Feezal Phlox was a Denobulan scientist, an expert in quantum optics. She was also the second of Dr. Phlox' three wives.
In 2152, she attended a medical conference that Enterprise NX-01, carrying Phlox, one of her husbands, also attended. She delivered a neutron microscope to the Enterprise and provided instruction on maintaining the technology.
While aboard, she became interested in Commander Tucker and attempted to seduce him. When Tucker informed Phlox of the situation, Phlox explained that such behavior was perfectly acceptable in Denobulan culture and that he should take advantage of Feezal's affections. However, Tucker was bound by Human customs and refused, much to the amusement of Phlox and Feezal. (ENT: "Stigma")
In 2161, she attended the founding of the United Federation of Planets. (ENT: "These Are the Voyages...")
Feezal was played by Melinda Page Hamilton.
In the final draft script of "Stigma", Feezal was characterized as "an attractive Denobulan female in her 30's." [1]
