Origin: Part 3 of 4

I'm curious to see if any of you have any idea how Dekus quirk might work (It might be a little too obvious for part of it after this chapter). Also, this should help answer the question "Will Midoriya get One for All?" Feel free to leave any criticism or theories in the reviews at the end of the chapter (If anyone gets it right I'll be sure to mention whoever was correct when I publish the chapter it finally gets revealed in)

"Hey, wakeup! Hey!" Izuku opened his eyes to be greeted with a sight he never thought he would see. All Might, the real All Might, standing right in front of him. "Thought we lost you there!" Midoriya screamed before backing away from the mass of muscle before him.

"That was a nice distraction, blowing up the tunnel, but you might want to be more careful next time. Not to worry, I was able to capture the villain!" All Might held up two bottles, revealing the sludge monster had been contained. Izuku was so awestruck that it took him a moment to process what All Might said.

"Wait, blow up the tunnel." Midoriya turned and screamed, realizing the tunnel behind him no longer existed, instead a pile of rubble blocked the path. "No way! Was Kacchan here? Is everyone all right?" All might looked at the boy, his concern flashing across his face for a second.

"Young man, I assure you, you aren't in any trouble, everyone is safe. You don't have to act like you don't know what happened."

"Bu, but All Might, I'm quirkless."

All Might did a double take at that statement from the boy.

"That's impossible young man. I just saw you try to blow your way out of that sludge villain." All Might eyed the boy, seeing he was just in shock.

Could his quirk have possibly manifested now, at such an old age?

"Young man, I don't believe I got your name."

"Oh, it's Izuku, Izuku Midoriya!"

"Well young Midoriya, good luck with your quirk. Now if you'll excuse me, I need to get this to the police. Stand back, I'm taking off" All Might patted the bottles sticking out of his pocket before crouching as his prepared to jump away.

"Wait your leaving already?" He can't leave yet, I have so much I need to ask him.

"Pro heroes are constantly fighting time as well as enemies!" All Might gave that. With that All Might made a mighty leap into the air almost as if he was flying, sending out air and dust in every direction. "Thanks for your continued support!"

Midoriya fell to the ground where All Might had been a moment earlier. He tried to grab him before he left, but was too tired to move fast enough after everything that had just happened.

"Damn it" Izuku looked up at All Might, now just a small dot in the distance.

I had so much I wanted to ask him, like if I really do have a quirk, how do I control it. Can I be a hero like him? How should I train? Midoriya turned to look at the collapsed tunnel one more time. And most importantly, does he have any idea what my quirk is?

Taking a moment to collect himself Midoriya started making his way home, trying to figure out what he was going to tell his mother. He hadn't even made it halfway there when a large boom blew through the air from a few blocks away. He looked towards it to see smoke and fire rising from what looked like the shopping district.

Another villain attack? If All Mights there I might be able to talk to him!

Midoriya took off towards the fire just to see a shocking site. The sludge monster that attacked him earlier was facing off a group of pros, and winning. Explosions blew in every direction from him.

"It's no use, none of us have the right quirk to take on this guy!" the pro Hero Death arms yelled to the other heroes.

"Why aren't the heroes doing anything?" One of the bystanders asked the man next to him.

"It looks like they've met their match, plus it looks like the villain captured a kid"

Oh no, this is bad, this is really really bad. If this guy could escape All Might then that kid is in serious trouble.

Midoriya looked through the crowd of civilians to see another explosion go off, followed by Bakugous head resurfacing from inside the villain.

Before he had a chance to even process what he was doing Izuku was through the crowd and running through the flames straight at the villain.

"What the- no you idiot, you'll get yourself killed!" Death Arms dives for Midoriya, but he's long gone.

What am I doing? Why am I charging at him? Why can't I stop? The villain turned its attention to the one person still trying to stop him, expecting a pro hero, but instead greeted with the sight of the boy from earlier.

"You again, I'll crush you!" The sludge monster raised its arm, getting ready to kill Izuku in one hit.

What do I do, what do I do? What would a hero do? Midoriyas mind flashed to the notes he took earlier that day on Kamui Woods, make the opponent flinch and use that opportunity to restrain them. Page 25, right! Midoriya took off his backpack and threw it as hard as he could at the villain, hitting it in the eye. The distraction not only saved him, but loosened the monsters grip on Bakugou.

"Deku, what're you doing?" Bakugou weakly questioned Midoriya. Not expecting him of all people to be the one to save him.

"I don't know my legs, they just started moving!" Deku started trying to dig Bakugou out of the monster.

"I'm done playing with you!" The monster roared as it started to swing at Izuku again.

"Save the boy! This thing will kill him!" Death arms ordered the heroes as they all dashed after Midoriya, too far away to actually do anything to stop the monster.

Izuku looked up and covered his head, waiting for the blow to land, a blast of wind and a roaring clash filled the air. Deku slowly opened his eyes to see a giant of a man standing between him and the monster.

"I'm sorry you got stuck dealing with my mess young Midoriya." All Might grabbed Bakugou and pulled him out in one move as he readied his other fist to strike back.

"Damn you All Might!" The creature tried to swing with both arms at All Might, forgetting about Izuku.

"DETROIT SMASH!" All Might roared as he threw his fist forward at the villain creating a small whirlwind of force and literal wind that blew the monster apart across the entire district. When the wind finally calmed down the fires had all been put out for the most part as rain began to fall from the skies, helping the rescue hero Backdraft put out the last of the flames.

After being scolded by the heroes for his recklessness while Bakugou was praised, Midoriya began walking home again. He knew after what he just did he would probably never get the chance to talk to All Might now. Bakugou stopped him long enough to tell him that he would have been fine on his own, and didn't owe him anything before he went back to his own home.

At least I was able to help someone, even if they didn't want my help. Guess I should probably get home before mom starts to worry.

"I AM HERE!" All Might dashed out of a side street in front of Midoriya.

"All Might?! I thought you were with the reporters?" All Might let out a hearty laugh.

"I stand for justice! Not soundbites! Also I wanted to thank you."

"Thank me?" Midoriya repeated, even more confused than he already had been after the events of the day.

"You ran in to help that boy when the pros even faltered, myself included. If you hadn't stepped in I might have just been a helpless bystander as that boy was killed. You mentioned earlier that you didn't have a quirk until today, yet you still leapt into action, knowing you might die. You truly have the heart of a hero."All Might asked a now speechless Midoriya.

"That's not true! What I did was reckless, I didn't have a plan, I just got in the way more than anything else."

"There are stories about every great hero, how they began, and they all have one thing in common. Their bodies moved before they had a chance to think." All Might started sizing up the boy.

"Being a hero is all I ever wanted, but I have no control over my quirk, I don't even know what it is. How can I be like you when I can't even help myself?" Midoriya said mostly to himself, thinking about when he was engulfed by the sludge creature.

"You just need training, and I will help you with that. Remove whatever doubts you have in your mind. Young man, you can become a hero." Midoriya didn't know what to say, he fell to his knees crying. He had been told no his entire life, he was worthless, that he had no chance of being a hero. Yet here was the greatest hero in the world, saying he believed in him.

"Will you let me train you?" All Might said, stretching his hand out to Midoriya to help him up.

"Yes, of course All Might!" Izuku stuttered as he reached up and grabbed All Mights hand before everything went wrong. As soon as their hands touched Midoriya felt a massive build up of power throughout his whole body before he passed out.

"Young Midoriya! What's wro-" He saw All Might bending over him as his vision faded.
