Knights of Hell
The Knights of Hell are demons who were handpicked by Lucifer from among the first fallen humans to be made into demons. They were rumored to have all been killed by the archangels, though one survived - Abaddon. Its eventually revealed that Cain actually killed them in revenge for them kidnapping and killing his wife, but left Abaddon alone as his wife made him promise to stop his ways. Abaddon was sent by parties unknown to kill the Men of Letters in 1958. After she travels through time in pursuit of Henry Winchester and the box to 2013, she is trapped inside her meatsuit and buried.[1]
Abaddon escapes after Sam and Dean exhume her body, and try to use her for the third Trial to close the Gates of Hell.[2] She later tries to kill Crowley so she can take over Hell, but Sam douses her in holy oil burning her meatsuit, and forcing her to vacate the body.[3] She later gets her meatsuit restored and starts a crusade to take over Hell and Earth.[4] Dean and Crowley are currently working on locating the First Blade, the only thing that can kill Abaddon.
Knights of Hell appear have the powers of normal demons, as well as abilities and powers far beyond that of any other demon seen so far.
