Our story in this universe begins right after Izuku risked his life to save Bakugo from the Sludge Villain.

The pros were berating Izuku for risking his life, even though he saved Bakugo's.

"You idiot! Do you have a death wish or something?!" shouted Death Arms.

"You should've let us handle it, kid!" shouted Kamui Woods.

Izuku noticed that the other pros were praising Bakugo for illegally using his quirk.

"Your quirk is amazing, kid! When you go pro, you should intern with me!" said one of the pros.

After that Izuku went home. All Might saw him walk away and thought about following him.

'Maybe I should give him One For All. No, he was being too reckless. He can't be a hero. I should go see Nighteye now and meet the kid he recommended to give One For All to instead' said All Might as he went in the opposite direction.

A few minutes later, Izuku was almost home, when he heard footsteps coming behind him.

He turned around to see Bakugo running up to him.

"DEKU! YOU THINK YOU'RE BETTER THAN ME JUST 'CAUSE YOU SAVED ME?! I DIDN'T NEED YOUR HELP! AND I DON'T OWE YOU ANYTHING! GO FUCK YOURSELF!!!" screamed Bakugo before flipping him off and leaving.

Izuku then continued walking home. "Maybe I will kill myself" he said.

After that Izuku went back to the roof of the building he and All Might were on. He wrote a note and put it in his backpack. Then he left it on the roof.

He then climbed over the railing and looked over the edge.

"No one except Mom cares about me. I'll never be a hero. I'm nothing" Izuku said to himself.

And then... he fell.

Meanwhile with Bakugo...

As Bakugo walked home he saw a crowd of people up ahead. He moved through them all and saw that they were looking at... Izuku's dead body.

"Deku..." Bakugo said.

After that the police went up to the roof Izuku was on and found his backpack. When they looked in it they found Izuku's note.

After that the police went to Izuku's home. They knocked the door, and Inko answered it.

"Yes? Can I help you?" asked Inko.

"Mrs. Midoriya, we're sorry to tell you this... but your son is dead" said the officer.

"WHAT?!?!" said Inko.

"Yes. We're afraid he jumped off a building and took his own life" said the officer.

"NOOOOOOOOOOOO!!!!!!" screamed Inko in tears.

They then handed her the note they found in Izuku's bag.

"We found this in his bag" said the officer.

Inko read the note.

'Dear Mom, if you're reading this, I'm dead. I can't handle being quirkless anymore. Kacchan and his friends bully me, and the teachers don't do anything about it. Kacchan even told me to kill myself. And I met All Might today, he saved my life from a villain made of sludge. When I asked him if I could be a hero without a quirk, he said I couldn't. And then I saw Kacchan being held hostage by the sludge villain, you may have heard about it on the news already, and I risked my life to save him, while the pros just stood there and did nothing. Kacchan also used his quirk on the sludge villain, which is illegal. Then after All Might took down the villain and saved Kacchan, what did the pros do? They scolded me for endangering my life, even though I wasn't breaking the law. And what about Kacchan? The pros praised him for illegally using his quirk, just because he has a flashy one. After that Kacchan yelled at me again, even though I saved his life. Then I remembered when Kacchan told me to kill myself, so I decided to do that. I know this is gonna crush you, Mom. But I just can't take it anymore.

Goodbye, Mom. I love you.

-Izuku'

Inko broke down and started bawling her eyes out.

After that, the cops went to Bakugo's house. Mitsuki answered the door.

"Can I help you?" she asked.

"Mrs. Bakugo, we're here to arrest your son" said the cop.

"On what charges?!" said Mitsuki.

"For encouraging Izuku Midoriya to take his own life" said the cop.

Katsuki entered the room.

"So you're here to arrest me?" he asked.

"Yes. Do not resist" said the cop as he pulled out a pair of explosion proof handcuffs.

"I won't" said Katsuki as he was handcuffed and then taken away.

Then Izuku's death was announced on the news. The public was outraged that the pros scolded Izuku for saving someone's life, while they did nothing to help. And eventually it was decided that their hero licenses would be taken away.

Then came Izuku's funeral. The only people who showed up to it were Inko, Mitsuki, Masaru, and All Might.

All Might approached Inko.

"Mrs. Midoriya... I'm sorry for crushing your son's dreams" he said.

Inko spat in his face.

"You have some nerve showing up to my baby's funeral! All he wanted to do was help people! And you told him he couldn't! You're part of the reason he's dead! His blood is on your hands!!!" said Inko in tears.

Ten months later...

It was then the UA Entrance Exam. It was mostly the same as in the original show, except Izuku wasn't there.

Then the Zero Pointer robot was unleashed. Ochako was trapped underneath some rubble like in the show, but Izuku wasn't there to help.

"SOMEONE HELP ME, PLEASE!!!!!" she screamed, but it was too late... the robot had crushed her.

After that Ochako's parents tried to sue UA for getting their daughter killed, but she had signed a waiver, so there was nothing they could do.

Then it was the first day of UA for Class 1-A. Izuku, Ochako, and Bakugo weren't there, since Izuku and Ochako were dead, and Bakugo was in jail.

They were doing the quirk apprehension test. The person who came in last place was Mineta.

"Sorry, Mineta. Pack your things and leave" said Aizawa.

"NOOOOOO!!!" screamed Mineta.

"Wait, you were serious about expelling someone?" said Momo.

Then it was the attack at the USJ. Tsu was all on her own in the water area, since Izuku was dead, and Mineta was back in normal high school. The villains killed her.

Then it was the Sports Festival. Todoroki won, but he didn't use his fire, since Izuku wasn't there to help him get over his daddy issues, so because of this he went down a much darker path.

Then came the part where Iida went after the Hero Killer Stain. But Izuku and Todoroki weren't there to help him, so Stain killed him.

And eventually the League of Villains won. Mirio may have had One For All, but he didn't have the same wit and strategic mind as Izuku, so All For One killed him and the rest of the students and teachers at UA. And All For One ruled the world.

THE END

And that's one of the three possibilities I think would've happened if All Might didn't give Izuku OFA. I'm gonna do the other two possibilities next. Thx for reading.
