Sasquatch

The Sasquatch, also known as the Wendigo or Yeti, is a animalistic humanoid Monster kept in the Facility. Nobody bets on its release. It can be briefly seen in its Cube Prison and during the System Purge.

Physical Description and Attributes
A Sasquatch is typically a large humanoid with brown or blackish fur covering almost all of its body, with large hands and feet and its head and facial features larger than an average human's. This Sasquatch appears to be 7-8 feet in height, making it easier to spot but deadlier to encounter due to its potential strength. A Sasquatch's exact characteristics differ depending on local folklore and even from legend to legend, but all describe them as being incredibly fast, strong and stealthy, being able to evade human contact and sight with ease. How and when the Facility captured this Sasquatch is unknown, but they were lucky in doing so. Possibly it was simply gifted to the Organization by the Old Ones.

Appearances
The only time we get to see the Sasquatch during the film is briefly on a CCTV camera, just out of view. There he can be seen throwing a Facility worker around inside a locker room. Other than this appearance, the only time the Sasquatch can be seen up close is in behind the scenes footage or in the visual companion of the film.

Trivia

 * According to a Q&A with Drew Goddard, the item in the basement that would summon it is a jar of Eau de Sasquatch.

Inspiration
The monster is based on several different creatures. Various Native American legends and reported sightings are the basis of the Sasquatch, also commonly known as "Bigfoot". The creature is described as a large, bi-pedal creature with large footprints, an unusually offensive odor, and thick brown or black fur. It is considered a cryptid: an animal whose existence has not been verified and remains largely in doubt. No hard evidence of the Sasquatch exists, as DNA testing of hundreds of supposed samples have all been determined to be from known animals. The creature is the subject of an incredible number of hoaxes, perpetuating belief in popular culture of its actual existence. In Western culture, the Sasquatch has become a pop culture icon, often appearing in modern media, such as movies, cartoons, TV shows, commercials, comic books, merchandise and even some video games. Similar creatures are sometimes alleged to exist in swampy parts of Southern US as well.

The Yeti is a similar cryptid reported to exist in the Himalayan mountains, originally popularized in the west as The Abominable Snowman. It's appearance is largely similar to the Sasquatch, described as a large, upright walking "man-bear" with black or brown-red fur. Despite this, popular depiction in western media almost universally depicts the Yeti with white hair. Its actual existence is considered more likely than that of the Sasquatch, mostly owing to the isolation of its environment, although it is still largely considered either fictional or a species of bear.

The Wendigo is an amalgamation of a wide variety of creatures from Native American mythology. It is either an evil spirit of the winter, or a human possessed by such a spirit, driven by famine to consume human flesh and/or overwhelmed by greed. The majority of depictions have little in common with either the Sasquatch or Yeti. Most describe it as monstrous and gaunt, with a skeletal or bestial appearance. In some depictions the Wendigo takes on gigantic proportions, growing such that no matter how much it consumes it will always be famished. The legend has many parallels with legends of the Werewolf from Eastern Europe.

Many terror and spoof films use Sasquatch, the Yeti, and less commonly, the Wendigo as a stock monster. The creature and creatures similar to it have been featured in films such as Abominable, Bigfoot, The Legend of Boggy Creek, Ape Canyon, Night of the Demon, Curse of Bigfoot, Night of the Bloody Apes, Troll Hunter, Wendigo, Night Beasts, The Abominable Snowman (1957) and several others.
