The primary annoyance is evil Kira, known in the other universe as "The Intendant" of the space station. She is a narcissist who uses violence and threats of violence against "the resistance," (members include O'Brien, Bashir, and Dax) commoners forced to mine Cardassian ore in labor facilities on the station.
She also uses sex as a means to gain favor and parade her feminine wiles. She's the ultimate manipulator with no conscience. What she lacks in remorse she makes up for in charm, laid on thick and heavy in silver body-tight threads.
