It's been a little while since the Swappening has happened. Okay, just one week really. But hey, even in one week a lot of time can pass. In which case, Midoriya Izuku used that time to train his new body and Quirk, which wasn't entirely much if he was being honest. Turns out, whoever owned this body, already did a decent workout as he felt some strong muscle underneath it. If anything, the extra exercising was really out of habit by this point.

As Izuku ate her breakfast, she then overheard some of the news.

"And we see none other than Mirko, still kicking butt in the body we identified as none other than Kazuho Haneyama, also known as Pop Step, a famed celebrity dating the Crawler. Unlike most people, Mirko has kept her Quirk."

'Things really have changed.' Izuku thought as she ate her food and watched the news. Gazing at all the changes occurring in hero life since the swap. Some minor, some big-

"Hello Izuku sweetie."

-and some HUGE, as instead of his small green haired kind mother, a muscly man with big lips and spiked hair in an apron came in. Izuku having to stop herself from spitting her milk as she saw her new 'father' enter holding his lunchbox.

"H-hey mo-dad." Izuku spits out and does her best to not seem freaky. To be fair, his former mother wasn't happy about getting this body either. Hugs and kisses are especially awkward these days.

"Well then Izuku," His dad told him as he set down the lunchbox and touched her shoulder. Pretend he's a woman again. Pretend he's a woman again. Pretend he's a woman again. "I hope you do well in your exam. Especially now that you have a Quirk and worked so hard on it this past week."

"Don't worry mom." Izuku smiled beautifully. "I will." Then, while reluctant on both sides, the father and daughter hugged each other as Izuku then let go and grabbed the lunchbox. Today was a new day, and she intended to pass the U.A. Exam. Which of course won't be easy seeing as U.A. is the toughest Hero Course in the entire country. A Hero Course that that is designed to give every student the tools and opportunity to become a great Pro Hero. Where the applications accepted were 1 in 300. The toughest and most difficult course in all of Japan, and only rivaled by a few from here to elsewhere.

Grabbing her bags, Izuku left to show this exam what she had.

'And already I feel queasy!' Izuku thought as she looked at the gates that allowed one to enter UA High. Imagining all the greats that entered before him. Endeavour, the man (or woman now), who had the greatest record in stopping crime in history. Best Jeanist, a legend in the popularity polls and charitable works, even in a new body he's still fancy and likable. Not to mention his hero and the Number 1, All Might! It's like in order to be the best hero, one just had to be in UA and pass!

'And even though I don't have his Quirk, All Might still believes in me.' Which means Izuku has to prove her worth in this exam. Not that it would be easy, but she felt certain she could pass the exams written portion, thus leaving only the practical.

Izuku just had to hope she passes, having gotten here just a bit early and is on time overall.

"Piss off." Then felt someone bump into her and push her aside. Flinching, Izuku looked at the person who did it. Some girl with a rather round face, brown eyes, and brown hair. Looking cute but ruined by the murderous look in her eyes. For a moment, that face looked like…

'Kachan…' Blinking, Izuku then saw the girl was gone. Already having been consumed by the crowd of students...and adults. Statistics say that while most people swapped with a person near their age, a few ended up in the older or younger category. There were stories of some who were children again.

Regardless, seeing that girl made Izuku think back on her childhood friend. It's been...awhile since they met. More so with the swap happening. She didn't even know what he (or maybe even she) looked like. But maybe...maybe she'll see Kachan again. Knowing him, a little swap of the body won't stop him. Heck, even if his Quirk were swapped, he'd still go to UA High no matter what. That's how determined Kachan was in being a hero.

"Well…" Izuku says, "Let's get started." So Izuku took her first steps and had to hide a squeal as she entered the great U.A. High. While she wished to just look around, she had to see the speaker in the auditorium. Though Izuku may behave slowed down a bit for a few parts to see.

Specifically, the All Might pictures of him winning the Sports Festival!

Anyway, Izuku soon made her way to the auditorium, excited to see all the people joining the U.A. Exam...only to be confused when she saw how the auditorium was filled with less people than she expected. Like, way less. 'I wonder what's up?'

Sitting down, it was then the spokesman came up to speak. According to the pamphlet from earlier, it would be none other than the Hero Present Mic that would do so because of his loud voice. While Izuku recognized the gear on this persons next, a type of portable sound-speaker system, she didn't recognize the face. Though to be fair, when the swapped first happened, she didn't even recognize her mom and shrieked like a girl both on seeing her mom's new form and her own new body.

"HELLO THERE UA!" Yep, that's definitely Present Mic, as he still has his own Quirk. It's been stated that while the swap then change bodies, there were also changes in Quirks to like his mom, with those like Present Mic here keeping their Quirks. In this case, here, Present Mic had the body of a man with wavy shoulder-length light-gold hair and triangular eyes and appeared to be some rock star punk guy. Wearing the usual clothes the hero was known to wear.

"...No way...Dad…?" Blinking, Izuku turned to see who said that, only to find nobody. Or really, nobody to pin on who said it. Must be his imagination. In any case, he turned back to hear the orientation.

"NOW THEN MY PEEPS," The loud hero yells out to everybody. "AS YOU ALL KNOW, THINGS HAVE BECOME DIFFERENT THESE LAST FEW DAYS. FROM THE HAIR, YOUR CLOTHES, GENDER, EVEN QUIRKS AT TIMES! HECK, IT'S ALSO FOR THAT REASON MANY PEOPLE WHO APPLIED AREN'T HERE!"

That...made sense actually. While the Quirk Izuku thought was said by All Might to kinda be like One For All in terms of strength, what about others who's Quirks ended up changing? The power they trained for their lives to enter this exam, suddenly just swapped over a week ago? It made sense they would drop out. Heck, word is many minor heroes have quit already because they gained strange new powers. After all, they couldn't risk their new powers, or in some cases, new bodies.

If anything, had things been different, Izuku might have been one of those people.

"ANYWHO," Present Mic continued on. "THOSE OF YOU HERE ARE THOSE WHO EITHER KEPT THEIR QUIRK….OR HAVE A POWER YOU BELIEVE WILL STILL HELP YOU OUT. REGARDLESS, WE'LL FIND OUT IF YOU'RE WORTHY OF U-A-HIGH!" Suddenly from behind the screen lit up. Izuku paid close attention as if this were one of Present Mic's radio shows of the week, which she always paid attention to. She couldn't help but stop a squall leaving her lips.

"Shut it!" A feminine voice told her. It sounded like-

"NOW THEN, LET'S GET STARTED!" From the screen images of all sorts showed up. Where the hero many call 'The Loudmouth', explained the situation. How each person in this room will be assigned to different areas from A to G, and where they can bring whatever equipment they needed. Where in these faux-cities, they'll conduct a test that will last for ten minutes. Facing off against three of these faux-villains that gave them all certain points to their score.

"Excuse me, sir!" Then from the stands a young-uh, actually grown-person stood up. A tall, bald, and muscular man with shadowed eyes and no hair on his face or head wearing a clearly custom made school uniform. Yep, felt weird to see what many would think is essentially a grown-man repeating school. Though the swap has made life unnatural to the point its being compared to the Rise of Quirks.

"I must ask a question. And that is, this pamphlet states right here that there are four varieties of the faux-villains. Not the three seen on screen." People began muttering, as they realized he was right. There are supposed to be four villains, not three. "As such, I must ask if this is a mistake, which is unbecoming of one of the best hero schools in U.A. High. We are trying to be model heroes."

"NICE CATCH THERE. ALLOW ME TO EXPLAIN!" In Present Mics words, the explanation was actually simple. Like the old game called Super Mario Bros, this exam had one faux-villain comparable to what was called a Thwomp. "IT'S ALSO WORTH ZERO POINTS!" Present Mic added. "EACH SITE HAS ONE OF THESE BAD BOYS, AND ARE REALLY JUST AN OBSTACLE."

"I see. So like a video game, and just a machine to avoid." The grown man says as he bends down. Izuku able to see what appeared to be some kind of vehicle engines on the back of his legs. "Thank you for the information, and apologies for interrupting."

"IT'S COOL!" Present Mic laughs. "FOR NOW, LET'S JUST CONTINUE ON WITH THE TEST HERE. NEW BODIES OR NOT, NEW QUIRKS OR NOT, YOU ALL CAME HERE TO SURPASS THESE OBSTACLES TO BE FINE HEROES. AS A MOTTO OF A FAMED HERO SAYS, PLUS ULTRA!"

And so the orientation ended. After changing -carefully- into a light green tracksuit, Izuku made it to her designated area. A complete nervous wreck and rather feeling shaky on the legs. She looked down to the ground, though soon blushed as her normally baggy tracksuit was now filled with decent sized b-b-breasts!

'I'm definitely not going to get used to this.' Izuku thought as she closed her eyes. Having lots of difficulty with her new gender from using the bathroom to taking showers. Didn't help that this body is rather attractive, making it more difficult for Izuku. Ah, focus! She has to get ready for the exam. Oh, if only there were someone here she knew, heck, even Bakugo. All she saw were many strangers, a few minor people with hero bodies, and that bald man with engines for calves.

Man he looks scary. He looked like a Yakuza.

Trying to snap herself out of this, Izuku then tried thinking back to All Might and what he told her before.

"All right young Midoriya, you're doing pretty well." All Might told her as he smiled at her, who panted a bit from using her Quirk. Her recently new one in fact. "It seems you have a handle on that Quirk quite well. Probably helps its one of the simple but useful types." All Might laughed. "Heck, if I didn't know any better, that lighting affect reminds me of One For All."

"Yeah, thanks." Izuku sits down on a bench and grabs a nearby water bottle, chugging it down. "Which reminds me...any word on it?"

"No, not yet." All Might sighs. "But please, don't focus on that right now. Instead focus on the big day." The hero reminds her. "The UA Exam, and while I can't tell you much, it won't be easy on the practical portion."

"Because I'm still getting used to this Quirk?" Izuku guessed with All Might nodding.

"That Quirk is powerful. Maybe not as much as One For All at full power, but it can contend with it.," All Might tells her. "From what I can tell, you're new...body-ahem-is already decently well trained. Though it seems you can't use that Quirks full power just yet."

True. While the body embarrassingly had more muscles that his male one before he trained, Izuku could tell the development was more towards some kind of martial art. Having made movements Izuku didn't want sometimes, but did because she 'remembered' and just suddenly made them. Body memory. So that made things slightly difficult as it made the mock training tough.

"I wonder if it'll help getting this person's identity?"

"Maybe." All Might shrugged. "But don't count on learning the identity anytime soon. I only figured out who's this body is because I'm the Number 1 Hero. An average civilian, well…" Izuku understood.

Since the swap, the entire government has been trying to tag who's who, getting people's DNA and then telling the newly swapped who's body they're in and what Quirk they may have. Her 'dad' along with herself already registered in the database, but it will take a while before they get results. A long while.

"And until then, I can't use this Quirks full power just yet." Izuku muttered as she looked at her hands. All Might having told her that the new Quirk she wielded could be comparable to One For All in some ways, meaning like All Mights former Quirk, it needed a proper vessel to show its true power. Izuku is only about above halfway there, with All Might guessing the Quirk she had is also a swapped one.

'Still,' Izuku clenched her fists. 'I have to try my best, or I won't be a great hero like All Might!' She just had to exceed her limits. That was all. Training up this body to meet All Mights expectations.

"AND GO!"

...Huh?

Izuku, and many others then turned around to where the voice came from. Seeing it came from the top of a building, where none other than the swapped Present Mic stood with a smile on his face. Looking down at them and yelling out, "WHAT'S WRONG? THE TEST HAS ALREADY STARTED, SO GET A MOVE ON FOLKS! HAHAHAHA!"

"Eh?" Izuku says, when suddenly the stampede of feet went past him with everybody running off leaving the poor girl shocked that it already started, and how slow on the uptake she is. Gasping, Izuku ran as fast as she could to catch up to all the students that were already ahead of her. Though it seems the damage was already done, damage to her score that is! Because already one-minute is up!

'Don't worry about this Izuku.' The girl tried calming herself, 'You have All Might backing you, and a Quirk that even he thinks is good.' She just needed to focus and find a faux-villain. Thankfully, her wish was granted in a terrifying way. For bursting through the wall while yelping, a green lean menacing machine came out with its camera eye staring at her coldly.

"A-A One Pinter!" One of the faux villains she needed to destroy. Right in front of her, just waiting to be punched. Instantly heading right at her with its arms out. While it was far from being the most dangerous and was rather fragile, one good hit and she'd be out. Not like her body was suddenly invulnerable and could handle such attacks, unless she used her Quirk.

'T-That's it!' Izuku thought as she realized what she needed to do. 'J-just need to use my Quirk. Use it. Use it!'

Yet she couldn't. Unlike with Kachan, where she just had to save him, there was no reason to attack. Not to mention this is Izuku's first actual fight in some ways. Thus her own instincts worked against her, with enough fear that paralyzed her entire movement. The One-Pointer ready to crush her into the dirt.

"I got you!" That is until from nowhere a pile of dark purple mud-like sludge substance came and attacked the robot. The goopy disgusting substance having a pair of philtrum, oval-shaped eyes with large, black pupils, and notably big teeth.

'That form looks...familiar…' It looked a lot like the Slu-

"Welp, uh, see-ya!" Then the goopy applicant left in a rush, leaving Izuku behind. Though not before it stared at Izuku for just a bit, notably at his chest before giving what could best be described as a blush and looking away ashamed. That was very weird.

"JUST OVER SIX MINUTES REMAINING!" Though weird is preferable to failing! Izuku gasped as she realized she needed to get those points right now! Realizing just how bad the situation is and had to get those points. Of course there was just one other problem in the list of problems she now had. Mainly, all the other students were destroying the other machines with ease!

To the right, to the left, the applicants crushed each bot without mercy. Rushing to where a new one is and getting their points. The scary guy with twin engines kicking some away. The goopy one from before wrapping itself on a heavy 3-Pointer and destroying it from the inside. Then he saw the girl from before who let loose a series of...Explosions?

"Ka...Kachan?" Izuku says as she watches the girl grin before moving on to the next bot. Though unknown to Izuku and everybody else, there were more eyes on them than they thought.

"Well then, this year's applicants seem alright." Sitting down in the dark room, the principal of the school says. "If anything, the only shame is that we don't have as many students as before. Though given the circumstances, it makes sense."

"If anything, we should have postponed this year's applicants." Another person growls. "It isn't rational to start a new year with this whole swap debacle."

"You're just mad because you got a body that's nice and sexy." A giggling voice can be heard with a hint of tease. "Now we're proper girlfriends."

"Shut it."

"Ignoring that," Another voice speaks up while touching his new leg. Having lost his old one in a battle with a villain, and still getting used to the new one. "Even with the swap, not everybody has a problem. Why, some of the students here are doing well with either their new Quirks, or thankfully gaining Quirks that were similar to their old ones."

"Still doesn't mean we should allow this." The self-proclaimed rational 'woman' growls.

"Regardless," The number 1 Hero All might grins as he watches all these future heroes do their best. "It's great to see that many won't allow even a small swap stop them from doing what's right."

"Say's the guy-rrrr-who kept his Quirk-ruff!" A man yelled at him.

"Uh...Why do you keep making dog noises?" A fellow teacher asked, adjusting his sweet cowboy hat.

"...Force of habit-grr." The man says.

"Regardless, let us continue watching our future students as they fight." The principal smiles while drinking his tea. "I look forward to seeing how they react to all this change." His hand then pushed a button. One that glowed red. "The ability to assess information, constant movement, make good decisions, and are good warriors. All that will be put to the test against this."

On a monitor, buildings could be seen falling as a great shadow loomed over them. A massive glowing red eye seen through it all. The staff of U.A. now watching to see just how their swapped students will react. All Might, watching one screen in particular of a young girl with a frightened yet determined look.

'Young Midoriya, good luck.'

The students who faced the robots were surprised, but not that surprised. Sure the robots were somewhat tough, and could be dangerous, but overall, many handled them with ease. For these were the students that decided to continue going to U.A., having advantages that helped them out with their new Quirks and bodies. Persisting in trying to be a hero.

Then that came out.

It was bigger than most buildings. It had hands the size of big houses. A single glowing red eye that stared into what they felt was their soul. Not to mention its very movement caused buildings to fall and the earth to shake. So naturally, in the face of such danger, many people did one thing.

Run.

"What the hell is that!"

"Shit!"

"Daddy!"

"Who can even fight that thing!"

"Mother of Quirks! Why?"

This, was the enemy they were supposed to avoid? Considering how big it is, it made sense! Many recognizing it from news channels of the military, a machine made to protect people in certain wars across the world. Heck, America had dozens of these things and it was said that other countries rent them from the country known for guns.

"This isn't even funny." Izuku says as she falls on her butt and starts crawling back. Many people moving past him as they to didn't want to deal with this massive threat. Heck, if anything one would only get hurt from it. Izuku herself slowly moving away fully aware that there was no point in fighting that machine. I mean, it's zero points anyway.

"I-I-I just need to leave. F-Find some other bots." Then earn herself points since she's still at damn zero! Her hands moving onto the ground and slowly getting up. It was bad enough she lost All Might's Quirk, and now she could lose her chance in U.A. High by being an idiot that didn't move. No, she couldn't let that happen.

"H-Help!" Izuku then heard a voice, and turned around. From there Izuku realized it was the girl from before, both at the entrance of the school and the one who created those explosions. She had a perpetual blush on her cheeks with large and round eyes, their irises a warm brown, with rather thick upper eyelashes, two longer and more prominent ones protruding outwards on either side and fewer but more individually pronounced lower eyelashes.

Shoulder-length and about the same color as her eyes, her hair is bobbed and curved inwards at the ends, two longer clumps taking the same shape on either side of her face, and short bangs that reach roughly a quarter of the way down her forehead. On the top inner segment of each of her fingers, she has a small pink pad, somewhat resembling the toe of a cat or a dog's pa while having a slender curvy body.

Who is now trapped under some rubble pinning her foot down. An angry look on her face as she then looked back at the rumbling machine and made a curse. Her hands making a slight explosion yet not doing anything as she looked so tired, like she wasn't used to this.

Yet there she is now, trapped with nobody to help. Most people having already left, with only her remaining standing still as she watched the giant Zero-Pointer slowly go toward them, with the girl in her path.

Then instantly, like with Bakugo all those months ago, she ran.

Inside the control room, All Might smiled.

Whenever the Zero-Pointer made an appearance, the great threat it represented always showed a person's true character. Being a completely overwhelming force that made the vast majority of students run instead of facing it. Only a few like him actually faced it, and even win against it.

But overall, many ran as there's no point in battling a foe that offered them nothing. In some ways, that was the right thing to do for some situations. While some might say otherwise, there is nothing cowardly about running from a villain that was stronger than them.

'But what will you do, young Midoriya.' All Might thought as he finally saw a screen where it showed none other than Izuku watching the giant Zero-Pointer coming towards her. Where another girl seemed to be trapped. 'Will you watch and run, and try to earn more points to save yourself.'

Izuku then saw the girl pinned down.

'Or, will you do something despite having no gain from it, and confront the challenge in front of you.'

'To show if you have the markings of a hero.'

The body that Izuku Midoriya has begun changing. The muscles she had growing a bit bigger and her own skin turning into a deep red while she felt her mass increase. Her appearance ever slightly altered with her physical stats now going much higher than normal people. Then, she stared up at the massive faux-villain and did one thing.

She jumped.

The girl with explosions, the purple goop, the man with the engine for legs, all of them and many others turned and watched this young girl go high in the air. Her form having jumped at such a great height, that she was actually above the bot and now falling down to meet it head on. The machine's red eye staring at her and gazed at the person in front of it.

As for the girl herself, Izuku stared at the machine while gritting her teeth. The words of her hero speaking to her.

"The Quirk you have may not be One For All, but even then it can allow you to match it. So long as you do one thing." All Might then stared at her and smiled and clenched his fist. "Clench up your butt, and yell this from the depths of your heart."

The right side of her tracksuit burst off as her slightly enlarged arm clenched it's fist. Narrowing her eyes, the girl then did as her mentor instructed her to do. Gathering the power of her Quirk, Izuku then met the machine and swung down her fist and yelled out one thing.

"SMMMAAAASSSHHHH!" Izuku screams as she then punches the massive machine head on. Her fist slamming into it so hard, that she felt more than just metal breaking. Even then, as for the machine, the force of the blow did its damage on it. The punch having caused a massive dent onto its head and destroyed the components while launching debris from it.

The punch having also caused massive destruction and even a chain reaction as explosions began occurring all over its body. Many gasped in awe while others were in plain shock at such a display of power. Elsewhere the Number 1 Hero just smiled at what he saw and smiled.

As for Izuku herself, she watched as the machine slowly fell onto it's back, and crushed all the buildings behind it. Still in the air, she just watched in amazement that she of all people managed to do that. Seeing the machine that could crush ordinary people now out of commission, because of her. It was incredible.

'And it felt exhilarating.' Izuku thought as she felt the wind flapping on her face. A bit surprised that once more, she moved like she did with Bakugo and where unlike then, managed to actually save the girl. All thanks to the Quirk she had been given, Muscle Augmentation. One of the simpler powers yet highly effective in what it does.

'And it feels great!' Izuku thinks as she feels her stomach surge uncomfortably from falling.

...Falling!

"G-Gah!" Izuku yelled as she finally realized at long last she was falling at a huge height. The red color she produced was gone and replaced by sheer horror at the speed she was falling at. At this rate, she'd end up turning red again. As a bloody paste on the ground!

Sh-she needed to use her power again. To use it and-!

Crrrri!

She then finally noticed that her legs were far from perfect and actually hurt, being all purple instead of the former red they displayed. Not to mention her own right arm which she used to throw the blow had ended up the same color and a great throbbing could be felt alongside another thing. One that made itself clear to izuku's mind.

"Owwwwww!"

Muscle Augmentation.

Like Gigafication, elemental based abilities, and others, it was known to be a common Quirk in this super-powered world. The Quirk itself gave a simple power. One that gives its user the ability to amplify, and to a degree, manipulate their muscles, granting a significant increase in strength, speed, and durability. When using this Quirk, muscle fibers can be enlarged to where they can no longer be contained by the user's skin. Granted, their are slight variants where in Izuku's case, it increases some of her muscles instead alongside mass, but still works the same.

'But,' Izuku thought as tears came from her eyes from the pain she was feeling. 'I only practiced this at safer levels. And I went overboard, and used the Quirk so much that it crushed my bones from the enlarged muscles.'

Up until the exam started and the swap occurred, Izuku only used the new power she was granted to practice with moving furniture and the like, not punching giant robots from this high.

'All Might said this body could handle 100% of this power...but I went above that and look what happened!' Now the after result is going to be her dying for getting so careless. Damn it all!

The ground was getting closer, her eyes widened and for sure she felt she would see her life flash before her eyes. Izuku then shut them and hoped this will be over quickly. Otherwise she'll spend the next few minutes in great pain before she died. Just now over a 100 meters left...50…

'This is it!' Izuku soon expected pain to enter soon after.

"I got ya!" Then from the ground, a purple goop slammed into her. It was gross, disgusting, and she felt the goop touch her skin and give her the shivers.

SPLAT!

Then, while obviously not dying, she felt the goop and her hit the ground in a nasty way. With purple slimy goo splattered all over with Izuku herself drenched in the stuff and on the ground with her broken bones panting. Her limbs spread out and she was unable to move while wondering what to do next.

"...Hi." She then saw two eyeballs on her chest and Izuku screamed.

"Wow." A girl with chestnut hair and a two flowered hair clip with a small chest then saw the two with chestnut eyes. "Talk about dramatic."
