Phlox ( mirror ) Phlox was a Denobulan military doctor in the 22nd century Terran Empire . Amoral and sadistic , he carried out brutal , horrific experiments on living beings , including sentients , in the name of medical research for the Empire . In 2155 , Phlox served as chief medical officer on the . In addition to taking care of the crew , he designed various methods of torture for the Empire ' s use . Phlox and together designed a prototype for the agony booth which would be used on multiple occasions . During Commander ' s mutiny mission , he captured a Tholian pilot and ordered Phlox to contain it and supervise its torture to determine the location of the ship the Tholians had recovered . When Captain Maximilian Forrest regained command , Phlox supervised Archer ' s torture in the agony booth until Forrest was forced to release him by . Phlox was later ordered to kill the Tholian when it woke up and sent out a distress call to other Tholian ships . Phlox happily complied , and even expressed impatience when the Tholian took too long to expire . When several Tholian ships arrived , alerted by the distress call , they attacked the " Enterprise " . Phlox entered an escape pod just before the " Enterprise " s destruction and escaped to the . ( ) While aboard the " Defiant " , told Phlox of the research she had done on the ship ' s historical database . She was fascinated to discover that in that ship ' s 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 as subversive and dangerous , and felt that Archer should restrict access to the historical database . Denobulans in the mirror universe were perceived by most Human s to be pacifistic with no real desire for war , power or revolutionary ambitions towards the Empire . It was for this reason that Archer allowed Phlox to remain on the " Defiant " while all other alien crewmembers were transferred to the . When approached by T ' Pol and 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 be 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 . 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 concubine s 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 discovered Phlox ' s treachery and was able to stop him and restore the ship ' s weapons and shields in time . This allowed the " Defiant " to gain the upper hand and destroy the " Avenger " . ( )
