The Silent Quirk

In ten months it would be time for the UA entrance exam, one that Izuku had prepared for his whole life. And yet he wasn't ready yet, not at all. While he had novels of notes on heroes, their quirks and their potential. While he had pushed himself to be top in their class in all but PE. While he had steadfastly studied everything he could about hero life in preparation. There was just one problem.

He was still quirkless.

The doctor had said he would never manifest a quirk, identifying a toe joint in his foot. But that was before All Might, before One for All. It just hadn't manifested yet, a quirk of this power would take a long time before he could use it.

Even if it took a week or a month or a year it would manifest eventually. Right?

Maybe today would be the day when One for All activates, they had a gym session today and it would be a good give it another try. All Might believed in him. He had to do it. He couldn't let him down.

As he jogged through the streets though he noticed that wherever he went a strange man seemed follow him. The man was pulling a large suitcase by the handle, a very advanced looking suitcase. No matter how fast Izuku ran or what way he went the man followed him. It was strange.

But he didn't have the time to confront him about it, UA's entrance exam was but ten months away. He had no training. He'd never been able to use One for All. It had to be today, after all today they'll be applying for their high schools.

This is his day.

He reassured himself of that when he ran through the streets eager to arrive nice and early for the school day. Nothing would stop him, not today, not ever.

But as he ran he noticed a hero fight, the Lurkers were facing a large villain with bat wings. He couldn't help himself but watch, this would be the first time he could document their quirks. Besides he had time, he had overestimated the distance. So instead he scrambled around for a notebook excitedly, and was ready for the ensuing fight.

Kamui woods began the battle with his ultimate move, attempting to trap the villain in his vines, but the creature seemed too fast. Easily escaping the trap, and keeping just out of range. The villain was trying to flee, and Mt Lady was giving chase. She was using her air clap attack to throw him out of the air.

"Ugh stay still you creep" she yelled as she missed again.

"Not a chance hero. You're too slow" the villain laughed as Mt Lady's attempts to slap it out of the air only resulted in bursts of wind flying through the street.

There was a loud thump, and Izuku turned to see the man from earlier struggling with his briefcase which seemed to have tripped in the wind. He seemed to struggle to get it back up.

"Do you need some help?" Izuku asked, rushing over to him. The man seemed to jump at his voice, shaking his head quickly.

"No, no I'm fine. I never knew that Mt Lady could do that" the man said, he was fairly short as things went, his hair a scruffy green and his eyes seemed heavy with exhaustion.

"She's been able to do that for a while. Her air clap move is one of her signature moves" Izuku explained, he was getting his notebook out to show him.

"A move like that would cause a lot of collateral damage though" the man noticed, he was right many times when she had used it had shattered windows and buildings.

"It can do but part of her quirk is that she can reduce the impact of her body when she's enlarged" Izuku explained showing the man the relevant page his eyes rounded to the size of saucers "she uses that to reduce the damage her quirk could cause, otherwise she'd create holes in the street"

The man's eyes seemed to bug out of his head at that statement, and he just stared dumbfounded.

"She couldn't do that… is her quirk stronger here? Or is it an isolated incident?" the man began to mutter.

"Erm so yeah, are you a hero fan too?" Izuku asked and the man smiled.

"The biggest fan" he said, causing Izuku's to smile widely. Only to be interrupting by MT Lady's groans of frustration.

"Damn it he's slippery" Mt Lady growled "we're going to have to-"

At that precise moment a green, wispy circle appeared right in front of the bat villain. In the next instant the villain flew into it disappearing.

"Call for backup" she finished, stunned like a deer in headlights. The entire crowd looked around in confusion, except the man Izuku was talking to who simply sighed.

"He's here"

Turning he saw the bat villain held up from behind by a hero. The hero had an abnormally muscular arm that seemed to have bulged out of his skin. The hero himself seemed familiar, wearing a dark green helmet that covered his full face. Though it was mostly transparent, the only truly hidden opaque covering his eyes like a domino mask. He wore a dark green and white suit with a long cape that descended to his waist.

"I apologise for stepping in. I know you would have been able to handle it, but I despise it when villains hold up the morning commute" the Hero said, he clutching the villain tightly.

"Who… who are you?" he gasped, the hero behind him had him quite a grip on him.

"I am part of a new team of heroes. Call me the All for One Hero: Reformer" the man announced "now if you excuse me"

In the next second the bat villain disappeared and in his place was only a blue marble remained, one that the hero swiftly caught. As he did so his arm reduced in size to that of a normal arm. Smiling another portal appeared behind him.

"I have to be taking this man to the police now. But don't worry if there's any trouble, I'll be there" he promises waving as he opens another portal behind him and stepping through it.

"Well that was random" Izuku muttered. Who was that? And what the heck was his quirk? He couldn't think of any ability that would allow one to open portals, shrink villains and some kind of super strength.

"Hey" the man next to him said "you should probably head to school. You don't want to be late"

"Oh right yeah" Izuku said as he rushed past him, going at a sprint to his school that day. The new hero on his mind, he said he was part of a team. It was rare that people started with hero teams out of the gate, especially as this hero hadn't been a sidekick to any hero he knew of. And you would expect a hero like that to raise attention.

He was well out of sight when the man behind him disappeared into an alleyway. Then the man pressed a finger to his ear.

"He saw me, he even talked to me. He's headed to school so that counts for something I guess" he said before pressing a button on his suitcase. Instantly it began to unpack his armour. Advanced even by superhero standards, every bit the match for the strongest of quirks and more versatile than all but all for one.

"That's good. Even in a worst case scenario he'll be unable to interfere without arousing suspicion" Eternal Flame answered "if he's at school I hardly think he can manage a criminal empire, even if he could he wouldn't be able to do anything to stop us"

"That's true" he responded "thanks for the help Reformer"

"Next time make sure to equip you suit. Speaking of which Firstbreed get it equipped, if Izuku's not a problem then we should get to work"

"Agreed"

As he stepped into the boots of the armour, the machines came to life. The suit of armour began to cover his body until he was finally encased. Finally the AI program began to activate.

"I AM HERE AS AN AI"

The All Might voice pack was a decision he never regretted. Espically since he'd gotten All Might to record it himself.

"Armed and ready. Let's go"

Fifteen Minutes Later

Izuku arrived on school just before the bell, still feeling the rush from that villain fight. The new hero had his mind whirling for the entire trip. As he entered his classroom though he started to hear conversations about other heroes abound.

"That's another of the Green heroes right? That's the third one right?" one of his classmates said.

"Yep four villains and they only debuted 15 minutes ago"

"Any idea of what their quirks are?"

"No idea. Only one we heard about is one of them saying he was the 'All for one hero'. Whatever that means"

Izuku resisted the temptation to rush over to them and gush about what had happened earlier that day. There would be no point, and he would be intruding on their conversation. He didn't want to intrude.

It didn't matter much anyway for at that moment the teacher came in and he was forced to focus on schoolwork. He turned his phone off during the day but he still heard snippets from his classmates.

By lunchtime however the rumours had gotten out of hand, and he took his lunch to the furthest available spot from human contact where he started to research them.

There were three of them, each wore green outfits, hence they had been dubbed the 'Green heroes' online. In the time since he'd arrived at school and now they had made over forty arrests. A record for a hero's debut only challenged by All Might himself. The first of these heroes was the All for one hero: Reformer, the same one he had met earlier. He had shown several other powers already including cloning, some sort of decaying quirk and the ability to disintegrate and reform objects. There was possibly more.

The second was called Eternal Flame, some sort of enhancer quirk but one extremely powerful. One that might surpass All Might himself. The two were extremely similar, even sporting a similar smile and outfit. Though his was a lime green and white with a rabbit mask.

Could he be related to All Might? Maybe he knew something about One for All? Could Izuku get in contact with him? All of his attempts to reach Sir Nighteye had failed, him being dismissed as an overzealous fan. Perhaps this hero would be more willing.

But the third one was perhaps the most fascinating, from head to toe he was covered in some kind of power armour and support gear. The man had shown no sign using their quirk and rumours about his mystery quirk were popping up. Some suggesting he had some kind of intelligence or analysis quirk.

But he might be quirkless.

"WHAT THE FUCK DID YOU SAY DEKU?" shouted Kacchan, causing him to jump. He must have been mumbling that out loud.

"It's just since Firstbreed is using a lot of support equipment and no quirks I thought he might not have you" he muttered even as he was screaming at himself to shut up to not annoy Kacchan.

"There are no quirkless heroes Deku. There never have been and never will be. You got that? Heroes are strong. Quirkless people like you are weak, worthless nobodies" he snarled, firing off a small explosion in his hands.

"Kacchan I'm not quirkless" he said, but Kacchan just laughed in his face.

"Oh right the quirk that mysterious hero said he'd gave you. The one that you've never used in fourteen years. The one that you still think you have even though all the doctors said you were just a quirkless nobody" he mocked and Izuku shrank into himself.

"You're wrong Kacchan" he muttered, it had been a mistake to tell Kacchan about his given quirk. But he never explained the nature of One for All nor that All Might gave it to him.

"If I'm wrong why don't you use it on me? Right here right now" he dared him before shoving Izuku to the ground. As he pulled himself back up he noticed that Kacchan had taken his notebook out of his bag.

"Still wasting your time trying to be a hero? It'd be better for everyone if you just accepted you'll be nothing but a loser in this world" Kacchan snarled, blowing the notebook up in his hands.

Something snapped. Izuku charged, pulling his fist back. Just like All Might did.

"TEXAS SMASH"

He hit Kacchan square in the jaw, making him stumble back a few feet. But there was none of All Might's power behind it. No One for All. No quirk.

"Pathetic" he growled before throwing Izuku back with an explosion of his own. Izuku didn't get up, he just tried to not show the tears welling up within him.

"It's time to face reality Deku. You're useless. You don't have a quirk, and any hero who told you otherwise was lying to you. Or was just insane. And you're an idiot if you believed him for a second. You have no quirk. You never will" he shouted, then left leaving Izuku on the ground to whimper in his own pain.

All for One

When you walked as a lion among sheep there were few things that truly terrified. In fact the feeling of fear was one that was one that All for One had forgotten since his defeat of All Might four years ago. But now in a series of hours that feeling had returned to him.

In less than a day these new heroes had been targeting his criminal empire, arresting and disrupting his operation across the country. More worryingly was the coordinated effort behind it, how they seemed to know exactly where the evidence was to uncover and where his subordinates were and what their weaknesses were. How long were they investigating him? How much did they know?

For a criminal being completely exposed was fatal, his empire could fall within a day.

The quirks themselves made him afraid, the one called Eternal Flame seemed to have One for All. Did All Might secretly cultivate a successor? He was impressed that the man had hidden him for so long, he didn't think it was possible.

The other one 'Reformer' was more concerning for he had his own quirk. He also seemed to have abilities similar to his own subordinates, he had not known that his quirk was shared by another. Worse that person had allied himself with the One for All user.

He'll need to relocate our operations and move into hiding. His whole operation was on the verge of collapse. But he might not have enough time. Already in but a day eighty villains had fallen to these new heroes. Many of them very powerful themselves. It would take an All Might level threat to buy him enough time.

"Bring me Shadow Master"

A/N: So I'll be frank I struggled with this chapter as I wondered how best to introduce the extra-dimensional Izukus. I'm not sure this chapter worked well seeing as we only saw one of them in action and one other in person. Yet on the other hand I felt having them go on a rampage through Japan using their hindsight to cripple All for One's empire along with some other villains (though many will have been saved from the butterfly effect) is a decent way to show them as capable. Though we'll get to see them fight in the next chapter.

Also so people's quirks will be getting a boost in this story, there's a reason for this. I want the other Izukus to be powerful not broken. How powerful other people will be will again be explained as they are introduced.

Hope you enjoy and feedback is always appreciated, as are suggestions if you feel inclined. Thank you.
