Mavek was a Cardassian officer assigned to Terok Nor, during the Dominion's occupation of Deep Space 9 from late 2373 to early 2374, during which time he frequently worked in the station's operations center. He routinely provided Major Kira Nerys with a raktajino when she arrived in Ops for duty. Mavek fled Terok Nor alongside his fellow Cardassians and Dominion allies during Operation Return. (DS9: "Rocks and Shoals", "Sacrifice of Angels") Mavek was played by an unknown actor.
