Do you have any headcanons about how Toshinori interacts with the 1-A girls? (Like Ochako? Bonus sketches by Horikoshi imply the kid skips meals and didn't use the heat/ac as much to save money. I can't help hoping All Might or Eraserhead noticed after she moved into the dorms)

- With the time All Might spent abroad as a hero, I imagine he picked up tastes in a wide array of music genres.  I could see him giving Jirou recommendations.

- Similar thing with Yaoyorozu and food.  She may have had some exposure to wider cuisines given her family’s wealth, But All Might could encourage her to explore options that don’t fit the typical perception of gourmet.

- Speaking of food, he put together a meal plan similar to Izuku’s for Uraraka when she moved into the dorms.  He makes sure everything is affordable, but when he makes something for her he promises he has more money than he knows what to do with and she doesn’t need to pay him back.

- When he’s around and Mina is playing music, she tries to get him to join in on the dancing.  He of course is terrible, but in that fun bad dad dance sort of way.

- Tsuyu is a fairly quiet person in her down time, preferring to read something.  The background noise of the common room actually helps her focus.  All Might sits with her when there’s no one else around.  They don’t usually talk, but she appreciates the company.

- Hagakure is always looking for new ways to stand out as a hero in spite of her invisibility.  All Might shares what research he has on historical and international heroes with similar quirks, as well as recommend her stories of fictional heroes to help inspire her.

Can I ask for your HCs...on a Dadmight scenario, bio dad au or otherwise, where he has to kill a villain to protect Izuku.

- All Might and Izuku head back to school from visiting his mother for dinner.  It’s after dark and starting to rain.  The train station isn’t far from school, so they walk.

- The rain gets harder.  They try to take a short cut through an alley near a construction sight.

- A villain jumps them.  He’s a small-timer; someone who would normally be short work for Izuku.  But he catches them by surprise.  A force quirk knocks All Might onto the ground and Izuku into a wall.    

- All Might is dazed a moment.  He blinks up to see the villain pinning his boy, whose head is bleeding and is barely conscious, up against the wall.  There’s a syringe at his thoat.  All Might isn’t sure if the man intents to inject something, or steal his successor’s blood.  It doesn’t matter.

- Without One for All, All Might doesn’t stand much of a chance in a fight.  Unarmed that is.  He grabs a metal pipe from a pile in the construction site, and takes advantage of the same ambush strategy as the villain.  He doesn’t think.  He just sends the man off his feet with a blow to the head.

- Izuku slumps to the ground.  He doesn’t respond to All Might’s calls.  He drops the pipe, scoops up his boy, and runs.  UA isn’t far.  He calls Recovery Girl on the way to be ready.  The rain comes down harder.

- The villain was attempting a kidnapping.  Izuku was injected with a sedative.  It isn’t a strong one, but the fact it came from an unknown source and used by a villain are reason enough to be concerned it could be laced with something worse.  The wound on his head is superficial.  Izuku stays in the infirmary all night for observation.  All Might stays with him.  

- They call the police.  All Might gives his testimony about what he saw, Recovery Girl about Izuku’s blood work.  He’s honest about striking the man with the pipe, but the police say the situation falls comfortably under self defense.  Not to mention that despite being retired, his hero license hasn’t expired yet.  The police find the syringe at the scene, but not the villain.

- All Might doesn’t relax until Izuku wakes up.  He doesn’t remember what happened.  Hugs and explanations are gives.  Izuku apologizes for not paying attention, and thanks All Might for saving him again.  All Might just hugs him again.

- Things go back to normal until three days later, when news breaks that a body has been discovered.  An adult man with no identification and a severe head injury lying face-down under a bridge less than a mile from UA.  He drowned.   The news article speculates that the man sought shelter from the rain, but passed out or was otherwise unable to move when the water rose due to his injury.  Murder is never suggested.

- All Might knows.  He expects a call, from the police or the news or someone.  But it never comes.  Do they genuinely not suspect anything, or are they actively covering up his involvement?  None of his colleague bring up the news.  Maybe they didn’t see it.  The most he gets is Nezu sending an email suggesting increase patrols for the week.  And all the others know about that night is that there was an altercation, not the details of how it was stopped.  All day, he expects someone to be waiting around the corner to pull him aside to tell him he’s a murderer and can’t teach anymore.

- All Might has never directly killed anyone before.  It’s not like he wants to shout it from the rooftops, but he still feels like he should take responsibility.  But he was a villain!  he was trying to kidnap his boy!  

- Speaking of his boy, Izuku has no idea...

[aconstantstateofbladerunner]

Believe it or not I'm kind of starved for dadmight rn (I've stormed that tag like a well seasoned soldier); just spew any cute or painful ideas you got lol I'm not picky

Random soft moments of that adoption au i wrote about a few days ago.

- Izuku’s favorite thing about having a dad is getting hugs and kisses.  Toshinori always gives him a kiss on the forehead, top of his head, or cheek before he goes to school or bed.  And he just hugs him all the time, sometimes so much he picks him off the ground.  They’re little things, but Izuku never thought about them before he was adopted.

- Sometimes pretends to fall asleep on the couch just so Toshinori will carry him to bed.

- Toshinori buys Izuku whatever he wants.  Money isn’t an issue and seeing his boy’s face light up is just an indescribable feeling.  Izuku only asks for small practical things at first, like a notebook or maybe some nice socks.  It slowly escalates to things he wanted but could never have before, like decorations for his room and stuffed animals.  The first particularly bold request is a leather jacket with shoulder spikes.  All Might buys it with a smile on his face.

- The one thing All Might won’t let him get is a pet.  As a hero, he moves around and is generally out of the house a lot and Izuku will soon be the same once UA starts.  Not fair to an animal to be alone most of the time.  The compromise is regular trips to animal cafes and parks.

- Izuku still gets One for All, but this time Toshinori takes him to his agency’s private gym in addition to cleaning the beach to work on specific techniques.  He was willing to pull Izuku away from the trash beach entirely, but Izuku insists on finishing the job.  Along with machines and equipment for lifting, there’s a gymnastics floor.  This is important because every training session ends with the two of them jumping into the foam pit.

- All Might having a son is more speculation and rumor than confirmed fact.  Yes All Might was connected to a big story involving social workers abusing foster kids, but most reports his involvement ended with him testifying about the victim’s state in court.  More obsessive fans have noticed his fewer fights.  Some have gone so far as to post pictures of a random tall blond guy with a kid about the town and claim it’s All Might.  Casual fans have deemed it a reach.  Izuku shows All Might the forums, and they both make new accounts to post even crazier theories and get in fake fights with one another.

[aconstantstateofbladerunner]

Ok but jumping off in that person mentioning Izuku losing your arm, do you have any headcanons for amputee Izuku. Especially in relation to dad might and eraser head. With the assumption that it wasn’t izuku’s fault it happened. (An unavoidable accident as opposed to him being self destructive with his quirk.)

Okay I’ve been sitting on this one a while, largely because I have something planned for a fic and i wanted to come up with something different for this ask.  I think this works out.  That being said, I did fuck all to research how actual amputations work because there is enough medical-related trauma going on right now and I don’t wanna deal with that.

- So I see him fighting a villain with some sort of toxic quick, specifically a sting of some kind that causes rapid onset infection.  It doesn’t even hurt as bad as a bee sting, so Izuku doesn’t think much of it when he gets hit above his wrist.  There isn’t even a noticeable tear in his costume.  He beats the villain without much trouble.  His arm is a little sore during paperwork, but that’s close enough to normal.

- But the soreness persists through to the end of the day, gradually getting worse.  Izuku finally takes of his glove, and his whole arm is an angry red.  

- Let’s say Aizawa was in charge of whatever field thing he was doing, and they haven’t gone back to UA yet.  Izuku shows him his arm, and innocently asks if he think’s it’s worth going to Revovery Girl over.  He takes him straight to a hospital.

- The doctors confirm what Aizawa suspected: Izuku’s arm is in the early stages of infection.  They give him some antibiotics and wrap his arm with salve and bandages.  They also insist he stay overnight for observation since it seems to be over a large area.  But the general consensus is he should be fine since they caught it early.  Izuku is sad he can’t go back to the dorms and a bit embarrassed he got hurt again, but Aizawa chides that for once it isn’t his fault.

- It’s late so Izuku goes to sleep soon after.  Aizawa stays nearby.  He calls the school and All Might to explain the situation, the latter of which insists on heading down there himself.  In the meantime, Aizawa looks up the villain’s profile for details on his quirk.  There aren’t any really, but at least three murders are attributed to him.  The otherwise healthy victims when into sudden septic shock.  They all died less than 24 hours after encountering the villain.  Aizawa brings this info to the doctors immediately.

- All Might arrives just as they head back into izuku’s room to check on him.  He’s already worse.  He’s red and sweating from a fever, panting through a restless sleep.  A nurse cuts open his bandages to reveal massive festering green and grey spots of skin all up his arm.  The call is quick.  They have to amputate.  

- The doctors and surgeons take Izuku back.  Aizawa and All Might call Inko.  It’s almost three in the morning when she arrives, already crying.  They waited to give her the details in person.  For hours, all three look over pamphlets about the recovery process and resources on therapy and prosthetics.  Izuku would loose his dominant hand, which would most certainly set back his writing somewhat, there were more than enough examples of amputee heroes who continued their careers.  All Might tries to rationalize that Izuku has had a lot of practice writing with his other hand since he broke his arm so much.  No one finds comfort in that.

- Izuku wakes up late the next morning, delirious and numb.  He doesn’t quite remember what happened.  All Might is right there, and he gently puts his hand on his shoulders to keep him from sitting up, then caresses his cheek so he’s facing him.  It’s comforting.  He smiles, and turns over to hold his hand.  But his arm won’t move.  All Might stammers out a quick preamble, but nothing could have really prepared him to turn to a stub where his arm was just yesterday.

- “Just yesterday,” is the phrase he keeps repeating in his head.  Through all the doctors’ explanations and his mother’s tears, he thinks about just yesterday.  He had an arm yesterday, now he didn’t.  He went to sleep just a little sore, thinking a hospital stay was overblown when he felt fine, and woke up to one of his limbs gone.  He didn’t even have a chance to process it.  Processing is all he does the few more days they keep him in the hospital.  Everyone assures him that things can go back to normal eventually.  Dozens of heroes went on to have long, successful careers after limb amputations.  There’s even a program in place that provides heroes with high-quality, quirk-compliant prosthetics at a fraction of market price.  Everything will be okay.  Just yesterday, everything was.

- Izuku’s emotions take a break for those few days.  Like the space where his arm used to be, he feels numb.  Part of him can’t shake that it’s his fault.  He did something wrong in that fight and it cost him.  Everyone say’s he didn’t, that he did everything right and this whole thing was just an unfortunate accident.  He doesn’t cry at first.  His mom cries a lot.  All Might cries a little.  Even Aizawa gets a little choked up as he promises to help him through this.  But Izuku doesn’t cry.

- He doesn’t cry until it’s time to go home.  School gave him another few days off to recover at home with his mom.  Aizawa said his classmates know what happened and will want to check up on him if he’s up for it.  All Might says his mom agreed to help take care of him.  Then Izuku breaks down.  Suddenly, it’s all real.  His arm is gone forever and he has to deal with that for the rest of his life.  He’ll have to face his friends, and later the world, with a piece of himself literally missing.  He went to bed and woke up missing one of his arms.  It’s not fair.  Mom and All Might hug him, and Aizawa holds his remaining hand.  Rational thought and determination to overcome this new challenge return in due time, but they have to wait for the hurt and scared child to work out his delayed feelings first.

[aconstantstateofbladerunner]

Have any dadmight headcanons to spare?

I’m gonna take this opportunity to write out an au idea I’ve had for a while, but will probably never turn into a full fic for various reasons.

- So the main idea is that Izuku is an orphan.  His mother died in a freak accident and his father surrendered him when he was a baby.  Foster care is all he’s known.

- The people running the branch of social service he’s a part of like to cut corners, and where better to do that than with the quirkless kid?  They use him like a test dummy by sending him to new foster homes with some questionable elements to see if they’re safe for other kids, leading to some very bad encounters.  Those that aren’t outright abusive say things behind his back.  

- All Might, meanwhile, has been going back and forth on whether or not he wants for a few decades now.  He’s considered adopting, giving a child similar support and care Nana gave to him, but worries about the implications of having the Symbol of Peace for a parent.

- That changes after the sludge villain attack.  I actually have two ideas for how it could go differently.  

- 1) The villain hurts Izuku much more seriously than canon, so All Might takes him to the hospital.  Izuku is unconscious, and doesn’t have a phone or any clear contact information for guardians, so the authorities just put word out that a 14yo boy was rescued and taken in for medical treatment.  All Might offers to stay with the boy until his family comes to get him.  Nobody comes.

- 2) The villain attacks a group of foster kids including Izuku.  The event is highly publicized, with All Might encouraging people looking to become parents to consider adopting one of the orphans he saved.  Everyone gets offers right up until the point word gets out that Izuku is quirkless, at which point all the prospective parents back out.

- Either way, All Might realizes that no one else is going to take him.

- Leading up to moving in, Izuku is convinced All Might only adopted him out of pity.  He believes at best he’ll just be a pet or project All Might throws money at to keep alive, and nothing else.  At worst, he’s a publicity stunt.  A prop for the press to take pictures of.  Izuku doesn’t want to believe his idol is that sort of person, but why else would he even bother with Izuku?

- His perception changes slowly over the course of that first day.  

- When he walks out the door to where All Might is waiting to sign the final paperwork, the man looks at him with such genuine kindness and love, Izuku can’t help but break down.  No one has ever looked at him that way.  All Might opens his arms, and Izuku falls into them.  He feels safe for the first time in a long time.

- Izuku comes to his senses in the car.  He probably just embarrassed himself in front of the greatest hero ever.  But the man doesn’t comment on in.  Instead, he hands him his phone plugged into the car speakers, and declares he’s in charge of the music for the long drive home.  Home, he thinks.

- The afternoon is a blur.  Izuku is feeling every emotion at once, and yet nothing at all as All Might shows him around his home.  He gets a clearer head about an hour after his new caretaker left him alone in his room to get settled in.  

- Then, he’s called for dinner.  It’s katsudon.  All Might made it from scratch.  “You never mentioned what you like, but this is one of my favorite comfort foods.  A home-cooked meal for your first night home.  I hope you like it!”  Izuku takes one bite, and bursts into tears.  It’s the best thing he’s ever had.  Not just because it’s miles apart from the scraps and takeout he’s eaten all his life, but because his dad made it.  He’s home.

[aconstantstateofbladerunner]

Do you have any particular headcanons about Nana's interactions with Toshinori when he was young?

- Neither Toshi nor Nana were particularly good cooks, when they could usually manage something decent when they worked together.  But more often than not they ate at food stands or small hole in the wall restaurants that gave a discount after Nana saved the owner one time.

- Toshi was a big fan of classic prequirk fictional superheroes, Nana not so much.  He tried to get her into them by loaning his comic books and talking her into a movie night.  She humored him for the most part.  The only movie she really got into was the 1978 Superman movie.

- The hero system was less formal back in Nana’s prime.  Agencies with armies of sidekicks were around, but weren’t yet the standard.  Nana didn’t have any sidekicks, but she was a respected figure in the local hero community and often gave advice to those just starting out.  Toshi was her only full-time apprentice.

- The less formal hero system also meant Nana never saw anywhere near the financial returns All Might, or even the average modern hero, would get later.  She survived mostly on donations from grateful people she helped and taking odd jobs that involved helping out the community.

- Nana planned to tell Toshi about the more spiritual aspects of One for All when he was ready.  It’s not easy to casually bring up “hey you might get dreams and advice from dead people” in a casual conversation.  Especially when the person you’re talking to has no point of reference.  But she did talk a lot about it with Gran.  Just in case.

[aconstantstateofbladerunner]

I send a prompt ask: One time Izuku was SoftTM, one time Izuku was FeralTM.

This is incredibly unbalanced.

Soft:

Eri has made this trip to the bakery before, just with more people.  (And there are still more people with Aizawa and Mic following close behind in disguise, but she doesn’t know that.)  The idea is to get her used to public spaces without becoming too codependent on Aizawa.  But they did give her a choice, and she chose Izuku.

He was almost as nervous as she was.  Being one of the only people a little kid trusts, and the threat of expulsion should he fail, was a lot to worry about.  So he held her hand the entire walk up the road.  It was a busy, crowded day, so she stuck like glue.  The further they got into town, the denser the foot traffic, and the more Eri seemed to look around nervously.  Izuku decided she needed a distraction.

“Hey, Eri.”  She looked up at him, bordering on tears.  “Grab my hand with both hands.  Really tight.”  Confused, she did so.  Careful as he could, Izuku lifted her off the ground as he stepped forward, swinging her slightly.  “How was that?”

“...  Again.”

And he did.  He swung her alongside him as he walked all the rest of the way to the bakery.  And back.  She smiled the whole time.

Feral:

They caught him on a bad day.  The class does a joint training excessive with another hero school; taking turns battling one another in small groups while the hero team tries to save hostages from the villain team.  For whatever reason, they are more openly hostile to quirkless people.  Maybe it starts as an off-color joke, but eventually some of them start comparing the training dummies they use for rescue practice to quirkless people, and how useless they are.  One says if he were a villain, he wouldon’t bother holding quirkless people alive.  He’s says the alternation would be mercy killing.  Izuku is clearly uncomfortable, but stays quiet.  While he waits for his turn, he stands as far from the other class as he can without making eye contact.  Some of them recognize him from the sports festival and try to talk, but he gives short answers that shit down the conversation quick.

That changes when they bring up All Might.  They say it would have been better if he died.  Living quirkless is beyond shameful, and they can’t look at him the same anymore.  Izuku has had enough.  He volunteers to go next, and challenges the commenters to do the same.

And he destroys them.  The rest of Izuku’s team hasn’t seen him like this before, but no one objects to his plan: drive the enemy into a bottleneck where he’ll be waiting.  The terrain provides a lot of cover and shadows that he takes full advantage of.  He picks off one half of a pair by grabbing one from behind.  Their mouth is covered before they can scream for help, not that they would have had long to do so anyway.  Izuku is efficient.  No one sees him coming.  No one has the raw strength to compete.  

The rival team emerges from the loss, bloody and exhausted, but impressed.  What sort of crazy stealth quirk does that kid have?  Their teacher berates them for losing to someone who didn’t even use their quirk.  They turn to Izuku in cold shock.  He doesn’t look back.

Wolrdbuilding hcs?

On this episode: how would quirks affect art?

- A painter who can see the full spectrum of light and creates works that naturally incorporate such elements.  Eventually they team up with someone who can temporarily grant others such vision so they can truly experience what they’ve made.

- A singer with unique vocal cords who can generate sounds that no one has ever heard before or recreate.

- A performance artist with an emotional manipulation quirk or the like (quicks that are highly stigmatized) invites spectators to enter their influence only for a moment, and observe their reaction after.

- Entirely new genres of dance sprout after specific quirks.  The inhumanly flexible test their body’s limits to music.  Illusionists put on breathtaking shows that can only be viewed in person.  Heavily mutated bodies develop new languages of movement to express their specific experiences.

- I was reading some old DC comics where Superman and some pals traveled to a planet of sorcerers that created mountains of color and build cities on the backs of frozen waves just because they could.  I’d like to thing there are some crazy architects and artists with zero gravity or some kind of construction quirks just going absolute ham fucking with physics and building great works of art that would have been impossible to build conventionally.

[aconstantstateofbladerunner]

Do you have any random Iida headcanons?

- Iida is one of those people who when he finds a piece of clothing he likes will buy a bunch of that same kind.

- Good at subjects with structured assignments like math and science, struggles sometimes with more open-ended and interpretive things like literary analysis and history.

- Secretly really wants a dog.  Thought it was too rude to ask his folks when he was younger and now that he lives at the dorms the point is mute.

- Since orange juice is his fuel, Izuku asked if other orange-based products can work too.  Iida didn’t know.  This launched into a joint project where they measure his performance after orange popsicles, ice cream, different brands of juice, and just straight eating oranges.

- This isn’t a headcanon but remember when he straight up ripped off his own exhaust pipes so they would grow back stronger?  What did he do with the old ones?

[aconstantstateofbladerunner]

Pray tell, do you perhaps have any Dad Might headcanons you might like to share with us this evening?

Just some random stuff.

- People send Toshinori lots of things like T-shirts as product samples or as just fanmail.  Most of it doesn’t fit him, so he gives it to Izuku.

- Toshinori is the only one allowed to try and mess with Izuku’s hair.  He doesn’t like most people touching him anyway, but around his head he’s especially sensitive.  Even his mom can’t do much.  But Toshinori is gentle and doesn’t try and fight him to get his hair under control for public appearances.  He was so relaxed one while Toshi was combing his hair he almost fell asleep.

- Izuku does fall asleep on the bus ride back from some All-day event with the class.  Someone takes a video of All Might carrying Izuku inside that goes viral.

- Toshinori will find random pics of fluffy animals to send to Izuku saying “it’s you!”

- Toshinori has a big comfy reclining chair in the common room.  It’s so huge four of his skeletal self could sit together comfortably.  Izuku’s Designated Spot for movie nights and such is right next to him in that recliner.  Toshi usually brings a blanket for them to share.  It’s the coziest thing ever.

[aconstantstateofbladerunner]

hc of all might w preemie izuku?

Written generic but these could also apply to Angel’s Egg, and maybe Two Sons in the Sunset.

- He’s tiny.

- Seriously he's just so small.  Izuku’s head is maybe half the width of Toshinori’s palm, and his whole body fits snuggly in one hand.  Even though he’s a giant, Toshinori still knows that’s way too little.  He takes him to the hospital right away.

- The nurses take Izuku back right away.  Meanwhile, Toshinori is questioned as to why he, a single man, is bringing in a tiny premature newborn.  He explains himself, making no effort to hide how anxious he is to get back to Izuku.  His story checks out (being the number one hero certainly helps) and they take him to see him.

- Izuku is only just two pounds.  He’s practically swimming in wires and tubes inside an incubator that makes him look that much smaller.  One tube is shoved down his throat.  Toshi wells up after just one look.  Someone asks where Izuku’s name comes from if he’s an orphan.  Toshi says he’s no orphan, then asks how he has to talk to to make that official.

- Slowly but surely, the tubes and wires start to be taken away.  Toshi’s heart is pounding when a nurse says they’re going to try bottle feeding.  She shows him how to properly hold him, and everything goes well.  After Izuku rests his tiny cheek on his father’s exposed collarbone.  Toshi nearly cries again, brushing thin locks of the baby’s hair with his thumb.  They sit there for a while, absorbing one another’s warmth, as long as the staff let them.

[aconstantstateofbladerunner]

Any dad might angst or hurt/comfort head canons with izuku being the one in need?

My dude I’ve been working the most dad might chapters of Butterfly the well is almost dry but here goes:

- The rumors/jokes about Izuku being All Might’s son grow beyond UA.  A couple hero analysis forums Izuku follows pick up the idea and run with it.  He stays up all night reading them and the comments.  He’s embarrassed, but not too concerned since they’re pretty obscure forums that not many people read.  He’s fine.

- While he’s not paying attention, the idea picks up steam.  Larger hero blogs start writing think pieces that get shared all over social media.  Izuku doesn’t notice until he’s watching the news with some of the others and they run a story on him.  And he panics.

- More attention means more opposition.  A lot of people aren’t too enthused about All Might having a secret son.  He’s supposed to be untouchable; what if a scandal like this ruins his image?  Certain fans are bitter All Might having a kid messes with their self-insert adoption fics.

- And that’s not even getting into people who have a problem with Izuku specifically.  He gets every insult under the sun: he’s too small and childish, frumpy, ugly freckles, a twig, doesn’t look enough like All Might.  His own quirk breaks his bones.  Every other picture that comes up shows him crying.  He is a disgrace to his father.  It brings him back to a place before UA.

- Izuku suffers in silence.  The rumor is old new to the UA students so they don’t pay attention.  Teachers don’t pay much attention to what random on the internet say about their students.  All Might himself doesn’t use social media.  Izuku knows that speaking up won’t make the problem go away.

- All Might doesn’t find out until Izuku breaks down.  They’re training one on one, and Izuku seems frustrated by something.  His moves are off, and he doesn’t accept All Might’s criticism with his usual smile and promise to get it next time.  Instead he mumbles an apology and won’t make eye contact.  In an attempt to lighten the mood, All Might makes some innocuous comment about Izuku’s freckles.  “Don’t cry or you’ll wash them away.”  And suddenly Izuku cries.  He tries to ask his student what’s wrong, but he runs away.

- He finds him a few hours later curled up under a tree at the edge of campus.  After a few more tears, he gets a clear answer.  All Might’s first instinct is to say that what people say online doesn’t matter, and that this is something Izuku is going to have to get used to as a hero.  But first, he looks up what people are actually saying.  It’s way over the line, and he has to do something about it.  But first, he leads Izuku back to the teacher dorms, and lets him let out all his feelings where the others won’t see him.

- All Might releases a statement denying the rumors, but adding “To have Young Midoriya as my son would be an honor and privilege I don’t think I could ever find myself worthy of.  He’s a fine young man, and will more than likely be one of his generation’s greatest heroes.  Do not let the people who have belittled him get away with changing their tune to jump the bandwagon.  I certainly won’t.” 

[aconstantstateofbladerunner]

Any more midoryia headcanons?

- Idiot savant at video games.  He doesn’t play them much or even really enjoy them, but when the others rope him into an Injustice tournament, he gets pretty far despite having never touched the game.

- Isn’t great at cooking many things, but those few things he can make he does better than anyone.

- writes letters back and forth with Eri, even though they see each other most days.  One of the children’s books used to help her learn to read and wrote featured friends writing letters, and she wanted to do it too.

- He loves to spar with the others.  Training is his bread and butter, so he’s down for a throw down whenever.  Some upperclassmen wanted to take advantage of his willingness to fight as an excuse to beat him up, but he wiped the flow with them without batting an eye.

- Izuku and his friends like to take one another to cool/special places they like on their days off.  But when it’s his turn, Izuku just takes them to a park he went to when he was younger, not his favorite place.  He felt weird taking them to Degoba Beach.  That’s his and All Might’s place.

[aconstantstateofbladerunner]

Okay, so, a new Quirk of Izuku's manifests (idk how, it doesn't actually have to be a Dramatic Moment for the situation to work-- and he just has to have the right general *feeling* or thought to trigger it, right?) And by complete coincidence, no relation to anything else-- it's Fire Breath. What happens in the aftermath of discovering that Quirk? Either with or without his class and Aizawa being In On It by that point.

- By the time this happens, everyone has accepted Izuku has weird multiple quirks, even if they don’t know about One for All.  Aizawa, who does know, is just relieved fire breath is a relatively conventional quirk compared to some of the weird stuff he’s been getting.  Toshinori has similar thoughts.  Izuku, meanwhile, is horrified.

- Izuku didn’t hurt himself or anyone else when it manifested.  He sneezed fire while walking alone between training zones.  So why does he seem more freaked out than normal?

- Bakugou is the one who tells Toshinori to confront him about it, but says no more.  He’s not sure of something himself, and wants to sit this one out.  When Toshinori finally gets Izuku alone to talk, he immediately breaks down.

- The quirk didn’t come with a vision from a previous holder.  Toshi’s notes are incomplete but there’s no mention of fire breath.  But Izuku’s father could.  What if the new quirk is his actual biological one?  One with nothing to do with One for All?  One that’s he’s had all this time and just never showed itself?

- Neither know how to find the answer, nor what to do with the potential results.

Can you give me more oblivious Toshinori says or does something that further cements the Dadmight rumor in the UA teachers' minds (except Aizawa who you've mentioned in other asks has figured out they're too awkward and formal to be related - except maybe he has doubts sometimes that maybe they just recently met and that accounts for the distance)?

- Whenever one of the other teachers mentions an interesting piece of hero news or research, All Might asks them to send it to him so he can send it to Izuku.

- Once Izuku got more comfortable with casual touching, All Might got in the habit of that parent thing where he keeps trying to fix his appearance.  Brushing out a ringleader is his uniform, straightening his tie, trying to comb his hair with his hands.  Izuku just lets it happen with mild exasperation.

- All a Might is really bad at hiding his enthusiasm for when Izuku does something cool.  Much like during the Sports Festival, he can’t help but cheer his kid on during training exercises.

- One of the others got him a #1 Dad mug and he didn’t question it at all.

- Aizawa doesn’t particularly care one way or another when it comes to the two being related.  Every major hero has had a version of the “secret child” rumor, All Might especially.  The similar quirks is the only real evidence in his mind.  As boisterous and showy as All Might is, Aizawa can’t imagine that genuinely kind and caring person to up and abandon a potential lover and child.  But then again, he knows from experience that the worst of the worst can hide in plain sight.

When I sent the ask, I kinda hoped you had something on others finding out how Sir treated Izuku. I should've been specific. Sorry. How 'bout if I tell you some of my headcanons instead: All Might knew Sir didn't take too well on Izuku being his successor, but his belittlement was too far. The wedge between them grows. Mirio is devastated & apologizes for not noticing. Ironically the only visitor Sir gets now is Izuku. They're on friendly terms, but Sir wishes it'd happened sooner.

Hey sorry about that!  But your ideas definitely give me something to work with!

- Nighteye is still severely injured, but he survives.  Whether or not he’ll be able to work in the field again is up in the air.  The recovery process is long and slow, but he survives.  And he has more than a few people to talk to in the mean time.

- It’s mostly Mirio and his sidekicks at first, just checking in on him and having regular conversations about work.  Mirio eventually confessed that his quirk was erased in the raid, but Nighteye is unconcerned.  He still sees the vision of his apprentice becoming a great hero, so they just need to give it time.

- All Might visits semi-frequently.  The first thing he does is apologize for being so dismissive of his friend’s concerns for his health.  With hindsight as his guide, he can better explain his motivations.  If Nighteye’s predictions were always right and he was slated to die, than All Might wanted to make the most of the time he had left rather than just sit around somewhere waiting for the end to come.  Nighteye understands, and forgives him.

- They go on to discuss their apprentices.  Nighteye is still a little hurt that All Might didn’t even bother to meet Mirio when looking for a successor.  All Might counters that Nighteye didn’t need to meet Midoriya before outright rejecting him.  The process of finding and passing on One for All is a very personal one, and while All Might appreciated Nighteye’s desire to help, this was a decision only he could make.  Nighteye gets a little indignant, saying that his friend isn’t infalable and he should have asked for a second opinion.  All Might did.  That’s when Nighteye refused to meet Izuku.  The visit ends.

- The next time he comes, they discuss Mirio.  All Might has been speaking with him, and he’s a good kid with a bright future.  Nighteye asks if he would still consider him as a successor.  All Might says that it’s not his decision to make anymore, it’s Izuku’s quirk now.  But Nighteye says that All Might is still the authority, and he can convince Izuku to reconsider, especially since Mirio doesn’t have a quirk anymore.

“And is that why he told me that he doesn’t visit you because you don’t want to see him?  That you don’t like him?  Because you’ve been trying to get him to ‘reconsider?’  Well, it almost worked, because I just came from overhearing Izuku offering his quirk, his dream, to Mirio.  Care to elaborate?”

- The truth comes out.  Nighteye had been putting unfair pressure on Izuku to try and convince him he was unworthy.  All Might breaks down everything wrong with it.  Mirio has something of his own, even if it was hard to control.  Izuku grew up with nothing, surrounded by people who wouldn’t let him forget it.  All Might was the same when he was young, but his master saw his potential and raised him.  Just as he is trying to do with Izuku.  All throughout the internship, he watched the bright and happy boy sink further back into the anxiety and depression he had when the two first met, and refused to say why lest he drive the wedge deeper.  Well, he didn’t have to.  Nighteye did that on his own by being just another bully.  All Might leaves, and doesn’t come back.

- Mirio comes in soon after.  He heard everything, and confronts the teacher he looks up to.  He had no idea how much Midoriya was hurting on his behalf.  He feels used.  Nighteye was just trying to make him into another All Might; he saw blond hair and a big smile and decided that was enough to carry the world.  He didn’t even ask if he wanted it.  He was happy just getting to have a chance.  He didn’t need the person he looked up to most to try and steal someone else’s.  In tears, he leaves too.

- Nighteye is alone in the hospital for a long time.  Some of the sidekicks stop by, but it’s purely business.  The nurses are nice, but not the greatest company. So he has plenty of time to contemplate all the places he went wrong.  Seeing the future does not grant the benefits of hindsight.

- One day, he wakes from a painkiller-induced nap to Midoriya in his hospital room.  He’s in a chair the furthest he can be from Nighteye’s bed, but he’s there.  Nighteye apologizes profusely for everything he put the child through, directly and indirectly.  The boy only hesitates in his response to make sure his elder is done speaking.  Then he forgives him with the most genuine smile the man has ever seen.  And for the first time, he truly comprehends just how wrong he was.

Hope that’s better!  I actually hope to incorporate this into a full fic someday, so thanks for the jumping off point.
