Voiced by: Yu Kobayashi (Japanese), Scott McCord (English)
Daniel Kuso, known in Japanese versions as Danma "Dan" Kūsō (空操 弾馬, Kūsō Danma^?, Dan ダン), is the human main protagonist in the series. Dan is an impulsive 12-year-old boy who, after finding out about Bakugan, wants to be the number one Battle Brawler. However, after teaming up with a Pyrus Dragonoid named Drago, Dan starts to realize there are more important things. He is 12 years old in the first season, 15 in New Vestroia, 16 in Gundalian Invaders, and 17 in Mechtanium Surge. In the beginning he is ranked #121, and by episode 39, he is ranked #1, and has become ranked #4 or under in episode 6 of Mechtanium Surge.
In New Vestroia, Dan returns to New Vestroia to help Drago save the world from the invading Vestals. Despite having just been introduced to the new Brawling system, Dan manages to get the hang of it before he battles his way into the Resistance by tying with Ace. He returns to Earth, following Spectra, Gus, and Lync into a portal with Mira and Baron. After losing Drago to Spectra in episode 16, his determination to get him back pays off as he and Drago reunite in episode 18. At the end of episode 19, he and Baron go back to New Vestroia through Dr. Gehabich's dimension transporter. In episode 20 he and Baron make it back to New Vestroia where they battle Mylene and Shadow in Beta City where they defeat them when Drago unleashes the power of the Perfect Core. In episode 26, he goes back to Earth, along with Marucho, Shun and the rest of the Bakugan. Various portals open up across the world, allowing all the other brawlers to reunite with their Bakugan.
After the destruction of the BT System, Dan and the Brawlers find out, with Lync Volan's help, that King Zenoheld is constructing a machine called the Alternative Weapon System which could destroy both Earth and New Vestroia. Dan along with the rest of restisance attempt to stop the alternative through any means necessary. At the end of New Vestroia he destroys the alternative weapon system with the help of his friends and allies. It is shown that he has been dating Runo at the start of the season. In Gundalian Invaders, Dan, Marucho, Shun, Jake, and Ren join Fabia in fighting an oncoming invasion of the evil Gundalians who want to rule over Neathia and have control over the Sacred Orb. In Mechtanium Surge, he and Drago have problem controlling their new powers they were given to by Code eve, and can sometime be taken over by Mag Mel and Razenoid and spawn Zenthon, a Mechtogan, which they eventually tame while in New Vestroia, after they returned to New Vestroia to control their new powers. They were the number one in bakugan Interspace until they were disqualified for using Zenthon accidentally, when battling Anubias for number one position. Dan later regained the title of Leader of the Brawlers after he apologized to the rest of the Brawlers minus Spectra.
He has a good relationship with his parents. His mom is a big yoga fan, while his dad is obsessed about pudding and has a personality similar to Dan's, only he's a little more clueless. It is possible that Dan plays guitar; in earlier episodes you can see a Fender Telecaster in the corner of his bedroom. In season 3, Dan has moved to Bayview Town because of his dad's work, and quickly becomes popular due to the fact he helped destroy Naga and King Zenoheld.

Together with Dan, they set out to defeat the Doom Beings, and rebuild the Perfect Core of Vestroia. He has the ability to radiate intense heat in battle dissolving everything around him. He is equipped with high intelligence. He is limited in battle mobility, but compensates for it through powerful strikes. He is able to infinitely evolve on his own and with every evolution it makes him stronger and it brings him one step closer to the Perfect Core.

• Delta Dragonoid II

Drago's first evolution during Dan, Runo, and Marucho's battle against Julio, Klaus, and Chan Lee in Drago's On Fire. He fought against Dual Hydranoid, and lost, sending him to the Doom Dimension.

• Neo Dragonoid

Drago's regeneration in New Vestroia, after the Ancient Soldiers separated him from the Perfect Core in Invasion of the Vestals. Although he is weaker than his previous form, he still is one of the strongest bakugan. He still has a connection to the Core, and can gain new abilities from it during emergencies. When Dan lost his battle to Spectra and Helios, he also lost Drago and because of his forced defection, his color change from a pure red to mixture of red and black (turning him into a dark and corrupted Hex Dragonoid). Drago has now also lost all his free will in this form and his pupils have been erased. Drago gained the ability to change into any chosen attribute at the cost of his physical health.

His Battle Gear is JetKor, a dual cannon blaster which can shoot an energy blast and defeat opponents. A lock on beam from the green lens freezes the opponent before the blaster attacks. It combines the two blaster beams into one enormous blast. It was used by Dan to combine with Drago in Fusion Confusion. The finished version was shown in episode 46. Unlike Helios' Battle Gear, it was made using Drago's own DNA so that it'd be more organic in nature, due to Drago's hatred of mechanical Bakugan and not wanting to become a cyborg like Helios. Because of this, JetKor acts like a part of Drago's own body when he uses it.

• Lumino Dragonoid

Drago's next evolution in Gundalian Invaders. He evolved in, when Neo Ziperator gave him the Element in The Element. He has four wings and a tail with a giant X shape on it.

From this on, he also started to use two Mobile Assault Vehicles: Raytheus, a large motorcycle like hover vehicle with a laser mounted in front, and Jakalier, a resemblance to the ocelot's glider with the only difference being Dan being able to ride inside of it.

• Blitz Dragonoid

Shun Kazami

Voiced by: Chihiro Suzuki (Japanese), Zachary Bennett (English)
Shun Kazami (風見 駿(シュン), Kazami Shun^?) was the former 1st ranked Bakugan brawler but after Masquerade showed up, he moves down to 6th, then back up to 5th after defeating Komba, then 2nd and ultimately to 3rd by the end of the first series. He is 13 years old, has black hair, which is tied into a long ponytail, and wears a purple jacket. He is a master of Bakugan and co-created the rules with Dan. He is also Dan's childhood best friend. Shun is a loner, a boy of very few words, but yet is willing to help his friends at almost every turn. He is a Ventus brawler and he approaches Bakugan like a ninja. He lives with his grandfather, who used to be a famous ninja warrior, who once expected Shun to follow in his footsteps instead of playing Bakugan. His Guardian Bakugan is a Ventus Skyress, whom Shun received from his sick mother. It is unknown if Shun has a father, this is not yet revealed, he has not appeared in any of the seasons. Skyress later evolved into Storm Skyress.
In New Vestroia, Shun came to New Vestroia completely by accident, and explained why Dan could not contact him in episode 1; he was up alone in the mountains working on his ninja skills, when a warp hole appeared and he was sucked into New Vestroia. He is 16 years old in New Vestroia. He made a cameo appearance in episode 4 when Marucho battled Mylene, but his face was not revealed as his hood covered it completely and was offered a place in the Vexos. After hearing that Skyress was taken captive, he rushed towards one of the cities to save her, but on the way, teamed up with Dan after rescuing him from Spectra and Gus. After being separated from Skyress, he teams up with Ventus Ingram, who he grabbed just before a beam pulled him into the ship. In the beginning, he does not get along with Ace very well, who refers to him as a "ninja-wannabe", but he is deeply admired by Baron who, in episode 7, even tries to imitate some of Shun's ninja moves but fails. He is taken hostage in episode 15, after being defeated by Shadow. Mira and Spectra later free him in episode 20, though he is unaware of this. He is reunited with Storm Skyress in episode 26 but she stays in New Vestroia, claiming that she was in his past and that Ingram is officially his new partner now. In episode 26, he goes back to Earth with Marucho, Dan, Drago, the other brawler's Bakugan, except for Storm Skyress. Shun returns to New Vestroia a few episodes after the beginning of the second series, and has a run-in with Lync Volan of the Vexos. Storm Skyress comes to his rescue, and after Lync is defeated by Shun and Ingram, Skyress bids Shun her final farewell. Shun is still the strong silent type and highly skilled with Bakugan, and is willing to help his friends whenever they need it. He helps Dan defeat the Alternative in the final episode of New Vestroia. Not much has changed for how he acts or looks, except for the fact that he has cut off his ponytail. His Trap Bakugan is Ventus Hylash and his current Guardian Bakugan is Ventus Master Ingram. Shun is 17 years old in Gundalian Invaders.
Shun returns in Gundalian Invaders as the second ranked battler in Bakugan Interspace and partnered with the synthetic Hawktor clone. At first he does not trust Ren and asks Fabia for her side of the story after the comes to Earth. Together they expose Ren for the liar he is and the brawlers side with Fabia at which point he is given the real Ventus Hawktor. When the brawlers head to Neathia, Shun helps restart the second defense shield by switching Bakugan with Dan and heading to the generator. The mission is a success, but it is later destroyed by Barodius and Colossus Dharak.
Shun returns again in "Mechtanium Surge" as co-captain of the Battle Brawlers. His Bakugan is Ventus Taylean which is a another Bakugan from Neathia. In episode 7, Dan disappears and Shun loses his cool as the new captain of the Battle Brawlers. He is also the only brawler to not have a love interest, other than Alice. Fabia Sheen is like a sister to him, as she reminds him of his deceased mother. He is believed to have feelings for Alice Gehabich; they seem to share some form of quiet understanding.

Choji "Marucho" Marukura (丸蔵 兆治, Marukura Chōji^?, マルチョ Marucho) - He loves to play Bakugan and is fonder of creating strategies rather than just using brute force. He used to be very obedient to his parents just because he wanted to please them, but that changed when he met the Brawlers and Preyas. He now has no regrets for the past, realizing that he only wanted to make his parents happy. He is an Aquos battler. His guardian Bakugan is his Aquos Preyas, which, later in the series, is revealed to have a special evolution, allowing him to burp up his two twin brothers, Preyas Angelo, who resembles an angel, and his brother, Preyas Diablo, who resembles a devil, and this allowed Marucho to not only keep Preyas in his original form, but his 'brothers' as well. Preyas was sent to the Doom Dimension in Marucho's battle with Klaus Von Hertzon. Later, Klaus showed up with Preyas. Dan and Runo found a way to get Preyas back through defeating him in battle. After this incident, Preyas burps up his brothers. Preyas also has an effect called "Change of Attribute", with which he can take advantage of the opponent's gate card. Preyas II has a split personality: Angelo Preyas is a bit more intelligent and nice compared to Diablo, who usually says exactly what Angelo says, but in a different way. He reached 7th in the rankings.
In New Vestroia, Marucho returns to New Vestroia with Dan after overhearing Drago's sly plan to leave Marucho, Runo, and Julie behind. While feeling depressed about no longer having a Bakugan, and having been separated from Preyas, Marucho sets out to find a new Bakugan, and he runs into Aquos Elfin, a female Bakugan who is also able to change attributes.

He helps fend off the onslaught of Zenoheld's robotic bakugan during the final episode of New Vestroia. He also gains a new Bakugan and will be back in Gundalian invaders. He's now believed to be about 16 in Mechtanium Surge.

• Preyas

Voiced by: Shawn Meunier

Preyas is a chameleon-like Bakugan with strong loyalty to Marucho. His greatest strength is that Preyas can change his molecular structure allowing him to turn to Darkus or Subterra. Even though he has a menacing appearance, he is shy and comical. Small in comparison to the other monsters, Preyas makes up for it in speed. Preyas reappears in Return to New Vestroia.

Instead of evolving, Preyas regurgitated a mutated version of himself. The second preyas has a split personality, one side is hotheaded and extremely rude, and the other is peaceful and overly polite. The rude side looks like demon version of Preyas and is a pyrus/aquos hybrid; the polite side looks like an angel version of Preyas and is a haos/aquos hybrid. Although the original Preyas has been found in New Vestroia, Preyas II hasn't even been mentioned.

Tigrerra later evolves into Haos Blade Tigrerra.Though underage (in the first season), she helps her parents run their family business in a cafe. Alice also works there. Runo is a bit jealous of Alice because she attracts a lot of the guys at the cafe, which draws attention away from her. In one episode, Alice was not working at the cafe, and the customers were so rude and ignorant, they called out to Runo remarks like, "Where's Alice?!", and, "We want Alice!!", but she just brushed it off and yelled back at the customers, showing her rather impatient and strong attitude. It is revealed in episode 32 that she knew Dan from when she was little, but didn't realize it because she didn't catch his name. She reached 6th in the rankings. She has not brawled for the final showdown against King Zenoheld as Tigrerra chose not to brawl and put her into trouble. In New vestroia it appears she is dating Dan, as they are both 15 years old and old enough. She missed Dan so much she teleported herself to new vestroia but she was half way there. She's believed to be 16 years old in the third season's timeline. Even though she didn't appear in Gundalian Invaders as an individual, in True Colors, she was shown in a flashback from New Vestroia, and in Mobile Assault, she was shown in a picture with Dan and Julie. In Mechtanium Surge, she was shown in another picture with Julie in the episode Back in Sync. However, she finally made her return in the episode Enemy Allies, where she delivers the battle suits to Dan, Marucho, and Shun as they battle Wiseman. From that episode on, she and Mira helped to deliver the Battle Suits to the Brawlers whenever they needed them.

Julie Makimoto

Voiced by: Risa Mizuno (Japanese), Katie Griffin (English)
Julie Makimoto, Julie Heyward (ジュリー・ヘイワード, Jurī Heiwādo^?) in Japan, is a 12 year old girl from Australia who tries to stay happy even when the worst has happened (for example, when Billy ended up under the control of Masquerade); she acts happy after something bad happened but she generally does that just to cover up her true feelings. Julie forgets things easily, proving that she is a little scatterbrained at times. In the Japanese version, Julie spices her speech with American phrases, differentiating her personality from the others. She is a Subterra battler and her guardian Bakugan is her Subterra Gorem. Gorem then evolves into Subterra Hammer Gorem. Julie has a sister named Daisy who has bested her in everything since she was a child. She reached 8th in the rankings. She chose not to brawl against Zenoheld in the final showdown as Gorem did not want to put her into trouble. She returns in Gundalian Invaders as a neighbor of Dan's once he moves. She works at a cafe and in Revelation, it is revealed she is a cheerleader for the team Jake plays for. This strongly suggests she is already in high school in her first year with Dan. She's believed to be about 16 years old. In Brawler To Be, Jake is having his first ever battle and Jake gets scared, so Julie teaches Jake some lessons. Her role is basically that of a supporting character. Julie returns in Mechtanium Surge as a news reporter.

A Bakugan that resembles a golem. Gorem is one of the largest monsters; its body is composed of exceptionally dense cells making it very heavy. When battling it uses its massive fist and a shield decreasing the G power of any Bakugan. Normally gentle and obedient, only Julie can calm it down when angry. It evolves into Hammer Gorem.

• Hammer Gorem

Hammer Gorem is the next evolution of Gorem. It is a stronger more powerful evolution with an impressive coat of armor and bull-like horns protruding from its head. Hammer Gorem wields a highly destructive double-sided hammer to pound its enemies into the ground. He later went back to New Vestroia with Blade Tigrerra and Preyas, though this wasn't shown. In Blast From the Past, he was killed by Mechtavius Destroyer, but was ressurrected when the Brawlers went back in time to stop Mechtavius Destroyer from destroying the universe.

Alice Gehabich

Voiced by: Mamiko Noto (Japanese), Emilie-Claire Barlow (English)
Alice Gehabich (アリス・ゲーハビッチ, Arisu Gēhabitchi^?) is a 14-year-old girl from Moscow, Russia. Although she knows almost everything about the game, she rarely plays it. She usually just gives advice to the other brawlers, which she prefers over battling. Alice is kind and caring worried for others and does not think of herself. Alice was sometimes unconsciously possessed by "Masquerade" (her mysterious alter-ego), and with a sudden jolt, her hair rises up and turns blonde, and clothes and a mask come out of nowhere on her, and finally, she turns into a male. This was caused by her exposure to the Silent Core. Alice might seem to be less important than the other brawlers, but in fact she plays an important part, not as Masquerade, but without her, the brawlers might have already lost to her alter ego. Michael Gehabich is her grandfather; who she constantly worries about after finding out that Hal-G is his alter-ego and that he works for Naga. Alice and Marucho are the 2 brawlers who mostly use strategy. However, unlike Marucho, Alice gives her strategies to the other brawlers. She left the Brawlers after finding out that she was Masquerade out of intense guilt over what she had done as him, but later returns in time to save Dan. Her guardian is Alpha Hydranoid, which she received from Masquerade after he left her body (something she initially resents, because she believed that she needed him). Alice is 17 years old in New Vestroia, 18 years old in Gundalian Invaders, and 19 years old in Mechtanium Surge. Alice has a special ability that most brawlers wish to have, she can see the power level of any bakugan on the field even if the bakugan is not playing! Which is why she does not have a baku-pod. She might have this ability because of Masquerade. She ultimately ends up at 2nd place at the end of the series. It is still unknown if Alice is an orphan. She appears in Surprise Visitor and takes in Lync in Gate Crashers. In New Vestroia it is stated after Alice is reunited with Hydranoid, that she hates brawling because of what happened in the past but when Shadow attacks in Shadow Attack, she has no choice but to fight back. She and her grandfather also manage to find the route to the Mother Palace in All For One. She does not have a love intrest, but is believed to have feelings for Shun Kazami.

• Hydranoid

Voiced by: Izō Oikawa (Japanese), Craig Marshall (English) and Robert Tinkler (S2E26)

Alice's guardian Bakugan (Masquerade's before). Hydranoid is one of the strongest species with a body composed of a highly intelligent, independent cell structure. It is completely controlled by Masquerade and obeys all of Masquerade's commands. This one-headed Hydra-like Bakugan has very strong armor, a dragon-like face, spines all over its body, and a sharp flail for a tail. Its mobility is extremely slow, but can battle all species with its extremely powerful and forceful strikes. Hydranoid is a mercilessly cruel and unforgiving monster, not to mention extremely violent and arrogant that feeds off the power of Bakugan sent to the Doom Dimension. Like his old nemesis (now friend) Drago, Hydranoid can evolve into a more powerful monster.

• Hydranoid (Dual Headed) (Dual Hydranoid)

Hydranoid's first evolution with two heads. Hydranoid now also has two tails. He seems to be partially mechanical even though his evolution was completely natural, unlike Helios who was evolved by Vestal Technology.

• Alpha Hydranoid

Hydranoid's second evolution with three heads. Even more of his body looks mechanical, and he now has three pairs of wings. The armor on the front of his body can rotate like a huge grinder after he ensnares his opponent with metal cords (this is probably a strange biological feature). He now battles as Alice's Bakugan guardian (because the Silent Core's negative energy finally leaving him and Alice), caring for her as much as she cares for him. He can also shoot hot fire that can melt all attributes. In Blast From the Past, he was killed by Mechtavius Destroyer, but was ressurrected when the Brawlers went back in time to stop Mechtavius Destroyer from destroying the universe.

Osamu Jō (城 治, Jō Osamu^?, nicknamed Joe (ジョウ, Jō^?)) in Japan, is also known as Webmaster Joe (ウェブマスター・ジョウ, Uebumasutā Jō^?). In the first season, it was revealed that due to an unknown health condition, he basically lived in a hospital for some time. During this time, the Brawlers thought that he was working for Masquerade. After Dan confronted him, he told Dan that he would only tell him the truth if Dan could beat him in a battle. In the middle of the battle, Joe fainted, and when he awoke he revealed that the brawlers' theory was untrue and he actually sent a message to all of the Bakugan players around the world to warn them that Masquerade was plotting against them. After the truth was revealed, they asked him if he wanted to become a Battle Brawler, which he gladly accepted. He then revealed that he and his mother were going on a road trip for the time being, to see the world outside of the hospital. Sometime later, after he moved to the Brawlers' neighborhood, he found Wavern, who had the Infinity Core hidden inside of her. It was also revealed that Wavern was Naga's twin sister and that he was looking for her in order to absorb the infinity core. Joe was the first person to beat Masquerade at Bakugan, after he obtained Wavern. In the end of the first series, Joe is seen with Chan-Lee, sitting on a bench.

Resistance

Mira Clay

Voiced by: Risa Yukino (Japanese), Alyson Court (English)
Mira, a 16-year-old Vestal girl, formed the Bakugan Brawler Resistance, after witnessing the tortured Alpha Hydranoid speak out in vengeance to the invaders, to free all the captured Bakugan from Prince Hydron and the Vexos. At the end of Surprise Visitor, she along with Baron travel with Dan back to his world. In Unmasked, Mira challenges Spectra to a battle and if she's victorious, Spectra will be unmasked. If she loses, however, she has to join the Vexos, and even battle against her own friends. She told herself in the beginning that her hero was always her brother, Keith, but forced herself to change her mind about it after Spectra unmasks himself in front of her, revealing that he was her 'hero'. Baron described her as 'intense'. She betrays the Brawlers in Family Ties as she says that she wants to stay with Keith, once telling the others on Earth that Spectra is her brother. She returns to New Vestroia through the portal Apollonir opened with Spectra, Gus and Lync after revealing her betrayal. In Beta City Blues, she reveals that she has joined the Vexos, but is really wondering what Spectra is up to. In Brotherly Love she challenged her brother to a battle and if she wins, she goes back to being with her real brother and not Spectra; however, if she loses, she will have no choice but to serve Spectra. She later lost the brawl. She is regretful of this as she says, "I'm sorry my friends" after the battle, and is also seen crying as she has no choice but to be an enemy to the Resistance. She later returns to the Resistance. She returns to Vestal with Ace and Baron and their Bakugan, in case the Vexos will want to take back New Vestroia for themselves in the future. Mira visits the Brawlers on Earth for a visit, but soon returns to Vestal, this time with Dan and Marucho, and they meet up with Ace and Baron at Klaus Von Hertzen's estate. Following the defeat of Zenoheld she returns to Vestal with her brother, Gus, and the rest of the Vestal Resistance. She also has a brother that she desperately wants to find after he disappeared during Hydranoid's rebellion. Although she is the leader, she is not necessarily accepted by the others, as she has a small tendency to go off on her own. She prefers the Subterra attribute. Her main Bakugan is Subterra Wilda and her Trap Bakugan is Baliton. She has a crush on Dan and is presented several times: in Six Degrees of Destruction where she tried to see if Dan would notice her change in hair style and in Reunion she was extremely sad to the point of crying when she thought Dan was caught in the explosion and upon knowing he survived she jumped into Dan's arms hugging him. In Surprise Visitor, Dan brought up Runo and Ace said Mira sounded jealous (even though Mira is jealous of Runo, she is still friends with her). It was also the main reason for Ace's hostility to Dan because Ace has a crush on Mira. Mira returns in Bakugan: Mechtanium Surge where she helps the brawlers by creating battle suits for their bakugan.

• Wilda

Voiced by: Ron Pardo

Wilda is the guardian for Mira, the leader of the Resistance and has a deafening battle cry to scare away opponents.

Mira's Ankylosaurus-like Bakugan Trap in the shape of a sphere with spikes around it. Baliton merges with Wilda during battles. Like Wilda, he is slow to move, but he uses massive weight to crush his foe. His brown exterior is the perfect camouflage when battling in the desert. Horns cover his body from head to tail, and his multi-horned tail with sharp nails at the end can swing around like a baseball bat.

• Roxtor

Ace Grit

Voiced by: Yasuaki Takumi (Japanese), Alex House (English) in ep. 1-47, David Reale in 48-52
Ace is a Vestal boy, 16 years of age, and the Darkus battler of the Resistance with Darkus Percival as his guardian and Darkus Falcon Fly as his trap. He is often very rash and does not think things through. As revealed in episode 13, Ace was once a top brawler in the Vestal tournaments, but stayed away after Hydron used them to find strong brawlers. Mira approached him, invited him to the Resistance, and gave him Percival. Ace first shows his skills as a brawler when he battles Dan in the second episode of the series: Ace refuses to accept humans on the Resistance and challenges Dan to a battle to prove his skills. After three hours, the battle ends in a draw and the two become fast friends.
In Return of a Friend, he and Mira had an argument because Mira wanted to postpone destroying the dimension controllers and find her brother, however, Ace refuses to allow her to go because he fears of the dangers she may face. In Voices in the Night, he says, "This is for Mira", which may also hint that he likes Mira. After Mira and Baron went to Earth with Dan, he worries about Mira and when he hears her voice in the night, which was really Shadow Prove who was leading him into a Vexos trap, he tries to save her, which further proves his love for Mira.
In What's the Plan?, when he and Shun are forced to fight together in a tournament, Ace wears a purple and black mask to disguise himself while tensions rise between the two of them and they fall close to losing. However, on the edge of defeat, they put their differences aside and Ace works together with Shun after realizing he was just trying to help. Shun remarks that he is very much like Dan. In Voices in the Night, after falling for the Vexos trap laid out by Mylene, he loses in battle to her and becomes a hostage. After Marucho and Shun are also captured, they are relocated to Beta City, where they are freed by Mira and Spectra, though they are unaware of this. When he's told that Mira betrayed the Resistance he refused to believe it due to his feelings for her and gets a little violent by grabbing Dan's collar, but accepts it as the truth when Baron insists Dan's telling the truth. In Wall To Wall Brawl, When the Resistance infiltrate Gamma City, he and Dan battle Mira and Gus. Mira ends up betraying Gus and Ace tells her he always believed in her, Mira smiles happily at him and is glad to be back on the resistance.
After Skyress, Hydranoid, Gorem, Tigrerra and Preyas are rescued, Ace and Percival return to Vestal with Baron and Mira and spread the truth about the Bakugan and the Vexos' actions. After Percival receives the Darkus attribute energy from Exedra, Percival evolves to Midnight Percival. While Baron searches for an apartment to move into, Ace helps out but is ambushed by Mylene. He nearly loses but is saved by Klaus. Ace travels to Earth with the Resistance to hide out from the Vexos and protect the Attribute energies. While in hiding, Julie develops a crush on him after watching him work out. When Marucho invents Bakugan Interspace, Ace is set to battle Billy, but also challenges Julie so as to not "get in between the two love birds." Despite Percival becoming immobile, Ace is victorious thanks to his evolved trap Darkus Flash Falcon Fy. After the Resistance decided to go on the attack, Ace and Marucho encounter Lync and Shadow at the Mother Palace. Due to the rigged field, Ace and Marucho lose and the Darkus energy is taken.
After destroying the BT System, Ace returns to Earth with the Resistance and witnesses Dan's ultimate battle with Spectra, in which he decides to turn over a new leaf. After Keith becomes an official member of the Resistance, Ace becomes jealous of the time Keith spends with Mira. But Julie and Percival assure him that Keith and Mira are only siblings and that Mira is just happy to have her brother back.

• Falcon Fly

Ace's Bakugan Trap that Percival can stand and ride on it. It takes the shape of a rectangular prism in Trap form. Falcon Fly is a Bakugan Trap that combines with Percival. Its large wings make it quicker than a dragonfly while its dark color makes it difficult to see at night. It has a very thin body that makes it almost invisible when attacking straight on. To destroy its enemies, Falcon Fly shoots laser blasts from its eyes. The pattern on its body and tail is similar to the pattern on AirKor's wings.

  Baron Letloy

Voiced by: Ryuichi Kubota (Japanese), Cameron Kennedy (English)
Originally, Baron fought with Tigrerra, but lost her to Spectra and Helios. He used Haos Nemus as his main Bakugan and uses Piercian as his Trap Bakugan. In Surprise Visitor, he says that he had always wondered what it would be like on the other side of the portal, which was the portal that led Runo to New Vestroia from Earth. In the end, he decides to follow Dan, Mira, and Runo to Earth in order to stop the Vexos from destroying it. Baron admires Runo as one of the six original Battle Brawlers but Runo's father does not like the fact that he does. He returns to New Vestroia with Dan through Dr. Gehabich's dimension transporter. He seems to be very fond of the activities done on Earth, especially by Dan e.g. taking baths. In Beta City Blues, he and Dan made it back to New Vestroia where they battled Mylene and Shadow in Beta City. Baron was defeated helping Dan and Drago, but he still was able to keep Nemus. He returns to Vestal with Ace and Mira with their Bakugan, in case the Vexos will want to take back New Vestroia for themselves in the future. In Revenge of the Vexos, after the Vexos return Baron brawls Prince Hydron and loses the Haos attribute energy. Baron is currently 12 years old, confirming this in the English version by saying, "I'm almost 13 ya know!" He is a huge fan of the Bakugan Battle Brawlers and the six fighting Bakugan as displayed by his reaction to first meeting Dan, Marucho, Drago, and Shun. He seems to always embarrass himself in front of Dan, Marucho, and Shun. According to Mira, he has a poster of the Bakugan Battle Brawlers up on his wall. From what was shown in Revenge of the Vexos, Baron has a large family and is very caring for his many younger brothers and sisters. He is the youngest and most emotional of all the brawlers.

• Piercian (Guardian)

Baron's Bakugan Trap, and is in the shape of a cube. It is similar to another trap Zoack. In episodes 23 and 36, Baron says "Guardian" instead of Piercian. This could be like Shun's Trap Hylash, who he nicknamed Slash. It does not have a known evolution. Piercian is a Bakugan trap that connects with Nemus to create a dynamic one, two punch. He has two colossal shields attached to his forearms for protection, which he can also throw like discs to crush his challengers. The shields can also be used as mirrors that reflect Nemus's light rays. Piercian's towering block legs provide tremendous stability to sustain the mightiest of punches.

  Keith Clay / Spectra Phantom

Voiced by: Yasuhiro Mamiya (Japanese), Dan Petronijevic (English)
At the beginning of the series, he would only obey Prince Hydron. Little was known about Spectra, but it confirmed he is very powerful and thinks highly of his skills. He was the Vexos' strongest battler and used Pyrus Helios as his main Bakugan and Metalfencer as his Trap Bakugan. After seeing Drago's powers, Spectra said that he's not going to let it be a 'play thing', which means that even when he captures Drago, he will not give him to Prince Hydron. In What's the Plan?, Mira noticed possibility that Spectra could be Mira's brother, Keith. How he became Spectra is unknown. He also wished to join forces with Dan and the Resistance so they could take Prince Hydron down together in an attempt to rule New Vestroia and Vestal. After Gus lost to Mira, Spectra unmasks himself, proving himself as Mira's older brother, Keith. When he, Gus and Lync traveled to Earth, Mylene took over as leader. Meanwhile, Spectra won the Bakugan brawl against Dan and Drago, and takes Drago. Dan defeats him and a corrupted Drago during their brawl with the help of Pyrus Apollonir. In episode 19, he convinced Mira to join him. He needed her help on his "ultimate plan", which was creating a Cyber Helios and duplicating the power of the Perfect Core, planning to use this Bakugan to overthrow the Vestal royal family. In Brotherly Love he battled Mira and won with his new Mechcanical Helios. In episode 24 he took several Mechanical Bakugan for his own purpose of making Maxus Helios to defeat Dan. He does not return to Vestal, but he remains in the other rim of the planets area in a ship with Gus, Helios, Elico, Vulcan, and Brontes.
Spectra appears again in Spectra Rises, battles Dan, and loses, but nevertheless says he will see him again soon. As shown in Spectra Rises, he used the forbidden card "Chaos Ability X" on Elico, Vulcan and Brontes, which forced their unnatural evolution, making them his battle weapons. In All Or Nothing, Spectra transports Dan to his ship upon reaching Earth to retrieve the Perfect Core from Drago. During their battle, Spectra seems to have a change of heart, referring to Dan as his friend in thanks for enlightening him. He reveals shortly that using data on Bakugan evolution, he plans to bring out even further power from within the Bakugan. After they arrive at the Mother Palace, he states that the Resistance is on their own in shutting down the BT system. After confronting Zenoheld however, Gus is defeated and Spectra soon forms a temporary alliance with Dan to avenge his fallen comrade. After the Pyrus attribute energy is absorbed and the BT system begins to activate, his ship is used to transport all of the bakugan on New Vestroia to Earth. When time begins to run out, and the Resistance decides to bail out while they still can, Helios leaves Spectra and confronts Drago about staying to evacuate the remaining bakugan. The two decide to head off and destroy the BT system, and after Drago evolves by absorbing the attribute energies, Helios and Spectra once again become Dan and Drago's rivals before leaving New Vestroia. But in the end of Spectra's Last Stand, Spectra agrees to join Dan and the Resistance and takes off his mask. It is shown in the same episode that like Mira, he may have some sort of telepathic ability, as he spoke to Dan and Drago.
Spectra has returned in Mechtanium Surge. He was first seen in the shadows receiving a distress call from Marucho who was fighting against the rampaging chaos bakugan, although Marucho and Shun were surprised that Spectra came to help they were still glad. Spectra left afterwards but not before telling Dan that he has changed from the old Dan. Spectra and Helios returned to help the brawlers again when they were fighting against Mag Mel on Gundalia and before they left Spectra said they had nothing left to worry about over the brawlers. When Dan thanked the two of them for helping Spectra said they could call on him anytime.

Spectra's Guardian Bakugan. Helios is an evil dragon that obeys every command from the heinous Spectra. Its mammoth wings allow it to move swiftly and avoid quick attacks. Helios has poisonous tipped thorns covering its body. From its mouth,it can shoot cannonball fire blasts with rapid speed. The key point of the original helios is that 1 he uses his abilitie general quasar which is usually unused for the rest of the bakugan series. Another key point being that in this form with help from the forbidden cards he manages to defeat drago . but for some reason spectra doesn't use the forbidden cards ever again.

• Cyborg Helios

Helios suggested that he be turned into a cyborg, since it would not have any of the weaknesses of a completely mechanical Bakugan. A computer voice can be heard when he uses his new ability FARBAS to repair himself and increase his power to match his opponent's.in this form helios can (a)use more cybernetical attacks like ragnorok cannon which soon begins to evolve the realsistic gun like weaponry in the bakugan series.

Castle Knights

  Fabia Sheen

Voiced by: Haruhi Terada (Japanese), Stephanie Anne Mills (English)
A She is the younger sister of Serena Sheen, the former Neathian Queen. Fabia's reason for brawling is to save her planet from the Gundalians. She is also the fiancée of the former Captain of the Castle Knights who is deceased.
She seems to have the same kind of love for freedom and intiative to act as Mira does . She also seems to be strong, because she shoulder threw Dan twice in episode 3, the first was by accident and the second was when she got mad at Dan after losing, and in episode 10 when Zenet tried to take her as a hostage and Fabia threw her hard on the ground. Those incidents may prove Ren Krawler's statement about the Neathians' specialty at close combat, although most of what Ren said was a lie to put down the Neathians. Fabia owns Aranaut, the bakugan of her deceased fiance, Jin. After she becomes the new Neathian Queen in Bakugan: Mechtanium Surge, she gives Aranaut to Captain Elright

After Mag Mel's defeat Rafe and Wolfurio returned to Neathia.

  Gundalian Forces

  Ren Krawler

Voiced by: Hirofumi Nojima (Japanese), David Reale (1-10) and Peter Cugno (English)
He is a 16 year old Darkus Brawler. Ren was the leader of a secret agent group sent to Earth by Emperor Barodius to find the DNA Code. He is an alien disguised as a human sent to find the best brawlers and defeat the Neathians. Ren comes from the underground world of Gundalia where he was kept, unknowningly, by the Emperor's family due to his possession of a dark Bakugan with a powerful ability. He is a member of the Twelve Orders because he thinks that would save his people if he works for them. He is attempting to trick the brawlers into thinking that the Neathians are the ones trying to conquer Gundalia. His Bakugan partner is Linehalt. He makes an appearance at the end of the final episode of New Vestroia. In A New Beginning it was revealed that he helped put Bakugan Interspace online. He has a battle with Dan, which ends up as a draw. In Confrontation Ren shows too much care and loyalty to his home planet. It's possible that even if Ren and Marucho are current enemies, they still share a big friendship thread. It also seems Ren does not want to fight the brawlers because he still remembers their friendship.
After Sid, Lena, Jesse and Zenet were punished by the Twelve Orders, Ren feels incredibly guilty over what has happened, especially since he has gotten off scott free each time. While he was fighting with Dan, he was surprised to see that Sid is alive and is relieved to hear from him that the others are alive as well. Sid saves Ren from Dharak's attack and falls to his death, not before giving Ren his Rubanoid. After some serious thought and battling with Dan, Ren decides to turn on Barodius and do something he should have done a long time ago: fight alongside his true friends. At first, the Neathians do not accept him, but after battling Fabia, where he lost, Fabia offers him her hand and he goes with the Brawlers. He is now one of the Castle Knights. After the war is over Ren returns to Gundalia along with his teammates and Nurzak.
In Mechtanium Surge Ren has become the commander of the Gundalian Forces and is reunited with the Brawlers when they come to help Gundalia fight against Mag Mel.

  Vexos

Zenoheld

Voiced by: Kōji Ishii (Japanese), John Stocker (English)
The central villain of the second season. The King of Vestal and a leader of the Vexos. He is the one responsible into invade New Vestroia, capture the Bakugan and them to fight each other to create Mechanical Bakugan as his own weapons.
In the first half of New Vestroia, Zenoheld had little interaction with the Resistance or the Vexos. The only time he appeared was when he nagged Hydron for not taking better care of the Dimension Controllers. He seems to be impatient with him due to his constant failure. He will also check in with him and make sure that he is still on the right track, although Hydron shrugs his warnings and discipline off, as he thinks he is doing fine without his father’s constant nagging.
In the second half of New Vestroia, he flees Vestal and resides in his palace on the outer skirts of the galaxy that is remote from civilization. He is revealed to be a brawler and he sends a message to the Six Ancient Warriors to surrender their Attribute Energies to him so that Professor Clay can power up the Bakugan Termination System. They decline his offer at first, but then they decide to battle him. When they arrive, Zenoheld reveals that he owns a Mechanical Bakugan, Pyrus Farbros. After a tough battle, Zenoheld comes out victorious, but the Ancients escaped and entrusted their Attribute Energies to the Resistance.
After hearing the news of the Attribute Energies being dispersed throughout New Vestroia and Earth, he entrusts Mylene Pharaoh with the duty of picking another Subterra Brawler to replace Gus in the Vexos. She chooses Hydron, and he says that he “couldn’t have picked better himself”. After Hydron gains the Haos Energy after he defeats Baron in a brawl he says “I knew I could count on you...Hydron”, revealing that he now trusts him with responsibility more than he did in the first half.
Soon after Mylene and Volt come back from brawling, he sees a transmission from Spectra, saying that the Vexos, Hydron and Zenoheld himself were responsible for the mess in the previous season. This causes him to send Shadow Prove to seek out Dan and the others so that he will get the Attribute Energies first. But when he does, he realizes Spectra jammed the transporting system, making it impossible to travel to Vestal and back. This infuriates him, knowing that he is up to something. Eventually, though, Shadow goes to Earth and brawls Chan Lee and Alice (who do not have any Attribute Energies). He wins and proves himself to Zenoheld. He also brawled against Gus Grav, and won with the Farbros-Assail formation, and destroyed Blast Elico, and his Bakugan Trap Hexados. However, Gus and Vulcan survived the final blow.
In BT: The Final Battle, he helps Hydron brawl Mira Clay, Dan Kuso and Spectra Phantom. However he does not brawl until Hydron loses to Dan and Spectra. He wins but Farbros was destroyed and he takes the Pyrus energy from Cross Dragonoid.
In Phantom Data Attack, he almost launched the Bakugan Termination System, and then Cross Dragonoid and Helios MK2 try to destroy it, but fail. When Cross Dragonoid brings the B.T. System into the atmosphere and absorbed all the Attribute Energies from it Zenoheld was furious and was eventually going do something about it.
In Fusion Confusion, he takes his frustration out on Hydron demanding to know whose fault it was for the destruction of the BT System. After Professor Clay told him about how he could rule over all dimensions he had Clay create the Alternative Weapon to destroy Earth and Vestal.
In An Heir To Spare, it is revealed that Zenoheld took his anger against Hydron for another time. He battled against Hydron to see who would have the throne, and won. Hydron was then jailed, along with Gus Grav. Zenoheld stated that they were never destined to be father and son.
In Ultimate Weapon, he battled Spectra, who rammed into his palace. During the entire battle he was losing, even with Assail Farbros, because later Gus joined Spectra. However, when Farbros combined with the Alternative, he overpowered both of them.
In All For One and Final Fury, he uses the Alternative against the brawlers, but when the Alternative was destroyed Farbros was destroyed by Dryoid. Hydron then used Dryoid to trap Zenoheld until the alternative explodes, supposedly killing all three.
He is currently mentioned by Dan in the season 3's introduction (first fourteen episodes), and also appeared in the next video game, Defenders of the Core (along with Spectra and the other Vexos, excepted Hydron and Clay).

• Farbros

Zenoheld's Mechanical Bakugan. He was created with the data of ALL Bakugan launched on New Vestroia. Clay called Farbros the mighty and feared creation on all the Vestal realm. Like Altair and Hades, it's a gigantic cybernetic Bakugan but is able to repair itself (like Cyborg Helios). Zenoheld controls it manually from inside a cockpit. It is powerful enough to challenge all Six Legendary Soldiers at once. It was destroyed after the BT System got all six attribute energies, but was repaired in episode 49 and used to link to his Alternative Weapon System. It is destroyed along with the Alternative.

• Assail System

A Mechanical Bakugan Trap which combines specifically with Farbros. It is similar to Battle Gear. The Assail System comes out of nowhere and combines with Farbros. When combined with Farbros, Farbros gains 4200 Gs and is called Assail Farbros. It was created by Professor Clay for King Zenoheld, in episode 50 the Assail System comes off Farbros and is replaced with The Alternative Weapon System. When it comes out of nowhere it is in two parts. It has been scattered across the galaxy.

  Professor Clay Fermin

Voiced by: Kenichirou Matsuda (Japanese), Scott McCord (English)
Professor Clay Fermin is Mira and Keith's father who created the first Mechanical Bakugan named Ventus Altair for Lync in Cyber Nightmare. He also appeared in Facing Ace with Alpha Hydranoid. He also created Darkus Hades and Trap Darkus Fortress for Shadow. Professor Clay is also credited for making the Cyber Bakugan that were intended for Prince Hydron but are being reprogramed for Spectra by Lync. He also turns Pyrus Helios into Pyrus Cyborg Helios after Helios gave him the idea of a Cyborg Bakugan.

As of Ultimate Weapon, he has finished the Alternative Weapon system (which he based on Farbros). In Final Fury, he was killed along with Hydron & Zenoheld when the Alternative System was destroyed, while he was watching the video sent by Fabia about the Bakugan at war.

Hydron

Voiced by: Soichiro Hoshi (Japanese), Lyon Smith (English)
Hydron was the commander of the Vexos, the Vestal Prince and Zenoheld's son. He tried collecting all six of the fighting Bakugan that saved Vestroia and keep them as trophies. The Vexos continually failed to bring him Drago, the last of the six fighting Bakugan needed in his collection, as he had already in possession of Gorem, Preyas, Tigrerra, Skyress, and Hydranoid in a petrified statue form. He is shown to have a habit of twirling his hair between his fingers. In episode 17, he may have been aware that Spectra had Drago in his hands. At the end of the first half of the series, he flees New Vestroia with Mylene, Volt, Lync, Shadow and Professor Clay. He attempted to kill Spectra due to Spectra's betrayal but failed due to Spectra's own determination for power. He lost the six fighting Bakugan to the Resistance in Reunion. In Revenge of the Vexos, he started brawling with Subterra Bakugan, using Dryoid when he is sent to obtain the Haos Energy from Baron's Mega Nemus, and succeeded. In Elfin On the Run, he teams up with Shadow Prove to try to obtain the Aquos Energy from Marucho and Aquos Minx Elfin and succeed in defeating Elfin, but lost to Preyas. Later, he battles Dan and Spectra at the Mother Palace, but loses to Helios and his new Battle Gear. In Volt's Revolt, after Volt leaves the Vexos, Zenoheld orders Hydron to deal with Volt. Volt defeats Hydron in a brawl, but Hydron starts to go insane and throws a dimensional grenade at Volt to send him to another dimension. He is almost pulled in with Volt, but escapes in the nick of time. In Payback, when Lync copies the plans for the Vexos' new Alternative Weapon system, Hydron follows Lync and defeats him in a brawl. He then throws another dimensional grenade at Lync to send him to the same dimension as Volt. When he returns, he is looking for his father's approval, but Zenoheld ignores Hydron blaming him for his minions' failures. This causes Hydron to face his father. When he does, he loses and is put in a cell across from a shadowed figure, which is possibly Gus from the figure's blue hair. In the next episode, it did turn out to be Gus, and they had a brief conversation before the opening. Gus later tricks Hydron, after a string of dog-related insults on Gus's part, into brawling with him. This breaks the doors on the cells releasing both. Before flying off, Gus says that he could have asked Hydron nicely but that would probably not work only further angering Hydron. He is later seen making his own, escape attempt on Dryoid. He makes it to the ship with the other Bakugan Brawlers. They forgive him and he is presumed that he was killed after ensuring that his father will not escape the blast from the ALternative's destruction. His last words were "Volt, Lync, I'll be there soon." The blast occurred right after, so it is believed that he is dead.

• Dryoid

Prince Hydron's Mechanical Bakugan that looks like Robotallion, but has a more streamline-like armor. It is also a Cybernetic Bakugan. It fights with a lightsaber-like weapon, although its fighting style is more like a samurai.

  Mylene Farrow

Voiced by: Fuko Saito (Japanese), Bailey Stocker (English)
Mylene is the only female in the Vexos. She did not trust Spectra and enjoys doing things her way, but is still a loyal member of the Vexos. She becomes the leader of the Vexos after Spectra and Gus travel to Earth. However, King Zenoheld later became the ruler of the Vexos. Mylene used Aquos Elico as her main Bakugan, and Aquos Tripod Theta as her Trap Bakugan. She defeated Ace in episode 13. She enjoyed the power of being the leader of the Vexos and, like Spectra, is tired of Prince Hydron bossing her around all the time. She also gets annoyed easily by Shadow Prove, who will not stop following her everywhere she goes. In episode 20 she and Shadow Prove battled Dan and Baron in Beta City and were defeated when Drago unleashed the power of the Perfect Core. She escapes New Vestroia with Volt, Shadow, and Lync, saying that it could be destroyed by the battle between Spectra and Dan and their Bakugan, discarding her guardian Bakugan together with Volt's Haos Brontes, as she thinks that Bakugan with feelings are useless. She later flees to Vestal with the Vexos, Prince Hydron, and Professor Clay, leaving Spectra and Gus. She later duels Ace in order to obtain Percival's Darkus Energy wielding Aquos Macubass, but was defeated by Ace and Klaus. She than went to Earth with Lync to draw out the brawlers. They found Runo and Mira and battle them. Mylene defeats both Runo and Mira, thus gaining the Subterra energy. She later goes on to defeat Shun and Baron alongside Volt, taking the Ventus energy. After Zenoheld's announcement to create the Alternate Weapons System that would destroy both Vestal and Earth, she appears when Volt was about to leave, warning him about his idea. When he leaves, she wishes him luck, and appears saddened when she hears what happened. In episode 48, Mylene is ordered by Zenoheld to retrieve the Brawlers Battle Gear data and DNA code for the Alternative Weapons system. She is then lured into Bakugan Interspace with Shadow Prove by Keith and Mira, and is forced to battle. She no longer serves Zenoheld and has named herself a free agent. She loses to Mira and her mechanical Bakugan is destroyed. In the end, she rejects the Brawlers' offer to join them and instead throws a dimensional grenade at Keith and Mira. But after the grenade activated, Bakugan Interspace shut down, trapping her, Shadow Prove, Keith, and Mira inside. Marucho made a connection to bring them back, so Mira told Mylene and Shadow to come, but Mylene refuses to go. Mylene than got pull by the dimensional pull until Mira and Keith grabbed her hand, but accidentally let go her as Mira and Keith were teleported and Shadow grabbed Mylene's hand as they both were pulled in the dimensional portal. Her fate is unknown.

  Shadow Prove

Voiced by: Daisuke Endou (Japanese), Darren Frost (English)
Shadow is a Darkus brawler. He is very childish and jester-like. When he starts a battle, he is very pompous. His Guardian Bakugan is Darkus Hades, who was created with Alpha Hydranoid's DNA, and he also has Dakus Fortress as a Trap Bakugan. Mylene described him as a child in episode 3, and then a hyena in episode 15. He has the ability to copy other people's voices as he tricked Ace and Marucho into falling for a trap by being the voice of Mira and Dan respectively. He has a habit of sticking his tongue out every time he talks or laughs. He defeated Shun in episode 15. In episode 20 he and Mylene battled Dan and Baron in Beta City and were defeated when Drago unleashed the power of the Perfect Core. He later flees to Vestal with the Vexos, Prince Hydron, and Professor Clay, leaving Spectra and Gus. But soon after, he is forced to leave Vestal with the other Vexos after the citizens of Vestal rally against Zenoheld and Hydron. Later when Spectra blocks the Vexos from teleporting to Vestal, Zenoheld sends Shadow to Earth to battle Alice to learn the Brawlers back to Earth. Shadow does stalk her disguised as a werewolf before she battles him. He loses his Darkus Hades against Alice and Chan Lee, but reveals his mechanical Bakugan Darkus MAC Spyder, and wins easily. In episode 35, he joins with Prince Hydron to battle Marucho for the Aquos attribute energy and succeeds upon defeating Elfin, but lost to Preyas. When the Resistance infiltrated the Mother Palace, Shadow and Lync fought Ace and Marucho, winning the battle and taking the Darkus energy. He is trapped in Bakugan Interspace along with Mylene, Keith and Mira. Shadow and Mylene are pulled into the dimensional portal while Mira and Keith were teleported back to Earth. Because of staying behind with Mylene, it could be guessed Shadow has an attraction towards her. His fate is unknown.

• Hades

Shadow's first Mechanical Bakugan that resembles Alpha Hydranoid. Hades is a Mechanical Hydra-like Bakugan who lives to serve the Vexos. His primary weakness is that he needs to recharge after using strong attacks. He is Shadow's primary brawler when battling the Resistance. Hades has three fire breathing heads and six wings making him one of the fastest flying Bakugans. His three tails each have a spiky tip, so Hades can attack his opponent from many different directions. His metal exoskeleton can sustain multiple blows from any brawler, but on top of that, he has three large metal thorns that further protect his heart from attack.Alpha Hydranoid was the Bakugan he was based on.

• Fortress

Shadow's Mechanical Bakugan Trap. He is shaped like a rounded cube. He resembles a war robot. He can shower down lasers with his 'Proton Rain' ability.

  Volt Luster

Voiced by: Tomoaki Maeno (Japanese), Carter Hayden (English)
Volt is a Haos attribute brawler. He used Haos Brontes as his Guardian Bakugan and Haos Dynamo as a Trap Bakugan. He and Lync Volan are the Vexos' tag team champions, although they do not get along well together. He gets defeated by Dan in Invasion of the Vestals, and then again in episode 9 by Ace and Shun in the Bakugan Battle Tournament. He defeats Marucho in episode 14. He is defeated by Baron in Wall To Wall Brawl, and in Ultimate Bakugan is shown with Mylene and Shadow as they hatched an escape plan. In Final Countdown, his Haos Brontes was thrown out by Mylene, together with her Aquos Elico, as she thinks that Bakugan with feelings are useless. Although he was furious, he still left without Brontes, proving Mira's theory that he is brainless. He later flees to Vestal with the Vexos, Prince Hydron, and Professor Clay, leaving Spectra and Gus. He makes his reappearance in Spectra Rises, at first challenging Dan and the brawlers still in possession of Elemental Energies, but backs when Spectra appears, and Gus taunts him by saying he stole Brontes' soul. It is shown Volt seems to believe in doing the honorable thing, saying, "I won't kick a man when he's down," after Dan defeats Spectra, and seemingly weakened by the battle. Later, Volt challenges Gus to a brawl to win Brontes back, revealing his mechanical Bakugan Haos Boriates. However, he is defeated by Gus. In Samurai Showdown, Volt challenges Shun for the Ventus attribute energy. But Volt is defeated by the combined efforts of Shun and Baron. In Volt's Revolt Volt does not agree with King Zenoheld's plan to destroy all living things that stand up against him and returns home showing some of his past to the audience in the process. He is shortly thereafter confronted and challenged by Prince Hydron, Volt wins the ensuing Brawl then starts to leave not before scarring Hydron by telling Boriates to nearly crush him. As payback, Hydron throws a grenade in front of Volt, which opens a dimensional port beneath him, sending him into a far dimension. As Volt sinks into the portal, he vows that Hydron will get what's coming to him for all the suffering he has caused innocent people. Volt later appears in Hydron's dreams/hallucinations along with Lync in An Heir To Spare. His fate is unknown.

• Alto Brontes

Alto Brontes evolved from Brontes when Gus used the Forbidden Card on him. He has become mean spirited and gains more energy from defeated Bakugan.

Dynamo uses his large pincers to grasp and thrash opponents around, and his six legs make him extremely maneuverable. He also links with Boriates with his Battle Arm Mode.

• Hexstar (Carlvelt)

Volt's second Mechanical Bakugan Trap, a robotic version of Baliton. It walks on all four of its legs and is one of the strongest Bakugan. The spikes covering its back provides ultimate protection.

Lync is a Ventus brawler. He used mechanical Ventus Altair as his Guardian Bakugan, and mechanical Ventus Wired as a Trap Bakugan. Altair and Wired are able to combine into Meta Altair. However, in Gate Crashers, Altair and Wired were damaged beyond repair, and did not brawl for the rest of the arc. He was a spy for Prince Hydron on Spectra and Gus. He and Volt Luster were the Vexos' tag team champions. He gets defeated by Dan in Invasion of the Vestals, and then again in episode 9 by Ace and Shun in the Bakugan Battle Tournament. He then gets defeated by Baron in episode 11. He went to Earth with Spectra, Gus, Dan, Mira, and Baron. He was stuck on Earth with Alice after rejecting Dan's hospitality. He is seen crying at the end of episode 11. Baron called him 'a little weasel' in episode 11. In the same episode, Gus calls him a snake. He has his Gauntlet taken away by Dr. Gehabich in order to fix his dimension transporter without Lync realizing it (although it would not have mattered, as his Bakugan were destroyed anyhow). Lync eventually makes it home after swearing loyalty to Spectra and when Prince Hydron asked him to spy on Spectra, Lync denies him and helps Spectra with his "ultimate plan". But he then betrays Spectra by locking up Gus so he cannot tell his master of Mylene's escape plan. It is obvious he will do whatever is best for him (going as far as to claim behind Hydron's back "You can count on me to do what's best for me." He later openly admits that he's "very loyal to three people: me, myself and I" in conversation with Volt and the other Vexos), due to his multiple betrayals throughout the series. He later flees to Vestal with the Vexos, Prince Hydron, and Professor Clay, leaving Spectra and Gus. He reappears to battle Shun after Zenoheld launches a prototype for the Bakugan Termination System, but is defeated with the combined efforts of Skyress, and a newly evolved Ingram. In Earth Invaders, Lync and Mylene battle Runo and Mira and succeed in obtaining the Subterra attribute energy. He later brawls Ace and Marucho alongside Shadow, taking the Darkus energy. Lync does like Alice, or so it seems. It was this that finally caused him to leave the Vexos when Zenoheld declared that the alternative would be used to wipe out Vestal, Earth, New Vestroia (may have been a likely target as Zenoheld had a grudge against the Bakguan, although it was not mentioned in the list of targets) and anyone else that opposed him. After Volt's departure and "demise" at Hydron's hand, Lync copied the Blue Prints of the alternative to give to Alice (who would warn the resistance). He hesitates to speak to her, feeling guilty about his betrayal of her trust. However he resolves to speak to her. However Hydron appears on the scene (Professor Clay had discovered that Lync had made an unauthorised copy, which Mylene overheard him saying, she reported the incident to Zenoheld, who sent Hydron after Lync) and challenges him to a battle. Lync puts up a heroic and close fight but Aluze is destroyed by Dryoid and he is banished with a death bomb by Hydron (but not before throwing his glove with the data disk towards Alice's home, where she found it later outside, once the battle and its combantants had disappeared from the secene). Lync later appears in Hydron's dreams/hallucinations along with Volt in An Heir To Spare. His fate is unknown.

• Altair

Altair is used mostly by Lync to battle the Resistance. Altair is the first Mechanical Bakugan. The lenses in its red eyes glimmer brightly to see at night. Its fangs and horns are sharp as swords. The wide spread wings have turbines to hover and white steam shoots from his mouth. It possesses a fierce battle cry that deafens its opponents. The huge mechanical monster was created by Professor Clay.

• Wired

Lync's Mechanical Bakugan Trap. He is shaped like a ridged sphere. He resembles a "small" mechanical bird. He can make it shower acid-like energy with his 'Shower Harpoon' ability. Wired also combines with Altair into Meta Altair. They both were burned out by Nemus in Gate Crashers.

• Aluze

Lync's second Mechanical Bakugan after Altair was burned out. He is a Cybernetic Bakugan. He is similar to Altair. He was destroyed in Payback by Hydron and was destroyed in the same place Altair was destroyed.

  Twelve Orders

  Barodius / Mag Mel

Voiced by: Ken Narita (Japanese), Shawn Meunier (English)
The central villain of the third season, and also a major villain in the fourth season (alongside Wiseman). The Emperor of Gundalia, leader of the Twelve Orders and also a Darkus Brawler. He was born to a family that has ruled Gundalia for a long time. He is the leader of the Twelve Orders that seek to conquer Neathia. He has been able to rule Gundalia due to his overwhelming strength and special ability to simultaneously execute battles. His sole desires are: to obtain the secret DNA Code from the Bakugan that possess it and create the most powerful Bakugan in the universe. His other goal is to take Neathia's Sacred Orb so he can rule the universe. His Bakugan partner is Dharak. Gill is his longtime childhood friend and most trusted confidant, but when Barodius found out that Gill killed Kazarina, he had Phantom Dharak destroy both Gill, Airzel, Stoica and their Bakugan. His quiet and calm demeanour masks his hot tempered and devious nature. He is highly arrogant but also highly intelligent. Barodius and Phantom Dharak have a final showdown with Dan and Drago and in the end, they lost to Dan and Drago. Refusing to admit defeat, Barodius and Phantom Dharak start to take the power of the Sacred Orb only for Code Eve to banish them inside a flip world of Bakugan Interspace, thus turning them into Mag Mel and Razenoid, although the Brawlers at first believed that the two had been killed after Dharak absorbed too much of the Sacred Orb's powers. Now he keeps his desire to take the Gate and Key to control the Mechtogan and Bakugan in existence.

  Kazarina

Voiced by: Linda Ballantyne
Member of the Twelve Orders. She's a Haos Brawler. She is sly as she is cold-hearted and is always by Emperor Barodius' side. She works as the Director of the Bakugan Biological Research Center, where she secretly undergoes cruel living body experiments to heighten the abilities of Bakugan. Her goal is to develop abilities that will rival the Neathians. She is an exceptional scientist who has unraveled the mysteries of Bakugan evolution. She can also hypnotize others to do her bidding, as shown with Jake and Coredem. She is heartless and selfish, as she would sacrifice one of her own subordinates to use as a scapegoat without losing any sleep on it. Another example of her cruelty was shown in a battle before the series began, when she killed a number of Neathian soldiers, including the previous commander of the Castle Knights and Fabia's fiance Jin before capturing Aranaut and sadistically experimenting on him. Her Bakugan partner is Lumagrowl. Kazarina gets killed by Gill in the middle of Broken Spell and her spell on everybody is broken. When Lumagrowl hears about Kazarina's death, he leaves in sadness. His final, mournful howl over her death is heard echoing.

• Lumagrowl

Kazarina's Guardian Bakugan. Resembles a six-tailed Kitsune/wolf hybrid. His Battle Gear is Barias Gear.

  Gill

Voiced by: Scott Gorman
Member of the Twelve Orders. He's a Pyrus Brawler. Gill is a calm, cool warrior who pledges his undying loyalty to Emperor Barodius. He had no parents when he was a child and was raised by the Emperor's family, seeing Barodius as an older brother. He will follow Barodius' orders without considering whether it is right or wrong. He is a teacher and trainer of Airzel, who shares a Spectra-Gus relationship with him. This relationship is also shown between him and Barodius, with Barodius in the "Spectra" role and Gill in the "Gus" role (reverse of his relationship with Airzel). It is shown that many times in the series he distrusts Kazarina, and he shares a mutual hatred with her, as well as fighting over Barodius's favor. His Bakugan is Krakix. He first appears in Revelation, where he and the rest of the Twelve Orders discuss on how powerful Drago truly is. In The Secret Package, he, Airzel, and Kazarina join their brainwashed battlers against the Neathian Castle Knights. In The Element, Gill reports to Emperor Barodius that their Gundalian forces took down the second shield and Neathia's front line. In The Sacred Orb, Gill and Krakix battle against Captain Elright and Raptorix, but as Drago and Dharak come face to face, the Sacred Orb teleports the Twelve Orders back to Gundalia. In Battle For the Second Shield, before Lena leaves for Neathia with Kazarina, Gill tells her to watch her back around Kazarina, for she is loyal to no one but herself and would think of nothing of sacrificing one of her subordinates to save herself. After reporting to Barodius, she runs into Gill, letting him know of Lena's betrayal, suggesting that someone may have told her what she had planned for her. Gill replies that she got lucky today, and that you never know who you can trust. In Partners 'Til the End, Gill and Ren planned on going to Neathia to take down the second shield, but Zenet disguised herself as Ren to redeem herself. But when Krakix thumped Ren (Zenet) on the head, she morphed back to her normal self. As she begged for a second chance, Gill allowed her to accompany him on this mission. Krakix took out the Castle Knights guarding the second shield. Then, Gill had Krakix scan the shield so they could destroy it on a molecular level. But when Shun and Hawktor swooped down on them, Gill had Zenet delay him while Krakix scanned the shield. But as Contestir was about to shoot down Hawktor, he tricked him and Zenet into hitting Krakix. Gill jumped in and as he was about to finish Shun and Hawktor, Dan and Drago arrived on the scene just in time. With the combined teamwork between Dan and Shun, Gill and Zenet lost and retreated. Because of the Brawlers' interference, they were only able to transfer 76% of data from the shield. Just as Gill was about to punish Zenet, Contest spoke up for her and suggested to Gill that he should have someone loyal only to him, to keep an eye on the other members of the Twelve Orders, and volunteered Zenet for the role. Convinced, Gill decides to try it out, so he has Zenet disguise herself as Nurzak to spy on Kazarina for him. Zenet reports back to Gill with information on Kazarina and Nurzak plotting to overthrow Barodius. Despite their excellent job, Gill and Krakix dispose of Zenet and Contestir, as they saw no further use for them.
In Divide and Conquer, Gill informs Barodius of Nurzak and Kazarina's plot against him. As Gill volunteered to do away with these traitors, Barodius told him otherwise and that this information does not leave his room. Furious at Kazarina, Gill vows to take her down, one way or another. In Mobile Assault Dharak suggests that they keep the Neathians busy with a wave of attacks of brainwashed battlers. He, Stoica, and Airzel lead the attack against the Neathians. With 72% of Gundalian forces down, Gill orders the first battalion to fall back and the second to prepare to attack. He then asks Kazarina to resupply him more battlers from Earth, so she has Ren go do it, and Gill has Stoica tag along with him. In Colossus Dharak, as Stoica battles Marucho and Jake, Gill steps in for support. In Dragonoid Colossus, Gill and Jake battle each other, both using their Battle Gear, but Krakix's Vicer proves to be stronger. When Linehalt unleashes his Forbidden Power, the Twelve Orders retreat back to Neathia. In Into the Storm, Gill and Krakix defeat the Castle Knights and attack the third shield, but unfortunately, the third shield has a DNA barrier, preventing Gundalians from passing through the shield. He then retreats back to Gundalia and reports his findings back to Emperor Barodius. In Infiltrated, Barodius orders Gill and Airzel to separate Dan from Marucho and Shun. Gill and Airzel begin to battle Marucho and Shun, who have fallen for their trap. When Gill is prepared to take on Shun, he surprises him by finishing off Airzel, but Gill defeats both Marucho and Shun. Before Gill and Airzel can take them away, Shun throws down a smoke ball, letting Shun and Marucho escape. In Final Strike, Kazarina informs Barodius that Drago's DNA can be spliced with Dharak's DNA so Dharak can evolve, in which Gill protests against it, for risking their greatest weapon, the Emperor's weapon, is too great a risk. But Emperor Barodius orders him to stand down. After Dharak evolves, Barodius promotes Kazarina to his #2, infuriating a demoted Gill. Barodius then orders him to come with him. After the Brawlers break into the castle, Barodius has Gill take care of them while he heads to Neathia with Lena, Zenet, and Jesse (who are brainwashed). Once in the castle, the Brawlers run into Gill. Krakix attacks them before they can even launch their Bakugan, leaving them vulnerable. Fortunately, Ren and Linehalt counters Gill's attack before it hits the Brawlers. The Brawlers then leave Gill to Ren.
In Dream Escape, Ren leaves the battle to join Dan, Fabia, and Jake, but Gill follows him as well. As the Twelve Orders reunite, they prepare to attack the Brawlers. In Gundalian Showdown, Gill, Kazarina, Stoica, and Airzel battle against the Brawlers. Just as it seems that Gill has defeated Drago, he comes out unscratched. Drago defeats him with Spire Dragon, as well as Stoica and Airzel, but not Kazarina. After the Brawlers leave for Neathia, Gill orders Stoica and Airzel to follow them. He did not go because "his ship was damaged by the Brawlers". In Broken Spell, Kazarina, looking for her sword, finds Gill, holding her sword. Gill says they need to talk about things, but Kazarina just scolds him to stay in his place. Then Gill, using Kazarina's sword, kills Kazarina, telling her to watch what she says, for words have consequences. In Code Eve, Gill and Krakix, having spotted Fabia, Nurzak, and Mason, try to keep them from returning to Neathia, but they escape on Nurzak's ship. Just as he makes it to Neathia, Gill apologizes to Emperor Barodius for being late and tells him that Kazarina was taken down in battle by Fabia. But Barodius knows it was him who finished off Kazarina. For his betrayal, Barodius has Phantom Dharak attack Gill, along with Airzel and Strikeflier, who try to protect him, but are all killed.

• Krakix

Gill's Guardian Bakugan. Resembles a samurai. His Battle Gear is Vicer.

Airzel

Voiced by: Lyon Smith
Member of the Twelve Orders. He's a Ventus Brawler. Emperor Barodius and Gill recruited Airzel to be a warrior, and Airzel continues his battle training with Gill. He lurks in the shadows, to protect Barodius who chose him personally to be part of the 'Twelve Orders'. Airzel is the leading expert in enemy surveillance and information analysis. He always takes matters seriously, which causes him to be annoyed by Stocia's laid-back personality. Airzel is the #1 trainer on the Special Bakugan Team. His Bakugan partner is Strikeflier. He is fierce, confident, and reckless. He first appears in Revelation, where he and the rest of the Twelve Orders discuss on how powerful Drago truly is. In The Secret Package, he, Gill, and Kazarina join the brainwashed battlers from Earth against the Neathian Castle Knights. After sending Linus to Earth with the Element, Elright is confronted by Airzel, asking him where the Element is. In The Element, Airzel reports to Emperor Barodius that they had captured Captain Elright, but his interrogation has not been successful. In The Sacred Orb, Airzel battles against Shun, and having blended in with the surroundings, gained the upper hand. Just as Drago and Dharak are about to face each other, the Sacred Orb teleports the Twelve Orders back to Gundalia. In Decoy Unit, Airzel volunteers to attack Neathia and take down the third shield, taking Mason with him too, as a chance to redeem himself. With their Gundalian forces and battlers from Earth, Airzel and Mason battle against Marucho and Jake. When the battle gets intense, Marucho and Akwimos trap Strikeflier and Avior in a block of ice, with Marucho and Jake escaping Airzel and Mason. In Mobile Assault, Gill, Stoica, and Airzel lead a front line of brainwashed battlers against the Neathians. In Colossus Dharak, Airzel and Strikeflier battle Shun and Hawktor, but when Fabia intervenes, Kazarina steps in to help Airzel. In Dragonoid Colossus, Airzel and Shun continue their battle, both using Battle Gear. Just as Hawktor takes out Lumagrowl, Strikeflier sneaks up on him and Shun and finish them off. When Linehalt unleashes his Forbidden Power, the Twelve Orders retreat back to Gundalia. In Infiltrated, Emperor Barodius orders Gill and Airzel to separate Dan from Marucho and Shun. Gill and Airzel begin to battle Marucho and Shun, who have fallen for their trap. When Gill is prepared to take on Hawktor, he finishes off Airzel, but Gill defeats both Marucho and Shun. Before Gill and Airzel can take them away, Shun throws down a smoke ball, letting Shun and Marucho escape. In Final Strike, Airzel takes on Marucho as the Brawlers make their way to Dan. In Gundalian Showdown, Gill, Kazarina, Stoica, and Airzel battle the Brawlers to keep them from leaving Gundalia, but are all defeated by Drago's Spire Dragon, all but Kazarina. Just as the Brawlers take their leave, Stoica and Airzel prepare to leave for Neathia, but when Stoica wonders where Gill is, Airzel tells him that the Brawlers damaged his ship and told them to go on ahead. In Broken Spell, Stoica and Airzel reach Neathia, keeping Dan and Shun away from Barodius. After Kazarina's spell breaks, Stoica reveals that on the way to his ship, he saw Airzel and Gill talking about Kazarina. Airzel admits to Stoica that it was Gill that killed Kazarina, not Fabia, with Barodius listening in on them, thanks to Stoica's speakerphone being on. In Code Eve, Airzel realizes that Barodius was listening in on his conversation with Stoica, who had his speakerphone on. Just as Dharak perpares to attack Gill, Airzel and Strikeflier fly to his ship to protect him, but are killed along with Gill by Dharak's attack.

• Strikeflier

Airzel's Guardian Bakugan. Resembles a winged samurai. He also possess' the ability to use his enemies attacks. His Battle Gear is Battle Turbine.

Stoica

Voiced by: Mike Kiss
Member of the Twelve Orders. He's an Aquos Brawler. He has a split personality: one of an angel, the other the devil, which can change in a second, so turning your back on him is a very bad idea. Stoica is usually calm and pompous, but when he is irritated, he will need a lot to calm him down. Stoica has lots of trick moves during battle and opponents have a hard time reading him. He has saved Gundalia many times with ingenious battling abilities. He is the youngest member of the Twelve Orders. His Bakugan partner is Lythirus. He is the only member of the Twelve Orders to show his human form. He first appears in Revelation, where he and the rest of the Twelve Orders discuss on how powerful Drago truly is. In The Sacred Orb, Stoica and Lythirius battle Marucho and Akwimos in the water. Just as Drago and Dharak are about to face each other, the Sacred Orb teleports the Twelve Orders back to Gundalia. In The Secret Switch, Stoica and Jesse find Dan, Shun, and Fabia in the jungle, wondering why they are even there in the first place. As Shun flees the scene, Stoica lets Jesse and Plitheon take on Fabia and Aranaut, but loses to them. Anxious and impatient, Stoica and Lythirius enter the battle. As he keeps taunting Dan, Stoica realizes that Dan and Shun switched Drago and Hawktor around. Even with Razoid, Stoica and Jesse both lose to Dan and Fabia. In Curtain Call, as he and Kazarina try to blame each other for loss of the second shield, Stoica suggests they blame Jesse for their mistakes. Unfortunately, Jesse has escaped, so he sends Ren to go retrieve him. After losing to Fabia and Jake, Ren returns to Gundalia with Jesse for Kazarina and Stoica. Just as they are about to dispose of Jesse, Plitheon speaks out of wanting to leave Jesse. However, Lumagrowl and Lythirius subdue Plitheon for turning on his partner. After disposing of Plitheon, Kazarina and Stoica do the same with Jesse. While walking down the hall, planning their report for Barodius, Kazarina and Stoica run into Nurzak, who tells them that they may be able to fool the others, he can see them for who they really are. In Mobile Assault, Gill, Stoica, and Airzel lead a front line of brainwashed battlers against the Neathians. Then, Gill has Stoica go to Earth to recruit more battlers from Earth. In Bakugan Interspace, Stoica and Ren, in their human forms, go to recruit new battlers, but Stoica leaves Ren to do the recruiting, while he goes searching for battlers in Bayview City. He then follows Koji, a battler, and persuades him into coming with him to Gundalia, so Kazarina can brainwash him (Koji having no clue of Stoica's intentions, merely that he was going to get a chance to have a brawl). In Colossus Dharak, Stoica takes on Marucho and Jake, but Gill steps in. In Dragonoid Colossus, Stoica is seen battling against Marucho, with both Lythirius and Akwimos using their Battle Gears. Thanks to Razoid, Stoica and Lythirius beat Marucho and Akwimos. Then, just as Linehalt unleashes his Forbidden Power, the Twelve Orders retreat back to Gundalia. In Redemption, Kazarina and Stoica confront Fabia and Nurzak and engage in battle with them. As Kazarina and Stoica press on the attack with their Battle Gears, the ground under Fabia and Nurzak crumble, with them falling. They then find Fabia and Nurzak to survive their fall, thus continuing their battle. Just as they have got the upper hand, Stoica has Lythirius flood the battlefield, forcing Kazarina, Lena, Zenet, and Jesse (the last three being brainwashed) to retreat. With Fabia and Nurzak to himself, Stoica, now underwater, blasts them, sending Nurzak down the current. In Final Strike, Stoica and Lythirius knock Shun, Hawktor and Fabia to the ground as they are trying to reach Dan's location. Fabia leaves Stoica to Shun. In Gundalian Showdown, Gill, Kazarina, Stoica, and Airzel battle the Brawlers to keep them from leaving Gundalia, but are all defeated by Drago's Spire Dragon, all but Kazarina. Just as the Brawlers take their leave, Stoica and Airzel prepare to leave for Neathia, but Stoica stops to wonder where Gill is. Airzel tells him that his "ship was damaged when the Brawlers attacked and said to go on ahead", making Stoica suspicious. In Broken Spell, Stoica and Airzel reach Neathia, keeping Dan and Shun away from Barodius. After Kazarina's spell breaks, Stoica reveals that on the way to his ship, he saw Airzel and Gill talking about Kazarina. Airzel admits to Stoica that it was Gill that killed Kazarina, not Fabia, with Barodius listening in on them, thanks to Stoica's speakerphone being on. In Code Eve, Airzel realizes that Barodius was listening in on his conversation with Stoica, who had his speakerphone on. Stoica and Lythirius attack Dragonoid Colossus with acid bubbles in his eyes, blinding him in the process. But Dharak attacks Dragonoid Colossus with Stoica and Lythirius still on him, killing them all.

Mechtogan Army Faction

Coredegon / Wiseman

Voiced by: Rob Tinkler(Wiseman), Tyrone Savage (Coredegon)
The main villain that made debut in the 2nd arc of Mechtanium Surge, after Mag Mel was defeated. Originally a Mechtogan created in the Doom Dimension by a Nonet Bakugan called Fury, Coredegon destroyed his creator and said that he is a Mechtogan with his own free will and he wants to destroy all Bakugan and create an army of Mechtogan. He then arrived in Bakugan City and brought an army of evil Mechtogan to attack and take over Earth. Coredegon then became Mechtavius Destroyer along with his pals Exostriker, Mandibor, and Slycerak, but he was later defeated by Dragonoid Destroyer. However, Coredegon kidnapped Gunz and absorbed his energy to copy his human form and mannerisms, starting to call himself "Wiseman". He also knows the story about the original Dragonoid and how Drago is its descendant.
He freed the Nonet Bakugan from the Doom Dimension and tricked them into helping him re-summon Mechtavius Destroyer so he could defeat the Battle Brawlers. He ended up getting defeated when Dragonoid Destroyer was summoned and helped Jaakor and Reptak boost their power. In Mysterious Bond, he fought Dan Kuso using Betadron, Kodokor and Mutabrid and formed Gliderak. Even though he defeated Drago and Reptak's Bakugan Battle Suits, he lost when Reptak and Drago formed Aeroblitz. In The Prodigal Bakugan, he fought Shun and Jaakor as well as Orbeum and Skytruss using Spatterix and Stronk. In Combination Impossible, he used Balista and Worton against Radizen. In Enemy Allies, he summoned Coredegon and the other Mechtogan to fight the Battle Brawlers but ended up losing. In Battle for Bakugan Land, he fought Dan using Scorptak. He was winning until Dan used Drago and Reptak's Battle Suits, and Dan won the battle. In Gunz Blazing, he disguised as Gunz Lazar to confuse the Brawlers that he is Gunz. He stole some Battle Suits Data. He battles Dan with his Haos Tremblar. He wins the first round against Reptak, but loses from Dragonoid Destroyer and Reptak in the next round. In Battle Suit Bash, he fought the brawlers using Betadron, Kodokor, and Mutabrid using the stolen Battle Suits Clawbruk, Fortatron, and Combustoid. It was revealed in the end of the episode that he isn't Gunz. He's a mysterious being who stole Gunz's appearance and battling style. In Countdown to Doomsday, he battle the brawlers once more in a huge battle with all the Nonets and combinations with them. Later in the battle, he summons Coredegon, Slycerak, Exostriker, and Mandibor to combine into Mechtavius Destroyer and wins the battle for the first time against the Battle Brawlers. In End Of The Line Coredegon,Slycerrak,Exostricker,and Mandibor later died by Drago and Dragonoid Destroyer.

Legendary Soldiers

They are Bakugan who defeated an army of Gargonoids long ago. Since then, they have become legends and preside over Vestroia from the Doom Dimension. There is one of each Attribute. When the Battle Brawlers came to the Doom Dimension they were met by the Soldiers and a deal was struck, if all of the Brawlers could defeat the soldier that uses the same attribute as them they would take them out of the Doom Dimension and take all of the Bakugan that Masquerade and his minions sent there. They all won, so the Soldiers had to keep their end of the bargain. In New Vestroia, the Soldiers reappear conversing with Drago and giving him a body, transforming him into Neo Dragonoid, and sending him to the human world to get Dan. Then Vestroia starts to collapse without him and all they can do is wait and discuss. After Drago returns to New Vestroia the Perfect Core becomes stable again and they later appeared to send Drago and the others to Earth. The Six Ancient Warriors then battled Zenoheld after he threatened to destroy the Bakugan if they did not come. Although they had the upper hand, the tide of the battle turned quickly after Zenoheld unleashed the Assail System. They were defeated, but before they could lose their attribute energies they transferred their power to the Resistance' Bakugan, thus giving up their lives.

• Apollonir

Voiced by: Zachary Bennett

He is the legendary Bakugan that resembles a dragon with four sets of wings and humanoid posture. He is the Leader of The Six Legendary Bakugan. In battle, Apollonir is the most powerful Dragonoid Bakugan. Apollonir was the most powerful Dragonoid. He was with a clown who used two Mock Dragonoid to battle against Dan and Drago. When Drago defeated the two Dragonoids, Apollonir left his disguise and prepared to battle Drago. Dan used the ability D-Strike Extreme and repeatedly did that until Drago defeated him. But when Drago still didn't evolve, he explained that he needed to defeat all of his friends to further evolve. In the first season, his wings resembled leathery insect wings. When Drago was taken by Spectra while on Earth, Apollonir appeared to Dan in a dream and offered to temporarily become Dan's Guardian Bakugan. During the battle against Spectra, Apollonir easily defeated Helios, but when Drago arrived, he and Dan were backed into a corner, and Dan used Dragon Proudia, turning Apollonir into a trident. Dan then proceeded to throw him, hitting Drago's Perfect Core diamond and freeing him from Spectra's command. Also, Apollonir is revealed to be linked to the Perfect Core, just like Drago, and as such, he has the ability to detect Drago from anywhere on New Vestroia. In Reunion, when Drago says that he can no longer leave New Vestroia due to his link with the Perfect Core, Apollonir explains to Drago that though he is linked to the Perfect Core, he had become strong enough to free himself from it. Apollonir gave his Attribute Energy to Drago just like the other Legendary Soldiers did to the Bakugan belonging to the Resistance. This forced Drago to evolve into Cross Dragonoid. Apollonir's wings now resemble Helix Drago's wings.

• Lars Lion

Voiced by: Julie Lemieux

Legendary Haos Bakugan that resembles an angel-like warrior, Lars Lion is an extremely moral member of The Six Legendary Bakugan. A knight’s armor protects her head and body. She uses the golden arrow weapon to bring back defeated Haos soldiers. She was the one who tested Runo. She was originally disguised as an old woman who told Runo where an Illusionary Dan was the person she chose to Brawl Runo was. When she revealed herself, she outright told Runo to stop being so stubborn, but Runo would not listen. She almost won using the most powerful Haos ability card, Sagittarius Arrow. This revives all Bakugan used in the battle that can side with her and uses them to boost her power. She has a basic power level 500 Gs. She was defeated after Runo learned to stop being so stubborn and to listen to her friends, (in the Japanese version, she admitted she loved Dan), and Tigrerra evolved into Blade Tigrerra and used Velocity Fang ability to disable Sagittarius Arrow, lowering Lars Lion's power level by 100 Gs and winning the battle. During Lars Lion's and Runo's battle they don't get to see who wins because when the battle is almost over Lars Lion says that Runo has learned not to be stubborn. A noticeable fact is that Lars Lion's battle form is basically the same as her masked form except Lars Lion wears a mask in her masked form while observing Runo's battle against the fake young Dan. Lars Lion gave her Haos Energy to Mega Nemus, which forced Nemus to evolve into Saint Nemus.

This made Marucho realize that he needed to accept how his past allowed him to become who he is today and Marucho gained Preyas II.

In her masked form, she takes the form of a maiden in green clothing. Oberus battles Shun in 'A Place Far From Home' under the control of a younger version of Shun's mother. This caught Shun very off guard and upset him very much due to his mother's current state and how happy this version was. She uses the ultimate Ventus ability card, Turmoil, to boost her power level of 500 Gs to 700 Gs but can only defeat one Bakugan in return for this massive power boost. She was defeated after Skyress evolved into Storm Skyress and used the 'Destruction Meteor Storm' ability card to boost her power by 200 Gs. Oberus gave her Ventus Energy to Ingram, which forced Ingram to evolve into Master Ingram.

He then subdued Linehalt, thus ceasing the Forbidden Power. After that, he then entered an unconscious Dan's BakuMeter. In "Genesis", Dragonoid Colossus teleports Dan and Drago to a place in between dimensions. In order to return to Neathia, Dan and Drago must battle Dragonoid Colossus.

Nurzak

Voiced by: Hadley Kay
A former member of the Twelve Orders who is a Subterra Brawler, and the oldest Gundalian living, as he served Barodius's father (the previous Emperor). He is a scholarly and wise intellectual. Despite being the oldest of the Twelve Orders, he has the most physical energy. He is the #1 officer of the Twelve Orders and is very good at analyzing the opponent, planning strategy and evaluating the situation. His Bakugan partner is Sabator. He first appeared in Revelation, where he and the rest of the Twelve Orders discuss how Drago truly is. In The Sacred Orb, Nurzak and Sabator battle against Jake and Coredem, both Bakugan evenly matched, but when Drago and Dharak come face to face, the Twelve Orders are teleported back to Gundalia. In Curtain Call, Nurzak runs into Kazarina and Stoica as they plan their report, telling them that he is not fooled by their act like the others, for he can see them for who they really are. In The Secret of the Orb, Kazarina and Nurzak are ordered to lead a reconisis mission on Neathia, and take Ren and Mason with them. Nurzak speaks of the Sacred Orb and of its power, saying that it is too dangerous to anyone who doesnot fully understand it's power, for that is the reason why Emperor Barodius' father chose to leave it alone, for he feared that the Orb would bring destruction to anyone possessing it. After Mason escapes from Kazarina, Nurzak assures her that he and Ren will go retrieve Mason for her. While searching for Mason, Nurzak and Ren run into Fabia and Marucho and begin to battle. Nurzak steps into the battle after Marucho gains the upper hand over Ren. When all four battlers use their Battle Gears against each other, the battlefield begins to tear apart, and the Sacred Orb sends a dimensional twister towards them. Nurzak says that the Sacred Orb is sending them a warning, and decides to retreat back to Gundalia, for they should not anger the Sacred Orb. After being severely punished by Barodius, Kazarina walks into Nurzak, who apologizes to her for not getting Mason. But what he really wants to tell her is that he's leaving Barodius, and suggests that with Gill as Barodius' #1, she should find a place for herself. So she joins Nurzak in leaving Barodius. In Divide and Conquer, Nurzak sends a transmission to Neathia. He asks the Brawlers to meet with him to discuss a peace treaty, sunrise tomorrow, at the western edge of Sector K. Nurzak then speaks with Kazarina, who tells him of her control over half of the Gundalian soldiers, for when the time is right, she will give the signal and they will have an army ready to overthrow Barodius. Nurzak tells her that they will strike tomorrow, when the bells ring at dawn, and that Kazarina will lead the attack forces against Barodius by herself. With Kazarina leading the revolt, Nurzak will use it as a smokescreen as he escapes to Neathia. He wishes to give a peace offering to the Sacred Orb, which contains the Switch Code, for anyone hoping to harness the Sacred Orb, must be in possession of it. Barodius' father gave it to Nurzak for safe keeping, for both he and Nurzak fears the powers of the Sacred Orb, unlike Barodius. Readying himself to prepare with Kazarina, Nurzak runs into Ren, who gives Nurzak hope that Gundalia will be better than they ever dreamed. Nurzak then opens a secret doorway, leading to the ancient catacombs tunnels, which he will use as an escape route, but is stopped by Barodius before leaving. Just as the bells ring, Kazarina and her attack force teleport to Nurzak and Barodius, but betrays Nurzak for Barodius, for he had her spy on Nurzak. Barodius decides to deal with Nurzak via battle. When Nurzak has Sabator absorb Dharak's Darkus powers, it proves too much for him. But when Dharak unleashes the power of his Battle Gear, AirKor, it destroys the entire building and all the Gundalian soldiers in it, and both Nurzak and Sabator were caught in the blast, with only Barodius and Kazarina surviving the battle. In Genesis, Dan and Drago are teleported to the space between dimensions by Dragonoid Colossus, where they find Nurzak and Mason there too. It turns out that when Nurzak and Sabator were blasted by Dharak, they were teleported to the space between dimensions. Nurzak and Mason cannont leave the space, but Dan and Drago have one chance: they must defeat Dragonoid Colossus. Nurzak explains that the Sacred Orb is the origin of all Bakugan and Dragonoid Colossus has been tasked with protecting the Orb. He also explains that the only two capable of defeating Dragonoid Colossus were the dragons of fire and darkness: Dragonoid and Dharaknoid. After defeating Dragonoid Colossus, Dan and Drago travel back to Neathia, bringing Nurzak and Mason with them. When Fabia questions Dan on whether Nurzak and Mason can be trusted, Nurzak pleads with her that he has no loyalty for Barodius and that he must be stopped. He also asks her if she will allow him to fight alongside her and the Brawlers to defeat Barodius and protect the Sacred Orb, and Mason volunteers to fight as well, in which she gives them the benefit of the doubt. The Brawlers, Nurzak, Mason, and Dragonoid Colossus then travel to Gundalia in a rescue attempt for Jake and Ren's teammates. In Infiltrated, Ren, Nurzak, Mason and Fabia decide to head towards Kazarina's Lab, in hopes of finding Lena, Zenet, and Jesse. In True Evolution, Nurzak suggests that he, Fabia, Ren, and Mason split up, for if Kazarina is expecting them, then they can attack her from two sides. So Fabia and Nurzak go one way, and Ren and Mason go the other way. As they are searching for Kazarina's Lab, Nurzak and Fabia are confronted by Kazarina and Stoica. In Redemption, Nurzak and Fabia battle against Kazarina and Stoica, but as Lumagrowl and Lythirius press on the attack with their Battle Gear, it destroys the ground below Nurzak and Fabia, causing them to fall. While hiding from Kazarina and Stoica, Nurzak tells a story about a friend (himself) of his led a platoon of warriors - including his own daughter - into battle they were unprepared for and were killed. He tells Fabia this because she reminds him of her. Then, they are spotted by Kazarina and Stoica. Kazarina then springs a surprise for them: a hypnotized Lena, Zenet, and Jesse. Then, Stoica has Lythirius flood the battlefield, forcing Kazarina, Lena, Zenet, and Jesse to retreat, leaving Nurzak and Fabia to himself, who are now underwater. Stoica then blasts them, which sends Fabia down the current, but Nurzak saves her, but he and Sabator are swept away by the current. As he's being washed away, Nurzak apologizes to his daughter, Floria, and tells her he will see her soon. In Gundalian Showdown, as Fabia is about to be attacked by Lumagrowl, Avior flies in to save her, with Mason and Nurzak, well and alive. In Broken Spell, Nurzak and Sabator step in the battle to help Fabia and Aranaut. Nurzak confronts Kazarina and tries to convince her that Barodius is only using her and only cares about the Sacred Orb, but she refuses to listen to him. Nurzak then knocks out Kazarina's sword to the ground, and Kazarina flees the battle to retrieve her sword. As Nurzak searches for Kazarina, he finds her dead body laying on the ground. He then brings her body out, distracting Lumagrowl, giving Aranuat the perfect chance to finish him. He does not know who killed her, but he has an idea of who. In Code Eve, as Fabia and Mason battle Gill, Nurzak prepares a Gundalian ship for Neathia, and then takes off with Fabia and Mason. As they arrive on the scene, Lena, Zenet, and Jesse are surprised to see Mason and Nurzak alive. As Barodius makes his way to the castle, Nurzak and Sabator stop him, in which Barodius is surprised to see him alive. As Sabator is about to strike down Barodius, Lythirius shoots him with acid bubbles, and Nurzak tries to finish Barodius off himself, but fails, and falls to the ground. In Destiny Revealed, just as Dan, Drago, Barodius, and Dharak return to the Sacred Orb Chamber, the Brawlers, Ren's teammates, the Castle Knights, Nurzak, and Queen Serena arrive on the scene. But Barodius and Dharak, refusing to admit defeat, go for the Sacred Orb, but are killed by its immense power, with the others looking away in fear. After the war is over, Nurzak plans to return to Gundalia to form a new government which will have friendly relations with Neathia, which Queen Serena permits. Nurzak, Ren, Lena, Mason, Zenet, and Jesse then teleport to their ships and return to Gundalia. In "Mechtanium Surge", he is now the first Prime Minister of Gundalia.

After Shun thinks his mom is dead the doctor says she is just tired which turned out to be true. After Shun's initial relief, he finds a Bakugan in his mother's hand; this turned out to be Skyress, a strong and rare Bakugan. She gave this to Shun because she knew that Shun was interested in Bakugan not in ninja lessons. It is unknown if she is alive. Skyress was given to Shun to look after him since she cannot look after him herself. When Oberus gave Shun his test, she used an illusionary form of a young Shun's Mother who always wanted to play with Shun, the final game she wanted to play with him, was Bakugan.

They then bring the two kids back to Gundalia, in which Kazarina hypnotizes them. In "Escape From Darkness", she and Zenet battle Fabia and Avatar Marucho. Lena was clever enough to realize that Marucho's Aranaut was a digital clone, but did not realize that Marucho was an avatar, not until Ren put his and Marucho's conversation on the arena's big screen, letting Lena and Zenet that they are battling a clone. After that, Lena and Zenet defeat the Avatar Marucho and Fabia. They then try to take Fabia back to Gundalia, but escape Bakugan Interspace when Marucho arrives. In "The Sacred Orb", Ren, Lena, Zenet, Mason, and Jesse, in their true forms, were being talked down to by the Twelve Orders. Before heading for Neathia in "Battle For the Second Shield", Lena is warned by Gill to watch her back around Kazarina, for she is loyal to no one but herself and would think nothing of sacrificing one of her subordinates to save herself. Once on Neathia, she, alongside Kazarina, battle against Shun and Drago, but lose when Dan and Hawktor arrive. After retreating back to Gundalia, Lena and Phosphos attempt to ambush Kazarina, knowing she would sell her out to save herself, but her plan fails when Lumagrowl takes down Phosphos and Kazarina finishes her off.

Preyas, clearly concerned that something is wrong with Drago, leaves with Amazon, letting Drago rest. When Dan tries to explain to him about Drago's powers, Amazon does not seem to care about holding back and what he would do if he had Drago's power. Later, he and Dan rush to find Drago when Dan senses an evil presence in New Vestroia. He gets scared easily when he sees Drago out of control. Later, he and Preyas hold off Venexus until Zenthon makes the save. He comments later on how awesome and powerful Dan and Drago are when battling together. He was later killed by Mechtavius Destroyer in Blast From the Past, but was ressurrected when the Brawlers went back in time to stop Mechtavius Destroyer from destroying the universe.

"The Player"

Voiced by: Lyon Smith

• Leonidas

Voiced by: Scott McCord

He is a one-of-a-kind dragon-like Bakugan who was born in the Doom Dimension, in the first video game (his only appearance). He is able to have any attribute, and the Leonidas and Omega Leonidas Gate Cards and the 'Alpha Blaster' and 'Omega Eraser' Ability Cards.

• Omega Leonidas

The only existing evolution of Leonidas in the Bakugan video game. It evolves to counter the immense power of Battle Ax Vladitor, staying as the player's Guardian Bakugan even after fading upon Vladitor's defeat.

  Marduk

Voiced by: Dan Petronijevic
A Darkus Brawler and the villain in the first videogame. Wishing to rule all Bakugan with his Guardian Bakugan, Vladitor, who eventually evolved into Battle Ax Vladitor, Marduk was greatly saddened when his partner faded out of existence after losing the final battle to the player.

• Vladitor

Voiced by: Ron Pardo

He was banished to the Doom Dimension when he tried to take over Vestroia. When Naga took the Silent Core he was freed and he traveled to Earth. He has sharp horns and incredible strength as well as an armored covered body. He is Marduk's Guardian Bakugan.

• Battle Axe Vladitor

The evolved form of Vladitor, after he absorbed the Silent Orb (a tiny version from the Silent Core), and is still in service to Marduk, the masked villain's Guardian Bakugan. When both Bakugan faded and left their partners alone, it was Battle Ax Vladitor's remaining strength and tiny portion of good heart that brought Leonidas back to life.

Regulars

The villains in the second videogame, Battle Trainer. They drive a space ship called the Dark Star and stole all Bakugan from Earth, and also deleted Dan's memory. This alien group is led by Vector (Professor Trecov); and his pals Rurock, Viper and Mantis. They wanted to create the most powerful Bakugan with the silent core, but after their defeat, they escaped but not before claiming vengeance on Dan. After the game's ending, it is revealed that the Regulars were working for Naga.

  Abyss

Abyss is a character in Bakugan: Defenders of the Core. She is considered the goddess-guardian of her "Earth"s core, and the one responsible to alterate the Bakugan Interspace to take the Player to her reality. Spectra is after her for the whole game to power-up Maxus Helios. The only one who can see her is the player of the game. She is the alternate "Earth's" Core. She seems to get power from landmarks and holograms. Also, she grows weaker as landmarks are destroyed and vexos crystals are made. She eventually gets killed during the battle at the Earth's core. Ironically, the player was forced to destroy her because Maxus Helios was becoming too powerful because she was basically a power source. Throughout the story, she evolves your bakugan.

  Manga

  Katie Lowery

She appeared in the manga The Evo Tournament. It is unknown what her main Attribute is. Her Guardian Bakugan is Chamelia, but it was sent to the Doom Dimension. Her new Guardian became Mecha Chamelia, a mechanical Bakugan built by her father. She develops a relationship with Marucho over the internet at which point Shun reveals he knew her before meeting the others. He had helped her practice for a match and offered to lend some of his abilities if he beat her in a battle. She lost and never spoke to him again and later stole his ability cards.

• Chamelia

A Non-attributed chameleon-like Bakugan and was one of Katie's Guardian Bakugan. It was sent to the Doom Dimension by Masquerade and Mecha Chamelia took his place in the arena, and more importantly as Katie's Guardian. Drago had said that most Chamelia's were already extinct from being to weak. They have abilities of their own and are only capable of using abilities copied from their opponent.

• Mecha Chamelia

A Mechanical Bakugan from The Evo Tournament. He was created to replace Katie's Chamelia after she lost to Masquerade (maybe is Chamelia's resurrection). It, like a regular Chamelia, has the ability to copy an opponent's Bakugan and their ability cards. It was deleting people's memories of their Bakugan, and caused many people, including Dan, Shun, and Julie, to forget that their Bakugan could talk. It also completely wiped out many Bakugan's memories, causing the Bakugan affected to be unable to speak. In actuality, Mecha Chamelia had been symphoning G powers from Bakugan in the Evo Tournament to increase his own strength (memory loss was an unintentional side effect). After being defeated by Dan and Runo, Mecha Chamelia apologizes and asks Katie if he will be deactivated. Katie decides not to, provided he does not pull the same stunt again.
