Chapter 1: First Impressions
Izuku Midoriya was crazy nervous. He still had a hard-time believing he managed to actually pass UA University's entrance exam. And now, he was standing in front of the United Height Dormitory, where he would spend the next three years of his life. To the young man, this all felt like a dream.
"Still nervous?" A kind feminine voice said next to him. Izuku turned and saw Momo Yaoyorozu, his girlfriend of three years, looking at him with a reassuring smile.
"Yup. I mean...I still can't believe I'm here." But as soon as he felt a soft yet firm hand grip his own, his nerves started to fade.
"Sweetie, you've earned a spot here." Momo said with conviction in her voice. "You're going to do amazing things here. And I'm going to be by your side for every step."
Dammit, she always knew what to say to make his insecurity vanish. A few years ago, Izuku was a scared bundle of social awkwardness, anxiety, and depression. But thanks to his black-haired angel (Momo always blushed like crazy whenever he called her that), he was able to break out of his shell and work towards his dream of becoming a hero.
"Right. Okay, let's go!"
The young couple let go of each other's hands and grabbed their suitcases and boxes, ready to move into their new dorm.
Later…
"And that should do it." A muscular man with spiky red hair said as he hung up a punching bag. Eijiro Kirishima was super hyped to be moving into the UA dorms! Now he was officially a hero-in-training, and he was going to give his absolute best. Suddenly, his phone rang with a text, and he smiled when he saw it was from his girlfriend, Mina.
AlienQueen: Ugggghhh! Moving in is such a pain! I'm bored and sweaty!
With a chuckle, Eijiro texted back.
Red Riot: Hey, at least you get to decorate your room however you want. Besides, you always look insanely hot when you're sweaty.
AlienQueen: 'GASP!' Eiji, when did you become such a flirt?
Red Riot: I blame you. You've been a really bad influence on me.
AlienQueen: Ya, guilty as charged. So, are you going to that meet & greet in the main hall?
Red Riot: Of course! It's only manly to get to know your neighbors and dorm mates!
AlienQueen: Can't say I disagree. But I'm just wondering…
Red Riot: Wondering what?
AlienQueen: Whose bed should we break in tonight? Yours or mine?
Red Riot: Who says we can't break in both?
AlienQueen: Oh, you naughty hunk! Anyway, gotta get back to unpacking! Love ya a ton!
Red Riot: Love ya more!
As their text messages ended, Eijiro heard a bump and some light swearing coming from the room next to his. The redhead exited his room and knocked on his neighbor's door. "Everything okay in there?"
"Ya!" The door opened, revealing a young green-haired man with green eyes, a messy bunch of green hair on his head, and light freckles on his cheeks. He was also wearing a plain white t-shirt with the word 'Tuxedo' written on it and blue sweatpants. But despite the guy's dorky-looking face and shirt, Eijiro saw that he had an athletic and muscular physique, though he was nowhere near as muscular as he was. "One of my figures fell off the shelf, but I managed to catch it."
Eijiro had a look inside the greenette's room and saw that it was covered in hero memorabilia and merchandise. Posters, magazines, action figures, and other random merch. From big name heroes like All Might (infact, 80% of the stuff was All Might-related) to lesser known ones like the Crawler.
"Cool room." Eijiro said.
"You don't think it's dorky?"
"I mean it is, but in an endearing way." The redhead said. "By the way, the name's Eijiro Kirishima, and it looks like we're gonna be neighbors."
"I'm Izuku Midoriya." The greenette said with a smile as the two shook hands. "Let's get along."
Meanwhile, on the girl's floor, Mina Ashido had just finished putting on the fluffy pink comforter on her bed, but then she heard someone knocking at her door. The pink woman approached her door and saw a tall, elegant woman standing in the doorway.
"Hello. I'm Momo Yaoyorozu, and I'm your next door neighbor."
Now Mina prided herself on being just as athletic and just as buff as her hunky boyfriend. And while this Momo gal wasn't as buff as her, she was taller than her (hell, even taller than Eiji) by at least two feet. She had some good and firm muscles, but also had plenty of womanly curves, especially in the chest department. Her long, black hair tied in a ponytail, her red blouse top, and her long black skirt gave her this elegant look to her.
"Hiya! I'm Mina Ashido! Nice to meet ya!" The pink-skinned girl said with an energetic smile. When suddenly…
"Poke." Mina jumped back as she felt someone poking her in the abs. Two looked down and saw another young woman with dirty-blonde hair tied in two messy buns, golden eyes, and fang-like smile. She was also crocheting on her knees, which made the two think of a cat oddly enough, even as she stood up. "Hiya, I'm Himiko Toga! Guess I'm your neighbor!"
The next day…
Denki Kaminari was feeling a bit overwhelmed. Yesterday had been all about meeting and greeting his fellow classmates. There were some dudes that made him feel a bit out of shape, like Iida and Kirishima, but there were also plenty of total babes like Asui and Uraraka. Granted, two of the biggest babes, Ashido and Yaoyorozu, were already taken, but he still felt like he had a shot at having some hot, college romance. Especially since he knew there was another class in the hero course.
Later on, everyone had gathered in the main hall of the Class A Dorms, spending some time introducing themselves and what their quirks were. There were some pretty cool people like that Todoroki guy and the frog gal Asui (who insisted that everyone should call her Tsu) and some weirdos like the blood-shapeshifting girl Toga (who spent most of the evening snuggling up against Bakugou) and the short grapeball guy named Mineta.
But when it came time for this green-haired dude to introduce himself, the greenette dropped one hell of a bombshell.
"My name is Izuku Midoriya and...I'm quirkless."
To say the class was taken by surprise was an understatement. A few of the people who saw him at the entrance exam like Uraraka had thought that, based on how much Midoriya had leaped around, evaded, and jumped during the Entrance Exam, Ochako thought that he must've had some kind of super-agility quirk. But as Denki (and the rest of the class) was learning today, while Midoriya was a giant nerd, he was also crazy athletic.
You see, instead of going to orientation like the other classes, their homeroom teacher (a tired, hobo-looking motherfucker named Aizawa) decided to make them take a Quirk Application Test, making all of them change into the blue & white UA gym uniforms. And whoever got the lowest score would get kicked out of UA.
So yes, Denki was feeling a bit nervous, especially since his particular brand of electricity manipulation wasn't suited to handle situations like throwing a non-metal baseball (he still couldn't believe that Uraraka girl got a freakin' infinity score), leaping, and running. Not only were people like Iida, Bakugou, Kirishima and Mina (though that was no surprise considering how buff those two lovebirds were) beating his scores in these events, but Midoriya was also running circles around a few of them. Hell, even Mineta managed to use his grape balls to surprising effect.
And now, they were performing a strength test using hand grips to measure how much force they could put out. Denki knew he didn't really stand a chance against the others (especially against Shoji and Toga, who had transformed into Shoji), but he definitely knew he was doing better than Hagakure and Mineta in this particular test. Looking around, he saw Yaoyorozu looking at the strength grip.
Considering she created a cannon for the baseball throwing test, and a scooter for the running test, the electric guy was wondering what she would do for this test.
"Sensei, how durable is this gym uniform?" Yaoyorozu asked their homeroom, confusing Denki.
"It can withstand the pull and force a gigantification quirk." Aizawa answered.
As if to confuse the blond even more, Yaoyorozu reached into her pockets and pulled out two chocolate bars, one twice as big as the other. After seeming contemplating for a second, the black-haired girl pocketed the smaller bar and unwrapped the bigger one. But before that, the black-haired woman motioned for Midoriya to come close to her. Denki couldn't make out what they said, but he did see the green-haired man pull out a stopwatch. Yaoyorozu then ate the bar insanely fast. And after finishing off the chocolate bar, Yaoyorozu took a deep breath and brought her hands together in front of her.
What happened next got the attention and stunned every student in Class A, all except for Midoriya. Yaoyorozu opened her eyes, the black irises brimming with determination. The black-haired woman's body gleamed with the same light that appeared when she created the cannon and scouter before. But to everyone's shock, Yaoyorozu's muscles began to grow!
It started with her leg muscles, which ballooned up like some was injecting air into the black-haired girl with a bicycle pump. They continued to grow and grow, filling up with more muscle as well as stretching to make her even taller. And to Denki's surprise they only stopped when Yaoyorozu's thighs became as big as his torso.
Speaking of torsos, that and Yaoyorozu's arms were the next bulk up. While most of the black-haired woman's muscles were obscured by the gym uniform, it failed to hide just how freakin' big she was getting. And based on how Yaoyorozu was gritting her teeth, the feeling of forcing her muscles to grow must've been intense, sweat rolling down her forehead with a burst. The black-haired woman's back stretched the gym uniform to its limit, her shoulders becoming the size of medicine balls, and her forearms bursting with power.
When the transformation finished, Yaoyorozu had gone from being fit and athletic to having even bigger muscles than All Might! And aside from her now massive musculature, the black-haired woman had also gained about three feet in height, and (much to certain purple-haired woman's dismay) her bosom had also doubled in size. All in all, Yaoyorozu was now an amazon in every sense of the word, and Class A's reaction was summed up by Uraraka.
"Oh mah god!" The brunette said as Midoriya clicked on the stopwatch.
"Two minutes and forty-eight seconds." The greenette said, making Yaoyorozu sigh. Midoriya saw this and looked up at the massively muscular woman with a reassuring smile. "Hey, you were ten seconds faster than last time."
"I know, but that's still too long." The black-haired amazon said before picking up her grip machine. "Alright, here I go."
A large vein appeared on Yaoyorozu's forearm as she pulled on the grip...and it immediately broke.
"Oh dear." The black-haired girl said while Aizawa sighed. "Sensei, I can make a new on-"
"No need for that. Let's just get to the other tests." The tired man said while the rest of Class A continued to look at Yaoyorozu in stunned silence while Midoriya just smiled at her.
When the tests ended, Yaoyorozu ended up taking first place, with Iida taking second, Kirishima taking third, and Izuku taking fourth. Denki was in the bottom five, with only Koda and Hagakure doing worse than him. Granted, it turned out that Aizawa was kidding about expelling anyone, but that didn't make the situation any less stressful.
Denki was determined to do better next time, electricity crackling around him to match his determination.
Later…
"Aren't you going to change out of your gym clothes, Yaoyorozu?" Ochako Uraraka asked as she and the rest of the girls changed into their regular clothes while the black-haired girl just sighed.
"It's going to be a few hours before I can wear my regular clothing again."
"Speaking of which, just what the heck is up with your quirk?!" Hagakure asked as she flailed her invisible arms.
"Yesterday, you said you could convert the calories in your body to create a whole bunch of shit. How does that translate into you going all She-Hulk?" Jirou asked.
"That's kind of oversimplifying it." Yaoyorozu replied. "Well, the same way I can use my quirk to create objects to pop out of my body, I can focus my quirk inward to create new muscles and enhance the ones already in my body. And like with any inanimate object I create, they'll eventually fade away...or turn back to normal in this case."
"And what about the candy bar?" Toga asked.
"Oh, these are specially-designed calorie bars." Momo said, taking the uneaten one out of her pocket. "I eat these in order to add...well, a rather large amount of calories into my body."
"How many are we talking about?" Asui asked.
"Let's just say that if you didn't work out like crazy, or have a quirk like mine, you'd gain over 100 pounds in four days." Momo answered, causing the girls to freakout at the very thought of that happening to any of them. "After eating one of these, I can create something large, a vast quantity of smaller objects or...well, this." The black-haired woman said before motioning to her hulked out body.
"So you're stuck like that for a bit?" Ashido asked.
"It all depends on how much I exert myself. If I wanted to burn off all the muscle at once…" Yaoyorozu said as she thought about something. "...I could try to lift one of the Zero-Pointer robots."
'JUST HOW STRONG ARE YOU?!' The rest of the girls thought.
Soon enough, the girls left the locker room, heading back to the UA Dorms and meeting up with the guys. Uraraka saw Yaoyorozu meeting back up with Midoriya. And the brunette thought she was going to get diabetes when she saw the greenette said on his tiptoes to kiss his girlfriend on the lips. Yaoyorozu then picked Midoriya up by his waist and lifted him up so he could wrap his arms around her broad shoulders.
Izuku and Momo walked back to the dorms holding hands, the greenette resting his head against the black-haired woman's muscular arm.
Suffice to say, the power couple of Izuku Midoriya and Momo Yaoyorozu made quite the first impression on their classmates.
Author's Note: So what happens when take Mizutori's 'Thank You', Titus621's UA University AUs, and myheadinthecoudsnotcomingdown 'For Want of a Nail' series, throw them into a blender, and mix them in with Pokkuti DNA? You get this one-shot!
Don't worry, I'm not abandoning Red Riot's Muscular Harem, but it's gonna take a bit to make the fivesome chapter extra erotic. But this idea popped in my head yesterday, and I wanted to give you guys something to tide you over until then.
It might not have shown in my other stories, but I am a huge IzuMomo shipper. What can I say, these two are adorable together. Plus, you get softboy Izuku and a taller Momo. And the only thing better than a tall Momo is a muscular Momo!
And just like with Red Riot's Muscular Harem, Pokkuti's Pinnacle of Physique comic really changed how I categorize the different sizes for muscular girls. And with this one-shot, I've introduced the fourth category from that comic into my stories: Hulkout!
I was inspired to make Momo the first MHA girl to hulkout in one of my stories based on DrLoon's recent drawing of Momo. And out of all the series, My Hero Academia seems like muscle growth through strength training or quirk usage would happen naturally compared to other series. But I'll fully admit that I'm not a biology expert, so maybe I screwed up how Momo's quirk works, but then again, this is a story where biology gives a guy with a bird head a Jojo stand. So I think some suspension of disbelief is required.
And I'm not only done with IzuMomo or this AU with just this one-shot. I got three full story ideas that I can springboard from this one-shot;
Green & Black: An IzuMomo-centric story where we still Izuku and Momo's relationship from Middle to High School, Momo discovering how to hulkout with her quirk, their time at UA University and all the action from the original manga/anime.
Hidden Potential: Similar to Green & Black, but with more of a focus around the entirety of Class A in this AU, with all the action, story, and ships you expect from an MHA AU.
Sweet Broccoli with a Side of Beef: A Red Riot's Muscular Harem-inspired story where Izuku and Momo end up catching the eye of a few of their beautiful coeds, who bulk up to join the two for some muscular harem action.
The Hero Course Polyarmory: A blend of Sweet Broccoli mixed in with Red Riot's Muscular Harem where Izuku, Momo, Eijiro, Mina and a few lucky girls (and maybe some lucky guys) bulk up for some erotic, muscular fun.
Like with Red Riot, Sweet Broccoli and Polyarmory will have polls not only to determine which girls would be Light, Heavy, and Superheavy, but also which girls would gain the ability to Hulkout. Also, with these stories, I want to try my hand at telling a legit story with action, romance, and drama, but with all the muscular, lemony goodness you guys expect from my stories.
I'd love to hear your responses in the comments on this site, Archive of Our Own, and Deviantart for which of these ideas you'd like to see above the others. I'll also have a poll on my Fanfiction profile, and whichever story idea gets more than ten votes will be made alongside Red Riot's Muscular Harem.
But who knows. Later on, I might just make all the different versions of this AU after finishing up Red Riot and poll winner.
So discuss in the reviews/comments, cast your votes and have a safe day!
