A female native of Delta IV, she was once involved in a romantic relationship with Willard Decker. As a Starfleet lieutenant, she was assigned to the Enterprise as navigator during the V'ger crisis. She was killed on the Bridge by one of V'ger's probes, but her appearance was later given to another V'ger probe, which was put aboard the Enterprise and assigned to learn about the human "infestation". However, this "Ilia probe" was constructed so perfectly by V'ger that it even contained the real Ilia's memories, which were deeply suppressed. Decker, however, was able to access those memories and establish a personal rapport with the probe. Later, when he learned that V'ger needed a "human element" to reveal its data – and, in so doing, stop its attack on Earth – he input the final code sequence manually, and, together with the Ilia probe, merged with V'ger. Ilia was later listed as "missing" in action.

Later, after he and his wife have a baby girl, Jarok becomes convinced that another war could destroy the Romulan Star Empire. However, the High Command tires of his protests, censures him and sends him off to command some distant sector. When Jarok learns of secret Romulan plans to launch an attack against the Federation from Nelvana III, he steals a scout ship and barely escapes across the Romulan Neutral Zone into Federation space, where he requests asylum aboard the Enterprise-D. He masquerades as Sublieutenant Setal, a logistics clerk, before revealing his true identity. He eventually convinces Picard to cross the Neutral Zone and investigate Nelvana III, but there's nothing there. The Romulan High Command duped Jarok with false intelligence to test his loyalty.

Blood Oath (DS9),
Flashback (VOY)
Legendary Klingon warrior and Dahar Master whose exploits assured him a place in the Hall of Heroes, as told in G'Trok's poem "The Fall of Kang," an epic so important it is required reading at Starfleet Academy. Commander Kang once faced James Kirk in 2269, but later joined him to defeat their true enemy, an energy life form living off their shared hatred when trapped aboard the Enterprise as undying fodder. Captain Kang later squared off against Captain Sulu's USS Excelsior during the tensions preceding the Khitomer Conference in 2293. Kang had already met Curzon Dax by then on the Klingon Korvat colony, when Dax intentionally angered Kang to foster a bond—a calculated risk as he walked out during a long diatribe by the shocked Klingon. The Trill envoy became such a trusted family friend that Kang's firstborn, a boy, was made his godson and named "Dax" in his honor. The boy, of course, was among those later killed in revenge by the marauding Albino and fostered a blood oath of revenge in turn among Kor, Koloth and Dax that was finally carried out in 2370 and led to Dahar Master Kang's death as he struck the death blow on his enemy. He also had defeated T'nag and his army with only colleagues Kor and Koloth, according to Kor's tale in 2372, and later feasted on the leader's heart.
Rayna KapecLouise SorelRequiem for Methuselah (TOS)
Android created in the perfect likeness of a young human woman
KarganChristopher CollinsA Matter of Honor (TNG)
Klingon captain of the IKS Pagh in 2365. He was short, heavyset and demanded strict adherence to his authority. When he learned of the space organism eating away at a small section of the Pagh's hull, and that the Enterprise-D had directed an intense scanning beam at that specific area for two minutes, Kargan believed the Federation starship had landed a first strike against his vessel, so he vowed to attack and destroy the Enterprise-D. He suspected that Commander William Riker, his acting first officer, was complicit in the Enterprise-D's attack, so, to test his loyalty, Kargan demanded to know the surest method of attack against the Federation starship. When Riker refused to break his oath to Starfleet, Kargan relented, knowing at least that Riker wasn't a traitor or a coward. When Riker activated an emergency transponder given to him by Worf, Kargan, believing it was a weapon, demanded that Riker give it to him. Kargan was then beamed aboard the Enterprise-D, and Riker was able to assume command of the Pagh and defuse the brewing battle. Later, when Kargan was returned to the Pagh, Riker refused to resume his station, so Kargan slugged him and ordered him removed from the ship. That action allowed Kargan to save face and regain honor in the eyes of his officers, and likely averted an assassination attempt by Lieutenant Klag.

In 1930, during the first part of Earth's 20th Century, Keeler was a social worker who died in a street accident. Centuries later, during a survey of the Guardian of Forever by the USS Enterprise, the ship's Chief Medical Officer, Dr. Leonard McCoy, during a temporary bout of mental illness brought on by an accidental injection of cordrazine, escaped into Earth's past. While there, he saved Keeler from dying, which sparked a chain of events throughout the timeline, essentially changing history. In the altered timeline, Keeler, a passionate believer in peace, spearheaded a movement which delayed the entry of the United States into World War II, thus paving the way for an Axis victory. Ultimately, Starfleet, the Federation and the USS Enterprise were no longer in existence, but the proximity to the Guardian of Forever by the landing party allowed Captain James T. Kirk and First Officer Spock to follow McCoy into the past. Kirk and Spock were able to prevent McCoy from saving Keeler's life, thus restoring the timeline. These events were particularly stressful for Kirk, as he had fallen in love with Keeler.
KeevanChristopher SheaRocks and Shoals (DS9),

The Romulans had "conditioned" Geordi La Forge to receive E-band transmissions through his VISOR. Kell carried the transmitter that instructed La Forge to kill Governor Vagh, but the attempt failed.

KlaaTodd BryantTFF
Young Klingon captain of a Bird-of-Prey. He is also the gunner, as the tactical scope is mounted above his command chair and lowers like a periscope when he wants to fire the ship's disruptors. He is bored with shooting space garbage, such as Earth's Pioneer 10 probe, and longs for a bigger challenge to make a name for himself. When he learns that the Enterprise-A and Captain James T. Kirk are headed to Nimbus III, he arranges to intercept them. Klaa shoots at but misses the Enterprise, which suddenly engages warp speed. He follows her to Sha Ka Ree and this time scores a hit. He orders the Enterprise to surrender, but General Koord calls him off and forces him to rescue Kirk from the surface of Sha Ka Ree. At a "cocktail party" aboard the Enterprise, he salutes Kirk as a fellow warrior. One of Klaa's more memorable features, besides his muscles, is his wild "shock rock" hair.[original research?] Noncanon: In the movie novelization, Klaa's Bird-of-Prey is called Okrona.
KlagBrian ThompsonA Matter of Honor (TNG)
Klingon lieutenant and second officer of the IKS Pagh in 2365. He challenged Commander William Riker's authority over him as first officer of the Pagh during an officer-exchange program. After Riker beat him up, Klag agreed to take his orders and even respected the commander for his strength. Klag's father had once been captured in battle by Romulans, but not allowed to die. He eventually escaped, and now lives on Qo'noS, honorless, waiting for death by natural causes. For that reason, Klag won't see him. When Captain Kargan suspected that Riker was complicit in the Enterprise-D's "attack" on the Pagh, Klag disagreed and defended the commander.[3]

K'neraDavid FromanHeart of Glory (TNG)

When he learned that the criminals Korris, Konmel and Kunivas had been rescued by the Enterprise-D, he plotted an intercept course and demanded that Captain Jean-Luc Picard turn them over when he arrived. By that time, however, all three Klingons had died from injuries or during escape attempts. (Script Note: Picard mistakenly called K'near "captain" in one instance.)[4]
KodosArnold MossThe Conscience of the King (TOS)

In 2364, the trio stole the Talarian freighter Batris and subsequently destroyed the IKS T'Acog, which had been sent to retrieve them. After being rescued by the Enterprise-D, Korris and Konmel lied to Captain Jean-Luc Picard about the battle, but later revealed their true intentions to Lieutenant (j.g.) Worf. By then, Klingon commander K'near had apprised Picard of the Klingons' criminal status, so Picard detained them in the brig. They escaped, but Konmel was killed in a firefight with Enterprise-D security. To his credit, though, it took three phaser shots to bring him down.
KonsabNoneFace of the Enemy (TNG)
Romulan commander and former instructor of military history at the Romulan Intelligence Academy. His main theme consisted of theories on the differences between the military and the Tal Shiar. He believed that military officers must trust one another to function. (The dialogue was unclear, but Konsab may have been Commander Toreth's father. She described him as an "idealistic old man" and a "devoted citizen who only tried to speak his mind". The Tal Shiar dragged him from his home in the middle of the night, and Toreth never saw him again.)
KoordCharles CooperTFF
A fat Klingon general who fell out of favor with the High Command and ended up serving in the dishonorable role of Klingon consul to the "Planet of Galactic Peace," Nimbus III. In his younger, leaner days, Koord was such a notable soldier that his military strategies were required reading at Starfleet Academy. On Nimbus III, he and his Federation and Romulan counterparts, St. John Talbot and Caithlin Dar, were taken hostage by Sybok's "Galactic Army of Light." Later, Spock convinced Koord to use his authority and order Captain Klaa to destroy the alien creature on Sha Ka Ree and transport Captain Kirk to safety.

John Colicos reprised the role in three Deep Space Nine episodes, as an ally and friend of Jadzia and Ezri Dax.

However, when he says that the Enterprise should be hauled away as garbage, Scotty throws the first punch.
KorrisVaughn ArmstrongHeart of Glory (TNG)
Klingon captain who, with Konmel and Kunivas, left the Klingon Defense Force to pursue a life in which he could live like a "true Klingon." In 2364, the trio stole the Talarian freighter Batris and subsequently destroyed the IKS T'Acog, which had been sent to retrieve them. After being rescued by the Enterprise-D, Korris and Konmel lied to Captain Jean-Luc Picard about the battle, but later revealed their true intentions to Lieutenant (j.g.) Worf. By then, Klingon commander K'near had apprised Picard of the Klingons' criminal status, so Picard detained them in the brig. They escaped, but Konmel was killed in the process. Korris fled to Main Engineering and held a makeshift phaser to the warp core, demanding to speak to Worf. His attempt to sway Worf to his cause failed, however, and Worf shot him dead.[5]

KovalJohn FleckInter Arma Enim Silent Leges (DS9)
Romulan chairman of the Tal Shiar in 2375. He had not been elevated to the Continuing Committee of the Romulan People, which is normally accorded to a person in his position, because of his opposition to the Romulan alliance with the Federation, which was supported by a majority on the committee. He was rumored to be ill with Tuvan Syndrome, which may have been another reason why he had not been elevated to the Continuing Committee. Secretly, Koval had been providing critical military intelligence to the Federation for more than a year. He was Vice Admiral William J. Ross' guarantee that the Romulans would not make a deal with the Dominion.

After following Maab's war party into the mountains in pursuit of Kirk, Spock, McCoy and Eleen, the widow of Akaar, Kras captured Eleen with a Starfleet hand phaser to force her to prove that she'd killed the Enterprise landing party. Maab drew out Kras by making himself a target. When Kras vaporized Maab, another Capellan warrior, Keel, killed Kras with a kligat.[6]

KrellNed RomeroA Private Little War (TOS)

He did this by supplying the Villagers with flintlocks, and every so often, he'd return to provide "improvements" to Apella, leader of the Villagers. Krell also dispensed advice to Apella on how to deal with special situations, such as which Villager should be given a captured woman of the Hill People. With such teachings, Krell promised Apella a governorship in the Klingon Empire. When Kirk and McCoy discovered the flintlock "factory", Krell got himself punched out by the Enterprise captain and was heard from no more.
KrugeChristopher LloydSFS
Klingon commander of a Bird-of-Prey. His crew address him as "my lord", as do his ill-fated lover, Valkris, and Lt. Saavik. He receives a stolen summary of Project Genesis from Valkris and decides to act for the preservation of his race. He goes to the Genesis planet to learn the secret of the Genesis torpedo and secure for himself the "ultimate power". His gunner accidentally destroys the Federation science Starship Grissom, but Torg finds survivors on the surface. When the Enterprise arrives and scores a successful hit on Kruge's ship, he accepts Admiral Kirk's hail and threatens to execute one of the "hostages" on Genesis. That hostage ends up being Kirk's son, David Marcus, and in retribution, Kirk destroys the Enterprise while the bulk of Kruge's crew is aboard, intending to commandeer the starship. Later, Kirk and Kruge fight to the death on Genesis while the planet burns around them. Kruge is the loser.
K'TemocLance LeGaultThe Emissary (TNG)
Klingon captain of the IKS T'Ong, a K't'inga-class battle cruiser that was dispatched before 2290, when the Federation and the Klingon Empire were still exchanging hostilities. K'Temoc's mission was so crucial to the Klingon High Command that he and his crew were placed in cryogenic sleep for more than 75 years. In 2365, the Klingon High Command received an automated message from the T'Ong stating that it was returning home and was about to reach its "awakening point". K'Temoc had been given standing orders to fire on all Federation ships, which he carried out on encountering the Enterprise-D. However, he was tricked into lowering his shields and yielding command of the T'Ong to "Captain" Worf and "Commander" K'Ehleyr, who convinced K'Temoc that the "war" was over.

Years later, as a member of the Klingon Defense Force, Commander Kurn participated in an officer-exchange program with Starfleet that landed him aboard the USS Enterprise-D and reunited him with Worf ("Sins of the Father"). More than a year later, Captain Kurn commands his own K'Vort-class bird-of-prey and sides with Gowron during the Klingon Civil War ("Redemption II"). More than four years later, a ruined Kurn appears on Starbase Deep Space 9 ("The Sons of Mogh") and asks Worf to kill him to restore his honor, which, along with his seat on the Klingon High Council and the House of Mogh's most valuable possessions, were stripped from him because Worf fought against Gowron during the chancellor's takeover of Cardassia Prime ("The Way of the Warrior").
KunivasRobert BauerHeart of Glory (TNG)
Klingon officer who, with Korris and Konmel, left the Klingon Defense Force to pursue a life in which he could live like a "true Klingon." In 2364, the trio stole the Talarian freighter Batris and subsequently destroyed the IKS T'Acog, which had been sent to retrieve them. Kunivas was critically injured in the battle and later died in the Enterprise-D sickbay.

Her assignment was as xenopsychologist to nonhuman species in Starfleet Command, and she also served as Nogura's personal representative to the "new human" groups on Earth. She was a last-minute addition to the Enterprise crew, which needed an officer trained in her xenopsychiatric specialty. Her death was a terrific blow to James T. Kirk, with whom she had lived for one year after the Enterprise's five-year mission.

Kirk enters the Bridge and takes Maltz prisoner at phaser-point, promising to "kill" him later for not piloting the Bird-of-Prey away from Genesis. Maltz may have been Kruge's tactical officer, as he counted down the kellicams before the Bird-of-Prey came within firing range of the Enterprise.
MaraSusan HowardDay of the Dove (TOS)
Klingon science officer and wife of Kang. She is evacuated from his wrecked ship to the Enterprise and fears for how all Klingon survivors will be treated at Federation hands. Her concerns seem to be well-founded when Ensign Chekov takes out her bodyguard and then begins assaulting her. Kirk and Spock rescue her, and then show her firsthand evidence of the alien "entity" that has invaded the Enterprise and pitted Starfleet officers and Klingons against each other. She explains to Kirk that her people are hunters because there are poor planets in the Klingon system, and they must push outward to survive. She brokers a meeting between Kang and Kirk, which eventually leads to a truce. With "good spirits" from both parties, the alien entity flees the Enterprise.

When Spock steals the Enterprise and heads for the Talos Star Group, Kirk and Mendez pursue in the Shuttlecraft Picasso … except that Mendez really isn't there at all, or later aboard the Enterprise during the court-martial of Spock.

Mitchell also "aimed a little blonde lab technician" at Kirk, who almost married her. Later, on the planet Dimorus, Mitchell almost died from a poisoned dart thrown by "rodent things" who were aiming for Kirk. In 2265 aboard the Enterprise, Mitchell is "zapped" by the Galactic Barrier, which turns his eyes glowing silver and grants him enhanced ESP powers.

He also promoted Scotty to "captain of engineering" and reassigned him to the USS Excelsior NX-2000. In addition, he announced that the Enterprise would be decommissioned, thereby denying Kirk the opportunity to take her back to the Genesis planet. Later, when Kirk pressed the issue and explained that Spock's katra must be reunited with his body, Morrow cautioned him against "intellectual chaos" and implored him to remain rational, lest he lose everything and destroy himself. (Noncanon: In the movie novelization, Morrow's first name is "Harry".)

  3. ^ Script Note: Klag said, "A Klingon is his work, not his family. That is the way of things." This is untrue; in fact, it's rather the reverse, as the third-season episode "Sins of the Father" will begin to illustrate. A Klingon's house/family is basic to his or her very existence. Without one, he or she is nothing.

This one-time-only display implied that the Federation/Klingon alliance was much more than a simple "mutual defense" pact or the like. It also explained why Klingons like Korris, Konmel and Kunivas felt that their birthright had been traded away for peace, and also spoke to Q's offhand comment in "Hide and Q" that the Federation had "defeated" the Klingons.
  5. ^ Script Note: Picard mistakenly called Korris "commander" in one instance.
