AN: A favor for a friend.

1: Izuku Midoriya: Origins

"People are not born equal. That's the hard truth I learned at the age of four. But that was my first...and my last set back."

Izuku Midoriya

It all began in Keikei City in China with the news that a bio-luminescent baby was born. After that day, "exceptional" individuals began popping up all over the world. The cause at the time was unclear, but as time passed, the "exceptional" became the norm. Fantasy had become reality. Soon, eighty percent of the world's population consisted of Superhumans with special abilities.

The world turned to chaos, and a profession that everyone had only dreamed about entered the spotlight. Along with the exceptional abilities an explosion in the crime rate. While nations struggled to overhaul their legal systems, brave individuals took up the mantle of Heroes straight out of comic books, protecting the people from evildoers.

With public support, some quickly acquired the right to serve as heroes in an official capacity. Depending on their performance they had the potential to earn government pay as well as fame and glory.

This is not the story of someone born with special abilities...it's the story of a boy that would someday rise to become the world's greatest Hero, and his name was -

"I'm afraid there's no hope for him," the doctor said to the mother and her devastated son. The poor boy was wide eyed with disbelief, even for a four-year-old.

The mother looked horrified, "Please, Sir, there must be some kind of mistake!" She cried as her son dropped his toy figure. "All of the other children in his kindergarten class have started showing signs at least, but -!"

"Pardon me for asking, Mrs. Midoriya," the doctor said, holding up a hand gently, "But you're a fourth generation, aren't you?" He asked, "I mean as far Quirks go, am I right?"

Inko Midoriya nodded, "Well, yes," she said, raising her hand toward her child's toy, a figure of the world's number one Hero, which began to float up from the floor, and into her grasp, "I can move small objects toward me, and my husband can breath fire."

The doctor nodded, and pointed to a set of x-ray charts up on the board, "By his age, a child should manifest at least one of his parents' Quirks, or, in rare cases, a composite of the two." He said, sighing as he was about to dash the boy's hopes even further. "However, early Quirk research discovered one very important thing."

"And that is?" Inko inquired.

"It has to do with the presence, or absence of a secondary joint in the pinky toe," he said, pointing to the join in question, "Humans have no need for parts that they don't use, you see. And those without the joint represent the next stage of evolution." He turned around in his chair, sighing, "Little Izuku has two joints. It's becoming quite rare these days...but this means that Izuku has no Quirk abilities at all."

It was a long, quite walk home from the doctor's office as Inko led her son home. As soon as they reached their apartment the boy sat down in front of his computer, playing a news broadcast of his favorite hero, All Might.

"Mom," Izuku said, his eyes glued to the screen, "No matter what, he'll always come to save you with a smile."

Inko's shoulders began to shake with sobs.

The boy turned to her with tears overflowing from his eyes, "A cool superhero like that," he said, pointing to the screen, "That's what I wanna be!"

It was too much. Inko broke down and hugged her son tightly, sobs wracking her chest, "I'm sorry, Izuku," she sobbed, "I'm so sorry!"

{勇者}

"What do you mean adoption!?" Izuku came awake to an angered voice, "This is our son we're talking about! Not some lost puppy!"

"Mama?" The boy rubbed his eyes, and sat up.

"Now you listen here, Hiashi Midoriya, I don't care if he doesn't have a Quirk! He is my son, and that's all that matters!" She shouted as the little boy moved toward his door sleepily. On the other side was his mother, phone in hand, looking absolutely furious, "What do you mean he was supposed to have both our...you bastard! You just wanted a child with a strong Quirk, didn't you?!" Now Izuku was wide awake. He never heard his mother using such language unless she meant business.

"Now, darling, you know it wasn't only because of that, but - " That was his father's voice he was hearing on the phone.

"I told you, I don't care," Inko snapped angrily, "You have no place in this house anymore, Hiashi, so don't even think about showing your face to me or my son ever again! Do you hear me! EVER!" She slammed the phone down onto the receiver.

"Mama?" Inko gave a tiny yelp as she heard an equally tiny voice as she turned and found her son standing not two feet from her, looking up with tears in his eyes once again.

"Oh, honey, I - "

"Daddy doesn't want me anymore." He said, no questions in his voice. Inko bit her lip. Izuku had always been a smart boy, far smarter than most children his age, so she knew that he would be quick to figure things out...she just hoped that she could hide them from him a little longer.

Inko knelt down and wrapped her son in her arms, "Sweetie, listen to me," she said, "No matter what happens, Quirk or no Quirk, you're my baby." She began stroking his hair, "No matter what happens from this point, that will never change."

(10 Years Later - Izuku Midoriya Age 14)

"This is not what I imagined the finished product to be," said a man that was covered in severed hands as he gazed into the cage that held a...creature of monstrous proportions. "I had thought you had a different design in mind for the Nomus?"

Beside him, a man, his face covered in a medical mask, and dark glasses, chuckled, "Oh, this isn't a Nomu, my boy, this is something I came up with on a whim to raise a little hell, if you know what I mean?"

The man looked at him, "Oh, really?" He asked, "Do tell."

The "doctor" smiled as he wrapped the bars of the cage with his cane, causing the creature to stir, and lunge, six arms reaching through the ten inch steel bars, "You see, this little fellow is meant to be...an announcement I should like to say," he said as the mandibles snapped at him, revealing four large fangs on the outer mouth, and a secondary set in the inner mouth, "It's not as durable as your Nomus are going to be, but this fellow is the first of many that will self replicate once he's unleashed. As long as there is one, there will be more to come."

"Oh, I like where this is going," his friend smiled, "So, in terms of video games, this thing is a low level creature, yet it has great strength, and can multiply itself...but how is that done, exactly?"

"Through a bite," the doctor laughed, "You see how he's trying to get his head through the bars?" He pointed at the beast, which was trying its best to squeeze its massive head through the bars of its cage, "I've programmed him with the strong instinct to infect as many people as possible so that his species can survive. The venom of this creature would be fatal to most, but having engineered it differently, he has two different types. If he perceives someone to be weak, he'll infect them, and make them an easy turn, the venom only taking...oh, say fifteen, or twenty minutes to take effect, give or take. And then, for the next twenty-four hours, the infected is writhing in absolute agony!" He said gleefully as his friend laughed, "Isn't it wonderful?!"

"Indeed!" The hand-covered man laughed, scratching at his neck, "And the other venom?"

"A deadly cocktail of black widow, brown recluse and wolf spider," the doctor chuckled, "If push comes to shove, this big, beautiful beast will abandon his need to infect, and switch over to the secondary venom sacks, and go in for the kill! I doubt even All Might would be immune to such a deadly toxin!"

"Would it kill him?!"

"Doubtful," the doctor sighed in disappointment, "But, I can assure that anyone less than All Might would die a most agonizing death at the toxin's mercy." He said, "If the widow and wolf spider venom combo didn't kill them first, then the bacteria in the recluse venom surely would after rotting their bodies down to the point that they would appear as lepers!"

"Nice," the man said, smiling himself, "And here I thought this thing was more of a goblin, but he sounds more like a high level ogre to me now." He looked at the doctor, "When will he be ready to release?"

The doctor smiled, holding up a remote control device, "With your permission, Young Master Shigaraki?"

"You do the honors, Doctor," Shigaraki smiled, removing the hand that covered his face.

The doctor pressed the trigger button as the cage opened up beneath the beast and dropped the creature into the sewers.

Izuku was having one of his normal days of misery as he trudged home from school, a burnt notebook in hand, thinking back on that day so long ago when his world had come crashing down. But the young man that he had become was determined to achieve his dream of becoming a hero. Whether or not he had a Quirk or not.

His disappointment had only lasted for the one day because of the words said to him by his mother. [That's not what I wanted to hear,] he sighed in thought as he thumbed through his notebook, the pages consisting of notes on his classmates and their Quirks; on how they worked, and how to counter them.

[What I wanted to hear was that I could become a hero even without powers,] he thought as he came out from under the overpass that was his usual route home, [But that's when I stopped caring about what anyone says!] He growled, grinding his teeth, and raising his chin, [To keep my chin up and keep moving forward, no matter what!]

Behind him, a manhole cover began to quiver and rise as six red eyes glared from beneath.

A large shadow loomed over Izuku while he was reading, causing the boy to turn, and the boy froze. Standing before him was a massive, hulking creature. It stood well over eight feet tall, with six bulging arms tipped with three clawed fingers. The head was a grotesque mass of grey fuzzy hair, not unlike a spider, sporting six gleaming red eyes on an elongated skull two feet long, with gnashing, snapping teeth inside a mandible like jaw.

Izuku's legs trembled as he stumbled back from the creature, scrabbling away from it. [A villain?] He thought, trying to think of anyone that had such a monstrous appearance, coming up with a blank as his flight instincts took over, and the boy bolted. [No, a villain would've had me already! That thing's gotta be some kind of mutant!] He thought as the beast lumbered after him, surprising him with its speed.

It spat a line of webbing at him, narrowly missing him as he ran down the streets to get away from it. It bounded after him, using its webs to swing into the air and fly after him using the strong threads.

The creature's shadow passed over him again, [It's gonna get me!] He panicked, [Think, Izuku, think! Wha'd'ya know about spiders?!] He Thought frantically as he ducked down into a narrow alley. The Man-Spider lumbered after him, crashing into the walls of the alley, unable to fit due to its enormous size, reaching for him with three of its arms.

[Spiders are...sound sensitive!] The boy thought as he crashed into a line of garbage cans, causing a large amount of noise, which the Man-Spider didn't like at all if the way it was clutching at its head was any clue. [Common household chemicals are enough to kill most spiders!] He thought looking back at the monster as it crawled along the walls of the alley, fitting through just barely as its back grazed the opposite wall. "And the don't like strong smells!" He yelled, picking up and flinging a smell bag of garbage at the beast. It shredded it with its claws, showing the alleyway with the noxious contents.

The creature roared in anger as the smells assaulted its senses. Izuku laughed as he came out of the alley's opposite end and scrambled onto the streets, "Hero!" He shouted, seeing that there were people around, "We need a Hero over here, now!"

A police officer heard him and came running toward him, "Hey, kid, what's - ?!"

A monstrous roar sounded from the alley as the mutant crashed through the brick walls angrily, its rage filled eyes trained on the boy. "Ah, nuts!"

"Holy shit!" The officer yelped, aiming his gun at the beast, "Run for it kid!"

Izuku did not need to be told twice as he bolted with the crowd as they say the creature. Gunshots erupted as the policeman opened up, but the bullets didn't seem to do any damage, and was ignored while the creature took to the air again, searching for its prey. Izuku saw it leaping on its webs, and shivered as he tried to get away, "No, no, no, no!" He cried as the beast loomed over him again, and felt the impact of the web against his backpack, "Dammit!" He slipped his arms out of the straps and dropped back to the ground, only to hear the sound of large feet striking the asphalt.

Four arms grasped him from behind as he was lifted from the ground once more. He turned his head, met with the eyes of his attacker once more. "Oh, God, please! Not like this!" He shouted as the monster clamped down on his shoulder with its teeth. Searing, mind-numbing pain erupted in his left shoulder as the mandibles went to work, chewing his skin and muscle tissue to nothing as the venom sacks emptied into him. It was how spiders fed. Their venom broke down what ever poor creature they attacked, and turned them into mush so they could drink the fluids from them.

"GET THE FUCK OFF'A HIM YA FREAK!" Roared an angry voice. A voice that Izuku knew all too well.

"Kacchan!" Izuku yelled as he saw his friend literally rocketing toward him with his Quirk blasting from his hands.

"DIE YA OVERGROWN BUG!" Katsuki Bakugo roared as he blasted the beast in the face with his Quirk; Explosion. Izuku felt the burn as his captor was struck with the full force of his Quirk, forcing it to release him. The burning sensation in his shoulder began to spread through his body as Katsuki bent to haul him up.

"Get off your ass, Deku, we gotta go!" The boy roared as he tried to move them away.

"Leave me!" Izuku howled, pain wracking his body, "It bit me, Kacchan! I can feel the venom!"

Katsuki was torn. He wanted to get Deku out of harms way, but he also wanted to turn around and blast the monster to prove himself. A student taking on a mutant like this one was sure to get into any Hero School they wanted. Without taking exams.

All that changed, however, when the monster roared angrily, and turned its eyes on them. Unharmed.

"Okay, no time to mope, move your ass, Deku!" Katsuki roared, hauling the smaller boy over his shoulder, and taking off.

Izuku, his vision getting blurry from the venom coursing through his body, saw with growing horror that the monster was still coming, slowly, but still coming for them. [Me,] the boy realized, [It only wants me...] He struggled slightly on Katsuki's shoulder and rolled off of him, plopping to the ground, and attempting to stand.

"THE HELL'RE YA DOING?!" Katsuki roared.

Izuku looked back at him with a sad smile, "You were right, I'm useless as a Hero without a Quirk," he said, "But at least I can save a few lives. This thing only wants me, so just get out of here, and find a Hero to take this thing down, Kacchan!"

Katsuki Bakugo couldn't believe his ears. Weak little Deku, the Quirkless loser, was acting like a Hero!

The mutant grabbed him up again, and bit into his right shoulder this time as Izuku's body went limp. "DEKU!"

"TEXAS," came a great roar from above them, "SMASH!"

A huge force of pure, raw power hurtled down from above as a large man, almost as big as the mutant, crashed into the creature, forcing it to release Izuku again. As the boy fell, the man caught him in his large, powerful arms. "Fear not, young man," he said, with a smile ever present on his face, "FOR I, ALL MIGHT, AM HERE!"

{勇者}

Izuku didn't know what happened to him after the mutant bit him a second time, but waking up he found himself in a hospital bed, and, remarkably, alive.

He looked around the room, wondering what had happened, but found no one around to answer his questions. But...he could hear...he could hear someone on the other side of the door speaking in hushed tones...to his mother!

"What do you mean that his body's changing?!" Inko hissed at the man he couldn't see, "Is my baby going to be alright or not!?"

"Mrs. Midoriya, please," the man said, "We're doing everything we can to figure this out, but from the looks of it, that...mutant that attacked your son injected him with some form of the same mutagen we found in its makeup."

"And what the fuck does that mean?" Ah, there was Kacchan.

"It means that whatever that thing was," the doctor sighed, "Young Izuku has a very strong chance of transforming into the same species."

Izuku grew cold upon hear this, and flung the covers off of himself, moving toward the window with surprising speed.

"It's been two days since he was attacked," Inko said to the man as she fretted over her son, not knowing of his escape, "If he was going to turn into...whatever that monster was, don't you think he would have shown more signs than this?!" She demanded, flapping the papers she held in his face, "I'm not stupid! This is a Quirk analysis! You think that thing passed some of its strengths to him, and you want to know how to do it again!"

"That's not true, Ma'am, I'm not a mad scientist, thank you very much," the man said, glaring slightly, "All that we do know, for the moment, is that the venom from the bite is still in his system, and changing him somehow. His physical appearance has already drastically changed thanks to the muscle toning. His strength is well beyond that of any Quirkless human now, and beyond that of some with Super Strength. We simply want to make sure its safe to be around him before allowing you to see him. If it turns out that- " Katsuki had had enough of listening to the man, and grabbed him by his coat, hauling him out of the way.

"Enough with the bull shit, we're seeing Deku, whether you like it or not!" The Explosive Quirk user snarled, and slid the door open...only to find the room empty.

Inko and the doctor were right behind him, the mother gasping when she saw the window open. "We...we're on the fifth floor!"

"I'm calling security!" The doctor shouted, "I'll have every Hero in the city watching for him!"

"Don't you dare hurt my son!" Inko snapped at him, using her Quirk to stop him in his tracks. "He's not at fault in any of this!"

Bakugo growled and pelted down the hall, "I know where he usually goes. I'll find him!"

{勇者}

Night had fallen long before Katsuki was able to find his friend. The reason being that Izuku Midoriya was staying well away from populated areas, afraid of what he would do if the mutations were taking place as the doctor said. Currently, he was huddled in a beach side garbage dump. It seemed a good place to hide until he was sure whatever was happening to him would actually happen.

But things weren't so easy. His hearing alone was so much stronger that he could hear nearly a mile into the city, and it was driving him crazy! And then there was his sense of smell. The garbage around wasn't smelly, but he could smell the oil and grease wafting up from some of the tools and old appliances. His sense of touch was stronger now. The grains of sand felt like steel mesh grinding against his skin, even through the hospital clothes.

His body wasn't his own anymore. He wasn't the scrawny little Quirkless kid he used to be. He was...stronger...faster...His flight from the hospital had been so bizzarre...

His wrists hurt. Looking at them from where he sat, he could see that the under side of his wrist seemed to have a small bulge on it, the same thing appearing on the opposite. The top, just behind his wrist, however, now had an open slit...

Curiously, he clenched his left hand into a fist...and out came a long, sharp barb. It shocked him so much that he fell over, striking his head against an ice box as he did, unconsciously pressing his middle and ring finger to the base of his palm. Immediately, in response to the simple touch, a line of...webbing shot out from the bulge under his wrist.

It attached to a stove on the top of a pile of trash, getting yanked down as he fell.

Sensing the danger, he scrambled out of the way of the old appliance, he lept into the air, twenty feet into the air, flipping around and landing to perch lightly on another pile. Looking at the mess he'd made, he looked down at his hands, clenching both hands into fists, sprouting his barbs from both arms, jutting out over his fists like a built in switch blades.

Curious, he pressed his index and middle fingers into his palm once again, aiming carefully at a hub cap. The webs came out again, attaching to the hub as Izuku grabbed the line before he lost it, noting that his reflexes were much quicker than before. He gave the line a yank, and the hub cap came flying at him. He caught it easily, smiling for the first time all day as he stood up.

"I've...I've got powers...I've got powers!" The boy crowed, elatedly jumping into the air, flipping end over end, landing on his perch. "Maybe with this, I can - !"

The hairs on the back of his neck rose and stiffened, as did the ones on his arms. Sensing a threat, he whipped around, seeing nothing...except...a very...very familiar Hero.

"GREETINGS, YOUNG MAN!" The unmistakable voice, and beaming smile of All Might hollered, "IT SEEMS THAT YOU'VE CHANGED SINCE I LAST SAW YOU!"

"A-A-All M-M-Might!?" Izuku floundered and fell off his perch, bumbling down to the ground into the waiting arms of the world's Number One Hero. "Why...how...when...?!"

All Might chuckled, setting the boy on the ground, "Well," he said, speaking normally, "that just leaves out 'where' and 'who' doesn't it?" He joked, smiling widely, "But that's for another time. Tell me, what are you doing out of the hospital?"

Izuku looked down in shame, and fear, "I...I heard the doctor saying that I could turn into the same kind of monster that attacked me...and I don't think I should've stayed at the hospital if I was just going to change into one of those things and hurt people."

"Hm, and I also heard that you gave yourself up to that thing in order to stop it from going after anyone else, am I correct?" He asked, gaining a nod from the boy, "I see. Then you must know that what you did was extremely reckless, and would have made that dear mother of yours throw a fit if you'd actually gone and died on her. Not to mention that loud friend of yours was howling like Present Mic after you collapsed."

Izuku nodded, "I know it was dumb, but I just...I moved without thinking when I realized it was just after me, so I thought that if I let it take me, then - "

"It would leave the people alone long enough for help to arrive, and place you in a body bag," All Might surmised, sighing, "Young man...you are - "

"Stupid?"

"A true Hero," All Might smiled, shocking the boy as he snapped his eyes up, "Yes, I've heard that you didn't have any Quirk abilities until now, since that monster seems to have unintentionally gifted you with its own abilities, but its not powers that make a Hero." He said, and poked Izuku in the chest, "Its the strength of their heart, Young Midoriya, and you, my boy, have a heart made of pure gold."

Izuku felt tears welling up in his eyes as his Hero spoke to him with such kind words, "I wanted to be a Hero so bad...even when I didn't have powers..."

"If you'd said that to me two days ago, I would have told you to give up," All Might smiled, "But you proved, beyond any shadow of a doubt, that you are a Hero...so, Izuku Midoriya, what do you say to letting me train you for the U.A. Exams coming up?"
