I'm nonbinary, so as soon as I thought about creating a character I immediately knew I was going to make one that was neither male or female. That isn't an opportunity I get very often. I decided to choose from a species where that's a pretty normal biological thing just because I wanted it to be something of a non-issue. It still comes up pretty often when deciding what to wear off duty or interacting with very binary-gendered species, so it also provides some interesting narrative opportunities.
Not exactly sure how subconscious this is, since this is a memory from Iniko's past, but jhe still has nightmares about it and is a bit paranoid because of it. This is during the Romulan occupation of Duronis II, when Iniko had joined up with a group of protestors hoping to oust the Romulans.
