<P> The Borg make frequent appearances in Star Trek : Voyager , which takes place in the Delta Quadrant , the region of the galaxy from which the Borg are believed to have originated . The Borg are first discovered by Voyager in the third - season episode `` Blood Fever '' . Chakotay discovers the body of what the local humanoids refer to as `` the Invaders '' ; which turns out to be the Borg . In `` Scorpion '' , the Borg are engaged in a war of attrition against Species 8472 , whose biological defences , developed as a feature of their evolution in fluidic space , are a match for the Borg 's nanoprobes . In one of the few instances of the Borg negotiating , in exchange for safe passage through Borg space , the Voyager crew devises a way to destroy the otherwise invulnerable Species 8472 . A Borg drone , Seven of Nine , is dispatched to Voyager to facilitate this arrangement as Captain Janeway refuses to allow the Borg to use neural implants for communication with the Voyager crew . </P>
