A Cardassian gul who promises to bring his forces over to Damar's rebellion in 2375 and instead delivers the rebels to the Dominion.
Gul Revok appears in the Deep Space Nine episode The Dogs of War. He commands troops on Cardassia Prime and sends word to Damar that he is ready to change sides, an offer that could give the rebellion a foothold on the homeworld itself.
Damar, Kira and Garak travel to Cardassia to meet him. They arrive to find the meeting place swarming with Jem'Hadar and the rebels who came to greet them being gunned down; Revok has sold them to the Dominion, and their ship is destroyed, stranding them.
At the same time Weyoun announces that every rebel base has been wiped out. The three survivors take refuge in the cellar of Mila's house, and from there set about turning Damar into a legend among ordinary Cardassians.
