Bo-Katan Kryze was a female Human who lived as a Mandalorian warrior during the final years of the Galactic Republic. Amidst the pan-galactic Clone Wars between the Republic and the Confederacy of Independent Systems, Katan pledged her loyalty to the radical Mandalorian splinter group known as the Death Watch, faithfully serving the group's leader Pre Vizsla as a trusted lieutenant. Ironically, she was also the sister of Duchess Satine, whom the Death Watch sought to usurp multiple times. After Vizsla was killed by Darth Maul, who claimed the title of Mandalore, Bo-Katan led a splinter group of Death Watch loyalists.
