The Rival Champions!

Xros Heart stumbles into the middle of a battle between Castle Bastia and IceDevimon's army, where they must compete with Blue Flare for alliance with the Castle.

Synopsis
Arriving in the Lake Zone, Team Xros Heart finds some frozen ToyAgumon and Pandamon. They learn from the White PawnChessmon that Knightmon is drowning in the river. Taiki dives in and unleashes ChibiKamemon to help rescue Knightmon. Afterwards, Knightmon thanks Taiki. Meanwhile, Tactimon tells Blastmon and Baalmon about his encounter with Kiriha. At the same time, some ToyAgumon and Pandamon are fighting an army of Icemon and Troopmon led by IceDevimon until Team Xros Heart arrives. They fend off the Icemon and Troopmon while the Pandamon and ToyAgumon fall back to the castle. After some attacks from Team Xros Heart, IceDevimon issues a retreat. Moments later at the castle, Team Xros Heart are introduced to the Lake Zone's princess Persiamon as Kiriha enters. Meanwhile, IceDevimon reports to Lilithmon about what happened during his encounter with Team Xros Heart. Back at the castle, everyone attends a banquet. Taiki and Kiriha have a chat while being overheard by Zenjirou, Knightmon, and Ballistamon. The conversation is interrupted when IceDevimon's army attacks the castle. Kiriha combines Greymon and MailBirdramon into MetalGreymon who annihilates most of the army. Taiki then realizes that the Icemon have found a way into the castle. IceDevimon and the Icemon with him confront Persiamon until Shoutmon arrives. When Taiki arrives with Dorulumon, Ballistamon, Knightmon, and the PawnChessmon, IceDevimon ends up absorbing the Icemon with him in order to become a much more powerful version of himself. IceDevimon ends up freezing Ballistamon. Just then, Baalmon arrives to help IceDevimon only to be attacked by MetalGreymon. When IceDevimon starts to slowly freeze Knightmon, Taiki combines Shoutmon and Dorulumon to form the Dorulu Cannon which ends up freeing Knightmon. The Knightmon and PawnChessmon combine their attacks enough to cause IceDevimon to regress back to normal and retreat. When Persiamon thanks Taiki, he collapses from overexerting himself again, as two Monitamon watch on. Meanwhile, Lilithmon is at a gate that opens to reveal a gigantic Digimon.
