Chapter Text

Izuku has a quirk that when he was born summoned the Shelter from POR including the masters. In this they're just constructs created by space and time.

So when he was born a bright light appeared and so did a key. This key allows access to the shelter. if placed in any door the door will open to the shelter.

This leads to his mother figuring his quirk out by talking to the people inside of the shelter.

After 2 years Inko sets up after talking to the Prime minister, a "Ranger" school

Most of class 1a and some of B + shinso will go

The school can be started at age 6

Info for people who haven't read POR:

Rangers are a group trained to protect the King of Norghania (The books country), unlike soldier Rangers are more stealth based. So like underground heros

In the book at age 15 kids who are related to rangers have a chance to become one. To do so they go to a camp thing for 4 years where they learn the basics

They have to become extremely fit so lots of exercise.

if they make it all 4 years without failing they become rangers, if they wish they can specialize.

There are 4 main houses/groups

Archery, wilderness, expertise, and nature

Archery: Archery, learning how to build and care for a bow, how to throw knives and axes

Wilderness: Trapping, Tracking and Animal care and working with animals

Nature: Medicine, plants, Poison, Chemistry

Expertise: Hand to hand, Stealth, assassination

Everyone in the first 4 years learn from all of them, in the 4th year a test is taken to determine which the person is best suited for, and then for that year they focus more strictly on it

The specializations are learned at the shelter. In the books it was 1 year, here it will be 2

Archery: Natural marksmen, Infallible marksmen, Archer of the wind, Elemental archer, Forest sniper and mage hunter

Wilderness: Beast whisperer(Can deal with wild animals/calm them down, and has a beast companion), Beast master (Knows all the types of animals, and a lot about them), Man hunter (Tracks down people to capture), Tireless tracker, Tireless explorer

Nature: Healer guard, Elemental fletcher, Furtive poisoner, Forest survivor, Forest trapper, Forest alchemist, Expert herbalist, Green cartographer

Expertise: Natural assassin, Assassin of nature(Poison user), Stealthy spy, Chameleon stalker, Forest assassin

Izuku's quirk:

Summons the Shelter, which is a cave system and gulley, the caves fully furnished and the gulley a winter landscape with forests and lakes

The masters: There are 1 master per house and 1 Specialization master per house, 3 teacher rangers per house, 10 cook rangers, 2 mail rangers, 2 healer rangers with weak healing powers

An armory and forge

If someone gets a specialization the quirk gives them a small added ability that goes with it while also complementing the persons quirk, like Uraraka might get a hover ability that acts like a very weak version of Nana's or a weak magnetic field

Izuku himself has extremely enhanced senses as well as denser muscles and tougher skin than an average person, he can get small abilities if he does a specialization

The rangers in Japan would be kind of like underground heroes in how they work but they work directly for the Prime minister and not the HPSC, as well as military work. They work internationally dealing with underground problems Japan has in other countries, like escapees or military matters/spying

The rangers are allowed to kill as they're military

They can't use they're quirks unless they have a hero license

In this I imagine Stain joining before he has a chance to become Stain, and the Aoyama's doing it as well instead of going to AFO, so Aoyama stays quirkless

Mineta would find it and as he would be young it would stop him from being a super perv that everyone hates, although he'd maintain a more kaminari level perv

I would imagine Bakugo not having an interest in being a ranger and sticking with hero but because Izuku has a quirk they're actually friends. Todoroki doesn't join as he's confined to endeavour, and Iida wouldn't because of his hero family

Only Izuku has 2 specialties

1B:

Shiozaki - Healer guard

Komori - Forest Alchemist

Kuroiro - Stealthy Spy

Extras:

Shinso - Natural Assassin

Stain - Natural Assassin

Toga - Chameleon Stalker

Mustard - Furtive poisoner

1A:

Mineta - Forest Trapper

Izuku - Tireless Tracker/Elemental Fletcher

Momo - Expert Herbalist

Jirou - Assassin of Nature

Kaminari - Elemental Archer

Tsuyu - Forest Sniper

Ochako - Archer of the Wind

Ojiro - Man Hunter

Tokoyami - Forest Assassin

Koda - Beast Master

Shoji - Infallible marksmen

Hagakure - Chameleon Stalker

Aoyama - Forest Sniper

The students not mentioned will not be rangers and will just want to be heros so they still go to 1A

Izuku is born with his quirk

Quirk: Solar system

Details: His hair is made of green fire, his body is constantly glowing and at a very high temperature. Only his mother can actually touch him without burning. His lifespan is connected to the sun making him semi immortal. He has a celestial form that gives him a weapon and increases his size. He can control his fire and has natural radiation, as well as gravity. The radiation doesn't really do anything. For some reason the heat from his body doesn't effect items.

He's capable of giving people the roles of different planets and dwarf planets. When this is done it's permanent and causes some physical changes to the person to make them look more like the planet. For example someone assigned saturn would gain it's rings. They gain a gravitational field around them and the length of their lives is connected to the planet. They also gain the "abilities" of the planet they now represent, these would include the creation and immunity of the gases from the gas and ice giants, being able to survive in those environments, cold and heat resistance depending on the planet, the ability to create snow or ice(Ice giants and mars), Maybe speed for mercury, the ability to summon Neptune's winds and storms, or Uranus's stink.

They would also have celestial forms. The dwarf planets are the same. The moons would be pets that the planet assigned a role to.

I personally imagine Bakugo as Venus.

Chapter Text

In this AU there would be a person who has the quirk/ability to awaken quirks, and they end up bumping into and helping some MHA character changing their lives.

First Mineta - they would likely get Mineta to see a therapist about his hypersexual behaviour if he shows it at that point, or it could go the abuse or bad home route in which Mineta's later behaviour stems from a bad home life and they help him get therapy and a better home. The awakened Quirk that Mineta would get would be the ability to merge and change the shape of his hairballs, change how solid they are, explode them into a sticky purple liquid that gives off a miasma like smell and effect and the ability to grow purple bulbus tumors on and in a person turning them almost into zombies if someone steps on the liquid or a ball touches them. I headcanon that his quirk is a blood based quirk allowing this.

Midoriya - It would bring out an invisible quirk and awaken it. The quirk originally was one that if he touched someone he could pull on a few of their cells and burn them off, but only like a couple, making it so no one realises it's happening. The awakened version would allow him to see and manipulate cells and DNA telekinetically as well as completely destroy cells and dna by burning them if wanted, this makes a powerful mix of both his parents quirks. He could become a healing hero as this could allow him to fix genetic diseases and destroy tumors.

Momo - Erza's Abilities from fairytale

Shinso - The ability to create a fog/mist that shows figures in it. This would allow him to trick people and cause confusion and would work well in tandem with his quirk. Or it could go the voice route where he can throw his voice and affect machines and animals.

Monoma - By taking a bit of dna like a drop of blood or skin he can permanently copy a slightly weaker version of someones quirk.

Chapter Text

I actually believe that in the My Hero universe the 20% quirkless population isn't actually quirkless. This is because after that long and with a majority of people having quirks or marrying those with quirks it wouldn't be impossible but it would be very improbable that people could still not have quirks.

Unless there's a group of people who decided to only marry and reproduce with other quirkless people and continued that, then people who have parents that each have a quirk it would be almost impossible that they don't get one, unless this is at the very start of when quirks first came to be.

So people who are considered quirkless may have an invisible quirk. For example Yoichi or the First OFA user had an invisible quirk, which shows it's possible. Now in the show Midoriya had his foot x-rayed and they said he had the extra joint. The thing is people have been born with normal mutations before quirks and that could be one of them. But they never did blood tests to see if he had the gene for one. This is something that should be done in case a quirk is invisible.

Then there's the fact that Midoriya has green hair, and throughout the show it's been shown that people have a variety of hair colors. That isn't natural and likely comes from people with small physical mutant quirks reproducing and causing this. This may be connected to the quirk gene and considered a quirk. Now even if that's not it, it would still be unlikely that quirkless people are actually quirkless.

There's also the point that after over 200 years of people with quirks reproducing everyone should have evolved to have the quirk gene, and the quirkless may just not be able to show it without blood testing or someone actively testing their brainwave's or studying the inside of their bodies incase it's a small mental or mutation quirk.

This idea can go one of 2 ways. The first is where the creepypasta get reincarnated as Harry Potter characters or The characters become their own Creepypastas somehow.

I will be including Marble Hornets and Ticci Toby in this, although neither are creepypastas.

None of these characters belong to me

Reincarnation AU:

Harry Potter - Jeff the Killer

Neville Longbottom - Ticci Toby

Percy Weasley - Masky

Oliver Wood - Hoodie

Susan Bones - Judge Angel

Hannah Abbot - Nurse Anne

Dean Thomas - Bloody Painter

Luna Lovegood - Sally

Ginny Weasley - Lazari

Ron Weasley - Ben Drowned

Colin Creevey - Smile Dog (Due to him taking Pictures)

Hermione Granger - Kate the Chaser

Cedric Diggory - Dr. Smiley

Draco Malfoy - Jason the Toymaker

Daphne Greengrass - Jane the Killer

Gregory Goyle - Seed eater

Vincent Crabbe - The Rake

Blaise Zabini - EJ

Sirius Black - LJ

Proxy AU:

They would each somehow meet or interact with either slenderman or another powerful creepypasta, which in turn starts them on their path to become a creepypasta.

Chapter Text

The actual SCP foundation was founded in the early 19th century making it possible for the timelines to coincide.

In this universe I feel like Giyuu would end up a part of the foundation after the demons were killed and becoming a 0-5 member and possibly using one of the SCPs to gain a longer life like other 0-5s do.

Or it could be that the Demon slayer corps was a branch of the Foundation or worked with them that specifically fought "demons" and also researched them. This might be a better idea as it means when the corps is disbanded those that survived could be offered a job at the foundation. This would allow them to pass on the breathing techniques and research them while also compiling the data that was collected of the "demons".

Yushiro could work with them as a scientist and use his blood in experiments. While the slayers could become MTF or depending on other skills scientists.

I've been putting "demon" in quotation marks for this because in the SCP universe there are already demons ones that actually come from hell so the creatures that Muzan created would be like Japanese vampires or False demons.

Chapter Text

1st Idea:

Magnus Archives x MHA

Midoriya gets a quirk that lets him become one of the Dread powers. Not become an avatar but actually become it. I imagine he would get a screen pop up that lets him choose which one. It would show a description and the powers of all of them so that he can choose. Once he chooses he gains some of the memories of the original entity. Not all of them though, only enough to change his views. He'd be able to make people Avatars of his chosen fear as well. Later on he finds out he can assign people their own dread power, for example making Bakugo the Hunt or Flesh. When this happens like with Midoriya they become that entity and gain some of its memories and all of its abilities. These people will also be able to make people avatars of their fear as well. Midoriya can't give people the same fear. People who are now an entity when they choose their avatars they can choose which abilities they gain.

Midoriya would be the most powerful of the new Powers as in this world he was the first.

2nd Idea

Quirk: Host

Midoriya's body can Host people or creatures. For people this is limited to people with body snatching quirks like the slime villain. For creatures it's limited to insects, Arachnids, and smaller snakes. When a person or creature enters his body they're transported to a pocket dimension within his body. His body holds a different pocket dimension in each of his organs, limbs, brain and heart. The terrain changes with each one. This is because it would be weird to have bugs just crawling around under his skin. If he's cut depending on where he was cut and how deep whatever he is hosting in that area can come out. He can also create holes that allow them out. Once a creature or hive moves into his body they develop a sort of telepathic link that's able to get ideas across. The longer a certain creature lives in him the stronger the bond. He may also get small abilities from them. For example if he hosts bees somewhere he could make his sweat secrete some honey or gain bee vision. But he can't grow wings or a stinger. The abilities need to be small.

Another effect of his quirk is that he can't get sick. Because bacteria and parasites are creatures they can live in him with no effect to him. But he can still get people sick. You could make it so that he can control the bacteria and any parasites in him if you wanted. Viruses I don't know about because I don't know if they're alive or not.

3rd idea

Quirk: Soul

This one is simple he can remove someone's soul from their body. He can see how good or bad a person is when looking at their soul. The darker it is the more sins they committed, the brighter the more good they've done. When he removes a soul he can do a few things with it. He can put it into a body that no longer has a soul or doesn't have a soul yet (Like fetuses), He can send them to hell or to heaven. The hell or heaven here though is also part of the quirk and aren't the real thing as no one knows what actually happens after death. They're both pocket dimensions. Hell is a prison like place where Midoriya can put sin ridden souls so that they can suffer and purge the sin from themselves, depending on how bad the sins they committed were equals the level of security and added punishment. The other heaven is basically what the person may have wanted most in life or if they want something else it can be a beautiful world where one can live and find peace before they decide to truly move on.

The thing is when he takes a soul the body doesn't die. The soul is the persons being, all of their good and bad, their thoughts and emotions, who they are, but this doesn't affect the biological processes of the body. Because of this the body lives on until it dies naturally or is killed.

I imagine him using his quirk to help abuse victims by taking their soul and placing it in "heaven" and then taking the body and getting it fixed and healthy before returning the soul.

He can also put souls in a robotic body if it's made right.

If he puts a soul in a new body he has the choice to wipe the soul clean which removes all memories and who the person was, basically acting as reincarnation. Although he can't remove someone's sins so they either have to be sent to "hell" for the sins to be erased or just put in the body. The sins cause the person even without their memories to be more prone to violence and bad luck.

Chapter Text

I got this idea by reading 2 really good fics. The first is Summer Never Fades by Gozzer on Ao3, I liked this one because it gave Scott magic, It is a Dr. Strange/Antman fic though, the other is Combining Quantum Entanglement with Wormholes by Souless_Robot on Ao3 which had the idea that when he was missing for five years in the quantum realm it was actually much longer for him due to time weirdness.

So combining these 2 ideas Scott spends hundreds of years in the quantum realm and because of that over time went crazy. Now because he had hundreds of years and didn't age he somehow gained abilities because of Quantum realm stuff. Now that he's out he's like a weird eldritch being that looks human. He can phase through walls, levitate things, open doors that didn't exist before he opened them, phase into overlapping realities, communicate with insects without the suit, shrink and grow without the suit, sense vibrations, create illusions, talk to beings existing in an overlapping dimension, etcetc. And he wouldn't realise these things would strange and just do them. I like to imagine he would constantly be looking into space, talking to himself, and like lizard blinking.

And everyone would be so confused. But they would ignore it because they want to do time travel shenanigans to bring back the dusted. Then Endgame happens. Then quantomania happens and a bunch of other movies happen, I'm ignoring Spiderman no way home.

Then when it's all done the remaining and new people start living together and people just get used to it. Then Time travel weirdness happens and they all get sent to an alternate past timeline for a bit meeting the past versions of themselves and those who passed, and the past people are just so confused at this and Scotts weirdness.

Any ship is welcome for this unless it's Peter because I don't like it when he's paired with adults. And I think it would be funny if Bucky and Sam were married this could be in a romantic ship way or a queerplatonic way or just in a less taxes way.=

Chapter Text

SCP x Marvel

I have 3 ideas for this one

Idea 1: It takes place in the Avengers universe but other than Asgard and Captain Marvel they have no access or knowledge of other aliens nor the ability to get to space. And Asgard also wouldn't really interact with the rest of space other than the worlds that correlate with Norse mythology. And Captain Marvel mainly stays in space and doesn't keep contact with Earth and keeps the aliens away from Earth. There also wouldn't be Mutants. Mutates and sorcerers like Spiderman being the former and Dr. Strange being the latter would still exist.

So in this while Shield does exist it's and American only Organization and was only founded after Rogers was put into the ice. The idea is that the SCP foundation has been around since the late 1700's and works across the globe like it does in most canons. The other SCP universe organizations would also exist and so would all/most of the SCPs. The ones like "When Day Breaks" are specific to their own canons. These organizations are much more well hidden and protected then Shield because even the government doesn't know about them and they have Amnestics and access to Thaumiel SCPs as well as much higher grade tech.

I imagine that after the Chitauri invasion they would get involved. In this the Chitauri would be a type of space dwelling SCP as would certain other space based races but most of them won't exist. I don't know exactly what they would do but they might capture Thor, Rogers and Banner. There's a possibility though that here Banner ended up with the Foundation or serpents hand after the Hulk was created.

Idea 2: Ant-man or Scott Lang somehow ends up in the SCP Universe and becomes and SCP researcher. In the SCP world the suit and Lang himself would sort of warp making it so the suit actively produces Pym particles and so does Lang but at a much smaller scale. Because it's another dimension and not universe (Universes are part of dimensions, the MCU multiverse is in the Marvel Dimension) the Pym particles don't exist there and the Quantum realm may not exist. Because of these factors and the Pym Particles that surrounded Lang in the suit he gained the same ability as the suit. But it was found that in this Dimension the more he uses the suit the more the Pym particles around him grow in power. This causes him to gain the ability to phase in and out of existence. It also causes him to sort of see dimensions layered on top of the one he's in (These dimensions are different then regular dimensions and tend to be layered on top of the regula dimensions. Think Fran bow and Little Misfortune.

But sooner or later was able to go back to his dimension. But he stayed in contact with the SCP dimension.

Idea 3: Dr. Bright (I do not advocate nor like his creator this is specifically just the character), Dr. Clef and Dr. Kondraki were isekai'd there as Ant-man, Tony stark, and T'challa respectively the last one can be changed as I couldn't think of anyone else. Bright would still have his necklace and it would have the same abilities but he doesn't use them as he grew to really like his new body. Kondraki would still have his butterflies. And Clef would still have his animal camera face ability (although here he can control it) and his third eye (Gotten from fanart).

KNY x SCP

Giyuu is Kondraki and has the butterflies while Douma is Bright.

Harry potter x SCP

Idea 1: Certain SCPs like Scp 049, 035, 073, 076-2, 105, and Mr. Fish get sent to the HP world by way of the SCP 507 and go to Hogwarts. Other than 035 though the others would likely end up as staff as 035 can just hijack someone.

049 would likely teach a medicine class, 073 ancient history, 076-2 PE or be sent to the goblins, 105 would likely teach a journalism class while also helping Filch, and Mr. Fish I really don't know.

Idea 2: I got this one from a fic I read called The Department of F**ked up Sh** by RockyCookie14 in which the department of mysteries is basically the foundation and the SCPs are all creatures, items, and beings that have abilities but aren't magical and can't be affected by magic.

Chapter Text

In this Naruto finds a secret cave full of scrolls with each of the breathing techniques, total concentration breathing, and total concentration breathing constant on them teaching them that somehow came from the KNY world. As well as other scrolls with specialized jutsu to go with each breathing style. These Jutsu aren't known to the greater world and are specialized to only go with a specific breathing style. Other jutsu that are known to the greater world can be used to supplement it though

Team 7:

Sakura - Love breathing - Corresponding Jutsu

Sasuke - Thunder breathing - Corresponding Jutsu

Naruto - Fire breathing or Sound breathing- Corresponding Jutsu

Team 8

Kiba - Beast breathing - Corresponding Jutsu

Hinata - Water breathing - Corresponding Jutsu

Shino - Insect breathing - Corresponding Jutsu

Team 10

Ino - Flower breathing - Corresponding Jutsu

Shikamaru - Mist breathing - Corresponding Jutsu

Choji - Stone breathing - Corresponding Jutsu

Others

Rock Lee - Wind breathing + Martial arts

Konohamaru, Moegi, and Udon - Total concentration breathing and learning the basics

Naruto after finding it would definitely show it off and they would all start training. This would start when they are 5 and continue. In this they graduate at either 13 or 14.

Chapter Text

Water breathing is one of the most common technique used in Demon slayer. So maybe there could be Water breathing Variants. Each Variant has 10 forms other than Giyuu's but the technique changes a bit to better suit the person and so do the forms names. The person may also have a slightly different type of sword or weapon to go with this.

The only one who uses the original water breathing is Tanjiro because of Sun breathing.

Giyuu would have Water breathing Tidal variant

Murata - Deep Sea variant

Makomo - Coastal variant

Sabito - Storm based variant

Urokodaki - River variant

And so on so forth making it more interesting and giving more slayers the ability to use the breathing at its full potential adding more power to the corps. Those that can't use a breathing technique to the full potential here is do to either not having the right training or not having the right body.

I imagine Murata asking Giyuu for training help and then reaching the full potential as they were part of the same final selection and he helped care for Giyuu after. I like the idea of a friendship between the two.

Chapter Text

Mha Idea:

Izuku has a quirk that creates a place like the hotel in the Ghibli movie Spirited Away. It has the baths and special baths like in the movie. A herbalist area filled with different kinds of herbs. A spa section and so on so forth. Izuku can create specialized medicines and teas out of herbs and other ingredients. Some of these herbs and ingredients are actually mythical or from other worlds that he can grow in his garden. the "workers: would be like shadow people who Izuku directs and controls. The Hotel also has rooms and such as well of course.

The thing his his special hotel is only visible to certain people. The quirkless, those with yokai or sentient quirks, people with full body Anthropomorphic animal quirks and such, Like officer Sansa who had and anthropomorphic cat quirk, and people with mind or blood quirks. Intelligence quirks don't count. Nezu is and exception as he's an animal. So people like Tokoyami could see it but Yanagi from 1-b couldn't as her quirk is just a form of levitation. Shinso and Aizawa could as well, but Miss. Joke, and Present Mic couldn't.

Naruto Idea:

Same thing as the MHA idea but not as a quirk rather something that Naruto stumbled upon, that was already running and they took him in and he learned everything needed. He then opens up a location in Konoha. But only sages, those with Dojutsu, the Naras, and Yokai can see and enter it.

Hey everyone! The demo of the new game SUBLIMINAL has just come out. It's a Hyper-Realistic Psychological Horror game. It has many paths and easter eggs and can be compared to the Stanley Parable in that way. The actual game should come out in a few months when playtesting and updates finish for the first chapter. Check it out on Steam if you like horror!
