The Original Fighting Bakugan
Haos Tigrerra
Tigrerra
Debuted In: Battle Brawlers
Voiced by: Atsushi Ono (JP), Stevie Vallance (EN), Circe Luna (LA SP)
- Blood Knight: She definitely seems to like having a fight, though she is smart enough to be a strategist when needed.
- Good Scars, Evil Scars: When in her true form, she is shown to have a thin scar over her left eye, likely from a prior battle.
- Great White Feline: Tigrerra is a Haos attribute Bakugan and the Guardian of Runo Misaki. She is a large white tiger and gains a bipedal form when she evolves into Blade Tigrerra.
- Heterosexual Life-Partners / Platonic Life-Partners: Tigrerra and Preyas are some of Drago's closest friends. When he discovers Helios was the one who captured her for the Vestals, he flips his shit.
- Intrigued by Humanity: Tigrerra is always confused by some of humanity's actions and emotions, showing surprise with how fast they can go from one emotion to another very quickly.
- Light 'em Up: Haos-attributed.
- Mama Bear: She does not take it well if one of her companions falls in battle.
- Mighty Roar: She always lets one out when she is on the battlefield.
- Panthera Awesome: She is a tiger after all.
- Parental Substitute: Seems to take this role with Runo.
- Single Tear: Implied in "Just for the Shun of It", as she notes that humans are strange, while a sparkle that is clearly indicated to be a tear appears at her eye.
- She's a Man in Japan: In the English version she's female, but in the Japanese version he's a male, which becomes more obvious after he evolves to Blade Tigrerra.
- The Stoic: Like Drago and Skyress, Tigrerra is one of the most level-headed Bakugan, and rarely shows outright emotion.
- Took a Level in Badass: In New Vestroia, both her G-power and abilities were buffed. In Mechtanium Surge, she does some good damage against Mechtavius Destroyer, making the souped-up Mechtogan Titan keel over in pain.
- Worthy Opponent: She always did want to fight Drago.
- Wolverine Claws: More pronounced as Blade Tigrerra, but they were always there.
Subterra Gorem
Gorem
Debuted In: Battle Brawlers
Voiced by: Hiroki Yasumoto (JP), Stephen R. Hart (EN), Salvador Reyes (LA SP)
- The Big Guy: Size-wise, he could probably stand next to some of the tinier Mechtogan the same way a child would stand next to an adult.
- Gentle Giant: Despite his intimidating size and deep voice, he's really sweet and kind to the ones he cares about, especially Julie.
Darkus Hydranoid
Hydranoid
Debuted In: Battle BrawlersVoiced by: Izō Oikawa (JP), Craig Marshall (EN), Robert Tinkler (EN; episode 26 only), Blas García (LA SP), Raúl Estrada (LA SP; episode 45 only)
- Berserk Button: Is none too pleased with the Vexos creating a mechanical ripoff of him, enough that Hydranoid wants to and becomes the one to personally destroy it.
- Blood Knight: He may enjoy his times of peace, but at his heart Hydranoid loves himself a good fight.
- Chainsaw Good: As Dual and Alpha Hydranoid, he has a rotating chainsaw blade in his belly.
- Dark Is Evil: While serving Masquerade, Hydranoid was constantly obsessed with gaining power and didn't care how many Bakugan he had to send to the Doom Dimension to do it.
- Dark Is Not Evil: Mellowed out a lot while being Alice's partner.
- Heel–Face Turn: His Undying Loyalty for Masquerade also means he'll stay loyal to the much sweeter Alice.
- Multiple Head Case: Grows one additional head and tail with each evolution.
- Redemption Demotion: Played with; even after becoming a good guy, Hydranoid remained the brawlers' strongest asset outside of Drago for the remainder of Season 1. From Season 2 onwards, however, he got shafted by the writers and even decreased in G-power, whereas Preyas; Tigrerra, and Skyress still got great showings.
- Readings Blew Up the Scale: In his debut, his at the time insane G-power of 450 caused Dan to believe their measuring equipment was faulty. It wasn't.
- The Rival: For Drago, in Season 1.
- World's Strongest Man: Was the first Bakugan to aspire to become the "Ultimate Bakugan", and had the show ended at Season 1, he would have been the top contender, seeing how Naga was dead and Drago Ascended to a Higher Plane of Existence. Also likely the reason why the Vexos chose to create a Mechanical Bakugan in his likeness.
Wavern
Wavern
Debuted In: Battle BrawlersVoiced by: Nao Takamori (JP), Katie Griffin (EN), Norma Echevarría (LA SP)
- Big Good: She serves as this for the first season being the Keeper of the Infinity Core and the Guardian Bakugan to Joe.
- Cain and Abel: The Abel to Naga's Cain.
- Damsel in Distress: While the Infinity Core does make her more than capable of defending herself, holding onto it for so long is draining her strength and slowly killing her. Not to mention that the sheer power that comes with the Infinity Core causes her to become a target, especially for Naga.
- Healing Hands: She fully heals Joe of his medical problems when they first meet.
- Light Is Good: She is in possession of the positive energy of the Infinity Core, which she can use to heal those near death and repel negative energy, and is the one being standing between Naga and ultimate power.
- The Lost Lenore: Her death at the end of the first season still haunts Drago to this day, and is the reason why Drago is determined to protect his fellow Bakugan allies.
- Not So Above It All: She is mostly a relatively serious person who rarely makes comedy a priority, yet when she reunites with Drago, she shamelessly flirts with him in front of the Brawlers, much to his annoyance.
- Official Couple: With Drago. She outright confirms it when Julie asks if they were together.
- Our Wyverns Are Different: Besides her name being directly derived from the word "wyvern", she's also a bipedal dragon with bat-like arm-wings.
- Physical God: She was originally powerless, but when she became the inheritor of the Infinity Core, Wavern becomes this.
- Single Tear: Sheds this when Naga threatens Joe.
- Spirit Advisor:
- Her first appearance has her do this to Joe, when she appears in the sky to inform him about the Infinity Core.
- She later becomes one for Drago after her death.
- Twin Telepathy: Possessing the Infinity Core allows her twin brother Naga to communicate with her using the Silent Core.
- The Mentor: To Joe, and later after her death, to Drago.

Pyrus Fourtress
Debuted In: Battle Brawlers
Voiced by: Susumu Akagi (JP), Ron Pardo (EN), Jorge Ornelas (LA SP; episode 22)
- Split Personality: Has a different personality for each of his faces.
Haos Tentaclear
Debuted In: Battle Brawlers
- Blinded by the Light: His signature attack is to shine too brightly for the opponents' eyes.
- Faceless Eye: It's a giant, floating eye.
- The Speechless: Due to being a massive floating eyeball, there's a pretty good explanation as to why Tentaclear is the only Guardian Bakugan to never speak.
Ventus Harpus
Debuted In: Battle Brawlers
Voiced by: Ayumi Tsunematsu (JP), Julie Lemieux (EN), Karla Falcón (LA SP)
Subterra Cycloid
Debuted In: Battle Brawlers

Season 2 Allies
Other Bakugan
Subterra Wilda
Debuted In: New Vestroia
Voiced by: Kenichiro Matsuda (JP), Ron Pardo (EN), Gavin Hammon (EN, Defenders of the Core), Francisco Villasis (LA SP)
- Chuck Cunningham Syndrome: Despite Mira's return in the second arc of Mechtanium Surge, he is inexplicably absent, with Subterra Roxtor now suddenly filling his role as Mira's partner.
Darkus Percival
Debuted In: New Vestroia
Voiced by: Fumi Mikawa (JP), Scott McCord (EN), Mark Barbolak (EN, Defenders of the Core), Jorge Ornelas (LA SP)
- Dark Is Not Evil: He's a Darkus Bakugan, but is firmly on the side of the Battle Brawlers Resistance from start to finish.
Haos Nemus
Debuted In: New Vestroia.
Voiced by: Tsuguo Mogami (JP), Ron Pardo (EN), Corey Ringdahl (EN, Defenders of the Core), Ricardo Hill (LA SP, until Episode 9), Alfredo Gabriel Basurto (LA SP, Episode 11 onwards)
- Closer to Earth: When Baron suggests finding employment to support himself, Nemus points out that he does nothing but play video games and eat cheeseburgers.
- The Worf Effect: Gets hit with this arguably the hardest out of the Resistance Bakugan in the season's second half despite his large bag of tricks and evolution. He's the first to get his attribute energy stolen from him in a fight against Dryoid to show off how much stronger the Mechanical Bakugan have become and is barely able to keep up with Aranaut's data clone even with the assistance of a Trap Bakugan to demonstrate the strength of both Battle Gear and the Bakugan from Neathia and Gundalia.
Pyrus/Darkus Helios
Debuted In: New Vestroia
Voiced by: Takashi Matsuyama (JP), Robert Tinkler (EN, New Vestroia), Roger L. Jackson (EN, Defenders of the Core), Andrew Jackson (EN, Mechtanium Surge), Esteban Desco (LA SP)
- Cyborg: Gets himself turned into one in order to obtain more power. His evolution into Cyborg Helios MK 2 has him become even more mechanical with an even bigger arsenal of tricks.
- Chest Blaster: Gains one upon evolving into Cyborg Helios MK 2.
- Cybernetics Eat Your Soul: Inverted, as his Heel–Face Turn occurs after his operation.
- Dark Is Not Evil: In Mechtanium Surge, he was evolved into a Darkus Bakugan, but this time, he's Drago's ally.
- Evil Counterpart: To Drago, as both are canonically Dragonoids. The difference is that Drago evolves naturally using MacGuffins, while Helios evolves artificially using cybernetics and forbidden Ability cards.
- Heel–Face Turn: Along with Spectra.
- More Dakka: Oh hell, yes. Every evolution he undergoes seems to add more and more weapons onto him, and that's not even factoring in the numerous Battle Gears and BakuNanos he has.
- Race Lift: Becomes a Darkus upon his evolution into Infinity Helios.
- Reversible Roboticizing: His evolution into Infinity Helios has him apparently having shed most of his implants minus his Chest Blaster, FARBAS system, and a jet-like apparatus in place of his wings.
- Rocket Punch: Gains one of these in place of his left arm upon evolving into Cyborg Helios MK 2.
- Worthy Opponent: Acknowledging Drago as one cements his Heel–Face Turn.
Subterra Vulcan
Debuted In: New Vestroia
Voiced by: Eiichiro Tokumoto (JP), Ron Pardo (EN), Roger L. Jackson (EN, Defenders of the Core), Gustavo Melgarejo (LA SP)
- Undying Loyalty: Summed up in this quote.“Just as your loyalty to Master Spectra knows no bounds, neither does my loyalty to you, Gus.”
Season 3 Allies
Other Bakugan
Haos Aranaut
Debuted In: New Vestroia
Voiced by: Yasunori Masutani (JP), Dan Petronijevic (EN), Eduardo Fonseca (LA SP)
- Amnesiac Hero: Subverted. He faked it.
- Arch-Enemy: With Lumagrowl and Kazarina.
- Curb-Stomp Battle: His data clone from Bakugan Interspace almost effortlessly defeats Nemus even after the latter had just recently evolved, demonstrating how powerful Battle Gear and the Bakugan from Neathia and Gundalia are.
- Noble Demon: Ultimately subverted as he and Fabia are quickly revealed to be Good All Along, he is shown to be honourable even during his brief time as a Hero Antagonist.
- Tragic Keepsake: Fabia uses him to avenge Jin's death.
Darkus Linehalt
Debuted In: Gundalian Invaders
Voiced by: Eiji Takemoto (JP), Jeremy Harris (EN), Andrés García (LA SP)

Pyrus Neo Ziperator
Debuted In: Gundalian Invaders

Debuted In: Mechtanium SurgeHaos Reptak
Voiced by: George Tchortov (EN), Víctor Ugarte (LA SP)
Debuted In: Mechtanium Surge- Guest-Star Party Member: He becomes Dan's secondary partner Bakugan for most of the second arc of Mechtanium Surge due to the disappearance of his real partner, Gunz. Sure enough, Reptak returns to Gunz once he returns towards the end of the arc.

Subterra Roxtor

- Guest-Star Party Member: He isn't a full-time member of the team, Marucho borrows him from Mira to serve as his secondary partner Bakugan during the second arc of Mechtanium surge.
- Intelligible Unintelligible: Speaks only in chitters that while unintelligible to the audience is perfectly understood by the other characters.
Darkus Skytruss
Debuted In: Mechtanium Surge
- Guest-Star Party Member: Unlike Reptak, whose real partner is missing for most of the arc, and Roxtor, who is just being borrowed, He and Orbeum are wild Bakugan from New Vestroia who just come and go as they please and team up with Shun because his current partner, Jaakor, is their mentor.
- Those Two Guys: He is this with Orbeum as they both serve as Shun's secondary partner Bakugan during the second arc of Mechtanium Surge and the two are never seen apart.
Darkus Orbeum
Debuted In: Mechtanium Surge
