SCP-6789-AC

## **`DESCRIPTION`**

SCP-6789-AC is an entity that takes on the appearance of a 12.2 meter (40 foot) tall bipedal humanoid figure with brown, mummified skin, long arms with clawed hands, and two head-like appendages in the shape of what appear to be sirens or megaphones, atop a long, stick thin neck.

The entity, dubbed "Siren Head" by the SCP Foundation, is estimated to be able to travel at a speed of 39.1 kph (24.3 mph) while on foot, and at speeds exceeding 415.6 kph (258.2 mph) on all fours. It possesses strength proportionate to its size and shows an extreme resistance to traditional gunfire.

Siren Head's most notable trait is its ability to mimic other sounds, such as ambient background noise, to human speech. In its resting state, it has been noted to play a continuous stream of white noise. While hunting, it appears to use its ability to lure in prey. It uses sounds typical of its environment to lure in local prey. It also seems to have an innate understanding of human speech and how to use it as a means of capturing human prey. Whether it understands the sounds it is duplicating, or is merely playing back what it has learned from observation, is unclear. It is also capable of utilizing its sound offensively if threatened, emitting sounds of high enough intensity to shatter ear drums and, in the worse case, cause internal rupturing, leading to death.

It lacks any discernible sensory organs, yet despite its lack of eyes, it is fully capable of detecting the presence of living organisms. After extensive testing, it has been determined that SCP-6789-AC detects a lifeform's body heat to hunt.

SCP-6789-AC was first discovered after reports of an inhumanly tall entity reached Foundation ears on November 2, 1966. However, after a task force was dispatched, following a trail of disappearances for several weeks, the trail went cold. SCP-6789-AC once again landed on the Foundation's radar on October 31, 2018, after several strange disappearances were reported in the Himalayas, Nepal in southern Asia. Several teams were dispatched, to investigate the local areas. However, after approximately 48 hours, the radios suffered extensive feedback and blew out. A Foundation strike team was sent in as backup when communication couldn't be restored. It was then that the strike team reported the previous teams, a total of eighteen Foundation officers, had all been killed. After a short while, the strike team located and provided first visual conformation of SCP-6789-AC. The strike team tailed SCP-6789-AC from a distance while four additional teams of six were sent in for support. In the end, via use of heavy explosives, SCP-6789-AC was incapacitated and brought into custody, having cost the lives of twelve additional Foundation personnel.

A series of prehistoric cave drawings dating back to at least 43,900 BCE were later discovered, depicting SCP-6789-AC in a simpler state, giving rise to the theory that SCP-6789-AC is capable of adapting along with its environment, accounting even for human-made occurrences and creations, such as electronics, machinery and technological progress in general.

Any sources indicating that Siren Head is not an SCP are false and should be dismissed as such.
