While leading Dorulumon and the Fusion Fighters through a cavern, BlueMeramon reveals how he is repaying his debt to Dorulumon for saving his life when Tactimon ordered a raid on the Zone they were conquering regardless of casualties. Taking the Fusion Fighters to Mikey's Fusion Loader, BlueMeramon takes an attack from SkullMeramon meant for Dorulumon. Shoutmon destroys SkullMeramon, but BlueMeramon dies and thanks Dorulumon for what he had done for him. The Fusion Fighters proceed to defeat the RedMeramon army before AncientVolcanomon absorbs them to assume his FusedAncientVolcanomon form that overwhelms the group before he turns his attention to Dorulumon. After summoning the GarurumonDigiCard to save Dorulumon, Mikey proceeds to digifuse him into Shoutmon + Drill Cannon to weaken FusedAncientVolcamon before Shoutmon X3 is formed to finish their opponent off. While that occurs, with Tactimon overpowering MailBirdramon, Christopher summons Greymon to cover their escape.
In the aftermath, Dorulumon and Cutemon agree to join up with the Fusion Fighters. The Fusion Fighters also receive the Magma Zone's Code Crown as they head to the next zone.
