Memory Beta, non-canon Star Trek Wiki
For the primary universe counterpart, see Dominion.

In the mirror universe, the Dominion was much more tolerant and fair than its counterpart in the primary universe.

For example, in this universe when the Founders put the primary Julian Bashir on trial for killing the mirror Odo many years before, the trial was completely fair and just. This came as a shock to Bashir, who had expected to be executed no matter what. The mirror Female Changeling had a conversation with Bashir after the trial, and revealed that in the Dominion all trials are fair and just, with no one, not even a Founder, above the law in the Dominion.

The mirror Jem'Hadar were bigger and stronger than their primary universe counterparts and had less of a dependency on ketracel-white.

In addition, the mirror Vorta had even stronger psychic abilities than their primary universe counterparts, and were slightly more vicious. (ST - Section 31 novel: Disavowed)

Through a Glass Darkly[]

In another permuation of the mirror universe, the Dominion is even more savage and ruthless than its counterpart in the primary universe.

For example, the Founders of the mirror universe never tolerated the defiance of the Teplan people by merely inflicting them with the "blight". (DS9 episode: "The Quickening") 

Instead, they ordered the entire mass extermination of the planet's population by using a different biogenic weapon. Within two weeks, the inhabitants had perished to the last man, and the planet was cracked open to be mined of all its mineral wealth, leaving behind a completely dead world. Such a brutal act was intended to be a reminder to all who opposed the will of the Dominion.

Even the servants of the Founders differ in the mirror universe. The Jem'Hadar are larger, stronger, and even more suicidally devoted to their masters. As for the Vorta, they are far more vicious, and possess more advanced telekinetic abilities to use in their role as either diplomats or assassins. 

The mirror Dominion is even more aggressive and expansionist than its primary universe counterpart. (Decipher RPG module: Through a Glass, Darkly)


In 2381, a Jem'Hadar starship discovered the Bajoran wormhole. (ST - Mirror Universe novel: Rise Like Lions)

During a standoff between the Galactic Commonwealth and the Dominion in 2386, the two anti-Commonwealth agents Kersil Regon and Kort convinced Ambassador Zolim Fel Tun-A to have the Taurus Pact send three fleets towards the Bajoran system. Regon believed the Breen and Tholians were eager to see the Commonwealth's nose bloodied, and lured Zolim with the chance of salvaging advanced technology from the aftermath of a Commonwealth-Dominion battle. The Taurus Pact dispatched three fleets, one Breen, Tholian and Tzenkethi each. When the Dominion and the Commonwealth signed a non-aggression pact, the fleets retreated quickly, and Zolim was recalled to Ab-Tzenketh to answer for his fool's errand.
