Duma

Duma is an angel who is searching for Jack. She is one of the last ten or so angels alive.

History
Duma agrees to meet with Castiel at the Heavenly Portal to discuss the situation with the Nephilim Jack as long as Castiel comes alone. Though Dean Winchester offers to accompany Castiel, Castiel refuses Dean's help.

Outside of the portal, Castiel and Duma meet and Castiel tells her that he must locate Jack. When Castiel asks if the angels have Jack, possibly in Metatron's old cell, Duma states that they do not. Duma tells Castiel that if the angels had Jack, he would not be imprisoned but rather put to work. Duma explains to Castiel that the angels' numbers have been greatly diminished since the Fall of the Angels and their race is going extinct. In order to make more angels, something that hasn't been done since the dawn of Creation, they will need a powerful force. Castiel realizes that Duma means Jack and points out that Jack may not be willing to help. Duma states that Jack might not have a choice, causing Castiel to realize that the angels want to enslave Jack to do their bidding.

As Duma tells Castiel that Jack "belongs to all of us," two more angels emerge from the portal and congratulate Duma on delivering Castiel as promised. One of the angels tells Castiel that they have heard that Castiel has influence with Jack and thus Jack will listen to him. Castiel, however, refuses to help the angels enslave Jack.

Taking Castiel's hand Duma pleads with Castiel to come with them, but Castiel shoves her away in horror of what the angels are planning. All four angels draw their angel blades and Castiel quickly knocks Duma back with a blow to the face before fighting with her henchmen. After Castiel knocks the other two angels away, Duma comes up from behind Castiel and holds an angel blade to his throat.

Before the confrontation can go any further, the four angels are interrupted by the appearance of Lucifer who orders Duma to release Castiel. Staring at Lucifer in terror, Duma hesitates to comply until Lucifer makes his eyes glow red and moves as if to combust the angels. Finally, the terrified Duma releases Castiel and flees through the portal back to Heaven with the other two angels, leaving Lucifer exhausted from intimidating them in his weakened state.

After escaping with Anael, Lucifer meets with Duma and three more angels outside of the Heavenly Portal, attempting to convince the angels to work with him. Though Duma orders Lucifer killed, Lucifer points out that even while weakened, they still don't have the ability to actually kill him though Duma wants to try. Though Duma continues to resist Lucifer's attempts to convince her, Lucifer claims that he knows how to make more angels since he saw how God did it and can potentially even restore the angels' wings if they make him the undisputed Ruler of Heaven. Duma ultimately agrees and the angels accept Lucifer as their new leader with Anael at his side.

Duma later appears before Lucifer to inform him that what few angels they can spare are searching Jack, but are having no success. Duma refuses to get in the middle of the squabble between Lucifer and Anael and departs to continue the search after Lucifer becomes threatening towards her.

Shortly thereafter, Castiel arrives in Heaven to seek out the angels' help in finding the archangel Gabriel who he reveals is still alive. He also explains he needs them in fighting an Alternate Michael. Duma arrives with two other angels and though wary, hears Castiel out. Duma decides that maybe they can help each other after all and leaves Castiel sitting in Heaven's Throne Room for a long time. Finally, Duma returns, asking about Gabriel and getting him to Heaven. When Castiel admits that he doesn't know where Gabriel is and asks Duma to send a few angels to search for him, Naomi arrives and explains that Duma can't. Naomi then takes Castiel to her old office to speak with him, leaving Duma and the other angels behind.

Powers and Abilities
Duma appeared to be a regular angel with all the powers of one.
 * Angelic Possession - Like all other angels, she requires a vessel to walk the Earth and their permission to do so.
 * Immortality - As an angel, she would never age or die unless killed.
 * Invulnerability - As an angel, she is invulnerable to most forms of harm.
 * Super Strength - As an angel, she is stronger than humans, monsters and most demons. However, she is no match for higher-level angels such as Castiel.

Weaknesses
She possessed all the regular weaknesses of an angel.
 * Angel Blades - Like most angels, she could be killed by an angel blade.
 * Higher Angels - In a fight, she was easily thrown aside by the Seraphim Castiel, only defeating him when she caught Castiel by surprise from behind. When the Archangel Lucifer threatened her, she fled in terror. Even in his weakened state, Lucifer stated that she was unable to kill him.
