Nunk

From Memory Alpha, the free Star Trek reference.

DaiMon Nunk was a Ferengi who stole a hologram projection of Lt. Reginald Barclay. He intended to use the hologram to kidnap Seven of Nine in order to steal her Borg nanoprobes so he could sell them for a profit. He hired a dabo girl named Leosa to seduce Barclay, in order to gain access to the Pathfinder Project and steal the hologram of Barclay. Nunk than sent the Holo-Barclay to USS Voyager, and he told Captain Kathryn Janeway of a plan to get the ship home by creating a fold in space and creating a gateway. Nunk planed to initiate a verteron pulse in the red giant star to open a geodesic fold to bring Voyager through the fold, which would kill the entire crew. Nunk's plan failed, when the real Barclay pretended he was the hologram, and told him that Janeway had discovered the plot. (VOY: "Inside Man")

Nunk was played by actor Michael William Rivkin.
