The precocious Dragon of Water, Omi believes himself to be the greatest Xiaolin warrior and the leader of the team. Indeed, he believes himself to be the greatest warrior on the planet, period. Socially inept and comically oblivious, Omi's flaws are many - but his youth, his deep and abiding love of his friends, and his actual combat prowess make him loveable anyway.According to the Bird of Paradise, his finest quality is loyalty.
Big Ego, Hidden Depths: Many episodes (particularly ones where the Dragons have strained relations) suggest that Omi fears being alone and believes that if he is perfect, he will be surrounded by adulating friends and admirers.
Interestingly, this seldom overlaps with Chronic Hero Syndrome, as Omi's complete devotion to his duties as a monk can make him hesitant to help people not directly connected to said duties (such as with the old woman in "The Bird of Paradise").
Insufferable Genius: For all his bragging, Omi is indeed a talented martial artist with more training than the other monks.
The brash and impulsive Dragon of Wind, Raimundo appears at first glance to be cocky, irresponsible, and lazy, his primary concern being his own amusement. However, beneath his sly, sarcastic exterior hides a serious young man who is fiercely loyal to both his friends and his ideals, but also extremely frustrated with his own perceived failures.According to the Bird of Paradise, his finest quality is kindness.
Big Ego, Hidden Depths: Rai becomes angry whenever he feels helpless or inadequate, as shown during the events leading to his betrayal. It's straight-up stated in "Dream Stalker" that his lazy, jerk-ish attitude results from his fear of not being good enough and letting others down.
Hell, his development probably equals that of Omi.
Chronic Hero Syndrome: Despite his jerkish tendencies, Raimundo is always the first to put aside the task at hand to help someone in need, regardless of personal risk. However, this seldom overlaps with Honor Before Reason, which is generally reserved for Omi.
Cool Sword/Fighting With Chucks: Both the Sword of the Storm and the Blade of the Nebula are swords that can manipulate the wind (but can't actually slice anything). The Blade of the Nebula can turn into nunchaku for greater control and versatility in wind manipulation.
Beware the Nice Ones: Kimiko deeply cares for others, treats people with kindness, and tends to protect the boys, particularly Omi. That does not make her Hair-Trigger Temper any less terrifying.
The pragmatic, level-headed Dragon of the Earth, Clay is undeniably the nicest of the Xiaolin warriors. Like his element, Clay is steady, strong, and straightforward. Chivalrous and shy, Clay appears to most as a Gentle Giant - just don't mess with his friends or his hat.According to the Bird of Paradise, his finest quality is strength.
Mighty Glacier/Stone Wall: Like Kimiko, Clay can switch between these, depending on the situation.
From "The Journey of a Thousand Miles":
Clay: (Self-consciously tipping his hat after destroying a Jack-bot by letting it ram into his chest.) It's not your weight, it's... how you throw it around.
Big Good: Shared with Master Monk Guan. As the one of the two who appears the most, as well as the mentor of the monks, Master Fung is the one most responsible for the actions of the monks.
Blue Eyes: Interestingly, of the "light and watery" variety.
Batman Gambit: He acted like a Drill Sergeant Nasty to make Hannibal Roy Bean sway Raimundo to his side. After Raimundo pummels Omi in a Xiaolin Showdown, Guan makes Hannibal bet the Treasure of the Blind Swordsman against all their Shen Gong Wu, and Raimundo takes a dive. Thus, the monks got back the Treasure of the Blind Swordsman which had given Hannibal a huge advantage.
Big Damn Heroes: When he appears to defeat Chase Young in his debut episode.
Big Good: Shared with Master Fung. Although he doesn't appear as much as Fung, he is the most powerful good guy, able to fight equally with Big Bad Chase Young and all his efforts are in direct opposition to the seasonal Big Bad.
Mr. Fanservice: He arguably comes off as an accidental version of this trope.
Not So Harmless Villain: Omi is the one who keeps him in line even as a heel, so when Omi went to the future that limit is removed and ends up in a Bad Future which Jack Spicer's goal of World Domination DID come to pass and is able to even defeat ALL of The Heylin.
The true Big Bad of the first season, Wuya is a 1,500 year old Heylin witch who is more than a little irritated about being trapped as a ghost inside a puzzle box for much of that time. After Jack Spicer releases her, she guides him towards the Shen Gong Wu in an effort to regain her full power and mortal form (and subsequently take over the world). Ruthless and self-serving but also short-sighted, Wuya will betrayanyone to achieve her goals, except that one kid who betrayed her, oh what was his name again... The saddest part is that she actually DIDN'T SEE IT COMING!!!
I Gave My Word: Despite being evil, Wuya is actually quite honest and kept her end of her deal with Raimundo and truly gave him everything he ever wanted.
Even Evil Has Standards: Chase is a ruthless half-dragon Heylin Warrior who won't hesitate to turn Omi to the Dark Side or seriously injure Jack Spicer (at the very least, considering he once tossed said "Boy Genius" off a dangerously high cliff and threw a dangerously large boulder at him in another episode), but you can bet your life and college savings that when he makes a promise, he'll keep it.
Mobile Suit Human: His giant, spiky armor which he first appears in, but is afterwards revealed to be a bean. It appears again a couple of times in season 3.
Heel Realization: In the second episode he appears in, he is fighting Omi, but realizes that by fighting for Chase Young, he is actually fighting for the Heylin side.
Cut Lex Luthor a Check: Unlike other villains, who have grandiose schemes for world domination, Pandabubba uses Shen Gong Wu for relatively mundane, but illegal, money-making ventures, like arming his thugs with Wu to commit crimes or mind-controlling people into a workforce of slave labor.
Ambiguously Gay: The henchman in the white suit. It was even planned for him to say to the other henchman how much he enjoyed flying with him in the episode, but it got the cut, due to the very obvious implications.
The Vamp: She even managed to continue seducing Omi once the Xiaolin warriors knew she was the real villain. He only managed to keep complete focus after her true form was revealed.
