Ezri Dax (mirror)

In the mirror universe, Ezri Tigan is an unjoined Trill member of the Terran Rebellion.

In the 2370s, Ezri worked as a freelance mercenary, taking paying jobs from both the Rebellion and the Klingon-Cardassian Alliance. She partnered with Brunt and was romantically involved with Kira Nerys. While members of the Rebellion criticized Ezri for her lack of loyalties, she said at least once that she was "loyal to her friends," which included Kira. Members of the Rebellion likely knew of her close ties with the Alliance, as Julian Bashir called her a "traitor," and Miles O'Brien failed to pay her for a job around 2375.

In 2375, in the employ of Regent Worf, Ezri came up with a plan to steal cloaking technology from the "real universe." The "real" Zek had been kidnapped by the Alliance, and Ezri suggested holding him ransom for a cloaking device. She crossed over to our universe and encountered Quark, who thought her violence was his Ezri Dax engaging in sexual roleplaying. Ezri convinced Quark and his brother Rom to steal a cloaking device from a Klingon ship while she waited in Cargo Bay 14 of Deep Space Nine. She then used a multi-dimensional transport to return to the mirror universe with the cloaking device... and, much to her chagrin, the two Ferengi.

Upon returning to the mirror universe, Ezri was taken prisoner by the Rebellion, but soon ousted by her partner Brunt. Along with Quark and Rom, they took Brunt's ship to rendezvous with the Regency 1 and deliver the cloaking device to the Alliance. Once there, Ezri was reunited with Kira, but the relationship was soon soured after Kira killed Brunt for insisting on compassion for Quark and Rom. She tried to help the Ferengi by freeing Rom, albeit temporarily, to install the new cloaking device. Afterwards, she killed Elim Garak to save Quark's life. Although she passed an opportunity to kill Kira, she declared her loyalty to the Terran Rebellion.

When the Regency 1 returned to Terok Nor under Rebel control, Ezri was debriefed by Commander Leeta. (DS9 episode: The Emperor's New Cloak)
