Abhorrent Admirer: Dojo playing a small guitar and singing in episode 9 attracts a rattlesnake that he begs to not hurt him... needless to say, it wasn't planning on doing that to him, but Dojo runs away from it just the same.
Chase. While he can be violent towards the monks, even wanting to eat them on one occasion, he can still be civil and if he promises them something like turning Omi back to normal and allowing them to return home under the condition they beat him in a Xiaolin Showdown, he keeps it. Although it is averted towards Jack, Wuya, and Hannibal Bean what with all the insults he hurls at them, double crossed Bean, and almost killed Jack and Wuya with a live T-Rex (albeit indirectly).
Agony of the Feet: The end of "Royal Rumble" has the Xiaolin Dragons hefting a boulder up a cliff, throwing it up for the last stretch. Master Fung, supervising them, sidesteps to not get hit by it. After the monks leave feeling accomplished, Fung grumbles and the boulder moves, revealing he didn't manage to fully sidestep it.
Amazing Technicolor Battlefield: In episode 9, the Xiaolin Showdown appears to be done in space, surrounded by long strips of brick walls with windows, coming up from down below!
Amazing Technicolor Population: Omi and Dashi are bright yellow, and Jack is gray. In Jack's case he could have done it on purpose considering the few relatives we see of his are normal and Good!Jack sometimes seems to have a more natural complexion, however, whatever we see of his body (his arms when he's not wearing the usual costume and his hairy legs), it's still gray, so it still fits this trope.
Anachronism Stew: The Shen Gong Wu, possibly. For instance, how did Dashi make the Shen Gong Roo when he'd probably never seen a kangaroo at all? More egregiously, the Ying and Yang Yoyos are a little before their time.
Anime Accent Absence: Western example: Grey DeLisle uses her typical American pre-teen voice for Kimiko, although her character is born and bred in Japan.
Animesque: The show's Chinese setting, the constant face faults, the kung fu movie-like plot and the Asian-like art style. Not a surprise, since the show's creator is Chinese.
Art Evolution: The second and third seasons' animation improves significantly from the first.
Art Shift: The flashback of Guan's fight against Chase is shown in a sketchy, black-and-white, but otherwise more realistic art style.
Artifact of Doom: The Sapphire Dragon, the only wu we see that can act on its own, and easily one of the scariest. Its breath turns people into sapphire statues, which it can then control once it grows powerful enough. The Heart of Jong may also qualify.
As Long as There Is Evil: A theme at the ending of the series is that no matter how many times the monks defeat evildoers, as long as there are people in the world, evil will never truly be defeated. The last two episodes are even called "Time After Time" which implies this theme even more.
Master Fung says that evil is never defeated, it merely changes its path and form.
Atlantis: An aside mention from Master Fung revealed that Dojo is the main reason Atlantis sunk in the first place, due to being evil at the time. It later appears, is overrun with giant spiders, and is destroyed to lock the spiders away.
Omi defeats Mala Mala Jong by ripping the Heart of Jong out of him via Golden Tiger Claws
Belligerent Sexual Tension: Raimundo and Kimiko, even filling the correct charactertypes. Although the attraction is seldom played up, the episode "Dream Stalker" makes it perfectly clear that Raimundo is interested in Kimiko. The moments when Raimundo is announced as Shoku Warrior makes it pretty clear their's something going on between the two
Don't talk about how big or "dome-shaped" Omi's head is...not unless you don't value your eardrums.
Also, don't call Master Fung's proverbs and advice "cheesy".
Better to Die Than Be Killed: Used for a gag by one of Spicer's Jackbots in a gag for episode 9 - after seeing the Xiaolin Dragons easily total its compatriots, Clay stares at the last one menacingly, which then opens a small cover on its chest to press a small red button, at which it falls to pieces in a timely manner.
Big Ego, Hidden Depths: Omi, Raimundo, and Kimiko each get at least one of these, which are described in greater detail on their character pages.
Bilingual Bonus: In "The Apprentice", during Omi and Jack's showdown, the balloons show the Chinese characters 不, 是, and 中. Respectively, these mean "no", "yes", and "middle" or, "intermediary". The entire show is also this, having names and Chinese characters with certain meanings put everywhere in almost every episode.
Bishōnen: Chase Young. Especially 1500 years ago, in Time After Time, when we first see what he looked like when he was a Xiaolin monk.
Bittersweet Ending: While good would usually come out on top, in some episodes they weren't so lucky. The villains would end up winning a given Showdown every now and then, sure, but there are some episodes that really hit hard, such as "Chameleon", "Ring of Nine Dragons", and "Saving Omi".
Bizarrchitecture: A Xiaolin Showdown warps the competitors (and their friends) into a just-plain-surreal version of their surroundings.
Omi: I command you to spill your internal organs now!
Jack: What kind of sick people are you?!
Raimundo: I think he means "spill your guts".
Bolivian Army Ending: Has the whole rogue gallery outside of the monks' base, waiting to attack them. Though it's in no way a tragic ending, we all know the monks are gonna kick all their asses, and do it in style.
Book Ends: The very first Xiaolin Showdown in the series is fought for the Eye of Dashi. So is the very last.
Brain Bleach: Kimiko feels the need to wash her brain out when she learns Jack's been invading the group's dreams with the Shadow of Fear. All of the monks have this reaction when they walk in on Dojo clipping Master Fung's toenails.
Breaking the Fourth Wall: Literally. During the theme song, Dojo spirals in toward the camera before crashing into it. The screen shatters and falls away, revealing the next part. Also, in Episode 8 he tries hiding in the bars below the screen. It doesn't work.
Raimundo: Where have I heard that before? Oh, yeah. "Previously, on Xiaolin Showdown." (Raimundo holds open his eyes wider which shows the Xiaolin Showdown logo.)
(Everybody grins and gives a thumbs up or two to the camera.)
Breath Weapon: Dojo (though he needs a little fuel for it to qualify as a weapon) and the Sapphire Dragon.
Brick Joke: In "Citadel of Doom" Master Dashi and Dojo remember hiding a certain time traveling Shen Gong Wu, but have a hard time remembering where exactly they hid it. Dashi believed he hid it in Europe, but Dojo insists it was in Egypt. A few episodes later, they find the Sands of Time, a Shen Gong Wu that allows them to travel through time. Where was it located? Egypt.
In "Something Jermaine" when Omi and Jermaine are arguing with each other, Dojo puts a stop to it with a rant about a dragon that stole his yo-yo. A few episodes later, the group stumbles across Chucky Choo, a dragon who Dojo hates because he stole the family yo-yo.
Brilliant, but Lazy: Dashi is implied to be this at first; when Omi first meets him, he would rather sleep than help him. Also, Raimundo.
Butt Monkey: Jack, all the time. He's constantly abused by everyone, even people on the same team as him. Incidentally, the Monkey Staff is his favorite Wu.
Calling Your Attacks: Everyone, but also played for laughs with Omi and Chase's kung fu attack names. A few examples of many: Duck Flipping Burgers, Sparrow Eating Hot Dog, and Dogs Playing Poker.
Raimundo: Okay, they've gotta be making some of these up.
Call Back: Way back in season 1, Dojo laments that people keep stealing out of the Temple's Shen Gong Wu vault, and that they should really have a padlock put on the doors. 20+ episodes later in "The Apprentice", Master Fung is seen closing the vault—with a padlock.
Character Name Alias: Chase Young is known at least to a couple other characters as the Prince of Darkness...there was another guy who had the same alias as that. He was the guy who got kicked out of the big, shiny house by his dad and is also known as the "Father of Lies" and "The Roaring Lion."
In a Season 2 episode, Clay is seen playing with a number of dolls (most of them resemble Transformers dressed as cowboys, along with a dinosaur and a covered wagon). This is funny enough on its own, but they reappear in "Life and Times of Hannibal Roy" (Season 3, Episode 3) being played with by Raimundo, Kimiko, and Omi.
Chekhov's Gun: In episode 10, Dojo is notes a golden-star necklace Clay's father is wearing, saying it looks familiar to him. Of course, three minutes later in the episode, Dojo recognizes it's a Shen Gong Wu that must be inactive.
Chekhov's Skill: The monks are shown using Shen Gong Wu to play a giant game of chess in an episode during the second season. Two dozen episodes later, Raimundo plays a giant game of chess in a Showdown in which he uses the same Wu.
The Chosen One: All four were chosen to be Xiaolin Dragons and that concept has been brought many times over the course of the series
Clap Your Hands If You Believe: Le Mime can create invisible objects just by thinking about them. However, once he's made them, other people can also influence them, something Kimiko and Omi realize when Raimundo pretends to rattle the "bars" on the box, which they didn't know existed until then. Omi then imagines a door for them.
Water: Blue. Interestingly, Omi is often associated with cherry red (and yellow, obviously).
Wind: White, but also green. Raimundo has Green Eyes and wears predominantly white and green.
Fire: Red. Of course, Kimiko's wardrobe changes too often for her to be associated with a particular color.
Earth: Brown, but also green (brown doesn't make for a good color when Power Glows). However, Clay is often associated with sky blue, which may be related to his calm personality.
Combat Breakdown: The episode "Master Monk Guan" has the titular character and Chase Young do a unique mutual example in which they stop using their weapons in their fight. They wasn't any major reason for it, they just both did it.
The Complainer Is Always Wrong: Being something of a jerk, Raimundo gets this a lot, but he isn't always wrong, at least not in the traditional sense - typically, his "complaints" are sympathetic if not outright justified, and the others suffer for ignoring his concerns just as much as he does for refusing to compromise.
Raimundo seems to have a good memory - his subconscious in "Dream Stalker" contains nods to numerous earlier episodes (the mansion Wuya gave him, Kimiko's kimono and her outfit from "The Return of Pandabubba," and Hannibal Bean turning into the final boss from Goo Zombies 4, among others).
An example is in the episode "Shadow of Fear", Jack enters the temple to steal the Shen Gong Wu. Omi shouts "Jack Spicer!" and Jack replies "In the flesh." More famously, this is what Wuya said when she first returned to her solid form all the way back in episode 13.
Also, in episode 48, Chucky Choo is the dragon referenced in Dojo's story about the friend who stole his "family yo-yo", episode 36.
Jack: No, no, no! Gloating first, then we crush them!
Cooking Duel: The actual challenge of a Xiaolin Showdown can be just about anything, although the surroundings usually play a part.
Implied to be one of the rules, during the Xiaolin Showdown for the Heart of Jong, Omi is at first undecided about what the challenge should be, stating "a Xiaolin Showdown must fit the surroundings" before deciding on a game of collecting acorns.
Jack built one that turned into a mecha for the New York episode. Dojo briefly shapeshifted into an organic train to keep up with it, but he prefers to avoid doing so — that third rail really chafes.
In "Treasure of a Blind Swordsman", Jack robs the protagonists and makes his getaway on a flying train. The monks catch up later, leading to multiple fights atop the train.
Crazy Jealous Dragon: Dojo has certain issues with living apart from Master Fung for any length of time. Particularly evident when Fung temporarily hires a new female dragon assistant and when Good!Jack starts doing all of Dojo's jobs.
Creepy Child: Heylin!Omi while kicking Raimundo and Clay's asses. He gets even creepier when he speaks:
David Versus Goliath: A staple whenever Omi goes up against anyone (Jack's transformation bot, Vlad, Wu-possessed Raimundo), but special mention goes to his showdown against Cyclops. Cyclops is already a giant, but Omi was accidentally shrunk to the size of an ant beforehand.
Deadpan Snarker: Although he's not exactly deadpan, Raimundo is still quite snarky.
Deadly Dodging: It's not uncommon for the Xiaolin Dragons to do this upon Jack's robots. In Master Monk Guan, Chase Young pulls a rare villainous example on the Xiaolin Dragons.
Deal with the Devil: Chase Young and Hannibal Bean are prone to making these. In fact, Chase Young became evil by taking one from Hannibal.
Death Course: Apparently, they're standard protocol for Xiaolin training.
An ongoing part of the series revolved around Omi thinking he was better than everyone else and that he was the most deserving of becoming the new Xiaolin Dragon. Arguably, the two-part series finale was dedicated to showing how incredibly misplaced these beliefs were. Omi's special blend of ego and naivete caused nearly all of the problems in the finale, and although he ultimately righted the situation, it was only with Raimundo's determination, leadership, and planning that anything went right.
Defeat by Modesty: Omi beats Jack Spicer in the first episode's Xiaolin Showdown despite Jack's Shen Gong Wu being superior for the Showdown by managing to catch up to Jack due to him coasting along with his clear advantage, then gloating about how maybe Omi will respect him after he wins... and then getting pantsed by Omi who uses the time he spends being embarrassed and trying to pull his pants back up to get to the finish.
Dick Dastardly Stops to Cheat: Quite often, Jack Spicer tends to stop to cheat. This trope varies, as sometimes it actually helps, sometimes it doesn't.
Different in Every Episode: Kimiko's outfits and hairstyles. There's no explanation why she wears something different each time. She just does.
Ditzy Genius: Jack can build small armies of robots, transforming trains and a working time machine, but is laughably bad at being a supervillain and almost everything that doesn't involve robots. Of course, there is his Future Badass self.
Driven to Suicide: Essentially Dudebot, one of Jack Spicer's robots that Jack used the Heart of Jong to turn human. Soon finding out he doesn't really like feeling human, Dudebot takes the Shen Gong Wu out of himself and throws it away, and promptly drops down, motionless. Yes, this happened in a kids' show.
Dye Hard: In-universe, not only does Kimiko have an Unlimited Wardrobe, but also some kind of Unlimited Hair Dye Supply or Unlimited Wig Case (for most of the first season, her hair is a different color with her civilian outfit).
Easter Egg: A yin-yang is hidden in every episode.
Easy Come, Easy Go: The Shen Gong Wu change hands very quickly, preventing any side from gaining a real advantage. See Failure Is the Only Option. In one episode, Dojo is found to be confused about the status of all the Wu, attempting to chart it all down on a big whiteboard.
Jack Spicer himself works on a spreadsheet for who has what whenever a Wu isn't active. Dojo makes a similar attempt in a later episode.
When Jack creates Mala Mala Jong, it ends up using the Shroud of Shadows to ambush the monks, which surprises them because they (and the viewers) have no idea when Jack stole it (they won it, and had it the last time anyone checked).
Raimundo: Sounds like "end of the world" time again.
Hilariously lampshaded in episode 49
Master Fung: ... Their evil forces could cause the end of the world. Raimundo: Where have I heard that before? Oh, yeah. "Previously, on ''Xiaolin Showdown''." [Raimundo holds open his eyes wider which shows the Xiaolin Showdown logo.] [Everybody grins and gives a thumbs up or two to the camera.]
Enemy Mine: When left with no evil option, Jack Spicer will instead help the monks take out whichever Bigger Bad has achieved world domination.
Jack Spicer: I want to rule the world! Which I can't do if— Kimiko: —if Wuya's already ruling it!
Everything Is Big in Texas: Clay is a big guy who comes from Texas. Omi learns from him in the first episode that "it's not your weight, it's how you throw it around."
Everything's Better with Monkeys: The Monkey Staff gives you the agility and balance of a monkey, and an increasing number of other monkey attributes the longer you hold onto it (starting with a tail).
Subverted: Monkey!Jack is arguably more dangerous than normal Jack.
Everything's Better with Spinning: So much. Spirals are featured all over, with Jack's glasses, Wuya's eyes, Raimundo's medallion and clothes, both his and Kimiko's sequences in the intro and when they call out their element.
This is also what differentiates Omi's Tornado Strike from his Tsunami Strike, and one of the ways to use the Sword of the Storm.
Chase Young to Master Monk Guan thanks to Hannibal Bean. It's reversed during the Season Three finale, but not for long.
Chase Young to Omi. Both are talented martial artists, both honor their word, both have a bit of an ego, both are obsessed with being the best, and both live(d) in the shadow (if we go by Hannibal's word's to Chase and Omi and Raimundo's rivalry) of an older teammate who is both their best friend and rival. What sets Omi and Chase apart naturally are their choices. Omi strongly believes in the side of good and right, while Chase is a fallen hero.
Jack is this to Kimiko. Both are the highly intelligent and technosavvy children of wealthy parents and wish to prove themselves to their peers. One is however much more competent than the other...
Raimundo seeing himself in Jack's clothes demonstrates that he's aware of their similarities and is afraid he'll become like Jack.
Tubbi for Clay as well. Both are large and resourceful men who tend to show more intellectual thinking when they aren't expected to.
Evil Gloating: Jack's favorite pastime. Also indulged in by the other villains, though less so by the Big Bads, especially Chase Young.
Evil Is Dumb: Jack Spicer becomes this more and more as the series progresses. Nearly all the other villains avert it, and the main villains avert it with a vengeance.
Exposed to the Elements: Averted Trope by the Xiaolin Dragons, who wear winter clothing in cold places (though Kimiko still wears a skirt)... but not for Master Fung, who in "The Deep Freeze", wears exactly the same he always does aside from a tuque.
Master Fung: It has already begun: a thousand years of darkness!
Kimiko: Why a thousand?
Master Fung: It is actually 962 years, but "a thousand" sounds more ominous.
Face-Heel Turn: Chase Young and Guan by Hannibal Bean (but on separate occasions). Chase Young had his first out of immortality, but he's proven to be more evil than Hannibal Bean. Omi went back in time to prevent this. It worked, but it wound up making Guan making his face heel turn. However, Chase had no choice but to have a face heel turn himself.
The finales of the first two seasons focused on this happening to Raimundo and Omi respectively.
Flanderization: In the first season, Omi's sizable ego was clearly shown to be the result of his youth and lack of social skills. Basically, Omi is shown with underdeveloped empathy. Like a young child, he cannot view the world from any perspective other than his own. From the second season onward, Omi's ego became his defining characteristic rather than a side-effect of his other traits.
A specific example: Omi's "sexism" towards Kimiko was originally a one-off gag in episode 3 playing on his naivete. He had no idea that his words were offensive or even incorrect. In season 2, Omi developed an actual sexist attitude towards Kimiko and insulted her with full awareness that she would be offended, but only when he was jealous or mad at her for some reason.
Jack Spicer. In the first season, he struck a balance between being a credible threat (especially when he turned the Changing Chopsticks into an asset) and comic relief (his tendency to get cocky before losing a showdown). During the second season, he became increasingly ineffectual, whinier, and ridiculously hammier, and by the third season he spent more time becoming a dupe to other villains than a threat in and of himself (briefly saved by the finale, and then instantly reversed).
Flaw Exploitation: This is how Chase gets Omi to stay with him as his apprentice at the end of "Saving Omi".
Foe Romance Subtext: "Citadel of Doom" has Wuya say Dashi was a smart dresser in between saying he was a fool.
Funny Background Event: In "Time After Time", when Omi travels to the future, he finds Master Fung, Raimundo, and Kimiko looking very old and feeble, about to enter future old Jack's gladiator ring. Old Clay comments that they aren't the "lean mean fighting machines they used to be" while super old Master Fung easily defeats lions behind them.
Funny Foreigner: Mostly Omi, although each of the cast members have their moments.
Genre Savvy: Raimundo, who enjoys lampshading whenever it "sounds like end of the world time again."
When the monks fail to open the Treasure of the Blind Swordsman, Raimundo's Genre Savvy enables him to recognize that the blind old man was "talking like the Fung-meister". He subsequently figures out the koan and successfully opens the Treasure.
Go Karting with Bowser: After their team-up to defeat Wuya in the season 2 opener, Omi tries to convince Jack to switch sides permanently. Jack isn't persuaded, but suggests they go out for ice cream sometime when they're not fighting over Wu ("My treat."). Sadly, we never actually see this.
The Yin and Yang Yo-Yos separately also constitute revolving doors, which is played for laughs in "The Life and Times of Hannibal Roy Bean", when Kimiko challenges Wuya to a Showdown; they both use the Ying and Yang Yoyos liberally, causing them to constantly switch from good to evil and back again.
In the first part of the series finale the elderly Xiaolin Warriors during, and the alternate Chase in part two, allowing himself to become evil in order to help restore the timeline.
Good Jack does the same thing in "Finding Omi," allowing himself to be turned evil again in order to save the others' chi. During the same sacrifice, Good Jack uses the Ring Of Nine Dragons to split himself up into two, and one pulls another sacrifice for the other, holding back a monster in the Ying Yang World while the other retrieves the chi and leaves (turning evil in the process). This has the result of making regular Jack even more evil than usual, though in general it doesn't end up mattering much.
In the warped future where Guan has become evil and Chase Young is good, Chase agrees to turn evil to buy the Dragons time to find the frozen Omi and revert the world to normalcy.
Good Jack again in the series finale again, drawing away tigers so that the Dragons can escape.
Horde of Alien Locusts: The Giant Spiders from "Dangerous Minds". According to Master Fung: "The spiders are neither good nor evil. They are simply... consumers. They consume vegetation, animals, buildings, even the earth itself. They eat until there is nothing left to eat."
In addition, there is a Shen Gong Wu called "Moonstone Locust", which releases white, stone... locusts.
Hyperspace Arsenal: "Royal Rumble" has a sight gag of Tubbimura throwing out a bunch of weapons and food he was apparently holding, despite wearing nothing but skintight dark-purple clothes and a sword on his back while being very rotund, when he ends up on thin ice.
Ineffectual Sympathetic Villain: Jack, of course. Subverted in the first part of the series finale when he actually succeeds in taking over the world, imprisoning both the monks and the much more powerful bad guys.
Informed Ability: Hannibal Bean is made out to be the worst possible evil there could ever be, but he never succeeds in a single venture. Even his one accomplishment, turning Chase Young evil, didn't work out how he wanted.
On the other hand, he actually succeeded in causing a character to undergo a Face-Heel Turn (two, technically, even if one was in an alternate timeline) that they never reverted from, which Chase Young and Wuya had both tried and failed to do on multiple occasions, and is Chase's equal in combat when the two actually fight. So this may have some truth in it after all.
Intangible Man: The power of the Serpent's Tail, and one of the effects of Raimundo combining the Sword of the Storm and the Eye of Dashi.
Ironic Echo: In the same scene: after losing Omi back to the side of good, Chase Young claims that after tasting evil, Omi wouldn't be able to resist the next time, claiming "I believe the evil in you is stronger than you know." When Omi turns around and apologizes to his friends for not using the secret to defeating evil when he had the chance instead of abiding by his word, Chase admits that he caused Omi to see the secret to defeating good instead, and thus not abiding his word would have been catastrophic. Omi then points out that telling him that was uncharacteristically good of him, claiming "I believe the good in you is stronger than you know" and taking his leave.
It Can Think: On a couple of occasions, the Shen Gong Wu have acquired minds of their own. It's never been pretty. In one case, the Golden Tiger Claws possessed Raimundo, who had to be watched by Omi. Omi inevitably fell asleep, and the Claws helped keep Omi asleep (giving him a pillow, gently easing him down etc.) before setting off to do its deeds.
Chase Young. Hannibal Roy Bean also became this, as he first appeared in the disturbing and dark Ying Yang verse imprisoned in a maximum security cell and a dark suit of armour. While delivering a Hannibal Lecture to Jack Spicer.
The Sapphire Dragon, due to the fact that it's silent, doesn't lend itself as much to verbal humor, and tends to be rather creepy in its only two appearances.
Laser-Guided Karma: In "Bird of Paradise," the monks save a little old lady rather than try to capture the Bird. Guess what the little old lady turns out to be?
Leitmotif: Several. Omi has a very prominent one, and some other characters (like Wuya, whose is dark and sinister, or Good Jack, whose Tastes Like Diabetes as much as he does) have themes that occasionally play. In addition, all four of the Dragons get brief motifs in the theme song.
Lampshaded by Jack who tries to create his own theme and subsequently takes advice from Dojo on how to improve it.
Leeroy Jenkins: Raimundo in "Mala Mala Jong"; Even though Master Fung told the Dragons to take the Shen Gong Wu and leave the temple to protect them from Wuya's indestructible demonic warrrior, Raimundo goes back from the Dragons' hiding place to fight Jong, gets owned, and Wuya is able to find the Shen Gong Wu's location by entering his mind. This is why Master Fung does not make him a Xiaolin Apprentice at the same as the others;
Raimundo: But I was brave!
Master Fung: You disobeyed my orders. Your rash and impulsive actions almost led us to the brink of destruction. I am sorry, Raimundo, but you have proven you are not yet ready to move on.
Lethal Joke Item: The Changing Chopsticks give their user the ability to... shrink to the size of a rice corn. Jack uses them to steal almost all of the monks' Wus. Successfully.
The Changing Chopsticks see a surprising amount of use after that, often with surprising success. For instance, Tubbimura once used them to decrease his weight while on thin ice, thus winning the showdown against Clay.
Another example is using multiple Wu's in combination, making ones that were seen as useless into highly dangerous tools. During Raimundo's first Face-Heel Turn, he runs off with the newly acquired Reversing Mirror to give to Wuya. Later that night, he busts into the temple just to take only the Serpent's Tail. It takes the group a while to figure out, but freak out once it dawns on them that the two together can shift Wuya from useless ghost to utterly terrifying sorceress.
A lot of Shen Gong Wu play with this, along with Heart Is an Awesome Power. The Lunar Locket lets you control the phases of the moon: and is quite capable of putting the earth into an ice age. The Monkey Staff and Tongue of Saiping turn the user into a monkey and controls animals, respectively, and both have been used quite impressively alone and together. The Sweet Baby Among Us proves how well giant golden babies work, etc.
In the second episode, the monks are competing to get the fastest time on a circular obstacle course (the aim being to get past the obstacles and rescue a toy dog). Clay just turns around and picks it up.
Near the end of the first season, Omi and Jack have a showdown that involves holding a glass of water "without spilling a drop". Jack uses the Monkey Staff and holds it with his tail. After a few near-misses, Omi just swallows the water, catches up to Jack, and then spits it back into the glass once he's won.
Master Fung's jade elephant test. The goal was for the monks to grab the jade elephant, but when they get close to doing so Fung just smashes it, making them fail.
MacGuffin Melee: One of the central premises of the series, especially when the showdowns had mulitple players.
Magic Mirror: The Reversing Mirror. It has no effect in and of itself, but instead reverses the effect of another Shen Gong Wu. So when Wuya uses it with the Serpent's Tail...
Some episodes have shown it to have deflecting properties as well. This is usually limited to Wu effects, such as making the Eye of Dashi zap the wielder and not the target. However, it's also been used to deflect Evil!Dojo's flame, the Cyclops, and brain electricity.
Magic Skirt: Kimiko has one especially during the Dragon X-Kumai/Wudai Orion sequences (she's upside down).
Especially strange when she's in her Monk attire, where she actually wears pants (but it isn't noticeable due to how pale her skin is regardless).
Making a Splash: Omi's primary abilities. Also the primary use of the Orb of Tornami, so Omi uses it a lot.
Chase Young, who traded his soul for power and eternal youth. Hannibal Roy Bean, named for colorful Texas judge Roy Bean and, well, the fact he is a bean shaped creature. And even Master Monk Guan's name may be a reference to the general/war hero Guan Yu, who is famous in China for his role in the civil war that led to the collapse of the Han Dynasty.
Though more than likely an unintentional Bi Lingual Bonus, Omi is the Yoruba word for Water. Considering it's a Chinese character made by a Chinese creator it's strange he would an Nigerian word for a name.
Wuya is the Chinese word for "Crow" and during the third season, the only one of Chase Young's mooks that she made friendly with was the crow.
Mobile-Suit Human: Hannibal Bean's giant, spiky armor which he first appears in. He's quickly revealed to be only an inch tall. Then he gets the Moby Morpher and you only see it once again, as he's actually more effective as a giant version of his true self and doesn't need it.
Mooks: Well, it is a a fighting series. Jack Spicer's robots are usually the Butt Monkeys of the series.
Wuya: Why do you build these stupid machines?! They're useless!
Jack: Mom said I needed a hobby.
Moral Dissonance: The Xiaolin warriors once beat up Jack and stole his belt, shoe, a huge chunk of his hair and his underwear as part of a bet. And while the hair isn't really stolen, it becomes a little disturbing when you realized that Clay ripped it off of Jack's head.
Mundane Made Awesome: Often, the characters use flashy and over-the-top martial arts or magical skills to do fairly mundane things - chores, games, you name it. Applies to several of the showdowns as well, which brings simple contests into insanely impressive magical arenas.
Special mention goes to "Something Jermaine," where Jermaine and Omi have a fight which escalates into a competition to see who can eat dinner in the most impressive way. Point goes to Jermaine for stealing Omi's rice by bending his spoon and tossing it like a boomerang. In slow motion.
Mundane Solution: In the same episode as his Loophole Abuse, Clay wins a sparrow-catching showdown by gathering seeds for it while Jack flies around trying to grab it with the Third Arm Sash.
In the very first episode, several of Jack's robots are defeated by... hitting the off switch. Jack wonders aloud why he made it so obvious.
When Omi has to travel back in time and ask Grand Master Dashi for a replacement Panku Box, Dashi replies that he can have it if he can take it from him in a Showdown. After much effort trying and failing to defeat Dashi with fantastic martial arts stunts, Omi rethinks his strategy... and asks nicely.
The four of them are trapped in an (indestructible) invisible box by an Enemy Mime. How do they escape? By "miming" the act of opening a door, which opens an actual (yet still completely invisible) door out of the box.
Mundane Utility: Jack uses his Third Arm Sash to put a drink to his lips and juggle in the second episode.
In the sixth episode, he uses the Changing Chopsticks to shrink him down for easy construction of his robot's wiring.
The Xiaolin Dragons are hardly immune to this trope too - they use the Shen Gong Wu to complete their cleaning chores faster. In "The Deep Freeze", they use the Eye of Dashi to light a barbecue, the Fist of Tebi-Gong and Orb of Tornami to create a swimming pool, and Raimundo uses the Sword of the Storm to create a wave to surf on.
Never Sleep Again: During one episode, every time Raimundo falls asleep, a giant jellyfish monster attacks the temple and nearly destroys everything, then disappears instantly when he wakes up. After several sad attempts to keep him awake, he falls asleep again, the monster comes back and a sort of Battle in the Center of the Mind ensues.
New Powers as the Plot Demands: The Shen Gong Wu sometimes fall into this. For instance, the Reversing Mirror was specifically stated to reverse the effects of Shen Gong Wu, but was later used to reverse other kinds of attack as well. They even make the Changing Chopsticks' effects irreversible after a time limit, when Omi used them with the Changing Chopsticks.
Dojo: I hate to admit it, but, for an evil villain, you have been very hospitable!
Non-Standard Character Design: Omi is bright yellow, his head is perfectly round, his eyes are more along the lines of Black Bead Eyes than the Skin Tone Sclerae everyone else has, he only has one outfit as opposed to the Monk-wear and Casual-wear everyone else switches between and in that outfit his pants are black.
Clay: That's the second biggest tongue I have ever seen!
No Sell: When Omi returned to the past, the first time, to get Grand Master Dashi's help in defeating Wuya and Raimundo he is challenged to taking a pebble from Dashi's hand. None of Omi's attacks work as Dashi effortlessly avoids them all or is not phased when they even hit him. When the time is almost done, Dashi points out he has one option left: Asking Dashi for the pebble. It works.
Offhand Backhand: Raimundo is fond of this, even using it outside of its standard combat application (for example, he offhand-backhands a tree in "The Demon Seed" to jostle free the Wu in one of the branches, winning the showdown with style in the process).
Off Model: A couple in the theme song. When they show all the villains standing side by side near the end, Wuya becomes TOO expressive and looks waaaay too happy and her eyes don't even appear to have spirals. Before that, they show pictures of Chase Young's dragon form, Katnappe, Panda Bubba and Mala Mala Jong. The problem is with Chase Young, as his legs appear cartoonishly small and he looks as a result more lizard than dragon.
Offscreen Villain Dark Matter: Jack Spicer, probably. While he has been seen recycling parts from already-defeated bots, it's still not enough to answer the question of how he funds his endless waves of Jackbots. Chase Young also has this, as it's never raised how he ended up with such a lavishly built home.
Chase Young has lived for over a millenia and a half. He probably built the place with his own two hands out of boredom.
When Master Monk Guan first appears, he's revealed to be working for Chase Young. Chase had beaten him in battle and taken his spear, and Guan felt he couldn't be an effective hero without his weapon. He has a rematch with Chase at the end, and beats him without his weapon, proving that it isn't the weapon that makes the hero. He gives the spear to Omi, feeling like he doesn't need it. The next time he appears, it's revealed that he has several hundred copies of the spear and gives another to Raimundo. This little gag means that he basically sold out his principles for nothing.
At the end of Omi's first meeting with Dashi, he realizes that he has no clue on how to get back to his own time. Dashi says that they had a time traveling Shen Gong Wu, but recently hid it. Earlier, he used the Sands of Time to time his match with Omi. A later episode shows that the Sands of Time actually are a time traveling wu, which could have solved all of Omi's problems. Though it would be in character for Dashi to not give Omi the easy solution, it's never clearly established that that was his intention, and it also leaves open when he would have been able to tell Dojo not to tell Omi about the Sands true power.
Poster-Gallery Bedroom: Any shot of the Xiaolin warriors' bedroom stalls: Kimiko's has a large clothing rack and a desk with her electronics, Raimundo's is crammed with sporting equipment, Clay's has a handful of cowboy-related items, and Omi's has some minimalist Asian-esque decoration.
Psycho Serum: The Lao Mang Long Soup. Gives unimaginable power. Side effects may include: evil, loss of emotion, disfiguring mutation, metamorphosis into a monstrous creature (which results in dependency on the soup to keep oneself human), and a penchant for spikes.
Episode 10 has Omi pissing off a cow he's trying to milk and getting kicked straight out of the barn, four times. He exploits the pattern later in the episode for a fifth time, yanking on one of its teats to get himself kicked into a Jackbot.
Jack really doesn't like Wuya using how she's a ghost to pass through him. In the most feminine way possible. Wuya later basically does it to intentionally scare him.
Dojo getting and describing his afflictions which coincide with sensing Shen Gong Wu revealing themselves (such as, a rash). Kimiko usually protests it's Too Much Information.
The first time Wuya is returned to her normal form it's revealed that her "face" is a mask, but every time her sealing is shown she never has the mask, and when she returns to her ghost form the mask returns.
In "Time After Time" when Omi witnesses Wuya's defeat, it consists of Dashi, Monk Guan and Chase Young tearing through her rock golems like they were nothing and Dashi beating her in hand to hand combat without even really trying, without any suggestion of her Reality Warping magic or the alleged "furious battle" depicted in the first episode.
Shameful Shrinking: Once, when Raimundo's most recent joke fell flat, his entire head literally deflated and sank into his neck.
She Cleans Up Nicely: Kimiko in her kimono from the episode "Tangled Web" - although the moment (complete with eye-widening and gulping) actually happens in "Dream Stalker," when Raimundo sees her in his subsconscious.
Slapstick Knows no Gender: Or age, for that matter - all of the main characters, even Kimiko, get roughed up a fair bit both humorously over the top and not on a constant basis, in a medium which usually wouldn't use them for extreme slapstick, being teens and all.
Snowlems: The Heart of Jong creates an especially nasty one. "All that upper body strength and a killer Evil Laugh!"
Some Kind of Force Field: Averted with Le Mime - his boxes are constantly invisible, even when you walk into them. They're also soundproof, so Clay has no idea why the others aren't speaking until Rai goads him into walking into it. Rai then spoofs the stock phrase as he sees Clay's reaction: "It's...some...sort...of...in-vi-suh-ble-box. Ai, took him long enough."
Stealth Pun: In "The Emperor Scorpion Strikes Back", One of Jack's Ring Of Nine Dragons clones is a donkey. A jackass.
Stock Sound Effects: "The Evil Within" and "The Emperor Scorpion Strikes Back" uses the sound of TIE fighters moving for Raimundo charging and a Jack Spicer Ring of Nine Dragons clone charging, respectively.
Stone Wall: The Two-Ton Tunic makes the bearer impervious to all attacks, but its weight and encumbrance reduces their agility by a lot (though the Reversing Mirror can negate this drawback if used in combination with it.)
Strong Family Resemblance: In episode 10, Clay is symmetric to his father for a moment, both facing directly at each other with their sides facing to the screen. At that moment, they have the exact same-sized face with a similar round nose and underbite between them.
Stylistic Suck: In Hannibal's Revenge, the heroes need to build up Jack's confidence for their plan, so after faking several tricks they show him a movie of what the other villains really think of him. "Wuya" and "Chase" are quite obviously Omi and Clay each holding a Paper-Thin Disguise over their faces (and you can see all of Clay's head at one point when he let's the plate slip, "Hannibal Bean" is drawn on Kimiko's thumb, and you can see her face while manipulating him, and to add insult to injury Dojo walks through the background at one point and Raimundo tells him to stop ruining the shot. Jack is completely fooled.
Even earlier Jack replaces Kimiko with his Chameleon bot. Chameleon bot is ludicrously perky compared to Kimiko, repeatedly calls Jack Spicer "Hunky," and doesn't know basic things about Kimiko's life and routine that should have given her away instantly. The real kicker is that at one point Chameleon bot actually suffers from buffering, during which it verbally loads and processes data while unable to perceive the outside world. Naturally the Xiaolin Dragons are completely fooled.
Surprise Checkmate: Justified in "Oil in the Family" because the T-Rex isn't playing to win: it's trying to trap/knock out Raimundo with the giant chess pieces so it can eat him. Raimundo, meanwhile, is focusing on the checkmating the T-Rex to win the showdown.
Swallowed Whole: In Season 2 episode 7 'Enter the Dragon', Dojo becomes evil for 24 hours as he builds an overwhelming urge to collect Shen Gong Wu, turning into a huge two-headed dragon and swallowing the main cast in the process.
This Looks Like a Job for Aquaman: Several Shen Gong Wu are useful in very specific situations. Most notably the Gills Of Hamachi, which is the Wu to have for underwater adventures, but does Omi little good against Raimundo's more useful Fancy Feet.
The Sands of Time allows one to travel through time at will (which is why it's never kept by the monks). Omi travels back to the past in the first season finale, ended up Trapped in the Past coming back by The Slow Path.
Unresolved Sexual Tension: Kimiko and Raimundo, especially in the episode where Hannibal Bean intrudes Raimundo's head. He rests his arm on her shoulder in the cinema (only to find out that she is, in fact, Hannibal). However, since they never get together in-show, fans are left to guess on their own if it was resolved post-Grand Finale.
Although with the new series coming out soon, it's possible the results will be shown then.
Vanity License Plate: As can be seen in "Master Monk Guan", Jack has one that says NIL8 (as in, annihilate).
Verbal Tic: In "Hear Some Evil, See Some Evil", Kimiko can't stand the way Clay talks.
Clay: Omi, that's about as lowdown as a snake's bellybutton! Kimiko: Snakes don't have bellybuttons!
Jack: Now that I've defeated you, you'll respect the genius of...Jack Spicer!
Omi: Respect, THIS! [pulls down Jack's pants]
Villain Decay: Jack Spicer and Wuya, as both were upstaged by Chase Young, although Jack wasn't all that tough to start with, and Wuya was restored without her full powers. Even then, she can still beat all of the monks.
Reversed in the first part of the finale, where Jack's future self pretty much kills everyone.
We Win Because You Didn't: Master Fung challenges the monks to take a jade elephant from him, then takes out a mallet and breaks it when it looks like they're winning. This leads Omi to send the Golden Tiger Claws to the Earth's core at the end of the episode.
Welcome Back, Traitor: Raimundo, although he saved the day at the last minute. The other monks don't make too much fuss, although it's occasionally rubbed in his face, and part of Master Monk Guan's secret plan in a later episode involves him pretending to do it again.
WHAM Line: For the lead-up to the first season finale, Master Fung after Raimundo steals the Serpent's Tail.
Wouldn't Hit a Girl: Clay. It's usually his downfall whenever up against Wuya or Katnappe (though he could bear-hug the latter long enough for Omi to grab the Tiger Claws).
Raimundo: Clay, man, haven't you heard? Chivalry is dead.
"Yes"/"No" Answer Interpretation: Omi uses an object to split him into copies, which unfortunately suffer from Clone Degeneration. When one of the copies runs across a Shen Gong Wu as the same time as Jack Spicer, Jack challenges him to a Xiaolin Showdown. When the copy doesn't answer, he asks him he accepts. The copy just beeps his nose. Jack decides to take that as a yes.
You Will Know What to Do: Double subverted in the second season opening; Master Dashi's new puzzle box "will only open when the one who needs to open it, opens it." Everybody tries to open it, but it fails at a critical moment. Then Rai gives it a go, and it works.
