Voiced by: Dante BascoAt thirteen (later fourteen) years old, Jake appears to be just your average skateboarding, comic book-loving teen. Unbeknownst to many, though, Jake is actually a fire-breathing dragon whose job is to protect a secret world consisting of leprechauns, mermaids, unicorns and other magical creatures.
- Achilles' Heel: According to Fu Dog (and Jake himself), Haley is this. Also, as a dragon, he has a weak point located behind the left ear.
- Act of True Love: In "Homecoming", he wishes Rose was never taken by the Huntsclan, sacrificing his chance to have a relationship with her to not only save her life but give her the normal life she wants.
- Adorkable: Definitely can have his moments, such as when he tries to do girl talk with Trixie or when he gets particularly lovesick in regards to Rose.
- Affectionate Nickname:
- His dad calls him "Jakers" and several other embarrassing nicknames.
- Trixie calls him "Jakie".
- Amazon Chaser: Jake excitedly comments he likes a buff woman, after he, Trixie, and Spud accidentally walk in on Rose doing an intense workout.
- Anime Hair: Justified and Lampshaded as a liberal use of gel.
- Anti-Hero: Mainly he acts like as a Knight in Sour Armor. His tendency to use lethal force against some magical creatures might boost him up to a Pragmatic Hero, however he only does this when the magical creature in question is exceedingly dangerous or tough enough to handle blows.
- Art Evolution: A pretty jarring case; in season 1 his dragon form is pretty big (resembling a Western dragon), but in season 2 his form is much more wiry. The second form is arguably the better design-wise, since it's closer to the depiction of an Eastern dragon and is true to both Jake's true build and personality.
- Battle Couple: With Rose. While they more often fight each other, there are still moments when they fight as a team, such as against the Aztec Guardian Serpent in the opening of "Breakout" or against the Chimera in "Dreamscape".
- Beware the Nice Ones: Normally, he's pretty laid back, but if you threaten the Magical World and make him think that his girlfriend has betrayed him, you just might end up being thrown into a steel elevator door.
- Big Brother Instinct: Does genuinely care for Haley, though it doesn't show up often. Nonetheless, threaten her and you will be in for a world of hurt.
- Big Eater: Shown to be this in "Furious Jealousy". Jake really likes his junk food.
- Breath Weapon: Fire, like most other dragons in the series.
- But Not Too Foreign: Half-Caucasian, half-Chinese.
- Catch-Phrase: "Dragon up!" and "Aww man!"
- The Chosen One: He's the first American Dragon. The theme song even calls him this word-for-word.
- Crazy-Prepared: Sometimes. Trixie couldn't tell if she was more disturbed from finding out he owns a leprechaun costume or that he brought it on the ski trip in which he didn't expect to have try and draw out Huntsgirl (he didn't know her identity yet).
- Dragon Ancestry: Jake is a dragon on his mother's side, and his grandfather and little sisters are dragons as well.
- Driving Test: In one episode, a magical creature turns Jake into an adult and he decides to take a driving test. His driving is so lousy the tester only passes him because he threatens to request the same tester for all next times he takes another driving test.
- Dude, Where's My Respect?: Not usually, but sometimes he doesn't get the respect he deserves, especially from Haley. At least until she tries his job for a while and realizes how hard it is...
- Fire-Breathing Diner:
- During Season 1, a random human sees Jake's fire breath and thinks Jake ate spicy food.
- One episode of Season 2 features Jake eating fries so spicy he needs his fire-breathing to cool down.
- Generation Xerox: He's a lot how Lao Shi was when he was younger.
- Half-Human Hybrid: Technically, as his mother is from a line of dragons (though not one herself) while his father is an average human. This doesn't seem to have any effect on his powers or the plot, though.
- Heartbroken Badass: "Half Baked". Played for Laughs, of course.
- A Hero to His Hometown: He is the local Dragon of North America and is regarded as such by the Magical Community there. Though, not always as much as he would like.
- The Hero: The main character and his job is to maintain balance between the human and magical worlds.
- Human Mom, Non-Human Dad: Inverted, Jake's Dragon Ancestry is from his mother, while his father is a mundane human. (Although his mother is technically "human" as well, because the power of transformation skipped her generation.)
- I Just Want to Be Normal: Enjoys being a dragon, but wants to enjoy all the aspects of growing up. Comes to a point in "Being Human" where he purposely gets himself in trouble to have his dragon chi confiscated so he can enjoy graduating middle school in peace.
- Inferiority Superiority Complex: "Family Business" implies that he has this, due to having a Child Prodigy for a little sister. Being the American Dragon is, in his own words, the one thing he's good at. So, when Haley begins her dragon training and starts outshining Jake, well...
- Instant Awesome: Just Add Dragons!: Obviously, considering that he can transform into a dragon.
- I Want My Beloved to Be Happy: A non-romantic reason for the breakup. Before Rose can fully sacrifice herself, Jake wishes that she was never taken by the Huntsclan. The result is her living a different life and their relationship being undone until she sees a picture of them from a dance and regains her other memories.
- James Bondage: He gets captured a lot. In one episode, he gets captured three times.
- Jerk with a Heart of Gold: Jake is cocky, caring, slightly rebellious, vain, loyal, lazy (occasionally), resourceful, and brave.
- Jive Turkey: This raised some controversy with his excessive use of street slang. Executive producer Eddie Guzelian admits that the bravado of Jake's character was shaped by Dante Basco's ad-libbing and their own writing, which was supposed to parody the "wannabe MTV gangsta" crowd. Naturally, it was toned down in season 2.
- Kid Hero: Jake is 13 (14 in season 2) and is The Hero.
- Love at First Sight: When he first meets Rose.
- Maybe Ever After: With Rose, thanks to the show being canceled while the two of them are living in different countries.
- Meaningful Name: The Chinese word for dragon is "long".
- Nice Job Breaking It, Hero!: A lot of conflicts resulted from him not taking his job seriously.
- One Head Taller: Inverted. Rose is a little taller than him.
- Power at a Price: In one episode, Jake drank a potion that temporarily gave him shapeshifting powers. Until it wore off, he couldn't use any of his other powers.
- Red Is Heroic: Jake's signature outfit includes a red jacket, and his scales are red in his dragon form.
- Secret Identity: Downplayed, his identity of the American Dragon is only secret to the Huntsman. Most of humanity are kept in the dark about magical creatures and he has no problem transforming in front of antagonistic magical creatures.
- Socially-Awkward Hero: Fighting magical monsters he can handle. Talking to pretty blonde girls, not so much.
- Star-Crossed Lovers: Once again, with Rose.
- Teens Are Short: Quoth Nigel:Nigel: You don't reach my knees on the b-ball court, why's a kid named "Long" got to be so short?
- Tiny Guy, Huge Girl: The Tiny Guy to Rose's Huge Girl. Justified as they are middle-schoolers and girls are usually taller than boys at that age.
- Wake Up, Go to School, Save the World: Deconstructed: He has serious trouble at balancing his schoolwork, his social life and his duties. The episode "Being Human" implies that he's really stressed due to this (Haley can't even start to guess how he does it).
- An episode did show him attempt to balance this via chi dopplegangers, but he did so via shortcuts (a chi amplifying dust.) After he grabbed the wrong one and made a bad chi clone, he reabsorbed them and managed to prioritize what he needed to along with getting his friends to help. However, it is still a great deal of stress and when taking everything to account, he does an admirable job as a hero and magical defender, doing better than what could be realistically expected out of someone in his position.
- Why Did It Have to Be Snakes?: Says this word-for-word in "Bring it On".
- You Gotta Have Blue Hair: The top part of his hair is green. Justified by the incredible amount of hair gel he uses.
Voiced by: Keone Young
- Badass Grandpa: Jake's grandfather who can turn into a dragon.
- Broken Ace: A very powerful dragon and the only one to defeat the Dark Dragon singlehandedly. However, his carefree life style and attitude was gone and he ended becoming a serious old man.
- Does Not Like Shoes: There's a few scenes (especially Season 2) where he's shown to not even wear his sandals.
- Foreshadowing: He tells Jake not to flirt with a mortal enemy (Huntsgirl/Rose), going on to say "Trust grandpa, he's been there". Skip ahead later in the season and we learn he was talking about Chang.
- For Your Own Good: Although it was never revealed to Jake or any other of the characters, this was the reason why he asked Rose to break up with Jake.
- Miniature Senior Citizens: Jake's grandfather is so small several people during the Halloween Episode mistook him for a kid dressed like an old Chinese wise man. Then again, it was shown in flashback he wasn't much taller than that during his prime. Susan should be glad the dragon powers weren't all that skipped her.
- Not So Above It All / Not So Different: He was just like Jake in his youth. In fact, he retained the attitude (but was cockier) as a young adult until he defeated the Dark Dragon the first time.
- This is probably why he's hard on Jake; he doesn't want his grandson to repeat his mistakes.
- Overprotective Dad: He had an enchanted compass to spy on Jake's parents when they were dating.Susan: Daddy! How could you?
Lao Shi: My darling, I may possess all the magic and strength of a great dragon warrior, but I am also a single dad.
- Politically Incorrect Hero: "Hero of the Hourglass" shows that he is not above prejudice against humans, seeing as he didn't approve of Susan dating Jonathan because, you guessed it, he's human. Granted, he does come around after he sees Jonathan standing up to the Huntsclan. Though it's also suggested he just doesn't like Jonathan specifically and/or didn't think he was good enough for Susan rather than just because he was a mortal. He's shown to respect other mortals like Jake's friends well enough in the present, yet still doesn't really care for Jonathan much.
- Wax On, Wax Off: Some of his training techniques.
Voiced by: John DimaggioA 600-year-old talking Shar-Pei, Lao-Shi's only companion and Jake's Animal Guardian. In the 1970s, Fu was a womanizer and a petty thief, but after meeting Lao-Shi, he turned his life around. He's messy and loud and he gambles and harasses women. However, deep down, he has a good heart and is a good, trustworthy friend to Jake.
- Big Eater: "Two words: I'M HUNGRY!"
- A Day in the Limelight: He got three of them; "Fu Dog Takes a Walk", "Fu and Tell", and "Nobody's Fu".
- The Gambling Addict: He'll frequently make bets or have a bet he's made in the past come back at the worst possible time. Not even near-death has helped curb it.
- Good Old Fisticuffs: Strong enough to send Yan-Yan flying across the classroom.
- Heel–Face Turn: He was a petty thief in the 1970s until he befriended Lao.
- Hyperspace Arsenal: We've seen him producing a lot of things from his wrinkles, ranging from lesser things like cell phones and shoes to anvils.
- Jerk with a Heart of Gold: Fu's a chronic gambler, womanizer, and full of obnoxious puns and one-liners. That said, he's a devoted member of the team and always there to provide Jake with some emotional support and advice.
- Lovable Sex Maniac: He's about as much of one as a G-rated Disney cartoon will allow. He squeezes a giantess' hump, gets excited when it comes to zipping up a woman's dress, asks a sprite to shake her things his way ( her wings), has stated that he falls in love at least six times a day and is shown dating two dogs at once.
- Mentor Mascot: He's responsible for helping train Jake and will often take the reins when Lao-Shi isn't around. He also has to pretend to be Lao-Shi's pet.
- Non-Human Sidekick: Notably the consistent non-human on the heroes' side given all the dragons can switch back and forth, Trixie and Spud and later Rose are normal humans and most magical creatures are just walk-ins for any given episode.
- Plucky Comic Relief: Rarely lets anything get him down or stop him from making a joke. He's also prone to cheering up Jake when the poor kid's down.
- Pungeon Master: Loves puns.
- Really 700 Years Old: He's 600 years old.
- Shipper on Deck: He is usually the one who supports Jake/Rose the most.
- Talking Animal: Has fully human speech capabilities.
Arthur P. "Spud" Spudinski
Voiced by: Charlie FinnOne of Jake's two best friends. Despite being a bit of a ditz, he's quite reliable. Season 2 shows off he is actually very intelligent, but because of how he was raised, he doesn't like to show it.
- Aborted Declaration of Love: In "Homecoming", he tried to confess to Trixie. However, Trixie cut him off and asked if they were nothing than Just Friends. He agreed wholeheartedly.
- All Guys Want Cheerleaders: In season 2, Spud's crush in on head cheerleader, Stacey.
- Cloud Cuckoolander: "Supernatural Tuesday" even gives us a peak into his mind.Spud: No matter where you go, if you try to hide, the moon will always find you.
- A Day in the Limelight: "A Befuddled Mind" and "Shaggy Frog". Also, both he and Trixie share the spotlight in "Keeping Shop".
- Evil Laugh: Has a "talent" for lampshading these. He has one as well. It needs work.
- Hidden Depths: It's been hinted several times that Spud actually has a magical background (namely that his great-grandfather may have been a wizard), but is just unaware of it.
- Not to mention the reveal he is actually something of a genius.
- I Just Want to Be Special: "Shaggy Frog" shows him being somewhat jealous of Jake for being a magical hero.
- Muggle Best Friend: He and Trixie are Jake's closest friends.
- My God, What Have I Done?: He and Trixie have this moment in "Professor Rotwood's Thesis", when they discover that Jake is the dragon they just sold to Rotwood for a cash reward.
- Mysterious Middle Initial: We never find out what the "P" stands for.
- Obfuscating Stupidity: While strange, he's not actually dumb.
- Only Known by Their Nickname: Everyone calls him Spud. The only one who calls him Arthur is his mother.
- Secret Keeper: Becomes this after learning of Jake being a dragon "Professor Rotwood's Thesis", when Jake refuses to have his memory wiped.
- Ship Tease: With Trixie. To both's happiness, they don't get romantically together.
- Stalker With a Crush: Toward Stacy. While he doesn't actually stalk her, he has invented a device made to track her anywhere on the planet.
- Superpowers For A Day: In "Shaggy Frog", a frog biting him gives him frog-like superpowers. He's cured by the end of the episode.
- Unwilling Suspension: Happens to him in "A Befuddled Mind".
- Why Did It Have to Be Snakes?: In "Half-Baked", it's revealed that he is terrified of clowns due to an incident involving a Clowny McHonk-Honk parade balloon when he was 5.Spud: Me, 12 trombonists, and the Cable Access weather lady haven't been the same since.
Voiced by: Miss KittieOne of Jake's best friends. She sometimes acts as the voice of reason. Shows signs of becoming a doctor.
- A Day in the Limelight: "Bring It On". She and Spud also share the spotlight in "Keeping Shop".
- Jerk with a Heart of Gold: She can be very rude and inconsiderate, but is a loyal and brave person.
- Military Brat: Her father is in the military and he is a fighter pilot.
- Muggle Best Friend: She and Spud are Jake's closest friends.
- My God, What Have I Done?: She and Spud have this moment in "Professor Rotwood's Thesis", when they discover that Jake is the dragon they just sold to Rotwood for a cash reward.
- One of the Boys: The only ones she hangs out with are Jake and Spud.
- Secret Keeper: She keeps Jake's magical background and duties a secret.
- She's Got Legs: An episode has Trixie becomes a cheerleader. When her friends see her in a revealing miniskirt for the first time this is their reaction. One of them goes on to talk about her legs for a while afterward, questioning why she never showed off her legs before.
- Ship Tease: With Spud. To both's happiness, they don't get romantically together.
- Verbal Tic: She uses the word "baby" a lot.
Voiced by: Mae WhitmanA hot, popular girl at school, Rose catches the attention of Jake immediately. However, there is more to this girl than meets the eye. She is actually a highly skilled hunter, trained by the Huntsclan to fight and slay dragons. Jake's girlfriend.
- Action Girl: Girl has serious skills. If the scene where she curbstomps the Huntsclan members who confront her on the Huntsman's orders in "Homecoming" and her alone giving the Dark Dragon a run for his money in "Hong Kong Longs" are any indication, she may even be a borderline One-Man Army.
- Act of True Love: Proves once and for all how much she loves Jake when she sacrifices herself to make sure he and his family are forever safe from the Huntsclan at the end of "Homecoming".
- Anti-Hero: Committing an act of genocide to save the Magical World and her family cements her as this. She's probably a Pragmatic Hero.
- Anti-Villain: Played with throughout the series. In season one, she's generally portrayed as a straight villain in her Huntsgirl persona, with it being through knowing her as Rose that makes Jake think there's good in her. It's not until season two, after her Heel–Face Turn, that the show gives her the tragic backstory of being kidnapped at birth to retroactively make her fit this trope. In addition, there are individual episodes in season two where she plays the role of a sympathetic antagonist: "The Love Cruise", where she tries to kill Jake because Jake shooting her with one of Cupid's love arrows has made her not herself and "Homecoming", where she betrays Jake because she's being blackmailed, only to be revealed to be Good All Along at the end.
- The Apprentice: She is literally at the "Apprentice Level" in the Huntsclan. She's skilled, but Jake is just as skilled, preventing her from ever rising in Huntsclan status.
- Badass Bookworm: Shows signs of being this, as she's seen reading when Jake opens a second portal to her location with the Krylock venom potion in "Half Baked" and when Jake and Haley see her walking across the street in "Switcheroo".Haley: She's pretty. Graceful. Reads books. I'd say she's way out of your league.
- Badass Normal: Pretty much the entire Huntsclan, really, but when a fourteen-year-old girl built like a drinking straw is fighting huge firebreathing dragons to a standstill know you don't want to get on her bad side.
- Battle Couple: With Jake. While they more often fight each other, there are still moments when they fight as a team, such as against the Aztec Guardian Serpent in the opening of "Breakout" or against the Chimera in "Dreamscape".
- Big Damn Heroes: Gets a couple moments, such as when she stuns the Huntsman from behind just as he's about to slay Jake in "Breakout" or when she accepts the Dark Dragon's challenge of a fighter who can take him in "Hong Kong Longs".
- Birthmark of Destiny: The Mark of the Huntsclan.
- Braids of Action: Usually wears her hair in a braid when she leaps into action.
- Child Soldiers: She's only 13-14, and her whole life has been about learning how to fight, hunt, and kill magical creatures.Rose: I've been dreaming about slaying a dragon since birth.
- Combat Pragmatist: She's not afraid to fight dirty, going for her enemy's back more than once. Case in point, she's first introduced kicking Jake from behind while he's smack-talking the Huntsman.
- Covert Pervert: "Shapeshifter" paints her this way, in her lust for pop star Jaren MacArthur. When she fights Jake while he's assumed the pop star's image with his shapeshifting powers, she goes so far as to slap his ass.
- Custom Uniform: Her season one Huntsclan uniform. In contrast, season two averts this, giving her a standard apprentice uniform.
- Death Is the Only Option: In "Homecoming", after using the Aztec Skulls to destroy the Huntsclan, her dialogue makes it clear that she genuinely believes that the deaths of her, the Huntsman, and all other Huntsclan members is the only way everyone she cares about will be safe.
- The Dog Bites Back: Considering all he did to her, it seems only fitting that, in the end, she's the one who gets to take out The Huntsman.
- The Dragon: To The Huntsman, before her Heel–Face Turn.
- Earn Your Happy Ending: At the end of "Homecoming", Jake grants her wish of a normal life.
- Genocide from the Inside: Uses the Aztec Skulls to almost entirely wipe out the Huntsclan, while being a member herself.
- Heel–Face Turn: Learning that Jake is the American Dragon is enough to show her that what she was taught about magical creatures was wrong, prompting her to do this.
- Heroic Sacrifice: Subverted. She wishes for the destruction of the Huntsclan with the Aztec Skulls, but as she soars into the air, Jake uses his wish to save her. Granted, she still gets an Obi-Wan Moment where she smiles down at Jake.
- He's Back: Female version. While there wasn't any Heroic B.S.O.D., she makes a grand return to action in "Hong Kong Longs" after she regains her memory.
- Identity Amnesia: She loses her memories of Jake and her life in the Huntsclan as a result of Jake saving her with his wish. She got better in the Grand Finale with her memories restored, though.
- I Just Want to Be Normal: She wishes she had a normal life, free of the Huntscan. Jake grants this wish.
- Killer Rabbit: That pretty girl in the picture there is capable of knocking out several mythical creatures with her Waif-Fu. Acknowledged in-universe and by the rest of the Huntsclan: when he learns of her Heel–Face Turn, the Huntsman confronts her armed and backed by four other Huntsclan members who has already slayed a dragon (a big accomplishment, they have often remarked, and a sign of their strength and skill). It takes Rose FIVE SECONDS to defeat the four Huntsclan members and hold the Huntsman at the point of his own energy lance.
- Maybe Ever After: With Jake, thanks to the show being canceled while the two of them are living in different countries.
- McNinja: Or, as Trixie calls her, "Little-Miss-Ninja-Thang".
- Only One Name: She was never given a last name. Justified by her being in the Huntsclan; her last name was originally supposed to be "Killdragonosa", but the writers chose to drop it because they figured it would have been merely a fake name given to her by the clan.
- Parental Abandonment: Rose thinks that both of her parents are dead. Turns out The Huntsman kidnapped her at birth.
- Put on a Bus: As a result of Executive Meddling after she lost her memory as a result of being rescued from an attempted Heroic Sacrifice. She was brought back in the series finale.
- Reassigned to Antarctica: At the end of season one, for "failing" to kill Jake during the Grand Equinox Hunt, she's sent back to the Huntsclan Academy to help teachers give dragon slaying lectures to trainees.
- Redemption Earns Life: Jake's wish that saves her allows her to relive her life as a normal girl.
- Reformed, but Not Tamed: If episodes like "Homecoming" and "Hong Kong Longs" are anything to go by. Yes, she's totally cool with magical creatures now, but she'll always be a trained killer. In fact, she's perfectly fine with committing mass-murder if that's what she has to do to protect those she cares about. Jake himself acknowledges this, as when he tracks down Rose in Hong Kong, he specifically tells her to kill the Dark Dragon.
- Reptiles Are Abhorrent: This is what The Huntsman taught her. She no longer believes this.
- Ret Gone: Jake's wish at the end of "Homecoming" ends up doing this to Huntsgirl.
- Roofhopping: As seen in "Old School Training", she has this ability.
- Secret Identity: Huntsgirl.
- Single Woman Seeks Good Man: Rose develops an attraction to Jake when he comforts her after Brad dumps her on their date. The attraction gets stronger as they start dating each other.
- Star-Crossed Lovers: With Jake. Even by the end of the series, despite Rose remembering Jake and last being seen having a nice moment with him, there are still obstacles making it difficult for them to truly have their happily ever after.
- Strong Family Resemblance: From what we see in "Dreamscape", "Homecoming", and "Hong Kong Longs", she's the spitting image of her mother.
- Terms of Endangerment: In season one, she has a tendency to refer to Jake as "dragon boy". After learning that Jake is the American Dragon and undergoing her Heel–Face Turn, she stops doing this.
- The Tragic Rose: Is kidnapped at birth, brainwashed, and is ultimately forced into a position where she sees sacrificing herself as the only solution.
- Tykebomb: The Huntsman raised and trained her from a young age to slay magical creatures.
- Ungrateful Bitch: At the end of "Ski Trip", after Jake saves her from falling to her death.
- Villainous Vow: Makes one in "The Hunted", before the Grand Equinox Hunt. She breaks the vow by the end of the episode.Rose: Tomorrow, I swear on our ancestors that I will slay the American Dragon and fulfill my destiny!
- Wistful Amnesia: The end of "Homecoming" implies that traces of her Huntsclan life still exist in her memory, with her asking Jake if she knows him because he looks familiar. Sure enough, in "Hong Kong Longs", she regains her memory by seeing the photo of her and Jake from the school dance at the beginning of the series and joins in on the final battle almost like nothing ever happened.
- Writing Around Trademarks: Her Huntsclan moniker had to be changed from "Thorn" to "Huntsgirl" in order to avoid legal trouble.
Voiced by: Amy BrucknerJake's younger sister who's a perfectionist and almost never gets in trouble. She has just mastered her dragon form and has just started her training.
- Always Someone Better: Subverted. While she is a better student and is shown to have natural talent with her Dragon Skills, it's also shown that this is specifically because she doesn't have to Wake Up, Go to School, Save the World like Jake does on a daily basis. After Jake temporarily gave up his role as the American Dragon, Haley had to assume the responsibility...and cracked under the pressure in less than a week. This helps her gain a new-found respect for her older brother and leads her to calling out their grandfather in "Being Human."
- In "Family Business", Haley ended up kidnapped when her dragon powers were on the fritz, courtesy of a jealous Jake, necessitating a rescue from her brother; after the rescue, Haley reveals that the powder he had pranked her with wore off pretty much right as she was getting kidnapped. It was her own fear that prevented her from fighting back. This is notably one area where Jake trumps Haley as when he was in a similar situation, he was able to get out with minimal help.
- Annoying Younger Sibling: To Jake, primarily because she's so perfect.
- Attention Whore: Seems to have shades of this, such as in "Fu and Tell." Jake later brings up how much she likes attention in "Switcheroo."
- Brother–Sister Team: Occasionally. At other times, Jake and Haley are at each other's throats.
- But Not Too Foreign: Like her brother, she's half Chinese and half Caucasian.
- Calling the Old Man Out: Does this to her grandfather in "Being Human."
- Child Prodigy: Season two shows her to have natural dragon talent, showing her brother up like she always does. It's also established that she attends a school for gifted children.
- Distressed Damsel: At the end of "Family Business".
- Half-Human Hybrid: Just like her big brother.
- Meaningful Name: Haley is named after Haley's Comet; Susan Long took a liking to the name after she and Jonathan attended a party and watched the comet bypass Earth in orbit.
- Pint-Sized Kid: It's established in "The Legend of the Dragon Tooth" and "Switcheroo" that she is literally only 2 feet tall.
- Tertiary Sexual Characteristics: Her dragon form is pink.
- Wake Up, Go to School, Save the World: Deconstructed in "Being Human," where she temporarily takes over as the American Dragon...and is reduced to a nervous wreck in less than a week. She does gain a newfound respect for her brother and defends against their grandfather, pointing out the severity the job takes one as well as mentioning the personal losses Jake went through as a result.
- Badass Normal: Has no magical powers, yet can hold his own against the Jersey Devil (and even better—he thought it was a bear, meaning that he was willing to go after a bear to save his son).
- Crouching Moron, Hidden Badass:
- When the Jersey's Devil attacked him, he mistook it for a bear and went into survival mode. When the Jersey's Devil attacked Jake, he still mistook it for a bear and threw it down off a cliff with a Swiss Army Weapon fitted with bear spray.
- He defeated the entire army of Shade Demons in the series finale by grabbing a ceremonial vase with his fanny pack and reflected moonlight off of it. Jake even lampshades it proudly.
- Papa Wolf: See the first example of his Crouching Moron, Hidden Badass entry. Also when Jake was defeated by some vampires (they were masquerading as important business associates), Jonathan got pissed and let them have it.
- Secret Keeper: In the series finale, "Hong Kong Longs", he finds out about his wife's side of the family being dragons and the existence of magical creatures. But rather than leave Susan or get angry, he's very accepting of it, and admits that he always had a feeling that there was something "magical" about his family.
- Supernatural-Proof Father: However, according to one of the writers of the show on the Toonzone forums, at one point there were plans to reveal that he's a werewolf, essentially making Jake and Haley Heinz Hybrids.
Voiced by: Lauren TomJake's mother. She has no magical powers, since they skipped her generation. She is reluctant to reveal her family's heritage to her husband (apparently out of the fear that he will abandon her), and to this end, lies to her husband about Jake's business, sometimes letting Jake take the fall.
Voiced by: Sandra OhThe Korean Dragon, Haley's dragon master and Jake's Home Economics teacher.
- First-Name Basis: "Please, call me Sun. Miss Park is so formal."
- Hippie Teacher: She doesn't like being called "Ms. Park", says words like "groovy" and believes that violence is for the weak and cowardly.
- Like a Son to Me: While she never outright says it, it's clear as day that she cares for Haley as if she were her own daughter.
- Mysterious Watcher: She seems to come off as this towards Jake in her first appearance, before she turns out to be Haley's mentor.
- Sensei-chan: To the point that she very rarely gives out letter grades.
- Technical Pacifist: This exchange during one of her fights:Chang: Sun Park, I thought you were all about peace and love.Sun: And what I really love is to give you a piece of this!
- The Worf Effect: Appears to be a victim of this. She is easily defeated by Chang (twice), is blasted out of the air by The Dark Dragon in the series finale and even gets attacked by humans with soda cans in "Haley Gone Wild".
- Worf Had the Flu: A pacifist dragon against humans means a lot of holding back. Also justified with the Dark Dragon and Chang; Chang is quite more experienced and violent than she, and the Dark Dragon in the Grand Finale is so powerful that when he blasted her he was also taking on and winning against dozens of dragons at once, including the only two who had actually managed to defeat him in the past.
The Huntsman (Huntsmaster)
- Arch-Enemy: To Jake. As season two progresses, he also becomes this to Rose.
- Badass Cape: As leader of the Huntsclan, he wears one of these.
- Bald of Evil: It's revealed in his final appearance that he's actually bald.
- Big Bad: The show's main villain, who's closely tied to the Jake/Rose Myth Arc. Most noticeable in season two, where his master plan of using the Aztec Skulls to destroy all magical creatures serves as the primary overarching threat and Story Arc.
- Birthmark of Destiny: And a big one he has. Though it was smaller in season one.
- Blackmail Backfire: Him blackmailing Rose in "Homecoming" leads directly to his death by her hands at the end of the episode.
- Butt-Monkey: He was seen as this by his peers and the time-traveling Jake when he was a teenager. That was before his voice changed and he became the man he was in the series; the kind of man whose intensity and hatred made his tormentors cower in fear.
- Cool Helmet: It's a dragon skull.
- Darth Vader Clone: He's got the deep voice, cape, dark outfit, weapon, and helmet. There's even a scene in "Act 4, Scene 15" where his helmet is lowered down onto his deformed head, in a clear homage to The Empire Strikes Back.
- Deader Than Dead: Killed with an irreversible wish that completely wipes him from the face of the earth. Really driven home by how, after Jake wishes that Rose was never kidnapped at birth by the Huntsclan—which should mean that Rose was never there to wish for the destruction of the Huntsclan—he's still gone.
- Death by Secret Identity: Discovers Jake's human form when he arrives at the location where the Aztec Skulls must be activated, and Jake is there to confront him. He doesn't survive the encounter.
- Disc-One Final Boss: Downplayed. There are still 13 episodes left in the show after Rose kills him, but these episodes lack an overarching plot and villain, with the Dark Dragon himself only taking center stage in the finale, leaving the Huntsman's status as the Big Bad of the show secure.
- Dramatic Unmask: Averted. He's unmasked in his final battle with Jake, only to reveal...a completely unfamiliar, bald man with a nasty facial scar.
- Evil Cannot Comprehend Good: The only reason he fails in the end is that he turns his back on a known traitor, viewing her as blackmailed into submission rather than motivated to sacrifice her own life to keep all magical creatures as well as her family safe.
- Evil Laugh: Has one every now and then. He's the only major villain with one who never gets it lampshaded by Spud.
- Evil Sounds Deep: Speaks with a deep, growling voice.
- The Faceless: He wears the skull of the first dragon he ever killed upon his head. His face is only shown after Jake slams him into an elevator door, shattering the helmet.
- Fantastic Racism: He hates all magical creatures, to the point where his master plan in season two was to have them all wiped out of existence.
- Faux Affably Evil: Has his moments when he seems to get a kick out of feigning politeness to mock his enemies, such as when he speaks to the captured Andam, Kulde, and Chang like they're honored guests in "The Halloween Bash" or when he bows to Rose and thanks her for coming to see him when she's so busy with her social life before he reveals that he knows she's a traitor in "Homecoming".
- From Nobody to Nightmare: An episode in Season 2 reveals that he was a rather wimpy member of the Huntsclan who was bullied by people more skilled than him. He's since become the #4 threat to all magical beings.
- Hoist by His Own Petard: Attempts to wish all magical creatures out of existence, only to have his wish turned against him by his protege.
- Hunting the Most Dangerous Game: The Huntsclan's annual Grand Equinox Hunt.
- Implied Death Threat: He does this twice in season two.
The Huntsman: I assure you, they're quite safe, and they'll remain that way as long as you do exactly as I say and bring me those skulls. Tonight.
- This being a Disney show, this is how the writers got away with him threatening Rose's family in "Homecoming".
The Huntsman: Then I shall take your refusal as an admission of treason. You of all people know the consequence of betraying the Huntsclan.
- He even does this to Rose herself in "Breakout", when she suggests she's going to refuse bringing him the pelt of the dragon she "killed".
- In the Back: Rose blasts him from behind with her staff. Twice. The first time, in "Breakout", only knocks him out. The second time, in "Homecoming", he doesn't recover from.
- Karmic Death: Killed by his own protege, who uses a wish he planned to use to wipe him from existence forever.
- Kick the Dog: His entire relationship with Rose is founded on him emotionally abusing her. In particular, him telling Rose to not come home if she doesn't have an abominable snowman pelt in "Ski Trip" seems to be there for no other reason to make the Huntsman look like a dick and make us feel bad for Rose.
- Killed Mid-Sentence: Rose lets him start his wish, but she makes sure he doesn't get to finish it.
- A Nazi by Any Other Name: Wants little more than the destruction of all magical creatures.
- No Body Left Behind: When the Aztec Skulls get through with him, his cape is all that's left.
- No Name Given: He's just called "The Huntsman", or "Huntsmaster" by his followers.
- Properly Paranoid: He's either that or Crazy-Prepared, given he kept track of Rose's parents for fourteen years in the off-chance she rejected her Huntsclan upbringing and he needed to blackmail her into doing his bidding.
- Red Eyes, Take Warning: In Season One, his eyes were glowing red pinpricks under his mask. Season two goes with more humanlike eyes, which actually ups the scare factor with him as it shows that he's human.
- Smug Snake: If he thinks that things are going his way, he can be very, very smug. "The Halloween Bash" is a perfect example.
- Stranger Behind the Mask: He's never shown without his mask, until his final appearance where the helmet breaks. When we finally do get to see who he really is, it turns out he's a total stranger.
- Super Strength: He possibly has this. He is shown punching through a brick wall, is barely fazed by being slammed head-first through an elevator door, and he then rips one of the pulleys from the shaft and slams it onto the ground in a fit of rage.
- Top-Heavy Guy: In his season two design, his upper half is noticeably much more muscular than his lower half.
- Vile Villain, Saccharine Show: He's a genocidal, child abducting and brainwashing maniac who wears the skull of the first dragon he ever killed as a trophy. In a Disney cartoon. And yes, whenever he shows up, the stakes rise and the tone of the show becomes more serious.
- Villain Ball: Y'know Huntsman, if you had just executed Rose after she gave you the last Aztec Skull and defeated Jake, she never would have had the chance to shoot you from behind and wish for your death.
- Villainous Vow: The end of "Hero of the Hourglass" reveals that he made one as a teenager.The Huntsman: Dragons! I will slay each and every one of them, if it takes until the end of time!
- Would Hurt a Child: There's the fact that, under his leadership, the Huntsclan Academy punishes its students by forcing them to fight a kraken, for one. Also, when he was about to use the Aztec Skulls to kill all magical creatures in "Homecoming", one of the dragons present and being restrained was an 8 year old girl.
The Dark Dragon
Voiced by: Clancy BrownThe #1 threat to the Magical World and apparently the only dragon to ever go bad, The Dark Dragon hates all humans and wishes to overthrow the human race, not to mention to convert all of the world's dragons to his side.
- Arch-Enemy: As the #1 threat of the Magical World, he could be seen as this to all magical creatures. On a more personal level, he's this for Lao-Shi, as Lao-Shi defeated him in the past.
- Back from the Dead: At the end of "Being Human", thanks to a drop of Jake's blood.
- Breath Weapon: Like all dragons, he breathes fire.
- Defeating the Undefeatable: Before Lao Shi, nobody survived a fight with him. Then young Lao Shi defeated and apparently drowned him. Then in season 1, Jake (who had barely escaped him in their first encounter) masterminds his defeat and first death, and in the series finale, when he had been empowered to the point that dozens of dragons were no match for him, Rose put him down for good.
- Evil Laugh: Spud won't shut up about how cliched his laugh is in "Hong Kong Longs".
- Evil Sounds Deep: Courtesy of of Clancy Brown.
- Fate Worse Than Death: Trapped inside a temple for 1,000 years.
- Fantastic Racism: Sort of the opposite of the Huntsman, as he sees humans as inferior.
- Final Boss: Ends up being this of the series.
- Greater-Scope Villain: The #1 threat to the Magical World has a speaking role in all of three episodes.
- Large Ham: "You have no idea of my DARK POWERS!"
- Misanthrope Supreme: Has intense hatred for humans.
- No Name Given: He's just "The Dark Dragon".
- One-Man Army: In "Hong Kong Longs", he singlehandedly curbstomps all the dragons of the world.
- Palette Swap: In Season 1, his appearance is similar to that of Jake's Dragon form, with a similar jawline, body pattern, and hairstyle, only black and purple. Season 2 gives him a much more distinct appearance along with being black and blue.
- Shock and Awe: He is shown shooting lightning from his fingers in "Hong Kong Longs".
- Super Strength: He is a dragon, after all.
- Taking You with Me: He tries to do this to Jake and Rose at the end of "Hong Kong Longs" as he's about to become trapped in the temple.
- Tempting Fate: In the series finale, upon defeating all of the world's dragons, he asks if there is anyone who could challenge him. Rose heard him and was willing to accept the challenge.
- Red Eyes, Take Warning: In his season two design.
- We Can Rule Together: Wants to create an army of magical creatures to aid him in taking back the world from humans.The Dark Dragon: Greetings my dragon brothers and sisters! Allow me to propose another toast: to dragons ruling the world!
Voiced by: Lauren TomA member of the Dragon Council; a dragon from Asia. Chang is harsh and cold when it comes to Jake. Unsurprisingly, she turns out to be a mole for The Dark Dragon, secretly aiding him in his plot to recruit Jake and overthrow the human race.
Tropes Associated With Councilor Chang:
- Art Shift: Got hit with this the most in season 2. She was originally a Miniature Senior Citizens about Jake's grandfather's height in her human form in the first season. The re-design suddenly cranked her to human height out of the blue.
- Cardboard Prison: She was sent to one after she was exposed as The Mole.
- The Dragon: Right hand woman to The Dark Dragon.
- Dragon Ascendant: Briefly, in "Nobody's Fu" and "Being Human", where she tries to get revenge for her imprisonment and resurrect the Dark Dragon, respectively. She goes back to serving the Dark Dragon in "Hong Kong Longs".
- Large Ham: "TISK, TISK Mister Long."
- Misanthrope Supreme: Shares the Dark Dragon's hatred of humans.
- The Mole: She's been working with the Dark Dragon the whole time.
- Obviously Evil: Pretty much, the fact that in her first appearance, she's heavily biased against Jake during the Dragon Competition is an obvious clue.
- Her human self's season two redesign reeks of this, wearing a black and red outfit, and having a pale purple skin tone.
- Psycho Ex-Girlfriend: To Grandpa. They dated once, but she turned out to be working with the Dark Dragon.
- Puny Humans: Her opinion on humans. Ironically in both season finale final battles it was a combination of humans and mystical creatures working together that beat both her and the Dark Dragon.
- Ungrateful Bitch: Despite Jake saving her (along with the rest of the Dragon Council) from the Huntsclan in "The Halloween Bash," she still tries to eliminate him whenever she gets the chance.
- Villain: Exit, Stage Left!: Well, more like fall offstage, but it's obvious that her exit in "Hong Kong Longs" was meant to serve as both a defeat and to keep her for a third season (which never happened) where she possibly could have been the Big Bad.
- Villain Has a Point: She's actually right about humans subjugating magical creatures, which is something even Jake points out in "The Halloween Bash" in regards to his party bringing humans and magical creatures together. It's just, you know, wanting to enslave humanity and kill any dragon who stands in your way isn't the best way to deal with the situation.
- Well-Intentioned Extremist: Her reason for joining the Dark Dragon is because she's tired of magical creatures being subjugated by humans.Jake: So, everyone knows that the Dark Dragon is one twisted dude, but what about you, Chang? I thought you cared about magical creatures.Chang: I do. Magical creatures once ruled the earth, until humans forced us into hiding.
Voiced by: Adam WylieThe first ever "Hip Hop Helper Monkey", Bananas B takes over as Jake's Animal Guardian after Fu's license expires.
- Dirty Coward: What leads to him doing a Face–Heel Turn.
- The Dragon: He becomes this when Chang agrees to let him team up with her.
Professor Hans Rotwood
Voiced by: Paul RuggA teacher at Jake's school, Rotwood believes in the Magical World (although his facts about magical creatures are inaccurate). His beliefs got him discredited as a scientist, and he now works as the principal of Jake's school. He has a strong dislike of Jake, namely for Jake's bad attitude.
- Butt-Monkey: In "Ski Trip".
- Enemy Mine: He and Jake make an alliance in "The Rotwood Files" to get Sigmund Brock fired. Later, they're forced to work together in "Magic Enemy #1".
- Evil Teacher: Played straight and subverted. In many episodes, it seems that his only purpose is to make Jake miserable and he wants to expose the Magical World to humans, but it is shown that he is not a true threat and even has a true respect for the Magical World.
- Manipulative Bastard: Sometimes, especially at the end of "The Rotwood Files".
- Not-So-Harmless Villain: He's normally a Butt-Monkey. Then we get "The Rotwood Files"...
- They Call Me Mister Tibbs: He prefers to be called "Professor".
Huntsboys #88 and #89
Huntsboy #88 Voiced by: Kyle MasseyTwo young Huntsclan students who are able to lie themselves up to apprentice level in the Huntsclan.
Huntsboy #89 Voiced by: Nicholas Brendon
Huntsboy #89 Voiced by: Nicholas Brendon
- Co-Dragons: With Rose having performed a Heel–Face Turn, they serve as this for The Huntsman in season two.
- Dragon Ascendant: With the rest of the Huntsclan—save Rose—dead, "Shaggy Frog" shows them taking up all the technology of the Huntsclan for themselves.
- Infant Immortality: They manage to survive the destruction of the Huntsclan, but only by resigning before the effect could reach them.
- Miles Gloriosus: They both play themselves up as being fearless dragon-slayers, but usually run away when confronted by Jake or some other magical beast.
- Not-So-Harmless Villain: "Shaggy Frog" shows that, while still comedic, they are capable of actually being threats. Even before then, they catch on to Rose's odd behaviors while she secretly tries to help Jake.
- Screw This, I'm Outta Here!: What they always do when things don't go according to plan.
- Those Two Bad Guys: The Huntsman's two new apprentices.
- Took a Level in Badass: "Shaggy Frog" shows them as actually capable Huntsclan members.
- You Are Number 6: They're only ever referred to by the numbers the Huntsclan Academy assigned them, even after they become apprentices.
- Vile Villain, Laughable Lackey: While they are happily complicit with all of the Huntsclan's crimes, they are nonetheless more cowardly and less competent, serving as comic relief enemies that even Jake, Rose, and the others don't take very seriously.
- Villains Out Shopping: In the Christmas Episode.
Voiced by: Jonathan FreemanThe Wizard of Wall Street, Pandarus desires to become the most powerful wizard in the Magical World.
- Card-Carrying Villain: Appears to be one in "A Befuddled Mind"Jake: Eli Pandarus! What's a lying, cheating, evil wizard doing in a place like this?Pandarus: You say the sweetest things.
- Evil Laugh: Gets lampshaded by Spud in "A Befuddled Mind".
- Evil Sorcerer: He's called "The Wizard of Wall Street" for this reason. Humorously, he shares a voice actor with another evil sorcerer Disney created.
- Took a Level in Badass: Is much more ruthless and capable in his appearance in season two, in contrast to season one, where he cowers when beaten.
Fury, Euryale and Medusa (The Gorgon Sisters)
Voiced by: Hynden WalchThree ancient sisters who, when together, can combine their powers to turn their enemies to stone. When separated, they can only hypnotize their enemies.
- Gorgeous Gorgon: Lampshaded by Fury, who says "Wow, I am hot" when looking at herself in a mirror.
- Sadly Mythtaken: Their backstory notwithstanding, Fury was known as "Stheno" in the original myths (but then again, how many people can pronounce that?). Additionally, reflective surfaces could not deflect the Gorgons' Brown Note.
- Smug Snake: Figuratively and literally! Their mutual desire to be the best leads to their downfall and they have a snake motif.
- Taken for Granite: On both the giving and receiving end of this trope. They're defeated first when their magic is turned on them and then when they turn it on each other.
- Villain: Exit, Stage Left!: Fury at the end of "Furious Jealousy". It really seems like the writers were trying to keep as many options open as possible when it came to villains in the third season (which never happened).
- Why Did It Have to Be Snakes?: Fury gets this reaction from Jake when her hair attacks him.
- Wolverine Publicity: Lampshaded by Trixie when she pulls a Batman Gambit on the three of them to try and get them to turn each other to stone—Trixie claims that Medusa should be the leader of the three since everyone knows who she is, while it's unlikely that anyone has ever actually heard of either of her sisters.
Voiced by: Corey BurtonRotwood's old professor who takes his job as principal of Jake's school after Rotwood gets fired. Needless to say, he's more of a threat than Rotwood. He invented a chemical that can expose dragons while they're in their human form thanks to funding from what is implied to be the Huntsclan.
- Bitch in Sheep's Clothing: Male version. "Hola students! My name is Sigmund Brock and this school year is going to ROCK!" It all goes downhill from there for Jake.
- Hair-Trigger Temper: According to Rotwood, when he was his mentor, he "exploded with rage at the slightest mistake".
- Outgambitted: At the end of "The Rotwood Files" he's tricked into showing Jake and friends in a cage and trying to expose Spud as a dragon. All courtesy of Rotwood, who proceeds to take back his job and steal the last drop of the dragon-revealing liquid to make sure Jake is a dragon.
- Sadist Teacher: After Jake tries to get him fired, Brock gets revenge by taking advantage of his popularity at the school and going over the intercom and tells the entire school that "Jake Long in Homeroom 217, Locker 8331" was behind it, effectively leaving Jake at the mercy of a very angry student body.
- Villain with Good Publicity: To the students, he's a very respectable professor. To Jake however, he's a threat.
Yang (Evil) Jake
Voiced by: Dante BascoAn evil doppelganger that Jake accidentally makes of himself with a negative dragon chi amplifier. Yang Jake's goal is to absorb all of Jake's other doppelgangers so he can overpower and absorb Jake, becoming Jake Long himself.
- The Assimilator: Absorbs Jake's other doppelgangers for power.
- Doppelgänger: One made from dark chi energy.
- Evil Sounds Deep: Dante Basco uses a slightly, but still noticeably deeper voice for Yang Jake than he does for the real Jake.
- Fireball Eyeballs: The first sign that he's evil is when his eyes start flashing fire.
- Kill and Replace: Wants to absorb Jake and become him.
- Pun: Makes one every single time he absorbs a doppelganger.Yang Jake: Too bad for you I'm so self absorbed!
Voiced by: John C. McGinleyA dentist working for the Tooth Fairy that betrays her and steals her wand, planning on stealing Haley's loose dragon tooth so he can claim its power.
- One-Winged Angel: Haley's dragon tooth causes him to become a monster made out of teeth.
- Only in It for the Money: He views The Tooth Fairy's job as a business and wants the power of Haley's tooth so he can get back every cent she gave away.
- Killed Off for Real: All that's left of him after his defeat are his glasses.
- Meaningful Name: Diente means "tooth" in Spanish.
Yan-Yan (Miss Tinkles)
Voiced by: Tia CarrereA Chinese Hairless cat and Fu Dog's ancient rival. For centuries, she and Fu Dog have been fighting over Fu's family coin. She is currently posing as Olivia Mears' pet.
- Arch-Enemy: Fu's ancient rival. According to "Fu and Tell", she and Fu Dog have a history of fighting over Fu's coin.
- Atrocious Alias: "Miss Tinkles".
Voiced by: Clarence Williams IIIThe Dragon of Africa and one of the members of the world's Dragon Council.
- Distressed Dude: In "The Halloween Bash", he's captured by the Huntsclan and almost slain.
- Foil: Arguably, to Chang. Unlike her, he shows a genuine supportive side towards Jake, and sees a lot of potential in him. And while he may respect the rules as much as she does, he's not afraid to bend them once in a while for those who've earned it.
- An Ice Person: Unlike most in the dragons in this series that breathe fire, Councilor Kulde is an ice dragon.
- Minor Major Character: As a member of the Dragon Council, he's essentially one of the leaders of the Magical World, but he only appears in about 4 episodes
Sara and Kara (The Oracle Twins)
- Black Comedy: Sara is a source of this. The very first thing she does when she meets Jake is to cheerily ask him if he wants to know when he's going to die.
- Blessed with Suck: In "Bodyguard Duty", it's implied that Kara feels this way about her powers.Kara: When you only see good things, nothing's special anymore. All the pleasant surprises are taken out of life.
- Cursed with Awesome: "Bodyguard Duty", implies that Sara feels this way about her powers.Sara: But, when you only see bad stuff, even the smallest bit of good news makes you happy!
- Goth: Kara in season two.
- Identical Twin ID Tag: Played straight, then averted. In the first season they just dressed differently, although in Season 2, they are given drastically different designs.
- Polar Opposite Twins: Kara is moody and antisocial, while Sara is constantly cheerful.
- Prophecies Are Always Right: Their visions always come true except for when Disney Channel Executives tell them that one of their visions is going to be false.
- Prophecy Twist: While their Prophecies Are Always Right, some of them aren't as expected.
- Oracle: Both of them; Kara can only predict good events, while Sara can only predict bad ones.
- Tomboy and Girly Girl: Kara and Sara, respectively.
Voiced by: Adam WylieA young wizard hailing from the United Kingdom who is the newest transfer student to Jake's school; Nigel has come to New York to complete his training, taking advantage of the magical background of the city.
- Fire-Forged Friends: He was a rival to Jake in skateboarding and rapping, but after they stopped an ogre from reclaiming his mind-reading helmet, they ended up becoming friends with a healthy rivalry.
Voiced by: Adam WylieThe Australian Dragon. According to Fu Dog, he was the "new kid" until Jake came along. He and Jake engage in a battle of pranks with one another in the episode "Dragon Summit".
- James Bondage: At the end of the episode.
- Jerk Ass: Let's see, he's the one who started everything in the episode by tripping Jake and getting him in trouble with the Dragon Council and then knocks a squirrel's nut away.
- Jerk with a Heart of Gold: He does come back to help Jake escape from the Dark Dragon and thanks him for his help.
Voiced by: Kari WahlgrenAn intelligent mermaid who has a fear of water. Jake befriends her during the Grand Equinox Hunt.
- Ironic Fear: Of water.
Voiced by: Edie McClurgA dimwitted giantess that Jake befriends during the Grand Equinox Hunt.
An unlucky leprechaun that Jake befriends during the Grand Equinox Hunt.
A brownie that Jake befriends during the Grand Equinox Hunt. Do not set off his temper.
Voiced by: Susanne BlakesleeThe paraplegic first principal of Jake's school. In "Something Fishy This Way Comes", she starts dating Jake's grandfather. Oh, and she's a mermaid.
- Obfuscating Disability: She was in a wheelchair for all of her appearances. Turns out, it's because she's a mermaid.
- Red Herring: Jake thinks she's the Kelpie for a while. Turns out she's actually a mermaid police officer.
- The Reveal: She's not the Kelpie...But she thought Jake was when he was having trouble in school.
- Chuck Cunningham Syndrome: She was a recurring character in season 1 but kind of vanished after season 2.
Voiced by: Ron MasakThe current Grim Reaper and Fu Dog's old buddy. Just because he'll one day claim your soul doesn't mean he isn't a pretty cool dude.
- Don't Fear the Reaper: Is a generally pleasant guy; Fu in particular adores him.
- The Grim Reaper: Duh. He didn't always hold the title though, and thus typically had a bunch of dead-end jobs (pun intended) before he got this one.
- The Prankster: Loves to pull pranks. Fu finally manages to pull one on him by dressing up like a new Grim Reaper and implying that he's there to replace him.
- You Kill It, You Bought It: Apparently, this is the way one becomes the Grim Reaper in the first place.
Trixie's crush. Seems like the strong silent type at first but proves to be very social later on.
- But Not Too Foreign: Has a very slight Hispanic accent.
- Chick Magnet: A number of girls (aside from Trixie) have found him attractive.
- Hidden Depths: He isn't as secretive as he seems, and is shown to be a good guy.
- Nice Guy: Optimistic by default, and very genuine.
- Younger Than They Look: He's 14, but could easily pass for 18-21.
- Corrupt Corporate Executive: A rather mild, non-villainous version. He makes a sale to The Huntsman, telling an angry Jake that it's "just business". Of course, then he finds out what was inside the box that he sold The Huntsman.
- Nice Job Breaking It, Hero!: Yes, Brocomus. Enjoy your money while The Huntsman enjoys using that Aztec Skull that you inadvertently sold him.
Aztec Guardian Serpent
This large snake guards one of the missing Aztec Skulls and has an innate ability to get the skull back if it is taken.
- Anti-Villain: Type IV. Its job is to guard an Aztec Crystal Skull, and so to it, Jake is just as much a threat as the Huntsclan is.
- Feathered Serpent: Quite possibly, it's hard to tell though due to the animation style.
- You Have Outlived Your Usefulness: Once the Huntsman gets the skull, he destroys the Guardian Serpent.
The Jersey Devil
- Disney Villain Death: Mr. Long drives it off a cliff. Possibly subverted, though, 'cause it can fly.
- All Your Powers Combined: Can feed off of a multitude of magical creatures to gain their abilities, including dragons.
- Serial Killer: Essentially, considering it's fed on plenty of magical creatures based on how often it shapeshifts and Silver's dialogue pretty much confirms that the victim dies if the Kelpie finishes feeding, although Lao-Shi himself survives the Kelpie feeding on him enough to shapeshift into him.
- Vile Villain, Saccharine Show: It's pretty much a horror movie monster, stuck in an episode about the wacky hijinks that ensue from Lao-Shi dating Principal Derceto.
- Depraved Kids' Show Host: His show hypnotizes small children into doing amoral acts.
- Oh, Crap!: gets one when Jake breaks Hailey out of his brainwashing AND her supremely pissed at him. Quite comprensible, given it was a Woman Scorned with super strength and fire breath...
- What Happened to the Mouse?: He was last seen when he was just about to be attacked by Haley. Haley said in the end credit scene that his show was cancelled, but we never see what she does to him.
The Krylock Demon
A magical creature that has the head of a snake and the body of a scorpion. It is very venomous, and if its venom is consumed, it will transform the eater into a Krylock Demon. The #3 threat to the magical community.
- Eldritch Abomination: It's a terrifying, venomous creature with the head of a cobra and the body of a scorpion that lives in another dimension which is only accessible via a magical potion.
- Hoist by His Own Petard: Its venom is what destroys it.
- Viral Transformation: If one consumes a Krylock's venom, they become a Krylock themselves. Oh, and Haley reveals that dragons aren't immune to this.
An ancient magical creature that sucks the life out of its victims to stay young. The #10 threat to the magical community. In the episode "Young At Heart", Jake, Trixie and Spud are its unfortunate victims.
Voiced by: Matt NolanA jock at Jake's school. He constantly torments Jake and also tries to woo Rose whenever he gets the chance.
- The Ditz: He doesn't even recognize the word "parents" in a letter written on a sticky note. No wonder why he was held back in school twice.
- Establishing Character Moment: Leaving Rose at the school dance for Jake's date.
- Held Back in School: Twice back when he was a third grader. He brings this up to explain having a driver's license in spite of being a middle schooler.
- Jerk Jock: Seriously, this guy makes Flash Thompson half-way decent in comparison.
- Kick the Dog: Abandoning Rose at the school dance for Jake's date.
He succeeds...kind of...
- Alpha Bitch: Although this seems to be played straight most of the time, this trope appears to be subverted at the end when she reveals that she was touched by Spud's attempts to win her heart.
- Give Geeks a Chance: Eventually does genuinely fall for Spud, though she insists on keeping their relationship secret to uphold her reputation. Baby steps...
- Hidden Depths: "The Rotwood Files" reveals that she has a thing for sensitive guys, something you wouldn't expect from a girl like her.
- Mugging the Monster: In her first episode, when they couldn't pass before a wall without insulting it, she and her teammates insulted Fury. They got off easy, given they were just brainwashed...
- Not Brainwashed: Spud thinks she's under some kind of spell when she briefly dates Nigel (not without justification, considering Nigel's more manipulative side). She's not, but she's also not romantically interested in Nigel.
Voiced by: Jessica Di CiccoA cute swim team captain at Jake's school. After Rose moves to Hong Kong, Jake decides that Danika is the one for him once he decides to get back into the dating game.
Cousin "Greggy" Gregory
Voiced by: Will FriedleJake's annoying younger cousin who just mastered his dragon form.
- Attention Whore: He's worse than Haley.Greggy: No way I'm letting Jake steal my glory!
- Small Name, Big Ego: Thinks that since he has JUST mastered his dragon form, he's more experienced than Jake.
- Ungrateful Bastard: Subverted. He does thank Jake after he's rescued from nearly drowning, but as soon as Jake gives him the tiniest bit of credit for helping save the day, his ego comes back full force and he then claims that he saved Jake.
Rose's unnamed mother, father and twin that she was kidnapped from at birth.
- Adult Fear: Having one of your daughters kidnapped right after her birth, with you unable to do anything to help her has got to be rough.
- Chuck Cunningham Syndrome: Rose's twin. She was never seen again after her short amount of screen time when she was a baby. Supposedly her whereabouts would've become a plot point had the show been allowed to go on for another season.
- I Have Your Wife: Sort of. The family isn't actually being held hostage, but The Huntsman knows exactly where they are. And he will have them killed if Rose does not obey.
- No Name Given: None of their names are ever revealed.
- Parental Abandonment: Not that they had any choice in the matter...
