- I Worship His Shadow
On Cluster, the capital of the league of 20 000 planets, a ship with the power to destroy planets lies waiting for it's master - "His Divine Shadow". But the soon to be executed rebel Thodin has his eyes on it too, and mangles the city's computer system while engineering his escape. Using the chaos that erupts, the death sentenced security officer Stanley Tweedle and the escaped "love-slave" Zev evade capture and eventually team up with Thodin... with the undead assassin Kai following, with orders to kill them all.
- Super Nova
Zev decides they should go to Brunnis, the original home of the Brunnen-G, in hopes of finding something that can prolong Kai's life. When they arrive they find it barren, except from holographic messages left by the eccentric "Poet Man". As they enter the library, they are totally unaware that back on the Lexx Giggerota has sprung back to life and plots to steal it with the help of the remaining Divine Predecessors.
- Eating Pattern
The Lexx is forced to land on a planet to eat and replenish its energy supply. While they wait, Stanley and Zev go outside to bury Kai, who seems to have run out of the protoblood that kept him functioning. On their way back, Zev insists on investigating a structure. Too late they discover that it is filled with insane people obsessed with getting "clean bodies" to make "pattern".
- Giga Shadow
Kai is running out of protoblood, and a desperate Zev forces Stan to set course back to the Cluster through the fractal core. When they arrive they find they entire planet barren - everybody killed in "the cleansing", in preparation of the birth of the Gigashadow.
His Divine Shadow's tyranny has been overthrown, and His order left in ruins. Chaos reigns in the light universe, with His Shadow's minions scrambling to find a place for themselves. One of these is His Shadow's bio-vizier, Mantrid, who plans to become immortal by transferring his consciousness into a massive computer.
Waking Kai can be a dangerous business, as Stanley Tweedle finds out the hard way. He is mortally wounded and, after some intense bargaining tactics on Zev's part, is rushed to the Medsat Medical Terminal. Here he is treated by the smarmy Doctor Kazzan who, to be fair, does indeed save his life. But along the way one ultimate sacrifice is made.
The Lexx picks up an unusual passenger: a shape shifting plant who takes on the appearance of a girl from Stanley's dreams. At the same time, some intrepid space explorers from the planet Potatoho have a run in with the Lexx. Kai invites them aboard, and some awkward first contact scenarios are played out. It's revealed that these boys are patriotic to a fault; they'll do anything for the glory of Potatoho. Needless to say, they don't exactly jive with the rest of the crew.
Let's face it, flying around the empty reaches of space without someone to play with makes for a frustrating time indeed. So when a signal is picked up from a nearby bordello satellite, its no wonder Stan and Xev are so eager to board. But the goods aren't exactly as advertised, and the den of iniquity turns out to be more of a pigpen. Still, Xev and Stan, accompanied by a reluctant 790, decide to indulge their desires.
It's all about effective marketing, isn't it? The Lexx picks up an advertisement from a television planet, and the crew just has to go investigate. They discover a world where they get to be the stars on various television shows. Their performances are judged by the finicky audience, who determine the ratings of the show. Too low and you get bumped down to daytime — as the no-talent Stan soon finds out. Kai also gets mixed up in the whole torrid affair and the crew decides once and for all that too much television is bad for your health.
- Stan's Trial
The Celes Pleasure Transport is the ultimate in high-class pleasure providers. Its four-star service makes the bordello satellite look like a pay-by-the-hour hotel room. So when Stanley gets the chance to pay a return visit to the curvaceous spacecraft, he's eager. But lying in wait for him are not the lovely escorts he's expecting, but a carefully laid sting operation.
- Love Grows
Three trash jockeys — to wit, a couple of greasy grubs and a grungy gal — cross paths with a giant and hungry insect —: the Lexx. Swallowed like popcorn, the ship and its cargo disappear into the belly of the beast. The crew manage to claw their way to freedom and into the arms of Xev. Before long, people begin to notice some ... rather unusual changes in their bodies and minds, and no one, not even the Lexx, remains unaffected — except for Kai, who's always a bit of a stick in the mud when it comes to this kind of fun anyway.
- White Trash
Even in space there are outposts with just a little less sophistication than others, a little less education maybe, a little less culture. Yes, even the light universe has its fair share of hillbillies, and four of them are discovered stowed away on the Lexx. Hiding from punishment on the Cluster, the family manage to keep themselves hidden, finally emerging when they become hungry. Quicker than you can say "hoe-down," the Lexx is hijacked and is en route for the planet Vermal.
The crew of the Lexx responds to a distress signal, and just in time — for Lyekka's awake, and she's hungry. The signal is coming from a downed prison-spacecraft on an inhospitable planet, and Kai, Xev and 790 set forth to investigate. The exploration turns up a decapitated cyborg, and several pods are found to contain prisoners, still alive but missing their hearts as a means of preventing escape. Lyekka makes quick work of some of them, and 790 secures himself onto — a body!
- Wake The Dead
Five teenagers are carousing around the universe when they decide it's time to take a nap. They oversleep by about 300 years. The Lexx comes across their shaggin' wagon and Xev can't help but go for a look. The teens are brought on board and, once roused, are determined to party. But jealousies and tempers flare and Kai is woken up in a most unpleasant fashion. What happens next is straight out of a slasher flick, as the dead man walking demonstrates why he was such a good assassin for His Shadow.
The Lexx and its crew discover Nook, a planet covered by water with the exception of one island, which is inhabited by a religious order of men who haven't seen a woman in 100 years. They follow strict rules and roles: scribes, for example, are only ever allowed to copy dislocated passages from disparate books, ensuring that no one Brother ever learns too much. Kai, however, suspects there is something he can learn from the archives of this seemingly perfect society, and intends to find out all he can ... and Xev learns what she's been biologically designed for ...
The strange young boy who appeared on the Lexx with the family of hillbillies is encountered again — this time floating through space. He is brought aboard the ship, and Kai observes he lacks "a certain vitality" — indeed, because Norb is no longer a little boy, but is composed of vicious drone arms — Mantrid's creations. These drones process everything they touch into more drone arms, and are impossible to contain.
Poor Stanley. He's always in some kind of mess. He's sick, really sick, and the only hope for him is to be found on Ruuma, an ugly little planet. Here live a decidedly dysfunctional family and their 792 robot, who comes complete with a medical diagnostic program. Once in service to His Divine Shadow, this macabre bunch now spends its time fending off the animated, former host bodies of that same evil tyrant. For Ruuma does strange things to the dead, as Kai's increasingly erratic behavior demonstrates ...
- Patches In The Sky
Gubby Mok operates the Narcolounger, a device that allows people to enter their own dreams. Stanley is keen to try the contraption, but Gubby's in a wee bit of an altered state himself. His operation of the chair is less than perfect, and Stanley's dream turns into a nightmare visitation from a cannibal woman, Gigerotta. Gubby joins Stan in the dream in an attempt to save him and Xev ends there too, and only Kai is left to figure out the mechanics of the ancient device.
790 announces that Xev has only 79 hours left to live — unless, of course, her clock can be reset. Trouble is, there is and only ever has been one Lustikon — or so they thought: another prototype is discovered on the planet Woz, in the hands of the Wuzzard, who promises to save Xev if Kai and Stan will do him one small favour: kill the Black Lady. Xev goes under the Lustikon's rays, but she's transformed into her original, ugly self and her time is still running out.
- The Net (1)
The universe continues to be consumed by Mantrid's drone arms. Stanley loses his hat, and ignores the Lexx's warnings about danger ahead. The ship violently impacts something: tentacles begin to invade the Lexx. Poor Stanley manages to convey a message to the crew: "cut cord Kai" and, chillingly, "hurry — it's killing us." Xev finds Kai imprisoned by a tentacle and sets him free, and for a while it seems all is well again. Things seem so rosy, that Xev even begins to consider Stanley as a possible bed buddy.
- The Net (2)
The desperate flight of the Lexx is interrupted by the appearance of a floating building. The strains of the Brunnen-G battle cry reach Xev's ears and her curiosity is roused. Xev, Kai and Stan find an empty theatre that springs to life when Stan knocks over a tambourine. The Master of Ceremonies informs them that a performance is about to begin, and since the theatre exists outside of space and time, they will be impervious to the encroaching doom that follows them. Musical drama then unfolds as the story of the Brunnen-G is played out in song: all is revealed in glorious musical fashion.
Faced with increasingly limited options for survival, the crew send out a distress call for help in the fight against Mantrid. At first it seems as if their prayers are answered when they get a response from none other than Brizon, His Shadow's former Supreme bio-vizier and Mantrid's mentor. But Brizon has his own agenda: first and foremost, prolonging his own miserable existence. This he does by gaining control over Kai and attaching himself in a most unpleasant parasitic fashion to Xev. He does, however, have a plan to stop Mantrid ...
- End Of The Universe
Mantrid's drone arms are everywhere, even inside the ship. Lyekka's pod gets damaged by the vicious things, and no place is safe. 790 is hooked up to a captured arm — and lo, the robot head-with-an-arm begins to create his own drone army. But it is too little too late. Even Lyekka does her best, but is no match for Mantrid. Finally, the crew manages to trick Mantrid into shifting all his drone arms — quadrillions of them — towards the ship. The resulting shift in mass and gravitational fields results in a reverse big bang.
- Fire and Water
The LEXX crew are awakened after four thousand years of cryo-sleep to find their nonfunctioning ship caught between two planets in a binary orbit. One of the planets, Fire, is entirely desert and the other, Water, is completely covered in water. Stan, Xev and Kai are soon drawn into the never-ending war between the two planets, and Xev falls in love with Prince (Nigel Bennett), the ruler of Fire.
A floating city on the planet Water has been attacked and destroyed by balloons from Fire, its orbit partner. May, the only survivor of the attack, is brought to the LEXX. Stan tends May's wounds and soon falls in love with her. But he cannot stop her slide towards death. However, Prince — ruler of the planet Fire — offers to cure her if Stanley will assist him, and a fateful deal is struck.
Stan is happy as his beloved May recovers from her wounds. Kai, meanwhile, arrives in Gametown, a floating city on the planet Water, in search of food for the LEXX crew. The buff young folks of Gametown seem to do nothing but play sports and take showers. Stan fails to fulfill his half of his bargain with Prince and loses May. Meanwhile, Fifi, a different sort of Gametown player, steals all the Moths from the Lexx, stranding Kai on the city.
Kai is stranded on Gametown, but escapes with the help of Bunny (Patricia Zentilli) to Boomtown — a place where the girls are gorgeous and the boys are buff and everyone has uncomplicated sex all day long. Kai is soon joined there by Stanley and Xev. Stanley finds everything he's always wanted, and more. But the utopia of Boomtown is destroyed as the city is attacked by forces from the planet Fire, using Moths stolen from the LEXX.
Stan, Xev, Kai — and a second living Kai they have picked up — find themselves together in a balloon over the planet Fire. Duke (Ralph Brown), one of the rulers of Fire, is also on board, with his sidekick, Fifi. But the balloon drifts over the Red Hot Sea and soon starts to descend. It is clear that not everyone is going to make it unless the lighten the balloon. And that means they have to make the difficult choice of who will go over the side to their death.
Stan and Xev find themselves in deep trouble in K-Town, a weird city on the planet Fire. They are almost rescued by Kai, but he has been damaged and ceases to function properly. Stan and Xev are unable to help Kai until they get some lucky assistance from someone who looks and behaves a lot like Mantrid (Dieter Laser), their former nemesis.
Xev and Stan lose Kai and wind up on the run in underground tunnels that lead from one city to another on the planet Fire. Unfortunately, the tunnels are populated by dangerous psycho-killers. The situation looks very bad until they are joined by Prince, who offers to help them if only they will help him. Xev rejects his offer, and the situation goes from bad to worse.
- The Key
Stan, Xev and Kai return to their ship, the LEXX. Stan wants to destroy the pair of planets they are orbiting, so that the LEXX can eat the chunks, allowing them to move on. But Xev distracts Stan from this plan with a sudden strong sexual interest in him. Stan fears that it's just a tease, but it is not. She gives him everything he wants — but in return she gains control of the "key" to the LEXX.
The LEXX crew discover a wonderful city on the planet Water called Garden. It is populated by cute women who pass the day nurturing tasty plants. They grow a special Lyekka plant (Louise Wischerman) for Stan, and he decides that his wandering days are over. Xev is not happy on Garden because it is devoid of men, but Kai finds a purpose. It is therefore agreed that she will go out on her own and that the trio will part ways as friends.
The LEXX crew are attacked by balloons from the planet Fire under the command of Prince. Their only Moth is destroyed and Xev is kidnapped. Kai captures a balloon and they then engage in battle with the other balloons. The slow-motion ballet of destruction ends with Xev being stranded on the burning desert surface of Fire and Stan and Kai escaping to the orbiting LEXX.
Stan and Kai search for Xev and find her footsteps crossing the inhospitable surface of the planet Fire. Her tracks lead to Girltown, a city populated by some very peculiar girls. Queen (Ellen Dubin) develops a strong interest in Stanley Tweedle, but his needs and hers turn out to be very different, indeed.
