Siren Head was created by Trevor Henderson, who is known for making various bizarre creatures over the internet. His other creations include Cartoon Cat, the Country Road Creature, the Bridge Worms, the Man with the Upside-Down Face, the Smile Room, the Good Boy, the Lamb, the Man in the Red Room, the Fetid King, the Giants and Long Horse.
The only parts of Siren Head that are man-made are its sirens and wires, which are fused to its dry and mummified skin.
Although it commonly does produce sounds mentioned previously, Siren Head can also remain silent at will in order to avoid detection.
When asleep, Siren Head produces white noise from its speakers.
According to Henderson, Siren Head would be unaffected by an EMP, as it is mostly organic.
On Twitter, Henderson posted an artwork of Siren Head, calling it the “patron saint of going missing without a trace, of creeping dread, of bad things, coming.” Interestingly, the artwork features an iteration of Siren Head with an additional third smaller siren on its neck as opposed to the usual two-headed design. This might mean that Siren Head was redesigned.
Siren Head was proposed to the SCP Foundation site as the non-canon SCP-6789, but it got removed by the Foundation, and they stated that Siren Head is not an SCP. Any source implying Siren Head to be a SCP is false, since Henderson has stated that he wishes to keep Siren Head as his own separate work.
SCP-5987 is named “Sirenhead”, but is about the figurehead of a French privateer brig. The Captain of the aforementioned ship was titled “6789-AH,” an obvious reference to SCP-6789.
Henderson has confirmed that Siren Head and Long Horse are aware of one another, possibly being enemies due to their different views on humanity.
Henderson confirmed that Siren Head is the only one of its species when he responded to an ask on Tumblr about his creations possibly being part of a species; he name drops Siren Head, Long Horse, Bonesworth and Mr. Mascot as a few of the many monsters that are the only one of their kind.
Siren Head’s movement is nearly completely silent.
Siren Head appears to be one of the largest of Trevor Henderson’s creations, both figuratively and literally, being one of Trevor Henderson’s most popular creations and it itself being around 40 feet tall.
Siren Head and by extension, the rest of Trevor Henderson’s art, has recently gained much more fame due to videos created by YouTubers, such as: PewDiePie, Markiplier, JackSepticEye, CoryxKenshin, LaurenzSide, 8-BitRyan, and many others playing the Siren Head game and exploring more of the lore and other creatures created by Henderson.
Henderson has responded to an ask on Twitter on how Siren Head could resemble tech from the 90’s or 2000’s in ancient times. Interestingly, he responded with “What we’re seeing might be the most recent form, or maybe a slightly outdated form, of something that consistently changes. Maybe our eyes just show us the closest approximation to what’s actually there and this ‘fits’.” This could possibly mean that Siren Head changes itself depending on the era it is in in order to blend in more easily, or that what we see is not its real form, but the closest thing the human mind can associate with it.
Siren Head is said to be some sort of “ambassador/emissary/hype man for…something else from somewhere else.” What this something else is is currently unknown.
However, it might mean that Siren Head is a mere pawn of something even more powerful.
Henderson has stated Siren Head does not actually need eyes, ears, a nose, or the ability to feel vibrations to be able to find prey due to its supernatural nature.
Trevor Henderson confirmed himself that Siren Head is not of this reality, with the fact that it is not just an extraterrestial from another dimension, but plausibly multiple beings that share a collectivist consciousness.
A group of Siren Heads is called a static.
In 2018, Henderson revealed that a Siren Head action figure is being made for sale, created by toy maker and designer Jeff D’Ottavio. It’s believed that the action figures are still being prepared, or the project was dropped. Others have been creating their own versions of the action figure, publishing their work on YouTube and other social platforms.
Henderson implied that Siren Head and Cartoon Cat are enemies of Long Horse and the Lamb. Additionally, he said that Siren Head and Cartoon Cat come from “the void” in the same post.
Trevor Henderson was asked if the “void” was a concrete concept in the mythos or if it’s just a way of him the creatures come from the darkness ideologically, Henderson confirmed that the latter is the case.
Siren Head is Henderson’s favorite creature.
On the reference above, Henderson said that Siren Head once had a purpose.
