Deanna Troi (mirror)

In the Mirror Universe, Deanna Troi was born on Betazed, presumably in 2336. Her mother is Lwaxana Troi. Lwaxana's favourite slave was Deanna's father (Star Trek: Dark Passions, Book 1).

Troi, who grew up in the Fifth House, was told her father's identity in 2354 and subsequently left Betazed. She nevertheless became Intendant of Betazed in 2359 (Star Trek: Dark Passions, Book 1).

Troi joined the crew of ISS Enterprise-D in 2364 when it was captained by Jean-Luc Picard (TNG novel Dark Mirror).

On stardate 44010.2 in 2367, Troi discovered Geordi LaForge acting suspiciously, working with microchips. Troi placed LaForge in the agony booth and was able to determine that he was actually an inferior version of our LaForge, from another Universe entirely. With his compatriots having slipped past guard Reginald Barclay, Troi felt justified in killing Barclay (TNG novel Dark Mirror).

By 2369, Troi had taken to wearing full Klingon armour, as an extention to her role as Imzadi to Worf. Early that year, Troi visited the Intendant of Sol - B'Elanna Torres - who gave Troi a present in the form of servant girl Keiko Ishikawa. Later that year, Troi began setting her sights on soon living on planet Betazed II. Troi learnt that a man called Tomas was a harasser of women, so she had him killed for that. Troi and Worf were later visited by Bajor's Intendant Kira Nerys and her associate, Agent Seven of Corps. Nine (Star Trek: Dark Passions, Book 1).

By stardate 47104.0, Troi decided that she was beginning to look similar in attire to Kira, so she took to wearing a long blue dress. She then joined with Skrain Dukat to begin a plan to depose Kira from her position. Part of this plan was a meeting with Kira (as well as Worf and Torres) on deep-core mining chaired by Jennifer Sisko. After Troi staged a failed attempt on Kira's life which aroused Kira's suspicions, Troi used her psychological training to convince Kira she was, in fact, innocent, but this situation was eventually dispersed and Kira set about planning revenge.

Some time later, Deanna was in the process of giving birth to her and Worf's first child on planetoid New Hope, when Kira turned up in a vac-suit and murdered Troi with a phaser (Star Trek: Dark Passions, Book 2).
