aaactually a lot of the more humanoid aliens *might be* hybridized. it’s never confirmed but at the very least cross-species genetic tampering comes up as a minor plot point—i can’t say more without spoiling tho
Since I saw a lot of this as a kid, I know some shenanigans eventually go down with Delenn and an awful head of human hair, though the circumstances aren’t really clear in my memory. I remember watching relevant episodes with my grandmother, and she has always had different tastes regarding what is interesting or good in media than I did, so she was really emphatic about the love story that apparently goes along with this crappy hair and I was just really uncomfortable, both with the love story and the hair. I think at the time I believed Delenn ‘looked better’ because I hadn’t yet developed a deep appreciation for women with no hair/who didn’t look aggressively feminine Barbie style (see current tragic and conflicting passionate burning love for the entirely bald and not sweet Doc Yewll). I remember clearly though, staring at my grandmother’s Delenn action figure and feeling some deep discomfort on her behalf, like her body had been violated.
This may or may not be related to what you’re saying, haha.
But, again, to spin off on some nebulous personal junk, I don’t really remember all the context. I can’t remember clearly how Delenn felt about all this, nor do I have clear impressions of any other characters at all but Londo and G'Kar and maybe someone blue exploding at some point. Just like my childhood clear memories of Odo and Quark and not much more of DS9, haha. I remember the colors of Quark’s bar very strongly, I liked how warm they were, they made our basement (where we had a tv) feel nice.
I was old enough to properly understand these shows when they aired, but I was very private about enjoying media even then and I had this weird feeling that I wasn’t supposed to be really seeing these shows, I was only happening to catch things if my dad and grandmother watched them. So I never saw things regularly or in order. I think I also sensed early on that I liked these shows for different reasons than my dad and grandmother did and that these would be a problem if I expressed them, so I just decided not to torture myself. I had a lot of really complicated and tangled feelings about everything and did primarily what I thought would make me less likely to be commented upon, often to the point of just not pursuing things I liked.
A lot of this is still left over in me, 20+ years later, though I’ve been trying to get to the heart of it all and undo some of it.
