About

Object Classes 🟢 Safe: A class where the properties are completely understood, and there is no concern about it moving on its own as long as it is kept in a box.

🟡 Euclid: A class that possesses its own will or intelligence, making its future actions impossible to fully predict.

🟥 Keter: A class with very strong hostility or anomalies, making it extremely difficult to keep completely contained even with the Foundation's power.

🟣 Apollyon: A class that cannot be contained by any Foundation technology and will certainly bring about the end of the world as a matter of time.

⚫ Thaumiel: The Foundation's "secret weapons" used to contain or neutralize other dangerous SCPs.

🔵 Archon: A class that could be contained, but is intentionally left uncontained because "containing it would make the world even worse."

Explained: A class where the anomaly has been understood through scientific advancement and proven to be a normal natural phenomenon.

Neutralized: A class that has been destroyed or has lost its anomaly, becoming completely ordinary matter.

Characters

SCP Foundation

🟢 Safe SCP-999: The Tickle Monster. A slime-like, friendly mascot-like entity that envelops those it touches in abnormal feelings of happiness.

↑ Countermeasure: It cannot move even a millimeter as long as at least one person is looking at it.

SCP-096: The Shy Guy. If you see its face, it will chase you anywhere and kill you without fail.

↑ Countermeasure: As long as you don't see its face, it just sits quietly, so it is kept in a completely dark room or a fully shielded steel container.

SCP-895: Camera Disruption. A cursed space that changes into extremely grotesque images when viewed through a monitor.

↑ Countermeasure: View it with the naked eye.

SCP-002: The Living Room. An organic, disgusting room where the furniture is made of internal organs.

↑ Countermeasure: Do not approach.

SCP-049: Plague Doctor. A medieval doctor who kills humans instantly upon touch and turns them into mysterious zombies.

↑ Countermeasure: The scent of lavender or physical restraint.

🔴 Keter SCP-682: Hard-to-Destroy Reptile. The ultimate lizard that hates all life and immediately adapts and regenerates regardless of the damage taken.

↑ Countermeasure: By keeping it constantly submerged in a hydrochloric acid pool, the speed of physical regeneration and destruction are offset, slowing its movement and keeping it in the room.

SCP-076: Able. A bellicose combat maniac, a dangerous man who repeatedly resurrects elsewhere even if killed.

↑ Countermeasure: "Completely destroy" the body with overwhelming firepower.

SCP-354: The Red Pool. An eerie pond filled with blood from which various dangerous SCPs crawl out one after another.

SCP-106: The Old Man. An old man with a mud-like body who phases through walls and drags prey into a decaying pocket dimension.

↑ Countermeasure: Screams of pain from youths in their teens to early 20s, or sudden changes in light. By the way, the sacrifices are Class D personnel in their teens to early 20s.

SCP-001 (Dr. Clef's Proposal): The Gate Guardian.

⚫ Thaumiel SCP-2000: Deus Ex Machina. A massive underground facility that resets the entire world to start over if humanity goes extinct.

SCP-3000: Anantashesha. A super-massive moray eel hundreds of kilometers long lurking on the seabed. The fluid it secretes when digesting humans is the raw material for "amnestics," which are essential for Foundation activities. Therefore, Class D personnel are regularly offered as food.

SCP-179: Sauelsuesor. A giant cosmic woman floating near the sun with hair 34km long. She acts as a lookout, detecting threats from space heading toward Earth and pointing them out.

🟣 Apollyon SCP-001 (S. D. Locke's Proposal): When Day Breaks. A post-apocalyptic SCP depicting a world where all living things exposed to sunlight turn into gooey masses of flesh, and most of humanity has perished.

SCP-4891: The Great Pestilence. An anomaly spread worldwide where touching an insect manifested by belief causes infection, leading to insects overflowing from the body and death by suffocation.

SCP-2317: A Door to Another World. The Foundation's first former Apollyon-class, where the final chain sealing an evil god is about to break.

🔵 Archon SCP-1661: Gremlins. A swarm of autonomous self-replicating machines (automata) that attach to aircraft in flight and dismantle their parts to take away.

SCP-6585: Community Dog. Loved as a pet by everyone in town; it is left alone because separating it would cause a riot.

🩵 Ticonderoga SCP-4444: Bush v. Gore. Aliens are hiding in US politics, but they are only monitored because removing them would cause the nation to collapse.

SCP-4270: The Great, Immortal Chevrolet. A car that continues to drive through outer space at ultra-high speeds; it has no actual harm to humanity and cannot be captured.
