Odo (mirror)

From Memory Alpha, the free Star Trek reference.

In the mirror universe, Odo was the officer in charge of running the ore processing center on Terok Nor. Odo had a strong desire for order and obedience, and ran the most efficient operation in the entire Klingon-Cardassian Alliance.

Odo was killed by Julian Bashir, 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. (DS9: "Crossover")

The mirror Odo, much as his counterpart, was played by Rene Auberjonois. Auberjonois liked the mirror Odo's uniform so much, he asked the producers to create a similar version for regular use on the series.
