This is a fanfiction: That means I don't own the characters or setting, and therefore paying me for this is just gonna get us all in a whole load of trouble.
Foreword: The idea of a "Dragon Contractor" is being used with permission from Writer Azdrgn (of Jaune Ryu-Long Dragon Contractor) he spitballed this particular fic, where Izuku forms a dragon contract with Bahamut, in the AN's once. I sent a PM asking to take on this idea, a request he granted. Thank you. And Merry Christmas.
In a time forgotten by man the Dragon's reigned over all, however they believed that the time had come for other races to shine. To facilitate this, new worlds were scouted and in time a world in desperate need of heroes was found.
The Dragons then chose their representative carefully. The vanguard would forge a contract with one of the fledgling guardians of that world in the hopes of bringing about a new dragon clan. This Dragon though once derided as weak for his lack of elemental affinities was now hailed as the strongest dragon there was. His name was Bahamut.
Upon this world so desperately in need of heroes, yet so seemingly filled with them, Bahamut made his choice. A small child whose dreams of being a hero had just been dashed by a doctor's cruel words, and an extra joint in his pinky toe of all things. That night when Izuku Midoriya sat in his room crying because of his Quirklessness, Bahamut dragged the boy into his mindscape for a little chat.
Izuku was confused and for a few moments scared "Calm Down Izuku. You will not be harmed here." said a deep voice from the blackness. "We are inside your mind, and I have something rather important to discuss with you."
"Show yourself!" Izuku yelled into the darkness, having mustered his courage.
"Very well." The darkness was blown away and in its place a grassy meadow appeared. Directly in front of Izuku there was a colossal black dragon. Standing on two legs with its forelimbs crossed. It's belly was brown scaled and its eyes were glowing green. "I am Bahamut!" it roared.
Izuku wasn't phased as that roar had more of a 'respect me' vibe to it than a 'Fear me' vibe. "Okay Bahamut-sama why do you need to talk to me?" he asked cautiously. Imaginary or not this dragon wasn't to be trifled with.
"We dragons exert our will by forming clans of humans and other races upon various worlds to provide them with champions. These clans draw power from their contracts with our race in return we gain influence and experience we would otherwise be unable to acquire." He explained "I'm asking you to form one with me."
"Why me? I'm quirkless, how much good could I do?" Izuku was getting curious and had heard the phrase too good to be true. "What would I have to do for this contract?" After all you can't get anything without giving something in return.
"Protect those deserving protection. Defeat those who endanger the innocent. Never let someone trample your pride again. Another thing, a clan means a new generation, and that requires children, so you will need to get married eventually." said the dragon.
And with that knowledge, that accepting the contract would just mean he'd live the life he was already trying for only without letting romance fall by the wayside like (in his opinion) far too many pro heroes.
"I accept." Izuku spoke, no longer afraid of this being who had just shown him the way to his dreams "Do what you need to Bahamut. It will make my dream come true after all won't it?"
Bahamut nodded and spoke once more "In order for this to occur I must first make some alterations." Placing one talon against the boy's forehead he chanted "For it is in hope we find the strength to continue the battle. Through this we are reminded of our oath, a promise to protect at any cost. I unleash your soul and by my will empower thee!"
Dragged back to reality a gentle green light enveloped Izuku as his mother, Inko Midoriya, walked into the room expecting to find her son broken and hopeless, instead she found him crying tears of joy "Look mommy I have a quirk!" he said more happily than he'd been that day.
The doctor had just said that it was impossible and yet here it was, her son had powers, despite having two joints in his pinky toe. It was nothing short of a miracle. She immediately contacted her husband to tell the amazing news. Hisashi frequently took overseas jobs, but such allowed him to ensure his son's dreams.
Izuku decided to hide his quirk as best as he could after all Katsuki would probably pick a fight if he knew worthless little Deku had a quirk, and that would land them both in a heap of trouble. Life continued as normal but now Izuku wouldn't get hurt so often.
Training to develop his physical abilities, and perfect his mastery over his contract left Izuku with a few problems. One how to train without tipping Katsuki off to the fact that he had a quirk. Two how to hide the sheer range of abilities the contract gave him, the energy manipulation was one thing but according to Bahamut he'd be demonstrating wings eventually which was decidedly not normal.
Eventually he decided to train his body by sparring against various dojo's while building his bond from the contract in seclusion. As he did this he learned of the worlds that the dragons had inhabited before and wars they had fought.
Through meditation he gained the ability to cover his body in scales, and by the same process the same insults that his former friend Katsuki Bakugou showered upon him were washed off. The bully had no idea that he'd been tickling a sleeping dragon and that was just how the dragon liked it.
No matter how many times Bakugou tried to make his life miserable, no matter how many times Izuku took a beating from the cruel boy his former friend was becoming, Izuku never once struck at him, never once cried outwardly, and when he did cry it wasn't for himself. Instead he cried for the monster his friend seemed bent on turning into and desperately hoped for some way to stop it.
TIme went by and both young men grew stronger both in body and quirk. Facing Katsuki's explosive sweat was a risky proposition one the battlefield of course, but such a thing pales in comparison to the might of the Dragon King. Katsuki's confusion over Izuku (to him Deku) being able to walk around standing tall grew as well.
It all came to a head in their last year of middle school- ten years had passed since that day when Bahamut had formed the contract with him. Their homeroom teacher was supposed to hand out career objective forms that day but "With amazing quirks like those you'll all be aiming for the hero track."
Bakugou scoffed "Teach don't put me in the same category and this fucking cannon fodder. I'm gonna be the first from this crap school to attend UA and then I'll surpass All Might." in his typical crude and arrogant fashion.
The teacher sighed, as Bakugo had been a problem child despite his ambition to be a hero. The faculty only put up with him because of his good grades "Sure your grades are good enough to pass their entrance exam. But frankly if you're going to be a professional hero, you will need a serious attitude adjustment"
"Yeah right." The white haired bully spoke "I am the only one here worthy to attend UA. If I'm not good enough who here is?"
The teacher's response nearly provoked a confrontation that had been a long time coming "Midoriya seems to have the personality necessary and he's aiming for UA as well."
Katsuki was dumbfounded for a moment then he rapidly became furious. He charged Izuku who'd been writing in his notebook of data on various heroes and villains (their Quirks, tactics etc) was simply annoyed "Deku you worthless, quirkless piece of shit why I oughta-" Yelled Bakugou.
His efforts were in vain though as Izuku flared his aura rendering Katsuki's attack harmless "Do what? Try and murder me? I assume you know how that would work out for your wish to be a hero." Glaring into Bakugou's eyes he admonished the bully.
"I'll only say this once, so you'd better pay attention- a person's worth isn't determined by their powers. Even if it was, Quirks aren't the only form of power out there." Izuku packed up his stuff "Where I attend high school is none of your business. If you're going to lose your cool over a choice someone else made that doesn't affect you, well that's your problem."
Secretly relieved that Bakugou hadn't seen the contents of that particular notebook (Carefully labeled in Dutch to prevent anyone from realizing the horribly embarrassing secret within) Izuku put it way finally. Later when Bakugou accosted him after school Izuku lost his temper and slapped the aggressive idiot out of his way.
Dropping off his stuff at home, Izuku changed into a smarter jacket and headed for a rather important assignation scheduled for that day while trying to put his former friend's attitude out of his mind. Why had Katsuki gone so far off the trail? Didn't they both admire the same man, the number one Professional Hero, All Might?
How could admiration for the same person forge two such divergent paths in life? Where Izuku's admiration for him came from the man's ability to keep a smile on his face no matter how bad the situation got, Katsuki's seemed to stem from All Might's sheer power, completely ignoring the true reason All Might was so popular.
Little did the aspiring hero know that a certain sludge Villain was creeping up on him from behind ready to strike.
"Hmm nice body, mind if I take it for a spin." the monster's voice came from behind. Izuku reacted, flaring his aura and focusing on the link with Bahamut. His body became covered with scales, and the villain was forced back. "Oh come on it's only going to hurt for about forty-five seconds then the abyss awaits!" The villain complained.
"I can't let myself die just yet villain. If I die here then I'll never be a hero. Not to mention the breach of contract such an untimely death would mean." Izuku commented, whilst readying for combat. He wasn't allowed to use his abilities as offensively as he'd liked on account of his lack of a hero license, but hopefully his aura would be sufficient to protect him and keep the villain busy long enough for a pro to arrive.
Looking onto this scene, one Toshinori Yagi, known to the public as All Might was impressed by the boy's abilities, though confused by his words 'Contract, what is he talking about?' he thought, 'Oh well better contain that villain. Pretty annoying that he's managed to evade me this long.'
"TEXAS SMASH!" roared the number one hero, defeating the sludge-type villain with a single punch. The young man gazed at his rescuer, briefly star struck. After all it's not every day when the number one professional hero, who also happens to be your personal idol saves your skin from a super villain.
Izuku stood ramrod straight. "All Might sir, it's an honor to meet you." SInce forming his dragonic contract he'd gained several new theories about the Number One Hero's "Quirk". And he'd wanted to see if those theories were correct "I've been observing you for a while, and a brief internet search indicates that a hero was around who fought pretty similarly to you, and vanished before you showed up."
All Might was shocked: Had this youth discovered the truth of One For All? Fortunately for the secret of his strength the youth's next words proved that theory wrong "Your so called 'quirk' is actually just some sort of fighting style right? One you've promised only to teach to a single disciple?"
Okay so the kid had part of the truth hammered out, but still far enough out that he could avoid the truth. Carefully containing the sludge villain All might attempted to dodge the question "Well maybe that's the case and then again maybe it isn't. Sorry to get you caught up in my Justicing but the sewer in this town are a doozy to navigate."
Bahamut finally decided to speak up even though only Izuku could hear him "Well this one has got to be the single worst liar I have ever encountered. You'd think a guy who can manage to keep his real name and origins secret for ten years would be able to dodge a question in a less obvious manner."
Izuku commented aloud "Well, that look on your face is enlightening. Knowing there'll be an All Might Junior on the loose down the line makes me want to train even harder." After a quick reminder from Bahamut "Not today though- I've got a date later and showing up to those sweaty is just gonna get you in trouble."
All might replied "Heroes often have to let romance fall by the wayside, it'd be a shame for all that potential of yours to go to waste. You could be number one someday with that quirk of yours. Don't squander that potential over some girl."
Izuku was getting annoyed with his idol's cynicism "No sir. The real shame is that the people responsible for protecting our happy lives don't get their happily ever after. Do yourself a favor All Might. Train that heir and then find someone nice to settle down with and hold them tight, you've earned some happiness. Anyone who says otherwise after everything you've done is deluding themselves. You included."
All Might's thoughts on those words added up to 'Well that was way too wise for a teenage boy to say'. Either the kid had someone else feeding words to him or he'd been planning that speech for quite some time. Both possibilities were in a word ridiculous but the words themselves hit him.
True enough his time as a professional hero was running out. The fact that this young man had figured out that his abilities could be passed on (though not the precise nature of those abilities) made it crucial for Toshinori to swear the kid to secrecy at least, but the boy had implied he was interested in being a hero.
Perhaps All Might could make two things all right with one move. The boy's skills and abilities were already impressive and to be honest, the pro figured that the kid had been holding back. Some form of energy manipulation and suddenly manifesting scales? It was almost as if the boy had multiple quirks.
Suddenly realization hit him and he feared the worst, that this boy was among the works of his old foe All For One and might be planning something sinister. In his rush to follow the boy, he got careless with the bottle he'd used to capture the sludge villain, dropping it.
For a certain explosion happy bully this slip of awareness would come fairly close to costing his life…
Katsuki Bakugou was absolutely furious. How dare that worthless weakling try for U.A high?! How dare Deku write him, Katsuki Bakugou, the future number one hero, off?! Blasting his now empty soda can to bits he headed for the arcade to blow off some steam.
"Perfect invisibility cloak with a strong quirk too." Spoke the now rampant sludge villain, before attempting to take control of Katsuki's body and usurp his quirk. The pro heroes in the area, namely Death Arms, Mount Lady, Backdraft, and Kamui Woods responded to the situation almost immediately.
One by one however these responders found themselves unable to do anything for Katsuki each for a different reason. Kamui woods couldn't even get close on account of the victim's explosive based quirk (being a plant had disadvantages). Death Arms couldn't do anything resembling damage to the sludge villain's quasi-fluid body.
Backdraft was too busy trying to contain the flames caused by Bakugou's entirely justified efforts to defend himself from the body snatcher's designs. As for Mount Lady? She'd probably run into the same problem as Death Arms even if she had a good enough handle on her gigantification to get anywhere close without massive collateral damage.
To make matters worse as the crowd was mentioning that All might had been fighting the villain earlier, Toshinori Yagi (All Might's alter ego) was cursing himself for forgetting about the villain in favor of tracking the green haired kid who seemed to have multiple quirks and far too much wisdom.
Izuku passed by the scene on his way to the date he had that day. He wouldn't have even given the spectacle a second look were it not for how many heroes were targeting the same person. When he saw what they were fighting Izuku's blood boiled. Somehow the number one hero had managed to let a low level villain give him the slip.
Somehow despite all his boasts (make no mistake Izuku did respect the other boy's power) Katsuki had managed to get himself captured by said small-fry villain. Shaking his head and wondering why he was doing this, Izuku pushed his way through the crowd with Bahamut trying to talk him out of what he was about to do.
"Contractor, please reconsider! This ruffian has run roughshod over your pride for far too long. He isn't worthy of his dream, your dream. I implore you to leave him to his fate. Such a bully has no right to the powers he was born with!" The Dragon King roared from within Izuku's mind.
Speaking aloud for the crowd (not that he knew it All Might included) and his former friend to hear "Katsuki, I'm not sure how you turned into such a bully or if what I'm about to do will make anything change. What I am sure of is that if I abandon you now, I might as well abandon my dream too." He noticed a text on his phone as he advanced, his date had cancelled on him.
"Well my date just cancelled on me, and look here, the perfect excuse to vent my frustration!" Izuku Midoriya, the first Dragon Contractor of his world, prepared for battle. summoning his scales and flaring his aura, he charged forward, heedless of the danger to himself and committed to his contract and his dream of being a hero!
Okay really I do not approve of how many fans of Izuku x Katsuki there are! If it turns Canon I'm not reading BNHA again. Bakugo's going to be the butt of alot of jokes in this but more importantly- The Pairing! It'll be a surprise but it won't be Izuku and Ochako.
Altered as of 2/4/19 since now there actually is a poll up and running. See this version of the Dragon Contract allows for four retainers marks to be planted, each of these marks alters the gametes of the retainer to allow for their eventual children to be Dragon Contractors as well
This poll, actually the second I'll put up will help me determine which people get the marks in question. Bakugo is not an option as I feel his character arc is too easily handled by the writer of BNHA.
