Dax (Star Trek)

Dax is a fictional character on the television show Star Trek: Deep Space Nine.

Dax is a Trill symbiont, a very long-lived slug-shaped entity that is hosted by a succession of humanoid Trills, a process called "joining". Each of the hosts has access to the memories of the previous hosts. Two of Dax's hosts, Jadzia Dax and Ezri Dax, were regular characters on Deep Space Nine. Dax has had a total of ten hosts:

1. Lela Dax;
2. Tobin Dax;
3. Audrid Dax;
4. Emony Dax;
5. Torias Dax;
6. Joran Dax (Jeff Magnus McBride in episode "Equilibrium" and Leigh J. McCloskey in "Field of Fire")
7. Curzon Dax (Frank Owen Smith - episode "Emissary");
8. Jadzia Dax (Terry Farrell);
9. Verad Dax (John Glover - episode "Invasive Procedures")
10. Ezri Dax (Nicole de Boer).

In an alternate future, a descendant of Jadzia's, Yedrin Dax (Gary Frank - episode "Children of Time"), was shown to be hosting Dax.
