Zev of B3K is a major character on the television show Lexx.

When she "failed to perform her wifely duties," Zev was sentenced to become a love slave, a process done by a machine called the Lusticon. After a misshap with a loose cluster lizard and the Lusticon, Zev has some cluster lizard DNA inside her. And before the Lusticon could re-adjust her mind, she placed the head of a decapitated 790 robot in its path. The robot head (790) immediately fell in love with Zev.

On the episode "Terminal," Zev died, but was reanimated by Lyekka as a present for Stanley Tweedle. The new Zev (called Xev) has saved Stan on many occasions and once held the key to the Lexx.

Zev is madly in love with Kai, while attracting both 790 and Stanley, though she has no interest in them.

Zev was portrayed by Eva Habermann and Xev is portrayed by Xenia Seeberg ; Fat Zev/Xev was portrayed by Lisa Hines , in the original mini-series, and the un-lustacon Xev in the episode "The Wuzzard".
