What is left of Spiral Mountain begains to fall apart and the kids soon find themselves floating in darkness. Gennai tells the kids that the evil force that made the DarkMasters came from the fire wall. This evil force walked across the fire wall and threatened the end of the Digital World. There were other DigiDestined children who had defeated this evil before. Tai and the others where choosen because a new evil had come to the DigiWorld from behind the firewall. It was said that the DigiWorld would be put into darkness, this is where the kids are floating right now. Gennai gets cut off before he has a chance to tell the kids the name of the evil force. Soon the new evil appears, Apocalymon, who has all of the attacks of the DarkMasters combined. Aploycomon destroys all of the kids crests to stop the Digimon from digivolving. The kids are then sent to the "Data World" where all computer information comes from. The kids finally realize just how inprotant each of them really are to the DigiWorld, this then restores the power of their crests and they return to the "Non-Data World". This is it, now only the finally battle remains...Stay Tuned for next time…

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.

Kari has just given herself up to Myotismon. Meanwhile, the others are told that in order to defeat Myotismon they must return Kari's tag and crest to her. Gatomon is tricked into telling Myotismon who the eighth child is. Myotismon gets Kari and nearly destroys her, but the other digimon show up just in time to save her. Myotismon makes an attack at Kari and Gatomon, but Wizardmon steps up and takes the full force of the blow and is killed by the blast. Tai gives Kari's digivice to her and Gatomon digivolves into Angewomon. Angewomon strikes Myotismon with her "Celestial Arrow" and it seems that he is gone. However, the kids quickly learn that the battle is not over...The fog has still not lifted.

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.

Tai and Koromon meet with Kari in Tokyo. They discover that Digimon are appearing in the Real World and decide they must go back to the Digital World to help their friends. After Koromon digivolves into Agumon to battle an Ogremon, a portal opens back to the Digital World.

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.

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.

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.

As the building caves in on them, the kids fall into the sewers under the city. Tai and Izzy have the medicine for Kari and are searching for them. Sora, Biyomon, and Patamon find Kari, T.K. and Gatomon. Kari's fever finally breaks and she wakes up, feeling a little better than before. The group continue to search for Tai and Izzy but run into a group of WaruMonzaemon. The stange light that took over Kari before returns and helps make the Digimon stronger than ever before. The group defeats the evil Digimon and free some enslaved Numomon. While the kids follow that light, Machinedramon arrives and battles the WarMonzaemon. Still looking for Kari and the others, Tai and Izzy run into Andromon and are attacked by Machinedramon, after all of this, the two groups of kids finally meet up. Kari's "light" gives WarGreymon all the power he needs to finally defeat Machinedramon.

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.

While trying to save the digidestined from Piedmon, Piximon is destroyed. The kids suddenly find themselves back in the DigiWorld, on the edge of the beach. They soon realize that this is the same spot where they spent their first night in the DigiWorld. Shellmon suddenly attacks them, but the digimon quickly take care of the problem. MetalSeadramon sends Scorpiomon after them. Scorpiomon traps the kids in a building where he almost barbecues the kids. They are only saved when Togemon and Ikkakumon digivolve into mega. The kids then hurry to get away, but get trapped in the middle of the ocean.

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.

Matt is taking T.K. home on the train, Patamon thinks it was nice that Matt and T.K. where able to spend some time together since their parents are seperated and the two brothers don't live together. T.K. overhears Patamon saying this to the other digimon and thinks Patamon is making fun of them. After that, Patamon leaves the train and Matt and T.K. go to look for him. While looking for Patamon, they run into Pumpkinmon and Gotsumon. Myotismon shows up and when the two refuse to attack the kids, he blasts them back to the DigitalWorld. T.K. thinks it's all his fault that all of this has happened. When Patamon sences that T.K. is upset, he digivolves into Angemon and returns to Matt and T.K. The search for the eighth child now continues…

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.

Joe and Tai find Mimi being treated like a princess at a palace. Sora convinces her to sing and awaken ShogunGekomom, but ShogunGekomom attacks the kids. MetalGreymon manages to defeat him and Mimi apologizes for her behavior.

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!
