Revok
Gul Revok was a male Cardassian military officer in the 24th century Cardassian Union.  Revok was also a collaborator with the Dominion in the 2370s.

In 2375, he appeared willing to bring his and Legate Goris' forces, numbering some five hundred thousand, to the Cardassian Rebellion. However, Revok betrayed the Rebellion, resulting in the massacre of Goris' forces on Cardassia Prime and the annihilation of all eighteen rebel bases. He was observed by Damar who went to meet him, but Revok did not find him.

Weyoun later praised Revok in a speech broadcast around the planet, calling his actions "heroic." ()
