In the mirror universe, Phlox was a Denobulan military doctor serving aboard the Imperial Starship Enterprise. Like the Phlox of our universe, the mirror Phlox was also cheerful... cheerful about torturing humanoids, creating more effective torture devices, and dissecting live animals. Unlike the Phlox in the normal universe, he wore a black leather military uniform, had no real sense of ethics (medical or otherwise) and behaved sociopathically when treating his patients.
Phlox and Major Reed together designed a prototype for the agony booth. He also supervised the torture of the Tholian captured by Archer to determine the location of the Terran ship. When Captain Maximilian Forrest regained command and ordered Phlox to kill the Tholian, who was sending out a distress call to other Tholian ships. Phlox happily complied, and even expressed impatience when the Tholian took too long to expire. By then it was too late. Several Tholian ships arrived and attacked the Enterprise. Phlox escaped the Enterprise in an escape pod just before its destruction and made it to the USS Defiant. (ENT: "In a Mirror, Darkly")
While aboard the Defiant, T'Pol told Phlox of the research she had done on the ship's historical database. She was fascinated to discover that in the normal universe, a United Federation of Planets was formed by Earth and other alien worlds, and that all members were regarded as equal. Phlox viewed such talk was subversive and dangerous, and felt that Archer should restrict access to the historical database.
Phlox "examines" a patient
Denobulans in the mirror universe were perceived by most Humans to be pacifistic with no real desire for war, power or revolutionary ambitions towards the Empire. It was for this reason that Commander Archer allowed Phlox to remain on the Defiant while all other alien crewmembers were transferred to the ISS Avenger.
When approached by T'Pol and Soval to help them destroy the Defiant and stop Archer from crowning himself Emperor, Phlox resisted. He genuinely respected Archer's abilities as both an officer and warrior. Furthermore, he agreed with Archer that the current Emperor was corrupt, incompetent and responsible for the Empire's continuing losses, and that Archer might have been able to turn the tide in favor of the Empire. When both T'Pol and Soval insisted that Archer's plans were delusional, Phlox pointed out that with the Defiant, Archer's seemingly delusional plan to become Emperor would now be a reality. Furthermore, Phlox threatened to report their conspiracy to Archer.
Phlox defends himself against Tucker
Both T'Pol and Soval pointed out that if Archer were unsuccessful, both he and his crew would be executed for treason. Furthermore, they pointed out that if one were to save the Emperor's life, by custom, the Emperor would grant that person anything they desired, such as a medical laboratory with unlimited funding and possibly concubines as well. The latter argument seemed to convince Phlox to help stop Archer.
Phlox attempted to sabotage key components of the Defiant, allowing the Avenger to attack and gain an early tactical advantage. However, Commander Charles Tucker discovered Phlox's treachery and was able to stop him and restore ship's weapons and shields in time. This allowed the Defiant to gain the upper hand and destroy the Avenger.
- Phlox's fate remained unclear, although its reasonable to assume that he was executed along with T'Pol and the other mutineers, if not by Archer, then by Empress Hoshi Sato. (ENT: "In a Mirror, Darkly, Part II")
- Like his counterpart, Phlox was portrayed by John Billingsley.
