The Cenobites are extra-dimensional beings who are mutilated and brainwashed into torturing humans for all eternity in the Labyrinth. All Cenobites were once human, with the exception of Angelique, the daughter of the demon god Leviathan.
The Cenobites can only be summoned upon the solving of one of the Lemarchand's Boxes, a type of puzzle box that promises pleasures.
When a person solves one of the many boxes (Carborro, the Lament Configuration, etc), a small group of Cenobites arrives. If Leviathan, god of Hell, believes the person is worthy to become a Cenobite, they are taken to Hell to be made a Cenobite. If the person is not deemed worthy, the human will most likely be forced into Hell, where they will spend all eternity in Hell's prison, or be destroyed on the spot.
Despite being Leviathan's soldiers, they are not drones since some of them are capable of going rogue and even questioning Leviathan's authority. The prime example is the group of rebelling Cenobites led by Alastor or Doomdayers when he rallies his fellow Cenobites in questioning Leviathan's competency. However, these rebellions are short-lived since almost all of them are being killed by their fellow Cenobites.
The Cenobites are immune to any kind of mortal weapon or attack used against them, unless the weapon is used by another Cenobite. The prime example is if humans try to shoot a Cenobite with a gun they are unfazed by the attack but the assault rifle used by the Cenobite Atkins can kill a Cenobite easily, in the case of Doomdayer. So far the only beings that can injure or kill a cenobite are the Cenobites themselves, supernatural creatures or a high tier deity such as Leviathan's sister or Leviathan, himself, in case any cenobites upset him. In the movie version, when a Cenobite dies, they return to their human form.
Humans can actually kill and vanquish Cenobites if they possess holy, magical weapons or an artifact like in the case of Dr Paul Merchant who permanently kills Pinhead and all his cenobite cohorts using the Elysium Configuration.
