Gor

Thot Gor was the representative of the Breen Confederacy to the Dominion in 2375. As the Dominion War grew to a stalemate in mid-2375, Gor was secretly approached by the Female Changeling for an alliance between the two powers. Seeing an opportunity for conquest, Gor travelled to the Cardassian Union to sign the treaty of alliance. (DS9: "Penumbra")

Thot Gor oversaw the Breen forces, quickly coming to outrank Legate Damar of the Cardassian Union in the Dominion hierarchy, an event which incensed Damar greatly. One of Thot Gor's first actions was the daring raid on San Francisco. He later oversaw the Second Battle of Chin'toka, which was a remarkable victory for the Dominion. (DS9: "Strange Bedfellows", "The Changing Face of Evil")

Following the retaking of Chin'toka, Gor was succeeded by Thot Pran as commander of the Breen forces. (DS9: "Tacking Into the Wind")
