Multiple armies are fighting for dominance of the Digital World. Xros Heart, Blue Flare, Twilight, and the Bagra Army are each searching for the 108 Code Crowns that grant control of Zones, fractured pieces of the Digital World, and whoever gathers each of the Code Crowns will be able to combine them into their original form and become the "Digimon King", able to bend the entire Digital World to their will. The Bagra Army's goal is to transform the Digital World into a hellish realm of suffering, and Xros Heart, led by Mikey Kudo, must stop them.
