Supergod: The Foundation, Starting with Fabricating SCPs

"I still haven't found a perfect cure for the 'pestilence'!"

"But don't worry."

"Although you're the carrier with the highest 'pestilence concentration' I've ever seen..."

"I'll treat you just like everyone else! Once I find a perfect cure for the pestilence..."

"I'll bring you back to life!"

As he spoke, SCP-049, the Plague Doctor, kept pulling surgical instruments from the medical bag he carried. Clearly, he intended to operate on SCP-610, The Flesh That Hates (Heavenly Principle version).

He was going to turn it into SCP-049-2 and keep it by his side!

The turn of events left everyone dumbfounded!

They thought, Come on, did he have to go that hard? He'd killed one Containment Object, and now he wanted to turn it into his puppet!

That was insane!

Still, they were curious too: what would a Containment Object become after the operation?

Destroying you was none of your business! SCP-049, the Plague Doctor, erased every living being in the Demon Slayer World with a single touch!

(First update. Please subscribe! Your support keeps me writing. The next update will be around five. I'll keep them coming today—at least five updates!)

The viewers stared at the livestream, afraid to miss even the smallest detail. They knew they might never see anything like this again.

One Containment Object was performing an operation to transform another.

It was almost unheard of.

Under the viewers' watchful eyes, SCP-049 had prepared his surgical instruments. Compared with last time, the sheer number of tools was staggering.

They nearly filled the vast, strange space.

Then, as everyone watched in anticipation, SCP-049 began the operation. At his touch, SCP-610, The Flesh That Hates (Heavenly Principle version), which had already turned to ash...

Began to gather again before their disbelieving eyes, forming tiny particles of flesh.

A closer look revealed a face on every particle, twisted as if in agony. They kept crying out for help...

Then the tiny particles of flesh gathered together in SCP-049's hands.

At last, they formed a blood-red lump of flesh the size of a fist.

Countless tortured faces overlapped across its surface, devouring, merging with, and biting one another...

All the while, they let out cries for help that turned the stomach.

SCP-049 looked at his "masterpiece" and sighed. In an extremely raspy voice, he said, "My skills weren't good enough!"

"This is as far as I could transform you!"

"But don't worry!"

"Once I find a perfect cure for the 'pestilence,' I'll heal you completely!"

He paused, then continued, "But I have a bold idea!"

"If it works..."

"I might find the perfect cure for the 'pestilence' ahead of time!"

"I'll fuse this world's Heavenly Principle with you!"

"What do you think?"

As he spoke, SCP-049 seemed to make up his mind. Before the stunned eyes of the viewers, he approached the Heavenly Principle Will...

And reached his withered right hand toward the dazzling sphere of light.

The viewers felt their scalps prickle at the sight. They realized that although they had repeatedly raised their estimate of the threat SCP-049 posed...

They had still underestimated him.

Containment Objects were Containment Objects.

They couldn't be judged by common sense. The danger they posed lay beyond anything the viewers understood.

SCP-173, Little Peanut, and SCP-096, Shy Guy, lacked intelligence and acted only according to their rules. But even SCP-049...

A Containment Object with intelligence that was even "friendly" toward humans...

Was more dangerous than they could imagine.

He had killed another Containment Object, SCP-610, The Flesh That Hates (Heavenly Principle version), then turned it into his puppet through an "operation."

And now he wanted to fuse this world's Heavenly Principle Will with SCP-049-2, The Flesh That Hates (Heavenly Principle version).

Who knew what would happen if the two merged?

What would they create?

[Sengoku: @SCP Foundation, you can't keep standing by. I have a feeling something terrible is going to happen. Stop SCP-049, the Plague Doctor, now!]

[Orochimaru: This is madness! SCP-049 is insane! My experiments are nothing compared to his!]

[Still, I want to see what the two would become if they merged.]

[Hiruzen Sarutobi: @Orochimaru! Don't even think that! I don't know what their fusion would create, but I know it would be a terrifying force.]

[If it got out of control, we'd be finished!]

[Vegapunk: Why hasn't the Foundation acted? Do they not care, or was this their real cross-experiment all along?]

[Child Emperor: If it's the former, the SCP Foundation is far too confident. But if it's the latter, then the SCP Foundation is even crazier than we thought!]

[Aizen: Maybe this was the SCP Foundation's true objective. Maybe they sent SCP-049 to the Demon Slayer World from the start...]

[For this very reason!]

[Miko: @Aizen, Master, that can't be right! Isn't the SCP Foundation's principle to protect people? Why would they do that?]

[Aizen: @Miko. Practice the method I taught you. Don't worry about anything else.]

[Miko: Yes, Master!]

[Empress: Is the SCP Foundation going to do anything or not?!]

[...]

The viewers frantically tagged the SCP Foundation, urging it to stop SCP-049. But the Foundation didn't stop him.

It didn't even reply.

Clearly, the SCP Foundation had no intention of engaging with them.

Put bluntly, its silence told the viewers: Who are you to give us orders? Just watch the livestream and stop thinking you matter.

Whatever your status in your own worlds...

Before the SCP Foundation, you're nothing!

In the universe, the greatest show of respect was to wipe an enemy out. The greatest contempt was to ignore them. Would a dragon bother with a swarm of ants?

No!

The viewers gradually realized this. They stopped shouting and watched the livestream in silence.

Onscreen, SCP-049 gently touched the Heavenly Principle Will of the Demon Slayer World with his withered right hand. As the viewers stared in shock...

The countless brilliant threads within the enormous sphere of light rapidly lost their luster.

They turned into specks of starlight and vanished into the void.

At the same time, a split screen appeared in the upper-right corner of the livestream, showing the Demon Slayer World. Onscreen...

At the Demon Slayer Corps' hideout, the Wind Hashira, Sanemi Shinazugawa; the Stone Hashira, Gyomei Himejima; the Mist Hashira, Muichiro Tokito; the Flame Hashira, Kyojuro Rengoku; and the others had gone into hiding on Kagaya Ubuyashiki's orders...

They were discussing what to do next. A moment earlier, they had been furiously swearing to avenge Kagaya Ubuyashiki...

And to carry on his will, fighting Muzan Kibutsuji to the bitter end.

The next moment, every one of them collapsed.

Their lives were gone.

No matter how unwilling they were to die, how strong their resolve, or how deep their hatred... before SCP-049's conceptual erasure, there was only one outcome.

Death.

And it didn't end there. Their translucent souls rose from their bodies. Only then did they realize they were dead. Before they could speak...

Cracks spread across their souls, and within moments, they vanished completely.

Before SCP-049, there was no coming back to fight another day. Conceptual erasure was no joke!

Dead meant dead!

No method could bring them back!

That was the terrifying power of conceptual erasure!

Inside the Infinity Castle!

"Why didn't you fight with everything you had to gather information?"

Muzan Kibutsuji stroked Daki, who lay obediently across his lap, and addressed the Lower Rank Demons kneeling before him. "Or do you find those people more frightening than me?"

"I..."

As Muzan Kibutsuji's blood-red eyes swept slowly over the Lower Rank Demons, the suffocating pressure left them sprawled on the floor.

The excuses they wanted to make stuck in their throats.

They feared that one wrong word would get them killed by Muzan Kibutsuji.

But at that moment, the world suddenly fell silent. Daki, the demon boy, Kokushibo... even Muzan Kibutsuji lost their lives without a sound.

Muzan Kibutsuji's soul stared at the crumbling Infinity Castle below and at his own corpse. "Am I dead?" he asked in disbelief.

"That's... impossible."

"I'm immortal! I..."

Before Muzan Kibutsuji could finish, he saw Daki and the others' souls shattering. Alarmed, he looked down at himself!

His own soul was breaking apart too.

He had no time to cry out before he turned into specks of starlight and vanished into the void!

"I'm finally free!"

The Second Tsuchikage, Mu, watched his soul crumble and let out a long breath. "I hope what I did won't bring trouble to Iwagakure."

"I wish I could go home and see how the children are doing."

"Ah..."

With Mu's sigh, his soul broke apart and disappeared. Around him glimmered the fading remnants of more than a thousand ninja souls!

The Demon Slayer World's inhabitants and the lone adventurers also lost their lives without warning. They fell in swathes, like grass beneath a scythe!

Newborn babies, the oldest of elders, young people indulging their desires, high-ranking officials fleeing for their lives...

All of them died without warning in an instant.

Their souls shattered completely!

They were gone for good.

At that moment, every intelligent living being in the Demon Slayer World was conceptually erased by one gentle touch from SCP-049, the Plague Doctor.

They became nothing and vanished from the world!
