Idea/Prompt Quirk......... being a Quirk.

123 Upvotes

Kyoka blinked heavily, dragging her slippers across the cold floor of her room all the way to the bathroom. The All Might alarm clock from the room next door had gone off with its usual shrill racket, but she could barely manage to unglue her eyelashes.

She turned on the tap, splashed a handful of cold water onto her face, and looked up at the fogged-up mirror.

She wiped the glass with the back of her hand. Routine morning inspection:

Two arms. One head. Purple hair, short, slightly ruffled from the pillow. Two eyes... green.

Wait.

Kyoka blinked. She rubbed her eyes with her knuckles and looked again. Her irises weren't their usual dark, near-charcoal shade, but a bright, electric green, speckled with golden flecks that seemed to throb in rhythm with her pulse.

Mechanically, she looked down at her chest, scanning the baggy oversized shirt she usually slept in.

Wait a second. Are those breasts? Why the hell do I have breasts?! WHERE IS MY—?!

A mental short circuit paralyzed every single fiber of her nervous system. Kyoka gripped her head with both hands, chest heaving in rapid panic.

....... Wait.

She shut her mouth. She looked down at her slender hands, at the audio jack lobes hanging docely along the sides of her neck, and at the unmistakable silhouette of her own body in the mirror.

I'm a girl. I was born a girl. I've had breasts since I was thirteen. Why on earth am I freaking out over having breasts?!

"I-I'm so sorry, Jiro-san!" whispered a timid, rapid-fire, frantic voice, ricocheting not through the air, but directly against the inner walls of her skull. "It was just a reflex! I spent fourteen years getting used to an entirely different anatomy, and when I looked down, I just panicked and... well, my thoughts got tangled with yours before I could separate myself properly! I'm sorry, really, this is so embarrassing!"

Kyoka let out a long, heavy sigh, resting her forehead against the icy glass of the mirror.

"Midoriya," she ground out through gritted teeth, not bothering to lower her voice. "We've been doing this for three weeks. You promised you wouldn't take over the optic nerve before eight in the morning."

"It's just that last night I was calculating the harmonic resonance of your jacks if we amplify the frequency through bone-conducted shockwaves, and I ended up staying awake in your temporal lobe..."

"Shut up and let me brush my teeth."

Kyoka grabbed her toothbrush. In the mirror, her reflection scowled with annoyance, yet the emerald green in her eyes flared with a spark of raw energy that had never been there before.

Izuku Midoriya's medical history was, in strictly bureaucratic terms, a legal and biological nightmare. Throughout his childhood, everyone assumed he was Quirkless. At fourteen, following an incident with a sludge villain, the truth finally surfaced: Izuku Midoriya's Quirk was being a Quirk. A parasitic, symbiotic bio-energetic consciousness capable of latching onto another person's Quirk factor, boosting it to absurd extremes, and reorganizing their internal systems like a living co-processor.

Aizawa had nearly handed in his resignation the day admissions dumped the paperwork on his desk. Midoriya existed as an analytical, chatterbox soul anchored directly to Kyoka Jiro's body.

Down in the dorms' dining hall, Momo Yaoyorozu held her fine porcelain teacup with her customary elegance, watching her best friend slide into the seat across from her.

Momo would always admit, privately and with absolute honesty, that being friends with Kyoka Jiro was... interesting.

"Good morning, Kyoka-san," Momo greeted with a serene smile. "Did you both sleep well?"

"Morning, Momo," Kyoka replied, dropping her tray onto the table with the weight of a thousand years. "I did. The talking parasite didn't."

"Hey, I'm not a parasite, I'm a conscious organic amplifier!" Kyoka's mouth suddenly protested, her tone shifting into something noticeably higher-pitched and more nasal, just before her left hand moved entirely on its own to wag a finger in the air. "And good morning, Yaoyorozu-san! By the way, I was thinking about the molecular composition of the tungsten you used in training yesterday—if you redirect your lipid consumption toward—"

Kyoka slapped her own left cheek with her right hand.

"Control your hands, Freckles. I'm eating breakfast first."

"Sorry," the voice muttered, this time with her mouth shut, buzzing faintly out of the tiny speakers in Kyoka's earphone jacks like a pair of low-fidelity headphones.

Momo took a sip of her tea without missing a beat. At the start of the semester, watching Kyoka slap herself across the face or listening to her argue military tactics with herself in two different registers would have triggered an immediate trip to Recovery Girl. Now, it was just the standard prelude to breakfast.

"Adjustment issues this morning?" Momo asked with genuine curiosity.

Kyoka rubbed the bridge of her nose, a faint blush of mortification still dusting her pale cheeks.

"The idiot panicked in front of the mirror because he forgot I have boobs."

Momo choked on her tea, catching herself instantly and dabbing her lips with a linen napkin.

"IT WAS A PROPRIOCEPTIVE ERROR!" Kyoka's earphone jacks shrieked in unison at seventy decibels, rattling a plate on the neighboring table.

"Keep the volume down, airhead," Kyoka growled, stabbing her fork into her toast. "Next time, I'm severing your link to the speech center and locking you in the cerebellum for the entire combat exercise."

"You can't do that! If you block the brainstem bridge synapses, you lose the three-hundred percent boost to your jacks' speed, and Aizawa-sensei will make us clean Gym Gamma—"

"Try me."

Momo watched the exchange, letting out a soft, discreet giggle behind her teacup. It was chaotic, unpredictable, and completely disregarded any conventional concept of personal privacy. Yet watching Kyoka's jacks crackle with faint emerald electricity—primed to obliterate any target in morning training—Momo couldn't help but think that, despite the early-morning screaming matches in front of the mirror, they made one hell of a team.

Idea/Prompt – Crossover Weird Sentience

63 Upvotes

Izuku had a quirk...it just never activated until One For All....because it needed multiple minds.

The moment Izuku stepped into the Practical Exam, it made itself known to all. It jumped from robot to robot, blowing most of them up with laughing in a shrill combination of multiple voices. Izuku chased after it, desperate to calm...whatever this was down.

Nezu found all this entertaining, of course. He had deduced what was going on already. Izuku had a sentient quirk. Izuku also had One for All. It had gone crazy on power and was excited to be finally alive in a sense. He sent in more robots to satiate the new life and give the other examiners a chance as this was unprecedented. Sentient quirks were quite rare after all and he was determined to have two to study!

"CoMe PlAy WiTh Me!" It screamed out, jumping from robot to human, messing with electronics and quirks alike. With each jump into a human tho, it seemed to get stronger.

"Knock it off!" Roared back as strange things happened to Izuku as well. Green lightning arced off him as One For All activated all over him forcefully before Blackwhip burst out of his chest to protect him from a rogue robot and another sent to him by his own quirk.

Then the Zero Point Robot rose up...only to be taken over by his sentient quirk...though it seemed to be struggling. "MaKE mE...bABy!" In a distinct female voice before laughing alongside the robot's AI program, making it sound glitchy and shrill, causing many to hold their ears and wince.

Izuku had to rush to the aide of many as the controlled robot caused chaos. As he pulled rocks of the gravity girl's legs, he barely realized he had a weird control over his strength but he was very aware of the other strange powers he used. All Might never mentioned these other powers. Did he even know? It didn't matter, his quirk was hurting people. So he did what he always did. Try to help. He jumped high into the air...only to realize he should have fallen by now and was Floating quickly into robot's face. He hit it and bounced off, now just uselessly floating high in the air. His quirk made a electronic snort. This annoyed Izuku further. "BEHAVE!" He roared as he reared a fist back, only for Blackwhip to come out a form a colossal black fist and punch the giant robot's head apart. In mid air, the sentient quirk had nowhere to go and had a look of shock and glee on 'her' face. She looked to be a digital patchwork of pink and black with floofy hair bigger than his. She had bright green and blue eyes that multiplied for a moment before going back to normal. She let out a joyful multi-voiced laugh before tackling him.

On problem was, this sent them both to the ground like a comet. She shielded him and took most of the blow after quickly realizing what she did, but he still got hurt. By then, the exam was over and Recovery Girl was on the scene. The Quirk panicked, hijacked Recovery Girl and her quirk, forcing her to kiss and heal Izuku.

"Dearie, don't ever do that again if you can help it. But what in the world was that?!" Recovery Girl replied, rubbing her head. It felt a little foggy, like TV static, for just the moment that quirk had her.

Izuku slowly got up, looked to Recovery Girl then to his quirk who hovered around him concerned and back again. "I....have no idea....my quirk just activated today." Everyone just looked at him dumbfounded, especially as his quirk suddenly merged with his arm and it forced one of his eyes to go blue and pink.

TLDR: Izuku's main quirk fully merged with One For All, becoming sentient....who is basically Capri from the 2nd season of Cyberpunk Edgerunners. A quirk that combines with other people to understand the world and mimic quirks while giving izuku access to all the quirks of One for All...because all the vestiges merged into one. It acts like a mother, sister, lover, and total weirdo just like Capri and more. Don't know if I got Capri right, but I had fun.

Idea/Prompt Granddad Might

11 Upvotes

An idea that’s been floating around in my head for a while now is one where All Might is not Izukus dad, but instead his grandfather. Now Toshinoris age is unknown, but per the wiki he is at a minimum 15 years older than Inko, with him being 55 or older at the start of the story, and Inko being 40. So what if you leaned a little on the older side, what if he was 18, or maybe 20 years older than Inko. That’s a fairly normal age to have a child, a little green girl with telekinesis. And a fairly good reason for her own child to be quirkless. And with that quirkless grandchild being obsessed with hero’s, it’s a good way for a pro hero grandfather to connect with his beloved grandson.
Basically what I’m saying is that I want a Granddad Might fic, I think I’d be a fun way to change their dynamic.
You could also have some fun with different members of 1-A learning about it. Bakugo learning that he relentlessly bullied his idols grandson. Todoroki realizing he’s a generation off with his secret love child theory.
As I said, I just think it’s be fun.

Idea/Prompt Izuku gets hit with a quirk that makes him start talking like Yoda

• Upvotes

A few days before the final war started, Izuku got hit by a quirk that changed his speech pattern to make him speak like Yoda for a month.

Despite how weird he sounds everyone is still able to understand him without problem, it just now for some reason when the boy talks everyone just feels compelled to listen him and every time he speaks he feels compelled to say something wise.

Which proves to be very useful as when the war starts he’s able to convince both Toga and Tomura to stand down, saving both of them from their fates.

Idea/Prompt "You Know," Izuku Said, "I Thought All For One's Defeat Would Change The World But...Now I'm Not So Sure."

46 Upvotes

Basically, Japan falls into a massive rut after final war. I think I've posted something like this previously but this is inspired by Star Wars Kotor 2 and how the republic has fallen on hard times due to the realistic effects of the war in the first game:

They were stood near ground zero of one of the many fallen buildings through the city. Clean up was marked to take years upon years of effort given the horrendous economic crash the world had suffered due to the globe spanning villain attacks.

The sky was a muted gray and despite it being close to the end of may, there was a dull coldness that required long pants and jackets.

Iida glanced up at Izuku, wiping a bit of sweat from his forehead as he did. "The world is better off without the League in it," he said. "You tried your best, Midoriya-Kun, don't falter because Shimura refused your help."

"But...is that the answer?"

"Is what?"

Izuku placed a hand over his head as he sat next to his friend, "To...kill them? To lock them away and throw the key out? To never try and understand them? I would never forgive Shimura-Kun, but celebrating his and the rests deaths...I think...in a way I sent the people the wrong message."

"...Pardon my bluntness, but...while the celebration of death is unpleasant, it pales in comparison to what would happen if the League and their ilk had won."

"What do you mean?" Izuku gave him a look.

Iida sat rigidly, "Midoriya, society, culture, and all aspects of life will always be flawed. This is not cynicism, this is an unfortunate truth. Fight as we may for the rights of those with villain quirks, for it to happen after what Himiko Toga was a part of? Not in our lifetime. Even then, if you solve one problem, another problem will eventually replace it. That's why heroes in whatever form will always be needed."

"So it's fine for people to celebrate-"

"They're celebrating because they are not dead. Shimura and the League were the enemies of the world. They were going to destroy it. I know...that sone changed their minds, Toga did, but even then, after everything they'd done saving them would only mean life imprisonment. Some would consider that a fate worse than death."

Izuku thought about this, his knee bouncing up and down. "Do...you think anything can be done?"

Iida nodded, "Fighting for the rights of people with perceived villainous quirks? Of course. I am simply calling out that what the League did shall only contribute to a refusal by the people to understand what makes a villain a villain. People are selfish, Midoriya-Kun. They believe they and their pre suppositioned ideas of the world are always right."

"I can definitely see that about you," Izuku smiled tiredly.

"Quiet. Now, if you're wondering where I'm going with all of this, there's nothing wrong with striving for a better world, but one mustn't be caught up in their own ideals because life will drag them back down to reality. What happens from here? I am unsure, but I know this crashing of the world, the call for action against villains, life will only become harder and harder with every passing day before we see any kind of recovery."

Izuku watched Tenya as he said this, his hands together. He nodded slowly, then stood. "I'm gonna go grab a soda, I'll be right back."

"Mhm," Iida nodded, "take your time." He glanced Izuku's way momentarily as the boy walked slow steps in the dusty ground from the scene.

Discussion Pet Peeves that bothers you

48 Upvotes

Here and there there's always that same tropes that manage to stablish that the mildly interesting story is going to that same trail rails.

Powerful Bakugo I mean, I get it that he can be a compelling protagonist, an antagonist or a cartoonishly moustache twirling evil guy TM but my pet peeve is that, independently of how powerful Izuku is, if he has a powerful quirk, be trained in OFA by another character, hell, even having acted as a hero or vigilante; first class and sport festival, Bakugo kicks his ass. It's funny to think that, by the powerscaling logic, how strong this maniac is? Wherever changes to canon happens, this guy still is stronger.

Mina and Setsuna This one is partially my fault because I submit myself to this due to the search of rare ships. You know the drill, Izuku is nice, girl/girls decide that they have feelings and... these two gremlins decides that is time to be thirsty, kicking the plot of harem/smut/ whatever. Talk about flanderization.

Pity love This one is not so amusing to me as the other two. Some fics decides to address mental health issues which is super valid, as the manga tackles on issues like bullying, lack of self preservation and the social issues like segregation. What I don't get is the setting where the character that deals with those issues receive a confession after their issues or dark past gets exposed. Can y'all see the issue, right? Using love or affection as some sort of pity gift for being strong for enduring abuse and persevering. Which is astounding to me because the opposite would make much more sense. The couple gets together and then they address the mental situation.

These are just me being picky, as these peeves are annoying but I admit that I find entertaining how they are almost a flashlight showing which way the story will follow. How about you?

Idea/Prompt “Who’s ready to learn how to get 100% on any exam?”

71 Upvotes

(College 18)

“Hi, I’m Denki Kaminari.” He said while waving to the camera. “And if you’re anything like me, you know that exams are no joke.”

“Like you, I’ve tried all sorts of study methods. But they just don’t work!” Denki held up a frown face before throwing it away.

“So I started these three easy steps, and I’m sharing them with you! Welcome to A.R.E.!” He then got on top a horse. “Let’s go.”

——

Step One: Analzye

Denki walked through a forest. “First of all, to know your situation, you need to know your enemy. And that means analyzing your teacher.”

He pushed back the shrubs to see Aizawa in his own home. “From here on, watch everything. His movements, his adress, you’ll even need to learn lip reading so you can see what saying.” He watched him with binoculars.

“Hey, he’s talking dirty.”

——

Step 2: Record

Denki wrote things down in the notebook. “The next step is very simple. Just record anything that might be of value. The more secret, the better.”

“Oh hey he has a cat, neat.” Denki smiled. “Just one secret will do, but the more the merrier.”

——

Step 3: Execute

Denki grinned and sat at his desk, ready for the exam. “Now, you A.R.E. ready for the exam. Write the dirty information you have on your exam along with a little message saying-“

He suddenly got serious. “Do it. Give me an F. See what happens.” He then smiled again. “And just like that, you have an A for your exam.”

——-

Denki then sat in the Principals office with Aizawa. “Trying to bribe a teacher is a serious offense. I’m afraid I’ll have to expel you.”

“Now, the issue comes with your teacher being a snitch and ratting you out to the principal.”

Nedzu and Aizawa looked at each other. “…Who is he talking to?”

“I don’t know.”

“So that’s why you have to kidnap his thirty cats.”

“What?!”

“Now keep in mind, your teacher will probably start kicking your ass, but I’ve built up a resistance to pain because I shock myself so much!” Denki said while Aizawa beat the crap out of him. “Nothing!”

——

The three arrived at a warehouse. “Now, he’ll probably immediately rush to the warehouse.”

“Denki shut the fcuk up!” He threw open the warehouse doors and saw his cat… along with twenty nine others in an insane trap. “What the-“

“So you’ll have to kidnap twenty nine other cats, and set them all up in a jigsaw esque type trap!”

Nedzu looked at everything in shock. “What the… how did you make this?”

“I just rolled up my sleeves!”

“You could have just studied for the exam!”

“Aizawa, if you save one cat, your other twenty nine cats will die. But if you save twenty nine cats, one of your cats will die. Which one do you pick?”

“What is wrong with you!?”

“Do you want a list?”

“…I mean…”

A timer suddenly started beeping. “Aizawa, if you don’t let me back into the class with permanent A’s, you’ll lose ALL the cats.”

“Please no!”

“Now, at this point, your teacher will start crying and sobbing, which will make you think twice, but then you’ll remember how your teachers laughed at you when you got a question wrong, and didn’t do anything to stop your classmates from bullying you and calling you stupid, and how your parents made you stay for hours on end to study, and realize that teachers don’t actually have souls!”

“Denki we will let you back in but you have to go to therapy!”

“Sure!”

——-

“And now, you’re set to have straight As for the entire time you’re with that teacher. And you just have to rinse and repeat for all your other teachers!”

“Denki, why do you talk to people?” Hound Dog explained, causing Denki to look back at him. “Do you think it makes you feel heard?”

Idea/Prompt Midoriya with a quirk he doesn’t know he has

18 Upvotes

I had the idea that Izuku’s muttering kept him from discovering his quirk because it’s Mime. It’s the source of his ‘notebook pocket’ because he goes quiet for the .4 seconds he retrieves one, but because he can’t stop making noise it never activated long enough to have anyone realize he had it. He finds out after losing his voice to a cold right before the exam. (Or maybe gets throat hit during, if played silly)

His hero costume gets a zipper on the mouth as well as a sound nulifier. Bakugo on finding out, floats that he’d been telling him to shut up since day one.

Idea/Prompt ??? "Well it looks like I have a son."

126 Upvotes

"Can someone with a quirk like mine become a hero?"

Izuku asked All Might after he was technically rescued from the sludge villain. Despite feeling his time limit getting closer, All Might turned around.

"A quirk like yours? What is your quirk young man?"

He asked since he has a vague idea since he saw the sludge villain not even touch Izuku.

"It's called Infinity. It divides the space between me and any attacks, including range and projectiles. Making it impossible for me to get hurt."

He tells All Might who hums at the description. Already knowing how useful that quirk could be in heroics.

"Young man with a quirk like that you can definitely be a hero. However, from what I see you lack physical strength."

All Might said before taking out and handing a piece of paper with an address on it.

"Go there and I'll have a friend help you build up your physical strength. As I'm assuming you are going to try for U.A or another hero school."

With that All Might jumped away to deliver the sludge villain to the police. The next day Izuku walks up to Dagobah Municipal Beach and sees a somewhat tall blonde man who looks similar to a skeleton.

"Hello young man. My name is Toshinori Yagi and All Might had asked me to help you build up strength."

He toldl Izuku, marking it as the day Izuku starts training physically. Almost a year later it was the start to the third event of the sports festival with Nezu and Toshinori in a booth together.

"Have you decided on a successor yet All Might?"

Nezu had asked him as they watch Izuku Midoriya and Hitoshi Shino enter the ring. Taking a sip of his tea, Nezu sees All Might focus on Izuku.

"Ah I see. Well young Midoriya should be a great pick from what I've seen and heard of him morally. That and he should be physically fit enough to handle OFA."

Nezu said and earned a nod from All Might. Overseas a green haired woman wearing a cloak and face mask was watching the sports festival as her boss came in.

"Hey boss, didn't you say you once hooked up with a woman named Midoriya?"

She had as a man with blue skin and hair walked forward and sees the screen. Smiling at what he sees as he imagines pulling his son into his organization's ranks.

"Well it appears that I have a son Beros. Better get me some transportation to Japan then."

He tells her as he turns and walks away.

"Copy that Flecturn."

Beris said as she watches the purple haired kid try to punch Izuku and fail. Showing that he has a similar quirk to the boss.

Idea/Prompt "Your quirk is ice cream truck?"

166 Upvotes

Aizawa stared at Midoriya, who was sitting in his ice cream truck. It was supposed to a simple quirk apprehension test, maybe scare the students with an expulsion, drink coffee afterwards then nap, but now there was an ice cream truck in campus.

"Yup."

"What does it..do?"

"It's a sentient ice cream truck, it has infinite ice cream among other things."

"Midoriya, as a teacher, hero, and adult, I mean no harm when I say this, but how in the Fuck does this help you in being a hero?"

"Yea, I get that a lot. But, this ice cream truck does more then sell ice cream!"

"Like what?"

"Well, the ice cream works as a quirk enhancing drug when I want it to."

"..."

"Yea, I get that stare a lot too when I tell people that. You should've seen mom's face when she ate one and was able to lift a house."

"..."

"Not to mention that ice cream is just good for morale, both civil and heroic. Imagine that after a long battle with a villain, you and the hero that saved you just stop and each ice cream on a curb."

"This is so weird."

"Yea, I get that a lot."

"Is there anything else I should know about?"

"There's a gun with infinite ammo in the glove box."

"Fucking what?"

"Yea, I get that a lot."

"You didn't think to mention that on the quirk form for the entrance exam?!"

"I never had the chance to use it so what's the point?"

"I swear kids these days get dumber and dumber, the point is that there's a whole ass gun in your quirk!"

"Eh, who doesn't have a quirk gun?"

"Oh, I don't know, maybe someone whose quirk has nothing to do with guns?!"

"Geez, seems like you need some ice cream, sensei."

"Hey Deku!"

"Yes, Kachan?"

"Show him what happens when you eat your own ice cream!"

"Wait...what happens when you eat your own ice cream?"

"Remember that vortex that swallowed Musutafu National park about 10 years ago?"

"Yes."

"That what happens, vortexes."

Writing help I'm writing a Demon Slayer/My Hero Academia crossover fanfiction and I need some advice

4 Upvotes

So I've been playing around with ideas for a one shot crossover fanfiction with two beloved anime, My Hero Academia and Demon Slayer. I love both these shows, they hold a special place in my heart for a reason.

However my problem isn't the story itself. I have a very clear story in mind. The problem is with Muzan Kibutsuji, himself.

A little context is that Muzan had all but annihilated the Demon Slayer corps with survivors scattered around but something during that final fight made him go into hiding. Demons had either died out at this point or production of them had stopped to a grinding halt. Its like at the end of the manga, they've faded into myth and legend. This is still the same old Muzan, the guy who is nigh unkillable except for the whole being allergic to sunlight, can manipulate his body and shapeshift, wants to find the blue spider lily all that.

Now cut to a few centuries later, over 85% of humanity has a superpower called a Quirk, technology has advanced to have robots and holographic imagery. Its exactly as it is in the series proper. Muzan for whatever reason (you'll have to find out in the story sorry not sorry) has come out of hiding and has restarted his quest of immortality.

All fine and dandy!

So my question is how would the world of My Hero change Muzan? Not in terms of appearance but his power set and abilities to alter his body and weaponize his blood. What would happen if he ate a normal person with a Quirk, would he just be normal and be unaffected, would the Quirk factor of a person weaken him or poison him forcing him to eat the few Quirkless people remaining on earth? Or, alternatively, would he be able to absorb a Quirk's power like a vampiric All For One granting him those powers and making him even more powerful?

Its these little things that sorta bug me. I'm the kind of fanfiction writer who stays as close to the source material as possible and altering things only when necessary. I don't want to jump the gun and give him a new set of powers, you know him shooting lasters from his eyes or teleporting like Nightcrawler. Which is why I'm asking what you guys would do if Muzan was in the world of My Hero Academia and how would he adapt to this world of superpowers and superheroes.

Thank you for your help!

(Spinoff of this prompt, https://www.reddit.com/r/BokunoheroFanfiction/comments/1xf4ns4/in_the_gallows_or_the_ghettos_in_the_town_or_the/ )

Earth 2361 - Oneshot

”How could they have found me!?” Izuku thought as he speed through the forested countryside with his jetpack and hover boots. Niko was tucked firmly under his left arm while Niko’s mother was latched onto his side, her hands finding purchase in between his armour plated suit. “I had been so careful!”

The sound of approaching explosions, toppling trees, and muffled curses signalled the approach of his most dangerous enemy.

”Here he comes!” He heard Niko yelp in fear as the ground to Izuku’s left exploded in a shower of earth; he turned around just in time to see Bakugou flying towards him, his eyes bulging out of his head and and foam visible through his faceplate.

Acting quickly, Izuku took hold of both Niko and his mother and chucked them out of the way just as Bakugou tackled him out of the air, his jetpack’s thrusters were crushed and torn off of his suit as he fell on his back, and the two tumbled through the forest, knocking over trees and kicking up earth and dirt.

”Hide!” Was all Izuku could belt out before he felt his face get squashed back into the earth by the flailing body of Katsuki.

Izuku quickly adjusted his footing and with a mighty yell swung his “Megaton Glove” at Katsuki’s face, the heavy metal contraption connecting with Katsuki’s decepticon engineered faceplate with a resounding metallic clank. Spinning around from the force used to swing the deactivated invention, Izuku attempted to lunge at Katsuki-but the blonde had recovered from the previous blow, and once again tackled Izuku out of the air, sending the both of them tumbling further into the forest as Niko and his mother ran along side them.

Quickly recovering, the both of them began to exchange blows-Niko and his mother watching from behind a tree with baited breath as the soundscape of the forest was drowned out by the cacophony of clashing fists and clanking metal.

”Weak!” Izuku chastised as he lifted a fallen tree with his Megaton Gloves and swung it at Katsuki, the improvised bludgeon shattering on impact and knocking Katsuki to his knees. A piece of the tree went flying through the air and collided with the tree Niko and his mother were hiding behind, shattering into pieces. Niko and his mom ran through the smoky forest, shielding themselves from the flying dirt and bits of debris as they searched for a new hiding spot.

Katsuki unsheathed his wrist blade built into one of his grenade gauntlet, which were both now surgically attached to his arms, and attempted to stab Izuku in the gut. “Puny!” Izuku yelled as he blocked the oncoming attack-turning Katsuki away from him, before driving a specially designed wrist mounted brass grapple into his back, causing the rabid blonde to hack up blood as Izuku pulled the weapon out, scattering cybertronian armour and bits of the blondes spine all over the grass.

”Waste of a quirk!” Izuku spat as his now activated Megaton glove collided with Katsuki’s face, the force of the blow sending Katsuki tumbling back even on its lowest setting.

His vision blurry and his ears ringing, the healing nanites in Katsuki’s circulatory system had no time to activate as the sound of something sliding out of a suit compartment came from behind him, and an energon blade was forced through his left shoulder.

”Super supremacist crap!” Izuku shouted as he grabbed hold of Katsuki‘s unwounded right arm and judo flipped the blonde over his shoulders, sending him tumbling even further into the forest.

”Oh shit! Deku’s actually hitting really hard!” Katsuki though in fear as the greenie continued to wail on him, “Better call for backup quickly, or else I’m finished!”

”Hey extras, a little help down here!?” Katsuki yelled to the sky-and like magic, two new figures descended and join the fight.

One cruised down from the sky using a helicopter propellor attached to his back. Tubes, wires, cables, and other electrical components ran over and under his skin to his insectoid face covering, whose optics shined a bright, oppressive red. He came crashing to the ground, busting through small trees and cutting through the bigger ones with his stretching fingers, which now had razor sharp blades attached to them. The battle turned to Katsuki’s favour as the modified “Fingers” ran to the two battling opponents.

Roaring jet thrusters from the sky signalled the approach of the modified “wings”, whose bat wings had been upgraded with Galactic Empire issued stabilizers and movable thrusters attached to his spinal cord for extra mobility. More Galactic Empire equipment and modifications ran over and under his body, making him seem almost inhuman in comparison to the other HPSC agents. He came flying out of the clouds, firing off blaster bolts that shed the bark off of nearby trees before crashing through a row of them with his metallic bulk, before grabbing one still standing and snapping it in half with a twist of his wrist.

The air helmet clad menace eyed the trembling cat child and parent, who had been watching the battle form behind a row of trees.

”Come here, boy.” Wings said, his voice dripping with venom as he rushed after the mother and son duo who had begun sprinting away.

Mama Niko held her son in her arms as she weaved through the trees and underbrush, her HPSC pursuer in tow behind them. Wings weaved past a row of trees and attempted to close the distance between them, but his metal boots slipped on a patch of loose soil, causing him to lose his footing and fall to his knees, allowing the mother and son duo to make headway.

However, their fortunes were not all good as Katsuki, having knocked Izuku off of his tail, rounded from behind a clearing and gave chase after the duo. But the sound of running and yelling warned Katsuki of impending attack as Izuku quickly caught up to him and tackled him to the ground. Shaking the dirt from his armoured suit, Izuku had just enough time to catch a reverse round house kick thrown by Katsuki, before dislocating his kneecap and kneeing the blonde in the face-sending him tumbling a row of trees.

Approaching rocket jets warned Izuku to turn around, just in time to catch the onrushing Wings mid air and throw him to the ground before whipping him in the back of the head with his Megaton glove and forcing him into a chokehold. This allowed Izuku the position to kick the approaching Katsuki square in the face and through the tree line as Wings flailed in his grasp, wildly firing off proton torpedoes and blaster bolts in an attempt too escape. Thoroughly through with the winged agents antics, Izuku lifted Wings upside down and brought his metallic boot to his face, shattering his air helmet and sending him tumbling over the cowering Niko and mother, kicking up dirt and grass as he came to rest in a clearing.

—————————————————————————

A few miles away, a trio of fellow Multi-Dimensional travellers towards the columns of rising smoke brought on by the ongoing battle.

One was a robot in a pilots cap and uniform with smooth white plating, sharp metallic wings, and a facial hud with displayed yellow eyes and a mouth frowning in concern.

The second one was a tall imp in a black suit with white patches all over his skin, two long black horns protruding from his head, a whip like tail that ended in a spade, and a flintlock pistol in his right hand.

The third one was an anthropomorphic rabbit with fuzzy purple fur, pink overalls with yellow buttons, and yellow eyes & teeth.

”Hurry up guys!” N yelled as he flew low over the trees, “Izuku needs a hand!”

”You think we don’t know that!?“ Blitzø yelled at the disassembly drone as it flew away towards the battle, “Besides, he‘s eight miles away! We’ll never get to him in time!”

”Not on my watch!” Jax declared, catching up to the imp, “Hop on my back. Being gifted the physical form of an anthropomorphic rabbit has its perks!”

”Like what?” Blitzø asked as he climbed onto Jax’s back.

”Like the ability to leap about 45 feet in the air without hurting yourself.”

”Wait, whaaaaaaAAAAAAAAA!” Blitzø’s question devolved into a scream of terror as Jax hopped through the air towards the battle quickly closing the distance between him and N.

He didn’t care if most people saw him as an asshole for the things he did in the past. He wouldn’t let that define who he was now. And that kid had saved his life when he was first brought back into the real world on Copper 9, now it was time for him to return the favour.

—————————————————————————

The battle wasn’t going well for Izuku-Katsuki, Wings, and Fingers came at him from all sides as he tried to block and dodge their swipes, punches, kicks, and explosions.

”There’s another infinity stone hidden somewhere on this planet!” Katsuki yelled as he set an explosion off at Izuku’s chest, sending the greenie spinning off balance. “The feline freak and her little cunt can lead us to it.”

Izuku retaliated with a half powered punch with his Megaton Glove, which sent Katsuki flying back. But was shortly socked in the face by a flying Wings with a metallic clank. Leaving him open for Fingers to grab him by the shoulder and hoist him off the ground. Izuku elbowed him in his face, but Fingers slid his rotating finger blades in between the groves in his armour plating, cutting into his flesh and shaving off parts of his ribs.

Izuku kicked out of fingers grasp, but was soon met by Wings buzzsaw arm swinging down through the air and slicing through part of his shoulder. Acting fast, Izuku blocked a left handed punch by Wings with both of his hands, which left him defenceless as Wings slid his buzzsaw up across his abdomen, drawing blood and knocking back before he clonked Izuku in the head with the blade.

Struggling to keep his footing, Izuku felt a hand grab the back of his neck and fling him through the air as the recovered Katsuki flung him over his shoulders and slammed him through a row of trees. Bouncing up off the ground, Izuku had no time to block the round house thrown by Katsuki, whose metal boot collided with his face and shattered part of his helmet, causing Izuku to belt out a groan of agony.

”Izuku!” Niko yelled in horror as his mother had to hold him back from running into the fray in an attempt to save his friend.

Izuku‘s world spun and his ears rang as a proton torpedo struck him in the shoulder-blasting off the armour present there, and a hail of blaster bolts rained down upon him from Wings. Izuku‘s vision became blurry as Katsuki backhanded him in the face and spun him around before hitting him with a powerful explosion, sending Izuku hurdling through the air and crashing down into the forest ground, knocking over trees and creating a crater in the grass.

Izuku tenderly rose to his knee and spat out a glob of blood, hopping that Niko and his mother were hidden well enough as Katsuki and his cronies slowly closed in on him.

”We could rebuild the future in our image!” Katsuki yelled as he drew his wrist blade from his grenade gauntlet, “With those infinity stones at our disposal, we could reshape the entirety of reality. Rebuild every world in our image! An infinite HPSC spanning across the entire multiverse! A multiverse of heroics if you will.”

”A multiverse of your idea of heroics.” Izuku sarcastically thought as he rose to his feet on wobbly legs, using his energon blade as a cruch.

”Come on, Deku.” Katsuki said, his voice cracking with murderous spite and tyrannical intentions, “You know you can’t win against all of us. Besides, is the expansion and evolution of heroics not worth a single one of these worlds.”

No. No it was not. Not with Katsuki a part of it.

Izuku straightened his posture and removed his energon blade from the dirt.

”You’ll never stop at one!” He yelled with determination as he drew a second energon blade.

”I’LL TAKE YOU ALL ON!”

It's either one or two chapters long, adult hero Izuku is trapped under a collapsing building after an earthquake and holds the whole thing up to keep it from killing a couple kids that are with him. I remember he got impaled on some rebar I'm pretty sure near his shoulder or back somewhere and I think his arm might've been dislocated or broken. The kid(s) woke up a few minutes later and found his hero comms and talked to the people outside the collapse in order to try and help Izuku get them out of the building.

Idea/Prompt A CHOICE DRIVEN BY PURE SPITE

148 Upvotes

Three years had passed since he lost his stomach, and Toshinori Yagi already knew that the concept of the "Symbol of Peace" had died the very moment he learned that All For One was still breathing.

An anonymous tip, a trail... a familiar pattern... Toshinori had to think...

A pure successor, a beacon of righteousness to shoulder the weight of world harmony... pure idiocy. If AFO refused to stay underground, he didn't need an heir; he needed a summary execution weapon with a thirst for blood. Someone who wouldn't hesitate to rip out his jugular with their teeth before he could even finish his cartoon villain monologue.

Enter Rumi Usagiyama.

"You want me to what?" Mirko asked, chewing on a carrot with a furrowed brow as she looked him up and down in the alley.

"Eat it," Toshinori said, his hollow eyes burning as he held out a strand of his blond hair. "You're going to inherit One For All."

"I'm gonna need more context, old man."

"I'm going to pass my power down to you, One For All—it's the stockpiled power of eight generations and blah, blah, blah. I want you to find the faceless bastard who ripped out my stomach and play his ribcage like a drum."

A wild, razor-sharp, absolutely unhinged grin curled the rabbit hero's lips. She spat out the carrot end and snatched the hair right from his hand.

"Should've said so from the start."

One For All didn't integrate: it collided with a physique already pushed to the brink of pure biological violence. When sparks of crimson and golden energy began arcing around her hypertrophied thighs, the concrete floor beneath her boots instantly pulverized from sheer vibration alone.

She wasn't about to hold back at 5% or 20%. Mirko only knew one hundred percent and an overdose of adrenaline.

The first time the League of Villains tried to pull off a coordinated move, Shigaraki didn't even have time to scratch his neck. What came crashing through the warehouse roof wasn't a hero announcing that "everything is fine because I am here." It was a living nightmare.

A Luna Fall, supercharged by seven generations of accumulated energy, slammed down straight from the stratosphere.

"WHERE IS THE POTATO-FACED GEEZER?!" Mirko roared, ears pinned back and eyes bloodshot, lifting a villain by the throat with one hand while her legs crackled with enough kinetic energy to split a mountain clean in two.

In the shadows of his laboratory, All For One—still recovering through medical tubes and life support—watched the footage with a bead of cold sweat rolling down his bald neck. Toshinori had always been predictable: upright, honorable, willing to reason or give a warning before striking.

This was not Toshinori. This was a natural disaster, a force of destruction that gave no damn about the laws of physics, hero politics, or due process.

All For One hadn't been hit by a truck: he was run over by a freight train loaded with dynamite, driven by a woman who considered premeditated murder a perfectly valid form of morning cardio.

Idea/Prompt "HOLY GUACAMOLE! AN ELF!" Nejire Squealed As She Pointed At Tamaki.

87 Upvotes

Of all the things Tamaki expected from this girl, being called an elf was not one of them. Yuyu-Chan froze in a strange confusion as the seemingly ice queen Hado-San rushed up to her fellow freshman like a giddy little grade schooler.

"An...elf?" Tamaki repeated, looking from side to side at the staring eyes of his classmates. Mirio was giving him the thumbs up.

"I knew Santa was real!" Nejire chirped, grasping him by the shoulders and causing an immense blush to overtake Tamaki's entire facial structure as she shook him. "Can you lead me to his workshop, Ama...wait, can I call you Tamaki-Kun!? You can call me Nejire-Chan!"

"Yes you can!" Tamaki bluntly stated happily with the goofiest smile imaginable spread across his crimson face. Yuyu gave a glance at him, then Nejire, and signed.

"Are you serious?" Yuyu hissed. "Amajiki..." She grabbed him by the sleeve and loosened him from a yapping Nejire who was going , "don't act like that, you just met her!"

"Let him score!" Someone yelled. Yuyu shot the responsible boy a glare and he sank away.

"A-Act like what?" Tamaki stuttered, suddenly remembering he was in the middle of class. "I was...just asking..."

"Oh right!" Nejire interrupted, bouncing on her toes, "I'd love to go to the culture feastival with you, Tamaki-Kun!"

"Uh...i-it's...Yuyu-Chan's coming too...um-"

"I can learn all about how your kind make the toys!"

"My kind...oh right-"

"He's not an elf!" Yuyu interrupted. "His ears are like that because it's a byproduct of his quirk! Elves aren't real!"

Suddenly, Nejire was pouting, but that only made Tamaki blush harder because his classmate seemed to think that cutely puffing her cheeks was how a pout was expressed. "And how do you know that? I've seen an elf before!"

"...Where?" Yuyu looked tiredly at her.

"Right here!" Nejire threw her arms around Tamaki who froze up like he was in a block of ice, "he has pointy ears! A thin body type-"

"Thin?" Tamaki whiningly repeated.

"And he's very good looking! That's what an elf is!"

Tamaki could've died a happy man right there, but life went on, and Yuyu looked exasperated, saying, "You just went from Santa's elves to Lord of The Rings, that's...oh my gosh, Tamaki-Kun! If you say you're in the archery club, I'll destroy you!" She yelled as he looked outside to the nearby range down the hill.

(College, 18)

“What?” Sato asked while baking a cake. While Denki frowned in thought.

“It’s just… I’ve been thinking… so whenever you eat sugar you become stronger, more erratic, less sane, things like that?”

“Yep.”

“Okay, and after wards you feel drained and tired?”

“Yep.”

“…Dude are you just guzzling cocaine?”

Sato widened his eyes and turned around. “What?!”

“Because I just described things of what happens when you do cocaine.” Denki held up the article. “And whoop de doo, you answered yes to all of them.”

“I thought you were asking me about sugar!”

“Well the fact I talked about cocaine and that you answered correctly with the effects of your quirk isn’t exactly confidence bringing!”

“Look, there are lot of similarities!” Sato noticed everyone looking at him. “But my quirk is sugar rush!”

“Oh then you won’t mind letting me have some of your sugar.”

Idea/Prompt – Crossover Both Izuku and shoto are the avatars

12 Upvotes

-Izuku and shoto are the new avatars after Korra.
-They are not brothers, but the spirits of rava and vatu reincarnated separately.
-There are fewer benders in this world. As quirks started appearing, bending became rare.
-Some benders become heroes or villains.
-A bender is guaranteed be born as long as at least one of the parents is a bender. In rare occasions a bender can be born of two quirked parents, usually either by spiritual reasons or an ancestor was a bender.
-A bender cannot have a quirk
-Bending tends to appear a little later than quirks. So it’s common to think that a child might be quirk less, when in reality it’s a bender.
-Bending requires training to really develop, but it can manifest in rougher movements, but it’s less powerful and also less precise.
-Izuku awakens his element (fire) in his fifth birthday. He gets still bullied by katsuki. His father is a bender so he teaches him the basics.
-He awakens fire first because he was was expecting to have a fire based quirk, like his father. But earth comes to him more naturally.
-Shoto awakens his fire at six, endevour thinks he has failed. And shoto managers to play with his siblings for a little longer before starting training. A little after he awakens water as ice. But he doesn’t recives formal bending training so while he has raw power, he lacks a lot on finesse.
-The burn scar still happens and shoto tries to reject his fire.
-Izuku awakens earth at his tweens but his father tells him to hide it. He still practices in secret.
-Time skip to ua. Nedzu is part of the white lotus, and sees Izuku doing earthbending during the exam.
-He creates an special plan of studies for him, and he reveals to him he is the avatar.
-Izuku is shocked it takes a while for him to process it. But quickly takes on the responsibility. But still refuses to use all his powers yet, because of what his father said.
-Nedzu respects his decision but Midoriya dad’s descisions still makes him a little suspicious.
-Shoto ever since metting Midoriya feels a weird connection to him. He tries to understand it and shake it off as he isn’t here to make friends. But he can’t help it.
-At first, he believes it’s romantic, but quickly shuts it down, it feels like a brotherhood connection to him.
-Izuku feels it to. But shoto is really closed off.
-He notices that shoto’s control over ice is in a certain way wrong. And wonders why he doesn’t uses his fire.
-By the time the sports festival arrives Izuku has mastered fire and earth and has started learning air. Water it’s pretty dificult for him.
-Nedzu asks him if he is going to reveal his powers in the festival. Izuku isn’t sure. But he still wants to give it all.
-During the festival, shoto tells him his story.
-Izuku tries to tell him that he shouldn’t let his dad ruin this. That he has to give his all.
-Shoto responds what about him. He has realized that Izuku has another quirk, but he doesn’t use it either. Why would him have to use his fire while Midoriya refuses to use his earthbending.
-Bakugou overhears, he is absolutely pissed off not only at todoroki, but to Izuku. Both have been sub estimating him. He swears he his gonna win.
-In the fight between Izuku and shoto both start using only part of their abilities. But the more the fight goes on, the more Izuku realizes that he has to change, especially in order to help shoto. So in the last moment he earthbends, and tells shoto that he was right: if both of them want to be heroes they have to give it all.
-Midoriya uses both fire and earth and the ocasional air shoto is having trouble and in a moment of desperation he ignited his fire.
-The fight goes on and for a brief moment, enough for Midoriya to notice, he uses a water whip. Both of them are shocked.
-Izuku urges shoto to use fire bend, copying his movements, and when he does his flames are more controlled and powerful.
-Then he urges him to water bend. (Even if izuku hasn’t mastered yet he knows the basic postures) at first shoto is doubtful but that connection to izuku appears again and trust him. At first he just moves the ice and then it turns into water. Shoto is elated. Izuku grinning like crazy.
-Then Izuku earth bends and urges shoto to do the same. This time there is more resistance, but shoto does anyway, and it works! Both teens are laughing like crazy.
-The fight turned into something akin to dance both teens comparing skills, lost in the moment. The connection widens, and they realizes they are both one. The avatar.
-The public becomes silent, then becomes crazy none can begin to understand how this is possible. But the display in the battlefield is both heartwarming and mesmerizing.
-Endevour’s emotions go from satisfaction, to shock, to confusion, and an even bigger mix between them. He believes that he will finally surpass all might through his son.
-Both present mic and eraserhead are shocked they have absolutely no idea of how this happened. As none had on record that Izuku and shoto had the same quirk.
-They recive a desperate message from powerloder, who is watching alongside Nedzu, telling that the principal is laughing uncontrollably and it’s absolutely terrifying.
-Nedzu is losing it, but in a good way. Because turns out there’re two avatars, both of them in his care. For the first time ever in the avatar cycle.
-All might is mortified. He thinks all for one has something to do with this. He desperately wants to save both teens.
-All the benders over the world are overjoyed as the avatar has returned, but not just one, but two.
-There are some groups that are terrified or angry and set their sight on capturing or killing them.
-Izuku’s dad is mortified. He desperately wanted to protect his son and now there is no turning back. Or perhaps he need to resort to more dire methods to protect his son.
