In the mirror universe, the Denorios was a pirate raider ship under the command of Captain Benjamin Sisko. The Denorios had a complement of ten crewmembers and was normally used by Sisko to attack passing ships for him to collect passing tribute for Intendant Kira Nerys and returned to its port at Terok Nor. In 2370, the Denorios later became the first ship in the Terran Rebellion Fleet following Sisko's rebellion. (DS9 episode: "Crossover"; VOY novel: The Mirror-Scaled Serpent)
