Several days of school later, class 1-A arrived to see Aizawa-sensei standing at the front of the gates with a bus. He explained they would be going to a separate part of U.A, known as the Unforeseen Simulation Joint. It was a specialized area to help students with skills related to search and rescue. Everyone was excited for having a field trip so early on in the term, let alone in the year, and much to Iida's dismay, the class piled onto the bus in their usual disorderly fashion.
Eventually Izuku found himself sitting with Bakugo, and for some reason Asui (who sat nearby) turned the conversation to Bakugo's... less than amiable personality.
"Bakugo," Asui started, "what's wrong with your personality?"
"What the FUCK did you just say about me?!" Bakugo replied, meeting bluntness with bluntness.
"I mean, she has a point dude," Kirishima broke in, his hard-headedness showing in another of many ways. At least he had the defensive capabilities to deal with it.
"Yo, watch what the FUCK you're saying about me shitty hair! I have a FUCKING fantastic personality!" Bakugo retorted... somewhat proving his classmates' point.
"Man, you're just backing our point up," Kaminari jumped in as well. For some reason being idiotic without his quirk short-circuiting his brain.
"YOU WANNA DIE YOU ELECTRIC BAST-" Bakugo broke off with a start as the bus stopped, saving his classmates from hell. For now, anyway.
Everyone stepped out to look over the massive dome that was the USJ, before stepping through the doors to be greeted by Thirteen. "Greetings students of 1-A! I am Thirteen, and I will be teaching you search and rescue operations!" they began, Izuku managing to keep his motor mouth closed. Probably cause Aizawa-sensei was standing right next to him. "Today we will be focussing on..." they began to trail off, noticing Aizawa-sensei's hair standing on end. Everyone looked at the red eyed teacher, who began preparing to fight.
Their attention quickly turned to the target of their teacher's terrifying gaze, to see a purple mist with some... less than friendly looking people coming out of it. "Hey, fake villains, neat!" Kaminari said... still not having had used his quirk yet apparently. He was quickly met with a hard whack from Jiro, and Aizawa-sensei clarifying that those were real villains. "Thirteen, protect the kids, I'll hold them off," He said before jumping down the stairs and immediately knocking one of the many, many villains out.
Izuku was looking, doing his best to calm his nerves before hearing Thirteen call out to Iida to run for teachers. The mist guy showed up, saying "I'm sorry, I can't let you do that." Katsuki and Kirishima thought the best idea would be to try and rush the metal frame of the villain. Before they reached him, a purple mist appeared in their way and they flew straight through it before it closed behind them again. "I have my orders to torture and kill you, so not resisting will make this marginally less painful," the mist said before engulfing all students in a mist, sending them to different locations.
Looking down, he saw the water moments before crashing straight into it. After his eyes took a moment to readjust, he saw a shark villain coming towards him. Izuku carefully made sure the lightning wasn't arcing around him and powered up his legs in an attempt to get out of the water, when he saw the shark get kicked and a tongue wrap around him. Ignoring the weirdness of the situation (it was a world where almost everyone had a superpower, so that wasn't really too hard), he was launched flawlessly out of the water and gently placed on the boat as Asui landed next to him.
"Asui-" Izuku started before being cut off.
"Call me Tsu." The frog girl cut him off
"R-r-right, Tsu, thanks for the save back there."
"It's no problem. I saved the diaper boy as well... unfortunately," she muttered the last part, before gesturing to the purple... haired kid slumped over in a corner next to her, "he still has the audacity to try stuff."
"Let's just ignore him for now," to be fair, everyone wanted to do that permanently, not just Izuku, "We're trapped on this boat, surrounded by water villains and need to get back to the middle."
"Do you have any ideas Izuku?"
"Well, I don't think they know your quirk, otherwise I highly doubt you would be sent to what is effectively your element, so we have that on our side at least."
"Yes... that is true. How does your quirk react with water?"
"Good question. Shall we let the villains be the first to find out?"
"Sounds fair to me. I'm not carrying the grapist though."
"Grapist?"
"Grapist." She responded with a smirk. Izuku sighed and relented, taking the 'Grapist' under one of his arms, as they prepared to electrocute the water.
Summoning about a small about of his charge, he could feel his hair stand on end and the lightning arc off of him as he carefully directed the charge, first through the ship and then into the water. Once he felt it reach water, he gathered the remaining charge and opened his eyes, which now shone a brilliant emerald green. "Discharge, intensity 2," He uttered, a relatively weak move that would be powerful enough to incapacitate the villains in the water long enough for them to make it away.
The arcing around him subsided as his move wore off, and his eyes returned to a darker green and his hair became floppy. He nodded to Tsu, who lifted Izuku (who was holding Grapist) with her tongue and jumped back towards the centre, to be greeted by a terrifying sight.
In front of them, a large creature with a beak of a mouth and parts of its brain sticking out had pinned Aizawa-sensei down, who was looking worse for wear. Whilst neither the creature nor the other villains had noticed the students yet, they wouldn't be able to do anything from their paralyzing fear.
Bakugo and Kirishima found themselves in an abandoned building, surrounded by various low-level villains. Kirishima was about to start saying something, when Bakugo's hands started crackling with explosions. "Less talking, more exploding the villains!" Bakugo stated, somewhat excited to not need to hold back so much. Kirishima sighed, hardening his hands and turned his back to the explosive boy, prepared to take the other side. "Let's get going then!"
Izuku's gaze was focused on Aizawa-sensei's right arm, which had visible muscle fibers and was bent at a highly unnatural angle. He began collecting some of his lightning, preparing to shock the bird creature when he heard the mist begin talking. "Tomura, I let one of the students escape. I apologize for my incompetence."
"Kurogiri, if your quirk wasn't so important I would've dusted that metal frame of yours by now," the other villain, Tomura, responded. Covered in dismembered hands was a unique look, but he was definitely a villain regardless, "The teachers will be showing up soon, and then its game over. We won't even fight the boss. Guess we'll just have to kill off some of the minions." Tomura finished off, a scary glint in his eyes as he turned towards Tsu.
In a flash of inhuman speed, Tomura was in front of the trio from the flood zone with his hand shooting towards Tsu's face. Thinking quickly, Izuku moved his charge from his legs to his hands and caught the villain's wrist before it could get closer. Sending the charge through his hand and into the villain's wrist, causing a screech of pain to come from them.
Izuku watched as Tomura flinched, pulling his hand away from Tsu. Izuku, running on adrenaline, moved his charge back to his legs and kicked the villain in their stomach, once more releasing some charge into the villain's body. Tomura, was propelled further away and hunched over in pain, twitching slightly as a result of the lightning attacks.
Noticing the condition Tomura was in, he decided that he was sufficiently incapacitated and focused back onto Aizawa-sensei's position, where he was still trapped underneath the bird monster thing.
He probably couldn't safely electrocute the creature in particular without also affecting Aizawa-sensei, but he wasn't sure what else to do. His mind was being powered by his quirk as he watched Aizawa-sensei try to escape, only to have his head beaten into the ground. Izuku knew he personally didn't have the skill or experience to be able to successfully fight off any villains stronger than the cannon fodder, but Aizawa-sensei definitely would.
'All my knowledge and even with my quirk helping my brain I can't assist Aizawa-sensei... wait' Izuku suddenly realized how he could help Aizawa-sensei without risking them in the process, or at least, there was less chance of injury as a result.
Returning his charge back to his feet, he carefully established a connection between Aizawa-sensei and himself. Feeling the power flowing from himself to Aizawa-sensei, he quickly became aware that he wouldn't be able to do much else whilst this was happening, and wouldn't be able to do much else afterwards. "Tsu, Grapist, I need you two to hold off the villains so I can help Aizawa-sensei!" Izuku told them. Grapist screamed something incoherent at him about avoiding getting involved, but Tsu nodded and took up a fighting stance.
He carefully guided the charge through the floor, towards Aizawa-sensei, and let it fill Aizawa-sensei's body. Carefully he focused on moving charge to the muscles and tendons, hopefully giving Aizawa-sensei the energy, strength and speed he needed to take out the remaining villains.
Aizawa was in tremendous amounts of pain, his head was throbbing and his right arm felt like it had shattered into about a million different pieces. Probably because it was. Ignoring the cynical part of his mind, which was somehow still functional despite his definitely severe concussion, he focused on how to get out of the creature's grasp.
His head was being held by one of the creature's arms, and his right arm was being held behind his back with one of the creature's knees holding him down, the other providing it balance. 'It only has one source of balance... and it's prone to being tipped due to the way I'm being held down... if I could force myself up, I could probably tip it off balance for long enough to get a little bit away.' Aizawa however, knew that plans and ideas are nothing when you don't have the physical strength to go through with it.
He sighed and focused on the situation of his students, watching the problem child incapacitate the hand guy, Tomura apparently, and willed the problem child to not interfere with his own situation. His thoughts were filled with panic as he saw the problem child talking to Asui and Mineta, one of whom took up a fighting stance and the other started panicking, and watched as the problem child's eyes started lighting up and his hair stand on end, a clear sign his quirk was activating. He was about to yell at them as he saw their legs start having lightning arc off, but was relieved when the problem child remained in one position, although incredibly confused.
Out of the corner of his eyes, he saw familiar green lightning arc off his own body, as Aizawa looked at the problem child, who responded with a nod. Suddenly, he felt energy course through his body as he himself felt like his adrenaline just kicked in tenfold. He tried to move to push off the monstrosity, to find his own limbs all arcing with the green lightning. He pushed the monstrosity off of himself, to find it remarkably easy. He followed it with a quick kick to the monster's stomach, which felt faster and stronger than ever before.
Looking back to the problem child, who's eyes had closed but the lightning and hair still reacting as earlier, he understood what had happened. The problem child had used their quirk to enhance Aizawa, much like the way he had enhanced himself. Aizawa's signature grin returned to his face as he took up a fighting stance, facing the beast in front of him.
Moving fast, he went for a heel kick, expecting it to be blocked by the creature's speed and strength. Surprisingly, he was marginally faster than the creature, if still slightly weaker. Using the creature as a springboard, he jumped back and returned to the fighting stance. He didn't know how long the kid could power him, and so had to beat this creature ASAP.
Running in again, he went for a left hook to the creature's ribs, which hit, but still made no effect on the creature. "Haha..." Aizawa heard Tomura laughing (who was still curled over and slightly twitchy), "that creature's designed to beat, no, slaughter All Might! It has shock absorption and hyper regeneration, not to mention it's inhuman strength and speed!"
'Shock absorption huh. Probably means it has a limit, but I can't rely on this for too long, no idea how long the kid can power me for. I just have to keep it's attention until the other teachers arrive.' Aizawa thought, doing his best to keep the creature's attention. His combat style primarily involved countering his opponent, so with the speed to outpace the creature this was a task easily completed.
After what felt like hours (in reality it was about a minute) of fast paced dodges and blocks, Aizawa could feel the power slightly reducing as his speed dropped slightly and the blocks became less effective. Focusing more on his speed to keep out of the creature's range, he hoped the kid could hold on just long enough for the teachers to arrive.
Izuku watched as Aizawa-sensei's movements became a blur, his enhancement combining with Aizawa-sensei's strength and speed, along with his experience and skill making short work of avoiding the black creature. Normally he would be able to keep up, but he didn't want to waste his mental capacity or energy on powering his eyes to watch what was happening. His feet were losing feeling as the sensation of pins and needles began to travel to his knees.
Leaning on Grapist, as his classmate was still in an absent minded state of panic, and Tsu was helping support him after whacking the last of the villains with her tongue. Izuku could feel his reserves draining fast, as sending enough lightning to sufficiently enhance his teacher over such a distance was exhausting. At least he didn't have to go through the air.
There were a few seeing spots, his vision getting fuzzy as his stamina was running out quickly from the effort and trying to keep his stores from running out. He wanted sleep. So much.
Realizing the complete numbness in his feet, he knew there was only so much longer he could go on. Next stage would be minor nerve damage, not just shutdown. It was repairable, but he would get an earful from Recovery Girl (who was not happy about his slightly workaholic after insisting on going back to class after he had been healed). The teachers needed to come. ASAP.
All Might was furious. He had run into Iida, who was running to get the other teachers, whilst on his way to the USJ after taking a quick break (he probably should've dealt with the bank robbery faster, but the reporters insisted on an interview, albeit brief). Iida very quickly explained the situation, before running towards the school once more. All Might's signature smile was barely there. Preparing himself, he leaped in the direction of the USJ, intent on smashing through the roof.
Crashing through one of the glass roof panels of the USJ, All Might landed with a crater, and quickly took in the situation. A handful of students were hanging around at the top of the stairs, several were emerging bruised from various zones, and a couple (not counting Iida or Hagakure) were nowhere to be seen. He also saw his colleague Thirteen looking worse for wear. Most perplexing was Aizawa, being chased by a large bird... thing, both of whom were moving at blistering speeds, although Aizawa with green lightning coming off of him. If it weren't for All Might's own capabilities, he would barely be able to register what was happening.
"All Might, take over for me!" Aizawa's yell broke All Might out of his thoughts, "this thing has hyper-regeneration, and shock absorption! There are a few weak points at it's head, neck and upper left torso!"
"Right! Everything will be fine now!" All Might started yelling, rushing over to his colleague's side, "Why? Because!" He continued, winding back a starting punch. If it was absorption there would be a limit, and whatever was going on with Aizawa would've started wearing it down, "I AM HERE!" All Might boomed as his first punch hit the creature.
The creature was flung into the wall, and All Might heard one of the villains calling out. "Ah All Might," they started, "Good of you to show up! Meet Nomu, they've been created specifically to kill you in your prime, despite Eraserhead having had already done a number on them! Have fun!" They broke off with a creepy smile, the tips of which visible along the edges of the disembodied hand. All Might's smile never faltered as he wound up another punch, and charged at the creature.
Whilst All Might was trading blows with the creature, Aizawa jumped towards the top of the stairs, gesturing to the students not yet there to come to him. He felt the energy that he had become accustomed to suddenly leave his body, as the green lightning that once crackled around him subsided.
Turning his head towards Izuku, the problem child who was the source of the power, he felt a little sick. The boy, whilst completely fine on the outside, was carried to him by Asui, as the frog girl gently laid Izuku on the ground near him, at the top of the stairs. However it was clear that was not how the boy felt.
Izuku was drained. His head pounding from a migraine (he had been concentrating incredibly hard to carefully manage the lightning), and his legs failing him the moment he stopped using his quirk on Aizawa-sensei.
He vaguely recognized Tsu picking him up and carrying him over to the stairs (with the Grapist not too far behind). He wanted to sleep but his head felt like it would split apart and his legs wouldn't carry him if he forced himself to stand. He vaguely recognized Aizawa-sensei's voice as his teacher was giving directions to students. Uraraka made Izuku weightless and Shoji gently pulled the boy onto his back.
All Might saw from the corner of his eye as the students were gathering together and helping their classmate. It made him smile, which he wasn't afraid to show as he continued to pepper the 'Nomu' creature with powerful punches.
Whilst his colleague had been able to outpace the Nomu, All Might was unable to, only barely keeping up. However, what All Might had that Aizawa did not was decisive strength. Winding up another powerful punch, he could see the shock absorption on the creature had already reached its limits. Aiming at one of the weak points Aizawa mentioned, he launched his fist straight into the Nomu's upper torso. The creature was heavily impacted by the blow, and he watched as it briefly stopped. "Oh," one of the villains started, the one with hands all over it, "it would appear that the shock absorption has already reached its limit. No matter, it can still destroy you despite that."
'Aizawa must have done a lot if the shock absorption was meant to outlast me, yet it has hardly lasted a dozen punches.' All Might thought. His thoughts were interrupted by the villain getting a powerful blow straight into his left rib, resulting in All Might coughing up a little blood. "Ah, it seems Master was right," the hand man started, "you have been getting weaker. We'll make it easier on you and finish you off quicker to save the remnants of your pitiful hero pride." All the meanwhile All Might was blocking and dodging the Nomu's barrage of attacks.
Winding his fist back, he prepared a powerful punch. He was not quite at his limit but he sure was getting close. "Have you ever heard this saying before villain?!" All Might boomed as he prepared to finish off the Nomu creature, "GO BEYOND! PLUS ULTRA!" he finished off as the devastating blow hit the same weak spot from earlier. The creature seemed to pause in time, before being propelled through the air towards the glass dome that encased the USJ.
All Might stood victorious, glaring at the villains who stood before him. The Symbol Of Peace spoke a few words, "Surrender, or be defeated."
"Tomura, we should go," the purple mist spoke, opening up what appeared to be a warp gate.
"Kurogiri, we, we came so close to beating the final boss," Tomura began, "but we have gained experience and we know what to bring next time. Next time we see you All Might, we will end the so-called 'Symbol of Peace'."
The two remaining villains walked through the warp, leaving All Might to return to the stairs as the remaining teachers showed up to help clean up the mess.
Bakugo and Kirishima had finally worked their way out of the building, they quickly went back to the centre to be met by an interesting scene. All Might had just punched a bird creature through one of the panels of the USJ, and the hand villain and mist guy just walked through one of the mist guy's portals.
They quickly ran past All Might, and up the stairs to find Izuku being carried by Shoji, Aizawa-sensei looking ever so slightly less pissed off than usual, and the other teachers doing their best to help the other students. The spiky haired blonde and spiky red head looked at each other, with only one question, "What the fuck just happened?" (swearing courtesy of Bakugo).
"Izuku has a migraine from quirk overuse, Aizawa-sensei was holding off that monster thing until All Might showed up, and everyone was scattered to various locations," Yaoyorozu answered, "You guys are the last to arrive."
"Wait wait wait, so Aizawa-sensei was holding off that monster thing that All Might was struggling with?" Kirishima asked.
"Yes, we can discuss that some other time. First, let's go back to the main campus, and make sure Recovery Girl looks over you all," Principal Nezu interjected, motioning towards the door as the other teachers assisted the injured.
Bakugo, Kirishima and a few other students were left uninjured, but Bakugo was really worried for Izuku. Izuku looked like he was about start screaming any moment, his eyes squinted and hands over his ears. "Hey Yaoyorozu," Bakugo started, startling the black haired girl, "can you make like, some industrial grade earmuffs and a blindfold?"
"Uhh sure, but why?" Yaoyorozu responded, surprised by the gentleness of Bakugo's tone. The boy, in response gestured to Izuku. Yaoyorozu handed him the items, and Bakugo reached over to Izuku in order to place the requested items on the green haired boy.
Bakugo heard an audible sigh of relief and a whisper of thank you, and he turned back to Yaoyorozu with a proper explanation. "His migraine from the quirk overuse is never minor, because if he forces himself past the point of just tiredness, he's probably going to go all the way."
"Yeah that makes sense, but since when could you be so gentle and kind?" She replied, genuine curiosity in her eyes.
"Why is that a such a fucking surprise to people!" Bakugo whisper yelled back. Yaoyorozu's response was a shrug. She opened her mouth to speak, to be interrupted by Aizawa-sensei announcing their return to the main campus of U.A.
Bakugo watched as his brother was carried off by Shoji in the direction of the nurse's office. He wanted to follow, but was told by Aizawa-sensei to return to class for the last hour of the day. The man had already seen Recovery Girl for his own injuries, and was stubbornly refusing to take the remainder of the day off. Bakugo opened his mouth to speak, but Kirishima placed a hand on his classmate's shoulder. The blond boy sighed, restless to check on his brother, and shouldered the hand off before someone else's hand was on his other shoulder. "Izuku needs quiet and rest, right?" Yaoyorozu started, "There probably isn't much more you can do, and being with him won't solve anything."
"Yeah... alright then," Bakugo relented, "you can let go of me now." Yaoyorozu complied, and Bakugo started making his way towards class.
Aizawa-sensei sighed as he watched the class file in. Other than Izuku, all of the students were in a state of mind where they could process what was happening (Kaminari had recovered since his use). Izuku was suffering from extreme migraines and a nervous system overload in his lower body (it was only temporary, but Recovery Girl said that if it were to happen to a similar extent too many times there would be lasting effects).
Once every seat was filled, he took a breath and asked the class if they had any questions. Immediately a dozen hands shot up. He sighed again, pointing at Hagakure's glove, and started answering their questions.
By the end of the impromptu questionnaire, the class had learnt several things.
1) Quirks can be incredibly versatile if you're creative enough
2) U.A can be dangerous
3) Aizawa-sensei was a god-damn badass, he might be lacking in raw strength from a quirk but he had skills that made him a force to be reckoned with.
Aizawa sighed as he dismissed the class for the week, as it was Friday. There was an emergency meeting with the teachers as soon as school was finished, and he headed to the staff room for whatever Nezu wanted. Aizawa just wanted sleep.
The moment class was done for the day, Bakugo ran straight out the day and towards the nurse's office. He made it to the entrance, before being blocked by Recovery Girl. "I know you are concerned for your friend, but-" Recovery Girl started.
"He's my brother, now let me through so I can take him home!" Bakugo cut her off, barely holding back his tongue.
"He'll be staying overnight," Recovery Girl told the firey blond sympathetically, "and he'll be back at your place tomorrow, probably around ten in the morning after I give him something to eat and run over a couple final tests. Right now he just needs peace and quiet, and I've gotten Cementoss to cover the windows in one of the rooms so he'll be alright there. For now, just head on home, I think you have some friends waiting for you." She finished, pointing in the direction of the gates. Bakugo gave the nurse a glare, as though he were about to argue, but knew it would be pointless. He nodded to her, before turning to the gates to walk home. Their mother is going to be annoyed, if undeniably proud.
