Author note : Hello and welcome to portal hero my first attempt at writing fanfiction. I have no idea if this will be any good as I have never tried to write something like this but I think the plot line is at least good. The inspiration from this story originated within Kairomaru's fanfiction collector hero synthesis which if you have not read I highly recommend you check it out along with his other fics as he is a truly gifted author.
Plot summery (some spoilers hear)- What if Izuku had a quirk specifically a portal quirk now before anyone says it I am aware that the only real portal user we have seen in mha is kurogiri who is actually using a mix of quirks so Izuku won't have powers on his level. He will be able to form portals that go from point A to point B but he will at least in the beginning be slightly limited on the size of the portals he can make. With time and training that will get better but he wont be making portals large enough to send a small army through all at once like kurogiri does anytime soon. Also izuku will only be able to make portals within the area he can perceive unlike kurogiri who can make them to basically anyplace. Now that still gives him some impressive range as the human eye can see a pretty long way out but still I think these changes power izuku down enough that It can be a single quirk instead of multiple. The other thing to note is that In my fanfiction everyone will be aged up a bit and UA will be a university not a highschool. Lastly romance Wil be a part of this fiction as I am a romantic at heart but I have not yet decided who izuku will be parried with I have some thoughts but nothing is decided some feel free to leave your ideas and preferences about that in the reviews give me a good reason to pick your favorite pair and I mite just use it ( girls only I have no issue with yaoi but its not my jam and I'm not going to write it)
Ok now all of that's out of the way onto the fiction
I have now gone through and fixed the formatting in this chapter so its no longer a word wall along with other mistakes i saw its proably still not perfect but its better.
I don't own MY hero academia but if you really thought i did I'm sorry but you're an idiot.
Quirks, powers that humans began to develop over a century ago in some hands they are wonderful things in others they are dangerous and as Izuku Midoriya was about to learn in the hands of a child they can be both.
"Kachan, Kachan look" a four year old Izuku ran towards his best friend Katsuki Bakugo.
Izuku ran excitedly into their preschool classroom where Katsuki had been showing off his own quirk to the other students. The blond boy had unlocked his quirk a few days previous and it was an impressive one. The blond child had the ability to secret a nitroglycerin like substance from the sweat glands on his hands creating explosions at will. It was very exciting to watch and he was constantly being asked to demonstrate it by others in their preschool class.
Ever sense izuku had first seen the power Izuku had become obsessed with all quirks and desperate for when his own would appear.
" what's up nerd?" Bakugo asked the arrogance that had begun to form sense unlocking his quirk already showing.
" I got my quirk" Izuku was almost jumping for joy as he said this.
"ya?" Katsuki looked interested as he turned to Midoriya, these words also catching the attention of the other students and their teacher who gathered to see the new quirk " show me" Katsuki demanded "or is it one of those lame ass quirks that you cant really tell if somebody is using them? Like the guy in class who just vibrates his ears". At this a black haired boy in the group lowered his head as other poked fun at him.
"no " Izuku beamed " check this out" with that Izuku extended his hand fist closed then as he opened his hand a small hole seemed to open in the air its self. About the size of apple the hole was surrounded by a green swirling energy. Bakugo looked at the whole in the air curiously
" what that fuck is that" he asked using much stronger language then one would expect from a four year old but "fuck you" had literally been katsuki's first words and it had not gotten better from there.
His teachers had at various times tired to correct his rude language even going so far as to have a meeting with the boys parents. However upon meeting the boys mother they instantly realized where he got his vocabulary from and gave up on stopping him as a lost cause focusing instead of making sure none of the other children began to copy him.
Ignoring his friends cursing Izuku smiled and slowly inserted his hand into the hole in space the appendage disappearing as it entered. The class muttered impressed by the feat Katsuki was about to ask what happened to Izuku's hand when suddenly he felt a tap on his shoulder. Turning he and the class were surprised to see another matching hole in the air which had a hand sticking out of it. Izuku smiled as he wiggled the now floating figures.
"The doctor named it portal "Izuku explained. "it lets me open these hole things in the air and then you put something in one and it comes out the other one"
the explanation was simplistic but still enough that the quirk sounded impressive. At least to most Katuki didn't say anything at first but the rest of the class and the teacher all smiled and congratulated Izuku on his Quirk.
Eventualy even Bakugo gave a half smirk saying "not bad nerd can you make it bigger?".
Izuku shook his head smiling at the praise " not yet be the doctor said if I work at it ill be able to make them bigger and farther away."
The class was even more impressed at this warping quirks were rare and they could all imagine the potential for such a power. Wile it seemed like a nice moment it was also the moment when things went wrong.
One of their class mates patted izuku on the back alittle too hard and broke his concentration causing the portal to close this wouldn't have a problem except for the fact that Izuku still had his hand in it. The floating hand fell down on top of Bakugos shoulder before dropping to the floor and blood began to spill from Izuku's forearm.
For a moment all was silent as everyone tried to process what had just happened eyes going to either the hand laying on the floor the blood pouring out of Izuku or the puddle of blood that began forming under him. After a few moments of silence, the coin dropped and people began to react.
As one might expect from two dozen four year olds when faced with such a scene they began screaming, crying, or generally panicking. All except for Izuku and Katsuki the former was just staring at his bloody stump in shock and the latter was laughing hysterically thinking that the incident was deeply funny. A fact which when they through about it latter the teacher would find very disturbing and concerning for Bakugos mental health.
The teachers got over their shock and rushed into action an ambulance was called and Izuku was rushed off to the hospital along with his hand despite Katsuki asking a slightly disturbed paramedic if he could keep it. Midoriya's mother was called and Inko Midoriya may have broken some speed records running to the hospital. The staff informed her that her son was in surgery and directed her to the waiting area.
A few hours later Inko was still sitting in a waiting room along with her best friend Mitsuki Bakugo who after learning about the incident from her son had rushed to the hospital to be with her friend and child who she saw practically as a nephew or even a second child knowing that Inko would need support and her husband Izkus father had abandoned them a year prior.
Mitsuki and inko had been best friends sense they were in middle school they did everything together they worked together at a modeling agency they spent most of their free time together, they had gotten married together and then ironically got divorced together when both their husbands ran away at almost the same time. They were so close they had often been mistaken for a couple themselves and wile one or the other of them may have wanted that at various times neither had ever told the other as much and so had remained as friends. Inko had red eyes from crying and was sitting in the waiting room chair her hands holding Mitsuki's tightly as they waited for news, just as Mitsuki's hands were starting to go a little numb was when a nurse approached them.
"Midoriya?" the nurse , a short woman with light green skin and dark blue hair, asked. At Inko's nod the nurse smiled "Izuku is stable now he is being taken to a room up on the third floor I can take you to him now the surgeon doctor shoji is waiting to brief you."
After being led to his room Inko and Mitsuki saw Izuku sleeping in a hospital bed his mother ran to his side so quickly the doctor, a tall women with silver hair and six arms, who had been waiting brief them assumed she had a speed quirk. Over all Izuku seemed fine but his lowerarm was wrapped in thick gauze bandages making it hard to tell if there was a hand attached or not.
Seeing this Mitsuki asked the question for both of them. " how's his hand doctor were you able to save it?"
the doctor sighed at this shaking her head sadly. "Unfortunately when Izuku's hand was lost it was not so much cut as it was crushed until it severed. The blood vessels nerves and muscles that would have been needed to reattach the hand were to badly damaged."
Tears began leaking from Inko's eyes hearing that but Mitsuki quickly wrapped an arm around her. "at least he is ok Inko" she encouraged the women " and they have made great strides with prosthetics technology in recent years rite doctor?"
The surgeon nodded " that's correct mam prosthetic limb technology and robotics were some of the few that didn't slow with the start of the quirk era with Izuku will need to have his updated every few monthss as he is still a young man but with the rite model he will be able to live a normal life. Ill arrange for our local prosthetics expert to come see you hear in the hospital tomorrow as we would like to keep Izuku for a little bit to make sure there isn't any infection or complications"
Inko just nodded at this still running her hand through the sleeping boys hair Mitsuki continued in her role as the less emotional one putting a hand on Inko's shoulder " when can we expect him to wake up doctor?" she asked knowing Inko would be much less upset when her boy was awake and reactive.
"He should be coming to very soon in fact I expect within the next half hour. I'll come back tomorrow with the prosthetics maker so we can set up the procedure to have it attached but if you need anything in the meantime just let the nurses know and do my best come back sooner."
The mothers nodded at this and doctor shoji left the room. Mitsuki placed both her hands on Inko's shoulders gently massaging the crying greenet as she pulled her off her knees. "you will get your outfit dirty if you stay on the ground Inko honey why don't we grab some chairs and we can wait for Izuku to wake up I can called a babysitter for Katsuki so I can spend the night hear with you if you like.
Inko just looked at her best friend before rushing into her arms holding each other closely as she thanks Mitsuki over and over again for being their for Izuku and for herself. Mitsuki just laughed at this her hands running through the shorter women's hair as she held the trembling women into her chest. "don't be silly inko we have been together sense middle school of course I'm going to be hear Izuku's like another child to me and I know you feel the same about Katsuki"
Inko nodded her face still pressed into Mitsukis large chest and it was at this moment she felt a courage like never before to follow the desire she had on and off sense high school. "Mitsuki" she said and when the blond women looked down Inko stood on her toes and kissed her best friend rite on the lips.
Mitsuki was stunned for a moment before quickly leaning down slightly and returning the kiss her arms wrapping tighter around Inko pulling the women close into her body. The two women stood there happily holding each other and lovingly making out and this was the first thing izuku saw as he woke up however his four year old brain couldn't processes what he was seeing so he did that natural thing and passed out again.
