Chapter 30

The fight between All Might and All For One continued. Attacks were exchanged, but it was at a much slower pace than anyone watching was anticipating. The two seemed to have a long history that no one knew about, so they spoke a lot between their attacks.

One particular moment stuck out to Killua. All Might angrily said that All For One always took advantage of and controlled people to make them do what he wanted them to do. He had a feeling that he was a part of that, though he was sure the hero was not solely thinking about Killua, if at all. There must have been many other people All Might saw who had fallen into the villain's clutches over the years.

All Might rushed towards his enemy. All For One put out his arm to counter the attack, but All Might grabbed it and pulled it to the side and used a crushing grip to lock it there. With his free hand, he punched the villain in the face so hard the mask broke apart. All Might carried his attack's momentum all the way down and slammed All For One into the ground which cratered it and sent rumbles through the ground below everyone's feet.

The rumbling in the ground was enough to make Gran Torino raise his head after All For One warped him to take a powerful punch from All Might which momentarily knocked him out. "Toshinori, you're at your limit," he observed the steam coming off the other hero's body.

Gon glanced over at Killua and shot a concerned look. "A limit? Can he only use his Quirk for a certain amount of time?" he asked. Killua shrugged because he did not know the answer either. The green haired teen turned back to All Might who was still steaming while All For One, who was still conscious after being punched into the ground, was saying how upset All Might was because of something the villain said.

Gon ran over to the other students who were still watching the events that unfolded. "You guys should leave." Gon did not suggest it. He was ordering them to leave.

Bakugo glared and grit his teeth at Gon, but he looked like he would concede. Midoriya hesitantly wandered his eyes between all of his classmates, from Bakugo to Iida to Kirishima to Kaminari. He nodded very subtly, and Iida followed with a much stronger nod. Midoriya and Iida locked eyes and they ran off, and Bakugo followed them two seconds later.

The ash blond teen turned his head back to Kirishima and Kaminari, noticing they were not following. "Oi, you two coming?"

Kaminari glanced at Kirishima's hardened look. He turned back to Bakugo and replied, "I think we're staying here for a bit. Need to talk with Killua again."

Bakugo huffed with narrowed eyes. He did not trust Killua, and as much as he would not admit it, he would hate to see either of his classmates be injured from this. He had a vague feeling Gon would not let that happen. He still believed Gon was from Killua's world and was incredibly powerful. He nodded and turned around and followed the direction Midoriya and Iida were running in.

"Kaminari! Kirishima! We have reached our goal! We should turn back now!" Iida bellowed from 15 meters away, not wanting them to stay which he got the feeling was what they wanted.

"Yeah, leave it to All Might!" Midoriya shouted too.

Gon stared piercingly at the two Class A boys right in front of him. "You should leave," he repeated in a strong tone. "We don't know how things will be here. I'm here for Killua. Leave him to me."

Heavy footsteps were pounding behind the trio. Iida ran up to them with an angry look on his face. "We are done here!" he berated his classmates. "I told you I will call things off immediately if it gets too dangerous for my liking. We have reached that point. We achieved our goal too. Come with us." He gave Kaminari and Kirishima the same look Gon gave just a few moments ago. It intimidated his classmates as he wanted it too.

Kirishima looked uncomfortable but nodded reluctantly. Kaminari turned to Gon, "We'll leave it to you, Gon. Make sure you get through to him. Remind him of…any…friendship times he had with any of us," he stumbled but made sure he got his points across.

Gon nodded enthusiastically. "Don't worry, I know what you mean! I'm sure you guys made things much more fun for him here. Thanks for that!"

"Be careful," Kirishima added softly. "Let All Might handle this villain."

The Class A students left, and Gon walked over to Killua. Once he got back, a bright flash erupted and smoke blew over everywhere in their surroundings. Through the smoke, Gon and Killua noticed a big shadow get blasted up into the sky. Gon cleared the air filled with smoke around him with a punch at both of his sides. His and Killua's eyes shot up to the sky where they saw All Might about to crash into a helicopter that probably held news reporters who were broadcasting the fight.

Neither of them made even the slightest movement though. Gon wanted to soar into the sky and stop All Might, but he saw Gran Torino coming from behind the strong hero anyways. The old hero caught All Might and safely brought him back down.

"All Might, as much as you hate me, I hate you too," All For One explained while stretching his right arm out in preparation for an attack. "I want you to die. And today will be that day." The villain gathered several powerful Quirks and combined them into a strong attack.

A massive blast of wind roared through the air and headed towards All Might with the intent to kill him in his weakening state. Gon, Killua, All Might, and Gran Torino all noticed a woman trapped under a ton of rubble who had clawed her way out. The old hero in a yellow costume who was flying away through the air changed directions and shot down to rescue her, but the huge blast of wind from All For One did not let him get close. He only hoped his former mentee would be able to hold the attack back. Gon and Killua jumped back far, and the force of the wind only pushed them back even farther.

Another massive explosion of wind and smoke kicked up when the supervillain's attack passed over. All For One stood up perfectly unharmed and lowered his right arm back down to his side. All Might, in his true form, stood at the opposite end of their clearing, the ground beneath him having broken apart so that he was on his own little island. The woman behind him under the rubble was still there, well and alive. All Might had protected her.

"Show the world your pathetic, true form, 'Symbol of Peace'," All For One said in a low and mocking tone since he knew All Might was in his true form and the helicopter in the air would no doubt capture it.

As the thousands, if not millions, of people watching the broadcast that the helicopter above was live streaming understood what it was they were being shown, the hope they all had was slowly fading. Fear and surprise filled the gaps where hope previously resided.

Watching from a big screen away from the area the fighting was taking place in, Midoriya's eyes widened and his own hope was failing too. The thing he and All Might feared for so long finally happened. All Might's true form was revealed. Next to him, Bakugo watched in shock that the hero he so greatly admired for his strength had been turned into this weak-looking skeleton. Iida, Kirishima, and Kaminari shared similar expressions of shock too.

All Might raised his left hand and clenched it into a fist as he said, "Even though my body is weak, I still have the heart of the Symbol of Peace! You cannot take that away from me!"

All For One shrugged and extended his hands slightly to his sides. "Well then, let me tell you this. Did you know that Tomura Shigaraki is the grandson of your master, Nana Shimura?" After a pause where All Might's heart froze and he stared at his nemesis with huge eyes and a gaping mouth due to the unexpectedness of the statement, All For One continued. "I let the two of you meet, and you must have been so proud when you defeated him."

"Liar…" All Might nearly whispered, but he did not believe that his nemesis was lying. All For One would not lie about this.

"Where's your smile now?" All For One asked knowingly and in an excited tone. "This is fun!"

All Might was busy thinking about something and growling at All For One. But then, his right arm sprung into muscle form and began sparking with energy as he looked ready to throw another attack at All For One.

The villain floated up 20 meters into the sky and was ready to counterattack, but he suddenly felt hot flames coming from his right side. He redirected his attack to his side and blew the flames apart.

"What's with that form of yours, All Might?!" Endeavor shouted out at the hero. From the corner of his eyes, he saw Gon and Killua and narrowed his eyes. "Why are they here…" he grumbled to himself.

Behind Endeavor, Edgeshot noticed the teens too. In particular, he stared at his former intern who fought All Might not long ago. "We made it here on time, it seems," he said and decided to ignore the two teenagers far away from him because he felt there were more important things to focus on.

All For One aimed an attack at the two of them, but Edgeshot rose up and cancelled the attack before it even happened. Kamui Woods rushed in and picked up the badly injured Best Jeanist, Mt. Lady, and Gang Orca with his wood Quirk. Behind All Might, Tiger held Ragdoll in one arm and picked up the other woman caught under rubble with his other arm. "This is the least we can do for you, All Might," he told the other hero as Endeavor and Edgeshot continuously attacked All For One. "Defeat this villain!"

In a second, All For One used one strong attack and cleared the area of the heroes who were annoying him. His fight was with All Might. Endeavor and Edgeshot were simply inconveniences. From his spot in the air which he had yet to move from, he turned his head in the direction where Killua was standing next to Gon and pointed where he sensed the silver haired teen. "Kill All Might. If you do this, I can send you back home."

Killua's heart skipped a beat when he heard All For One's…order. Even from this distance, the villain's voice rang out loud and clear to him. To everyone watching on the screens who could not hear because it was only video and not audio, the direction the villain was pointing in meant nothing to them. The broadcasting camera shifted a bit and showed the full view of the area All For One was pointing towards. Now, everyone clearly saw it.

The crowd began murmuring until louder voices voiced their opinion on what was happening. All around Midoriya, Bakugo, Iida, Kirishima, and Kaminari, as well as a different screen broadcast where Todoroki and Yaoyorozu were, people began shouting.

"It's Killua Zoldyck!"

"Gon Freecss too!"

"What are they both doing there?!"

"Isn't this dangerous for them? They're only kids!"

"Zoldyck is probably gonna fight All Might again!"

"They will definitely help the heroes!"

People shouted out numerous things, and it was not even a conversation. The students often heard two contradictory statements being thrown out at simultaneously. They were shouts of each person's opinion on what Gon and Killua were doing there, but the students knew more than any of them.

Midoriya shakily looked over to his classmates who turned back to the screen in fear after spinning their heads all over as they heard a voice from any direction. They figured All For One asked Killua to do something that they could not hear. Given what they knew about Killua, the most likely order the villain would have given is to kill All Might, or at the very least, help All For One in doing something.

All seven students who knew better than the crowds of what was going on hoped Killua made the 'right' decision, as selfish as it was for them.

"Please, Killua…do it for us…" Kaminari muttered while staring up at the screen with huge eyes that begged his silver haired friend who could not hear him anyways.

Killua felt a hand on his shoulder. He stiffly turned his head to the side to see Gon shaking his head. "Don't," Gon warned and pleaded. "All Might is a great hero!"

"But…we can go home," Killua said slowly. That was the only thing on his mind. Going home. Going back to Alluka, or at least to the Zoldyck Estate to get her back from them.

Gon shook his head again. "You don't know if he's telling the truth about that. Please, Killua! I know you want to go home, back to Alluka. I do too! I want to help you with that! But not by killing All Might," he finished in a flat tone.

"What is the matter?" All For One called out and challenged from the distance between them. "You do want to get home, right?" All Might grit his teeth at the conversation that he was not liking. This was his time to attack All For One, when the villain would not expect it. All For One was a danger to society, and also to Killua. If the boy was convinced to fight All Might, the hero was certain he could not win against two powerful opponents at his current strength. He would have to hope for interference, whether it was from Gon or the other heroes or both.

Gon glared at All For One, not that he could see it anyways. He looked back to Killua who was staring at the ground. "Don't listen to All For One," he pleaded again.

"I told myself I wouldn't fight All Might again because it's All For One's fight," Killua explained while still staring at the ground. "But now, I don't know. It's right in front of me. Killing All Might…it could be our way home!" He started walking forward towards All For One, but Gon was not giving up yet.

"How do you know he'll send us back?! He could just keep us here!" Gon shouted behind Killua's back.

His best friend paused for a moment and tilted his down and to his right. "That might be a risk I'm willing to take." He continued taking steps forward.

"No, Killua, don't!" Gon yelled again, but this time his voice sounded more distant.

Killua grimaced and grit his teeth. Gon's right, I don't know if All For One will keep that 'promise'. There's no telling what he'll do. No guarantee he'll follow through with what he's saying right now.

"Isn't this what you made your backup for?" Gon's voice popped up right behind him, and he did not even notice his friend approaching.

Killua spun around, still unsure of it himself. "Yeah, but…" he trailed off, not knowing what he wanted to say.

"But what?" Gon asked indignantly. "Don't ruin this world just for yourself. Think about all the people here, the ones who need All Might and look up to him! All the time you spent with your Class A friends, or however you see them! They must have made things at least a bit better for you here, right?" He continued in a softer tone, "Don't get too lost in trying to get back home. I know it's important, and you have a reason, but you have your backup too! You're too focused on one thing right now, and that's getting home. It reminds me a bit of the Kite stuff way back." He slowly gazed down to the ground with a look of pain and sadness in his eyes, but then he lifted his head back up. "I was only focused on one thing then, and that was revenge. It was the same with Kurapika and his revenge on the Phantom Troupe. It's not good, and I realized that after it all happened. Don't go to that extent." He looked Killua firmly in the eyes, awaiting his decision.

The silver haired teen understood what his friend was saying. Even still, he turned his head back to All For One. His eyes went over to All Might, who desperately wanted to attack All For One right then and there but was holding off from doing so. The villain would likely be prepared anyways.

"Killua, no!" Gon called out again, this time with more desperation clear in his tone. Gon stomped one foot on the ground. "If you fight All Might, then I'll fight you!" It was a bluff. As much as he did not like the idea of killing All Might, or fighting him at all, Gon would not fight his own friend.

Killua's heart froze for a second, and his eyes widened and froze too. Would he fight Gon just to go home? There was no way either of them would go back without the other, regardless of who won.

All For One grinned when he heard Gon say he would fight Killua. Good, that is one of the scenarios I saw. My plans never accounted for two beings from a different world when I first made my plans. These boys interfered in this. I am planning on winning with or without them. If they destroy each other, I can still continue on with my schedule. They are not necessary.

Killua's eyes returned to their normal size, and he expressed a more determined and decided look on his face. He stared up at All For One. "You know, All For One, I never actually wanted to be a villain. But I had to, because you were the only choice for me to get home." The villain's grin faded. He already knew where this was going. He felt that Killua would not listen to him now. He was on his own, unless he could re-convince Killua or perhaps get Gon to join him.

The silver haired teen continued even though he already knew the villain understood the message. "For all these months, I went along with your plans and listened to you. But I never thought I could take action into my own hands. I've always hated it when someone else tries to set out what I should do." His eyes narrowed, and his tone took a darker turn, "You remind me too much of some people I don't like." He was thinking about the Zoldycks and their obsession with making Killua the heir to the assassin business, even though he did not want to. "I don't like your manipulation. All you had to do was send Gon and I back with one or two uses of that Quirk you have. You know we don't want to be here, nor should we be here. Yet instead you want me to listen to your orders like a good boy because you're giving us a favour in the future, so you want us to work for it. All Might told me you may never send me back, and I believe that. If you have someone as strong as me on your side, why would you send me away? You don't have much of a reason to get rid of me."

"Tomura Shigaraki was right when he told me about your little fight with All Might," All For One said while still floating in the air above everyone else. What he just said sounded completely irrelevant to anything Killua said, but the silver haired teen knew better. "He believed you were making a plan with All Might. I agreed with him when he told me what happened."

"I'm surprised Shigaraki could even think that much," Killua said with disinterest. "I don't care what he thought, or what you thought. I'm not relying on you now. You're unreliable."

All For One's mouth curved down into a frown. He did not like Killua's insult towards Shigaraki. The younger villain had been raised by All For One himself. All For One only picked him because he felt Shigaraki had the potential to be his successor when the time came to it, and here Killua was insulting his choice. "Very well then. What will you do now? You believe someone else in this world has the ability to send you back?"

"Of course," the boy responded with a small grin. "Billions of people, billions of Quirks. Surely one of them can help out."

The other students, as well as the general public that was watching this from the big public screens or on their TVs or computers, all waited in relative silence and stared at the silent screens in front of them. Since the person broadcasting from the helicopter kept their camera inside the closed helicopter, there was no sound except for whatever the broadcaster said. Everyone stared at the screens in anxious confusion to see what would happen next. In their minds, anything could happen, and they did not know what. Neither All Might nor All For One had made any move in the past few minutes. Gon and Killua were closer to the main area of the fight, but they had not done anything either.

"Make the right decision," Kaminari muttered under his breath. What he thought the people on the screen were talking about was what was going on. Next to him, Kirishima nodded without peeling his eyes away from the big screen.

All Might was grimacing all throughout. He should not have let this go on for so long. The longer it went, the more chances All For One had of convincing Killua back to his side. He wanted to end this immediately.

He prepared to jump up and launch an attack while he was in the air. All For One felt the familiar usage of One For All, and he turned to All Might and fired a strong attack at the hero the instant All Might left the ground. All Might flew backwards and into a pile of rubble, but the villain knew he was not out yet. Since All For One did not have enough time to prepare, his attack was much weaker than what was needed to kill his enemy.

"All Might!" Gon shouted out in concern and turned his head to where he saw large pieces of debris getting pushed aside which showed All Might was alive and getting himself out. Satisfied, Gon turned back to All For One and gave a cold glare that the villain could not see anyways. Then, he glanced over to Killua who was looking over where All Might landed too. A split second later, the two locked eyes, and they turned to All For One.

"Send us back," Killua demanded in a voice that was warning the villain for what could come. "Now."

All For One grinned, and the two boys saw how sinister it looked whenever the villain smiled. "Of course not," he responded in a dark tone. His presence became more powerful and scary, but the teenagers in front of him were not shaken. "Even if I lose here and go to prison, even if it is Tartarus, I do not think it would be easy for you to find someone with a Quirk that can help you two. When I come out, I believe I could still find you here in this world."

Gon snorted, and then he chuckled. All For One turned his attention to the green haired teen and expected to hear what he found funny. "Sorry, but from what I know, it seems like you'd be in jail for a really long time. We'll definitely be gone by then."

All For One merely grinned, but he did not say anything that confirmed or denied the boy's belief. "Why would you turn against me now, of all times?"

"Your plan is coming close to its end, at least this…part of it, I guess," Killua said, remembering all the times where he spoke with All For One and Shigaraki. Their main goal always seemed to be killing All Might. All For One's previous tasks for Killua were unrelated to All Might. The two were clearly enemies, and they knew each other quite well. "Now that you're here, fighting All Might, with the hope of achieving one of your goals…it's the perfect time. We'd stop you together."

All For One still kept his grin up. He allowed himself to gently float back down so that he was on an even level with the two boys. In the distance, he heard All Might crawl his way out of the pile he was blasted into and trapped inside after moving dozens of pieces of cement and concrete and metal and who knows what else from on top of him. The hero was exhausted, and he had several lines of blood dripping down his face. All For One ignored him for the time being. "Be that as it may, Killua," he said in an authoritative tone like he knew what the future held for the boys. "Even if you, Gon, or All Might could defeat me, you would be eliminating your one guaranteed way of going home." He tilted his head to his right, "Is that worth it for you?"

Killua hesitated in his response. All For One took the silence as hesitation, and he was pleased that he made Killua rethink his decision.

Gon, however, did not hesitate. "Yes, it's worth it!" He turned to his best friend with full confidence in him. "Right Killua? Tell him it's worth it!"

His friend offered a small smile in Gon's direction before facing All For One again. "Gon's right. You thought you had this all figured out, didn't you, All For One?" He hardened his gaze and continued strongly, "But there are some things even you didn't know. I ran away from my life of killing back in my world. It's stupid and meaningless. I don't kill unless I have to. I've become softer as a result, but at least I'm more human." He turned his head back towards All Might who was sitting in the distance, exhausted and weak from the strength he used so far today. "I can see why All Might is a great hero. I've spoken with him one on one." He whipped his head around back to the villain and continued strongly, "I wouldn't kill him. He deserves to live. He was one of the few who understood where I was coming from and why I was helping you. He didn't approve of it, but we came up with that idea of my backup plan. Which, by the way, is now my main plan." That was like a kick in the gut to All For One. At this point, he knew he could not convince Killua. "I don't trust you to help me and Gon. That's fine. We'll go our own way."

Gon was beaming at Killua. He was so impressed his friend was saying all these things. He truly hoped someone out there could help them. He wanted to go home too. There was no doubt in the back of his mind that Aunt Mito would be so worried. He could not even imagine how furious she would be when he got back to Whale Island.

From the corner of his eye, he watched All For One float back up and ready a powerful attack aimed towards them. Gon's eyes widened, but he simultaneously flooded his legs with Nen on instinct to shoot up to where the villain was floating, leaving a small crater behind him where he just stood. He palmed the villain in the chest and stopped his attack.

The shockwave from the impact was powerful enough that even Killua was unbalanced for a moment. Dust from the ground scattered into the air all around him. He watched with his eyes widening as Gon's direct hit pushed All For One away so hard that he crashed into a building and broke through the outer wall.

All Might and the rest of the country, and even people living outside Japan, watched with their jaws dropping as Gon landed softly on his feet after using such a devastatingly fast and powerful attack they did not know he could use. Most of them had seen Killua fight and would not have been surprised if he did that, but everyone was unaware of Gon's full power.

Endeavor, who was slightly injured from one of All For One's earlier attacks, was not as surprised. He knew the speed his former intern possessed. He put the whole story together when All Might revealed to the world that Killua was from a different world back in that news conference before this whole mess began. When he heard that, he knew Gon told him the truth after the encounter with Stain. Both boys were from the same different world.

Gon kept his watch on the hole in the building that All For One crashed through for any sign of movement from the villain. Sure enough, All For One easily levitated out and took to the sky where he did not think Gon or Killua could contest him in a fight.

All For One shook his head from his position in the sky. "Such a shame. You two could have been so useful."

"It's mutual," Killua called out from the ground. "You could've been so useful. But now you're backed into a corner."

The villain's lips curved up into a grin, not that anyone could see it from a distance in the darkness of the night though. "Oh? Am I? We will see about that." He floated a bit higher and gathered some strength enhancing Quirks to launch a powerful attack at the two that he hoped would at least knock them out.

All Might clenched his jaw from where he was trying to stand up. He was exhausted, his bones and muscles weak. The remnants of One For All were leaving him bit by bit. He saw Gon preparing a counterattack. As loud as he could, the Number 1 Hero yelled out, "Do not fight him! He is dangerous, and this is my fight! You kids should leave!"

Both teens heard him, but Killua shrugged it off. Admittedly, it irked him that All Might still treated them like inexperienced children despite knowing how strong they were. He let Gon jump up into the air while he turned around to All Might's direction. He called out, "Don't worry, we'll be fine. Besides, you need to recover a bit. If it wasn't for us, All For One would probably kill you."

A massive gust of wind thundered past him. He forcefully jumped, but the strength of the wind did not let him land where he wanted to. While he was in the air, he watched Gon go flying through the air, far past All Might, and crashing into a destroyed building from a previous attack.

Killua's eyes widened in rage right before he landed on the ground. He shot a deadly glare at All For One, but the villain could not see it, nor could he feel it because of the distance between them. The ground shook and cracked beneath him when Killua instantly bent his knees the moment he landed. He leaped into the air and left a crater below, his right arm flashing with electricity as he prepared to palm the villain.

He never made it. An air shockwave fused with some strength enhancing abilities, as powerful as the air cannons from a punch used by Gon or All Might, blasted into him and sent him flying backwards to the roof of a nearby building. He landed on his back but flipped himself over to his feet.

"Killua Zoldyck and Gon Freecss seem to be fighting the villain?!" the reporter screamed within the helicopter, bursting into the eardrums of everyone watching on the screens.

All For One grinned again and looked directly at All Might. The hero checked his surroundings, but there was nobody around to rescue him or for him to rescue. Gon was blasted far behind him, and Killua was far off to his left. Summoning his strength, he growled and got to his feet as All For One called out his ultimate combination of Quirks to finish him off.

A blast of wind that came from the hero's right knocked him back down to his knees. It was very fast, but All Might could make out a green flash which no doubt belonged to Gon. Off to his left, a bright blue flash in the corner of his eyes caught his attention. It appeared to be electricity, but All For One stretched his entire body out beyond what was humanly capable. The electricity hit him, seemingly harmlessly, and faded within him.

Gon was so shocked he slowed his momentum and made a hard landing on the ground, digging a trench beneath him as his feet dragged to slow him down. He was a bit worse for wear, with a few scratches and bruises here and there, but he was perfectly functional as usual. He looked up to the villain who said, "Is this not great? I happen to have an elastic rubber Quirk that allows me to nullify electricity."

Gon frowned, but just based on the display there, he expected that rubber Quirk to have some glaring weaknesses. It stretched the user's body out very thin, which meant that with enough force or something sharp, the user could be fatally injured.

On the rooftop of a building around 150 meters away, Killua came to a similar hypothesis, though he was unable to see how All For One's elasticity Quirk properly worked like Gon could because Killua was much farther away.

The silver haired teen bent his knees again and took one jump off the already-ruined roof which partially collapsed after his jump. He landed close to Gon and ran over to catch up. They looked at each other for a second, keeping All For One in their peripheral vision. No words, actions, or gestures were exchanged in that second, but both of them knew what the other was thinking.

It was time to take off the training weights.

The green haired teen rocketed into the sky, having his right fist ready to punch. His friend ran on the ground under All For One until he was behind the villain. All For One turned his body counter-clockwise so that his enlarged right arm enhanced with strength Quirks and Hypertrophy was facing the approaching Gon while Killua was beneath him off to his left.

All For One brought his right arm out in front of him before swinging it back out to his right side to have more momentum. His enlarged arm and Gon's Nen-boosted arm collided in a big explosion of wind. Killua jumped up with his right hand in front of him to palm the villain. All For One sensed the other boy coming, so he weakened his attack's power and let Gon overpower him. The old villain was pushed back, but he used his levitation Quirk to quickly slow down and stop moving in the air. Killua did not even bother keeping his arm up anymore since All For One was in a different location in the air now, and he instead lowered it and sailed back down.

Gon was losing height as he fell after knocking All For One away. He punched and kicked with all four limbs to stay up. With two more kicks behind him, he launched toward All For One. The surge of strength from the Nen he felt in his fist empowered him as he flew towards his opponent.

All For One used the elasticity Quirk though because a bolt of electricity shot towards him. Because of the insulative material, the electricity did not harm him, but Gon kicked his left leg in front of him to slow down a bit so he himself did not get shocked for being too close. He kicked behind him again to up the once he felt it was safe. All For One was still in his elastic form and could not properly defend against the powerful punch the green haired teen delivered to his thin, stretched out midsection.

Killua jumped up with a Lightning Palm while Gon allowed himself to fall but land on his feet. All For One launched an Air Cannon at Killua and pushed him back followed by another with his other hand down at Gon who was jumping up again. Gon was blasted into the ground back-first, and Killua landed on his feet and skid back several meters.

Gon flipped to his feet and planted them down so hard that fissures split underneath him right before he shot up into the air much higher than his opponent. He flipped upside down in the air and kicked above him to blast back down and tackle All For One with him. The villain levitated out of Gon's downward path, but Gon swung his right arm and leg out to the side to redirect himself the way his opponent dodged. With two kicks behind him, he was headed towards his opponent once again. He saw All For One's arm become big again though, so Gon kicked his feet below him and arced two meters over the villain's head. Once he was above and slightly behind the villain, All For One turned around, and Gon spun his head back to see what was going on. Seeing a slight opening, the teen spun his whole body around and kicked his left leg out while he did so. The air cannons from the powerful kick unbalanced All For One's aerial movement.

Killua was rising in the air behind All For One. He had his leg ready to kick the villain, but All For One slammed his powered-up arm on Killua's leg and blasted him into the ground where he made a human-sized crater that was a foot deep.

The silver haired teen's entire backside screamed in pain. Even his Nen defense was not enough to keep himself undamaged. "Killua!" he heard Gon call out but could not see his friend anywhere near him.

Killua slowly stood up without any interruptions from All For One. Gon was keeping him busy by flying around through the air and constantly weaving in and out near the villain with small attacks that All For One was forced to defend against.

The silver haired teen took the opportunity to join in too. Gon and Killua blurred around the villain at speeds the people watching from the screens could barely keep track of. Killua had to land on the ground or a nearby building very often because he had never trained to fight in the air like Gon did.

Gon and Killua came from opposite sides of All For One. The villain turned to the side to block Gon's kick with a powerful punch and tried doing the same to Killua with his other arm. The silver haired teen grabbed onto All For One's arm with his right hand and used it to change his momentum very slightly so that he had a clear hit. Killua used his free left hand and drilled an electric punch in All For One's stomach.

The punch smashed their opponent into the ground. He got up like it was nothing though and flew towards Killua in a fury while the silver haired teen allowed himself to fall. Killua jumped over and to the left of the villain the moment he touched land, but All For One immediately turned around and used Hypertrophy to make his arm bigger. He swung it out and slammed Killua near the top of his back. The hit from the villain unbalanced Killua because he was trying to run away. He used Ken on as much of his back as he could, but a second attack never came like he was expecting after being unbalanced.

Gon sprinted past Killua with a blast of wind and leaped into the air with a flying kick. For that reason, All For One had not attacked Killua a second time. He knew the other boy was coming for him, so he combined Air Cannon with strength enhancing Quirks and blasted Gon away before he could reach and be a threat.

Killua watched Gon get sent through a pile of rubble, and then through a few more before finally slowing down in front of a ruined building. His senses alerted him to something dangerous behind him. Without even looking back, Killua bent the top half of his body forward so that All For One's attack had a slightly greater distance to travel to reach his back since it was coming from above while also flooding his legs with Nen. He jumped forward so fast and with such an impact that a few milliseconds late would have left his body flattened in the ground. The impact from Killua's jump forced the villain behind him to skid back because of how much power the boy's jump held.

Killua skid to a stop and turned around. All For One was still close to where Killua was previously standing two seconds ago. Blue electricity flashed around Killua's body, his fluffy silver hair that fell around his head now standing up much spikier than he liked. His body was on autopilot thanks to Whirlwind, and he was going to overwhelm the villain in close range combat.

All For One took to the air, and Killua followed after him as a blue blur. He needed to fight on the ground, so he would force the villain down. All For One aimed an Air Cannon at him, but Killua learned a bit from watching Gon in these last few minutes. His body automatically kicked his left leg out so he dodged to his right. He took control of his body for a brief second to go up higher in the air above All For One before returning back to Whirlwind.

He shot a Thunderbolt at the villain below him. All For One activated his elasticity to stop the electricity from hurting him. Killua shot his body down and drove a fist into All For One's head, and he dragged his opponent down with his punch and his weight.

The two stood up, and both were panting slightly with All For One a bit moreso. Killua's left palm coated itself with extra electricity before pushing forward towards his opponent. All For One blocked the attack with an arm and twitched a bit from the electricity that flowed into him.

At first, Killua did not feel anything, but then the impact of what he thought his palm attack might feel like struck himself. Killua figured All For One must have had some impact reversing Quirk for Killua to be the one who got hurt.

Off to his right, Killua sensed a massive amount of Nen. He shifted his eyes without turning his head to see what was happening right when he heard Gon shout the word "Rock!". He saw his best friend punch his fist out in front of him before an incredible pressure of wind unlike any Killua ever felt before slammed into him and All For One and sent them flying through the air. The silver haired teen managed to stick himself to the wall of a building that was somewhat destroyed, but the wind from the Jajanken: Rock was just so strong the wall he was on caved in with the help of his weight. All For One was blasted even farther in the distance, though whether or not the villain crashed into anything, Killua could not see.

The silver haired teen jumped out of the building he was in and caught up with Gon who was panting after using such a powerful attack that used a lot of Nen. Gon ran forward, and a bit up ahead, All For One took to the sky before Gon was in striking distance. Killua followed behind his friend and shot another Thunderbolt, but this time All For One dodged it.

Gon came right up to All For One with a Nen boosted punch from his right fist. All For One countered with an equally powerful punch, and the force of the wind blew Killua back down to the ground. The green haired teen himself as well as the villain both flew far away but balanced themselves midair.

The two boys barely gave All For One a chance to fully recover before they were bouncing around everywhere between buildings and giant debris pieces that were a hundred meters apart and throwing out sporadic attacks. Each attack sent out so many shockwaves because of how strong they were that All Might could feel it even from how far he was.

Gon was slowing down while Killua was still bouncing around everywhere at a speed upward of 200 km/h. Gon got in his signature squat position once again and charged up his special move. "First comes rock!" The aura in his hand grew brighter to Killua who did not even need to look to see it while everyone else watching thought he looked silly for just squatting there in the middle of a deadly fight. "Rock! Paper! PAPER!" He believed he would get the mix-up of a long-ranged attack on All For One as an invisible force travelled towards the villain, yet he still sensed the power and pressure it carried. All For One dropped down and dodged the Jajanken: Paper Gon used and an attack from Killua at the same time.

The Number 1 Hero finally climbed to his feet, having let this go too far. "What kind of hero would I be…if I let two children…who are not even from this world…fight my fight for me!" he shouted at himself. He yelled out and summoned all his strength, his right arm turning muscular once again. His left eye flashed blue as he boomed in a strong voice, "Killua! Gon! I thank you for your help, but please stand down and let me handle this. You have done enough, though you should have done nothing at all!"

The two friends heard the hero loud and clear and darted their eyes behind them. All Might was standing, and he was ready to finish All For One. They stood down and sprinted far away from All For One so he would not target them anymore since All Might was closer.

Seeing that Gon and Killua were running from the fight and All Might was standing, ready to fight again, everyone watching was screaming for All Might to end the fight. Despite seeing what their hero truly looked like, they supported him like never before, shouting out for All Might to win.

All For One used his Ultimate Quirk Combination to attack All Might which he never had enough time to use against Gon or Killua. All Might met the attack head on with his right arm, but he was being pushed back. The wind slammed into the two boys far away, and they had to actively focus on not skidding back because of how powerful it was.

All Might transferred his power from his right arm into his left. His right arm shattered and went limp like Midoriya's often would. He landed a direct hit to All For One's head and shoved him back.

The villain buffed up his left arm, but All Might's broken right arm somehow recovered itself from its injuries. The hero took a powerful leap closer towards All For One. He was too close now. All For One opponent could not defend anymore.

The punch from All Might's right hand smashed into his enemy's face. "UNITED…STATES OF…SMAAAAASHHH!" He slammed the villain into the ground so hard the ground crumbled below them and created a giant tornado of wind and debris in a display of power unlike any attack anyone had ever seen. Gon and Killua flew away but kept their balance enough to land on the top of a building to admire the sheer power they just witnessed. Above them, the helicopter was wildly losing control because of the huge gusts of wind from the tornado.

When everything finally settled down, All Might was seen standing over the unconscious All For One with his left arm raised above his head. Gon glanced over at Killua with his mouth wide open in shock. "Wow, my Jajanken isn't even close to that strong."

Killua acknowledged what Gon said though he did not have a reply. He stared at All Might's back which was now buffed back into his muscular form with something akin to admiration. Unbeknownst to him, it would be the last time. He continued staring and said, "This was always All Might's fight. We just stepped in to help him when he needed it most."


This chapter was hard to write for some reason. People seemed very excited for this chapter though so I hope the wait paid off and it lived up to your expectations. I had to give All For One something to help versus electricity, so I gave him a rubber-like Quirk. It would be too unfair if he had nothing. My honest opinion is that All Might only won in canon because of plot armour. I guess this is my way of making it more even since Gon and Killua wore All For One down quite a bit before United States of Smash.

Anyways, part of the reason this took so long is because I came up with a new story idea this week which I want to write after this one. I'll give more details once this story ends, but I think I'll hold off on publishing it until I write a significant amount of it. Or I might just write it for my own entertainment. I don't know. I'll have to see.

Thanks for reading, hope you enjoyed!
