[Unforeseen Simulation Joint, April 13th, 2243]

Izuku sprinted along the outskirts of the plaza, carrying Hagakure in his arms. He slowed as he reached the halfway mark, ducking behind the trees near the entrance to the ruins zone. Hagakure was still passed out so he had to keep going.

"Midoriya? Is that you?" He heard a familiar voice call out. On the path ahead, he spotted Shoji and Kirishima helping an irate-looking Bakugo as he limped along the path.
"You guys are alright!" Izuku cried.
"Calm the fuck down Deku!" Katsuki snarled, wincing as he put his weight on his injured leg.
"Bakugo, you're hurt?" Izuku noted.
Katsuki narrowed his eyes, still unused to Izuku not using the childhood nickname. "Fucking sniping bitch… I'm fine!"
"He broke his leg," Eijiro explained, earning a sharp glare from the explosive blonde.
"Shut up Shitty Hair, I didn't ask for your help." He snapped. "I just don't want to worsen the injury." Fuckin' Deku, of course he wasn't hurt at all. "What the hell's wrong with her?" He motioned to… what was that extra's name again? Formerly invisible girl?
"She figured out how to use her quirk and defeated one of those armored villains," Izuku replied.
"Here, I'll hold her." Mezo offered, growing extra arms. "I can still fight with my quirk, you can't."
Katsuki glanced at the taller boy. "You better not be thinking about carrying me Facemask."
"Shoji."
"Whatever." Kastuki huffed. "Let's get the fuck out of here."
The group made their way alongside the outer ring, peeking over to see Eraserhead fighting off villain after villain.
"Look!" Eijiro whispered, pointing to the warping villain who had just reappeared.
"He's not up there anymore…" Shoji murmured. Did that mean he… no… best not to think about that.
"They're fine," Izuku assured him. They had to be fine. He remembered seeing Haylee escape the warp gate when he fell. If anyone could keep his classmates safe, she could.
Still barely hidden by the brush they continued to make their way to the staircase, every so often sparing a glance to the center to make sure they hadn't been spotted.
"Hold on, look!" Shoji whispered.
"Mr. Karris…" Izuku put a hand over his mouth. The man looked terrible, as if he were steps away from death. Between their senseis and the villains, the large bird-heteromorph stood among a field of craters, having just attempted to smash Ordan to bits.
They couldn't make out what was said, but Karris-sensei's body suddenly began to shake. The calcified hero twitched as bones began to sprout from his body, and with a beastlike howl, he threw himself at the villain.
CRACK!
Before he even had a chance to strike the villain punched their new teacher into the staircase, their destination.
"No!" Izuku cried out.
"Midoriya, wait!" Mezo grabbed Izuku's shoulder with his quirk. "We need to go!"
At the top of the stairs, a flare was launched through the hole in the roof that they hadn't noticed before.
"But-"
"We're just students!" Mezo warned.
"But we need to-" Izuku protested.
"We'll get Karris-sensei on our way up! C'mon!" Eijiro pointed to their downed teacher.
Izuku's gaze darted to Ordan, then to Aizawa-sensei. The big villain had grabbed their teacher and had begun to break his limbs. The Erasure Hero's screams echoed through the plaza. "I can't… I have to!" Before he ever realized it, he was sailing through the air, One For All surging through his body.
"Midoriya!" Mezo and Eijiro shouted in alarm.
"Dammit Deku! You're going to die!" Katsuki hollered.
"SMAAAAASH!" Izuku screamed, punching the villain as hard as he could.

The other boys were nearly knocked off their feet by the wind pressure generated by Izuku's punch. Bunker's Snowglobe quirk protected the other villains, though it did slightly crack before mending itself.
"What the hell…" Katsuki gaped at the sheer power Izuku had just unleashed. Was he really that far behind the nerd now? Damn that villain, he could be out there fighting if not for her breaking his leg. Who was the useless Deku now….

=VI=

"Smash, huh?" Tomura queried. "So you must be one of All Might's disciples." Could he be the one Sensei warned him about? The one that All Might passed his damnable quirk to?
"M-midoriya…" Shota wheezed. "Run!"
"Let him go!" Izuku pointed his blade at the villain. "I- " He gulped, steeling his resolve. "I'm only giving you one warning!"
"Nomu! Kill the sword brat!" Tomura demanded.
The villain, Nomu, charged at Izuku with zero hesitation. Eraserhead was momentarily forgotten and tossed haphazardly to the side as if he were a piece of trash.

Izuku was able to see the blow coming and with but a moment's hesitation- attempted to sever the villain's arm. 'I'm sorry…'
But as soon as his blade made contact with Nomu's skin, it snapped in half.
'Huh?!' Izuku blankly watched the blade shard fly past him in slow motion. 'It… broke? I hit him just like Haylee taught me. Did I mess up? No... It's not the sword… Nomu's skin is too strong!" In just a second he could already tell that Nomu had some sort of damage-reducing quirk. Izuku didn't have time to ponder the issue further, dodging the Villain's next strike with a One For All-powered backdash.
Nomu kept on coming, relentlessly slamming his fists into the ground where Izuku was standing like he was playing whack-a-mole. Izuku could only keep evading thanks to One For All enhancing his reaction time.
But every second that Nomu was focused on him meant another second that he wasn't killing Mr. Karris and Aizawa-sensei.
"Why the hell isn't he dead? These are supposed to be level one trash mobs." Tomura growled as the green-haired brat kept dodging. "Fucking I-framing little shit! Kurogiri, bring in the rest of Scrambler's men!"

"I apologize, but they all seem to be incapacitated at the moment, or dead," Kurogiri replied after a few seconds of looking through his network of portals. He glanced at Fania to ascertain her reaction. She didn't seem that bothered, looking more annoyed than anything. "Scrambler, are you not concerned about the loss of your men?" Kurogiri asked.

"Of course not. They're trained soldiers and mere teenagers are defeating them." Fania scoffed apathetically. "Plus, they're only Grineer." She stiffened, not having meant to let that slip.

"What the fuck is a Grineer?" Tomura asked.

"I will tell you later," Kurogiri said, focusing back on Nomu's fight.

Fania eyed the warp user suspiciously. Why did he- who was Shigaraki's servant, know about the Grineer while his supposed master did not?
"Whatever…" Tomura scoffed. 'Damn hero brats! They were fodder but you should've been easy to take down!' Nothing about today was going to plan. The only thing he'd accomplished was injuring the teachers, and his greatest weapon was chasing around some stupid kid.

=VI=

As Izuku kept evading, he noticed that Nomu's attacks were telegraphed- as in they were literally just obvious punches that he could see coming a mile away. Okay, not a mile. They were pretty dang fast and his quirk was the only reason he was alive. Nomu didn't have any technique, only raw power.
Izuku could deal with raw power. Nomu had already withstood his first punch at five percent without even flinching. 'One For All: 10%!' His fist crackled with energy. "SMASH!" He landed a punch to Nomu's liver.
He didn't budge. Izuku's punch had been negated.
"Hahahaha!" He heard Shigaraki giggle from across the plaza. "Stupid brat, Nomu has a Shock Absorption quirk! He was made to fight All Might, what makes you think that you can hold a candle to that!"
'I was right! He does have a quirk that stops punches! Wait, did he say "made to fight All Might?'
Before the hand-covered villain could continue, a wave of ice enveloped Nomu and froze him up to the chest.
"Todoroki?" Izuku whirled around to see his classmate collapse from quirk exhaustion following that attack.
"Midoriya!" Ordan called out, supported by Inosuke and barely clinging to his his regained consciousness. "It's not human! Don't worry about holding back!" He wheezed, coughing up blood.
"Not… human?" Izuku stared in horror at Nomu as it tried to tear itself out of the ice. The creature's sudden body movements caused the its frozen flesh to pop and tear open, oozing dark red blood that smelled of antiseptics.
"Nomu! What are you doing? Kill him!" Tomura commanded.
With a roar, Nomu began to break free, putrid chunks of frozen flesh breaking off of his body and immediately regenerating. Izuku felt a sharp pang in his head and instinctively lashed out with all his might, punching a bowling ball-sized hole clean through Nomu's chest. He ignored the bile rising in his throat, laying several more punches into Nomu while it continued to regenerate. The creature moved robotically, ignoring his punches as they weren't dealing lasting damage. Izuku's punches combined with Nomu's struggling proved to be enough for it to break out of the ice, after which it immediately launched itself at Izuku.
'One For All: 25%!' Izuku channeled as much power as he could into his right arm and decked Nomu with an uppercut, merely causing it to flinch. He felt a sharp pain, having broken every finger in his hand with the blow.
"No way…" He took a fearful step back. No matter how hard he tried Nomu just wouldn't budge. Even using his maximum output with One For All could only cause him to barely feel it, and he'd broken his bones again.
Tomura cackled to himself. That boy was no All Might. Even if he was the potential successor that Sensei had warned him about- Nomu would tear him apart. Nothing would hurt the symbol of peace more than knowing the holder of his quirk had been killed while he was absent. Noticing that Nomu had neared the downed Eraserhead again, Tomura had an idea. "Nomu, I want you to grab Eraserhead."
Nomu complied mindlessly, instantly ignoring Izuku and sprinting over to Eraserhead, who had recovered enough to begin crawling away. It grabbed the battered and bloodied hero by the head and lifted him up with a single arm.

"Sensei!" Izuku cried out in despair.
"What's wrong little hero? Aren't you going to save him?" Shigaraki cackled at Eraserhead's loud groans of pain as Nomu began to squeeze his skull. "Your teacher is going to die if you don't help him!"
'My sword couldn't break through it's skin… and it withstood multiple hits from One For All. But I can't just stand here and let Aizawa-sensei die!' Izuku tensed defiantly before Nomu even as he shook in his boots.
"Nomu! Kill them!" He heard Shiagaraki's voice ring out. Nomu raised Aizawa up in one hand, letting out a screeching battlecry as it threw an unavoidable punch at Izuku with the other.
Time slowed down as the fist inched its way ever closer…

[Ground Omega]
"Thanks for helping me out Fuwa." Haruki finished setting up his robot. It was a small U.G. unit based off a falcon, designed to assist heroes in reconnaissance and finding disaster victims.
"No problem!" Mawata fidgeted. "Uh, Power Loader-sensei said that you needed someone with you if you were going out to the training grounds, so I volunteered."

"But still, you didn't have to. I could've waited for one of the other support students or teachers." Haruki set down the control panel and pushed up his glasses. "I really appreciate it though."

"Well, uh… would you really want someone like… what was her name, Hatsume?"
"Yeah."
"Would you really want someone like her helping you out? You talk about how much she stresses Power Loader out all the time." Mawata mused.
Haruki opened his mouth to protest, then lowered his finger. "That's a fair point. Maijima-sensei and Furasu are barely enough to keep her from blowing up the labs every day." He chuckled. "And god forbid I try and get Kenranzaki to help me." The brown-haired teen shivered, imagining the blonde third-year riding around on her extravagant mech.
Mawata giggled and sat down next to Haruki, idly fiddling with her fluffy earring. She totally didn't volunteer to help him with his project because of her massive crush on him. It wasn't her fault that her support partner was so damn cute!
The U.G. spread out its wings and took off with a quick firing of its engines until it was dozens of meters in the air over the plateau they were sitting on.
"So, how does it work?" She leaned in closer to his laptop, causing him to blush.
"Well, it's basically just a drone that works like a bird, so it can ride wind currents. It's lightweight and easy to produce- the only really expensive parts are the artificial intelligence and computing components."
God, he was so dreamy when he started yapping about his gadgets.
"... and its range is about five kilometers before the range gets spotty, not bad for the parts I used. The real beauty of it is the detection. It can locate heat signatures and highlight their location for you if you are wearing a visor, live of course. I uh, haven't made the visor yet, but you can see what it would look like from the drone's view." He pressed a few keys and the screen changed to show the drone circling above with the two of them highlighted in green.
"Woah…" Mawata gasped.
"It's not that impressive, the military probably has stuff that can do this and more." He downplayed his achievement.
"Well, you made it by yourself, so I think that's pretty cool." Mawata smiled, twirling one of her bangs around her finger.
Haruki's face heated up and he looked back at his screen, clearing his throat. "Uh-anways-wanna-seeme-find-some-animals?" He stammered.
"Sure." She nodded.

"Okay, so I didn't really calibrate it for animals, so it will only show dead and alive ones." He pointed to a highlighted deer on the ground as the camera swept over the area. "Like that one is healthy, oh- look, there's a dead animal there." He moved his mouse cursor over a red dot.

"What's that one in the sky?" Mawata pointed at the bright red one in the air in the distance.
"Huh?" Haruki leaned in closer. Red was injured, but nobody would be injured in the sky… was it a bug? Out of random curiosity, he glanced over to the area, where the USJ could be seen in the distance a few kilometers out. In the sky, a glowing red object could be seen. "No, that's whatever that is." He directed Fuwa's gaze to the west. "What is that?"
Mawata's eyes widened. "That's an emergency flare!" Why was there one over the USJ? She was pretty sure that they didn't train on campus with those… was Kurose-sensei doing
The second flare shooting up a minute later was what made her dial the emergency school number.

[USJ, Entrance]

After a minute, Momo launched another flare through the hole. Even with quirk exhaustion setting in, flares were easy to produce. She'd keep firing them off until help arrived. As the explosions and crashing sounds from the plaza got louder, the students grew more concerned.
Even more so when Bakugo, Kirishima, and Shoji- who held Hagakure in his arms, reached the top of the stairs.
"What's going on?" Ochaco asked.
"Fuckin Deku is fighting the villains, the idiot is going to get himself killed!" Katsuki collapsed, allowing his injured leg to rest. If that villain hadn't shot him, he'd be down there fighting alongside Deku, but he was relegated to limping around like a injured deer.
"Izuku!" Haylee sprinted past Bakugo, followed by Uraraka. Upon reaching the stairs, she froze.

Izuku stood in the middle of the plaza, surrounded by craters and clutching his injured arm. Hashibira and Mineta were struggling to drag a battered Ordan and unconscious Todoroki up the stairs, mostly due to Ordan trying to claw his way back to the battlefield.
"Fania…" Bunker nodded his head toward the stairs, spotting the Tenno girl. His wife tensed, reaching for her pistol.
Nomu lifted Aizawa up by the skull, an audible crack echoing throughout the center of the USJ.
Haylee's breath hitched and her vision grew blurry.
"One for the reject pile, then." Erra scoffed, simultaneously crushing Teshin's skull and snapping his neck.

Haylee wasn't fast enough to exit transference, blasting Erra a second too late.
Haylee began to hyperventilate, hands shaking- the memory of Teshin's death superimposed over Nomu's towering form.
'No no no no… It's happening again… he's going to die!' Aizawa had only been her teacher for less than a week, his methods were odd and he napped whenever he had a free moment that didn't require teaching, but he had the no-nonsense attitude that reminded her so much of Teshin.
The memory of Teshin's death kept replaying itself over and over in her mind. Too slow, watching as yet another person she had grown to care about was taken away before her very eyes.
'I'm not strong enough to tank a hit from that… No… that thing might even be a match for All Might!' Haylee realized, sensing the overwhelming strength coming from the creature. 'If I don't do something, they are both going to die… Is Excalibur strong enough?' If Nomu really was as strong as All Might, all it would take is one or two good hits to take her down.
Haylee tuned everything out, barely hearing as Uraraka called out Izuku's name, nor did she hear Shigaraki's command to the monstrosity. Everything slowed to a crawl as Nomu raised its fist, squeezing Aizawa-sensei with the other.
'I won't lose anyone else…' She began to transform, skin burning with the same rage she felt in her soul. She didn't register the surprise at suddenly feeling pain, dedicating everything she had to reaching Izuku. She landed at the bottom of the stairs with a loud boom before launching herself forward, already mid-transformation. 'But it doesn't matter! I won't let this happen again!' Her flesh hardened and bulged as she charged forward. "NEVER AGAIN!" She screamed.
Bunker took a terrified step back, nearly collapsing due to his injury. "Another Warframe?!"
"She can turn into more than one!?" Fania gasped.
Izuku was frozen in place as Nomu's fist closed in. Unable to dodge, he raised his arms to block the blow. "Oh no-"
Iron Skin!
CLANG!"Haylee!?" Izuku gasped. He knew it was her, even though her form was larger and more muscular.
"Huh?!" Tomura gawked, confused at the male figure who had just taken Nomu's punch. 'Nomu didn't damage him?'
Shota wasn't sure what was going on, but felt something grab his leg and then he was flying into Midoriya's arms."Izuku, get him out of here!" Haylee yelled, her voice far deeper than in her Excalibur transformation.
"Sensei!" Izuku caught him, bracing as not to exacerbate Eraser's injuries.
Nomu lunged at Haylee, who took another punch without budging an inch. With Nomu's guard exposed, she felt all the stored up energy from her fight with the Corpus surge throughout her body. In that moment, she visualized the perfect window of attack.
"TENNOKAI!"
Haylee's fist slammed into Nomu's chest, releasing a burst of violet energy into the monster's body. Nomu flailed as it was sent flying across the USJ, a faint glow dancing across its skin. It made it about halfway across the facility before breaking free of whatever had trapped it, slamming into the cliffside of the mountain zone crash.
'Is it down?' Haylee panted.
Tomura was livid. "Impossible!" He howled, beginning to throw a small tantrum. "Nomu has shock absorption that can handle All Might!" The hand-covered villain began to viciously scratch at his neck until it was raw in several places. Having heard the newcomer's voice, he realized it was a girl. "She's a damn cheater! How did she do that? Was it that glow?" His voice cracked, not understanding what was happening. "NOMU! KILL THAT GODDAMN CHEATER!"

Nomu slowly shrugged the rubble off its shoulders, brushing off the dust as it emerged from the cliff face.

"Izuku, I'll buy time. Take Sensei and go!" Haylee commanded.
"Haylee…" Izuku choked up, hesitating. "Can you beat him?"
Haylee stayed silent but gave him a slow nod. "Now go!"
Nomu charged toward Haylee, who met the creature's fist with her own. Neither budged.
Haylee didn't know if she could beat Nomu, but by the Void she was going to try.

=VI=

Next time: Chapter 53, Unstoppable, Immovable! The USJ reaches its climax!

Haylee has Rhino now! The perfect matchup to Nomu as they both (essentially) have the same ability.
