The three are pinned to the spot, pure terror written on their faces as they watched the scene just in front of them. Midoriya, Tsuyu, and Mineta all watched as the prototype Nomu smashed into their teacher's face, him being brutally pounded into the ground as he attempted to erase the beast's quirk. The man, after identifying himself as Shigaraki, explains how it is a complete waste of time to try and stave off the Nomu. He claimed that its strength wasn't a quirk and that the beast is the holder of multiple quirks, making him strong enough to withstand All Might's punches.
Midoriya was the first to move and went to punch the Nomu with 100% of his quirk. He did not heed his knowledge about the drawbacks of it in hopes to injure the monster as much as possible.
Immediately a towering, purple, warp gate materialized right in front of Midoriya as Shigaraki's hands were reaching for his face. Just when everything seemed to fall into slow motion, a shout snapped Midoriya out of his head.
"Out of my way, Deku!" Bakugo screamed as he took hold of Kurogiri, pinning him down by his steel neckpiece.
All Might, who arrived at the scene not long ago, instructed the students to evacuate. Though they did not listen, wanting to help out their friends and the hero.
"Kurogiri, I would kill you right now, but you're our escape route. Nomu." Shigaraki spat out with derisive venom. He commanded the Nomu with a calmness that betrayed his anger.
With that one word, the beast moved at a speed that was hard for the human eye to keep up with, and appeared directly in front of Bakugou, shocking him. Bakugou tutted in irritation, not having nearly enough time to dodge as the Nomu brought down its meaty fist. A sudden gust of smoke and dust blocked everyone's view. In an instant, a confused Bakugou was now standing beside Kirishima, Todoroki, and Midoriya, far from where he had been previously.
Kirishima was amazed that Bakugou was able to dodge the powerful blow, however Bakugou confirmed that he in fact did not evade it. Whoever it was, they were thrown back from the herculean strike as they crashed into a wall, making a purchase with a plume of dust and cement. In Bakugou's place stood their classmate, Madara Uchiha, who held both of his arms out in front of him, seemingly having protected him from the hit. Madara felt his body was a bit shaken from the punch, feeling the weight of the Nomu's power.
'Even with just about 10% of my strength in this feeble body, that thing was still able to throw me back further than I anticipated.' He thought to himself, feeling his arms throb a bit.
"Young Uchiha!/Uchiha-San!" Both All Might and the four students shouted frantically at his sudden appearance.
Lowering both of his arms, he bobbed his head in affirmation, proving he was alright. He slowly straightened to his full height, his chin lifting in condescension at their opponents. With his right hand, he began to swiftly sweep off any dust that had gathered on his shirt. Shigaraki, frustrated at the blatant disrespect and the unexpected results, he scratched his neck fervently. The group was completely silent as they beheld in pure awe what had just occurred.
"You don't know how to hold back a punch, even when it is just a child!" All Might exclaimed suddenly, conveying his anger with his sharp tone.
"Your student had my comrade trapped. What was I supposed to do, hold back? Yet you go full force on me, it just isn't fair now is it?" Shigaraki questioned All Might mockingly, standing with both hands outstretched, twitching sporadically.
All Might immediately grabbed Madara, placing him down with the other students, after which he prepared for the next hit from the Nomu. Not even seconds later, both powerhouses exchanged hits, going back and forth, not even stopping to catch their breaths.
"Amazing! I can't even see their strikes!" Kirishima stated excitedly as the five watched the battle before them.
"Are you okay, Uchiha-san?" Midoriya questioned as he walked up to him, worried since he took a blow from such a beast directly.
"Tsk." Midoriya flinched as Madara gave him an icy glare. Midoriya waved his hands around nervously as he apologized for angering him somehow.
"PLUS ULTRA!" All Might drew back his fist, delivering his final punch, sending the Nomu flying out of the building's glass roof.
"No, No, No! This wasn't supposed to happen he told me-" Shigaraki stepped back, frustrated as his red eyes showcased pure hatred and fury. Kurogiri, now by his side, calmed him down reassuring him that it wasn't over. The villain group, who had all been knocked out by Aizawa, began to regain consciousness, rising again.
'Damn it! My form won't last any longer.' All Might thought, standing still as the smoke was slightly obscuring him from everyone's view. Blood dripped down his chin in rivulets before he wiped it clean with his fist, facing back towards the villains. Having no other choice, he began to bluff at them, standing in place intimidatingly, hoping they will take the bait and leave.
As if the gods answered him, Shigaraki began to complain, instructing his companion, Kurogiri, to make a portal to leave. That was only after he had reassured Shigaraki that they had the clear upper hand in this situation and pointed out how the previously knocked out villains were now slowly regaining their consciousness.
'They're not wrong about them having the upper hand in this situation. It seems that All Might is at his limit.'
During the fight, Madara noticed how the Nomu specifically targeted one spot on All Might when he was captured in its grip. It was just the left side of his diaphragm, right on the rib cage. Its nails were digging to his sides harshly in an attempt to weaken him. Yet it didn't seem right. If the Nomu wanted, it could've just targeted his legs or his arms, but it went with something else.
It seems that the number one hero might have an injury and it was kept out of the public view of the people. Madara watched from the sidelines, observing as All Might called out to the villains, clearly bluffing about how they had the upper hand and they didn't. Shigaraki, fed up, went to attack, only to be stopped when two bullets pierced his skin. Kurogiri on high alert, covered him with his warps, slowly but surely teleporting them out of the USJ and into their hideout.
The majority of the students now had tears in the corners of their eyes, clearly grateful that backup had arrived and that they were safe from danger. The loudmouth hero, President Mic, walked near the edge of the stairs as he released a loud scream.
"YEAHHH!"
The students were quick to cover their ears as a few villains were holding their ears in pain as well. The R rated hero, Midnight, walked forward pulling her costume down, revealing her skin as it produced a pink fragrance, which knocked out the remaining villains who weren't affected by President Mic's loud shout. On top of that, the weird cowboy looking man, Snipe, aimed his guns into different locations as he shot down his targets, the few remaining villains hidden from sight.
Relieved by this, the students began to celebrate, knowing they were saved. On the other hand, Madara was extremely annoyed at his own weakness. His arms were numb from the hit.
'That punch was like a love tap from my father, and yet I'm affected this much? It seems I need to train this body much more.'
Cementoss created a wall of cement separating All Might and the rest. Midoriya was the only one who was on All Might's side of the barrier, which seemed rather suspicious but no one paid any heed to it. Kirishima, concerned about this, asked Cementoss why he did so. He stated that he had to be cautious around the villains, indirectly saying they couldn't speak now. Understanding the situation, Kirishima gave him a thumbs up and told the other three that they needed to clear out the area.
Madara closed his eyes, forcing his arms and shoulders to relax, knowing it would be best to keep them still rather than moving them around to prevent further injury. This body was a lot weaker than he anticipated it to be. If only he had his original body, then he wouldn't have had the need to hold back instead of fighting. He'd rather fight someone that was capable of withstanding his might. After all, there had to be someone out there who could satisfy his desire other than Him.
-Somewhere Else-
Unknown POV:
"Achoo!" He held back a sniff as he felt a cold shiver go down his spine. He trembled slightly not expecting to sneeze, as this led him to reveal his current spot to his 'enemies'.
"Elder brother, it is wise to not make any noise during a battle, despite it being a fake mission." A stern voice echoed.
"Sorry!" He meekly replied, quickly apologizing as he refocused completely on the mock battle.
'I wonder who's talking about me?'
"Achoo!"
'Crap!'
"WHAT DID I JUST SAY!" An angry voice boomed.
