Item #: SCP-XXXX
Object Class: Euclid Thaumiel
Special Containment Procedures: Due to the properties displayed by SCP-XXXX when exposed to mass populations, SCP-XXXX has been exposed to 7,542 D-Class, outfitted with mental implants allowing control of brain-wave functions. These individuals, known as SCP-XXX-1, are held in a modified Mass Humanoid Containment Cell, and are held in stasis by redundant IV and security systems. Modifications to SCP-XXX-1's mental implant objectives must be voted on by the O5 Council.
Description: SCP-XXXX is an audial cognitohazard. SCP-XXXX is physically impervious to damage, if the storage method is the last remaining copy. As of ██/██/20██, neutralization testing has been indefinitely postponed.
Upon audio exposure to SCP-XXXX to a sentient, living human, they rapidly transform into a Caucasian male, approximately weighing 66 kilograms and 1.8 meters in height. This figure is known as SCP-XXXX-A. SCP-XXXX-A responds to no external stimuli. Full transformation will occur in a period of time between 12 seconds and ██ hours.
SCP-XXXX-A can be terminated while transforming through any method that an uninfected individual could be. SCP-XXXX-A will seek out the nearest door as slow as 5, and as fast as 1,200 kph, depending on the distance. SCP-XXXX-A will phase through matter if needed to arrive at a door, as long as it is not near any sentient beings capable of sight. Upon SCP-XXXX-A's arrival at a door, it will knock three times. After knocking, it will utter the phrase, "█████". No significant links have been found between SCP-XXXX-A and the United States Department of Treasury. A female figure, dubbed SCP-XXXX-B will appear, and open the door. SCP-XXXX-B's appearance flucuates between appearances, with facial structure, clothing, jewelry, and speech fluctuating between appearances. If SCP-XXXX-B is one morphing figure, or if it is a collective of many of the same species is unconfirmed. SCP-XXXX-B will greet SCP-XXXX-A. SCP-XXXX-A will complain about an arbitrary issue. Recorded issues have included poor hygiene, uncleaned clothing, or other typical domestic non-issues. No pattern to these complaints have been found. After the issue is stated, SCP-XXXX-A will state [COGNITOHAZARD REDACTED], the audial cognitohazard triggering this event. All individuals within a radius of 7.62 meters will laugh at decibel levels unprecedented by any known humans (approximately one-hundred-thirty-five [135] decibels). SCP-XXXX-B demanifests after this point.
The affected individuals will transform into SCP-XXXX-A, and transport into the largest population center in a 50 mile radius. SCP-XXXX-A has been known to use public transportation, abandoned vehicles, sleds, and airplanes to reach their destination. SCP-XXXX-A's potential sentience is still unknown. When all individuals are affected in the population center, or when 5,000 individuals are affected, SCP-XXXX reaches stage 2.
Addendum: SCP-XXXX is now classified as "Thaumiel" as of Incident 5/XXXX-██
