"No, You-"

Aizawa looks at Izuku with the determination in his eyes.

The rest of the class looked at Izuku shocked that he asked that.

"I see."

...

"Alright, You take one side, I take the other"

The class is in shock, and thirteen yells "Have you gone mad Aizawa?! He is still a stu-"

"I Have a feeling that we will be just fine, Don't worry Thirteen, this kids limits are broken"

"From the looks of it, the only real heroes here, are thirteen and Eraser Head. Where is AllMight"

"Where is the symbol of Peace?! I cannot believe he is not here!"

"Maybe if I kill a few kids, he will show up and come to play"

...

"E-Eh Izuku what? and real villains? how did they get here?" Kirishima said

"The alarms aren't going off, thirteen why is that not happening?" Momo said
"I don't know" Thirteen replied

"That must mean's someone has a quirk that's interrupting the signal."

"Doesn't it."

"Thirteen get them out of here. Kamanari try to contact the school with your quirk."

Aizawa and Izuku leap into battle.

He takes them down one after another.

...

Aizawa blinked and the portal guy teleported to the door before the UA Students could escape

"Hello, We are the league of Villains, I know it's impolite but we invited ourselves in the home of justice"

"I cannot help but notice the symbol of peace isn't here, that's a shame, after all this is the perfect place for him to take his last breath"

...

Bakugo and Kirishima run at him

"You think we were just gonna stand there!?"

...

"I can't use my quirk, because of them!" Thirteen thinks to herself.

"Guess, I'll have to spread you throughout the USJ Then UA Students!"

"tch" Izuku gutters as he sees the rest of his classmates get taken away.

[Asui and Mineta are fine, they both ran away after they saw the situation, without Izuku there is no way they could get out of there without running]

Eraserhead takes down villains after another, both him and izuku working in synchronization, Izuku only needs one punch to take them down one after another, 

"Eraser! Let me go save the rest of the students, can I leave these guys to you?!" Izuku yelled

"It will only take a second!"

"Alright! Go!"

"He has taken out over half the enemies, but there are more all throughout the USJ, so it's logical to send him, I can handle the rest on my own."

...

"He runs to tsyuu and gets her and Mineta to the door, he does the same with all the others, instantly, one punching the last villain attacking kamanari, and getting them back"

...

"Kamanari? When did you become master saitam-"

"Actually nevermind."

Izuku looks back at the main quad and see's Aizawa's arm getting disintegrated.

"SENSEI!"

"Stay back! It's the main boss!" Aizawa shouts

"Wrong Hero, I am not the final boss" Shigaraki reveals

Nomu is revealed and starts parading Aizawa with smashes

Izuku looks in horror to see his sensei's body get repeatedly smashed, and then looks at Thirteen getting destroyed by her own quirk.

The one place he didn't go because he thought it was safe, the place he took his peers. Was one of the most dangerous places he could send them.

He made a huge mistake, or did he?

His classmates got Iida out, so now he could focus on the nomu.

...

Izuku looks in horror

"I can't stand here any longer, I must go!"

He rushes to the main battlefield just as shigaraki says

"let's go home kurogiri, It's game over" Shigaraki Replies

"But before we leave, let's make sure, the symbol of peace is broken, let's wreck his pride."

Shigaraki looks at Izuku

and rushes at him, while Izuku was in the air. He was about to touch him but Aizawa used his quirk before being smashed into the ground.

"Let's make this hurt!" He yells

"Nomu! Kill Him!"

Nomu rushes him, as they exchange hits, I can't just use my base strength anymore, I must be stronger, this villain is as strong as allmight, so I must use 100% Past my limits, to the extreme state!

"Serious Series"

The Ultimate Moves, Master Saitama taught me, that pushes my body past my limit, so far, that it can destroy mountains!

"Serious-!"

"Serious Barrage of Punches!"

The amount of force built up, the nomu couldn't regenerate

"Go Beyond!"

"SERIOUS SERIES! SERIOUSSS PUNCHHH"

The nomu was sent out of the USJ.

[ay 690 words nice]

Izuku's clothes were ripped from the punches, and he was able to defeat the nomu, the wind pressure slowly died down, as shigaraki was in pure shock, his nomu was defeated by a high school student!

"How... How How How! HOW DID YOU GET NOMU?!"

Izuku's body reached its limit, he broke his limits to much, he fell to the floor.

Shigaraki was about to touch Izuku, right before AllMight showed up. Shigaraki was in shock, he couldn't go up against AllMight without the nomu!

Kurogiri, and Shigarashi retreated. Izuku was unconscious, and his classmates were In shock from the pure power displayed by a quirkless boy. AllMight and the pro's cleaned everything up, and the day was over, Izuku's body went through so much.

[Thanks for reading, I hope you all enjoyed this new chapter, I enjoyed writing it, I remember all of you wanted Izuku to one-shot the nomu, and so he has. Now, would you like me to do the OVA too, or just move onto the next season?  The Ova is the one where AllMight is a villain and attacks them during training, Let me know. :D Also Older Heroes rewrite will be out soon!]
