Siren Head, also formatted as "Sirenhead", (Sirenmonstrus sirenmonstrus) is one of the main antagonists of the Trevor Henderson mythos. It is a hostile cryptid and urban legend created by the Canadian horror artist Trevor Henderson.

Biology[]

Siren Head is a 40-foot-tall humanoid creature with a heavily emaciated, near-skeletal frame covered in dried, mummified flesh the color of rusty metal. Its limbs are disproportionately long and thin, with its arms as long as its legs, ending in huge, bony hands. Where its head and neck would be, instead a thin metal pole with a pair of acoustic sirens attached to it (hence the name) stretches up from between its shoulders, with black wires coiling around the pole and connecting the sirens to its upper torso. These speakers are the only metal parts of its body, fused to the neck by tendrils of skin, and capable of swiveling completely around, similar to an owl's head. Some images depict Siren Head's speakers bearing toothy, lip-less jaws and long, retractable tongues.

Behavior[]

Siren Head is a very aggressive, monstrous, and skilled predator, which makes it very dangerous. It seems to have some degree of intelligence due to using tactics such as camouflaging within forests and mimicking sounds like voices to hide from and lure its prey. Other than that, nothing much else is known about Siren Head’s way of thinking, though unconfirmed theories suggest it is the last of its kind and so might have a strong will to survive. It is possible that the entity developed its camouflage abilities in order to hide from even more dangerous beings, though again this is not confirmed.

Siren Head is not above fooling people with their friends' voices. One sighting suggests that it also blocks out the screams of its devoured victims with other sounds, in order to prevent anyone from coming to the victim's aid. Thus, while weapons are not known to work on Siren Head, its need to conceal its attacks and generally elusive behavior imply that there may be some way of harming it, or at least interrupting its activity. Alternatively, this may be done to ensure a successful hunt by confusing and disorienting the prey, or it might be simple cruelty. Siren Head does not always consume its victims as seen in the Siren Head video game, meaning it is possible that the entity kills for reasons other than obtaining sustenance.

One of the later possible sightings of Siren Head includes a news story describing the aftermath of an unusual, never-before-seen killing tactic. For unknown reasons, Siren Head chose to kill many of the people in a town/neighborhood by bursting their eardrums and soft tissues. It is not known whether Siren Head produces a specific sound to cause such an effect, or if it simply made noises that were loud enough to do so. Many of the residents were left behind and not taken by Siren Head, suggesting that Siren Head has started killing large groups of humans for no further purpose.

This is a departure from its previous behavior, as it normally only stalks and kills individuals or small groups. It is possible that this multi-headed version of Siren Head is a subspecies, or simply a design update, though Trevor has not confirmed either theory.
