Character	Actor	Appearances	Description
Tactics Officer	Peter Parros	A Matter of Honor (TNG)	Klingon officer serving aboard the IKS Pagh in 2365. He escorted William Riker to see Captain Kargan, but kept looking askance at the commander because he'd never seen a human before. Later, in the mess hall, he also admitted that he never knew humans had a sense of humor. Regarding his family, his mother was still living, but his father was killed in battle at Tranome Sar.
Tahna Los	Jeffrey Nordling	Past Prologue (DS9)	Bajoran terrorist who comes aboard Deep Space Nine asking for asylum only to escape Cardassian pursuit and begin work on his next attack
Taibak	John Fleck	The Mind's Eye (TNG)	Romulan officer and scientist who successfully "conditioned" Geordi La Forge to kill Klingon governor Vagh of Krios, although the assassination failed. Taibak served aboard Commander Sela's Warbird in late 2367, and his "brainwashing" efforts were part of a larger Romulan plot to disrupt the alliance between the Federation and the Klingon Empire.
Enabran Tain	Paul Dooley	The Wire (DS9) recurring thereafter	Former head of the Obsidian Order and the father of Elim Garak
Juliana Tainer	Fionnula Flanagan	Inheritance (TNG)	A Soong-type android created in the image of Noonien Soong's dying wife, Juliana Soong; at Juliana's death, Noonien transferred his wife's consciousness into the android who awoke believing she was Juliana Soong; later left Noonien, married Pran Tainer and took up residence on planet Atrea IV
Tal	Jack Donner	The Enterprise Incident (TOS)	Subcommander of the Romulan fleet that brackets the Enterprise when she "strays" into Romulan space. After Captain Kirk steals the cloaking device and beams back aboard the Enterprise, Tal sets off in pursuit. When his Commander orders him to destroy the Federation starship, he attempts to comply, but fails because Mr. Scott managed to successfully install the cloaking device and render the Enterprise "invisible."
Tal Celes	Zoe McLellan	The Haunting of Deck Twelve (VOY) Good Shepherd (VOY)	Bajoran sensor analyst on Voyager, assigned to Astrometrics. Despite her evident insecurity, she later demonstrated bravery, refusing to abandon Janeway in danger. ("Good Shepherd")
Taleen	Nancy Youngblut	Displaced (VOY)	Nyrian who explained a new customized habitat to the Voyager crew, as part of the Nyrian's forced relocation scam.
Talok	Todd Stashwick	Kir'Shara (ENT)	Romulan agent who posed as a Vulcan major for many years, working with the radical Administrator V'Las of the Vulcan High Command to force reunification between their two peoples. A "very long time" before 2154, Talok served under T'Pol in the Tomed mission. In 2154, V'Las ordered Talok to eradicate the remaining Syrrannites. Talok tracked down Jonathan Archer in Vulcan's Forge and attempted to take the Kir'Shara, but Archer escaped. After V'Las was removed and the Vulcan High Command disbanded, Talok's position was compromised and he was forced to leave Vulcan.[1]
Tarcassian Razor Beast	None (Only discussed, never seen.)	Imaginary Friend, Rascals (TNG)	Imaginary friend from the childhood of the enigmatic female El-Aurian bartender Guinan, who ran Ten Forward, the lounge aboard the USS Enterprise-D. The Tarcassian razor beast was a winged, furry animal noted for its spiny wings, and its loping way of locomotion. When Guinan was troubled, she'd talk to it, and she enjoyed imagining that she was curling up on its warm belly.
Taris	Carolyn Seymour	Contagion (TNG)	Romulan subcommander of the IRW Haakona. She spotted and chased the USS Yamato NCC-71807 throughout the Romulan Neutral Zone before finally witnessing its destruction due to systems failures. When confronted almost immediately by the Enterprise-D, she denies any involvement in the Yamato's destruction and orders Captain Jean-Luc Picard to leave the Neutral Zone. Later, at Iconia, her "excuse" for having followed the Enterprise-D was to claim the planet for the Romulan Star Empire, but when Commander William Riker points out that neither side can claim anything in the Neutral Zone, she again orders the starship to leave, or else she'll destroy it and the Away Team on Iconia. In truth, Taris is deeply frustrated; earlier, the Haakona tapped into the Yamato's log as it was being transmitted to the Enterprise-D, and has now become crippled by Iconian "malware." When Picard steps onto her ship from the Iconian portal, she blames him for sabotage, but seems satisfied that he'll die when her ship autodestructs. Picard, however, is beamed back to the Enterprise-D, and Riker shares the "memory wipe" solution that Geordi La Forge developed with Taris.[2]
Taurik	Alexander Enberg	Lower Decks (TNG)	Vulcan ensign and junior engineer aboard the Enterprise-D. His ideas for improving warp drive operation rankle La Forge at first, but La Forge later sees the merit in Taurik's suggestions and invites him to help test them.

Tebok	Marc Alaimo	The Neutral Zone (TNG)	Romulan commander who, in 2364, made the first "official" contact with the Federation after more than 53 years of Romulan isolation. He was primarily charged with discovering why several Romulan outposts along the Neutral Zone had disappeared, but the re-emergence was also orchestrated to show off the Romulans' massive new D'Deridex class "warbird" starships. Tebok ominously proclaimed "we are back" to Captain Picard.
Temarek	Elkanah J. Burns	The Vengeance Factor (TNG)	Temarek was an Acamarian Gatherer and a member of Clan Lornak. During treaty negotiations in 2366, he discovered the corpse of Volnoth, who was killed by Sovereign Marouk's servant Yuta because of ancient clan rivalries.
Ten Forward Waiter	Randy James	The Outrageous Okona (TNG) recurring thereafter	Uncredited human male who worked in Ten Forward in 2365. He served a drink to a Vulcan science officer while Thadiun Okona was beamed aboard (The Outrageous Okona), served drinks to several people in Ten Forward when Data had a conversation with Kareen Brianon in the bar (The Schizoid Man), served a variety of Klingon food to Commander Riker, who was assigned to serve as first officer on the Klingon Bird-of-Prey IKS Pagh (A Matter Of Honor) and was also working in Ten Forward when Riker tried to show Wesley Crusher how to flirt by "playing" with Guinan and when Riker had a date with a female crewmember (The Dauphin; Pen Pals).
Clark Terrell	Paul Winfield	WOK	Captain of the starship Reliant. Controlled by Khan Noonien Singh via a Ceti eel, forcing him to nearly kill Admiral Kirk. Rather than murder a fellow Starfleet officer, he committed suicide. Terrell is also featured in the Star Trek Vanguard book series, along with Dr. Carol Marcus. Together they begin work on the foundations of Project Genesis.

Thei	Anthony James	The Neutral Zone (TNG)	Romulan subcommander and first officer aboard Commander Tebok's Warbird. With Tebok's permission, he agrees that the Romulans and the Federation should share information regarding the mysterious disappearances of outposts on both sides of the Neutral Zone.
Thelev	William O'Connell	Journey to Babel (TOS)	An Orion agent posing as a member of the Andorian delegation to the 2267 "Babel" conference. His mission is to create mutual suspicion among the Federation ambassadors aboard the Enterprise. To that end, he kills Tellarite ambassador Gav and tries to frame Vulcan ambassador Sarek for the crime. Later, he attacks Captain Kirk before being caught and revealed as an Orion. To prevent himself from revealing any further information, he commits suicide by taking poison.

Toddman	Leon Russom	The Die Is Cast (DS9)	Starfleet vice admiral at Starfleet Security in 2371. After Enabran Tain launched a joint Obsidian Order/Tal Shiar attack on the Founders' homeworld, Toddman ordered Commander Benjamin Sisko to evacuate Starbase Deep Space Nine of all nonessential personnel and put the USS Defiant NX-74205 on standby alert. He believed that when the Jem'Hadar inevitably counterattacked, they wouldn't be too particular about their targets. Toddman denied Sisko permission to take the Defiant into the Gamma Quadrant and look for Odo; Sisko's top priority was to guard Bajor. Later, after learning that Sisko went anyway, Toddman decided to forgo any courts-martial, but, with tongue in cheek, promised to either prosecute or promote Sisko if he pulled a stunt like that again.[3]

Toreth	Carolyn Seymour	Face of the Enemy (TNG)	Romulan commander of the IRW Khazara. She received the Sotarek Citation for prevailing in a surprise battle with the Klingons. She had no love for the Tal Shiar, particularly because they dragged her father (possibly Commander Konsab) out of his home in the middle of the night, merely for speaking his mind.[4]
Torg	Stephen Liska	SFS	Klingon officer aboard Commander Kruge's Bird-of-Prey. He and his boarding party are killed when the Enterprise's self-destruct sequence destroys the Federation starship. He may have been Kruge's first officer, as he assumed the command chair when Kruge was on the surface of Genesis.

Trevean	Michael Sarrazin	The Quickening (DS9)	Native of the planet Teplan in the Gamma Quadrant who "aided" those on his planet infected with a terminal, painful, and slow-acting disease known as the Teplan Blight by administering them toxic herbs, which killed the patients without pain

Vagh	Edward Wiley	The Mind's Eye (TNG)	Klingon governor of Krios in late 2367. He accused Starfleet of supplying weapons to Kriosian rebels, who sought to gain their planet's independence from the Klingon Empire. However, Data and Geordi La Forge discovered that the weapons actually had been constructed and distributed by the Romulans. While Vagh was aboard the Enterprise-D to witness the crew's investigation into the matter, he was nearly killed by La Forge, who had been "conditioned" by the Romulans to shoot him.
Valeris	Kim Cattrall	TUC	Starfleet lieutenant and Enterprise-A helmsman who was complicit in the assassination of Klingon chancellor Gorkon. Kim Cattrall chose the Eris element of the character's name, for the Greek goddess of strife, which was Vulcanised by the addition of the "Val" at the behest of director Nicholas Meyer.[8]
Valkris	Catherine Shirriff	SFS	An elegant Klingon agent who stole a copy of Admiral Kirk's summary of the Genesis Project. She booked passage on the Merchantman to rendezvous with a Bird-of-Prey commanded by Kruge, to whom she presented the information. When Kruge found out that she had watched the summary herself, he destroyed the Merchantman. Valkris and Kruge may have been lovers, as her final endearment to him was, "Success, my lord, and my love."
Varel	Susanna Thompson	The Next Phase (TNG)	Romulan officer aboard Mirok's ship who conspires with him to destroy the Enterprise-D. They decide to send a muon feedback wave along the Enterprise's power transfer beam.

Vash	Jennifer Hetrick	Captain's Holiday (TNG), Qpid (TNG), Q-Less (DS9)	An antiquarian, with a habit of pursuing artifacts with unethical zeal as a profiteer, who falls in love with Picard. She first appeared in the Star Trek: The Next Generation episode "Captain's Holiday", in which Jean-Luc Picard vacationed on Risa. Vash had discovered the Tox Uthat, an artifact thieves were determined to take from her; with Picard's help, the thieves were thwarted. During this adventure, she and Picard fell in love. They met up again in the episode "Qpid", in which Vash became annoyed on finding that none of Picard's senior staff had even heard of her, despite his explanation that he is "a very private man." Q abducted her and the Enterprise senior staff, casting them into a Robin Hood scenario, with Picard playing Robin Hood and Vash as Maid Marian. The result was Vash leaving with Q to the Gamma Quadrant, to scour archaeological sites there. Vash reappeared in the Star Trek: Deep Space Nine episode "Q-Less" two years later, in which episode she mistook for an artifact an "egg", which subsequently hatched as a lifeform at the end of the episode. In 2017, CBR ranked Vash the 11th "fiercest" female character of the Star Trek universe.[9]

Vekma	Laura Drake	A Matter of Honor (TNG)	Klingon officer serving aboard the IKS Pagh in 2365. She said that Commander William Riker wasn't very attractive, but that she would "have him".

Velal	Stephen Yoakam	Inter Arma Enim Silent Leges (DS9) recurring thereafter	Romulan subcommander who was to replace Senator Kimara Cretak at a weekly Deep Space Nine meeting while she attended a conference on Romulus in 2375. Shortly afterward, Velal was promoted to general. After all Federation and Romulan ships were rendered powerless by a Breen energy dissipation weapon, Velal was genuinely dismayed to learn that only the Klingons stood between the alliance and total defeat at the hands of the Dominion. Near the end of the war, when the Dominion pulled all its forces back to Cardassian space, Velal's instinct was to merely "contain them within their perimeter" instead of attacking. He changed his mind when Vice Admiral William Ross, Captain Benjamin Sisko and General Martok decide on the latter.[10]
Verad	John Glover	Invasive procedures (DS9)	Verad was an unjoined Trill and failed host candidate who briefly stole the Dax symbiont from Jadzia Dax in 2370.
V'Ger	None	TMP	A sentient being that evolved from Voyager 6, a fictitious space probe (inspired by the real life Voyager program) from the 20th century that vanished into a black hole and was given life by a race of living machines. The story of V'Ger and its return to Earth to seek "the creator" forms the plot for the first feature film in the Star Trek series, Star Trek: The Motion Picture. V'Ger's story is also expanded upon in the novelization, and various novels, most notably William Shatner's The Return. Some novels, comics, and videogames have strongly implied that V'Ger was the progenitor of the Borg, or was encountered by the Borg culture's direct ancestors. The Gene Roddenberry-authored novelization of the movie consistently named "V'Ger" with the spelling "Vejur" throughout the novelization's text,[11] to preserve the surprise ending.
Jason Vigo	Ken Olandt	Bloodlines (TNG)	Bok, a Ferengi, altered Vigo's DNA to make him appear to be the son of Enterprise Captain Jean-Luc Picard. Bok used Vigo as bait as part of a plan to avenge his son's death at the hand of Picard.

In 2152, she infiltrated the government of Mazar to expose corrupt officials and had to be extracted by Enterprise NX-01.
V'Las	Robert Foxworth	The Forge (ENT) recurring thereafter	Vulcan administrator of the Vulcan High Command. Addressed as "excellency." Until he was removed as leader in 2154, he pursued a radical agenda that was contrary to the true teachings of Surak. He militarized the Vulcan fleet and suppressed the practice of mind melds. He was secretly working with a Romulan agent, Talok, to force the reunification of their peoples. When V'Las tried to start a war with the Andorian Imperial Guard, one of his ministers, Kuvak, shot (stunned) him, thus stopping the conflict and disbanding the Vulcan High Command.
Volnoth	Marc Lawrence	The Vengeance Factor (TNG)	Volnoth was an Acamarian Gatherer and a member of Clan Lornak. During negotiations with the Gatherer's leader Chorgan in 2366, he was killed by Sovereign Marouk's servant Yuta because of ancient clan rivalries.
Vorik	Alexander Enberg	Fair Trade (VOY) recurring thereafter	Starfleet ensign and Vulcan engineer aboard the Starship Voyager. He bears a striking resemblance to Ensign Taurik, another Vulcan engineer who served on the Enterprise-D.
Vosk	Jack Gwaltney	Storm Front (ENT)	Alien enemy in Agent Daniels' Temporal Cold War who joins with the Nazis during World War II, enabling them to defeat the Allies.
Vreenak	Stephen McHattie	In the Pale Moonlight (DS9)	A key member of the Romulan Senate from 2360 to 2374, Vice-Chairman of the Tal Shiar, secretary of the War Plans Council, and one of Proconsul Neral's most trusted advisors. Ardently pro-Dominion, Vreenak was key in negotiating the non-aggression pact between the Romulan Star Empire and the Dominion in late 2373. However, his death caused the Romulans to join the Dominion War on the side of the Federation-Klingon alliance.
