Melora Pazlar (Memory Alpha article)	Daphne Ashbrook (Memory Alpha article)	Melora (DS9)
Melora Pazlar is a female Elaysian, a species from a planet where gravity is weaker than on most other planets. As of stardate 47229.1, she was an Ensign in Starfleet, and a cartographer. Pazlar came to the station prior to a mapping mission to the Gamma Quadrant. Because the gravity on DS9 was too strong for her, she had to rely on either a wheelchair, or an exoskeletal network of flexible metal beams worn over her body to help her move around the station. Doctor Julian Bashir devised a treatment to help her walk like the other humanoids on the station. Pazlar started the treatment, but when she realized that she wouldn't be able to enjoy low-gravity environments any more, she decided to discontinue the process. The character was originally developed to be the regular science officer on the series. However, logistics made it difficult to use the effects required on a regular basis, and the character was used as a guest appearance instead.

However, Pardek has fallen out of favor in the Romulan political arena, and seeking a way back into Proconsul Neral's good graces, betrays Spock and the entire Romulan Underground movement to Commander Sela.
Parem (Memory Alpha article)	Brian Cousins (Memory Alpha article)	The Next Phase (TNG)
Romulan officer who, like Geordi La Forge and Ro Laren, was rendered invisible and "out of phase" by chroniton particles from an experimental Romulan interphase generator gone amok.

La Forge surprises him with a body slam that sends him through the bulkhead and careening into outer space ... forever.
Patahk (Memory Alpha article)	Steve Rankin (Memory Alpha article)	The Enemy (TNG)
Romulan officer and one of two survivors of the crash of the Pi, a small Romulan ship, on the surface of Galorndon Core. He's rescued by an Enterprise-D away team and transported to Sickbay. Dr. Beverly Crusher diagnoses him with cell damage to vital areas, necessitating a transfusion of compatible ribosomes for him to recover. Worf is the only crew member who can make such a donation, but he refuses. In turn, Patahk says he would rather die than "pollute his body with Klingon filth." He succumbs soon afterward.

A Flaxian merchant who visited Starbase Deep Space 9 in 2371. He dealt in fine wares, mostly fabrics and fragrances.

He was hired by the Tal Shiar, at Enabran Tain's behest, to kill Elim Garak. Retaya intended to use a gaseous mixture of fragrances to trigger a fatal heart attack, but never got the chance because Garak blew up his own shop.

A female Tal Shiar agent in 2371 who admitted that a Flaxian, Retaya, was killed for crimes against the Romulan Star Empire, and said that the Tal Shiar had been looking for him for nearly a year. She knew that a Cardassian named "Mr. Garak" lived on Starbase Deep Space 9, but "guessed" that he was a "cobbler" by profession. When Commander Benjamin Sisko corrected her that Garak was a tailor, she said she'd correct her records … if Garak was still alive. When Sisko said he was, the agent was noticeably silent for a beat. (Costuming Note: This character debuted the new Tal Shiar uniform. Her rank insignia was a single arrowhead and a single concave crescent — the same as Rakal's from TNG's "Face of the Enemy," indicating that she may have been a major.)
Romulan Commander (Memory Alpha article)	James Doohan (Memory Alpha article)	The Survivor (TAS)
He commanded two D7-class battle cruisers in 2269. When he caught the Enterprise in the Romulan Neutral Zone, he noted that Captain James T. Kirk had a propensity for trespassing there and demanded the Enterprise's surrender. Kirk refused, claiming that the commander had lured the Enterprise into the Neutral Zone (a treaty violation) through the use of a Vendorian (also a treaty violation). After a brief battle, the commander withdrew his ships. (In his novelization of "The Survivor" in Star Trek Log Two, Alan Dean Foster named this character "Larus.") (Uniform Note: This Romulan Commander wore a different uniform than the Romulans from TOS. He was only visible from the shoulders upward, but the uniform was a light green cloak over a dark green shirt.)
Romulan Commander (Memory Alpha article)	Mark Lenard (Memory Alpha article)	Balance of Terror (TOS)
He commanded the Praetor's flagship Bird-of-Prey in destructive attacks against Federation outposts 2, 3, 4 and 8 along the Romulan Neutral Zone in 2266. His mission was to test Starfleet defenses after more than a century of no contact, as well as the effectiveness of the Romulans' new cloaking system and plasma weapon. His was the first Romulan face ever "officially" seen by Starfleet officers. He proved to be a match for Captain James T. Kirk, even though he privately detested provoking the Federation and risking another war for the Romulan Star Empire. When Kirk finally defeated him, he refuseed any rescue attempt because it was not the "Romulan way." Instead, he self-destructed his own ship.
Romulan Commander (Memory Alpha article)	Joanne Linville (Memory Alpha article)	The Enterprise Incident (TOS)
She commanded three Romulan warships that captured the Enterprise after it "strayed" into Romulan space in 2269. She was also responsible for the loss of the "new and improved" cloaking device after Kirk and Spock "played" her. She ended up aboard the Enterprise as a prisoner/guest. Although not named in the script or the finished episode, she "whispered" her name to Spock during his time aboard her flagship.
Romulan Commander (Memory Alpha article)	J. Patrick McCormack (Memory Alpha article)	NEM
He stands before the Imperial Senate and quietly acquiesces, "Yes, sir," when Praetor Hiren refuses to pursue an alliance with Shinzon of Remus. (Noncanon: The movie novelization names his character "Bezor.")

In the Imperial Senate, he ardently proposes an alliance between the Romulan military and Shinzon of Remus. He says that with their combined strength, not even the Federation would dare oppose the Star Empire.(Noncanon: The movie novelization names his character "Talik.")
Romulan Commander (Memory Alpha article)	Maurice Roëves (Memory Alpha article)	The Chase (TNG)
He commanded a Romulan Warbird that, while cloaked, followed the Enterprise-D and two Cardassian warships to a planet in the Vilmoran system. On the surface, he witnessed the holographic message from a humanoid who claimed that her race seeded the primordial oceans of many worlds with ancient DNA, thereby suggesting that humans, Klingons, Vulcans/Romulans and Cardassians are all related. Before leaving the planet, the Commander contacted Picard and admitted that, perhaps, their people were not so dissimilar after all. (Costuming Note: Despite the introduction of Romulan rank insignia only a few episodes earlier, he wore none on his collar.)
Romulan Commander (Memory Alpha article)	Lou Scheimer (Memory Alpha article)	The Practical Joker (TAS)
In 2269, he commanded three D7-class battle cruisers, which hid behind a Type-4 asteroid and ambushed the Enterprise as she approached. The commander claimed that the Enterprise had trespassed into Romulan territory and that he was forced to defend it. He also said that the invasion of Romulan territory was punishable by death. Later, when the Enterprise released a larger decoy balloon of itself, the commander pursued it at attack speed. After destroying it easily and learning that he'd been tricked, he was so furious that he followed the real Enterprise into Federation territory, hoping to destroy it. In so doing, he entered a strange energy field in space, and when his ships' instrumentation was rendered useless, he decided to vacate the field before his ships broke up. He ordered a course set for home. However, brief passage through the field caused his food synthesizers to malfunction. He and his crew were "knee deep in desserts" when last heard from. (Uniform Note: This Romulan Commander wore a different, but more elaborate, uniform than the Romulans from TOS and the Romulan Commander from "The Survivor." His was a red unitard with turtleneck, with the long sleeves ending in "jagged" white with a single black stripe; a scaly-silver short-sleeve overshirt; silver boots; a black belt with gold buckle; and a white sash draped from the left shoulder across the chest.)

First, however, they plan to destroy Deep Space 9.

Picard and the USS Enterprise-E travel to Romulus to meet Shinzon and investigate his peace overture; Shinzon reveals his identity and origins to Picard. However, the peace overture is part of a plan to lure Picard to Romulus; the cloning process that created Shinzon is killing him, and he requires an infusion of Picard's DNA to stay alive. Simultaneously, Shinzon plans to use a thalaron radiation weapon aboard his ship, the Scimitar, to destroy all life on Earth. The Scimitar attacks and severely damages the Enterprise.

When the landing party to Gamma Hydra IV is stricken with advanced aging, Stocker compels Spock to convene an extraordinary competency hearing for Kirk.

If found, then it would threaten the legitimacy of the Vulcan High Command and have an enormous impact on the Vulcan people.

Syrran was killed soon afterward by an electrical discharge during a sand-fire storm, but before he died, he transferred Surak's katra to Archer.
