Deanna Troi (alternate timeline)

"Captain, I'm sensing a – a powerful mind!."

- Deanna Troi

Deanna Troi is a half-Human, half-Betazoid female who most famously served on the USS Enterprise (NCC-1701-D) and the USS Enterprise (NCC-1701-E), as counselor and adviser to Captain Jean-Luc Picard. 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, such as 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 the Enterprise and often came in handy when dealing with hostile races. Since she could usually tell if others were lying, she repeatedly proved herself invaluable in many suspenseful situations. She would marry and have a child with Typhuss James Halliwell. After the death of Fleet Admiral Kira Nerys in 2404, Deanna succeeded Kira as Commander in Chief of the Bajoran Starfleet and Director of Fleet Operations.
