Knights of Hell

"Knights of Hell are hand-picked by Lucifer himself. They are of the first-fallen, first-born demons."

- Henry A Knight of Hell is a unique breed of demon directly created by Lucifer. As such, Knights are among the oldest and most powerful of their kind. The order of Knights was built by Cain, himself a Knight. Their exact rank in the hierarchy of Hell is not stated; however, they appear to be figures of awe among most demons, and refuse to obey demons they consider inferior to them. Cain eventually slaughtered all Knights but Abaddon, though the extermination was originally attributed to the archangels. Until Abaddon appeared in the year 2013, it was believed that all the Knights were dead.

History
At some point in the past before the archangels purged them, the Knights were trained by a demon named Cain, who was also known as the Father of Murder. Some time after that, Knights of Hell were then exterminated by the father of murder himself, Cain. At least one Knight—Abaddon—managed to escape this purge. That this extermination had become a "legend" by 1958 indicates that the Knights of Hell had either not been active on Earth or they kept their presence on Earth secret from even the Men of Letters long enough for them to all be assumed dead. This was proven untrue when in 1958, Abaddon killed Father Max Thompson to put a stop to his attempts at "curing" demons, slaughtered the Men of Letters, and travelled into the year 2013, where she seeks to lay claim to rulership of Hell.

Characteristics
As a type of demon, Knights of Hell are evil spiritual entities that were created from human souls being stripped of their humanity. As a result of having been made by Lucifer himself, Knights of Hell are "very pure" and "very strong" demons. They are called the first demons, making them among the oldest of their kind; this would mean that they were made shortly after the creation of Lilith herself (the very first demon).

The King of Hell outranks the Knights of Hell and they are expected to serve him, but they may stage a coup if they disapprove of the current King. The Knights of Hell are higher-ranked than common demons and most likely Crossroad Demons. They usually command great respect from their fellow demons and have their own subordinates: Abaddon had at least one demon who served her in the past, and she currently has assembled a group of demons willing to turn on Crowley and help her become Queen of Hell. Larry Ganem called Abaddon a "hired gun," which would indicate that they may be willing to work for other parties for a price. Alternatively it could mean they are simply subservial to higher demons.

Appearance
What a Knight of Hell looks like in its true form is unknown, but given descriptions of other demons' true faces, it is likely grotesque. On Earth, its true form manifests as a cloud of black smoke. A Knight of Hell may possess a human in order to interact with the physical world and its inhabitants. Most of the time, its vessel will not look any different than it how it did before she was possessed, but her eyes may change colors on occasion (such as when the Knight of Hell is extremely angry or wanting to intimidate its enemies) to reveal her possession; for example, Abaddon has displayed completely black eyes typical of most demons. Certain other beings, such as other demons, can perceive a Knight of Hell's true form even when it is envesseled, but ordinary humans are limited in the sense that they can only perceive its vessel or, if the Knight is not in a vessel, its smoke form.

Powers and abilities
A Knight of Hell is a particularly strong type of demon; in fact, in "Sacrifice", Crowley indicated that a single Knight of Hell is more dangerous than a group of ordinary demons. A Knight of Hell has powers that are rare among other demons and has fewer weaknesses than most demons do.


 * Possession - Knights of Hell can go into human bodies and take control of them, using them as their vessels on Earth. Notably, they can be inside two humans at once by inserting a portion of their essences into a second human while the majority of the Knights' essences remain in control of the first. However, each time this happened, it only took place for several moments before the Knight in question exited the second human and returned to her original host, leaving it unclear if Knights of Hell can possess two humans at once over a long period of time or if they can only perform split possessions temporarily.
 * Biokinesis - A Knight of Hell is capable of making humans bleed profusely from their eyes, resulting in permanent blindness.
 * Immunity - Unlike most demons, Knights of Hell are immune to exorcism rites, churches, and the Demon-killing knife (though the knife does cause them pain and slow them down temporarily). They are also more resilent to Holy Fire than standard demons.
 * Super strength - Knights of Hell have inhuman physical strength which allows them to break a man's neck with a blow or quickly and brutally thrust a hand into his abdomen, wounding him enough to kill him.
 * Telekinesis - Knights of Hell can move objects and people with their minds. They can use this power to throw adults through only a hand gesture.
 * Invulnerability - Knights of Hell are little affected by damage dealt to their vessels, even injuries as severe as being stabbed, gunshot wounds, decapitation, and dismemberment. They may not be as tuned in to physical sensations as humans are, as Abaddon did not even notice that her hands were missing until Dean pointed it out to her.
 * Telepathy - By blowing a portion of its essence into a human, a Knight of Hell has the ability to access that human's memories to see and hear what that human had seen and heard. The Knight appears to be able to instantly identify and access specific memories it wants to see, rather than having to shift through all of a human's memories.
 * Immortality - Having been created by Lucifer prior to his imprisonment in his cage, Knights of Hell are thousands of years old. They will not die of old age; unless killed, they will live on indefinitely.
 * Weather manipulation - A Knight of Hell is capable of creating or atleast causing weather phenomena; an infuriated Abaddon caused thunder and lightning by screaming.
 * Super stamina - Knights of Hell do not require food, water, or sleep to maintain themselves.
 * Terrakinesis - A Knight of Hell can cause ground tremors. Abaddon used this power to split the ground of a church before she had even physically arrived there.
 * Flight - When outside of their vessels, Knights of Hell can fly or hover above the ground like anyother demon.
 * Tactile Exorcism - A Knight of Hell can expel another demon from its vessel and send it back to Hell simply by grabbing the demon's vessel by the neck.
 * Teleportation - Knights of Hell can disappear from one location and reappear in another instantaneously.

Vulnerabilities
A Knight of Hell is subject to some of the weaknesses that most demons have.


 * Demon-killing knife - Although the knife cannot kill a Knight of Hell, it can temporarily incapacitate one, causing Abaddon enough pain to bring her to her knees.
 * The First Blade - This was the weapon the archangels used to destroy Knights of Hell.
 * Archangels - It was claimed that all Knights of Hell had been killed by archangels; although this was proven untrue as Abaddon managed to escape the purge. When Abaddon learned that Sam and Dean had brought along an angel as back-up, she quickly fled the area, which implies that battling even a common angel is a challenge for Knights.
 * Devil's trap - A Knight of Hell can be stripped of its powers if placed in a devil's trap. The trap has much the same effect if it is placed on or inside of the Knight's vessel instead, with the additional effect of severely restricting the Knight's ability to move.
 * Holy fire - A Knight of Hell finds holy fire extremely painful, to the point that Abaddon abandoned her vessel and fled when it became engulfed in holy fire. However, holy fire does not kill Knights and they are more resistant to it than common demons are, as they retain the ability to move their vessels' bodies when it is burning with holy fire, unlike other demons.
 * Holy Water - Contact with holy water causes a Knight of Hell to react as if burned. It was used to great effect on Abaddon, causing her to stagger backward and cover her face in pain for a short period of time without attacking her targets.
 * Angel Blade - It is implied that an angel blade can at least hurt, if not kill, a Knight of Hell, given that Abaddon took care to disarm Dean of his when he confronted her with it.

Trivia

 * Abaddon is the only named Knight of Hell. Additionally, Dean suggested in "As Time Goes By" that she is the last of her kind.
 * Fans have theorized that certain powerful demons who have appeared on the show, such as Alastair and Azazel were Knights of Hell who were not identified as such. However, no demon other than Abaddon has been confirmed as a Knight, leaving the possible identities of other Knights speculation.
