This timeline is for the original Japanese version of the show. Japanese names are used for the sake of difference, and as I don't know the episode names, they are not included.


The ABC (Atanasoff-Berry Computer) - the very first computer - is built, and lays down the foundations of the DigiWorld (from Brave Tamer video game, see next entry).

The first patented digital computer, ENIAC (Electronic Numerical Integrator And Computer), is created. With it's activation, the foundations laid by the ABC are built upon, and the DigiWorld is created. From the ABC and ENIAC, various multiple DigiWorld realities grow, which run parallel with the various multiple Earth realities in existence in the multiverse.

This information comes from the "Brave Tamer" video game. While continuity glitches between the games and anime mean that the video games may or may not be in continuity, this game explains that all the myriad "alternate universes" in Digimon - "Digimon Adventure," "Digimon Tamers," "Digimon Frontier," etc - all grew out of ENIAC and the ABC. Hence, the ENIAC explanation can be taken as canon for this and all timelines.

One iteration of the DigiWorld also runs closely parallel to two other unrelated dimensions - one, a kalidoscopic world that possesses the power to transform thoughts and dreams into reality, and the other, a grim, foreboding ocean that has the ability to make the dark thoughts of others come to life. While the dream dimension appears uninhabited, the World of Darkness is known to be occupied, at the very least, by Dagomon and his sevants. The DigiWorld is tied closely to both these worlds, and absorbs a fraction of the dream dimension's power to make thoughts reality. Meanwhile, as the years pass, databytes from Earth's Internet continue to add to the Digital World, while at the same time, the DigiWorld's portion of the dream dimension's power starts to give form to the thoughts, dreams, myths and spiritual beliefs of Earth's populace - combined with digital data, this merging produces Digimon, the inhabitants of the DigiWorld.

Yukio Oikawa and Hiroki Hida make contact with the DigiWorld as young boys via Hiroki's video game system. Hiroki's father, Chikara, puts a stop to what he considers childish games. Hiroki and Oikawa are heartbroken, but stay together, sharing their dreams of visiting the DigiWorld some day.

An evil being comes from beyond the Wall of Fire, and the original five Chosen Children are called upon to battle and defeat it.

Another being comes from beyond the Wall of Fire (later to be known as Apocalymon). It has been said that the time-travelling Millenniumon was resposible for breaking the seal that allowed this being to enter the DigiWorld. It's presence, like the first being, causes the DigiWorld to warp, throwing its time out of synch with that of Earth, and creating evil Digimon, among them, the Dark Masters. This time warp effect, coupled with that caused by the first being, makes the DigiWorld a lot older than it would be under normal circumstances, hence the reason that older processes such as Armour evolving can be called "ancient."

Out Of Continuity

A Digi-Egg emerges through the computer of a young boy named Wallace, and hatches into twin Digimon. As time passes, the Digimon evolve into their Baby 2 stages.

At Hikarigaoka, in Tokyo, Japan, a Digi-Egg emerges through the computer of Taichi and Hikari Yagami. The egg hatches into a Botamon, which evolves into a Koromon, an Agumon, and then a Greymon, to battle Parrotmon, who emerges from a gateway to the DigiWorld that exists at Hikarigaoka. During the course of the battle, it seems the two Digimon destroy each other, but in reality, they are drawn back into the DigiWorld, and Taichi, Hikari and six other children watching the fight are chosen by the Powers That Be of the DigiWorld to be the next Chosen Children.

Out of Continuity
As the battle between Greymon and Parrotmon happens in Japan, in Colorado, Chocomon, one of Wallace's Digimon, is taken away by a dark energy, pulled into another dimension, where he is infected with a virus and driven insane.

Between 1995 and July 1999
In Japan, the eight children move out of Hikarigaoka, the memories of what they saw suppressed, the damage done by the battle blamed on a terrorist bombing.

Hiroki Hida dies, taking a bullet for an important political figure. He leaves behind a wife and son (Iori), and a shattered Oikawa.

In the DigiWorld, the mystery group that watches over it fashion the Digivices, Tags, Crests, and the Digi-Eggs that will hatch into Digimon that will belong the eight new Chosen Children. A brutal attack by the Dark Masters leaves the whole group dead, save for Gennai. Piemon steals the Crests and Tags, while Gennai escapes with the Digi-Eggs and Digivices. He loses one set as he flees, and hides the rest on File Island.

The Crests come to be scattered across Server. Devimon emerges and plots his takeover of File Island, coming into possession of the Tags, which he hides away.

The eight Digi-Eggs hatch, and, over time, the Baby 1 Digimon evolve into Baby 2s - even Nyaromon, the Digimon who hatched from the lost egg. As more time passes, the seven Digimon wait on File Island for the coming of their partners, but Nyaromon eventually becomes Plotmon, and wanders the DigiWorld, looking for the person she was waiting for. She is found by Vamdemon, who takes her under his wing, and trains her under a brutal regimen. With this conditioning, she naturally evolves into her Adult form of Tailmon. Her memories lost, she is sent out into the DigiWorld by Vamdemon, to recruit an army of Digimon. Along the way, she meets and befriends Wizarmon.

After losing a battle with the Dark Masters, Azulongmon and the other Harmonious Ones are sealed away by the villains.

August 1st, 1999
Seven of the eight children - Taichi, Sora, Yamato, Jou, Koushiro, Mimi and Takeru - are at summer camp, when the Digivices are transported from the DigiWorld to Earth. Upon touching the Digivices, the kids are swept up in a vortex, which transports them to the DigiWorld, where they meet their Digimon, who evolve to Child and Adult to protect them from the dangers they face. After defeating Devimon, they are contacted by the now-aged Gennai, who tells them of their Crests and Tags, and of Server. They find their Tags, and head for Server, where they run afoul of Etemon. During their battles with Etemon, all the kids find their Crests. When MetalGreymon destroys Etemon, it creates a warp, which drags Taichi and Koromon back to Earth, where it is only minutes after he left.

Taichi goes home, and meets Hikari, who recognises Koromon, but does not know why (because she had seen a Koromon four years before).

Taichi is in the real world for only an hour or two, but in the DigiWorld, many months pass. All of the Chosen Children go their separate ways: Jou and Yamato are forced to work in Digitamamon's diner, Mimi stays at the Gekomon palace, and Takeru is left alone, all due to the machinations of PicoDevimon, a servant of the vampire Digimon, Vamdemon.
While searching for Gennai, Koushiro is trapped in the pocket dimension of Vadermon, where he loses his curiosity. A connection somehow opens between Koushiro's laptop and Tachi's computer in the real world, but the zombified Koushiro tells Taichi not to bother coming back..

Taichi and Agumon return to the DigiWorld, and rounds up Yamato, Jou and Takeru, foiling PicoDevimon's tricks along the way, with some unseen help from Sora. They split up to look for Koushiro and Mimi - as Yamato and Takeru search, Koushiro manages to free himself from Vademon's dimension with help from AtlurKabuterimon, and then meets up with the brothers. Jou and Taichi eventually manage to get Mimi to leave the palace, and the team then finally locate Sora, who has not been able to make her Crest glow. When Vamdemon attacks, Sora realises her love for Piyomon, who evolves to Garudamon and fends Vamdemon off.

Tailmon returns with an army, and Vamdemon, now in possession of the Crest of Light - the Crest of the Eighth Child - opens a portal to Earth (It is not clear how he obtained the Crest - he may have found it when it and the other Crests were scattered about Server, or it's possible Piemon may have given it to him, for some reason). Gennai appears in the flesh to give the kids advice on how to use the Key Cards to open the portal, which they successfully do, returning to Earth. They find that summer camp has been called off, and they are brought back to Tokyo. They go to Hikarigaoka, where they remember the events of four years previously, and then head for home. In the evening, Koushiro picks up the signal of the Eighth Child's Digivice, but his attempts to locate it are foiled by PicoDevimon and Raremon.

August 2nd, 1999
The kids ration that the Eighth Child Vamdemon is looking for must have seen the battle four years ago, and so begin searching for kids they knew who lived in Hikarigaoka then. Tailmon takes an unhealthy interest in Hikari, thinking she could be the Eighth Child, while during their search, Mimi and Sora are attacked by DeathMeramon.
In the evening, Yamato, Takeru and Gabumon meet Pumpmon and Gotsumon, two of Vamdemon's lackies. They prefer to goof off than search for the Eighth Child, and Vamdemon destroys them for it. WereGarurumon and Angemon then repel him.
Wizarmon helps Tailmon realise that Hikari is the Eighth Child, and that she is her Digimon partner. Vamdemon learns the latter fact, and captures Tailmon, planning to use her to flush out the Eighth Child.
At dusk, Vamdemon summons a mystical, electronic-disrupting fog bank, which shrouds Odaiba.

August 3rd, 1999
Vamdemon's invasion squads flood the streets, capturing much of Odaiba's population, and holding them in the city's convention centre.
One of the captives is Daisuke, a boy who will become a Chosen Child as a result of this experience.
Also among the prisoners are Mimi and Sora, who try to engineer a breakout, but Vamdemon foils their attempts. Thanks to Sora's mother's efforts, Sora, Birdramon and Lillymon manage to escape, and meet up with Taichi. Koushiro protects his family with a Digital Barrier, and heads to the TV station, where he meets Yamato's father, and explains the situation to him. Hikari gives herself up to Vamdemon to stop the chaos, and in a final battle royale, Hikari gets her Digivice and Crest thanks to Wizarmon's sacrifice, and Tailmon evolves to Angewomon, using the power of the other Digimon to energise her Celestial Arrow attack to destroy Vamdemon.

However, the entranced captives at the convention centre do not wake up - and in accordance with an ancient prophecy unearthed by Gennai, Vamdemon rises again, as VenomVamdemon, having used his bats to convert the bodies of his fallen followers into energy to resuscitate him. VenomVamdemon goes on a rampage, until the kids crack the final riddle of the prophecy, and Agumon and Gabumon become WarGreymon and MetalGarurumon. With aid from the powers of the kids' Crests, they destroy VenomVamdemon.

A warp then appears in the sky, showing the DigiWorld, which has been corrupted and reformatted. The Chosen Children save a plane from crashing - and on board this plane are Iori Hida, and his mother and grandfather. Iori sees the Digimon, marking the moment where he became predestined to be a Chosen Child.

While all this has been happening, Digimon have appeared all over Earth, and are seen by many children, who will also become Chosen Children - notably, Michael sees Gorimon in New York.

During these three days on Earth, many years passed in the DigiWorld, during which time, the Dark Masters rose again, and took control of the DigiWorld, reconstructing it as Spiral Mountain.

The Chosen Children realise they must return to the DigiWorld to stop whatever evil is happening there. Their parents watch them go - as does Yukio Oikawa, stunned by the sight of the DigiWorld, and wishing more than ever that he could go there. Vamdemon's digital "ghost" makes him a bargain, and then possesses Oikawa.

The Chosen Children return to the DigiWorld, and engage the Dark Masters in a series of battles. Many of their Digimon friends are lost, and dissention in the ranks results in Yamato, Mimi and Jou going their separate ways. During the battle with Piemon, Taichi dispatches Sora and Takeru to track them down - Sora nearly falls afoul of the living darkness that almost consumed Yamato, but it saved by Yamato and Jou. They regroup, and engage Piemon in conflict, but he uses his powers to change many of their numbers into key chains. HolyAngemon temporarily bests Piemon, and restores everyone to normal, and then Piemon and his Evilmon are defeated in a stunning final battle.

The being of darkness who emerged from the beyond the Wall of Fire takes on a physical form, and spreads his darkness to cover the entire DigiWorld. He - Apocalymon - confronts the kids and their Digimon, and destroys their Crests. He then deletes them, sending them to the Data World, where they realise the power of their Crests is inside of them. They reconstitute their bodies, and go on to destroy Apocalymon. The DigiWorld begins to reformat, and they must leave their Digimon behind.

November 1999
Taichi hears the sound of Hikari's whistle, which was left in the DigiWorld with Tailmon. He realises that a gate to the DigiWorld has opened again, and he is able to briefly communicate with Agumon via his father's computer. The gate closes again before Kari, who is out shopping with their mother, returns home to see it. (from a Japanese audio drama CD released three years after season one ended)

March 2000
A Digi-Egg appears on the Internet, and hatches into a bizarre Digimon-like creature, which eats data - apparently, it is a personification of the Y2K bug.
Koushiro, Taichi and their Digimon attempt to stop it, but it evolves to its Perfect form of Infermon. Yamato and MetalGarurumon join the fight, but it evolves to its Ultimate, Diablomon, and defeats them. Diablomon makes over a million copies of himself, and launches nuclear missiles at Odaiba, planning to wipe out the Chosen Children. It takes the fusion of WarGreymon and MetalGarurumon into Omegamon to defeat the villain and stop the missiles.

One of the kids who sees this battle on the Internet is Ryo. Another girl who sees the battle is Miyako, who will later become a Chosen Child too.

May 2000
Gennai calls the eight kids back into the DigiWorld, and instructs them to release the Crest power from within themselves. The Crest power forms a shield around the DigiWorld, restoring peace and beauty to it, and protecting it from evil - however, the eight Digimon lose their ability to evolve to Perfect.

August 2000
A Digivice emerges from the computer of Osamu Ichijouji, in front of Osamu, and his brother Ken. Osamu puts it in his drawer, vowing to find out what it is, but Ken, with childish curiosity, touches it, and is sucked into the DigiWorld. There, he meets his Digimon partner, Wormmon, and encounters Ryo. Together, they battle and defeat Milleniumon - the events of the battle go unseen (but are adapted from the video game, "Tag Tamers," which was used to create back story for Ken in the anime). With Milleniumon's defeat, the Dark Seeds appear, and fly through the air towards Ryo. Ken pushes him out of the way, and one sinks inside his neck. He becomes ill, and Wormmon cares for him for three weeks, until he is well enough to return to Earth. He returns, and it's still the same day (this is likely a Japanese writing error, as time in the DigiWorld and on Earth should be synchronised by this point - however, it *could* be passed off on Milleniumon's ability to warp space and time).

April 2001
In America, Michael, and several other American kids, receive their Digivices. Michael travels to the DigiWorld, and spends some time there, meeting his partner, Betamon.

Between August 2000 and April 2002
Osamu Ichijouji dies when he is run over by a car. Ken is consumed by grief, and is observed at Osamu's funeral by Oikawa, who is unaware that Vamdemon is within him, manipulating him.
Oikawa sends Ken an e-mail, telling him about the DigiWorld, which Ken has forgotten about. He urges Ken to use the Digivice to travel to the DigiWorld - but the Dark Seed within him instead opens the doorway to the World of Darkness. Ken dips his Digivice into the Dark Ocean, and it transforms into the Dark D-3. The Dark Seed within him activates, and, over time, his physical and mental capabilities are greatly enhanced. He gains a genius level intellect, and becomes a soccer and judo star, fast becoming a media darling. He quickly grows apathetic towards society, and his fawning parents, viewing them all as insects, beneath his notice. He returns to the DigiWorld, and begins to conquer it, assuming the guise of the Digimon Kaizer.
Ken is unknowingly moulded into the Kaizer identity by Archnemon and Mummymon, two Digimon/human hybrid beings created by Oikawa, when he transformed his DNA into data.
The designs for the Dark Rings, Dark Spirals and Dark Towers are implanted into Ken's mind via the Seed - but the Towers are the key, as they will disrupt the reality barriers, allowing Oikawa - and Vamdemon - to bypass the shield set up by the kids' Crest powers, and enter the DigiWorld.

Gennai de-ages himself (apparently by separating himself into multiple younger versions of himself), then he and his clones set about deleting information on the DigiWorld from government computers on Earth.

Qinglongmon and the other Harmonious Ones work from within their prisons to create the Digimentals, and to select Digimon to be the partners of the new Chosen Children that will soon be called on to battle the Kaizer. They rebuild the lost Crest of Kindness into the Digimental of Miracles, which is soon discovered by the Kaizer, and used in conjunction with a reactor-gateway to the World of Darkness to power his fortress base.

Mimi and her family move to New York at some point prior to September 2001, as Mimi was in living in the city at the time of the 9/11 tragedy. Mimi meets and befriends Michael.

Prior to the start of the new school year, Takeru and his mother move into a new apartment in Odaiba.

From April 2002 to June 2002
The new school year begins, and on his way to school, Takeru meets Miyako and Iori, two children who are fated to become Chosen Children. At school, he also meets Daisuke, who has a crush on Hikari, and fears that Takeru is trying to steal her from him.
The Digimon Kaizer kicks his takeover into high gear. In a scuffle with a Unimon, Tailmon loses her Holy Ring, which, unbeknownst to her, is spirited away by Gennai, so that without it, she will have the power to Armour Evolve and Jogress Evolve in the future. Agumon calls on Taichi for help. Taichi arrives, and discovers that Agumon can't evolve, due to the power of the Digimon Kaizer's Dark D-3, which is generating anti-evolutionary energies that are being broadcast by his Dark Towers. Tailmon, Patamon, Agumon and Taichi find the Digimental of Courage - when Taichi touches it, it releases three new Digivices (which Koushiro later dubs D-3s), which are received by Daisuke, Miyako and Iori. Daisuke, Takeru and Hikari travel into the DigiWorld, and Daisuke meets his Digimon, V-mon.
The following day, Miyako and Iori travel to the DigiWorld, and meet their Digimon, Hawkmon and Armadimon.
Takeru and Hikari find Digimentals of their own, which enable Patamon and Tailmon to Armour Evolve.
Many battles with the Kaizer ensue, pulling the old Chosen Children back into the fight.
At one point, the Kaizer takes control of Agumon, and turns him into a viral version of MetalGreymon.
On one occasion, Hikari is pulled into the World of Darkness by servants of the evil Dagomon. She escapes with help from Takeru, but the World of Darkness and its inhabitants are not yet through with the Chosen Children.

July 2002
The summer rolls around, and the kids have to sneak back into school to use the computer room there, continuing their battles with the Kaizer. They meet Michael, and remember the events which led to them being picked as Chosen Children.

August 1st, 2002
The kids find themselves unable to use the school computer lab to access the DigiWorld any more. The Chosen Children get together to celebrate their first trip into the DigiWorld.

August 2nd, 2002
Sora and Mimi show Miyako Tokyo Tower, where DeathMeramon attacked them, while Koushiro successfully manages to open a Digi-Port program on the Yagamis' computer.

August 3rd, 2002
At the television station, Wizarmon's ghost appears, and gives the team a cryptic warning about the future.

August 3rd, 2002 onward
The kids locate the Digimon Kaizer's base, and Taichi, Yamato and Koushiro go on a camping trip to act as a cover for the other kids while they go into the DigiWorld to destroy it. The Kaizer unleashes Chimeramon, a genetically engineered Digimon made up of parts of other Digimon, but he has also included a portion of Devimon's dark data, and the powers of darkness corrupt Chimeramon, leaving Ken unable to control him. Chimeramon threatens to destroy the fortress on his own, but Wormmon leads Daisuke to the Digimental of Miracles, which Armour Evolves V-mon into Magnamon. Magnamon battles Chimeramon, but Wormmon is forced to sacrifice himself to make the Kaizer realise that Digimon are living things, and to give Magnamon the energy to destroy Chimeramon. Ken realises what he has done, and the Dark Seed deactivates, reverting him to his normal personality. The Digimental of Miracles reverts to the Crest of Kindness, which belongs to Ken.

Out Of Continuity
At some point during this time period, Chocomon, having become his Child form of Lopmon, frees himself from the dimension, and, in his Adult form of Wendimon, begins his search for Wallace. He captures six of the first eight Chosen Children (sans Takeru and Hikari), and brings them to the dimension, which reverses their aging, until they are as young as they were during the Greymon/Parrotmon battle. Chocomon realises that none of them are Wallace, and turns his attention to the other Chosen Children, who have encountered Wallace. He attempts to capture Takeru and Hikari on a train, but their D-3s protect them. He then attacks Daisuke and Wallace, but is beaten back by Fladramon and Galgomon. Then, at Summer Memory, in a huge final battle, he confronts the Armour Digimon in his Perfect form of Antieramon. Outnumbered, he again evolves into his Ultimate form of Cherubimon. It takes Angemon and Angewomon Evolving to their Ultimate forms of Seraphimon and Holydramon and releasing the Golden Digi-Eggs, which allow V-mon and Terriermon to become Magnamon and Rapidmon to save the day.

From September 2002 to December 2002
The kids return to school, and set about rebuilding the damaged areas of the DigiWorld. V-mon evolves into his natural Adult form of XV-mon.
Ken awakens from a pseudo-coma, with amnesia. He can barely remember his parents or brother, and returns to the DigiWorld, to be confronted with angry Baby 1 Digimon at Primary Village. There, he remembers the first time he came to the DigiWorld, and finds Leafmon - the reborn Baby 1 form of Wormmon.
At Oikawa's command, Archnemon moves to try and destroy the Chosen Children, using her powers to transform Dark Towers into unliving Digimon. The other Digimon manage to evolve to Adult to defeat her creations. When the reactor to the Kaizer's abandoned base threatens to explode, XV-mon and Stingmon Jogress Evolve into Paildramon to defeat Archnemon's Ookuwamon, and destroy the reactor. Archnemon then lures the Chosen Children to the Giga House, where she attacks them with an army of mind-controlled insect Digimon, and then, in a fit of rage, reveals her true, Digimon form. She is beaten in battle, but then saved by Mummymon.
Archnemon combined one hundred Dark Towers together to create BlackWarGreymon, but the leftover programs within the Towers combine, giving BlackWarGreymon a mind of his own, with thoughts and feelings. He turns on Archnemon, and seeks opponents to battle to test his powers.
Ken, Hikari and Miyako stumble into the World of Darkness again, but manage to escape.
BlackWarGreymon cannot understand the notion of having a heart, and encounters Agumon, who tries to help him understand. Meanwhile, Archnemon and Mummymon turn their attention to the Holy Stones, mystic objects, which keep the DigiWorld in balance - with the Dark Towers de-powered and unable to warp reality, they have to come up with another plan to weaken the barriers to allow Oikawa to enter the DigiWorld. BlackWarGreymon feels pain as the first Holy Stone is damaged, and makes it his mission to destroy them all. The barriers of the DigiWorld begin to weaken, and Digimon appear in the city of Kyoto, as BlackWarGreymon continues his rampage. When the last stone is located, Paildramon, Silphymon and Shakkoumon hold off BlackWarGreymon, while the kids try to move it with their D-3s. This frees Qinglongmon from his prison, and he explains most of what has been going on to them. BlackWarGreymon flies away, claiming that he is going somewhere "to disappear."

December 24th, 2002
Ken invites the other Chosen Children to his Christmas party, and they all happily accept. They all bring the Digimon partners of the older Chosen Children into the real world, to celebrate Christmas with them. Taichi, Jou, Koushiro and Sora got to Yamato's concert, while Daisuke, Miyako, Iori, Takeru and Hikari go to Ken's for his party. The fun is broken up when Archnemon brings a Control Tower to Earth, and opens a Digi-Port, allowing wild Digimon to come through. The Armour Digimon destroy the Tower, and then the Digimon evolve to take down the enemies.

December 25th, 2002
Koushiro discovers that Digi-Ports are opening all over the world, and calls on the Chosen Children to help him get in contact with other Chosen Children kids around the world. Daisuke and Ken, meanwhile, battle a Triceramon and Mummymon. Gennai arrives, and explains his plan of action, using one of Qinglongmon's Digi-Cores to restore the original eight Digimon's lost ability to evolve to Perfect, and also giving Paildramon the power to Ultimate-Evolve to Imperialdramon.
Imperialdramon, flying faster than the speed of sound, transports the twelve kids to six strategic locations around the world, where they team up with other native Chosen Children, as well as Gennai's clones, to round up the wild Digimon and send them back to the DigiWorld.
At the same time, in Japan, Archnemon and Mummymon, at Oikawa's command, go about making offers to children with problems (loneliness, sickness, etc), convincing them to come with them.
When all the wild Digimon are rounded up, Imperialdramon takes everyone back to Tokyo, in time to celebrate Christmas with their families.
In the evening, Taichi warns Hikari that the time will come when she and the other new Chosen Children will have to destroy a Digimon. Ken's memories of his time in the DigiWorld with Ryo begin to come back to the surface, when he dreams about the battle with Milleniumon and the Dark Seed.

December 26th, 2002
The Demon Corps appear in Tokyo, searching for Ken. The Chosen Children battle SkullSatamon, but he immobilises Imperialdramon and defeats the other Digimon, some of whom devolve due to being in the real world for so long. The original eight Digimon (sans the absent Palmon) give their power to Imperialdramon, enabling him to Mode Change to his Fighter Mode and destroy SkullSatamon.
Archnemon convinces Ken to come with her, saying she will release all the 'kidnapped' children if he does so. He agrees and is taken away in a truck, where he meets Oikawa, who explains to him about the Dark Seed within him. Oikawa copies Ken's Seed, and implants it into the other children at their own request. The kids know the Seeds will enhance their abilities, while Oikawa plans to use them to convert the innocence of the children into an energy he can use to enter the DigiWorld. Their true purpose, however, is to provide power for Vamdemon, to allow him to be born again.
Meanwhile, Daisuke pursues the truck, and the other Chosen Children are forced to destroy the other members of the Demon Corps to protect the city. At Hikarigaoka, their leader, Demon, appears, and demands that Ken be handed over to him. Oikawa, having got what he wanted, is ready to comply, but Daisuke busts up the transaction. The Digimon all team up against Demon, and Ken uses the energy within the Dark Seed to open a gate to the World of Darkness, through which Demon is sent. Oikawa tells the children to remember Hikarigaoka, and then flees. The children are returned to their parents.

Agumon and co. return to the DigiWorld to discover some serious destruction, courtesy of the returned BlackWarGreymon. Qinglongmon bestows more power on Agumon, restoring his power to Warp-Evolve.

December 27th, 2002
The Dark Seeds begin their work, enhancing the capabilities of the children. The Chosen Children begin to watch them closely, studying the effects of the Seeds, with help from some of their parents.
Oikawa, Archnemon and Mummymon hide out on Mount Fuji, but BlackWarGreymon arrives on Earth, with intent to destroy them all.

December 28th, 2002
BlackWarGreymon attacks Oikawa, Archnemon and Mummymon, realising that Oikawa is his creator, as Oikawa created Archnemon, who in turn created him. Taichi and Hikari intervene, and Agumon becomes WarGreymon to battle with BlackWarGreymon, defeating him with help from Imperialdramon. BlackWarGreymon leaves again, to think on what they have told him about life and friends.

December 29th, 2002
The Dark Seed of a girl named Noriko is about to flower prematurely, and Oikawa has to move to absorb its power before the Chosen Children get to her first. He encounters Iori, and recognises his surname, identifying him as Hiroki's son. He visits Hiroki's grave, and reflects on the past.

December 30th, 2002
Noriko's Seed flowers, and Oikawa absorbs its energies. The dark power energises Vamdemon, who holds Oikawa's mind back when Iori's grandfather offers him his hand in friendship. BlackWarGreymon is fatally injured protecting Iori's grandfather from Oikawa/Vamdemon, and uses the last of his strength to seal the Hikarigaoka DigiWorld gate with his body.

December 31st, 2002
Oikawa calls the children back to Hikarigaoka, where he attempts to open a gate to the DigiWorld. Instead, a portal to the dream dimension opens, through which Oikawa unwittingly travels, followed by the children, Archnemon, Mummymon and the Chosen Children. In the dimension, Vamdemon vacates Oikawa's body, and uses the energy from the flowered Dark Seeds to transform himself into BelialVamdemon. He uses the powers of the dimension to create illusions of all the Chosen Children's greatest desires, but Daisuke wins through, and helps free the others. Then, they use the power of the dimension to their own ends, making all their Digimon evolve to their separate forms at once, and teaming up on BelialVamdemon.
The villain flees into the DigiWorld, and absorbs the darkness already there into his body, increasing his power. He begins to initiate the spread of darkness over Earth, when all the Digimon of the world's Chosen Children arrive to confront him. Acting as beacons, the bond between them and their human partners opens Digi-Ports all over Earth, bringing the Chosen Children into the DigiWorld. Using the power of their dreams, and belief in themselves (through which the Dark Seed children become Chosen Children themselves), BelialVamdemon's darkness is repelled, weakening and discorporating his body. His dark spirit tries to spread, but Imperialdramon's Giga Crusher attack destroys it, apparently for good.
Gennai returns Tailmon's Holy Ring, and Oikawa meets his Digimon, Pipimon. However, Oikawa has lost too much energy, and his body is too weak to go on. Using the power of the dream dimension, he fulfils a wish of his own, transforming his body into energy, which spreads across the DigiWorld, restoring the tranquillity that was almost destroy by Vamdemon's darkness.

March 2003
It transpires that Diablomon was not completely destroyed during the battle in the year 2000. Yamato and Taichi venture into the Internet again with Omegamon to destroy him, but he escapes to the real world in the form of a huge swarm of Kuramon. Once on Earth, the Kuramon merge together to form Armagemon, a huge, alternate Ultimate for their line that is more powerful that Diablomon ever was.
