"An endless array of elevators. Monsters in every single one. It's the CostCo of death." - Script's description of the cube prison.

Monsters are a network of various creatures, which include man-made abominations, legendary beings, and supernatural entities.

Many of the supernatural creatures provided to the Facility are for the purpose of murdering the five sacrifices in the Ritual. For each monster, there is a corresponding item that can be used to summon it.

Appearance and Characteristics

The four major types of such creatures are:

  • Supernatural - This type of monster is for those of the supernatural category.
  • Psychopaths - This type of monster is for those who are psychopaths.
  • Folkloric Creatures - This type of monster is for those of folklore.
  • Common Phobias - This type of monster is for the representations of the different phobias.

Minor types include:

  • Undead Humans - This type of monster is for humans that have been brought back to life in an undead state.
  • Demons - This type of monster is for demonic creatures.
  • Extraterrestrials - This type of monster is for those that aren't of Earth.
  • Giant Animals - This type of monster is for animals that are larger than normal.

Many monsters can have more than one categorizations like Kevin (psychopath/common phobia), The Doctors (common phobias/undead humans) and Reavers (undead humans/psychopaths). While most monsters correspond to certain tropes, some are more specific, if not original, like Jack O'Lantern, Sugarplum Fairy, and Dragonbat.

As to fill multiple horror conventions, each of the monster's appearances differ between them. It is clear that every monster is kept in thousands of identical cube prisons roughly the size of the elevator, so the monsters (each) would be small enough to fit inside them, despite some of them appearing too big on the outside (like the KrakenGiant, and the Angry Molesting Tree).

Their behavior differs between them, some of them acting like savage animals (i.e. Man in Transparent Tarp) while the others remain calm and collected (i.e. Ku Klux Klan), as shown when some of them tried find a way out of their cubes while others calmly waited to be let out. 

While their modes of behavior may differ between them, they all have a single, solitary goal in mind: kill every human being they see. They lack an actual will of their own, completely ignoring their situation, the surroundings and each other (unless they are monsters that operate in groups like The Dolls, The Scarecrow Folk, and Mutants) simply to perform their dark task. Despite their inherent violent and evil nature, they are never seen in conflict with each other, as seen when the Dragon Bat ignores a helpless human in front of it, because another monster was already advancing on him.

Their methods of killing range from suffocation, stabbing, burning, tearing, beating to death, slow torture and biting. While the book describes what they do as simply feeding themselves, they may not need to survive in mortal ways, those who eat simply eating for the sake of it (like the Giant Snake and the Zombies). Whether or not they can die varies, as the Clown was shot three times in the chest to no visible effect while Marty was able to kill a Mutant in Hospital Gown with a single headshot.

Many fans theorize that the monsters are actually the pets of the Ancient Ones, and are wanting to be set free to re-unite with their owners. They also believe that some of the monsters had helped out in getting Dana and Marty into the Facility. Though it is also possible that all of the surviving monsters were killed when one of the released Ancient Ones destroyed the Facility.
