On my planet we have trans people, yeah, just like humans, but we don’t take hormones or get surgeries.
Instead there’s a magic mirror deep in the forest in the middle of a clearing. You go there and your opposite sex mirror double come out and you duel. One of you survives, and that’s how your new gender works. It’s a fair system.
Swords are the traditional weapon but it’s one of those “you only face what you bring there”.
So if you’d rather fight with guns or quarterstaff or bare hands, that’s fine, just know it won’t give you any advantage, they’ll be armed the same.
And no, you can’t cheat by learning some kind of deadly martial art. They are exactly like you except for gender, so they know all the same moves and skills.
and yeah, the mirror version of you isn’t just genderswapped, they’re also mirrored left to right. So your heart ends up on the left side, any birth marks or scars swap sides, and trans people are more likely to be left-handed than right-handed.
NO YOU CAN’T FUCK YOUR MIRROR DOUBLE
