Do you know which Buffyverse character definitely exists beyond the gender binary? Glory.
She's a god, so she already exists outside of things like human comprehension and categorization so she definitely doesn't fit inside things we've created like rules and norms or social constructs like gender. She's also incredibly old and has existed for a very long time so she existed before such a thing as gender even existed, since human beings made that as a concept.
According to Giles and Tara, Glory "pre-dates the written word" and is "that which cannot be named". How much more gender binary-defying can you possibly get than being un-nameable and older than words like boy and girl, masculine and feminine, he and she and they??? Like us being the ridiculous mortal humans we are just gave Glory some pronouns because that's what we do but she definitely exists outside of our language and comprehension of gender. Glory just didn't have pronouns or a gender (or if she does we don't know how Glory identifies) so we assigned her one.
The entire thing where she shares a body with Ben I mean how much more trans person feeling trapped into a body that doesn't belong to them could she be??? She got sent to our dimension and crammed into a body she doesn't belong in!!!!!! I am screaming
Glory saying to Dawn, "This body? It's just a rental, Dawnie. Being human… it's like a costume for girls like you and me. Being something else…That's what we are." (5x21 The Weight of the World) Just!!!!! "a costume" and "being something else" like????? Glory is literally something else!!! Also, so is Dawn, but that's for another post haha. (Credit to @summrsbuffy for this one, they came up with it)
So now I headcanon that Glory definitely would ask her minions to coin neopronouns just for her. She'd probably say something about how she's "too fabulous to be referred to by the same words used for something as common as mortals".
You know what else Glory would love? Emojiself pronouns. She'd be using ones like 👠/👠s, ✨/✨s, 💁🏼/💁🏼s, and 🫧/🫧s
Have you ever heard someone try to address a group of people and come to the realization that so much of our language is gendered and watch them cycle through options like "ladies and gentlemen" or "prom king and queen" or "sir or madam" and try to come up with something that won't exclude non-binary people?? Or come up with a non-gendered specific compliment? They usually end up saying the most bizarre things ever!! Well, I have decided that this is exactly what Glory's minions are doing when they compliment her! They are saying the weirdest things ever because they are trying to compliment their god in a non-gendered way!!! They seriously say things like "glittering glistening Glorificus" and "your inconceivableness" who says things like that??? This is now the only explanation I will accept for the utter ridiculousness of their Glory praise.
Okay I am going insane thinking about this!!! I just found a list of all the things the minions call Glory and there's only one definitely gendered term in the entire list!!! Every other time they call Glory something gender neutral and mostly refer to her as some variation of her name or "one" just!! Look at this: "Most beauteous and supremely magnificent one, Most tingly and wonderful Glorificus, Shiny special one, Your elaborate marvellous one, Your terrifically smooth one, Your creamy coolness, Your extremeness, Mistress, Perturbed yet ultimately merciful one, Most silky and effervescent Glorificus, Your most fresh and cleanness, Great one, Your eminence, The magnificent glory, The beautious glory, Magnificently scented Glorificus, Your inconceivableness, Most glamorous yet tasteful one, Your highness, Sacred Glorificus, Oh... Thou, Stunning one, Your unholiness, Glittering glistening Glorificus, Your scrumptiousness, The God, The Glorious One, Your grace, Her magnificent incandescence, Her magnificence, Oh brutastic one, oh sweaty naughty feelings causing one"
This is just so !!!!!!!!!
Glory is non-binary!!! This is my headcanon forever now I don't think my mind could possibly be changed
