My current main character here, Aloy Vizsla, Is actually trans. And it was when I first began to write her back in early 2019 that I myself discovered that I am MTF trans, I now use she\her pronouns and so does Aloy.
The short of it is that I was debating whether to play another male character or a new female character and through the thought process I learned that getting into the heads of my male characters made me dysphoric and
very uncomfortable.
Aloy's sheet doesn't actually explain that she's trans because, Despite what it means to me, It's not a big part of her character and no one actually knows yet IC, Not even her wife.
There is actually a factory submission for her cyber\bio implant package which details it's purpose in her medical transition. It more or less explains that she used her career as a bounty hunter(ex-bounty hunter now) to fund the surgeries and implants. She has artificial ovaries, Bone reconstruction and a number of other modifications from her original body that let her control hormones and other things via neural-linked cybernetics and bio-implant combinations. Even a duraplast plated skull to keep the control module protected from imp\ion.
Aloy is the first character I've written like this, While I had another in a fantasy rp that involved shape shifting magic, And a second on chaos,
Kaila , Who i've sadly set aside, But is a bit of a mystery. She uses she\her pronouns but the gender is labeled "redacted" on her sheet for chits and giggles, Being an imperial experiment and all. There are a couple who know the truth but that's a very private matter
Those are the only three currently. I don't have any Non-binary or otherwise GNC characters, But that's not to say I won't in the future. I personally enjoy a bit of androgyny in my more rogue-ish personas, And I'll probably have a non-binary dark jedi or smuggler some day just because I love the style. Dark and mysterious, But also a flamboyant personality that doesn't care what anyone else thinks, It's always drawn me in lol
Hm. Might be time to write a pirate captain actually, Hold that thought xD
