Fan:The Great Collision

Prologue
After the defeat of Ordinemon the four DigiDestined of 02 season, Daisuke, Ken, Miyako and Iori, receive the visit from Koushiro Izumi, who gives them their old D-Terminals that he has found in a old box on his office, saying that he will deliver the other eight D-Terminals to the other 1999's DigiDestined when they will met all together. For the curiosity of read his old messages, Daisuke opens his old D-Terminal and discover a notification that says “The objects were sent successfully”. Furthermore he find out that there are no more his three Digi-Eggs of Courage, Friendship and Miracles. The same discoveries are made by Miyako and Iori and Ken says to them that maybe this phenomenon is related to the reboot of Digital World. After the four are discharged from the hospital, they immediately open a digigate and come back to the Digital World in order to recover their partners. They arrive in front of a temple that reminds them of the one in which Miyako and Iori found their respective Digimon. Upon entering the temple, they find the Digi-Eggs of Miracles, Kindness, Destiny and the new Digi-Egg of Joy positioned on four altars and in front of them were the corresponding Crests in their Tags. Each of the four wears his own Tag and lifts the corresponding Digi-Egg: Daisuke that of Miracles, Ken that of Kindness, Miyako that of Joy and Iori that of Destiny. Once the Digi-Eggs are lifted, the four partners appear in front of the DigiDestined, but a sudden earthquake forces them to immediately return to the real world through the digigate. Returning in the real world the Digi-Eggs and the Crests are stored in the D-Terminals. The four DigiDestined, along their partners, goes to Koushiro to report what they discovered and opening his own D-Terminal Koushiro find out that now he owns the Digi-Egg of Knowledge, that before belonged to Iori. In order to investigate what is happening in the Digital World, Koushiro contacts the other seven DigiDestined and give them their old D-Terminals. All together the twelve DigiDestined enter in the Digital World through a new digigate opened by Miyako, but once in the Digital World, the Four Sovereign Digimon present themselves claiming that the Digital World is in grave danger and to contain this threat they will need the energy of the DigiDestined. At this point Azulongmon absorbs a beam of light departed from the Digivice of the twelve DigiDestined, making the four D-3 Digivice regress to the normal Digivice stage. Azulongmon states that without this energy the DigiDestined are too weak, so it sets out to send them back to their world. To prevent this from happening, Tailmon uses much of its energy, regressing to the state of Plotmon permanently. Thus the DigiDestined manage to stay in the Digital World, but find themselves scattered in pairs.

Troubles in Digital World
Miyako recovers from fainting next to Hikari and recognizes what remains of the temple where she was able to re-embrace Hawkmon. However, a black obelisk now stands in the ruins of the building guarded by a Tyrannomon and a DarkTyrannomon, which wear a Dark Ring and have a Black Gear stuck in their backs. While Miyako realizes that the obelisk's emergence must have caused the earthquake that destroyed the temple, Hikari points out that Koushiro had said one last cryptic sentence before they were scattered: «check your D-Terminals». In that moment the two girls are caught off guard by a Goblimon, a SnowGoblimon and a Shamanmon, also wearing a Dark Ring and a Black Gear in their back. At the same time Ken, in the company of Daisuke, discovers a group of Kuwagamon guarding a greenhouse where the Dark Spores are cultivated. It seems that some of these have blossomed, giving birth to Dark Flowers and even some of these have grown into Dark Trees. Ken convinces Daisuke to destroy the greenhouse, because whoever is growing those evil plants certainly has no good intentions. However, the two boys find a Deltamon, also under the control of a Dark Ring and a Black Gear, blocking their way. At this point Daisuke tells Ken to go ahead while he keeps the guard busy: Daisuke makes armor digivolve Veemon to Magnamon and confronts Deltamon. Ken enters the greenhouse, but is immediately attacked by the Kuwagamons, so he attempts to unsuccessfully digivolve Wormmon to champion its level. Fortunately Ken remembers that he is now in possession of the Digi-Egg of Kindness and makes armor digivolve Wormmon to Bucchiemon for the first time. With the help of their Digimon, Ken and Daisuke destroy the Dark Rings and Black Gears, and then raze the greenhouse with all the plants inside. But just at that moment they realize that on the hill overlooking the greenhouse stands a black obelisk.

Taichi and Yamato recover in a village inhabited by peaceful Digimon, who claim to be constantly attacked by the inhabitants of the neighboring village. The latter have suddenly begun to behave violently since a huge black obelisk appeared in their square. Most of the community would like to leave the village, but two young Digimon, Flamemon and Strabimon, insist on fighting and repelling the attackers. Just then a Monochromon and a Growlmon, also under the influence of Dark Rings and Black Gears, begin to wreak havoc on the village, causing Flamemon and Strabimon to react quickly. However, the two young Digimon are quickly defeated and Taichi and Yamato decide to intervene, but their partners are unable to digivolve. At that point, remembering Koushiro's words, Taichi and Matt control their D-Terminals and they discover inside them the Digi-Egg of Courage and the Digi-Egg of Friendship, thanks to which Agumon armor digivolves to FlameGreymon and Gabumon to RaiGarurumon. FlameGreymon saves Flamemon by destroying the Dark Ring and Black Gear which made Monochromon furious, while RaiGarurumon does the same by defeating Growlmon to protect Strabimon. The digivolution of Agumon and Gabumon reactivates the memory of Flamemon and Strabimon. They are the only two survivors of an ancient group, the Ten Legendary Warriors, who fought alongside the Seven Holy Digimon, of which only two members remained, in an ancient war fought against the Seven Great Demon Lords and the Dark Masters, at era led by Apocalymon. The forces of light managed to seal off some of the Great Demon Lords and exile various evil Digimon in other dimensions, outside of the Digital World, but were unable to defeat the Dark Masters, which necessitated the intervention of the Original DigiDestined. Flamemon and Strabimon claim that no other of the Legendary Warriors survived, but the sacrifice of five Holy Digimon allowed their spirits to reincarnate into new Digimon who will choose to take their place in order to defend the Digital World. Taichi and Yamato ask for more details on the new eight warriors and how their powers should be awakened, but Flamemon and Strabimon say they don't know why they themselves have only awakened now and do not remember how the new Legendary Warriors will gain their powers. For the moment Taichi, Yamato, Agumon and Gabumon decide to be accompanied by Flamemon and Strabimon to the nearby village to free it from the influence of the black obelisk.

Sora wakes up on a bed, in a small house, looked after by a Digimon whose appearance resembles a fairy: Tinkermon. At that moment Mimi bursts into the room, saying that she is happy that Sora has woken up and that she has tried to contact the others, but her phone does not work. So she Mimi she claims she took Koushiro's advice and checked her if she could communicate with her old D-Terminal, but that doesn't seem to work either. At that point Sora asks Tinkermon which area of ​​the Digital World they are in, but Tinkermon replies that that is the Primary Village, capital of Never-Ever Land, a dimension inhabited by little Digimon and that it doesn't even know what the Digital World is. At that moment, Petermon, companion of Tinkermon, also bursts into the room, who states with concern that those strange large and dangerous Digimon coming from the great black obelisk are back. Head outside, Sora and Mimi find a Mojyamon leading a troop of Numemon and all of them are under the control of Dark Rings and Black Gears. Sora and Mimi unsuccessfully attempt to digivolve Piyomon and Palmon to defend the Fresh Digimon. At that point Mimi checks again if she with the D-Terminal she manages to contact the other DigiDestined, but Sora senses that perhaps Koushiro meant something else and she discovers that she possesses the Digi-Egg of Love, thanks to which Piyomon armor digivolves to Thothmon, leaving Tinkermon, who never see a digivolution, in awe. Mimi does the same and causes Palmon to armor digivolves to Ponchomon thanks to the Digi-Egg of Purity. Thotmon manages to defeat Mojyamon by destroying its Dark Ring and Black Gear, while Mimi frees the Numemons. Sora decides to question Mojyamon in order to understand what is happening. The latter replies that their goal was to prevent any interference with the activities of a mysterious nearby base, to which Sora and Mimi ask to be accompanied. Tinkermon decides to join them and as Ponchomon, aided by Mojyamon and the Numemon, creates a diversion outside, Sora, Thotmon and Tinkermon sneak into the base as its guards rush out. Inside, Sora's D-Terminal begins to emit an intermittent signal, which the three instinctively decide to follow, reaching the control center of the base. The power source reacts to Sora and it's stored in her D-Terminal and at that moment, Mimi, who is still compulsively trying to use her D-Terminal to communicate, notices that the interference appears to have diminished. The three try to escape from the base, but their way is blocked by a Wendigomon, who defeats Thotmon by surprise, so Tinkermon tries to protect Sora. Tinkermon is weak, but in that moment the source of power that Sora has stored in her D-Terminal causes Tinkermon to digivolve to Kazemon, which defeats Wendigomon and takes Sora and Piyomon off the base. Sora, Mimi, Palmon, Piyomon and Kazemon return to Never-Ever Land and from there they decide to go and destroy the black obelisk that threatens Primary Village, but in the meantime they manage to witness the digivolution to Pomumon of a Datirimon held in Petermon's arms.

Koushiro and Jō find themselves in a forest and after having verified and after having verified that it is impossible to communicate, they look for a way out, coming across a black obelisk located in the center of a lake island. Koushiro would like to fly over the area with Kabuterimon to recon, but Tentomon, just like Gomamon, is unable to digivolve. Koushiro senses that the black obelisk is responsible for both interference and the Digimon's inability to reach champion level; also, he remembers the fact that the Control Spire acted as repeaters, so he devises a plan to establish communication. At Koushiro's request Jō uses the Digi-Egg of Sincerity, causing armor to digivolve Gomamon into Desmomon, allowing them to reach the island. However, as they are about to land on the island, the group is attacked by a Seadramon, who is confronted by Desmomon. Arrived on the island, Koushiro makes armor digivolve Tentomon to Ballistamon, who manages to defeat a Cyclonemon guarding the obelisk, being amazed that it is under the control of different devices, used by different enemies, which they have faced at different times. Ballistamon destroys the obelisk and Koushiro asks Jō and Desmomon to watch his back as he carries out his plan. Trusting that his friends would instinctively destroy the obelisks, he makes sure that as soon as this occurs, a signal goes out from the base of the obelisk: «Listen and wait for instructions». Takeru and Iori are on a mound, from which they notice the presence of a black obelisk nearby. However the hill is surrounded by a pack of Fangmon controlled by Dark Rings and Black Gears. Unable to spawn Angemon, Takeru causes armor to digivolve Patamon to Pegasmon in order to fight the Fangmon. At that moment, a swarm of Snimon attacks the two boys from above, but Iori manages to fend them off using the Digi-Egg of Destiny to make armor digivolve Armadillomon to Kenkimon. Defeated the attackers, Takeru and Iori instinctively order Kenkimon and Pegasmon to destroy the black obelisk, thus receiving the message from Koushiro's tablet in their D-Terminals. Hikari, Miyako, Plotmon and Hawkmon are captured by Goblimon and its fellows which take them near the black obelisk, where they are attacked by the Tyrannomon and DarkTyrannomon. At that point Miyako uses the Digi-Egg of Joy to make armor digivolve Hawkmon to Huginnmon, which confronts and defeats Goblimon, SnowGoblimon and Shamanmon. So does Hikari, who make armor digivolve Plotmon into Nefertimon, which it puts Tyrannomon and DarkTyrannomon on the rug. So the two girls instinctively have their partners destroy the black obelisk too, receiving Koushiro's message in their D-Terminals. Taichi and Yamato do the same thing together with FlameGreymon, RaiGarurumon, Flamemon and Strabimon; as well as Sora and Mimi together with Thothmon, Ponchomon and Kazemon. Finally, also Daisuke and Ken, once reached, have their partners destroy the black obelisk closest to them, obtaining the possibility to get in touch with the others through the D-Terminals.

The Digital World is occupied
Having managed to connect with everyone, Koushiro says he is sure that the black obelisks are responsible for blocking communications and the inability to digivolve at Champion level and that they are probably just repeaters of a signal from somewhere else. Miyako adds that she is absolutely sure that they suddenly appeared. Sora and Mimi tell about the base they destroyed, its connection to interference and its mysterious source of energy. Furthermore, Sora says that according to the Digimon Analyzer Tinkermon should have digivolved to Darcmon, but the mysterious source of energy make it to digivolve to Kazemon. Flamemon and Strabimon recognize Kazemon as a form of one of the Ten Legendary Warriors and the artifact that awakened it as one of the "spirits" generated by the sacrifice of the Holy Digimon; additionally, Patamon and Plotmon are recognized as the two surviving Holy Digimon. Ken states that it makes sense to use an ancient artifact of light as a source of energy for something dark, as he did when he played the role of the Digimon Emperor; however, he's very concerned about the cultivation of Dark Spores, because he knows how dangerous they are. Koushiro resumes saying that he is amazed that the Digimon who attacked them were under the control of such different black artifacts and that he believes it is essential to understand who is behind what is happening. Therefore, Koushiro installs in their D-Terminals a location algorithm that he had already worked on, saying that he modified it while waiting for everyone to connect, so that he had a tool to track the position of the obelisks and, once that these will be destroyed, even of the source of their signal, as well as increase the range within which the D-Terminals react to the Digi-Spirits. So the DigiDestined decide to go in search of the obelisks and the Digi-Spirits, hoping to also meet the new Legendary Warriors. As soon as the conversation ends, Takeru and Iori are joined by Impmon, a Rookie Digimon who claims to come from the village next to the black obelisk they just took down. Impmon asks them to follow it because its home has been attacked by unknown Digimon and that only they can help them. Takeru and Iori arrive in the middle of a forest, in an uninhabited place haunted by some species of Rookie Digimon. None of these appear in the Digimon Analyzer and Impmon calls this species "Algomon", "Arcadiamon", "Gizumon" and "Soundbirdmon". Takeru and Iori order Pegasmon and Kenkimon to attack, but while they are destroying their enemies, Takeru and Iori realize with horror that that wood is made up only of Dark Trees laden with fruits, from which Algomon, Arcadiamon, Gizumon and Soundbirdmon seem to emerge. At that moment Impmon begins to laugh at them and begins to feed on the data of the destroyed Digimon until it warp digivolve to Beelzemon, mocking the DigiDestined for not realizing it was one of the Seven Great Demon Lords, the enemies they have long been looking for, but at the same time it is amazed that their twelve were not imprisoned and even entered the Digital World. After it finishes speaking Beelzemon attacks them, but fortunately, the light from the Crests protects Takeru, Iori, and their partners from complete destruction, but the blast wave of the blow throws them away from where they were before. Upon awakening Takeru realizes that he has been rescued by their old friend Leomon, who is accompanied by Ludomon, Spadamon, Zubamon. Shortly after, Iori arrives who has instead been rescued by Ogremon, who arrives together with Fugamon, Hyogamon and some Peckmon. Leomon asks if the two boys were attacked by the artificial Digimon, so Takeru asks it if it's referring to Algomon, Arcadiamon, Gizumon and Soundbirdmon. Leomon confirms that they are the artificial Digimon and that they are harvested through the Dark Trees. Takeru states that the artificial Digimon were accompanied by one of the Seven Great Demon Lords, but Leomon is amazed, because it knew the Dark Trees were grown by what they call themselves the New Dark Masters. The explosion caused by Beelzemon caught the attention of Miyako and Hikari, who felt it from a great distance. Thus, the two girls, arriving in flight thanks to Huginnmon and Nefertimon, find Takeru and Iori in the company of Leomon and the other Digimon of its group.

The Firts Spirits
As soon as the conversation ends, both the couple formed by Taichi and Yamato and the one composed by Daisuke and Ken decide to separate because their D-Terminals point in different directions. Taichi, Flamemon and Agumon reach the destination indicated by the D-Terminal: an enemy base near a black obelisk. The three are attacked by a group of Tankmon, then Agumon armor digivolves to FlameGreymon to face the enemies, but is in a strong minority. So it invites Taichi to accompany Flamemon to the base because only with its help will it be able to win the battle. Flamemon breaks through the base wall in a desperate attempt to avoid the enemies and reach the Spirit as soon as possible. The two manage to reach the reactor, but are surrounded by a group of Troopmon. At that point what Flamemon calls the H Spirit of Flame is stored in Taichi D-Terminal. Then Taichi uses it to digivolve Flamemon to Agunimon, who manages to make its way through the Troopmon just in time to defeat the Tankmon along with FlameGreymon and destroy the black obelisk. Then flee far away, before the enemies regroup. Takeru and Iori tell Hikari and Miyako what they discovered about their enemies, so Takeru and Hikari decide to investigate together the identity of the mysterious New Dark Masters, while Miyako and Iori decide to join in the search for the Spirits, as their D -Terminals point in the same direction. Quickly transported by Huginnmon, Miyako, Iori and Armadillomon cross paths with Koushiro and Jō. After updating their friends about the identities of their enemies, the four decide to reassemble the pairs according to the direction in which the D-Terminals are pointing: Koushiro will go with Iori, while Miyako will go with Jō. Along the way Koushiro and Iori notice a sudden increase in interference and in the thick of a forest they meet Yamato, Gabumon and Strabimon, who tell them that they have separated from Taichi, Agumon and Flamemon and have discovered that there is a very large base in the area, flanked by even two obelisks, which seems to emit much more intense interference than they have ever seen up to that moment. This fact leads Koushiro to hypothesize that there may be more than one Digi-Spirit inside. While they are still arguing, the boys are surprised by a noise: in the vegetation a Monmon is captured by a Black Gear and a Dark Ring, which cause it to digivolve to Apemon. Apemon realizes their presence and surprisingly kidnaps Iori, disappearing among the branches. Imagining that it has brought him to the base, the group follows the interference to find Iori. However, along the way they are attacked by KoKabuterimon, a forest dweller who mistook them for base guards. Having discovered their identity, KoKabuterimon chooses to help the boys and their partners by leading them to the base. So Koushiro thinks of a plan to save Iori and recover the Spirits: KoKabuterimon wreaks havoc outside the base, while RaiGarurumon, taking advantage of its incredible speed, knocks several enemy Digimon into some traps previously dug by Armadillomon. Thanks to the small number of enemies still inside, Yamato, Koushiro, Strabimon and Ballistamon penetrate without too much difficulty into the base and reach its center, where inside are those that Strabimon recognizes the H Spirit of Light, stored by Yamato's D-Terminal, and the H Spirit of Thunder, stored by Koushiro's D-Terminal. Thanks to the H Spirit of Light Strabimon digivolves to Lobomon and helps the boys to free Iori. Once out of the base Iori makes armor digivolve Armadillomon to Kenkimon, but at that moment Apemon appears again accompanied by a Grizzlymon and a group of Waspmon. Being in a strong minority, RaiGarurumon, Lobomon and Kenkimon struggle to keep up with all the enemies and KoKabuterimon, eager to help them, surprisingly digivolves to Beetlemon thanks to the H Spirit of Thunder. Using a strong electric shock, RaiGarurumon and Beetlemon free all the Digimon from the Black devices, while Lobomon and Kenkimon destroy the two black obelisks. After the battle, Koushiro and Iori, accompanied by their partners and Beetlemon, decide to continue on their way saying they are sure to meet everyone again soon.

The Datamon's Lab
Ken also finds himself in the great forest and together with Wormmon is trying to locate the base from which the signal received from his D-Terminal comes from. At that moment the two notice a Vilemon hiding in the vegetation. Without letting their guard down, the two partners approach it asking what it is doing there, but the latter, frightened, replies to them that it has escaped from the base where the large black obelisk is located, however it is worried, because many of its friends are still prisoners and it knows that there is a Datamon conducting horrible experiments. Moved with compassion by Vilemon's words, Ken decides to help it and, using Bucchiemon's power, the three reach the base and infiltrate it making fall asleep both the guards outside and those they meet inside. Finally, arriving in a large room full of strange machinery, inside which Datamon is located, they pass out from a sudden electric shock. When Ken awakens, he discovers that he and Wormmon have been imprisoned by Datamon, who needed Ken to conduct an experiment, and that Vilemon had been in league with Datamon from the start and only told them lies to lure them there. Datamon reveals to Ken that its Masters had already used the Spirits, described as incredible sources of energy, to power their Containment Field. However, Datamon claims that the Black devices that have been applied to it have expanded its knowledge and understanding, therefore it has managed to understand that the true power of the Spirits can only be extracted thanks to the DigiDestined they are linked to. To test its theory, Datamon got hold of the two Spirits of Darkness and set the trap for the DigiDestined they were destined for, knowing that the latter would join them spontaneously. Datamon shows Ken the two Spirits of Darkness, which begin to shine in reaction to the presence of him and his Digivice and D-Terminal, which had been seized from him by Datamon, who needed them for its experiment. At that point Datamon extracts their energy by creating two corrupted copies: from the H Spirit of Darkness it creates the L Spirit of Darkness, while from the B Spirit of Darkness it creates the K Spirit of Darkness. Eager to test its potential on one of its captives, Datamon uses the power of the K Spirit of Darkness to digivolve a Vorvomon to Velgemon, which is under the control of Datamon even if it is not wearing Black devices. It then prepares to do the same thing with the L Spirit of Darkness using a Tapirmon as a guinea pig, but at that moment Ken decides to react: he causes armor to digivolve Wormmon to Bucchiemon, which frees its partner and Tapirmon. Then Ken stores the Spirits of Darkness in his D-Terminal and the three flee the base. Datamon is furious at losing its lab animal, but Vilemon volunteers for the experiment and Datamon uses the L Spirit of Darkness to digivolve it to Duskmon. Then Datamon orders Duskmon and Velgemon to chase the fugitives and gives them as support a pack of Digimon made up of several Psychemon and Gazimon placed under the control of the Black devices. Ken, Bucchiemon and Tapirmon are joined by their enemies as soon as they are off the base. Ken would like to escape, but Tapirmon claims that it wants to fight and surprisingly the H Spirit of Darkness makes it digivolve to Loweemon. Overconfident, Loweemon confronts numerous enemies, but ends up being overwhelmed and a furious Gazimon and Psychemon bite it, causing it to lose data that allows them to digivolve to Sphinxmon and Gururumon respectively, while Loweemon degenerates to Tapirmon. Ken then orders Bucchiemon to create a diversion while he recovers Tapirmon. So the three flee back into the forest chased by the enemies.

The Great Train Robbery
Sora and Mimi, accompanied by their respective partners and Kazemon, chase the signal from the latter's D-Terminal, which leads them to a desert area. However, the excessive heat causes the girls and Palmon, who were flying thanks to Thothmon, to land and take refuge in a cave. There they discover a group of Digimon, led by Neemon and Bokomon, who are taking care of exhausted Daisuke and Veemon. Neemon says that it found them dehydrated from the desert heat and saved their lives. Daisuke confesses that he was reckless, but begs Neemon to tell his friends what it has already told him. Neemon says that the area was once lush, but the Seven Great Demon Lords have built a factory that has dried up all resources and desertified everything. In addition, it says that Leomon's spies have confirmed that three powerful artifacts needed to provide the energy to "build a prison" have recently been transported to the factory. But obviously that wasn't enough, as Leomon has discovered that two more artifacts are about to reach the factory aboard a Trailmon. Thus, Daisuke proposes an assault on the train worthy of a movie. Sora, Mimi, Piyomon, Palmon and Kazemon obviously accept Daisuke and Veemon's proposal and Neemon, after recommending them to be careful, warning them of the fact that guards are present everywhere, asks Deputymon to accompany them to the railway. Arriving at a level crossing manned by a Black obelisk, Deputymon and Kazemon create havoc on the rails to slow down Trailmon a bit, Sora and Thothmon leave Daisuke and Mimi, with their respective partners, on the roof of the wagons from which the signals of their respective D-Terminals come. Mimi finds the H Spirit of Wood in her wagon that is guarded by a Vegiemon, a RedVegiemon and a Weedmon. While Ponchomon distracts the three Vegiemon by putting on a musical curtain, Mimi stores the H Spirit of Wood and exits the wagon again unnoticed, then Ponchomon also exits the wagon without a shot being hurt after inducing the Vegiemon to argue with each other. Daisuke and Veemon also enter their wagon, but the H Spirit of Steel is protected by a Shoutdramon who attacks them. Daisuke makes armor digivolve Veemon into Magnamon, who with a little difficulty manages to knock out Shoutdramon, allowing Daisuke to store the H Spirit of Steel in his D-Terminal. Once the operation is complete, Thothmon and Sora retrieve Mimi, Palmon, Daisuke and Veemon, while Kazemon takes Deputymon away, then all of them return to Neemon's refuge. There the DigiDestined claim they want to break into the factory as well, but Neemon advises them to go undercover and trust one of Leomon's spies in the factory; in addition, it assigns Aruraumon the task of accompanying them to the factory.

The Mine and the Ghost City
Koushiro, Iori and Beetlemon, following the signal of the D-Terminal of the second, arrive in a mountainous area where there is a mine, above whose entrance stands a black obelisk. The mine tunnels are excavated by a Drimogemon and a NiseDrimogemon, while the debris is carried away by a large number of Gotsumon, Meteormon and Icemon. Outside the mine there is a Golemon who appears to act as an overseer, but all the Digimon employed are enslaved by Black devices. Since the signal seems to come from inside the mine, the two boys implement a very simple plan to infiltrate it: Kenkimon will enter the workers as a "digging machine" wearing fake Black devices, so it will be able to recover the object they are looking for undisturbed. The ruse succeeds, but Kenkimon, after talking with one of the Gotsumon, discovers that the work on the mine has begun precisely to find a mysterious source of energy hidden underground, which is indispensable for the realization of the plans of the New Dark Masters. Understanding the unattainability of the plan's final objective, Koushiro attempts a coup by causing Ballistamon and Beetlemon to destroy the black obelisk, which triggers the immediate uprising of the Digimon miners, who help Kenkimon and Iori take away from inside the mine the B Spirit of Earth which is stored in Iori's D-Terminal. The Digimon miners say they want to carry out the protest by knocking down the furnace on which the mine depends. So Koushiro, Iori and Beetlemon decide to follow them, because their D-Terminals point precisely in that direction. The industrial complex of the furnace consists of two buildings: the blast furnace and the power plant that powers it. Iori and Kenkimon, accompanied by the Gotsumon, the Icemon and the Meteormon, break into the blast furnace, which is powered by the H Spirit of Earth that is stored in Iori's D-Terminal. Instead, Koushiro, Ballistamon and Beetlemon enter the power plant, but between them and the B Spirit of Thunder there is a very large troop of Pulsemon controlled by Black devices. To their rescue come Drimogemon, NiseDrimogemon and Golemon, who defeat Pulsemon and allow Koushiro to store the B Spirit of Thunder in his D-Terminal. However, as soon as the two DigiDestined recover their Spirits, the doors of the buildings snap shut, causing anyone inside to fall into a trap. At that point Kimeramon appears in front of Koushiro, while Mephistomon appears in front of Iori.

Taichi, Agumon and Agunimon follow the signal from the D-Terminal to what looks like a real contemporary city, complete with skyscrapers and a subway. However, the city is deserted and the three enter a theater, inside which they find the B Spirit of Flame, which Taichi is preparing to store in his D-Terminal. However, just at that moment a hologram of Myotismon appears, who proves incredulous at the idea of ​​having seen Taichi again after its rebirth, especially because he should have already been a prisoner. Then it adds that the collection of Spirits will not benefit the DigiDestined, because even if it was not foreseen and forced them to change their plans, the presence of the DigiDestined in the Digital World allowed them, the New Dark Masters, to steal the "secret of digivolution". After Myotismon's speech, a ToyAgumon controlled by Black devices appears in the audience, which digivolves first to Omekamon and then to Etemon, while a DoruGreymon appears on stage to protect the Spirit. Taichi bravely rushes to the stage to steal the B Spirit of Flame, but in doing so is about to be hit by DoruGreymon. Agumon armor digivolves to FlameGreymon to protect its partner, while Agunimon clashes with Etemon. However, both Digimon accompanying Taichi are about to have the worst, but the latter manages to store the B Spirit of Flame in his D-Terminal, which suddenly activates causing the digivolution of Agunimon to Aldamon and of FlameGreymon to BurningGreymon. The two Ultimate Digimon manage to defeat their opponents and flee the ghost town together with Taichi. After flying for a long time, the three decide to take refuge in the forest which they find themselves flying over.

Troubles around the Digital World
Yamato, RaiGarurumon and Lobomon run away from the base where they recovered the B Spirit of Light being chased by a Megadramon and a Gigadramon, which shortly before they had seen digivolving by two Airdramon controlled by Black devices, and by a Tankdramon they decide to take refuge in the forest. Meanwhile Ken and Bucchiemon are having a conversation with Tapirmon, who explains to them how he ended up in Datamon's laboratory. Tapirmon tells that it wanted to digivolve at Champion level, perhaps to a mighty Baluchimon, to face the evil Digimon who are occupying the Digital World and are enslaving anyone who has not already surrendered through the Black devices. Tapirmon used to share its dream with its friends: a Shamanmon, who wished to digivolve to Fugamon, and a SnowGoblimon, who wished to digivolve to Hyogamon. Unfortunately both were captured and Tapirmon remained one of the last Digimon still free when it was approached by Vilemon, who convinced it that it could acquire the power to fight with the help of Datamon, but the truth was very different. While the three are still conversing, Yamato, RaiGarurumon and Lobomon emerge from the vegetation and shortly afterwards the enemies from which the DigiDestined were trying to escape also burst onto the scene: Duskmon, Velgemon, Sphinxmon, Gururumon, Megadramon, Gigadramon and Tankdramon. Thanks to the H Spirit of Darkness Tapirmon digivolves once again to Loweemon. Thus, RaiGarurumon battles Sphinxmon and Gururumon, Lobomon confronts Tankdramon, while Loweemon battles Duskmon and Velgemon. Also, in the middle of the battle Megadramon and Gigadramon kidnap Bucchiemon and take it away from its companions. At that point, Yamato's will to protect his friends activates the B Spirit of Light which causes the digivolution of Lobomon to BeoWolfmon and of RaiGarurumon to KendoGarurumon; at the same time the B Spirit of Darkness is activated which causes Loweemon to digivolve to Rhihimon. The three Ultimate Digimon manage to defeat and free their respective opponents. Once Velgemon and Duskmon are defeated, they regress to Vorvomon and to Vilemon and the latter runs away. At that moment Taichi arrives from above, who is in the company of Bucchiemon, BurningGreymon and Aldamon, who have defeated Megadramon and Gigadramon.

Thanks to a suitable disguise, Sora, Mimi, Daisuke, Piyomon, Palmon, Veemon, Kazemon and Aruraumon sneak into the factory led by an Hagurumon, Leomon's spy. The Black Gears and Dark Rings are produced in the factory and a large number of Hagurumon, Guardromon and Andromon work inside, all of them enslaved by Black devices. Hagurumon leads the DigiDestined and their group into the generator room that powers the factory, which runs on the B Spirit of Wind, B Spirit of Wood, and B Spirit of Steel. But while the three DigiDestined are about to store their respective Spirits, NeoDevimon reveals that it has always been hiding in the room to set a trap for them. NeoDevimon tells them it is amazed to see DigiDestined again after File Island's events, but this time they will not escape them, the New Dark Masters; then it orders a group of Andromons to capture the intruders. At that moment the H Spirit of Wood and the H Spirit of Spirit of Steel are activated causing the digivolution of Aruraumon to Arbormon and of Hagurumon to Mercurymon, respectively. They manage to distract enemy Digimon long enough for DigiDestined to store the Spirits in their D-Terminals, but the situation remains desperate.

While the other DigiDestined were busy searching for the Spirits, Takeru and Hikari began actively searching for and destroying the black obelisks with the help of Pegasmon and Nefertimon. However, after destroying a large number of obelisks, Dagonmon, the ruler of the Dark Ocean, appears in their path. Dagonmon says that it is amazed that the DigiDestined have not been imprisoned in Never World like the all other Tamers, but at the same time it claims to have come to free themself from the annoyance that the two represent for it and its colleagues, the New Dark Masters. However, it sarcastically thanks them because their presence has allowed the New Dark Masters to extract the true power of the Spirits and to understand how to induce digivolution even in the presence of the Containment Field. Hikari asks to it how it went out from the Dark Ocean in which it was confined and Dagonmon replies that the feud between Homeostasis and King Drasil that led to the reboot allowed all parallel dimensions to collide with the Digital World, exactly as it was before the Ancient War. In particular, the Dark Ocean has reunited with the Ocean's sector and from it Dagonmon has propagated his power to inhibit digivolution through the black obelisks. Furthermore, the collaboration with the other four New Dark Masters allowed it to use the Black devices: the Dark Rings to subdue the Digimon and the Black Gears to upgrade and corrupt them. Finally, after many experiments, the New Dark Masters have discovered how to cultivate Artificial Digimon from the Dark Spores, which will be the ideal army to enslave the real world. Not even finished the speech, Dagonmon attacks Takeru and Hikari.

Ice Fortress
Jō and Miyako and their partners, following the signal of their D-Terminals, reach the shore of the Ocean's sector, which is heavily polluted. On board of Desmomon, Jō, Miyako and Hawkmon cross the open sea where they find a debilitated Penguinmon, who is pulled aboard so that Jō can help him. Once recovered, Penguinmon tells them that Dagonmon has built an immense ice fortress, the base of which rests on the ocean floor. The fortress seems to be connected to the black obelisks that infest the Digital World and from it the poisonous influences of the Dark Ocean that are poisoning the Ocean's sector spread. Miyako asks if that's where the Spirits are, but Penguinmon claims it doesn't know what they are. While still talking to each other, the five are attacked by a Coelamon and an Ebidramon, who are led by an arrogant Jellymon and are all controlled by Black devices. Desmomon deals with Ebidramon, while Hawkmon armor digivolves to Huginnmon to face Coelamon. Taking advantage of the hustle and bustle, Jellymon sneaks aboard, but is caught off guard and knocked out by Penguinmon. Jō and Miyako's partners defeat Ebidramon and Coelamon, while Jellymon is rescued by Jō. Upon recovering, Jellymon confirms Miyako's suspicions and it and Penguinmon offer to accompany everyone to Dagonmon's Ice Fortress. Jellymon shows up with Desmomon at the entrance of the Ice Fortress, which resembles an immense cylindrical with a diameter of about 120 km and its height above sea level is almost 1 km. Desmomon wears fake Black devices and is presented by Jellymon to the guards, two Piranimon, as a new servant of Dagonmon; also, jokingly, it compliments the guards because up until the day before there were two Tobiumon. In reality, Jō, Miyako and Penguinmon are hidden inside Desmomon, who in this way manage to sneak into the fortress without arousing suspicion. Jellymon explains that the fortress is powered by four reactors scattered throughout the structure, each of which holds a Spirit, which has the task of supplying energy to the activities conducted on the adjacent floors and collectively allow the entire network of black obelisks to function. The entire structure is full of guards controlled by Black devices, but they can be avoided by passing through the ventilation shaft that vertically crosses the base and connects the reactor's rooms. Taking advantage of a shift change between the guards, Jō, Miyako and their Digimon manage to avoid the surveillance that stands between them and the reactor room. However, in front of the door they find a Yakiimon and a Potamon who attack them. Desmomon and Huginnmon quickly overcome their enemies and together with their partners, Jellymon and Penguinmon enter the room where the H Spirit of Ice is kept, which is stored in Jō’s D-Terminal, then the six jump into the ventilation shaft. As soon as they arrive in the second reactor room, the group is surprised by a Minotarumon, accompanied by a Frigimon and a MudFrigimon, which was about to carry out a routine check. Desmomon and Huginnmon are in the minority, but the H Spirit of Ice allows Penguinmon to digivolve to Kumamon, so the three Digimon are able to defeat their opponents. However, while Miyako stores the H Spirit of Water in her D-Terminal, Minotarumon manages to raise the alarm, so that when the group reaches the third reactor hall they find a welcoming committee. In fact, the six are attacked by a Shellmon and a MoriShellmon, while a MetalPiyomon and a Kokuwamon digevolve, respectively, to MailBirdramon and to BladeKuwagamon by activating a machine, which is connected to the B Spirit of Water in order to extract its power. Determined to intervene, Jellymon digivolves to Ranamon thanks to the H Spirit of Water and, destroying the machine, retrieves the B Spirit of Water, to then deliver it to Miyako who stores it in her D-Terminal. Defeated the enemies, the group throws themselves into the ventilation shaft one last time, reaching the room of the fourth reactor. While still falling, the six watch in the room below two Rookie Digimon, Gladimon and Thundermon, digivolving thanks to the machine connected to the B Spirit of Ice at the Champion level, respectively to Knightmon and to Mamemon. However, the group lands on the machine, causing its beam to deflect, which hits a stray Black Gear that lodges in the back of a second Gladimon, causing it to digivolve to SkullKnightmon. In the impact of the fall, the machine explodes, causing the digivolution of Mamemon to Giromon, of SkullKnightmon to DarkKnightmon and of Knightmon to ShineKnightmon.

We have no chances anymore
Dagonmon easily gets the better of Pegasmon and Nefertimon, but the shutting down of the Ice Fortress causes all remaining black obelisks to instantly collapse. Taken by surprise, Dagonmon stops and at that moment an hatch opens in the ground from which Baromon emerges and carries Takeru, Hikari, Patamon and Plotmon away into the depths of the Digital World. Meanwhile, inside the power plant Ballistamon is defeated by Kimeramon and degenerates to Tentomon as does Kenkimon, who degenerates to Armadillomon. At that point one of the Gotsumon, trying to protect the imprisoned Digimon, thanks to the H Spirit of Earth digivolves to Grumblemon. However, outside the industrial complex in which Koushiro and Iori are trapped, a FlameWizardmon materializes and casts a spell that teleports Koushiro, Iori, Tentomon, Armadillomon, Beetlemon and Grumblemon to who knows where. Instead, in the fourth reactor room of the Ice Fortress, a Sorcermon materializes and teleports Jō, Miyako, Gomamon, Hawkmon, Kumamon and Ranamon to an unknown location. Finally, a Wizardmon appears in the room where Sora, Mimi, Daisuke, Piyomon, Palmon, Veemon, Kazemon, Arbormon and Mercurymon are trapped, all of whom are also teleported to an unknown destination by magical Digimon. Baromon explains to Takeru and Hikari that it is still a living witness of the Ancient War. Takeru and Hikari surprise Baromon by claiming that they are already aware of the conflict, then Baronmon raises and offers them to hear what happened before.
