T'Pol - Mirror Universe

Mirror Universe

A two-part episode in the fourth season, "In a Mirror, Darkly", introduced a Mirror Universe version of T'Pol. This version is more cynical and openly emotional than her "real universe" counterpart, and is also openly sexually manipulative, particularly of Commander Tucker.

The Mirror Universe T'Pol underwent pon farr at some point in the recent past (it is not revealed if this was a natural occurrence or the result of the same virus affecting the "real universe" version of T'Pol in Bounty), and Trip mated with her in order to get her through it. Physically, she differs from her real universe counterpart in that she has long, blonde hair and, like other female officers in the Terran Empire, she wears a two-piece uniform with a bare midriff (although after transferring to the captured USS Defiant (NCC-1764), she adopts a TOS-style miniskirt uniform temporarily until she is able to obtain a more standard Empire uniform).

Mirror-T'Pol's mind meld abilities appear to be somewhat more advanced than those of her counterpart, as she is capable of placing a form of post-hypnotic suggestion into the minds of those with whom she melds; since the real universe T'Pol had only recently learned how to meld, it is unlikely she had yet achieved this level of melding proficiency. She also appears to be more emotional than her counterpart, showing open sarcasm and contempt for Archer, and is seen to either grin or snarl (depending on one's point of view) during a brief bout of hand-to-hand combat with Hoshi Sato.

Eventually, Mirror-T'Pol is forcibly transferred from the Defiant to the ISS Avenger when Jonathan Archer attempts to rid his ship of all alien crew members. T'Pol becomes convinced that Archer will never allow Vulcans to be equals, and tries to stop him from taking over the Empire. Mirror-T'Pol was inspired by reading the historical logs of our universe's Defiant, which revealed a universe where Humans, Vulcans, and other aliens lived as equals in a benevolent Federation. After recruiting the ISS Avenger's alien crew members to the rebellion, T'Pol is caught and interrogated by Archer. Her ultimate fate is not revealed; although both Archer and Hoshi Sato express a desire to have her executed following her interrogation, the Defiant immediately enters battle and this does not occur on screen.

During the episode's stated date of January 2155, T'Pol foreshadows future events, such as the fall of the Terran Empire after several centuries (which would be chronicled in the Mirror Universe episodes of Star Trek: Deep Space Nine.)
