Dagon

Dagon is a Prince of Hell, one of the first demons created by Lucifer and a retired general of the armies of Hell.

Background
Dagon is the only female among the Princes of Hell, the first generation of demons after Lilith, created by Lucifer himself.

They acted as generals of Hell until Lucifer was imprisoned. Despite being the rightful heirs to Lucifer's throne, Dagon and her brothers Ramiel and Asmodeus opted to retire on earth with only Azazel assuming rule over Hell to continue their father's work. In The British Invasion, it is implied by Lucifer that at some point in the past, she had somehow failed him.

Season 12
In Stuck in the Middle (With You), Ramiel tells the Winchesters that Dagon has taken an interest in Lucifer's son shortly before they kill him.

In Family Feud, Dagon appears as Kelly Klin

e is attacked by two angels and causes both angels to combust. Dagon takes Kelly to a warehouse where she tells Kelly that her child is a boy and sees him as the best hope for everyone. Dagon offers to protect Kelly and the two leave together. As they leave, Lucifer senses that Dagon is with Kelly and smiles and calls out Dagon's name.

In Somewhere Between Heaven and Hell, Castiel investigates the angels Dagon killed and finds video footage of it. Castiel recognizes Dagon and later calls the Winchesters to warn them about her. Castiel tells them all he knows of Dagon is stories and rumors about her psychotic savagery.

In The British Invasion, Dagon receives an unexpected message from Lucifer who wants to make sure she is protecting Kelly and the baby well. Dagon confirms that she is doing her best, to which Lucifer warns her not to disappoint him again. By morning, Dagon is ready to relocate Kelly to a new hideout, but Kelly refuses and wants her baby checked out because she is experiencing weird pain in her stomach. Dagon reluctantly takes Kelly to a doctor who examines Kelly and initially says everything is fine. When Dr. Turner notices something off on the monitor, Dagon uses her powers to make him ignore it and reassure Kelly once more.

To cover their tracks and erase Kelly's medical record, Dagon orders Dermott Culp to dispose of the doctor. Having previously ordered Dermott to burn down the warehouse she and Kelly were once at, hunter Eileen Leahy decided to follow Dermott and manages to kill him. While Dagon is out buying suppliments for Kelly recommended by Dr. Turner, Kelly is lured away by Eileen's friends, Sam and Dean Winchester. They try to take her back to their place but Dagon finds them. She teleports Kelly back to their hideout.

Dagon believes Kelly can't be trusted so she handcuffs her to the bedpost. When Kelly argues that she was simply worried about her baby, Dagon tells her that the baby is indeed fine, but Kelly herself is going to die because birthing a Nephilim is always fatal; it is why Kelly is suffering from small pains, which are bound to increase in intensity.

Powers and Abilities
Dagon is a Prince of Hell and thus one of the most powerful demons to ever live.
 * Demonic Possession - Like all demons, Dagon requires a vessel to walk the Earth.
 * Immortality - As a Prince of Hell, Dagon is one of the first demons and thus several millennia old.
 * Invulnerability - As a demon, Dagon is invulnerable to most forms of harm. As a Prince of Hell, she is invulnerable to common demonic weaknesses such as the demon-killing knife and angel blades. This makes her almost impossible to defeat. She was shot several times by Dean and Mick Davies without once flinching.
 * Molecular Combustion - Simply by touching an angel, Dagon was able to make them combust into dust.
 * Teleportation - Dagon was able to quickly teleport behind an angel to kill him after killing another angel just seconds before. She also avoided a bullet from The Colt a second before it reached her.
 * Electromagnetic Interference - When Dagon killed two angels, a nearby security camera was fried.
 * Mind Control - Dagon was able to mentally make a doctor tell Kelly that "everything looks a-okay."
 * Weather manipulation - Dagon's appearance was enough to cause high winds and lightning strikes.
 * Telekinesis - With a wave of her hands, Dagon was able to throw the Winchesters, Mick Davies, Eileen Leahy and Renny Rawlings around.

Weaknesses
Due to her status as a Prince of Hell, Dagon has very few weaknesses.
 * The Colt - It can kill Princes of Hell as seen with Azazel's death.
 * The First Blade - It can kill anything.
 * Death's Scythe - It can kill anything.
 * Lance of Michael - It is capable of killing a Prince of Hell as seen with Ramiel's death.
 * Primordial Entities - God, Death, the Darkness, and the Archangels could annihilate Dagon effortlessly.

Personality
Castiel describes Dagon as a savage and psychotic individual. Although Dagon has yet to display this side of her personality, Dagon is very ruthless. She murders two angels without hesitation and orders an innocent doctor to be killed simply to cover her tracks.

She seems very fascinated in Lucifer's child, believing him to be a savior. She takes care of Kelly and tries to fulfill her every need and want, until Kelly sneaks out of their hideout, forcing Dagon to handcuff her. It is then that Dagon tells her, with a hint of amusement, that Kelly is going to die giving birth to her child.

Dagon's relationship with Lucifer is unclear. She failed him once before and maybe trying to regain his favor by protecting his child. So far, she has made no mention of her brothers.

Physical Appearance
Dagon's vessel is that of an Asian woman in her mid to late-40s. Dagon dresses her in dark leather and wears equally dark make up. As a Prince of Hell, Dagon's eyes glow yellow.

Lore
Supernatural depictions of Dagon (both as demon and female) are contrary to real lore.

Dagon (Hebrew: דגון‎‎, Tib. Dāḡôn) or Dagan (dda-gan 𒀭𒁕𒃶) is an ancient Mesopotamian Assyro-Babylonian and Levantine (Canaanite) deity. He appears to have been worshipped as a fertility god in Ebla, Assyria, Ugarit and among the Amorites. The Hebrew Bible mentions him as the national god of the Philistines with temples at Ashdod and elsewhere in Gaza. It always depicted him as a male deity with fish-man form.

A long-standing association with the word for "fish" dâg, perhaps going back to the Iron Age, has led to an interpretation as a "fish-god", and the association of "merman" motifs in Assyrian art (such as the "Dagon" relief found by Austen Henry Layard in the 1840s). The god's name was, however, more likely derived from a word for "grain", suggesting that he was in origin associated with fertility and agriculture. This image furthered an evolutionary belief that both men and fish had evolved together from the primal waters.

There are three places where Dagon is mentioned in the Bible. The first mention is Judges 16:23, where we are told that Dagon was the god of the Philistines. The Philistines offered “a great sacrifice” to Dagon, believing that their idol had delivered Samson into their hands. First Chronicles 10:10 mentions a temple of Dagon in which the head of King Saul was fastened. Then, in 1 Samuel 5, Dagon is brought to humiliation by the True God of the Israelites.

In 1 Samuel 5, The Philistines had captured the Ark of the Covenant, and they carried the ark into Dagon’s temple and set it beside Dagon. When the people of [the city of] Ashdod rose early the next day, there was Dagon, fallen on his face on the ground before the ark of the Lord. They took Dagon and put him back in his place. But the following morning when they rose, there was Dagon, fallen on his face on the ground before the ark of the Lord. His head and hands had been broken off and were lying on the threshold; only his body remained. That is why to this day neither the priests of Dagon nor any others who enter Dagon’s temple at Ashdod step on the threshold. The Lord’s hand was heavy on the people of Ashdod and its vicinity; he brought devastation on them and afflicted them with tumors. When the people of Ashdod saw what was happening, they said, ‘The ark of the god of Israel must not stay here with us, because his hand is heavy on us and on Dagon our god.

Dagon also figures into the story of Jonah, as well, although the deity is not mentioned by name in Jonah’s book. The Assyrians in Ninevah, to whom Jonah was sent as a missionary, worshiped Dagon and his female counterpart, the fish goddess Nanshe. Jonah, of course, did not go straight to Ninevah but had to be brought there via miraculous means. The transportation that God provided for Jonah (a great fish) would have been full of meaning for the Ninevites. When Jonah arrived in their city, he made quite a splash, so to speak. He was a man who had been inside a fish for three days and directly deposited by a fish on the shores of Assyria. The Ninevites, who worshiped a fish god, were duly impressed; they gave Jonah their attention and repented of their sin.
