- "I serve the Founders in all things".
Broca was a Cardassian military officer serving in the 2370s. Following the defection of Damar and the founding of the Cardassian Resistance in 2375, Weyoun chose Broca as the new leader of the Cardassian Union, promoting him from gul to legate. Unlike Damar, Broca was eager to follow the orders of the Female Changeling and Weyoun almost without question. (DS9: "The Dogs of War")
After the Cardassian fleet switched sides due to the destruction of Lakarian City, Broca pleaded with Weyoun and the Female Changeling to let him talk to the rebels to persuade them to remain loyal. Instead, Weyoun and the Female Changeling concurred that it was just as likely for the rebels to convince Broca to defect. Still shouting that he was loyal to the Dominion, Broca and his aides were taken outside Dominion Headquarters by the Jem'Hadar and executed. Ironically, this gave an opportunity for the Cardassian rebellion to penetrate the building and ultimately capture the Female Changeling. (DS9: "What You Leave Behind")
