Wow, this is seriously getting a lot more traffic than I thought it would. For my first story, it's making me feel pretty good about myself for making this. Anyways, this is finally starting instead of just having pure exposition. There still will be a bit of exposition but it still is the beginning of the story after all. This one is a little bit longer than the others only because I didn't want to leave it on a terrible cliffhanger because I personally hate that. And why would anyone write something they hate reading? Anyways, I hope this chapter sets well with anyone reading.

The earth began to shake this morning at a consistent rate as screams bellowed throughout the city. This, however, was not the result of tectonic plates shifting. Izuku knew better than this, the shaking was off, it was at a similar pace to a person running. He looked towards the crowd gathered below the train tracks, they knew as well.

He turned to beckon his brother, now around the age of ten. He wasn't the height of the average ten year old though, he towered above most people as he was almost as tall as All Might! "C'mon Hellboy! We'll miss it!"

Hellboy was keeping behind Izuku in an oversize version of the middle school uniform. He also had to rip the sleeve off his right arm just to get it on due to what Izuku and him had named, "The Right Fist of Doom." after the strange events that followed his arrival and the time thereafter. He also, because of the Fist, couldn't properly button his shirt so most of the time he just wore a stretchy white T-shirt underneath his uniform so as to not get in trouble with the school staff. His tail also wasn't as much of an issue since more people had quirks involving tails than big fists, so the pants had fit pretty nicely, even though Hellboy preferred those a bit baggy too. Since he grew so much so quickly over time, Inko had gotten fed up with getting him fitted clothes every time he grew three sizes a year. He also had shaved off his horns down to stubs as well as some spikes on his fist after a lot of complaints of the Devil hanging around a bunch of kids.

Hellboy responded by catching up to Izuku and running at his side, "Alright, I'm comin'! Who do you think it'll be this time?"

Deku smiled, pulling out his journal that he labeled, "Hero Characteristics" as he was trying to figure out all about the heroes that were out and about so that when he became a hero he would be able to fight alongside them! "I don't know, but it sounds big! So I'd say someone with a lot of strength."

When they got to the crowd, the studious kid was stuck trying to get a good view, everyone was blocking his way! He turned to his brother, who already knew about his situation. It happened every time. "Don't worry, you'll see it." Hellboy consoled as he knelt down. Deku got on his shoulders and in just seconds, he was about ten feet in the air with a perfect view of what was to come.

A giant man with the head of a mole is looked like came crashing through on top of the train tracks. He bellowed in rage again, "JUST LEAVE ME ALONE! I WAS ONLY TRYING TO SNATCH A STUPID DAMN PURSE!"

Trailing behind was a hero by Kamui Woods, a hero whose body is able to turn into that of a tree and extend into branches at will! Whoa, this is intense! How is he going to take down a quirk of this magnitude? Deku exclaimed to himself. He began writing down possible solutions.

Hellboy perked up, "You better not be using my head as a desk, bro."

Deku knew Hellboy was joking, Hellboy has turned into a bit of a jokester as he's gotten more confident. And he has gotten confident, and for good reason according to Izuku. He's gone through some really crazy things over the years, gotten through attacks from what they both have discovered was something paranormal. Ghosts, goblins, yokai, you name it, Hellboy has fought and killed them. Deku didn't like that Hellboy killed them, but because of the nature of these creatures and the fact no laws are set in place prohibiting the killing of things like ghouls, there wasn't much he could do to protest his brother's actions. He never killed a regular criminal though, so that did bring Deku to ease a bit.

The criminal used on of the nearby electrical towers to stop. This prompted the tower to topple over towards the crowd. Hellboy got Deku on the ground as soon as possible, getting into a defensive stance towards the plummeting debris. Hellboy raised his arms, seeing the bent portion of the metal point towards him. He didn't have to do too much though, as someone else caught the tower piece in the center of the crowd.

Izuku looked at the crowd, immediately identifying the hero, "Death Arms!"

Kamui Woods began yelling at the criminal on the tracks. Neither of the could hear the hero through the commotion in front of them, the crowd was getting loud now. Kamui was a very popular hero and was fairly new too. He screamed, which was still barely audible, "Lacquered Chains Prison!" as his arm extended to the villain.

Deku was gasping, "That's one of his special moves!"

He didn't get to use it though, as someone else had just dealt with the criminal. A woman the size of a mountain came crashing through, kicking the villain off the tracks and into the pavement below. She proceeded to pick up part of the criminal as Kamui was yelling in frustration. She began flaunting the part of her body most of the crowd, which was made of a lot of men, could see.

Hellboy shook his head, "Hate attention seekers." he looked to his brother who had just closed his journal. "You get what you need?"

Izuku nodded as Hellboy picked his brother up with his softer hand, "Good, because if we don't get movin', we'll be late for class!" Hellboy proceeded to run at full speed towards the school, which was about as fast as a car.

In Class

Deku and Hellboy got to class right before the bell rang. They had the same class, as they did every year, which helped with timing because of Hellboy's size and authority, he's always able to get people out of his way when he needs to.

The teacher got done with his lessons, and began with the talk about high schools. It was really a bore until he actually got to the big school. "It seems only three people in the school have tried entering into the UA Hero Academy."

He was cut off by Bakugou, "Yeah, and I'm going to be the one to blow the socks off of everyone. Everyone else is just a bunch of side characters!"

A random kid spoke up, "Hey man, that's uncalled for!"

"Oh yeah? And who's going to stop me from saying that, huh?" He laughed menacingly.

That's when the teacher spoke up, "The Midoriya brothers are also looking join the UA Hero Academy."

Katsuki turned to Deku and Hellboy, who were sitting side by side. Izuku had his head lowered, terrified by his old friend's livid expression. Hellboy just looked at him with a bored expression on his face.

"What's that? Some bug thinks he's going to upstage me!" Bakugou looked to throw a jab at Deku with an explosive force, but was stopped by Hellboy's right hand. The explosion went in every direction but in his brother's.

The devil boy got up, towering over the blond. He bent the desk so as to have a clear way to the aggressor. He walked forward so that Bakugou had to look straight upwards to look him in the face. "If we have a problem here pal, we can settle this. I'll warn ya, you might not be able to sign up to any high school afterwards."

His brother stepped in, "Hellboy, don't do anything like that! He didn't mean it!"

Hellboy just shook his head, it happened every time Bakugou got angry. Hellboy would stop him, a fight would almost happen and his brother would stop it immediately. You'll get yours Bakugou. And I'll be the one to kick your ass. Hellboy warned in his head before moving back to his seat, which he barely fit in anyways, and bending it back to where he could use it.

The rest of class wasn't as exciting. The regular lessons ensued and the end of the day came rolling by in no time. Hellboy beckoned towards his older brother, "Hey, I gotta leave early, the horns are getting a bit long for my tastes and I gotta get a new sander for it."

Izuku nodded, "Sure, go on ahead." Izuku always wondered if it hurt when he sanded down his horns and spikes. He knew it definitely hurt the sander, those horns are so strong that they break the machines after a month of using. Luckily, the depot store always gave him a discount given his situation, so it helped with money at home. "I need to clear my head anyways, think things for a bit. Can you tell Mom that I'll be home a bit later than usual."

"Yeah, no problem. See you then." He left the classroom.

After a hours of being home, Hellboy finally finished sanding his horns. He did it outside on the porch as to not get anything in the carpet and on the furniture. Inko always hated when that happened. He kept a bucket of the shavings so when he was done he could dump them out in the dumpster of the apartments. The newly groomed devil got up from his position of sitting to go inside.

He took his school uniform off at this point and was wearing his black tanktop and his black skinny jeans. He didn't wear his shoes so his hooves were showing on the ends of his feet. He was comfortable like this, letting all of his features that set him apart from everyone else, even those with quirks be free.

Inko, who was now bigger through the stress of raising two boys by herself, was obviously getting worried, and Hellboy was too a little bit. Even if he is out late, he usually isn't this late. He set the bucket outside and turned back to his mom, grabbing his cellphone. "I'll go get him, Ma. Stop worrying so much."

Inko turned to her son, who was as much of a son as her flesh and blood. "I just get so worried about him being alone out there! That he's going to be left behind. He still wants to be a hero and even signed up for the academy!" she blew her nose. "I know you also joined but we both know what you are, what you're capable of. It makes sense for you to be a hero, but little Izuku?"

He understood what she meant, but he also saw what she didn't in him. He didn't blame her for it, and he knew she didn't do it out of spite or anything mean, but because she was just concerned for him. Hellboy hugged her with his soft hand, "Me and him are a team Ma, I've got his back and he's got mine. Nothing can take us down."

He rose and turned to the door, "Now, I've gotta go get my partner and make sure he isn't doing anything stupid. So stop your worrying, Ma."

He closed the door, hoping that would put his mother's mind at ease, though he knew better that it wouldn't until she saw her son in the flesh.

Hellboy was jumping from rooftop to rooftop, peering over the streets for a sign of his short, green-haired brother. He jumped all around the city, but was stopped when he heard an explosion in the distance. "God, don't tell me." He started towards the explosions, which we going off pretty consistently. After a couple minutes and seeing the smoke rising, his worst fear had come to light.

It wasn't a monster, but it sure fit the bill. Some guy that seemed to be made from sewer sludge was in the middle of the street, yelling at the crowd on his right to get back as fire spread all around him. No one noticed Hellboy because of this commotion, which he was glad for. He looked in the crowd, and he saw his brother, with a face of dread on his face. Hellboy noticed him looking at something in the villain, so he switched his attention to the villain.

"Not you too!" He saw the head of a familiar blond, one that he had just fought with earlier today. At least that explains the explosions, the fire and why the heroes haven't dealt with him yet.

He looked towards the crowd, looking for his brother who moved again. Hellboy searched the back of the crowd, hoping he moved away from the situation when he saw someone familiar. He couldn't quite put his finger on it, but…

A scream, from a voice he knew! Hellboy looked to his left, the a boy throwing his yellow backpack at the villain, tears in his eyes and an expression of determination. The backpack hit the villain in the eye, making him recoil and scream in pain. Deku began scraping at the villain to no avail, the villain just got angry.

Hellboy yelled so everyone could hear him, "I'VE HAD ABOUT ENOUGH OF THIS SHIT!" He launched himself from the roof and onto the pavement, breaking it to pieces with his Right Fist of Doom. All eyes were on him now, he didn't care. His eyes, the eyes with the fire in them, that burned his enemies' confidence, were right on the villain, the villain with an old friend and that about had his family. He rose, showing off his full height, his muscles that showed through his tanktop. He peered into the villain, and walked towards him, right through the fire, not that it hurt him. With his shirt burning and him closing in, the villain could feel the next step.

"No! Stay back! Or I will-"

"What? You'll kill them? Then that means I get to hurt you. Kill me? You can try, but you'll be shit out of luck if you think you could hurt me." Hellboy went for the mouth, with his Right Fist of Doom he crushed his mouth, cracking the teeth with his sheer grip alone.

The sludge villain panicked, dropping Bakugou and Izuku. His eyes were no longer of anger, of hunger, but pure fear. A submissiveness that made his entire body slump into the ground. That wasn't enough, he'd seen monsters like him before, if he let him go he would just do this again. No, Hellboy knew, he had to hurt him regardless. He crushed his teeth, making the villain recoil even more than the backpack to the eye, he couldn't think, just scream.

Hellboy only stopped his onslaught when he heard a laugh. A laugh so powerful and one that he recognized from a person he met long ago. He turned to find a man, standing just a but taller than he, smiling on him, a man with golden blond hair that stood as tall as his reputation. All Might stood in front of the devil man, putting a hand on his shoulder.

With a booming voice, All Might told him, "Okay now, lad, the heroes can take it from here!"

Hellboy left the villain, he went to his brother's side who was being scolded. When Hellboy walked over, however, the heroes stopped. He put a hand on his brother's shoulder, "You've got guts, that's what I like about you most. Good job out there, bro."

After the situation was dealt with, the heroes tried belittling Izuku further, but every time they tried, Hellboy would brush them off saying, "At least he did something. What did you do?"

The heroes moved on to Hellboy, who some were too scared to belittle, but Death Arms, the hero from the morning, wasn't afraid to scold the towering devil. "You were way to brutal with him! There was no need to break his mouth, now he can't ever speak again!"

After that, Hellboy was praised for how strong he was. The flattery was nice, but not his cup of tea, so he waved them off and walked with his brother home. Where hopefully they could get some peace and quiet after a very long day.

On their walk home, the brothers were met with an angry Katsuki. He ran to them, and began yelling right out of the gate, "I DIDN'T NEED YOUR HELP YOU DAMN QUIRKLESS DORK! AND YOU, DEVIL BOY!"

"It's Hellboy, dumbass."

"WHATEVER! I DIDN'T NEED YOUR HELP EITHER, SO STAY OUT OF MY WAY!"

As he left, the brothers looked at each other and laughed. Some things never change, no matter what you do.

The boys had yet another meeting with someone else, the same golden blond Hellboy met today.

"Young Midoriya! I-" He stopped when he saw the red man.

"Long time no see, eh?" Hellboy greeted.

All Might awkwardly responded, "Ah, so you do remember from back then."

Izuku looked to his brother, dumbfounded. "Wait, you know-?"

"Not really. We can talk about that later." he looked to the hero, "You wanted to talk with him or what?"

All Might struggled, he couldn't hold his form anymore. So much stress accumulated on this form that he had to break it. He coughed, blood gushing out from his mouth.

Hellboy leaned against the wall, not at all fazed by the now emaciated man standing where the number one hero stood. Izuku, however, jumped as a bit of color drained from his face.

"Right, well, I guess it can't be helped." he took a look at Hellboy, "Could you, maybe give me and young Midoriya some space to talk?"

"Whatever you've got to say to my brother you can say to me, old man."

"Brother?" All Might looked to Izuku, slightly puzzled, but continued. "I guess that's fine, if you're brothers."

He sighed, "Izuku, you know how I told you before, about how a quirkless cannot be a hero?"

Izuku's head lowered, remembering the conversation they had earlier.

"After the events of today, I think you may have just proved me wrong. You showed me that despite the adversaries you faced, you still faced them. You still put your own life at risk for another's."

Izuku's head perked up, surprised by the sudden change of narrative.

"You reminded me today what it takes to be a hero, that all you need is the spirit and the courage to save another. I lost that meaning long ago. Which is why I want to make an offer with you."

Tears started to swell in his eyes, Izuku couldn't handle what he thought was going on. It didn't seem possible, and yet it was happening!

"I want you to inherit my quirk. One for All, is a quirk that is passed down from generation to generation, one that gives its user an ultimate power. So please, accept this offer, young Midoriya."

At this point Izuku was on the ground in tears, tugging at his shirt. Hellboy saw how much this meant to him, his number one hero, his idol, giving him the power he once envied. It was all too good to be true. Hellboy only had questions but decided not to say anything, he didn't want to ruin this for his brother. This was his moment, one he deserved after such a long time of torment from others with quirks. The bullying from Katsuki, the doubt of their mom, the shadow of Hellboy himself. He finally had an opportunity to make a light for himself, and he could only smile. Smile at the happiness he knew his brother felt after such a long, dreadful day.
