One of the Ferengi who hijack Starfleet's hologram transmission to Voyager in Inside Man, hoping to lure the ship into a deadly trap and sell Seven of Nine's nanoprobes.
Nunk appears in the Voyager episode Inside Man. He is one of a small Ferengi crew, led by Gegis, operating from a ship in the Alpha Quadrant, who have learned of the Pathfinder project from the dabo girl Leosa, a former companion of Reginald Barclay.
The Ferengi intercept a hologram of Barclay being sent to Voyager and replace it with a version of their own. It promises the crew a quick way home through a geodesic fold, which would in fact kill everyone aboard.
Their aim is to recover Seven of Nine's body and sell her nanoprobes at an enormous profit. The real Barclay exposes the plan, and Nunk and his partners are tricked into shutting down the fold.
