Time for Chapter 15. Last time Gizon and Ochaco tired their hardest to hold back Nomu from killing everyone. But they efforts were not effective, as they learn the truth behind the creature. Ochaco might have been told by All Might, but how does Gizon know. This time it's All Might's tun to take a crack at the monster. Will Gizon and Ochaco's fight weakened the creature, or will All Might need some extra help with time.

As always I do not own any right to MY HERO ACADEMIA or Marvel or any of their characters.

With that, let's begin.

Toshinori had feared the worst when Ilda ran into the Teacher's lounge. He had wished for anything to happen to get out of Principal Nezu's lecture, but not something like this. He was still in his deflated state, so in his panicked state, Ilda didn't pay him any attention. Toshinori had to stop him from giving away his identity.

"Principal Nezu, the USJ is under attack. Villains broke in and attacked…." Illda began to explain the whole situation, but Principal Nezu cut him off.

"Mr Ilda, that is all we need to know. I'll inform the teachers," Principal Nezu said.

"But sir. Where is All Might?" Ilda asked, looking at Principal Nezu with much fear in his fears. The last few minutes had been very stressful for him and he need to know everything was good.

"Fear not, Young Ilda, he is much closer than it appears. Start running back to the USJ and I'm sure he'll catch up," Toshinori said, Ilda finally looking at him.

"Yes sir," Illda said, then took off.

Toshinori waited a few seconds, then buffed up, "SORRY TO CUT THE LECTURE SHORT, BUT I'M NEEDED ELSEWHERE."

Principal Nezu simply nodded then pulled out his phone, "You'll get there first. Handle whatever is left after Thirteen and Eraserhead." All Might nodded then took off.

He left a dust trail, as he dashed through the hallways of UA. He rushed out of the front door and looked towards the USJ. Without a second thought, he took off, quickly catching up to Ilda, and then shooting ahead of his student. When he arrived at the USJ he found the cracked door Ilda had slipped out of. Unfortunately, it wasn't big enough for him to get through. He quickly threw a punch, and then with a second punch, the door fell in and hit the ground, resonating the sound through the building.

He walked in and saw the mess. Some of class 1-A, along with Mr Aizawa and Thirteen, were on the top platform. His fellow teachers were both broken and bleeding. The students appeared to be fine, but AllMight understood that not all scars were visible.

He looked down and saw Gizon and Ochaco in a crater inside the stairs. Then he noticed a second crater lower down on the stairs. It was clear the two had been through a long fight and were not backing down from injuries. Yet now they were breathing heavily and struggling to stay awake.

All Might looked around and saw signs of fights. In the main plaza, then the different sections of USJ. It was clear the rest of Class 1-A were in the different sections of the building.

All Might's iconic smile dropped to a frown and he yelled, "FEAR NOT STUDENTS, FOR I AM HERE."

"All Might." The students nearby cheered. They all looked relieved to see him. If All Might was here, then the fight was good as over.

All Might looked at them for a second to reassure them, then began to walk down the stairs to Gizon and Ochaco, "WHO IS THE PUNK THAT DECIDED TO MESS WITH MY CLASS."

"Finally the final boss showed up. We can clear this level and move on," Shigaraki said as he was no longer scratching his neck, his whole attention and focus was on the #1 hero

All Might knelt down next to Gizon and Ochaco. Ochaco had used her primary quirks to take the weight off her broken body, while Gizon looked like he was going to break his teeth with how hard he was clenching them, "HOW ARE YOU TWO?"

Ochaco didn't answer, so Gizon said, "We're still breathing."

"WAIT HERE WHILE I CLEAN UP THIS MESS." All Might then stood up and took a stair. However, a strong grip locked his hand. He looked down and saw Gizon holding him back. If the situation wasn't serious, All Might would have been shocked by the motion. With his strength, he had never come across someone that could hold him back with a simple vice grip.

"That Nomu down there has more than one quirk. Shigaraki called them shock absorption and hyper regeneration. There's a limit to how much Nomu can absorb at once." Gizon said, then released All Might. He mumbled something that sounded like 'All for One.' and then passed out.

Gizon's word registered in All Might's mind, who quickly looked at Ochaco, "HE KNOWS?'

"Only about All for One." Ochaco said. Gizon had just passed out, but she didn't want to take the risk of naming One for All in front of him.

"YOU USED IT." All Might noticed the state of Ochaco's right arm and legs. Ochaco had only had One for All for a little over a month now, but she didn't have much control. So All Might had put her on probation until she gained more control, the situation must have gotten to the point she was willing to injure herself to fight.

"Gizon, He-he-he was willing to give his all in the fight against Nomu. Y-yet he was already tired from fighting the giant metal villain. You trust me to be the next symbol of peace, I couldn't let myself fall behind. H-He needed my help," Ochaco said, fighting back tears as forced her thoughts into words.

"I UNDERSTAND. YOU'VE DONE WELL, REST AND I'LL HANDLE THE REST," All Might said, then walked down the stairs, "MY STUDENTS HAVE INFORMED ME OF WHAT OCCURRED IN MY ABSENCE. AND I MUST SAY, IN ALL MY YEARS OF BEING A PRO HERO, I HAVE NEVER MADE A FIGHT PERSONAL. BUT AFTER WHAT I'VE LEARNED, I'LL TELL YOU WHAT I'M ABOUT TO DO TO YOU AND YOUR NOMU. I'M GOING TO ENJOY IT". All Might reached the ground with the last words, cracking forming under his foot from the pressure.

"So the Number 1 hero has a dark side." Shigaraki gave a big smile, "Good. Nomu, kill him."

Nomu and All Might rushed each other. They met in the middle, punching, and kicking, Nomu even bit All Might. Everyone could just watch in amazement as the two Titans clashed. Each blow shook the ground and sent harsh breezes through the USJ. It was impressive the amount of power two people could hold.

"MY STUDENTS INFORMED ME OF NOMU'S TWO QUIRKS. MORE IMPORTANTLY THEIR LIMITS." All Might managed to get around Nomu and lifted him up. All Might proceeded to suplex Nomu into the ground.

However, a portal formed right where Nomus' head would have hit. All Might was caught off guard, even more so when Nomu's up half appeared below him. Nomu reached up and grabbed All Might's side, gripping his finger into All Might's wound.

The sight looks like one out of an old horror story, as blood began to bleed through All Might's shirt. It began to drip from All Might's back and fall to the ground. As All Might struggled to break Nomu's grip, Nomu began to pull All Might into the portal.

"I never said Nomu was going to be the one to kill you. He just has to hold you still in Kurogiri's portal." Shigaraki said, then gave out a dry laugh.

"I don't like leaving things in my portals, but for you and all the parts you'll be leaving. I'm willing to make an exception," Kurogiri said. as the portal began to expand to allow All Might to easily push through.

As All Might got close to the portal, he struggled even harder against Nomu's grip. When he was only an inch away ice suddenly formed around Nomu. Anchoring him in place and stopping All Might only a few centimetres from the portal. All Might looked over to see where the ice was coming from.

"Sorry it took me a moment to get here. Your thugs weren't willing to give much information without some percussion." Shoto Todoroki had arrived on the scene.

"Kurogiri, help Nomu," Shigaraki said. Suddenly an explosion went off right next to his ear, then one threw Kurogiri to the ground.

"Impossible. My body was hidden," Kurogiri said as Bakugo landed next to him, gripping the metal neckpiece.

"In the beginning, I didn't think you had a body, but then why would you be wearing this piece of neck armor?" Bakugo said, lighting off a small explosion against the armor, "You move and you're dead."

Shigaraki dodged a hit attack from Kirishima, "All you annoying NPCs."

"THANK YOU FOR THE RESCUE," All Might said, breaking out of the frozen Nomu, "NOW SURRENDER."

"We were so close, you lied Master. All Might hasn't gotten any weaker. Nomu free Kurogiri., Shigaraki commanded, kicking Kirishima away.

All Might was able to make a comment about Nomu not being able to free itself without injury then he remembered it had hyper regeneration. All Might looked over and saw Nomu racing towards Bakugo. All Might began to move, yet he knew he wouldn't be able to grab Bakugo and get out of the way.

All Might got there first and pushed Bakugou out of the way and took the hit. However, Nomu's attack had been aimed at All Might's wound. All Might could feel blood begin to tickle into his mouth. There was no longer a mere coincidence of Nomu hitting All Might's injury, it knew where it was. The only question now was how did it know?

"You heroes are so predictable. Will always protect those weaker than you," Shigaraki said, staring All Might down.

"YOUNG TODOROKI, YOUNG KIRISHIMA. GET BACK TO THE REST OF YOUR CLASS. LEAVE THE REST TO ME." All Might pushed Nomu away from him. He wanted the students out of the way of the fight, but also All Might could feel his body straining. The attack on his wound was cutting his time down. He could tell he had maybe two last good punches.

Kirishima began to protest, but Todokri grabbed his collar and dragged him away, "All Might wants us out of the way or we'll be a distraction."

"Fine." Kirishima let Todoroki drag him away from the fight.

"SO HOW ABOUT FINISHING OUR FIGHT?" All Might said, shifting his feet to get ready. The motion caused some dust to pick up behind him, adding to the dramatic flare of his word. All Might took a deep breath as he prepared himself for whatever happened next.

"Nomu, kill him," Shigaraki said, pointing at All Might

Like before the two titans ran at each other. However, this time both were much slower and All Might noticed. The wounds given to Nomu previously by Gizon and Ochaco were starting to affect it. It didn't have unlimited stamina, so repetitive use of its quirks was slowing it down. All Might know what he had to do. All Might gritted his teeth and began to punch much harder and faster than his wound should have let him.

"MY STUDENT HAVE HEARD THESE WORDS BEFORE, TODAY SOME HAVE EVEN LEARNED WHAT THEY MEAN. BUT ALLOW ME TO SHOW YOU THEIR TRUE MEANING. GO BEYOND, PLUS ULTRA!" All Might yelled as he deflected a punch, then brought a hard upper jaw upon Nomu. The initial contact did nothing, but with the follow-through, Nomu went flying into the air. He hit the top of the USJ dome, then went through it, "A HERO'S JOB IS PROTECT THOSE AROUND THEM. TO FIGHT WITH ALL THEIR POWER, THEN PUSH PAST THEIR LIMITS."

All Might couldn't move a muscle, as steam began to flow off his body. Luckily it was masked by the dust. He had done more than pushed past his limits. If he tried to move, then his body would deflate and he would be defenceless. All he could do was bluff.

"Then let's see how you deal with this," Shigaraki said, a grin appearing behind his mask.

Suddenly a purple portal opened a few feet away from All Might. He could only watch as Nomu came flying out of the portal. It yelled as it had its fist reared back, ready to throw a punch that would kill All Might. All Might froze, as there was nothing else he could do. If he moved, he would deflate and Nomu would most likely kill him. Even if Nomu missed, then Toshinori's weakened state would be revealed and then he would be killed. Yet if he didn't move then the result would be the same, his death.

"He's not done yet." A voice came from behind All Might. All Might felt a person run into his back, then grab ahold of his shoulder. All Might felt his body begin to deflate, then suddenly it was full of energy. The energy was completely different from One for All, but it mixed with One for All blazing the embers All Might had left. A small smouldering fire was now a large bonfire.

"One more time then. With power behind it." The voice said, it rang in All Might's ear, like ancient church bells. It held untold power, enough to shake the world and cause all to bow before it.

All Might looked down at his fists, a small golden glow was emitting from him.

"AGREED." All Might draw back his fist and met Nomu head-on. His reach was longer, so Nomu got hit first. The power and strength were tenfold of the previous hit. It looked as if Nomu was gone before All Might's knuckles even made contact. One second it was reaching forward to grab All Might, and then next it vanished. No dust trail, no screech from the creature. The only sign to Nomu's exit was a second hole within the USJ roof.

"Impossible," Shigaraki yelled, scratching his neck. The red rash became worse, he even began to draw blood.

All Might heard was a body hit the floor behind him. He looked back and saw Gizon kneeling on the floor. Blood was leaking out of his mouth, and his body was worse for wear. All Might feared Gizon had received the same level of injury he had six years ago.

Gizon held up a thumb and said, "Limits are bullshit."

"So Shigaraki, do you surrender?" All Might asked, flexing his entire body. Now that Gizon wasn't holding onto him, All Might felt just as weak. Luckily this time there was no way Nomu would be returning.

"This is unfair, all your dumb powerups and secondary phases. You cheated," Shigaraki yelled. All Might would have slapped the villain if he could move. He could feel his body struggling to keep its form, whatever Gizon had done or given him was the sole reason he was holding this form. Yet now that power was beginning to fade.

Suddenly a gunshot went off and Shigaraki's shoulder was pierced. Two more shots hit before Kurogiri covered Shigaraki, and then both of them disappeared.

"So that's what One for All looks like." Gizon said, then started laughing. Obviously, his mind was shutting down, a tactile to numb the pain he was feeling. By making it seem like one giant joke, a feeling Gizon regrettably was used to.

"How do you know that name?" All Might asked, quickly turning around and looking down at Gizon. Gizon just looked at All Might and gave a giant smile.

"I'll tell you my secret, if you tell me yours and I believe Ochaco is involved. You two share something and it isn't family ties." Gizon laughed a bit, his eyes starting to glaze over. It was weird, it felt like he could sense the energy of people's quirks, something he couldn't do before. He could sense their quirk's energy and it felt similar, Ochaco just had a little extra on the side.

"All Might," Occaho said, coming through the dust. She was floating and pulling herself along with her good arm. When she was next to Gizon, she cancelled her quirk and let her fall to the ground. Though she barely dropped an inch, the pain from hitting the ground made her mind instantly go white. It took all of her willpower to bring the world back into focus.

"Young Uraraka." All Might said, then deflated, "crap."

Suddenly a cement wall separated the three from the rest of the USJ, "Cemenentos." Toshinori said, happy to have the support of the other UA teachers.

"All Might!" Cementos said in a concerned tone. He hadn't realized Gizon and Ochaco were around. If he had he would have separated the two from All Might

"Don't worry, I trust these two," Toshonori said. He had a small smile on his face, as he looked at Ochaco. She was looking at Gizon with a concerned look, as he still had a massively stupid grin on his face. He looked like a horror villain as his teeth were stained with his blood and blood trails were going down his chin and neck.

"Where the hell did this come from?" Powerloader yelled. Everyone looked over and saw he was picking apart the metal suit that Shigaraki hadn't fully decayed.

"A villain was wearing it," Gizon said, in a chirpy voice. He then laughed as if he thought of a really funny joke. He began to rock back and forth, causing Ochaco's concern for him to grow that much more.

Powerloader had a look of dread on his face as he pulled out his phone and dialed a number, "I need a pair of cleaner robots to the USJ to move some salvage. Tell Midoriya and Hatsume to meet me in Classroom 6-G."

Powerloader looked back down the mangled suit with a look of dread on his face. If a villain had access to build this kind of suit, there was no telling who he shared it with.

And that's chapter 15. Not only does Gizon know about All for One, he knows about One for All. And a bit more is reveal about what he's able to do with his powers. I figured a good way to do that was to have Nomu come back over the cannon launching into the forest. All Might was running on empty so he would need someone to step in and help.

Next week, Izuku and Hatsume learn about the attack on USJ and learn that Hisashi wasn't the only one that had access to the iron man suit designs. Was Hisashi racing against a villain to build a suit, or was Hisashi working with the villain and the villain stole the blueprints.
