FUBAR

Summary:

A soldier from a lost Battalion, now out of time and in a brand new place is now tasked to train the newest generation of UA students. He has proven himself with his men, his brothers and sisters in arms; but can he handle Japan's future Heroes?

Can the students handle him?

He has been tasked to get them ready for their first day as Pro Heroes, and he has been given free reign to do so as he sees fit. Preparing the classes for urban fighting and laying the basics for SERE training, he has a few weeks before their USJ trip, and a month and a half before the Sports Festival. Can he get them ready in time?

Notes:

This has been in the works for a long time, happy to finally get it out.

I've been wanting to write a My Hero fic for a while now.

Chapter 1: First Class

Chapter Text

“What do you think Heroics is going to be like now that All Might’s gone?” Someone said from behind him. Izuku couldn’t tell who said it, too focused on the idea of having a new teacher following All Might’s rather disastrous class.

 

“I wonder who we’ll get, kero.” Tsuyu asked. Aizawa wasn’t much help, simply telling them that their new teacher would be there soon and disappearing under the desk with his sleeping bag.

 

It was during their musing that they heard it, something was stomping loudly down the hall towards them. “W-what’s that?”

 

Slowly the stomping grew louder, and closer. Even Bakugo sat in silence as the class waited with baited breath. “Is-is it a Villain?”

 

“Nonsense, no Villain could get this far inside UA.”

 

“Well something’s coming.”

 

“And I think we’re about to find out.” Sure enough, the stomping had stopped outside their classroom, and 1-A didn’t have to wait long to discover just what had been making the racket outside.

 

The door flew open, bouncing hard off the wall behind it revealing an absolutely massive armoured figure as it stomped confidently to the front of the room. Cutting quite the imposing figure with the sheer amount of armoured bulk adorning them, not to mention the plethora of scars, craters, and duct tape covering their suit. It looked like the suit was a minute away from falling to pieces, what with its hodgepodge construction of armour plates, tape, and barbed wire; yet Izuku just knew that even he would struggle with it, and the class as a whole could not help but feel utterly intimidated by it all.

 

Or maybe it was the giant machine gun that was just thumped onto the desk.



“Why the hell are you not at the Beta Grounds!” It-no, He boomed, his voice echoing around the room. 

 

“W-we were told to wait here.”

 

“And who told you that?” The giant asked.

 

“Ai-Aizawa-Sensei did, he said you were coming here.”

 

“And where is this shen-shay of yours?”

 

“U-under the desk.” Tsuyu stuttered out, pointing to the desk he was standing beside.

 

Glancing back, he could just barely see a sliver of a yellow sleeping bag under it. Grunting, his hand dropped to his side, slowly rising up again with a slightly smaller, massive gun with it. Poking the end under the table, he pulled the trigger.

 

Bang! Bang! Bang!

 

The entire desk jumped almost a foot into the air as it flipped, Aizawa scrambling out of his sleeping bag as he tried to stand, run, and fight at the same time, all while still trapped in his cocoon. Suffice to say, all he did was embarrass himself as he collapsed in a pile of limbs and cloth.

 

“Get up. Your sorry ass was supposed to be at Beta ground with your class fifteen minutes ago now.” The bulky man ordered their teacher.

 

“What was that!?” Aizawa yelled up at him. “What were you thinking shooting that in here? Why do you even have those in here?”

 

“Because I actually work for a living. ‘Sides, you chose to put your sleeping over your students' careers. Be glad I don’t just fail all of 1-A for that.

 

“Now.” The man said, grabbing his machine gun from where it fell. “Are you going to get up, or do we need some more encouragement? I promise these ones won’t be blanks.”

 


 

“Now, your last teacher here was, frankly, an idiot.” The man said as they all walked over to the training ground.

 

Immediately class 1-A broke out into muttering, apparently getting over their fear at the slight at All Might. 

 

“Hey!” One particularly brave, or idiotic, Iida called. “All Might was a perfectly serviceable teacher.”

 

“And he pits you children against each other without any training, what would have happened if one of you killed someone? Hell, one of you almost did.”

 

Letting his echo die down he continued. “And that’s where I come in.”

 

“Y-y-you, you’re…” Izuku stuttered.

 

“Spit it out already.”

 

“Y-you’re teh, the Damned Hero, Iron Man. I-I saw your debut.”

 

“Then you’ll know how I run things. Now, someone, for some fucking reason, has decided to put me in as the replacement, and I am here to make sure you brats will survive your first day. Get changed and meet the rest of us outside.

 

“You got five minutes!” He called.

 


 

Classes 1-A and B met up again inside Beta Grounds across the campus, wearing a mix of their Hero costumes and UA’s gym uniforms. Both were surprised to see the other class as they stood in a plaza surrounded by short, squat buildings as they waited for their teacher to return.

 

“What do you think he’ll teach us?”

 

“Is this just going to be another building fight?”

 

“Like with All Might?”

 

“Yeah, that class was fun.”

 

“You were taught by All Might!?”

 

“Bull-”



“Then it’s a good thing we won’t be doing that then.” Iron Man called as he kicked open one of the doors, blasting it off its hinges as he stomped out to stand in front of them. “As you may have heard, I am the Hero Iron Man. You may call me Sir, or Captain. Now, I don’t care what your schedules say, or what you think you should be learning here, this is my class now; and I will teach it how I will.

 

“Your classlist may call this class ‘Heroics’, but I will not be teaching you how to be a Hero. I will be teaching you Urban Warfare and survival, you will listen to my instructions or you Will be removed from this class. I do not care about your opinions or what you think a true Hero is, this class will teach you to survive your first day out.



“So listen up! There are two rules here: Rule one. You’re no use to anyone dead. Rule two. …

 

“Ah forget it, half of you will wind up dead anyway.”

 

“What!” Mina yelped.

 

“What do you mean by that?” 



“I’ve seen your files, most of you either focus heavily on just those quirks of yours; or you just blew off training thinking you could just skip your merry fucking way through this course. Well news flash;

 

“You Can’t!

 

“You rely on your… ‘Super Powerful’ quirk, you Will die. You try and coast in my class, you will be Expelled. I don’t care if you’re here by recommendation from fucking God himself, or one of the Comission’s little pet projects; if you fuck around here you will be removed. I do not give chances…” He trailed off as he spotted a pair of floating gloves.

 

“And You better fucking be wearing something!”

 

“I-I ahh… I-I’m.” Tooru stuttered out.

 

“Put some fucking clothes on.” He ordered her. “The rest of you, we’ll be going over some scenarios to test your ability to think on your feet.

 

“You Spiky-hair.” He shouted, pointing at Bakugou. “Hostages on the fifth floor, building’s rigged to blow. How are you going to get them out?”

 

Knocking his fists together, he shouted his answer. “I’m gonna make them regret messing with the new Number One. I’m gonna beat them so hard-”

 

“Failed! You just blew up the entire block.

 

“Next. You, Big-hair.” Pointing at Kinoko. “You’re surrounded by armed goons, how are you getting out?”

 

“I-I, uhh…” She stuttered, clearly panicking.

 

“You’re already dead, think faster.

 

“Next. Bubblegum. Five story building, barricaded suspects. What are you doing?”

 

Panicking, Mina hesitated for a second before she answered. “I-I run in and use my acids to-”

“Failed.” He interrupted her. “Killed or captured. Wait for reinforcements, or become bulletproof; never go in alone.

 

“Purple-balls. Vehicle kidnapping, other end of the block. How are you catching them?”

 

“I use my balls to build up speed and launch myself at the car.” Mineata said very confidently.

 

“Too slow, they already disappeared in the grid.

 

“Short green. Gunman with a hostage.”

 

“I-I-I”

 

“Get on with it.”

 

“I-I can launch myself at him and punch him?” Izuku finally answered.

 

“Are you asking me or telling me?”

 

“Telling. Sir.”

 

“Good. Gunman is neutralised and your hostage is traumatised, but they're alive. You pass.”

 

“What!? How the hell did Deku pass but I didn’t?” Bakugou exploded.

 

“Because he wouldn’t have blown up an entire block or gotten himself killed, and he wouldn’t have killed the hostage. Now shut up and listen, Back-hoe, because we’re moving on.” Iron-Man stated.

 


 

“-And coming up next Is a Hero who took the scene by surprise, coming with personal recommendations from the top and refusing to give his name. Let me introduce you to:

 

“The Damned Hero: Iron Man!”

 

Stomping out onto the stage in all his ragged kevlar plate-mail glory, gildings made of pure gold gleamed in the sunlight as they stood out on the deep red silk scraps holding his pads together. He was rather intimidating standing at over two hundred centimetres and weighing almost two hundred kilos, every step seemed to shake the entire crowd as the stage creaked under him.

 

Stepping up to the edge and resting his large gun on his shoulder as he spoke, his rough-shaped steel visor glinting in the light.

 

“The Armour’s here!” He boomed, voice carrying through the room even without the microphone. “Stay behind me, and you’ll make it through.”

Chapter 2: S.S.D.D

Notes:

Well, it's been a while since I updated a story this quickly, enjoy.

Also worth noting, the smaller linebreaks are for small timeskips instead of a full scene change. And yes, he is going to be using nicknames he comes up with for a lot of the students.

(See the end of the chapter for more notes.)

Chapter Text

“Alright class, today we will be talking about rescue scenarios.” Iron Man announced to the two classes as they stood at Beta Grounds again. “For these next few classes we will discuss the basics of firefighting, first aid, how to move a victim, when Not to move a victim, and we will talk about some field surgery procedures you may need to perform. It is my hope that all of you will leave this school with the skills and knowledge to survive your first year.”

 

“Why do we need to know this useless crap?” Bakugou shouted. “We don’t need this to fight Villains.”

 

“And what are you going to do if there aren’t any?” Iron Man rebutted. “Are you just gonna watch some kid die in a pool of his own blood while you just stand there? All because you didn’t need to know basic first aid.

 

“Well, would you?” Bakugou remained quiet, seething at him. “Didn’t think so. If you don’t have anything actually important to say, then stay quiet.”

 

“Um, Sensei. Are we actually allowed to give medical attention?” Some girl he didn’t have a good name for asked.

 

“If you get in trouble for giving ‘unlicensed’ first aid, then that means you and them survived long enough for some dumb fuckers to bitch and moan. Any life-saving measures taken by you are protected by the same laws that let pro -heroes run around punching people’s heads in.

 

“Any other questions?” Seeing that nobody was going to speak up, he continued. “Good, moving on.



“This, is a fire extinguisher.” He said, setting one on a table in front of him. “This is an ABC extinguisher, it can be used against most common fires you will encounter; these can be found almost everywhere, as all public, government, and company buildings and vehicles should have at least one.

 

“They can also be used as improvised weapons, making an effective club; they can even be used as grenades, when shot or superheated they can explode producing a disorienting concussion effect and shrapnel. Both of these attacks can kill, so be careful.”

 

“Are- are you supposed to be teaching us to do this.” Bubblegum asked him.

 

“Why would I not teach you what can and can’t be used to defend yourself and others? Now, if there’s nothing else?

 

“Alright, there are forty of you, but Nedzu only let me get ten of these. So buddy up, groups of four, and grab one; we’ll be going over how to use one, and how to properly fight a small fire.

 

“Understood? Good, get started.”

 


 

“Angh, unf.” Twisting and writhing in his bed, the Captain grunted as he tossed in his sleep. His moans and groans could be heard throughout his apartment, interjected with strangled yells echoing down the hallway. 

 

His two “roommates” stirred from their sleep at one particularly loud yelp, rolling over the one tried pinning her ears under her pillow as-

 

“Raagh!”

 

She sprang up, instantly awake, grabbing one of his hammers as she ran out of her room, searching for an attacker; finding nobody and nothing out of place, she went to go check on him. Creeping up to his door, she slowly opened it to-

 

Click.

 

Click. Click.

 

Stare down the barrel of his massive so-called pistol, as he was repeatedly pulling the trigger as if to summon bullets into existence through sheer force of will. Slowly, she put her hand on the gun, gently taking it from his hand. Slowly placing a hand on his shoulder she guided him back over to the bed, sitting him down as he stared at her with his blank, wild eyes.

 

It honestly hurt her a bit to see that look.

 

She sat beside him on the bed, she knew by now how to handle his night terrors. They didn’t say anything, she just sat with him as he relived his memories.

 


 

“Today we will go over basic medical techniques. You will learn how to tie a tourniquet, how to pack a wound, set a splint, what to do with an impalement, and how to move a victim. 

 

“Are there any questions before we begin?”

 

“How are we going to be learning these?” Mushroom girl from 1-B asked.

 

“I have convinced Nedzu to acquire four medical training dummies, these manikin look-alikes are designed to mimic several injuries, and are capable of bleeding to properly simulate them.

 

“Hope none of you are afraid of blood, heh.”

 

“We’re using actual blood!?” Vine girl burst out.

 

“Alright, since there’s no more questions, let’s get to work. We’ll start with one of the most important things you can learn from this class, the tourniquet.

 

“With one of these, it could mean the difference between life and death. Apply one of these Properly, and you’ll be fine; do it wrong, and you’ll be dead in minutes.”

 

————

 

“Alright, alright. That’s good enough, we’ve got to move on.” He called as the students stopped what they were doing. “We don’t have that long to go over all you need to know, so let’s pick up the pace.

 

“Next on the docket, packing wounds; the second of the most important things you will learn here. I have also given both your teachers a list of basic supplies for Individual First Aid Kits, I strongly recommend you all to carry one whenever you go out, especially for Hero work. And remember, this is Your first aid kit, for Your injuries.” Once he was sure his point got through to them, he carried on to the next point of their class. 

 

“Now, how to pack a wound?

 

“It’s quite simple really, just stuff it with as much gauze as you can fit in it.”

 

“Is, is that really it? Just stuff it in?” Horns asked.

 

“Pretty much, your job isn’t to fix them, it’s just to make sure they last long enough to see someone that can. But you must remember this:

 

“You Can Not pack a chest wound, you Can Not.

 

“You can only pack wounds on the arms, legs, and joints.”

 

“Why not?” Someone asked, he couldn’t tell who.

 

“Because your chest is hollow, and full of squishy organs that’ll love to go pop when you press on them. Answer your question?” Seeing that quite a few of his students now looked rather green, he continued. “The training dummies in front of you have several slashes and holes in their arms and legs, pick one to work on.

 

“You each have several yards of old plain gauze, you will pack it into your wound until you stop the bleeding for several minutes. In real usage it would be preferable to use sterile hemostatic gauze, or just clean gauze period, but in a pinch anything absorbent will work; I’ve packed wounds using T-shirts before.

 

“But tampons will Not work, they do Not absorb enough to stop the bleeding; and they can Not apply pressure. They might work on tiny injuries if you have absolutely nothing else, but do not expect to just be able to shove one in a hole and expect it to save their life.”

 

Once they had all gathered around the dummies, he carried on with his instruction. “Everyone ready? Alright, let’s get started.

 

“You can either place your gauze on the patient, on the ground, in your pocket, or just toss it over your shoulder, you’ll need both hands for this; don’t worry about getting the gauze dirty, they’re already getting an infection, just focus on keeping them alive.

 

“Take the end of the gauze, or as close to it as you can get, and stuff it into the wound, press it in with your fingers. Next, with your other hand, layer the gauze over you first then press it in, slipping your fingers out from under it as you press; make sure you keep good pressure on it at all times, use your fingers, do not use your palm to apply pressure, it will not apply enough. Now, keep layering it and stuffing more into the wound.”

 

————

 

“Alright, that’s all we have time for today.” He announced. “Go get changed and clean yourselves up. I’ll deal with this.”

 

Looking like they just came from a warzone the two classes walked back to their homerooms looking sick, their hands and arms painted red; some of them walking in an almost trance-like stagger with a far away look. Hearing the heavy footfalls of his hidden observer landing behind him, he paused in his clean up as she walked over.

 

“Did you really need to do that?”

 

“They need to know these things.” Was his simple response.

 

“Did you not see the looks on their faces?” She asked him.

 

“I did. And they would’ve been a hundred times worse if they needed these skills and didn’t have them.

 

“Enough of that. How’s Vampire?”

 

“The kid? She’s still a little shaken up from last night, but she’s coming along well enough.”

 

Sighing, he actually set his garbage bag down to face her. “I guess that’s the best I can hope for, I’m still worried for her; after all the shit that she’s been through, I just… I just don’t want to lose her too. I just don’t want to fail another kid.”

 

“I know, I know. And she’s come a long way since you first brought her back.”

 

Sighing again, he spoke. “Yeah. I’m proud of her.

 

“It’s been nice talking with you again Playboy, I’ll see you back at the house. You bringing Dragon?”

 

“Yeah, she’ll be there. I’m bringing dinner this time.” With that she jumped off, leaving him to go back to his cleaning.

Notes:

It should go without saying: do not use this fic as real medical knowledge, the procedures described are really simplified emergency field operations. Get proper training.

Except for the tampon and chest wound parts, those are real facts.

Chapter 3: Into the Pit

Notes:

Finally, some actual quirk use; and a little time-skip, cause would you really want me to describe every single class.

Edit: screwed up the scoreboard, fixed. Sorry Manga, didn't make the cut.

Chapter Text

“Alright, welcome back class, today we will be doing something a little different. Almost all of you did well in your introduction to field aid,” He looked pointedly at Bakugou as he said that, “But I feel it’s time for a change of pace; you all have been through almost a full week of the Hero course, and I want to see where you all stand. 

 

“Which is why I’ll be running you all through the Pit.” He declared, gesturing to the buildings beside him. Brightly coloured signs warning of “live fire zones”, eye protection requirements, and no glass being allowed beyond them littered their walls.

 

“Sensei, what is the ‘Pit’?” The rich girl, whose tongue-twister of a name he couldn’t remember, asked, wearily eyeing the buildings; though it wasn’t her question he focused on.

 

“Why are you dressed like a stripper?”

 

“I-wha- my quirk requires exposed skin.”

 

“And you chose to wear two ribbons and heels?” He asked, incredulous. “Are you trying to get yourself killed? Wearing heels, into a fight? And why do you have a shelf, on your ass?”

 

“This is the uniform I was provided from Deternet, and it was designed to make the most effective use of my quirk. And the Yaoyorictionary is a vital part of using my quirk.” She defended herself.

 

“And you have ab-so-lutely Zero protection from any- wait. You actually call it that?”

 

“Yes, it is vital in using my quirk to its fullest, and it’s held closed by magnets so it can’t fall off.”

 

“And how is that supposed to help you when it breaks your back because you landed on it?” He shot at her. “And that still doesn’t help you with having no fabric on you. Right now, you are one of the biggest liabilities here, because you have exactly Zero protection; a child with a pellet gun could take you out.”

 

“What? What do you me-”

 

Pulling out his pistol, he fired a shot towards the Pit, catching the casing. “Allow me to demonstrate.” With that, he flicked the hot shell at her; landing it right between the strips of fabric she called a uniform. And while she was panicking about the hot piece of brass landing somewhere rather sensitive, Iron Man casually walked up to her, and simply shoved her over with one hand.

 

While Momo lay on her back, folded over her back shelf, groaning, Iron Man turned to address one of his other problem students. “And you! I thought I told you to put some clothes on.”

 

“Y-you told us to wear our hero uniforms, t-this is my uniform.” The floating pair of gloves defended, waving around wildly.

 

“This? Your uniform is Nothing!?”  

 

“Y-yes. This is w-what I was given.”

 

Sighing, he turned back to the rest of the class. “Get Printer off the ground and put some fucking clothes on. And both of you are staying after class, we need to discuss just what is considered appropriate wear for field work.

 

“And the rest of you, will be running the Pit. This course will test your speed, accuracy, and reaction speed.

 

“If you direct your attention to the board beside the entrance, you will see several times listed on it, set by myself and some volunteers.”

 

“Woah, no way. You got Miruko to do this?” Bubblegum exclaimed.

 

“Yes, Miruko was one of the volunteers. Now, here’s what’s going to happen:

 

“When I call your name, you will step up to the red line here.” He called, gesturing towards the door marked “in”. “You will then find yourself in an open hallway, run through this hitting every target until you get into the next room; there you will be met with the first of the hostages, do not hit them, take out all targets then move up the stairs; there you will face another target run, this time with hostages; up the stairs again, then drop out the window; wide open space, high targets, lotta civies; get through, into the final gauntlet room; then finally sprint to the end there.” He finished, pointing at a yellow circle outside the second building.

 

“Don’t be afraid to use your quirks on the targets, I have a few hundred of these damn things. If you do it fast, and accurately, enough your name will be added to the board; if you beat my score… I’ll buy you an ice-cream or something.”

 

As one the class turned to look at the scoreboard, and the six times currently listed on it:

 

  1. Iron Man 8:20 60/60
  2. All Might 8:50 59/60
  3. Miruko 8:09 53/60 -2
  4. Ryukyu 9:37 48/60 -1
  5. Midnight 10:01 47/60
  6. Vampire 14:45 49/60 -1

 

“As you can see, time is not everything; you can blitz through the course in nineteen seconds and still come last, if you don’t hit all your targets, or you hit all the hostages, you will still fail. The rules are simple. Go fast, hit accurately. You can use your quirks as you see fit, but any destruction of the course will result in a failure.



“Got it? Let’s begin.”

 

————

 

“Horns. 10:37, 43/60. No civies. Next!

 

“Mushroom. 12:21, 31/60. Two civies, get better. Next!

 

“Bubblegum. 9:50, 51/60. One civie, did good. Next!

 

“Gravity Girl. 10:24, 47/60. Good. Next!

 

“Engine Legs. 7:18, 17/60. Four civies. Failed, I said you have to actually hit the targets. Next!

 

“Comic Head. 13:20, 48/60. No civies. Next!

 

“Short Green. 10:35, 44/60. No civies. Next!

 

“Tetsutetsu Tetsu… tetsu? Wow… that’s a… that’s certainly a name, your parents must’ve hated you. 12:28, 49/60. One civie. Next!

 

“Back-hoe. 10:15, 47/60. All civies killed. Failed! You destroyed the track, you fail, and now we can’t run the rest of the class.”

 


 

The final scoreboard was set up outside the entrance of the ruined course:

 

  1. Iron Man 8:20 60/60
  2. All Might 8:50 59/60
  3. Miruko 8:09 53/60 -2
  4. Midnight 10:01 47/60 
  5. Ryukyu 9:37 48/60 -1
  6. Ashido 9:50 51/60 -1
  7. Uraraka 10:24 47/60
  8. Izuku 10:35 44/60
  9. Pony 10:37 43/60
  10. Tetsutetsu 12:28 49/60 -1

 


 

“Impossible! How did Deku beat Me!?” Bakugou whined.

 

“I-I’m sorry Kacch-”

 

“He passed because he listened to my instructions to Not destroy the track, and to Not hit the hostages. You not only blasted your own way through my track, making it so no one else can run it, but you also hit every single civilian in it. Even if I put your score on the board, it would be so far down that I would need to count to Fifty, at least, just to list yours.

 

“Oh yeah, you also have two weeks of detention, with me.”

 

“What did you say to me!?” He demanded.

 

“Three weeks now, hope you’re ready to run.

 

“The rest of you, we’re having a field trip after next class, dismissed. You two, with me,” He said, pointing at Momo, and Tooru. “King, watch the destructive brat.” He called to 1-B’s teacher.

Chapter 4: Touch the Sky

Notes:

(See the end of the chapter for notes.)

Chapter Text

The two classes met together yet again in Beta Grounds standing outside the Pit, which was still showing signs of Bakugou’s rampage yesterday; though it was clear they had already started fixing it for the rest of them to run it.

 

“Welcome to day two of the Urban Maneuvering Courses. Today we will be covering the basics of rooftop movement and fighting. At some point in your careers you will have a fight or chase on a rooftop, and you must know how to deal with it or you will die.”

 

“How are we going to train for that, Sensei?” Bubblegum asked, clearly already dreading the answer.

 

“Why, by doing it. What else did you expect?” She gulped, but accepted the answer. “Now, unless we have any more questions? No? Then follow me.

 

“Hope none a’you are scared of heights, heheh.”

 

————

 

Izuku stood at the edge of the building that Iron Man-sensei led them through, standing in one of the open windows as he looked out over the fake cityscape beyond. Only a simple nylon net stopped him from taking the “quick way down” as Sensei put it. He was trying to settle himself for the test even as their demonstrator ran the Gauntlet, a rooftop obstacle course; not even being in a class being led by Miruko herself was enough to distract him from what he’s about to do.

 

Ten stories.

 

That was how far up they were.

 

A hundred feet.

 

Over thirty-two metres.

 

That was what lay below them. They were going to be running the lowest of Sensei’s rooftop courses, leaping between building and jumping alleys; with nothing but nets to catch them if they missed.

 

But Izuku would still make himself compete, he didn’t have a choice if he wanted to be a hero. Sensei’s right, they needed to know how to do these things.

 

Three seconds.

 

That was how long they had to think, if the nets didn’t catch them. Three seconds before they hit the ground.



That was a long time to think for.

 


 

Ochaco could hardly believe what she was doing, leaping through the air as she used her powers on herself to clear the gap with ease; nausea creeping in on her as she managed to land in a run. What she was doing was insane, no normal person would do what she is, right?

 

And yet on she pushed. Only driving herself harder as she sunk everything she had into running the course, even as her nausea spiked and she couldn’t hold it down any longer. She did her best to fight through it, pulling herself back to her feet even as she spat the last bit of rainbow from her mouth.

 

Staggering her way into a run she carried on, ducking under a pipe she lunged into another leap; floating through the air as she cleared the alley far below.

Iida grunted in pain as he pushed off the roof he had crumpled onto, his engines revving up again as he tried to get every ounce of speed he could get from the short distance he had. Reaching the edge, he kicked off; flying through the air at high speed.

 

Clearing well beyond the gap with ease he came down hard, his foot touching the gravel roof and digging into it, deep.

 

Yelping as his feet disappeared out from underneath him, he slammed face-first into the roof; sliding across it with a massive fantail of gravel he hit an air-duct, flipping over it he flew through the air, clearing half the roof, until he smashed into an air-conditioner.

 

Slowly peeling off it, leaving a near perfect Iida-shaped dent, he collapsed to the roof, breathing hard as he fought to move. Whether to get up and keep running or what, not even Iida knew.

 

[Alright, Engines, I’m calling it. That’s enough, you did good but you got a lot to work on. I’ll send someone to get you back down here.] Iron Man announced over his PA system.

 

Iida groaned as he fell back to the gravel.

 

————

 

“Watch how it’s done 1-A. Watch and learn.” Monoma taunts, whether he thought they could hear him or not was anyone’s guess. His attitude made it clear what he thought of his abilities, so it should’ve been clear just how he would’ve performed when he got to the first gap;



And completely missed the jump, running face-first over the edge as he fell to the net below, screaming even well after he landed.

 

[Get out of the- Stop screaming. Get out of the net and get back down here, we need to have a little talk about some things.]

 

————

 

It should be to no one's surprise that Tsuyu did remarkably well on the course.

 

————

 

Kiniko did surprisingly well on the course, managing to make it through most of it before she missed a jump.

 

————

 

Mina managed the first few gap jumps, but then she started getting cocky and decided to show off. Using her skills and flexibility to weave through his obstacles with a seemingly inhuman ease, though her hubris was her downfall; she couldn’t quite make the shift from her Kong turned front-flip over some ducting, and missed the roof entirely.

 

[Don’t get cocky, fast don’t mean shit if you can’t hit your marks.]

 

————

 

Mineta did better than anyone really expected him to, making it through most of the course until he overestimated a jump, and slammed face-first into a pipe.

 

————

 

Momo did remarkably, even with the unbalanced temporary uniform she wore; an old plate carrier modified to be backless worn over a cut-up t-shirt, letting her use her quirk near unrestricted while also giving her some protection. 

 

She was one of the few students who actually managed to complete the course.

 

————

 

It was Izuku’s turn now, and he was still quite nervous about it, but he was still going out there. After all, isn’t being a hero doing what’s needed, no matter what? 

 

And surely UA wouldn’t make them do something that could actually hurt them. Right?



He still managed to break several of his bones, with Iron Man ultimately calling it over despite Izuku’s attempts to continue with two broken arms and several cracked ribs.

 

————

 

“Alright, that concludes today’s class. Remember that we will be having the field trip tomorrow, all of you are to gather at the main gates after lunch, you have all been excused from your afternoon classes.

 

“And for all of you, the Pit will be open every Saturday from ten to fourteen hundred; the Gauntlets will be Sundays, same time. I recommend you make use of that. Dismissed.”

 

————

 

As soon as the class got out of sight from the test buildings, Bakugou shoved Izuku into an alley. “You think that just because you fooled the teachers into thinking you have a quirk that you’re better than me?” Kacchan demanded as he pinned him against a dumpster. “All the shit you pulled before just wasn’t enough for you, was it? You just had to sneak your way into UA too, ruin my story, my chance at getting to show the world what the next Number 1 looks like.”

 

Slamming his fist into Izuku’s gut, he let off an explosion as he sneered at him. “You were always looking down on me.” Another punch, another explosion. “You always tried to ruin my achievements.” His third punch knocked Izuku to the ground, the dumpster he was pinned to clattering down the alley.

 

Bakugou didn’t care about the noise he was making though, or about the thunderous clattering that was approaching him, he was firmly focused on Izuku. Slowly stalking towards his fallen form as small explosions crackled up his arms. “You just refuse to learn your place Deku. You keep trying to be something you can’t be: worth something. Well you’re gonna learn it today, and this time the lesson’s gonna stick.” He said, popping one of his pins.

 

“You should have just ju-”

 

“What The Hell Is Going On Here!?” Iron Man shouted at them as he grabbed Bakugou’s shoulder, spinning him around mid-punch. A punch which missed Izuku on account of no longer facing the same direction as him, but his punch didn’t miss everything; no he hit something, even though he later wished he didn’t.

 

He hit Iron Man, square in the plating on his chest.

 

And exploded.

 

With the full tank of his sweat.



The blast left Bakugou staggering back coughing heavily as his bracer fell off his arm in pieces, a large cloud of smoke and dust filled the alleyway in front of him as the walls, and even the ground, were pulverized from his quirk. It was as he was staggering towards the more intact of the two walls, still trying to catch his breath, that he got his second big surprise of the last thirty seconds; a large gloved hand erupted from the smoke to grab him by the neck, pulling him off his feet as a bulky figure slowly stomped out of the cloud.

 

Dangling from the hand around his throat as his feet beat pitifully on the asphalt beneath, he was helpless to do anything but watch as a scuffed and thoroughly Pissed Iron Man stomped into view; looking no worse for wear, aside from some new scuff marks, and the plate Bakugou hit having cracked. The hand that wasn’t holding him up was raising that massive chrome pistol of his to press against Bakugou’s head.

 

“I’ve seen enough.” He snarled.

 

Bakugou could only whimper around his hand, unable and unwilling to try anything else, before he was tossed aside. Sparing a glance at Izuku’s crumpled form on the ground to check for major injuries, he turned to follow the thrown would-be murderer.

 

Spying Bakugou trying to get back up, he seemingly materialized his giant machine gun and fired a shot beside the student; the resulting explosion made him freeze in place, and silenced the area so much that you could hear the familiar green shell casing ping off the wall.


“King! Get him to medical!” He shouted, jabbing Bakugou in the head with the muzzle of his giant shotgun. “I’m taking this thing to go find his lazy piece of shit teacher, then I’m taking them to the Rat for his expulsion and arrest. Get up.” Growling the last part to Bakugou as he jabbed him again the two set off, marching past the two classes as they stood there shocked.

Notes:

I'm toying with a group chat chapter to fill the gap between this chapter and the field trip, and to show the class perspective on Iron Man and his classes. I'm not sure how well it'll come out, or if it'll just get scrapped yet. Enjoy little omake of Iron Man's introduction to Tsuyu:

IM: So what can you do?

Tsu: I'ma Frog.

IM: ...

Tsu: ...

IM: So you are. Carry on.

Chapter Text

Froppy:

So what did you guys think of todays class? Ribbit.

 

Twogenium:

I tink the ponies wer toooo mush

 

Uravity:

 

What?

 

Rock’n’Roll:

 

I think he’s still a little out of it from that crash.

 

AcidQueen:

 

Enough about that. Jirou. you heard what was going on with him.

 

AcidQueen:

 

Spill.

 

Rock’n’Roll:

 

He was screaming something about Midoriya “ruining his life” and “teaching him a lesson about remembering his place”. From the aftermath of it, I think the place he meant was six feet under.

 

Momo:

 

I can’t believe I complimented him.

 

Casper:

 

We all literally didn’t know better.

 

Casper:

 

Though he did almost kill the three of you in all mights class.

 

AcidQueen:

 

Oh yeah. i almost forgot about that.

 

AcidQueen:

 

Why didn’t Sensei expel him for that?

 

Froppy:

 

Guess he had more than zero potential?

 

Uravity:

 

Then why would Aizawa-sensei say he would expel us for not passing his test?

 

Rock’n’Roll:

 

And for not getting changed fast enough.

 

Pichu:

 

Don’t forget asking questions.

 

Rock’n’Roll:

 

Right, I almost forgot about that.

 

Rock’n’Roll:

 

Wait. Kaminari?

 

Pichu:

 

Yes?

 

Casper:

 

I kinda forgot the boys were in this chat, why haven’t any of you said anything?

 

Pichu:

 

We’ve been a little busy.

 

Momo:

 

Doing what?

 

Pichu:

 

Things.

 

Uravity:

 

What kind of things?

 

Uravity:

 

Kaminari?

 

AcidQueen:

 

And he’s gone.

 

Froppy:

 

F

 

Momo:

 

What’s that?

 

Froppy:

 

You wouldn’t understand. Ribbit.

 

Momo:

 

Why not?

 

Froppy:

 

Ok, back on topic. Today’s class, what think?

 

Momo: 

 

Why wouldn’t I understand Tsu?

 

AcidQueen:

 

I thought it was fun.

 

Rock’n’Roll:

 

Until you fell off the roof I bet.

 

AcidQueen: 

 

Still fun.

 

Uravity:

 

I can’t deny that, it was a rush flying over those gaps. I kind of want to do it again.

 

Rock’n’Roll:

 

I didn’t take you for an adrenaline junkie.

 

Uravity:

 

So I like the rush. Sue me.

 

Uravity:

 

Please don’t actually.

 

Momo:

 

I must agree, these classes have been rather fun.

 

AcidQueen:

 

See, even Yaoyourozo agrees with me.

 

AcidQueen:

 

Oh yeah. Kyoka. How are your ears?

 

Uravity:

 

Yeah, how are you?

 

Rock’n’Roll:

 

Still deaf, but the bleedings stopped. Recovery Girl says I should be able to hear again tomorrow.

 

Casper:

 

Well that’s good at least.

 

Momo:

 

Yes, I shall be wishing you a fast recovery.

 

Froppy:

 

Yay that you’re ok, but back to the topic you keep avoiding. Ribbit.

 

Froppy:

 

Today’s class marks the fifth we’ve had with Sensei, what do we think of him?

 

Uravity:

 

He’s intense. He kind of reminds me of some people I grew up around.

 

Momo:

 

I value his input, it is clear that he speaks from experience.

 

Momo:

 

Though I wish that some of his methods were different.

 

AcidQueen:

 

Still sore from yesterday?

 

Momo:

 

Yes.

 

AcidQueen:

 

Well you already know what I think of him. I like him.

 

AcidQueen:

 

Better teacher than Aizawa-sensei at least.

 

Uravity:

 

Not much of an achievement.

 

Casper:

 

What’s this, Uraraka sassing a teacher?

 

Rock’n’Roll:

 

I mean, is she wrong?

 

Froppy:

 

Not really.

 

Momo:

 

I apologise for saying that his ruse was obvious. Learning that he has actually expelled entire classes before, it has changed some things.

 

Uravity:

 

You’ve already apologised for that twice now Yaoyoruzu.

 

AcidQueen:

 

Yeah. Youre cool. We didn’t know Sensi would really do that.

 

Casper:

 

I like Iron Man-sensei, he feels like one of those people you can trust.

 

Rock’n’Roll:

 

I just wish he wasn’t so morbid.

 

Pichu:

 

And he clearly cares about us. Did you see how fast he ran off after that big explosion?

 

Rock’n’Roll:

 

No. I was too busy on the ground with my bleeding ears.

 

Uravity:

 

Kaminari? Where have you boys been?

 

Pichu:

 

Oop. sorry, gotta go.

 

Uravity:

 

Kaminari wait.

 

AcidQueen:

 

Too late.

 

Momo:

 

What are they doing?

 

Uravity:

 

That’s what I want to know.

 

Froppy:

 

Speaking of that explosion.

 

Froppy:

 

I noticed something off about him, before he ran off.

 

Momo:

 

What did you see Tsu?

 

AcidQueen:

 

Yeah. Come on Frogs, spill.

 

Froppy:

 

When the explosions went off he froze. It looked like he was scared.

 

He looked almost like a kid who got caught in the cookie jar instead of the Pro he is.




 

“Keep walking.” Iron Man growled at him as Bakugou was frog marched down the halls of U.A, the Pro’s muzzle still digging into his back as the two were stomping down the hallway as the other students stared in shock at them as they passed. Crowds parting like the sands around the snarling bastard being paraded at gun-point past them. 

 

Shoving through some purple kid he kicked the classroom door in, throwing Bak-hoe against the desk as he stormed up to Aizawa’s sleeping bag; grabbing the tail of it he pulled, ripping the man out from under his desk to thump against the wall. Hitting the ground, the man sprang to his feet with a roll.

 

“What The Hell!” Aizawa demanded, red jelly running down his face.

 

“Get the fuck up and work for once.” Iron Man ordered, dragging Aizawa and Baka-who out of the room by their collars.

 


 

“Vlad King already told me what happened.” Principal Nedzu said, even as Iron Man was still gently closing his door; Aizawa already slumped against the wall.

 

“Good.” Iron Man growled. “You’ve already started the proceedings then.”

 

“I’m afraid I can’t expel Bakugou.” Nedzu said placatingly.



“Explain yourself.”

 

“While I agree that Bakugou went far beyond what is acceptable in this school, and he will be punished as much as I am allowed, I am afraid that the board will not allow his expulsion; he has rapidly become their favourite, they’re already saying he’s a Number 1 contender.” The Principal explained, even as Iron Man grew visibly agitated. “I am sorry to say, they will never allow it as long as they think he’ll rank high.”



“You’re lucky I like you.” He eventually growled, then cleared his throat, before continuing in a normal voice. “Then he’ll be serving detention with me the rest of the year, and I will not teach that {fucker} anyth-”

 

At that Aizawa just had to interrupt. “You’re really going to punish a promising Hero for a small bit of harmless-”

 

Iron Man spun to face Aizawa, and for all the staring he does, he certainly didn’t see his fist coming. Cracking his head off the wall, Aizawa slowly slid to the floor, Blackhole sitting in wide-eyed silence.

 

“I’ll look past this one-time bout of roughhousing taken too far.” Nedzu said calmly. “Bakugou will be removed from your class, he will also be serving detention with you during his scheduled club and free time."
