When DS9 was in first run, I had such a crush on Jadzia/Farrell. These days though, I recognize how blind I was by not being a Nerys/Visitor guy. She's where it's at. That's not to say I haven't lusted after nearly all of them. And a few of the lads in a non-sexual man crush kinda way.
1. Sakonna 2. Kassidy 3. Nerys 4. Grilka (yeah I'm down for the rough stuff) 5. Allura/Mardah/Leeta (tie) 6. Helen Noel (I know, wrong show but any excuse to post a picture of Marianna Hill is welcome.) I know someone mentioned Female Changeling before. She was older when DS9 was in production, but Salome Jens in her younger day was one fine example of sexiness.
Young Salome Jens is also in original Outer Limits' "Corpus Earthling", with Robert Culp and Barry Atwater. With the voices of Vic Perrin and Robert Johnson ("This tape will self destruct in five seconds.")
I'd say Nana Visitor was my favorite. For a former terrorist she could come across as awfully cute even if she could probably break me in half!
You all have taken all the good ones...I'll just throw this out here and admit that if I were Sisko, I just would have traded a make-out session for the Jem'Hadar ship....though I'll bet she would be really bad at that, being a Vorta.
Of all the guest characters, I thought Gilora Rejal, the Cardassian scientist who thought O'Brien was coming on to her, was the prettiest. In fact, most of the Cardassian women on the show were quite lovely. Of course, I'm not a guy. Male viewers probably have a different opinion about what factors make a woman beautiful. I tend to notice a person's eyes first, and their smile.
For me, the best looking major character was Followed closely by - Best looking character who appeared once or twice -
Cutest (no contest) - Followed by someone who I have not seen mentioned yet - Man I thought she was cute when I saw that episode. Kira I always loved as a character, but never really found myself attracted to her even though I recognized she was attractive.
Always happen to me, I have a HD screen and it just seems to be a normal size to me. Resize now, apologies. Enjoy!
It's almost the same with me. In the 90's as a teenager I loved Jadzia a lot (I even bought the life size cardboard of her) and I never had a special interest in Kira then. But since some years I'm feeling more attracted to Kira. Maybe it's because of my age. But these are only my feelings to the characters they played in DS9. With a look to the actresses now, I'm staying with my old crush Terry Farrell.
My heart melts (sort of like Odo's...haha) for Nana Visitor as Kira. But I'll also mention another beautiful DS9 actress, Felicia M. Bell who played Sisko's wife, Jennifer.
