A Breen thot who seals his people's alliance with the Dominion in 2375 and commands their forces in the strike on Earth and the Second Battle of Chin'toka.
Gor appears in several episodes of Deep Space Nine's final arc, including 'Til Death Do Us Part, Strange Bedfellows and The Changing Face of Evil, played by Todd Slayton. Thot is a Breen rank, and like all Breen of the period he is seen only in a refrigeration suit and speaks in an untranslated electronic rasp.
He arrives at Dominion headquarters on Cardassia Prime to sign the treaty negotiated with the Female Changeling, handing over Worf and Ezri Dax as a gift. Its terms cost Cardassia territory, and Weyoun gives Gor access to information Damar is denied, pushing Damar towards rebellion.
Under his leadership Breen ships attack Starfleet Headquarters on Earth, and their energy-dampening weapon destroys much of the allied fleet at Chin'toka, including the USS Defiant. Thot Pran later takes his place.
