So I had an idea for a Good Omens fic where Aziraphale and Crowley are both demons.
(This post contains season 2 spoilers and uses he/him pronouns for both of them but that's not to say that she/her or they/them pronouns are wrong or bad, just not what I'm using)
So both of the are demons. Because of this tiktok:
Anyways, so yeah.
Here's what I'm thinking so far. Aziraphale and Crowley met in Heaven, as angels, of course. Just like we see in Season 2 Episode 1.
Aziraphale is in love at first sight. How can you not be? Just seeing the angel version of Crowley, smiling, happy, excited about the stars. Gorgeous? Yes, yes he is. So Aziraphale is seriously concerned when Crowley starts questioning things and hanging about with Lucifer and the gang.
And then, he's seriously horrified when Crowley, beautiful, gorgeous Crowley, is sentenced to Fall. That's not fair. That's not right. Crowley is sweet and perfect and amazing. Aziraphale doesn't want Crowley to Fall.
At least, not alone.
Aziraphale doesn't Fall so much as dive head first, catching Crowley in his arms and wrapping them both up in his wings. He takes the brunt of the damage when they hit the sulfur. His feathers completely burn away. It all gets a little fuzzy after that. There's a lot of pain and burning for what feels like an eternity. And then they eventually pick themselves up, memories broken or missing.
They both start working on Earth, they kind of become rivals. Who can do the worse job? Not that they have to do much since humanity is perfectly capable of ruining things on their own. So they basically just exist to please themselves and piss each other off.
But, Aziraphale has dreams of them together in Heaven. Crowley's smile when his stars were born... It makes Aziraphale's heart ache. And he wants to see that smile again. Unfortunately, the sulfur burned it away but he believes it's still there somewhere. He does what he can to protect the demon Crowley, even doing some nasty things to cover up the secret good things that Crowley does.
Aziraphale is very protective over Crowley. And he's definitely the worse of the two of them. As far as being a demon goes. He doesn't mind getting his hands dirty if it means Crowley doesn't have to.
That's why he jumped Down after him, after all. He remembers that now.
And then Armageddon... they decide to work together, officially, to prevent it from happening because they like the earth and don't want to go to war.
Um... what else.... I think Demon Aziraphale runs a tattoo shop instead of a book shop
Um... I think at some point I want Aziraphale to be like, "You're the closest thing to Heaven I'll ever need"
