Weyoun 8 was activated shortly thereafter, and continued to oversee the war effort for the Dominion. He was initially unaware, however, that Damar had decided to turn against the Dominion and had arranged for Worf and Ezri to escape. Soon after, Damar publicly denounced the Dominion alliance and announced the first strike by the newly-formed Cardassian Liberation Front against the Dominion's primary cloning facility on Rondac III. With no means to clone Weyoun again until those facilities were rebuilt, Weyoun 8 was possibly the last of the Weyouns. He immediately concluded that was precisely the reason Damar had chosen Rondac as a target. (DS9: "Strange Bedfellows", "The Changing Face of Evil")
Weyoun ensured that Damar and his supporters paid dearly for this attack. Acting on the Female Changeling's orders, Weyoun had Dominion forces hunt down and execute Damar's wife and children. (DS9: "Tacking Into the Wind") Despite some initial victories, under the guidance of Kira Nerys, Weyoun's forces successfully waged a devastating counter-strike against the resistance, successfully destroying all eighteen rebel bases, as well as wiping out the sympathetic forces of Legate Goris and Gul Seltan with the help of collaborator Gul Revok. Having assumed Damar to have died in the attack, Weyoun publicly announced the defeat of the rebellion and the death of Damar. Much of the civilian population, however, having become disillusioned with Dominion rule themselves, were skeptical of Weyoun's claims. Indeed, Damar reemerged shortly thereafter and began rallying the people against the Dominion. (DS9: "Tacking Into the Wind")
After Damar's followers successfully sabotaged the planet's power systems, causing a planet-wide blackout, Weyoun proposed retaliation against the Cardassian population themselves, with the Female Changeling's approval. Weyoun then ordered the destruction of Lakarian City and its entire inhabitants of two million people, announcing its destruction on a planet-wide broadcast. Rather than forcing the Cardassians into submission, this act only motivated Damar to lead his remaining forces in an attack on Dominion Headquarters, as well as causing the Cardassian fleet, then engaging the Federation Alliance forces in the Battle of Cardassia, to switch sides against the Jem'Hadar and Breen fleets.
Enraged by this betrayal, the Female Changeling ordered Weyoun to begin exterminating the entire Cardassian population. This act of genocide led to the death of over eight hundred million Cardassians before it was halted.
With the Jem'Hadar and Breen forces having been driven back to Cardassia Prime, Dominion Headquarters was stormed by Damar's forces. Though Damar himself was killed in the assault, Elim Garak, Kira, and Ekoor reached the main control room, capturing the Female Changeling. Weyoun, upon hearing of Damar's death, mocked him and the devastation of Cardassia, prompting Garak to shoot and kill Weyoun. After the clone died, the Female Changeling mourned him to Garak, who had fired the fatal shot: "I wish you hadn't done that. That was Weyoun's last clone." Garak unapologetically replied "I was hoping you'd say that." (DS9: "What You Leave Behind")
