Tiron

Tiron was a regular customer at Quark's on Deep Space 9. He was attracted to Kira Nerys, but she drove off his advances by claiming that Odo was her lover. Still obsessed with her, Tiron paid Quark for a holosuite program that featured Kira. When Kira discovered Quark's scheme she made significant changes to the program, including placing Quark's head on her body, much to Tiron's displeasure. (DS9: "Meridian")

Tiron was the first of many Star Trek roles for Jeffrey Combs. The name of his species was never revealed.
