[[caption-width-right:250:The conclusive arc of Bakugan.]]

''Bakugan Battle Brawlers'' is the story of six children who find Bakugan, which are these spherical toy-like things that transform into {{Mons}}, and must save the Bakugan's world, Vestroia. Some of these have their own spirits and are able to speak--all of the main characters, and most of the supporting cast, has one of these.

All and all, ''Bakugan'' could be seen as a combination of many different popular series. It is in varying parts reminiscent of ''Franchise/{{Digimon}}'' (the whole "{{save both worlds}}" thing--overall, it probably skews closest to ''[[Anime/DigimonTamers Tamers]]''), ''Franchise/YuGiOh'' (the sentient Bakugan is somewhat like the spirit monsters in ''[[Anime/YuGiOhGX GX]]'', and the game is played with cards), ''Franchise/{{Pokemon}}'' (in that ''Pokémon'' was one of the first "mon" series and this series features battling monsters contained in spherical devices), and ''Anime/{{Beyblade}}'' (MerchandiseDriven). There is one notable difference from these series, and that is that the non-human characters are able to talk while in ball form. (Go ahead, there's no instance where a Franchise/{{Pokemon}} ever talks to its trainer while inside a Poké Ball.)

The rules are hard to pin point, since they were never fully explained and [[ScrewTheRulesIHavePlot change whenever necessary]], similar to the first season of ''Anime/YuGiOh''. [[MST3KMantra Best to just leave it alone]].

Was followed by a sequel series, ''Bakugan: New Vestroia'' set a few years after the end of ''Battle Brawlers'', followed by a third series, ''Bakugan: Gundalian Invaders'', which was then followed by ''Bakugan: Mechtanium Surge'', which ended its broadcast in Canada and the United States. Additionally, there are three video games available on all seventh generation consoles.

A Reboot based on the Manga titled ''Baku Tech! Bakugan'' has started airing on Creator/TVTokyo and animated by Creator/{{Xebec}} as part of Oha Coro. However, this one is received poorly by the fans. It also spawned a sister series, ''Anime/{{Zoobles}}'' which is aimed more for the girly crowd.

Not to be confused with ''Manga/{{Bakuman}}''. Or [[Manga/{{Naruto}} Byakugan]]. Or even ''Manga/{{Bakuon}}''.

Collectible Card/Figure game [[{{TabletopGame/Bakugan}} here.]] and Video Games [[{{VideoGame/Bakugan}} here.]]
!!Tropes used in this series:

* AffectionateParody: Elfin/Minx Elfin to the titular character of ''Franchise/SailorMoon.''
* AesopAmnesia: Episodes 5 and 6 spend time showing Dan and Runo learning to work together as a team, only to begin bickering again at the end. [[LampshadeHanging Lampshaded]] by Tigrerra in the former.
--> '''Tigrerra:''' And I thought I'd finally understood them.
--> '''Drago:''' Tigrerra, we'll never fully understand humans.
* AlienInvasion: After [[BigBad Naga]] was destroyed in the first season finale, the next two seasons had extradimensional aliens as their main villains.
* AllLoveIsUnrequited: Mira is obviously into Dan, however, Runo beat her to the punch.
%%* AmbiguouslyBrown: Julie's ''entire family''.
* AndTheAdventureContinues: [[spoiler: ''Mechtanium Surge'', and the series as a whole, ends with Dan and Drago sailing off into the distance, both sure that wherever the wind takes them, adventure will follow.]]
* ArtEvolution: ''Gundalian Invaders'' finally stopped with all the OffModel-[[BuffySpeak ness]], but the LipLock is still heavily present.
* AstonishinglyAppropriateAppearance: Each of the characters wears attire that has matching colors with their attribute (except for [[spoiler:Alice]] in the first season), and it occurs every seasons. Coincidence? [[ColourCodedForYourConvenience Can't think so]].
* TheArtifact: Julie in ''Gundalian Invaders''; the sole reasons for here existence there was to give Jake some pointers early on and to remind the viewers that the original cast was more gender-balanced.
* BadFuture: [[spoiler:[[TheBadGuysWin Coredegon and the evil Mechtogan win]], destroying Bakugan City and everyone in it, he then goes to New Vestroia and kills off all the Bakugan. Thankfully, the Brawlers SetRightWhatOnceWentWrong by going back in time to stop him in his tracks right as he's about to leave to do all this.]]
* BareYourMidriff: Julie and Runo. Runo stops after season 1 while Julie continues until season 4.
%%* TheBaroness: Mylene, Kazarina
* BeautyEqualsGoodness: While both alien races are able to disguise as normal humans, the Neathians tend to look more human-like and more conventionally attractive than the Gundalians, who often have BigOlEyebrows or FaceOfAThug.
%%* BelligerentSexualTension: Dan and Runo.
%%** Shadow and Mylene in ''New Vestroia''.
* BecomingTheMask: [[spoiler:After Alice discovers that she is really Masquerade, she initially stops brawling all together, but eventually is able to fight using Masquerade's abilities while remaining herself.]]
* {{BFG}}: Ren's Boomix battle gear and Kieth's Zukanator Battle Gear.
* BigBad: Each season has a new BigBad. Season 1 had Naga, season 2 was King Zenoheld, season 3 was Emperor Barodius, and season 4 has Mag Mel in the first half and Wiseman and Coredegon in the second[[spoiler:, although it turns out Mag Mel was Barodius and Wiseman was a disguise for Coredegon.]]
* {{Bishonen}}: There are many attractive boys in the series, including Shun, Klaus, Spectra, Gus, and possibly Jesse and Hydron as well.
%%* BoisterousBruiser: Jake
* BoobsOfSteel: Julie is unusually well-developed for her age, and her Bakugan partner Gorem is TheBigGuy.
* BrainwashedAndCrazy: Dr. Michael as Hal-G. On top of that, it seems like ''everyone'' is getting brainwashed in ''Gundalian Invaders''
%%* BrattyHalfPint: Nene.
* CallingYourAttacks:
** "Ability Card Activate! (Insert card name here)!"
** And, of course: "Gate Card, Open!!"
* CatchPhrase: Akwimos's "Cool is the rule, dude!"
* CameFromTheSky: The Bakugan Cards
-->'''Dan:''' My whole world changed one day when all these random cards started raining down everywhere! At first they seemed harmless enough so a bunch of us kids invented this cool new game... That's when we realized those cards weren't so harmless after all!
* CharClone - Spectra Phantom wears mostly red (including a mask), is blonde, is The Rival, [[spoiler:and is actually named Keith Clay, the older brother of Mira Clay]]. Also, Masquerade doesn't have a thing for red nor does he [[spoiler:err, she]] have a younger sister, but he is mostly this trope.
* CombinationAttack:
** Various special attacks can be used to boost the power level of your Bakugan if you're attacking with two Bakugan of elements next to each other on the elemental wheel...or across from each other on the wheel...or with the three that make up a triangle on that wheel. So there's a pretty good chance that any time two of the Brawlers are dueling together, they'll be able to use a combo attack.
** Hell, seeing as how regular (normally Aquos) Preyas can change his element at will and his evolution manifested in the form of a ''second'' Bakugan, Haos Preyas Angelo/Pyrus Preyas Diablo, Marucho is able to pull off the Aquos/Pyrus/Haos triangle attack all by himself--or would be, if any of the non-sentient Bakugan appeared at all during New Vestroia.
* CombinedEnergyAttack: [[spoiler:Dragonoid Destroyer gets powered up by the energy of the bond between all humans and Bakugan on earth, activating his GoldenSuperMode and allowing him to ''obliterate'' Mechtavius Destroyer in one hit.]]
* ContinuityPorn:
** ''Mechtanium Surge'' has been this so far. Characters from all seasons have been making reappearances in important roles, including Spectra and Preyas (well, half of him, Preyas Angelo[=/=]Diablo is nowhere to be seen), Gundelia and Vestoria have been revisited for multi-episode arcs,and [[spoiler:Mag Mel is the previous season's BigBad, Emperor Barodius]]. And the season isn't even ''halfway over yet!'' Also a case of TropesAreNotBad, as this is one of the best things the season has going for it so far.
** The episode 'Blast from the Past' in the second half of the season is a glaring example. It brought back both Preyas forms, Minx Elfin, Skyress, Gorem, Ingram, the list goes on, but it's basically every partner Bakugan except Drago from previous seasons. [[spoiler: It's a shame they were just there to get beaten though...]]
* ContrivedConvienience: Dan, Runo and Shun all live in the same country. {{Subverted|Trope}} in that Dan and Shun knew each other as children.
* CoolMask: Masquerade and Spectra both wear these.
* CrystalDragonJesus: Drago, oh so much. Bonus points for being a literal dragon and [[spoiler:turning into an actual crystal at the end of the first season.]]
* CulturalTranslation: ''Gundalian Invaders'' seems to have taken this literally, seeing as how Dan's new place of living, Bayview City, has American Football, Burger Joints, has people with English names like Jake, and he now lives fairly close to Julie, it can be assumed that he's moved to America.
* DarkerAndEdgier:
** [[spoiler: Season 2 of New Vestroia made battling more lethal.]]
** ''Gundalian Invaders'' involves an actual ''[[WarIsHell war]]''. Permanent character death is a common sight.
** ''Mechtanium Surge'''s first BigBad, Mag Mel, was imprisoned for ''genocide'' and seeks to ''[[OmnicidalManiac destroy the entire universe!]]''
*** The second BigBad outdos him by [[spoiler:''leveling an entire city and killing off all the Bakugan!'' To clarify, there's no attempt to cover up that destroying the city killed millions of people, in fact its ''very'' heavily implied it did. Thank goodness the Brawlers SetRightWhatOnceWentWrong.]]
* DarkIsNotEvil: [[spoiler:Alice]] and Ace use Darkus-attributed Bakugan.
** DarkIsEvil: ...On the other hand, we have Hal-G, Masquerade, Barodius and Ren. [[spoiler:Ren turns good later, and Masquerade decides to help Dan during their final brawl together before fading away.]]
* DarkSkinnedBlond: Julie is the white-haired variant.
%%* DeadpanSnarker: Preyas. Gets even worse with Preyas Diablo.
* DefectingForLove: Lync turns against the Vexos out of love for Alice.
* DefectorFromDecadence:
** [[spoiler: Downplayed, but Masquerade decides to help Dan battle the remaining Doom Beings at Alice's behest, but even by his own admission he will do it only once.]]
** [[spoiler: Volt and Lync both leave the Vexos because they want no part in Zenoheld's new genocide plans. Lync even [[HeroicSacrifice sacrifices himself to deliver the plans to Alice.]]]]
** Mira forms the Resistance after discovering the Bakugan [[MadScientist her father]] was torturing was intelligent.
* DefeatMeansFriendship: Zenthon, a Mechtogan spawned from Drago's out of control power, was a rampaging beast until finally, Drago managed to best him in battle, resulting in him coming under Drago's control. Though in this case, it was described as "breaking a wild horse" and showing it whose the master.
* DemotedToExtra:
** Julie, Runo and Alice in ''New Vestroia''. [[spoiler:Okay, maybe more like demoted to second tier, but until they regain the ability to brawl, the trope still applies.]]
** [[spoiler:By the time of ''Gundalian Invaders'', Runo and Alice don't even appear. Runo's mentioned in a picture, but that's about it.]]
** Then, [[spoiler: Runo returns as a (fairly) main character in the second half of ''Mechtanium Surge'', but she's still retired from battling.]]
%%* DisneyDeath: [[spoiler:Gus.]]
* DistaffCounterpart: Elfin, to Preyas.
* DontCelebrateJustYet: This phrase gets thrown around the whole series from time to time during the battles, especially when someone gets overconfident that they're strategy is going to win.
%%* DoubleAgent: [[spoiler:Mira.]]
%%* DudeWheresMyRespect: Hydron is ''made'' of this trope.
* ElementalPowers: Pyrus (fire), Aquos (water), Ventus (air), Subterra (earth), Haos (light), and Darkus (darkness). These powers are drawn from Infinity (positive energy), which allows Bakugan to use all elements, and Silence (negative energy), which amplifies dark power to extreme heights. When combined, they form Perfect energy, and a Bakugan can use any element to its fullest, or even bend space and time.
* EntertaininglyWrong: Julie thinking that Shun is helping Masquerade is not helped by the fact that his grandfather, who resembles the villain Hal-G is visiting town.
* EvasiveFightThreadEpisode: Episode 2 of ''New Vestroia'', after a bit of exposition, turns into a fight between Dan and Ace that never gets resolved.
* EvenEvilHasStandards:
** Masquerade's first partner, Reaper, [[spoiler:objects to being sent to the Doom Dimension]].
** Gus seems visibly appalled at Mylene throwing away Elico and Brontes because of [[spoiler:the fact they're sentient]]. Subverted, in that he goes on to [[spoiler:put them through [[BrainwashedAndCrazy brainwashing and torture]].]]
** Volt and Lync [[DefectorFromDecadence leave the Vexos]] once they begin their master plan [[spoiler:[[OmnicidalManiac to destroy the universe]].]]
* EverythingsBetterWithPrincesses: Princess Fabia of Neathia, the Haos brawler for ''Gundalian Invaders''.
* EvilTwin: Naga, to Wavern. (They're ''fraternal'' twins, by the way.)
* EvilVsEvil: [[spoiler:The evil Mechtagan vs the Nonet Bakugan and Wiseman II.]] The episode is even ''called'' "Evil Vs Evil".
* EvolutionPowerup:
** All of the main Bakugan evolve at least once, and Drago and Hydranoid evolve twice. Then, Drago succumbs to something we could deem Spontaneous Evolution Syndrome, and hits an absurd level of transformations to the point [[{{Narm}} it gets cheap]] to know he's just gonna ''keep'' evolving like crazy each season.
** As of now, [[spoiler: Drago has evolved nine times and gone through ''ten'' forms, adding in one backslide in power after separating from the Perfect Core. So far, if the show is truly over with. The gimmick's been beaten like a dead horse and serves as the prime excuse to make Drago [[DeusExMachina tougher than the resident villains of each season on the fly]] ([[MerchandiseDriven and sell an assload of new toy variants of the main character Bakugan that kids will easily recognize if he's their favorite, thus making their parents shell out money time and time again]])]].
*** Season 4 is Deconstructing this rather hard. Drago's latest evolution is way too much for him to control and is causing ''a lot'' of problems. It's created an unstoppable engine of destruction that's kicking everyone's butts, threatening to set [[BigBad Mag Mel]] [[SealedEvilInACan out of his prison]], and [[ArsonMurderAndJaywalking ''completely ruining''' Dan and Drago's reputation with their in-universe fanbase]] because they're fighting poorly due to needing to focus on controlling their power. Then, [[spoiler: he evolves ''AGAIN'' to solve the problems this new evolution caused, but for the last time]]. Basically, the people behind the series didn't really care how much they abused the evolution gimmick.
*** Actually, by the time Drago evolved for the final time, he had overcome the issues caused by his evolution.
* ExposedToTheElements: Julie and Runo go to visit Alice in ''UsefulNotes/{{Moscow}}'' in ''New Vestroia'', still wearing the same clothes as always, and don't appear to be having any trouble at all. {{Fanservice}}, anyone?
* {{Expy}}:
** As far as anyone's concerned, Spectra is Masquerade 2.0. both wear eye-covering masks, have flamboyant blonde hair, seek to create the "Ultimate Bakugan", and have shocking secret identities.
** That Spectra...[[CharClone HE IS A CHAR!!]]
** About ''Anime/MobileSuitGundam'', Hydron pays a passing resemblance to Hilling Care. He also resembles N from ''[[Franchise/{{Pokemon}} Pokemon Black N White]]''.
** Julie looks a lot like a young [[Anime/CodeGeass Villetta Nu]].
*** Speaking of ''Anime/CodeGeass'', when Dan's new silver outfit makes him look a lot like Suzaku.
** Shun is a top level battler in his chosen toy-using sport, has real-world fighting skills, plays on AllGirlsWantBadBoys for the fans, and is a loner. He's Kai with a different look. He even had issues with working with his team and came around due to his connection with his Bakugan (like Kai did with Dranzer).
** Dan in his first season outfit looks a lot like [[VisualNovel/HigurashiWhenTheyCry Keiichi Maebara]].
** Elfin. [[http://images.wikia.com/bakuganusers/images/b/b0/Elfin_Anime.jpg Don't you dare say]] [[http://aja510.tripod.com/SMoon.jpg that she is not an expy of Sailor Moon]].
** Gunz looks a lot like [[Anime/YuGiOh5Ds Jack Atlas]].
** Billy is a dead ringer for a younger [[VideoGame/FatalFury Terry Bogard]]. [[http://www.youtube.com/watch?v=oNLdCmZblRQ Dubbing over Billy's lines with Terry's]] seems ''completely natural.''
** Dan looks a lot like [[Anime/DigimonFrontier Takuya]] - they wear similar clothing and have the same element.
* {{Fanservice}}:
** Very subtly. While they've taken them out of the action, Julie and Runo aren't ''completely'' gone in ''New Vestroia'', and any time Mira is seen from the side, it will inevitably be from [[ZettaiRyouiki the right side with the knee-high boot]]. Marketing to children while including some TurnOnTropes... well played, Sega/Spinmaster.
** 80% of the boys are {{Bishounen}} to some extent. Other parts is mixed between cute little boys and dude with HeroicBuild. PeripheryDemographic much? Since this series ambiguously run on GenericCuteness, this is debatable but EFFECTIVE.
** [[TheSmurfettePrinciple Fabia]], [[{{Bishonen}} Ren]] and [[MrFanservice Jake]] all have many moments throughout ''Gundalian Invaders''.
* FashionableAsymmetry: Mira, with ZettaiRyouiki on the right leg.
* FingerlessGloves: Ace, Dan, Marucho, and Hydron in ''New Vestroia''.
** In the original series, every Bakugan player. Like in season 2 of Anime/{{Beyblade}}, they're obligatory equipment.
*** Strangely absent from the third season so far.
* FinalBossPreview: Mag Mel attacking the Brawlers himself during his assault on Gundalia. Even Dan and Drago aren't powerful enough to take him down and get their butts kicked.
* ForgedByTheGods: Mag Mel's armor was created by what amounts to the God of the Bakugan, Code Eve. However, she isn't doing him any favors because [[spoiler:she created it [[MadeOfEvil from Emperor Barodius' evil]] in order to seal him inside it.]]
* {{Foreshadowing}}:
** The first season drops hints to Masquerade's identity [[spoiler:as Alice]] like there's no tomorrow.
** New Vestroia spends the last few episodes setting up Gundalian Invaders with [[Spoiler: Bakugan Interspace, the phantom data, the Bakugan generated by said phantom data and the introduction of battle gear]]
** In Mechtanium Surge, Razenoid's head heavily resembles Dharak's. This sets up the reveal that [[spoiler: Razenoid IS Dharak and Mag Mel is Barodius]].
* FromBadToWorse:
** [[spoiler:When they delete Bakugan Interspace]] in an attempt to kill Mag Mel, he makes it to Earth with his army anyway. Oh, and ''Razenoid evolved!''
** When Dan accuses Gunz of being Wiseman, when he really isn't, the team turns on him. Gunz responds by ''actually becoming Wiseman.'' Thankfully, it got straightened out.
* FusionDance: ''Mechtanium Surge'' introduces this, allowing two Bakugan to merge together. They split in half and then each half merges with half of their partner. In an unusual take on this, they two remain separate, but both gain traits and powers from their fusion partner.
* GenderBender: [[spoiler:Masquerade is clearly a guy, especially with his deep voice, but when his mask is taken off, he becomes ''Alice.'' Comes with a [[ImpossiblyCoolClothes nifty]] clothes change too.]]
* GettingCrapPastTheRadar: Episode 17 - Preyas says the magic word close to 8 minutes in. ([[http://www.youtube.com/watch?v=SO7lpMBl2fw For proof, go to 8:05 and play it from there.]])
* GirlishPigtails: Runo fits the {{Tsundere}} archetype.
* GodzillaThreshold: Mag Mel's threat is so great that [[spoiler:the group has to resort to ''completely deleting Bakugan Interspace'' in an attempt to stop him. And it ''doesn't work!'']]
* GogglesDoNothing: Dan's goggles are usually just there to be stylish, but he used them a grand total of ''one time'': shielding his eyes from a blinding Haos attack.
* GoldenSuperMode: [[spoiler:Dragonoid Destroyer obtains this after being powered up by the combined energy of the bond of every human and Bakugan on Earth. His power level at this point is ''infinite''.]]
%%* GoodAngelBadAngel: Preyas Angelo and Preyas Diablo.
* HeelFaceTurn: [[spoiler:Masquerade, who becomes a secondary personality/spiritual ally for Alice]]
** [[spoiler: And Spectra Phantom/Keith Clay with Helios and Gus Grav with Vulcan]]
** [[spoiler: Volt Luster and Lync Volan of the Vexos]]
** [[spoiler: Hydron joined the Brawlers and sacrificed himself in order to stop his father, King Zenoheld]]
** [[spoiler: Most of the members of the Twelve Orders:]]
*** [[spoiler: Ren Krawler and Linehalt]]
*** [[spoiler: Nurzak and Sabator, who later becomes Prime Minister of Gundalia]]
*** [[spoiler: Mason Brown and Avior]]
*** [[spoiler: Lena Isis and Phosphos]]
*** [[spoiler: Jesse Glenn and Plitheon]]
*** [[spoiler: Zenet Surrow and Contestir]]
*** [[spoiler: Sid Arkale willingly releases himself to fall to his death after giving Rubanoid to Ren, and Rubanoid also become the new Guardian Bakugan of Linus Claude after the passing of Neo Ziperator]]
** [[spoiler: Worton and Betadron of the Nonets after Coredegon/Mechtavius-Destroyer commits genocide against humanity and the Bakugan]]
* HerHeartWillGoOn: [[spoiler: Fabia's fiance was killed in action some time before meeting the Brawlers.]]
* HeroicSacrifice:
** Drago has to merge with the Perfect Core at the end of ''Battle Brawlers'', losing his physical form. He gets better at the start of ''New Vestroia''.
** Elico sacrifices his life in battle with Farbros to protect Gus. Soon, Hexados follows suit and leaps in front of a lethal blast to save Vulcan.
** [[spoiler:Prince Hydron makes sure his father goes down with the quickly collapsing ship]] at the end of ''New Vestroia''. As for [[spoiler: Professor Clay, he chooses to stay behind in the Alternative when he gets trapped, rather than have Mira and Keith risk their lives to save him.]]
** [[spoiler: "Surge": Kodokor lets himself be slain so that a combined Spatterix and Stronk can take down Mechtavius Destroyer in the havoc of his explosive death, and likewise, the latter two buy time for Betadron and Gunz to escape harm.]]
** [[spoiler: Also in "Surge", Worton and Betadron stay behind in the time stream to let the Brawlers travel back to the past, knowing they might perish.]]
* HoistByHisOwnPetard: Naga kicked off the series by absorbing too much energy from the Silent Core. [[spoiler: When he dies, it's also by absorbing too much power.]] The BT System of New Vestroia also explodes by absorbing too much power. [[spoiler: Phantom Darak and Barodius also explode from, guess what, absorbing too much power.]] Now, in ''Mechtanium Surge'' there is a creepy guy who is demanding power from the main characters. Any bets on what'll happen to him?
** [[spoiler: Guess what! HE EXPLODED.]]
%%* HotBlooded: Dan.
* HumanAliens:
** The Vestals look no different from normal humans aside from their eyes.
** Subverted in the case of the Nethians and Gundalians- they're only using illusions to make themselves appear human to blend in with humans on Earth.
* HurricaneOfPuns: One episode has Masquerade spewing non-stop theater related puns, eg: "The stage is set, and the performers are all here!" "And now, the final curtain!" "Time for an encore!"...
%%** Jesse. Just... Jesse. [[spoiler: EVEN HIS SUPPOSED LAST WORDS!]]
* HumongousMecha: The Mechtogan. There are also the larger Mechtogan Titan.
* IllBoy: Joe lives in the hospital in the first episodes where he appears, but he recovers thanks to Wayvern's healing powers and she becomes his Guardian Bakugan.
* InactionSequence: Like with most [[TabletopGame/YuGiOh card]] and [[Anime/{{Beyblade}} toy]] based games. Although when it's averted, it's averted ''awesomely''! [[spoiler: Laser-Sword Fight!]]
* IncestSubtext: Mira, Keith...[[NotADate mere dinner or a date?]]
** In the finale, [[spoiler:they live together, and Gus was nowhere to be seen]].
* {{Invocation}}:
** "Gate Card, Set!", "Bakugan Brawl!", "Ability Activate!"...
** During ''New Vestroia'', "Ability Activate!" makes up 80% of the dialogue. And no, that is not an overstatement, it really does.
* KarmicDeath: All of the {{Big Bad}}s (sans Mechtavius Destroyer) have been done in by their own doing. [[spoiler: Naga's own energy absorbing powers were used to overload him, causing him to explode. Zenoheld's own ultimate weapon exploded with him inside it while [[TheDogBitesBack his son who he treated like crap keeps him inside it]]. Barodius met his end when the object he spent the entire season trying to get proved far too much for him to handle and seemingly vaporized him and his Guardian Bakugan. Instead, they turned into Mag Mel and Razenoid, but then were finally beaten for good and destroyed entirely... again, by Mag Mel's suicidal attempt to take Dan down with him by launching all his hi-jacked energy at him... only to fail.]]
%%* KilledOffForReal: [[spoiler: Sid, ALL of the twelve orders but Nurzak]]
%%** To date, all of the {{Big Bad}}s.
%%* LaughingMad: Shadow Prove
* LampshadeHanging: Typical dynamic: Dan is surprised by something [[ParrotExposition so he repeats what he just heard.]] [[DeadpanSnarker Shun replies that that's exactly why whoever said that said so.]]
* LifeMeter: In the second series onward.
* LightIsNotGood:
** Some of the villains use Haos-attributed Bakugan.
** Same goes for Bakugan: Lumagrowl in particular ''openly praises the benefits of cheating''.
** Naga, though lacking an attribute, is pure white.
%%* LipLock
* [[{{Filler}} Loads And Loads Of Filler]]: Feels like each arc can be condensed into ''a'' '''''third of its length'''''.
%%* LongDistanceRelationship: Julie and Billy.
* LukeIAmYourFather: Spectra is [[spoiler:Mira's older brother Keith.]]
* [[MadScientistsBeautifulDaughter Mad Scientist's Beautiful Daughter]]:
** Mira subverts this; she's ''already'' leading LaResistance at the start of ''New Vestroia'', and she's not an only child.
** Alice, a Mad Scientist's Beautiful ''Granddaughter'', plays this straight. Well, sort of. Her grandfather, Michael, was taken over by negative energy after an accident with a dimensional transporter and became the evil Hal-G, and she tried to defend him, and was herself being used by him, first by being turned into Masquerade and then by being tricked into believing that Michael was [[IKnowYouAreInThereSomewhereFight in there somewhere]].
* MagicalGirl: Elfin. while it wasn't so noticeable at first, when she evolved into Minx Elfin, she invokes this trope so much that she's practically become a [[AffectionateParody direct homage]] to Sailor Moon, complete with InTheNameOfTheMoon style phrases. It's so blatantly obvious now that she even copied one of ''Anime/SailorMoon'''s signature poses.
* MerchandiseDriven
%%* MissionControl: Joe.
* MoreDakka:
** The entire premise of the Battle Gear is to load a Bakugan down with firepower. Sometimes, it involves [[HumongousMecha giant mechanical Bakugan]] that can [[CombiningMecha combine]] into battle armor.
** Helios takes it to a major extreme by implementing Vestal technology into his body to become a technorganic dragon, improving it as he and Spectra see fit. The first Battle Gear he uses (also first in the series) is the Twin Destroyer, a pair of rapid-fire, quadruple-barreled machine gun turrets. The next atep up is the Zukanator, a missle-size photon laser that can rip through tempered steel plates like tinfoil.
** The Vexos use mechanical Bakugan as a total replacement to the living ones, believing they can craft bigger weapons of destruction than Bakugan themselves can unleash. If need be, they will force evolution or experiment to make them deadlier.
** King Zenoheld starts off with Farbros, a mechanized dragon with immense firepower. It turns into a full-fledged battle suit when the Assail System is combined with it. But the most fearsome weapon he ever used was the Alternative, a continent-sized starship with garrisons of disposable attack bots, ''SAVAGE'' firepower that ''ripped a gaping hole in a moon'', then ''vaporized said moon", and the power to wipe out planets at the flick of a wrist.
** Drago's constant use of Battle Gear himself, plus his unbelievably frequent evolution rate powers him up time and time again.
** Dragonoid Colossus had Battle Gear he could summon to use on his back like battleship guns. Axator even managed to link up to Drago. [[spoiler: If Colossus didn't get destroyed, we might have seen more of his Battle Gear used by Drago.]]
** Mechtogan are summoned in response to the need for more power to defeat a foe, starting with Zenthon- but he's stuck in an UnstoppableRage until put under proper control. When that isn't enough, immense willpower can cause a Mechtogan Titan to appear. When a Brawler's will reaches its peak, the strongest Mechtogan can be summoned- ones that can combine. The strongest of these is Dragonoid Destroyer.
** Bakugan can fuse with other Bakugan to combine powers and abilities, or absorb objects of power to grow stronger and harness their might.
** Kazarina splices ancestral DNA into Dharak for the sole purpose of his evolution to be on par with Drago.
** Cordegon, Slycerack, Exostriker, and Mandiblor act as minions to the Nonets to use their power while they recuperate. These Mechtogan combine into the terrifying Mechtavius Destroyer when united, capable of sucking in the power of defeated Bakugan. In response to this, [[spoiler: Chromopod's ability to strip these Mechtogan from Cordegon's control allows for the fusion of Quatrogan.]]
** The strongest power of Bakugan is the ability to resonate with the willpower and courage of other Bakugan and humans to tap into their greatest and most decisive powers, often the result being evolution. In Drago's case, anytime a foe causes both him and Dan to force themselves to new heights, their wills fire up, and almost certainly, it leads to another evolution. They get tested so much by powerful forces and battle challenging evils so frequently, transformations are Drago's instinctive response to finding more strength: he and Dan ''will it into existence.''
* MotionlessChin: Played painfully straight, akin to one of [[Manga/KenichiTheMightiestDisciple TMS' other series]].
* NeverSayDie: Shun's mom in the dub. Mostly subverted otherwise.
* NiceHat: On the final episode of ''Battle Brawlers'', Dan and Runo go out on a date, with the latter sporting a whole new hairstyle and matching white dress. Somehow the first thing Dan notices on Runo is her [[http://www.youtube.com/watch?v=LjCCdcsAfzg cool looking hat]].
* NiceJobBreakingItHero:
** Code Eve, the creator of the Bakugan, gave Drago an upgrade as a reward for defeating season three's BigBad. This ends up being too much for him to handle, resulting in Drago creating a Zenthon. This also links Dan and Dragon to [[BigBad Mag]] [[SealedEvilInACan Mel]], allowing him to absorb energy and begin to escape his prison. Yeah, real nice job there!
** Thanks to Mag Mel, nearly everything the Brawlers do in ''Mechtanium Surge'' turns out to be this. Not really their fault though, Mag Mel is just that good at XanatosSpeedChess.
* [[NonActionGuy Non Action Girl]]: Alice for the majority of ''Battle Brawlers''--first because she doesn't have any Bakugan, and then because she's too busy {{Wangst}}ing about [[spoiler:having been unknowingly controlled by Masquerade.]]
* NotEvenBotheringWithTheAccent: Despite half the characters coming from every corner of the world (e.g. Alice is from Moscow), everyone has an American accent.
* NotSoDifferent:
** Dan and Masquerade both have a dragon-based partner who evolves by getting stronger and are the first two characters shown with talking Bakugan.
** Baron and Volt both live with several young children and prefer Haos-attributed Bakugan.
%%** Eventually, all of the first season girls.
* OfficialCouple: See VictoriousChildhoodFriend below.
* OffModel: The show can have quality issues. And considering that Creator/TMSEntertainment animated it, that's a large stretch. To be more precice, the OffModel is most noteable with Masquerade, Komba and Julio. In Masquerade's case, it looks almost as though the mask is getting bigger in some shots, or that the mask is sliding up and down his face. With Komba and Julio, it's mostly the nose.
* OnlyThePureOfHeart: A certain security system works like this.
* OurDragonsAreDifferent: This anime loves this. In no specific order: [[[http://images.wikia.com/bakugan/images/a/ae/Pyrus_Neo_Dragonoid_%281%29_D.E..jpg Dragonoid]], [[http://images.wikia.com/bakugan/images/9/9b/Viperhelios00.jpg Helios]], [[http://images.wikia.com/bakugan/images/d/d7/Ddddrrgn.jpg Rubanoid]] [[http://images.wikia.com/bakugan/images/0/02/Plithyprww.jpg Plitheon]] [[http://images.wikia.com/bakugan/images/e/e9/Avior_Anime.jpg Avior]] [[http://images.wikia.com/bakugan/images/8/83/Dharakmode.png Dharak]] [[http://images.wikia.com/bakugan/images/a/ab/Wavern_Dragon.JPG Wayvern]] [[http://images.wikia.com/bakugan/images/7/74/Screen_Shot_2011-12-27_at_5.13.01_PM.JPG Naga]] oh gosh [[http://images3.wikia.nocookie.net/__cb20091213222143/bakugan/images/6/64/Naga3.png Naga]] [[http://images.wikia.com/bakugan/images/0/0f/Gurifu_Kyoudai_33.jpg Dragaon]]. The list will go on forever at this rate.
** Just covering a few missed ones. There's [[http://images.wikia.com/bakugan/images/9/93/Farbros.jpg Farbros]] a mehanical dragon, then there's [[http://images.wikia.com/bakugan/images/9/9d/Krealms2.JPG Krakenoid]], [[http://images.wikia.com/bakugan/images/1/1a/Pashibaru.PNG Percival]], [[http://images.wikia.com/bakugan/images/4/43/Bakugan-battle-brawlers-20090609061512480.jpg Hydranoid]] (all three of his forms) and [[http://images.wikia.com/bakugan/images/2/2c/Apollonir_Bakugan_form.png Appolonir]], the video game gives us [[http://images.wikia.com/bakugan/images/e/e4/Bakugan_Wii_screenshot_210--screenshot.jpg Leonidas]].
* OutOfCharacterAlert: Taken UpToEleven when, of all things, [[spoiler:what ticked [[LivingLieDetector Shun]] off to Hal-G impersonating [[TheJeeves Kato]] is him ''once'' referring to Marucho by his name alone, as opposed to "''[[InsistentTerminology Master]]'' Marucho.]]"
* PowerLevels: Have been escalating. Brawlers can now take their opponent's Bakugan if their Bakugan's power level exceeds the opponent's by 500, and this happens regularly--as do power levels nearing 2000. Also, in episode 9 of ''New Vestroia'', Lync says that a Bakugan can't move if its power level drops below 300. In ''Battle Brawlers'', Bakugan with a natural power level below 300 were commonplace.
** MagicAIsMagicA: In episode 15, this new "rule" is violated. Repeatedly.
*** Heck, the power levels in the actual game have been increasing as well, though at a slower pace. 450 to 500 Gs used to be powerful, but now we have Bakugan with 1000 Gs. Luckily enough, 1000 is as far as it goes...for now.
** The highest so far has been Drago with 3150 Gs. Granted, this was seen as far too much in-universe, and he was in danger of ''exploding'', but...
** Power levels vanished about halfway through ''Gundalian Invaders'' and haven't returned in ''Mechtanium Surge''.
* NotQuiteDead: [[spoiler:Emperor Barodius and Dharak weren't vaporised, but instead sealed in another dimension by Code Eve, transforming them into Mag Mel and Razenoid.]]

* PaperThinDisguise: used to incredible extremes.
** Spectra and Gus make a grand arrival on Earth walking out of a Ferris Wheel. A few days later, Gus is able to walk around unnoticed by the Brawlers simply by taking his coat off. Later on, he sneaks into the throne room, wearing [[DisguisedInDrag a cocktail dress and a ponytail]].
** Talkng of Spectra, Mira doesn't recognise him as [[spoiler: her brother]] until he takes his mask off, despite them having the same voice and face.
** No-one recognises Anubias and Sellon's alien forms until they transform right in front of them.
** Invoked by Wiseman, who [[spoiler: models his human form off Gunz Lazar in a spandex costume]] to frame him, but many viewers can tell them apart from their hair colour.
** The top Brawlers in season 1 went to the same shop selling black cloaks as Anime/YugiOhGX. Julie knows two of them personally, but doesn't recognise them until the take the cloaks off.
* PowerTrio: Through three series, we've had three different Haos, Darkus, and Subterra brawlers...but [[TheHero Dan]], [[TheLancer Shun]], and [[TheSmartGuy Marucho]] have been there for all four seasons.
%%* ProperLady: Alice
* PutOnABus:
** Joe in ''New Vestroia'', while [[PlayingWithATrope played with]] in ''Gundalian Invaders'' as [[spoiler: Dan and Julie took a bus away from Runo and Alice.]]
** The [[http://www.bakugan.com official website]] has also removed most of the content regarding ''Battle Brawlers'' in favor of ''New Vestroia'' material...Not exactly sure how they're going to bring the suspense about Shun's return, which hasn't actually aired in the US yet...
** Also Preyas Angelo/Preyas Diablo. He disappears until Mechtavius Destroyer wages an attack on New Vestroia... and gets a painfully brief cameo before [[spoiler: he has a DisneyDeath.]]
** By how the website's now been Gundalian-ified, things aren't looking too good for the New Vestroia characters...Mira, Ace, and Baron are replaced by Jake, Ren, and Fabia, respectively by Bakugan type.
** So far in Gundalia, this seems to have happened to Preyas, Elfin, and Ingram.
*** In short, if your Brawler or Bakugan is Darkus, Subterra or Haos, you're screwed.
** ''All of the Trap Bakugan''.
** TheBusCameBack for most of them in the fourth season, including Preyas (who is training an apprentice in Vestoria) and most of the ''Gundalian Invaders'' characters due to Marucho sending out a GondorCallsForAid and Gundalia being Mag Mel's first target after being freed. Many other Bakugan make a return in "Mechtanium Surge," Tigerra showing up once, and then a large number making last stand against Mechtavius Destroyer in the BadFuture, including Gorem, Preyas Angelo/Diablo, Skyress, Ingram, Taylean, Hydranoid, Tristar, Tigerra (again), Preyas, and Elfin. The Vestal-native Bakugan do not return.
* QuicklyDemotedWoman: Used to be gender equal. Not. Anymore.
* RealLifeWritesThePlot: Part of the reason Skyress didn't stick around was because the person who provided voice work for her couldn't return, but a deal was made for Skyress to have a goodbye episode.
* TheReasonYouSuckSpeech: [[spoiler:Genesis Dragonoid (through Dragonoid Destroyer) to Mechtavius Destroyer.]] %%Can you add Drago's quote, please?
* RedemptionEarnsLife: It says something when the ''only'' survivors of the Twelve Orders were the ones who turned good.
%%* RedemptionEqualsDeath: [[spoiler: More or less the end result of Volt and Lync's [[HeelFaceTurn Heel Face Turns]].]]
%%** [[spoiler:And later Prince Hydron as well.]]
%%** [[spoiler:Possibly Professor Worton and Betradron.]]
* ReflectionlessUselessEyes: The Vestals are different from humans by their eyes, because they have a colored pupil and no shine.
* ReverseMole: [[spoiler:Mira makes an apparent FaceHeelTurn...and proceeds to completely sabotage the Vexos' plans.]]
* RightForTheWrongReasons: In one episode, Runo thinks that Alice is responsible for Masquerade knowing where they go, despite not telling anyone. While [[spoiler: she is right]], She thinks Alice is directly telling the guy, when in fact, the two are [[spoiler: One and the same]].
* SayMyName:
** Joe shouts [[spoiler:Wavern's name when she is destroyed to release the Infinity Core within her.]]
** Dan shouts Drago's name in every single battle. [[DrinkingGame Take a sip everytime]].
* ScrewTheRulesIHavePlot: The exact rules of the game are never quite made clear, but it's ''still'' obvious that what Dan and Drago are doing in the second episode of ''New Vestroia'' is circumventing them.
%%* ScreamsLikeALittleGirl: Jake.
* ScreensAreCameras: When Dan and his friends video chat over the internet, there can't be seen any camera.
* SealedEvilInACan: The season 4 BigBad, Mag Mel, is presently sealed away in another dimmension along with his Bakugan Razenoid. Reason for their imprisonment? '''Genocide.'''
* SeriousBusiness: Justified, as Bakugan can do [[TheGamePlaysYou a lot of damage]].
-->'''Reporter:''' Tell us about what really inspires you the most?
-->'''Girls:''' Bakugan!
* SequelHook: At the end of ''New Vestroia'', [[spoiler:The last thing Prof. Clay sees before the ship blows is footage of Bakugan at war with each other, setting the stage for]] ''[[spoiler:Gundalian Invaders]]''.
* SetRightWhatOnceWentWrong: [[spoiler: Mechravius Destroyer obliterates Bakugan City and everyone in it, as well as succeeds in Bakugan genocide, so Dan and the Brawlers go back in time to stop him. However, it does not save the fallen Nonets, while the last two left alive perform a HeroicSacrifice to make this happen.]]
* SheIsNotMyGirlfriend: Dan tries to deny that Runo isn't his girlfriend even in ''New Vestroia'', where they are already an OfficialCouple since the finale of the first series. Of course, he doesn't fool anyone.
* TheShortGuyWithGlasses: Marucho, who remains short throughout the series, [[OlderThanTheyLook despite aging up]]. Take a guess who is TheSmartGuy.
* ShoutOut: Amazon from the newest series seems to have some homages to ''Series/KamenRiderAmazon'', including his pose and dorsal spines flexing when preparing his special moves. He even does the "'''AAAAAAA-MAAAAAA-ZOOOONNNN!'''" when preparing his attacks.
* SixthRanger:
** Joe in terms of when he joins the show, and Alice in terms of when she starts brawling, in ''Battle Brawlers''. Shun in ''New Vestroia'', and no, that doesn't need a spoiler.
** What ''does'' need a spoiler is the ''other'' SixthRanger: [[spoiler:Spectra, a.k.a. Keith, Mira's brother]].
** [[spoiler: Fabia]] starts out as this, but then [[spoiler: Ren]] becomes this after his HeelFaceTurn.
* SlasherSmile:
** [[spoiler: When Alice remembers a flashback of Masquerade battling people and sending their Bakugan to the Doom Dimension, she freaks out immensely when the camera pans to his face pulling this smile, phasing partially through his mask to show it's ''her eyes'']]. That moment also counts as a WhatHaveIDone?
** [[spoiler:Brainwashed Jake]] indulges in these, as do many others.
* TheSmurfettePrinciple: Mira in ''New Vestroia'' and Fabia in ''Gundalian Invaders'' are the only girls who are part of the main cast.
* SortingAlgorithmOfEvil: While mostly completely unconnected, each season's BigBad is a great deal stronger than the previous one. Their actions also get progressively more evil as they go along as well. Case in point, while Zenoheld ''attempted'' genocide but failed, the season four BigBad Mag Mel is said to have been imprisoned for actually committing it.
* SpellMyNameWithAnS: Dan "Kuso". Actually, his surname is spelled "Kuusou".
* SpinOff: TMS decided not to Dub Mechtanium Surge in Japanese and instead, do an anime adaptation of the Bakutech! Bakugan Manga, starting again from scratch and rebooting the whole franchise. This however, displeases a lot of Japanese fans.
** Though this is not counted, {{Anime/Zoobles}} is also considered a Spin-off to the Bakugan Toyline since they both got similar concepts of Spherical Toys transforming into figures, except that Zoobles transform using magnetic holders called Happitats, much like the Gate Cards. But when is Bakugan is a TabletopGame, Zoobles are more of toys for girls. It gets even more HilariousInHindsight when the Zooble toys can be activated using Magnetic Recipe cards, more of a ShoutOut to the Bakugan's way of activating a Bakugan using a Magnetic Gate Card. Of course, both toys were distributed in Japan by the same company, Sega Toys.
* [[SpoilerOpening Spoiler Ending]]: The closing credits for Gundalian Invaders lists characters who ''haven't even been mentioned yet'' from the first episode.
* TheStarscream: Spectra and Mylene from ''New Vestroia''; Kazarina from ''Gundalian Invaders'' [[spoiler:, although she was ultimately loyal to Emperor Barodius.]]
* {{Stripperiffic}}: Julie wears a crop top and short shorts with most of her outfits.
* SwordFight:
** While the Bakugan do most of the combat, Dan has gotten into a couple of energy sword duels over the course of the series.
** Kazarina and [[spoiler: Nurzak]] get one, too.
* TimeSkip:
** The ending of the finale of ''Battle Brawlers'' skips ahead a couple of years, putting it shortly before the start of ''New Vestroia''.
** And there's a six month skip between seasons of ''New Vestroia''. And yet, with all these skips, Marucho doesn't grow one inch. His hair grew at least.
%%* TomboyAndGirlyGirl: Runo and Julie.
%%* TotallyRadical: Akwimos, with the slightest hint of JiveTurkey.
* TogetherInDeath: Shadow And Mylene, see YouAreWorthHell entry below.
* TransformationIsAFreeAction: Played with the second arc of ''Mechtanium Surge''. Wiseman had a tendency to not let the good guys' Bakugan combine, and would just respond to this attempt with an attack, though in "Jump to Victory" that attack took awhile to rear up so it really didn't make as much sense. In "Enemy Allies", Mechtavius Destroyer attacks ''Dan'' as he is getting ready to bring out Dragonoid Destroyer, and in "Evil Arrival" he attacks Gunz before he gets to finish saying "Bakugan Brawl". Most notably, in "Evil vs. Evil", he doesn't let Betadron, Kodokor, and Mutabrid combine, and keeps slapping Mutabrid around, but no matter how much, he insists on combining and eventually dies. That said, TalkingIsAFreeAction is still in play.
** There actually was one time that TalkingIsAFreeAction was not in play, during the final battle, when Dan was confused as to why Dragonoid Destroyer was only using 90% of his power. This was done for surprise effect later on.
* {{Tsundere}}: Runo and Julie ''both'' fit this trope. Come to think of it, Billy and Julie have BelligerentSexualTension as well, except Billy's not part of the main cast so we don't get to see the extended WillTheyOrWontThey like we do with Dan and Runo.
* VictoriousChildhoodFriend: The two {{Official Couple}}s in the series consist of characters who met each other when they were children. The difference is that Billy and Julie are known to have been friends for quite some time, while Runo met Dan only once when they were playing in the park and didn't realise the boy who was annoying her that day was actually Dan.
* VoiceOfTheLegion: Mag Mel's followers have this in their true forms.
%%* WalkOnWater: Played straight in Gundalian Invaders. ''TWICE''.
%%* [[WarriorPoet Warrior Thespian]]: Jesse.
* WaterIsDry: When Dan [[http://www.youtube.com/watch?v=l-bvfUivhvU&feature=related#t=4m20s runs through the river]] to retrieve Drago in ''Dan and Drago''. In the ''rain''.
* WellDoneSonGuy: Hydron. [[spoiler:When he realizes his father will never give him that approval, he does a HeelFaceTurn.]]
%%* TheWorfEffect: Aranaut's been hit with this big time.
* YouAreWorthHell: [[spoiler:Shadow has a clear chance to survive the NegativeSpaceWedgie, but opted to die with Mylene anyway,]] ([[ShipTease he thinks it'll be interesting]]).
* YouGottaHaveBlueHair:
** Runo and her mother both have blue hair, and supporting characters Jenny and Jewles have purple and green hair, respectively.
** In ''New Vestroia'', Baron has purple hair.
** The Vestals have quite a habit of falling under this trope. The only ones with real-world hair colors are carrot-top Mira and blonde Spectra [[spoiler:and it turns out they're siblings.]]
** In ''Gundalian Invaders'' Fabia has dark blue hair, though Dan refers to her as a brunette.
*** Are you sure he didn't say [[YouGottaHaveBlueHair Bluenette?]]
* ZettaiRyouiki:
** Runo is Grade S in ''New Vestroia'', having had the other two components since ''Battle Brawlers'' but only reaching Grade C throughout that series. Unfortunately, [[DemotedToExtra Runo is hardly even]] ''[[DemotedToExtra in New Vestroia.]]''
** Mira also has at least Grade B...[[FashionableAsymmetry on the right leg, anyway.]]
