Author's Note: Hey everyone, Fire Slash here and welcome to a brand new fic. I recently started watching MHA and I got to say, I'm loving it so far. Now, a few things before we start: first off, this is a story about Deku having the powers of the Marvel hero Black Bolt. I wanted to let you all know that if it wasn't obvious enough. Secondly, this is one of four Marvel/MHA fanfics I have planned, one of them even being a Villain Deku AU. Third, should Izuku get One for All in this fanfic on top of his regular powers? Let me know in the reviews. Finally, pairings. Tbh, a romance subplot always seems to be a staple of my fanfics and I want to do one with this fic, especially considering Izuku's state. I have no idea who I want Izuku to be with though, so I'm letting you guys pick the girl. Anyone you want to see specifically? Let me know in the reviews.

Now, with that out of the way, let's get to the story shall we? Review and enjoy :-).

0000

Society is cruel, a universal fact which never seems to change. Humans have always felt the need to judge one another, using another's shortcomings to justify their worth. They're willing to use anything, whether it be strength, appearance, wealth, or intellect to place themselves on a pedestal, all while they scoff at those who seemingly lack these 'grand' traits.

One can only imagine how the judgemental nature of society grew once humans began developing quirks. Quirks, innate superpowers eighty percent of the world's population are born with, became society's newest means of determining one's worth. If someone has a cool quirk, they'd be worshipped no matter how horrible of a person they were while those with 'lame' or 'useless' quirks were brushed off to the side.

Now, one's power didn't always make them respected. If they had no means to control their destructive power, they'd be treated like rabid animals needing to be put down. Sometimes, a random vigilante would do the honors. These people were below those with weaker quirks on a social level due to their unpredictability.

Finally, there were the people dubbed as 'quirkless.' Quirkless people make up twenty percent of the world. As the name implies, they have no abilities, their social power being miniscule. Whether it was better to be quirkless or have an unstable quirk is a topic still debated to this day.

For the first seven years of his life, Izuku Midoriya was classified as quirkless. While his classmates had developed their gifts while they were still in kindergarten, he never got his, causing him to be tormented relentlessly by his peers. His mother, worried about the fact his quirk has yet to manifest itself, ended up taking him to a local clinic where it was revealed he would be quirkless his entire life. This devastated Izuku. A kind boy, all he wanted was to be a hero, someone who uses their quirks to save others. The mighty hero All-Might being his idol, his desire to follow in his idol's footsteps was strong. Sadly, it seemed fate had other plans for the boy...or did it?

When Izuku reached the age of seven, his quirk finally manifested, and let's just say his life got much harder. Having developed slight superhuman strength and speed as well as enormous amount of superhuman endurance and flight, Izuku was ecstatic when he got his quirk, that is, until he opened his mouth. He was at home when he discovered his quirk. Running to his mother, he called out to her, only for all hell to break loose. Upon opening his mouth, an enormous shockwave escaped his lips, ripping his home in half. Though no one was harmed, the event managed to traumatize the boy for life. Not only was his power extremely unstable, if he were going to live with it, it meant he could no longer speak. For the next seven years of his life, the boy was forced to undergo intensive training to keep himself silent no matter the event. This included having to find a way to produce silent sneezes and coughs while also trying to find a way to avoid snoring. His endurance was pushed to his limits as well, for if he make any type of noise upon getting hurt, it could be catastrophic. To communicate, he was taught sign language. All of this was done in a laboratory designed to contain people who's quirks were unstable like his, a place where he spent most of his days. He even had to live there for a bit to master the art of silence.

Thankfully, him living in the laboratory was temporary. He was eventually allowed to rejoin society. Despite the doctors giving him the ok, Izuku's mother forced her son to not reveal his quirk to anyone. The last thing she wanted was a villain kidnapping her son and using his quirk to harm others. It also didn't help that his quirk seems to be getting stronger as he got older.

'Ugh, c'mon clock, hurry up!' Izuku thought to himself as he watched a clock. Today was a Saturday, the day before the weekend (in Japan at least. They don't have Saturdays off), and all he wanted to do was go home and research some quirks, a hobby he took quite seriously. Even though his power was unstable, his dream to be a hero has not died. He still had his other powers, so it wasn't like he had to rely on his 'quasar scream' to fight crime, the name his doctors gave the vocal part of his quirk due to the destructive power it held. It nearly destroyed the laboratory twice, a place capable of containing even All Might.

"All right, as you all know, you're all reaching the end of middle school," Izuku's teacher stated, seemingly finished with whatever it was he was talking about earlier. "Now's the time you all think about your futures. Eh, who am I kidding? All of you are planning on becoming heroes, correct?"

Upon saying that, most of the students began cheering in affirmation, some of them even displaying their quirks in a non-destructive manner.

"Hey teach, don't lump me into the same category as these crappy side characters," a boy with ash blonde hair scoffed. "I'm off to be the best damn hero you've ever seen."

"Hey man, don't do us dirty like that," one of Izuku's classmates muttered under his breath

"That's Katsuki Bakugo for ya," another student whispered to her comrade. "Rumor has it he's applying to U.A High school."

"Well, with an explosive quirk like his, he shouldn't have any trouble getting in," the student's comrade whispered back.

Katsuki Bakugo was a boy Izuku was familiar with, the two having practically grown up together. Katsuki possessed a powerful quirk, the ability to summon explosions from his palms, and an fiery attitude. With his power and attitude, Katsuki was someone Izuku respected. Sadly, the same can't be said about Katsuki's views of Izuku. To him, the boy was practically worthless due to his supposed lack of a quirk, not knowing the true power he held.

"Ah, right Katsuki, I forgot you were applying to U.A High School," the teacher stated, rubbing his head awkwardly. "You're surly aiming high."

"Damn right I am. I'll be the first student from this crappy school to get in and then I'll become a hero even bigger than All Might himself, mark my words!"

"Wait, isn't Izuku applying there as well?" A student asked, causing everyone to face the green haired boy in question. Noticing everyone's eyes on him, Izuku cringed, not liking the judgemental looks they were giving him. Eventually, after a few seconds of silence, everyone began laughing.

"Hah! That quirkless loser? He can't even speak. What makes him think he can get into U.A?"

'I can speak,' the boy thought to himself. He really hated how everyone judged his potential to become a hero due to them believing he lacked a quirk. It only motivated him to not show off his quirk even more, for he believed doing so would just promote more toxicity to be thrown his way. 'But everyone would get hurt if I did.' In the end, he shot his classmates an embarrassed look. It was all he could do at the moment.

"Deku…" Katsuki growled at his unofficial rival, causing the boy's eyes to widen in fear. As for why Katsuki called him Deku, well, Deku was a nickname the explosive boy gave Izuku, it being an arrangement of the letters of his name. The word meant 'useless,' which is why Katsuki latched onto the name.

For the rest of the class, Katsuki continued to shoot Izuku death stares, unnerving the boy. Eventually tired of the bully's actions, he decided to glance over his special notebook, one he used to keep track of all the quirks of current, retired, and upcoming heroes. If Izuku was going to become one in the future, he felt it was necessary to accumulate knowledge of those ahead of him. This way, he would be prepared to tackle anything that came his way.

It didn't take Izuku long to get caught up in his reading that he failed to take notice of the time. The seconds turned into minutes and the minutes into hours. Class was eventually dismissed, but Izuku didn't notice, that is, until Katsuki snagged his notebook.

"The fuck is this?" Katsuki asked out loud, making his victim nervously eye him as he had no idea what was going to happen. "Hm… hah, look at this! Little Deku wants to become a hero so badly he's even resorted to stalking heroes. How pathetic."

In the background, two boys snickered, them being followers of Katsuki despite the fact he simply saw them as extras. Izuku attempted to snatch his notebook, only for his bully to effortlessly duck out of the way. "Listen here Deku, you should just give up trying to be a hero. Not only are you quirkless, but you're fucking mute! How the hell can you help others if you can't even speak?"

Hearing this, Izuku secretly clenched his fist, unable to make eye contact with the other boy. He wanted to tell Katsuki that anyone could make a difference, no matter if they had unstable quirks or lacked one, but he couldn't, especially since his childhood friend turned bully never bothered picking up sign language. Only his mother had once he effectively became mute. However, the boy knew what Katsuki said held some truth. Him being unable to speak or use his quirk to its fullest power was one huge handicap. Despite this, he was still willing to do whatever it took to make these handicaps obsolete. It just meant he had to work twice as hard, something he was fine with doing as long as it showed results.

*BOOM!*

Looking up, Izuku noticed that Katsuki had activated his quirk to burn his notebook. He then simply tossed it out the window, much to Izuku's horror. Running towards the window, he began surveying the area, checking to see if he could find any traces of the book. Before he could find it though, Katsuki decided to open his mouth again.

"Like I said, no amount of research is going to cover up your flaws. Just give up, or, if you're really desperate in getting a quirk and voice, go jump off a building and hope you get those things in your next life."

Startled at what he just heard, Izuku began glaring at his bully, only to back down when he noticed several small explosions coming from his palm.

"Got something to say? Right, forgot you can't fucking speak. Whatever, I'm done here."

Watching Katsuki and his 'friends' leave, the boy released a loud breath of air from his nose, making sure not to open his mouth. No matter how much Izuku admired the boy, he couldn't help but get frustrated at him. For someone who wanted to become a hero, the boy sure had a rotten attitude.

0000

'Stupid Kacchan. If I did decide to jump, you'd be punished for instigating a suicide,' Izuku thought to himself as he searched his school's backfield for his notebook. Thankfully, it didn't take him long, for he ended up finding it in the school's artificial pond. Several fish were nibbling on it, but other than that and the burn marks Katsuki inflicted on it, the book was fine. 'Shoo, this isn't fish food.'

Rolling his eyes at the sequence of events which had occurred, the boy decided it was time to head home. Not wasting any time, the boy began walking home. Sure, he could fly home, but he didn't really want Katsuki finding out he had a quirk, at least, not yet. Once he was in U.A, he could pass off his flight, superhuman strength, and superhuman speed as his quirk being a late bloomer.

After some time, the boy began waking through a relatively dark tunnel, stepping on some sludge before he could leave the place. Giving it a questioning look, the boy didn't notice a large slime monster was sneaking up on him, until it was too late. Wrapping itself around him, the monster smiled as it tried infiltrating the boy's body.

"Ah, just my luck, a disguise." The creature said to himself as it kept trying to possess the boy. "And one of a harmless schoolboy no less. Looks like I can finally get rid of that pesky hero."

Hearing this, Izuku began thrashing around, using all of his superhuman strength to free himself, catching the villain off guard. "Huh, you're stronger than you look. Sadly, you're not strong enough."

Applying more pressure, the sludge monster began overpowering the boy, all while he frantically tried escaping. Unfortunately, with him running out of oxygen and not being able to grip the thing, Izuku was losing the battle, something he knew.

'Should I use my quirk?' The boy asked himself as he continued to struggle. 'On one hand, I can definitely blow this thing back, but what about our surroundings? If I even whisper, I'll destroy everything in a mile radius.'

His vision starting to black out, Izuku realised he was just going to have to take one for the team. There was no way he was going to hurt innocent civilians.

'Sorry mom, looks like I'm not coming home,' A single tear sliding down his cheek, he waited for his death…

"TEXAS SMASH!"

...only for it to never come as the creature was blown off him by a powerful gust of wind.

'All Might?' Izuku asked himself, managing to catch the faint outline of his hero before passing out, the lack of air having caught up to him.

0000

"Hey, hey kid, get up."

Silently opening his eyes, the boy noticed his hero was gently patting his cheek, trying to wake him up. Eyes widening in amazement, Izuku leaped upwards, surprised to be face to face with his hero.

"Thank goodness you're awake," the American hero stated, sighing in relief. "I would've hated it if anyone got hurt because of me."

Izuku simply continued to stare at his idol, wanting to ask him so much. Unfortunately, All Might seemed to be in a hurry.

"Well, now since that's over, you should go home and rest up. I got a villain I need to bring in. I've already prepared an autograph in that burned notebook of yours. Until then, Plus Ultra!"

The hero then flew off before Izuku could even spell out a word using sign language. Remembering what All Might told him, the boy checked his notebook and sure enough, All Might had indeed signed an empty page.

Smiling, Izuku looked up at the sky, a new sense of confidence flowing through him. Seeing his hero in action practically nullified what Katsuki told him today, instead motivating him to continue down his path at becoming a hero.

When he got home, the boy wasted no time in developing a training and studying regime. If he were going to get into U.A, he'd need to be prepared.

0000

Ten months after Izuku's encounter with his hero, the boy was now standing outside U.A High school's campus. Despite having prepared for the exam and knowing exactly what was on it, the boy was still nervous. After all, if he were being honest with himself, his quirks outside of his quaser scream were somewhat lackluster. There were many people who outclassed him in terms of strength and speed. Either way, the boy wasn't willing to back down. Doing so would be worse than failing. At least if he failed, he could say he gave it a shot.

"Get out of the fucking way Deku!"

Recognizing the voice, Izuku immediately stepped out of his bully's way, knowing full well that Katsuki was determined to pass U.A's entrance exam while also not liking the idea someone from his school was applying to the same high school. Thankfully, Katsuki didn't try anything, choosing to enter the building instead. After a few moments of staring at the building in awe, Izuku decided to enter as well, only to trip before he could even do so. Preparing to activate his flight, the boy was surprised when someone gently touched his shoulder, causing him to float. Looking to his right, he noticed a girl was keeping him afloat with what seemed to be some sort of telekinesis quirk. Or was it an anti-gravitation quirk? Eh, he'll have to find out later.

"And release." Upon saying that, the girl managed to release her hold on the boy, him landing safely on his feet. "Whew, it's a good thing I managed to catch you. Falling before the entrance exam would've been some serious bad luck."

Now, other than his own mother, his teachers, and the scientists who helped him control his quirk, Izuku has never officially spoken to a girl. As such, he began blushing in embarrassment, flashing her a quick 'thank you' smile.

"No problem. Well, good luck with the exam." And just like that, the girl seemingly left his life as quickly as she entered.

Deciding he wasted enough time making himself look like a bigger fool than he already was, the boy made his way inside the building.

"WELCOME TO TODAY'S LIVE PERFORMANCE! EVERYBODY SAY HEY!" Famous hero and U.A Entrance exam host Present Mic shouted, using his sound based quirk to louden his voice. Much to his surprise, no one replied. "Well, that's cool my listeners. I'm here to present the guidelines for your practical, ARE YOU READY!"

Again, he was meant with another awkward silence. "Wow, tough crowd. ANYWAYS, this is how the test will go! You will conduct a ten minute long city landscape maneuver! Within this city, there will be fake villains, each worth different amounts of points!" As he said this, the screen behind him started lighting up before revealing the three 'villains,' aka, three different types of training robots. "Use your quirks to disable them by any means necessary."

Hearing this explanation make Izuku smile. He was glad the concept of the test was easy. The main challenge would be getting to the robots before anyone else did.

"Oh, cheating or injuring others is strictly prohibited, so if you do any of these things., YOU WILL BE ELIMINATED! And trust me, we'll know if you do."

Katsuki scoffed before turning to a very grateful Izuku. "Guess you get to live for another day."

"ANY QUESTIONS!"

"Yes!" An formal looking individual with glasses said. "It was said there were no less than four varieties of fake villains on the handout. As the top hero academy in Japan, you should be ashamed of making such a careless error."

"Great point! There is a final villain, but they are worth zero points. I were you, I'd run if you encounter one. GOT IT!"

This time, he actually got a bit of cheers in response. "THEN BREAK A LEG EVERYONE! PLUS ULTRA!"

0000

After the briefing, Present Mic split all the test takers into four different groups and had them wait outside the mock city. Looking around, Izuku was glad to see Katsuki was nowhere to be found, meaning he was placed in a different group. Even though the wannabe U.A students weren't allowed to hurt one another, Izuku still didn't trust Katsuki to not do anything.

Shaking his head, the boy continued surveying his competition, only to stop upon noticing a particular brunette, the same one who saved him from humiliation. He still had yet to thank her, though he could only tell her by using sign language. Did she even know sign language? Probably not, but it didn't hurt to try anyways.

"Halt! Can't you see she's trying to relax herself?" Turning around, Izuku found himself face to face with the same kid who shamed the school for leaving out the fourth 'villain.' "She's taking this exam seriously. If you want to get in this school, I'd recommend you do the same."

"Uh, what are you waiting for?" Present Mic asked the students before Izuku could respond. "The exam started like two minutes ago. Villains aren't going to wait for you. GO!"

Turning his attention back towards the city gate, Izuku was surprised to see everyone had already entered the building after Present Mic's announcement. Flashing a meek smile at no one in particular, the boy shot forwards, entering the city. Upon doing so, he attempted to scout for robots, only to notice that a large chunk had already been taken out.

'It hasn't even been five minutes yet,' Izuku whined to himself as he continued to search for robots. Though it took a few seconds, the boy eventually managed to find a one pointer, who at the same time noticed the wannabe hero. Activating its weapons, the robot walked forwards all while Izuku walked backwards, fear enveloping his body. The robot was a lot bigger than he expected it would be.

'Dammit, why am I so pathetic? It's not going to kill me. C'mon, I need to destroy it…'

Unfortunately, before he could strengthen his nerves, the robot was blown to smithereens by a feminine looking blonde boy.

"Thanks for the assist," the boy mockingly said, mumbling something to himself before ditching.

"You have five minutes left," Present Mic shouted, using his quirk to broadcast this information throughout the city. Cursing himself, Izuku dashed forwards, doing his best to find any robots left untouched. Sadly, no matter where he looked, he couldn't find any he could destroy for points.

'This can't be how it ends,' the mute thought to himself, continuing his frantic search. It was then that something caught his attention. Using his superhuman hearing, he managed to pick up the sound of a robot walking. Excitement filled his body, until he realised something was up. The robot sounded a lot larger than any of the others. His suspicions were confirmed when an enormous robot walked into view a few seconds later, it being taller than most of the buildings in the city.

'So this is the zero pointer,' the boy mentally noted as the rest of his classmates began running away. Izuku desperately wanted to do the same, but his body refused to move, paralyzed with fear. If the one pointer was scary, than the zero pointer was outright terrifying.

For what seemed like hours, the boy continued to stare at the robot as it slowly made its way forwards, everyone else doing their best to flee the scene. Izuku could've sworn he saw the boy from earlier giving him a look of disapproval.

"H-help."

His left ear twitching, Izuku focused his attention towards the area where the noise was coming from. Much to his surprise, the girl who helped him earlier was trapped under some debris, and the robot seemed ready to step on her. Time suddenly appeared to slow down as Izuku's body shot forwards. He had no idea what he was doing, but he knew that the girl was in danger and in need of his help.

As he continued moving forwards, Izuku tried coming up with a plan. He knew for a fact he couldn't dent that thing even with his superhuman strength, so fighting it didn't seem like the best option. Glancing at the rubble, he thought about just removing it and pulling the girl to safety, but again, his speed wasn't high enough to do so before the robot's foot landed on the area. Analyzing the area further, he noticed that the robot's height was tall enough that if he unleashed a quasar scream targeting it at an upward angle, he wouldn't damage anything else.

'Am I really going to go through with this?' Izuku asked himself, really not wanting to have to resort to his quasar scream. However, it was either he use it or the girl and him gets crushed. Mentally groaning to himself, he continued running forwards until he was between the robot and the girl.

Noticing him, the girl was about to tell him to leave, leave and to forget about her, only to be interrupted by a spectacular display of power.

"Back off." Releasing an almost inaudible whisper, Izuku released an immense burst of energy, one which obliterated the robot before it could crush the two, leaving no trace of its existence behind.

With the robot down, Izuku turned towards the girl and shot her a worried expression.

"Are you ok?" He tried asking her in sign language, only for his question to be ignored as the girl stared at him with wide eyes. One whisper, that was all the boy needed to destroy something as grand as the zero pointer. Never before has she seen anything quite like it. The same could be said about the other test goers who wore the same expression as the girl. The formal boy in particular made sure his eyes never left the 'mute.'

"I've never seen such power before," He muttered in awe. "And to think he held onto such power throughout the entire exam, only using it to save one girl the rest of us had abandoned. He is a true hero. If this not an exam but an actual villain fight, would I have done the same? ...Of course I would've!"

"And time's up!" Present Mic shouted, though no one was really paying attention to him. All eyes were on the boy who annihilated the zero pointer with what seemed to be little effort. Speaking of the boy, despite being completely distraught about not having scored a single point, he knew if he found himself back in time to when the exam first started, he still would've saved the girl no doubt, despite not earning any points himself. To him, it was simply the right thing to do...
