Chapter 3:

Nomu warehouse:

The warehouse was a big room, more like a hangar, filled with green tubes. Those tubes, that had the size of a big closet, contained humanoid creatures. In a corner of the warehouse there was a door that lead to the room Sensei was currently in. It was a big room, but it was mostly occupied by a gigantic computer, that glowed as well in green. There were as well some cabinets, and an office with a small computer that was connected to the big one

All for One was reading the file on that computer. ' A power that could reset a timeline', he read to himself. Indeed, this power, BITES THE DUST, as it was called, belonged to a serial killer. Right before his death, many generations ago, he confessed his murders, and that the only reason he hadn't been catched was because of BITES THE DUST. This power was able to rewind time every time someone learned about the killer's identity, and so he was never catched. The only reason he confessed all of that was to see the face of the inspector once he learned the truth, something understandable for someone that had been pulling everything on the shadows, keeping a secret: There wasn't anything better that seeing someone learn a terrible truth. However, the most terrifying thing was one the corpse was analysed: He was quirkless. However, this "quirk" gene was replaced by another completely different. An extensive research was made, but it only concluded that this "gene" was a completely random mutation.

When All for One first received this inform, he didn't give any importance. He thought it was just a madman, that happened to have a mutation in his genome. You'll have to forgive Sensei, after all he was just 90 years old, he didn't have much experience by then.

However, now seeing how young Midoriya possessed a similar power in terms of "impossibility", to say it in some way, and that his quirk couldn't retrieve the power, he knew: it was the same kind of power as BITES THE DUST.

After two whole hours of research on this power and how the brain of the killer worked, he had already concluded some things: First, it acted exactly as a quirk, in terms that it was the same part of the brain that controlled it. Second, it would be impossible for him to take the power. With all of that in mind, he took some documents and warped to the bar. If he couldn't take young Midoriya quirk, then he would just make him a puppet.

At the bar:

Izuku descended the stairs with Tomura. After 2 whole hours of lying in bed, they both had felt asleep. When Izuku woke up, the first thing he saw was a lot of dust where the pillow previously was. 'I got to do something about that', he thought, 'he probably just did it while he was asleep'. After that, he woke Tomura, and decided to go downstairs, see if Kurogiri could make them something to eat. It was already about 2 P.M, and they were both starving. Thanks god Izuku told his mom he would be staying for the day, if not Inko would be dead worry by now. So they went downstairs and asked Kurogiri for something to eat

-"Well, we have some curry from yesterday", he said to the two kids. Then, he addressed Midoriya "Do you like curry? Do you have some form of allergy? Maybe to gluten? You don't have to worry though, it doesn't have any."

-"N-no sir, it's fine", said Izuku, sweatdroping. He couldn't understand yet how such an elegant and powerful man was so… caring? To say the least. It was as if Beast Jeanist was constantly asking if he had his coat, so he didn't catch a cold. The thought made him giggle a little, something both Tomura and Kurogiri noticed, but didn't mind.

Just before they finished eating, Sensei appeared, carrying a suitcase.

-"Kids", he said as he sat on a chair next to the counter, looking at both kids," I have found some things that will help young Midoriya access to his quirk. When you're finished eating, I will warp us to a laboratory I have. There", he said, now looking at Izuku," we will determine how your power works."

-"Thank you very much, sir" said Izuku, lowering his head in respect. He started to feel the same way about the man as Tomura did. He wasn't rescued by him, but there was something about the intimidating figure that, paradoxically, reconforted him. It was somewhat similar to what he always felt whenever he saw Allmight on a video: the feeling that nothing wrong could happen to him.

-"Oh, please", said the man, standing up," call me Sensei".

Meanwhile, at the park:

Bakugou was playing "heroes and villains" with some friends. He was the hero, obviously. That damn Deku hadn't come today. The coward usually never came after he beat him. However that was only a day or two, after that he would just follow them as usual. However, it had been a whole week now. He didn't know what to feel. In one side, he was relieved not having the annoying green kid following him around, cheering everything he did, it was as if he was mocking him. However at the same time he felt… worried? Worried that he wouldn't come back? In school he had been absently staring at the walls or his hands. No. Not absently. More like he was extremely focused on something. Anyways, the fact that he didn't came all this days made him feel sorry?

-"Oi, Katsuki!", said a kid" You're playing or what?"

-"Yeah, yeah, shut up idiot", answered aggressively the ash haired kid.

No, It was impossible for him to be sorry. That would mean that he did something wrong, and that was impossible. It was all Deku's fault for being a liar like he was. Deku was a nobody, and he would be the number one hero."

At the lab:

All for One just warped with the two kids, leaving Kurogiri at the bar doing his things. The lab was a big white room. It was filled with machines of every kind, and in the middle of everything, there was another little room, with walls made of thicc(k) glass.

-"Now," said All for One, as he entered the glass room," shall we enter the room."Izuku started to look at him with a little concern."Worry not, young Midoriya", said the man, actually reading the kid's thoughts thanks to a quirk of his," it's not a cage, it's only so we can have clean lectures on your power."

With that, the little kid a little calmer, entered the room with Sensei and his friend. The last had insisted in coming, saying that he needed to see his friend's power.

-"Then," explained Sensei,"I will use a quirk of mine on you. It's called Impel(yes, it's a reference to Skykadet13's fanfic, go check it out if you haven't, the character of Izuku is brilliant). With this quirk, I will force your power. It theoretically only works on quirks, but according to my research, it will also affect to the part of your brain that controls the power. I have to warn you, it will trigger your power to its maximum extent for now, so you'll feel really tired, as if you had used all your strength, because you will. Are you ready?", asked All for One, to what Izuku shook his head in approval."Very well."

And with that, black tendrils shoot out of the man's fingers, connecting with Izuku's chest. And after feeling the black traits touch him, he felt how time stopped.

Now that he payed attention to the feeling, it was as if he was trying to stop a wheel, feeling how it had force propelling it towards, but stopping it nevertheless, as if he was a break. The world had turned grey, and he couldn't hear anything, just like last time. It was as if he was in a completely different world, only he could access. One second passed. Two seconds passed. Up to five seconds passed in his world, but then, he started to feel nauseous, as if he had runned too fast for too much time. And so, time continued his course anew. When he returned to the present, he fell to his knees, gasping.

-"So?", asked an impatient Tomura, "How is it?"

-"Let him take some air, Tomura", said Sensei calmly, and after a few seconds he asked,"More importantly, do you feel how it is to access your power?"

-"Yes, I think i know how to do it", said Midoriya, as he accessed his quirk again, this time for only 2 seconds.

-"Excellent,", said the man, pleased," now I want you to try and move in stopped time."

-"A-allright…", and with that, Izuku entered his world of stopped time and took two steps to the right. After he let time flow, Tomura looked at him surprised. Outside of his world, it was as if Izuku just blinked from one place to another, and the blue haired kid thought at the beginning it had just been his sight that had failed him. However, the tall man knew perfectly that it was work of Midoriya's power.

-"Lastly, I want you to try and stop and let flow time repeatedly as fast as you can"
Izuku stopped time again. Each time it was easier, starting to do it almost without thinking. He stopped it for 4 seconds, not wanting to puke, and let it flow. However, he wasn't able de stop it again for another 4 seconds. It was as if the wheel went at the same speed, but the brakes just scraped it, not stopping it. He then tried stopping time for only two seconds. And when he started it, he wasn't able to stop it for another 2 seconds. 'As thought, it doesn't let me stop time for as long as I have already stopped it.'

-"So?" Asked All for One patiently

-"I think I can only stop it after a cooldown", explained Izuku," that is the same amount of time as I have stopped time before".

"Huh", chuckled Tomura," Equivalent exchange, I guess."

-"You have done very well, young one." said All for One, as he kneeled to the level of the kid and put a hand on his head,"For now, rest. I will analyse the readings on your power. Train it, and break your limits.", he then stood up, looking at Shigaraki"Tomura, you have made yourself a good way. Don't let it go."

And with that, he warped the two kids back to the bar.

In front of Izuku's house:

After training with Sensei, Izuku just felt exhausted. Stopping time so much time repeatedly felt like he had all the energy of his body. So Tomura, seeing how his friend was going to black out at any moment due to the fatigue, asked Kurogiri to warp them both to Izuku's house. After ringing the bell, the adult and the two kids were welcomed by Momma Midoriya, who almost forced them to enter and have dinner. However, while the two kids were setting the table, Kurogiri received a message from his master: 'Nomu warehouse, now.'. He wasn't used to All for One speaking to him in such an imperative way, so after almost five whole minutes of apologies, he excused himself out of the Midoriya's household, leaving his phone number so that he knew when he had to come over take Tomura..

The two kids were finally on the table, eating katsudon. Inko couldn't help but smile, it had been almost a year since his friend's quirks started to appear, and in that time, his son had stopped inviting kids over, and being as joyful. That's why seeing him laugh with the kid (who oh god, needed some hydratation on his skin), made her heart a little warmer.

-"Shigaraki", said the mom, "I have noticed you eat in a very elegant way. It's a joy seeing such young kids with modals", she exclaimed cheerfully.

Izuku and Tomura couldn't contain his laughter. Just thinking about Tomura as a refined gentleman instead of the rude self he was made them want to fall to the ground.

-"Mom, no," said Izuku, containing his laugh,"it's just his quirk. He turns everything he touches with all five fingers into dust"
-"Oh dear", said the mother as she drew a hind to her mouth," your bed must be such a mess".

The fact that she wasn't actually wrong made the three burst into laughter. It was fine, for all of them, to feel like they did at the moment. For Tomura, the kid who had lost everything and was abandoned by heroes, to feel he had some motherly figure with him. For Izuku, the child that had been bullied for almost a year now because of his quirklessness, to have an actual friend. And for Inko, just seeing his baby boy in such a state of joy, made her want to cry.

After they had finished eating, Izuku went to her mom with Tomura. She was finishing cleaning the dishes, when Izuku pulled her skirt a little to get her attention

-"Mom, with Tomura and Sensei we have discovered what my quirk is !", exclaimed Izuku

-"Oh, really?!", asked Inko, intrigued," and who is that Sensei you talk about?"

-"Oh, he's…."

-"He's my guardian", said Tomura

-"Oh, but I thought that Kurogiri man was your guardian", said Inko, as she placed carefully the last glass she finished cleaning next to the drain.

-"Well, he's also my guardian", explained Tomura," except Sensei is the one that teaches me everything because I don't go to school. Kurogiri is more the one that makes me dinner, makes sure I'm warm at night and helps me with my homework from Sensei"

-"So, he's like your teacher and Kurogiri is like your dad!", exclaimed Izuku, having figured it out

-"I...guess", said Tomura, blushing a little. It was true Kuro acted like an… overprotective parent.

-"Anyways baby, what's your quirk?", asked the adult

-"I can stop time!", said Izuku, keeping his enthusiasm

-"Dear, we had already talked about that,"said Inko, saddening a little," it's just that you see things a little slower, like boxers while in a fight".

-"But mom, look!", exclaimed the young one as he froze time. In four seconds, he moved behind his mom, and took the glass she had previously cleaned. After resuming time, it appeared as he had teleported behind the mother , but had the glass on his hand. Tomura, now used to his ability, didn't reacted, but Inko let a little gasp of amazement.

-"My, then it's possible", said Momma Midoriya, awesomed," I never thought such a power could be possible. Izu, my dear," she said pulling him into a hug" you can, and you will, my boy, become a hero".

Tomura didn't know what to feel at the moment. It was a little bit awkward, just standing there in such an emotive moment for the two Midoriyas. In the other hand, he felt angry at the mention of heroes, as he did always. Seeing a kid just wanting to be a hero, not understanding how rotten society was enraged him. However, he reminded it was Izuku the one we were talking about. He only knew him for a week now, but he felt connected to the kid, and he was so pure, as if even just as a kid, could already considered having the character of a true hero. If anything, he felt happy, happy that he could see his friend and his moms crying of joy.

-"Mom," said the green haired kid," can Tomura sleep over? Please please please please…"

-"Sure, I'll just message Kurogiri to tell him he doesn't have to come over", said the adult," Meanwhile, why don't you two go upstairs play?"

-"Yeah, let's go Tomura!", and with that, the two kids ran upstairs.

Nomu warehouse:

Kurogiri just received a text from Tomura's friend's mom, saying he would be sleeping over. At first, the mist had been scandalised because the kid didn't have any pijamas, or his toothbrush, and he had the tendency to disintegrate the pillows at night, but after several minutes of texting, Inko reassured the man that Shigaraki would be alright.

Kurogiri had been helping All for One for almost an hour now. They were on the Nomu warehouse, in the office, Sensei in front of the computer, and Kurogiri reading some files next to him.

They had been going over the lectures of Midoriya's experiments. At first, it was something nerve cracking: it didn't have sense how his power worked. There had to be some residual effect to stopping time, but there wasn't anything in the lectures, not a small change in gravity, nor a wind provoked by the kid, that theoretically was moving way faster than light. The reason why Sensei asked for Kurogiri's help was that, while he may be a villain and a half time dad, he also had a degree in physics and neurology, and was the main collaborator in the creation of Nomus, and for someone that had genetically engineered a killing machine, this problem was being the hardest one yet.

-"What if,", proposed Kurogiri,"he doesn't move faster than light?"

-"Then there wouldn't be an explanation to why he moves so fast", responded the master," it is impossible to stop time. Time, unlike space, doesn't have a… physical tissue. Black holes are created distorting the tissue of space, but time is just a human invention,"he continued, as he stood up, looking at the same files as Kurogiri."a name for actions that succeed each other."

-"Yes, but it's the only possible option we have left. He doesn't teleport because there isn't residual matter, he doesn't move faster than light because there's not wind, and he doesn't stop time because that's actually impossible"

-"Then what options do we have left", asked Sensei. He was the most powerful man in the underworld, and knew everything about quirks, that's why seeing that a simple power turned into such a headache was… enerving.

-"Wait…"said Kurogiri, realizing something"What if he doesn't stop time. What if he shapes reality itself?"

-"Explain" said All for One, not knowing where this was going. To shape reality was impossible, something that only a god could do. Yet, there had been a man that restarted timelines, so it wasn't really inimaginable

-"Like when you're editing a video", continued Kurogiri" you cut a fragment, and insert a small video inside, what if he can do that?"

That was something terrifying. That meant that a 4 year old kid could actually rewrite reality at will. He did not know how it worked, but this power was extremely similar to the one belonging to the serial killer, who could rewrite reality, just unconsciously. In the reports, he stated that he did not know how many times he had restarted the timeline, that it restarted itself once somebody knew his identity without him doing anything. However, young Izuku could stop time at will, and so rewrite reality.

-"It's only a theory", said the mist,"but it's worth a try, if he actually rewrites reality, there should be some indicators in his brain. Even if it's in time stopped, when it restarts we can have a small clue to how his brain works while using the power. I'll start preparing some tests. Master, you should get some rest."

It was true that All for One hadn't slept in days. While he had some quirks that made his caffeine levels sky rocket, that didn't actually replaced sleep.

-"Thank you Kurogiri" and with that, he warped away, leaving Kurogiri working on his computer.

Izuku had proven himself a terrifying weapon. He needed him on his side. And he was going to have him.

Izuku's room:

Izuku and Tomura were playing poker. For the last hour or so, Shigaraki had tried to teach the game to his friend, and just the simple rules had taken half an hour. After that, they had started playing the game itself. The thing is, Izuku was terrible at bluffing, while Tomura had a lot more of experience, because he liked to play with Kurogiri. And if he could identify the bluff of a man that didn't actually had a face, he could read an almost 5 years old like an open book. The little kid would start to giggle if he bluffed, and he never knew when Tomura did bluff. It was just a plain facial expression, not giving any information. 'So that's why it's a poker face', he thought. It made sense, you give the enemy the least information possible. However Izuku, while very young, started to develop a playstyle himself.

In the last rounds, everytime he had a poor hand, he just bluffed, and started to giggle a little. At first, it was involuntary, but then, after a few rounds, he had learned how to suppress and fake the laugh. But this time, he actually had a royal flush. So he actually faked the laugh. Tomura took the bait and betted 4 of his 20 chips, and exactly the same amount that Izuku had at the moment. So the face of Tomura, when he saw that the green haired kid had fooled him in a way Kurogiri never had, was a poem itself.

-"HA!", said Izuku, with a shiteating grin," now that's how you play poker!"

-"Mere luck, young apprentice", said Shigaraki. He knew perfectly it hadn't been luck. It was actually a very good play, playing in long term. It was something that was in that chinese book Sensei had made him start to read. It was actually scary, how in only an hour, a 4 years old had managed to manipulate him into thinking he was perfectly predictable."Anyways, we should sleep."

-"You only said that because now you're scared", pointed Midoriya

-"No, I'm not", oh boy he was scared. He needed to change subject quickly." Anyways, if we're not going to sleep, what do we do? I know!", he exclaimed," what if we name your quirk?"

-"I thought 'Time Stop' was alright", said the little one

-"Nah, it's just too boring. And if someone reads your file, in the case you continue with your heroe thingie," said Tomura with a little despise in his words," then you would be in a disadvantage"

-"Then what do I name it? It would contain time someway or another.", pointed Izuku

-"Ehh...How is it to be in time stopped?", asked Tomura, looking for inspiration.

-"Well, it's…" started Izuku," like if I was in another different world. Everything is in shades of grey, and there is no sound. If I'm attentive, I can even hear my heartbeat! But there isn't much else to it. It's just like a world only I can access."

-"Then that's it!", exclaimed Tomura, snapping his fingers," We'll call it 'The World'."

-" 'The World'?", asked Izuku

-" Yes. In all capital letters, that way it will be even cooler. THE WORLD"

-"THE WORLD, stop time… I like it"

A/N:

So guys, sorry for making you wait so long, so here you have, nearly 4000 words of story.

First of all, a warning. This week, I'm going to be busy as fuck, I've got like 3 projects for the next week, so it's highly probable this weekend there won't be a new chapter.

I must also like: what do you prefer, a very long chapter every week, or two shorter chapters every wednesdays and sundays?

Now that I have revealed how Izuku's powers works, next chapter it will be how he adapts to life with them. Not exactly a filler, more like a preparation for the chapter after that, where I have thought of some things. I also want to make a sassy/ironic Midoriya when he's a teen, thanks to the influence of Tomura, and I want to build this slowly.

Onto the next topic: What Hero/Villain name should Izuku have?

Thanks for all the support I'm having. I'm really sorry if I can't post as many chapters as other fanfics, but it's just that I come home super late after school and all the activities I have, and It's kinda hard to make up time for writing, even if it's something that relaxes me and I like. So, thanks for your patience, and stay tuned for more! (god I need a new catchphrase."
