The Numiri were a spacefaring humanoid race found in the Delta Quadrant. In the 2370s, they were engaged in a war with the Banean species, with whom they once shared a homeworld. A paranoid and aggressive species, they would challenge any intruder who entered into the war zone. They make use of such advanced technology as regenerative shielding, their weapons were also equivalent of that of a Federation Intrepid-class vessel. Their vessels are small but advanced enough to stand up to an assault by a Starfleet vessel; however, their sensor technology cannot automatically detect the presence of a Starfleet shuttlecraft.
In 2371, Numiri agents attempted to frame USS Voyager crew member Tom Paris for their assassination of Banean weapons designer Tolen Ren. As by Banean law, Paris was forced to experience the memories of the murder every fourteen hours. The Benaen doctor who performed the procedure was the real murderer and a Numiri agent, who hid the data on Ren's weapons research in the memory engrams. If Paris suspected anything, he would have believed that the symbols were part of the procedure. Twice the Numiri assaulted Voyager to capture Paris, only to fail each time. Tuvok was able to divulge the truth behind the murders and the Numiri attacks. Those complicit in the murder were arrested and the memories removed from Paris, leaving the Numiri with nothing.
