Romulan

The Romulans were devised for the episode "Balance of Terror". In 2014, "Balance of Terror" was rated the best episode in the franchise by Io9.[1]

The Romulans were reused for the second-season episode "The Deadly Years" and the third-season episode "The Enterprise Incident".

After the launch of Star Trek: The Next Generation in 1987, the show's writers introduced the Romulans in the final episode of the first season, "The Neutral Zone", which aired in the U.S. in May 1988.[2] The episode was written by Maurice Hurley, who later acknowledged rushing it, putting together a script in a day and a half.[2] In the episode, which is set in the year 2364, the Starfleet ship USS Enterprise-D—whose crew are the series' main protagonists—responds to the disappearance of Federation colonies along the Neutral Zone, fearing that it reflects growing Romulan activity in the region. Investigating, the Enterprise crew encounter a Romulan spaceship; it is stated that this is the first encounter between the two peoples for 53 years. The Romulans reveal that they have had colonies destroyed on their side of the border too, and the two species agree to share information on the issue in future.[3] In later episodes it is revealed that these colonies were destroyed by a previously unknown species, the Borg, whom the show's writers had devised as a new alien antagonist following dissatisfaction with their previous attempt, the Ferengi.[4] Initial thoughts by the script-writers had proposed a multi-episode storyline in which the Federation and Romulan governments would co-operate to fight the Borg; ultimately only certain elements of this idea entered "The Neutral Zone" and the Borg would be introduced not in the first season, but in the second-season episode "Q Who".[4]

For The Next Generation, a new crest was designed for the Romulan Empire, featuring a bird of prey clutching the twin planets of Romulus and Remus.[4]

New costumes were designed for the actors playing Romulans, created by the show's costume designer William Theiss.[5] The newly designed Romulan ship that appeared in "The Neutral Zone" was built as a miniature model by Greg Jein.[4] The ship featured a newly designed Romulan crest, featuring a stylised bird of prey clutching two planets, Romulus and Remus, in its claws.[4] Later in the series, this ship type would be explicitly referred to as a "warbird".[4] In 1989, AMT released a plastic kit of the vessel, alongside other kits for a Ferengi ship and a Klingon bird of prey vessel.[4]

The Romulans were re-used for the second-season episode "Contagion", written by Steve Gerber and Beth Woods and first aired in March 1989. In this episode, the Enterprise-D entered the Neutral Zone to answer a distress call and ends up in conflict with a Romulan vessel, with both spaceships being disabled by an alien computer virus.[6] "Contagion" was the first episode in the Star Trek franchise in which the Romulan ship was given a name, in this case the Haakona.[7] In the third-season episode "The Enemy", written by David Kemper and Michael Piller and first screened in November 1989, the Enterprise-D is depicted rescuing a crashed Romulan ship.[8] The episode introduced the Romulan character Tomalak, played by Andreas Katsulas, who would reappear in three further Next Generation episodes.[8] It also further established the idea of a significant enmity between the Romulans and the Klingons, with the Enterprise's Klingon officer, Worf (Michael Dorn), refusing to donate blood to save the life of an injured Romulan; the scriptwriters had debated whether to include this, with Dorn initially reticent.[8]

Three episodes later, in "The Defector", written by Ronald D. Moore and first screened in January 1990, a Romulan admiral is presented as seeking to defect to the Federation.[9] The episode is the first in the franchise to include images of Romulus itself and introduced the design of a Romulan scout vessel.[9] "The Defector" also includes a reference to the Battle of Cheron, an incident in the 22nd century Earth-Romulan War that was previously mentioned in "Balance of Terror".[9]

For "The Search", the opening two-part episode of the third season of Star Trek: Deep Space Nine, a Romulan link was introduced. The episode, which was written by Ira Steven Behr, Robert Hewitt Wolfe, and Ronald D. Moore, featured the introduction of a new Starfleet ship, the USS Defiant; the scriptwriters included the idea that it had been equipped with a cloaking device by the Romulans in return for intelligence that the Federation gathered on another alien power, the Dominion. A Romulan character, T'Rul (Martha Hackett), was included to oversee the device's use aboard the Defiant.[10] The show's writers had initially planned on including T'Rul as a permanent fixture on the show but decided that she did not offer enough potential for new storylines.[11]

The Romulans were reused later that season in "Visionary", where they are presented as attempting to destroy the Deep Space Nine space station as part of their plan to collapse the nearby wormhole and thus prevent a Dominion invasion of the Alpha Quadrant, the region of space where both the Federation and Romulans reside.[12] Three episodes later, the follow-on episodes "Improbable Cause" and "The Die Is Cast" again featured the Romulans, in this case portraying a joint mission by the Romulan Tal Shiar and Cardassian Obsidian Order to fatally cripple the Dominion by eradicating its leaders, the Founders.[13] For these episodes, new Tal Shiar outfits were designed; Moore related that this was partly his decision, for he "hated, underline hated, the Romulan costumes [introduced in the first season of The Next Generation]. Big shoulder pads, the quilting, I just loathed it."[5] Costume designer Robert Blackman noted that his team created eight new Romulan uniforms, using the same fabric as the old ones but "dyed it down slightly, and we made them much sleeker and a little more menacing".[5]

For the 2009 Star Trek reboot film, the design of the Romulans was significantly altered; although keeping the pointed ears, the V-shaped forehead ridges were removed and various tattoos were added

After Star Trek: Nemesis proved a financial failure and Star Trek: Enterprise was cancelled, the franchise's executive producer Rick Berman and screenwriter Erik Jendresen began developing a new film entitled Star Trek: The Beginning, which was to be set during the 22nd century Earth–Romulan War. The project never materialised.[14] Instead, the decision was made to reboot the series by creating a film using the characters of the original Star Trek series but played by new actors. Putting together a script for the new film, the director J. J. Abrams stated that he wanted Romulans to be the antagonists because they had featured less than the Klingons in the original Star Trek series.[15] The film's writers, Roberto Orci and Alex Kurtzman, thought that it would feel backward to demonize the Klingons as villains again after they had been presented heroically in later Star Trek series; they also wanted to use Spock as a central character in the film and believed that the Romulan presence would continue Spock's story from his last chronological appearance in "Unification".[16]

In the reboot film, titled Star Trek and released in 2009, the planet Romulus is destroyed by a supernova in the year 2387. A Romulan mining ship, the Narada, survives and travels back in time to the 23rd century; its commander, Nero (Eric Bana), is committed to destroying the planet Vulcan to punish Spock for failing to save Romulus. The actors playing Romulans in this film wore three prosthetics applied to their ears and foreheads, while Bana had a fourth prosthetic for the bitemark on his ear that extends to the back of his character's head.[17] The film's Romulans lacked the 'V'-shaped ridges on the foreheads, which had been present in all of their depictions outside the original series. Neville Page wanted to honor that by having Nero's crew ritually scar themselves too, forming keloids reminiscent of the 'V'-ridges. It was abandoned as they did not pursue the idea enough.[18]

Star Trek: Picard centers around Picard's reaction to the destruction of Romulus. The series begins with Picard in self-imposed exile at his French vineyard following his resignation in protest to Starfleet's handling of Romulans and androids. Picard has two live-in Romulans at his estate.[19] At least two groups of Romulans survived: one group formed the Romulan Free State, while the other group was evacuated to the planet of Vashti.
