*Walking over to the computer and sitting down on the chair.*

"Okay, I guess I can try an attempted at a My Hero Academia story. Let's see what kind of stories of that series is on this site fir-."

*Ninety percent of stores are yaio crap*

*Cue sad music*

"I didn't freaking expect this crap," *Gets ups and walks away* "No, f**k it, no I'm out-"

Hey buddies, it is me once more, staring another story despite the fact that I just started another story and that I have like ten other stories to worry about and the fact they most likely will last for years to come when I get older and life gets more in the way and I still planning on publishing the rewrite for another story soon that I've done which will consume my entire being and I rot away in the darkness all alone with no family or children of my own due to writing these stories.

Isn't life great?

Anyway, here I am attempted a My Hero Academia story, cause why not. Let it be known that I'm not too great on Japanese locations as well as the names or how someone's quirks may work in this series just yet, so sorry if I screw something up, I apologize. I will do my best to make it not suck though.

Anyway, so this is basically going to be a My Hero Academia version of my Fairy Tail story "The Children of the Future", because I'm unoriginal. Also I will be using a theory that is most likely not true, but I'm going to go with it anyway cause after all, this is all for fun. Will also contain crossover elements, but if you know me by now, you all would have expected this.

Summary: An unknown organization from the future comes to the past in order to acquire certain individuals. If they succeed, they will gain new instruments of chaos for their unknown masters. However, allies follow them into the past in order to stop them. Who are these you may ask? Why the future children of Midoriya of course! This will be a Deku x Harem, cause this is for fun after all. Takes place after the Overhaul Arc.

Enjoy, or not, I don't care you all have your opinions.

Chapter One: Arrival

Over the ocean not far from the nation of Japan, everything was as calm as one would expect. With no boats around, with the birds just flying over the sea to find fish close to the water's surface to eat, and with the sun out and bright, everything was as peaceful as it can get.

However, the peace would soon end as all of a sudden, a massive purple like energy ball appeared over the ocean, getting the waters to be disturbed as well as scaring off the birds that were near it. The ball of energy continued to lash out, getting bigger and bigger…

…Until another flash of light erupted from it. And then, as the brightness faded, instead of the ball of energy, it was now a floating citadel. Being as large as an island, the dark and terrifying citadel towered into the sky, as massive walls were seen on the edges of the floating rock the place rested upon. If anyone were close to the flying citadel, they would surely no doubt feel the rather dark and vile energies that linger all over the place. The walls themselves had defensive on them, ranging from cannons, and other long ranged arterially noticeable on the wall.

Somewhere inside the massive base of operations, a dark room was seen with no one but three individuals all in a circle inside of the dark chamber. The three currently could not be seen clearly due to the darkness, but their eyes, or the light from the helms they were, could be seen.

"It worked. We have arrived in the right time period." One of the three spoke to the others, his voice showing his calm side.

"I do not sense the intruders' presence. It's clear that they must have ended up elsewhere on this world. No doubt they all ended up somewhere nearby though." A second voice, this one sounding more serious compared to the first.

"It matters not, by the Old Ones will; we will achieve our goal, no matter the cost." The third one, which sounded calmer like the first, was heard to speak.

They have achieved the first part of their plan. Now the time has come to collect their objectives. And no one will stand in their way.

No one.

'LATER, ELSEWHERE ON JAPAN'

It was a dark night in the city of Musutafu. Many people were already at home sleeping peacefully, while many others were still up, either they were shopping, going somewhere, or just have fun at their locations.

In a dark alleyway though, nothing fun was going on as a group of thugs were ganging up on a woman who looked to be in her twenties. Her mouth was gagged up by one of the criminals, as the other villains all had lustful looks in their eyes.

"Today seems to be our lucky boys!" One of them, who looked more like a humanoid armadillo than human, told the others, who also looked more like animals, showing that their quirks were animal based.

Sadly for the woman, she didn't have any quirk that could aid her in getting away from these thugs, as tears were streaming down on her face. This merely got the other thugs to laugh.

"Oh, man the things I'm going to do to her." Another thug that looked more badger than human spoke, as he and the armadillo one got ready to have their…fun… with the woman.

Before they could start anything though, something suddenly shot out of the dark shadows deeper in the alleyway, grabbing two of the thugs, who looked down to see a red liquid substance wrapped around their legs.

"What the-?!" One of them started to exclaim, before the two were pulled right into the shadows while screaming out.

This naturally got the other criminals to look on in shock as two of their members were dragged into the dark alleyway.

"What was that?!" A thug that looked like a humanoid horse questioned, as the screams of their two allies ceased.

This naturally got them all to be a bit fearful.

"What's going on guys?" The badger-like guy asked the other two, as the kidnapped woman only looked at the dark alleyway in shock by what just happened.

Since they were all too busy looking at the deeper and d part of the alleyway, they didn't noticed the black portal-like warp gate that opened up behind them. And before they knew it…

"SURPRISE!" A crazed yell from a male got them all immediately to turn around.

Before the horse-like guy could say anything, the new guy shoved what looked like a knife right into the thug's skull, killing the man instantly as the body fell lifeless to the ground with a thud.

The remaining two thugs and the captured woman looked on in shocked before they looked back at the sudden appearance of the male.

The new guy only looked to be around sixteen years old. He had messy blonde hair with a bang going over his right eye. He was shirtless, as multiple scars could be seen on his arms, and he wore grey colored gym shorts that went pass his knees, though they had blood splatter on them. He was also not wearing any shoes, thus leaving his feet bare. Around his waist though was a belt that seemed to be holding multiple knives. Then there was his face. His eye color was yellow, but the most thing that is creeping the thugs and captive lady out, was his crazed grin that was plastered on his face.

"W-Who the heck are you creep?!" The armadillo-like guy shouted at the guy, getting ready to beat up this creep who was messing with them.

The blonde haired male simply chuckled in a rather creepy way, before his eyes widen with excitement.

"I'm the Boogie Man!"

That was all he said before he dashed at the thugs, which were then followed by screams echoing out of the alleyway.

'NEXT DAY'

It was normal day for the students of U.A. High. Class 1-A were getting up to go onward for school. Many of them were already in the main living area, either eating breakfast or watching the T.V. real quick before they all head out. As one would expect from this group of students, they were all in groups talking with one another, watching the T.V. with one another, finishing up breakfast, or were just returning from a quick run, which was what Izuku Midoriya and Tenya Iida just did. Only Bakugo wasn't present as he already ate and headed to class, not wanting to deal with their usual antics, since it got in his nerves.

One group, who consisted of Ashido, Sero, Kaminari, and Kirishima, were hanging with one another as they finished breakfast while seeing what was on the T.V before they all headed out to class. However, something popped up on the news that got the four students to be a bit interested.

"Huh, guys take a look at this!" Sero called out to the others in the kitchen and living area, getting all of their attention as they made their way to where the Tape-Quirk User was at.

Looking at the T.V., they saw the news reporting on what got the other four students' attention.

"Around sometime during the night, reports have been coming in on a string of murders that have caught people's attention," A woman reporter was telling the audience as a screen showing multiple locations with cops and Pro-Heroes investigating the scenes, "We managed to identify the bodies, with them all having some kind of criminal background. We don't know who was responsible, as witnesses were unable to get a good look at the culprits. We'll bring in more news once more information is released"

"A string of murders?" Ojiro questioned, as he and everyone else were curious by what they were just told.

"Yeah… that doesn't sound good." Kaminari spoke up back at the others.

"But they were all villains, so it's not like the murders were innocent people." Hagakure put in her thought on this, as she was trying to find the positives by what they saw on the news.

"But this obviously wasn't done by the hands of a Pro-Hero, so that raises the question on who did it." Asui put in her own two cents on the matter.

"Maybe it was done by a vigilante?" Mina guessed. While it was true that vigilantes were forbidden nowadays, that hasn't stopped some people from going down that path.

Momo looked at the time, and seeing that they should get going if they were all going to get to class on time, the black haired girl stood up from her spot on one of the couches, getting everyone else to look at the top student.

"We'll discuss this later, we need to get to class or we'll be late." She informed them as she went to grab her things.

"She's right!" Iida exclaimed like he usually does while making his hand gestures, "We must not tarnish our arrival times! So let's get going everyone!"

Izuku and Ochaco couldn't help but sweat drop at seeing their friend's usual self. Though that was what made the Engine-Quirk User himself.

"Yeah, let's go." Izuku told the brown haired woman next to him, who nodded with a smile on her face.

It didn't take long for the class to finish up their breakfast or getting their things after that, and with that all done; they were all heading off to the main school building and to their class. Today should end up like any normal day for them.

But unknown to them, they would be wrong.

Tada! Chapter is done. So what did you all think? Good? Bad? Let me know.

Also, I need help with coming up with the names for the future children, so if you guys could provide some names, that would be a huge help.
