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
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 leaving mysteriously.

The Fusion Fighters eventually land in the Island Zone, and find several Gizamon surrounding Archelomon. The team scatters the Gizamon, and Shoutmon asks Archelomon if he can have the Code Crown. Archelomon tells them that when a summer harvest comes, they will be able to get the crown. As the island moves, Archelomon quickly covers up any suspicion by saying that it was his stomach and so the group goes to harvest some DigiBytes.

Meanwhile, in the distance, the "leader" of the Gizamon reports to Neptunemon, and after hearing of the humans stopping them, gets upset. Tactimon then informs him that the humans were the ones that have claimed the Forest Zone and must be eliminated. Neptunemon then calls his Mantaraymon fleet to attack the island so they can find the Code Crown and take the Fusion Fighters Code Crown also.

As the group eats the harvested DigiBytes, a Syakomon informs them the Mantaraymon fleet is coming towards the island. The fleet then sends several Divermon battalions out to search for the group, while bombarding the island at the same time. Mikey then comes up with a plan to attack them from behind, so the Fusion Fighters goes while the inhabitants take cover.

The Fusion Fighters then attack one of the Mantaraymons, knocking out the Divermons guarding it. Angie then takes control of the Mantaraymon and starts firing its cannons on the other Mantaraymons, destroying them. The Divermon group in the island is wondering what is happening when they see the Mantaraymon attacking the other ones. Just as Angie is about to shoot the cannon at the Divermons on the island, Neptunemon retaliates by sending Octomon, who destroys the Mantaraymon the Fusion Fighters are on.

Mikey fuses Shoutmon and Ballistamon to form Shoutmon X2, but due to being in the ocean, are put at a disadvantage against Octomon. ChibiKamemon watches, and after remembering what Shoutmon had said to him, decides to help them. Archelomon tries to get him to come back, but is unsuccessful and the Divermons on the island take notice of this.

As Octomon is easily defeating the Fusion Fighters, Mikey then notices ChibiKamemon and DigiFuse him and Shoutmon X2 to form Shoutmon X2 Plus M, putting them on equal footing against Octomon. Shoutmon X2 easily defeats Octomon, and the group goes back on the island to celebrate. Meanwhile, the captured Archelomon is taken to Neptunemon, who demands him to give up the location of the Code Crown.
