Commander Deanna Troi // is a main character in the science-fiction television series Star Trek: The Next Generation and related TV series and films, portrayed by actress Marina Sirtis. Troi is half-human, half-Betazoid and has the psionic ability to sense emotions. She serves as the ship's counselor on USS Enterprise-D. Throughout most of the series, she holds the rank of lieutenant commander. In the seventh season, however, Troi takes the bridge officer's examination and is promoted to the rank of commander, but continues as counselor. Deanna and Riker were the last Star Trek: The Next Generation main cast members to appear on television in the 2005 finale of the later Star Trek: Enterprise TV show, until Patrick Stewart announced he would return to the role of Jean-Luc Picard in 2019 in Star Trek: Picard. Deanna appears in all four TNG theatrical films, and also in three episodes of Star Trek: Voyager.

Her romantic interests, family, and personal life are plot elements in many Star Trek: The Next Generation episodes over the course of the series.
Deanna Troi was born on March 29, 2336, near Lake El-Nar, Betazed. Deanna's parents are Betazoid Ambassador Lwaxana Troi (portrayed by Majel Barrett), and deceased human Starfleet officer Lt. Ian Andrew Troi (portrayed by Amick Byram). An older sister, Kestra, died in a drowning accident during Deanna's infancy. Although Deanna Troi has little exposure to Earth culture, she attended Starfleet Academy from 2355 to 2359, as well as the University on Betazed, and earned an advanced degree in psychology.
Deanna Troi serves as the ship's counselor aboard the Starfleet starships USS Enterprise (NCC-1701-D) and Enterprise-E under the command of Captain Jean-Luc Picard. In Star Trek: Nemesis, Troi leaves the Enterprise with her new husband William Riker, who has just been promoted to captain of the USS Titan, assuming the newly created position of Diplomatic Officer (along with maintaining her original occupation of counselor). Troi's empathic abilities prove key to main shows, and another popular area is her relationships and sexuality. In "The Child", she gives birth to an alien child.
The Betazoid race has telepathic abilities. Due to her half-human heritage, Troi has only partial telepathic abilities and as a result is more of an empath with clairsentience. In Star Trek: Nemesis, Troi has expanded her empathic abilities as she is able to connect to another psychic and follow that empathic bond to its source. In this instance, her ability enables Enterprise-E to target and hit the Romulan vessel Scimitar, despite the fact that it is cloaked. She is also able to communicate telepathically with her mother and other telepathic Betazoids or races with sufficient aptitude. There are several species who are resistant to the telepathy and empathy of Betazoids such as the Ferengi, the Breen and the Ulians.
Early in the series, Troi finds herself working with a former lover, the newly assigned first officer to USS Enterprise, Commander William Riker. In season one, she meets a potential spouse in "Haven". In later episodes, Troi has romantic involvements with several others, including a brief relationship with Klingon Starfleet officer Lieutenant Worf. A major exploration of their relationship begins with "Parallels", in which Worf encounters parallel universes where they are married with children. Another episode that explores a Troi-Worf relationship is "Eye of the Beholder". However, in both cases they are not revealed to be dating aboard the "real" ship, although both episodes are oriented towards exploring this concept. In "All Good Things...", the beginnings of real-world relationship are briefly explored, though this is abruptly dropped as Worf explores other love interests in Star Trek: Deep Space Nine, and Troi's romantic relationship with Riker is rekindled through the Next Generation films.
As a main cast member, Troi appears in nearly every TNG episode, though particular episodes, starting with "The Child", feature her as the primary protagonist. Her name is included in the show title "Ménage à Troi", which is oriented towards an adventure she and her mother have (Besides Data and Q, this is one of the few cases where a character's name is in the episode title). Other episodes principally about Troi include: "Face of the Enemy", "Man of the People", "Violations", and "Night Terrors".
She is addressed in various ways by fellow officers. Captain Picard calls her "Counselor", but when he is concerned about her, or in emergencies, he calls her "Deanna." Picard also refers to her as "Commander" in the pilot episode, Encounter at Farpoint, which is consistent with her uniform's rank pips. Riker addresses her as "Lieutenant" a single time in the pilot episode; her service rank is not referred to again for several seasons. Doctor Crusher (one of her most noted female friends) usually calls her "Troi". Data very rarely calls her by her first name, usually calling her "Counselor Troi." Depending on the situation, Commander Riker will call her "Deanna" or "Imzadi", which means "beloved" in the Betazoid language.
In several episodes, Troi falls victim to aliens. In an episode of Season four ("Clues"), the Enterprise’s crew lose a day's memory. As events unfold, Troi is taken over by an entity in order to communicate with the crew. She temporarily gains "super-human" strength and effortlessly tosses Worf across the bridge, breaking his wrist. In the season five episode, "Violations", the Enterprise encounters an alien species who are telepathic and specialize in being able to bring back lost memories. One of the aliens mentally assaults Deanna and also tries to physically assault her in her quarters. She is saved by Worf and one of his security teams. In the film, Star Trek Nemesis, she is mentally violated by Shinzon's viceroy, who is also telepathic. This occurs in her quarters when she is with her new husband, Commander Riker; it also occurs in the Star Trek: Nemesis bonus deleted scenes, where she is attacked in the turbolift. She eventually is able to turn the tables on the viceroy using the same connection.
Troi is an avid connoisseur of chocolate, a fact that is significant in multiple episodes, including one in which she tells Commander Riker how to properly enjoy eating it. In the episode "Remember Me", Beverly Crusher briefly describes Troi to Captain Picard to jog his memory and mentions that she "loves chocolate". She is known for ordering chocolate-flavored desserts in Ten-Forward, and her love for desserts is a common point of dialogue in many shows. She talks about this with a visiting-alien ambassador in "Liaisons", who takes up her love for desserts as in their culture they do not have this type of food.
Dream-themed episodes include "Phantasms", where Deanna appears as cake in Data's dream and in "Night Terrors", her dreams help save the ship. The dreams a suitor thinks he is having about her in "Haven" become a major plot point in that episode.
Development and castingEdit
Marina Sirtis at first read for the role that would become Tasha Yar in 1986. She had, in total, five readings all with Gene Roddenberry and other executives. It has been noted that Roddenberry took a liking to her almost immediately. Denise Crosby, who eventually won the role of Tasha, auditioned for the role of Deanna Troi. It was said that Marina Sirtis had a more "exotic" feel about her.
She was just about to return home, in debt and jobless, when she received the phone call alerting her that she had the role of Deanna Troi. She stated that if it had been an hour later she would have missed that call and been on her way to England. Sirtis' US visa was expiring that day and, if she had stayed any longer, she could have run into legal trouble.
For Sirtis, Star Trek was her first big break. Prior to Deanna Troi, her acting career was going nowhere: "What they told us about The Next Generation when we first started was that we were guaranteed twenty-six episodes. So that was the longest job I've ever had." She knew little about the Star Trek franchise and at first just thought of it as a good means to pay her bills.
Initially, Sirtis/Troi was planned as the eye-candy of the show.[dubious ] Gene Roddenberry intended her to have four breasts, before his wife told him this was a poor idea. Prior to filming, Sirtis was told to lose 5 pounds (2.3 kg; 0.36 st), but thought to herself that she had to drop even more, and was often wearing plunging necklines and form-fitting dresses. After six years, the producers decided to drop the "sexy and brainless" Troi and make her a stronger character:
"I was thrilled when I got my regulation Starfleet uniform... it covered up my cleavage and I got all my brains back, because when you have cleavage you can't have brains in Hollywood... I was allowed to do things that I hadn't been allowed to do for five or six years. I went on away teams, I was in charge of staff, I had my pips back, I had phasers, I had all the equipment again, and it was fabulous. I was absolutely thrilled."
One reviewer compared her to Doctor McCoy from the older Star Trek television series. In 2018, CBR ranked Counselor Troi as the 25th best Starfleet character of Star Trek, in 2018; they note her role as an empath aboard Enterprise 1701-D. In 2017, IndieWire ranked Troi as the 9th best character on Star Trek: The Next Generation.
Besides being a regular in The Next Generation and its films, the Deanna Troi character appears in three episodes of Star Trek: Voyager ("Pathfinder", "Inside Man", and "Life Line") together with Reginald Barclay, and also in the final episode of Star Trek: Enterprise with William Riker. The final episode of Enterprise was also Troi and Riker's last appearance, until it was announced that she's also set to return in Star Trek: Picard.

"She landed a guest role on the series Hunter. Other small television roles followed, but no steady work came her way during her short stay. Just before she was to return home – broke, credit cards "maxed out," and depressed – Sirtis auditioned for the role of the chief security officer aboard the USS Enterprise, Lieutenant Macha Hernandez (later changed to Natasha Yar)."
