Alright, I won't be delving too much into this theory for now, but I wanted to discuss the topic of angel Crowley and specifically her identity. (I will be referring to Crowley with all pronouns in this post.)
So, as somebody who's been in the Good Omens fandom since, well, the release of season 2, I've been trying to think about which angel Crowley would have been in the past and, more specifically, her relationship with God. There are many theories in the past such as her being Raphael or even Jophiel, which are fine but I don't inherently subscribe to. However, let's get a better look at who exactly these angels are.
Disclaimer, I am doing the bare bones of research for this right now as this is more-so a silly little thing. That and I am not an expert in religion at all.
Raphael, as stated by a quick search, is a "protector" and "healer" and one of the main, well-known archangels. In fact, he is one of the strongest angels and can outmatch most other angels he is paired with. Although Good Omens does not necessarily line up with the Bible and its teaching 1:1, I still look to it to form thoughts and opinions on certain things. Raphael, unlike Crowley, is not a fallen angel and therefore should still exist within Heaven and be a separate angel entirely.
Moving on, we can now look to Jophiel another common theory. Honestly, I see this as a cute theory, being the angel of "art", "beauty", and "wisdom". When I think of her, I associate her with "love" which would make Crowley a being of love. I think this is lovely (no pun intended) idea as I see angels as being of love, at least they are supposed to be. Similar to Raphael, Jophiel is an archangel who did not fall.
It would make more sense for angel Crowley to be Jophiel rather than Raphael since Jophiel, in my opinion, would be more inclined to beauty and creation. Crowley was a starmaker in the past, an angel that created a beautiful thing for humans to witness. However, I don't think certain aspects of both angels line up as they should when it comes to Crowley.
These theories, however, are on the right track. In season 2, episode 6 (yes, I know, the dreaded episode), we are met by this quote/scene between Muriel and Crowley:
"It's all confidential. I can't show it to you. I mean, I couldn't open it if I wanted to. I don't have clearance. You'd have to be a Throne or a Dominion, or above."
Of which Crowley opened the file easily and responded with:
"I haven't always been a demon, and they never change their passwords."
So, keeping that in mind, we must turn to the exact rankings of angels. I've found that the rankings are as such:
HIGHEST ORDER
-Seraphim
-Cherubim
-Thrones
MIDDLE ORDER
-Dominions
-Virtues
-Powers
LOWEST ORDER
-Principalities (Aziraphale <333)
-Archangels
-Angels
Which is a bit confusing considering Archangels are considered one of the highest powers in Good Omens, below the Metatron, of course. I forgot where I had seen these, but there MAY be a distinction between "archangels" and "Archangels" (yes, the capital matters.) In that way, it would make sense, that instead Archangels are somewhere within the Highest Order.
Having established that, we can determine that Crowley was either a Dominion, Throne, Cherubim, Seraphim, or an Archangel. And wow, that is a lot to look through when determining who she would be.
Now, to my theory on who I believe angel Crowley to be. Personally, I see them as "Kokabiel". When looking him up, Kokabiel is said to be a "holy angel" or even a "high-ranking angel". Now, I'm unsure of what exactly they would be in the ranking of angels above, but I think it's safe to assume via this description that she is relatively powerful. Our beloved Crowley is a starmaker and Kokabiel is quite literally known as the "angel of the stars". Not to mention that Kokabiel is a fallen angel which would match up with the Crowley we know today.
The angel Kokabiel was known to be dismissive at times about worldly concerns which may go against our idea of Crowley. But in some ways, it lines up. We know, in the nicest way possible, that Crowley is a selfish being. He desires to protect those closest to him or the things he cares about most in general. Crowley had fallen in love with their stars and it would make sense that he would choose to protect them dearly before even thinking of humans.
Moving on a bit, I want to discuss Kokabiel and her relationship to God. Honestly, I believe that Kokabiel was one of God's if not God's favorite angel. This may seem confusing at first and a bit too "serious" considering I am claiming that Crowley/Kokabiel is God's, the Highest Almighty being, favorite creation. Looking into it further, however, seems to allow something to click in my mind.
In the Bible, Lucifer is the one to turn into the Serpent of Eden. Lucifer was the one to tempt Eve into eating the apple, thus spurring the common story shared today. So why is Crawley the Serpent in our story? Sure, this can merely be of plot convenience and serve only to move the story the long, but I believe that it has a purpose. God had handed down this fate unto Lucifer. Yet in Good Omens, Crawley was given this punishment instead. This implies that they had some sort of personal relationship with God.
Again, these are all just a small collection of theories on certain ideas regarding Crowley's early identities. I could be wrong, and I most likely am, but these headcanons are all in good fun!
