Alrain: This is another story when Dual quirk Izuku is over inspired kokob5, but I decided to publish it anyway.

I don't own anything of My hero academia.


I'm getting tired I should return soon damn myself for staying up so late!" Izuku scolded himself he was currently flying in his suit (Iron monger smaller.) Izuku was just an ordinary looking kid but he was still different he had no parents he wasn't abandoned or got his parents killed he was simply lost in other word amnesia. The only thing he could remember was an explosion and a name 'Izuku and Deku' when he woke up he couldn't remember anything then that but was lucky to find an not so old abandoned space station that was so big like it could hold 850 people he made it his home he explored it and there was no one there making him wonder why they abandoned the place since it was in perfect shape.

"So why did I make so many suits again?" he asked himself as he then suddenly remembered when he came across a computer he immediately understood everything he checked the internet and discovered that this world was filled with women with superpowers called quirks he was really confused at the words quirk he searched it and read the whole history of it he wasn't interested in becoming a hero knowing only women have quirks, but he discovered when he was checking a device that was out of energy but then worked when his hands produced a blue light when he discovered that he had a quirk he still didn't have a desire to become a hero not knowing if women would accept this much less the villains.

To hold it short he began training developing ripped off muscles and also practiced with his quirk he could create shockwaves, fly and blast energy beams. When he found a storage room filled with high quality metal that was very expensive he made the suits just for the fun but slowly started to enjoy making them improving each one of them he had currently 420 suits (Iron man suits.) and the metal was not even close to disappearing it looked like it it was barely touched he even upgraded his prototype that he was testing it was a bit bulky but was still flexible and comfortable to move around with. He landed on a building wanting to see the city the suit required a lot of power but he could produce an infinite power making it no problem, the suit had pretty much anything here is a list:

1 Anti vehicle missiles

2 Armor penetrating bullets

3 Flamethrowers (Reach up to 5 meters burns through iron.)

4 Power to lift 15 ton

5 Hidden blades (Made of titanium.)

6 Fly at supersonic speed

7 Concentrated energy beam gauntlets (Makes beams more powerful.)

8 Bulletproof/heatproof/waterproof armor

9 Energy shields (strong enough to deflect rockets.)

10 Armor made of gold titanium alloy reinforced with laminated kevlar (Strong enough to resist high space pressure.)

11 Arm Tasers (300.000 volts.)

12 Instant scanning helmet (With AI named Jarvis.)

13 Explosive flares (Can blow up titanium.)

14 Chestpiece beam

15 Electrical cables

The station where Izuku lived was isolated from the main land the station was build on a nearby island so Izuku was a bit social awkward but who can blame him he was isolated from the people while having no interest in making contact he looked down the building and saw something that made his eyes widen, beneath was the place on fire several buildings were destroyed while weird dressed women were evacuating people he looked where the trouble came from. "Jarvis where is the culprit!"

"Scanning sir, it seems like those men there are terrorizing the city and to warn you sir a 4 year old girl is falling from a building at your left sir."

Izuku's eyes went wide when he saw a girl trying not to let go the edge of a building while under her was a big fire Izuku flew towards her and quickly caught her when she let go.

"AAAHH!" screamed the girl as she fell but then felt something she opened her eyes and saw a flying person catching her "Are you a robot sir?" the girl asked cutely while Izuku chuckled inside his mask.

"No I'm not this is a suit, where are your parents little girl?" she then hugged him with her small arms with her eyes closed.

"Thank you mister robot!"

"No problem where are your parents so I can bring you to them?"

"They ran over there they tried rescuing me but got pulled away by other people." as she pointed at a direction Izuku nodded and flew over there with the girl still in his arms. Izuku maybe lived 4 years alone but he cared about life itself he planned to take care of the villains when he brought the girl to her parents.


"LET ME GO MY DAUGHTER IS STILL THERE!" shouted a woman who was held back by a few people while a hero tried to reason with her but they all suddenly looked at the air seeing a figure fly over to them this warned the other heroes the figure landed and the people got a bit scared they thought it was a robot but the mother saw her daughter in the arms of it.

"LUCILLE!"

"MOMMY!"

The mother quickly ran over to the robot and who tilted the girls and placed it in the arms of the woman who hugged her daughter afraid she would lose her again.

"Thank you for saving my daughter!" she sobbed while hugging her daughter tightly.

"No problem at all, miss."

This shocked all the people when they heard it was a male voice it walked away and flew in the air into the direction of the villains while Izuku cursed himself he showed himself in front of the heroes no doubt they were going to chase him he then saw 4 trucks and quickly blasted them making them stop driving they all stepped out and fired their guns at him Izuku landed and walked closer to them the bullets didn't harm him they just bounced off like BBS.

"Sir there are about 15 men armed with dangerous guns."

"Shoot their weapons out of there hands!" he ordered as 2 clips above his shoulders shot the guns beyond repair he quickly ran forward and punched 2 of the 15 out he quickly turned around and shot with an energy beam another 2 down, he picked one up and threw him through a wall he turned around but stopped when they held a girl as hostage she was gagged and her hands were bound but then quickly used the clips to shot them down he quickly removed the gag the girl was around his age she had ash blond hair that reached her neck it was also a bit wild styled, she had a wild look on her face and wore a black student uniform but she also had quite a rack, he wanted to ask something but got interrupted by a feminine booming voice.

"THERE IS NO NEED TO WORRY, FOR I AM HERE, TEXAS SMASH!"

"Texas smash?" Izuku turned around only to be met with a punch that met his helmet launching him several feet away. "Ouch! Jarvis is the suit okay!?"

"Yes it is okay that blow left nothing but a little dent sir, so no need to worry."

Izuku looked at where he stood once he saw a tall female with gold blond hair that reached to her back she wore a plain white t-shirt that hugged her body along with jeans and black boots while smiling and then turned around to look at him.

"You there don't move, you may have saved this girl but your to suspicious, come with me and then we solve this out!" she shouted making Izuku nervous he knew who the woman that was looking at him it was the number 1 heroine All might while Izuku cursed himself again for his bad luck that he just had to escape Izuku was not used to talking to other people much less heroes, he stood up and didn't answer he jumped and quickly flew away while All might was following him.


"Damn it! she is persistent!"

Izuku was trying to fly away from All might but she easily kept up with him he then had an idea he flew away from the buildings just as he was about to fly away a giant fist punched him to the earth making Izuku eat dirt. He looked up and saw a blond haired woman with the size of a building wearing a purple suit along with horns and a mask Izuku just fired a rocket at her it exploded when it hit her when the smoke went away there were only burn marks on her suit but Izuku flew again...but got grabbed and slammed into a building by some wooden roots before he could recover someone tackled him into the building further a woman with white hair wearing a light blue suit with black and yellow markings he quickly used his taser and shocked her away while firing his flamethrower at the incoming wood but the flames died down as another female hero shot water at his gauntlet Izuku switched to his force shield defending him from the water and used his other gauntlet to shoot her down with an energy beam.

"Where did they come from!" said Izuku madly who got tired getting tossed around by the heroes he stood up again and got punched in the stomach making him cringe a bit as he again got smashed in another building. Izuku had a long temper he was always calm but now he was pissed getting tossed around like a rag doll and this time he meant business All might tried to punch him again but Izuku caught her fist catching her off guard, using the moment Izuku threw her into a building and shot 2 rockets after her the giant lady tried to pick him up but countered by using both his gauntlets and tried to fire only to be halted by a voice.

"STOP RIGHT NOW!"

Izuku turned around to face the person but saw many heroes that was even impossible for him to escape Izuku sighed and put his hands in the air, he was scanning which heroes he fought inside his mask. "Jarvis who are those heroes?"

"Just wait a minute sir, here is a list of these heroes with their names.

All might.

Mount Lady.

Kamui wood.

Deathgoro.

Backdraft.

Ryukyu.

Midnight.

Ingenium.

Uwabami.

Gunhead.

Present mic.

Sir MOST of them are pro heroes and summoning the other suits is not an option the best thing we can do is surrender and wait for the consequences.

"Damn it are there no other options like fighting them!?"

"I'm afraid not sir some of the heroes attacks have no effect on the suit but they are far more experienced in combat while you never fought."

Izuku sighed with his hands still in the air while Deathgoro and All might restrained him while Kamui wood trapped him from the back with her roots. He was really pissed off but for a weird reason he recalled the blond girl he saved from somewhere but he couldn't remember at all from the amnesia, the heroes leaded him into a reinforced car and drove him away while the heroes who were restraining him were assigned to watch over him.


Izuku just scanned the heroes by reading what their quirks were and also scanned what there weaknesses were with their quirks without turning his head because the heroes were watching him it was silent until All might tired to start a conversation by asking some things.

"So are you human or robot?"

"..."

"Where do you live?"

"..."

How old are you?"

"..."

Izuku didn't answer any of the questions not wanting to reveal who he was and that he was a male he was a bit afraid what they might do with him but also wanted to know who he was he couldn't connect to the server from the hospital since it was heavily guarded and would track him down so he didn't take any risks, even if they found his hide out the suits were stored underneath the station there was a huge hole pipe that reached the ground of the sea so he stored all his suits there it was not even 1/10 full so Izuku was building suits to kill time.

"I'm human, where I live does not concern you and I'm 14 years old."

"Ahh! You spoke and wait! Your a male and your just 14!?"

"Yes, I am you got a problem with that?"

"No, but what is your surname?"

"I don't know."

This answer caught the heroes off that the young kid didn't know his surname they thought he was playing tricks with them but they detected a honest answer from the boy not any lies at all. Before they could ask more questions the car stopped they stepped out and stood before a massive building with the words UA standing on it Izuku groaned it was the hero academy where girls went to train with their quirks to become pro heroes they pulled him by a chain they bond on his hands together as he entered the school while they walked into the school many girls looked at him while Izuku felt really uncomfortable with all the attention on him focused.


They entered a room that was quite big but he saw also the girl that he saved who just looked curious at him they leaded him towards a chair and he sat down as they untied the chains and walked away the light went on.

"Can you please get out of your suit?" Izuku replied by saying "Jarvis." this made them confused but then quickly stood on guard as he moved while some parts of the suit retracted as Izuku stepped out of it and looked sternly at them as all heroes het shocked that they saw a boy coming out of the advanced suit they thought a man would be coming out of the suit except for the heroes who asked him questions but instead saw a boy of 14 years old who was quite tall for his age with messy green black hair and freckles on his cheeks and wore a simple plain white t-shirt and black pants and had a scar on his cheek.

"So kid what is your name?"

"My name is Izuku I don't know my surname though."

"How don't you know your surna-"

Before the question was finished someone tackled Izuku to the ground it was the girl with ash blond hair while shouting.

"DEKUUUU!" as the girl shouted with tears in her eyes while smiling.

"Ugh." Izuku felt all the air out of his lungs sucked away when the blond haired tackled but couldn't get any oxygen as he was smothered by her breasts making him suffer.

"DEKU! WHERE WERE YOU I WAS SO WORRIED I STILL REMEMBER WHEN YOU WERE CAUGHT IN THE EXPLOSION OF 6 YEARS AGO AND THE POLICE, MARINES AND HEROES COULDN'T FIND YOU!" sobbed the girl with tears in her eyes who just was happy she saw her childhood friend back as she looked down but saw him almost passing out from getting smothered, when she saw this she quickly let go and wiped her tears away and smiled sheepishly.

"PUAH! I thought I was going to die!" shouted Izuku who at the same time wondered how the girl knew his other name "So who are you and how do you know my other name?" as soon as he asked he saw the girl looking shocked and looked like she was going to cry again Izuku tried to calm her down by hugging her which she happily accepted.

"Uhm? can we continue the questions boy?" asked a woman with black hair while wearing a black white skintight outfit along with a red mask "Uhm can you get off me I can talk to you after I'm done." she replied by letting him go and walked back to her seat while still smiling the other women didn't know but they felt a bit jealous that the girl got hugged by the cute boy "so boy how do you not know your surname?" she continued.

"I suffer from amnesia the only thing that I remember is my name and a explosion nothing else."

This made the females murmur until the blond haired girl interrupted them again.

"It is reasonable that he doesn't remember anything I can explain his amnesia!"

"Okay girl can you explain please."

"Yes, anyone know the flight of Skydiver 2409 accident that was shot down by unknown reasons?"

All the women nodded it was a miracle since there was only 1 person missing.

"Well he there was the 1 that was missing I almost fell off but he pulled me inside by pushing himself off!"

The women looked shocked the plane flew 800 meters above the sea that was inhabited by dangerous sharks how he survived was a miracle while Izuku still didn't remember anything but it sounded reasonable since the girl knew his other name although he wondered who the girl was and who his parents are to "The explosion of Skydiver 2409 well that explains why I was lying on top of some metal." muttered Izuku to himself as he remembered that he lied down on a piece of metal before he walked towards the station. He felt a bit lonely those 4 years even with Jarvis he was really bored not interested in anything that he liked heroes interested him a bit but nothing besides heroes, quirks and science didn't gain his interests.

"So in short explanation the boy who went missing is this kid who somehow survived."

The girl nodded and went over to Izuku and hugged his arm who didn't mind at all.

"So kid this suit is pretty heavy, no offense but you look pretty scrawny to be able to move in this suit."

Izuku didn't take the comment kindly "HEY WHO'S SCRAWNY!" and with that he pulled his shirt off showing his lean and muscular upperbody. This action caught them all off but caused them to blush to some even looked at his body in lust while the girl next to him looked like a tomato drooled a bit. Izuku didn't understand why they were blushing but who can blame him he lived alone for 6 years and those years made him quite blunt not afraid to show his body to others so he put his shirt back on much to the dismay of the females.

"Plus if you want to know I built that suit myself."

"But how did you get the materials the metal you used is really expensive and from high quality and we already checked that no one bought these metals."

"I live in a old space station the metal was easy to get and with my intellect it was easy to create the suit but this is a old prototype in scientist eyes a jewel but for me a piece of scrap metal."

This made them all shocked that this was prototype that could tank a hit from All might and still can function and still fight the heroes on a standstill until they got reinforcements to make him surrender "So if you want the suit have it I have no use for it anyway I will just call Jarvis to get me back home."

Izuku said annoyed that he had to stay here for so long he was not happy at all if they wanted the suit they could have it! he hadn't any use for it at all his other suits could easily beat it plus this one had only standard equipment not that they knew it.

"Okay we got all the information we needed you can go home."

"Finally!"

"But Izuku your mother is worried about you! You should go to her first!" said the blond girl worried while said boy wondered how his mother was and seemingly from what the girl said only mother he assumed that he didn't have a father "So I have no father?" the blond girl nodded sadly "But what is your name I don't remember you I'm sorry for that." the girl smiled that he finally asked what her name was.

"My name's Katsuki but you can call me Kacchan!" she exclaimed happily.

"But where do I live then?"

"I know I live under the same roof as you!"

Izuku nodded they then were leaded to the exit by the heroes but stopped.

"Wait kid can you at least give us his adres where he lives so we can pick him up?"

Katsuki just nodded and wrote down on a piece of paper with the adres and gave it to the hero and walked away.


Earlier Katsuki dragged Izuku to buy some new clothes he wore now a long sleeved black t-shirt that hugged his muscular body along with black pants with neon green lines on it and also went to the hair stylist to cut his hair despite his protests she just straight up ignored him making him sulk a bit they were walking for a while Izuku didn't bother to look ahead he saw huge houses along the way and rich looking kids with expensive clothes but the weird thing was that most of the kids were girls while the boys tried to seduce them but got turned down immediately but rather pointed at him blushing as they saw his muscles being covered by his shirt while the guys glared at him.

"HEY BOY!"

Izuku turned around and saw an rich looking boy glaring at him obviously thinking his muscles were fake.

"So we have here a commoner huh! Well let me show you what we do with a commoner here right boys!" he shouted as several boys stood next to him smirking while Izuku didn't look impressed seeing that they ganged up on 1 person making them a shame of true men "Take this!" and the boy punched him in the stomach he smirked but then widened his eyes as he felt pain course through his fist and pulled back screaming with tears in his eyes making him look pathetic, Izuku returned the favor by punching him in the stomach making him double over and fell to the ground the other boys looked scared one who was brave enough to step up tried kicking him in the face but got his foot stuck by Izuku's hand who twisted it a bit and pushed him away making the boy fall to the ground.

Before they could attack again Izuku blasted them back with a shockwave the boy who was crying earlier spoke up "You bastard we will get you later!" but stopped when a shadow loomed over him it was Katsuki!

"K-Kacchan, h-how are y-you?"

But his response was answered by a growl and a menacing glare "How many times do I need to say it Dallas!" she then used her quirk to blow up a part of the street next to him making him whimper again "NO ONE EXCEPT MISS MIDORIYA, MY FRIENDS AND DEKU IS ALLOWED TO SAY MY NICKNAME!" as she held her hand which emitted small explosions close to his face making him look in fear.

"B-But wh-what is so s-special about him!?"

"He is my childhood friend! and also the lost son of Miss Midoriya!" she shouted madly while Izuku looked surprised at the reaction of the boy when she said 'Midoriya' he guessed that was his surname.

"WHAT!" shouted the rest of the boys who just got up looked terrified Izuku didn't know but his family name was really famous across Japan they were also good friends with many important families and on good terms with UA high and that they tried to attack a member of a high ranking family was a dead wish since they also had a lot of influence to the government the boys picked up their leader and apoligized for their boss and their actions and ran away with their tails between their legs Izuku looked at Katsuki and walked over to her.

"NO OTHER BOY IS ALLOWED TO SAY MY NICKNAME EXCEPT DEKU!" she thought menacingly she then felt a hand on her shoulder and looked up and saw Izuku concerned face "Are you okay?" that made her eyes water again as she remembered being almost beaten up by boys when Izuku saved her she then quickly hugged him and snuggled into his well build chest while the girls looked jealous but they were happy to see their friend way more happy then her usual temper.

"Well let's go home Kacchan!" she nodded happily and hugged his arm and lead him to his home smiling.


"So this is where I live!" exclaimed a wide eyed Izuku who gawked at the house he used to live in while Katsuki giggled at his reaction standing before them was a Japanese designed house that was 4 stories tall along with towers, pebble paths, river with a bridge that lead to a pavilion with pink lotus flowers in the water, bamboo trees that reached 4 meters along with a flower field of purple flowers, fountains in the shapes on tigers and dragons who spewed water in fountains with majestic orange white colored fish and a shrine with many important looking statues. Izuku thought if he was like those boys a spoiled brat which made him scared if he was that once.

"Well let's go!" as the iron gates opened and they entered they walked for 5 minutes and entered the house he took his shoes off like, Katsuki knowing there were etiquettes when they entered the house a woman appeared with long black hair that reached her back tied in a ponytail wearing a red white standard kimono she looked beautiful in Izuku's opinion "Welcome back Mistress Bakugou, who is the boy if I may ask?"

"I'm fine Ayami, the boy you ask this is Deku or in other words Izuku Midoriya!" as she saw Ayami confused at the name Deku she looked closer and remembered a boy with green black hair taking her hand along with the others to his home and got treated, offered a job and were allowed to stay here she teared up and threw herself at Izuku much to his horror as he got suffocated by her huge breasts "MASTER MIDORIYA!" she screamed happily seeing the boy who took her and her friend and family in.

"What is going on?"

"Something happining?"

"What's the noise here?"

Many doors opened revealing many beautiful curvy women wearing red white kimonos that looked like a bit to small for them.

"Master Midoriya is back!" exclaimed a happy Ayami out.

This made all the woman look at the boy who managed to free himself a bit from suffocation they took a good look on him and recognized their master and quickly went over to hug him while he just struggled to get out of there grasp while Katsuki looked extremely jealous that HER Izuku got hugged by many beautiful women and tried to pry them off him but they recomposed their selves after hearing a stern female voice.

"WHAT IS GOING ON HERE!" they all turned around to see a astonishing beautiful woman with curves that would make a model jealous along with black green hair that reached her back tied in a ponytail decorated with a lotus flower while wearing a black green kimono "Welcome back, Misses Midoriya!" said all women while bowing deeply towards her.

"As ease girls what was the noise abo-" she stopped her sentence when she saw Izuku in the middle she recognized him immediately the black green hair like herself the innocent look that looked like it couldn't harm a fly she teared up and ran up to him and hugged him close to her shoulder Izuku quickly figured out that this was his mother and hugged her awkward back while patting her back "Uhm sorry mom but I suffer from amnesia so I'm not being able to remember you at all." she just replied that it was okay as long as he was here she took him to a room followed by Katsuki and were talking and looking at pictures of his childhood until she called Ayami to lead Izuku to his old room.


"This is your room Master Midoriya!" Izuku gawked again at the display of his room it was big enough to hold 16 people it had a kings-sized bed along with a mini fridge, a plasma screen TV on the wall along with a DVD player with many CD's next to it it also had many game consoles, A mechanical wardrobe that seperate his clothing even his socks and underwear, a own bathroom with shower with TV, bath big enough for 10 people along with a hot sauna, 3 couches facing the TV, in the middle of the room a jacuzzi, aquarium walls with lots of tropical fish and real coral, a desk with computer that has 3 screens and as last a huge balcony with a small flowerbed and good view on the city.

"Ayami was I really this spoiled?"

"No you weren't at all!"

"Can you tell me how I was before I went missing?

"You were a kind person that would care more about other people rather then yourself but you had no backbone making you easy to cry and scared while you were also very shy which made it hard for you to make friends."

"Hmm." thought Izuku he was happy to discover who he was and that he was not a spoiled kid he looked at a bunch of notes and opened 1 and on it was information written on heroes he was quite impressed that he knew so much and decided to save it on his computer.

"Oh and Master?"

"Ok first of all don't call me MASTER and second Izuku or Deku is fine."

"As you wish Ma-Izuku!"

"Was I obsessed with heroes?" as he looked around to see posters of All might, Mt lady, Midnight and Kamui wood but blushed a bit when he saw the suggestive poses and decided that he would be removing them later not wanting to look like a pervert "Yes you were a bit obsessed with heroes at the point were it got bit annoying and scary." Izuku nodded again and activated his earpiece "Jarvis can you bring me MARK 4?"

"Already done sir, just wait a minute MARK 4 will be brought by MARK 2&3." replied Jarvis with amusement in his voice detected making Izuku chuckle and playfully rol his eyes "Ayami warn the others if they see 2 metal men flying towards the house that they don't attack them okay?"

She nodded and went away to tel it the others, Izuku went outside again and looked at the air and saw 2 men flying to his house and landed in front of him while at the same time Inko, Katsuki, Ayami and the other women came they saw 2 intimidating metal robots the left one was silver colored with blue on some parts and the right one was black and red while holding a suitcase along with a key he walked forward and gave the suitcase with the key to him "Thank you Jarvis! and also make a new MARK 1 just for model display please?" the suit nodded and flew back into the air with the other one following him.

"No problem those were my suits and Ayami can you get me a really advanced toolbox?"

"Uh yes I will do it immediately Master I mean Izuku!"

"Mom and Kacchan?"

"Yeah what is it Izuku/Deku?" Izuku gave them a soft smile which made them blush and the other women squeal with hearts in their eyes "When I have free time after school let's catch up those 6 years!" they nodded heavily at that they saw it was getting dark making Inko order everyone to sleep as everyone went to their room while Izuku placed his suitcase on the desk with they key next to it while smiling and fell asleep on his soft bed not noticing that Katsuki snuggled with only her panties and white button up shirt on in his bed and hugged him and laid her head down on his chest.

"I'm happy that your back Deku now that you have a quirk we can both still become heroes!" she thought before sleep took her away to dreamland while Izuku unconsciously hugged her tightly close to himself.


Alrain: Hope you enjoy the story if you don't like how OOC Katsuki here is this is my story so no hate if you don't like how Katsuki is so affectionate with Izuku until next time.
