[SCP-3125 has adapted to survive in a far more hostile ideological ecosystem than our own. As humanity has never naturally encountered a concept as aggressive as SCP-3125, the human mind possesses no evolutionary defenses against it.]
[Individuals overtaken by SCP-3125 become incapable of accepting "traditional" ideas, acting solely to propagate SCP-3125. Though their physical forms remain unchanged, they cease to be recognized as human.]
The chat group stilled.
O5-8's assistant.
The mutilated founder of Anti-Memetics.
They had been hollowed out.

Herta's fingers tightened around her teacup.
SCP-3125 wasn't just omnipresent—it rewired minds, spreading like a virus.
How do you fight something like this?
[Should SCP-3125 fully manifest, humanity's interconnected knowledge systems would allow it to envelop, conquer, and replace all human thought within 4 to 12 hours.]
[At this point, the abstract concepts of "humanity," "civilization," "culture," "society," and "family" would cease to exist. The Foundation has designated this possibility as an MK-Class End-of-the-World Scenario.]
(MK-Class Scenario: Total collapse of human consciousness.)
The multiverse held its breath.
Total cognitive annihilation.
Chat reactions erupted:
"HOLY F—KING SHIT. ERASURE OF HUMAN THOUGHT?"
"This thing isn't an anti-meme—it's an extinction event!"
"Now I get why it's Apollyon."
A Certain Magical Index Universe
The Magic Gods exchanged glances.
Earlier, SCP-3125 had seemed dangerous but manageable.
Now?
A hyper-aggressive meme complex:
Rewriting cognition like a virus.
Replacing all human thought.
Triggering MK-Class apocalypse.
And it wasn't even physical—just an idea.
"How do you kill a concept?" one whispered.
"You don't," another replied. "It kills you."
[Multiple Foundation technologies can capture aggressive meme complexes, but all fail against SCP-3125's automatic defenses.]
[Fully perceiving SCP-3125's true form allows it to perceive you. It then attacks—a process partially physical, though mechanisms remain unknown.]
[Individuals mentally or ideologically linked to the observer (research teams, family) are also targeted. All knowledge of SCP-3125 and its attacks is erased—a "numbing" effect akin to mosquito saliva, masking its presence until full manifestation.]
[Foundation personnel can escape by immediate amnestic treatment. However, the only safe way to observe SCP-3125 is within specialized containment units. Outside these, even reading about SCP-3125 is a lethal cognitohazard.]
Marvel Universe | S.H.I.E.L.D.
Nick Fury exhaled. "So that's why the amnestics worked."
Natasha frowned. "If nobody knows about it, does that neutralize the threat?"
Fury shook his head. "SCP-3125 spreads itself. Like a virus seeking hosts."
The real question:
How do you contain something you can't even know about?
[SCP-3125 can be neutralized by a device proposed by the late Dr. Bartholomew Hughes: the Fictional Amplifier.]
[However, constructing it requires knowing its purpose—which necessitates awareness of SCP-3125, a death sentence. No method exists to neutralize SCP-3125 using only on-site resources.]
The chat group fell silent.
The Fictional Amplifier could work.
But Anti-Memetics is gone.
And Dr. Hughes? Forgotten.
[Relevant findings from continuous analysis:]
SCP-3125's indirect effects are detectable by any well-equipped memetics program.
Memetics research has declined catastrophically.
Eight years ago: 400+ organizations studied memetics (governments, militaries, corporations, universities).
Now: Only the Foundation's Anti-Memetics Division remained.
Almost no one notices this collapse. The disappearances have no explanation.
Detective Conan Universe | Police Headquarters
Conan's blood ran cold.
All those groups—wiped out by SCP-3125?
Then the next lines confirmed it:
[All these organizations were consumed upon discovering SCP-3125—the inevitable fate of advanced memetics research.]
[Anti-Memetics survived via training and preventive amnestics. Yet from 4,000+ members in 2012, it dwindled to 125 by 2015. By year's end, that number will approach zero.]
[Physical infrastructure suffered similarly. Once a global network, now only Site-41 remains. The original HQ at Site-167 has vanished from collective memory—presumably erased by SCP-3125's "cleanup effect."]
Three-Body Universe | Earth
Luo Ji's hands trembled.
"Cleanup effect."
SCP-3125 didn't just kill—it erased its victims from history.
No traces.
No witnesses.
Just silent extinction.
The archive ended.
Fear crystallized across the multiverse.
Facing SCP-682 or the Deer was one thing—at least they were tangible.
But SCP-3125?
A ghost.
Death the moment you perceive it.
And yet—Anti-Memetics fought it anyway.
Sherlock Holmes Universe
Watson finally broke the silence. "We understand SCP-3125 now. But one question remains— what happened to Anti-Memetics?"*
Holmes stared at the screen.
Did they fail?
Did MK-Class happen?
Then—a final document appeared.
A personal log.
Date: 30/11/2015
Author: Dr. Marion Wheeler, Head of Anti-Memetics.
[The outcome is clear. Hope exists.]
[Site-41's B30 wing was built to house Dr. Hughes' Fictional Amplifier. While construction continued, the rest of us fought an unconscious war—delaying defeat as long as possible, buying time.]
The chat group leaned in.
The Fictional Amplifier.
Had they really built it?
