Hello everyone, to the first ever piece of writing to leave the bin that is the dead concepts in my head. I've had loads, but this one seems to speak to me in a way the others didn't. It involves our favourite broccoli haired boy wonder, Izuku in the escapades following my take on the very popular question:

"What if Izuku had a Quirk?"

The answer: A lot of Hijinks and things not going to cannon is a guarantee. Certainly. I'm just a bloke writing fanfiction. Not Kōhei Horikoshi, and so there will be deviations. And a lot of them. But I promise you all that to the best of my amateurish abilities. Everything will serve at least some purpose. Grand or small? Who knows, but nothing happens without a reason.

With that said, the Quirk in question, as the title is unsurprisingly revealing: Nanites. A form of Nanorobotics which Izuku will be capable of creating out of virtually any metal, a devouring swarm of sorts, with the ability to form into virtually anything his very creative mind could come up with. It's exact abilities are to be explained and explored throughout the series. But I admit. He'll be powerful. Very much so. OP as some like to label it. But then. When a good chunk of the antagonists in the series have incredible abilities like Stealing other's powers. Disintegrating ANYTHING they touch with all five fingers at once, and shoot blue flames from their hands with which to scorch anything they so desire? I do not believe it's completely unreasonable.

Normal Speech: "Nanites!"

Normal Thoughts: 'Nanites?'

All Might / Monstrous Quirks Speech: "NANITES?!"

All Might / Monstrous Quirks Thoughts 'Nanites!'

All men are not born equal. This was an undisputed fact of life, in this world. A young boy, three years of age, with messy green hair and bright green eyes had come to realise. This World of Heroes and Villains. This world of Quirks. The Origins of which still remained a mystery as to how exactly they came to be. The most popular theory was that it was the next stage in the evolution of humans, for while in the majority of the cases, the offspring of Quirk wielders inherited a form of their parents quirk, either from one of them, or a combination of both. And usually stronger, every few years the rare occurence of a completely new Quirk awakening with no similarities to the Parent Quirks. A Spontaneous Quirk.

But when some are born as regular old humans without anything unique to them, are stacked up against people with extraordinary abilities such manipulating concrete or sprouting wings. There is always going to be divisions. Such divisions can lead to gifted individuals believing themselves greater than the masses. And using their gifts for selfish reasons.

One such selfish act occurred when a Villain with freezing quirk, attempted a Quirk Point Robbery in Downtown Shizuoka one afternoon. And it, like so many others, went awry due to no hero with 'The right Quirk' being around to stop the Ice Villain who had taken so many people hostage. Including one Inko Midoriya, mother to a bright young boy three years of age, and eagerly awaiting his own quirk to manifest itself.

And as they went back and forth, negotiating for the surrender of the Villain, and the release of all his hostages, a security officer took the opportunity which had arrived from a moment of confusion, to strike. And fired at the Ice Villain, this unfortunately did not incapacitate him. But rather caused him to panic, and use his quirk to its fullest abilities. The Bank was frozen solid. Everyone inside, frozen from the inside day, the fourth of March. Izuku Midoriya, lost his mother in a random act of violence in which she was an innocent bystander.

The months that followed, poor young Izuku lived as a shell of his former self. Having lost his Father Hisashi when he was still a baby, he had no immediate family to rely on. And instead hei was placed under the protection of his Grandfather. A man he had never met. Going only by the name Sorahiko or his hero name: Gran Torino, young Izuku came to call him as "Grandpa Torino!"

"Yes Izu?" The tired, irated voice of an old man, mentally unequipped to handle a grieving toddler. "I.. Had a Nightmare about mom again." A young, saddened and emotionally drained Izuku said. Standing in the Doorway of Gran Torino's own bedroom. He was clad in his trusty All Might PJ's. A sight that filled Gran Torino with no shortage of amusement. Sighing, more to himself than in irritation of the very reasonable occurrence, that admittedly had happened far more often than he'd have liked. Gran Torino had to admit, it hurt looking at a saddened child like this.

"Then quit standing in the doorway and get in here. You have to be fresh for tomorrow. We're going to visit a doctor and find out what your Quirk is." He said. Both Grandfather and Grandchild could not deny, that despite the sombre mood that had persisted throughout young Izuku's stay with the eccentric old man, that both were very excited what Young Izuku's quirk could do.

"Okay Grandpa Torino." The young boy said, crawling into the bed alongside the old man, who protectively embraced the only slightly smaller figure. "Love you Grandpa." He whispered tiredly as he slowly drifted off to sleep.

"Love you too squirt." Torino said. Closing his eyes and letting sleep take a hold of himself as well. Not knowing what the morning would bring.

And as morning did arrive. The two went through the daily routine, with at least a little more life to it than it had previously. The Slightly Rundown Gym was abuzz with activity. Sorahiko preparing breakfast for the two. While Izuku squirmed in excitement. "Squirt." Sorahiko called out. "We'll swing by your parents before meeting with the doctor. Is that okay?" He asked carefully.

Izuku stilled for a moment, before nodding his head quickly, blinking away the tears threatening to form. "Okay Grandpa Torino" The young four year old child responded.

And so they did. After eating breakfast, the two boarded a train and headed for Shizuoka where Inko lay buried next to her husband Hisashi. Midoriya stood before the tombstones, teary eyed and on his knees. "Mom, dad. I'm going to find out what kind of hero I'll be.. I.. I promise I'll make you proud!" The four year old declared, his tears staining the gravelled pathway he kneeled upon. Sorahiko placed a comforting hand on his shoulders. "Go on ahead Izuku, I'll be right there with you. See if you can't beat your previous record?" He said, trying to cheer the boy up. Izuku nodded, and sped along, as swift as his small legs would carry him.

Sorahiko remained. Looking at the two graves with a steely determination. "Hisahi. I admit I was a terrible father to you. But I swear to you and Inko. That I will protect Izuko with all that I have. And I'll help him in any way I can." he said, somberly as he trugded down the path after the young boy.

An hour later, we find Izuku and Sorahiko meeting with a Quirk Doctor. Someone specializing in researching and helping those with quirks. "I have good news." The doctor said, holding up an X-ray of Izuko's foot. "Izuku doesn't have a joint in his little toe, something we've observed only occurs in people without a Quirk. Now we only need to discover what it is. A DNA test might help us discern that. But can I ask you, what types of Quirks did his parents have?" The doctor asked, carefully as to not broach an uncomfortable subject with the young boy, who was currently seeing stars at being told that he did have a quirk. He had already seen so many of his friends in the kindergarten awaken theirs. He couldn't wait to learn his.

"Sure." Sorahiko said, scratching his bearded chin. "Let's see ah yes. Hisashi inherited his mother's quirk. Fire Breathing. And Inko had a weak telekinetic quirk or something along those lines." He listed off, to which the doctor nodded along, writing a few notes. "I see. Well that does give us an idea of what his quirk might be." The doctor noted, reaching over to grab a blood extraction kit. "Izuku, would you mind pulling up the sleeve of that super cool All Might shirt you're wearing so I can take a sample?" The doctor asked him.

Izuku nodded hesitantly, eyeing the big needle with fear. But as he did so, he remembered watching All Might on television talking about the importance of trusting doctors. "Remember kids! Doctors are here to help us! Without their tireless work many people would not be alive! They are true heroes!". And as any impressionable young child knew, the words of All Might were never wrong. And so he stuck out his arm and waiting for the prick of the needle, eyes shut as to not see the blood. A tear already threatening to form. As it rolled down his cheek he kept waiting, until he heard a set of gasps, from Grandpa Torino and the Doctor. 'Did something happen?' young Izuku wondered, as he hesitantly opened up his eyes. And watched in amazement as small sparks of what looked like blue lightning sparked from his arm, up at the needle, as it seemingly evaporated into a metallic mist. And he felt something at the edge of his immature consciousness, prodding.

Acting on instinct, the small boy reached out with his mind, and when he did so, he could feel the msit. Hesitantly he willed it to move. And the small swirling cloud of metal began moving, seemingly on its own. As if propelled by small, unseen engines. "Remarkable." The doctor muttered. "I've never seen such a quirk before!" He exclaimed as he stood up. The action breaking Sorahiko from his stupor. "That's certainly not what I expected, the old man noted." Staring at Izuko continuing to play around with the mist. A sense of wonder on the small boy's face. The brightest he had seen the boy be since first meeting him.

The doctor, grabbed a specialized petri dish from a nearby table. "Izuku, do you think you could direct some of your mist into this, so we can have a closer look?" He asked, holding it out. Izuku managed to direct a small portion of the mist towards the doctor, who captured it. And placed it beneath the Microscope. After some fiddling he exclaimed a triumphant "Aha!"

Sorahiko looked at the doctor in interest. "What did you find, doctor?" He inquired curiously. "It seems that your grandson can create Nanites simply from being in the vicinity of metal. His quirk must have activated due to the anxiety of being stung by a needle. Interesting." The doctor mused, before digging an empty can out of his bin, completely harmless. And Setting it down next to a still awestruck Izuku. "It doesn't appear to be happen automatically. Izuku." he called out, and the young boy looked towards him curiously. "Try and see if you can't turn this can into more of the mist, okay?" He asked kindly.

Izuku nodded his head. "Okay." he responded, his attention now fully on the can. Starring it down, he waited, expecting the sap to occur instantly. And when nothing happened he frowned. 'Come on! Why won't it work, become mist!' he cried within his mind, huffing in frustration he continued, until he felt something within his consciousness, similar to the mist, but different. Like a small stream flowing through his body. When he tried to pull at it, another spark of electricity shot out, and struck the can. And it too became vaporous metal.

"Congratulations young Midoriya." The Doctor said to him. "You've developed a spontaneous quirk. Nanites." he said, smiling brightly down at the child. "Nanites? What's that?" He asked curiously, emerald eyes focused on the swirling grey mist of metal. "Nanomachines, son." The doctor explained kindly. "Small machines you can create, and seemingly control with your mind. We don't know the exact limits of your quirk. But I'm sure you'll find out what it can do in time."

"You're just full of surprises aren't you squirt?" Sorahiko mused. Then Izuku looked at him, at them both in fact, and with a quivering lip asked them both. "Can I become a hero?" He looked so small and fragile, it tore at Sorahiko's heart, the doctor meanwhile just smiled brightly. "With enough training and dedication. I am certain you will can." Izuku nearly began crying when he said so. The words of encouragement were exactly what he wanted. Then Grandpa Torino surprised him, enveloping him in a hug. "If you're going to be a hero. We'll have to train you to get in top shape. A flashy quirk won't be enough. But if you follow my guidance. You'll be among the best Izu.."

At this point, young Izuku Midoriya, four year old wielder of the Quirk: Nanites, was bawling his eyes out from the sheer happiness. His grandpa believed in him too!

Unbeknownst to anyone. It was at this moment the greatest Hero to ever live took his first step towards his destiny. Even as the Nanites powered down and behaved like little more than dust.
