Teaming up with three new combatants - Fabia, Jake, and Ren - the Battle Brawlers strive to foil the goals of the nefarious Gundalian Protectors, known as the Twelve Orders. Their diabolical scheme involves not only wiping out Neathia, but possibly Earth as well. By entering the Bakugan Interspace via virtual reality, the group encounters these adversaries. Time is of the essence as they fight to protect the Bakugan and emerge victorious once again.
