→Creatures and denizens
After Crowley is betrayed by his demons and deposed as ruler by Lucifer, he agreed to help the Winchesters trap Lucifer in [[Apocalypse World]], in addition to agreeing to close the Gates of Hell forever, having grown tired being ruler and dealing with demons. Crowley was unable to make good on his promise, due to sacrificing himself to close the rift between universes to trap Lucifer. In Crowley's absence, at least one demon, [[Kipling]], attempted to fill the power vacuum left in Crowley's wake. His attempt to take over Hell, saw Kipling try and strike a deal with Sam Winchester, along the same lines as they had with Crowley. After Sam rejected Kipling's offer, and killed him, Sam would declare that, "There will be no new King of Hell. Not today. Not ever. And if anybody wants the job, you can come through me." A threat demons seemed to take to heart, as according to Nick the demons have kept track of where the Winchester family is at all times out of fear in order to keep far away. [[Belphegor]] later attempts to use [[Lilith's Crook]] to gain power in Hell, but is [[smiting|smote]] by Castiel, preventing this plan. According to [[Ardat]], Belphegor spent centuries waiting for his chance as all of the other leaders were killed.
denizens===Human [[soul]]s can get sent to Hell after making [[Deals and Pacts|deals]] with [[crossroads demon]]s or other demons with the authority to make deals such as [[Azazel]] and [[Lilith]]. [[Hellhound]]s capture then kill the person when their their time is up. Once in Hell, a soul will be tortured for centuries until the last vestiges of their humanity are burned away, creating new demons to continue the cycle of torture. The length of time it takes for a human to become a demon is unknown, as John Winchester spent a century being tortured, and was able to escape Hell in his human form. Like entry into Heaven, the criteria for a person being damned to Hell beyond selling one's soul is unknown. Human souls can remain in Hell for centuries before turning into demons. Souls that have escaped Hell, can appear as [[Hell Ghosts|skeletal apparitions]] that can manifest and retain their human appearance on earth.

Once a human soul has had it's humanity burned away, their once human form gives way to a more mangled and horrific visage turning them into demons. The longer a demon resides in Hell the stronger they can become, making escape somewhat more easier. Once Crowley took over Hell, access to to the earthly plane was made more difficult, as he would only allow certain demons, whom he knew he could control topside.
Hell is also home to various demonic entities:
