They kidnapped Worf and B'Etor took a liking to him and offered herself as a mate to him in exchange for his cooperation. They were supported by the Romulan Empire, who wished to see the alliance between the Federation and Klingon Empire fall apart. When Picard designated Gowron as the rightful Chancellor, she and her sister took up arms against Gowron.

B'Etor made a futile effort to seduce Picard. B'Etor attempted to convince him that Toral's challenge must be approved. In determining their claim, Picard went planet-side and paid an invited visit to B'Etor and Lursa. She staked Toral's claim just as Jean-Luc Picard, who was the Arbiter of Succession, was about to pronounce Gowron as Chancellor. Toral was the illegitimate son of their brother Duras.

She and Lursa supported their nephew Toral as the new Chancellor of the Klingon High Council. She was the younger sister, the more seductive (and more promiscuous) of the two. As sister to Lursa, B'Etor was one of the Duras sisters responsible for the start of the Klingon Civil War in early- 2368.
