Suddenly, they are all transported to the Digital World. There, they are surrounded by hostile Digimon led by MadLeomon. They are saved by Shoutmon, the red creature, who wants to become the Digimon King. Together with Shoutmon and his companions, they face off against MadLeomon and his troops, leading to a battle in which they ultimately defeat MadLeomon.

Despite their initial struggles, the Fusion Fighters, aided by Cutemon and Dorulumon, defeat MadLeomon. During the battle, Mikey recalls his dream, and they discover a Code Crown, meeting the mysterious girl Nene Amano.

Nene Amano introduces herself and explains that the Digital World is divided into Zones, each with its own Code Crown fragment. Collecting all the fragments would grant control over the Digital World. Mikey, Angie, and Jeremy, with Nene's guidance, arrive at the Island Zone. There, they save Archelomon from Gizamon searching for the Code Crown. Archelomon mentions the Code Crown is in a difficult-to-reach location and asks for Digibites for an upcoming festival.Meanwhile, the Bagra Army's commander Neptunemon learns about the Fusion Fighters' presence and sends a fleet of Mantaraymon and Divermon to stop them. To infiltrate the fleet, the Fusion Fighters go underwater. Neptunemon's forces attempt to sink the hijacked Mantaraymon and drown its occupants, but Shoutmon ×2 Plus M, formed with the help of ChibiTortomon, turns the tide. However, ChibiTortomon's bravery leads to Archelomon's capture by Neptunemon

Neptunemon discovers the location of the Code Crown from Archelomon. Mikey, Angie, and Jeremy encounter Flymon on their quest for the Code Crown and face a unique guardian, KingWhamon, who is the island itself.

Upon leaving KingWhamon, they are attacked by Neptunemon's Ebidramon. The battle proves challenging for Shoutmon ×2, leading them to seek the assistance of legendary Digimon data stored in DigiCards. Leviamon and Shoutmon ×2 work together to defeat Ebidramon. However, their victory is short-lived as Neptunemon sends an army of Seadramon to confront the Fusion Fighters in an attempt to take the Code Crown.

Neptunemon uses Archelomon as leverage to obtain the Code Crown and DigiCards from the Fusion Fighters. Christopher Aonuma arrives on MailBirdramon and offers to deal with the Seadramon to retrieve the items, but Mikey declines. Instead, Mikey summons a group of MarineAngemon using MarineAngemon's DigiCard to subdue the Seadramon and Neptunemon. With the help of Shoutmon ×2, Jeremy, and a bridge of Syakomon, Mikey reaches Neptunemon and frees Archelomon. However, Neptunemon traps them on the frozen ocean surface. Dorulumon intervenes to rescue the Fusion Fighters and Archelomon. The three Digimon, Shoutmon, Ballistamon, and Dorulumon, DigiFuse into Shoutmon ×4 to face Neptunemon's powerful weapon.

They fall into a trap set by SkullMeramon but are later aided by Dorulumon. They DigiFuse into Shoutmon ×3 to defeat SkullMeramon. The episode ends with their encounter with AncientVolcanomon, a high-ranking Bagra Army officer.

The Fusion Fighters realize that continuing their battle with AncientVolcanomon could lead to the cave's collapse and harm the prisoners. They decide to surrender and give AncientVolcanomon a fake Fusion Loader to gain access to the prisoners' cell. Mikey, Cutemon, and Dorulumon encourage the prisoners and start digging a way out. AncientVolcanomon discovers the fake Fusion Loader and sends SkullMeramon with an army of RedMeramon to recapture them. Shoutmon ×2 defeats SkullMeramon's group, but they face a tough challenge against AncientVolcanomon. Mikey instructs Shoutmon ×4 to plug the volcano on AncientVolcanomon's back, causing magma buildup and defeating him. As the sun rises, they encounter Tactimon, one of the Bagra Army's three generals. Tactimon reveals that Dorulumon was once part of the Bagra Army, serving as his right-hand man.

Mikey, Angie, and Jeremy travel to the Sand Zone, where they learn about the fractured Digital World Zones and the treasures within them. They encounter Blastmon, one of the Bagra Army generals, but he is more interested in the treasure than in fighting them. The Fusion Fighters work with Deputymon to reach the treasure and confront Pharaohmon, the ruler of the Sand Zone. However, they discover that Pharaohmon and Deputymon were testing their worth, and a battle is averted. Mikey receives the Sand Zone's Code Crown, while Blastmon faces off against Christopher and his partner Digimon.

Blastmon continues his battle with Cyberdramon and Sparrowmon, while the Fusion Fighters are under fire from Reapmon. Reapmon reluctantly allows Mikey to retrieve his Fusion Loader after seeing a revealing statue. Blastmon eventually leaves the battle, exhausted. Mikey falls into a gorge and encounters Reapmon, who reveals the statue's connection to the Warriors of Light, led by Angemon.

Laylamon, in her anger, sends the Fusion Fighters to a perilous Digital Zone.
