Yay! I don't know how long I have just had this sitting on my computer, but I decided to share! My first published fanfiction, so I can't wait to see what people think! I got the idea from a variety of sources, but mostly just from reading villain!Midoriya fics and thinking 'I want him to meet the canon Midoriya. So here we are!

I will update primarily on Archiveofour own on my account Itstheendoftheworldasweknowit (Literally the sentence: Its the end of the world as we know it But without the spaces.)

I also have a Tumblr! Username: Itstheend-oftheworld-asweknow-it

Alright! Well, please Read and review! Enjoy!

It was a normal day when it happened. Well, okay, not so normal.

Class 1-A was on a now-rare field trip out of UA with All Might and Aizawa leading them down the streets of the city.

They were supposed to be learning common places villains would strike, but what really ended up happening was a happy outing where they stopped for Ice-cream and enjoyed each other's company.

They were on their way back -on one of the less crowded streets thankfully- when the sky turned black and purple portals began opening and forming a wall around the heroes.

"Stay close students."

Aizawa's command was heeded and the students took a few steps closer to the two teachers, one of whom was also looking to Eraser Head for protection.

The crowd around the heroes (Not trapped within the circle of portals) cleared out quickly, a few cries of 'Get the heroes!' heard over the growing buzz of the portals.

The group was raising their fists, preparing for a fight, when Midoriya cried out in pain, clutching his head.

"Deku!" Ochako cried out, but when she tried to move toward her friend, her feet wouldn't leave the ground.

"Midoriya! What's wrong!" All Might called, also failing to move his feet toward his successor.

"Oh, don't worry." Heads whipped to the source of the voice. "It should pass in a few seconds."

The person in front of them gave a wicked smile.

"W-who are you?"

"Oh, it's not like you don't know the answer already, Toshinori Yagi, but I guess I can humor you."

The man stuck his hand out, mocking a handshake.

"I'm Midoriya Izuku, and I just got here from my dimension. Pleased to meet you."

The man -Midoriya?- took a few steps forward before tilting his head to the side, green curly hair falling into his wide eyes.

"What is- You're All Might, but you are not the wielder of One for All?" The confused face of the crazy man in front of them turned to pure glee, sending a shiver through the people looking at him.

His crazed eyes flitted through the group before landing on Izuku.

"One of these heroes is not like the other!" Midoriya cackled as he strutted toward his look-alike.

He was almost a yard away from Izuku when the air crackled with electricity.

Kaminari, the closest to the crazy man, had activated his quirk.

One moment before he was about to attack, a hand was holding his face.

"Now now now. Let's not start on such a bad note." Midoriya laughed as the electricity sparked into nothingness.

"What did you-"

The man ignored him and walked the rest of the way to Izuku.

"Now look at you! Midoriya Izuku! You must be so happy with yourself! The successor of All Might? The new wielder of One for All?"

Midoriya cupped Izuku's frightened face in his hands. "It's a shame that I'm still more powerful than you."

"Wh- What did you do to Kaminari?"

The grip on Izuku's face tightened before he was released completely.

"I figured you could have already deduced that be now."

Midoriya's hands lit up with yellow sparks.

"All for One?" The whispered question of Toshinori shook Izuku to the core.

Midoriya spun around with his hands above his head. "AND HE SCORES! Honestly, how you became the number one hero is beyond me."

When he came to a stop he was facing Bakugou, and his crazy smile dropped.

"You know, when I was nine," His voice was casual but loud enough that everyone could hear, though it was obviously directed at Katsuki. "There was this boy I knew. He was strong, unbelievably so, and I looked up to him. But he would always tell me I was worthless. That I would amount to nothing. That I couldn't be a hero. And one day, I listened and I realized he was right." Small explosions flashed in the man's hands and illuminated his face from below. "No one ever said I couldn't be a villain though."

"Why are you here?" Toshinori asked, directing the attention away from a low-key panicking Bakugou. "What do you want?"

"Interesting question, Toshinori Yagi. I could answer, if you want. But not here. If you are truly curious, you and your successor could come with me. Have a chat over some tea and talk like old friends." The feral grin on the green haired man's face told them that if they went with him that is not what they would be doing. That grin promised pain.

"They won't be going anywhere with you."

"Oh, is that so Aizawa?" The man let out a giggle as he got up in the teacher's face, his next words coming out in an angry hiss. "I have an army on the other side of those gates. All it takes is a word from me and I let them come through and slaughter the city." He leaned back and he was smiling once again. "But don't worry! I would let you watch, of course!"

Aizawa opened his mouth to retort, but he was cut off by Izuku.

"Wait! You, you just want One for All, right? You wouldn't even have to take All Might! Just take me!"

"Tempting, but I'll have to decline. You see, I still have unfinished business with All Might."

There is silence among the group. (there are now heroes struggling to get into the circle of portals and they were all shouting, but no one was successful.)

And then, suddenly, Midoriya's amused expression turned pained and he cursed under his breath.

"Ah shi- alright, times up. You're all coming with me."

He waved his hand and the portal wall closed in, covering them in swirling darkness, and when they opened their eyes, all they saw was black.
