During the last Armada game he was able to make a peace treaty with the Romulan and Klingon Empire and was able to defeat his duplicate Locutus in battle now that the Borg have returned he has to face them once again.

During the Dominion War he was captured and was forced to fight Jem'Hader after his escape along with Worf, Garak and Dr Julian Bashir he was made Supreme Commander of the Ninth Fleet. He later became Chancellor of the Empire when his comrade and house member Worf fought Chancellor Gowron for leading Klingons to there death under foolish tactics and by doing so making Martok look bad.

The Borg Queen
The creator of the Borg Collective, the one voice and the mind. There are countless Borg Queens if one dies then another is activated a cycle that runs through the Collective. She was first encountered at the first battle to assimilate Earth, then when she went back in time to stop Earth first warp flight. One of the last times we see her was when Admiral Janeway infected her with a neurolytic pathogen which infected the Borg Collective. The Borg Queen has once again made another effort to take over the Alpha Quadrant but with Starfleet destroying the Alpha Quadrant Transwarp portal the Borg Queen was stranded in the Alpha Quadrant and the voice of the collective couldn't be heard. The Borg also has to fight off Species 8472 and return to the Delta Quadrant.
It is this Cardassian Gul that orders the Cardassians to attack the Federation reserve fleets and attempts to take over the Alpha Quadrant, and forms a business alliance with the Romulans and has to fight off the Klingon Empire. He had to delay his attack on the Federation to defend Cardassian territory from the Klingon Empire.
He has been assigned by Chancellor Martok to lay waste to the worlds in the Gultek System. And assists Martok from then on, he warns you if Martok is being attacked.
