Cryptid Overview

She was on vacation with her husband and they were scoping out graveyards on the way, as you do, when she saw it. Rising out of the old cemetery, big as an old (macabre) telephone pole. Was this some kind of bizarre art piece the authorities hadn't gotten wise to yet? Even as she stepped out of the car, the megaphones on it's "head" screeched to life. "NINE. EIGHTEEN. ONE. CHILD. SEVENTEEN. REMOVE. VILE.". A buzzing, doubled voice screamed random words at her. At this point, it jerked into motion, striding down the hill towards her.

Siren Head is a fictional-being created by the Canadian artist respectfully known as Trevor Henderson. It is a 30 meter tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh with a color similar to rusted metal. emaciated being with a pair of sirens. Capable of emitting various noises both natural and man-made, including sirens, radio broadcasts, white noise, and human voices.


The Past

Siren Head was firstly introduced to the world in 2018, when Trevor Henderson created a Tumblr and Twitter posts, in which he published Siren Head for the first time. On October 31st, 2018, a group of game developers which are known as Modus Interactive, released a horror game for Siren Head, boosting it's popularity even further, and On December 7, 2019, a developer known as Thuleanpaneton, created his own Siren Head horror game too. The video-games highly influenced Siren Head's gain in popularity, it was even proposed to the SCP Foundation, to become a SCP of it's own, but it was declined by the Foundation, stating that Siren Head is it's own thing.

In Popular Culture

On April 30th, 2020, a film-creator and a Tik-Tok persona known as Alex Howard, created a video of Siren Head moving around in a background, while at the same time police and gun-fires can be heard. The video got popular very quickly, gaining over 20 million views in one week. The video escalated to the point of getting video-edited. The original background sound got replaces by numerous different songs and audio-clips, making it look like Siren Head is blasting music from it's horns. A good example is the video "Siren Head Gangnam Style" by Largetrap, where Siren Head is seen dancing and playing the infamous song Gangnam Style by PSY.


Its limbs are disproportionately long and thin, with arms almost as long as its entire body that ends in huge, bony hands. Where a human's head and neck would be is a thin pole of flesh with two sirens attached to them facing in opposite directions (hence its name), and several black wires snaking around its "neck" and into its upper shoulders, pressed against its abdomen. The speakers are fused to the neck by tendrils of skin and capable of swiveling around, much like the head of an owl. Some images depict Siren Head's speakers with toothy, lip-less human-like jaws and a long, retractable thin snake-like tongue, though Henderson has said that the teeth are only visible on a certain radio-frequency.

Hunting Tactics

  • Siren Head hunts by silently standing at Siren Head does to the victims once caught. And it’s hunting tactic can also be throwing shingles into the air Though multiple games were created, and to show off the fact Siren Head was in fact in the environment with the player, one or more corpses are normally found, which may show that Siren Head doesn't always kill for sustenance, even though none of the games were created by Trevor Henderson himself, nor proven to be fact over fiction. Other theories include eating them, or adding them to the roster of voices used by it.

It has brown mummified skin matching the pattern of rusty metal or tree bark, which it uses for camouflage. Siren Head is also very fast, while on 2 feet, its assumed maximum speed is around 24.3 MPH. While on all fours, its speed is assumed to be a maximum of around 258.2 MPH, making it much faster than the average car. Some people believe Siren Head to use echolocation like bats do to get around in the dark, as seen, Siren Head has no eyes.

Records of Siren Head

Recorded June 20th, 2010 in Chicago, Illinois. Multiple witnesses called in the CPD as a tornado siren in Willow Springs Woods started up unexpectedly at exactly midnight. When the CPD arrived at the scene, the sound had stopped and the source could not be located.

Recorded August 28th, 2018, in Weyer, Austria between 03:24 and 03:26. The sound originated from a forest on the outskirts of the town. When investigated in the afternoon, authorities found an empty tent and two wallets. Both wallets still had their contents in them, along with IDs: one belonging to Joachim Müller, and the other to Bruno Koffler. Both were residents of Weyer, and have since been reported missing.


July 16th, 1995 - Chad Gewecke is found wandering the woods of Tanyard Creek in North West Arkansas. He is admitted with minor injuries and when questioned, he claims his friends were taken or killed by “something huge striding through the trees” that mimicked their voices.

~ A quote describing what happened with a family after Siren Head came to them.[4]

The rash of disappearances had two commonalities: It was always people walking the side streets on their way home from work, from some social outing and it was always dark by the time people started wondering where they were. It was always past when the street lights come on.
