Chapter One: The Quirkman Comeths

Izuku Midoriya was confused, to say the least. His dreams weren't usually endless black voids with a foggy floor.

No, this ten year old normally dreamt of things like Kacchan being nicer to him, or having closer friends than the lunch buddies or of meeting heroes and being a hero with some mighty quirk just like All Might had. It was colorful, it was happy, it wasn't so blah.

He knew it was a dream too, because where on Earth would you find a space like this? It seemed to go on forever, and he had no idea where the fog was coming from.

And then suddenly, he appeared.

A tall man in a black suit appeared in his dream, with slicked back hair and a smile that put the young boy on edge. He was walking confidently towards him, in a way that worried him. "Who are you?" Izuku managed to mutter out, slowly backing away from the advancing man.

"I am not here to harm you, young boy. I have come to fix a wrong and help you." The man paused as he said this, trying to be charming.

"Wrong? What do you mean?" Izuku didn't know what the man meant, he had never met him before. How could he help him?

"From birth, you have been unlucky. Cursed to live your days without the one thing the rest of us share. A growing anomaly in our society. To be born quirkless, what a shame."

Izuku's eyes lit up in recognition. "The Quirk Man!" Indeed the man was famous in the news for what he was doing. Something that All Might had warned them about. "You are the guy All Might said steals quirks and is evil!"

The man let out a soft laugh. "Oh dear, dear, it appears he has been spreading rumors. I don't know what All Might has been saying, but know I am not trying to steal your quirk. Rather, I want to give you one. How does that sound?"

Izuku was confused. Give him a quirk? He remembered what All Might said though and shook his head. "No, no way. You stole that quirk from somebody, and I don't want it! You should give it back! Give them all back!"

He let out a sigh. "Young man, I couldn't even if I wanted too. I have had some of these quirks for so long, their original owners died decades ago. Would you believe me if I said I got this quirk to enter dreams a century ago from an old man in the country? How do you expect me to give that back. No, it is much better that I keep these quirks alive, in me and in those like you who need one."

Despite himself, Izuku was amazed. Had the Quirk Man really lived that long? It didn't matter to him. "You still took it! You are a bad man. All Might will stop you!" Izuku began to stand up to the man. They were just in a dream, so it wasn't like the man could do much to him. Probably.

The man's smile turned sour. "You sure do love your All Might, but doesn't he make you mad? That this man can have a fantastic power, while you get none?"

Izuku stood his ground. "All Might is the best hero, so he should have the best power! And… and I don't care if I don't have a quirk. I'm...I'm …. I'm gonna be a hero, just like All Might!" Then he smiled.

All for One grew tired to this game. This child, this petulant child, refused his gifts so strongly all because of that man who was trying to ruin him. And he had a smile that was just like his. He didn't like it one bit. Here he was, sacrificing from his collection of powers gained over the centuries so he could seed the future for his successor Shigaraki. And this boy was trying to hinder him.

He had many quirks, more than a few taken on a whim or for a rainy day. There was one, decades old, that came to mind that had long outlived its usefulness for himself. But for this boy...it seemed like the perfect forbidden fruit. The exact thing that could turn him to seek out Shigaraki one day. A temptation that would bring him down roads that all led to him. His smile perked up again.

"Well then, future hero, I hope you enjoy the quirk I bestow upon you in your endeavors."

"I said I don't want your stolen quirks!" Izuku raised his fists ready to defend himself.

"Did you think I was going to give you a choice?" Izuku tried to sprint as All for One came towards him, but he easily caught up to the boy's pace. Grabbing him by the head, ignoring his struggles and cries against him, All for One plucked the quirk out of his soul and shoved it into the boy's. He would no doubt be hated by the boy but then again, with this quirk that was a good thing.

The youngest Midoriya woke up screaming. Things hurt. His head hurt. His muscles hurt. And his foot. His foot was in agony. He wished he didn't have a foot. His mother rushed in, scared at her son's outburst. Izuku couldn't calm down to explain, it just hurt so much. Quickly his mother left the room and through his own wails he heard her call for an ambulance.

The next ten minutes were of her best attempts to soothe him while he tried to get the pain to stop being so...painful. And luckily, it had begun to work. His head still felt like someone was using a jackhammer, and he wanted half of his foot to disappear, but he could think a little. And he could talk.

"M-mom."

"Yes Izuku! Do you what happened? How do you feel? Is it your heart? Your head? Your leg? Tell me Izuku!"

"Mom, the Quirk Man. He came to me last night."

His mom's eyes went wide. Of course she knew about him. Everyone did. The dream walker who was giving quirks to the quirkless. He would have been a modern Santa if All Might hadn't revealed how he got those quirks, and his evil past. Izuku would never know that for a moment, before everything was public, she wished for the man to visit her son, to let him reach his dream of herodom. But that thought was squashed when the truth came out. And after seeing the pain her son was in… she hoped All Might would get his hands on him soon.

"It's okay honey. It's okay. You can get through this"

"He-he made me take one. I said no, but he forced me." Another grunt of pain broke Izuku's attempt to calm down.

Inko began holding her son tight. "Shh, shh, it's okay honey. No one will blame you. It isn't your fault."

Izuku began to hug his mother back as he tried to control his urge to scream at his pains. "I-I don't like it. I know...I know I said I wanted to be strong but...but-but not if someone else is hurting!"

"I know, because you are a good boy Izuku. A good boy with a good heart."

"He...he makes me mad thinking all the things he did." He hugged his mother tighter as his mind wandered to the pain all those people felt.

Suddenly, his mother began to slap his arm. Looking towards her, she could she was in pain. Stopping his hug, he looked around to see what might have happened. Could the Quirk Man be back?

Inko caught her breath. "Izuku, I don't know what happened. But when you just hugged me, it seemed like you were gonna squeeze me in half! I think it might have been the quirk!"

He went silent, thinking to himself. He almost hurt his mom! Just cause of his quirk, he nearly hurt his mother. He cursed the Quirk Man, muttering apologies to his mother. He slammed his fist in anger on the side of his bed, mad at everything going on.

The wooden frame on that side made a loud crack as it broke and both boy and mother felt the bed become unstable. Quickly leaping up, Inko examined the damages and saw the bed had been broken on the side. It had been a sturdy bed frame she had just gotten him, there was no way it broke so easily.

Izuku was terrified. He nearly killed his mom, he broke his head, and his head still hurt and foot felt like it was on fire. What was going on?

Right on time the ambulance arrived, and they quickly took Izuku to the hospital. Once they heard what had happened, they took it very seriously and tried their best to help the scared boy and his mother to little avail. Once he got to the hospital he had some blood work done and was visited by a few doctors with specific medical quirks. Two police officers were there shortly after, to take a statement on what had happened and to make sure Izuku was alright. All the chaos had oddly relaxed Izuku, who felt less hopeless about his new burden and let him focus on willing the pain away that was leaving on its own slowly but surely. And, in spite of himself, he couldn't help but be curious. What was this quirk he now possessed?

…

"So, we ran some tests Ms. Midoriya and we have pinpointed what the quirk your son was given is. To put it simply, it allows the chemicals that are released by your brain when you feel angry to supercharge the muscles in your body to increase his strength, endurance, and durability."

The two Midoriya listened to the reveal in silence. It made sense considering what had happened. He had been angry and had gotten much stronger. But it was still a startling experience. It seemed so against character, that a nice gentle boy like Izuku was given such a violent quirk literally based around anger and hate. Then again, if they had more time to think about it, it made a twisted amount of sense considering how much the Quirk Man didn't like him.

"This is just a suggestion to put into the file based off of historical data, but we think the name "Anger Boost" best fits your quirk. I know this is sudden to ask Izuku, but does that sound alright?"

Izuku thought about this mismatched quirk he didn't want and could only nod. The name worked. Anger Boost. That was his power. The doctor kept talking to his mother, explaining about how the quirk adapting to his body created the pain from this morning. His pinkie toe bone fusing at the joint created the unimaginable pain he had been feeling, along with a few minor adjustments in the centers that created the chemicals Izuku used for the quirk. But he wasn't really listening. He was focusing on facts. The fact was, whether he liked it or not, he now had a quirk. A quirk that made him stronger the angrier he got. It seemed scary. It seemed dangerous, that if he didn't control his emotions he could hurt someone like he almost hurt his mom.

But it was a quirk. A strong quirk, from what he understood. And even if he got it from such an evil person, it didn't mean if it was a evil quirk. It was just a quirk. His quirk.

On the ride home from the hospital after a long day there, he made a declaration that he planned to keep.

"Mom, I promise to use my quirk for good! If I have to be angry to be a hero...then I'll be angry at all the bad things in the world! And I will fix them!"

Izuku Midoriya, the Anger based future hero, was here!

So this is the end of Chapter One! So the first few chapters are gonna be shorter like this, but expect more once I get past them. Not that these aren't important, but they are background for, you know, the UA stuff. And as my description suggests, this story is gonna be a lot different than canon in some aspects. All of the characters will be similar in personalities (but maybe not exact because of events) but there will be a few changes to them you will see. The big stuff is already being obvious, like All Might hasn't fought All for One like he did in pre-canon yet. And Izuku is now the Hulk. I am well aware of what I did, and I have no regrets.
