I watched Devilman Crybaby and I really enjoyed it so I thought, hey why not take some elements of it and put it in My Hero. However, before reading I RECOMMEND THAT YOU WATCH DEVILMAN CRYBABY. It's on Netflix and some plot points will make a bit more sense if you do watch it. So this begins right after All Might tells Izuku that he can become a hero. Anyways, here goes.
ALL MIGHT (MUSCLE FORM)
Izuku was having quite the day.
It didn't start off all that great but he could say with full confidence that it ended up being the best day of his life. Izuku's idol and the number one pro hero, All Might, had offered him his quirk. To be able to accept such an awesome power would finally allow him to achieve his dream.
While becoming a hero was Izuku's number one priority, he had a little something else on his mind.
"OH MY GOD I'M GONNA GET ALL MIGHT'S QUIRK"
This was essentially what had been going on in Izuku's mind ever since he promised to meet All Might at Dagobah beach early the next morning to begin training. His mind was overloaded and he was muttering non stop.
"If All Might really trusts me to have his quirk and really become the symbol of peace can I really live up to his expectations with my body he said I would need to train to get his quirk which is obvious but will I be able to become strong enough by the entrance exam to be able to make it into UA and how will I make time for it in my schedule and that brings up the issue of balancing my schoolwork and…"
Izuku was almost so busy muttering to himself that he didn't notice the steady droning of party music that was beginning to fill the area around him. It was a fast beat that had bongos in the background, giving it a unique sound to it.

"Is there a party going on around here? I didn't think there were any clubs this close to my apartment," Izuku thought as the sound of the music began to get louder in the direction he was heading in.
He didn't really know what it was, but something about the music drew Izuku to it. Maybe it was the calm rhythmic droning, or maybe it was just pure curiosity on where it was coming from, but eventually Izuku was able to trace the sound to an abandoned building.
The rotten facade of the building and crumbling interior definitely didn't give off the impression that there was a party going on in there, but there was no doubt about it, the party was coming from below the building.
"Well here goes nothing…" Izuku gulped as he entered the building and began to make his way down. He was eventually met with a set of large wooden doors with an ominous red border around the edges. He was about to open the door when his better judgement decided to show up.
"What am I doing? This place could be dangerous! I can't go in there and risk my safety when All Might put his trust in me to become the next symbol of peace!" Izuku scolded himself as he turned around in front of the door.
"Although…" Izuku began to slowly turn back.
"If there is anything illegal going on in there, I can report this place to the police and I could potentially be saving lives!"
Upon opening the doors, he was greeted by what some would call the biggest rave they had ever seen. There were huge holographic projections on the wall, neon lights flashing, alcohol, drugs and now the music was so loud it was hard to think. There were at least 500 people crammed together and they were dancing, grinding, and doing… other things of that sort.
There was a group of salarymen in the back right hand corner of the club, sitting in a circle shooting heroin. Their arms dangled from the barstools and traces of cocaine were visible on the table. Izuku cringed as his eyes continued to wander. On the other side of the large room there was a dance floor with light up tiles. Spilled beer bottles and cigarette butts littered the floor, but the people on the dance floor didn't seem to notice. They were grinding on each other with an almost hypnotic rhythm that went along to the music.
Izuku looked around the room without moving. He had trouble taking it all in.
"What is this place?" he thought.
His thoughts were interrupted by a high pitched "Oh my god aren't you such a cute little thing!"
A young woman in her early twenties began to make her way towards izuku. He scanned her from bottom to top. She was wearing glossy red high heels and white booty shorts. Her hair was short and blond, up to her ears and she was wearing dark red lipstick. Izuku's eyes continued dart from top to bottom until he realized that she wasn't wearing a shirt.
Or a bra for that matter.
Izuku's train of thought stopped. He needed to get out of here and report this place to the police. He had to tell this woman that either heroes or police would be arriving soon and that she should leave while she can. However, the only thing that came out of his mouth was,
"B-b-boobs"
"WHY DID I SAY THAT!" Izuku mentally scolded himself for being such a dumbass as his cheeks flushed.
"Oh you like them? I know something else you would like honey" the young blonde said as she pulled out a small white pill and gestured her hand towards young Izuku.
"No ma'am I'm gonna have to be leaving, I don't do dru-" Izuku was cut off by the woman planting her mouth on his and pushing the pill in with it. This forced Izuku to swallow the pill.
He stood frozen as the young woman walked away. She then winked and yelled back at him,
"Have fun cutie!"
Izuku didn't know how long he was standing there. Between getting kissed by a random stranger, and the loud noise surrounding him, Izuku was a statue. He didn't know when it started but he could swear that the room began to spin.
Colors began to take up his vision and change. He started to move and stumbled, which caused him to trip into a partygoer.
"Hey watch it kid!" the clearly drunk partygoer yelled at Izuku. This scared Izuku and under the influence of an ecstasy like drug, he began to panic. He fumbled over to the side of the room and sat down in a corner, tucking his knees in towards his body.
His eyes darted around the room and he was unable to tell reality from illusion. His skin tingled, one minute he was freezing, and the next he was so hot he felt like his skin was peeling off. The floor was warped and the sounds of people's steps began to sound like thunder claps. People's voices became slow and warped, and eventually someone stumbled over to Izuku and said, "Hey kid are you okay?"
Izuku didn't reply, he just sat there with a blank stare and gently rocked his body back and forth in the fetal position.
Time passed, how much, Izuku didn't know. His perception would speed up and slow down without any notice. It could have been hours, it could have been 5 minutes and he wouldn't have known otherwise.
Eventually screams began to ring out from the crowd of people at the dance floor. He looked out into a sea of bodies as people began to run for the exit. There was the grotesque sound of tearing flesh coming from the same direction as the screams.
Blood spilled on the floor of the room as people were being stabbed and slashed left and right. The original culprit of the stabbing was nowhere to be seen and the party had turned into a bloodbath.
He then noticed that while looking in the back right hand corner of the club, the salarymen were no longer there. Instinctively looking for them Izuku looked out to the scene out of someone's nightmares. Some of the partygoers began to change. Limbs sprouted out from where they shouldn't, and extra mouths with huge teeth began to extend from their torsos. He flinched as he saw one of these people, no, creatures, eat another partygoer whole.
"This has to be whatever that lady gave to me right? There are no common quirks that can do this to people, I must be seeing things." Izuku nervously convinced himself, and in his inebriated state, he was able to get his heart rate down a bit.
He saw one creature with pale blue skin, sprout two mouths from her chest and they extended as they began to devour the heads of an unlucky few. Another creature had yellow skin and a crocodile like snout. Four arms sprouted out from the sides of its body and began to mangle the bones of the fallen partiers. It turned its head towards Izuku, its four empty eyes seemed to be staring into his soul, it's large white teeth stained red with blood.
Then suddenly, that same pair of bloody jaws heading towards him proved that whatever was going on was all too real. These people didn't have transformation quirks, there was far too many of them sharing a similar quirk.
(Play Judgement- Devilman Crybaby OST)
Izuku sobered up a bit and rolled to the side, just in time to avoid being turned into that thing's meal. He ran away from the monster, but his weak legs could only take him so far. There were more of them waiting for him in front.
Severed limbs and the innards of killed partygoers were strewn about the room, and Izuku knew that he was next. This was the end.
Izuku began to scream out loud, tears streaming down his face. He stopped running. He accepted his fate. Izuku slumped over and awaited his death.
That was until, he felt a presence inside him. This wasn't a quirk, and it wasn't a person either. It was something far more sinister, more powerful. This evil presence reminded Izuku of what his purpose was.
"Young man, you too can become a hero"
All Might's words echoed in Izuku's mind. He wouldn't let this presence turn him into one of these monsters, one of these DEVILS.
Izuku was going to be a hero that saved everyone with a smile. All Might put his trust in Izuku, and he couldn't just let himself die. He couldn't let All Might down.
A name appeared in Izuku's mind, he didn't know how, but he assumed it was this presence. AMON was the name that he heard. This demon wanted his body, but Izuku wouldn't let that happen, he would win.
"I WON'T LET YOU KILL ME" Izuku roared at the top of his lungs, and as soon as one of the monsters was about to attack him.
It happened.
(0:45)
Izuku was holding the demon's mouth open with his bare hands. His muscles were pulsating with strength, and his eyes were cold, empty, blank slates. He smiled as he tore the demon in half with ease. His skin was beginning to change color, and he had dark circles around his eyes.
He stood there panting for a moment, and his body began to grow. His legs began to grow taller as black fur sprouted out of them. Along with them a long tail of the same color began to extend from his body. Midnight black wings sprouted out of his back and a dark crown like appendage with two portions fanning out grew on his head.
With his eyes red, the enormous shadow that was Izuku let out a demonic roar that pushed the other monsters away from him with it's sheer power.
He charged forward and stuck his arm straight through the abdomen of one of the creatures. It wailed in pain and the barely in control Izuku bit it's head off and threw it's whole body at another creature. The power of the throw caused both of the creatures to barrel into the side of a broken table where they were impaled by the splintered wood.
More creatures came from all sides around Izuku, but he effortlessly massacred them all. It was like second nature to the newly transformed Izuku. For some reason, killing felt normal to Izuku, it felt good. This wasn't Izuku, this was someone else.
Unbeknownst to Izuku, the devil champion Amon had chosen him as his vessel into the human world. Izuku's pure heart and indomitable will, while risky, would prove useful to him should he successfully possess him. He just needed to wait until Izuku's feeble human mind collapsed.
Izuku felt the evil force of Amon begin to take control, he was being pushed out, he was going to lose. Izuku's heart rate picked up as he began to panic.
"What's gonna happen to mom? It will kill her to see me like this, like a monster. And All Might… I'll be letting him down, I'll never be able to live up to his expectations, and all for what? Curiosity about a stupid party. I'm pathetic"
He had given up, that was, until, he realized what would happen if he let himself lose. Amon would be free and in control of his body. He would massacre thousands all because Izuku was too weak to fight him off. He couldn't let that happen, the couldn't let innocent people get hurt.
Even though the room was empty, the real battle had just begun.
"I WON'T LET YOU HURT PEOPLE AMON! I WON'T LET YOU WIN!" Izuku yelled at the top of his lungs.
He heard the voices of everyone who doubted him, everyone who told him he couldn't. He remembered what Kacchan said earlier that day. "Useless Deku. If you want a quirk so bad why don't you take a swan dive off the roof and hope you get one in the next life."
He heard his mother's voice from when he was a child, "I'm sorry Izuku, I'm sorry"
I'm sorry, that was all anyone ever told him. "I'm sorry you are quirkless" or talked about how sad it was that his dream was to be a hero.
All Might was the only one that ever told him what he needed to hear. His words echoed in Izuku's mind again
"Young Man, you too can become a hero"
Izuku realized that if he was going to be a hero, he needed to hold on to his values, no matter what. No matter how much pain, no matter how much suffering, Izuku couldn't let himself lose. He knew that it was his destiny to fulfill his dream, and he wasn't going to let some demon stop him from achieving it. A smile creeped its way onto the transformed Izuku's face and he yelled.
"I WILL BECOME THE WORLD'S GREATEST HERO"
Izuku's determination proved too much for the demon champion to handle, and he was forced to relinquish control of Izuku's body.
Then, Izuku collapsed.
So that was my first attempt, hopefully it's not that bad. If anybody has any suggestions I am very open to constructive criticism and I'm always looking for a chance to better myself and my writing. This chapter was mostly setup, so not too much happened. The next chapter will explain a bit more and obviously go into what happens after Izuku's first transformation into his demon form. Also for the demon form it looks pretty much exactly like Akira's demon form. Although I might make it change appearance slightly once he gets OFA. Anyway be sure to leave a review and if you enjoyed it favorite the story it helps out a lot.
Also big shoutout to my boy SeaBloople for helping me fix my garbage writing and just being an absolute lad. Check out his fic Twice: Venom and Jin if he ever decides to fucking update that shit. Nah but seriously check him out he's a pretty damn good writer.
