Probably the only Klingon I will entertain as being genuinely good looking... Torres, played by Roxann Dawson, is half-human, half Klingon, and luckily the Klingon side is mainly in her temper and strength, not to mention a light smattering of a ridge across her forehead! There's a dark side to Torres that is somehow quite appealing.
Kes was a female telepath Ocampa who developed psionic powers (whatever that is) and evolved into a superior life form. In actual fact the character was rather dull and was removed to make way for the Seven of Nine character.
.... although in one episode, "Warlord", she was possessed by an alien warlord and became a much moer interesting character, tough and tyranical.
Seven of Nine is the designation of a Borg group consisting of nine members.
Seven was originally a human, Annika Hansen, but was assimillated by the Borg.
Later, implants were removed and she gradually became mostly human again.
There are plenty of sites out there - too many to link to - just do a search...
I'm not going to pretend that this is the best Star Trek babe site. I'm not interesting in competing with others who devote their time to this one subject, but I'd like to think I've made a decent effort in selecting the ladies that I think are worthy. Yes I've probably missed a few - but I'll get round to them one day..
