The Core Members
In General
- Badass Crew: Definitely. As the core of a team fighting the antagonistic forces to Save Both Worlds. Dan is the most powerful brawler on Earth, Shun is equally powerful and he's in addition a skilled ninja and Marucho is The Team Benefactor of the group and a Badass Bookworm.
- Chromatic Arrangement: Dan, Shun and Marucho wear respectively red, green and blue representing Pyrus (Fire), Ventus (Ventus) and Aquos (Water). Subverted in Season 1 where Shun wore a purple outfit instead of a green one.
- Four-Temperament Ensemble: The three guys plus Drago are this.
- Dan is choleric - passionate, strong-willed, slighty arrogant
- Drago is snguine - feisty, leader, idealist
- Marucho is melancholic - sensitive, sometimes insecure, analytical
- Shun is phlegmatic - calm, introverted, discreet
- Freudian Trio: Dan is implusive and hot-headed representing The Id, Shun is quiet and laid-back as The Superego and cheerful but tactical Marucho is The Ego.
- Power Trio: They are the main heroes of the show, being the only consistent members of the team across all four seasons.
- Three Plus Two: Or rather Three plus three. After the first season, they're generally joined by three other members to complete the element hexagram (with Subterra, Haos and Darkus attributes). Averted in the second arc of Mechtanium Surge, where they instead each get a secondary partner Bakugan (two in Shun's case) that belongs to one of the other three attributes and use two attributes instead of just one, with Dan using Pyrus and Haos, Shun using Ventus and Darkus, and Marucho using Aquos and Subterra.
Danma "Dan" Kuso
Dan Kuso
Dan's appearance during the first fourteen episodes of Gundalian Invaders
Debuted In: Battle BrawlersDanma "Dan" Kuso is the main protagonist of the series and the boisterous and fearless leader of the Bakugan Battle Brawlers.
Dan is a boy who really loves Bakugan, but gets frustrated easily. His greatest ambition is to become the strongest brawler as much as possible, which is what he attains at the last episode of the first season. He tends to act rash and impulsive which often leads him to trouble.
He is very eager for a brawl, thinking he can take on anyone which causes him to complain a lot when he has to wait around in hiding, as shown in the first and second season. By the third season, Dan has outgrown that habit as he was telling Jake to help rebuild the second shield generator after they had a successful victory over the Gundalians. His gutsy hands on approach and bottomless courage has earned him powerful allies in the Vestals, the Castle Knights, and every brawler on his planet looks up to him.
He first lived in Wardington for the first two seasons with his friends Runo Misaki, Marucho Marukura and Shun Kazami. He moved to Bayview in Bakugan: Gundalian Invaders, and somehow Julie became his neighbor. In Bayview, he made friends with a boy named Jake Vallory. He was the number 1 Brawler in Bakugan Interspace until he was "defeated" by Anubias (Dan was actually disqualified in the brawl).
By the end of the series, Dan is considered the strongest brawler in the universe and holds the title of #1 as he goes on another journey with his best friend Drago.
- Abandoned Catchphrase: It didn't stick but him and Baron definitely loved saying "Get Psyched! Get Psyched! Get Psyched!"
- The Ace: He gradually grows into this with Drago during each season. Shun was a much better brawler than Dan during the first season but Dan's skills as a brawler continued to sky rocket until near the end of Season 1 where he became the best brawler of the team and is now usually the one who has to save the day when his friends are faced with an enemy they cant handle.
- Always Someone Better: Shun was this to him during the early stages of the series. Shun was not only a better Brawler than he was, he was calmer, wiser, and more popular than Dan was among his peers (probably not on Dan's mind but it counts). Eventually, Dan begins to grow in spades and then finally surpasses Shun, promptly switching the roles between them.
- Badass Adorable: You can't deny it.
- Badass Normal: As far as we know, Dan is a normal human being. Yup, a normal human who when motivated enough can run so fast that he blitzes over water. Not only that, he can run up a moving dragon and aim well enough to throw a spear directly into its chest. At least with Shun it's justified since he's a ninja in training, but with Dan he's supposed to be a normal kid and yet look at his feats!
- Bash Brothers: With Shun. He then eventually becomes this with Spectra during the 2nd Season.
- Berserk Button: Suspecting that one of his closest friends is a "deserter" can really set him off, as Ace found out.Dan: WE HAVE TO GO LOOK FOR MARUCHO!
- Blood Knight: As Spectra puts it:Spectra: Oh, that Kuso loves a fight!
- Book Dumb: Like any typical shōnen protagonist, he gets horrible grades and focuses his time more on games than actually studying.
- Brainwashed and Crazy: During Season 4, Mag Mel and Razenoid end up controlling Dan's mind through Drago and is a major part of the reason why Dan loses control of himself during a brawl in that Season. It gets too bad that Dan begins to endanger the safety of kids watching the battles and he leaves the Brawlers because of it, hoping to find a way to control that power.
- Character Development: At the start of the series, Dan was brash, hot-headed, aggressive, and never planned his next move ahead. He truly believed that power was all that was needed to win a Bakugan battle. After he meets Drago and goes through several battles, Dan realizes that strategy plays a giant role in Bakugan and opts himself to plan ahead. Along with his skills as a brawler, Dan develops as a human being over the course of the series and becomes much more humble, less immature, and thinks his decisions through during the later seasons.
- Chick Magnet: Yup. Runo is quite obviously in love with him (and they go on a date in finale), Julie had a huge crush on him during the beginning of the series, Alice (and Julie) mentioned she wanted to give Dan a hug for how brave he was, Mira was definitely feeling him during New Vestoria, and Fabia had a crush on him as well. The only main girl in the series that never shows romantic interest in him is Paige.
- Childhood Friends: With Runo and Shun. He met the former when he was a kid once but never saw her again while he has known the latter since they were small boys.
- The Chosen One: He was destined to be Drago's partner, automatically making him this.
- Determinator: If his battle with Masquerade and Spectra is any indication, the boy just doesn't know how to stay down.
- Dub Name Change: In the English version, his name was changed into "Daniel". Makes sense considering Dan is the shortened version of Daniel in the west.
- Even the Guys Want Him: Spectra/Keith's obsession towards Dan.
- Goggles Do Nothing: He has a pair on his head, but outside of one instance in season one, they're just for show.
- Heroic BSoD: Too many times during the series to count, but most prominently when Drago was defeated by Masquerade and sent to the Doom Dimension and when he lost to Spectra and Drago was taken as were the agreements of the match.
- Heterosexual Life-Partners: With Shun and Marucho, to a lesser extent.
- Hot-Blooded: One of his signature traits that align with his Bakugan attribute.
- Iconic Item: Only Battle Brawlers wear fingerless gloves.
- Idiot Hero: Not as much as you'd expect but still easily one of the dumbest characters of the cast. It comes with being the hero of a Shonen anime.
- It's All About Me: Had this attitude in Season 1 and the first half of Season 4. While Season 1 was justified as Dan was only just a stubborn 12-year-old rookie who bit off more than he could chew, Season 4 made little to no sense as Dan's growth was halted and his personality reversed, going from a caring and understanding leader to a reclusive jerk that brushed aside advice from two of his closest friends. In both cases, he did get better.
- This gets a focus in Season 1 of the Japanese dub, where his lack of understanding and care of his friend's feelings has caused at least three different fallouts to almost happen. Part of his Character Development is learning to listen to others and to be more mindful.
- Jerk with a Heart of Gold: His jerkish tendencies are apparent during Season 1 and he learns to become a better friend. During Season 2, he becomes slightly less jerkish but still shows shades of this towards people he doesn't like. In Season 3, Dan has mellowed out considerably and only acts like a jerk towards those who are evil. Season 4, however, is where this goes out of hand as Dan begins acting out much more than he did as a kid and begins treating his closest friends badly, mainly ignoring them and even breaking the promise he made to tell them about Drago's problems. He gets better when he realizes near the end how selfish and how much of an idiot he was being.
- The Leader: Becomes the official leader of the brawlers in the middle of Season 1 and remains the leader all the way up until Season 4 where he leaves his position and Shun takes charge. He regains his status as leader at the end of Season 4 and it stays with him.
- Mindlink Mates: A non-romantic and incredibly dark version.After Drago evolve into Titanium Dragonoid, he suddenly has Psychic Link with series Big Bad, Mag Mel. As the result, both of them able to sense each other through telepathy, and Mag Mel constantly Mind Rape Dan by using this.
- Mr. Fanservice: Constantly has his outfits torn to shreds whenever he battles a serious opponent, most notably with Masquerade.
- Out-of-Character Moment: His entire character in Season 4 really doesn't act like the Dan that we all know he is. Ignoring his friends, keeping everything to himself, refusing to stop allowing Drago to brawl despite knowing that brawling is the cause of the dilemma's happening? Let's not forget Dan ignoring his adoring fans, that really doesn't sound like Dan at all. Spectra even lampshades this when he meets Dan in that season, showing disappointment as his "new" attitude and has stated that Dan has lost his spark. Thankfully, his character is restored to how he was supposed to be during Part 2 of Season 4, becoming the person he was meant to become.
- Playing with Fire: Like Dan has stated, he's a Pyrus Brawler. His use of Bakugan isn't completely limited to that attribute but its his main thing.
- Say My Name:Dan: "DRAGOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!"
- She Is Not My Girlfriend: Tried to invoke this with Runo during New Vestroia but everyone doesn't believe him. I mean, really Dan, who are you trying to convince?Shun & Drago: She's not?
- Ship Tease: With Runo and arguably with Mira and Fabia. These shipping moments happen less and less as the series stops having girl characters being a prominent part of the series.
- Stock Shōnen Hero: Dan has the spiky hair, red colours, determined attitude, Book Dumb aspects, Hot-Blooded nature, and wants To Be a Master.
- To Be a Master: His dream was to be the best brawler in the entire world. He obtains that dream and in the process, gains a new one which is saving the world and protecting whats important to him.
- Totally Radical: In the first few episodes of Battle Brawlers.
- Took a Level in Jerkass: Season 4 has Dan becoming more selfish and ignorant. He deliberately refuses to stop using Drago in their battles and is always hostile towards his friends, despite his dark side making him crazy. When he returns from training, he expected everyone to praise him and listen to him and him alone. However, he got more insane when everyone who once looked up to him branded him a hated outcast. His worst act is, after Marucho honestly calls him a "risk", Dan grabbed him by the neck while screaming in his face.
- Undying Loyalty: When Dan had lost his official battle with Masquerade and ended up getting Drago banished to the Doom Dimension (which everyone knew was the equivalent to hell for Bakugan), Dan ran after him without a moment's hesitation and jumped in with him. That's right, Dan was willing to give up his life on Earth just to remain by Drago's side. If the kid's got one thing, it's loyalty.
- Vitriolic Best Buds: With Shun.
- World's Strongest Man: Considered the best Brawler on Earth and is always Ranked # 1 on the boards. There are very few Brawlers around that can match him, especially considering the frequent evolution his partner Bakugan go through. Even though he lost his title to Anubius during his match, it was mainly because Drago was busy trying to contain his power and not endanger the safety of the fans watching. If it had been a fair fight, he and Drago would have easily won the match.
Choji "Marucho" Marukura
Marucho Marukura
Marucho's appearance during the first fourteen episodes of Gundalian Invaders
Debuted In: Battle BrawlersVoiced by: Ryō Hirohashi (JP), Joanne Vannicola (EN), Dulce Guerrero (LA SP)
For an eleven-year-old, Marucho is wise beyond his years. Studious, he studies the strategy of Bakugan as well as being a bit of a walking encyclopedia. Marucho is the only son of a millionaire. In the Bakugan battles, Marucho devises strategy based on in-depth data analysis but sometimes misjudges his spur-of-the-moment decisions based only on data.
He is a wealthy, generous boy who specializes in Aquos. He is the brain of the Brawlers, a real walking encyclopedia. He loves to play Bakugan and work on strategies. He used to be extremely obedient to his parents out of fear, but that changed when he joined the Brawlers; however, he is still very obedient. He now has no regrets for the past, realizing that he only wanted to make his parents happy. Marucho has a butler named Kato.
As a sidekick to Dan, Marucho helps work out which Bakugan would be best to pit against one's opponent. He worries about all of the Brawlers, but especially Dan. Marucho is a master of combination play, and uses water attributes in battle.
- Alliterative Name: Marucho Marukura.
- Averted by his real name; see Only Known by Their Nickname below.
- Ambiguously Bi: Marucho is clearly interested in some girls, especially Idol Singer Jewels (given he faints when she kisses him after the brawl against Naga' s Warriors near the end of the original) and Alice makes him blush at one point, but he also gets
Ho Yay with Ren, especially this scene
◊ where he actively puts his hand on his crotch. - Affectionate Parody:
- Elfin of Sailor Moon.
- Minx Elfin is just plain Baku Moon.
- Battle Couple: Elfin and Preyas.
- Badass Adorable: His size, big eyes, and voice! It says it all!
- Blue Means Smart One: Marucho is the smart one among the brawlers, as he's very logical and he knows a lot about the rules of the game. He uses Aquos Bakugan, which are blue in color, and his outfits always incorporate blue.
- Character Catchphrase:Akwimos: Cool is the rule dude!
- Formal Characters Use Keigo: Befitting of a young master, Marucho speaks very formally and respectfully in the Japanese dub, to the point of even referring to his friends with the honorific -san.
- Good Angel, Bad Angel: Angelo and Diablo.
- Idiot Ball: Marucho's loss in episode 2 of Gundalian Invaders involves him not preparing for a strategy that was just used on him.
- Idiot Hair: Has the worst hairdo of the heroes.
- I Hate Past Me: He used to hate his old self due to being very obedient to his parents and unable to make decisions on his own, something which changes after he becomes a battle brawler. However, he learns to accept his past after Preyas makes him realize that he chose to listen to his parents because he wanted to make them happy.
- Hair Antennae: His Idiot Hair shape resemble with fish tail, represent his main elements.
- The Heart: Marucho as of Gundalian Invaders, cemented in Mechtanium Surge.
- Heterosexual Life-Partners: With Ren in Gundalian Invaders.
- Making a Splash: Most of his Bakugan are Aquos Bakugan with the attribute of water.
- The Smart Guy: His main role at Battle Brawler team
- The Strategist: As The Smart Guy of his team, he often think about the strategist to winning. After Alice left in New Vestroia, he become the only strategist in Battle Brawlter team.
- Put on a Bus: Preyas, Angelo, Diablo and Elfin. Though The Bus Came Back briefly for Preyas in both New Vestroia and Mechtanium Surge.
- Sailor Senshi Send-Up: Elfin. She visually evokes Usagi in appearance (she is blonde, wears a hairstyle resembling a frog head, but whose "eyes" correspond to Usagi's buns, and with long finlike appendages that correspond to Usagi's long pigtails). She has a long, magical girl-like Transformation Sequence, and strikes the In the Name of the Moon pose.Elfin: Sun, wind and rain combined! In the Name of the Moon! Behold Aquos/Ventus/Darkus (depending on her chosen attribute) Elfin!
- Older Than They Look: Marucho is seventeen by the end of the series. He's still at Dan's waist.
- Only Known by Their Nickname: You didn't know his name was Choji till now.
- The Quiet One: Preyas, more or less.
- Took a Level in Badass: Like Shun, Mechtanium Surge has been quite kind to him in the badass department.
Shun Kazami
Shun Kazami
Shun's appearance during the first fourteen episodes of Gundalian Invaders
Debuted In: Battle BrawlersVoiced by: Chihiro Suzuki (JP), Zachary Bennett (EN), Carlos Hernández (LA SP)
The strong silent type. Along with Dan, Shun co-created the rules and regulations of Bakugan and is a master of the game. Shun is a loner, a boy of very few words, yet is willing to help his friends at every turn. He approaches the game like a Ninja warrior, very calculating. Shun uses the wind attributes in battle. Many fans like to pair him with Alice, although throughout the series he has shown tiny interest in Julie Makimoto.
Shun is one of the calmest brawlers in the series. He rarely gets flustered or annoyed, and even when he is annoyed, he maintains a cool voice (although he voices his displeasure). Shun is a lone wolf and always focuses in battles.
Shun Kazami lives in the province, and is a Ventus attribute player. He is also an aspiring ninja, receiving training from his grandfather. He is a loner, yet is willing to help his friends at all costs. Together with Dan Kuso, his best friend and childhood friend, he invented the gameplay for Bakugan. He had been the first ranked battler until Masquerade and his minions dominated the rankings, and because he quit playing Bakugan due to grief after his mother's death (His grandfather didn't let him play in the dub), ending up in 6th place. After defeating Komba, he ends up fifth. Shun is currently in 3rd place.
Shun reappears in Bakugan: Mechtanium Surge with Ventus Taylean. Shun is now 4th strongest Brawler in Bakugan Interspace, behind Dan, Anubias, and Sellon, respectively. However, this is due to him not battling as much as he used to - due to his ninja training. He is starting to get suspicious of what Dan and Drago are doing. Later, he is seen commenting on whether Drago and Zenthon are connecting - due to the timing.
- Abusive Parents: In the dub, at least. Shun's grandfather is adamant that he will become a ninja, and even declared he will make him focus on his training just seconds after his mother fell into a coma. He brutally isolates Shun from his friends, and is incredibly hostile to anyone not named Shun. You can hardly blame Shun for having such a hard time trying to come back into Bakugan in this version. Though as a result of Dub Induced Plothole, he has, though rarely, shown a more compassionate side to him, such as when he forced Shun to show him around town and spent time with his grandson. Generally, though he rarely shows it, he cares for the well being of his grandson perhaps more than him becoming a ninja champion.
- The Ace: He's one of the best brawlers at the beginning of the series and even after Dan becomes stronger than him, he's got still a fairly high rank. He's also a quite proficient ninja.
- Adaptational Backstory Change: Out of all of the Battle Brawlers, Shun's the only one to have a somewhat major deviation from his original backstory due to changes to both his mother and grandfather. For reference, originally, Shiori had passed away while Shun's grandfather had no ill will, simply explaining the situation about Skyress and Shiori to Shun, setting up Shun's story and development to revolve around his grief over his mother's passing. Meanwhile in the dub, Shiori simply slipped into a coma in the dub rather than passing away, and his grandfather wanted to force Shun to focus on his ninja training thus causing Shun to greatly resent him.
- Badass Longcoat: In New Vestroia he wears a loooong vest that is just as awesome.
- Blow You Away: Most of his Bakugan have the Ventus attribute.
- Broken Bird: Losing his mother caused him to shut out essentially everyone in his life except for Skyress. With the help of his friends, he gets better.
- Childhood Friends: With Dan, who is his best friend.
- Conveniently an Orphan: Shun doesn’t have a father, AND his mother fell terminally ill and eventually died, leaving just his grandfather to look after him.
- Daddy Issues: More like granddaddy issues but in the dub, it is made clear that Shun deeply resents his grandfather for trying to turn him into a ninja so soon after his mother fell into a coma (In the dub only, the original had his mom dying). The two make up by the end of the series as part of their Character Development.
- Disappeared Dad: His father is never mentioned or made appearance in series.It's never know whether he and Shiori are divorced or already passed away.
- Dub Personality Change: Thanks to his Adaptational Backstory Change, instead of having given up on Bakugan out of grief, his grandfather basically forced Shun to stop seeing his friends and playing Bakugan which in turn makes him a much more brooding and sardonic lone wolf-type of character as opposed to the original Japanese dub where he's shown to be a rather gentle and quiet person dealing with grief.
- Expository Hairstyle Change: His hair slowly grows back in Mechtanium Surge.
- Establishing Character Moment: His first appearance has him firmly reject Runo and Marucho's appeal to join them, only for Skyress to coax him out of it, before being adamant they have to beat him. Despite clearly not having played the game for awhile, Shun manages to defeat two opponents very easily, and even when he is given a temporary loss by Preyas's attribute change ability, he takes it in stride, establishing himself as a very formidable player.
- The Lancer: Shun, co-lancer with Runo (at least in the first season).
- Heterosexual Life-Partners: With Dan, who also his Childhood Friends.
- Hidden Depths : His ability to discern people and their motives makes him into a Living Lie Detector.
- Foil: To Dan, who is more hot-headed, loud and arrogant hero than him
- Important Haircut: Between Battle Brawlers and New Vestroia, he cuts his long ponytail and his hair is reduced to neck-length.
- Missing Mom: His ill mother died in the hospital after giving Skyress to him, who becomes a Tragic Keepsake after that. The event however caused Shun to quit playing Bakugan out of grief until the other Battle Brawlers seeked him out for help against Masquerade. The English dub, however, changed it to look like she just fell into a coma, although the beep indicating a flatline ruins that explanation.
- Moving Beyond Bereavement: In the Doom Dimension, Shun's test is to accept the death of his mother; as such, his rival is his mother as a little girl.
- Not So Stoic: Despite being introduced as the stoic ninja, Shun's cool façade is ultimately just an act born out of the grief of losing his mother (or in the dub's case, his grandfather isolating him). It breaks when his mother is on her deathbed.
- Happens again in Season 4 when trying to talk some sense into Dan.
- The Quiet One: He lacks in speech, but he makes up for it with skill.
- Raised by Grandparents: His grandfather is looking after him since the disappearance/presumed death of his father and the coma/actual death of his mother.
- Red Oni, Blue Oni: The blue to Dan's red.
- The Rival: To Dan at first, though it later becomes a more Friendly Rivalry.
- Secretly Selfish: When his mother was on her deathbed, he challenged Dan to a battle with the intent of making it last forever so his mother would remain alive.
- Ship Tease: With Alice in Battle Brawlers and Fabia in Gundalian Invaders.
- Sugar-and-Ice Personality: Shun is very quiet to the point of being seen as cold and distant at times, but he's in fact a very kind person that cares deeply for his friends.
- Stock Shōnen Rival: While he is friendlier than the norm, Shun still fits. He's strong, a Tall, Dark, and Handsome rival towards Dan who enjoys being alone.
- Took a Level in Badass: In Mechtanium Surge, he becomes the leader of the Brawlers when Dan takes off and takes his fighting skills up a notch. Taylean even becomes strong enough to create a Mechtogan, something only the Big Bad Mag Mel and Drago were previously able to doing (and Mag Mel was impressed when Drago did it).
- Used to Be a Sweet Kid: While downplayed as he's still a kind character, flashbacks during the first season show that he was much more outgoing, energetic, and social prior to his mother's death.
- Vitriolic Best Buds: With Dan.
- You Are Not Alone: Arguably the biggest part of his Character Development (in the Japanese dub) is him realizing that he isn't alone and that he doesn't have to deal with his grief alone.
Affiliated Bakugan
Pyrus Dragonoid / "Drago"
Drago
Drago as a Pyrus Helix Dragonoid
Debuted In: Battle BrawlersVoiced by: Keiji Fujiwara (JP), Jason Deline (EN), Javier Rivero (LA SP)
Drago (original version: Nova Dragon) is Dan Kuso's Guardian Bakugan and the Bakugan main protagonist of the Bakugan Battle Brawlers anime series. He serves as both a battle partner, a guardian, and source of wisdom. Although he is impatient and is a pacifist, he wants to help Dan protect Earth and Vestroia.
He is the direct descendant of the original Dragonoid, one of the first two Bakugan ever created. He is one of the most powerful species living in Vestroia, able to infinitely evolve on his own. In battle, his power is to radiate intense heat from his body, dissolving everything around him.
Drago's personality resembles that of an honorable knight; he has a strong sense of justice, never allows anyone to get away with their evil deeds, is fully commited to the greater good, and holds high regard for honor and justice. He has, on more than one occasion, been willing to sacrifice his own life to save the lives of others, or for the greater good.
He also is shown to be rather fearless, rarely being afraid in the face of danger and rarely shows any distress or panic in any situation. While he is willing to fight to protect the innocent and for sport, he usually dislikes fighting on the spur of the moment and when it is for someone's own selfish or evil intentions, which he regards as meaningless.
- All-Loving Hero: While not at first, Drago eventually came to put the safety of the Bakugan (and humans) above his own when the possibility of both of their worlds being destroyed comes awfully close to becoming a reality.
- Ascended to a Higher Plane of Existence: He becomes part of the Perfect Core at the end of Season 1. It doesn’t last however as he gets his physical form back by the start of Season 2.
- Big Good: After season 1, he becomes the leader of all Bakugan.
- Blood Knight: Like his Brawler, Drago loves a good fight. However, he knows when to rely on strategy rather than brute force, though this later gets downplayed in later seasons.
- Brought Down to Badass: Season 2 has him being separated from the Perfect Core and regaining his physical form as Neo Dragonoid. While nowhere near as powerful as when he was Infinity Dragonoid, he's more than capable of putting up a fight against any Bakugan thrown at him.
- The Chosen One: It turns out that Drago (along with Dharak) possesses the Ultimate Warrior Gene and are direct descendants to the first two original Bakugan ever made. Because of this, both Drago and Dharak have the potential of becoming the most powerful Bakugan in existence if they are able to find their chosen partners.
- Deadpan Snarker: Definitely counts for this in the first two seasons but surprisingly tones it down by Season 3 and by Season 4, Drago has practically become Dan just in Bakugan form.
- Draconic Humanoid: After his evolution near the end of Season 2, Drago takes on the form of a humanoid dragon and gains human limbs.
- I Choose to Stay: At the end of Season 2, Drago chose to stay on Earth with Dan rather than live on New Vestroia with his brothers and sisters. It really shows how much Drago cares for Dan.
- Composite Character: Cross Dragonoid incorporates features of Apollonir's battle form onto Drago.
- Intergenerational Friendship: While Drago is stated to be young by Bakugan standards, it is made obvious that Drago is a young adult, given how much more mature he is when we first meet him. He is friends with Dan, a 12 year old boy.
- Jerk with a Heart of Gold: Despite his rough and tough exterior, Drago is actually a big softie and will do anything to protect those that he cares for.
- Face–Heel Turn: Downplayed. After Dan loses to Spectra during their brawl, Spectra takes Drago and brainwashes him into becoming an obedient slave that doesn't even recognize Dan.
- Hair-Trigger Temper: It is stated that before meeting Dan, Drago had a much more violent temper.
- Heroes' Frontier Step: While he clearly dislikes Dan initially, he tries to be friendly with Dan, indicating that despite his demeanor on the outside, he does care deeply about others.
- It is also indicated by Wavern that Drago saw her as a normal Bakugan instead of a powerless white Bakugan that was powerless, which apparently is rare among Bakugan, given that white Bakugan are frequently discriminated against.
- Heroic Sacrifice: At the end of Season 1, Drago chooses to give up his physical body to become the new core of New Vestroia so that the balance between the dimensions can be maintained. He gets better, though.
- Heroic Willpower: He is hit by the shockwave of negative energy that sent a fear ripper insane with fear, and managed to maintain not only his powers of reason, but his ability to speak.
- Heterosexual Life-Partners: With Dan.
- Hypocrite: In episode 3 of New Vestroia, he criticizes Dan when Dan is convinced that only Drago is needed, pointing out he needs backup and that there is strength in numbers. If he was so worried about numbers, he probably should have considered asking Runo, Julie, or Marucho.
- Idiot Ball: At the beginning of New Vestroia, Drago is sent to Earth to bring a human to help the Resistance liberate the Bakugan. He meets up with Dan and his friends, and promptly explain what is happening. All of the Brawlers present volunteer to help. Drago decides he only needs Dan, as he knows he can count on Dan, but does not want to put the others in harm's way. Drago worked with the other brawlers back in Season 1, and he knows they can be formidable fighters when needed, not to mention Marucho, Julie, and Runo all risked their lives for Vestroia back in Season 1, so his decision to keep them in the dark in order to avoid putting them in danger really doesn't make sense.
- Even more bizarrely, Drago decides to just tell the Brawlers to turn around, and then urges Dan to leave discreetly. He could have just told the other three that he only needed Dan, or that he could have taken all three of the other Brawlers to New Vestroia, and it certainly would have spared a lot of trouble later in the show, given how livid Runo and Julie are over convincing Dan to ditch them, and Marucho managing to sneak in to the portal.
- Mr. Exposition: While all of the main Bakugan in Season 1 do this from time to time with the humans, he does it the most often, especially in regards to the plotline and the Bakugan that debut later in the first season.
- Not in Front of the Kid: He tells this to Wavern when they reunite. He clearly is happy to see her again, but he leaves their reunion at mostly friendly banter, and while he acknowledges her pet name for him, and concedes that they are in a romantic relationship, he urges Wavern not to blatantly flirt with him in front of the Brawlers, as they are only innocent children. This has Wavern do it more to him.
- Not So Above It All: When Runo embraces Tigerrara after the previous shot hinted at a romantic moment, Drago teases Dan by saying "The ladies love the Bakugan.", knowing that Dan was expecting a romantic moment, despite Dan arguing he didn't have feelings for her, and he is clearly trying to avoid laughing when Dan responds.
- Only Sane Man: Early on in the seasons, Drago was not afraid of voicing out his disapproval of Dan's strategies and was usually the first to reprimand Dan whenever he was acting like an idiot. Later seasons, however, show that Drago has lost this aspect of his character as he follows all of Dan's ideas without question, even when its blatantly obvious that they aren't the wisest choice of action. He is also fully willing to reprimand one of his fellow Bakugan if they do something incredibly foolish or reckless.
- Physical God: His evolutions had gradually made him stronger; to the point that he had became a god-like being among other Bakugan.
- Playing with Fire: He's a Pyrus Bakugan, what'd you expect?
- Powered Armor: The Maxus Trap Bakugan can combine with him to give him this, becoming Maxus Dragonoid and again after evolving as Maxus Cross Dragonoid.
- Seen It All: There is very little that will make him visibly nervous in the show.
- Star-Crossed Lovers: With Wavern. It's a terrible shame that their love couldn't be anything more due to both of them ending up sacrificing themselves for the greater good.
- Team Dad: Acts this way towards the other Bakugan.
- Took a Level in Badass: Each and every time Drago goes through an evolution, you can bet he'll come back twice as strong as he was before; packing some sweet new ability cards.
- Tranquil Fury: He rarely shows his anger outright, with his tone and body expressions making it clear he is livid, but his voice makes it clear when he is really angry.
- Undying Loyalty: Though not at first, Drago's bond with Dan continued to grow until the point that both of them just can't function without the other.
- Vitriolic Best Buds: With Preyas. Drago clearly dislikes Preyas's comedic antics and one liners, but he is saddened when Preyas “dies” in Season 1.
- World's Strongest Man: He’s the most powerful Bakugan in existence.
- Worthy Opponent: He considers Helios this.
- You Can Talk?: He expresses surprise when Dan's mother reveals that she can hear him.
Marucho's Bakugan
Aquos Preyas
Debuted In: Battle Brawlers
Voiced by: Eiji Miyashita (JP), Shawn Meunier (EN), Rodrigo Carralero (LA SP)
- Beware the Silly Ones: As the Vexos found out, Preyas is a force to be reckoned with when pissed. He is the only one of the original six aside from Drago to score a win against their second generation of Mechanical Bakugan, and in fact beat two of them at once, one of which had previously bested Alpha Hydranoid.
- Breakout Character: Out of the six original fighting Bakugan, he got the most spotlight after Season 1 and in fact remained Marucho's partner in New Vestroia's second half, together with Elfin. Though he is absent for all of season 3, he makes several guest appearances in Mechtanium Surge, acting as the leader of the Bakugan living on New Vestroia.
- Butt-Monkey: He gets this a lot until he "evolves".
- Chuck Cunningham Syndrome: He and Elfin (and Ingram) are nowhere to be seen after the final battle of New Vestroia and no reason is ever given for their sudden absence, not even after The Bus Came Back in Mechtanium Surge.
- Deadpan Snarker: Half his jokes are this.
- Mechanically Unusual Class: He is the first of only a handful of Bakugan that can willingly change their attribute, with his usuals being Darkus and Subterra. Two of the three other ones learned it from him. And that's not even getting into how he "evolved".
- Mister Seahorse: His "evolution" basically involves him giving birth to a Bakugan who includes both Angelo and Diablo into one.
- No Celebrities Were Harmed: Often does impersonations.
- Took a Level in Badass: Notably gains the largest power boost without ever really evolving even once.
Aquos+Haos Preyas Angelo
Debuted In: Battle Brawlers- Deadpan Snarker: He introduces himself saying that he requires every second Monday off, and he's not available to do windows.
- Light Is Good: He's a Haos and the good form of Preyas's evolution.
- Mechanically Unusual Class: Preyas "evolved" by spitting out two equally powerful twin brothers who had uniquely merged Elements and shared a ball form.
Aquos+Pyrus Preyas Diablo
Debuted In: Battle Brawlers- Chuck Cunningham Syndrome: Oddly, the duo were completely absent from New Vestroia, even after Preyas returned to Marucho. Diablo (but not Angelo) returns in the final season as part of the army of past Bakugan defending New Vestroia, but is the first to die.
- Dark Is Not Evil: Downplayed as his secondary attribute is Pyrus, not Darkus. He wants to be this, but is stuck with his goody-two-shoes Haos counterpart.
- O.O.C. Is Serious Business: Is surprised when he and Angelo agree on something.
- Vitriolic Best Buds: With Angelo due to being two sides of Preyas.
Aquos Elfin
Debuted In: New Vestroia- Chuck Cunningham Syndrome: She and Preyas are nowhere to be seen after the final battle of New Vestroia and no reason is ever given for their sudden absence, not even after The Bus Came Back in Mechtanium Surge.
- Expy: Her personality and Magical Girl-esque design take clear inspiration from Sailor Moon. In addition, her Darkus form after evolving into Minx Elfin appears to be based off Tuxedo Mask.
- Mechanically Unusual Class: Like Preyas, she's able to willingly change her attribute, with her usuals being either Ventus or Darkus.
- Official Couple: With Preyas.
- The Smurfette Principle: Not only is she the only female Bakugan in the main cast of New Vestroia, she is also Marucho's only female partner, period.
- Vocal Dissonance: Elfin’s first VA made her sound like an old woman, which didn’t work with the “magical girl knock-off” characterisation they were going for.
The Other Darrin sounded a lot more fitting.
Aquos Akwimos
Debuted In: Gundalian Invaders- Borrowed Catchphrase: His catchphrase is the one thing his digital clone could say.
- Chuck Cunningham Syndrome: Averted. He’s the only one of Marucho’s partners prior to his final partner, Radizen, whose departure is both shown and explained.
Aquos Trister
Debuted In: Mechtanium Surge Part 1- Blood Knight: Constantly craves fighting.
- Chuck Cunningham Syndrome: Just like Preyas and Elfin before him, no reason is ever given for his sudden absence in the second arc of Mechtanium Surge.
- Remember the New Guy?: Unlike Marucho’s previous partners, who become his partner during their respective seasons, Trister is already Marucho’s partner at the very start of Mechtanium Surge and it isn’t revealed how they met until almost halfway through the arc.
Aquos Radizen
Debuted In: Mechtanium Surge Part 2- Remember the New Guy?: Just like Trister, he is already Marucho’s partner at the very start of the second arc of Mechtanium Surge. Unlike Trister, it is never explained how he and Marucho met.
Shun's Bakugan
Ventus Skyress
Debuted In: Battle BrawlersVoiced by: Chiharu Suzuka (JP), Barbara Budd (EN), Héctor Moreno (LA SP)
- Back from the Dead: No less than THREE times. She's died against Oberus, Hairadee, and Mechtavius Destroyer. However, given that she's based off of a phoenix, that's not surprising. (Although, she was only brought back the third time because the Brawlers went back in time to Set Right What Once Went Wrong.)
- Blow You Away: As is the case with any Ventus Bakugan.
- Deadpan Snarker: She has her moments.
- Dub Personality Change: Unlike in the English dub where Skyress essentially takes on the role of Shun's surrogate mother, in the original Japanese dub, this is not the case. While still incredibly close to Shun, and is often a voice of wisdom for him, she outright tells him that she cannot be a mother figure to him and instead acts more like a trusted confidant to him.
- The Dreaded: The tone of Marucho's voice indicates that Skyress, or at least the Skyress species, is quite feared among Bakugan and humans alike. Given how powerful she is, this fear is very understandable.
- Establishing Character Moment: Her first appearance emphasizes her motherly relationship with Shun, along with being a source of wisdom. Her first battle that we see on screen shows her turning Runo and Marucho's strategy to dust with just one attack, showing her as a very formidable fighter.
- Limit Break: Her Storm form has the most powerful attack next to Drago.
- Parental Substitute: In the English dub, she takes up the role of Shun's mother figure, and frequently serves as a voice of wisdom. When she departs him in New Vestroia, she tells Ingram to take care of "my Shun", indicating that she sees him as a son.
- Passing the Torch: She tells Ingrham to take of Shun when she informs Shun she will not return to Earth with him.
- Playing with Fire: She can set herself on fire, and cause tons of damage to adversaries, which is very fitting for a creature resembling a phoenix.
- Really 700 Years Old: It is heavily implied that Skyress is quite old by Bakugan standards, and her decision not to return with Shun is implied to be because she is starting to feel her old age.
- The Smurfette Principle: She is Shun's only female partner and in the Japanese version, where Tigrerra is male, she is also the only female Bakugan in the main cast of Season 1.
- The Stoic: Very little will take her by surprise.
- Tragic Keepsake: Shun's mother gave her to him before she passed away and therefore she's really important to him. The rare moments when he cries are when he thinks Skyress is dead, only for ber to come Back from the Dead like a phoenix.
- You Are Better Than You Think You Are: She gives this to Shun in his first episode, encouraging him to rejoin Bakugan, and telling him that his grandfather cannot control who he is.
Ventus Ingram
Debuted In: New Vestroia- Chuck Cunningham Syndrome: He is nowhere to be seen after the final battle of New Vestroia and no reason is ever given for his sudden absence, not even after The Bus Came Back in Mechtanium Surge.
- Crossdressing Voices: He was voiced by a woman during the first half of New Vestroia in the English dub.
- The Nth Doctor: After evolving into Master Ingram, his voice in the English dub shifts from its feminine-sounding tone to a deeper, more masculine-sounding one.
- She's a Man in Japan: Zig-Zagged. In the original Japanese dub, Ingram was always portrayed as male. Whereas the English dub portrayed Ingram as female during the first half of New Vestroia before correcting itself at the start of the second half of the season, portraying him as male from then on, to the point of even recasting the role so that Ingram would have a male voice actor.
Ventus Hawktor
Debuted In: Gundalian InvadersVentus Taylean
Debuted In: Mechtanium Surge Part 1- Chuck Cunningham Syndrome: Just like Ingram before him, no reason is ever given for his sudden absence in the second arc of Mechtanium Surge.
- Remember the New Guy?: Unlike Shun’s previous partners, who become his partner during their respective seasons, Taylean is already Shun’s partner at the very start of Mechtanium Surge and, unlike Marucho and Trister, it is never revealed how the two met.
Ventus Jaakor
Debuted In: Mechtanium Surge Part 2- Remember the New Guy?: Just like Taylean, he is already Shun’s partner at the very start of the second arc of Mechtanium Surge and it’s never revealed how they met.
