FALL OF THE REPUBLIC
During the time of the Clone Wars, Bo-Katan served as Pre Vizsla’s trusted right hand in Death Watch. The militaristic splinter group sought to restore Mandalore’s warrior past, an ideal which Bo-Katan held -- even if it meant ousting her sister, Duchess Satine, from office.
While Bo-Katan was loyal to Vizsla, she had reservations concerning Death Watch’s alliance with two beings they discovered in an escape pod: the Sith brothers Darth Maul and Savage Opress. Having found the Sith after they were soundly defeated at the hands of Obi-Wan Kenobi, Bo-Katan questioned the wisdom of joining forces with beings she deemed “no better than Jedi.” Maul Force choked her for the remark, but she remained strong in her convictions.
Following the Sith’s lead in a scheme to take over Mandalore, Death Watch became part of the Shadow Collective: an alliance with criminal organizations including the Pyke Syndicate, Black Sun, and the Hutt Clan. Vizsla, however, informed Bo-Katan that once the Shadow Collective assumed control of the planet, he would betray the Sith and claim the throne. As orchestrated by Maul, the underworld gangsters launched an attack on the Mandalorian capital city of Sundari. When all seemed lost, Death Watch swooped in to save the day and arrested Duchess Satine. With the staged battle complete and Mandalore won, Vizsla turned on the Sith. He jailed Maul and Opress, but was challenged to a death duel by Maul. After a vicious battle, Maul dispatched the Death Watch leader with a violent beheading; Bo-Katan refused to serve a Sith, and freed her sister from prison. Satine was recaptured, however, as part of a larger plot to lure Obi-Wan Kenobi to Mandalore. Finally, Maul had his revenge against his nemesis, and killed Satine before the Jedi’s eyes. Bo-Katan, while devastated at the loss of her sister, helped Obi-Wan escape from Maul’s clutches. She vowed that Mandalore would survive this terrible turn of events.
THE DARK TIMES
Following the Empire's occupation of Mandalore, Bo-Katan refused to surrender to the Emperor's tyranny. Years later, she joined with rebel Sabine Wren to help destroy an Imperial weapon that targeted Mandalorian armor. After their victory, Sabine gifted the Darksaber to Bo-Katan. She accepted, finally uniting Mandalore.
