Kor " Dahar " Master Kor , son of Rynar was a male Klingon military officer and ambassador in the 23rd and 24th centuries . He was among the most influential warrior s and respected military leaders of the Klingon Empire . Kor was the last son of the House of Kor and descendant of the Klingon Imperial Family . He also had a son . He was descended from Klingons affected with the augment virus created in 2154 , a product of 22nd century Klingon genetic engineering . By the 24th century , he was cosmetically indistinguishable from an average Klingon . ( ; ; ) Throughout his illustrious career , Kor played key roles in many legend ary battles against the Federation and Romulan Empire . Kor ' s influence in the Empire eventually elevated him to the status of Klingon " Dahar " Master . ( ) During his life , he saw the Klingon military changing its name from Klingon Imperial Fleet to Klingon Defense Force . Military career . By the 2260s , Kor had achieved the rank of commander and was assigned to a Klingon warship . ( ) Conflicts with the Federation . In 2267 , following the breakdown of peace talks between the Federation and the Klingon Empire , a broke out . The neutral planet of Organia , a strategic position between the two powers , became a political hotspot between the Empire and the Federation . On stardate 3102 . 7 , Commander Kor led a battalion of five hundred Klingon soldier s in an invasion and occupation of Organia , where he briefly became their military governor . As governor , Kor ruthlessly maintained order on the planet , ruling with an iron fist by maintaining a stringent list of rules , any violation of which was punishable by death . Unknown to Kor at the time , Captain Kirk , posing as an Organian , and Lieutenant Commander Spock , posing as a dealer in keva s and trillium , were among the subjugated . The two Starfleet officers mounted vain guerrilla attacks against Kor and his army . Meanwhile , in orbit around Organia , the Klingon and Federation fleet s faced each other in battle . Once the hostilities between the two began to reach its climax , all ships suddenly and mysteriously became paralyzed and all weapons became superheated and temporarily rendered useless . Unknown to both sides at the time , the Organians were , in fact , an advanced non - corporeal species , despite their primitive way of life . As quickly as it started , the Organians effectively ended the occupation , the war , and Kor ' s governorship . ( ) The Organians continued to promote peace between the two powers by imposing the Organian Peace Treaty . ( ) Within two years , Kor became the commanding officer of the . In 2269 , Kor again faced his enemy , Captain Kirk , in battle , when the " Klothos " engaged the in the Delta Triangle region . During the battle , the two starship s became entangled in a " time trap , " a phenomenon unique to that region , pulling the ships into an alternate universe known as Elysia . Kor attempted to escape but the " Klothos " was unable to break free from the region , partly due to its unusual properties , including draining dilithium crystal s of their energy . Through cooperation , the crew s of the " Enterprise " and " Klothos " were able to formulate a strategy by combining their warp power in an effort to overcome both ships ' individual power deficiencies . Prior to their attempt , however , Kor had one of his officers , Kali , plant a bomb - like device in the computer room of the " Enterprise " , set to explode once the starship cleared the phenomenon and reached warp eight . Both ships were able to escape the region , and the destruction of the " Enterprise " was averted , moments before the ship reached warp eight . Nevertheless , Kor claimed responsibility for formulating their combined escape and returned to Klingon space , no worse for the wear . ( ) Kor ' s ship , the " Klothos " , was one of the first Klingon vessels equipped with a cloaking device . Kor was said to have spent three days in the engine room taking it apart and studying it before their first mission . This proved critical when he later commanded one of the two Klingon divisions aboard the " Klothos " , along with Kang , in an attack against the Federation outpost at Caleb IV . During the attack , Kor successfully tricked his opponent by launching first a small initial attack , and then striking with the bulk of his forces when the Federation began repair efforts . ( ) Conflicts with Romulans . Kor was involved in several combative entanglements with the Romulan Star Empire . In 2271 , Kor led the Klingon Empire to a glorious victory over the Romulan s , at the legendary Battle of Klach D ' kel Brakt . Kor liked recreating the battle so much that he called it up each time he went to the holodeck . On one occasion before he went on his quest to kill The Albino , he was playing this battle in the holosuite and he got so drunk with Breshtanti ale that Odo had to put him in a holding cell to sleep it off . ( ) Worf once recalled a story he had heard about Kor during his own childhood , which described Kor ' s " attack on Romulus . " ( ) Later career . Kor , with fellow warriors Koloth and Kang , held the Korma Pass against T ' nag ' s army in a glorious battle in a trinary star system , where they forced the enemy to fight with the blinding light of three sun s in their eyes . The battle ended with the mountain side covered with so many dead that there was not a square meter of ground to be seen . They together feasted on T ' nag ' s heart , in celebration of their victory . ( ) Kor became a close friend to Curzon Dax , the Federation ambassador to Qo ' noS , in 2289 . In one of their escapades , Kor and Dax broke into the duke ' s harem on Renavi . In 2370 , when Kor and Jadzia Dax , Curzon ' s successor , were reunited , Dax knew Kor well enough to recall that he had a scorcher burn on his fourteenth rib , and that his left QiVon ached every time his ship hit warp eight . ( ) During the late 2280s , a band of depredators , led by the Albino , began raiding Klingon colonies . Three Klingon warships , led by Kor , Koloth , and Kang , were sent out to stop him . Their mission was successful , as they captured most of the depredators . However , the Albino was able to escape . In the Albino ' s last message to the Klingons , he promised to take his revenge on the firstborn of each of the three captains . Within the space of a few years , he kept his word and managed to infect the warriors ' three innocent children with a genetic virus that eventually killed them all . ( ) The Reckoning . In 2290 , Kor , Kang , Koloth , and Curzon Dax pledged a blood oath to avenge the deaths of the Klingons ' sons , the offense committed by the Albino . They nearly caught him at Galdonterre , but one of their subspace messages was intercepted and he , once again , was able to escape . After decades of searching , Kang learned of the whereabouts of the Albino , in 2370 , on the planet Secarus IV . Kang traveled to Secarus IV and discovered his compound . The Albino knew immediately of his arrival and invited the trio to a " fair fight " and one last , glorious battle . Kang contacted both Kor and Koloth for a rendezvous on Deep Space 9 , in preparation of their final attempt to complete their lifelong quest . Three months later , Kor , Koloth , and Kang , with the aid of Jadzia Dax , prepared their attack on the Albino ' s compound , only to discover that it was a trap . Using the element of surprise , they bombarded the compound with tetryon particles , forcing the Albino and his sentries into face - to - face , hand - to - hand combat . Koloth was fatally wounded fighting the Albino ' s personal guard . Following a fierce duel , Kang was able to slay the Albino ( held at bay by Dax ) before he died as well . Having fulfilled their blood oath , both Kang and Koloth died glorious and honor able deaths . ( ) Political career . Kor was a member of the Oversight Council for the Klingon Defense Force s when ( future General ) Martok attempted to join in 2345 . Kor was responsible for striking Martok ' s name from the officers ' list because his family was from the lowlands of Ketha Province , and due to his influence , Martok was barred from even enlisting as a common soldier . Martok remained bitter about this incident for nearly thirty years . ( ) In the early 2370s , Kor was serving as the Klingon ambassador to . In 2371 , a Vulcan expedition found the Shroud of the Sword ( of Kahless ) among the remains of a Hur ' q outpost in the Gamma Quadrant . Using his influence as ambassador , Kor was able to acquire the Shroud from the Vulcans . Kor , however , had a penchant for drinking and for telling stories . On one drunken occasion in a tavern on Torna IV , Kor held a group spellbound with the story of the ancient cloth and how it was going to lead him to the Sword of Kahless . One member of his audience , Toral , son of Duras , was so intrigued he sent a Lethean named Soto after Kor , aboard Deep Space 9 , to steal his memories of the discovery . In early 2372 , Kor , with the assistance of Starfleet officers Lieutenant Commander Jadzia Dax and Lieutenant Commander Worf , launched a quest to find the legendary Sword of Kahless in the Gamma Quadrant , using the data collected by the Vulcans . While unknown to them at the time , they were being trailed by Toral , who intended to steal the Sword and use it to lead the Empire . Following the successful discovery of the Sword , the enormous symbolism of it became a matter of contention between Worf and Kor . After realizing that the Sword would only serve to further divide the Klingon Empire , rather than reunite it ( as the legends foretold ) , they set the Sword adrift in interstellar space . ( ) Lost influence . In 2375 , Kor , having long been out of favor with Chancellor Gowron and the High Council , and unable to secure his own command , used his remaining influence to persuade Worf to recommission him into the Klingon Defense Forces . With Worf ' s assistance , Kor was commissioned to serve as the third officer aboard the , while they made a daring cavalry raid into Dominion - held space . Unfortunately , during this time , Kor was suffering from frequent lapses in memory and concentration , often losing track of where and when he was . At a critical moment , when both Worf and Martok were incapacitated on the bridge while engaging the Cardassian base on Trelka V , Kor suffered such a lapse . Kor believed himself to be once again engaging the Federation outpost at Caleb IV , at the side of his long dead friend , Kang . As a result of his lapse , the " Ch ' Tang " was nearly destroyed , and the captain and first officer of their sister ship , the , were killed . They were able to escape the system only to discover that a fleet of Jem ' Hadar fighters was pursuing them . Kor was subsequently relieved of duty . His standing aboard ship changed from an honored hero of legend to a pitiful disgrace . As it turned out , Martok took no joy in Kor ' s humiliation . Martok mentioned this to Worf when discussing the duty roster . Both officers then agreed that they would both be speaking to Gowron to find an assignment for Kor . It was through the experience and bravery of Kor , and six volunteers , that the was able to successfully engage the Jem ' Hadar fleet . Realizing that the Jem ' Hadar would soon overtake them , Worf had suggested using the " Ning ' tao " to force the enemy out of warp and engage the fleet , intending to lead the attack himself . Before Worf could beam to the doomed ship , however , Kor – secretly informed by Martok ' s assistant , Darok – stunned him with a hypospray and took command himself . Before leaving , he promised Worf that , when he passed into the halls of the honored dead , he would find Worf ' s beloved wife , Jadzia Dax , and tell her of Worf ' s love for her and how he had brought her honor . Kor died pulling off an amazing feat of tactical brilliance . While on his last mission , he was able to take charge of a Klingon Bird - of - Prey and stall ten Jem ' Hadar ships long enough for the remaining Klingon ships to reach the Starfleet reinforcements located in the Kalandra sector . Even General Martok , putting aside the past , toast ed the " Dahar " Master ' s bravery , noting that Kor had been " " a noble warrior to the end . " " ( ) Personal views . Kor was from a generation of Klingons not known for standing on ceremony , eating when hungry , and fighting when angry . Kor had a somewhat more progressive view when it came to interactions with other species and gender s . Having seen the Trill ambassador Curzon Dax as a brother , he saw no difference calling Jadzia Dax a sister , when it was time to fulfill their blood oath . ( ) Kor displayed a calm demeanor when interviewing James T . Kirk on Organia , admitting he held a great admiration for the captain and for Starfleet of the 23rd century ; Kor recognized many similarities between Humans and Klingons , seeing the killer instinct within Humanity , and likening he and the captain to tiger s . ( ) Kor , however , felt that the Klingon social order was important , that nobility was something that Klingons in the early 24th century still held with esteem , and would enforce the status quo of Klingon society by striking the name of common applicants from officer candidate lists . ( ) Appendices . Background information . Kor was played by actor John Colicos in all of the character ' s live - action appearances and was voiced by James Doohan in . Name . There was originally some question as to the pronunciation of Kor ' s name , as Kirk actor William Shatner decided the way the moniker was said should be altered . " " Bill had some idea that it sounded like ' canine corps ' or something like that , so he decided to change it , " " explained John Colicos . " " I said , ' But if it ' s going to be pronounced " Koor , " then I ' m going to be selling Coors beer . ' So , there was a bit of palaver about that , but we wound up doing what we did because it was Bill ' s suggestion . " " ( " " # 138 , pp . 17 - 18 ) This pronunciation for Kor ' s name was listed in the pronunciation guide for " Blood Oath " . In Marc Okrand ' s " tlhIngan Hol " language , Kor ' s name was qor . ( " The Klingon Dictionary " 2nd ed . , p . 58 ) Introduction . The script for detailed that , upon being introduced in that episode , Kor was " holding himself proud and erect and firm . . . obviously a man accustomed to command . . . a warrior . " Having worked with John Colicos before , " Errand of Mercy " Director John Newland selected him to play Kor . ( ' # 130 , p . 77 ) Newland suggested Colicos for the part , immediately after being assigned to direct the installment . Colicos was living in either Toronto or New York at the time . ( ' # 138 , p . 17 ; ) He later recalled , " " I got a phone call , ' Would you come out to California to do an episode of " Star Trek " ? ' I said , ' Yes , of course . ' The script was sent . It arrived about two hours before I went to the airport , so I learned the lines on the plane between chicken sandwiches . " " ( ' # 138 , p . 17 ) Never having heard the species name " Klingon " , Colicos was extremely unsure how to portray the role . ( ) After arriving at the " Star Trek " studios , he immediately went to have Kor ' s Klingon makeup applied for the first time . The fact that the character was meant to be an ambitious military commander led Colicos – who was given the opportunity to influence his makeup , due to it being such a last - minute job – to suggest drawing influence from Genghis Khan for Kor ' s appearance . ( ' # 138 , p . 17 ) Kor was initially to have appeared in ; the writer of that episode , Jerome Bixby , very much wanted to cast John Colicos as the installment ' s main Klingon character . ( ' # 164 ) Kor was included by Bixby in the third revised story outline for " Day of the Dove " , which he submitted on . The Klingon character was also the subject of a note Bixby sent to " Star Trek " Producer Gene Roddenberry , along with the newly revised outline . The note read , " " Have used the Klingon KOR from ' Errand of Mercy ' . The character was strong , the actor wonderful . " " ( " " ) Colicos was again offered the role and could hardly have been more excited by the prospect of appearing in " Day of the Dove " . However , he was unavailable , meanwhile involved in a film being produced in Italy . ( ' # 164 ) According to Bixby recollecting what Colicos had said , the actor was so frustrated that he couldn ' t portray Kor in " Day of the Dove " ( due to his film commitment ) that , when he first read the episode ' s script , he wept , threw himself at walls , banging his head on a wall , and almost jumped off a balcony , resisting the urge to do so . ( " " , p . 71 ; " " # 164 ) Ultimately , Kor was written out of the episode ' s script by Fred Freiberger , with a revised final draft script submitted by him on . The elimination of Kor definitely had some aftereffects . For example , it was implied in the episode that there was already some pre - existing familiarity between Kang , who was created to replace Kor ' s role in the story , and Captain Kirk . Also , a line of dialogue which needed to be cut was one of the first the Klingon spoke in the script , when he exclaimed , " " Kirk ! The last time we met – an incident ! This time , you will be cut up in your own stew ! " " ( " " ) In fact , John Colicos was twice asked to reprise the role of Kor , during the original broadcast run of ; Gene Roddenberry wanted to make the character a recurring one . ( " " # 138 , p . 18 ) In a interview , Colicos admitted , " " I always wonder how it all would have materialised had I been more available during the original series . " " ( ) Reappearances . During the writing of the episode , the writing staffers who worked on struggled with deciding what direction to take the character of Kor in , more than they did with Kang and Koloth . " " We weren ' t sure about him , " " conceded Ira Steven Behr . " " His character was a tougher nut to crack . " " Peter Allan Fields , who was credited with writing the episode ' s story and teleplay , based Kor ' s persona on the Shakespeare character . ( " " , p . 132 ) When John Colicos was needed to play Kor in " Blood Oath " , DS9 ' s casting personnel managed to quickly find the actor . ( " " , p . 131 ) Being invited to return as Kor surprised Colicos , though . " " When I first read parts of the script I said , ' No , no , no , you ' re making a travesty of what has become a cult figure , this super marshal warrior . ' I had a long talk with Michael Piller and he said I only had the first part of the script and that they were going to do this and that . He said that I was going to become a heroic figure in the end . " " ( ) One issue that John Colicos had with the script for " Blood Oath " , while the DS9 producers were uncertain whether to kill off the entire trio of returning Klingons or allow one to survive , was that he wanted Kor to be kept alive . " " I said , ' If one of us is left alive , then I , like Ishmael , have to be left to tell the story . ' I said I didn ' t want to be killed off , otherwise I ' d have preferred just to be remembered as the initial Commander Kor that people saw in the original series [ . . . ] I really would not have done it . The way the character evolved , I thought that unless I got some opportunity to leave in the public ' s mind the idea that Kor didn ' t just turn into a fat , old Falstaffian drunk , but that he had some heroic , redemptive qualities left in him , there was no point in my doing the show . I didn ' t want to destroy a whole image just for the sake of one appearance . " " Following much consideration and writing , the DS9 producers decided that Kor was the one who would live . " " I don ' t know whether or not my being the first Klingon on " Star Trek " , " " Colicos mused , " " influenced them in any way . " " ( ) Once the " Blood Oath " script had been heavily rewritten , John Colicos was very pleased with the way it wound up depicting Kor . ( ) He remarked , " " It was fascinating , all of these years later , to come back to " Star Trek " , and to come back as an almost entirely different character . He ' d grown into this almost Falstaffian blimp of a character . " " ( ) Colicos was curious how even his look had changed so drastically in the intervening years . The revised makeup involved in playing the part in " Blood Oath " regularly required Colicos to get up at 4 a . m . ( ) Reception . The way in which John Colicos established Kor in " Errand of Mercy " pleased several production staffers . Fellow Klingon - playing actor Mark Lenard , who appeared as a Klingon captain in , described Colicos as " a very good Klingon . " ( ' # 138 , p . 35 ) At one point , Spock actor Leonard Nimoy commented that Colicos ' initial portrayal as Kor was " " Wonderful . He had that authority . " " ( ) John Newland was likewise impressed with the same performance , saying of Colicos , " " [ He ] gave me everything I wanted . " " ( ' # 130 , p . 77 ) Writer and editor Robert Greenberger once cited Kor as his favorite Klingon . ( " " # 138 , p . 71 ) The official promotional material featuring Kor in his introductory appearance was restricted . " " There is only " one " photograph , a head shot of me as Kor that was taken as a publicity still , so there must be many pirated pictures around , " " Colicos once predicted , in the late 1980s . " " I keep getting color photos sent from all different parts of the world , with Bill [ Shatner ] and myself in a scene . People keep sending them for autographs , so it has become a very identifiable face . " " ( ' # 138 , p . 18 ) In a poll to determine favorite Klingons voted by readers of ' ( a poll which ran between issues 143 and 149 of the magazine , from June 1989 to December of that year ) , Kor came second to Worf . ( " Starlog " # 149 ) Indeed , many " Star Trek " fans came to regard John Colicos as the " King of Klingons , " with the actor himself noting , " " There seems to be a cult following on Commander Kor . " " Colicos also remembered that , at a 25th Anniversary " Star Trek " convention at Mason Phillips Square in , he was given a warm welcome by the attendees , of whom there were 14 , 000 . " " I was the mystery guest . When they announced my name and I came out I thought I was the President of the United States , " " Colicos reminisced . " " It was unbelievable . " " ( ) Apocrypha . Kor is mentioned in the novel " Dwellers in the Crucible " , where his full name is given as " Kor " epetai " Zareht " . In the short story " " , Kor attacks the USS " Enterprise " commanded by Robert April . This delayed the " Enterprise " in getting supplies to Tarsus IV , resulting in the deaths of 4 , 000 colonists . In the 1992 comic book " Debt of Honor " , Kor works together with Captain Kirk and Romulan Commander T ' Cel to fight a species of hostile insectoid creature s . Kor is the main antagonist in the " " crossover series , where he supplies advanced rifle s to Gorilla general Marius . Kor appears in the short story " The Leader " , where his son D ' kar tries to kill Kirk in revenge for his father ' s loss of honor at Organia . In another short story , " The Unhappy Ones " , Kor , Koloth , and Kang were sent to Beta Thoridar to settle a dispute between the smooth - headed " QuchHa " ' Klingons and the ridged " HemQuch " Klingons . In the novel " Treaty ' s Law " , Kirk and Kor work together to defend a Klingon colony from an alien race called the Narr . Kirk and Kor again worked together in the novel " The Tears of the Singers " , to investigate a mysterious phenomenon near Taygeta V , which threatened to destroy the planet . The novel " Forged in Fire " detailed the friendship of Kor , Koloth , Kang , and Curzon Dax , and the start of their blood feud with the Albino . In the comic books " Errand of War ! " and " Deadly Allies ! " Kor and Kirk work together to thwart the Excalbian s , who had started a war between the Federation and Klingon Empire as part of their continuing experiment s on the nature of good and evil . In " " miniseries , Kor attacked a mining outpost on Loren 5 and destroyed Deep Space Station K - 22 as part of a plot to take control of Preserver artifacts on Loren 5 . The alternate reality version of Kor appears , captaining the , in " " . Therein , he leads the capture of Nero and the " Narada " , following the ship ' s collision with the in 2233 . In this of Kor in the alternate reality , he has not been affected by the augment virus and appears as a normal Klingon . He also appears in Issue 4 of the IDW comic series " " . The mirror universe counterpart of Kor featured into the novel " The Sorrows of Empire " . Kor appears in the " Star Trek Online " expansion " Agents of Yesterday " . In the mission " Battle of Caleb IV " , Kor allies himself with the Na ' kuhl and sets a trap for a group of Federation starships , including the player character . The player is able to defeat Kor ; however , he gets revenge by destroying his ship .
