For the regular universe counterpart, see Libby Webber.

In the mirror universe, Libby Webber was a Terran operative working for the Klingon-Cardassian Alliance, posing as a member of the Terran Rebellion. Template:MU fell in love with her. When Kim realized she was an Alliance operative, he took vengeance upon her, spending hours with her in a cell on the Rebellion base in the Template:MU. He tortured her in various ways, including peeling the flesh from her leg. Template:MU later recalled that Libby's screams "seemed to echo throughout the caverns for days."
