Super God: The Foundation, Starting by Inventing SCP

Naturally, they would not let their guard down around SCP-049, the Plague Doctor, just because of its appearance. Its name even contained the word "plague"!

That alone was enough to show how terrifying SCP-049 was!

Just then, detailed information about SCP-049 appeared in the empty space to the right of the image!

[Contained entity]: Plague Doctor!

[Item number]: SCP-049!

[Item classification]: Euclid!

[Appearance]: SCP-049, the Plague Doctor, is a humanoid entity resembling a medieval plague doctor.

Although SCP-049 appears to wear a black robe and a bird-beaked mask, its clothing and mask seem to grow from its body.

Tests have shown, however, that SCP-049's skeleton is still human.

At the sight of this information!

Holy Kesha froze. "Its clothes are part of its body, yet its skeleton is still human. The Foundation's contained entities really are bizarre."

As she marveled at this, new information appeared on the livestream.

[Verified by the Doctor: Under normal circumstances, SCP-049, the Plague Doctor, shows considerable goodwill toward humans and is very willing to cooperate with the SCP Foundation!]

Everyone in the livestream was stunned.

After seeing SCP-173, Little Peanut, and SCP-096, Shy Guy, they had assumed that, apart from SCP-343, God, all the other contained entities...

Lacked intelligence.

Never had they expected SCP-049, the Plague Doctor, to be intelligent and to harbor such goodwill toward humans.

Their eyes lit up.

Some even began wondering whether they could use that goodwill to bring SCP-049 over to their side while exploring the Demon Slayer World...

With SCP-049's help, exploring a little world like that

Would be a piece of cake, even if the Demon Slayer World had undergone some kind of mutation.

More importantly, they might learn about other contained entities and the SCP Foundation's inner workings from SCP-049.

But while everyone was busy making their own plans,

The next information to appear on-screen hit them like a bucket of cold water.

[However, the moment SCP-049, the Plague Doctor, senses what it considers a "plague" nearby, it will immediately become violently agitated!]

[SCP-049, the Plague Doctor, will display extreme hostility toward individuals it believes are affected by this "plague"!]

[Under normal circumstances, SCP-049, the Plague Doctor, will attempt to kill individuals infected by the "plague."]

[Method: A touch causes the target to die instantly. This ability is suspected to be conceptual in nature!]

[Note: The "plague" as perceived by SCP-049, the Plague Doctor, is not a plague in the usual sense. Foundation Doctors have conducted 123,000 interactive experiments with SCP-049!]

[They have yet to determine what SCP-049, the Plague Doctor, considers a "plague," or even find a pattern!]

After reading this, everyone in the livestream gave up on recruiting SCP-049.

They could only think, A contained entity is still a contained entity. Not one of them is normal. Even one that showed such goodwill toward humans

Would kill people for no apparent reason.

And its method of killing might even be conceptual. It was unbelievable!

[Monster King Orochi: If we can work out what SCP-049 means by "plague," it won't be dangerous anymore! Just like an allergy!]

[Orochimaru: You're right! But if the Foundation couldn't figure it out, what makes you think you can? Also, I hate your name!]

[Child Emperor: Think of SCP-049 as mentally unstable. It's friendly until an episode hits; then it kills without any discernible pattern.]

[Sengoku: On behalf of the Marines, I'm withdrawing from the exploration of the Demon Slayer World. A mutated world with contained entities in it? No matter how many Marines we send, they'll just be going to their deaths!]

[Aizen: I'm withdrawing my team from this mission too.]

[Momo Hinamori: Our captain really is a good captain who values his comrades' lives!]

[Hiruzen Sarutobi: Konoha is withdrawing as well!]

[Luffy: I'd like to go have a look! Nami...]

[Nami: Our captain doesn't want to!]

[...]

Just then, the livestream updated again! The new information left everyone silent.

More information about SCP-049, the Plague Doctor, appeared on-screen.

[Experimental observations show that within five minutes of killing someone, SCP-049, the Plague Doctor, often displays frustration and remorse!]

[According to the Doctor's research, these feelings are unrelated to the victim's species, age, or sex. They seem to correlate with the severity of the "plague."]

[After becoming frustrated or remorseful, SCP-049, the Plague Doctor, takes surgical instruments from the black medical bag it carries and performs "surgery" on the deceased target.]

[The Doctor has observed that its surgical instruments are far larger than the medical bag that holds them.]

In the hall of Demon Castle!

Morgana stared at the information, stunned!

This SCP-049, the Plague Doctor, was fascinating. It actually felt frustration and remorse after killing someone.

And then it performed surgery on the corpse?

What a freak!

Even her own Demon army was more straightforward than that! When her Demons killed, they killed.

Why would they feel remorse?

Unbelievable!

As Morgana silently mocked SCP-049, the Plague Doctor, for being childish, more information appeared in the livestream.

[Corpses operated on by SCP-049, the Plague Doctor, regain the ability to move.]

[The Foundation designates organisms in this state SCP-049-2!]

[However, SCP-049-2 cannot be considered "resurrected." They have no capacity for thought and are merely mobile corpses.]

[Under normal circumstances, SCP-049-2 remain quiet and move rarely, usually by walking.]

[SCP-049, the Plague Doctor, can command SCP-049-2 through an unknown means. This means is suspected to be conceptual in nature. To date, no method of severing the connection has been found other than completely destroying SCP-049-2.]

[Upon receiving an order from SCP-049, the Plague Doctor, SCP-049-2 immediately become unusually active. Experiments show that SCP-049-2 under orders no longer obey the law of conservation of energy.]

[They can carry out any order from SCP-049, the Plague Doctor, without consuming energy.]

[SCP-049, the Plague Doctor, usually describes SCP-049-2 as a rather imperfect "treatment." It has not explained what a perfect treatment would be!]

This flood of information left everyone in the livestream reeling.

By the time they had read it all, everyone had fallen silent.

They had to admit how laughable their earlier idea of recruiting SCP-049, the Plague Doctor, had been. It might have goodwill toward humans,

But it was still a contained entity.

Its abilities were at least as terrifying as those of SCP-173, Little Peanut, and SCP-096, Shy Guy. In some ways, it was even worse than both of them.

For one thing, SCP-173, Little Peanut, and SCP-096, Shy Guy, were terrifying,

But the rules governing when they killed were clear.

As long as someone did not break those rules, they were safe.

SCP-049, the Plague Doctor, was different. There was no clear pattern at all! It would attack anyone infected with the "plague."

But...

Who the hell knew what SCP-049, the Plague Doctor, meant by "plague"?

And that was not even the most important part.

Most importantly, SCP-049, the Plague Doctor, was intelligent! Intelligence meant limitless possibilities.

That made it far more dangerous than contained entities that killed according to fixed rules!

[Gecko Moria: SCP-049's ability is a lot like my Shadow-Shadow Fruit. We can both control corpses. I do it with shadows, though, while its method is unknown.]

[Kaido: One swing of my club would flatten you. Don't compare yourself to SCP-049.]

[Orochimaru: Impure World Reincarnation has a similar effect. In some ways, it's even better than SCP-049's ability. Its subjects retain their intelligence and memories!]

[S-Class Hero Zombieman: What if SCP-049-2 are the result of imperfect treatments? A perfect treatment might produce something far more terrifying.]

[They might even become contained entities themselves!]

[Child Emperor: I agree with Zombieman. And I have a feeling that if SCP-049 ever completes a perfect treatment, the consequences will be dire!]

[Vegapunk: I have the same feeling!]

[...]

At Yanhuang Academy, the many super soldiers stared blankly at the comments in the livestream.

When they first read the information, they thought they might be able to communicate with SCP-049, the Plague Doctor. After reading it all, they were speechless.

A contained entity really was a contained entity!

There was no making sense of how it thought!

It killed people, turned their corpses into zombies, and called the process treating a plague?

What the hell... Wasn't it completely insane?

After a moment's thought, Qilin voiced her idea. "Could SCP-049 have gone to the Demon Slayer World because it believes there's a plague there?"

"And it needs to treat it?"

Qilin's words made Rose and the others' eyes light up. She might be right. Perhaps that really was why SCP-049, the Plague Doctor, had gone to the Demon Slayer World.

Wait...

At that moment, Rose suddenly felt as though she had overlooked something.

But no matter how hard she tried,

She could not remember what it was.

Rose was not alone. Many others present, including powerful figures from the various native worlds in the livestream, also realized they seemed to have missed something.

But none of them could recall what.

Just then, the image of SCP-049, the Plague Doctor, vanished from the livestream. In its place appeared the slightly gaunt figure of Doctor Kuroto.

Beside him was a document bearing the [SCP Foundation] emblem.

Its title read: [Information on the Demon Slayer World and Speculation on the Cause of Its Mutation].

At the sight of it, every viewer held their breath, whether they still intended to explore the Demon Slayer World or had already withdrawn.

They had a feeling!

What Doctor Kuroto was about to say would, in some way, change the Super God Universe forever!

SCP-049: Young Man, I'm a Doctor. May I Treat Your Sister?

Under the breathless gaze of everyone in the livestream, Doctor Kuroto opened the document and spoke slowly to the camera. "Three days ago, the [Myriad Races Livestream] issued its mission for the Demon Slayer World."

"With authorization, base researcher Doctor Calvin then used the contained entities SCP- and SCP-, among others, to study the Demon Slayer World."
