In the mirror universe, Odo was the officer in charge of running the ore processing center on Terok Nor until 2370. He had a strong desire for order and obedience, and ran the most efficient operation in the entire Klingon-Cardassian Alliance. He created the Rules of Obedience.
In 2370, Odo was killed by the Julian Bashir of the primary universe, who had been forced to work in the processing center for the Alliance, during a thorium leak that disrupted the center's operations. In the subsequent evacuation, Bashir shot Odo with a phaser set to kill, destroying the Changeling. Intendant Kira lamented his death, as he apparently was the only one of his kind. (DS9 episode: "Crossover")
The Founders knew of Odo's death when Bashir crossed into the mirror universe with Section 31 in 2386. At trial, Doctor Bashir was not found guilty in Odo's death as the Female Changeling determined that Bashir was merely defending himself. Doctor Bashir and the Female Changeling later met and theorized that the primary universe Odo may have originated in the mirror universe and switched sides with the Odo of the primary universe at some point due to their personalities and temperament. (ST - Section 31 novel: Disavowed)
- Disavowed also establishes that the Bajoran security guard whose weapon Bashir steals and uses to kill Odo was the counterpart of Cenn Desca.
