(3rd Person)

To sum it up in simple words: Karma was so not ready for this, she rose out of the rubble covering her, going wide-eyed at seeing a seething (Y/N) glaring right at her. Once she made herself known, it seemed as though (Y/N) was more alive than ever, dashing off from his spot at impossible speeds, even leaving quite the massive crater in place, next thing she knew, her insides felt almost as terrible as when (Y/N) used his quirk on her, she couldn't look down in time as whatever hit her sent her flying, she even broke the sound barrier three times in a row before feeling something hit her back down to earth.

Karma gasped out in pain, her blood spraying from her mouth, but she couldn't recover as she felt someone grasp her head, squeezing tightly before slamming her into another fake mountain, only for said fake mountain to shatter into dust from the power behind the slam. As Karma tried to look once more, she wasn't prepared for a punch straight to her spine, she could swear a crack was heard before she was once again sent flying breaking the sound barrier a total number of five more times...

Meanwhile, everyone else, even the villains had stopped everything they were doing and were wide-eyed at seeing what they saw in their eyes to be a girl in a black cloak being thrown around, breaking the sound barrier everytime she goes flying and whenever she gets close to being knocked out of the USJ, something hits her again to make sure she stays inside. The only people who were able to catch a glimpse were Sofia, Mark and All Might had to squint his eyes, but he saw (Y/N) appear and attack Karma all the time.

Speaking of Karma, she was now sliding face-first through the floor which stopped when someone stomped on the back of her head, sending her further into the ground before said foot punt kicked her out of the ground and slamming her through the fire dome which had Ojiro inside fighting for his life, he was surprised when he saw someone fly through one side of the dome and through the other... even the thugs stopped suddenly and were staring at the two holes with confusion.

Back to the punching ba- I mean Karma, she's currently breaking another sound barrier causing again everyone to try their best not to get taken off their feet, Karma was lodged into the stairs leading to where Thirteen previously battled the warp gate villain along with the other students, only... Iida wasn't there since earlier he managed to escape and was currently on the way to U.A high to request reinforcements.

Mark: Geez... no one's insulted his scarf in the last three years, so I never thought I'd ever see this.

Eri: (Y/N) doesn't like anyone being mean about his scarf?

Mark: Yep, one bad word, even if it's unintentional, and he'll stop holding back his strength and make sure you regret the words... I... am afraid to admit I accidentally insulted his scarf as well... it's where this came from.

Mark lifts his shirt to reveal what seemed to be a fist-shaped scar on the left side of his chest, Eri went wide-eyed at seeing it, wondering just how strong is (Y/N) to be able to cause such an injury.

Mark: He hit me hard, so hard in fact that he actually punched my left lung out of my body, blew a hole in me that took months to re-stitch, the funny thing is: he didn't even apologise once, just went back to normal the next day as if nothing happened... he may be my best friend, but... he scares me sometimes so I make sure never to piss him off.

They both jumped when Karma was suddenly in front of them, her hands desperately grabbing Mark's leg as she looked up, her face deformed with obvious missing teeth, a barely open eye and the nose so twisted that you'd swear it had done an almost full circle around her face.

Karma: O-ok... I... I love pain... but, even I know when it's too far... so, I know it's a lot to ask... but...

She yelped when she felt her ankle being gripped tightly, she looked back in horror, only to see literal fires in (Y/N)'s eyes while his teeth became pointed.

(Y/N): I'm not fucking done with you, bitch!

Karma turned back, tears appearing in her eyes as Mark simply smirked in amusement.

Karma: Help...

Karma was quickly tossed away, this time breaking the sound barrier a total number of 12 times, this time (Y/N) didn't stop her as her back harshly slammed against the wall of the USJ, this time she heard a harsh snap instead of a crack.

(Y/N): So... which bone to break next, huh!? Tell us bitch!!! Which bone's next huh!?

All Might: Y-young (L/N)... so scary...

Deku: Is this... what he's like when angry...

Kirishima: It's even worse than Bakugou.

Bakugou: The fuck you say!?

Everyone watched as (Y/N) grabbed her arm, harshly slamming her back into the ground before tossing her away, then running after her before he grabbed her face dragging it across the entirety of the USJ... anything that looked or even resembled a wall he'd be dragging Karma's face through it.

???: And I thought you heroes were supposed to be training future heroes...

All Might: Well... we do have exceptions we can't control... I believe there is a rational explanation for his anger...

As he said that, Karma went flying past them once more, this time slamming into the dark-skinned creature which caught her out of instinct... only to realise its mistake as it looked up, only to see (Y/N)'s angry and terrifying expression, his right fist reared back and veins popping up all over his forehead.

(Y/N): Don't get in my way jackass!!!

He punched the thing and to the surprise of everyone who knew the thing's quirk, the dark-skinned creature went flying, breaking the sound barrier twice before it landed in the water while Karma stayed right where she was, until (Y/N) grabbed her by the throat, slamming her into the ground with minimal effort while it created a massive shockwave and crater, knocking away even All Might... although it was only a tiny bit.

(Y/N): Time for the real punishment! This is your end!!!

It was like a finishing move in a video game: (Y/N) started with slow punches to the face, each one causing the crater to grow deeper as Karma's body went further into the ground... All Might watched in fear as the punches got progressively quicker and stronger... kicking up a whirlwind and shockwaves as slowly he couldn't keep track of (Y/N)'s punches since his arms turned into blurs, flurries of punches being delivered to the villain as she continued to dig herself a deeper grave by using her body... eventually, All Might had to jump back in fear of being blasted away while everyone else held their arms up, protecting themselves from being blown away.

Then, everyone saw it was finally going to end when (Y/N) stopped temporarily, raising his right fist high before quickly bringing it down, caving Karma's face in as the ground literally exploded... the massive shockwave instantly pushing everyone away as even All Might went flying even with his arms crossed. The only ones unaffected were both Sofia and Mark, Sofia who was simply running back with no problems and Mark who stood still with Eri clinging onto his leg for dear life.

The smoke dissipated, and Mark was the first on the scene: casually walking up to (Y/N) with Eri by his leg, scared (Y/N) was still angry... Mark let out a whistle of amazement seeing the massive crater (Y/N) caused, Karma all the way at the bottom with blood all over her face... luckily since everyone would probably throw up from how disfigured it looks. Without any fear, Mark slid down the crater and then landed behind (Y/N), placing a hand on his shoulder.

Mark: Calmed down now buddy?

Tense silence as some people were brave enough to look down the crater, until (Y/N) turned to face Mark... his usual emotionless expression back on his face making even Mark sigh in relief seeing as how he's calmed down.

Mark: Don't you think you went a little too far? No way is she going to get a boyfriend with that face anymore...

(Y/N) shook his head, punching her again even while looking away... he hummed when he heard a squelch and moved his fist away to see blood, Mark sighed, placing a hand on his head while shaking it.

Mark: Come on now, she's obviously had enough, even I feel bad for the villain... besides... you're scaring Eri.

Though, it seemed his words weren't true considering once Eri saw (Y/N) was not mad any more, she went back to her normal expression as she walked forward, poking (Y/N)'s nose while a pout seemed to appear on her face.

Eri: Don't get mad anymore, ok?

(Y/N) nodded, grabbing Eri and leaping out of the crater with Mark standing there feeling dejected that he was just ignored, but he quickly got out of the crater too.

Sofia: So, you finally calmed down now?

She was walking up to them with her hands on her hips, sighing while crossing her arms, Mark however didn't seem amused at seeing her.

Mark: And where were you supposed to be?

Sofia: Oh shut it weakling, I was doing everyone a favour.

While they began to argue again, (Y/N) finally realised the wounds he had and instantly fell on his face startling the two as they saw Eri start to panic, shaking (Y/N) while tears went down her face... that made both Mark and Sofia grow deadpan expressions.

Sofia and Mark: Isn't your quirk supposed to heal him...?

Eri: Oh...

With that, her tears were instantly gone and she placed her hands on (Y/N)'s body, making the injuries slowly disappear... none of them noticed however as a bloody and broken hand clawed the ground behind Eri... nor did they notice the dark-skinned creature rise out of the water... luckily, a certain hero did as he went wide-eyed from seeing the dark-skinned creature head right for (Y/N).

All Might: Young (L/N)! Move!

Everyone was surprised that when the creature attacked, (Y/N) and Eri had suddenly teleported to the edge of the crater... just in time for the bloody hand to clutch Eri's foot...

Karma: I... finally, have you... (Y/N) (L/N)... Wait... Eri?

Eri just screamed, shouting how there was a monster while using her free foot to continuously kick Karma in the face, trying to pry her off her foot... Mark and Sofia simply scoffed into their hands, snorting in amusement from the funny sight... that was until they saw Karma's malicious grin.

Karma: Hehehe... even if it's a kid, I'll still use it! Here we go!!! Cheap Trick!!

Eri went wide-eyed, she remembered exactly what Karma's quirk was and closed her eyes in anticipation... only to feel nothing as she slowly opened her eyes to see a confused Karma looking at her bloody hand.

Karma: W-w-what, why... why doesn't... it work!?

Sofia: Probably because of my quirk.

She gasped in surprise when she looked up to see Mark and Sofia glaring down at her, but... her smirk grew once more, foolishly gaining confidence.

Karma: I'll... just try it again... Cheap Trick!!!!

But again... nothing happened, she looked down at her hand again in confusion at seeing it still bloody and broken... only to catch something out of the corner of her eye... she however went wide-eyed in confusion at seeing it.

Karma: W-what!? E-e-e-Eraserhead!?

Sure enough, the pro hero was standing there, hands in his pockets while his hair was up in the air with his eyes glowing red from using his quirk.

???: Impossible!

Everyone turned to face the hand man, his expression one of confusion and disbelief while his eyes were wide in anger as he ferociously scratched his neck leaving blisters.

???: He was taken down by Nomu! But, how!? How is he even here!

Sofia: Well... it's not technically Eraserhead... though it's quite convincing isn't it?

???: What!?

Sofia: It's my quirk... I can clone anyone as long as I look straight at their eyes... in this case, I ran off to make sure our victory was secure by making eye contact with an unconscious Mr Aizawa, creating the clone which had been using its quirk ever since I saw that disgusting hand grab little Eri.

???: No... it's not fair... it's...

He was cut off when a shockwave was formed... then a bunch of them from behind him as everyone followed the villain's gaze to see All Might once again taking on the creature, only this time he seemed to be gaining the advantage since his multiple punches were pushing it back.

Mark: Now then...

Karma gasped, looking back up to see now all three of them were staring down at her, (Y/N) cracking his fully healed knuckles, Mark sporting a grin while Sofia simply glared into Karma's soul... however, all three of them suddenly reared their fists back.

Sofia: It's about time you head on home... weakling villain.

All three attacked at the same time as All Might delivered the final punch to the Nomu, both Karma and the Nomu were sent straight out of the USJ with the four heroes... well, one hero and the other three were in training smile victoriously at their easy or hard-earned victory.

Mark: Welp, I'd say that wraps things up here... don't ya think?

Sofia: Not quite yet...

Mark: Oh yeah...

The remaining villains watched as the three turned, their auras of power quickly overwhelming them as they had fires in their eyes again.

Mark: We still have to deal with these pieces of trash too...

All Might: No... go on ahead, I'll deal with them.

Deku: No... don't go... if you go then All Might... he's already out of time... stay with him... stay with him, please!

Deku whispered that from hearing the conversation, however, it seems he wasn't able to get a granted wish since they all seemed to agree with (Y/N) grabbing Eri and disappearing suddenly, allowing All Might to breathe a sigh of relief... but then his body start to smoke... luckily that smoke blended in with the smoke from his battle with the Nomu.

(Timeskip)

Luckily, everything turned out fine as the backup came in time to save everyone who was in a spot of trouble... as for the three powerhouses, they were currently together, huddled into a triangular circle while Eri was on (Y/N)'s shoulder.

Mark: Man... you do know if Karma never insulted (Y/N)'s scarf we all would've been worse off, right?

Sofia: That and little Eri's quirk... if it wasn't for her... then we wouldn't be standing here.

(Y/N) nodded, reaching his hand up to ruffle the child's hair who hummed in satisfaction from the praise and reward which made all three of them smile widely...

???: Excuse me...

They looked to see a man who looked like the lead detective, only... his face seemed extremely serious drowning the happy atmosphere immediately.

???: Are you three... the extra students... who are a part of 'that' project?

When all three nodded at the same time, the detective sighed, placing a hand on his hat and taking it off, before he placed it in front of him with his grip tightening.

???: They've decided... the date's been hurried... the experiment will begin tomorrow.

At that, the three went extremely wide-eyed, mouths almost hitting the floor while Eri tilted her head in confusion... the detective placed his hat back on his head, bowing to them.

???: I'm so very sorry... I hope you can all come out of this safely... and... thank you...

He walked away, causing Eri to believe the happy words would come back... only to grow a dreadful silence as all three... even (Y/N) and Sofia seemed to look down with pale faces, their expressions filled with dread as they looked up at each other...

Mark: T-they hurried the date... but... that means...

Sofia: Something must've happened... to cause them to suddenly want to go through with it... even if they're not fully prepared...

(Y/N): 'Guys... I... I don't think...'

Mark: It's alright... we'll... definitely... definitely...

Eri: Umm... what's wrong?

(U.A staff meeting room)

Nezu: I hope you all can agree...

Midnight: Of course we do... it's just... to entrust this power to those kids so early... don't you think?

Cementoss: No, Midnight, if anything now's the best time... they've shown just how powerful they can be.

Nezu: Indeed...

He presses a device, turning on the projector as it showed multiple photos of when (Y/N) was in a rage induced state and beating down Karma mercilessly.

Nezu: If (L/N) is capable of such damage while in anger... I'm more than confident the other two can be just as powerful too.

Ectoplasm: But still... can they... will their lives be ruined by this?

Silence in the room, no one dared answer, even the cheerful principle didn't speak up as his gaze met the floor, regret and guilt already filling his thoughts while he unconscious pressed the button for the next slide... the project's name and description on full display.
