Dabi growled as he began to turn up the heat, attempting to burn Shoto into ashes no matter what new move he was using. It looked impressive, but whatever his plan was, it didn't matter. He would fulfill his wish at last, burning up his old man's prized son before turning towards him. He didn't care as he exacerbated his burns, making them crawl up further to his face. All that mattered was burning everything to ashes.

"Shoto!" mocked Dabi, "It doesn't matter what you do. In the end, you who didn't bother training his fire despite given everything, will end up being burned by me!"

Flashfire Fist: Hell Spider

Dabi sent out streams of fire from his fingertips towards Shoto. Ten streams converged all at Shoto, where Dabi intended to not only shred and burn Shoto into pieces, but use the remaining attack to kill all the heroes around them, conveniently blaming it on Endeavor for all those deaths.

Dabi was puzzled when Shoto didn't attempt to summon ice to block, but rather faced the flames head on. Instead, surrounding Shoto's hands were icey blue flames. At first, Dabi thought that Shoto had somehow managed to summon flames just as hot as his, but without any of the burning side effects he had to deal with. That enraged him further that Shoto had managed to attain such flames without doing his best. Then he realized the flames seemed off, unlike his flames that were giving off intense heat, his didn't seem to do so.

Shoto raised both his arms up before swinging them down right towards Dabi's attack.

Flashfire Fist: Coldflame's Flame Blade.

Shoto's attack slammed into the Dabi's attack, the attacks clashing against each other. It was then that Dabi noticed that the heat was starting to drastically drop before Shoto's attack overpowered his own, crashing into his body.

'The attack neutralized the heat of my attack?' blinked Dabi in shock as he was pushed back, noting that Shoto had purposely pushed him further away from the other heroes.

"Still sentimental about the other heroes, Shoto!" shouted Dabi as he quickly fired up his quirk once more, "I don't know what you did, but it doesn't matter! The end result will still be the same!"

"It won't end the way you want!" replied Shoto as the flames around his chest began to glow brighter, "I will stop you!"

Suddenly, the flames went out, much to Shoto's shock.

'Shit, I haven't had enough time to master this state!' thought Shoto before trying to gather the flames within him once again.

"Shoto!" mocked Dabi, "It looks like you haven't fully mastered that move. Big Brother is so disappointed!"

Dabi went on the attack once more, forcing Shoto to abandon his current move to summon a giant ice wall to defend himself. His new move, Phosphor, wasn't perfected yet. He needed time to gather the fire and ice quirks within him.

Katsuki glared at Tomura Shigaraki, who was currently being controlled by All for One. The one who had stabbed his girl, who had to save him in his own moment of weakness. If there was something Katsuki Bakugo absolutely hated, it was being weak and somebody else paying the price for it. Seeing Himiko having to save him at the cost of risking her own life was a double whammy for him. In fact, when he saw All for One drop Himiko's body, he felt his sweat double, pouring from not only his hands, feet, and head, but all over his body.

Katsuki yearned to beat All for One half to death, but he knew his own limitations. As All for One had calmly observed, the explosions originated from the ends of his limbs to attack and move. Even though he was fast and could instinctively know how to position his body in the air, taking those away was enough to render him powerless.

'What can I do?' thought Katsuki to himself as he glared at All for One, noting everything he did. How he attacked, how he defended, how he responded to each individual. Everything began to slow down in Katsuki's eyes as he began to be able to see each one of All for One's attacks, and even predict what he would do.

'But what use is that if I can't react fast enough?' pondered a frustrated Katsuki as he wiped off some sweat from his forehead onto his arms before looking down at his arms.

Suddenly, a mental explosion went off inside Katsuki's mind. His sweat was the key component to creating explosions. He always used his hands to control it as it was the easiest way to direct them. Using his feet to help control and attack came after Izuku's suggestion. But what if that could be expanded upon his whole body? Sweat came from the whole body, not just his limbs. And right now, he was covered in his own sweat.

Taking a swig of a specialized sports drink to replenish as much sweat as he could, Katsuki slowly walked towards All for One, his eyes focused solely on him.

"Hey kid, it's too dangerous for you, get out of here!" said one Pro hero as she tried to reach out to stop him.

One second, Katsuki was there, walking slowly if not menacingly, and in the next second, he suddenly disappeared from her view, leaving a trail of explosions.

All for One was annoyed. Seeing a shadow of Kudo had definitely made him act rash, but in the end, it didn't matter. He had upweeded a traitor, and while all these heroes were certainly making it annoying to escape, it wasn't without any benefit. There were a few quirks that he was certainly interested in taking before he made his grand escape. He had already taken two of said quirks, and was looking for a chance to escape, steal Star and Stripe quirk, and/or kill Toshinori, when it happened.

At one moment, All for One sneered as he saw Katsuki glaring at him and deemed him as a barking puppy, unable to do anything to him. The next moment, he heard explosions as well as a gloved hand already in front of his face. Sparks came out before the explosion consumed his whole body.

All for One growled as Super Regeneration kicked in, swiping his hand at Katsuki in annoyance. The fool was stupid enough to come so close that it would be easy to kill him with one swipe. The fact that he reminded him of Kudo, the one who was responsible for starting the chain of events that would lead to One for All being passed around, would only increase his satisfaction of killing Katsuki.

Another chain of explosions could be heard, but it wasn't directed at All for One. Instead, Katsuki suddenly disappeared from his view, only to suddenly appear from behind to let out another giant explosion.

"What!?" coughed out All for One in shock, "How did he suddenly get so fast!?"

Katsuki grinned as he let out a chain of explosions to boost him away. Despite looking like he was ragdolling in the air, Katsuki had complete control of his airtime by instinct alone. Landing away from All for One, Katsuki took this chance to get his breath while picking up a piece of jagged rock. Letting it soak in his sweat, he threw it up into the air before launching himself towards him once more via explosions, changing his position to keep himself moving.

"Annoying brat," growled All for One as he managed to track down Katsuki's position despite him flying around, "Die and never appear before me again!"

All for One shot out black tendrils towards Katsuki, intercepting his path towards him.

'He can't dodge this in time at his speed and reaction,' thought All for One.

Suddenly, explosions appeared in front of Katsuki, not to deter the tendrils, but to kill Katuski's momentum forward. The sudden halt allowed Katsuki to maneuver his body to dodge the tendrils before using explosions to shoot himself forward at an angle, dodging All for One's attacks.

'That sudden shift in momentum! It's like-' thought All for One only for a jagged rock to suddenly rocket towards his temple.

All for One dodged it, cursing under his breath as he was reminded of Kudo once more, only for Katsuki to interrupt his thought with another explosion to the face.

'How is he still able to move despite all the G forces his body is experiencing!?' thought All for One.

Truthfully, though Katsuki was tough and built up a resistance to a certain degree, the amount he was experiencing would've overwhelmed him if it wasn't for a few things. His natural stubbornness, training, and the fact that Star and Stripe applied New Order onto Katsuki to become even more resilient.

"C'mon!" roared Katsuki as he sent off a chain of explosions, knocking All for One to the ground, "I'm not finished with you yet!"

"Kudo!" growled All for One in frustration, "You always ruined everything!"

"You getting memory loss?" taunted Katsuki, "You better remember this name as the one who beat the shit out of you. I'm Katsuki Bakugo, and my hero name is: Great Explosion Murder God Dynamight!"

Those who heard his name slightly winced at his rather atrocious and edgy hero name.

"Enough of this!" roared All for One in rage as he summoned a shockwave quirk that originated from his whole body, sending a destructive pulse out. Both heroes and Nomus were caught in the shockwave, tumbling away while bleeding. The Nomus were able to quickly recover, being mindless minions they were while the heroes took longer to recover.

Still, this brought him valuable time to escape. He knew he was running out of time to control Shigaraki's body despite all the upgrades the doctor had put into it. Suddenly, an iron wall blocked his path.

"Don't think it'll be that easy to escape!" grinned Toshinori from behind the wall, "I've fought you more than enough time to know your methodology!"

All for One growled in annoyance as he sent a concentrated blast at Toshinori, who's shield blocked it, but was shattered into pieces.

Suddenly, a bullet tore through the air, rushing towards All for One from a blind spot, slamming into neck. At first glance, it seemed to have been a successful hit, only for All for One to laugh.

"You thought I wouldn't be aware of your position!?" mocked All for One as it was revealed that the bullet hadn't actually hit skin. Instead, All for One had used another quirk that allowed him to morph his skin into a hole that the bullet was caught inside.

"I knew that you heroes had two of the quirk erasing bullets, and knew you couldn't resist using it. Now it's mine to use?" stated All for One before noticing something was off with the bullet. The bullet syringe was wrapped up in Kaina's hair, as expected, but when pulling off the said hair, the syringe weight seemed too light. As if the capsule was empty. Quickly pulling up another quirk, he inspected the insides of the syringe bullet only to find out it was empty.

"A blank?" blinked All for One, "But where is the real one!?"

All for One was already on guard for another shot, but it never came. Nor was he the real target.

It had already been concluded that the quirk erasing bullet might not work on Shigaraki or All for One due to the amount of quirks inside their bodies and the fact their bodies had been modified by Garaki. Rather than risk a shot that might not work, instead they would aim for a threat that they knew could be neutralized.

"C'mon Shoto, my little brother! Show me what you can do!" laughed Dabi as he punched Shoto in the face, having mounted onto his waist.

Shoto grunted as he felt the heat infused punches burning his cheeks, having failed to activate Phosphor in time. Suddenly, a body tackled Dabi, freeing Shoto from his position. Shoto got up, immediately using this time to invoke Phosphor once more.

Shoto glanced over to see who had saved him, only to blink in surprise when he saw that his father had been the one to tackle Dabi away despite all his injuries.

"I won't let you!" grunted Endeavor, feeling the flames burning on his skin.

He didn't care as the flames cauterized his wounds, and the pain allowed him to remain conscious. Not only that, but he had a responsibility as a father to not only protect Shoto, but to ensure Dabi wouldn't hurt anybody else anymore.

"What's wrong, dad!?" mocked Dabi as he turned up the heat even further, "It's not too hot for the number one hero now is it?"

Endeavor didn't reply, but rather held Dabi even tighter.

"Shoto! Do whatever you have planned while I have him held in place!" roared Endeavor.

"Oh my, sacrificing your life to protect your youngest child? Seems like you have already abandoned your eldest just like before!" cackled Dabi.

"No. Not this time," said Endeavor, "Once this is all over, then I'll be with you every step of the way to repent what you've…. no, what we've done."

Dabi seemed shocked at this before growing angrier, his flames bursting out even further as he threatened to burn everything to ashes.

Shoto ignored everything as he focused on controlling his quirk, activating Phosphor once more. With a giant yell, Shoto ran forward right into the flames, the flames once more covering his hands.

Great Glacier Aegir

Immediately, the flames were snuffed out as ice filled the area. Before they could say anything though, a shockwave crashed into them, causing them all to stumble.

Dabi, though shocked that all his flames had been neutralized, had already been planning something within his mind. He was the older brother, the one with flames so hot that they overpowered Endeavor's own flame, much less his little brother. If his talentless and lazy little brother could do it, why couldn't he? So he was already attempting to mimic Shoto's Phosphor state, and could feel something happening within his body. He had his dear birth mother's genes that made him resistant to freezing temperature, that meant he had to have some form of ice.

"Anything you can do, I can do better!" laughed Dabi as flames began to kick up once more while Endeavor and Shoto were trying to recover from the shockwave created by All for One.

Suddenly, an arrow slammed into his flank, causing him to stumble.

"The hell?" questioned Dabi as he yanked out the arrow, "You think this can stop me!?"

With a roar, Dabi tightened his grip on the arrow, imagining it burning into flames…. before reality set in as Dabi stared at the currently unburnt arrow.

"What? Why can't I burn this?... Why can't I feel my fire!" shouted Dabi, his eyes widening before noticing just what exactly was on the tip of the arrow.

A familiar red capsule with a syringe on the tip of the arrow, one that had released its contents into Dabi. The capsule Toshinori had gotten from Nezu and had given it to Lady Nagant and Beros before he drove his car to crash into Shigaraki.

Dabi had been the next target when he had revealed himself, and Beros had taken the shot while Kaina distracted All for One with her shots.

Shoto immediately encased Dabi in ice, leaving only his head to move and breathe freely.

"Just chill out in there for me brother until we can settle all of this," breathed out Shoto before turning his attention towards All for One. There was one obstacle left now.

All for One felt his annoyance grow into rage as he saw another potential minion fade away. Not to mention he had lost in a way that he couldn't take the quirk after losing, as it was now gone. Deciding on his next target, he mixed in a batch of quirks into the next attack before firing it directly at Shoto. A deadly laser beam went straight for Shoto before he could even react.

"No!" shouted Endeavor as he let out an impromptu Prominence Blast to block the attack.

Several other heroes were also firing their attacks to block the laser beam, only for it to fail. Even Star and Stripe, utilizing the drones that David Shield was controlling, threw a concentrated laser spear at the laser beam, only for it to do nothing.

Just as the laser was about to hit Shoto, a body slammed into him, shoving Shoto away from the laser. However, the laser blasted right into the said body, leaving the hero who saved Shoto no time to even put his arms up in vain defense.

"No!" shouted Shoto, as the only glimpse before the laser beam overtook the body was someone with blonde hair with a cowlick hairstyle. But the face seemed familiar though.

All for One merely scoffed as he had eliminated one hero while clearing out a path for him to escape. Ordering the Nomu to him, he had them carry his body out towards the cleared path. He needed time to recoup, but with the hidden caches and loyal minions hidden in society, he had all the time to truly conquer Japan, and then the world.

All for One's eyes caught a hero with long blue hair charging up an attack before firing a concentrated wave of energy towards him. Scoffing at the attempt, he had a Nomu jump up to block the attack when a body suddenly appeared right before the Nomu, his right arm raised high up into the air. What shocked All for One was that the body that had appeared was the one he was sure he had obliterated into dust with his attack.

The wave of energy wrapped around the raised arm while the hero rushed forward, phasing through the Nomus while keeping the wave of energy wrapped around his arm and avoiding any obstacle until he was right in front of Shigaraki.

"POOWEERR!" roared Mirio as he slammed a punch right into All for One's face, combined with Neijire's quirk at 100%, sending the man tumbling away.

The body was sent tumbling as All for One quickly tried to recover, knowing his time in Shigaraki's body was growing even shorter.

"This body may not be able to handle this stress, but at this point, there's no choice," grumbled All for One in anger, slightly worried about losing his vessel.

All for One began to summon every quirk he had within the body to accomplish one goal. Massacring all the annoying gnats in his way.

Suddenly, instincts began to warn him something was coming. Something familiar that he had always wanted. Looking up towards the direction of where his senses were telling him the danger was coming was Katsuki Bakugo in the air. However, the danger wasn't him.

Katsuki was holding a black tendril, one he recognized from a hero he had killed long ago. The quirk used by the fifth wield of One for All.

Katsuki grinned as he began to spin, reeling the tendril in while using explosions to accelerate his spin.

"No!" roared All for One as he realized just who was coming.

'He shouldn't be here yet! Has that much time passed already!?' thought All for One to himself, 'Perhaps this time I can use Tomura's hatred to take One for All this time?... No, especially with that devil inside the boy. My only choice…. is to eliminate the boy as he arrives!'

Focusing his quirks all into one target, All for one aimed his hand towards Katsuki while the Nomus surrounded him to defend him from any other attack.

Katsuki didn't give a damn about his headache as he spun even faster than he had ever done. When he saw the black tendril reaching out, he immediately shot himself towards it, knowing just whom it belonged to. He had managed to block the shockwave with his own explosion, giving him time to get into position.

Howitzer Explode-a-Pult: Cluster

Katsuki spun even faster than ever as he reeled the tendril towards his location.

"Get over here and finish this, Deku!" roared Katsuki as the tendril began to wrap around his body while it was being retracted at the same time.

Izuku had been flying towards Jaku City as fast as he could after dealing with Gigantomachia when Cathleen's jets flew past him. After dropping off Star and Stripe, she had ordered them to circle back to pick up Izuku as fast as possible. Forming a line, they allowed Izuku to slingshot forward towards Jaku city faster than one could imagine. All the while, he was having a mental conversation with the predecessors of One for All.

Within mindscape

"Are you sure you want to do this?" asked Kudo, the second wielder of One for All, from his seat, "I think it's a stupid idea."

"Can't help but agree," nodded Bruce, "It's a risky and naive idea, to save Shimura Tenko. Who knows what that bastard did to manipulate everything."

Hikage remained silent, choosing not to voice his opinions. Having been a hermit for most of his life, he didn't exactly have the best social skills or interactions, similar to Yoichi.

"There has to be something we can do," argued Nana, "We know All for One targeted my family for the sole purpose to hurt me and Toshinori mentally. I know it's a naive high risk low return plan, but in the end, it's my fault that this happened. If there's a chance to make it right, I want to take it."

"Yea, but it's the ninth user's life we're talking about," hummed Daigo, "I don't want to risk the kid's life on a maybe."

"Admittedly, Nana's generation and beyond have been more passionate and more successful than we were, even if One for All grew stronger in the later years," stated En, "If there's a chance we can steal a piece back from All for One, this would be our only real chance."

While the users argued for a bit when Yoichi clapped his hands, getting everyone's attention.

"In the end, we should ask the ninth user what he wants to do," said Yoichi, "It's his decision, something that we all must respect. Izuku Midoriya, are you prepared to follow through with what you've decided? It's not too late to back out, and we all understand if you do. There is no shame in retreat if the task proves to be impossible. We all know that it's a very low chance of success."

Izuku nodded, "I know, but even if the possibility isn't 0, then I'll take it. That's what heroes do after all. Defy the odds and meddle in other people's business when you don't need it!"

While Kudo and Bruce sighed, they nodded their heads in agreement.

"Excellent," said Yoichi, "And I believe that I might be able to help with that. I've been thinking about what happened back when my brother tried to steal back this quirk. He temporarily created a bridge between us, and we used that bridge to cross over to his side."

"Where we kicked his ass!" laughed Daigo, causing the others to give a small grin of satisfaction.

"Indeed we did. But what I'm more focused on is the bridge. I never knew how exactly my brother's quirk worked when he stole a quirk or transferred it to another person. That bridge, however, showed me how it worked. And if he can do it, then why can't I, who's original quirk was Quirk Bestowal, make a bridge as well," theorized Yoichi.

Immediately, all the other users began clammering about how insane that idea was and other risks before Yoichi clapped his hands together, creating a loud sound to silence them.

"Why?" asked Kudo, asking the question they all had, "In order to do that, that means potentially transferring One for All to Shimura Tenko, the one that All for One has always wanted. You risk One for All being transferred to him just to create this hypothetical bridge that might not work, just to save someone that might not want to be saved?"

"I have confidence it will work," declared Yoichi, "I've been experimenting for a bit. The transfer worked without DNA back at Nabu island. That, and I have you guys as well as the devil to pull me back if it goes south."

The others grumbled while the devil gave a grunt in reply before Yoichi turned to Izuku.

"In the end, it's your choice. We'll respect whatever you choose," said Yoichi, "You are the current wielder of One for All, and ultimately, you are the leader and the one to choose your path."

Izuku took a deep breath before opening his eyes, his path set. He had never once thought about straying from it, and he wasn't going to do so now. He made up his mind already. He was going to defeat a villain while saving the ones in need, even from themselves.

Izuku had been slingshotted from his current position towards Jaku city at frightening speed, thanks to the jets carrying him forward. After the last jet, Izuku fired Black Whip towards the city, hoping someone would notice and pull him forward. Already the jet pilots had told Star and Stripe that Izuku was coming with the approximate time window.

Star and Strip had gotten the message, and was already looking towards where Izuku was going to appear while dealing with an annoying Nomu that had a form of Super Regeneration. Upon seeing the black tendril belonging to Black Whip, she had been ready to either jump towards it or call out for someone to do so when Katsuki beat her to it, already grabbing the black tendril. He already recognized just what and who it was. Quickly positioning himself, Katsuki began to spin in the air, reeling their trump card forward.

People looked up into the air when they heard and saw the explosions before realizing that Katsuki was reeling something in.

It was too fast for them to keep track. In one moment, there was a black tendril that Katsuki was reeling in. The next moment, Izuku was already zooming past them all to where Katsuki was.

"Go!" roared Katsuki as he threw Izuku towards All for One, using the last of his sweat to create a bigger detonation to accelerate Izuku while pushing himself out of the way.

"DIE!" shouted All for One as he fired not only Rivet Stabs, but almost every other offensive quirk he had, along with support quirks to empower it.

'He's going too fast, he can't react in time or even block!' grinned All for One.

Transmission Low

Izuku's speed suddenly slowed dramatically, ignoring the laws of inertia completely with Gear Shift. This allowed him time to dodge all the attacks, utilizing Danger Sense and Observation Haki to predict All for One's attack. Izuku weaved and dodged through all the attacks before using Gear Shift once more.

Second Gear

Izuku suddenly gained speed once more, as if the inertia that had been ignored had regained its control of Izuku, leaving All for One unable to react to the uppercut to the stomach.

Izuku stomped his feet onto the ground hard, causing his blood to pump even faster within his body, turning his skin pink as One for All flowed throughout his body.

Third Gear

Top Gear

Two more punches slammed into All for One's stomach, launching him into the skies. It was only after being launched did the sound of Izuku's attack ring through the air, as if Izuku had broken the sound barrier with his attacks.

Not even giving him a chance, Izuku sent out Black Whip, grabbing All for One before yanking him back to him. Izuku's other fist, utilizing Fa Jin and Armament Haki, was pulled back as a black obsidian sheen could be seen covering his left fist.

All for One tried to stop Izuku by covering his whole body with electricity, but with Izuku's unique body composition, it had no effect on him. Realizing that was a futile attempt, All for One began to use a quirk that he had implemented but never used due to how difficult it was to use.

The quirk made him turn into a gaseous state. However, returning to a solid state took time and effort, even with all his quirks. Luckily, it was easier to turn solid if it was cold, and there was an ice prison that Shoto had made to entrap Dabi.

Then he noticed the obsidian sheen on Izuku's arm, reminding him vividly of when All Might had punched him with the same color on his arm.

'NO!' thought All for One, but it was too late.

Izuku's punch bypassed his attempted escape and slammed into solid flesh. What made it more painful for All for One is he could somehow feel the punch hitting deep into his soul, weakening his control over Shigaraki.

'What is this attack? How does it even affect the spirit!?' though All for One as he lost control of his arms for a second.

Shigaraki woke up in pain after being punched, and immediately reacted by utilizing his own quirk, grabbing Izuku's Haki covered hand in response.

'Yes, this works!' thought All for One, 'Even if can hit me in any state, he shouldn't have the power to resist Tomura's Decay!'

"That hurts," growled Shigaraki as he tightened his grip on Izuku's hand, "I hate people who hurt me!"

Shigaraki activated Decay, causing everyone who was witnessing the situation to gasp, expecting Izuku to start to decay like the ground, the building, and heroes who had been caught in his decay. Only to grow confused as nothing happened.

"What!?" shouted Shigaraki and All for One. They felt the quirk activate, and could feel Decay attempting to spread, but it couldn't for some reason. They felt something fighting back, if not overwhelming the Decay, as if overflowing will stop it.

"What is this/What type of hack mod are you using!?" demanded the duo.

"Merely a manifestation of my will made physical," said Izuku as he cocked his right hand back, stretching it out while winding it for a screwdriver punch. With a roar, Izuku stepped forward.

Connecticut Smash

With not only Armament Haki, One for All, and Fa Jin infused to the punch, Gear Shift accelerated Izuku's attack right into All for One's mouth. What was unseen on the fist was a strand of Izuku's hair that when his attack slammed into him, the hair happened to be deposited right into Shigaraki's throat to swallow.

'Time for the final real battle,' thought Izuku in his mind as everything turned white.

Mindscape

Izuku blinked to find himself in a familiar setting once more. A barren land full of rocks with purple and red sky that swirled all around. The vestige world of One for All and All for One. Looking across, Izuku saw Shigaraki Tomura, or rather his true name, Shimura Tenko, struggling as All for One was attached to him like a parasite.

"Come now Tomura," said All for One in a rather patronizing tone, "I had to intervene to lend you my strength. Otherwise you would've been captured."

"All for One!" shouted Izuku, causing All for One to twitch and blink in surprise at Izuku's sudden appearance.

"What? How?" questioned All for One, "You can't be here! I haven't used my quirk to steal your quirk yet!"

"I did," said Yoichi as he walked up into view from behind Izuku, "Thanks to having a first person view of how you used your quirk within the mindscape, it became easier to create a bridge like you did. After all, you can take away and give quirks, then why can't I, who's original quirk was to Quirk Bestowal, do the same? I've shared One for All's power up with other people since we reached singularity with this."

All for One blinked in shock at this statement before grinning.

"So you foolishly decided to give One for All to Tomura in hopes of creating a bridge to defeat me!" laughed All for One, "How foolish. Just because you escaped me once due to some freak accident doesn't mean it will happen again. When I tried to take One for All with my original body, I only had a copy of All for One in that body. Meaning that I only had a fraction of my power in my body compared to this one, that has the real and original version of my quirk, All for One. Now, together with my successor's hatred, we will fully take One for All, my little brother!"

All for One paused as he felt Shigaraki's hatred crawl up on him for a second before glancing down.

"That's right, you hate me too. That's fine, all the more fitting for the Symbol of Fear," chuckled All for One, "It will affect the rule that One for All can't be taken, especially since they were so foolish to initiate the process!"

The ground and sky began to erode as Shigaraki's rage began to affect the world they were at, rushing towards Izuku's side.

"Don't think it'll be that easy," declared Yoichi as he raised his hands up, "Afterall, we're not alone here."

Instantly, five more figures appeared behind Izuku, each one of them raising their hands up towards All for One. The erosion immediately stopped upon their own will.

"So the rest of you are also awake," hummed All for One, "I should've expected that back when you all tried to hurt me during that time. But no matter, you've made a fatal mistake showing yourselves. Especially you, Nana Shimura! Look Tomura, the dead person who happens to be your grandmother is in front of you. Don't you have something to say to her, for the one being responsible for everything you've gone through?"

All for One began explaining that every time he appropriated a quirk, how he would see echoes or vestiges of the original owners of said quirks. Of course, they all cursed at him, but he was immune and deaf to their voices. It was this theory that allowed One for All to also carry the vestiges of the past users of said quirk along to each new user, as One for All took in the quirks of the said wielder.

"Tenko," said Nana tenderly, looking at her grandson, who was currently being parasitized by All for One.

"Nana Shimura," grunted Shigaraki as he glared especially at Nana, his mind flashing back to a memory of a photo that his 'father' had hidden in his study. It had been a photo of him as a child along with Nana, revealing their connection. The one that his father had cruelly beaten him for peeking at the photo, telling him how he despised heroes, coming up with the line that heroes were people who hurt their own families just to serve other people.

"It doesn't matter how we ended in this situation grandma," scoffed Shigaraki, "You can be rest assured you'll receive my hatred as well!"

Once again, Shigaraki tried to force his hatred through, only for the others to block it.

"I know," said Nana sadly before looking straight at Shigaraki, "And I deserve every bit of hatred that you have for me. For causing this mess in the first place. But in return for taking all your hatred, I'll save you."

All for One howled in laughter at her words before asking, "And how do you intend to do that? You who not only failed to defeat me, but even failed your own family!"

"She won't be alone," said Izuku as he took a step forward, "We'll be here every step of the way to stop you All for One and save Tomura from you."

"I don't need your help!" lashed out Shigaraki as parts of the world began to erode once more, "You heroes are always busy meddling in business that you have no right to be a part of!"

Izuku merely smiled, "Then why does it look like you're asking for help?"

Izuku kept walking even further in, clearly stepping into All for One's domain, with Nana following Izuku every step of the way.

Suddenly, they were surrounded by shadowy hands, all trying to grab onto Izuku. Some were desperately trying to escape from All for One's grasp, others were trying to drag Izuku down to suffer with them, and some were loyally obeying All for One's orders, while the rest were chains from All for One.

'Now, drown! Drown into the abyss that you so foolishly chose to jump in!' thought All for One.

Just as the hands and chains were about to touch Izuku, as the wave of eroding energy traveled towards Izuku, Izuku merely took a deep breath through his nose before slowly looking up, adjusting his straw hat that had somehow come with him in the vestige world. The pupils in his eyes suddenly constricted as Izuku let out a blast of Conqueror's Haki from his body. The invisible wave of energy passed through everything, causing whatever it hit to freeze in place.

"What!?" shouted All for One and Shigaraki in confusion and, for once in All for One's life, fear for his life.

Izuku didn't give All for One the chance to recover as he rushed forward, his right arm already cocking back and twisting for his go to punch. His fist was already covered in Armament Haki as it began unwinding, with One for All coursing through him.

Nebraska Smash

The punch slammed into All for One, but Izuku wasn't done. Taking a step forward, he forced the punch downwards, slamming All for One, and by extension Shigaraki as All for One was still attached to him, into the ground. Black lightning with a red outline flashed all over the place, with the origin coming from Izuku's punch, conqueror Haki spilling all over the place.

The ground collapsed beneath them sending the trio down the abyss, with Nana quickly diving in to give chase.

"Should we also dive in?" asked Banjo.

Kudo responded by jumping into the abyss to give chase, followed by Bruce.

"Does that answer your question?" chuckled Hikage, "I'm going to go. Though we're going into unknown territory, my Danger Sense may still be of use somehow. You can stay if you want."

"Hell no, I'm going," shot back Banjo, "You can't stop me."

"Yoichi and I will stay behind to maintain the bridge," said En, but Yoichi shook his head.

"This is my fight that has gone far too long, and now it's time to end this," said Yoichi, "You maintain the bridge. My presence will agitate my brother and make him focus on me, giving him tunnel vision. That's a chance we can use."

"Alright, let's stop wasting time and go!" said Banjo as he shot out Black Whip, grabbing Yoichi before jumping down, with Hikage following behind.

En sighed as he sat down, maintaining the connection that Yoichi had left behind. As much as he wanted to go, he knew his Smokescreen would be of no use in this fight. But he could use it to help signal a way back for them.

"Good luck," said En out loud to the world.

Falling. Diving. Descending. Plunging. Sinking. Those were the words Izuku could only think of as he fell further and further into darkness. But he looked onwards, unafraid of the abyss. Behind him, he could feel Nana just right behind him, with the other users further back behind him, chasing to catch up.

Soon, Izuku saw a glimpse of light before turning himself towards it, steering to the light. The light got brighter and brighter as he closed in until he had to shield his eyes.

Upon regaining his vision, Izuku noticed he was now standing in front of a house with the name Magi/Shimura on the nameplate.

"This… this is most likely his origin," whispered Nana as she landed next to Izuku, "Where everything began. The others are trying to catch up, but I don't know how long it'll take for them to arrive since we're here. Time might move differently. Not only that, but we seem to have a physical form here."

Izuku nodded as he stepped forward. They couldn't waste any time just waiting for the others, especially at this critical moment. Walking forward, they met no resistance, most likely because Shigaraki had been knocked into a daze when Izuku had punched All for One from earlier. A shadowy figure had appeared, but Izuku backhanded the figure out of the way.

"You ready?" asked Izuku.

Nana nodded, ready to see what caused her grandson to stray so far, to becoming All for One's pawn.

Opening the door, the first thing they saw was a photo of Nana herself hugging her child, Kotaro, before she had to give him up for adoption to prevent All for One from using him against her.

'This photo… He must have kept it as a keepsake,' thought Nana.

The duo could hear an echo of another child's voice, stating that the hero in the photo was their grandmother, and that they would become heroes together without their father knowing.

However, the next scene chilled their bones, especially Nana.

Upon entering, they saw Kotaro, now fully grown, slapping a shadowy childlike figure that was clearly Shigaraki as a child, without any remorse nor restraint.

"That wasn't your grandmother in that photo," said Kotaro coldly, "That was a monster who abandoned her child just to be a hero!"

Nana could feel her heart shattering upon hearing such words from her son, her vision becoming hazy from her tears.

"Heroes are just people who are willing to hurt their own families only to help complete strangers!" shouted Kotaro.

Nana realized that Kotaro hadn't kept the photo as a keepsake of their treasured time together, but as a reminder of how much he hated her for leaving him. She had left him in foster care to protect him, but it had been in vain as All for One had still managed to find a blood connection to her. All it had done was foster resentment towards her that grew and apparently spread to her grandson. She was the one responsible for Tomura's origin, no matter her intentions.

When she saw the image of her son raising his hand once more to slap her grandson, she knew she couldn't just watch anymore.

Nana didn't care that it was the past, she needed to do something. She rushed forward, running straight into an invisible barrier, rejecting her. She didn't care as she pounded at the barrier as hard as she could.

"No, no, NO!" screamed Nana, "Let me IN! I won't let this go on any longer!"

With a frenzied shout, she raised her right arm to punch the barrier with all her strength. Her right fist suddenly gained a black sheen as Izuku touched her back. Though Izuku allowed her to be able to use Armament Haki, it was Nana's own willpower that was smashing into the barrier.

The barrier shattered into pieces, allowing Nana to rush forward before getting in between Kotora and Shigaraki. The slap hit Nana, but she stood firm.

"Who the hell are you! Get out!" shouted Kotaro, raising his arm once more.

"No," said Nana definitely as she raised her head, "I won't let you hurt him anymore. Yet I am responsible for all this. So release all your anger on me, the one who deserves it!"

Izuku walked up to Shigaraki, who's shadowy figure began to fade away as they could see Shigaraki Tomura, or rather Shimura Tenko's childhood form.

Suddenly, the scene changed, showcasing when Tenko first activated Decay, only to kill his family dog. In a panic, he tried to grab his sister for help, not knowing what would happen until Izuku suddenly appeared, intercepting his hands with his own.

Izuku questioned why he was in his kid form, but chose not to question it as he held on tightly to prevent him from grabbing anything else, using armament Haki to protect himself.

"It's alright now. You don't have to be scared anymore," said Izuku as he halted Tenko.

"... Go away!" shouted Tenko, "You heroes are always pretending to be helping others! I didn't ask for your help!"

"You didn't," acknowledged Izuku, nodding his head, "But you looked like you were asking for help from your eyes. And I can't ignore that even if you're a villain and I'm a hero."

"... No! I chose this!" cried Tenko, "I destroyed my house and killed my family under my own volition! Otherwise… otherwise.. why else would I have these hands…. this quirk. Who could explain why I was born this way!? To be alone!?"

Izuku felt Tenko's hatred washing over him, threatening to decay his arms, but Izuku stood firm. He was just as stubborn as Tenko was when it came to helping others, his willpower tempered from everything he had experienced in life.

"It's a difficult question to answer, but I can tell you this," said Izuku slowly, "Nobody was born to be alone. There will be someone there to hold out their hand to help you. That's why I'm here now. To help you and offer my hand."

Tenko felt his willpower and hatred wavering before slowly collapsing onto his knees, unable to push forward. Izuku was proving to be much too strong for him to overcome despite everything that had been given to him.

"How…. Why?" whispered Tenko as he felt himself fading.

Suddenly, another memory flashed through him, but it was one completely unfamiliar to him. He saw a younger image of his father talking to someone via first person point of view.

'What? What is… or who is this?' questioned Tenko.

Izuku, still connected to Tenko, saw the memory as well and questioned what was going on.

The ground suddenly broke apart as an enlarged face of All for One suddenly came bursting from underground, threatening to swallow Tenko.

"How foolish!" roared All for One, "Did you think I would allow this to happen to my vessel? Tomura, you foolish boy, to this day, you've never made a single decision on your own!"

With a bite, Tenko's body disappeared into All for One's mouth as Izuku stumbled backwards.

"That hit almost put me into a coma, but thanks to your little rabble, I've managed to regain control once more! This is far earlier than I wanted to do this, but I suppose I have no choice thanks to your meddling," snarled All for One as the scattered remains began to form up to his image.

"Foolish Shimura Tenko," mocked All for One, discarding the original name he had given him, "No more than just a fragile ego, trying to cling onto your so-called life! I gave you a purpose, and you tried to bite me!?"

Tenko struggled as he tried to understand what was happening as he felt himself crumbling into pieces.

"As I said. None of your decisions have truly been yours. I merely made you think you did, otherwise you would have never attained such hatred and willpower," said All for One before explaining that his encounters with the 5th and 6th users of One for All taught him that he needed to surpass the users' willpower to secure it.

So he decided to cultivate one from birth, by finding Shimura Kotora. He revealed that he had been the one to convince his family to have another child, one who's quirk he promptly stole upon birth. From there, he controlled every facet of Tenko's life, all the way to bestowing him a quirk that he had modified and stripped it until nothing but decay and destruction before bestowing it on him when he disguised himself as an old man just helping Tenko back home.

He himself had been waiting outside, just waiting for the opportune moment to activate it, and smiled at the destruction that had been unleashed. As for the aftermath, he manipulated a few people to pointedly ignore him, created a zone with Tenko as the center to scare off other people, and hired some goons to bully him before pretending to be the 'nice guy' to gain his trust.

"Everything that has happened. Your tragedies, your trials, tribulations, rejection or acceptance, all came from me! You were just a puppet that danced to my whim!" boasted All for One, sinking the knife even deeper to Tenko's heart, "A mere chess piece, a pawn meant to be sacrificed! Now fulfill your role and disappea-!"

Before All for One could completely shatter Tenko's heart, a foreign object slammed into him hard, causing All for One to double over in pain and spit out what remained of Tenko. Nana quickly caught the still remaining parts of Tenko, cradling him to her chest.

"It's alright, I got you," whispered Nana as she tried to hold Tenko together, "Grandma Nana has you."

"Hope you didn't forget about us!" grinned Bruce, having been the foreign object that had slammed into All for One, "We've been itching for a rematch, and this time, we're the ones who outnumber you now, with you having nowhere to run!"

Bruce had been thrown via the other users, with Lariat using Black Whip to spin Bruce so he was a spinning bullet, and Kudo increasing his momentum with Gearshift. All while Bruce was repeatedly building up kinetic energy for his strike, creating a human bullet that smashed into All for One.

All for One glared at Bruce, intending to smash the man down when a giant fist slammed into his face, sending him flying back.

"Don't forget about me!" shouted Izuku, "We're all here!"

All for One growled as he faced the users of One for All. It was clear to him now that he needed to destroy the threat in front of him here and now. And with Yoichi managing the bridge between them, he couldn't force them out like he did before.

"No matter, you will all fall!" declared All for One.

The final battle was upon them.

If it wasn't obvious, the next chapter will be the final chapter for this war, and probably this story. I had no intention of going into the Dark Hero Arc and beyond. I'll have to flesh it out, but hope you guys are looking forward to it!

Reminder, I have a pat reon, look up azndrgn making fanfic. Donators get to read my chapters earlier!
