Siren Head is primarily found in the woods, similarly to Slender Man, where it will release sounds out of the sirens atop its head in order to lure victims into its trap, where it will ultimately kill and eat the victims it is successful in luring. Henderson later started making more and more images of Siren Head, expanding on the creature's story and the disappearances of numerous victims all over the world. The first photo of Siren Head to ever exist was an image featuring Siren Head standing still at a graveyard. Trevor's inspiration for Siren Head's creation was the now very known creepypasta villain known as Slender Man. Siren Head was created back in 2018, by the Canadian designer, artist, and comic maker known as Trevor Henderson. Many fan-made video games featuring Siren Head exist, though they are not made by Henderson himself. Siren Head has become extremely popular over the recent years after well-known YouTubers such as CoryxKenshin, Markiplier, PewDiePie, and Jacksepticeye made their own videos about the creature and its various media and unofficial video games. It uses its telephone pole-like appearance to hunt humans.

Siren Head was described by Henderson as the 'tatic physical form of unfathomable supernatural entity.' Siren Head is approximately 40 feet tall, can see without having any eyes, doesn't eat, despite having organic teeth, is rarely seen in areas with large populations, and is usually stationary but can move very quickly. Siren Head is a humanoid monster created in 2018 by the Canadian artist respectfully known as Trevor Henderson.
