Commander Jadzia Dax, played by
Terry Farrell
Dax is a trill, a symbiotic life form that can live a very long time --- hundreds, maybe thousands of years --- and is transplanted from host body to host body as each wears out or dies. Jadzia is the latest host, and in keeping with trill tradition she takes the alien’s surname, becoming Jadzia Dax, most often referred to as Dax. She serves aboard the space station Deep Space 9 under Commander (later Captain) Ben Sisko, whom she knows from her days of being implanted in the host body of the previous donor, a warrior named Curzon. Because of his long relationship with Curzon, and out of respect to the trill, Sisko often refers to Jadzia as “old man”, which is a little confusing. Initially, Jadzia is pestered by Doctor Julian Bashir, who falls in love with her, but eventually she falls for Worf, the Klingon security chief of DS9, and marries him.
Again, somewhat like Uhura and unlike most of the TNG females, Dax is treated almost like a man (given that she has the trill inside her and that all previous hosts were male, this is not that surprising) and acts quite the tomboy. She rarely seems to indulge in feminine trappings or be interested in feminine things, other than her romantic interests. She plays games of skill and chance at Quark’s with the abandon and acceptance of any other man, and she can fight and protect herself as well as any of them. She frequently leads missions, holding the rank originally of Lieutenant and then later Lieutenant Commander, and having her special relationship with Sisko gives her access to the station’s commander she might otherwise not have.
Dax is killed in the finale of the sixth season by Gul Dukat, but though Jadzia dies the symbiont is saved and later transplanted into another host body, who carries it through the final season to the conclusion of the show. After her heroics and sacrifice, Worf believes his late wife has earned her place in
Sto’vo’kor, the Klingon heaven, somewhat equivalent to Valhalla, even though she herself is not of Klingon blood.
