(Btw, these alternate version aren't supposed to be taken seriously, these are just for fun)

"Hey, isn't All Might supposed to be here already, let me guess, he booked an interview" Aizawa asked 13

"Actually, the principal made a small change to the schedule. He asked him to take the Heroics class for 1-B in the morning, so that could spend the rest of the day here. Its 10:30 right now, he should be here by 11:30."

13 was about to say something when the lights began to flicker. Then a purplish mist began to appear near the fountain.

Both Aizawa and 13 felt something was about to go very wrong.

Out of the mist, a man covered with hands walked out, followed by a hulking creature with a bird like face. Then more and more villains began to appear.

"Stick together and don't move. 13, protect the students"

Yaoyorozu immediately understood what the situation was.

"Did the training start already?"

What is that thing?.... are those the people we have to save?" Kirishima was walking in front but was stopped by a steel staff.

"You heard Aizawa sensei, everyone stick together" Momo commanded sternly.

"And those aren't people we have to save.... they're villains" She said.

"13, get all the students outside, I'll deal with the villains" Eraserhead said as he put on his goggles.

"But, Mr Aizawa, your quirk isn't suited for situations like these"

"You can't be a hero with only one trick, Yaoyorozu. Don't worry about me and take care of your class" Aizawa said. As he was about to jump into the horde, he was stopped by Momo.

"I guess you're right.... you can't be a Hero with only one trick and that's why I'm going to use lethal force on them." Aizawa was confused.

"I don't understand, what lethal force?" He asked.

{Play Push it to the limit by Paul Engemann}

"Let's just say, I'm at my most powerful when I use lethal force.... Many people have mental blocks on their quirks to prevent them from killing people, I however, don't have that mental block. And besides they attacked us first, I think anything we do will count as self defence. And.... I won't intentionally try to kill them.... I'll just separate their legs from their body... "Momo said nonchalantly, both confusing and scaring the teachers and students.. even Bakugou.

'The fuck is she going to do?' Was what all of them were thinking.

"But I think it'll be better to give them a chance to surrender first." Momo said as she began to make a megaphone. After which she went to the edge of the stairs.

She announced.

But this was met by laughs and taunts from the villains.

"Hahahaha! What dou you think you can do little girl. I have something that can kill All Might" The hand man was laughing wickedly.

"They don't listen do they......" Momo said in a disappointed tone with a hint of anger.

"Well, no point in waiting....

Jirou, can you play Push it to the limit by Paul Engemann?"

"Y-Yeah"

"Ok, please start playing it now.... And someone please call for ambulances.... those villains are going to need them...." Momo said as she began walking down the stairs. As she walked down, her stomach began to glow..... but this time, instead of a megaphone, something very big came out. The students and teachers only watched... terrified as they saw what the thing was.

"Y-Yaoyorozu! Are you planning on murdering all of them?!" Aizawa shouted.

"Nope, I'll only destroy their legs" She said.

"M-May God have mercy on their souls" Kaminari said, trembling.

By this time, Momo had reached the bottom of the stairs, grinning at the villains with wickedness, holding her creation. The villains also saw what she was holding and were shaking and sweating.

After a few moments of silence, Momo spoke up.

"You should have listened..... So now...

SAY HELLO TO MY 7-BARRELED, HIGH TEMPERATURE INCENDIARY FIRING LITTLE FRIEND." She shouted as the barrels of her fucking MINIGUN began to rotate.

And at that moment, the villains knew... they fucked up.

After 7 seconds of warming up, she began firing as her body kept on producing bullets and feeding them directly into the gun, which was followed by screams of villains as their legs were being shredded and the wounds were being cauterized by the incendiary bullets.

Her classmates and teachers watched with wide and horror filled eyes as she defeated wave after wave of villains with extreme prejudice and gore.

"No! No! No! Nomu kill her!" The hand man commanded as the Nomu began to charge at her. She quickly changed her target and managed to completely shred the Nomu's legs, but, Nomu then began to regenerate his legs, shocking every one. For a second, Momo was also shocked... but quickly began to make incendiary bullets that burn with a very high temperature.... enough to carbonise cells. After which she turned the Nomu into a literal nugget, destroying its arms and legs.

The hand man was slowly being engulfed in the blank mist. Momo realised that he was about to warp out and so threw many flashbangs and stun grenades. Once she saw that the mist man was stunned, she proceeded to completely destroy the hand man's legs. After which she caught sight of the neck armor/device of the mist man. She quickly destroyed it... making the mist man unable to warp anymore. And in about 2 minutes, every single villain in the USJ were turned into moaning and groaning legless people. Then she walked up the stairs, trying very hard to keep her balance.

"13, do you have some vending machines in the facility?" She asked

"I'm feeling very hungry right now..."

But no one answered. They looked at her in shock and awe.

"Uhhhh, 13?" She asked again.

"R-Right... they're in the lounge, f-follow me.." She said as she led Momo to the lounge.

"WHAT THE FUCK WAS THAT?!" Bakugou shouted.

"I KNOW I SHOUT ABOUT KILLING PEOPLE ALL THE TIME, BUT THAT SHIT WAS TOO FUCKING MUCH..... EVEN FOR ME. SPEAKING OF WHICH, SHE COULD'VE KILLED ALL THOSE FUCKING PEOPLE IF HER AIM WAS A LITTLE TOO HIGH!"

.

.

.

"I.... I.... I.... I.... I...." Aizawa tried to say something, but couldn't find the words.

And after prolonged silence.

.

.

.

"SHE'S TOO OVERPOWERED!" The students exclaimed as Aizawa was still trying to speak.

(A/n please let me know which incident you want an alternate version of... also any type of art will be appreciated :P)
