The main hero of the series. He is an archaeologist on a mission to search for - in order - talismans, demon portals, animals with talisman powers, Oni masks, and demon chi objects that were used to imprison Shendu's siblings. Though he's quite likely the only archaeologist on the planet up to this job (thanks to being Jackie Chan), he'd rather be on a dig or minding his Uncle's antique shop.
Slasher Smile: When Drew teases her one too many times after she tattoos herself with Tarakudo's brand, Jade flashes a particularly bloodthirsty grin, complete with her irises turn dark red, and summons some Shadowkhan to attack him. Fortunately for him, the bell snaps her back to her senses.
Waif-Fu: Works on school bullies, less so on demons and it also varies. In one episode she's easily beating giant mooks including one who easily floored Jackie and suddenly she's easily restrained by Finn, Chow or Ratso.
Jackie's uncle and Jade's great-uncle. Runs an antique shop that is more of a home base for the heroes than the high tech government agency. He's actually the cousin of (one of) her parents...they think.
Anime Hair: Look at his page image; it sticks up in several points.
Deconstructed in a Season 4 episode, when he was overly demanding and rude to Tohru (even more than usual), which caused Tohru to get mad at him, resulting in both not wanting to trade a word with each other. Later, when Tohru gets captured thanks to this, he realized how much of a jerk he was.
Pressure Point: If it's not a chi spell or kick, it's this. Again because it's a powerful art that can be used by old and frail people.
Running Gag: Hitting Jackie in the head with a two-fingered strike every time he does or says something wrong. He did this also to Captain Black, Tohru, Jackie's Dark Side, Daolon Wong, Hsi Wu, Super Moose, and, at least twice, himself.
Sitcom Arch-Nemesis: He has it with Kai Ching, Tohru's mother and Ms. Kimber. He takes these as seriously as Da Long Wong.
So Last Season: His knowledge of Chinese magic becomes near useless during season 4 due to the Oni being Japanese instead of Chinese like previous season villains.
The Smart Guy: When something magical happens, he's the only one with any idea what's going on.
Took a Level in Badass: When he used the Dog Talisman, which mentioned only in its first appearance makes the wearer as strong as they were in their prime as well as granting Complete Immortality. While he was already Badass, with the talisman he was nearly unstoppable, Hak-Foo only managed to hit him once in the entire episode.
Badass: He could at times he the better of Jackie in his early appearances, and after his Heel-Face Turn he also defeated the original three Dark Warriors single-handedly after Jackie struggled with them the entire episode.
Big Brother Instinct: To Jade. He at one point cautions Valmont, "If anything happens to her I will turn you inside out".
Big Eater: One of his defining traits (commenting that part of his Heel-Face Turn was hearing that Section-13 served donuts on Thursdays). In fact, the only time he didn't have an appetite was in "Pleasure Cruise" when he got seasick.
The Big Guy: As a good guy he is the big and heavy hitter for the J-Team.
Brick Joke: Tohru joined Section 13 because of an earlier episode, when Jackie suggested this to him on the statement that they serve doughnuts on Tuesdays.
Character Development: Starts out in the series as The Dragon to Valmont but then leaves The Dark Hand and joins Section 13. Over time, he also develops a close Intergenerational Friendship with Jade and starts a magic apprenticeship under Uncle, eventually becoming a powerful Chi Wizard in his own right.
Intergenerational Friendship: With Jade as he becomes protective of her after his Heel-Face Turn. It's surprising seeing as the first time they were seen together he wanted to cut her open since she accidentally swallowed the Rooster Talisman.
Beware the Nice Ones: Normally when the Tiger Talisman splits a person into good and evil twins, the good side is usually a sickeningly good wimp who is too scared to fight. In his case... it's just him as he normally is; a Badass.
Big Good: The Leader of Section 13 which is the vanguard of humanity against demons and evil human organizations alike.
Butt Monkey: Only Jackie and the Enforcers can top him here.
Contagious Cassandra Truth: After witnessing demons and magic first hand, he tries to report it to his superiors, but they decide he's gone crazy. He has to take Rorschach tests where he thinks all the images are demons!
Incorruptible Pure Pureness: After accidentally wearing an Oni mask, he is uncorrupted by it until Tarakudo tricks him into releasing Shadowkhan.
Morton's Fork: Before he believed in Magic, he was incapable of dealing with magical threats due to lack of Intel and expertise. After he was convinced magic existed, his superiors refused to believe him, questioned his mental health (especially when magical items went inert), and still didn't provide with the resources needed to deal with magic.
Overshadowed by Awesome: He's the badass leader to a secret agency equipped with state of the art weapons and scientific equipment, but compared to Jackie, his family, the J-Team and the supernatural villains, he just can't compare because they don't have a magic department.
The Rival: To Tohru in his initial episode. In his second appearance, they briefly get into another scuffle due to a misunderstanding, but after it was explained that Tohru was now good, they become close allies.
El Toro’s self-proclaimed “biggest fan,” who apparently is apprenticed under his idol. If El Toro is near, expect him to not be far behind.
Birds of a Feather: In most episodes, his personality is basically a slightly more jerkish version of Jade's. In an interesting example of this trope, rather than making them instantly get along it's usually thanks to this trope that they fight so much - but at the same time, they are able to drop it and be friends in a moment whenever they need to.
The Drag-Along: Though he is not necessarily unwilling and is generally quick on the uptake, it's usually Jade pulling him along on their adventures - especially during the J-Team episodes, where "Jade sneaks off with Paco in tow while the adults are distracted and saves the day" is a running gag.
Fanboy: Self-professed to be El Toro's biggest fan.
Hero-Worshipper: El Toro is Paco's ideal in both professional aspirations and daily life.
Hidden Depths: Shows how much of a hero he can be when he manages to break free from the Mind Control of one of the Oni Masks.
I am the keeper of the talismans. I am the apocalypse of which legend speaks. And I am, for once and for all, your executioner.
The fire demon and main villain of seasons 1 and 2, though he pops up sporadically throughout the show. Pre-series he was sealed into a stone statue and his talismans were scattered. Finding them is the focus of seasons 1 and 3.
Butt Monkey: Abused by his siblings for not trying to free them.
Chronic Backstabbing Disorder: Valmont, Dalong, etc. Anyone he works with he eventually betrays. The sole exception was his efforts to free his demon brethren, and that's largely because he was too terrified of them after the last time he betrayed them.
Genre Savvy: When reduced to a spirit and hit with a spell by the rest of the Demon Sorcerers to keep him bound in the first host he chooses, he immediately goes after Jackie to remove him as a threat. He's only stopped by Valmont kicking Jackie off a cliff, causing him to miss and hit him instead.
Hijacked by Ganon: Daolon Wong resurrected Shendu in season 3 so he can get the dragon talisman. This did not work out well for Wong.
Knight of Cerebus: Anytime he regains his true form is a cause for alarm, even when he became more comedic for most of the 2nd season. The only time this wasn't in play was when he was Back for the Finale, and he wasn't the Big Bad at that point.
Kryptonite Factor: Objects forged out of good magic like the Pan'ku Box. Even as a spirit touching it hurts him, and doing so for prolonged periods of time can knock him out.
One time he tries to kill Uncle and Section 13 to interrupt their incantation. It doesn't work.
One time he and the remaining Demon Sorcerers destroyed the components for the chi spells used to seal them.
Near Villain Victory: At the end of the first two seasons. He nearly succeeds in releasing his army of dragons, only stopped by Jade intervening in his fight with Jackie, and in the second, he uses the Book of Ages to rewrite history to erase the Demon Sorcerers' original defeat, and the only thing that reason he lost was because Jade tore out a piece of the book that happened have a part of her life on it, allowing her to retain her memories in the re-written history.
Not Quite Dead: Killed by Jade in the first season finale, but returns as a spirit in the second season and accidentally possessing Valmont. He's revived in season 3, but turned into a statue again.
Noodle Incident: While not outright stated, it's indicated that he managed to escape the netherworld and leave the rest of his siblings behind. It's never explained how he did that, but it's implied they helped him do so and he was supposed to free them, but he obviously ditched them in favor of ruling his old empire himself.
No Sell: Only magic or magic weapons can harm Shendu, which is proven when a rocket launcher and a highly powered laser failed to injure him.
Omnicidal Maniac: His plan at the end of season 1, release an army of dragons to destroy all of Asia.
Smug Snake: In season 2, where nothing goes the way he wants it to, he is constantly harassed by his terrifying siblings, and is constantly arguing with Valmont whose body he has to share (Valmont manages to knock him out- he was actually trying to kill him and risked his life to do it, just because he was sick of him). In season 3 he gets his Talisman powers back only to be immediately resealed, and after that is stuck as a prisoner of Section 13 until the finale.
You Have Outlived Your Usefulness: Shendu betrays Valmont and the Enforcers after getting all his talismans because he reasons that Dark Jackie was the one who brought them to him, not Valmont and the Enforcers (though he had been losing patience with throughout the season for their repeated failures). In season 2, he sends Finn, Ratso, and Chow out since they no longer needed to carry the Pan'Ku Box. Later, he tries to do this to Hak Foo, but Valmont doesn't want to be alone with him. He even lampshades it with Daolon Wong after backstabbing him.
"I may be a noble dragon, but I'm also a Demon Sorceror. And not known for keeping promises."
This suit costs more than your life.
Jackie Chan. Finally, we meet. It was nice knowing you.
The crime boss of the crime syndicate, the Dark Hand. He is also the main villain in seasons 1 and 2.
Badass Normal: Used Dragon on one occasion but otherwise he's bare handed in fights.
Demonic Possession: By Shendu. It's not full-out possession as Du was aiming for Jackie, resulting in Valmont and Shen-Du constantly bickering and fighting for control, as thanks to a spell Du was unable to leave until his siblings released him.
Demoted to Extra: From the third season onward. In season five, his only appearances are two brief, non-speaking cameos.
Diabolical Mastermind: He's the one running the Dark Hand, and the driving force behind the first season.
The Dragon: To Shendu in Season 1. He works for the dragon to acquire a promised treasure.
Enemy Mine: Twice. First when he wanted to get rid of Shendu from his body and second when he is turned into a kid by Daolon Wong.
Evil Brit: It is mentioned in one episode that he was originally an exchange student from the UK.
Grand Theft Me: In Season 2, when he is forced to share his body with Shendu.
The Heavy: To Shen-Du in season 1 because Shen-Du is a statue.
How the Mighty Have Fallen: The Leader of a high-class malevolent organization in the first season, reduced to a has-been dreaming of his former glory in the third and fourth seasons. By the fifth he became a bus driver with a brief, non-speaking cameo in the finale.
Kansas City Shuffle: After Shendu betrays him, Valmont plans to use him as a diversion for Jackie while he steals his treasure. Another one is after Shendu is killed by Jade, therefore losing his palace and treasure, Valmont finds the talismans for use in his crimes.
Villain Decay: He starts out as a very menacing leader of the Dark Hand and is surprisingly able to hold his own in a fight with Jackie in "The Rock." In Season 2, he becomes more of a Butt Monkey after Shen-Du's spirit enters his body and in the following season, Daolon Wong steals his employees and he is forced to commit petty crimes on his own. By the Series Finale, he has a cameo appearance where it is shown that he has been reduced to being a bus driver.
Even Evil Has Standards: Played with. Shendu asks they give him another chance by using the Book of Ages to escape from the Netherworld. They're initially against it, since they fear the book's reality warping powers, but agree to let Shendu use it since they realize their situation is desperate.
Eviler than Thou: All of them to Shendu - all of them, especially Bai Tza, regard him as a sniveling fool that only became as powerful as he was because rest of them weren't around. They push him around even more than they do each other, and Shendu - not in a good position to retaliate - fears their wrath.
Evil Old Folks: Tso Lan referred to himself as old, though all demons may count since they're thousands of years old.
Evil Overlord: They all had their own empires across the Earth before they were sealed, and had some time to rule them again when Shendu re-wrote history with the Book of Ages.
Genius Bruiser: All of them, given that they are demon sorcerors after all, though some are much more cerebral than others.
Glass Cannon: Unlike the rest of them, a solid enough hit will scatter Bai Tza into a puddle of water - which takes her some time to recover from.
Gravity Master: Tso Lan, the Moon Demon, and his "mastery of gravity".
Large and in Charge: All of them except Hsi Wu, who is still taller than most humans. The rest are about as big or bigger than Shen Du, and all of them make it very, very clear that they are his bosses, since he lost any equality privileges when he left them to rot in their prison. This is inverted with Po Kong, ironically, who is so lazy she is the least bossy demon despite being the largest by far.
The Bad Guy Wins: The episode which introduced both Eggbert (the noble rooster) and Mordecai (the noble pig) ended with him getting away with both talisman powers!
Black Magic: You don't see Uncle enslaving people to be his dark chi warriors.
Butt Monkey / Chew Toy: Almost every episode he's in usually ends up with him getting injured and final his defeat is the most humiliating of any of the Big Bads - he's stripped of his powers in a Curb-Stomp Battle and left to rot in prison. Likewise, most of his defeats are Humiliation Congas, with the episode involving time travel even having him rapidly flash through each of his most painful defeats.
New Powers As Plot Demands: Half the time he appears has him pulling out some new magic, sometimes something that he never uses again, like turning Valmont into a child or creating a giant ogre out of thin air.
You Killed My Master: States that he "defeated" Uncle's teacher Chi Master Fong (the details of which are never brought up). While the show has a Never Say "Die" policy, most dialogue indicates that he killed him.
Tarakudo & the Oni Generals/Oni Masks
I am the one and only King of the Shadowkhan!
This face will stare at you from the SHADOWS!
The main villain of the fourth season. He is the king of Shadowkhan and lord of all Oni. He has nine generals trapped in masks. Once they find a wearer, they can control their own types of Shadowkhan.
Body Snatcher: Once the mask's host uses their Shadowkhan, they begin to have equal control of the users body, whether the user (namely Captain Black, Finn, Paco, Jade and Valmont) want them to or not.
Brought Down to Badass: When Tarakudo is hit with a spell that causes him to have a body so that the tenth mask can be used to seal away him and the rest of the Oni, it also removes his Mind over Matter powers. And even without them, sticking the mask to his face proved the only way to stop them.
Butt Monkey: Despite being the most powerful of Oni Generals and being the sole named Demon General, Ikazuki is often at the butt of all jokes. First by being revived without a body, then by literally being at Finn's butt for his debut episode, and finally being "creamed" between Viper and El Toro's body slam.
Casting a Shadow: Summoning the Shadowkhan and spreading darkness are the main powers of the Oni generals.
Demonic Possession: When an oni mask is placed on the face of the user, they are still conscious of their actions, but are greatly influenced by the mask, and eventually it will completely take over. Finn wasn't affected because the rat talisman awakened Ikazuki who was accidentally placed on his butt.
The Dragon: In "The Demon Behind", Ikazuki, the blue/samurai Oni, is addressed as Tarakudo's second-in-command by Tohru. This comes into play in the fourth season finale, where Ikazuki orders the other Demon Generals to attack the Chans and remains with Tarakudo at Section 13 base during the Earth's invasion.
The Dreaded: Ikazuki is feared as Tarakudo's most fearsome general. Played for laughs as he ends up the Butt Monkey in all appearances- in his first, literally.
Intangible Floating Demon Head: Tarakudo. It makes him a very difficult enemy to fight, but also forces him to rely heavily on his minions. He still prefers it to having a real body, since the only way he would get that is if someone found the mask that can seal him away.
Heart Is an Awesome Power: The 'minikan' that one of the generals can summon. They're not demonic ninja like the others so they can't beat up enemies in a straight forward manner. However, they can eat the shadows of humans which not only makes them stronger but incapacitates the victim. As Tarakudo says, one has to make use of their particular strengths.
Living Shadow: The Shadowkhan, Elite Mooks who literally come out of the shadows. They have been around since season 1 but their role and backstory are expanded to be revealed as Tarakudo's private army, and come in eight additional varieties.
Mark of the Beast: If anyone has his mark they will have demonic powers and become evil.
Mind over Matter: One of Tarakudo's recurring powers is levitation through mind control.
Oracular Head: For most of season 4 Tarakudo is a floating head giving orders.
Outside-Context Villain: As the majority of the shows villains were Chinese in origin, none of the heroes were prepared for a Japanese one to appear. Even Uncle had no idea who he was he showed up.
Person of Mass Destruction: Once all nine demon generals are released, they collectively possess enough power to eventually cover the entire world in darkness. Presumably, if Tarakudo were not a floating head, he could do this all by himself.
Red Oni, Blue Oni: Personality-wise Tarakudo is blue to Ikazuki's red ("BEHOLD MY MIGHTY FORM!"), which is ironic because, in literal terms, Tarakudo and Ikazuki faces are red and blue respectively.
Sealed Evil in a Can: All of the Oni generals are trapped in masks and this is Tarakudo's ultimate fate. By extension, the Shadowkhan, control of which are the main reason the human villains want the mask in the first place.
Summon Magic: Each Oni general commands a tribe of Shadowkhan and, as per usual, can summon them at will. Shen-Du commanded a tribe of Shadowkahn because he magically manipulated one of their masks.
Time Abyss: Like the Demon Sorcerers, Tarakudo is ancient. The fact that Shendu used one of the Oni masks to summon the Shadowkhan, indicating they were defeated before he was turned into a statue, hints that Tarakudo might be even older than them.
Weaksauce Weakness: Onions are essentially kryptonite to the Oni. Even the nigh invincible Tarakudo will retreat once the vegetable is thrown in his face. However, a human/oni hybrid wearing a mask is immune. Surprisingly, onions are not the final ingredient to defeat him for good. His true weakness is the significantly rarer hair of a samurai.
Xanatos Gambit: The Oni generals are released whenever all nine masks are assembled in one place. Since Tarakudo is the only one that knows this, whether he gets all the masks, or the J-Team does, he still wins.
Shen-Du's Elite Mooks in seasons 1 and 2, barring a temporary lapse when a demonically possessed Jade seized control of them. Later revealed to originally serve Tarakudo, and to actually come in nine different forms, or "Tribes", of which Shen-Du's Ninjas were only one.
The Corruption: To anyone who summons them who isn't already evil, and sometimes even then. Notably its the summoning that starts it, not the Oni masks, as the corrupting only sets in once they are called upon. Though more noble-minded people can resist for a time, the oni's influence will dominate the host eventually.
Giant Mook: The Sumo Khan and, eventually, the Leech Khan.
Eldritch Abomination: The Squid Khan, who are the only Shadowkhan whose face we see, which turns out to be a hideous demonic-looking Cthulian monster. Presumably, all Shadowkhan are equally as horrifying underneath.
Elite Mooks: They are far more skilled and deadly than The Enforcers.
Fake Ultimate Mook: The Samurai-Khan. They're big, heavily armored samurai that wield shadow swords able to cut through anything, yet in the end they're just as easily defeated as the Ninja-Khan (or even easier). This especially jarring when compared to other tribes, like the Razor-Khan, the Sumo-Khan or the Crab-Khan, who gave the heroes an incredibly hard time (Crab-Khan in particular, since they were split in half). The fact that they're Ikazuki's Shadowkhan is a justification.
Mook Carryover: Inverted. They are introduced as serving Shen-Du, but originally served Tarakudo, despite the latter not appearing until season 4. Played straight with Shadow-Jade and to a lesser extent with anyone who put on a mask, though in both cases the summoner became Brainwashed and Crazy. Daolon Wong tried to do this, but ended up freeing Tarakudo instead, though he had briefly controlled them in an earlier episode.
Mundane Utility: Some people has used the Shadowkhan for something else than combat. For example:
When Jade got control of the ninja Shadowkhan in "Queen of the Shadowkhan", she used them as household servants.
When Ratso got the Razor-Khan Oni mask, he also used his Shadowkhan to play baseball.
Captain Black is a double subversion. When he got the Sumo-Khan Oni mask, he decided to replace all the Section 13 agents with Shadowkhan, claiming that they were better than humans in every way. We see several shots of Shadowkhan typing on computers, checking folders, arresting people...and moping the floor.
All that world domination stuff just doesn't pay the rent.
Shendu and Valmont's henchmen. It consists of Finn, Ratso, Chow, and Hak Foo. Tohru starts as an Enforcer but he has a Heel-Face Turn in the end of season 1, making Hak Foo replace him. Later, in season 3, they work for Daolon Wong and Tarakudo in season 4. But in season 5, when Drago employs them, he turns them down after they fail him once.
Agony of the Feet: Hak Foo has been known to scream "Crying puppy feet!" whenever he hurts his tootsies.
Badass Normal: Hak Foo dismisses supernatural aid because he has all the power he needs in his mundane skills.
Horse for healing? I am not easily injured. Rooster for levitation? I already fly. Dog for immortality? There is no one who can vanquish me.
Calling Your Attacks: Hak Foo is a case of Playing with a Trope. He does it straight, such as with his "Angry crow takes flight!" jump-kick; exploited by saying one and doing another; and averted: "Flying Monkey snatches magic box!" is not an attack but an observation. Most of the time this is played for laughs.
Cool Shades: For the first episode, Chow's sunglasses also acts as his glasses because of his near-sightedness. The rest of the time he can see just fine without the shades, even lifting them to get a better look at something.
Deadpan Snarker: Finn and Hak Foo both deliver snarky one or two liners to their allies or enemies.
Disco Dan: Finn has a number of times where he says "Get down. Get funky. It's the seventies!"
Elite Mook: Hak Foo is initially introduced as one - as a henchman far more competent than the others who is actually more than a challenge to the heroes physically. However, after a few appearances he eventually becomes less and less competent - though he is still presented as more dangerous than the others from time to time.
Evil Genius: Ratso who has several degrees in theoretical physics.
Promotion to Opening Titles: In Season 2, Hak Foo replaces Tohru as the character who gets punched by Jackie in the opening credits. In Season 3, he's absent from the opening again. He's seen with the Enforcers at Season 4's opening.
Superpowered Mooks: As Dark Chi warriors under Daolong, they gained enhanced physical abilities and magical weapons, and during their brief time serving Drago they gained fire powers. Also when they wore their oni masks as Chow managed to lift Tohru with one hand and toss him aside easily.
They Killed Kenny Again: All four as Daolon Wong's dark chi warriors. They POOF when "dying" they can experience lethal wounds as comedy, every single episode.
The Ice Gang
Drago's henchmen. It consists of Strikemaster Ice, DJ Fist and MC Cobra. Originally a pizza boy, Ice joined a monastery where he learned martial arts and met his boys Fist and Cobra. After they were kicked out of the monastery for bad behavior, the Ice Gang sought revenge but were stopped by Jackie and the Enforcers. They were later recruited by Drago and changed them into his dragon henchmen.
Genius Bruiser: Cobra and Fist managed to build a submarine out of broken cars in their junkyard hideout. It's possible that they built the monster trucks and tasers used to kidnap Jackie, Uncle, and Captain Black in the second to last episode.
Monkey King is a trickster monkey. Based on the Chinese legend Sun Wukong, he is released whenever someone pulls his puppet form's leg. The luckless victim becomes a puppet in his place, only to be restored if he pulls their leg, which he isn't likely to do of his own free will. He might seem like an irritating prankster at first glance, but he takes a very dim view of anyone trying to spoil his fun.
