Unnamed Romulan military personnel ( 23rd century ) The following is a list of unnamed Romulan military personnel who lived during the 23rd century . 2266 . Centurion . The Romulan centurion served aboard the Praetor ' s flagship that attacked several Federation outposts along the Romulan Neutral Zone in 2266 . He was a close friend of his commander ( " see entry below " ) , and served with him in many campaigns . He believed in the right of the Romulan Empire to expand by use of any means necessary , including war . He was of the old ways , where you did not question the Praetor , but gave obedience . These beliefs were not entirely held by his commander . He was killed in battle with the ; he had pushed his commander to safety and was mortally injured by some falling debris in the control room . After he succumbed shortly thereafter , his body , and some of the ship ' s debris , was later jettisoned in an attempt to deceive the " Enterprise " into believing the ship was destroyed . ( ) Commander 1 . Around stardate 1709 , a Romulan commander piloted a on a mission testing a cloaking device , and a new plasma weapon that destroyed Federation outposts along the Romulan Neutral Zone . A veteran of countless military campaigns , he was an atypical Romulan commander who questioned the ethics of his mission and was wary of war . He believed that enough lives had been sacrificed for the Romulan quest for conquest . He engaged commanding officer James T . Kirk in a deadly game of cat and mouse . At first , the Romulan commander tried to return to Romulus to deliver the information on the new weapon . However , he ordered for the Bird - of - Prey to turn and fight when the " Enterprise " intercepted the vessel . When his ship was disabled by the " Enterprise " , he destroyed his own craft , rather than be captured . He told Kirk that he admired him and that they were alike , and could have been friends in another reality . ( ) Background information . This " Romulan commander " was played by actor Mark Lenard . This character is often credited with being the first Romulan seen on " Star Trek " , even though technically Decius was seen first , albeit with a helmet covering up his ears . Lenard ' s character was the first Romulan fully seen with Vulcan - type ears . In the revised final draft script of " Balance of Terror " , the Romulan commander was described thus ; " " The Commander – tall , graying , tired - looking – wears a white uniform that distinguishes him from the other members of the crew . He wears no helmet – has ears like Spock . " " A runner - up for this role was Lawrence Montaigne , who was eventually cast as Decius . For the role of the commander , he read with TOS Casting Director Joseph D ' Agosta . However , understanding and relating to the part meanwhile proved too difficult for Montaigne . " " The casting director said that ' the character was the Commander of an intergalactic space ship that was about to engage the " Enterprise " in battle . ' Yeah , sure , " " the actor remembered . " " So I read , thanked everyone , and split . " " A few days later , Montaigne received the news , via a phone call from his agent , that he hadn ' t been cast as the commander . He was disappointed by the news but could understand why he hadn ' t been chosen for the part , given his difficulty of comprehending it . When his agent told him Mark Lenard had been selected instead , Montaigne , aware of Lenard ' s work , begrudgingly accepted Lenard would make a much better Romulan commander than he himself would . During the same phone call , however , Montaigne also learned he had won the role of Decius . ( " Prologue " , " A Vulcan Odyssey " ) Lenard ' s performance as the Romulan commander impressed the producers , and he was therefore added to a short - list of possible replacements for Leonard Nimoy to play Spock . The popularity of the Romulan commander also led to Lenard being recast later in the series , as Spock ' s father , Sarek . A running joke among the " Star Trek " production staff was that the main reason why Spock looked so surprised , when first seeing the Romulan Commander in " Balance of Terror " , was because Spock ' s father was commanding the Romulan ship . Apocrypha . In William Shatner ' s novel " The Return " , the commander ' s House , one of the oldest and most esteemed on Romulus , fell into disgrace after this failure , and his granddaughter was responsible for resurrecting Kirk , which she did with the intention of killing him and restoring the family ' s standing . In the " " short novel " A Less Perfect Union " ( set in an alternate timeline in which , firstly , an attack on Starfleet , perpetrated by Terra Prime in the episode , succeeded , Earth then went into isolation , and the Federation was never formed ) , the commander impersonated Sarek in order to disrupt a 2264 diplomatic conference . As he looked so much like Sarek , no disguise was necessary to pull it off , and he openly wondered if the two shared common ancestry from before the Vulcan - Romulan split . The comic " The Khitomer Conflict , Part 1 " depicts a character named L ' Nar in the alternate reality , who may or may not be the same character . Crewman 1 .

She wanted Spock to serve at her side and take the " Enterprise " to Romulus . Spock reacted favorably to her advances .
