Grilka's Klingon bodyguard, who challenges Quark to a duel when the Ferengi wins her affection.
Thopok is the bodyguard of the Klingon noblewoman Grilka in Looking for par'Mach in All the Wrong Places. He is outraged when Quark, coached by Jadzia Dax and Worf in the rituals of Klingon courtship, begins to win Grilka's heart.
Thopok challenges Quark to a duel, a fight the untrained Ferengi seemingly has no chance of surviving. Worf secretly controls Quark's movements from a nearby room with a remote device, and despite a malfunction Quark defeats him. Thopok was played by Phil Morris.
