[Brattification, Corruption]



Villainy was not an easy job. Not with all the heroes that were on the rise, trying to rat and snuff them all out. At least, that’s what the seniors in the community thought, the ones that had been at this for longer than most could remember.



One of those villains that needed a fresh breath of air was the man known by his quirk name, Gaslight. Affectionately named ‘Daddy Gaslight’ by his peers, he was a man that could best be described as overweight and out of touch. After all, it was a long time since the common man had accepted him as part of society. But that was fine. He liked it more when he was an outcast.



Ever since all those heroes started worming their way in, taking out his poker partners and leaving him with dull friday nights? He started wondering if there wasn’t a way to turn all of this growth around on the goodie-two-shoes of society. Something that could benefit a man like him. Something that would let him get one over the lot of them.



It was then that his pea-sized villain brain finally started sparking and cooking together a scheme that would make even the greatest supervillain blush. A scheme that struck at the heart of heroism, one that would spell doom for the future…



After all, what better way to deal with heroes than to nip them in the bud and make them much better. Take the youth of today, and turn them into villains! It was the perfect plan, and he knew exactly how to pull it off thanks to a tip from one of the younger villains that he had gotten all cushy and cozy with…



Now, he just needed to wait for his chance to strike.

“Momo! Toss one over!”



Two young heroines were out late at night inside a forest that served as a training ground for young heroes that wanted to train their abilities. A place that had previously been attacked by villains, but nobody would be stupid enough to attack it twice knowing what could happen.



“Are you sure you’re ready for this, Jirou?” The black-haired girl wearing an outfit that exposed her midriff asked, slowly drumming her fingers along her thigh. She knew that her friend was capable, but if something went wrong…



Her friend, a girl wearing what basically amounted to a punk’s jacket and pants, grinned a little as her extended earlobes wriggled around in the air. “Trust me, I’ve got it! Just toss it over!”



Kyoka Jirou and Momo Yaoyorozu. Two of the bright minds that were studying at U.A. And the targets of tonight’s hunt, as a pair of eyes slowly leered their way out of one of the bushes…



“If you say so. Careful now, or it just might hit you.” Momo said as she used her quirk, a simple knife popping out from her midriff as she primed it for a throw.



The blade flew through the air at astounding speeds, courtesy of the black-haired girl’s well-trained arm, only to stop in mid air…



Courtesy of the soundwaves that came from the amplifiers on the other girl’s wrists, the vibrations being powerful enough to catch something right out of the air.



“See? What’d I tell you?” Jirou grinned as the blade snapped in two, falling to the ground right as she unplugged her earlobes from her amplifiers. “I trained hard to make this work, you gotta have a bit more faith in me!”



Momo chuckled a little as she stepped closer to her friend, nodding and bowing slightly. “I’m sorry for doubting you, Jirou. I just didn’t want you to get hurt.” She formally apologized, honesty pouring off her lips.



This made her friend blush, the punk-like girl slowly scratching her cheek. “E-Ehe, I guess that’s as good a reason to be worried as one can have…” She muttered. Every time she thought she knew the girl, she had a way of sneaking up on her and embarrassing her somehow…



“Well well, what’s a couple of cuties like you doing out here in the middle of the night? Don't you know it’s way past your bedtime?”



Both of the students turned towards the voice as an older looking man came out of one of the bushes, his very presence causing them to grow cautious. Nobody was supposed to know that they were out training like this, much less a stranger…



“Excuse me.” Momo said, her eyes remaining vigilant as she stepped a little closer. “This is private property, sir. Please leave, before we call the police.” Despite everything, the man hadn’t shown himself to be dangerous. Not yet. So she followed proper protocol…



Unfortunately, he was much more dangerous than he seemed, as he quickly grabbed the young girl by the arm and pulled her close. “Oh. I’m very much allowed to be here. I’m sorry that you didn’t know, but Daddy has a personal pass to every place in town.” He chimed, his thick arms practically pinning her against his gut.



“Let her go, you creep!” Jirou shouted as she primed her bracelets, the speakers that would allow her heartbeat to ring out and attack those that dared stand in her way. And considering that man was going to hurt her friend..!



Momo initially started struggling, but  the words that ran through her head sounded convincing. Though, the fact that he called himself ‘Daddy’ was enough to keep her on edge. “L-Let me go..!” She cried out, her body letting her know that his grip was nearly crushing it…



“Aw, why would I let go of my little sweetheart?” ‘Daddy’ giggled as he planted a kiss on the black-haired girl’s cheek, the saliva on his lips leaking its way onto her face as it slowly seemed to sink in…



The words that he spoke were bouncing around inside the young girl’s mind, slowly and surely worming their way around her brain as they did their best to choke out her thoughts. The good parts of her soul, the heroic parts that knew that all of this was wrong, were crying out with every moment that passed by.



Momo gasped and panted as she slowly started rubbing up against the older man, giggling. Something about his body was getting a lot nicer as she spent time brushing up against it. The warmth radiating off him, the safety of his arms. Daddy was nice, wasn’t he? That’s what her mind was telling her, and…



“That’s the ticket. My little Brat, looking as precious as ever.” ‘Daddy’ giggled, as he let go of her. “But I’m sure you want to do more than just tell your Daddy that you’re having a good time. Don’t you?”



Jirou watched with mild horror as the girl in front of her, the girl that she had just been practicing with, started to shift thanks to the words that had left the man’s mouth. Though he had him practically dead to rights thanks to the potency of her heartbeat, the shock of what was happening left her unable to pull the proverbial trigger.



Momo giggled more and more as her outfit soon changed into something that could only be called excessively erotic. A skirt that didn’t cover anything, a thin thong that flossed her fat asscheeks, and a tube top with ‘BRAT’ written using small jewels across her bosom. Not only that, but her eyes had gotten a little sharper as she turned towards the girl she considered a ‘friend’ just moments ago…



“Of course, Daddy! I’ve been wanting to have a hero pinned between my thighs!” The newly christened brat licked her lips as she spawned a pair of weapons from her tummy, two nail-filled bats that a girl like her would’ve never been seen brandishing before. But now that her heart was villainous and bratty, just like the older man had been saying it was, it felt right!



Jirou grit her teeth a little as she jumped out of the way of her former friend’s incoming swing. “Come to your senses, Momo! This isn’t you! You’re not like this!” The young heroine cried out, her feelings for her friend preventing her from shooting directly at the girl.



“Eeehhhh? Why wouldn’t I be like this?” Momo giggled as she tossed the bats away just as quickly as she spawned them, utterly bored of them as she pulled out a pair of swords instead. “It’s fun causing mayhem!”



Another sword flew towards the heartbeat-wielding girl, and she used her sound to shatter it as soon as it got close. Just like she had practiced. “It’s not fun, Momo! It’s bad! Really bad! You’d never do anything bad!”



“Of course she would. That’s who she’s always been.” A voice echoed through her ears, prompting her to look back and straight into the eyes of the man that had transformed her friend into a brat, prompting her to quickly jump away. “Aw, you don’t want a hug from Daddy? What a shame, I’m sure you’d love one.”



Jirou aimed both of her hands towards the Villain. “Who are you anyway!? What’d you do to her!? Tell me!” She shouted, unaware of the girl sneaking right up behind her.



“He’s Daddy, you silly girl!”



The punk-like heroine didn’t get a chance to turn around before a kick found its way to her back, launching her into the older man’s arms as he quickly hugged her tight, pinning him against the same belly that had been comforting the brattified heroine just moments prior.



“Ahaha, there we are. What a good girl you are, Momo.” The older man smiled and winked to his ‘daughter’, who bashfully giggled herself. “Now, to answer your questions, little lady…”



Jirou tried to struggle against his arms, but they were too strong. Or was she too weak? She did just get called a little lady, and she did feel a bit smaller…



“You may call me Daddy Gaslight. That’s a fine name, rolls right off the tongue.” The older man explained, while kneeling down and keeping his arms tightly wrapped around the girl. “As for what I did to her, nothing special. Just the same I’ll do to you, my dearest little Brat.”



The last word rolled off his tongue so hard that it nearly smacked the girl right in the face, causing her to convulse as she tried to back away. Not that she could, considering how tightly he held her against him.



Jirou’s mind was unravelling thanks to the word as it slowly sank into her head. Gradually making it the lone truth about her, as everything about her changed as a result.



Her clothes tore themselves apart and remodeled themselves into something much more degrading. Something free that a brat would wear. A torn tube top that barely covered up her tits, with one nipple even poking through the holes. Her shorts had gotten much shorter and struggled to contain her fatter ass, which bounced with every breath she took.



It wasn’t just her ass having grown bigger that was the problem, it was the writing splayed out on both cheeks. ‘BRAT BITCH’ in capital bold letters that had been woven into the fabric, only barely visible as her ass tried to peek out over the waistband and expose the thong riding between her cheeks.



As Jirou slowly took a breath, the brattiness inside her head having fully taken root, she giggled and slapped her old man on the cheek. “Daddy, you stink!” She laughed, taking a big whiff of his manly scent as she wrapped her arms around him.



Momo joined her, giggling as she hugged her old man as well. “Yeah, he might stink, but Daddy’s our Daddy!” The tit-focused brat grinned, pushing those very same melons into the man that had turned her into a mockery of what she once was.



“That’s right. I’m yours, just like you’re mine. Now how about we go get something to eat? I’m thinking you two deserve a little snack.” Daddy Gaslight chimed, and both of his girl drooled in response.



Just like that, he had begun to unravel the foundation leading to new heroes… And he got a couple of cute daughters in the process. What a wonderful plan it had been...
