Alias: The Database An all-powerful entity. The ultimate existence. Even SCP-3812, who infinitely transcends the universe, is merely a record within the Database. Every living being inside this Database can be deleted from data at its whim. While it currently refrains from deletion, anyone who dares defy it will have their very existence erased from the data without a trace...

Alias: A Voice Behind Me The universe is endless and infinite. However, 3812 surpasses that universe and infinitely transcends the infinite cosmos. It is immune to all attacks, whether physical or dimensional, and all attempts to kill it fail. It can manipulate space and time, and is capable of dimensional restructuring or travel. It is said to warp time itself. It even ignores the Foundation's rules. It disregards the laws and abilities of all existences. It ignores deletion abilities, possesses high self-awareness, and has a sense of purpose. Thus, it is not a mere monster but a being capable of purposeful and strategic judgment.

SCP-2747 is an entity that blurs the boundary between reality and fiction. It manifests non-existent media or stories as if they were real. People begin to perceive fiction as actual existence. The relevant narratives and records gradually vanish. It is associated with black thorns and the symbolism of 'Seven'. It distorts perception and memory, making its presence difficult to detect. It is extremely difficult for even the Foundation to completely eliminate or contain.

Alias: Attempt to Look Upon What We Have Wrought SCP-4010 is a phenomenon where the attempt to organize the Foundation's history distorts reality. It eliminates chaos from the world in an attempt to impose order on reality. As the timeline progresses, anomalies and the Foundation itself disappear. Eventually, only Madeleine Sailer remains as the sole individual with knowledge of the Foundation. All traces of anomalies and the Foundation vanish from reality.

Alias: The Escapee SCP-3125 is an extra-dimensional entity that erases the perception and memory of life through information-based attacks. It traverses all realities and dimensions, exerting influence the moment it is perceived. It is an immortal being that cannot be eliminated by physical attacks or other methods. The mere attempt to understand this entity leads to self-destructive consequences. The only response is to block or delete information. Simply recognizing its existence can put one in grave danger.
