Bakugan Battle Brawlers

Dan Kuso's life changed one day when random cards fell out of the sky, where he and his friend Shun invented a game called Bakugan with those cards. Together with his friends Runo, Marucho, Julie, Shun, and Alice, the group Bakugan Battle Brawlers is formed and its members are accidentally dragged into fighting for the fate of Vestroia (the Bakugan's home dimension) against Masquerade, Hal-G, and the Bakugan Naga.

It is the story of a dimension called Vestroia which loses its natural balance and merges with the human world. The creatures of this place are called Bakugan. One of the evil Bakugan called Naga was tempted and decided to take the Silent Core. Naga was also accompanied by a human called Michael in his task. So Dan and his friends decided to bring back balance by destroying Naga, as he has the Silent Core and seeks the Infinity Core.

Throughout the series more about Vestroia and the Bakugan are revealed. At the end Naga and Hal-G launch an all out assalt on the Brawlers home city to find and locate the Bakugan in posession of the infinete core: Waivern. In the end Drago blasts Waivern to make sure that the infinete core dosen't fall to Naga(Waivern already taken enough damage handed the core over to Drago). Drago then absorbes the infinete core and becomes and ultimate Bakugan with no attribute limits. He and Dan Battle Hal-G and Naga in the final fight. However Drago is injured from attack from Naga defensive Bakugan. The other brawlers soon throw in their own Bakugan to help Drago finish off the defensive Bakugan and Naga. In the end Naga is destroyed and the Silent core goes into Drago. Sadly he and all Bakugan must return to Vestroia. Drago must become the new core of Vestroia and the others because it was said that it breaks basic rules for Bakugan to be in the human world. All Bakugan return to Vestroia in the end. After a few months it is shown that Dan is going out with Runo. Dan soon sees an image of Drago in the sky saying," I'll never forget you my friend." At the end of the episode, you see that Runo and Dan are doing something together.

Dan is a boy who loves playing Bakugan and gets frustrated easily. His greatest ambition is to be the number one battle brawler in the world. He is a Pyrus battler, and his guardian Bakugan is a Pyrus-attribute Dragonoid (nicknamed Drago). His Drago loves Wavern/Wayvern, who holds the Infinity Core within her. Dan and Runo often argue with each other; Dan is in love with Runo but doesn't confess until the end of the series, when they are seen on a date together. In the anime television series, Dan is voiced by Yu Kobayashi in the Japanese language and Scott McCord in the English language. Drago is voiced by Keiji Fujiwara in the Japanese language and Jason Deline in the English language.

Runo is a tomboy who loves playing Bakugan with people that have skills to show off. Runo is a Haos battler. Her Guardian Bakugan is a Haos-attribute Tigrerra, who is very obedient to her and powerful in battle. Runo hates when people think that they can beat her just because she is a girl. She helps her parents run their family business. When Alice comes to visit, she helps Runo's family with their restaurant, which leads to Runo becoming jealous as boys came just to see her. She is Dan's best friend, and has a crush on him. At the end of the series she and Dan are seen on a movie date. In the anime television series, Runo is voiced by Eri Sendai in the Japanese language and Julie Lemieux in the English language. Tigrerra is voiced by Atsushi Ono in the Japanese language and Stevie Vallance in the English language.

He is a extremely rich boy who is very generous and intelligent, a bit like a walking encyclopedia. He loves to play Bakugan and he also likes to work on strategies. He used to be very obedient to his parents just because he wanted to please them, but that changed when he met the Brawlers. 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 are an Aquos-attribute Preyas and a Haos Angelo/Pyrus Diablo Preyas(showing up later in the series). Preyas was sent to the Doom Dimension in Marucho's battle with Klaus Von Hertzon. Later Klaus shows up with Preyas. Dan and Runo find a way to get Preyas back through defeating him in battle. Preyas evolves into a two-sided Bakugan called Preyas Angelo (Haos) and Preyas Diablo (Pyrus). Unlike the other Bakugan however, Preyas multiplies when he evolves, so Marucho got to keep the old Preyas. Preyas also has a move called "Change of Attribute" with that he can take advantage of the opponent's gate card. In the anime television series, Marucho is voiced by Ryou Hirohashi in the Japanese language and Joanne Vannicola in the English language. Preyas is voiced by Shawn Unifier.

Julie is a girl who tries to stay happy even when the worst has happened (for example, when Billy ended up under the control of Masquerade); her acting happy after something bad happened is generally just to hide up her true feelings. Julie forgets things easily, proving that she is a little scatterbrained at times. She is a Subterra battler, whose guardian Bakugan is a Subterra-attribute Gorem. At the beginning of the series, she is shown to have a little crush on Dan (which led to some arguments with a jealous Runo), but later, accepts that Dan and Runo are going out. At the end, she and Billy go on their first date. Julie has a sister named Daisy who has bested her in everything since she was a child. In the anime television series, Julie is voiced by Risa Mizuno in the Japanese language and Katie Griffin in the English language. Gorem is voiced by Hiroki Yasumoto.

Shun is a boy who is the former first ranked Bakugan brawler who later moves down to sixth position. He is a master of Bakugan, and is also Dan's childhood friend. Shun is a loner, a boy of very few words, yet is willing to help his friends at every turn almost. He is a Ventus battler. 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-attribute Skyress whom Shun received from his comatose mother in the hospital. Shun once leaves the brawlers when Dan says they don't need him. But after brawling Komba, Dan appears and asks for forgivness which Shun accepts. In the anime television series, Shun is voiced by Chihiro Suzuki in the Japanese language and Zachary Bennett in the English language. Skyress is voiced by Chiharu Suzuka.

She is a girl from Moscow. She sometimes plays Bakugan because she has the evil darkus in her control, but knows almost everything about it. Michael Gehabich is her grandfather, but after learning that her grandfather became Hal-G and works with Naga, she constantly worried about him. Alice usually just gives advice to the brawlers, instead of battling. Alice and Marucho are the 2 brawlers who mostly use strategy. However, unlike Marucho, Alice gives her strategies to the brawlers. During season 2 she left the Brawlers after finding out that she was Masquerade out of intense guilt over what she did as him, but later returns as Masquerade in time to save Dan and Drago. Once she saves them Masquerade permanently leaves her body (which Alice at first resents because she believed that she needs him), but leaves Alpha Hydranoid for her to control, although her secret Bakugan is Darkus, which she hardly uses it because of its evil. In the anime television series, Alice is voiced by Mamiko Noto in the Japanese language and Emilie Barlow in the English language.

He used to be the first-ranked Bakugan player before he left Alice's body. His goal is to send all Bakugan to the Doom Dimension with his Doom Card, so he can evolve his Hydranoid and have the ultimate Bakugan. He is a Darkus battler. He is revealed to be Alice in episode 38 and his origin is revealed in episode 39. Masquerade came to life when negative energy changed Alice (who doesn't know she is Masquerade or what happens when she becomes him). Darkus Hydranoid is Masquerade's guardian Bakugan. He battles with Dan in episode 38 and loses. He is actually Alice, but Masquerade disappears from her body (although at first, Alice doesn't want him to leave). In the anime television series, Masquerade is voiced by Souichiro Hoshi in the Japanese language and Lyon Smith in the English language.

Also known as Webmaster Joe. He lived in a hospital. The Brawlers used to think he was working for Masquerade, but he actually sent a message to the Brawlers to warn them that Masquerade was plotting against them. When he met Dan, he said he would only tell him if he was working for Masquerade if Dan beat him in a battle. In the middle of the battle he fainted. When he woke up they asked him to be one of the Brawlers. He gladly accepted. Sometime after he moved to the Brawlers neighborhood, he found Wavern/Wayvern who had the Infinity Core inside her. Wavern/Wayvern is a White One, meaning she has no attribute, but her abilities in battle are considered Haos. Wavern/ Wayvern is Joe's guardian Bakugan. It is also revealed that Wavern/Wayvern is Naga's younger twin sister. Joe is the first person to beat Masquerade at Bakugan with his new Bakugan Wavern/Wayvern. In the anime television series, Joe is voiced by Souichiro Hoshi.
