The Suffocators are monsters not listed on the whiteboard.
Physical Description & AttributesEdit
The Suffocator appears as a large, muscular, bearded human male with no shirt and a crude cowl made from a torn plastic back strapped to his neck via a leather collar. He wields a simple plastic bag with which he asphyxiates his victims.
They are seen during the climax of the film on the lower left corner of a security monitor, suffocating a person with a plastic bag.
It is unknown what summons them.
One of the few cases of original creations for the film, but clearly inspired from methodical serial killers.They were named in a question and answer session by the movie's director/co-writer Drew Goddard on Reddit, in which he states that they are the monsters that terrify him the most and they made him uncomfortable on set.
Considering the movie's criticism of the "torture porn" and "snuff film" aspects of modern horror, he may also be a reference to the video game Manhunt where your character is literally forced into making a violence-based snuff film. One of his major kill moves is yanking a plastic bag over another person's head to smother them.
