Prologue: The Awakening
Izuku always felt he was different from everyone else and not because he was quirkless. He didn't feel all that human to everyone in this world of Quirks, Heroes and Villains. It started at the age of 5 when he first discovered he was Quirkless. It didn't really bother him at all since he could still be a hero when he grew up.
Animals were unnaturally afraid of him except for large predators like crocodiles and bears for instance since they seemed to easily enjoy his company along with the occasional black cats. He was abnormally strong for his age being capable of lifting car at the age of 3 and he grew faster too. He looked like he was in 4th grade at the age of 5 standing around 3 ft 8 in size. He could see, hear, smell and sense things far away from him better than those with a sensory type of quirk.
He could run faster than an athlete and was able to take amazing amount of punishment as well. However his interaction with people turned sour and stale real quick. When he was bullied by his former friend Bakugo and all the other kids, he had stood up and defeated them with ease. To everyone, it was impossible that a Quirkless kid could be able to take on a group of kids with Quirks and win.
Teachers had grown to completely fear the boy while his classmates would do everything they can to hurt him either by calling him names like monster, freak or demon and even so far as to throw objects at him or use their quirk on him. Of course Izuku easily defended himself though he realized he was different when one of the kids attacks went wrong. A kid with the ability to create saw blades had accidently shot one off and the blade had taken Izuku's arm off.
Yet Izuku somehow didn't bleed and then his arm had came to life reattaching itself back to his socket but not before sprouting an eye on it's palm along with a mouth and hissed at the kids. That had broke the camel's back. Kids were screaming and trying to flee from him while the teachers and braver ones had all decided to treat him like a monster.
Kids from his room had fled while he was surrounded by angry teachers and malevolent students. He didn't know what to do. For once in his life, he felt completely terrified. 'What are they doing?! Are they planning to kill me? I'm human! I know I am!' Izuku thought as a bullet of air had flew past him. One of his classmates was the one who had managed to fire it though it lacked accuracy. Izuku then had to duck to avoid an explosive punch from Bakugo. When Bakugo brushed past him, Izuku had a caught of glimpse of something.
It looked like strings were attached to Bakugo like a puppeteer was manipulating him. He looked to see the same strings on the other students and teachers with every string glowing a menacing red. 'Those strings! Is someone manipulating them?! Am I being targeted by someone?! What should I do? I can handle kids but these teachers have more experience in their quirks than they do and some of them have deadly ones as well.' Izuku thought a bit concerned as he was forced to dodge another quirk powered attack.
The controlled teachers and students drew closer and closer to Izuku as he was grazed by their attacks since they were so close. He found himself being restrained by a teacher with a hardening quirk and Izuku did everything he could to get away from him but this teacher was much stronger than him and hardened his body even further to take on any of Izuku's hits. "Let me go! Snap out of it! You're being controlled!" Izuku shouted only to get punched in the face by a kid with a super strength quirk.
With each hit, the possessed class did the brighter their strings glowed and stronger their attacks had become. Izuku knew if he didn't get out of their hold then he would die by their hands. However his arms were broken beyond repair, he had large gashes on his body, his face was broken, and his legs were now nubs. He looked over at Bakugo to see him slowly approach him with multiple explosions going through his palms.
"I wonder what demon brains look like? I've wanted to do this for a while now Deku! I can finally prove I'm superior to everyone else and you'll be nothing but an awful memory. After all, we were never really friends. I used you as a stepping stone to success." Bakugo stated as Izuku's mind had snapped. Now he realized what the strings were doing.
They were manipulating a person's own desire and negative emotions because what Bakugo said was the last piece of the puzzle and you know how it made him feel. All those times they played, the adventures they had and everything was… A Fucking Lie! He shall no… he wouldn't stand for it! Every bone in his body was screaming for vengeance even if the bastard kid was being controlled.
If he was going to be treated like a monster then he would show them a real monster! Then Izuku exploded. Authorities and heroes were called to the school while the assault on Izuku was going on. They had received reports of teachers and students suddenly becoming murderous and violent with no reason attacking anyone around them. The heroes had believed that someone with a mind controlling quirk was the one behind this orchestra of terror.
Student and teacher alike were fleeing while heroes were trying to handle the possessed student and teacher body as it became harder to restrain them without doing permanent damage.
Even the Symbol of Peace All Might was having a bit of difficulty and he didn't how much they could take without any precautions. Things were looking bleak when a large explosion ripped through the building and something large shot out of the smoke into the air. The figure was too fast for anyone to track it's movement before they noticed it dart off towards a building.
Suddenly a man was sent flying through the air and landed on the ground unconsciously as all of the possessed suddenly stopped and fell to the ground completely knocked out. The heroes had approached the man and noticed it was actually a villain that they recognized on the most wanted list. A villain with a puppeteer like quirk that could turn any person murderous with his strings.
The heroes were confused on how the man was beaten so easily since he even gave the Number 2 Hero Endeavor a hard time and All Might was busy trying to hold back the murderous population. All Might however had went into the part of the building that had exploded and noticed quite the scene. Those in the room who no doubt had gone murderous were lying on the ground with claw marks, broken bones and a lot of bruises while the room looked like a demon had unleashed hell on it.
'Wait, demon? Could it be?' The blonde and muscular Number 1 Hero thought before he suddenly took off from the scene leaving a variety of heroes confused on the man's recent action. All Might was running through the city searching for the blur that had left the school when the explosion had happened. 'Could the legend Sensei told me was true? Could he have return?' All Might thought as he picked up something coming from nearby.
It was a strange sound that beared the tone of sorrow and fear in its hauntingly ominous voice. However the man recognize what the sound was. 'Is that...crying?' All Might thought confused furrowing his brows as his blue eyes were completely confused on the situation. He then decided to follow the sorrowful cry to see where it lead him. He soon found himself at an abandoned building while the sound grow louder and more clear.
The cry sounded like it was coming from an inhuman male voice that even gave the Pro Hero chills down his spine. Nonetheless, he steeled himself and walked straight in beginning his search. Following the cry, he found himself deeper into the darker part of the building as the voice grew louder, ominous and sorrowful. He finally made his way to the end of it to see a figure at least a few feet bigger than him huddled into the corner. He could make out four large arms on the figure, multiple glowing eyes of red, green, yellow, white and blue and wings on it despite the darkness.
"Everything is alright because I am here!" All Might spoke as the figure lowered the hands on his face down to reveal 3 bright green eyes looking back at All Might. All Might could see the look of fear and betrayal in those eyes as the figure scooted back pinning himself to the wall in fear. "Please don't look at me! Get away! I'm a monster!" The figure's voice spoke terrified.
"I'm not here to hurt you. I want to know what happened back at the school. Can you get out of the shadows so we can talk better?" All Might asked curiously. "No! You'll be just like those others! You'll think I'm a demon of some sort and try to kill me like the rest of those teachers and my classmates at school did!" The figure spoke in fear surprising All Might.
"Are you one of the students that went there who suddenly disappeared? A young Izuku Midoriya am I correct? Plus why would I to hurt an innocent child?" All Might asked as Izuku flinched. "Because I'm not human! I'm a monster! They all saw it and tried to kill me! Those strings only helped them to try and achieve it! No one will accept me knowing what I am!" Izuku shouted with his rough, deep and monstrous voice.
"I'm sure people will accept you." All Might stated only for Izuku to step out of the darkness and into the light as All Might gulped a bit from the kid's appearance. His skin was light blue with black scaly markings, on his shoulders, chest and palms were eyes on each one while there were two on the chest, on his stomach was a large fanged mouth that looked capable of eating titanium, the bottom half of his body was covered in black fur which reached all the way to his ankles revealing hand shaped feet, his hair was dark with bright green thorns coming out of it, on his back were two giant metal wings that looked like something from a horror film, he had two large bat shaped wings for ears, the eyes on his head were a toxic green with yellow iris and no pupils, he had a long tail made of bone and metal spikes, a star shaped stone on his lower stomach though it didn't look like a wound and had the body of a muscular young adult.
Izuku had to be at least 11'6 ft in size in his current state. "Do you think someone will accept me like this?! I look like something from the deepest pits of hell! I'll never become a hero if people are just going to be afraid of me! I'm just a monstrosity! I wanted to be a hero that people can look up to and don't feel afraid by the danger of life! A hero who comforts people with a smile on his face." Izuku stated as he began to cry. All Might bit his lip. He easily understood how young Izuku felt since those with Mutation Quirks were considered monsters by society.
Izuku soon found something wrap around his large frame while he felt someone pat his back. He looked down to see All Might was trying to comfort him. "It's okay. I know how you feel. I've seen the way how those with powerful or dangerous quirks are treated like villains whether by appearance or their power. No one should judge someone else because of their quirk or their appearance. It's their actions that decides on who they are or want to be." All Might began to say as Izuku found himself listening to the man.
"Heroes come in many shapes and sizes looking human or monster in appearance but they all prove that anyone can become a hero no matter how different they are from everyone else. You acted like a hero today by defeating that villain. Even if you did cause some damage, you were just terrified and it's understandable. Young Midoriya, I believe you have what it takes to become a great hero.
In fact you remind me of an old urban legend about a unique hero of old. A hero who despite his powers being absolutely terrifying had went against all the odds to protect the innocent and those precious to him. A man with a quirk just like you that allowed him to transform into a powerful beast and fight off hordes of evil that had plagued the planet long ago. The Demon Hero: Devilman!" All Might spoke as his eyes widened.
There was a hero who had a quirk just like him? Could he be someone like the Demon Hero? Could he be the new Devilman? And All Might of all heroes was supporting him. He wanted to make sure. "Do you really believe that I can become a great like you? Like Devilman?" Izuku asked. "I believe, no, I know you can! I have complete faith! I will do everything that I can to help you! You know why? Because I am here!" All Might spoke as Izuku's heart was soaring.
The young boy had hugged All Might back who didn't resist the hug at all. The hero watched as Izuku had begun to shrink and change reverting back to his human form although he realized that his clothes must have been completely destroyed due to the transformation. The man had taken off his cape and wrapped it around Izuku's small frame covering every nook and cranny before picking the young boy up.
He noticed Izuku had fallen asleep on him, no doubt completely exhausted from his transformation causing All Might to chuckle a bit. 'It looks like your legacy is still alive Akira. This time, I promise you this young child doesn't end up like the others. It's time that Devilman must return to this world and protect it from danger. After all, he might be the one to break this corrupt circle of hatred around the world.' All Might thought as he walked out of the building and into the light with a peaceful sleeping Izuku in his arms.
Izuku didn't know where he was. The last thing he remembered was when he lost it at how Bakugo truly thought of him and his encounter with All Might but the rest was a blur. He had opened his eyes to find himself in a field of black grass off in the distance, no sight of any trees except for the black grass, tough reddish violet ground barely peeking amongst the black and a crimson red sky with a jade shining sun. The place seemed strange yet felt safe to him for some reason. He then noticed something. He was in his new demonic form from before.
"What's going on?" Izuku asked with his ominous voice before he noticed something. Amongst the grass around him were bones of a variety of different animals that reminded him of monsters from a bunch of video games he remembered seeing trailers and commercials of. There tons of them that it frightened the boy so yet somehow he still felt like he was safe and secure. Then he felt the ground shake and heard a booming sound of some kind underneath his body that knocked him off his feet stabbing his wings into the ground.
"What was that?!" Izuku thought as he managed to pull his wings out of the ground when he noticed something dripping from them. It was crimson blood. "Blood? Why did it come from the ground unless…" Izuku asked as he seemed a bit frightened. With all of his courage, he took off into the air flying above. He flew further and further into the sky as he began to make a shape which expanded until he saw what he had landed on earlier. It was a giant demon like being that he woke up on mainly on the demon's shoulder.
The giant had reddish violet skin and was really muscular as Izuku could easily see an 8 pack on the guy, a slightly hooked nose, black fur covering part of his chest, wrists, shoulders and the waist down, completely black bat wing shaped ears, razor sharp fangs peeking from his maw while he was snoring, long black horns in front of a small red diamond on top his head surrounded by more black fur, a long tail with metal bladed spade tip with some exposed bone jutting out like spikes, a star shaped stone in his stomach, hand like feet, metal blades on his arms surrounded by black scales and slash like openings on his back.
The more Izuku looked at the giant demon the more he could see similarities between the demon and him with both of his forms. The demon's fur was wild as Izuku's hair with a slight resemblance to his face and the marks around his eyes, the wing like ears, tail, the fur covering his lower half and even their feet were similar. Izuku was so immersed by the similarities that he didn't notice a pair of giant fingers grabbing ahold his body.
"What?!" Izuku stated completely caught off guard before noticed the single yellow eye of the giant he was observing looking at him with his red slitted pupils on the boy. 'I think I should had paid more attention to his arm moving than focusing on the giant's similarities with me!' Izuku thought as he was brought closer to the colossal's face until they were face to face or more like body to face. "Um...hello…? Please don't eat me!" Izuku screeched as he noticed a huge smirk formed on the massive demon before he let out booming laughter that almost blew Izuku away if he wasn't being held by said demon.
"Why would I eat my own son? I maybe be a bit cannibalistic but I won't even dare eat my own family or children." The demon laughed as Izuku eyes widened and his jaw almost dropped. No wonder why they were so similar but he never remembered his father being a gigantic demon! Of course he never really remembered ever seeing his father or his mother even telling him about his father!
He was bigger than a damn mountain and she was so tiny compared to him! Izuku shoved that thought out of his head since he didn't want to think any deeper into that and he was 5 for crying out loud. Deciding to focus on the demon who was claiming to be his father, Izuku steeled himself and decided to speak. "Who are you? And what do you mean you are my father?" Izuku asked as the demon stopped laughing. He could easily notice a frown on his face and his eyes seemed a bit...sorrowful?
"She hasn't told you has she? She should have told you by now. *sigh* I guess I should explain it. My name is Amon and like you are thinking I am a demon. A long time ago, I used to be human and until my former ally turned against me transforming me into a demon against my will. I managed to kill him but was forced to walk the earth alone growing bitter with hatred and insanity. For centuries I've wandered in the body of a human named Akira then one day I met your mother.
She was a kind and tender soul who was able to break through my hardened shell. Even when she discovered what I was, she still loved me. For once, I was happy after centuries of pain and loneliness. Then one day, a demon had attacked. He cursed Inko with a spell that whittled her life force away and she was pregnant with you at the time. Fearing the safety of you both, I did something to keep you alive.
I sealed myself within you and used my power to help keep your mother alive despite the curse. However when you were born, the curse started to take effect on her. Her lifespan was shortened greatly and I only managed to save 5 years worth of her life energy. The grief had split me into two which is the half you are talking to. The curse would take effect at the time your power awakened within you." Amon explained horrifying Izuku as a mirror appeared before the two.
It showed cops at his home and being taken from the house on a stretcher was a sheet covered body but the hand peeking out was no doubt his mother's. Izuku could easily feel his entire world suddenly shattering. "Mama! No! Mama! This can't be real! This can't be real! You can't leave me! Don't leave me!" Izuku wailed as he tried to reach his mother but he couldn't and the sad look on Amon's face wasn't helping his resolve either.
It actually hurt Amon to see his son like this and watching the body of his lover disappear forever. The mirror moved as Amon took Izuku and laid him on his chest lightly patting him with one of his nails while the boy cried into his chest. Usually Amon wasn't patient with crybabies but this was his 5 year old son. He'll have him toughen up later but right now he knew Izuku needed this. He was a young imp after all.
Izuku had managed to calm down and looked at the mirror with tear filled eyes. It changed to All Might talking with a few policemen. "So what are you going to do with the young lad?" All Might asked with a hint of worry and sorrow in his voice. "It says here that Inko Midoriya doesn't have any living relatives and her husband disappeared years ago. I'm afraid the child will have to be put in the orphanage. Regarding his quirk, I don't think he'll make that many friends or even have a family adopt him with what you told me." The detective answered.
"I can't let this kid end up like his mother, Akira or be in the hands of a villain, Naomasa. This young boy is already terrified of himself and his Quirk when it awakened. He needs someone to look over him and guide him on the right path. He needs a good trusting and loving parent." All Might explained still holding onto Izuku's covered body. "Well I can't take care of him. I've already have kids of my own and I don't think I can handle another. Plus whoever adopts him has to be trained and prepared in case he goes berserk using his quirk. I don't know anyone trained enough to care for him." Naomasa answered as Izuku looked dejected.
"You're wrong. There is someone who can raise young Midoriya. That person is me. I'll be taking care of him. I admit his Quirk took me by surprise but I know in my heart that he is a kind and strong young lad. It's going to be difficult but I know I can raise him as my own. Plus I've always wanted a kid to care for." All Might explained as Izuku was shocked. All Might wanted to adopt him. All Might of all people was going to care for him.
"Heh! Seems my old friend is actually taking up the old favor. I hope he's ready to deal with a Devilman awakening to his demon side. Make sure to give him hell my boy!" Amon laughed as Izuku sweatdropped yet he could feel the demon side of himself was laughing. "You planned this didn't you?" Izuku asked while Amon continued laughing. Maybe everything was going to be fine after all though he wished his mother could stayed with him longer. Now he would become a hero and fight for justice in her honor as the last thing for his mother.
