Na ' kuhl The Na ' kuhl were a species that evolved to gain a certain degree of control over time . During the 29th century , they were a faction in the Temporal Cold War – vehemently opposed to the Temporal Accord – and were led by Vosk , a dangerous fanatic who viewed time travel as his innate right despite the damage that consequently might be done to the timeline . Physiology . The Na ' kuhl had pale complexions , bony - looking faces with bat - like features as well as bright red eye s , and many veins visible on their bald heads . ( ) They also had yellowish - brown blood . ( ) Weapons and other technology . The Na ' kuhl were equipped with extremely powerful plasma rifle s . Although these weapons required much power for portable usage , the attainment of such power was apparently very easy for the Na ' kuhl in their native time period , where there were – according to an account of uncertain credibility that Vosk once made – energy cells as small as a coin . According to the same account , the Na ' kuhl were additionally capable of unleashing a plague that targeted victims based on their genetic profile and could be dispersed throughout an entire country by introducing a few grams of a pathogen into that country ' s water supply . The Na ' kuhl also used a style of hand - held communicator , in addition to the time - traveling technologies they developed at different points of their development . ( ) Subjective history . Origins . The ancestors of the Na ' kuhl under Vosk ' s leadership worshiped god s , and Vosk once referred to them as having been considerably imaginative but substantially less technologically developed . At another time , a Na ' kuhl who Vosk later respectfully described as " our greatest scientist " stated , " " Every moment we live , we are moving through time . We ' ve earned the right to choose which direction . " " At one point in their history under Vosk ' s leadership , the Na ' kuhl attempted to eradicate the Suliban . They traveled into the past to prevent the Suliban from becoming sentient . However , an opposing faction of temporal agent s stopped the Na ' kuhl and ensured that the Suliban attained sentience , despite the ongoing enmity between the Temporal Agents and the Suliban . ( ) Seeking refuge . The Na ' kuhl were very nearly defeated and captured by ' faction , but managed to develop a type of stealth time travel before they could be vanquished . This innovative device had the drawback of allowing only one - way travel . Using the device , the Na ' kuhl escaped to Earth in 1944 of an alternate timeline created by multiple temporal incursion s from the different factions . , with the assassination of Vladimir Lenin by an unknown faction , Nazi Germany had been able to concentrate solely on the Western Front during World War II , allowing Adolf Hitler to quickly take over England and then much of the eastern coast of the United States , including New York City and Washington , DC . The Na ' kuhl were allies to the Nazis and were granted ranks in the SS , complete with the " privilege " to wear SS uniforms as well as several Nazi medals . The Na ' kuhl further offered to provide advanced technological weaponry to the Nazis , but held back from doing so , not trusting the Human forces and being less interested in their war than they were . In exchange , the Nazis provided the Na ' kuhl with materials to build a temporal conduit with which to return to the future , so that they would no longer be trapped in the past . In fact , the Na ' kuhl were forced to create the conduit exclusively from materials acquired from that time period . The group was eventually successful and , just after Vosk was finally located by the Temporal Agents , the Na ' kuhl used the conduit to journey to the 29th century , where they ignited the war they were nearly defeated in . This offensive not only enabled the Na ' kuhl to defeat the opposing faction but also ignited the Temporal Cold War into an all - out conflict , resulting in the very same alternate timeline to which the Na ' kuhl had escaped in the first place . ( ) In a last - ditch effort to restore the timeline and stop the Na ' kuhl , Daniels transported Captain Jonathan Archer and from 2154 to 1944 . ( ) Shortly after a wounded Archer was captured and hospitalized by the Nazis , the Na ' kuhl had some involvement in overseeing his recovery . ( ) However , this degree of supervision was found , by Vosk , to be insufficient ; after Archer escaped during an unsuccessful Nazi attempt to transfer him , another Na ' kuhl named Ghrath was blamed by Vosk for neglecting to personally supervise Archer ' s transfer . Having discovered that Archer was from the future , the Na ' kuhl time travelers at first came to the incorrect conclusion that he and the crew of " Enterprise " were Temporal Agents themselves . ( ) The physical appearance of the Na ' kuhl was generally met with shocked responses from citizens of the era and the unexpected presence of the aliens generated some stories about their existence , rumors that gangster and resistance fighter Sal learned of . The extravagance of these tales caused an associate of his , Alicia Travers , to initially disbelieve the reports . When Archer and the resistance cell traced the tales back to their source , an informant for Ghrath named Joe Prazki claimed that – even though he had only ever glimpsed Ghrath on one occasion – Ghrath ' s red eyes had been enough to leave Prazki with an unforgettable impression . For one resistance fighter called Carmine , the act of seeing Ghrath ' s Na ' kuhl features caused him to almost utter an expletive in alarm and speculate that they might be simply those of a mask , a theory that was quickly denied by Sal . He referred to Ghrath as a " freak " and shot him to death . A later suggestion from Carmine was that the Na ' kuhl had looked like a demon . Somewhat simplifying the group ' s struggle to identify Ghrath ' s appearance , Archer revealed that he had been an extraterrestrial . Sal ' s first instinct was to question whether the alien had originated from Mars , though Archer admitted to being unsure about what planet Ghrath had come from . ( ) From that point onward , Carmine considered the Na ' kuhl to indeed be Martian s . ( ) A squadron of Stuka airplanes under Vosk ' s command were outfitted with hi - tech Na ' kuhl weaponry . The crew of " Enterprise " was ultimately successful in their mission , managing to destroy the conduit moments before Vosk could enter . This had the effect of eliminating the changes he had made , unraveling this timeline , and bringing the Temporal Cold War to an end . ( ) Appendices . Background information . The name " Na ' kuhl " comes from the , and was not used on screen or in the final drafts of the scripts . Although this species is first glimpsed at the end of , the final draft of the script for that third season finale does not include them . Nevertheless , the appearance of an alien in Nazi uniform at the episode ' s conclusion – looking decidedly out of place in the World War II setting of a Nazi medical tent – was thought up by Rick Berman and Brannon Braga , who wrote the episode ' s script . ( ) The idea originally started with the members of the series ' writing staff often joking amongst themselves that , following the end of the Xindi incident , the crew of " Enterprise " would finally return home to Earth only to find that the planet had been invaded by giant cockroach es . Certain only that they themselves were uninterested in such a twist ending being " a Xindi cliffhanger " ( in Braga ' s words ) , the writing team began to seriously consider the possibility of an unexpected conclusion to the year . " " We went through a lot of different scenarios about what they would find when they got back home , " " offered Braga . " " I can ' t remember who said ' Nazis , ' but we just somehow ended up with Nazis . Then that didn ' t even feel like enough , so we decided to make it alien Nazis . We decided to do something that would just be completely unexpected , yet give us something fun for [ the ] next year , to kick off the season with something really interesting . So we took a stab at it . " " ( ) Brannon Braga was aware that there had similarly been alien Nazis in both the ( Ekosian s in ) and ( Hirogen in the two - parter and ) , also having been personally involved in the latter instance . ( ) According to Rick Berman , however , no - one on s writing staff worried , upon introducing the Na ' kuhl , that they were too similar to " Star Trek " s previous Nazi aliens . ( ) Rick Berman was pleased with the audience reaction to the brief appearance of this species in " Zero Hour " . " " Well , I think we got a little bit of a shock and surprise , which is what we hoped for , " " he said . ( ) During the lead - up to the debut airing of the fourth season two - parter and , the alien Nazis were repeatedly rumored , on the Internet , to be Reman s – who had previously been seen in – though these incorrect reports were quickly refuted by Rick Berman . ( " Enterprise Supplement " ; ) At the time , he stated , " " I have read a lot of interpretations of what it might be but , in fact , we have not seen it before . I have seen people comment that it looked like a Reman , but this is a totally new alien . " " ( ) In a deleted scene from the episode " Storm Front " , Sal privately hypothesizes to Archer that the alien seen by him at the end of " Zero Hour " may have actually been the result of one of numerous experiments that the Nazis were reported to be conducting on Humans , a possibility that Archer says he hadn ' t considered . ( ENT Season 4 DVD ) Golden Brooks , the actress who played Alicia Travers and thereby appeared with the Na ' kuhl in the " Storm Front " two - parter , was awed by the look of the species . " " To see the prosthetic make - up on the alien Nazis ; it was just out of this world , no pun intended , " " she enthused . " " It ' s really , really amazing . " " ( ) On the other hand , production illustrator Doug Drexler commented that the two - parter " took some fan heat for ' space Nazis . ' " Apocrypha . The novel " Watching the Clock " has a faction of Na ' kuhl from the 29th century stealing a Deltan time perceptor in 2372 . It is unknown if it was the same faction that eventually fled to 1944 . As revealed in the " Star Trek Online " mission " Doomsday Device " , the Na ' kuhl visited the 22nd century in the hopes of enlisting the aid of the Klingon Empire in the Temporal Cold War . They enticed the Klingons with information about the future , including the location of a disabled planet killer , but the Klingons refused them . A small faction within the Empire passed the knowledge down through the generations , culminating in the retrieval and activation of the planet killer by Ambassador B ' vat ' s forces for use against the Federation . Later , the Na ' kuhl appear in the mission " Stormbound " , where Kal Dano and the player attempt to stop a group of Tholian s from destroying the Na ' kuhl star in the 25th century . Dano reveals that the Na ' kuhl do not have sufficient technology to repel a Tholian invasion at this point in time , but they will soon develop it . Although the mission is unsuccessful , the Na ' kuhl survive a harsh cooling of their planet . The Na ' kuhl would later blame the Federation for failing to save their sun , leading to their becoming a faction in the Temporal Cold War . Curiously , the Na ' kuhl System ' s star survived its dimming , against all odds .
