Monsters (The Cabin in the Woods)

The Monsters are a group of numerous different species of supernatural creatures supposedly provided within the confines of the Facility by the Ancient Ones for the Organization to use in order to murder the five sacrifices for their ritual. Each creature has a monster item that is used to "summon" them. They serve as the tertiary antagonists in the 2012 American horror comedy film The Cabin in the Woods.

Trivia

 * Most of the monsters that appeared in the movie are reference to many numerous horror movie characters and icons, as well as the mythological ones. The most notable example would be Fornicus (who is a reference to Pinhead), The Dolls (who are a reference to The Strangers), The Buckner Family (who are a reference to the Sawyers from Texas Chainsaw Massacre, having an aspect of undead immortality like Jason Voorhees'), the American Slow-Walking Creepy Girl (likely a reference to Alma Wade), & the Yurei (who is either a reference to Sadako/Samara or Kayako).
 * The monsters also bear many similarities with the creatures from the SCP Foundation. The most notable would be SCP-049 & SCP-993.
 * Two of the monsters are played by Richard Cetone, notably the werewolf & the merman.
 * During an interview with Kristen Connolly who was Dana Polk's actress before the movie's release, she briefly mentions that they are supposed to be attacked by a group of Pterodactyls during the System Purge scene. In the movie, the Dragonbat, a giant bat monster in the movie attacked them instead. It is currently believed that the Pterodactyls are the earlier incarnations of the Dragonbat.
 * A unicorn is spotted as one of the few known monsters, during the System Purge where it is seen killing a worker of the Organization. Many fans and viewers suggest this to be a joke.
 * It is current unknown what inspired this unicorn to appear since it is unusual for a unicorn to appear in a horror movie. However, there are a lot of theories:
 * It may have been inspired by the mythological portrayal of the Assyrians to unicorns as symbol of evil.
 * It may have been possibly inspired by the cover of the book Narnia: The Last Battle, which features a unicorn with blood covered on its horn.
 * It may have been possibly inspired by the horror-themed internet parodies of My Little Pony such as Rainbow Factory, Friendship is Murder & Cupcakes.
 * Boomer zombie, Witch zombie, Hunter zombie & Tank zombie from Left 4 Dead made cameos as one of the monsters. The directors of the movie originally planned to released a DLC exclusive of Cabin in the Woods cabin and facility for Left 4 Dead. This idea was scrapped due to the fact that the company producing the DLC went bankrupt.
