Chapter Text
It came unexpectedly, the Dawn of Quirks. Suddenly people were manifesting strange abilities once thought only possible in fiction. The world was in chaos for the longest time until it reached a new age, The Age of Heroes. Now people were using their Quirks for the betterment of society, protecting people from those who would use their powers for evil, the Villains. Heroes became one of the most sought after careers almost over night and now every kid dreams of the day they can earn their license and use their Quirks to join their ranks. One such kid is the focal point of this story, Izuku Midoriya. Izuku loves heroes, he loves Quirks and longs for the day he can be one himself. Unfortunately there's an issue. While about 80 percent of the population have Quirks, that still leaves 20 percent without them and he's among the latter. Everyone says being a Quirkless hero is impossible, his teachers, his classmates, Kacchan (Katsuki Bakugou), even his mom, though he knows that's mostly out of worry and she'd support him if he tried. But he won't let that stop him. He's going to show everyone that he can be a hero!
Smash cut to a depressed Izuku walking home after the day that managed to top his Quirkless diagnosis as the worst day of his life. It started out normally, he was bullied at school and the teachers didn't care, even revealing that he wanted to go to UA for no reason other than wanting to put a target on his back and he had a negative encounter with Kacchan (how would he feel if he actually jumped off the roof? Would he even care?). The day got interesting when he was attacked by a Sludge Villain, and even more so when he was saved by All Might himself. After an admittedly reckless stunt when he latched onto the man as he jumped away and an unexpected reveal of his weakened form, Izuku took the opportunity to finally ask the number one hero the question burning in his soul, could he be a hero without a Quirk.
"I'm sorry to say it but no. You can't be a hero without a Quirk." The blond man had denied.
After ten years, he finally got the answer, and it was the same as everyone else. Why did he assume it would be any different? This was All Might, the man who could change the weather with a punch, of course he'd say a Quirk was needed! Feeling like an idiot, the greenette made his way into his apartment and was met by his mother.
"Izuku! Baby are you ok? You're all scuffed up?" Inko Midoriya asked worriedly.
"I'm fine mom. Just an accident on my walk." He mumbled.
Inko was concerned. She's only seen her boy so down once before and she couldn't bare to see it again.
"As long as you're ok. How about I make your favorite Katsudon for dinner?" She asked.
"I'm not hungry. I'm just going to bed." He said which only made the worry worse. He'd never turned down her Katsudon before.
Izuku stopped just outside his room. He knew what awaited him inside. A veritable shrine of All Might merchandise, all mocking him. He didn't want to enter but knew they'd be more questions if he didn't so the boy toughed it out and went in. It felt as bad as he anticipated but he was quick to turn off the light and try to get some sleep so he could ignore it.
The next day he barely had any energy. He dodged his mom's attempt to ask more questions as he quickly left the house to get to school. It was same old same old there but he couldn't find it in him to care. The bullies eventually got bored of his lack of reaction and left him alone. Except one.
"Oi Deku, you're still fucking here?" Katsuki Bakugou sneered at him.
"Leave me alone Kacchan." Izuku said quietly.
Small pops from the other boy's palm, a sign of his Explosion Quirk, went off. "The fuck you say to me?! I don't know where you got the balls to think a shitty Deku like you could tell me what to do but I do know you better watch it!" He threatened at his only volume, loud.
Normally he'd be intimidated but he just didn't have it in him. "Please Kacchan, not today." He begged.
Katsuki pushed him against a wall, causing his hero analysis notebook to fall to the ground. He looked around and saw people watching, clearly enjoying the show, and scoffed internally. And they claim to want to be heroes.
"I decide what I do and what day I do it, and I've decided you didn't get it through your thick skull yesterday, so let me remind you." The ash blonde said, picking up the new notebook and exploding it like the previous one. "You're nothing Deku, and you should stay down there where you belong."
As the students and some of the staff laughed at him, something shifted. Izuku Midoriya is not an angry person. Sure he's been mad before, everyone has, but he strives to take life on with a smile like All Might. But right now, all he knows is Rage. At the school, at Katsuki, at All Might, and at himself.
"Shut up." He said quietly, eyes on the ground.
"Hmm, the fuck was that?" Katsuki asked.
The Explosion user had to take a step back when he raised his eyes to him, the sheer fury looking off on his face. His eyes began to glow a menacing green, energy firing off him uncontained.
"I said, SHUT UP!" The greenette yelled, the energy flying off him as he stood.
Everyone in Aldera Middle School watched in awe and more than a little fear as the boy's anger flared.
"What the fuck? Since when can the nerd do this?" Katsuki asked.
Izuku didn't hear him though. Everything was too loud. He couldn't think straight. Couldn't focus. He was so angry and didn't know what to do with it. Until his eyes locked on Bakugou's once more. Now his body and the energy it was producing screamed at him to do one thing. Attack. And he did.
Katsuki was unprepared for the speed at which the nerd moved until he was right in front of him. A vicious left hook sent the boy back and the school into a frenzy as people began to run out. It was still too loud for the greenette.
"DEKU!" Katsuki yelled, rocketing at him to hit him with a point blank explosion to send him through a window. The boy stood, having taken far less damage than he should have, pupil less green glaring at raging red. "You think cheap shots can stop me!" He screamed.
They had definitely drawn public attention, people were wondering if this was a villain attack and heroes would be here soon but he didn't care. Izuku growled and lunged at Katsuki who was more than ready to meet him. An explosion was fired but in a surprising display of agility his target jumped over him and kicked him in the back and onto the street. A follow up lunge to the spot the ash blonde landed would have done real damage if he hadn't rolled out of the way, leaving the pavement the only thing cracked.
Some nearby heroes had arrived on scene.
"What's going on?" Death Arms asked.
"Don't know, but we have to stop it." Kamui Woods stated. His Lacquered Chain Prison moves to ensnare the two boys but an explosion from Bakugou accidentally burned some of it while Midoriya was trying to rush him. The explosion did blast him away but he was quick to recover.
Kamui withdrew his wood with a hiss. "Of course one of them has such a Quirk." He complained.
"I got this." Death Arms told him. The man ran at Izuku, who did not appreciate his appearance.
"Out of my way." He hissed at the hero, moving at high speed towards the man who wasn't expecting the kid to be so fast and got punched back for his efforts.
"Crap, he hits hard." He said.
The ground shook as another hero showed up. Mount Lady tried to swat at Izuku, the boy avoiding the hit to run up her arm. She shook him off, accidentally sending him flying into the school. He got up again, albeit shakily and they could almost feel the force of his glare.
"What's this kid made of?" Mount Lady asked.
Izuku took a step, the heroes bracing for the attack, before the energy faded and he collapsed. A sigh of relief was breathed by everyone present, except for Bakugou. He had too many questions, what was that, since when did Deku have a Quirk, and why was he actually afraid of him for a second.
All the while the greenette slept, unaware of the world around him.
