Once upon a time, a [[InterspeciesRomance gigantic rampaging dragon and a human woman fell in love]]. The product of their union was Duncan, a HalfHumanHybrid. Though they divorced, Duncan's parents share custody. He spends most of his time trying to fit in at school despite his obviously draconic features, and when with his dad he is tutored in the ways of becoming the next king of the world's {{Kaiju}}.

For real.

Fun fact: The character was originally supposed to be a member of the ComicBook/YoungAvengers in the Franchise/MarvelUniverse and Duncan was to be the son of the alien dragon Fin Fang Foom, a foe of ComicBook/IronMan.

An animated movie based on the comic premiered November 2010, on Creator/CartoonNetwork from the creator of ''WesternAnimation/AeonFlux''.

!!This comic book series provides examples of:

* ActionGirl[=/=]ActionMom: Margaret, in the movie at least. Flies jets, shoots, threatens Belloc and means it.
* AdaptationDistillation
* AllCGICartoon: The movie adaption.
* AllOfTheOtherReindeer: Kids at school sometimes foolishly persist in picking on Duncan despite the fact that he's a fire-breathing monster and his dad is ten times worse.
* AlliterativeTitle: A school example: '''H'''erbert '''H'''oover '''H'''igh.
* ArtShift: The beginning show the movie in a traditional type of animation, before becoming CGI for the entire movie.
* BettyAndVeronica: Isabel and Jenna.
** Kenny (Betty) and Duncan (Veronica) for Isabel's Archie, however this is all one sided from Kenny's point-of-view.
%%* BigDamnHeroes
* BigNo: Duncan gives one when Barnes orders another full attack on Belloc.
* BizarreAlienBiology: Though Duncan looks mostly human, he eats coal rather than human food.
** He apparently enjoys Twinkies though. At least, we can assume so as his mother packed some in his lunch.
%%* BullyingADragon: ''Literally.''
* CallingTheOldManOut: Duncan immediately does this to his father for forcing him into something he doesn't want, even though Belloc wasn't in his life for sixteen years.
* CaptainErsatz: Duncan's father, the dragon Belloc, is initially presented as a Captain Ersatz of Godzilla, but is later developed beyond that into the more traditional, Tolkien-esque ancient dragon of intelligence and greed who [[DragonHoard hoards treasure]], then his backstory was revealed to be more in the line of Fin Fang Foom as he and the other kaiju are aliens.
* ChekhovsGunman: [[spoiler: Belloc knew he made the right choice to mate with Margaret.]]
%%* ComingOfAgeStory
* CursedWithAwesome: Orange skin and bullying aside, one can't help but wonder what Duncan finds so terrible about being inhumanly strong, impervious to extreme heat, and being able to breathe fire... and this is before he gets his true powers unlocked.
%%* DidYouJustRomanceCthulhu
* DraconicHumanoid: Guess who...
* EvilLaugh: The kaiju are very fond of this.
* {{Fingore}}: Duncan defeats one kaiju in the movie by bending its finger back 180 degrees. ''Ouch.''
* FourFingeredHands:
** Duncan plays this for laughs, asking the principal to "Help me out here. [[GettingCrapPastTheRadar Exactly which one is "the bird"?]]" and showing the five fingered principal, his four fingered hands.
** The animated movie gives him five fingers. As giving the horns is the recurring hand gesture of the movie, this is easy to notice.
%%* FreeTheFrogs
* AGlassInTheHand: Kenny manages a glass in ''each'' hand.
* GettingCrapPastTheRadar: Literally a few times. Also, "They're [[ItMakesSenseInContext waterboarding Kermit (the frog)!"]]
** Isabel flat-out calls the jocks "sphincters".
%%* GodzillaThreshold
* GoshDangitToHeck: Barnes is fond of this.
* HalfHumanHybrid: Somehow a woman became pregnant with a 60,000-pound dragon's baby. Duncan [[TooMuchInformation does not want to know how]].
* HighSchool: Where most of the story takes place.
* HighSchoolDance: The climax starts here of all places.
* HopelessSuitor: Kenny to Isabel, and Isabel to Duncan.
* HotBlooded: Duncan. Clearly gets it from his dad.
%%* HotSkittyOnWailordAction:
* HumanMomNonhumanDad: Naturally. Even provides the current page image.
%%* IJustWantToBeNormal
* IfYouKillHimYouWillBeJustLikeHim: [[spoiler:Margaret basically said this trope as a reason why Duncan didn't kill the two Kaijus. Though he wanted to but his reason not to is because "it wouldn't change anything". Meaning that the rest of Belloc's subjects ''still'' wouldn't accept Duncan as their future king.]]
* IncrediblyLamePun: "And orange you just adorable."
* InnocentlyInsensitive: Jenna gives Duncan the cold shoulder when he comments on how Troy would want his dad to just disappear. A few minutes later, Isabel informs Duncan that Jenna's father is dead.
* InterspeciesRomance: Naturally. Duncan's mom ''does'' try to explain this to him, saying "[[HotSkittyOnWailordAction I bet you're wondering how you were conceived.]]" [[{{Squick}} Duncan covers his ears and tries not to listen]]. The Creator/CartoonNetwork adaptation keeps that exchange.
* JerkJock: Troy plays it completely straight.
* {{Kaiju}}: Belloc and all of his rivals and subjects. They're even ''called'' Kaiju in-universe.
* LoveAtFirstSight[=/=]SingleTargetSexuality: Duncan towards Jenna.
** And apparently, [[LikeFatherLikeSon Belloc]] towards Margaret.
* LoveDodecahedron: Kenny likes Isabel, who likes Duncan, who likes Jenna, who's dating Troy. In the movie Jenna and Troy have broken up.
* MagicPants: So magic in fact that lava doesn't even singe them.
** Except for the very bottoms, which quickly rise to mid-calf.
** Adverted in the comic, in which his father's breath fries everything including his Fruit of the Loom.
* MaleGaze: Duncan towards Jenna twice.
* MamaBear: Margaret. She'll take on anyone who threatens Duncan. Including his father.
* MusclesAreMeaningless: Duncan is the size of a normal human, yet has physical strength on par with a full-sized Kaiju.
* MyGodWhatHaveIDone: Even though he doesn't exactly say it, Kenny feels this way after telling Duncan's secret at the dance.
** Jenna gets one after discovering that it was Duncan who helped her pay for the dance, and she just brushed him off.
* NeverHeardThatOneBefore:
-->'''Duncan:''' Kenny Rogers, huh? Do you know when to hold 'em, when to fold 'em?
-->'''Kenny:''' [''deadpan''] No. Not even a little.
* NoFlowInCGI: The movie has its moments of falling into this.
%%* OurDragonsAreDifferent
* PapaWolf: Let's put it this way, if you hate the city you live in enough to take them out - yourself included - hurting Duncan almost assures success.
* {{Parkour}}: The chase scene in the movie.
* ShirtlessScene: By comparison, the lava does remove his shirt nicely, though Duncan is quick to abandon it whenever he starts fighting.
* ShoutOut:
** Music/KennyRogers
** The way several of the kaiju move throughout the film is similar to the old Godzilla films.
** Belloc is the King of the Monsters, or Godzilla.
** One of the unnamed monsters that makes a brief appearance when Belloc names Duncan as his heir bears a definite resemblance to [[VideoGame/DragonQuestIV Death Pisaro]].
** The two villainous kaiju are named after biblical demons (Astaroth and Abbadon)
* SingleGirlSeeksMostPopularGuy: GenderFlipped, Jenna calls Duncan out on this.
* {{The Starscream}}s: Two of Belloc's subjects are not pleased with their king ordering them not to harm any humans. But mating with one is the last straw.
* StockScream: Used during the school chase scene.
* TheTalk: Barnes tries this in Volume 1 Issue 2.
** It has a few details, but is cut mercifully short by Belloc's new security system.
* ThouShaltNotKill: Duncan doesn't want to take of a Kaiju even if it nearly killed him.
%%* ThreeAmigos
* TookALevelInBadass: Duncan takes several over the course of the film.
* UltraTerrestrials: The Kaiju.
%%* WakeUpGoToSchoolSaveTheWorld
* YouDoNotWantToKnow: While many fans would like to know just how Duncan was conceived, ''he'' clearly does ''not''.
* YouSexyBeast: Duncan.
