B'Etor is a Klingon noblewoman, sister of Duras and Lursa, known for her cunning and her flirtatious manner. After Duras's death, she and Lursa back their nephew Toral in the Klingon civil war of The Next Generation's "Redemption", relying on covert Romulan support led by Sela. The sisters later turn to arms dealing, appearing in Deep Space Nine's "Past Prologue". In Star Trek Generations they help Dr. Soran in exchange for trilithium technology and die when the Enterprise-D destroys their Bird-of-Prey.
