Bo-Katan Kryze

Bo-Katan Kryze fought in Death Watch, later opposed Maul, and spent the Imperial years trying to free Mandalore. She wielded the Darksaber, worked with Din Djarin, and led the reclamation of the homeworld from Gideon's remnant. She refused to take the Darksaber as a gift, then won it in combat so Mandalore would follow.
