Synopsis
<!-- After being discovered by in the dungeon,  talks with  to make a plan. Since fighting in the cave would cause it to collapse, killing both them and the prisoners, Mikey has Ballistamon make a false X Loader, and gives it to him as a part of surrendering. Although everyone else is shocked at this, notices that it is false since AncientVolcamon has never seen the X Loader before. believes that the false X Loader is real and is furious with Mikey giving it to him. An angry AncientVolcamon tells Mikey to be quiet, and calls for Frigimon to cool him down.

AncientVolcamon orders for several Meramon to take them to the prison place. Mikey tells Shoutmon that the X Loader was a fake, and quickly shuts his mouth to prevent the Meramons from knowing it. The Meramons take them to the prison cell, and tell them escape is impossible. Shoutmon tries to break the cell bars, but gets electrocuted by them. Shoutmon then tries to use one of his attacks on the bars, but it reflects back at him. Mikey tells the prisoners that he will try to get everyone out, but the prisoners refuse to help him because they too had tried to escape, but were caught and punished many times.

Somewhere else in the Magma Zone, a group of Troopmon scour the razed village for prisoners. A Troopmon notifies that the humans have been captured, and Tactimon tells him to begin the execution. The Troopmon then tells him that was also captured with the humans, and Tactimon then tells the Troopmon to delay the execution until he arrives. Meanwhile, in the prison cell, Mikey then tells the prisoners that they will create a new world, and inspires the prisoners to help the Fusion Fighters, since the prisoners know that anguish and despair will still come even if they stop working.

The prisoners begin to help the Fusion Fighters escape the cell by digging through the cave. Meanwhile, somewhere else at the cave, AncientVolcamon calls for DeathMeramon, and asks him if he was hurt. AncientVolcamon then tells him that he has captured the humans and that Tactimon is coming. He then asks him to examine the X Loader that he took from Mikey while Tactimon is coming. DeathMeramon looks at the X Loader, and realizes that it is a false one, since it doesn't look like anything from the actual X Loader when he was fighting Mikey. The false X Loader then collapses, and DeathMeramon tells AncientVolcamon that it is a fake. An enraged AncientVolcamon then yells "What?!!!"

In the prison cell, Dorulumon breaks through the cave walls, and Mikey thanks him for helping them out. The cave then rumbles, and the group knows that AncientVolcamon has discovered that the X Loader was a fake. As they run out of the dug tunnel, they find DeathMeramon and his soldiers waiting for them on the other side. Mikey tells the prisoners to go while the Fusion Fighters distract DeathMeramon and his soldiers. Mikey DigiFuses Shoutmon and Ballistamon to become Shoutmon X2, and has Starmon and the white Pickmons to become the Star Axe for Shoutmon X2.

Shoutmon X2 easily defeats the Meramons, and is left to face DeathMeramon. After an intense battle, Shoutmon X2 defeats DeathMeramon. AncientVolcamon then rises from the ground, furious at Mikey for fooling him. Mikey then DigiFuses Shoutmon, Ballistamon and Dorulumon to form Shoutmon X3, and then has Starmon and the silver Pickmons to form the Star Sword to make Shoutmon X4. Shoutmon X4 uses Three Victorize, while AncientVolcamon uses Big Bang Fire to counterattack. AncientVolcamon then adds another one to strength his attack and knocks Shoutmon X4 away. Mikey then decides to use the Agumon DigiMemory to distract him.

Mikey then asks Shoutmon X4 to plug up AncientVolcamon's volcano spout to get rid of his energy. Shoutmon X4 puts a boulder on him, backfiring AncientVolcamon's attack and sending him to the volcano, seemingly destroying him. As the Fusion Fighters celebrate their victory with the rising sun, Tactimon is seen on the horizon. Tactimon knocks everyone back with force. Tactimon tells the Fusion Fighters that Dorulumon was his right-hand man that conquered and destroyed many Zones, shocking everyone. -->
