#I admit I'm largely breaking rule one and not researching for these little herbalist!Zuko shorts

how would you approach writing nb!zuko?

Gonna make this a more general "how to write someone you're not" reply.

So whenever you're writing a character from a background you don't share, step one is to do your research. This applies to fantasy worlds just as much as it does to real world based stories, because while fantasy characters don't share the same history as our world, your readers do.

Never discount the baggage a reader is gonna bring, and never use it as an excuse to get lazy on the research. Especially look for no-goes like stereotypes that you'd be way better off avoiding. Where ever possible, try and find first-hand accounts.

Next you need to decide how the world you're working in will interact with this part of your character.

Is it like our world, where terms like non-binary are known but there's still a lot of antagonism from certain quarters?

Are you writing in a world where these terms aren't common yet, and the character might not have adequate ways of expressing their identity? (Not to be confused with the people themselves being uncommon--LGBT+ peeps have always been around.)

You can also have a world where such things are commonly known and accepted and treated as no big deal, which can be really relaxing to read, for real, we do not always need to be persecuted even in fake worlds. Do what's best for your story, but realize that making the world a better one than ours is completely legit, because you are the one choosing.

Culture-wise, I personally think Avatar feels like a world where different genders and orientations haven't yet been vilified. There's fairly compelling evidence that a lot of cultures in our world acknowledged other genders/orientations and were cool with them, but started repressing their own people/traditional ways of life once other cultures got all up in their business. So I'd probably write one or more of the Nations as being totally fine with such things, and try to figure out what roles (if any) those characters would commonly fill.

Like maybe non-cis people are considered super spiritually in tune in the Fire Nation, and a lot of them get recruited as Fire Sages. Or in some areas of the Earth Kingdom, having your gay brother and his husband live with you to help raise your kids and be a big supportive family is totally normal. You ask a kid in Omashu who their mom and dad are, and they can rattle off a whole list. It's really confusing to them when that new refugee from the colonies only has one mom and one dad, did the rest of them die in the war?

(Honey you can't ask that, we're so sorry--)

So that's research and culture. From there, it's just character. There is one very very important rule when writing a character from a group you're not a part of:

Write them as a person.

Specifically, that means rounding them out: hobbies and interests and quirks and pet peeves that have nothing to do with their gender/orientation. You know. Like a person.

You'll only really run into troubles if you try to make the bulk of their character be their "otherness" from you. Do not treat them as an exotic race. That's how you get things like male authors writing about females character's breasts bobbing boobily as they bounce up the stairs. Your character is a complex human being who is not much different from you; treat them like it.

Also a general rule is "if you're not from the group, don't write a story centered in the group's problems, because it's not your story to tell and you're probably gonna mess it up".

AKA: If you aren't non-binary yourself, it's totally awesome and fine to write a story about a non-binary Zuko, as long as you've researched and thought things through. It is not so great to write a story about the issues non-binary people face, featuring Zuko.

It's about the emphasis: is Zuko's plot the important one and oh hey he's non-binary as one part of his character, or is Zuko being non-binary a primary plot driver?

Former is all green, go go go. Latter is yellow, caution, question your life choices and why you think you're qualified to write this story in an authentic manner.

Note that's not a red-means-stop. It just means you should really check your motivations, double down on your research, and probably see if you can round up some non-binary beta readers.

tl;dr: Google the "How to write straight characters" panels from various conventions, I know at least the NerdCon one is easy to find the audio for. Learn via straight-faced satire. Enjoy.
