Through a telescope in the digiworld, the Dark Masters observe the events unfolding on Earth, preparing for the arrival of the DigiDestined. Meanwhile, the kids arrive to find the Digital World in darkness, and soon find Chuumon hiding in the tall grass nearby. He explains how he was seperated from his best friend Sukamon, and how the world was scrambled up into a single spot called Spiral Mountain, where the Dark Masters rule. Seconds later, one of the Dark Masters, MetalSeadramon, shows up. All the digimon digivolve to their champion forms but they stand no chance against the mega Digimon, and are sent spiralling into an unfamiliar surrounding when MetalSeadramon uses his River of Power.
The children soon find themselves in a location covered in complete darkness. Angemon gets attacked and reverts to his rookie form. Machinedramon, another Dark Master reveals himself and the digimon digivolve to their ultimate level. They are beaten once again and using his Giga Cannon attack, Machinedramon sends the kids and their partners to yet another another completely dark location.
While in the midst of falling into the endless darkness, they group suddenly stops moving and WereGarurumon and Garudamon start fighting one another against their will. Everyone starts moving uncontrollably and Izzy is the first to notice they are acting like string puppets. It is then revealed that they are all being controlled by Puppetmon, another Dark Master. He uses his Puppet Pummel Attack, forcing the digimon to de-digivolve and sends them to yet another location, an outdoor arena.
Piedmon, leader of the Dark Masters, turns up and defeats Agumon and Gabumon in their mega forms, WarGreymon and MetalGarurumon. He then decides to take each child out one by one, starting with Mimi but Chuumon takes the shot blow and gets deleted. All hope seems lost, until Piximon whisks the kids to safety in his invisible bubble. Before leaving, Piximon informed the DigiDestined that simply being together is not going to be enough to win this battle, and they will have to figure this one out themselves. He tells them their next step should be to climb Spiral Mountain. Piximon then sends the children to safety and does his best to distract the Dark Masters.
