As shown, this was going to be an MHA x Naruto fanfic featuring Sasuke as a main character alongside Izuku. I don't know where the inspiration went for this, but I must have dropped it at some point as you can see it cuts off at the very end. I think the plan was to have Sasuke want to intervene when he sees Bakugo getting merc'd by the slime guy, but deciding to watch instead when Izuku gets involved. He and All-Might end up having a rivalry of sorts as they both try to train Izuku in their own philosophies of being a hero.
Of Villains and Men
Bleary dark eyes watched their surroundings as the man walked his way to work. Work; he outwardly scoffed at the ridiculousness of his situation, drawing a few gazes his way. He didn't mind in the slightest, however. He was used to the stares, and he couldn't care less what others thought of him. The once proud man now reduced to checking out groceries for these people. If the idea wasn't so irritating, he wouldn't have minded as much. This was something that he would have done when he was thirteen, not a fully grown adult. Yet, here he was, on his way to do just such a job. It was demeaning. It was insulting. It was the only legal course of action he could reasonably take.
That thought in mind, he watched above as some wood-based Hero, Kamui Woods, he believed the boy's name to be, swung above him. No doubt on the way to battle some crime. It was an occupation he'd much prefer, rather than dealing with driveling idiots and their coupons. Still, almost a year with no way home had made him surrender his pride and take up a boring, standard, non-combat related job.
"That doesn't make this any better," the man muttered aloud to himself. He kept his hand in his pocket, and his black cloak over his torso. There was no need to draw attention to his missing arm. He was sure it wouldn't be the strangest thing that the people here had seen, but an amputee was still a rare sight in a world of Quirks. Ah, yes, it was Quirks here as opposed to chakra. Most of the population was born with a unique inherent talent or skill or feature, named a Quirk. When he'd first accidentally sent himself to this... place, he'd passed himself off as someone known as Quirkless; that is, someone with no overly defining talent or feature. It had been a new experience and a shock.
He was treated as if brittle, and pitied by the law enforcement officers that had taken temporary custody of him. It appeared that being Quirkless was something of a curse in this land. After all, unlike how chakra could be freely learned in his home given the right motivation and practice, Quirks could not be freely given or taken. It was just a known fact of this world.
The man paused as he heard a commotion coming from a nearby school building, followed by what appeared to be a notebook flying out of one of the building's windows. After a brief look around to ensure that nobody was watching him, he quickly leapt to intercept the book. Just in time, as well. Had he not done so, it likely would have fallen into a nearby fountain. It was already scorched. Judging from the nervous cries he had heard just prior, he had to assume this was likely some schoolyard bullying. Dark eyes narrowed, and the man decided to wait.
It wasn't long until a young man, probably no younger than fifteen, wandered out in his direction. His head was on a swivel, as if searching for something. The boy was distraught; his notebook had to be out here somewhere! He could only hope it didn't land in one of the foun- Izuku Midoriya froze as his eyes met those of the tall, intimidating man standing just outside of his school. For a moment, neither of the two spoke or moved; Izuku out of terror and the man out of observation. The boy was nothing special, and his left eye spotted none of the natural energy coursing through the other people in this world that held Quirks in this boy. He was as normal as they came. The question was, why was he so interested in analyzing Heroes? He let out an inward sigh and let his eyes relax for a moment.
"This is yours," he spoke curtly, allowing his hand to move from under his cloak. In it was the boy's notebook. Izuku's eyes widened as the man slowly handed his possession back, nervously shifting his eyes between his treasured notes and the man's face. It was impassive and impossible to read, so he only had faith to go on about the man's intentions. "Well? Are you going to take it, or not?"
"R-Right!" Izuku quickly shifted forward to take back his possession, grasping it with both hands as he gave the man a slight bow. "Thank y-you, sir!" The man grunted in response, and Izuku lifted his head slightly to see what this man's expression was. Still, it was impassive and his attention seemed to be elsewhere. "Um... Excuse me..." Dark eyes landed on the boy, making him flinch. "W-What's your name?"
Again, there was a long and heavy silence. Izuku could feel tangible pressure in the air around him; though he wasn't sure if it were actually there, or if his terrified mind was playing tricks on him. After what seemed to be long minutes later, the man spoke, "My name... It's Sasuke Uchiha." Izuku silently mouthed the name under his breath. It was a strange name to be sure; definitely more unique than his own. "You're Izuku Midoriya." It wasn't a question.
"H-How..."
"Your notebook," Sasuke replied with simple ease. "It has your name on it."
"O-Oh, right... Sorry, I should have assumed-"
"You were being bullied not long ago, weren't you," once more, the man didn't seem to be asking a question so much as stating a fact. As much as Izuku wanted to vehemently deny the truth of the matter, he felt as if lying would only make things worse than the surprisingly mundane, if tense, present. Still, he only gave a brief nod in response.
Sasuke looked the boy over once again, this Quirkless Izuku Midoriya. He was a mousy boy, easily frightened even by the slightest hint of Killing Intent. Still, the pages in his notebook were commendable, even if he'd only skimmed a few of them with his Sharingan. Advanced notes and strategies based on Quirks the boy rightfully should have no idea how they operated. He was a genius hidden inside the body of a weakling. For a moment, the Uchiha's mind flitted to his brother in all but name and blood.
"What is it that you want to be?" he decided to ask a simple question. It was astronomically improbable that the two were anything alike, but if they were...
"E-Excuse me...?" Izuku stammered at the question that seemed to come out of nowhere.
"Your goals, what are they?" the man asked him. For a brief moment, Izuku wondered if he was speaking to a Hero. After all, most normal people didn't ask those kinds of questions out of the blue. Still, if he were a Hero then surely Izuku must have heard of this man. But the boy couldn't recall anything about a Hero like this besides possibly Eraser Head, but even then, this didn't seem like the same person. "Stop your mumbling."
"S-Sorry," Izuku hadn't even noticed, but apparently he'd begun thinking out loud under his breath. "I... I want to be a Hero. I want to save people and help those who can't help themselves." For a moment, the man looked interested.
"What's your reason?" he continued to ask. "Money? Fame? Creating a legacy of some sort?"
"I just... I just want to h-help people... Uh, sir..." Izuku looked at his feet, feeling self-conscious as he spoke his thoughts out loud. "L-Like All Might or-"
"Hn, All Might," the blatant disdain in the man's voice drew Izuku's attention. "That man is nothing more than a loudmouthed idiot that doesn't know when to give up." Despite the harsh words and tone, Izuku thought he saw the barest hints of a smile on Sasuke's lips. "However," Izuku's attention immediately snapped back into focus. "You don't have a Quirk, do you? You're just a no-good, dead last loser."
Izuku felt his fists clench. Of course he was. He was nothing but a kid with dreams bigger then himself. But... Why did this man make him feel so angry to admit it? Bakugou and the others at school always made fun of him, but it never made him feel like... this. "I know I am... But... I-I'll still dream of being a h-hero! I know that I'll h-have to work harder then anyone else, but I-I... I...!"
"Hn, so you do have some spirit in you," Sasuke took a deep, slow breath after speaking. "That's good. I think you can make that dream a reality." Shock filled Izuku's body, his veins feeling frozen at the words Sasuke Uchiha seemed to speak so easily. This person, who called him a dead-last loser, believed he could be a Hero? Even knowing somehow that he didn't have a Quirk?
"H-How can you know that?" Izuku asked, not sure if he could believe his ears just yet. Sasuke grunted, before turning away from the boy. He had work to go to, after all. Before he left, though, he parted with an answer for the boy.
"Because you remind me of a loudmouthed idiot I know."
With those parting words, Sasuke made his way to work. It was only a short distance away, but his short discussion with Izuku Midoriya had taken more time than he'd anticipated. It wasn't long until Sasuke arrived at his destination, but given the looks he was receiving from his fellow coworkers, he was late. Again.
"Uchiha!" the voice of his employer boomed throughout the store, making him wince despite himself. "You're thirteen minutes late!" If it weren't for the overwhelmingly superior quality of the store's products, Mr. Usagi's Quirk, Boomvoice, would have scared most shoppers away from this particular store. It was a limited Quirk that allowed the frankly rotund man to shout through any speaker within forty feet of himself. It was annoying more than anything else, but it seemed most of the people shopping here were used to it.
"You should probably go to his office," one of his coworkers, a girl named Mia, spoke in a kindly way to him. She was probably half his age, but that didn't stop her from trying to hit on him.
"Right," he kept his answer short and clean. He didn't want to encourage that type of feeling from her. He didn't have the time or capacity for any kind of relationship. With both a heavy sigh and a feeling of certainty passing through him, Sasuke made his way to the back of the store. Outside, he could hear some sort of commotion, and a part of him was tempted to see what it was, but he was one foot in the grave with Mr. Usagi already. There was no reason to make it worse and lose a paycheck. If he hadn't screwed himself already.
Working at a grocery store was grunt work. At best, it would have been a D-rank mission back home. Something for children and genin to earn a paycheck and instill a sense of camaraderie and teamwork within them.
