Changes

An angel is a divine being created by [[God]], able to [[manifest]] physically on earth by occupying a [[vessel]]. During God's long absence, angels became the caretakers and rulers of [[Heaven]]. The [[Nephilim]] [[Jack Kline]] has shown the ability to forge new angels from the souls of humans.

Among the hierarchy is [[Naomi]] who holds an unknown rank, but works in intelligence and is clearly very high-ranking. Metatron reveals that she is a major player in fighting over for the right to rule Heaven. After Metatron expelled all angels from Heaven to Earth using a spell, he declared himself to be the sole ruler of Heaven. On Earth, many angel factions formed led by [[Bartholomew]], [[Malachi]], [[Tyrus]] and [[Rebecca]]. Both Bartholomew and Malachi wanted to unite all of the angels and retake Heaven under their leadership and Rebecca and her faction wanted to coexist with humans. Bartholomew killed Rebecca and wiped out her faction while Castiel killed Bartholomew in self-defense. Currently another faction is forming under Castiel's leadership that wants there to be no more unnecessary bloodshed between angels. Castiel's faction comes into conflict with one led by [[Metatron]] and [[Gadreel]] who kill anyone who refuses to join them including Malachi. Metatron eventually manages to unite all the angels under his command and attains God-like power with the help of the [[Tablets|angel tablet]], but with the help of Gadreel, Sam, Dean and Castiel destroy Metatron's power and overthrow him. Metatron is locked in Heaven's dungeon and all the angels look to Castiel for leadership. However, Castiel declines the leadership and a quorum of angels is formed to run Heaven by committee, of which included [[Hannah]] in a high ranking position.<ref name="nine14" /><ref name="nine21">[[9.21 King of the Damned]]</ref><ref name="nine23">[[9.23 Do You Believe in Miracles?]]</ref> According to Metatron, under Hannah's leadership, Heaven is run better than it has since God "cut the ribbon on the pearly gates."<ref name="ten18">[[10.18 Book of the Damned]]</ref> After Hannah's death, Heaven's leadership is indicated to have fallen apart.<ref name="eleven03">[[11.03 The Bad Seed]]</ref> A lower-ranking angel takes command to fight [[Amara]], but is killed in a failed attack on her.<ref name="eleven09">[[11.09 O Brother, Where Art Thou?]]</ref> [[Lucifer]] subsequently takes control for a short time before being captured by Amara.<ref name="eleven18">[[11.18 Hell's Angel]]</ref> [[Joshua]] is known to have taken up a leadership role during the [[Nephilim]] crisis and was stated to have the power to pardon Castiel,<ref name="twelve15">[[12.15 Somewhere Between Heaven and Hell]]</ref> but he was killed by the [[Prince of Hell]] [[Dagon]].<ref name="twelve19">[[12.19 The Future]]</ref> Following Joshua's death, the leadership of Heaven was unclear until Lucifer took power again for a short time.<ref name="thirteen13" /><ref name="thirteen18" /> Following Lucifer's departure, Naomi appears to have taken command of the remaining angels,<ref name="thirteen19">[[13.19 Funeralia]]</ref> but is overthrown by [[Dumah]] who attempts to reshape Heaven for the worst following the invasion of the [[Cosmic Entity]]. However, her reign is short-lived as Dumah is killed by Castiel for threatening [[John]] and [[Mary Winchester]].<ref name="fourteen19">[[14.19 Jack in the Box]]</ref>

It is later revealed that the existence of angels is what maintains Heaven, and due to the significant loss of angels through the Fall and various wars and battles only nine angels, led by [[NamoiNaomi]] remain in existence to watch over the souls in the Heaven, and that once they are all gone, Heaven will fall releasing billions of souls on to the earth.

The After imprisoning [[Cosmic EntityNaomi]] who is enraged when , Dumah takes over Heaven to reshape it to be a more merciless place and manipulates Jack to her own ends. She also co-opts Jack into turning devout humans into angels. After Dumah threatens to end Mary and John's peace to force Castiel's cooperation, Castiel kills Dumah with his [[Jackangel blade]] dies and goes to Heaven rather than .<ref name="fourteen19">[[14.19 Jack in the EmptyBox]], threatens to destroy Heaven until Castiel makes a deal to save Jack in exchange for his own life. </ref>

Fallen angels are angels that have been expelled from Heaven on the [[Host of Heaven]]'s command. When regular angels are cut off, they loose certain abilities including, [[healing]], [[resurrection]], and [[dmitingsmiting]].<ref name="five10">[[5.10 Abandon All Hope...]]</ref> However, [[archangels]] function independently from Heaven and do not loose any known abilities.

* Destructive white light - Similar to [[Lilith]]'s ability in depiction, however comes with the blue tinge that represents angelic presence, suggesting this is an extension of the angel's true form. When Castiel used this power, he ordered the humans to "Shut your eyes!" as [[Anna]] did when she regained her true form, destroying [[Alastair]]'s host. The light is powerful enough to kill a diner full of [[Eve]]'s "perfect creations" the [[Jefferson Starships]] in [[6.19 Mommy Dearest]]. <ref name="six19" /> This may have been what the Sheriff witnessed Raphael using on [[demon]]s at a gas station in [[5.03 Free to Be You and Me]]. <ref name="five03" /> [[Naomi]] later used this in [[8.19 Taxi Driver]] to try to smite [[Crowley]] forcing him to flee before she could. <ref name="eight19">[[8.19 Taxi Driver]]</ref> [[Metatron]] also displayed this in [[8.21 The Great Escapist]] when he rescued [[Kevin Tran]] from Crowley.<ref name="eight21">[[8.21 The Great Escapist]]</ref>

* [[Reality warping]] - [[Gabriel]] had shown the ability to create living beings, creatures, objects and imaginary realities out of nothing. He also showed the ability to reshape objects and human bodies, including his own vessel, and he was able to create an exact copy of himself as well.<ref name="two15">[[2.15 Tall Tales]]</ref><ref name="three11" >[[3.11 Mystery Spot]]</ref><ref name="five08">[[5.08 Changing Channels]]</ref><ref name="five19" />

* [[Smiting]] - Angels have the ability kill [[demons]] by placing a hand on the forehead of a possessed individual. Extremely powerful demons are immune to the touch of lower-level angels, e.g. [[Alastair]].<ref name="four10" /> This works on monsters and humans alike.<ref name="nine09" /> A special class of angels called the [[Rit Zien]], like [[Ephraim]], can use this to kill mortally-wounded angels and humans, but when they do, the being it is used on near-instantly explodes in a painless death.<ref name="nine09" /> The collective Host of Heaven can pool their powers together and perform mass-smitings.

** Biokinesis - Zachariah gives Dean stomach cancer and removes Sam's lungs.<ref name="five01" /> He also injures Adam, causing him to cough up blood.<ref name="five18" >[[5.18 Point of No Return]]</ref> Castiel uses this ability, similar to demon exorcism and the pyrokinetic power used by Michael on Anna, on [[Lenore]] to kill her in .<ref name="six19">[[6.19 Mommy Dearest]]</ref>** Cryokinesis - Lucifer proved capable of freezing objects by breathing on them; this occurred while he was manifesting in his vessel.<ref name="five22" >[[5.22 Swan Song]]</ref>

In [[14.08 Byzantium]], Castiel returns to Heaven to find Jack's [[soul]] so that he can [[resurrection|resurrect him]], only to find that Heaven has been invaded by the [[Cosmic Entity]]. Castiel finds Dumah alive and she accompanies him on his search for Jack's soul, only for it to be revealed that she is possessed by the Entity. The Entity uses Dumah as its [[vessel]] in its confrontation with Castiel before leaving her body to return to [[the Empty]], leaving Dumah unharmed. She appears when Castiel calls for Naomi in [[14.18 Absence]] and tells him that [[Mary Winchester]] is at peace in a shared Heaven with [[John Winchester]]. In [[14.19 Jack in the Box]], Dumah is revealed to have taken over Heaven and is reshaping it to be a more merciless place and manipulates Jack to her own ends. She also co-opts Jack into turning devout humans into angels. After Dumah threatens to end Mary and John's peace to force Castiel's cooperation, Castiel kills Dumah with his [[angel blade]] in the hallway of Heaven.
