Yeggie was a Ferengi who assisted Nunk in a failed attempt to make a profit by kidnapping Seven of Nine to acquire her Borg nanoprobes.
Their plot was to send a false holographic image of Reginald Barclay to steer the USS Voyager into a geodesic fold that would kill the crew. The holographic Barclay was to capture Seven to harvest the nanoprobes. Their plot failed when the real Barclay fooled them into closing the fold before Voyager entered it. (VOY: "Inside Man")
Yeggie was played by Christopher Neiman.
The name Yeggie originated from the source's script.
