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.

When BlackWarGreymon destroy the third stone, a digimon briefly appears and BlackWarGreymon becomes convinced that this is his worthy opponent. At the next site, despite Angemon digivolving to MagnaAngemon after he touches the Stone, the Destined lose the battle. Gabumon tells the children about Agumon's discussion with their foe.

Yolei, while on a school trip, encounters BlackWarGreymon and several other digimon in the real world after the mega just destroyed a second Destiny Stone. Ken brings her Poromon, who helps her to combat the digimon until they are suddenly brought back to the Digital World.

BlackWarGreymon has a discussion about life with Agumon. Arukenimon and Mummymon turn their attention to the fabled Destiny Stones, damaging one with Knightmon (another creation of Arukenimon) and somehow causing BlackWarGreymon great pain in the process.

While searching for Gatomon's tail ring, Yolei, Kari, Ken, and their Digimon stumble into the Dark Ocean. When they are attacked by Blossomon, another of Arukenimon's creations, Gatomon and Aquilamon DNA digivolve into Silphymon.

While Cody's doubts towards Ken causes Ken to leave the group, Mummymon and Arukenimon combine a hundred control spires to create BlackWarGreymon. Even after Yolei brings Ken back to the group so they could form Paildramon, BlackWarGreymon effortlessly defeats the DigiDestined, but refuses to finish the job, and instead leaves Mummymon and Arukenimon, to search for a "worthy opponent."

The group travels once again to the Digital World only to be attacked by the Digimon Emperor. As they hide from him, T.K. and Kari discover their own Digi-Eggs, which allow Gatomon and Patamon to armor digivolve into Nefertimon and Pegasusmon.

Yolei creates a counter to the strange woman's music (because she worked with Matt's band). She transforms into a Digimon called Arukenimon and a fight breaks. As the gang is about to defeat her, another digimon, Mummymon, sweeps in to save her.

The DigiDestined arrive at the giant Giga House, where the strange woman lies in wait. As they draw closer to her, the group is attacked by different kinds of insect digimon. When they find the spider woman, however, she uses her flute to take control of Stingmon and Digmon as well.
