CHAPTER ONE: A NEW HEIR

A young male about seventeen sighed after picking up his notebook, thankful that it did not fall in the pond. He stands. At 5ft 3" and has black hair with dark green highlights and emerald green eyes. He wears a school uniform that consists of a black blazer with gold colored buttons and black pants with brown polished shoes.

"Damn it, Katsuki." He muttered as he wiped some the dust off his notebook. "Will it kill you not to be an asshole one day?" He then placed his book away in his bright yellow backpack and made his way home, wincing all the way from the pain wracking through his body. "What…to cook today." He muttered through gritted teeth.

The teen was now limping through the tunnel to make a quicker way home.

"I found a human shield." A gurgle male voice muttered from bellow the green haired teen as he passed a manhole.

Izuku heard the manhole behind him popped off followed by a mass of sludge with yellow sclera, red eyes, black pupils, and large teeth ready to encompass his form.

"Time for me to take control!" The sludge being shouted.

Izuku ignored the pain in his body and moved to run, but was instantly caught by the towering mass. "Gha!" He let out as the force slammed down on his body.

"If it weren't for that asshole, you would not be in this situation." The sludge man chuckled as the teen struggled against his hold. "Nothing you do is gonna help, kid." He then pulled the greenette into his body, constricting his movement. "Now this'll only take about...six minutes or so."

Izuku felt something forced down his throat, his eyes widened as he felt that the sludge was trying to get into his body. Despite the pain, he struggled as he felt that he couldn't breathe. 'He's trying to take my body! I need to get out! Somehow! Some way!'

The sludge man frowned as the young boy was struggling. "Hey. Stop moving, brat. You're being annoying."

But Izuku didn't listen; he fought to get out, his will to live strong. And the villain was getting annoyed by this.

"I...AM HERE!" A male voice bellowed, someone leaped out of the manhole.

He stood at 7ft tall with muscles. He has blonde hair that's combed back with two large strands standing up like antennas that swayed back. His eyes are somehow over shadowed by his eyebrows and a large beaming grin on his face. He wears a white shirt that shows his muscles and green cargo pants with large pockets.

"All Might." The sludge villain growled. "I thought I lost you."

'A-All Might?' Izuku thought in shock.

"As you can see, you haven't." He took a step forward. "Now release the hostage." He demanded.

"Make me." The villain growled as the surprising still struggling Izuku was being forced fed by more of his mass.

The man did. With a step, he was before the sludge man in an instant, his left arms cocked back. "Smash!"

The hero swung his arm in a hook close to the villain.

What followed was a gale storm, sending the villain and the teen flying back.

The blonde man was quick enough to grab the boy.

"There we go." He smiled after putting the boy on the side. He then looked to see the scattered sludge began to gather. "I'll have to detain you." He muttered as he walked towards the recovering villain with a purpose.

"Ugh..." Izuku groned as he shook his head. He looked around and noticed the tall hero closing the cap on a large plastic bottle. "All Might." He spoke with strained voice cough.

"Easy, lad" He patted the boy's back and gave him grin. 'That's one hell of a recovery he has.' He mentally complimented. "Hello, shōnen." He gave a two finger salute. "You really held yourself there."

"I just had to survive long enough." He scratched the back of his head and then bowed at the hip. "Thank you for saving my life."

"No thanks needed, young man." The muscular man gave a hearty laugh. "Now if you'll excuse me." He patted the bottle. "I'll need to bring this one here to the proper authorities." He turned and was about to leap.

"W-Wait!" Izuku held his arm out as he ran towards the taller male.

All Might stopped and looked at the boy running towards him. 'I have some time.' He decided. "What can I help you with, shōnen?" He asked.

"I'm really sorry for taking your time, but I have a question." He stood before the Symbol of Peace. "Is it possible...that I can become a hero?" He asked. "Even if I don't have...a Quirk."

All Might's grin shrinks a bit. "I'm not sure that I have the right to answering you that, young man." He replied. 'But he needs to hear this.' "I cannot simply say 'You can be a hero even without a Quirk'." He sighed. "If you want to help others, you can also become a police officer. It's not a bad job and you still get to save people, albeit indirectly. But you must also consider what the real world can offer you."

Izuku sighed and nodded. 'I knew it all the time. I just needed someone to lay it home.' "T-Thank you, All Might." Izuku rubbed his eyes. "I'll leave you to your business." He turned and walked away, his shoulder slumped and head down.

'I wish I can offer better words, shōnen.' The larger male thought and mentally sighed. He then felt the bottle shaking and looked down to it. "Time to bring you in before you regain consciousness." He decided. With that he leaped up, breaking the ground from his force. After leaping over yet another building he felt a sudden pain in his chest and began to go into a coughing fit. He then crashed against a wall, but managing to hold on to the ledge of the roof. He then pulled himself up and panted, smoke emitting from his body.

"Shit...not yet." He panted, his voice now sounded raspy and grave at the end. He reached up and wiped his mouth, blood smeared over his wrist. "Damn it." He panted. "Mine time's up."

The man was now a form of his former shell. He was shorter, standing at 5ft 4" and had a rather thin and lanky build. His eyes were deep and sunken showing that his sclera were black and bright blue eyes. His hair was swept back with two long stomach length bangs that ended with tufts at the end. His clothes were extremely baggy, his shirt several times larger that hung off him, his pants sagging by the hips and look to be able to house his entire body if need to be.

What he did not know that after he crashed into the wall, the bottle containing the Sludge Villain popped out of his pocket.

HOCF

A female about sixteen was making her way from school after saying goodbye to her friends. She is a fairly tall teenage girl with a rather mature physique, considering her age. She has long black hair that is tied into a spiky ponytail with a single bang hanging on the right side of her face and onyx eyes that point slightly inwards, which seems to resemble a cat. She wears a red shirt under a black blazer over her DD-cup bust with school emblem on the right breast and red knee length skirt.

Thunk!

"What was that?" She gasps and looked to where the sound came from. She heard something rattling inside and sound like plastic creaking. "That doesn't sound good at all." She muttered and moved further away.

"Damn you, All Might!" A male voice bellowed with a gurgled tone as a creature burst out of the trash bin. "I'll fucking murder you and that runt!" To the female's opinion, he looked to be made from some slime and was dark green in color. He has large sharp teeth and big, round yellow sclera. His height far outclasses her.

'He didn't see me yet.' The female thought. 'If I can get away without being noticed, I'll be able to warn the police and they'll call a hero.' She mentally nodded at her plan.

"Ha!" A male's voice laughed as he came around the corner of the alleyway. He is of average height, with a slim but muscular build and lightly tanned skin. He has short, spiky ash blond hair that has choppy bangs that come to his eyebrows. His eyes are sharp and thin, and are bright red in color. "Fucking Deku and his shit. We thought him a lesson again. I wonder about those test results will be Monday, huh?"

The other two males are not so important.

"Four new bodies to take!" The sludge man laughed, turning to them with a wide grin. "Choices. Choices."

"Run!" The shouted as she did so, prompting the three boys to do the same.

"Oh no, you don't!" The sludge man shouted as he stretched his limb towards them.

"Kya!" The girl screamed as she was caught by her legs, fell, and was being pulled back. "Let me go!" She shouted. "Help!"

The three boys stopped running and looked back to the girl being pulled towards the sludge man. They then run, the ashy haired male looking a bit longer before following his friends.

'Not my problem.' He thought as he ran.

"Don't worry." The villain chuckled as he forced a portion of himself down her throat, the sounds of her choking not even bothering him. "It'll be over soon." He laughed as he continues to forcefully feed himself to her.

After a few painful minutes, she was beginning to see black spots in her vision, showing that she was losing consciousness. 'I have to stay awake.' She thought.

Several heroes had already tried to get her out, but it was no use since they couldn't get close enough.

'Am I…going to die?" She thought as she looked over to the gathered crowed to see what was happening. 'Someone…" Her eyes were beginning to close a she held her hand out to the crowed, tears welling up. 'Anyone.'

Save me…

"GOAAAAAAH!"

The crowed and the present heroes gasp as they saw a teen running forward towards the trapped female.

"What are you doing?!"

"Get back here, kid!"

"He's going to get himself killed!"

The trapped female was shocked at the sight of a green haired teen rushing towards her near unconscious form. 'He's...coming to save…me?'

"You!" The sludge man bellowed, sending tendrils towards him. "I'll kill you and then All Might!"

But the boy managed to avoid the tendrils, albeit clumsily, and reached close enough.

"Take this!" The teen threw his bright yellow bag, its contents spilling in mid-air.

The monster's mistake was to look up and get a face full of books. His grip on the female loosened due to contents hitting his eyes and someone pulling his hostage out.

'He freed me?!' She thought as her consciousness was returning, but her body felt weak.

Izuku managed to pull her out, tumbling back due to how much force he used. "I gotcha!" He spoke, sounded both scared and relieved as he looked at her with shimmering green eyes.

"I'LL FUCKING CRUSH YOU!" The slimy man bellowed out as he raised his sludgy fists, their size increasing tenfold.

Izuku turned his body around, hoping to shield the female he was holding in his arms. 'I hope she survives this!' He thought as he held her close and looked at her with a nervous and yet brave grin. "D-Don't worry. Your g-going to be…alright."

'He's...going to take the brunt of the force?!' She thought in shock. 'Why won't he use his Quirk?'

Izuku held her close, covering her body as much as he can. 'A hero must put the lives of other above his own.' He thought with a determined grim look.

BOOM!

Izuku felt a wind force hit his back, but nothing more.

"Pathetic." A man spoke.

The verdette's eyes snapped open, looking back to see the Symbol of Peace holding back the large Sludge villain's hands with no problem.

"A...All Might." He muttered.

'The Symbol of Peace?' The black haired female thought.

"I'm such a pathetic fool." He scolded himself. "I reprimanded you, and yet, here you are, saving that young woman's life without hesitation."

"M-My body just...moved on its own." He muttered.

The man smiled. 'I was a fool to say those things to him.' He thought.

"ALL MIGHT!" The sludge man shouted.

"Smash!" He sent an upper cut, blowing a hard wind that blew everything away, safe for the two teens behind of him.

Izuku noted that the man coughed a bit of blood as the wind receded.

After a few seconds the cloud gathered and began to rain.

"It's raining." One of the heroes, Death Arms, spoke in wonder. He is a muscled tanned skin man that wears a metal headband over his forehead. He wears a purple metal vest that colored purple with bolts and crews in it along with a pair of black pants and brown metal shoes.

"He made the weather change with the force of fist alone." A woman named Mt. Lady that was a giantess spoke in wonder. She is voluptuous young woman who has purple irises and white pupils with long, voluminous, creamy blonde hair curled into two strands to frame her face. Her costume is composed of a purple and cream colored skintight leotard, which is accented with orange stripes. The suit appears to have a pair of purple gloves with orange accents on the edge of the cuff. The design is similar for her "boots" which are cut off at the thigh in a deep v-shape. The suit also has three peculiar orange diamond shaped dots on the purple top that are located under her chest. She also wears a purple mask that covered the lower half of her face and purple curved horn-like protrusions on the sides of her head.

All Might staggered a bit, raising his right fist in victory and mentally happy to save the two teens behind him.

Izuku sighed as he was being scolded by the heroes present, sans All Might. He didn't care as he was focused on the female that being tended to. 'At least she's safe.' He thought and as he took more of the heat.

'He saved me.' The female thought with a faint smile and happy tears in her eyes. 'He's my hero.' The female placed her hand on her chest, her heart beating a mile a minute. 'This feeling.' She sighed. 'I'll find out who he is.' She decided to find the green haired teen that risked his life to save her own.

The male teen with the ashy blonde hair from earlier was staring at the green haired male with gritting teeth, his palms sparking with miniature explosion. "Deku..." He gritted his teeth in anger.

HOCF

The teen was walking, his head down and eyes glazed with tears.

You're worthless!

He shook his head, green tinted bushy hair swaying from left to right.

Why did you have to that, you idiot!? You could've gotten yourself killed!

He then frowned.

Why don't you just go to the top of the school building and drop right off it. Hahaha! Maybe you'll get a Quirk in the next life!

He then wiped his nose.

I'm sorry. But without a Quirk, you cannot be a hero.

"Fuck…" He muttered to himself as he gazed to the skies, his green eyes shining under the moonlit night. "Is being Quirkless really a burden?" He asked himself decided to go off track, taking a route that leads to a large clearing. 'At least that girl's safe.' He thought with a small smile, feeling rather proud at accomplishing a small part of dream. "I don't even know her name." He sighed. He was rather surprised at the action he did himself. "I wonder if mom and dad would've been proud?"

The area was suddenly bathed in a red color, cutting Izuku from his thought.

The teen stumbled and fell back on his ass at the sudden environmental change, his face filled with shock. "What going on?" He spoke and a bright orange glow appeared a few feet away from him. His body moved on its own and ran to a tree, hiding behind it.

A bright light followed the glow. And then...

ROOOOAAAAR!

Izuku covered his ears at the loud roar that suddenly erupted within the area. He swallowed a lump in his throat and peeked behind the tree only to see a sight that will be stuck with his for the rest of his life.

It was a dragon.

The boy ducked back behind the three after seeing the dragon. "A person with a dragon Quirk?" He panted. "Is it somehow related to Dragoon Heroine Ryuku?" He looked about. "Or is it a villain that got away from a hero like the Slime from earlier today? Is this some sort of special Quirk? How did it do it and how did it get here? Does he have some sort of social teleportation Quirk too?" The boy ended up going into a muttering monologue, coming up with theories related to the dragon behind him.

"Boy." A deep guttural male tone growled from where the dragon is. "Come out from there. I can hear your muttering and smell you."

Izuku stiffened and mentally berated himself. 'Fuck!'

"Come forward or I will erase you from existence, boy." The dragon breathed.

'How did I get into these situations?' He thought as he stepped from behind the tree, getting a good look at the dragon.

He seems to tower at the estimated height of six stories in length from snout to tail, which ended with a large chunk of it being sliced off. A long snout and its maw filled with adult sized and very sharp bladed purple teeth. His wings span seems to block the sky, judging by how it compensates for the large beast's size. His head was adorned with three sets of horns. One set seemingly originated from the joint of the jaw and stretched forward, flanking the mouth. The second set is from his forehead pointing upwards at a bent angle. The third pair is at the back of its head matching that of a goat's. He also noted how the dragon's body was adored with scars showing that it spent its life on the battlefield. He licked his chops, showing his paper white and forked tongue and freaking out the young male. He also has three sets of red eyes with black slit pupils within the depths of purple sclera.

"Woah." He couldn't help staring at the dragon in awe.

'This human seems to be more in awe of my appearance than fear.' The dragon thought.

"A-Are you okay?" The boy asked, causing those understandable intimidating eyes to blink.

"Do you not fear me, boy?" The beast asked.

"I-I'll admit that I'm scared. Damn scared, even." The green haired teen confessed.

A snort of amusement blew from his nostrils, blowing the boy back by a few paces. "To actually find a human, a boy no less, to show more fascination then fear, but to still stand before me." He then winced with a growl as he lowered himself on his stomach. "Such brave moments in my last hour."

"L-Last hour?" Izuku repeated and then his eyes widened at the sight of an extremely large sword impaled into his back. "Oh shit." He muttered at the sight of the blade.

The dragon looked at the boy. "What is your name, boy?"

"Midoriya Izuku." He answered with a squeak. "What's your name?"

"My name is Fafnir, Midoriya Izuku." He hummed. "A strange name indeed. Then I truly have traverse to another dimension." He huffed. 'Lucoa would certainly hold that over my horns for millenniums to come.' He thought. 'But sadly, the blade has been specially made kill me.' He growled as he reached up and grasps the blade's handle. "I refuse to- RAAH!" He howled in rage and pain as he felt a pain filled shock ran through his body, releasing the handle and laying back down.

"Hold on! I'll get help!" Izuku immediately ran. "I'll be back with a hero and-". He promptly slams into a barrier and grunted in pain as he fell down. "Ow."

"It's no use, Midoriya Izuku." The dragon spoke in low shallow breaths. "That barrier will remain until my last moment."

"Damn." Izuku stood up and looked down. "I'm sorry."

"Why do you apologies?" He asked.

Izuku contemplated, but decided to tell the dragon his life's story.

"Foolish humans." Fafnir growled. "To have decided your life's worth simply because you are…Quirkless."

"That's how it is here." Izuku replied to the dragon, having been told of his life story as well. "I really admire the heroes, Fafnir-san. But since I have no Quirk." He sighed.

"Hm…" Fafnir looked at the boy over. 'He does look normal.' He mentally commented. 'But I can see it in his eyes, his aura. His wanting to prove them wrong. Show them that he can become greater.' He closed his eyes. 'I am near my end and I cannot sire an heir.' He then opened his eyes, focusing on the young male before him. "Izuku."

"H-Hai." He looked to six eyed beast.

"What if I told you that you can become this 'hero' you so wish to be?" Fafnir offered.

Green eyes widened. "W-What?" He muttered, hope glimmering in his eyes. "You...you mean it?"

"I do." Fafnir huffed. "I'm dying and I am near death. The sword impaled in me has been specially made to kill me." He grumbled. 'Damn gods and their foolishness.' "I have decided that you shall be my heir. The one who will live on in my place."

"E-Even without a Quirk, I'll make you proud! I promise!" He vowed, fist clenched and eyes filled with determination.

Fafnir grinned and then chuckled. "Then do me a great honor." He requested. At the boy's nod, he continued. "Partake in my flesh and blood."

"..." No words or thoughts could've processed in the teen's current blank mind.

"I know this may seem strange, but it is tradition that a dragon devours another to inherit their will. It was never done between humans and dragons. You will be the first." He explained.

The boy swallowed a lump and took a shaky breath.

"With that, you will become powerful, your body will adjust to it in time. But will happen about an hour after consumption." The dragon explained. "This is your only chance. Will you take it or let it slip through your fingers?"

"I'll do it...Fafnir-san." Izuku breathed. "I'll carry on your will. I'll be greatest hero. And I'll be a damn powerful dragon that will make you proud!" He declared.

"Hahahahahaha!" The dragon suddenly laughed. "You carry the will of courage, boy!" With that, he rose to his towering height. "I, Head of the Chaos Dragons, Fafnir, have declared you, Midoriya Izuku, my heir! You will inherit my skills, pride, magic, polymorphic abilities, and martial prowls!" He raised his left claw and rammed it into his chest, piercing hardened scales. Izuku had refused to turn his eyes away, determined to see this to the end.

With a grunt, a jerk, and the crunching of bones, Fafnir ripped his heart deep red blood bursting from the self-inflicted wound, spilling the area around him and the some splattered on the boy's uniform clad form.

"There." He panted as he placed his still beating heart before the boy, the size reaching up to the teen's own and its width was twice the boy's. "Now...eat." He breathed he rested on his stomach.

Izuku reached forward and placed his hands on the dying dragon's heart. He can still feel it pulsate under his palms. He then leaned forward and opened his mouth.

Chomp...

The boy grimaced at the taste, but fought through it. 'Taste like something I don't even want to think about.' He thought as he swallowed the piece of flesh. "?!" He blinked as the taste to something rather exquisite.

Fafnir watched as the boy's eyes glazed over and he suddenly began to indulge in his still beating heart, lying there in wait.

It's been near an hour and Izuku was holding at most 8oz left of the large heart, his figure seemingly changing to a healthier physic.

Once the last piece was swallowed, his eyes were back to normal and he blinked in surprise. "I...I ate the whole heart." He muttered in disbelief.

"That's quite the hunger, boy." The dragon chuckled, his red eyes seems to be lowly dimmed. "This is only the beginning. Soon your body will change. It will be best that you go home."

Izuku nodded and then he looked over himself. "Damn. I'm covered in blood." He sighed, somehow not even bothered by the fact of it. He then fell forward, his body unmoving.

"An interesting boy, indeed." Fafnir hummed as he gently rolled the boy unto his back with talon tipped finger. "He wished to become a hero, hm." He leaned forward, tapping his forehead with a gentle nudge of his talon. He then closed his eyes, focusing on the memories as he himself lived through it. He allowed a withering growl to escape his maw. "This boy WILL go far." He declared as he laid his body around the boy. "I believe a hero will need a...costume. I can provide you with that." He glanced at the blade lodged into him and allowed a savage grin. "And some heroes...use weapons." He then closed his eyes, his body and the sword breaking down into dark purple particles.

May they tremble at the roar of a dragon!

Harem: Working on it. Might be big though.

AND THAT WAS CHAPTER ONE
