Since Dr. McCoy in The Original Series, Star Trek has had a doctor in every subsequent series. Star Trek: Enterprise ran between 2001 and 2005. In this series, the alien humanoid Doctor Phlox was the chief medical officer of the starship Enterprise NX-01. Phlox is truly alien, both biologically and in his cultural norms. However he is tolerant of human mores and customs and indeed, embraces them. His very alienness occasionally saves the crew from attacks which exploit human vulnerabilities. It is also this alienness, with very little sleep requirements, that permits him to be almost always available to his patients. Furthermore, Phlox frequently used an array of exotic alien flora and fauna in his medical treatments, but he does not eschew modern medicine, professionally utilising the typical gamut of futuristic instruments and devices to which Star Trek audiences are accustomed. He is thus the "the prototype of the multicultural homeopathic physician of the future, comfortable with technology but knowledgeable regarding the more natural means of healing". It is these two traits which endear him to modern viewers, availability and naturalistic treatments. He is a truly unique doctor who furthers the vision of Star Trek's creator, Gene Roddenberry, of a multicultural bridge crew, since the inception of The Original Series in 1966.
