Kazon-Nistrim
The Kazon-Nistrim were one of the most aggressive and violent Kazon sects, led by First Maje Jal Culluh. The Nistrim were once one of the strongest sects, under the leadership of Culluh's grandfather. Neelix described the Nistrim as the most dangerous branch of the Kazon Collective. () However, his descendants proved to be less capable, and the Nistrim waned in strength until by the 2370s they were believed to have fewer than seven ships, making them one of the weakest sects. ()

The Nistrim were first encountered in 2371 by the . It was with the Nistrim that Ensign Seska of Voyager attempted to illegally trade replicator technology in exchange for an alliance. The Kazon failed to integrate the technology into their ship, and the resulting explosion killed all but one of their crew. When Seska's actions (and her true identity as a Cardassian) were uncovered, she escaped to Maje Culluh's ship. Seska became Culluh's consort and closest advisor, her knowledge of Voyager and its systems proving invaluable to the Nistrim's efforts to capture the starship. ()

In 2372, the Ogla Kar compared the arrival of the  – "showing off your uniforms and displaying the markings of your Federation with no respect" – to that of the previous encroachments on Kazon-Ogla space made by the Nistrim and the Relora. () 

Later that year, Seska devised a plan for the Nistrim to board Voyager and steal a transporter module. Culluh and Seska hoped that the technology would allow them to form a coalition amongst the other weaker Kazon sects, such as the Kazon-Hobii, Kazon-Mostral, and the Kazon-Oglamar. The alliance never materialized after the module was destroyed by Commander Chakotay. ()

Later that year, further Kazon attacks on Voyager forced Captain Kathryn Janeway to propose an alliance with the Nistrim. Although Seska was amenable, Culluh's refusal to speak on equal terms with a woman abruptly ended these negotiations. Culluh subsequently attended the disastrous conference on Sobras with several other Kazon sects, Janeway, and the Trabe. 

While Voyager was in contact with the Trabe, its engineer Michael Jonas secretly contacted the Nistrim, attempting to negotiate safe passage for Voyager in return for delivering information and technology. Seska convinced Jonas to sabotage the ship's warp coils, which would lead to a Nistrim ambush in the Hemikek system. Jonas did as she asked, but their planned trap was discovered by  Tom Paris. Jonas was killed while attempting to sabotage Voyagers weapons in a battle with a Nistrim vessel. ()

The Nistrim's final attempt to capture Voyager took place at the end of 2372, when Seska sent a message to Chakotay informing him that their child was in danger. Investigating the signal, Voyager picked up Teirna, one of Seska's subordinates, who then maneuvered them into a trap involving a large Nistrim fleet. During the battle, Teirna detonated an explosive hidden inside his body, causing substantial damage to Voyager and allowing the Nistrim to take Voyager. The Kazon stranded the crew on Hanon IV. The ship was eventually retaken by Paris, with assistance from Talaxian forces and the EMH and Lon Suder inside the ship. ()
