For the similarly named Benzite officer, please see Mordock.
Mordoc was a Ferengi who served under DaiMon Tarr about his Marauder in 2364.
Along with the rest of the crew, Mordoc participated in the theft of a T-9 energy converter from Gamma Tauri IV. Mordoc, along with Letek and Kayron, later beamed down to a planet in the Delphi Ardu system, after their starship was immobilized above the planet by a powerful force field. He and the other members of the Ferengi science team ambushed Riker and his away team during first contact with them on the planet.
During the encounter, he was disgusted by Natasha Yar, as not only was a woman allowed to serve on a starship, but she also wore clothes. He asked her to submit sexually. (TNG: "The Last Outpost")
Mordoc was part of Commander William T. Riker's memories while being infected on the surface of Surata IV and treated in sickbay. (TNG: "Shades of Gray")
