The Tonnika sisters were identical twins who became infamous con artists under the New Order. Individually, they were Brea and Senni Tonnika, although they often pretended to be just one woman, Bresenni. In 0 BBY, they earned additional fame for being in the Mos Eisley Cantina when Luke Skywalker first met Han Solo, but in fact, the "Tonnika sisters" in the Cantina were the Mistryl Shadow Guard warriors Shada D'ukal and Karoly D'ulin, masquerading as Brea and Senni in the course of a mission.
