Bakugan

Drago, a Bakugan destined to become Dan's closest ally, explains the origin of the Bakugan and the Dimension of Vestroia.

A very gifted and mysterious Bakugan player named Masquerade has been stealing Bakugans from kids all around the world, spurring Dan to investigate.

Masquerade teams with a young Bakugan player named Rikimaru by offering him a very special Bakugan. Meanwhile, Dan and Drago have a falling out.

Dan is having a hard time without Drago around. Feeling frustrated, he takes his anger out on a school friend name Ryo.

While at an amusement park, Dan and Runo are invited on stage to assist two brothers performing a magic act, giving them a chance to learn about paired battles.

Marucho reveals that he has secretly moved into Dan's neighbourhood and throws an elaborate party. Meanwhile, Masquerade is scheming behind the scenes.

Dan and Marucho are pitted against a pair of two popstar princesses, "Jenny and Jewls." They're unaware the duo has been recruited by Masquerade.

Masquerade lures two boys into using the Doom card against the Bakugan Battle Brawlers. These misguided brothers challenge our heroes in the hopes of reuniting their friend with her long-lost brother.

Julie wants a talking Bakugan of her own -- and gets one! She and her childhood friend Billy go toe-to-toe in a Bakugan Battle.

Marucho and Runo realize that the combined strength of the Battle Brawlers isn't a match for Masquerade's power. The team tries to recruit the best Bakugan player in the world to join them.

Alice realizes that she may have a connection to the mysterious Hal-G but can't get up the courage to tell the rest of the Brawlers. Meanwhile, Dan battles his old friend Shun.

Masquerade has been destroying kids' Bakugans all over the world and the Brawlers need to put a stop to it. Dan and Shun team up to do just that.

Five of the top ten Bakugan players gather at a mysterious mansion. Alice, one of the Battle Brawlers, reveals that her grandfather is the scientist who discovered the world of Vestroia.

The Brawlers head off to Bakugan Valley looking for the Infinity Core. They meet up with Julie and encounter a brainwashed battler.

The Bakugan Battle Brawlers continue their search for the Infinity Core and Shun becomes convinced that someone is spying on them. The team fights Chan, who's hypnotized by Naga and Masquerade.

While searching for information on the Infinity Core, the Brawlers discover a lead that takes them to a huge castle in Germany -- where tragedy awaits.

Marucho and Runo jump through a portal to go after Klaus. They discover Masquerade's computer, and an official ranking of all Bakugan players from around the world.

Julie finds herself in a brawl with her childhood friend Billy. She has to win in order to save him from Masquerade.

Dan and Shun have a falling out and Shun takes off on his own to seek out and destroy Masquerade. Shun eventually realizes the importance of friendship and rejoins the group.

Masquerade and the remaining few players who are still hypnotized by Naga try a new tactic, bringing Preyas back from the Doom Dimension.

Dan, Marucho, and Runo enter into battle with Klaus, Chan, and Julio, in an attempt to discover where Masquerade is hiding.

The Brawlers have reason to suspect Joe the webmaster has been spying on them, so they head out to investigate.

Alice befriends a young Bakugan competitor named Christopher and teaches him how to be a top player.

Runo suspects Alice is secretly spying on the Brawlers and giving information to Masquerade. The gang eventually learns the importance of trust.
