Once upon a time, in the illustrious Canterlot City, a mysterious phenomenon occurred. There were these mysterious cards that started falling from the sky, and what came out of these cards were small toys that, when placed on these cards, turned into powerful creatures.

It was fun, but everything changed when the Bakugan started talking to them. That is when The Game of Bakugan hit the peak of its popularity.

Now, a young Gundalian named Twilight Sigma has made a great point in her Bakugan career on earth with her partner, Darkus Cyber Dharak, as she will make new friends and foes along the way.

"But soon, Emperor Meliodus, the Grand-Father of Barodius and first ruler of Gundalia, has come out of hiding for a chance to seek vengeance on not just humans and bakugan, but also on his own people, who celebrated his grandfather's demise.

Will Twilight be able to save her world and become the strongest brawler in Gundalia? Only time will tell.
