Bakugan Battle Brawlers

The Bakugan, Drago, who will soon become Dan's closest ally, begins to explain the origin of Bakugan and the Dimension of Vestroia. His quest is to find Naga who holds the key to power in the two parallel universes, Earth and Vestroia. Drago must eliminate Naga if he hopes to restore order. But Naga has absorbed incredible amounts of energy and may be too powerful to defeat!

It seems a very gifted and mysterious Bakugan player named Masquerade has been stealing Bakugans from kids all around the world. When Dan hears about this through his friends on the web, he decides to put an end to it and challenges Masquerade to a battle. But Masquerade has a secret weapon called a Doom Card, which sends the opponent Bakugan to its final demise.

Masquerade teams with a young Bakugan player named Rikimaru by offering him a very special Bakugan.

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

Dan and Runo meet for the first time other than on the Bakugan web-site and are surprised that they actually live in the same town! Dan accidentally drops his wrist computer, and after he is gone, Runo notices it and picks it up. She sees that Dan has been challenged to a battle by Masquerade down by the river. She decides to go in his place, but ends up dueling against a boy named Tatsuya.

While at an amusement park, Dan and Runo are invited on stage to assist two brothers performing a magic act. Dan is offered to pick a card and things go from bad to worse when his choice is revealed to be a Doom Card! It just so happens that the brothers are working with the mysterious Masquerade and they trick Dan and Runo into a battle.

Marucho reveals that he has secretly moved into Dan's neighbourhood and throws an elaborate welcoming bash. Else where, the famous pop band duo, 'Jenny and Jewls' are approached by Masquerade who makes them a business offer they can't refuse. The pair crash Marucho's welcoming party and face off against the Bakugan Brawlers.

Dan and Marucho are pitted against the two pop star princesses, Jenny and Jewls, who have been recruited by Masquerade.

Masquerade convinces two boys into using the Doom card against the Bakugan Battle Brawlers. The boys find Runo and Marucho who are at the airport to pick up their website pal Alice. Luckily Alice is skilled in the finer points of combination battle, and coaches her friends to victory. But Alice is fighting her own battle; she has a dark secret that will affect the future of her friends!

Julie and her childhood friend Billy go toe-to-toe in a Bakugan Battle. Although Julie is defeated by Billy, she is impressed with his skill level and his Bakugan "Cycloid". They make a great team and Julie desperately wishes that she could also befriend a talking Bakugan. Later, when Julie really admits to herself how lonely she is, the Bakugan Gorem appears to her.

Marucho and Runo realize that the combined strength of the Battle Brawlers doesn't match up to Masquerade's power. Without Dan's knowledge, they visit Shun to try and convince him to join the team. Shun's Grandpa tries to send them away but Shun challenges them to a Brawl. If Marucho and Runo beat him, then he'll join. If not, he walks away...

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 recalls the last battle that he had with Shun and we discover why Shun decided to leave the game for good. Shuns' mother gives him a very special Bakugan "Skyress", to watch over him.

Masquerade has been destroying kids' Bakugan all over the world and the Brawlers need to put a stop to it.
