Author's Note: Ok, so I've posted this chapter before, and the last time I did it got a tonne of flak. So at the risk of spoiling future stuff, guys relax a little. I take great pride in bending the rules of the OG manga in this fic without outright breaking them, I'm not going to start now.

Saitama's POV

"Maaaaannnnn, this is boring." The B-Class flopped down to the floor, staring at the white ceiling. For some reason, instead of falling asleep normally like he did normally his consciousness was trapped in some sort of giant pinkish-white room with thousands of floating lights. All of them had some sort of memory. Most of them were mundane ordinary memories, but he had also found his memory of fighting the centipede and the memory of him meeting Genos. Mixed in with those lights were a few purple ones, that showed several types of monsters being fought.

"Well, now you know how I felt."

The B-Class turned around to see… himself, but completely dark blue and transparent.

"Don't be so impatient. I tolerated this for years, you only have a few more hours to go before I awaken and you're free. I was even nice enough to let you see my memories."

The bald man sniffed, looking into one of the orbs, which depicted some fat Monster with one eye tossing rocks.

Oh, that's Psykos. Some small fry, not important.

He looked at another memory. "Hey, isn't that that sassy child from the meeting?"

Yes, He pauses for a moment to rub his completely bald head. She would have made an excellent host, in fact if not for her less than intimidating appearance a perfect one, if I hadn't found you.

"Soooooo… why did you choose me again?"

I don't mind telling you my plan, since you won't be around to resist me. After we defeat the last few people, the sumo first, I'm going to-

Sairama waited for a few moments. "Going to?"

The B-Class turned to see that the being had vanished.

Zhiznucrast's POV

My my.

The immemorial spirit looked around the area he found himself in. A gigantic field of flowers stretching as far as the eye could see. A clear sky. And a giant figure staring down at him.

You made all this just to see me. I'm touched.

In the distance, a massive being comprised almost entirely of veins stepped forward.

It's been a while, hasn't it, God.

Yes. You seem satisfied.

Why wouldn't I? Our war is finally at an end, soon I will be victorious.

We have battled for thousands of years. Are you that confident in this one… specimen that you would cast aside your power, your abilities, your freedom, for-

Don't lecture me. If you could destroy me you would, but you cannot. Not while he shields me.

You will suffer for your arrogance.

No, I won't. If you have the power to destroy his body, go ahead. Come at me with all your might.

The figure remained silent.

You would oppose me.

I would. Your servants are weak. Homeless Emperor is but a gnat to me, lesser than that in fact. Whatever other agents you possess cannot be stronger than that. You are powerful, yes, perhaps more powerful than me, but not more than him. Nothing is more powerful than him. And now we are one.

He cannot shield you forever. There is a reason you did what you did to Blast, a body cannot sustain you for long, no matter how strong. Even if it could it would require... sacrifice.

The deity's voice was laced with smug satisfaction. No doubt it thought that that alone guaranteed its victory, the supposed fact that sooner or later he would have to leave Saitama's body.

You think you've won? Look at you, so smug, oozing with confidence in your ultimate victory. I would humour you, but I have no time for that. There is no victory, there is no conceivable scenario that could exist, no conceivable strategy that you could use, to destroy him.

He pulled out the intact faceplate of Demon Cyborg, and held it up.

Earth, is mine.

Genos's POV

The Demon Cyborg looked at the display. Two distress signals. Watchdogman and Zombieman were both combatting a threat? And from the looks of it Watchdogman had been defeated, judging from his signal's lack of movement.

This power… was it Sensei's? It would certainly explain the massive damage being reported and the fact that Watcdogman had been so quickly incapacitated.

It didn't matter. Irregardless of whether or not it was Sensei, this was the best time to test his new combat abilities. He would defeat this new threat. Turning, he sped off into the distance.

Zombieman's POV

"Oh? Do you intend to challenge me? The weakest S-Class against somebody who has defeated some of your strongest?"

The immortal sucked in another breath, mind racing. He had arrived just in time to see the Being no-sell a blow to the head from Watchdogman and kick him into the distance. And it was clear from the few ineffective blows he had managed to land that that was no fluke.

"That immortality sure is troublesome. Even if I tear you to shreds you'll just regenerate, with nothing to show for my efforts except for your clothes. Oh wells, maybe there's a limit. I'll have to test and see."

Before he could blink his legs and arms were torn off, there was a massive hole in his chest, and most of his internal organs were now splattered over the streets.

"If only I didn't know that reducing you to mincemeat would kill you, I could just end it in one punch. Doesn't matter, you can't do anything anyway. For now, just sit here and watch out for any newcomers. Honestly, there's only one other person I can see coming here, but he probably won't be here so soo-"

"Justice Crash!"

Mumen Rider's POV

"Don't be crazy!" The C-Class ranked 1 struggled against his fellow Heroes as they tried to hold him back.

D-Pad wrapped his arm around his neck. "That thing just took down two S-Classes and destroying buildings in a single blow! We can't do anything against that! Just wait for the other S-Classes!"

"No! We have to do something!" Mumen tried to pry their hands off him, but it just lead to them grabbing on to his arms instead. "If we don't he'll destroy everything! Kill everyone!"

"Ending up as a blood stain won't help anyone!"

The ground trembled, and everyone collapsed to the ground in a heap.

Before the rest of them could regain their balance, he pushed himself to his feet and ran forward. He snatched up his bicycle frame, which he had stubbornly dragged along to be fixed later, and tossed it at the Monster.

"Mumen no!"

He gritted his teeth as he neared it. Even if this thing looked like, no, even if it was Saitama, he couldn't let himself get distracted. He had to defeat right here right now!

"Justice Tackle!" He lunged forward, but he knocked into it and crashed to the ground fruitlessly. Undeterred, he sprang to his feet.

"Justice Kick! Justice Punch!" He aimed his blows at the creature's stomach and ribs, but it was like hitting a wall, immovable and painful.

"Justice Tackle!" To his surprise, the Mysterious Being actually took a few steps backwards this time.

"Justice Punch!"

The glow flickered. Was… was he beating it?

The Being sighed, and placed its hands on his collarbones.

"Before we end, I would just like to express my deepest condolences. Do not worry, I will personally ensure that your legacy will be remembered. Farewell."

And the Being pushed him back, his last feelings being his body crumpling against the rubble behind.

Saitama's POV

The B-Class's eyes snapped open.

What the fuck?

Mumen Rider was in front of him, enormous shards of concrete jutting from his chest, unmoving, massive pools of his blood pooling around his feet.

He gaped in shock, tentatively reaching out. "Mumen?"

Something clinked against the ground. He looked down, and to his shock Geno's faceplate was there as well, buried within the rubble, itself stained black and red.

You did this.

"What?"

You killed them.

"Me? I-I couldn't have, how…"

Spots danced in front of his eyes, and a hand burst out of his forehead and pushed on his face. Just before he blacked out, he heard a man scream for him.

Zombieman's POV

I need to… get up. The immortal pushed himself to his feet. The tendons within had yet to grow back, but it didn't matter. I need to… blinding flashes of multicolored light filled his vision.

Wha- what was happening to that bald man?

A sonic boom echoed through the streets, and a cyborg crashed landed.

Demon Cyborg?

"Sensei!"

"Arrrggghhhhh!" Multiple limbs erupted from his head, and with a burst of light the unkillable S-Class was sent flying backwards.

Out of the smoke crawled a transparent bald man, shining an assortment of colours, with no Caped Baldy in sight. It threw its head back and screeched.

"I'm free!"

Geno's POV

The Demon Cyborg regarded the scene in front of him in horror. Mumen Rider impaled, Zombieman reduced to mush, and his Sensei's attacker whole, with his Sensei nowhere in sight. Frantic, he scanned for his Sensei's life signal.

Scan result: Negative

"What… what have you done to Sensei?"

The Monster brushed something off its shoulder. It looked exactly like Sensei, only with horrific scarring across his face, fire damage in large patches across his suit and short, spiky hair across his scalp. "Oh, I simply sent him far, far, far away. Rest assured, when this is all over, I'll find his body and bury it."

"What have you done to him!"

The Monster casually kicked Zombieman into the distance, before turning back to him.

"Did you ever wonder why I could only possess your Sensei when he was asleep, and even then not fully? There is something Saitama has that nobody on Earth has, his indomitable willpower, coupled with his near-limitless strength. Even against the mind defences of the psychics like Fubuki or Psykos, or against the immense power of Orochi or Tornado, I could have possessed any of them with ease. In fact, I would have possessed them, if Blast wasn't such a suitable host for so long."

Blast? The S-Class ranked 1?

"Well, that's all in the past. All that's important is that Saitama was too strong to possess. To take him would require either weakening his strength or his will. For a while the only way to do either was for him to sleep, removing his conscious defenses and allowing me to tap into a mere trickle of the vast ocean of strength he had. Even then it wasn't much, I couldn't kill, I couldn't do anything too difficult, I couldn't even use my other stockpiled powers." The Mysterious Being twirled his fingers, and trails of fire and wind swirled around him. "True, most of them are pointless with him, but it would have been nice to still be able to fly."

"Until now. Your Sensei is far from as stoic as he believes himself to be. Well, maybe I have you and Mr King to thank. When I told him that he was the one who killed both you and Mumen Rider he was shocked, horrified. He may not have shown it, but to me, who felt his every emotion, he may as well have been weeping. And in that moment, when his mental defences were down, I struck."

It spread its arms out in a gesture supposed to be grandeur. "I am Saitama now, Genos. When I escaped him I permanently gave up my power to leap between bodies. In exchange I have absorbed all of his power.

"How do I get him back?"

"Saitama's gone Genos."

"How do I GET HIM BACK!"

"He's gone, forever. Another victim which you failed to save."

"Arrgggghhhh!" The S-Class burst forward, using his rockets in his elbow and feet to smash a fist into the monster's chest, who simply slid back several meters, unperturbed. He flew into the air and burst down, cracking the street in a hundred meter radius but missing the Being, before charging his cannons.

"Maximum Power! 100%!" He didn't care if he was going to kill himself while doing it, he was going to avenge his Sensei.

"Genos, why are you attacking me? You don't want to weaken me now, especially not with what I'm about to do."

His guns faltered. What was the Being going to do? What could it possibly do that could make what it did excusable? Spare it his wrath? Whatever, it didn't matter, it was a trick! He was going to kill it! His guns hummed as he powered them up. However, despite this the Mysterious Being turned around and walked away not caring if he replied, only giving him a parting backwards glance.

"I'm going to destroy the Monster Association."
