SCP-1762: “Where the Dragons Went” is the parallel ‘Fantasy’ dimension that exists inside a small box. In medieval times, people believed in dragons because they actually existed. However, most adults in modern times don’t believe dragons are real. Thus, the dragons have lost their power, and can only manifest as origami.
SCP-610: “The Flesh that Hates” is a virus that turns humans into zombie-like creatures made of meat and scar tissue. The virus eventually terraforms the environment, turning everything into an organic hive-mind. The virus is said to have been created by the ‘Sarkic God of Flesh,’ which certain people worship in a cult.
SCP-1875: “Antique Chess Computer” is a functional (read: haunted) Victorian chess automaton. When anyone plays against it, the automaton installs a virus onto their home computer which supernaturally forces them to play chess… forever.
SCP-706: “Perfect Porcelain Doll” is a 12-year-old girl whose skin is made of porcelain. She compulsively attempts to maintain her appearance, becoming frustrated and self-destructive when not provided the materials to do so.
SCP-682: “The Hard-to-Destroy Reptile” is a large, reptile-like creature that is constantly growing. It has a hatred for all life, and is extremely dangerous and intelligent. Its containment procedure involves being dissected, tested upon, and submerged in hydrochloric acid until it is incapacitated.
SCP-173: “The Sculpture” is a creature made of concrete and rebar. It is animate and murderous. However, it is unable to move while being observed. Two Foundation personnel must watch the sculpture, informing each other before even blinking, while the third person cleans its containment cell, which is always mysteriously dirty.
SCP-507: “Reluctant Dimension Hopper” is a visibly average human male who teleports into parallel dimensions involuntarily. The location and duration is random. Despite this, he is happy to share information about his latest “forced vacations” with the Foundation, and even thinks of himself as a superhero.
SCP-3002: “Attempts to Assassinate Thought” is a contagious, parasitic memory. Early symptoms include falsely remembering events which never actually occurred. Eventually, the cognitohazard completely overwrites a person’s memories with fake ones. This causes the person to forget everyone and everything they know—including themselves.
SCP-4000: “Taboo” is a jungle inhabited by nameless, shape-shifting flora and fauna. If humans who enter give a name to an entity, it will steal that their name—thus assuming that person’s identity.
SCP-4105: “They Came from the River” is an event wherein a local University’s river suddenly runs backwards after a storm. Creatures made of water emerge from it, drowning civilians with their watery appendages.
