My Hero world

Dr. Ujiko laboratory

The scient super villain was busy looking over his new Nomu experiences. Ever since he got the idea of this monster it had been a huge success for his master. The first Nomu made All Might use full strength, so the concept of more and more coming out…it could destroy the hero society once and for all. But for Ujiko he actually had grown to like those little abominations. In all his life he tries many experiments, but those ones he seen to love. He even called them ´´kids´´.

''Oh, here you go my children.'' Said the evil scient depositing a horrible mix that was considered food to a group of grotesque creatures that was once human.

''AAAAK'' Scream the monster eating that thing like it was their only option.

One little nomu tries to eat the other in some sort of cannibalism matter and Ujiko electrocutes with his remote control until it blacks out.

''Bad boy. Daddy doesn't like this way.' Said him with some paternal voice.

Soon a voice on his monitor appeared and it was of his master All For One.

''Doctor Ujiko.'' Said the menacing supervillain.

''Yes master.'' Said the doctor

''How are the Nomus coming?'' Asked the supervillain referring to his future army

''Still a working progress. Remember the big Nomu was the best one we got so far. All the others will need a little time to develop…' Said Ujiko going all technical on that question. But All For One wanted the answers now.

''How long do you think they will need to achieve their most powerful form?' Asked him

''Three weeks.'' Said Ujiko being quick.

All For One being a man of patience accepted that.

''Ok. In the meantime, Tomura will continue to look for new members.'' Said him.

''Alright.'' Said Ujiko.

But before he could go All For One made some more questions

''Oh, how is your side project doing?' Asked him now interested

''The world teleporter?' Asked Ujiko also with a smile

''Yes.'' Said All For One with a very curious tone.

This has been a dream project from the two for almost half a century. The idea for them to go to other worlds and gather allies to destroy the Hero society. Ujiko has been developing the teleporter for years and years and most of the time it ends up with the test subject dead. But now with technology more advance, he could actually succeed.

''Still a working in progress but I think I can make it work this time.'' Said the Doctor.

''How long can you go to another word?" Asked the Supervillain

''So far in my calculations 2 minutes.'' Said Ujiko.

''Not much.'' Said All For One displeased.

''Yes, but if I get these parts I can make the time limit go to almost an hour.'' Said Ujiko showing the last material necessary to make the teleporter work. With All For One underground information, this would be easy

''You got yourself a deal.'' Said All for One with a smile. Ujiko never disappointed him.

''Thank you, master.'' Said the doctor with a joy tone.

''no thank you Ujiko. Without you I didn't know where I would be.'' Said the sinister voice

''Yes.'' Said Ujiko with tears of joy

A week later

Ujiko had spent the last week doing only experiments with the teleporter. Using Nomus and other things as test subjects and most of them end up exploding or worst, but the doctor after finishing some upgrades theorizes that he is near his achievement.

''Ujiko.'' Said the cold voice of All For One

''Yes master.'' Said Ujiko

''How is the teleporter doing?' Asked him

''Is working proper and maybe we could visit another world.'' Said Ujiko super excited.

''How do you know if it will work?' Asked the villain in wonder

''We'll let's try with this apple. Is gonna be a better test subject that monkey.'' Said Ujoko putting the fruit inside of the teleporter.

''What happens to the monkey?'' Asked All For One

''Let's just say it was a mess around here.'' Said Ujiko with a smile

''Alright.'' Said All For One with a sweat over his head

Ujiiko then using a non-moving object such as an apple was a whole new thing. Because since it didn't move it could go without their molecules being torn apart. Ujiko had a black screen sensing where the apple was going and after a few minutes of a show of lights, the apple disappears. Then looking at the monitor Ujiko saw that the fruit end up in a different world, didn't survive as much but at least he made progress. It was a success.

''It worked. It worked.'' Said Ujiko all excited that this experiment worked

''Doctor. Congratulations.'' Said All For One all happy. His longtime plan was finally going to the right track.

''Now it is time to see if a living organism can go to this portal.'' Said All For One

''Well, I can make some adjustments and send some Nomus.'' Said the Doctor

''Alright, you have my permission. See you later.'' Said All For One finishing his call.

One week later

Today was the day that All For One and Dr. Ujiko broke the barriers of their world. They will be the first people to send actual living beings (a Nomus) into another world. The apple didn't last that long, but these monsters could do the job.

Ujiko put two very larges Nomus inside the teleportation pod, they were already trying to kill each other so he gotta be fast this time

''So, doctor. Do you like to do the honors?" Asked All For One but this time showing his face to see this miracle.

''I have been waiting all my life for moments like this.'' Said the Doctor already in tears.

After that, he pushed a button and the teleportation happen, the Nomu cry in pain but it was for a great cause. Their skin was burning but it didn't matter because after a big flash of light the monster disappear. Ujiko and All For One were astounded that this planed actually worked. The exploration of other worlds.

''It worked. It worked.'' Scream the doctor in pure joy.

''Congratulations my good friend. If I was there, we would be drinking champagne to celebrate your success.'' Said All For One

''Thank you, master.'' Said Ujiko still crying

''So is he already in a different world or they are in limbo?" Asked the villain

''He is in Limbo. I haven't chosen the world yet because I wanted you master to pick our first exploration world.'' Said Ujiko

''What honor.'' Said All For one with a chuckle

''I spent countless nights getting crappy shots of others world that I think you might like.'' Said Ujiko

''Bring me the images.'' Said him

''Of course.'' Said Ujiko

Ujiko then shows All For One countless images of different worlds. There was one with an appearance more of a fantasy seating, one with a large ocean, one that resembles more feudal Japan, one full of people flying brooms and so many others

''Well some of them are pretty interesting. But I need to pick something easy at first to find a subject.'' Thought All For One

''Uh…this.'' Said All For One pointing to a picture that shows an island in the shape of a whale.

Ujiko looked confused at his master choice. That was apparently one of the most peaceful choices of the whole collection.

''This one master? But why is so peaceful?'' Asked Ujiko

''Yes, the peaceful place are gonna be a good way to explore a new world and in case I got surround by heroes and All Might I know where I go.'' Said the master villain.

''Excellent sir. I will prepare the other Nomus to go.'' Said Ujiko hearing his master

''Did you already send the Nomu to this location?'' Asked All For One

''Yes, but by the time I get the others he is gonna become a pile of flesh pretty soon.'' Said Ujiko going to his horror laboratory

''Excellent.'' Said All For One with a chuckle.

A few moments later

Ujiko then put two giant Nomus on the teleporter. They were very anxious, and they look were too kill each other. But the doctor put some command chips inside of their brains, so they can go and do their mission. Bring back one specimen of that world before the time runs out. And it has to be a human

''Alright are you two ready?" Asked Ujiko to the monsters

''Roooar

''Good. Now let's get set.'' Said him preparing the machine with made the monster more agitated.

''Roooar

''Go there and make daddy proud.'' Said Ujiko seeing his monster to the other world where he hopes to find something that can benefit his master.

Buzz

''I just hope you bring something of use to us.'' Said Ujiko seeing his timer of how long the teleporter is gonna work.

Whale Island

It's been 2 whole years since Gon (now 15) had gone back to his home and retire of being a hunter. After all, he found Ging so he decides to spent time with his family. His aunt and grandma were making lunch while he was ready to set out.

''Aunt mito I´m going fishing ok.'' Said him ready to go.

''Wait Gon. Did you finish your homework?'' Asked Mito

''Yes, aunt mito.'' Said Gon impatient. Ever since he got back is been just homework and essays. It wasn't fun but hey he needs to finish.

''Good, you are getting the hand of it.'' Said Mito all proud.

''Sure bye.'' Said him picking his fishing rod.

''Now come back before lunch.'' Said Mito with a smile

''don't worry.'' Said Gon going out.

Mito saw her nephew going out to the forest. He was already 15 and was starting to become man, but unlike Ging he promises to never leave his home.

''Can you believe it's been two years since he came back and he doesn't want to return in being a hunter.'' Said the grandma. And it was true since Gon came back a lot of his friend went to check on him and offer him to go on adventures, but he declines.

''Yes, this is so good. I don't have to live in concern for his life anymore. I remember Gign doing those crazy things when we were kids and I thought he was gonna be like that.'' Said Mito

''He is not Ging.'' Said the grandmother

''And I am so happy for that.'' Said Mito

''Me too.'' Said the older woman.

Gon was in his favorite spot for fishing. Near a hill that leads to the ocean. It looked horrified but Gon loved that place, it had the best fish in the whole island.

''Oh, man today sound like an amazing day to fish.'' Said him all happy for his surround

Soon the animals went near him. They love the teen because of how friendly he got with them, he sometimes rescues them and saves them from hunters. Ironically since he is a hunter himself.

''Hey, there guys.'' Said him seeing magical beasts, deer's, bears, and other animals near him. They even wanted to eat his bait.

''Don't eat that.'' Said Gon saving his bait for the fish

Soon the animals went from joyful to dawn right scared as they sent danger near.

''What is wrong guys?" Asked Gon and soon he saw two large monsters that he never seen in his entire life

''Rooar''

It was the Nomus and they went charging from the forest already killing many animals and ready to make havoc until their time was gone in this world

''What that...'' Asked Gon in pure shock putting his fishing rod in the ground and then overseeing the monsters with Gyo.

Gon nen was coming back after his fight with pitou. It wasn't at the same level during the palace invasion, it was the same when Bisky trained him. But he wasn't at full strength again.

''Are those Chimera ants?'' Thought him remembering that there were a few ants that escape the NGL. However, he didn't saw any human nature on the,

''No, they don't look like if they were human.'' Said Gon now tense. If these weren't the ants, then what they were.

Gon went charge with Ren and try to deliver a punch to the new monster. While it was strong apparently did nothing, shocking Gon

''My nen is still on the works. I can't go full.'' Said him trying to make sure that the monster didn't go near Mito or his grandmother

Gon try to deliver another attack but the second Nomu grabbed him by the leg.

''Arght'' Said Gon

''Roooar.'' Scream the monster tossing the teen into the ground

''Wait…'' Said Gon tries to argue but it was too late

The nomus then start to pummel Gon into a mess. Even after all the exhaustive training that he had been doing Gon was not in the same shape he was during the invasion. Besides, he hasn't fought in a long time. Gon was now beaten and unconscious

''Rooaor'' Scream the monster in victory

Soon a hologram of Dr. Ujiko appeared right in front of them. With a countdown soon to be reaching zero.

''Did you find any specimen?' Asked Ujiko

''Rooar.' Scream the Nomu pointing at Gon

''Good I can teleport you back with some time left. Good job, daddy is happy.'' Said Ujiko preparing the machines to send his monster back to their world

Buzz

The Nomus disappeared leaving a field of burned grass and destroyed trees. It was like if a hurricane had passed by. And with them Gon was gone from Whale Island

At Mito house

The orange-haired woman was preparing a meal when suddenly she saw her grandmother looking outside very confused

''Grandma what is wrong?"

''The animals. They are more agitated than before. Something must get them very agitated.'' Said the older woman

''What do you mean?" Asked Mito

The two women then put the two pieces together and soon realize that they were there to deliver a message. A message about it…

''GON!" Scream the two very scared for the safety of the teen.

They all run to the point where Gon usually fish. It was far and on top of a hill, only he to pick a place like that.

''Where he goes to fish?" Asked the old woman

''Over there!'' Scream Mito

They run to the place and found his fishing rod destroyed and some blood in the ground.

''Oh no.'' Scream Mito fearing the worst.

''What happened here?" Asked the grandma looking at all the animals around who were still very shaken by the Nomu attack.

''Gon! Gon! Where are you?" Scream Mito in desperation, even as far to go down on the hill.

''Mito stop!' Scream the grandma grabbing her.

''He is down there. Could he….'' Said Mito forming tears in her eyes.

''No. He is not dead. He is Ging son for heaven's sake.'' Said the grandmother comforting Mito

''No. He finally got back to us and he almost died before. I can't afford to lose him.'' Said Mito bawling out tears.

''We are not losing him. He is somewhere here. He just needs to find him.'' Said the grandmother comforting Mito.

''Gon please. Where are you?'' Asked the older Woman looking upon the seas near whale island.

Difference places of The Hunter World

Hunter Association

The Zodiacs were having a meeting about the Hunter Exam that was about to happen in a few months. The discussion was to pin down what were the best courses to take this year. Then suddenly the new members Kurapika (Rat) and Leorio (Boar) jumped out of their seats scaring the other members.

''Huh'' Said both of the rookie hunters confused.

''What's going on?'' Thought Kurapika confused. He felt like something was missing, something important.

Leorio also felt the same.

''Leorio, Kurapika. Are you two ok?" Asked Cheadle in concern

''Hey Boar, Rat. What is going on?" Shout out Kanzai

The two hunters then suddenly said a name that left everyone in the room confused.

''Gon.'' Said both Kurapika and Leorio.

Killua and Alluka

The brother and sister were now traveling on a train in destination to the Kakin empire. In the short of two years, Killua mastered his Nen but also help Alluka control Nanika way better. Now while in the train, Killua felt a weird sensation like he received a big shock

''Huh.'' Said Killua all weird out

''Big brother what's wrong?" Asked Alluka concerned for her big brother

''Gon'' Said Killua out of nowhere thinking of his best friend

Monel and Knov building

The two others hunters who were members of the extermination team were now living a pleasant life. They still act as hunters, but they were taking less dangerous jobs. Right now, their apprentice's Knuckles, Shoot, and Palm were training Ikalgo and Meleoron for the Hunter exam.

''Come on Ikalgo. After this, you are going to do 50 more pushups.'' Scream Knuckles to the octopus who was doing sit-ups.

''Why is this necessary?" Asked Ikalgo in pure exhaustion

''You wanna be a Hunter?'' Asked Knuckles all pissed

''Yeah'' Said him feeling embarrassed

''Then you have to surpass everything that you know. Now come on! For that more sit-ups. '' Scream Knuckles

''Crap'' Thought Ikalgo in pain.

''How is Meleoron doing?' Asked Knuckles to shoot with a chronometer. At first, he didn't see the chameleon man but then

''Ha.'' Scream Meleoron gasping for air

''5 minutes not bad.'' Said Shoot

''Right. But he needs more time when in pressure.'' Said Knuckles analyzing the chimera ant time.

Nearby Morel and Knov observe everything with chuckles and joy

''Man. And I thought I would only have these two and now we have more to come.'' Said Morel with a chuckle

''Agreed. We never expect what life gives to us.'' Said Knov.

Soon Palm enters in the room.

''Master I am making tea. Would you guys like too?' Asked her

''I accept.'' Said Knov alongside the rest of the boys excluding Morel

''Thanks, girl but I am good with my drink.'' Said Morel holding a beer bottle

''Alright.'' Said her going to the kitchen

''Hey Palm, do you need any help?" Asked Ikalgo

''No, I am fine.'' Said her picking a tray of tea.

''Here….'' Said her but suddenly she starts to scream very intense

''AAAAAAH.'' Scream her scaring everyone

''Palm what's wrong?" Asked Knov

''Is gon. I can't see him with my Nen.'' Said Palm in pure shock. Sometimes she likes to check on how Gon is doing in his new life but this time she only sees on her multiple vision a black void.

''What! Impossible.'' Said Morel

''Are you sure?' Asked Knov looking at his apprentice

''I am pretty sure. There is no other reason.'' Said her shaking.

''So, what does that mean?" Asked Shoot

''It means he is not in this world anymore. I could watch him even if he was in the dark continent.'' Said her in shock

''What!' Scream most of the guys and then Morel cellphone starts to ring.

Buzz Buzz

''Is Leorio. I guess he also felt that.'' Said Morel answering the Zodiac.

''But how is this possible?" Asked Ikalgo to the other hunters who all had a concerned face for their friend.

Other places

Many others of Gon Freecss friends and colleagues all felt some weird feeling in their body and then suddenly they thought about him. It was Mr. Wing and Zushi, Bisky, Hanzo, Kite, Goreinu, Melody and surprisingly Hisoka and Ging all felt the same way, and all have only one thought in mind. What was that?

My Hero world

Dr. Ujiko was seeing the Nomus materialized back into their normal selves. He told them to hold the specimen in a position that couldn't alter once back into his world. He needs the specimen in perfect condition.

The scient wait for all the molecules of the three subjects compose in his machine so he can start making researches. Soon the Nomus come back in a big explosion that shakes the entire laboratory

BOOM

The explosion shook everything, but the machine was fine and the Nomus had returned to their creator. The only problem is that the travel was still not fully perfect so both of the Nomus had their skin appearing and starting to burn off. The two still protected Gon so he wouldn't get destroyed during the trip.

''success and this time only a few parts of your skin are missing.'' Said Ujiko smiling

One of the nomu then starts to melt like if he was made of some kind of weak material. Soon there was nothing but a disgusting

''He still on progress.'' Said Ujiko unpleased to see one of his creations dying like that. At least one was alive and holding Gon

''Oh well let me what you two brought.'' Said Ujiko

Ujiko then saw the green-haired teen in such a peculiar way. He checks his body and saw that he had muscles and a very weird spiky hair.

''What a weird brat.'' Said Ujiko looking closely at the unconscious Hunter.

''But he is strong I can sense that. Bring him to my lab.'' Said him to his Nomu who only obey its master

Ujiko laboratory

The doctor was now with Gon on a weird metallic table as he made researches on him. He wanted to see what he got in power before he dissects him and checks all the organs that he has inside.

''Well let's see who you really are.'' Said Ujiko inserting some of Gon blood into one of his machines that start analyzing his status.

Analyzing being

Gon Freecss. Specie Human. Quirk none. Superpower none. Level treat A-level.

''Interesting. You don't have a quirk but is strong enough to be an A-level treat. I think Tomura is gonna will like you.'' Said Ujiko ready to do an experiment in Gon and maybe if he survive to turn him into a Nomu

''Now let's start this.'' Said Ujiko grabbing a knife ready to cut Gon when he notices something sticking out of his hair.

''Uh''

''What is that.'' Said Ujiko grabbing some white hair stuck on Gon. It couldn't been his because there were no others like that.

''White hair?'' Said him confused

''Let's see who is from.'' Said Ujiko putting the hair in his machine that starts analyzing.

Analyzing

Neferpitou. Specie Unknown. Quirk none. Level treat S-level

''unknown species and level treat S!' Scream the doctor in shock. Just what in the world was this Neferpiotu

Ujiko then had a brilliant an idea. If this thing was unknown and was a total monster, he sure as hell is gonna know what it is.

''Let me take you my good friend to a better place.'' Said him picking Neferpitou hair and putting him his pocket

Ujiko Nomu laboratory

The place was like hell. Full of weird monster, screaming, and other nightmare visions. Ujiko had started the Nomu project there and so far, every time that he made one it turns out great against the heroes. Right now, he was looking for a little texture

''Let me see here.'' Said him finding a perfect little Nomu body that lost its brain.''

''Oh, you will be perfect.'' Said Ujiko putting the hair into a syringe and injecting into this Nomu dead body. Soon he put the monster inside of a pod and then start to run the machine.

Ujiko plan was simple. Inserting this thing into the Nomu body it will soon grow back into what the original user was. He didn't know of what thing this Neferpitou was but in a few days, he will find out. The most important thing was that this Neferpitou was about to be reborn

''Here you go. Now let see how much of terror you can be.'' Said Ujiko with a laugh starting his machine who start to run.

Ujiko exits the lab not knowing about the monster he is about to awake.

Reproduction pod activated- 00.01% (Neferpitou)

Yeah so in this fic Gon is capture to the My Hero world and in this continuity, a little white hair of Pitou got stuck on him after all these years. I know seen hard to believe but hey my story. The point I wanna do in this story is that I want the heroes and especially U.A to deal with monsters they never seen before. Creatures that for them look like humans with quirks but for Gon, they are nothing but disgusting bugs. Tune next time.
