A Klingon officer of the Klingon-Cardassian Alliance in the mirror universe, serving as Garak's subordinate aboard Terok Nor in the second-season episode Crossover.
Telok is a Klingon soldier in the mirror universe, seen in the second-season episode Crossover. He serves on Terok Nor, the Alliance's ore-processing station in orbit of Bajor, where he answers to Garak, the Cardassian second-in-command to Intendant Kira.
When Kira Nerys and Julian Bashir stray into this universe, Telok is among the Klingons who enforce the Alliance's rule over the station's Terran slaves, and he carries out Garak's orders without question.
He is also party to Garak's intrigue against the Intendant, in which the visiting Kira is to take her counterpart's place once she has been killed. The plot comes to nothing when Bashir breaks out, the mirror Sisko turns on his masters, and the two visitors escape back through the wormhole.
