Requested by @Elinnaris13]

"Quit yelling, Kacchan," a voice sighed from the shadows. The voice was familiar in a way that ground on Bakugo's nerves, but it was the nickname that tipped him off to who was speaking.

"Deku? What the fuck are you doing here?" he demanded, enraged. "Don't tell me you think you're gonna save me! You couldn't do shit against that fucking sludge asshole, don't think for a second you can do shit now."

"Oh, you're so full of it Kacchan," the voice echoed against the walls ever so slightly, enough to add an eerie effect that made Bakugo's spine tingle unpleasantly. "Has it ever occurred to you that you might not be the center of the universe? That maybe, just maybe, it's not the gravitational pull of your supermassive ego that keeps the planet spinning? That I'm here because I belong here, and not because of some messed up childhood loyalty to you?"

"The hell's that supposed to mean?"

"It means you were right all along Kacchan," Deku stepped out of the shadows and into the dim light. He looked like he always looked, but also not quite.

His dumb t-shirt was black instead of white, and it had the words "three piece suit" on it. There was a gas mask hanging around his neck. He looked a little paler than Bakugo remembered with dark bags under his eyes. The biggest difference however, was his expression. He remembered Deku as a blubbering coward, but an expressive son of a bitch.

"I was never meant to be a hero." Deku's expression was all but dead as he stared at his childhood friend with empty eyes. "You're in my house now."

Bakugo's chest boiled up with anger. Sparks flew from his hands. Curses frothed from his mouth as if he were a rabid animal, but he said nothing of substance. He couldn't think of anything but his useless, quirkless, childhood friend standing in front of him, unfazed, while he was locked down tight, trapped.

"If you've run out of breath now, can someone hit the lights?" Deku asked. "It was fun for dramatic purposes, but nobody can be expected to see with it like this." A loud clang resounded, followed by the faint buzz of electricity as the lights came on and illuminated the room. "Much better."

Bakugo blinked until his eyes adjusted to the harsh fluorescents. Finally, he could take a good look around the room, where he saw all of his classmates, similarly bound as he was, eighteen in all. Bakugo had been nabbed in his sleep, he could only assume the rest had been taken the same way. They'd all just returned from a brutal training camp, so of course they were exhausted, but Bakugo felt like kicking himself. How had they all been so careless as to get captured? And by Deku of all people!

Well it wasn't just Deku. The whole League of Villains was at fault, the same people who had broken into the USJ planning to kill All Might, the same people who supported Stain, the hero killer that put their class rep six feet under. One of 'em was standing by the light switch, a girl in a sailor uniform that Bakugo didn't recognize.

"Didn't I tell you it would be more fun if you spoke up first Izuku?" The girl giggled. "He's got an ugly face, but he sure is funny when you pull the rug out from under him like that, huh? You hear him curse haha!"

"I gotta say, Himiko, it was pretty satisfying," Deku said, the slightest hint of a smirk on his face as he addressed the girl.

"Um, do you know this guy, Bakugo?" Round face asked, and he sneered at her.

"I used to," he spat. "You don't have to worry about this quirkless bastard though. He's not a threat."

"Well, it's true that I don't have a quirk," Deku said, "but I wouldn't say I'm not a threat. After all, it was my plan that got you all here, and that's no small feat. Wouldn't you agree, Himiko?" The girl giggled. "Shigaraki wanted to have the Vanguard Action Squad attack you all during your training camp, but I thought that having nine people attack all thirty-six hero students, as well as six pros probably wouldn't go down without losses on both sides. On the other hand, snatching you all out of your beds the day after, when you're exhausted and not under any sort of supervision..."

The door slammed open and in walked that crusty-handy-bitch from the USJ, accompanied by a discount-teenage-mutant-ninja-turtle, the smoky warp quirk guy, a creepy magician looking fucker in a long coat and a top hat, a large person who could have been a woman or maybe a man or maybe both or neither, fuck if he knew. 

"Yes we're all very proud of you Midoriya." Handjob said, his gravely voice dripping with sarcasm. "But I'm still the one in charge here, and I was supposed to talk to them first." Deku rolled his eyes, but took a few steps to stand by the girl in the sailor uniform. "We didn't really need all of them," he sneered.

"Nah, I think it's better this way," a new voice said as a new person strolled into the room with his hands in his pockets. The man had black hair and a patchwork face and he was almost as ugly as Handjob. "No loose ends when we've got 'em all, no risk of a half-cocked, suicidal rescue attempt from a bunch of fifteen-year-olds with hero complexes and no sense of self preservation."

"Is Midoriya in there?" came a higher voice from outside.

"Yeah," the burned guy responded.

"I thought we weren't supposed to come in here yet," remarked the same voice as what appeared to be a middle schooler walked in wearing a full-face gas mask and helmet.

"You're not!" Handjob barked, scratching at his neck irritably. "Now all of you, get out. You'll have your chance. Except you Kurogiri, you can stay." The rest of the villains groaned and filed out of the room.

Once they were gone, Handjob gave them his whole stupid speech about their cause, and why heroes were a bunch of assholes, and that the league of villains was going to tear everything down. Then when he was done spouting bullshit, he said he wanted Bakugo to join them, and anyone else too, while he had them there. Bakugo laughed in his crusty face.

Handjob growled, then leaned uncomfortably close to Bakugo and said, "You'll come around. It's not like we don't have plenty of time."

Then he cackled as he walked out along with his warp lackey, and in walked the lizard, the masked magician, and the henchperson of indeterminate gender, who must've been on guard duty, though they mostly stood in the corner chatting quietly, and not paying very much attention to the hero-hopefuls.

"So... Bakugo..."

"The hell do you want round face?" he snapped.

"How did you used to know that guy?" she asked hesitantly. "You called him Deku? Right?"

"What's with all the fuckin' questions, hah?"

"In case you hadn't noticed your old friend just kidnapped all of us!" Kirishima pointed out. "So I think we have a right to know who he is."

"Like hell! And he's not my damn friend!"

"Bakugo, it would be helpful to know anything we can about our captors," Ponytail girl said gently. He just glared for a long time, looking at a bunch of his classmates, and seeing variations on the same confused and determined expression.

"What fucking good's it gonna be when they're standing right the fuck there!"

His classmates weren't quiet after that as he'd hoped they would be. Anyone could sense how on edge they were, but their guards didn't seem to mind them talking really, so they talked just to keep from freaking out. The little grape bitch made some frankly disgusting comments about the villain in the sailor uniform to which Raccoon eyes, Soy sauce, and Kirishima responded with exaggerated gagging noises.

One at a time, they were escorted out of the room to eat and use the restroom—if being shrunk into a marble counts as being escorted, that is. Bakugo tried to escape while they were feeding him, but he got turned into a marble and woke up back in the room without even eating.

A few hours later, the villains swapped out with three others, a massive motherfucker with a prosthetic eye, who was built like a brick shithouse, and a guy wearing a grey and black mask that covered his whole head and a black body suit who was clearly insane, and who clearly annoyed the shit out of the bigger dude.

The big dude didn't seem too keen on letting them talk, but the one with the mask tried to strike up a few utterly confusing conversations with a couple of them, despite the big dude's complaints.

The next shift was Deku, the girl with the sailor uniform, and the little gas-mask-wearing twerp, and as soon as they walked in, Bakugo's classmates looked at him severely. Deku followed their gaze.

"Let me guess: you've been stubborn as always?" It didn't sound as much like a question as it did a passive aggressive complaint.

"Shut the fuck up, Deku!"

"You were right. This guy's a jerk," the gas-mask twerp said.

"Always has been." Deku sighed again and Bakugo desperately wanted to blast his creepy face off.

"Seriously, who is this guy, Bakugo?" Kirishima asked, scowling with anger and exasperation, and probably feeling like crap about not being able to do anything even though they were all in the same boat.

"Fuckin' fine," he griped, and he glared at the ground. "We went to elementary school together, and then middle school. He's a damn nerd, and the biggest damn hero fanboy you can imagine. Guy's room was practically wallpapered in All Might posters, and he was constantly muttering about heroes and shit. He was fucking annoying."

"I was annoying," Deku repeated blandly. "That's really what you thought of me, isn't it? I was annoying, so you beat me up, crushed my dreams, destroyed my property, and told me to jump off a roof. You know if I had, you would have gone to jail for inciting a suicide. You know that's a crime, don't you Kacchan?"

"You did what?" Bakugo couldn't tell exactly who said it. It sounded like multiple people, probably, but he was staring at the ground, and all he could really think about was the feeling of something cold and slimy crawling around on the inside of his sternum.

"But I was annoying, so I guess that would've been fine with you."

"How could a scumbag like you ever be a hero?" sneered the boy with the gas mask.

"Well, given Dabi, I guess he's not the only one," said the girl in the sailor uniform thoughtfully.

"Now that's a nice metaphor," Deku said. "Katsuki Bakugo, the new Endeavor, a hero who creates villains, destined to play second fiddle his whole career."

Bakugo was silent after that, his classmates were too for a while, but eventually they got bored or something and started talking again. The villains didn't seem to mind. Gas-mask kid had pulled out a deck of cards at some point, and they played a few rounds before the girl remarked that she wished she could bloody some of them up a bit.

"What's the girl with the bob and the pink cheeks again, Izuku?" she asked.

"Ochaco Uraraka, antigravity quirk, needs all her fingers to use it, so we've bandaged her pinkies for now, but if need be we can cut them off," he mumbled absently, and drew a card.

"Now that one would look really cute with a little blood on her," she said, pulling a knife out of her sweater sleeves and twirling it in her fingers. "Just a little scratch on her cheek, maybe the temple."

"We're not supposed to hurt them Himiko," Deku said with a frown. "Not yet anyway."

"What about the boy with the scar on his face?" she asked. "What's his name?"

"Shoto Todoroki, son of Endeavor, ice and fire quirks but we got some suppressants on the black market for him along with some of the others, so he won't be doing anything much. He's also on the don't touch list," Deku said. "So hands and knives off."

"But he's got so much potential with that pretty red scar of his," she whined. "I would only have to rough him up a little bit. It probably wouldn't even hurt him that much."

"Isn't he pretty enough without being drenched in blood?" 

"But Izukuuu~"

"Even I know that kid's got too much potential to waste just cause you've got a thing for blood, Toga," the gas mask kid said.

"Huh? What's that mean?" she asked.

"We're trying to get them on our side, aren't we?" he told her. "Endeavor already produced one villain, so this one's practically a shoe-in, isn't he?"

"I guess," she said, then looked at half-and-half with a sigh. "Maybe some other time."

"What are you taalking aboout?" Half-and-half asked in a voice that was irritatingly calm, but a little slurred, probably because of the drugs they had him on. "What villainn did my fatherr produuce?"

"Should we tell him Izu?" the girl asked.

"I think we should let Dabi do it," gas-mask kid said, putting down a card.

"I agree with Mustard." Deku put his hand of cards face up on the floor. "I win."

"Not fair! I got distracted!" the girl complained, and the kid in the mask just groaned in frustration. Bakugo couldn't even tell what game they were playing, but somehow he felt like Deku had cheated. He felt like Deku had cheated in real life too, but he knew that it was all his fault anyway.

The conversation moved on until the little grape bitch made another pervy comment about the girl in the sailor uniform and before Kirishima and the others had a chance to gag again there was a loud bang, and Bakugo's head jerked up to see Deku pointing a gun at the grape's head executioner style, and blood all over the place, not only was there a gaping hole in the little bastard's forehead, but Pikachu and the octopus looking dude, who were on either side of him, had blood splatter all over their legs.

Pikachu looked like he might faint, the rest of the class stared in horror. Deku handed the gun to the gas-mask kid, who put it in a hidden holster that Bakugo hadn't noticed before. When had Deku become so cold-blooded?

"What happened to not harming the prisoners?" the kid said as he pulled his jacket over the gun holster to hide it again.

"Minoru Mineta, uncomfortable quirk, uncomfortable personality, not on the list of prisoners we're not allowed to hurt."

"Fair enough." Gas-mask shrugged and scooped up the cards they were playing with. "Another round then?"

"What the FUCK Deku!" Bakugo blurted out. "You fucking killed him! What the fuck!"

"I don't want to hear that from you of all people." Deku turned to look at him and took a few steps closer, casual as you please. "You threaten to kill people all the time, but now that I've done it, it's not okay with you anymore? Did I make it uncool?"

"Holyshitholyshitholyshitholyshit HOLY SHIT Bakugo, what the hell kinda childhood friend do you have‽" Pikachu screeched in utter horror, staring down at the blood soaking through his sweatpants.

"We were never really friends," Deku frowned disinterestedly. "I was, what was it you called me? 'Not even a stepping stone, just a pebble on the side of the path', or something like that."

"Will your leader really be okay with you killing one of us?" the invisible girl asked desperately. "Don't you think you might get in trouble?"

"Probably not," said the girl in the sailor uniform, and she wrapped her arm around Deku's neck like they were besties. "But Izuku's been nudging out Tomura to be the boss' favorite. Besides, nobody liked the little purple guy anyway, not even that much blood can save his face."

She detached herself from Deku and wandered over to Pikachu. She licked a drop of blood off his face and Bakugo could see him squirming from across the room. "It looks very good on you though."

"Please go away," he whimpered. "I'm very sorry, but I'm not really into psychopaths." He sounded like he was on the verge of a panic attack.

"Well suit yourself, but you'll all turn eventually." She stepped away with a twirl on her heel and giggled again. "I'm up for another round, Mustard, deal me in."

—

It's over a week before they're rescued. Some of the villains get taken in, but not all of them. Deku's long gone, and so are the other two he was all buddy buddy with, Mustard and Himiko Toga, as is Shigaraki, and Dabi, whom they discovered was actually half-and-half's older brother Touya that everyone thought was dead. So Bakugo's far from the only one who's messed up by the experience.

"Hey, Bakugo? Are you okay?" Kirishima asks him while they're at the police station, waiting for their families to come get them. "I mean, obviously you're not okay, none of us are, but... Bakugo?"

"No! I'm not fucking okay, Kirishima!"

Bakugo's breathing is hard and heavy. The paramedics had given them all shock blankets, but he'd resolutely refused to take his. He regrets that now, though he'll never admit it, because he wants nothing more than to wrap himself up and disappear forever, and he's never felt like this before. He feels the weight of Kirishima's hand on his back, and can't bring himself to push it away.

"Deku wanted to be a hero," he forces out in a hoarse, quiet voice. "He couldn't hurt anybody before... and now he's a villain, and he killed..." In the end, four of their classmates had been killed, three of them by Deku, for being too annoying, or not worth the effort of keeping them alive, or whatever excuse he made up to fire that damn gun of his in the face of a fucking child. "And it's all my fault."

"It's not your fault," Kirishima says, rubbing his hand against Bakugo's back, but they both know it's not true. At least, that's what Bakugo thinks.

"Except it fucking is my fault," he croaks, but he stubbornly refuses to cry. "I'm the reason he became like that. I'm the reason they're dead. I made him like that, and there's nothing I can do to fix it, or change it. There's nothing."

Bakugo swears he won't cry.

By the time he climbs into the car with his parents and they start to drive home, he's already hopelessly sobbing.

[Did somebody order some ANGST? Technically, no, but you didn't really give me a genre, and I don't know how you could possibly, realistically have expected me to take a prompt like this in any other direction. Love y'all.
