"Lexx takes politically correct Star Trek-style sci-fi, murders its conventions, and then urinates on their graves."
— Star Destroyer Dot Net's Darth Wong on Lexx
- Alternate Character Interpretation: Stan in spades. Is he a dirty coward who will occasionally do the right thing when he thinks he has nothing else to lose? Or a hero whose resolve is weakened by self-hate? Also, is his sexism a personal flaw, or simply the result of him being raised in a society without any recognition of the importance of compassion?
- Big Lipped Alligator Moment: Several, even taking into account the show's general style. The usual reaction to a BLAM is the likely intention, too.
- Ear Worm: The Brunnen-G's fight song, so much so that it was made into the opening credits track for the audience's sake.
- It even becomes a big hit in Newfoundland.
- Fight Scene Failure: Happens when Kai takes out the mooks on the gondola in "May".
- Genius Bonus: The Higgs Boson apparently can't be measured without causing a planet to implode into a stranglet.
- Harsher in Hindsight: Pretty much everything, your second time through the show, due to the constant Apocalypse How.
- Those lusty babes looking for love at the end of "Love Grows"? If they weren't converted into Mantrid drones, they surely died when the Light Universe collapsed.
- But at least there's an afterlife, so they can live on after their death....! Oh, no, wait, that got blown up by the Lexx.
- Do you like your home planet of Earth, its thousands of years of culture and history, and all the quirky characters who live on it? Destroyed by a jealous robot head, and right after one of the heroes sacrificed himself to save it!
- Hilarious in Hindsight: Rutger Hauer and Brian Downey have essentially the opposite roles in "Eating Pattern" that they do in Hobo with a Shotgun.
- Hell Is That Noise: Throughout season 2, the Mantrid Drones' creepy, angry mechanical whining, and they swarm in the quintillions.
- Hollywood Pudgy: A research assistant who is smitten with Kai in Season 4, the disciples of "Woz", others. Tended to meet bad ends of the innocent victim variety, whereas anybody with supermodel proportions meets a bad end due to bad choices.
- Ho Yay Oh, Hoom Va Ray...
Viggo: Mantrid, I cannot live without you.Mantrid: You're being sentimental, my friend.Viggo: Mantrid, please!Mantrid: Viggo - I like you. I've enjoyed some of the time I've spent with you. (coldly) But I don't love you. I don't love anyone.
- Brother Trager falls in love with Stan in "Nook". It is completely one-sided on Trager's part, and Stan comes across as a tad homophobic in response. He does his best to let Trager down as gently as possible, however, and at one point genuinely considers making an exception for him.
- Another one-sided, but much more twisted, example occurs between Mantrid and his deranged assistant, Viggo.
- Xev and Bunny.
- Hollywood Homely: The female Hooker with a Heart of Gold in "Luvliner", others.
- I Am Not Shazam: You'd be amazed by how many people thought that Zev/Xev is named Lexx.
- Mondegreen: The chorus singing the Brunnen-G fight song embellishes certain syllables in odd ways, it's in a made-up language, and no official lyrics have really been released for it, so dozens of written versions are around the internet. However, the last episode is entitled "Yo Way Yo," which is the first line, and the track on the Brigadoom soundtrack is entitled "Jerhume Brunnen-G," the last line. Since the translation is known (Fighters fight the Fight / For their home and their heart / We fighters will win or die / Forever we are Brunnen-G) the third line must be based on the first, so it's likely "Yo Way Ra(h)." The second line is still a mystery and up to the listener's ear to decide.
- Moral Event Horizon: 790 comes close in Haley's Comet, but he finally crosses the line between unhealthy obsession and outright evil when he takes advantage of the Lexx's senility to trick it into blowing up the Earth, to prevent anyone on the planet from ever making eyes at Kai.
- Stan does this when he decides to blow up the Water Planet in Season 3 all to save the life of one woman. Prince even proves this when it becomes the act that gets Stan eternally condemned to the Fire Planet.
- Most Annoying Sound: "Bug Bomb, Malfunction!"
- This wasn't present on the original UK broadcast on Channel 5 and is thus, EVEN MORE ANNOYING.
- Narm Charm: The special effects.
- Paranoia Fuel: Pretty much the entirety of "Norb".
- Rescued from the Scrappy Heap: In Brigadoom, Stan is inspired by Kai's story and spontaneously grows a spine.
- Retroactive Recognition: Lucian Lacroix is Prince of Fire.
- Special Effect Failure: Most of the CG and blue screen effects in the first season are not convincing, and the same effects from the later seasons have not aged well (not to mention an extremely bad Chroma Key sequence when the crew are escaping from Mantrid's prison in the second season opener). As mentioned above, however, some see it as Narm Charm.
- Squick: Whatever is not Fetish Fuel for you ends up here.
- True Art Is Incomprehensible: Kai's living reincarnation in season four is an actor/performance artist whose own interpretation of Shakespeare's Henry V has to be seen to be believed, falling somewhere between preciously pretentious and "holy shit, did he really just do that?"
- Ugly Cute: Squish.
- The Woobie: Zev/Xev. For starters, her parents sell her to the Wife Bank as an infant, resulting in her spending her life being raised "in a box" by a hologram instructing her on how to be a submissive but sexually aggressive wife. When she is released, she is purchased by the parents of a Spoiled Brat to be his wife, but after hearing his insults directed at her appearance, Zev lost it and punched him in the face. She was then arrested and put on trial for "failing her wifely duties" and sentenced to be transformed into a love slave, and we all know how that turned out. To top it all off, the only man she's ever loved is incapable of returning her affections, both physically and mentally.
- Cleasby in "Prime Ridge". He overlaps with Woobie, Destroyer of Worlds given how much he loves his guns.
- Brother Trager in "Nook".
- The Dark Lady in "Woz".
