Quark

Quark was a male Ferengi on Star Trek: Deep Space Nine.

The son of Ishka and Keldar, Quark traveled to Terok Nor with his brother Rom and nephew Nog to run a bar on the station. They remained as the Cardassians withdrew and the Federation took over, renaming the station Deep Space Nine.

Quark's Bar became the center of station life on DS9. Quark for his part participated in all manner of activities, some of which were less than legal. Even so Quark had his standards and there were some things even he would not stoop to. His time in the Federation led to his developing a sense of ethics that some of his fellow Ferengi lacked.

Quark had a rivalry with Odo that went on from the moment Odo became chief of security on DS9. Odo spent a great deal of his time short circuiting Quark's schemes and arresting Quark when he broke the law. Despite this the two men respected each other.

Even though Quark often acted like a jerk towards his family, in reality Quark deeply cared for his brother, nephew, mother, and his friends.

Quark remained on the station throughout the Dominion War and remained on board following the war. At the end of the war he was running a pool on who would be the next Kai of Bajor, something Kira Nerys quickly put a stop to.
