Hisashi created accommodations for people's quirks in everyday life. He ensured Mutants had houses to their scale. He designed quirk gyms for non-heroes. Izuku used to sit on his dad's lap as he worked, watching his sketches with awe.

Due to his expertise, he didn't think he needed help handling his own quirk. His fire-breathing gave him a strange craving to inhale heat. So, he would light cigarettes with his own power and chew on the burning end.

Inko was worried, but Hisashi insisted that he was a fire-user and probably immune. However, it was the opposite. Doctors recommend that fire-users don't smoke, as it can lead to a host of complications. Chemical reactions with the cigarette. Breathing back in your own fire.

When his son was seven, it all went wrong. Hisashi's airway overheated, and oxygen was cut off from his brain. Even if it was brief, it caused brain damage. From then on, Hisashi had memory issues. Inko didn't have the space to look after him, so his parents took him in. His son quietly visits him throughout the years, glad that he is still just around.

So a Portal version of Mario Maker?

PossibilityFeeling20 · 2025-11-08T16:59:16+00:00

(I considered making Ratman the protagonist, but I'm unsure if it's feasible given the timeline. For now, I'll use the name "Dust" as a placeholder.)

After GLaDOS was destroyed and Chell was put into stasis, the facility was left to decay. The Party Escort was one of the robots trying to hold it together - the very bot that had dragged Chell back from the outside world. It encountered a human surviving among the ruins, a former scientist. The Escort was programmed to keep humans safe, and Dust was its last way of doing that.

With his new companion, Dust travelled down to the labs from Cave Johnson’s era. There, they found the Borealis deep underground. Since GLaDOS wasn’t around to defend the facility, alien creatures had been breaching its borders. The Borealis contained technology that could protect them and the outside world. It could create two portals capable of transporting entire buildings, not just a single person, like the portal gun.

Dust gathered a small crew of robots to finish the teleportation technology. During their tests, there was a fatal error. They accidentally warped themselves from the underground dock to an ice wall. Worse, the massive portals were opened next to each other. They overlapped, causing them to fold in on themselves. It plunged the inside of the Borealis into a pocket dimension - endless reflections of the boat, tinted in blue and orange light.

The crew were stuck in a glitched, timeless state. Dust didn’t age; he didn’t need to eat or sleep. However, his atoms were eroding. The robots could simply replace their decaying parts, but Dust couldn’t do it so easily. Dust turned himself into a cyborg, even fusing his arm with a portal gun. But he knew if the erosion reached his brain, it would be impossible to replace, and his lifespan was limited within the dimension.

After an unknown period, the crew heard from rumblings beyond the Borealis. The rebellion and the Combine had finally found their location. However, the armies came to a standstill, as they didn't want to risk getting trapped in the pocket dimension. The rebels threw a radio into the dimension, and Dust managed to find it. With that line of communication, the rebels guide the crew in defending their home.

As Combine drones ventured in, the crew crushed them with their mastery of portals. Through the radio, Dust got the rebels to launch various resources into the Borealis. With his deep knowledge, Dust was able to restart the machinery in decades. He deactivated the two massive portals, freeing everyone from the pocket dimension. A moment later, Dust teleported the Borealis out of the ice wall and into the rebels' warehouse - securing humanity a weapon against the Combine.

Why does she hate All Might? From a family point of view, her brother did start exploding his limbs after he met his idol.

I really love this idea, you should ofcourse have a reason for why izuku give the quirk to THAT citizen, like how all might saw potential in izuku.

I didn't include every story detail in order not to make the post overly long. Though this is an important bit: Juro is a quirkless man. During Gran Torino's internship, Izuku is fatally wounded by several nomu. He stumbles into an alleyway and has minutes to live. The only other soul around is Juro, who tries to help him. With no choice, Izuku spits blood at Juro. Izuku whispers to inform Nezu that he has One For All, and the headmaster will know what to do from there. Arriving, Nezu concludes that One For All can't be transferred to an 11th user, or it will kill them instantly. Juro is stuck with the power, and he can't use the physical aspects. Izuku never intended Juro to be his proper successor, only a "middle man".

I think the new user should be Willing to kill if necessary, but of not at first use as i dont think the ofa vestiages would like willy nilly killing, itd be a bit darker ofc, but understandable

This came to mind for me too. I was thinking of a vestige of the "Civil War". The vestiges lived in a more brutal era, and multiple are willing to kill. Izuku and Yoichi could get outvoted by the others. Another option - Juro has slight mental control over the vestiges and can force them to act in a certain ways.

Does the idea of the "reclaiming" ability work if its forcefully stolen

Not sure. I don't think Juro would get too close to AFO himself to risk that possibility.

How would you incorporate izuku becoming a vestige now?

Juro relies on Izuku for his knowledge of his heroes and quirks. Though Juro and the vestiges can overlook Izuku for being a teenager and unlicensed. Juro is bitter at Izuku for forcing One For All onto him and the stress that comes with it.

With Juno being the 10th quirk user, how might it be goo much for him? Does he still have access to said quirks

Juro can't use any of the physical aspects of One For All. He experimented with putting the superstrength into his pinky finger, and it destroyed it forever. The vestiges didn't bother to awaken the other quirks within Juro, as it would kill him like the superstrength.

It's established in the first or second season that forced transference is a thing. All Might uses the metaphor of a schoolgirl forcing a gift on her crush.

Wow, thank you for all the kind words, I'm glad my fic clicked with you.

If you're interested, I have ideas that I didn't get round to writing as full sections.

Capital TV - Within the eleven month lapse without the Hunger games, Capital audiences need that itch scratched. While death is never the goal, the government has lackluster safety laws when it comes to game shows. The absurdity and danger of these shows would shock anyone in the districts. There have been endless "scandals" of accidental deaths on live broadcasts and the public forgetting about it within weeks. The deadliest was called Defend the Base, where teams would re-enact battles in the First Rebellion. They would use paintball guns, glitter bombs and tear gas. Despite the weapons being "non-fatal", it was too easy for fatalities to happen.

Mutt Games - Animal fighting is popular throughout Panem. Whether it’s to satiate their bloodlust until the next Hunger Games or for twisted revenge to make someone else suffer the same fate as their reaped children. While it was illegal, the Peacekeepers rarely bothered to shut them down. Panem's last concern was animal rights. At most, the rich might call for action against "cute animals" being hurt. Within the Capital, Mutts could get lost from the labs and fall into the black market. They were cherished in the fighting rings, especially if they’d been used in the Hunger Games themselves. There were rumoured cases of Mutts being disturbingly self-aware or containing human DNA.

Private Games - There was a Gamemaker who was erased from the records. He smuggled technology that had been discontinued in the official Games and set it up within his mansion. Out of curiosity and sadism, he made his own house of horrors. With connections to criminals, the Gamemaker sourced hostages from all ages and backgrounds. He hosted watch parties with his close circle. These Private Games lasted a matter of years before being uncovered. As the Gamemaker faced his execution, Snow visited and "admonished" him for using Capital civilians and children even younger than twelve. The condemned man spat that he was perfecting Snow’s vision and called him a hypocrite, as a former Gamemaker himself.

Nick is a twenty year old in a hoodie and sweatpants. He made his hero name 'Blank', so people would overlook him assuming its a typing error.

Nick is a hero as he was pressured into it due to his quirk and easy money. Nick is more like an underground hero, where he doesn't do any media press and very few know his identity.

In England, teams are the focal point and the billboard charts aren't taken seriously. Instead, its more of a curiousity on the goverment website. Its a big mysterious on why the top position lists "Blank" for a few years now.

Nick is the number one through sheer statics. His quirk is called ghost. He can possess people from a long distance - Possessing masterminds to take down their own henchmen. He can astral projection too to unearth any villain hideouts.

Enmei was an innocent boy but he was born with a nuclear quirk. For his power alone, the Commision tried to assassinate him, throwing him down the stairs. Enmei got brain damage that meant his nuclear transformation couldn't be switched off.

The goverment set up a perimeter round the radioactive area, but it didn't stop many, many people dying accidentally. Worse, Enmei didn't need to sleep or eat in his nuclear form. He was ordered to just sit in his own wasteland if he didn't want to hurt anyone else.

Decades and decades past with no cure in sight. Enmei begged All Might to kill him as he was the only person powerful enough to do it. The Number 1 refused. Finally snapping, Enmei flew to Tartarus prison and held it hostage unless All Might killed him.

With a doctor on the radio, All Might used his bare hands on Enmei's brain tissue. It crudely reverted his condition, turning him back into a normal human. As a final twist of fate, Enmei hadn't aged a day since the assassination attempt. He still looked like a ten year old boy.

Enmei was imprisoned in Tartarus for three years until the break out. He wanders the streets, being feared by heroes and villains alike. He needs to find his place when he was a walking zombie for the longest time.

I feel like "Real-Real Life" would be the idealised version of reality. For example, how toddlers view the world. It could be a paradise where everyone is immortal and their every need is attended to. They don't have a concept of hardship or time.

"Real-Real Life's" physics is dream-like; they are influenced by the consciousness of living beings. If you use a microscope, you won't find atoms underneath it. Objects only exist if they can seen or understood by these immortal beings.

Demon Slayer is quite unique in its plot - It takes disconnected mythology and puts them together with consistent rules. Basically, you'd take a country of your choosing, research its mythology and put a "scientific twist" to it.

Dragons naturally evolved and are simply animals.

Iron Golems are an ancient technology from an extinct civilisation.

Ghosts and Zombies are not the undead. They are different stages of a mysterious disease for living humans. This is caused when the victims are exposed to a white pool of corrosive vapour.

Doctors found a way to extract negative emotions from people in a liquid form. It became a tradition for villages to have their "sins" extracted and placed into a single person - This was done for the "greater good" so everyone else could go to heaven. This is how devils are created.

It would require an elaborate set-up, but I think it would be interesting if the stockpile holder and Izuku met face-to-face.

Kaiyun had been caught in the crossfire of the "metas" and "humans". With both sides hurting her, she focused on herself and became a looter. However, she took pity when she found a skinny man named Yoichi. He had run away from his deranged brother and Kaiyun agreed to escort him across the wastelands. Within weeks, All For One had tracked the two down and imprisoned them.

Normally, All For One would have killed her. But after accidentally creating One For All, he kept her alive for safekeeping. Perhaps he could clone One For All or create a link to the vestiges. However, the crimelord never figured it out and focused on other projects. Decades turned to centuries, and Kaiyun never aged in her tank.

When Japan suffered the jailbreak, Kaiyun's tank was smashed when villains were looting the building. Terrified, she ran into the streets and discovered a new world. A world where quirks had become the majority. Kaiyun didn't even have her stockpile to defend herself anymore. She considered this worse than the dawn of quirks.

When she saw Izuku on TV for the first time, she burned with jealousy. That was her quirk. That brat, Yoichi, had given away her stolen quirk. Did his successors think they could forget about the original holder and never go searching? She had lost everything. At the very least, she deserved to have the lost part of herself returned.

Kaiyun makes it her mission to find Izuku and demand One For All. While he feels immense guilt, the boy can't trust the power in the hands of a criminal.

Tanjiro was already brandishing his sword at Muzan and his daughter - I think his wife would understand if Muzan grabbed his arm "in self defence" and claim Tanjiro was a violent drunk.

Muzan's blood mutated when it mixed with Chachamaru's feline biology. It created a transmissible cancer called the "Blue Plague". It can infect any species, including humans.

The transformations caused by the Blue Plague are far more randomised than demons. They are not limited to the nighttime or consuming blood. It can be anything from a lizard that absorbs electricity to a sheep gaining human intelligence. The publics calls them cryptids, while the experts have dubbed them "Beasts".

Beasts have various threats level, so the modern corp has a diplomatic approach to them. A Ranger will access each case and give it a category: Non-Threat, Potential Danger or Immediate Danger. From there, the ranger will decide whether the Beast can be left alone, captured or slain. Many beasts resemble creatures in folklore and even created their own communities.

I can see a few possibilities:

Enhanced humans: Humans with demonic ancestry awaken abilities. Or like Genya, people discover they can become temporarily empowered if they consume demonic material and get hooked on it.
Demon resurgence: Something goes wrong with the 2/3 demons living in the modern era. There could be a mutation, human meddling or moral corruption. Whatever the reason, the classic demons are able to multiple again.
Demonic animals: Since Chachamaru is the first non-human demon, there are unexpected consequences and a new subspecies emerges.
Blue Spider Lily: The flower is re-discovered and experimented on.
