After trying to destroy a control spire located in a city, Kari is separated from the rest of the group. Davis and T.K. return to rescue her. Kari eventually manages to free Andromon from the dark ring's control.

Mimi and the new DigiDestined have a picnic in the Digital World. But Mimi falls into a hole and, along with Yolei, is separated from the rest of the DigiDestined. They meet Palmon, but are then attacked by the Roachmon brothers, Gekomon and Otamamon, who are under the Digimon Emperor's control.

The six DigiDestined, assisted by DigiDestined all over the world and Oikawa's gathered children, destroy MaloMyotismon. Oikawa is left dying in the dream dimension and uses the power of the dimension to help restore the Digital World to its original state. Twenty-five years later, when everyone in the Real World has a Digimon partner, both groups of DigiDestined are grown and their children now hold the responsibility of protecting the worlds.

Gomamon is injured and left for dead by the Digimon Emperor. Joe goes with the new DigiDestined to save him. But soon after they come into the digital world, Cody gets hurt, and Joe stays to help him.

MaloMyotismon tempts the DigiDestined with illusions of their dreams coming true, but Davis, whose dream was that ExVeemon could grow more powerful to defeat the villain, guides them out. The others follow his example, causing the Digimon to evolve into all their forms at once.

Oikawa and the children infected with the Dark Spores try to go to the Digital World, but, due to BlackWarGreymon's sealing of the gate, travel to a different world, where MaloMyotismon, who had hidden within Oikawa ever since his defeat, makes his appearance.

One of the children's Dark Spores grows into a Dark Flower, which is harvested by Oikawa despite the DigiDestined's best efforts to stop him. Cody's grandfather tries to convince Oikawa to give up villainy, but fails. Before Oikawa can kill him, however, BlackWarGreymon takes the fatal blast. The dying mega uses the last remnants of power to seal the digital gate at Highton View Terrace.

BlackWarGreymon confronts Oikawa, who tells him the truth about his creation. The digimon tries to destroy Oikawa, but is stopped by both WarGreymon (which was the result of another power boost Agumon received from Azulongmon) and Imperialdramon Fighter Mode. After a fierce battle, they plead with BlackWarGreymon to befriend them.

Oikawa, having no more use for Ken, attempts to hand him off to Daemon, however, Davis intervenes. The other DigiDestined arrive, and with their help, Ken is able to open a gate to the Dark Ocean and send Daemon through it.

Yukio Oikawa and his cronies kidnap Ken, and use his Dark Spore to create new ones to implant in gathered children. Meanwhile, Daemon's servants engage the DigiDestined, and, in order to win, the DigiDestined must kill both of them.

A new enemy, Daemon, appears, along with his followers. With the aid of Azulongmon's power given up by the older digimon, Imperialdramon Dragon Mode triumphs against SkullSatamon by mode changing into his Fighter Mode!

Ken and Matt help out the a Mexican DigiDestined, while Sora and Yolei helped those in Russia and Siberia. They all return back to Japan, just in time for Christmas. However, Arukenimon is still up to something.

In Australia, Cody and Joe meet with Derek to fight marine Digimon. In Paris, T.K. and Tai receive help from T.K.'s grandfather to save a French DigiDestined held in Versailles.

The Japanese DigiDestined split up. Mimi and Davis team up with the American DigiDestined, while Kari and Izzy go to help those in Asia.

Gabumon is captured after causing an uprising in a Gazimon village. He escapes and gets badly beaten up. Matt and the rest of the new DigiDestined go to the digital world to save him.

The DigiDestined receive one of Azulongmon's Digicores, which results in Paildramon mega digivolving into Imperialdramon Dragon Mode, who helps them to join the other DigiDestined worldwide. It also restores the original 8's ability to go to ultimate level.

As Christmas approaches, the DigiDestined take on a festive mood. Ken goes so far as to throw a party (the first time he was truly happy in a long time). The younger group brings the digimon partners of the original DigiDestined into the real world. However, their holiday cheer ends when control spires and rampaging digimon appear worldwide.

While the DNA digivolved digimon hold off BlackWarGreymon, Davis gets the idea of moving the last Destiny Stone with the D3s. Instead of moving it, this summons Azulongmon, the digimon that appeared as earlier destiny stones were destroyed. BlackWarGreymon attacks Azulongmon but quickly is shoved off and leaves after learning what his purpose is. After explaining many such things as the true purpose of the control spires and armor digivolving, Azulongmon warns the group about their true enemy, the one controlling Arukenimon and Mummymon. Davis sees a control spire in the real world.

The DigiDestined head out to eat at another Digitamamon restaurant. Arukenimon and Mummymon are already there, badgering the digimon to tell them what his soup recipe is. When he refuses, they look for themselves, and discover the final destiny stone in the soup springs. When BlackWarGreymon shows up, Angemon and Ankylomon DNA digivolve into Shakkoumon, and the episode ends.

Cody, worried about T.K., goes to see Matt, who tells him about how T.K. still carries the scars from the battle against Devimon. BlackWarGreymon destroys one of the final two destiny stones.
