Deanna Troi (DMU)

In an dark mirror universe Deanna Troi was a half-Human, half-Betazoid who most famously served on the ISS Voyager, as Counselor and adviser to Intendent Kira Nerys as well as the Diplomatic officer. . As a half-Betazoid, Troi was capable of extra-sensory empathy, but was incapable of reading aliens with brain structures dissimilar to Humans and other Betazoids, like the Breen and the Ferengi. Like most Betazoids, Troi had telepathic abilities; due to her half-Human heritage, however, the range of her telepathic abilities were limited compared to full-blooded Betazoids, and could usually only read the thoughts of other Betazoids, most notably her mother. Troi's empathic skills made her an important asset to Intendent Kira and often came in handy when dealing with hostile races. Since Deanna could usually tell if others were lying, she repeatedly proved herself invaluable in many suspenseful situations.
