Midoriya Izumi didn't make regular friends growing up. Quirkless and moving to a completely different middle school made it difficult to pick...human friends. Izumi became friends with Japan's crows, giving her an insight her human teachers couldn't, and became Karasu, the Black Bullet Killer, a gun for hire and hunter of heroes, and shaking up Japan from the Underground up

A freak accident kills Izuku and his team during the UA Sports Festival. Fortunately, a goddess offers to resurrect him if he manages to save a fantasy world. Unfortunately, that Goddess is Aqua. Kazuma thought he was going to live a cushy retirement in the Divine Realm, but when an irate bird-boy chooses him as his bonus, the only way back to NEETdom is by saving the world. Again.

Eijirou looks at the talisman. And then does a double take. "This just says 'fuck off' in kanji," Eijirou says to Midoriya. "It's very effective," Midoriya says to Eijirou. "What the hell is going on," Jirou says to the room. (In which the dorms are haunted and Midoriya is an exorcist. In, you know, a manner of speaking.) [WARNING: manga spoilers]

The vigilante in white breaks from his position and proceeds towards the man known as All for One. In his wake, he leaves behind the wounded form of All Might, emaciated into his true form. Unable to move, Yagi Toshinori could only watch as the feeling of cold water begins to envelope him and take him away from the fight, leaving the fate of hero society in the hands of another.

Hisashi Midoriya isn't All for One. The two of them just look exactly alike.

A young soldier from a once great family is thrust into the future and ends up in an unfamiliar and bizarre world, where his presence can cause complications both ancient and modern. He inadvertently becomes a trainer through mere misunderstanding and sets off in a journey to discover his own self and where he stands in a world that isn't his own.

People often say that 'you are what you eat'. What does that make Midoriya Izuku, who eats both heroes and villains? Join everyone's favorite cinnamon roll as he turns his notebooks into cookbooks. Cannibal Quirk Izuku AU, loosely based off/inspired by Tokyo Ghoul. Rated M for graphic descriptions and cannibalism.

Quirks are bullshit, Izumi's quirk just so happens to be an extra level of bullshit that she has to spend a fuck ton of time trying to figure out. Fortunately for the villains there's a good chances she'll explode herself, but if she survives, the next top hero might be a beautiful green haired woman that rides around on a broom. Female Izuku, Wizard Izuku, Izuku will not get OfA.

What if instead of Kazuma, the world of Konosuba gets the Number 1 cinamon roll of the hero world? Find out in this experiment of a crossover!

While high on painkillers at the hospital, Izuku creates a troll twitter account pretending to be All for One. The League of Villains, the Hero Public Safety Commission, and All Might all fall for it.

Dual Quirks are rare and highly sought after for both Heroes and Villains, and Izuku is one of those with Dual Quirks, even though his Quirks aren't really Quirks. AU and X-Over.

A mysterious vigilante with the power to bring dreams to life. Is he a hero or a villain in the making? Izuku's quirk has brought him only misery, but maybe, just maybe he can turn his curse into a gift and become something more than what he is. Maybe he could become the king of dreams.

Though labeled as 'quirkless', Izuku still plans to become a hero despite everything that might come his way. But as fate would have it, his quirk eventually emerges. Strangely though, his power appears to be similar to a certain pun-loving skeleton from Undertale. [Side note: Don't worry, he won't actually turn into a skeleton. XD] Cover image by KingOfFatCats on DeviantArt.

Kindergartener Izuku wins an exclusive tour of Might Tower. His father, All for One, tags along to gather intel and sabotage defenses. Unfortunately, his sweet, innocent Izuku excitedly repeats every single rude thing his father has ever said about heroes to tour guide Sir Nighteye. As the tour continues, All for One's goal rapidly shifts to not being arrested as a villain.

After Izuku's analytical ability is revealed while playing video games, Izuku begins working with his classmates on their quirks. Can this help the rest of class 1-A though? Spoilers: Yes, yes it can. Figuring out how will be the interesting part though.

The Holy Grail, the once key to the Root of all Magic. Once Destroyed and now restored. A force that favors neither good nor evil, now reformed and seeking to begin the Holy Grail Wars anew. Two Symbols, one of Peace and one of Fear, their seven Masters, and the war to determine which will survive and be restored. Pairing undecided.

What if Izuku unknowingly possessed a "sentient" Quirk like Tokoyami's Dark Shadow? Enter Midoriya Izuku, a young boy thought to be Quirkless who subconsciously controls the number one vigilante in Japan; an entity powerful enough to rival even the strongest villains. There's only one small, tiny problem: the entity thinks of him as a big brother. Good luck, Izuku-nii-chan!

Izuku got beaten up for saving someone. By the one who was supposed to be his friend. No one helped him. Ever. And laying under that tree, beaten up, he came to a gruesome realization. The realization gave him the drive to chase his dreams past the limit of men! Go beyond! PULS ULTRA! OP!Izuku. OOC!Izuku. Now has a TV Tropes page.

Quirks come in all shapes and sizes, Yet there are some quirks kept secret from the general population because of the potential they hold. These are Kaiju class quirks. This is the story of one such quirk and how Izumi Midoriya will come to terms with being the of the monsters

My take on a multiverse crossover story. Featuring my different villain Izuku ideas. Some of them get weird so be prepared for that. Don't take the story too seriously, this is just me having fun.

After being hit by a strange quirk, Izuku finds himself holding two white-haired brothers who claim to be from the past. When All for One takes an inexplicable interest in the time-travelers, All Might volunteers to protect the adorable brothers. OR: All for One loses his shit after his younger self and his long-dead brother travel forward in time and get adopted by All Might.

Izuku has a Quirk. Its function is simple, and it definitely isn't flashy, but the implication of what it can achieve... now that is another story entirely. In the hands of someone like Izuku, the power to go into the Multiverse might just turn him into the most powerful Hero in history. But the Multiverse is not a kind place...

Deku's dead. Katsuki should finally be able to move on with his life. Yet, the next day, Deku's at his desk, and no one else can see him.

Deku had enough. He had been told how useless he was, and, one day, he just... broke. But that was not the end. In the midst of his pain, a realisation comes to him. Now he's back, stronger than ever, and COMPLETELY CRAZY! Anyone wonder what sound a Nomu makes when it takes a cheap shot? Rated M for the heavy backstory (CH 1), but this is a comedy. Quirkless!Deku

On his way to grab a snack, Bakugo overhears an unusual question even by 1-A standards. And after all the weirdness that he's suffered through during his first year, he's ready to get involved in the madness rather than get caught off guard later. So the question is: is it a twin or a clone?

When the most precious members of Japanese society start showing up having been turned into vampires, Hizashi Yamada and the rest of the crew at UA go to Nezu for answers. And hoo boy, does the principal of UA have quite a lot to answer for. (Sequel to 'Hizashi Yamada vs. the demon horde') (Rating pending)

Hizashi and his fellow UA staff members are drawn into a conflict that was spawned centuries before the era of quirks first began when a mysterious demon girl seeks to capture another one of Hizashi's friends that his co-workers are surprised he has. (Sequel to 'Hizashi Yamada vs. the zombie apocalypse') (Crossover with Demon Slayer) (Crack fic elements) (Rating pending)

After making a bad choice in trying to fix a worse mistake, UA teacher Hizashi Yamada, aka Present Mic, now has to quell a zombie outbreak before it can have a chance at leaving UA grounds. Crack fic elements are present here and there. (Rating pending)

Dabi would like to state for the record that he attended Shouto's parent-teacher conference by accident.

Age is a number. What matters is ability. Midoriya Izuku, AKA, the Pro Hero Revan, the youngest Pro Hero in the History of Japan at the age of 13, is about to tackle a challenge that most are not equip to face: Teaching people the same age as him to be Pro Heroes. Sometimes, Izuku regretted saving All Might. That deed killed his anonymity.

All for One strikes a deal with a demon to heal his wounds in exchange for his first-born son. He intends to scam the demon, since he never plans to have children. He forgot about his one night stand with Inko Midoriya many years ago.

"I'm completely shirtless, and if it wasn't for my boxers and socks I'd be stark naked." Izuku responded blankly. "I really don't wanna be talking about my penis right now."

In Musutafu Village, everyone tames dragons. But the other kids call Izuku useless because every single dragon inexplicably dislikes him. Until Izuku meets All for One, the dragon who hates humans…and who absolutely adores him?

"I didn't mean to do that," Ochako says. "I swear, oh fuck, fuck, I didn't mean to do that—I'm sorry, I'm sorry—" "Calm down," Izuku says. [An unfortunate accident happens in the final weeks before they graduate UA. Fortunately, good friends are not that hard to come by if you are in the notorious class A. And you know what they say about good friends and dead bodies.]

Percy is the son of Poseidon's most destructive aspect, it's natural things get a little... mixed up morality wise. Poseidon is just so proud of his overpowered son. Zeus wants him to please stop making things break.

It was a simple mistake. The nurse could hardly be blamed. After all, babies look the same right after they're born.

Izuku never made it to U.A., despite his best efforts. Two Alders students tried to get into U.A., but only one managed and now Izuku's just going about his life. Meanwhile, Princess Elise the Third is coming to Japan to give a speech at U.A. about the effect Japan's heroes have on standards around the world. So what happens when she meets Izuku Midoriya before anyone else?

After convicting Hisashi Midoriya of being a deadbeat, Principal Nezu invokes an ancient U.A. tradition to find Izuku a new father. Both Izuku and his half a dozen potential fathers are roped into the Bachelor Dad Style whether they like it or not.

Shouto Todoroki has figured out that one of the students at U.A. is being haunted by seven and a half ghosts. Unfortunately, he thinks it's Hitoshi Shinsou. And he's recruited Izuku to help him make a video proving it.

After Kamino, the heroes found an underground facility containing tubes with hundreds of clones of the same white-haired man, in various stages of development. Izuku felt icy nails of despair rake down his spine. (He wondered if he could ever truly escape.)

Hitoshi Shinsou thinks that Izuku Midoriya might be haunted.

Against all odds, Shinsou Hitoshi makes it into the hero course. He has no idea how, but he's not complaining. And even better, a bunch of people seem to want to be friends with him in spite of his quirk. His high school life at UA might actually be just as amazing as he'd always dreamed. Then the attack at USJ happened. And then students started going missing...

Izuku and Momo have been friends for years despite their wildly different stations, and their favourite game to play together was always "Pirates and Solidiers.", in fact Izuku would claim Momo was obessed with pirates. So what will she do when he gets kidnapped by them in an attack on their village?

Demon Prince Izuku has always been jealous of children who have fathers. So when he gets summoned by the human All for One, Izuku drafts a contract to shanghai the villain into becoming his dad. OR: in a reversal of the usual Dad for One trope, All for One is forced into father-son bonding by an overpowered Izuku and suffers almost as much as he deserves.

During a training session, Izuku and All Might team up to defeat Class 1-A.

Fourteen years ago, All for One's infant son and the Midoriyas' son were accidentally switched. Yesterday, Japan's greatest villain started looking for his lost child.

Izuku Midoriya doesn't know what he's getting himself into when, on what's supposed to be a casual night out with friends, he encounters a villain with a transformation-type Quirk. Suddenly he's got breasts, cat ears, a cat tail, and a love for eating fish and getting headpats. Just what the heck is going on here? (Catgirl Genderbent Izuku, yuri.)

A series of snippets and AUs containing fluffy Dad for One content and murderous brotherly love, loosely connected to my fic Custody Battle. Including: Four Ways the First User Could Have Died; All for One bonds with his son while Izuku tries to stop him from killing people; and How All for One discovered he couldn't steal his little brother's quirk.

Izuku accidentally swapping bodies with Mineta? A problem. Izuku accidentally swapping bodies with Mineta right before his villainous father shows up to vault him? An opportunity. (OR: Izuku makes lemons into lemonade and All for One discovers there could be worse sons than one who wants to be a hero.)

Featuring bad matchmaking, aggressive flirting and Midnight being an irresponsible adult.

Ochaco Uraraka is adjusting to her new life. Leaving her cramped apartment to live with Izzy was sudden, but they're doing their best to make it work. It would be a lot easier to settle in if the Hero Association wasn't trying to ruin her career and Izzy wasn't keeping secrets. Mysteries continue in this swing inspired Villain Deku AU! Sequel to In the Swing of Things

After the dragon empress Inko becomes pregnant, she knows she must protect her son from her overbearing and vault-happy husband. So she runs away to marry King Toshinori. The family of three lives a blissfully happy life until Izuku falls from a cliff and sprouts wings, and All for One returns for his son.

It was Mei Hatsume who told Izuku Midoriya that he could be a hero, with her help of course. Desperate to have someone believe in him, Izuku decides that to realize his dreams, he'll need to make himself into a hero with the help of this odd girl. Together, these people once rejected for not fitting the mold will find themselves becoming the foundations of hero society.

A time-travel accident leaves Izuku de-aged to six years old and stuck in the 21st Century with his villainous father, All for One. To Izuku, this is a nightmare. To All for One, this is a second chance, not only to raise his unruly son right but to prevent his baby brother's betrayal and later death. The First is just horrified someone copulated with his elder brother.

When Izuku was born with 4 arms, everyone thought that it was the entirety of his Quirk. But when Izuku was 4, he discovered a new aspect of his Quirk, one that would change his life. Izuku Midoriya discovered Ether and became a true Kell.

Ochaco Uraraka is having an...off time. Her boyfriend's left her after five years. Her career isn't going much of anywhere, and she's been living in a terrible studio for too long. If only someone could give her life a little jolt... AU Villain Deku. Pretty much me trying to reconcile all the suave Deku images out there with his nerdy self and listening to too much swing music.

Instead of thinking about quirks, he thinks about his recent client, an old woman by the name of Sato Mio. One of her friends had shared the news of a kind, young teenager who went and found her dog, and she came with the quest of looking for her missing cat. Imagine her face when she met a tired, sarcastic teen who asked her to "Come into my office. Yes, the restroom."

This time, the usual audience is brought in by the usual Realmcrafter to watch alternate versions of everyone's favorite cinnamon roll boy. The differing forms of Izuku will take many watching by surprise, Izuku himself especially so. (Rating subject to change)

Hisashi Midoriya runs a business capturing—and experimenting—on magical creatures. Both his little brother and his wife ran away after discovering his unethical business practices, so he's very protective of his precious son Izuku. But after Izuku develops a rebellious streak of his own, he starts thinking about how to turn him into something easier to contain and control.

In which One for All versus All for One has been a family feud for a very, very long time. (And All for One is running out of bank vaults.)

All Might is the reincarnation of All for One's younger brother. It changes nothing and everything.

After the sludge incident, Izuku Midoriya's dream was officially crushed. However, a later experience takes the boy in a new direction. Izuku had never really contemplated being a detective, but his whole life he'd only ever wanted to help people with a smile on his face. Thanks to some luck and an entire police station, Izuku's dream is reborn.

After discovering Izuku is quirk-less, Inko decides to act in pursuit of helping her son become a hero. Lacking power Izuku moves to the newly formed and budding Academy City and its revolutionary Esper Program. Now eighteen and the most powerful esper in the world, Izuku must fulfill his mission without revealing himself as being Academy City's strongest asset.

When Izuku shattered, Katsuki tried to put him back together. One-shot.

Izuku flinched as the door opened, expecting one of the interrogators. Aizawa walked in, instead. Somehow, this was worse.

The USJ was almost a tragedy, but in the end, there were no fatalities. But what if there were? What will happen to 1-A if people died at the USJ? How will the students of 1-A handle it? What will the fallout be?

Deku is the USJ Nomu, but he hasn't been broken completely. He's still here.

Shortly after Hisashi comes into his reign of power as All for One, he locks his brother away "for his own good." At first he dismisses it as loneliness when his little brother starts talking to himself, but then he glimpses the ghost of a green-haired child. A hundred years later, he sees the same face on his own son. And he realizes what that means.

When the UA school board decides to fire Aizawa for his two consecutive failures to protect the students, Nezu feels like he's fighting a losing battle. And because he doesn't want to lose the best teacher he's ever hired, he does the only thing he can: he takes it to the students. Needless to say, all hell breaks loose. After all, Aizawa wasn't the best teacher for nothing.

Izuku and Mirio have bonded quite a bit, as heroes, over Eri, as students, and as Senpai and Kouhai. So it only makes sense that two people so close would hop online and have a little chat on a rare, free, lazy Sunday afternoon... About the people they've slept with. (Chatfic, Crack-ish, Izuku and Mirio are Fuckbois and bros Yuuyu x Neijre x Mirio Tsuyu x Ochako x Izuku)

They called me useless, worthless, quirkless. I'll show the world what a quirkless freak can do. I'll bring this society to its knees. Villain Izuku with Doc Oc tentacles. Crazy I know. Give it a chance. First in my one shot series.

Quirkless children have been going missing along the coastlines, while some countries turned a blind eye to such events now it has reached the shores of Japan, and with a large string of sudden kidnappings to many to simply ignore something needs to be done. Within the ruins of the once golden city on the seafloor, someone stirs back to life. As Daddy's Home (MHA X Bioshock xover)

When newborn phoenix Izuku rises from his ashes, All for One tells him that he's the reincarnation of his younger brother. At first, Izuku is delighted to have a family. Then he starts to find warnings from the past eight incarnations scattered around All for One's nest.

Izuku Midoriya is a perfectly normal quirkless boy. A good kid who wants to become a hero so he can help people. Also, Izuku Midoriya is an eldritch abomination, and those who stare too long into his eyes tend to go insane.

There is a monster in the Musutafu city forest. This, the locals know. Enter the forest and you will never return. This, they claim.

Midoriya Hisashi is a clone of One for All's first user. Years later, All for One discovers his reborn brother and attempts to smuggle himself into the Midoriya family as their long-lost relative. He only wants to pretend to be a normal person and bond with his adorable nephew, Izuku. Unfortunately, he's not as good at acting normal as he believes.

"I'll do anything for this wish!" "Are you sure?" "Yes." Izuku has a Quirk that makes people flock to him, because they were blinded by greed, by what he could give with his Quirk. However, little do they know that there was more than meets the eye to his Quirk, let alone what he was going to do with it. As the saying goes: Be Careful What You Wish For.

The Vigilante that is Eri had always wanted to meet and speak with the Pro Hero Uravity, A.K.A Uraraka Ochaco. There is something that she wishes to tell her. One Shot. Eri is of the same age as Izuku.

Midoriya was told he couldn't be a hero by All Might, so he decided he would ask every other hero if he could be one. He has finally come to All Might's former sidekick. Will Sir Nighteye be of a different opinion?

It's 1941 and the world is in the throes of war. Izuku Midoriya wants to do his part and join America's armed forces, but the military rejects him because of his small and weak stature. Finally Izuku gets his chance to prove himself when he is accepted into an experimental program led by Dr. Erskine. In which turns him into the First Avenger: Captain America! (Under Reconstruction)

One night after the class graduates their first year and becomes Class 2-A, one Yaoyorozu Momo is out on a patrol and encounters the villain known as Shadow Swimmer, who has a transformation-type Quirk. Thus, Momo is thrown into a world of milky shenanigans and transformation nonsense.

Izuku Midoriya discovers another weird thing about One For All when he finds a strange girl asleep on his chest one morning. Nana Shimura is back from the dead, and also a very hot girl his age who literally can't stay out of his head. Yeah, he doesn't know what the hell is going on either. (Crossposted from Archive Of Our Own.)

He looks up, green eyes sparking with glee as a smile splits his face. "Miss Uravity." He greets, "I hope you didn't mind me paying for your coffee, I know pulling a stakeout on someone like me can be exhausting." Or She knows she's in trouble when the villain she's staking out buys her coffee and has it waiting for her when she walks in.

Izuko Midoriya's year-long rampage ends with capture by All Might. The world does not expect him to speak on her behalf in front of the court. He broke her heart when he told her she could never be a hero, and now he has to find a way to mend it. Fortunately, he does have quite a bit of help from a punk rock heroine. Fem!Izuku/Villain!Deku x Jirou Kyoka

Midoriya Izuku never went to UA and Bakugou Katsuki is now the designated Problem Kid of the class. If Aizawa Shouta plays his cards right, the upcoming U.S.J. training should prove to be a good development for the kid. If all goes according to plan, the activity should push Bakugou to finally see his classmates as his equals. If all goes according to plan.

Izuku Midoriya. The Dawnbringer. The First. The Greatest. To protect those he loved, he made the ultimate sacrifice. Now two centuries later, he is brought back into the world he doesn't recognize. The world he must save once again. This time, from itself.

Most of the time, Shouta Aizawa knew how to correctly handle his trouble-magnet students. Most of the time. One particular Problem Child tested his patience/After a visit to an amusement park, Class 1-A realizes one of them hadn't come home the same.

Izuku's memory was heavy. It felt like he'd been asleep for a very long time even though he was fairly certain that he'd just met All Might on a rooftop. They said that he was a student at UA High School and that he'd been hit with a memory erasure quirk, but that couldn't be right?

When Corona Virus forces 1-A into an online classroom for a period of time, Aizawa is annoyed. But when his number one Problem Child starts wearing makeup and flinching at movement, he becomes concerned. Izuku just wishes that his father never came home in the first place.

Midoriya is hit with a quirk that separates him into his core emotions, and a lot more horrifying truths about his past is being revealed way earlier than he would have liked. The concept of this quirk is inspired off that KiriBaku comic by @venadorosas on Twitter Note: This fic isn't exactly canon to Worthless Necessity, and it takes place after Chapter 96 but before Chapter 97.

Aizawa has to help Yaoyorozu recover from learning the hardest lesson: sometimes you just can't save someone.

Without the Symbol of Peace, previously dormant villains are now on the rise, including a notorious quirk trafficking ring. Determined to track them down before any more kids go missing, Eraserhead runs into an unfortunately familiar face. Parental!Aizawa.

It's Aizawa's favorite day of the year. The day he gets to lay back, relax, and drink in his student's tears.

I was watching episode 8 (where Izuku admits to Bakugo that his Quirk isn't really his), and I thought to myself, "What if Aizawa overheard that conversation?" So here we are. Just a little oneshot on his thoughts and reaction, but if you want more, I might consider it.

Aizawa could tolerate the hero worship, as long as none of them tried to hug him.

Midoriya, depressed and bullied by his peers, wanted a quirk to be a hero more desperately than anything else. He wanted it so bad he accepted to be a human volunteer to an experiment. Finally, Midoriya has a quirk. "Engineered quirk: Unstable Biomass." With it, he can absorb things and transform his body. But will it be enough?(Prototype inspired) Prequel to Deku The Prototype pro

After a series of failures, Momo's desperation leads her to seek help from the Demonic Monster of the Support Course the Third Year Izuku Midoriya! Tall quirkless badass Izuku that don't need no quirk. IzuMomo

Izuku Midoriya grew up with two major voids in his life: his lack of a quirk and his lack of a father. When both of those voids are finally filled, how will Deku react when his father wanders back into his life? Even worse, how will he react when he learns his father is the infamous villain named Arson?

"You know, if you really wanna be a hero that badly, there actually might be another way. Just pray that you'll be born with a quirk in your next life. Then take a swan dive of the roof of the building." "Oh, okay" he whispered. One shot.

Present Mic has a casual conversation with his fellow teachers about wheather or not any of the students will end up together at some point. Fair enough...if no one else could hear them. That is, unfortunately, not the case.

After being bullied by Bakugo Izuku is walking home when he notices a strange shop that was not there before. The nice Oldman at the counter offers to give our quirkless boy one item from the store for free. Watch as Izuku browses the shop's wares.

Of all the calls Yagi Toshinori had expected to receive today, this was easily one of the very last. "I'm uld you repeat that." He asked, just to confirm what he had been told. "Izuku Midoriya has been arrested for assault and illegal quirk use. He has already admitted to being the perpetrator. We couldn't contact his mother and you were his next emergency contact."

He spent the holiday's alone just him and his cats, something his students would change this time of year.

A simple injury leads Aizawa to learn about Izuku's struggles. Parental!Aizawa. Warnings: Implied/Referenced Self-Harm.

Katsuki was right. All he had to do to get his quirk was jump. But it's never as simple as that. (Ghost!Izuku) (Guilty!Bakugo)

This is the first part of the story of the 10,000 year reign of the Overlord Ainz Ooal Gown.

[Insane!Midoriya AU] He snapped. He snapped and no one knows how to handle what they're seeing. The strongest among them is currently being beaten to death, and no one can lift a finger to stop it. What's worse, is that they're next.

Ochaco had always wanted a pet, and she finally got one. She just never thought it'd be like this. She had to admit, Izuku was cute, and even more so in dog form. When two teens bump into a child with a weird Quirk, class 1-A is in for a surprise. "So Bakugo and Midoriya are…" "Yeah. They're dogs." Just a bunch of friends dealing with Deku and Bakugo as cute dogs.
