2008 years later, Kai is awakened by the most recent Divine Shadow in order to prevent the hijacking of the Lexx by heretics. During the fight, Kai regains his memories and his free will, and so joins Stanley Tweedle, Zev Bellringer and 790 onboard the Lexx.
Zev grew up in box at the wife bank on B3K. She was taught ways to please a man by holographic teachers. She had no contact with real humans. When she was finally ready to leave the wife bank, her husband called her a cow so she punched him. She became a prisoner of His Shadow where she was sentenced to become a love slave. During the love slave transformation her DNA was merged with a Cluster Lizard. The increased strength allowed her to break from her restraints. She made her way to The Lexx and escaped to The Dark Zone with the other fugitives.
