Biography
Gwynyth Walsh is a Canadian actress best known to Star Trek fans for portraying the recurring villain B'Etor, one of the scheming and power-hungry Duras sisters. Alongside her onscreen sister Lursa (played by Barbara March), Walsh brought a unique blend of menace and charisma to the Klingon political landscape throughout the early 1990s. Her multi-series footprint across the Star Trek franchise spans several notable appearances.
