A full moon happens approximately every month. Midoriya Izuku was never outside to gaze upon the glory of the unveiled pearl in the black sea. The truth is, Izuku wasn't quirkless. He was something else, something more… Feral. And considering he was thought to be without powers for close to 120 lunar cycles, he was also quite unlucky.
Midoriya Inko was a mother that was well-accustomed to shame.
Ever since that day, where her son was given the terrible fate of being normal.
Normal in a world where everyone was extraordinary.
The moment where the doctor ruthlessly explained that her son would never amount to anything. Everything that he valued crumbled. They robbed away his dreams from him. Everyone did.
And she could do nothing but say 'I'm sorry', crying while trying to embrace him when he asked her if he could still be a hero, watching the same video of his idol repeatedly—the state of the disc reflecting his own; broken.
Back then, she wished she could protect her quirkless son from the outside world forever. But that was a sick lie.
Here she was, every time that her son came back home from school, each day sporting a fresh injury—either a bump, a bruise, or a burn—like a medal marking his lack of something.
The handicap he was born with was laid bare for everyone to see.
But her brave son pushed through it all. He powered through school, despite the insults, despite the scold, despite the shame and despite the scorn—enduring it all to the end.
There was a time where Inko allowed herself the inkling of hope. Her son's bullying had started soon after his classmates had realized that despite being well over 4 years old, he still had shown no signs of his quirk. For cruel and bored kids, her Izuku was the best target possible.
It wasn't hard to see that Izuku healed from his injuries slightly faster than usual, or that he had always been taller than normal. For someone that barely exercised, her son was also always in shape.
Unwilling to give her son false hope, she had rushed to the same doctor, hoping he would conduct new tests in the light of this revelation.
The results? Well, Midoriya Inko had to bite her lips when she heard the familiar ring on the door.
She checked the clock and mentally nodded. Izuku is right on time once more…
Her steps were hesitant, and her fingers trembling.
Inko was a mother who was afraid to see her own son, and that was what hurt her the most. She could never give to her son what he wanted, and the sight of his hunched back, his flat eyes, and his slightly depressive demeanor were all scathing reminders of her failure.
Something needed to change the current situation.
And that something ended up being a villain.
Holding the burned notebook close to his torso with both of his hands, Izuku dawdled along the way, desperately trying to look for any page of his book that was still salvageable.
Reaching a tunnel, only one thought was in his mind.
Kacchan… You jerk.
As a quirkless child, Izuku had to get used to the constant bullying he faced.
But it didn't mean that it didn't hurt anymore.
Even his childhood best friend Katsuki Bakugo targeted him regularly, taking out his anger on him.
His ex-best friend, Izuku mentally corrected, was probably the cruelest of them all, often time being the spearhead and the leader of the bullying campaigns against him. Throughout his time in the public system of schooling, Izuku had suffered some of the most dangerous forms of bullying, both physical and mental.
After all, the world wasn't kind to a quirkless person. Even when being cornered by multiple students armed with powerful quirks. While there were multiple restrictions placed on the public usage of quirks, who would believe the quirkless child?
No, Izuku winced. It's not that they don't believe me, it's that they don't care.
Lost in his increasingly darker thoughts, Izuku didn't notice the gooey, mud-like substance erupt from the sewer grate right behind him. Of course, by the time he heard the ringing noise of the knocked-over metal repeatedly clattering against the ground, the bulbous mass had already enveloped him.
"Wha-"
The villain stopped his every movement by surrounding him with his own body and formed a tendril that slowly entered Izuku's opened mouth.
"Don't worry." The disembodied voice of the blob rang through Izuku's ears. "Everything will be over soon, just let me take over your body nicely and nothing bad will happen to you…"
"HMPH!" tried to scream Izuku. I can't… Breathe!
Izuku desperately tried to grab the glob that was blocking his airway. He struggled, the grating laugh of the villain haunting him as the feeling of a liquid passing between his fingers. The lack of oxygen became critical.
"I'm fluid! It's impossible to grab me with your hands," said the villain with an irritating, smug tone.
Not that Izuku had the luxury of complaining about his tone as his vision darkened and his wiggling slowed down, although his clawing became more frantic.
I'm... losing my strength!
"I have to thank you for your help… I didn't think that he would come to this city after all."
But before he truly fell unconscious, before he truly relinquished the hold of his body over the villain, his ears perceived a voice he couldn't believe was true.
"There's no need to fear anymore, young man!" The tone was deep and full of confidence. From the TV shows to the action figures, this voice was one belonging to a hero that shaped this very society.
"What?!" The Sludge jerked his head around at the sound of his voice.
"Because I am here!" It was Izuku's idol, All Might.
Before the Sludge could react, All Might dashed in front of him. The very muscular man's speed catching the villain off-guard. He only tried to lash out with another tendril and make some distance, but it was already too late.
"Texas…" All Might drew his elbow back, putting his body in the correct position to throw a punch. He simultaneously drew from his inner wall, the sputtering flame left in him.
"Damn it!" Desperate, the villain tried to engulf All Might as he did with Izuku.
"Smash!" But it was all useless. The hurricane unleashed by the power behind All Might's punch evaporated the villain, letting splatters of his main body crash against the walls of the tunnel.
His vision blurry and his lungs trying to process the sudden influx of oxygen, Izuku huffed, his eyes locked on the ground. Then, remembered just who saved him, he abruptly stood up to gaze upon his glorious idol.
"Are you okay, young man?" All Might asked, his voice dispelling Izuku's suspicions that this was just an elaborate dream and that in reality, his body had become a puppet of the villain.
"Y-y-you're ALL MIGHT!" Izuku squealed in a high-pitched tone, his inner fanboy taking over at the sight of the greatest hero standing in front of him.
In response, All Might simply grinned, displaying his shiny teeth, and gave him a thumbs-up. "Yes, I am!" He said, in distinct English.
The green-haired boy let out yet another acute yell, his cheeks visibly red before he realized how embarrassing he was. "I-I'm so-sorry All Might, it-it's just that I-I'm a big fan of yours," Izuku stammered, his social anxiety slowly taking over. "A-And I w-would, PLEASE GIVE ME YOUR AUTOGRAPH!" He screamed, sharply bowing to the number 1 hero.
"... It's already done," simply answered the muscular man, his signature smile eternal on his face.
"Huh?" blurted out Izuku, before realizing that in All Might left hand was his abused and slightly burned notebook.
"Here you go." All Might tossed the notebook to the green-haired student. "I'm sorry, for most of the time villains don't escape me, but I was so excited about being in a new city that I made a mistake!"
His words were accompanied by a booming laugh that brought Izuku out of his dreamy gaze towards All Might's signature being in his notebook.
"T-t-t-thank you very much, All Might!" Izuku bowed once more, this time ever lower than before, making All Might's smile widen a little at the sight.
"Now, if you'll excuse me, this city is not free of crime yet, and it is my duty to fix that problem!" the top hero declared, stretching his limbs, ready to jump through Musutafu once more.
Ah, wait… I still have many things to ask you, thought Izuku, seeing All Might ready to depart.
"Well, then… I'm counting on your continued support!" shouted the muscular man.
His body moved before his mind could think, and the next moment he was flying—the rush of the wind painfully hitting his face as he could not stop himself from crying because of the All Might's speed.
As Izuku blitzed through the city, at a speed not even the most advanced cars could reproduce, the grasp he had on All Might's leg being the thread between life and death, no one could say that Izuku didn't display a particular amount of bravery.
That was the start of Midoriya Izuku's carrier as a hero.
"Come one, young man—this beach will not clear itself!" stated All Might in his muscular form, resting on a lawn chair he had brought and observing leisurely the young Izuku break himself under the strain of the massive amount of garbage piled up here.
Over the weeks, since Izuku discovered All Might's secret and was deemed worthy of being his successor, the top hero had worked Izuku to the bone, going as far as implementing a cruel training routine in his life. For someone who had barely exercised before, Izuku felt like he would die by the end of this training for the first few days.
Ironically, his body adapted fast enough to keep up with the intensity, and the slight definition his body presented was proof of that. But then again, Izuku always knew that he healed slightly faster than others and his body always stayed in shape—a pitiful compensation for being robbed of the opportunity of having a quirk was what the green-haired student thought it was.
Because All Might realized that his progress had vastly surpassed his expectations, Izuku already possessed the legendary quirk: One For All, passed down from the Symbol of Peace himself.
Though he did not know how to use it yet. All Might's vaguely primitive explanations didn't help Izuku, but he was happy that the number one hero at least tried.
Because of his experience, Izuku couldn't help but think deep down that his inadequacy stopped him from using the quirk that he had been generously gifted.
I get a second chance in life… A chance to become the hero I always wanted to be, and of course, I'm too useless to even make the first step, thought Izuku, tears threatening to come out as he carried another very heavy garbage.
All Might, sipping on his favorite beverage, unaware of the mental turmoil his disciple was undergoing, looked at the full moon above them.
The sound of something very heavy falling on the beach with a heavy thud broke him out of his reverie.
"What?" He looked down from his position towards the green-haired student currently transfixed by the moon.
In an instant, he climbed down from the mountain of garbage his lawn chair was on and approached the young man. "Are you alright, Midoriya?" He asked, getting increasingly worried about the lack of answer and the wobbly stance of his successor.
Trouble, All Might realized, well versed as a hero in abrupt changes and troublesome situations.
And he was right. The next instant, Fur erupted all over Izuku's body. His frame grew in all directions until he towered over All Might himself. The width of his torso—No the width of his body was distinctively not human.
The cracking noise of his bones shifting was grating and unpleasant, but All Might ignored that and prepared himself for the worst. Young Midoriya shouldn't have a quirk after all.
Stumped, All Might watched as Izuku's mouth gained in length, transforming into a muzzle filled with sharp fangs. His limbs contorted, granting him deadly claws, and giving him a bestial aspect.
The thing in front of the top hero groaned in a distinctively deeper voice than Izuku's.
The sand parting and the small particles breaking as the young man's body grew. His transformation finished a couple of seconds after it started.
All Might, mouth wide open, watching with a certain fascination and a good amount of caution the new form of his disciple. A theory appeared in his mind.
Still looking at the new moon, the newly transformed werewolf took a deep breath…
And howled.
With the help of the English language and in a distinctively American accent, All Might whispered, "Great, my disciple just happens to be a fucking werewolf…"
