'''''Kaijudo: Rise of the Duel Masters''''' is an {{Animesque}} WesternAnimation based on the ''Franchise/DuelMasters'' franchise.

The show's history is as follows: thousands of years ago, numerous creatures roamed the earth, each hailing from one of five Civilizations: Fire, Water, Nature, Darkness, and Light. The various myths of this world were given form due to the aforementioned creatures, from dragons and sea-serpents to even [=UFOs=].

At first, these creatures lived side-by-side with humans and everything was peaceful. Until eventually, certain creatures began to feel that man was growing too powerful too fast and started pulling for them to be enslaved. Thus began the Creature Wars which lasted for centuries. Said wars would understandably mar the present day outlook on the humans side toward creatures.

Seeing the inevitability of the wars tearing the world apart, five shaman warriors joined together. Each representing one of the five Civilizations, they preformed what is called ''Kaijudo'', which means "Way of the Strange Beast/(Creature)". They proceeded to strip the power from the five Creature Rulers and used it to create a parallel dimension know as the ''Kaiju Realm'' that is protected from earth by a barrier called the ''Veil'', where creatures reside in to this day.

And, just like that, the Creature Wars ended, and life began to evolve into what it is today.

These five shaman warriors took the near powerless bodies of the Creature Rulers and, putting them into a deep sleep, hid them deep underground. Henceforth, ''The Order of the Kaijudo Duel Masters'' began. Their charge was to make sure the Creature Rulers stayed in hibernation and also to guard the Veil, making sure nothing came out and keeping the earth and its people [[TheMasquerade ignorant]] that such things as "monsters" ever existed.

Fast forward to the present day. The Veil is weakening and creatures are coming through. The current generation of Duel Masters are kept busy sending the wayward beasts back home and sealing the rifts they came through, all the while not aware of what this could possibly foretell…

Our hero is fourteen year-old Raiden 'Ray' Pierce-Okamoto, who, along with his mom and grandpa, has just moved into a new apartment. Somewhat introspective and often bullied for his mixed heritage, he often longs for something more, as if he knows there's another whole world out there. This leads him to be on the "dreamy" side.

On his way home from school with his best friends, Allison 'Allie' Underhill and Gabriel 'Gabe' Wallace, his encounter with some bullies leads him to summon forth a Rumbling Terrasuar like the one he sketched the previous night from out of ''nowhere'' just by calling its name that he didn't even know. One thing leads to another, and the group ends up meeting a mysterious young man named Hector Chavez who then proceeds to rescue them by taking them on a short trip to the dangerous Kaiju Realm. This, of course, leads to the kids being shocked and upset when they get out. Chavez decides that the best way to explain would be to invite the kids to where he works, ''The Temple of the Kaijudo Duel Masters'', of which he is one of those Masters.

This in turn leads Ray to his destiny (Gabe and Allie as well, even if they don't realize it yet) and it leads ''us'' to this show.

''Kaijudo: Rise of The Duel Masters'' is an InNameOnly ContinuityReboot, with nothing in common with the original Japanese franchise (let alone the anime Animé or its GagDub of the first series). Well, except for many of the creatures, some of which have a [[SameCharacterButDifferent "same creature different look"]] kinda feel. The worst part? Some creatures were borrowed from the newer Japanese cards.

On the other hand, while it is a tie-in series to the newer card game[[note]]Although, as discussed below, it's technically the other way around.[[/note]], like [[{{Anime/Pokemon}} the Pokémon Animé]] or WesternAnimation/HuntikSecretsAndSeekers this is one of those few MerchandiseDriven series that doesn't (in some people's minds) go out of its way to advertise its merchandise tie-ins. This frees up space for the show to focus more heavily on its story and characters, and it definitely shows. Kaijudo is one of the more nuanced and well-written shows to come out of WesternAnimation in quite some time and is definitely worth a look if you're a fan of {{Mon}}s or action-adventure shows in general.[[note]]And/or if you don't care that this isn't the real Duel Masters franchise that (as of this writing) is still ongoing in Japan.[[/note]]

The aforementioned tie-in TCG was released around June 2012, under the name of [[{{TabletopGame/Kaijudo}} Kaijudo: Rise of the Duel Masters TCG]].

When the Hub refused to pick up a third season, ''Kaijudo'' ended on a cliffhanger on August 29, 2014, the same day the TCG was discontinued, and the series' website was closed down on December 3, 2014.

!!This show includes the tropes of:
* ActionMom: Ray's mom in the last episode (episode 26) of season 1, as well as the middle and end of season 2.
* AdultFear: Hoo boy. Let's see...
** Episodes 1-3: even though it's seemingly minor, your kid is being hassled for his [[MixedAncestry bi-racial heritage]] by bullies who are quite willing to be physically aggressive.
** ALL the stuff that seems to happen when the kids go into the creature realm.
** And last but not least "Betrayal": Janet Pierce-Okamoto [[spoiler: is forced to watch the building where she and Ray lived burn down while Ray and his same-aged friends are inside]]. Then, Saguru [[spoiler: finds out that he's really Ken Okamoto, Ray's father...which means he had just used and betrayed his own son as well as putting him in physical danger. To make it even worse, he wasn't immediately able to do anything about it since The Choten imprisoned him]].
** From a mentor's perspective, Master Chavez must have been devastated by how much damage could have been done to his students, because he [[spoiler: trusted Masters Brightmore and Jaha who have now [[FaceHeelTurn betrayed the council and sided with the Choten]]. Subverted with Jaha though]].
** Raiden, Gabe, and Allie are all drugged unconscious, and nearly get kidnapped or murdered by [[spoiler:Megaria's forces wile Allison's father is still asleep.]]
* AliensSpeakingEnglish: Although not all creatures can speak a language that the humans can understand, many can. One way to tell if a creature has some importance is if they can speak, Squeaky being an exception.
* AllMythsAreTrue
* AlmostKiss: Gabe with Sasha.
* AlwaysChaoticEvil: averted; it's clearly shown as the series goes on that none of the Civilization is either entirely good or evil, though [[BlueAndOrangeMorality they tend to have a different system of value than humans]].
* AncientArtifact: Each of the five civilizations has one powerful artifact, originally owned by the Creature Ruler Kings themselves. They each seem to be some form of InstantAllegianceArtifact and, as one would expect, The Choten's after all of them. They are as follows:
** [[PlayingWithFire Fire Civilization]]: The Sword of Fiery Cataclysm
** [[MakingASplash Water Civilization]]: The Helm of Ultimate Technology
** [[GreenThumb Nature Civilization]]: The Shield of Unity
** [[CastingAShadow Darkness Civilization]]: The Cloak of Dark Illusion
** [[LightEmUp Light Civilization]]: The Heart of Light
* AncientConspiracy: [[WhamEpisode "The Siphon"]] reveals [[spoiler: The 5 Beast Kings WILLINGLY gave their power to the original masters to power the veil for the sake of BOTH worlds, but for yet-to-be-revealed reasons, the masters backstabbed them, buried them alive, and created a myth of them awakening as Eldritch Abominations that exists to present day]].
* {{Animesque}}: Interestingly, the art director, [[http://www.usatoday.com/life/comics/story/2012-06-01/Kaijudo-Rise-of-the-Duel-Masters-animated-series/55333764/1 David Coleman]], said, among other things, that the main characters were designed with shapes in mind. Triangles for Ray since he's proactive, squares for Gabe since it's balanced like how he prefers things, and circles for Allie with occasional sharp corners to show her general soft and pacifistic nature, unless you get her really mad. Their main creatures, Bob, Gargle, and Squeaky respectively follow the same patterns.
** To compound this, both animation studios behind this show (Creator/MoiAnimation and Creator/DRMovie) are owned by Creator/{{Madhouse}}.
* AnnoyingYoungerSibling: Gabe's younger twin brothers Ronald and Donald constantly give Gabe trouble and almost fit the mold for BigBrotherBully because Gabe is so nonconfrontational.
* AnotherDimension: The Kaiju Realm.
* BadBoss: The Choten. He threw Fingers into the darkness realm and dropped Alakshmi from a high building roof. His treatment of Saguru before he had his memories returned can be counted as well.
* BatmanGambit: [[GuileHero Ray]] actually pulls off one against [[BigBad The Choten]] of all people by destroying the portal he's been using to abduct monsters then having [[GoryDiscretionShot Mighty Shouter take a dive in order to abuse his default teleporting back to the Nature Civilization to escape,]] costing The Choten ''weeks'' to repair it. [[TheAce No wonder he's the natural.]]
* BerserkButton:
** The Cyber Lords of the Council of Lagos hate being called "babies".
** AbusiveParents, especially fathers, really piss Tatsurion off more than he usually is.
* BigCreepyCrawlies: Like the [[ScaryScorpions Ambush Scorpions]] that Alakshmi is fond of.
* BigEater: An ExtremeOmnivore creature know as a Burn Belly; it consumes anything flammable than belches fire. After being injected with The Choten's mutagenic serum, any time they belch fire, they multiply. When the gang captures them in a container with a vacuum, one of the Burn Bellies eats the rest and [[OneWingedAngel transforms]] into Om Nom Nom, a giant, ferocious version of the Burn Belly.
** Midnight Crawler takes the ExtremeOmnivore trope to new heights by literally eating everything from plants and other creatures to entire tracts of land.
* BizarreAlienLocomotion: Gargle walks bipedally on his forelimbs while using his feet as hands.
* BlackAndGreyMorality: Toned down, but this is still visible in the opposition between the two sides; the Duel Masters see the creatures as dangerous weapons and follow a code of conduct when using them. One rule, for example, forbids the duelist from touching a kaiju. Another rule prevents the duelist from befriending the kaiju. (Through their interactions with Ray, Gabe, and Allie, some of Duel Masters have a change of heart.) In any case, the Duel Masters are still better than The Choten, who just wants to control all kaiju to serve his selfish purposes.
** The kids seem to be moving the Gray towards [[BlackAndWhiteMorality the White]] with their surprisingly effective tactic of ''befriending'' their kaiju.
* BondingOverMissingParents: Ray and Allie bond over Ray's DisappearedDad and Allie's MissingMom. That's how their friendship started.
* BreakTheFake: The Choten destroys the fake Helm of Ultimate Technology brought to him by Alakshmi to prove that it is such.
* ButtMonkey: Early on, due to her using creatures of types she wasn't experienced with, Allie never seemed to be able to keep a creature summoned for long before it was defeated. This lessens after she partners with Squeaky, but she still does loose her rather quickly at times.
** Fingers pokes fun at Alakshmi's many recent failures with The Choten showing great displeasure in them.
* CombatPragmatist: Trickery and deceit are the ways of darkness and those who are aligned with that realm tend to use such tactics. [[spoiler: Whether it's Allie disguising herself as Alakshmi to fool The Choten Choten, Razorkinder Puppet attacking his duelist Alakshmi when her back is turned, Megaria taking on the form of Allie's and Alakshmi's mothers to screw with their heads, or Jaha faking a betrayal just to defeat traitor Master Nigel when his back is turned.]]
* ContinuityReboot: For the dub of the original show and the Western franchise as a whole.
* CosmopolitanCouncil: The Order of the Kaijudo Duel Masters.
* CripplingOverspecialization: Ray's actually called out on this by Brightmore for wanting to summon [[TheBigGuy Tatsurion/Bob]] for the specifically ''stealthy capture of a flying monster,'' Ray gets flustered and does it anyway, [[LaserGuidedKarma goes temporarily blind for it along with Bob]], but [[TheAce of course, gets better and more varied in his approach so the lesson sticks]].
** The entire council are guilty of this, relying on one monster above all others. [[spoiler: The Choten realizes this, and summons them before summoning the Monarchs.]]
* CurbStompBattle: Though Gabe and Allie do put up the best fight they can, Alakshmi and Razorkinder quite frankly owns them. Ray fairs slightly better, but since he squandered his mana summoning Bob for menial labor, he isn't that useful himself. Razorkinder is defeated eventually, but [[TheBadGuyWins Alakshmi still gets away with Hissie]] [[DownerEnding in the end]].
** Though Hissie is rescued later on and Ray does curb-stomp Alakshmi in "The Siphon" after upgrading his Gauntlet. Its not long after that she falls from The Choten's good graces.
* DamselInDistress: Allie ends up playing this in episode 6 when a summoned creature that was defeated grabs her with its tongue as it is transported back to the Fire Civilization. It isn't long before she's sold to Lord Skycrusher as his dinner.
** Something similar happens to [[DistressedDude Artie, Allie's Dad]], in episode 18 "Duel Hard".
* DeadlyTrainingArea: The Choten of course has this in his bases.
* DeadpanSnarker: Several: Ray, Gabe, Allie, Master Chavez, Master Nadia, The Choten, Alakshmi, to name a few.
--> '''The Choten:''' Yes. A child will defeat an expert warrior who has survived for years in the Nature Realm... What a ''firm'' grasp on reality you have.
* DisappearedDad: Ray's dad. [[spoiler: Who was revealed to be Saguru in "Betrayal".]]
* EasyAmnesia: Master Nadia's Cyber Viruses, which she uses to control who knows what knowledge. Like erasing memories of the Kaijudo world from people who are no longer potential acolytes…
** The amnesia is so easy in fact that the good and bad guys both use Cyber Viruses liberally to control who knows what, especially in regards to regular humans as seen when The Choten has Alakshmi and Heller take over the bank to get the Helm of Ultimate Technology. [[spoiler: It happens to Heller at the end towards the end of the episode via the Duel Masters.]] In fact, Master Brightmore threatened to do the same to Ray, Gabe, and Allie during the episode "Night Moves" after their prank against [[AlphaBitch Portia and Maribel]] go completely awry. Though Gabe points out in a babble that that's no longer possible thanks to the immunity granted to them by the Cyber Lords as reward for saving the Helm of Ultimate Technology in "In the Deep Part II".
** It turns out that the Choten has access to Saguru's missing memories. He uses them to barter (later blackmail) services from him. [[spoiler: Unknown to Saguru, he took them in the first place.]]
* ElementalPowers: The five masters of the Kaijudo Order each specializes in creatures from one of the five Civilizations:
** LightEmUp: Master Nigel Brightmore and the Light Civilization. His primary creature is [[ShockAndAwe Ra-Vu, Seeker of Lightning]].
** PlayingWithFire: Master Hector Chavez and the Fire Civilization. His primary creature is [[LightningBruiser Gilaflame the Assaulter]].
** MakingASplash: Master Nadia Lobachevsky and the Water Civilization. Her primary creature is [[PsychicPowers Aqua Chaser, Rusalka]].
** GreenThumb: Master Benjirou Kimora and the Nature Civilization. His primary creature is [[TheBigGuy Mighty Shouter]]
** CastingAShadow: Master Jaha and the Darkness Civilization. Her primary creature is [[SoulPower Black Feather of Shadow Abyss]].
* ElementalRivalry: The five creature civilizations.
* EvenEvilHasStandards:
* EvilOldFolks: [[spoiler: In episode 25, the two oldest masters are the ones who side with the power hungry Choten. Allie even remarks about this. Subverted with Jaha who was {{fak|eDefector}}ing.]]
* EvolvingCredits: As much as a 30 something second opening can evolve. Certain scene changes start in episode 6.
* FaceHeelTurn: [[spoiler:Master Nigel]] (implied) at the end of episode 22 with his suspicious phone call to an unknown source. At the end of episode 23 "Heavenly Creatures," he is confirmed to have called The Choten and has officially joined the villains as well. This betrayal is revealed to the other Duel Masters toward the end of episode 25 "The Rising Part 1". [[spoiler: Master Jaha]] also does this toward the end of episode 25 "The Rising, Part 1" as well [[spoiler: only for Jaha to reveal she was faking it]].
* FaeriesDontBelieveInHumansEither:The creatures didn't believe humans were real before meeting them.
* FakeDefector: [[spoiler: Jaha. She pretends to join the Choten and even attacks Master Chavez and Gabe, then later helps them by knocking Master Brightmore, who had fully thought she had actually joined the Choten.]]
* FallenHero: The Choten, he was Nadia's teacher and Saguru's friend.
** [[spoiler:Masters Nigel and Jaha]] are this as well as of episode 25 "The Rising, Part 1". [[spoiler: Ultimately only Nigel was the fallen hero at the end of "The Rising, Part 2".]]
* FantasyCounterpartCulture: Mighty Shouter's [[ProudWarriorRaceGuy tribe]] are essentially Magical Native Americans, or at least Thorn-Bringer, and Skycrusher throws Romanesque Gladiator Games.
* FictionalCounterpart: San Campion is pretty much San Francisco.
* FierySalamander: Most Fire Creatures have reptilian motifs.
* FiveBadBand: Over the course of the season, The Choten's faction becomes this:
** BigBad: The Choten himself.
** TheDragon: Nigel seems to have taken up this role in season 2 as well as now being the Co-Dragon to Aqua Seneschal. Alakshmi was this until she betrayed the Choten and Saguru also was once this until his memories were restored. These two were once CoDragons to The Choten's main creature Aqua Seneschal.
** EvilGenius: The Choten plans his own schemes, so he doubles as TheEvilGenius and also a MadScientist.
** TheBrute: Heller. He's a petty thief who happened upon a Tech-Gauntlet and has a surprising knack for mana control. The Choten hired him to be extra muscle on missions, and he isn't treated with much respect otherwise. Saguru can also double as extra muscle if need be, but he's usually respected beyond just that.
** DarkChick: Fingers. At this point, he seems to be still around only because The Choten is not one of the most wasteful villain out there. [[spoiler: And not for lack of trying.]]
** SixthRanger: [[spoiler: As of the end of episode 21, "Like Father, Like Son", Carny joins The Choten's faction after learning that his father Alex is The Choten's financial benefactor and silent partner. All to impress dear old Dad...]]
* FiveManBand: The Order of the Kaijudo Duel Masters sorta fills this out:
** TheHero: Master Nigel, even though he's a rigid {{Jerkass}}, he's still the leader. [[spoiler: Not anymore given that he's sided with the Choten as of episode 25 "The Rising pt 1".]]
** TheLancer: Master Chavez, he is most opposite Nigel in his way of thinking, and is the most supportive of Ray and his friends.
** TheSmartGuy: Both Masters Nadia and Jaha fill this role; the former in historical knowledge and the like and the latter in an intelligence sense (i.e. spying).
** TheBigGuy: Master Kimora. He's second after Chavez in his support of the gang's ideals. Also TheBlacksmith Master Toji.
** TheChick: This is likely Lucy, an acolyte. She teaches Ray about nonviolent confrontation in Season 2. This role was originally filled by Joseph, a.k.a. Fingers, but he was TheMole working for [[BigBad The Choten]].
** SixthRanger: [[spoiler: Alakshmi, halfway through Season 2, joins the Duel Masters.]]
* GettingCrapPastTheRadar: Allie's comment to Steamstar Grapplog spraying her in episode 4.
--> '''Allie:''' That better have just been water…
** Episode 9 has this from the internet obsessed monster Gargle. Monster attacks are certainly dangerous, but that's not what the phrase "NSFW: NotSafeForWork!" [[TheInternetIsForPorn usually means]]...
** Sasha's interpretation of music like humans "coordinating their bodies".
* GladiatorGames: Lord Skycrusher's arena.
* GhostExtras: [[spoiler: In episode 25, "The Rising, Part I," Toji and a few temple acolytes are in a group with the heroes preparing to attack The Choten's base. ] However, there are no scenes where they actually participate in the battle that ensues (they don't summon anything, they are not being attacked, they don't talk, and nobody speaks to them). However, this group of extras is seen behind the heroes when they are all cornered.
* HalfBreedDiscrimination: Carny doesn't let Ray forget his ancestry. Additionally, Tatsurion is a wanted criminal because of his.
* HeadsIWinTailsYouLose: Even though [[spoiler: Fingers]] failed to steal the creature tablets, the creatures he set free for the diversion that weren't re-imprisoned are just more creatures The Choten can add to his arsenal.
* HeroicBSOD: Saguru. End of Episode 24 "Betrayal" [[spoiler: after the reveal that he's Ray's dad.]]
* HeIsNotMyBoyfriend: Alakshmi calls Ray Allie's boyfriend. She was about to say that he's not her boyfriend, but Alakshmi doesn't seem to care as she attacks her before Allie could even finish saying this trope.
* HighHeelFaceTurn: [[spoiler: Alakshmi was a female villain in Season 1, but she leaves The Choten's side at the end of Season 1. Eventually in Season 2, through a series of events, she becomes a probationary acolyte with the Duel Masters.]]
* HollywoodTactics: [[spoiler: A person with a duel gauntlet and sufficient mana theoretically can summon a creature (kaiju) if he or she knows the creature's name. After The Choten perfects his kaiju mind control collar, why doesn't he just summon and capture all of the Heroes' and Duel Masters' primary creatures instead of waiting until episode 25 to do it? Prior to episode 24, the Heroes' and Duel Masters did not know where The Choten's base was.]]
** He probably wanted to wait until they were off-guard or something.
* HonorBeforeReason: The masters' "No Touching the Monsters" rule is such that [[CastingAShadow Jaha]] chastised [[PlayingWithFire Hector]] for summoning a monster to fly them to rescue the kids in the Fire Civilization as "picking up the kids' bad habits" instead of [[ViolationOfCommonSense walking through desert/lava landscape when they were on a tight schedule]]. Had Hector not done this, they wouldn't have been able to pull a BigDamnHeroes and save the kids from being killed/recaptured.
* ImADoctorNotAPlaceholder: In episode 26, Gargle replies to Gabe, "I'm a mechanic, not a doctor."
Interspecies Romance: Gabe, a human, and Sasha, a Light Creature.
* InNameOnly: Has no connection or relation whatsoever with the actual Duel Masters franchise. Both this show, and its tie-in TCG attempt to justify themselves by using a different name, although the "Duel Masters" name is still used, but this time only refers to the main characters of this show.
* KickTheDog: Although keeping the Kaijudo world hidden is understandable, Master Nadia's attempt at erasing the group's memories still feels like this.
** Alakshmi [[spoiler:sending Allie's father to the Darkness Civilization.]]
* LaserGuidedKarma: The bullies, Carny, Driggs, [[MyFriendsAndZoidberg and the other one who never spoke]], gets their minds wiped of Ray summoning the Terrasuar by Nadia, after Gabe points out the unfairness of him, Allie, and Ray getting mind wiped and not the bullies.
* MadScientist: The Choten's ambitions to make creatures stronger through evolution makes him this.
* MagicalSecurityCam: Nigel's aptly named "Stalker Spheres" which are totally ''not'' spy cameras. Possibly justified by the Stalker Spheres being mobile rather than stationary… They can be hovering anywhere, so what's to say they ''wouldn't'' see the same things the audience does?
** Master Jaha's Ghost Spies serve a similar role.
* MeaningfulName: Many of the creatures' names as well as nicknames have some kind of meaning behind, obvious or otherwise.
* MistreatmentInducedBetrayal: Alakshmi betrays The Choten for finding out The Choten's real plan ([[spoiler: Alakshmi thought The Choten was going to tell the town about his triumph. Instead, The Choten launched Cyber Viruses to brainwash the townspeople and prepare them for the new world order.]]) and later being hurled off the elevated platform [[spoiler: for failing to retrieve the Sword of Fiery Cataclysm from Allie]]. Being thrown off the elevated platform was the more likely trigger for the betrayal.
** Moorna, Gatling Dragon bullied Tatsurion all his life and then tricked him into raiding his own mother village and had him arrested for defending his mother. Later, Moorna broke up her engagement with Brutalus after he lost his wings.
* TheMole: Fingers.
** [[spoiler: Master Brightmore.]]
* MonochromeCasting: {{Averted}}. The cast, both heroes and villains, are ethnically diverse. It was also brought up as a plot point regarding half-Japanese/half-white main character Ray and a racist bully.
* MyFriendsAndZoidberg: "Gargle has air-suits for friends! Friend G-abriel, friend Ray, friend Squeaky, err…Allie."
* MyGodWhatHaveIDone: Saguru in "Betrayal" [[spoiler: where it is revealed through a memory swarm that he is Ray's father. This came right after he A) lured Ray and his friends into an area that weakens creatures under the guise of helping them escape a fire, B) stole the Heart of Light from Sasha, rendering her unresponsive, C) broke Ray's ability to trust in him (though he may not be aware of that) and D) left the kids tied up in the creature realm]]. Needless to say, after Saguru learned who he really was, he was very...[[BerserkButton displeased]].
* NewSeasonNewName: Season one having the subtitle "Rise of the Duel Masters" changed in season two to "Clash of the Duel Masters" which comes from a new booster set from the card game.
* PowerUpgradingDeformation: The Choten's evolution virus.
* RedOniBlueOni: Master Chavez and Master Nigel (in that order)
* TheReveal: Different things, both major and minor, are revealed about both worlds and the characters that inhabit them as time goes on.
* SecretKeeper: [[spoiler: At the end of "The Rising Part II," the Council offered its condolences to Ray for his father being lost in the creature civilization (and possibly dead, although the last minute of the episode indicates otherwise). Ray's friends asked Ray what he would say to his mother and grandfather. Ray chose to tell them nothing and let them remember his father for who he was.]]
* SelectiveObliviousness: The Choten forces this on Saguru by picking and choosing which memories he rewards him for his successes. Before long, Saguru becomes more and more devoted to The Choten's Kaijudo WorldDomination schemes because they're {{necessary|Evil}} [[UtopiaJustifiesTheMeans to protect everyone]].
* ShipTease: [[MakingASplash Master Nadia]] to [[PlayingWithFire Master Chavez]] considering the frequent slips of [[FirstNameBasis calling him Hector]], using his [[LightningBruiser Gilaflame without his awareness/permission]] and being the one to call him out of his meditation in "The Siphon." The two get more moments like this later, when Master Chavez tackles Nadia down to save her from an impending attack. Later on, when Nadia needs to take [[spoiler: Allie's dad back to Earth]], Chavez calls Nadia by her first name. Also, there's Ray and Allie when they go to the school dance and summon creatures from the same civilization simultaneously and remark about it. Later on, we get the pairing of Gabe and Sasha, Channeler of Light. [[spoiler: At the end of episode 26, Master Chavez and Nadia kiss, and Ray and Allie hold hands: a tease no more. At least until the second season where Ray is {{oblivious|ToLove}} to Allie's feelings.]]
* ShoutOut: Several of the course of the series (Allie's "Get away from her, you ''witch!''", for example). The school dance in "The Unbearable Being of Lightness" is a massive homage to Literature/{{Carrie}}. Put together a couple of lines between Allie and Gabe in "Extracurricular Activities" for a shout out to [[Literature/HisDarkMaterials The Subtle Knife]].
** Allie once donned a Cloak that would swallow up anything and grant her power, and she is also associated with Darkness. [[WesternAnimation/TeenTitans This reminds you of a certain someone with the same description?]]
** "[[Film/HarryPotter Okay, so you were gone for the last couple years at Wizard School]] [[Franchise/KingdomHearts and learned to make drawings come to life from your sketchbook?]]"
** A kid named [[WesternAnimation/{{Ben 10}} Kevin uses power to get revenge on those who did him wrong]].
** Nigel looks a lot like an [[Film/HarryPotter Anti-Snape]].
** Grey Delisle voices a [[WesternAnimation/AvatarTheLastAirbender sadistic, fire-themed girl]].
** The Choten's Ship in "Siege" looks like [[Film/TheAvengers2012 Helicarrier]].
*** Also, in "Fallout", the kids have to [[Film/TheAvengers2012 gather together an unlikely bunch to stop an invasion, consisting of muscles, technology, a soldier, and they are all from different worlds than Earth]].
** Some of the main bullies consist of [[Series/MightyMorphinPowerRangers a fat guy and a skinny one]].
** The Choten's invasion with his Evolved Creature Army to Earth looks very similar to when [[Film/TransformersDarkOfTheMoon a large ship invaded the city]] [[WesternAnimation/TransformersPrime Optimus envisioned the worst-case scenario if Megatron had an Undead Army to take over Earth]].
** The Choten says that his friend has [[WesternAnimation/YoungJustice "seen the light"]].
** [[{{Franchise/Transformers}} Change-O-Bots.]]
* TagalongKid: How Gargle comes off towards Gabe when they first met. Additionally, Donald and Ronald are this to Gabe in "A Light in the Darkness" when he ends up essentially baby-sitting them. Never mind the fact that his immature brothers are 1 year ''older'' than him.
* TakingTheBullet: Saguru and Homunculon do this for Bob with disastrous results for them; made worse by the fact that it was in vain.
* TeethClenchedTeamwork: Nigel and Chavez's relationship seems to be this more often than not. Ray and Carny in episode 21 "Like Father, Like Son" after becoming trapped together in the Fire Civilization and are forced to work together to survive.
* TheGoodGuysAlwaysWin: Season 1 ending and most of the episodes had this.
* ThereCanBeOnlyOne: Empress Magaria says this word for word to Allie and Alakshmi about who will be her protegee before pitting them against each other.
* ToBeLawfulOrGood: The Duel Masters struggle with this, especially Master Nigel.
** [[spoiler: As of episode 25 "The Rising pt 1", Masters Brightmore and Jaha are now Lawful...and on the side of the Choten. Time will only tell what the other Masters choose.]]
** [[spoiler: As of episode 26, Jaha is still Lawful but was faking her defection as trickery and deceit is the darkness way]].
* TokenTrio: Ray (half-white/half-Japanese boy), Gabe (African-American boy), and Allie (white girl).
* TrademarkFavoriteFood: Bob (Tatsurion the Unchained) ''loves'' bacon.
* ViewersAreMorons: The only possible explanation for the creation of this franchise instead of bringing back the actual Duel Masters franchise.[[note]]Which didn't fare any better during its brief time in North America, due to the first anime series receiving a GagDub, and an outright {{Macekre}} of the second due to the first 26 episodes being reduced to 13, as well as a gag dub (with an American-only series created in between). Furthermore, later North American Duel Masters cards start having flavor text based on writing used for the gag dub.[[/note]]
* WeakenedByTheLight: Creatures of the Darkness Civilization.
* WealthyYachtOwner: Arthur Underhill has a yacht named "Piper" after his ex-wife.
* WhamEpisode: "Betrayal". [[spoiler: Ray's mom is an ex-Kaijudo duelist, Ray's father was a Duel Master, Ray himself was born in the Kaijudo realm, Saguru obtains the Heart of Light, and to top it all of, he's Ray's father.]]
** Quickly followed by episode 25 "The Rising pt 1" where [[spoiler: the Choten deprives ALL of the heroes of their signature creatures, Tatsurion is mutated by the Choten and Masters Brightmore and Jaha [[FaceHeelTurn defect to the Choten]]. In episode 26, Jaha had faked her defection]].
** [[spoiler: In "Unmasked" when Tiera and the Choten kissed and were revealed to be lovers.]]
* WhatMeasureIsANonHuman: Heroes and villains view the kaiju of the creature civilizations differently. [[BigBad The Choten]] [[NotSoDifferent lampshades]], where his side sees kaiju as [[HumanResources living batteries/slaves/tools]] to be controlled and used. The Duel Masters take a more naturalist approach, while following a code of conduct when using kaiju. Only Ray and his friends [[ThePowerOfFriendship think otherwise]], [[AncientConspiracy which is becoming a plot point]].
* WeUsedToBeFriends: Saguru says this to The Choten at the end of episode 24 "Betrayal".
* WorldOfBadass
* XMeetsY: Kaijudo seems like Franchise/{{Digimon}} and [[WesternAnimation/HuntikSecretsAndSeekers Huntik's]] biracial lovechild.
* YouHaveOutlivedYourUsefulness: [[spoiler: After one too many failures, The Choten has Fingers tossed into the Darkness Civilization to fetch one of his lost creatures. In episode 26, The Choten throws Alakshmi off the elevated platform where he was summoning the Creature Civilization Kings after she failed to retrieve the Sword of Fiery Cataclysm from Allie.]]
