The Scorpion Stinger Woman is a Monster from the novelization of the film. She is mentioned in the 'Elevator Scene' part of the book.
Physical Description and Attributes[]
As her name implies, the Scorpion Stinger Woman is a normal-looking, human woman but has been mutated or fused with the DNA of a scorpion and now has a scorpion's tail and stinger. How this happened to the woman is unknown, but its likely she was some sort of scientific experiment gone wrong, and now she is kept in the Facility either because she is being studied or is hostile to humans.
Inspiration[]
It's hard to say what inspired it, but the horror\sci-fi film series, Species, has a monster very similar as it is a monster that takes the form of a woman who kills and absorbs it's victims with scorpion appendages including a tail. This monster may also be a visual pun on the term "scorpion woman" which is a term meaning to describe a snappy or unpleasant woman.
