Deanna Troi was a female Betazoid–Human hybrid Starfleet officer. Under the command of Captain Jean-Luc Picard, she served as the counselor aboard the USS Enterprise-D and the USS Enterprise-E. In 2379, Troi transferred to the USS Titan (Star Trek: The Next Generation; Star Trek Nemesis). By 2399, she and her husband William T. Riker lived on the planet Nepenthe with their daughter, Kestra Troi-Riker. Their son, Thaddeus Troi-Riker, died of Mendaxic neurosclerosis soon after their arrival on Nepenthe.
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 was limited compared to full-blooded Betazoids, and she 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-D and her abilities were often particularly useful when dealing with hostile races. Since she could usually determine, through use of her abilities, whether others were lying, she repeatedly proved herself invaluable in many suspenseful situations. (TNG: "Encounter at Farpoint", "Ménage à Troi", "The Loss"; VOY: "Inside Man")
Deanna was born on March 29, 2336, near Lake El'nar on Betazed. She was born to Betazoid Ambassador Lwaxana Troi and Human Starfleet officer Ian Andrew Troi. Deanna was actually the second of their two children, the first being Kestra Troi, born in 2330. However, Kestra drowned when Deanna was an infant. Stricken with grief and regret, Lwaxana removed all evidence of Kestra's existence from her own life and even repressed all memories of Kestra. She also made her husband swear never to mention Kestra again. Because of this, Deanna did not learn of her sister until 2370, when Lwaxana's memories resurfaced. (TNG: "Conundrum", "Dark Page")
As required by Betazoid custom, Deanna was genetically bonded with a Human male named Wyatt Miller at a young age. Wyatt was the son of Steven and Victoria Miller, close friends of Deanna's parents. Due to their genetic bonding, Deanna was scheduled to marry Wyatt in adulthood. (TNG: "Haven")
According to her mother, Deanna had a talent for languages as a child. (TNG: "Dark Page") During her adult life, Deanna also recalled having visited Enterprise NX-01 as a little girl, although she was not absolutely sure, as she always got "those museum ships" mixed up. (ENT: "These Are the Voyages...")
As a child living on Betazed, Deanna learned aspects of Human culture from her Human father, Ian. One such aspect was a fondness for stories set during Earth's Ancient West, which he often read to her. (TNG: "A Fistful of Datas") To fall asleep, she would ask him to sing the American song "Down in the Valley"; while this was her favorite, it was his singing that made her feel safe. (TNG: "Dark Page") As she was half-Human and half-Betazoid, she never felt trapped between the two worlds to which she belonged, instead choosing to embrace the richness of her dual heritage. (TNG: "The Emissary") She also heard stories from her maternal grandfather, who told them telepathically; something of a traditionalist, he rarely spoke, saying speech was for "offworlders and people who didn't know any better." (TNG: "Eye of the Beholder")
Deanna's father died in 2343, when Deanna was only seven years old. Even so, she remembered him fondly, and when she became pregnant by an alien energy being in 2365, she named the child after her father. (TNG: "Half a Life", "Dark Page", "The Child")
In grammar school, Deanna had to memorize Jonathan Archer's speech at the Federation Founding Ceremony. (ENT: "These Are the Voyages...") Deanna began studying psychology at the University of Betazed sometime in the 2350s. During her time there, one of her patients was Tam Elbrun, a Betazoid male who had been suffering from mental instability due to his lack of the Betazoid's natural ability to "tune out" the thoughts of others. (TNG: "Tin Man")
Janaran Falls was where Deanna and William Riker spent their last night together
Deanna Troi entered Starfleet Academy in 2355. She graduated in 2359, majoring in psychology. (TNG: "Conundrum") On her homeworld of Betazed, she met William T. Riker, a Starfleet lieutenant who was stationed on the planet. The two began a relationship sometime between 2357 and 2361, and the relationship lasted several years. After Riker was assigned to the USS Potemkin, the two planned to spend their holidays together on Risa in 2361. However, Will had to cancel their plans after he was quickly promoted to lieutenant commander – deciding to make his career his top priority, Will stopped pursuing Deanna, and the couple eventually lost contact with each other. (TNG: "Encounter at Farpoint", "Ménage à Troi", "Second Chances") By 2364, Troi held the rank of lieutenant commander. That year, she was assigned as ship's counselor aboard the USS Enterprise-D. (TNG: "Encounter at Farpoint")
Troi does not like riding horses because of their "own mind", as Betazoids become too involved in the thoughts and shifting passions of animals. (TNG: "Pen Pals")
Troi was able to beat Data in a game of three-dimensional chess, using "intuition." When faced with the Kriskov Gambit, instead of countering with the el-Mitra Exchange as is characteristic, Troi chose to leave her king vulnerable, devising a completely unanticipated response to a classic attack, and forcing checkmate in seven moves. (TNG: "Conundrum")
Deanna once said that she had never met a form of chocolate that she did not like. (TNG: "The Game") Data mentioned to Q that, when Counselor Troi was in a bad mood, she often ordered a food containing chocolate. (TNG: "Deja Q") Dr. Crusher once described Counselor Troi as loving chocolate. (TNG: "Remember Me")
Plays Poker
Plays Piano
Deanna enjoyed swimming, but didn't think swimming on the holodeck was an adequate substitute for swimming in a real ocean. (TNG: "Conspiracy") She often used exercise programs on the holodeck, though, when she needed to take her mind off frustrations. (TNG: "The Emissary")
