Fallit Kot
From Memory Alpha, the free Star Trek reference
Fallit Kot was a former business partner of Quark's who aided him in a failed scheme to capture a transport of Romulan ale in 2362. Quark gave up Kot to the Romulans to avoid serving prison time.
Kot finished serving his Romulan prison sentence in 2370. Soon after, he traveled to Deep Space 9 and attempted to kill Quark. However, the two entered into partnership again. He shot a Yridian partner of Quark's, Ashrock, and took the Rings of Paltriss that Quark had just given to him. He later took Jadzia Dax and Melora Pazlar hostage and forced them to take him through the Bajoran wormhole and into the Gamma Quadrant. He shot Melora with a phaser, but she was later able to disable the runabouts artificial gravity. Using her Elaysian ability to function in low gravity, she was able to launch herself into him, stopping his escape attempt. (DS9: "Melora")
