One day, a flood of magical cards rained down from the sky and were collected by unsuspecting children. Unaware of the great power of the cards, the children created an exciting new game called Bakugan Battle Brawlers - but once they began to play it, they discovered that the monsters were real! Now Daniel and Drago must try to save Vestroia, the home dimension of the monsters in their new game. To make matters worse, they also have to contend with the mysterious player known as Masquerade, who has been taking other players' Bakugan from them.
The future of Duel Monsters has finally arrived! With it has come a new form of dueling known as "Riding Duels," which many duelists are eager to take up and learn. One such player is Yusei Fudo, an aspiring rider duelist who lives in the slum area known as Satellite; he has been wronged by the system and is on a mission to defeat his archrival: Jack Atlus, the Absolute King of the Riding Duel. With Jack having wronged him in his past, Yusei chooses to exact his revenge by taking his title; but, with a strange, unfamiliar set of rules and many foes ahead, will he ever reach Neo-Domino City and claim his prize?
At the island-based Duel Academy, young potential duelists gain the skills they need to become a top notch duelist. The students are divided into three classes named after the three Egyptian god cards: the top ranked Obelisk Blue, average Ra Yellow, and beginner Slifer Red. Jaden Yuki is currently a student at the academy, and is a huge fan of the famous Yugi Mutou. Though Jaden must start off slowly in the Slifer Red class, his goal is impressive: to become the next King of Games! Together with Syrus, Chumley, and Bastion, their dueling matches will draw them into the shadow realm, and into trouble. Jaden and the gang must do the only thing possible: get their game on!
