Disaster in the Dust Zone!.Mikey Kudo, Angie Hinomoto, and Jeremy Tsurgi are forced to flee from Axeknightmon and Christopher Aonuma. The Fusion Fighters manage to escape with Puppetmon's help through a shaft in a factory. Upon Laylamon’s arrival, she encounters Axeknightmon as he makes an offer for an alliance to deal with the Fusion Fighters. Laylamon accepts Axeknightmon’s offer. Laylamon intends to take the Code Crown fragments from Axeknightmon once their partnership is at an end. Later that night, the Fusion Fighters are joined by Sparrowmon who reveals to Mikey that Nene Amano is being held in Axeknightmon’s tower. Sparrowmon also reveals to the Fusion Fighters that Nene is only helping Axeknightmon to create an item called the Darkness Loader as he is holding her younger brother captive. The next day, Mikey's group attempts to rescue Nene when they are confronted by Christopher and his forces. Realizing that Christopher is not acting like himself, Mikey manages to knock Christopher out of the Blazing Orb's influence as their teams join forces to battle the armies Axeknightmon and Laylamon amassed. As Shoutmon ×4, MetalGreymon, Deckerdramon, and Cyberdramon hold their enemies off, Mikey and Sparrowmon reach Nene with Mikey promising her that they will save her brother. Once Nene is saved, Mikey forms Shoutmon ×5 to wipe out the Guardromon while using the MetalGarurumon DigiCard that Puppetmon provided to take out the Tankmon alongside MetalGreymon Cyber Launcher. Unfortunately, Axeknightmon reveals the completed Darkness Loader and uses it to force DigiFuse SkullSatamon and SkullGreymon into his weapons to destroy the Dust Zone. The Fusion Fighters and Blue Flare teams avert the attack as the Dust Zone's Code Crown appears from the wreckage of Axeknightmon’s tower. Mikey leaves the Code Crown fragment to Puppetmon, while Christopher accepts him as a worthy rival before leaving. Nene joins the Fusion Fighters. Meanwhile, as Tactimon is livid over the turn of events of their group contending with three other parties for ownership of the Digital World, Bagramon finally decides to get personally involved as he shows up physically in front of Tactimon.
