It was a typical day for the quirkless teen known as Izuku Midoriya, running away from his bully's as fast as his legs could carry him. He didn't understand why they always picked on him: Only him. All he ever did was say that he wanted to be a hero in class. Sure, they made fun of him for his dreams, that didn't mean they also had to beat him. It was even worse as Katsuki was the one picking on him. Katsuki and Izuku were once friends, but that all changed when they were age four. Bakugou got a marvelous quirk while Izuku was left quirkless. Katsuki became powerful while Izuku became his punching bag, a 'Deku' as the mean teen would say: An insult to his name, meaning 'The one who can't do anything'.

After running for so long, Izuku found himself in an alleyway. His legs burned and he had lost his bearings during his attempted escape, his bullies appeared to have vanished, so that was good. Or so he thought, "Well Deku, I'll admit your fast on your feet, but play time's over," Katsuki said in a menacing voice. His other two allies had also caught up by now. They seemed out of breath but were still ready for a beat down. Izuku backed against the wall, his body froze, too scared to defend himself. Katsuki grabbed Deku by the collar and shoved him against the wall.

"So, little Deku still thinks he can be a hero huh," Bakugou said as volcanic explosions formed on his free hand.

"I take back what I said Kacch-" Izuku was interrupted by a punch to the face.

"I said never call me that." Bakugou spat at the green-haired freak.

"I'm sorry," Deku replied, tears forming in his eyes.

"Jeez, Bakugou do we really have to do this," one of his friends asked, a little confused as to why they had to bully this quirkless all the time – "there's no fun in bullying someone like—".

"Quit it, you extra," Bakugou yelled back, "We have to teach Deku here a lesson." On cue, Bakugou sent his right knee flying into Deku's stomach. Izuku coughed as his body dropped to the floor with a thud.

The group ganged up on him, striking him anywhere they could. Deku was unable to utilize any means to defend himself, he just laid there being kicked. They, unfortunately, had quirks that could cause some serious damage, whilst he possessed nothing.

He was just a punching bag for the strong. Deku refused to be a mere punching bag his whole life. Deku wanted to be strong: All Might levels of strong… But there was absolutely no possible way that he could. Without a quirk, the ground was where Deku belonged. It was useless to resist. Modern society deemed him useless for anything. No matter what he did or how hard he desperately tried; a quirkless, useless, fragile person like him would always be society's punching bag. Why even bother at life at this point. Perhaps it'd be best if he just died. The only person who would care is his mother. There was his dad, but he's always overseas working, never there when his son dearly needed him. Then again, who would sincerely care for a pathetic, quirkless, unimportant person… Even if they are your son?

Despite being spaced out for a bit, Deku's mind had been brought back to reality by a small explosion to the face. His body was now covered in bruises and ached. Bakugou was towering over him, making sure that he stayed down.

"Just give it up Deku. All you will ever be in life is a pebble and no matter-"

"Excuse me." A figure interrupted Bakugou as he was talking down to Deku. The 3 bullies turned to face the voice that had interrupted Bakugou. He was tall, muscular and had dark black hair. The anonymous stranger also wore a casual jogging outfit.

"Listen, man, I don't know who you are but how about you run if you know what's good for you," Bakugou said in a confident tone. However, the unknown stranger did something that surprised all of them: He laughed.

After what felt like forever, his hearty laugh ended. The man continued, "It's common for the weak to think they are strong."

The group of boys was shocked and confused at what the man said. Did this unknown extra call Bakugou weak? How was that even possible? Bakugou has an extraordinary quirk, not to mention his insane intellect. How could anyone call him weak? There was only one emotion that Bakugou was feeling right now: Pure, unfiltered, blood-boiling RAGE.

"You piece of shit! I'll show you who's a weakling. Let's fight it out right now." Bakugou stopped standing over Deku and faced his new opponent, hands ready to throw fireballs.

The man put both of his hands up saying, "Sorry kid I don't fight anymore."

That sentence made Bakugou's anger turn from a burning fire, into a world-ending volcanic eruption. This fucker who doesn't fight claims that he was weak?! The teen launched himself at the intruder, using his quirk, Bakugou quickly closed the distance between them. Bakugou was about to throw a left punch but soon found his back against the hard concrete floor. He felt no attack of any kind hit him, so how did he fall on the ground? Getting up, Bakugou threw a right, only to fall face first on the ground.

' What the hell is going on? ' Bakugou asked himself. This was the first time in his life that the blond had no idea what was happening.

"I told you, you're weak," the man stated with calm composure.

However, Bakugou wasn't the only one attacking. Behind him, the boy with sharp teeth attempted to launch a bite at him. His attempt failed when the man put two fingers on one of his teeth and yanked. The boy screamed in pain as blood poured from his mouth. The long finger boy watched in terror as his friends were beaten with little effort.

"You bastard… We'll call the cops on you!" The kid threatened, trying his best to act brave.

"Oh, and what will you tell them?" The stranger asked, "Because, from the looks of it, it seems that you attacked both this boy and me first. Also, two of you tried to use your quirks on me, which is illegal… So, let me ask you again, how are the police going to respond to that?"

Everyone stood in silent shock. In only a few minutes the man had utterly defeated them.

"Amazing…" was all Midoriya could form.

"Why you-!"

"Drop it!" Bakugou commanded. The two co-bullies turned their heads toward him as the blond was getting back up.

"As much I hate this bastard, he's right," Bakugou said. He went back to his cronies before saying "You just got lucky you bastard."

The man turned to the young teen, telling him, "In a fight, there is no such thing as luck. Remember that sparky-fist." Those words just made Bakugou grow further into a rage.

To everyone's surprise, Katsuki simply replied with "Fuck you." Before walking away with his goons.

The man turned to face Izuku. Izuku, on the other hand, was still shocked by the fact that Kacchan had been beaten.

"Hey kid," Izuku turned his head to face his savior, "Are you alright?" Izuku had a black eye and brushes all across his body, luckily that was all, no broken bones.

"Ah, yes thank you, sir," Midoriya gratefully thanked as he bowed his head down.

"What's your name kid?"

"Midoriya Izuku s-sir!" He stuttered, still a little banged up from the beating.

"Well then Izuku, there's no need to thank me."

The man was about to leave when Midoriya cried, "Wait, I need to ask you something." The man turned back to face the kid. "How were you able to do that?" Midoriya asked.

"You have to be more specific." The man said.

"When Kacchan tried to attack you, you placed your palm right against his chin. That was what caused him to slip right?"

"Yeah, it was," the man was amazed by this boy. When he did that move, his hand had moved faster than the human eye could track, yet this boy saw it.

"That is correct. I reversed the speed at which the boy was going. Remember this kid, the faster someone goes, the more fragile they become." The man said.

"Thanks, I'll keep that mind," Izuku took out a notebook and pen and started to write things down.

"One more thing, that kick you did to knock Kacchan down. I saw you specifically aim at his foot, is there a reason why?"

"Yes, there is. Footwork is very important in a battle, it controls your balance and if done well, can add power to your punches."

"Thank you, sir, I will take note of that," Izuku said. "If that is true,"

"If?"

"Then that could apply to a hero like Miruko who uses her legs to attack. Or someone like Seal who often bounces around in a fight." The boy kept on mumbling on and on about what quirks could work best with different kinds of footwork and potential ways to counter said footwork. The man was impressed. He just said one sentence about footwork and the boy was written pages full of info. The man had a long experience in fighting, with many scars hiding in his clothing. Yet this kid had something he had never seen before, an unknown potential that was waiting to be released.

"I was wondering Midoriya, why were those kids picking on you?" the man asked. The boy looked down on the ground, not wanting to answer that question. "Your quirkless aren't you?" The boy continued to look down on the ground. "That makes sense, quirkless people are often treated like trash," the man said. He saw that the kid's spirits were already being lowered. It seemed like he had stepped on a mental landmine. The man hadn't seen many quirkless people in his lifetime. Well, there was one person he knew who once was quirkless, but he didn't like looking back on bad memories.

"Sir, can I ask you a question?" Izuku asked.

"Sure," the man replied.

"Can someone as weak as I become as strong as you?" Izuku asked, desperation leaking through his eyes, along with tears. The man knew that his answer could have an impact on this boy's life.

"Honesty," the man said, "I can't answer that question."

"Oh," Izuku said as he lowered his head.

"But you can," The man said.

"What?" Midoriya asked in confusion, his words seemed contradictory.

"If you want to get on my level, then you have to work hard to get there. However, I don't mean just push-ups and sit-ups. I mean the work that would make Hell sympathize with you. I'm talking about running when your legs are broken and bruised. Use a punching bag when your wrists and hands are broken. And when your hands are beyond damaged, use your teeth to pick up weights. That's what I mean." Midoriya was shocked by the man's words. That kind of training could kill someone, and he's expected to do that?

"Well that's just my answer," the man said. He was about to leave we the boy asked him a question that would change his life forever.

"PLEASE TEACH ME!" Izuku yelled out. The man turned around to face the boy.

"What did you just say?" he asked.

"Can you please teach me?" Izuku asked. The man had never expected to hear those words from the timid youngster. The man walked up to Izuku only for him to say one word.

"No." The man firmly stated. The world shattered for Izuku.

"What?" he mumbled.

"I can't train you." The man said.

"Why not?" Izuku asked.

"First of all, you're a good kid. If I put you through the hellish training I just described, then you would probably die in the process." Izuku wheezed a little at the mention of death. "Secondly, if you did survive on some of the early training, you'd probably quit after the second week. Most sane people do. Finally, I'm not just going to help some random kid I just met. If you want me to train you, you are gonna have to prove to me that you can handle it." That was all the man had to say before he left the boy and continued on his jog.

Izuku was baffled. How was he supposed to prove himself? He had no quirk or any remarkable talent to speak of. So how could he prove himself to that man? That man was strong enough to pull teeth out with two fingers. What feat could impress a man like that? He could do some training to get a six-pack. No, that would require regular training. Nothing like what the man said. He needed to do something extraordinary.

Izuku was currently walking along a path that was new to him. Due to those bullies, he had lost his whereabouts and had to use street signs to navigate home. However, while walking along this new route, Izuku saw something weird. It was something that shouldn't be there. Something that shouldn't exist. But it gave Izuku a bright idea.

"This, this is perfect!" He cried to himself.

5 MONTHS LATER:

The man woke up later than most people. He had no job, so most of the time slept in late. It wasn't because he didn't want a job. In fact, no job wanted to hire him. The man didn't go to high school for "personal reasons." He also didn't have a job besides that. However, there was no way any company would hire him knowing he did those things. So, despite his constant job interviews, he always received the same response.

Rejected.

To be honest, he didn't need a job. In fact, as long as he was the only one who had access to his bank account then he should be perfectly fine financially for at least twenty years. But he didn't like to use that money. Especially because he earned it from his old job. He really didn't like his old job. It wasn't a good time in his life.

After getting up from a long nap, the man did what he usually did. Find breakfast, usually fish. It was an odd trait that the man inherited from his sensei. Plus, with a pretty famous fishing spot nearby, it was pretty cost-efficient. Grabbing his only fishing rod and putting on some clothes, the man went out to hunt his food. It wasn't a long walk, mainly because he lived in the woods. The "house" that he currently lives in was once a dojo but was long abandoned. It was strange, in some ways that old dojo reminded him of his Sensei's temple. However, there were way more differences than similarities.

The man had finally reached his usual spot after about 10 minutes of walking. After placing some bait on the hook, the man cast his line out to the pond and sat down, waiting for the fish to come. On his arm, there was something strange attached, it was a pair of weights. Not just on the arms, but the legs as well. At first, they looked normal. However, each of them weighed about one ton each. Meaning that the man was currently holding four tons of force and was walking around like it was normal. To put it in perspective, that was the weight of a hot-tub!

After a few minutes, the man was finally able to catch a fish. It wasn't very big, but it was good enough for a light breakfast. He made a small fire, he didn't have an oven at home, the man silently ate his breakfast. Since he had no utensils either, he just ate it with his bare hands. When he was finished, the man went back home. After a failed job interview, he decided that a good old fashion jog would help clear his mind.

Usually, he would just go around three cities, but today, he was going to jog the whole country of Japan. To most that would seem like an impossible task, but the man had seen and performed things, most people wouldn't even believe in. Something like this was nothing.

After running a few miles, the man encountered a surprisingly clean beach. This came off as a surprise, not because the beach was clean, but because it shouldn't be clean. He remembered a few months ago, there was heaps of garbage. Garbage that spread for miles. How in the world could such a mess be cleaned? The man slowly observed the beach. Besides a few pieces of trash, it was perfectly clean. The man did not remember any promotion for cleanup, so either a small group of people clean this up, or a single person. If it was the latter, who would do such a difficult task and why? Was it out of kindness or were they trying to prove something?

After a whole minute of observation, the man found the culprit of the cleanup. It was the kid he saved five months ago. His name was….. Izuku Midoriya. The man wasn't very good with names. The man also didn't expect this boy to accomplish something like this. When he last saw the boy, he was a scrawny twig. But now the boy was way different. Midoriya had gained a four pack, most likely because of all this trash he was hauling. Midoriya was probably working out as well to get more muscle. Basically, this kid wasn't the same as he was five months ago.

Midoriya was currently trying to move a truck that was stuck in the water. Despite his new strength, he couldn't move the vehicle a few inches. That was until the man picked up the truck and back tossed it into the pile of garbage behind him. Midoriya at first was surprised by both the man being here and the fact that the man threw a massive truck so easily.

"Sir, what are you doing here?" Midoriya asked.

"I was out doing a jog," the man replied. "Why did you do this?' asked the man.

"Well, remember when you said you'll only train me if I can prove myself," Midoriya said. The man was shocked.

"You're telling me that you cleaned this whole beach, just to prove a point," the man said. Izuku just nodded. The man sat down on the sand and for some peculiar reason, started to laugh. He laughed like a madman. He laughed so much that it even creeped Midoriya out. Eventually, he stopped and stood back up.

"Midoriya, do you have school tomorrow?" the man asked.

"Yes, sir," Midoriya responded.

"Alright, meet me by Jago park after school then," the man said as he started to leave.

"Why?" Midoriya asked.

"Why? I thought you wanted me to teach you?" The man asked with a cheeky grin, Midoriya's face grew from shocked to a simple smile.

"Alright Sensei," Midoriya said.

"I have a name you know," the man replied with a smile.

"I'm sorry. But what is your name?"

"It's Shinu Senshi," the man said.

"Alright, Senshi-Sensei!" Midoriya said, donning a proud look.

"Just call me Senshi," the man said.

Although Izuku didn't know it right now, this was the story of how he met the King of Fighting. Also, I probably didn't mention this earlier, but this is the prologue for how the World's Strongest Hero: Deku, came to be.
