku. He remembers who he was, but his chakra, which followed him into this life, is always out of reach. He trains as best he can to keep up his regular ninja skills but can't break through the barrier separating him from his chakra. He still meets and trains under All Might. When he receives One for All, however, the sensation that fills him is entirely familiar. It breaks through the barrier as though it isn't even there, and settles inside like it's always been there. Honestly, he had been missing the angry furball anyway, so he was glad Kurama managed to follow him to this world. With access to his chakra again, the world is about to discover just how effective one shinobi can be in a world of heroes.
War Games - (Inspired by RogueDruid's Hero Class Civil Warfare and others similarly inspired by it.) A year-wide hero class exercise is announced. Bakugou is announced as the Hero leader while the villain leader's identity is kept secret. Izuku knows it's him before the letter appears in his room. The students are allowed to pick whichever side they want, but most choose the hero side, which has won the exercise every time it has been run. This year is no different. Todoroki realizes that Izuku is the villain leader and signs up with him. Izuku goes and recruits Momo and Monoma to his side. Then, after consulting the rules, he folds in Shinsou and Hatsume as well. Monoma plays decoy villain leader and attempts to collect a few more people, but they've already signed up for the hero side. Izuku, without explicitly saying that he's signed up with the hero team, gets folded into the hero strategy sessions since no one expected him to make a different choice. He proceeds to get "taken out" in the first villain assault, and most people don't realize what's happening until it's far too late.
Life's A Game (And I'm Player One) - AU in which Izuku realizes that he does have a quirk but can't tell anyone about it because a) he can't prove it and b) it could be dangerous if he talks about what he can see. His quirk, which he privately calls Stat Check, freezes time just for him in order to open up what looks like a video game character bio that explains a person's quirk, as well as containing vital statistics. It only works in person or on unaltered photographs with a person's face or a distinctive enough feature to identify them. As he gets older, more tabs are added to the bio, and he starts to notice signs above certain people's heads telling him what level he needs to be to fight them (he stops seeing these after receiving OfA, until he sees AfO in Kamino Ward). In pictures, only the first tab is available unless he took the picture while time was frozen, in which case all the tabs are accessible. Because of this, he has accordion folders filled with photographs of people instead of analysis notebooks.
Of Unpainted Fences and Raw Ingredients - Smart Izuku AU. He has been writing essays about hero society, morality, and several other issues since before UA, but he doesn't realize how much people are paying attention to them until the essays start becoming required reading for certain classes. Meanwhile, the teachers are desperate to get in contact with him, not expecting that the essayist they have been gushing over is sitting near the back of the class, trying not to blush.
In A Mirror Darkly - Aizawa is out on patrol with Shinsou and Midoriya when they are attacked and the boys are apparently obliterated by an enemy quirk. The rest of the class attempts to help Aizawa, but he blames himself for their deaths. It doesn't help that he keeps seeing flashes of them in the mirror out of the corner of his eye and could swear he heard one or both of their voices in the middle of the night. Meanwhile, Shinsou and Midoriya are stuck out of sync with the rest of the universe and can't communicate with anyone except Aizawa, and only through mirrors. Izuku figured out that they have maybe two weeks before they waste away since they can't interact with anything being stuck in this in-between space. The only way they can get out is for Aizawa, who was there when they de-synced, to touch them and bring them back in sync with the rest of the world.
Guerilla Tactics - Vigilante Class 1-A AU. After the slime villain debacle, Izuku runs away from Bakugou and the heroes. He literally runs into Todoroki Shouto and they commiserate about how the heroes have failed them. Realizing a bit late exactly who Shouto's father is and why he's trying to run away, Izuku offers to come up with a plan to help him get away cleanly. (This is sort of the worst timeline, where most of the good teachers aren't employed at UA, Nezu is not the principal, and the HPSC is in charge of almost everything.) The plan they come up with involves Shouto failing the recommended exam, then disappearing the day results arrive home. Izuku, meanwhile, attends the regular exam and sees how the whole points system benefits those with flashier quirks and easily aimed egos. He gets to talking with a lot of hero hopefuls and sort of steals them out from under UA when their applications are rejected. They move into an abandoned sector of outer Tokyo and start working as vigilantes. Dadzawa makes an appearance, as if summoned by the horde of teenagers with no form of parental guidance to speak of.
No Rest for the Wicked (Or The Damned) - Person Of Interest AU. Instead of apologizing to Izuku when he asked if he could still be a hero without a quirk, Inko points out the other ways he can be a hero, by building the things they would need to fight crime. Figuring that one of the main problems with villains is that no one knows when they're going to attack, Izuku creates an intelligent program that can assess a high volume of data and extrapolate when and where a villain attack will take place, and who the villain will be. When his mom is killed and he's badly injured in an attack his AI predicted, Izuku realizes that no one is taking his information seriously because he's quirkless. He decides to take matters into his own hands and reaches out to an unlikely helper. Dabi doesn't know why this kid decided he was the best option to stop a lot of the more violent crime he somehow knows is going to happen, but he promised and then delivered Endeavor's fall from grace, so he's willing to see where this goes.
Binary Stars - Slight Megamind AU. Before their respective planets were destroyed, Izuku and Bakugou were placed in small space pods and sent towards Earth. Bakugou's people were warriors who looked enough like humans that they intermarried (unbeknownst to humans), thus bringing about the first quirks. Izuku's people, however, are survivors. Their planet was populated by predators so their greatest asset was their ability to camouflage themselves. As Bakugou's people often hunted Izuku's people, they gained a sort of sixth sense for them, which is why Izuku's very presence pisses Bakugou off. (All for One is from Bakugou's planet. He was exiled for stealing power. The last power he stole was what he gave his brother, and the brother always resented him for getting them both sent away.) Izuku still receives OfA, and is the first of his species to have a quirk/power like that.
The Wings of Icarus - Spy AU. Todoroki Shouto works for Yuuei, an espionage agency run by his father. He's been training practically since birth, no thanks to his father, and is second in the spy business only to a person known as Icarus. When something goes wrong on a mission, he is rescued by a short man with freckles and deep green eyes shortly before he passes out. He is found at one of the entrances to Yuuei with a note from Icarus to the tune of "I think you lost this", making Shouto the only person to have actually seen Icarus. Meanwhile, Nezu is running a small but successful info brokerage out of a bakery with three kids he picked up off the streets years before: Izuku, Shinsou, and Hatsume. Codenames: Icarus, Psyche, and Daedalus, respectively. Nezu is known as Zeus.
Dark is the Night (Momo is Batman: version 1) - Based on an idea from @terrible-my-hero-academia-aus . Momo loses her parents in a villain attack when she's eight. She throws herself into her studies in earnest, determined to be a hero. In the meantime, however, she has a hard time ignoring all of the hardship she sees on the streets, all of the crimes that go unanswered. However, to duck the vigilantism laws and disguise her identity, she wears a suit that covers every part of her body (think Cassandra Cain as Batgirl) because no one would assume that someone with a creation quirk that needed exposed skin to function was under it. She produces everything she needs at home. Aizawa notices that there's someone off about Yaomomo, something fake. It isn't until he runs into her on patrol that he figures something out.
Used to the Darkness (Momo is Batman: version 2) - Based on an idea from @terrible-my-hero-academia-aus . Bruce Wayne was reincarnated as Yaoyorozu Momo. She remembers everything about her previous life, but she has adapt all of the fighting training she knows to her new female body. The intelligence and detective skills are useful in this new world, especially since a good portion of logic and deduction has fallen by the wayside for the majority of those in law enforcement. The quirk is something else to get used to, but it's highly effective at producing materials of various things needed for vigilantism. She's interested to see how far she can take the limits of the superpower this universe had given her. At the very least, she's more than capable of recreating the gear she had. Even though her parents haven't died in this universe, she still ends up going out at night and trying to help in whatever way she can. Upon meeting and befriending Todoroki Shouto, she realizes the good she can be in this universe. She attacked the corruption in Gotham wherever she could. Why shouldn't she be able to do the same here? The night is still dark and the people who hide in it are the same cowards they've always been. It's about time someone reminded them that the dark hides more than just their actions.
A Rose By Any Other Name (AKA the Haruhi AU) - Based on a prompt found on @rayshippouuchiha‘s blog. Midoriya Izumi is having trouble staying in uniform after starting middle school because her bullies have decided to step up the abuse a little bit and keep burning them. She had three sets of uniforms, and all three are burned by the third day of classes. What's more, the nurse doesn't have any spare girls uniforms and her teacher insists that she needs to be in uniform and not in her gym outfit. Since the nurse does have a boys uniform that would fit her, Izumi elects to follow her teacher's instructions and shows up in a boys uniform as she doesn't care as much about the clothes she's wearing as she does about following what her teacher said. Cue a gender identity crisis. AO3
Nothing But The Truth - Izuku is hit by a truth quirk while out on patrol and Aizawa is made to babysit him until it wears off. Although he tries to avoid more sensitive lines of questioning, Aizawa asks about his analysis notebooks and ends up accidentally learning about One For All, Izuku's life prior to receiving it, and what his Problem Child's true goals regarding heroism are. (Might become a series with this as a oneshot, or a multi-chapter story as originally planned.)
Panacea - Izuku has a hidden quirk his whole life, one that people didn't even consider could be a quirk. He has a super-powered immune system, and it can and will treat damaging quirks as an infection to fight. His burns from Bakugou's quirk heal faster and faster, emitter quirks used on him start to be less effective after the first couple of times until they don't work at all. He has the ultimate cure in his blood and no way to share it. And then he receives One For All, a powerful stockpiling quirk with a secondary aspect that makes it capable of passing from person to person regardless of heritage. Izuku doesn't realize it, but his invisible quirk got a free pass to start changing the world, one touch at a time. (Possible Dad For One) (Just had the stupid thought that Izuku's quirk is basically Cure For All)
Prototype - While getting scolded after the Slime Villain incident, an underground hero known as Prototype shows up and forces the other pros on the scene to back off. They then walk Izuku home (accidentally forcing him to miss All Might's offer). During the walk, Izuku confesses that he is giving up on his dream of being a hero since everyone says it's impossible. Prototype points out that Izuku was the only one on the scene who was thinking about a solution from more than one angle, which is a useful skill for an underground hero to have. They offer to take him on as their apprentice in the underground, promising that if he still wants to be a hero, an apprenticeship would be more flexible and faster than trying to become a hero through one of the heroics schools. They advise Izuku to think about it and discuss it with his mom, since he would probably be spending a lot of time training out of the house and not every parent is willing to let their child basically move in with someone they barely know. Izuku, after talking things over with his mom, decides to go for it, embarking on a totally different journey to being a hero than he ever expected.
Yesterday's Sunshine (A Storm On The Rise) - Based on @hey-hamlet's End of An Era AU in which the mind of a 19 year old Izuku fighting a losing battle against Paranormal Liberation Front and the League of Villains is sent back to his 14 year old body, a mere month after he started training with All Might. He is traumatized and trying to hide the fact that he is shocked to see the people he knows died walking around again, untouched and whole. He's determined to make everything better this time, to keep his loved ones from dying or betraying him in the worst ways. He also needs to try and stay ahead of the people around him, who are trying to figure out why this child who shouldn't have encountered many villains in his life, is so terrifyingly good at putting them down hard. (I'm considering adding an aspect of DFO.)
Searching for Tododeku - Or Five Times Shouto Tricks Midoriya Into A Date and One Time Midoriya Asks Him Instead. Featuring semi oblivious Izuku, Shouto stealth-competing for the title of supreme memelord with Kaminari, and a cameo of Endeavor's crippling addiction to tabloid magazines.
Planar Shift - An All For One-Izuku body swap just weeks prior to a fight that would have left AFO and All Might both greviously injured. Izuku is quick to realize that the person he ended up in doesn't seem to be a nice person (and he tries not to think about what it would mean if the person is in his body around Kacchan) and has a lot more quirks than a person should have. His childhood doctor is there, as is a strange boy with delicate skin, a disintegration quirk, and a love of video games but little else. Then there's the purple mist person who reads as both alive and dead to one of Izuku's new quirks. When he figures out that All Might is trying to track this villain down (and will probably think it's a trick if Izuku tries to explain his situation), he decides that he should get himself, the kid, and the not-dead-but-not-alive person out of there. He doesn't know how long he's going to be in this body, but he wants to be the hero those two need, even if he's technically a villain.
Environmental Damage - Hitman Izuku AU. When Izuku's mother is killed when he's young, he manages to track down the killer but the police won't take him seriously because he's quirkless. Neither will any of the heroes he approached with it. So instead he goes back to the criminal underground where he found most of his information and talks to an assassin who had a soft spot for him. Izuku agreed to become the man's apprentice so he can take out the person who killed his mother himself. After that, he starts selling his services to people who can't get out of bad situations, offering a much reduced rate compared to other contract killers. Then a kid his age with red and white hair approaches him about killing the Number Two hero.
Summertime and Seaglass - Aizawa keeps running into this mute homeless kid on his patrols. He's not sure what to make of him, except that he needs someone to care for him, especially as the nights are getting colder. Treating the kid a bit like an abused and feral cat, he starts taking food with him to offer the kid when they meet up. It's more or less an accident when he learns the kid's name is Midoriya Izuku, a child thought to be dead and burned three years before when he and his mother were caught in a villain attack that was ended violently by Endeavor. Aizawa wants to give Midoriya and all of the other victims of Endeavor's carelessness the justice they deserve, and maybe by the time he's done the kid will let him bring him in from the cold.
The Importance of Being Batman - (Based on an idea from @terrible-my-hero-academia-aus .) Izuku spends a lot of time on forums for quirkless people, getting support and advice from other people like him who don't have a quirk. He gets the attention of an old Admin, Toshinori, and they talk about heroics, pre-quirk comic books, and the importance of representation and symbols in modern media and culture. After failing to get into heroics in the entrance exam, Izuku shifts his focus slightly. Batman didn't have any special powers in the comics, but he was one of the best heroes in his universe. Izuku decides that if he can build the skills, knowledge and (most importantly) money to become his own version of Batman, that would be almost like being a hero. It's time that society learns that 'useless' is a matter of choice, not birth, and even someone who doesn't have a quirk can do incredible things.
