In Izuku's headspace, a conversation was taking place. "This is a problem. They know Izuku is Toshinori's successor; it will only be a matter of time until All for One steals the world's quirks, and then he will have no problem getting Izuku to give One for All to him." Shimura told Fifth.

"We have to do something!" Fourth said.

"What's that?" Sixth said, pointing at something enroaching upon their headspace.

"It's someone else's shared headspace; it's close to a third shared headspace, and so is bumping into ours." Shimura said. All headspaces shared the same plane of existence. Shimura looked over at the two boys who had appeared, arguing.

"I can't believe you did that!"

"What else was I supposed to do?"

"It wouldn't have hurt him!"

"How was I supposed to know that?"

"Do you really think that little of me?"

"Considering what you had just said, at the time, yeah."

"You actually thought I was--"

"Frick. Touya's going to kill us."

"We just have to do our best, okay? If we play this carefully, I bet we can fix everything all by ourselves."

"What about Tenya?"

"All for One probably has a mind-reading quirk."

"We're doomed."

Shimura turned to the others.

"We should tell Bakugou about this." she said.

Katsuki and Izuku sat together, staring listlessly at the wall.

"What do we do now?" Izuku asked. Suddenly, Katsuki looked up, eyes fixed on something only he could see.

"Wait. What?" he asked. There was a moment of silence.

"You're sure?" he asked, again. After another pause, he sunk his head into his hands.

"Aaaaaaaaaaa..." he said, and then disappeared in a green flash.

"Where'd he go?" Tsukauchi asked.

"No idea." Izuku said, and then he disappeared in a flash as well. Tsukauchi remembered something Bakugou had said after the USJ; 'I have magic powers.' Whether that was true or not (and it was), there was something strange going on.

"Everyone! Meet our UA traitor--and he brought us some new Nomu material!" Shiagaraki said, walking out of a portal

with Denki,

and Shouto.

Touya's mind blanked. The world roared past his ears, and the only thing he felt was fury.

"The number seventeen hero's son? Good job. Anything else?" All for One asked.

"[Nope, noth]--oh, there's something. Dabi--[shut up]--is working for the heroes--[what are you doing]--as is Hawks--[NO STOP]--Best Jeanist's still alive [what the frick is wrong with you?]" Denki said, switching tone multiple times.

"Oh! Are you like me? [That would suck.]" Twice said. Touya launched a massive plume of flame at Denki, but the floor reached up and wrapped around him, as well as Hawks. "I was aware of this already." All for One said.

"What?" Hawks shouted.

"You are not nearly as discreet as you would wish. Now, let us continue." All for One said.

"That's Ingenium's brother." Denki said, looking at Tenya, who was tied to a chair on the far wall.

"I captured him. All for One will destroy all these pathetic heroes, and we will help him rule the world. Mwhahahaha!" Bruce said, gesturing expressively. Touya struggled, but could not burn his way out.

"You sound like you took those lines from a play [you're one to talk]!" Denki said. Bruce stiffened.

"Excuse me? I will have you know I am as much a villain as you, and intend to see this crusade of darkness to the end!" he said, shoving his finger in Denki's face. Denki blinked.

"[Did you actually just say tha--] He's--he's like I am to you!" he said, and an odd look passed over his face.

"[You sure?]" he asked himself. Frick, Denki was completely insane, Touya realized. How had he hid it for the whole year?

Then, there was an explosion.

"KAMINARI DENKI!" Katsuki screamed, blowing open the door. Oh, no.

"You killed HalfnHalf. I'm going to kill you, you Tuesday Bastard!" Katsuki yelled. What?

"You can try [what did you call me?] but you'll fail." Denki said. Katsuki hurled an explosion, wrecking half the room, before dashing towards Denki, screaming. Denki dodged, electricity crackling from his fingertips.

"Leave, you idiot! You're going to die!" Hawks yelled. Katsuki snapped with explosions, barreling right over Shigaraki. For a moment, it almost seemed as though he would win--but then a black lance jutted from the ground, straight through him. All for One flicked his finger again, and the lance disappeared.

"A good try, but ultimately futile." All for One said, as Katsuki sunk to the ground, and blood pooled across the floor. Two students were dead, and one was captured, and

it

was

all

Touya's

fault.

A look of horror passed over Denki's face, but it quickly disappeared.

"I would have liked to deal with him myself [HE'S DEAD KATSUKI'S DEAD] but I suppose it was unnecessary." he said. The armoured villain, Bruce, looked slightly sick. "Not...dead...yet. Haah." Katsuki gasped, and grimaced. "You will be soon." All for One said, and pointed to a camera that had been broadcasting to the entirety of Japan before placing his hand on a small box-shaped machine that sat on the table.

"People of Japan. This device is almost finished powering up; by five minutes after midnight, it will be, and all your quirks will be mine. The heroes cannot stop me; even now, they attempt to battle their way through my fortress, but the traps are too much for them. Even should they reach this room, I could kill them in an instant, and I have a hostage, for extra insurance." All for One said. Not too far away, a Nomu roared, and someone walked through the remains of the exploded door.

"KACCHAN!" Izuku screamed.

"People of Japan, look upon your hero: this child is All Might's successor. Unfortunately for him, he is nowhere near the level of power the other once held. There are only five minutes until midnight, boy. If you hand over your quirk now, I may spare your life." All for One told Izuku.

"Kacchan, don't die!" Izuku cried, before glaring at All for One with a ferocious anger, his green eyes shining like emeralds.

"It'll...haah...be four...times now. Give that bastard a good beating for me, huh?" Katsuki said to Izuku, his breathing becoming shallower.

"I will stop you, All for One; for Kacchan!" he yelled, and then, lighting up with brillant electricity, aimed a kick at All for One's face. All for One reached out, twisted, and slammed Izuku into the floor.

"There's nothing you could possibly do to me." All for One said.

"You can't do anything to me either, not if you want to keep me alive for my quirk!" Izuku growled.

"I could turn you into a Nomu, but I'd rather not, true. Oh, there is something I can do, actually. Kill the hostage." All for One said. Shigaraki turned towards Tenya, hand outstretched, but Bruce pulled a knife and stabbed Tenya in the chest. Blood dripped down his white armour.

"Awww. I wanted to decay him." Shigaraki said.

"TENYA!" Izuku screamed, and ran towards his friend, who sat as silent as before--he hadn't moved once, while sleeping, and wasn't going to move now.

"Don't bother. You are doomed; we are inevitable." Bruce said, and laughed menacingly. Izuku rushed towards the machine, which Denki was standing next to; Denki stuck out a foot and tripped him. All for One grabbed Izuku's leg, and twisted.

"OW ow ow ow!" Izuku screeched, swinging and missing at his enemy.

"That should have broken your leg. I thought you had only one quirk." All for One said.

"I guess I still have some of Kacchan with me," Izuku said, kicking All for One in the chest. He stumbled a step backward, dropping Izuku.

"That cheater! I told you he used illegal mods! Good thing he's done for. You dead yet?" Shigaraki asked the boy on the floor.

"Nearly...you bastard." Katsuki answered, breathing heavily.

"I'll save you!" Izuku said, punching at All for One again. All for One caught his fist.

"Why are you even trying?" All for One asked, throwing Izuku into the structure holding Touya. It cracked a little, something only Touya noticed, as Izuku stood up, shakily.

"One minute after midnight." All for One said. Izuku kicked the wall, and the camera went dark. All over Japan, millions of people stared at black screens, wondering.

Izuku made a few more useless attacks towards All for One, and Katsuki breathed his last shuddering breath.

"NO!" Izuku shouted, kneeling beside his friend, hardly daring to touch him. Katsuki lay still.

"Five minutes after midnight, and your friends are dead." All for One said. Izuku stood up, his hero costume covered in blood and sweat.

"You never stood a chance. Whatever plan you had was always doomed to fail." All for One said, then turned to the device, placing a hand on it. Denki stepped back, mouth twitching nervously.

"You're wrong." Izuku said, a ghost of a smile gracing his face.

"Really? Explain how; if there's a way you could beat me, even now, I would love to hear it." All for One said, as the device lit up and spun.

"I only ever needed eight seconds." Izuku said, and though he was covered in blood and tears, he smiled. He ran towards All for One, who lazily lifted a hand to stop him. At the same time, Touya exploded from his restraints, sending a wheel of blue fire spinning towards All for One--and Tenya, with a Recipro Burst, dashed from the chair he'd been tied to. Bruce collapsed for no apparent reason, and Tenya leaped into the air, swinging his leg around at an incredible speed. All for One turned to look at Tenya--and stopped.

"How...?" He reached, for Dark Spikes, for Search, for Shatter, for Fire Breath, for All for One itself, but found himself as quirkless as Izuku had once been.

"I reversed your device!" Denki shouted. There was a triumphant smile on his face--so different from the malicious ones he'd been previously sporting.

Izuku's breath caught in his throat.

Tenya's foot slammed into All for One's head, Izuku punched him so hard there was a shockwave, and a burning line of blue fire seared through the air. Quirkless, All for One could not defend himself, and Japan's greatest villain fell.

"Take that, bastards!" yelled Katsuki, exploding all the other villains into a cage that he had formed from the walls with his. None of them could get out, and Shigaraki, who would usually be able to decay the walls, strangely couldn't.

"NOMUS! SAVE US! KILL THE HACKER!" Shigaraki screamed, and a veritable army of Nomus ran into the room--but the wall exploded with fire, and Shouto, riding on a wave of ice, flashfroze and incinerated them in one fell swoop.

Notes:

details! are! important!

you may have noticed that I specified that Denki hit Zuko on his cold side, which proceeded to launch Zuko's soul into Denki's body. He thought he was doing something incredibly intelligent by shooting low voltage at Izuku to pretend that he really was on Shigaraki's side, but Zuko interfered, "died", and made it worse.

everything will be explained in detail in the next chapter!
