It is similar to a spider, but with mannequin heads and legs, with the heads serving as its eyes. Behind the mannequin masks, the monster has an appearance similar to that of the Split Worm from Silent Hill 3, but with many more teeth in addition to a smaller, tongue-like mouth that protrudes from the center and grabs its prey.
In addition to resembling the Split Worm, the Mannequin Monster also resembles the monster Scarlet from Silent Hill: Homecoming, due to both having a doll-like appearance and gangly body. The Mannequin Monster also walks around on all fours, much like Scarlet's second form.
Silent Hill: Revelation
Heather Mason encounters the Mannequin Monster when she accidentally stumbles into its lair while running from the Otherworld in Silent Hill. She finds a girl who is becoming a mannequin, but is unable to help her before the transformation is complete. Heather then frees Suki, a young woman who is trapped in one of the Mannequin Monster's spiderwebs.
The monster appears and caresses the breasts of the new mannequin woman before ripping off its head and using it as one of its own. It then chases Heather and Suki, who disappear into a vent, but before Suki can get far into the vent, the monster grabs and presumably kills her.
In the black-and-white credit sequence, the Mannequin Monster is seen assaulting a group of Dark Nurses.
The Mannequin Monster is likely a reference to the many identities of Alessa Gillespie, one of which is Heather Mason. It may also refer to Heather's constant changing of names as she moves from town to town to avoid a fanatical religious cult. Thus, the Mannequin Monster may be the result of Heather's built up frustration due to always changing identities. This is again referenced when the Mannequin Monster's head opens vertically in a similar fashion to the Split Worm and Double Head from the game. This could relate to how identity can be split in half, or may even symbolize a dual nature, as is the case with Heather and Dark Alessa. It may even symbolize hatred and spite, as the Mannequin Monster's expressionless face reveals itself to contain something more hostile and ugly within, which would tie into the function of the Seal of Metatron in the film, revealing "the true nature of things", or Heather's "true nature" as Alessa.
The Mannequin Monster likely draws inspiration from the Silent Hill 3 game, in which Heather Mason enters a storeroom of mannequins and comments that she feels as if they are watching her, until one of them screams and has its head decapitated. Mannequins can be seen as a symbolism for likeness, as they mimic the form of the human body, posing as if they are real people showing off their clothing and fashion with pride. Female mannequins are often tall, graceful, flawless, and could symbolize how teenage girls often find themselves trying to strive for these ideals. Like the game, the mannequins in the storeroom are completely naked. This may relate to the student who mocked Heather's outfit at her school, acting cold to her as if she only cares about the exteriors of people (in this case, clothing). Even though mannequins mimic real humans, they are cold, hard, lifeless, plastic shells and are nothing more than mere objects to be put on display. This theory is shown to be true in the original version of Revelation's script, which shows that the girl lying on the table is the same teenage girl who mocked Heather about her clothes earlier that day. However, this version of the story only occurs in the script, and the girl seen in the final film is a different character, as well as having Suki added to the scene.
A young woman is seen transforming into a mannequin, her flesh and organs becoming plastic, and the monster decapitates it to adds to its collection of heads. This could symbolize Heather's fear of becoming a "mannequin" of sorts. With every mannequin head decapitated, the Mannequin Monster seems to increases in size and power. If this is the case, the disturbing idea of the mannequin being composed entirely of real people who were transformed into mannequins arises.
The Mannequin Monster also seems to have a tendency to target and attack women almost exclusively, as every single mannequin in its lair is female. This could serve to represent Heather's feelings of vulnerability in finding herself alone in Silent Hill, without her father to protect her. The Mannequin Monster can be seen attacking Dark Nurses in the ending credits of the film. This further accentuates its preference for female victims.
