Vaadwaur The Vaadwaur were a humanoid species from the Delta Quadrant . Physiology . Vaadwaur were characterized by small ridges on their chins and two horizontal ridges just above their nose s . The ridges on the Vaadwaurs ' faces gave them very sharp features . A large fin - like crest ran across the center of their foreheads , becoming wider as it reached the tops of their skull s . Their hair grew from around the mid - region of their skulls , just where their fin ridges seemed to end . Neck ridges extended from their ear s , down along their necks , and onto their shoulders where they curled in towards the centers of their chests . This gave the neck ridges a cobra - like appearance overall , somewhat similar to Cardassian s . History . Prior to the 15th century , the Vaadwaur discovered and mapped the Underspace , a vast network of subspace corridor s that allowed them access to star system s throughout the Delta Quadrant . They used the Underspace for exploration , commerce , and conquest , earning them the envy and enmity of hundreds of species . The population of the Vaadwaur around that time was six billion . The Vaadwaur encountered the Borg during their travels , who at the time had assimilated only a handful of star system s . Another of the races they encountered were the Talax - ilzay , the ancestors of modern Talaxians , whose folklore included stories of a " " phantom army " " that appeared out of thin air and destroyed entire colonies before disappearing . In the old Talaxian language , " " vaadwaur " " was a word meaning " " foolish " " , appearing in several tales in Eldaxon ' s Collected Folklore featuring death and evil . Eventually , a coalition comprising the Turei and other species was formed to end the Vaadwaur threat once and for all . Their campaign culminated in the orbital bombardment of the Vaadwaur homeworld in 1484 , which was believed to have resulted in the extinction of the Vaadwaur . The Turei subsequently claimed the Underspace for themselves . A Vaadwaur battalion , numbering six hundred , managed to survive the attack underground in stasis unit s . Believing that the Turei coalition would quickly disintegrate after their defeat , they intended to reawaken in five years and reclaim one of their former colonies . However , a technical malfunction left them in stasis until they were discovered by the crew of the , 892 years later in 2376 , when " Voyager " was forced to land on the Vaadwaur homeworld to escape the Turei after they accidentally ' intruded ' into a subspace corridor and the Turei insisted that they be allowed to board to wipe " Voyager " s records of the trip . Having revived Gedrin after discovering his chamber , the " Voyager " crew awoke a large number of Vaadwaur and worked to find the Vaadwaur a new planet on which to rebuild . Frustrated by their antiquated technology and the encroachment of successors such as the Borg and the Devore Imperium on their former holdings , the Vaadwaur resolved to take control of " Voyager " instead . They were driven back with help from the Turei and Gedrin , who had come to disagree with their imperialistic ambitions after spending time with the crew . Fifty - three Vaadwaur vessels managed to flee into the Underspace , disappearing to parts unknown . ( ) A heavily - modified Vaadwaur assault fighter was later encountered by " Voyager " in . ( ) The Vaadwaur were mentioned during a briefing prior to " Voyager " s mission to retrieve " Friendship 1 " . ( ) A Vaadwaur was also encountered aboard the automated repair station in the 22nd century . ( ) Appendices . Background information . In the original script for " Dragon ' s Teeth " , the Vaadwaur went into hibernation for five hundred years . It would have made it more logical for their history to be nearly forgotten in Borg and Talaxian histories . ( " " ) Apocrypha . Though the Vaadwaur were not seen directly again by either " Voyager " or any other Federation or Delta Quadrant ships , Dr . Julian Bashir identified them as a threat to the Federation a few months after " Dragon ' s Teeth " and after examining the Pathfinder Project database in the " " novel " Abyss " . The Vaadwaur appear as a major antagonist in the Delta Rising expansion of " Star Trek Online " . Set roughly three decades after the events of " Voyager " , the Vaadwaur , using advanced technology provided by the Iconian s , have become a powerful military force known as the Vaadwaur Supremacy , intent on conquering the Delta Quadrant . The Vaadwaur nearly exterminate the Krenim , lay siege to Kobali Prime , homeworld of the Kobali , and come into conflict with the Delta Alliance , a coalition of Alpha and Beta quadrant powers ( including the Federation , Klingon Empire , and Romulan Republic ) .
