Kai

Kai, Last of the Brunnen G, is an undead assassin on the science fiction television show "Lexx."

Warning: Wikipedia contains spoilers

Technically, Kai died 2008 years prior to the events of "I Worship His Shadow" in a raid against His Divine Shadow's flagship, the Foreshadow. The raid failed and His Divine Shadow destroyed Brunnis 2, the Brunnen G homeworld. Knowing all was lost, Kai rammed the command bridge. He was catapulted out of his small fightercraft and His Divine Shadow personally killed him. Instead of having the carcass incinerated, he had Kai de-carbonized and turned into a Divine Assassin[?].

For 2008 years, he served His Shadow, killing heretics and revolutionaries, until he was called to secure the Lexx from heretics. After a confrontation with Thodin, Kai found Zev Bellringer and Stanley Tweedle[?] on the bridge. However, he is called away to help the Divine Predecessors when a cluster lizard attacks them. When Kai picks up piece of the brain of the Divine Shadow that killed him, he regains his memories and joins Stan and Zev.

Kai is supported through proto-blood, a substance secreted by the Gigashadow[?]. This liquid reanimates Kai for limited amounts of time, so he must remain in cryogenic suspension.

Because he is dead, he lacks the ability to perform most bodily functions, a major let-down for Zev, who loves the dead man. He also lacks motivation and other emotions, and answers most questions with "The dead do not..."

At the end of the final season, Ismbard Prince[?], the former ruler of Fire, granted Kai life after promising it in a chess game. This was, of course, moments before Kai would sacrifice himself to destroy the Lyekka monster's ship that had destroyed the Earth. Kai had finally died, and he had died well.

Kai is played by Michael McManus[?].
