Nima was an Ennis woman fighting her rivals, the Nol-Ennis, on a small moon in the Gamma Quadrant.
She was always standing guard at the side of the Ennis' leader, Golin Shel-la, and was killed several times while the crew of the runabout USS Yangtzee Kiang was stranded on the moon. She was revived and her wounds were healed by tiny artificial microbes every time she was killed. (DS9: "Battle Lines")
Nima was portrayed by stuntwoman Patricia Tallman who received no credit for her appearance.
Her name was not mentioned in the episode but in the script for the episode. She was described in the script as a lieutenant of Shel-la.
