Island Zone in Chaos!

Using their new Code Crown, the Fusion Fighters travel to the Island Zone and learn that it is also under attack by the Bagra Army.

Synopsis
<!--COPYEDIT, GRAMMAR After introducing herself to the Fusion Fighters, Nene explains how the Code Crown is actually a fragment of a larger item created as the result of the Legendary Digimon dividing the Digital World into zones and gaining all the Code Crowns would make one ruler of the Digital World. Nene also shows Mikey how to use Zone Transfer before taking her leave while Mikey, Angie and Jeremy find themselves in the Island Zone with Shoutmon and friends, Jijimon, and Dondokomon. There, after driving a group of attacking Gizamon, the Fusion Fighters are formally introduced to the Island Zone's elder Archelomon and ChibiTortomon and learn that the Bagra Army is searching for the Island Zone Code Crown. However, the location can only be revealed once the Digibite offerings are gathered for a festival. While the Fusion Fighters help out, with Shoutmon seeing that they got an admirer in ChibiTortomon, the Bagra Army's undersea commander Neptunemon learns of their appearance and sends a fleet of Mantaraymon so his Divermon can mount a beach assault.

Luckily, the Fusion Fighters set up a plan and have Archelomon and the others hide way while they manage to commandeer a Mantaraymon and use it to sink the others while taking out the Divermon. Neptunemon retaliates by sending an Octomon to destroys the hijacked Mantaraymon and drown the Fusion Fighters underwater. When ChibiTortomon sees this, remembering Shoutmon's words of confidence, he rushes over to have Mikey Digiuse him with Shoutmon X2 to form Shoutmon X2 Plus, which allows everyone to breathe underwater and give them the skill to defeat Octomon. As Shoutmon thanks ChibiTortomon for his help, it turned out Archelomon's location ot compromised as he brought before Neptunemon to be forced into revealing the Crown Code's whereabouts.

Nene introduces herself to Team Fusion Fighters and tells them about the Code Crown, which is proof of ownership of a zone. She also informs them that the Code Crown can be used to transport to other zones, an action called Zone Transfer. Mikey then uses it to open a portal which leads his team to the Island Zone which is surrounded by an ocean. Nene disappears as mysteriously as she arrived. Once there, they save an Archelomon and ChibiTortomon from a group of Gizamon. The Bagra Army's undersea commander, Neptunemon, hears about Team Xros Heart's presence. As Team Fusion Fighters gather offerings for a festival, which is the key to finding the Crown Code, Neptunemon sends several Divermon to shore.

While Archelomon keeps the others hidden, Team Xros Heart heads underwater to infiltrate the sea vessel-carrying Mantaraymon and use them against each other. When Neptunemon gets word of this, he unleashes Octomon who destroys the hijacked Mantaraymon and drags everyone underwater. When ChibiTortomon sees this, he rushes over to have Mikey DigiXros him with Shoutmon X2 to form Shoutmon X2 Plus, which allows everyone to breathe underwater and give them the skill to defeat Octomon. As Shoutmon thanks ChibiTortomon for his help, Neptunemon's army has managed to kidnap Archelomon and learn the location of the Crown Code.-->
