Renegade Ferengi
These Ferengi assisted DaiMon Lurin in the take over of the Enterprise-D in 2369. They manned two Klingon Bird-of-Prey and beamed on board the Enterprise-D, where they were stationed on several locations on board, including the transporter room, main engineering, and the sickbay. They beamed dozens of crewmembers on the surface of Ligos VII and held some other as hostages on the bridge. The Ferengi were overpowered by the teenage Jean-Luc Picard, Keiko O'Brien, Guinan, and Ro Laren, with the help of Alexander Rozhenko. (TNG: "Rascals")

(TNG: "The Battle", "Bloodlines")
Waiter
