    Summary


    Izuku is scary. Admittedly, his smiles are bright and his eyes are pretty; his freckles catch sunlight with gilded warmth, and everything about him is oh-so kind.

    But then he has this mindset, one that follows him through spars and training exercises and villain attacks, one where every line of his body is raw determination, exposed nerve endings and supernova energy. But more intimidating than the sparks of lightning or even than his sheer strength and speed, are his eyes.

    Because they glow.

     
    (I definitely deviated from the original prompt a lil' bit in some ways, but I think this should still fit the bill!)

    Summary

    Hitoshi runs into a recently escaped Eri at probably the worst and best time imaginable, (he was having a crisis of his own before the little girl almost took his legs out when she crashed into him).

    But by saving Eri he triggers a butterfly effect that sets him on a very unorthodox path that lands him in the hero course, in class 1-A nonetheless.

    While this is a dream finally realized, it also means being in a class with a guy whose father threw his parents in prison 7 years ago, (though he doesn't blame Endeavor his parents were terrifying cult leaders).

    But it’s not like it matters in the end, he isn't going to waste his time making friends when he's already so far behind everyone else.

    However, if Izuku keeps staring at him like he's some limited-edition All-Might figurine he won't be able to convince himself that his heart doesn't flutter in his chest every time the green-haired boy opens his mouth or when he shares his food or invites him to study or...you get the point.

    Maybe if he convinces Izuku that he can't be befriended, then Shoto will stop looking at him like he knows something Hitoshi doesn't.

    Summary

    This lightening made it look like the gods were angry, instead of joyful, and loud, and vibrant. And although meeting the gods face to face in a duel of power was probably up there somewhere in the top 10 of his unmade bucket list, meeting an angry one wasn't, no matter the absolute bragging rights that would entail. And that's because dying wasn't really in his planner for this year to begin with- but his homework for next week wasn't either, so maybe that was just more on him and his crippling lack of organization skills.

    Summary

    Katsuki didn't like that she didn't have that much faith in him. That she didn't believe that he'd become as great as his idol one day, number one. It made him angry-that his mother wasn't as sure of him because of his subgender. Perhaps it's because she'd hardly ever seen an omega like him, or even one that had a drive like him. But it hurt, he didn't like that he'd even be hurt because his mother didn't believe him to be as driven as her to get what he wants. That she believes that their society didn't really believe omegas could be great powerhouses.

    He'd show her. He'd show them all.

    He'll be the best no questions.

     

    Bakugou Katsuki always keeps his fucking word.

    Summary

    “My hip is dislocated.”

    Dabi blinked once. Twice.

    He laughed in that sinister way that always made Hawks’ feathers stand on end. “Try again, birdie.” The scarred man huffed, unamused. “You think I’m an idiot?”

    Hawks sputtered in disbelief. “You think I’m lying?”

    “I think you’re full of shit.” The villain said.

    Or, Hawks accidentally injures himself minutes before a meeting with the LoV.

    Summary

    Aizawa has always had a soft spot for cats, and so have Eri and Shinso since they've come to live with him and Hizashi. Even if the latter isn't always pleased with how many cats they have managed to accumulate, he also has a soft spot for his family, but recently he's come to the conclusion that enough is enough when it comes to his husband's habit of taking in strays. After all, seven cats is far too many to sustainably exist in their apartment, but what happens when Aizawa can't help but take in his newest rescue might have him re-thinking that line of logic...

    Summary

    ...do you remember the beach?

    "I-- I'm going to tell you a story, my boy..."

    I clutched the emaciated side of my stomach, a bright concentric scar bandaged with the smiles I'd built up over the years. But it was okay... for my boy was here. The jade green fluff of his hair reminded me of his mother's. It was beautiful. It were the small things in life that'd gotten me this far. Yes. On that day, that could've been the end. But-- I was given a 2nd chance. Yes, I was given a 2nd chance after all. To tell this story to my boy-- to anyone willing to listen. A... Legume Lullaby, if anything...

    "All Mighto, what's wrong?"

    My dinky Shounen always knew how to cheer me up as I cradled the minuscule span of his body, quaint and all, in the span of my twig-like arms upon the comfort of my bed. But even then... it was time to tell my story.

    "You see my boy... I'm going to tell you how... I really lost my stomach."

    That day-- That day... It was all my fault, wasn't it? I remember the beach, Oshio. I remember the beach, Mista...

    Summary

    The raven-haired man pushed the door open, then stepped to the side to let them in. The person that came in was none other than the number-two pro hero, Hawks, dressed in his costume’s aviator jacket, though his iconic visor and headphones were missing. Izuku noticed after a closer look that he was wearing regular clothes beneath the jacket- a pair of khakis and a black shirt with a rainbow zebra on the front- and, more importantly, that he was strangely half a meter shorter than he should be. Confused, the student leaned forward in his seat, peering over the rows of desks blocking his view, until he was able to see the colorful wheelchair the hero was sitting in.

    “Hey, Eraser!” Hawks greeted with a smile as he wheeled himself further into the room, moving out of the way so the other man could close the door. “Sorry if I’m early, it’s been a while since I went out with this. I didn’t want to be late.” He said, motioning to the chair.

    You're a successful Hero but anxiety has ruled most of your life. It's kept you alone. It's kept you restless. Maybe talking to that scraggly, blond-haired man will help you grow as a Hero and as a person.

    I'll add tags as I go. This will get explicit in the future.

    Summary

    "That doesn't answer my question," she interrupted him, her gaze sharp and scrutinizing. "Why did you help him?" 

    The smell of hospital antiseptic was painfully familiar, and it reminded him of the truth. 

    "My brother is - was - the pro-hero, Ingenium," he explained quietly. "And a few months ago - he was attacked. And hospitalized. I…" he swallowed the knot in his throat and stared at a scuff on the floor. "I wondered… what it would have been like. Had I not been allowed to see him. The mere idea caused me pain, and I saw that suffering in Kaminari-kun. I could not let it persist in good conscience." 

    OR

    When Kaminari's sister has a seizure and is hospitalized, he isn't allowed to visit her due to the League of Villains still being at large.

    As someone who has once been in a similar position, Iida considers this to be absolutely unacceptable.
