Work Text:
Izuku is smart, and he knows it.
He knows it in the way students slide money and food to him in exchange for tutoring or some completed homework.
He knows it in the way the halls part for him, heads bowed in respect.
He knows it in the way they fear him, how the halls echo with rumours of a deady advisor, someone who always knows your secrets and isn't afraid to tell them.
Midoriya Izuku is the advisor, puppeting the royals behind the scenes, controlling the country.
The royal in question being Bakugou Katsuki of 3-B, his classmate and childhood friend.
Bakugou will go from explosions of anger to an angel at Izuku's look alone.
He loved it, loved the power that was so easy to attain.
"Kacchan." He seats himself down on the desk of said boy, smiling. "You made sure you passed the practise test, right?"
"Yes, Izuku. I can't slack if I'm going to be a hero."
He nods, showing teeth with his shut eyed grin. "Good!"
"...how did you do?"
"100%!"
Bakugou's head bounces slightly. "Well done."
"Thanks, Kacchan!"
The door opens. "Class, to your seats."
Izuku hops of the desk, taking his time to get to his seat. Class doesn't begin till he's there, nodding that he's ready.
Even the teachers fear him.
--
"Welcome, everyone, to the support course. I'll be your homeroom teacher Maijima. I hope you all passed your safety lessons?"
"Yes! Let us in already!"
Maijima sighs. "Soon, now-"
"Acutally," Izuku steps forward. "I have to leave. 1-A's assessments are beginning soon, and I'd rather not miss them."
"Midoriya, right?"
He nods.
"Nezu told me about you. You can go. Have fun."
"I will." He begins walking away, notebook and pen in hand.
"Why does he get to go?!" The girl from before whines and huffs.
"Because he's a genius, and someone in 1-A is his unlucky pet project."
--
"Kacchan!" The blond goes from slouch to stiff as a board in moments, eyes wide.
"Izuku..you didn't tell me you'd be here."
"It's been a whole year since our last time, you really think I'd miss this?" The greenette pouts, latching onto Bakugou's arm.
"Yo, Bakubro, who's this?"
Izuku holds out a hand, grinning. "Midoriya Izuku! Nice to meet you, Kirishima!"
"How do you know my name?" He shakes the hand hesitantly.
"He knows everything." Bakugou gulps. "He even announced someones whole life and secrets at school and to villains on the second day cause they crossed him on the first..."
"No-one messed with me after that!" He giggles innocently, while the class share horrified looks.
"s-so..why are you here?"
"A couple reasons actually! First, I have to sign off all your costumes so I need to know the power of your quirks and your fighting stules and such. Second, Kacchan's my prince, so I need to make sure he's gotten better since the last test. And finally, Eraser wants me to weigh in on who to expel."
"Wha-how are you qualified to do this?! You're our age!"
"I'm smart."
Aizawa steps out beside him, nodding. "He is. It's terrifying."
"Anyway! Let's begin!" The book opens and the pen clicks, a feral smile forming behind it all.
--
"Ay, Bakubro, I didn't know you were dating! Congrats!" Kirishima shoots a shirtless thumbs up to him in the changing room.
"I'm not dating. And we've known each other a few hours, shitty hair."
"Really? Then why did Midobro call you his prince?"
"It's a dynamics thing. I'm his project."
"Then wouldn't lab rat be better?"
"No." Bakugou sighs. "And unless you want to be a prince project too, stay away from the advisor. He'll make you a good hero, but he might kill you in the process...Though, it might be too late..."
--
"Midoriya!"
Izuku turns to the friendly voice, closing his notebook. "Yagi!"
"How have you been? I didn't know you were coming here."
The boy chuckles. "I've been well! Beat Nezu in some chess so I could get a little extra freedom here. I'm pretty sure I'm his successor now, but oh well. What about you? How's the suit been?"
"It's perfect. So smart to add that buffer so I don't need to be in big form for anything but punching. The doctors expected me to be at 3 hours by now, but thanks to you, I'm at 10." Yagi grins, patting Midoriya's shoulder. "It's a shame you don't want a quirk to go with that brain, or I'd give you mine."
"You know you only need a quirk if you're gonna go pro hero, and I'm not." He chuckles, only to be cut off by loud alarms.
"CODE 3!"
Izuku furrows his brows. "A break-in?"
"It's just a break in." Yagi calls from his spot by the window. "They broke the gate."
"I'm sorry, they what?"
"Broke it? Is something wrong?"
"Yes! No reporters outside have offensive quirks strong enough to break that gate!"
"Oh.."
"I need to tell Nezu."
--
Izuku blinks slowly at the sight of 1-A in their costumes, yet to speak after 5 minutes.
All Might coughs awkwardly behind him. "Midoriya?"
"Right, sorry." He sighs. "I'm just...Hakegure, please tell me you're wearing more than gloves and boots."
"..That'd be a lie."
He begins scribbling in the notebook he'd brought. "I'm going to need some dna if you want a full costume."
"They said-"
"They're idiots. Do you want a full costume?"
"yes.."
"Then I'll need some DNA." He turns to Yaoyorozu. "Did you design that or did you hire someone."
"I hired."
"Are you genuinely comfortable in that?"
"Honestly..no, it's a tad revealing."
"I'll need some of your DNA too then." Another note.
"Uraraka, is that restricting your movement?"
She nods. "I also wanted more of a space theme. Like 13! They're my favourite.!
"Gotcha." He grins. "Iida."
"Yes?"
"No."
"Wh-what?! Why?"
"It's impractical. You can't see properly, it restricts movement, it's got to be hard to beathe in. And your engines could potentially overheat using your normal output."
"But..my theme.."
"You wanna look like Tensei, huh?"
"..yes."
"Okay, I can work with that."
Iida nods.
"Ojiro, we're gonna get you that made of bullet proof materials. Jirou, you're getting a headset that can block sound. Tokoyami, defensive materials. Kaminari, you're getting directional equipment for offense. Todoroki, I'm throwing yours in acid. Shinsou, Hakagure, Todoroki, Iida, and Yaoyorozu, meet me at lunch to go over some ideas.
"The rest of you?" He nods. "Good job."
They all let out a sigh of relief.
"Kacchan, costume still working?"
He does a quick check, doing a full handstand, detatching and re-attaching the gauntlets before he nods. "All good."
"Great!"
--
"Hakagure." Izuku folds his hands on the table, a line behind the sitting girl. "Are you going for overground or underground heroics?"
"Overground."
"Then we'll need something flashy or aesthetically pleasing. Favourite colours and themes?"
"Pastels and cute stuff."
Izuku grins. "Great. Cute can trick opponenets into a false sense of security, but also comforts victims." His pencil flies, then he turns the page to face her. "Lolita style, mostly whites, pastel pinks and purples. Shoes are animal themed sneakers. A hair bow that stays by your ear as a mic for coms. The skirt would be retractable into shorts or pants so you can fight. If you want to go the extra yard, a sword and shield parasol and med kit animal themed purse."
She squeals, bouncing in place, as evidence by the moving uniform. "I love it! But, won't it stop my quirk?"
"Not at all. The use of DNA in your costume would mean it changes with your thoughts and quirk. You'd have to be careful of the mass when it's invisible, but it shouldn't be a problem."
"So cool. Thanks Midoriya!"
"Of course!"
--
"Yaoyorozu." He hums. "Do you want to keep the style you had before? Or completely remake it?"
"Well..with how you're making Hakagure's costume...Could mine potentially be a suit, of sorts."
"With your quirk, we wouldn't be able to do a blazer, but otherwise I can make it happen." He begins sketching. "Midnight's costume material should be useful."
"That thin fabric?"
"I can make it thicker, don't worry. What do you thinkg of this?" He turns the notebook to her.
She smiles, nodding. "It looks amazing."
--
Iida shifts awkwardly as he sits.
"Stop."
He ceases the movement. "Is something wrong?"
"Yes."
"oh."
"look, you're taking on the Iingenuim title, you need to be prepared. If you're visibly scared in front of me, you won't go far."
"I am not scared of you!"
"If you're not afraid, then you should have no trouble telling me off if you don't like the designs, right?"
"I have no issue with that."
"Good." He shows three (3) sheets. "What do you think?"
Iida gulps. "None of them seem quite right."
"What are you gonna do about it?"
"...may I have some scissors?"
"Sure, kid."
Iida takes a deep breath, carefully cutting out peices from all three (3) options efore peicing them together. "This. I want this."
Izuku snaps a picture on his phone. "Well done. I honestly didn't expect you to cut up the work of someone who helped make All Might's costume."
"...what?"
--
"Shouto, Shouto, Shouto. What to do with you."
The boy shrugs. "Just make something that'll upset my father."
"Running off spite, huh?" he chuckles. "You will have to accept your fire eventually." He stands. "Call me when you work our your daddy issues and after you talk to your mom. Then we can talk costumes."
"What?! I just don't get one?!"
"Of course not." He scoffs. "Look, I hate Endewhore just as much as the next person, but I'm not holding back because of it. It's honestly insulting. Not to mention you won't be objective with the costume. I don't deal with brats." He slides some paper across the table. "My number, and your mothers hospital room."
"..."
--
"Costumes, costumes, get your newly improved costumes." Izuku holds out 4 cases for those who needed new costumes. "Yaoyorozu, Iida, Hakagure, and Shinsou."
"Woop!" Hakagure bounces over, yoinking her case. "Thanks!"
"Course."
"We would also like to thank you," Yaoyorozu says as Iida and she take their cases. "As class reps."
"Just doing what I love. Don't worry about it."
Hakagure runs back out, twirling. "I love it!"
Izuku chuckles. "You change fast."
"I had to!"
Kirishima stares. "Isn't it gonna be hard to fight in that?"
"Okay, okay. Are you ready?" She waves her lacy gloved hands about.
"Yes?"
"Okay!" The skirt begins to change itself, gathering up into shorts.
"woah.."
"And! And!" She takes the parasol, presses a button, and grabs onto the top. "Sword and shield!!"
"That's so manly."
"No! It's cute and practical!"
Momo returns, adjusting her black vest.
"What do you think?"
"I like it, but the shirt kept ripping when I put it on."
He nods, writing it down in that notebook. "I'll work on that for next time then, with Mei."
Iida is last. "I thought I wouldn't like it as much as the other but...Honestly, I look very proffessional, like Tensei."
Izuku shoots a thumbs up.
"If you're done fawning over costumes, get on the bus." Aizawa sighs.
"Yes, sensei."
--
"Midoriya, kero."
"Yeah, Tsu?" Izuku looks up from his notes.
"What'syour quirk? We've all been curoius and Bakugou won't tell us, ribbit."
"Oh." He smiles. "I don't have a quirk."
Jaws drop.
"B-but-how?! How are you so smart?!"
"Gotta make up for being quirkless somehow." He shrugs, returning to the paper. "And my mom used to read astrophysics and medical books to me as a kid so I'd sleep and she could study."
Todoroki glares. "You..you're quirkless, and denying me a costume?"
"Yep! Gotta be honest, it's really insulting to only use 1 of 2 quirks when someone with no quirk at all is there. It's like you're saying you're more powerful and I suck straight to my face."
"I see.."
"Oh, btdubs, All Might won't be able to come to this class. There was a costume malfunction."
"Didn't you make it though?" Aizawa tilts his head.
"Yeah..And then Shield tried to update the coding without me! Coding is my thing!"
"..huh.."
--
Izuku's eyes narrow in on the plaza, currently filling with mist. "Why is that so familiar?.."
"Is the exersize staring already?"
"No, those are real villains."
"Aha!" Izuku snaps his fingers. "A year ago! Someone called and said they'd pay me to know what quirks could be combined to make a co-ordination based warp!"
The whole class turns to stare.
"What?" He tilts his head. "You guys don't get calls like that?"
"NO!" They all yell.
"huh..Well it was a very fun conversation anyway."
"Oh my gosh, Izuku." Bakugou sighs, facepalming.
The last villain finally steps out. "Well, looks like All Mighht didn't show. Are you sure the schedule was right?"
"Oh my gosh!!" Izuku runs forward. "You're the one who broke the gate."
"What?"
"Your quirk, it's disintegration or decay, right? Maybe dehydration?"
"How-"
"Quirks reflect in bodies, even if they're only mental types. Like how Shinsou's hair rises a bit! And your skin is a clear reflection of your quirk, unless you have bad skincare, but even people going without skincare for years don't get like this. It's mostly just spots. So your quirk is showing on your skin in flakyness! Which means you have something that can cause flakes or damage! Like decay!"
"Midoriya, right?" The villain chuckles.
"That's me!"
"Sensei said to thank you for all your help with the nomus, and Kurogiri here."
"It's no problem!" He grins. "uh..who's Sensei and Kurogiri and the Nomu's?"
"Kurogiri here is the warp." Handy gestures to the purple mist, who waves. "And a nomu is...well, that." He points at a giant muscular bird with its brain exposed.
"Woah.." Izuku steps toward it, poking the flesh. "Did you use the blood method or another way? I think you'd have had to use both for something like this! And the brain has been altered to! It's completely missing the prefrontal cortex!"
"My sensei can take and give quirks. So, both probably. You'd have to ask the doctor."
"Your doctor has an amazing hand! This level of precision in brain surgeries and experimentation is really rare." He climbs up the Nomu's back, checking every detail he can. "Let me guess. Uhm.. Enhanced speed, because the legs. Enhanced strength, because of the arms. Uh, shock absoption because of the brain being exposed!"
"Good go. But there's one more."
"Really?!" Izuku gasps, grinning widely. "Oh, this is so exciting! Who's it meant to fight?"
"All Might."
"Then regeneration!"
"Huh. Sensei was right. You are smart."
Izuku giggles. "I would hope so!" He climbs back down. "Midoriya Izuku!"
"Shigaraki Tomura." The villain shakes his hand, pinkie lifted.
"5-point activation? I knew it!"
"Yep. Now, while I kill some kids, you wanna meet my Sensei for real?"
"Kill?" He tilts his head. "1-A?"
"Yeah. All Might will show if they're dying."
"My princesses, princes, and royals?" Izuku blinks innocently, smile feeling more forced.
"Your what?"
He giggles. "Wow. You really don't know me after all."
"What are you talking about?"
"You see, Shigaraki, I'm the royal advisor. Whoever I teach, advise, will be a hero. They all came to the hero course for that reason. And now I've dubbed them my own, my royals. And an advisor would never let a villain kill them." He chuckles, hands behind his back.
"You can't touch me."
"Oh, on the contrary. Advisors are often overlooked as they do things behind the scenes. But, did you know, one of the behind the scenes things is especially important. Do you know what it is?"
"What?"
"Assassination." A knife flies into the villains chest, lodging in his heart as he coughs up blood.
"f-fuck."
"I've taken out many who've opposed me and my royals. I provided you a subject for an experiment too. You want to know why? Cause he was gathering a group to hurt my Prince Bakugou, to persuade me to make him a hero instead."
Shigaraki falls to his knees, red liquid spreading across the ground.
"The reason no one messes with me, or my royals, is because no one is alive to."
Life drains from the villains eyes.
"Now." Izuku claps his hands together, turning to the class. "Let's round up these thugs and get back to class, shall we?"
The all nod, gulping.
