The mirror-universe counterpart of Kira Nerys is the Intendant of Bajor, a vain and ruthless ruler of Terok Nor who oversees Terran slaves on behalf of the Klingon-Cardassian Alliance.
In the mirror universe Kira Nerys holds the title of Intendant and commands the station Terok Nor for the Klingon-Cardassian Alliance. Where the Kira of the prime universe is a blunt former resistance fighter, the Intendant is indulgent, theatrical and cruel, ordering executions on a whim while insisting that she dislikes violence.
She first appears in Crossover, when Kira and Bashir stray into her universe and she becomes fascinated by her own double. In Through the Looking Glass (2371) she hunts the Terran rebels and is outwitted by Benjamin Sisko, who is posing as his dead counterpart.
The Intendant returns in Shattered Mirror, Resurrection and The Emperor's New Cloak, gradually losing her position but never her talent for survival.
