Death is one of the [[Four Horsemen of the Apocalypse]]. Referred to in the Book of Revelation as the Pale Horseman, he appears the original Death appeared to be the most powerful and eldest of the four, older than [[Famine]], [[War]], and [[Pestilence]]. According to him, he is the only being in existence that will persist through the end of time. According to Death neither he nor [[God]] can remember which of them is older. Since [[Amara]], God's sister, claims claimed that she doesndidn't know who Death iswas, and vice versa, it proves that God is older than the pale horseman.<ref name="eleven01">[[11.01 Out of the Darkness, Into the Fire]]</ref> Death also believes believed at the end of time, God himself will die, and he will then reap God.<ref name="five21">[[5.21 Two Minutes to Midnight]]</ref>

After the defeat of Lucifer, Death returns returned his attention to maintaining the natural order.<ref name="six11">[[6.11 Appointment in Samarra]]</ref> In spite of his own reservations about resurrecting the dead, he retrieves retrieved [[Sam]]'s soul from [[Lucifer's Cage]] and returns returned it to him so that the Winchesters will could continue to investigate a greater threat against the balance of life and death.<ref name="six11" />

As a very powerful being In 2017, it's revealed that existed before time began, he has extensive knowledge of the universe and is aware of the threats and actions regarding [[Purgatoryreaper]]. After [[CastielBillie]] takes on had taken Death's place due to a rule stating that the role next reaper to die after an incarnation of God, Dean binds Death in hopes he will kill Castiel for themis killed becomes Death themselves. HoweverBillie works with the Winchesters from 2019 to 2020 to take down [[God]], Castiel breaks his binding before he can but it's revealed that her true plan is to take power as the new God once God and leaves[[the Darkness]] are gone. While Death is not happy with their actionsMortally wounded by Dean, he agrees Billie attempts to help them put kill him as her last act but is absorbed into [[the Empty]] by the souls back in Purgatory[[Cosmic Entity]], mostly because he's annoyed with how arrogant Castiel has becomewhom she had also double-crossed.

After the [[Mark of Cain]] causes him to get [[Rudy|another hunter]] killed, Dean summons Death in hopes Death can kill him. However, the Mark's power is such that even Death can't do that and he explains about [[the Darkness]] and the consequences of removing the Mark. He offers to send Dean somewhere far away where he is no threat, but demands Sam's life in exchange. While Dean initially agrees, he instead turns Death's [[Death's Scythe|own scythe]] on him, killing Death who crumbles to dust. In 2017, it's revealed that the [[reaper]] [[Billie]] has taken Death's place due to a rule stating that the next reaper to die after an incarnation of Death is killed becomes Death themselves. Billie works with the Winchesters from 2019 to 2020 to take down [[God]], but it's revealed that her true plan is to take power as the new God once God and [[the Darkness]] are gone. Mortally wounded by Dean, Billie attempts to kill him as her last act but is absorbed into [[the Empty]] by the [[Cosmic Entity]], whom she had also double-crossed. A third incarnation of Death is was created soon after Billie is taken to the Empty. In order to read His [[Chuck's Death Book|death book]], Chuck has Lucifer create a new Death by killing a reaper named Betty, whom he eventually kills again as soon as she opens the book, but before she can reveal its contents, leaving no current incarnation of Death.

The third Death, [[Betty]], though short-lived, shows showed a similar lack of patience for the Winchesters.

Death owns a scythe purportedly capable of reaping any being, including [[angels]], [[demons]], and [[reaper]]s.<ref name="four15">[[4.15 Death Takes a Holiday]]</ref><ref name="five21" /> It is the only known weapon capable of killing Death himself. When a new Death is born after a previous incarnation has died, they are gifted with a new scythe upon their ascension.

Billie explains that when she became the new Death, she was introduced to the big picture as well as inheriting Death's collective knowledge and Death's Library. In the library, everyone has a book detailing how they might die, including [[God]]. Dean remembers when Death told him that he would reap God in the end back when they met in Chicago during the [[Apocalypse]] ten years ago. She explains that when [[Chuck]] created the world, He integrated Himself into the framework of the multiversal quantum construct to be able to create [[alternate universes]] and ensure that the Winchesters' world kept operating in His extended absence. She explains that [[Team Free Will 2.0]] Sam and Dean are the ones who will herald God's ultimate demiseas the messengers of God's destruction. ===[[15.13 Destiny's Child]]===After Sam and Dean come across [[Sam and Dean Winchester (HunterCorp)|doubles]] standing in front of a [[Portals|rift]] in the Bunker, Billie explains that they were most likely fleeing their universe as Chuck has been destroying all the worlds he has created. Believing that Chuck is close to returning, Billie gives Jack his next ritual, which involves locating something known as [[the Occultum]]. When Sam presses her on where they can find it, Billie simply tells them she doesn't know as it has been hidden for centuries, only telling them it is sacred and potent. Before departing, she warns everyone to be careful and vigilant and not to do anything stupid, as if Chuck gets wind all their work would be for nothing. ===[[15.18 Despair]]=== ===[[15.19 Inherit the Earth]]===
