most ("The Changing Face of Evil"). After Worf joined Martok's house, Worf's son Alexander would be inducted into the house as well, as would Jadzia Dax upon her marriage Worf (the marriage was initially opposed by Sirella). After Jadzia's death, Martok would come to regard Dax's new host Ezri as a worthy successor to Jadzia and would consider her part of his house as well. Martok's first appearances on Star Trek: Deep Space Nine (in "The Way of the Warrior, Parts I and II" and "Apocalypse Rising") were actually the Changeling infiltrator posing as Martok. The real Martok did not appear onscreen until "In Purgatory's Shadow". The Mirror Universe version of Martok has only appeared in the novels. Unlike the regular Martok, who is an honorable and caring commander, the MU version is foul-mouthed, slovenly and cruel. He is eventually killed by the mirror counterpart of Klag, who assumes Martok's role as Regent of the Klingon-Cardassian Alliance.
