Fan:Digimon: Millenniummon Descends (2022 film)

Digimon: Millenniummon Descends is a fanon live-action film idea created by CAJH. It is the sequel to Digimon: Fight for Survival and Digimon: Dramon’s Roar, the fourth and the final installment of the Millenniummon Arc, and the seventh installment of the fanfictional multimedia franchise idea. The story of the film is inspired by several elements from 1999 Adventure and 2020 Adventure: continuities as well as few recurring elements from Digimon mythologies. The story of the film starts one year after the events of Fight for Survival but features a flashback sidestory between the main events and Fight for Survival.

The initial story idea of Digimon: Millenniummon Descends will be released to the Digimon Wiki on January 2023. The ”Digimon 2021 Fan Fiction Universe Story Idea Group” is also actively recruiting other people to suggest their own ideas or story changes for a potential full script.

 * The Junior Chosen Children, especially Will, questioning why the Chosen Children are even needed if there were ways of defeating the enemies without them, and because of the Sovereign Beasts’ civil war about whether the children are needed or not.
 * All thirteen Chosen Children learning to make their own choices, rather than being guided by anyone, and trying to reclaim the trust of the general public to regain what the light of hope needed to destroy Millenniummon.

Plot

 * The intro recounts all the events of Fight for Survival that led to the current moment. Right after Dyson, Ken, Tyler, Hikari, Will and Lopmon return from the Dramon Lands with Imperialdramon, Goddramon and Holydramon, and start fighting Millenniummon.


 * The major plot points of the First Act:
 * One year later, all the Chosen Children don’t remember anything from what happened while they were the Chosen Children. They only remember how a mysterious phenomenon had threatened the world one year ago. Especially the Senior Chosen Children have changed a lot: Taichi has become serious, Matt has become open and friendly, Sonya has become more feminine, Connor has become more proactive and social, Mimi has become more confident, and Joe has become resourceful and balanced. But the Junior Chosen Children feel that something is still wrong, since they are seeing mysterious nightmares. Due to this, they are all constantly meeting up with a therapist and life-coach named Julius Oatway.
 * An urban legend is told that mysterious lights and lights appear in certain parts of the city but suddenly disappear. The Junior Chosen Children keep investigating it because after everything the world has went through and convinced by their nightmares, they are ready to believe anything. They find three flaming creatures who look like they are trying to show something. Purple dimensional cracks opened by Millenniummon reappear around the world, along with several spirit-like creatures resembling MoonMillenniummon. The memories of all mankind are immediately restored. They remember the existence of the Digimon once again, and start panicking. They also start blaming the Chosen Children for these latest events.
 * When the law enforcement starts to chase the Chosen Children, the Juniors regroup with the Seniors, and the flaming creatures open three portals to forcefully send them back into the Digital World. The grown-up law enforcers and government officials are unable to follow them. The first portal takes Tyler, Hikari, Dyson and Ken. The second portal takes Taichi, Connor, Mimi and Milena. And the third portal takes Matt, Sonya, Joe and Evan.
 * When the Children arrive to the Digital World, they see an apocalyptic environment with similar dimensional cracks as in the real world. But the entire place looks like frozen in time and the dimensional cracks can take anyone to either different part of the Digital World or back to the real world. Things soon change when some of the environment starts to move again. The groups are jumping through cracks into different parts of the Digital World.
 * Agent Murdock and his task force are regrouped by their returned memories. Oatway offers to join the task force as its newest member, because he has spent years of trying to find a way to achieve a way for the grown-ups or non-Chosen children to enter that world. His career as a therapist for young people was part of a research to find out why the Chosen Children were so special. The other members of the task force allow him to join, but Murdock has an uneasy feeling about it.
 * Dyson, Ken, Tyler and Hikari arrive at a shrine, where a mysterious blue light also brings Will Dunham (whose own memories were recently restored) and Lopmon. They explain that the place is one of the shrines where the Digimon regularly visit to communicate with the Sovereign Beasts who have been the current rulers of the Digital World since Apocalymon’s defeat. A hologram of the Eastern Sovereign Beast, Qinglongmon, appears before the five children and into the locations of the other two groups. The Junior Chosen Children’s memories are restored, with Dyson, Ken, Tyler and Hikari recognizing Qinglongmon as the one who saved them from Nowell Sharpe and Piemon, and gave their partners the ability to mega evolve into Imperialdramon, Goddramon and Holydramon (without directly mentioning the events of Dramon’s Roar).
 * Qinglongmon shows visions and starts to explain what has happened. Ever since the Moon of the Digital World was destroyed as part of Millenniummon’s resurrection, an apocalypse started in the Digital World, and the dimensional cracks only made things worse. The battle between the Chosen Children and Millenniummon was interrupted because happened that forced the Digital World put into Sleep Mode (darkening and immobilizing it for the time being), with only the Sovereign Beasts being allowed to remain active.
 * But Millenniummon’s powers could not be contained in Sleep Mode for longer than one year. And since the time has nearly passed, the Digital World is slowly starting to become active again. Qinglongmon tells the Chosen Children find what they need to defeat Millenniummon and disappears.
 * After that, the evil spirit creatures (which Qinglongmon referred as Millenniummon’s Extensions) reappear in the locations of the Chosen Children and start transforming into other kinds of Digimon. Everything the Extension Digimon touch turns into crystal. The Senior Chosen Children who still do not remember anything, are confused, and do not know what to do. The Juniors encourage them to try to remember their past, thinking that it is what they needed to reclaim.
 * Although struggling at first, the Digivices reappear on their hands, and Agumon, Gabumon, Piyomon, Tentomon, Palmon and Gomamon appear before them. The six reappeared Partner Digimon evolve into Champion forms and then into Ultimate forms to fight the Extension Digimon. But the Partner Digimon are only able to maintain their Ultimate forms for a short while, due to the Senior Chosen Children not accustomed to their returned memories just yet.
 * Lopmon also evolves into Tueryemon and fights the Extension Digimon. But the shrine starts to collapse, and Will and Lopmon are separated from others while trying to escape. The same flaming creatures that brought the Chosen Children into the Digital World take Dyson, Ken, Tyler and Hikari to safety. But the children wonder why Veemon, Wormmon, Hawkmon, Armadimon, Patamon and Tailmon have not reappeared. And Connor is unable to locate or even contact Huckmon, Spadamon or any other ally Digimon.
 * Oatway introduces Murdock to the other child patients who express their desire to be just like the Chosen Children but better. Oatway and his assistant are trying to artificially gift them a potential to be a Chosen Child by examining Millenniummon’s energy and trying to develop a safe non-distorting way to change people’s potential and the Digital World. The children show signs of anger when Murdock questions if they are doing this on their own will or convinced by Oatway. They even consider other people ”trash”, just like the Digimon Emperor used to.


 * The major plot points of the Second Act:
 * Taichi’s group reaches a city under a dome filled with many Machine-type Digimon and replications of many familiar landmarks from the real world. The residents seem still immobilized but one Digimon, Andromon, is still walking. He is first assumed to be an enemy, because Connor analyzes a fragment of Millenniummon’s energy within him. Andromon admits that he was forced into the Disciples of Apocalymon against his will. Even his part of his own data was taken from him to construct Mugendramon.
 * Matt’s group finds its way to the Village of the Beginnings where Elecmon and Spadamon’s resistance group were immobilized due to the effects of the Sleep Mode started.
 * The weakened Qinglongmon is met by another Sovereign Beast: Zhuquemon. Zhuquemon is angry at Qinglongmon and Huckmon for bringing the Chosen Children back. Qinglongmon states that the Digital World needs the children, but Zhuquemon blames the children for failing to stop Millenniummon’s resurrection and for being a danger for the contingency plan to defeat Millenniummon without the children’s help is the only option. Zhuquemon is also revealed to have saved Will and Lopmon from the collapse of the shrine, so he could prevent them from the interfering.
 * Zhuquemon directly contacts the task force, using Huckmon’s old communication routes, declaring the Chosen Children as failures and revealing a contingency plan from the Kernel itself to defeat Millenniummon: the Reboot. The Reboot would return the Digital World and majority of its inhabitants back to the state where it was before Deathmon even created Millenniummon. It would also restore all the Digimon who died outside of the Digital World, including Leomon and Wizardmon. Murdock openly disagrees with this plan and tries to explain his suspicions about Oatway to the other member of the task force. But the task force believes that Murdock has become too attached to the Chosen Children and accepts the Kernel’s plan. Murdock runs away and becomes a fugitive in the process, while Qinglongmon frees Will and Lopmon.
 * Dyson, Ken, Tyler and Hikari find themselves from the Holy Ruins where Will and Lopmon are brought by Qinglongmon. They contacted by Connor who uses the main terminal of the Dome City activated by Andromon. Will angrily reveals the truth about the upcoming Reboot and claims that the Chosen Children were never needed to save the Digital World. Lopmon is also disappointed by the Kernel’s decision, but still refuses to believe that the children were unneeded, leading to an argument with Will. Tyler and Hikari are also conflicted because the Reboot could restore their deceased allies and allow them a happy life.
 * The flaming creatures (who are revealed to be called At, Rene and Pol) transform into an apparition of a knight-like Digimon with similar elements than Huckmon. He is revealed to be a Digimon named Jesmon. The Chosen Children experience a flashback:
 * Omegamon started to separate back into Agumon and Gabumon soon after Dyson, Ken, Tyler, Hikari, Will, Imperialdramon, Goddramon and Holydramon had returned to the Digital World with Qinglongmon’s help. Three Dragon Digimon had tried to fight against Millenniummon but were outmatched. Huckmon had suddenly appeared, and warp evolved into Jesmon who activated the Sleep Mode and sent the Chosen Children back to the real world where the mankind slowly started to lose its memory about the Digital World and the Chosen Children was forgotten, remembering only the desturction caused by the real world invasions.
 * Jesmon also convinced the Kernel to authorize the Sleep Mode plan before going through the Reboot plan. But he says that the amnesia was not his doing. Someone else used it to sabotage his plans. The Junior Chosen Children ask why the Reboot was not the first option rather than last one, Jesmon reveals that the Reboot would not also affect the real world in form of a temporary global blackout, which is why the Reboot is usually the last resort.
 * After the explanation, Jesmon also reveals that Imperialdramon, Goddramon, Holydramon and Millenniummon’s physical body are still immobilized in the space around the Digital World. He also reveals that he will die when the Sleep Mode ends but is willing to accept because he is the only Guardian Knight who survived the ancient war against Millenniummon and believes that he does not deserve to be a messenger anymore. He also says that he and Qinglongmon cannot help the children any further because of Zhuquemon and the Kernel. The children must now make their own choices if they want to find a way to defeat Millenniummon before the Reboot.
 * Will is uncertain because he is accustomed to act under guidance. He is also uncertain because he has not seen himself as a friend of the other Chosen Children, but rather a messenger who dragged other people into fighting against Millenniummon on behalf of the Sovereign Beasts and the Kernel, whom he is unable to fully trust anymore. Lopmon is the only one Will has considered as an actual friend.
 * The Extension Digimon attack again, but this time Senior Chosen Children rediscover what made their partners evolve to their Mega forms and succeed. Because Dyson’s, Ken’s, Tyler’s and Hikari’s partners are not there to protect them, Will is forced to protect his fellow Chosen Children by himself. His decision to take the destiny into his own hands, allows Tueryemon to ultimate evolve into Andiramon who defeats most of the enemies.
 * Andiramon also summons Hawkmon and Armadimon back to help the other two groups and forms a contact with Imperialdramon, Goddramon and Holydramon to allow the holographic images of Veemon, Wormmon, Patamon and Tailmon to appear. Elecmon, Spadamon and the resistance group are also able to move again and join the battle. But the children are unable to prevent one of the Extension Digimon from kidnapping Ken. Veemon, Wormmon, Patamon and Tailmon reveal that someone in the real world trying to prematurely free Millenniummon’s physical body from the Sleep Mode. The children are then contacted by Murdock who confirms their suspicions that the person is Oatway. But Murdock also ends up revealing his location to the task force, leading to his arrest.


 * The major plot points of the Third Act:
 * The children arrive at Oatway’s facility where Ken’s body and Digivice were analyzed to modify his other patients referred by Oatway as the ”True Chosen Children”. Oatway reveals that he is an old friend of all of the Junior Chosen Children’s parents and how he had been aware of the existence of the Digital World ever since he was a child. After finding out that his friends’ children were chosen, Oatway wanted to enter the Digital World too but was unable to enter any portals due to being an adult and without a Digivice. He was convinced by his ”inner voice” that he could not only save the Digital World by using Millenniummon’s energy through the children but also transform into a place that could also be accessed by people without a Digivice.
 * Ken is certain that this ”inner voice” is someone manipulating both Oatway and the ”Influenced Children”. The furious Oatway refuses to believe this, but then, the Partner Digimon assigned for those children were the Extension Digimon in disguise. The dimensional distortions also worsen and Millenniummon’s real body is able to move again in the space around the Digital World. Children around the world start seeing a broadcast that talks with a voice resembling that of Oatway and convincing all humans around the real world that there is no hope and that even the Chosen Children or the Reboot would be unable to save them. But Oatway himself has no idea what is going on and says he never wanted destruction. The voice soon changes into that of Oatway’s assistant who steps out and transforms into a being who is a fusion of Nowell Sharpe and Piemon, the former leaders of the Disciples of Apocalymon.
 * Nowell-Piemon removes the Influence from Oatway whom he no longer needs. Then, he restores the last missing memory of all mankind (the one about his own face), revealing himself to be responsible for the global amnesia. He reveals that his and Piemon’s own distortive powers protected them from the Sleep Mode of the Digital World but fused them together into one twisted human-Digimon hybrid. He then escapes with the Influenced Children to the Digital World.
 * The Chosen Children, accompanied by Andromon and Spadamon’s resistance group, follow their enemies to the space around the Digital World. Ken and Evan also take the weakened Oatway with them. Imperialdramon, Goddramon and Holydramon are still unable to move for some reason. But when Millenniummon is about to launch an attack that would kill the three Dragon Digimon, Jesmon appears between and sacrifices himself. Just before he dissipates, he expresses his faith that the children will manage to stop Millenniummon one last time. Nowell-Piemon laughs and mocks Jesmon for being in a hurry to die. That is when Imperialdramon, Goddramon and Holydramon start moving again.
 * Taichi and Matt try to ultimate fuse WarGreymon and MetalGarurumon into Omegamon once again but fail. They remember that it was the ”light of hope” sent by humans around the world who had faith in the Chosen Children that allowed Omegamon’s ultimate fusion in the first place. The Chosen Children’s failure to stop Millenniummon’s resurrection a year ago had made the light of hope disappear and Nowell-Piemon’s manipulations had prevented the humans from regaining it.
 * While the Partner Digimon remain in the space fighting Millenniummon, the children find a way to enter the manifestation of Millenniummon’s core, resembling a giant crystal chamber. Oatway confronts Nowell-Piemon, but instead of being angry at his assistant using him, he is more concerned about Nowell’s mental well-being and Nowell’s inability to believe in a bright future. But Nowell-Piemon mercilessly stabs Oatway with one of Trump Swords. The Chosen Children are so angry at Nowell, accusing him of being a miserable man who is making others miserable simply because his own life was miserable.
 * Then, Piemon’s voice alone starts speaking from Nowell-Piemon’s mouth and reveals that this is why he chose Nowell is his partner. Piemon then transforms his and Nowell’s fused body into a rotten figure with a metallic mask. He reveals that he is, in fact, Apocalymon himself, and how the real Piemon died fighting against the previous Chosen Children. The remainder of Apocalymon took over his lifeless body.
 * Apocalymon himself was born as a composition of Digimon who did not survive when the Digital World changed and evolved after Millenniummon’s original defeat. Before their deaths, the spirits of the dying Digimon had cursed the Digital World, and so the Core of All Digital Darkness turned their data into a being whose very desire for revenge for their unfair past life would be a catalyst of the end of the Digital World. Apocalymon first tried to achieve this by using its own distorting and evolution reversal powers, but after he failed and barely survived inside Piemon, the Core of All Digital Darkness partnered him with Nowell and gave them means of resurrecting all the previous Dark Digimon, starting from Millenniummon.
 * Apocalymon encourages Millenniummon how to destroy the worlds, but Millenniummon suddenly attacks him with the black lightnings and starts speaking with the same voice Ken heard as the Digimon Emperor. He tells Apocalymon not to give him orders and then starts talking directly to the Chosen Children, revealing that it was Deathmon’s plan all along for his creations to overpower him and threaten the interdimensional stability.
 * Millenniummon is even not interested of the goals of the Core of All Digital Darkness, despite doing exactly what the Core wanted and letting VenomVamdemon to be destroyed by the Chosen Children five years ago. Despite his mind slowly evolving to become intelligence after his first defeat in the ancient war, Millenniummon chose to remain as the very thing he was created to be: the bringer of chaos and destruction. And he made the choice based on what he was created from: a chaotic and violent mix of data from other Digimon species.
 * Apocalymon tries to talk back at Millenniummon who just tells them to destroy the Chosen Children. Apocalymon is not as powerful as it once was but manages drain the dark energy from the Influenced Children to conjure weapons that are based on DanDevimon’s, VenomVamdemon’s, MetalSeadramon’s and Mugendramon’s attacks and uses them against the Chosen Children. Hououmon, HerakleKabuterimon, Rosemon, Vikemon, Sigurdmon, Shakoukimon and Andiramon appear into the chamber to fight Apocalymon, while WarGreymon, MetalGarurumon, Imperialdramon, Goddramon and Holydramon keep fighting against Millenniummon. The two powerful Dark Digimon manage to even force the Partner Digimon back into their Rookie forms.
 * The wounded Oatway is conflicted about finally being in the Digital World, blaming himself for falling into Nowell-Piemon’s trap. But Ken opens about his past feelings about Samuel’s death and his time as the Digimon Emperor and reveals how Oatway himself had helped him to finally forgive himself. He and the other Chosen Children agreee that while Oatway was a victim of manipulation, he helped them find out what they want to do after graduating from high school and becoming adults. The Chosen Children also manage to convince the Influenced Children to snap out of their despair and take control of their own lives.
 * Millenniummon tries to create new Extension Digimon to attack the formerly Influenced Children, but the children gain real Digivices and real Partner Digimon to defend them. The Digivices are like that of Ryo Akiyama’s at the end of Dramon’s Roar and they have no Crests of their own. People around the world are seeing footage of this and hearing the Chosen Children’s speeches from their computers and televisions, restoring the light of hope, which, together with the power of the Crests, warp evolves all the Partner Digimon back into their Ultimate and Mega forms.
 * WarGreymon and MetalGarurumon also regain the ability fuse into Omegamon once again while Imperialdramon gains an ability to switch into the Knight Mode. Andiramon recognizes Imperialdramon Knight Mode as the second Guardian Knight who helped Omegamon to defeat Millenniummon in the ancient war. Millenniummon also tries to use the distortions to transport every attacking opponent into a location where either he or Apocalymon could launch a counterattack, but the Partner Digimon manage to fight back despite it. Qinglongmon joins the battle and even Zhuquemon is moved enough to join the battle. The two Sovereign Beasts hold Millenniummon and give Goddramon, Holydramon, Imperialdramon and Omegamon a chance to destroy him. Meanwhile, the other Partner Digimon manage to destroy Apocalymon’s tentacles. And the light of the Digivices forcefully separates Nowell from Apocalymon’s body.
 * However, before the Crystal Chamber Core of Millenniummon can be destroyed, the sad and hateful spirits that formed Apocalymon’s collective mind, however, are angry at their defeat. They burst out of Nowell’s body and self-destructively launch themselves the Chamber. Its destruction resurrects Millenniummon in a more powerful form: ZedMillenniummon, a large Digimon which looks like the spirits of Mugendramon and Chimairamon bonded together. Qinglongmon and Zhuquemon reveal that the reason why the Kernel originally wanted to proceed with the Reboot was to defeat Millenniummon before it could ZedMillenniummon, which would be powerful enough to even stop the Reboot from occuring.
 * ZedMillenniummon absorbs Apocalymon’s spirits, and its mere presence is a distortion which allows its attacks to simutaneously cause damage to the real world and the Digital World, destroying a couple of cities and killing a significant number of humans and Digimon. The Chosen Children and all the Digimon with even small amount of light inside, also refuse to let ZedMillenniummon win, and their inner light of hope allows Goddramon and Holydramon to transform themselves and the other nine Chosen Partner Digimon to transform Omegamon and Imperialdramon into two even more powerful Digimon: Omegamon Heavenly Mode and Imperialdramon Heavenly Mode.
 * The two powerful Digimon block every single attack until they are ready to force ZedMillenniummon to separate into two separate beings by using Fearsome Blades and Supreme Sword respectively. Omegamon Heavenly Mode’s Graceful Cannons obliterates Mugendramon’s spirit half by using both and Imperialdramon Heavenly Mode’s Bright Death obliterates Chimairamon’s spirit half. The countdown to Reboot also pauses, since the children succeeded in destroying Millenniummon.
 * The Core of All Digital Darkness itself teleports before the Chosen Children, Omegamon and Imperialdramon, opening its large yellow eye, and forcibly teleporting its enemies back to the real world. When the children find themselves in the real world, the yellow eye of the Core appears in a black background in Connor’s tablet computer. DigiLetters also appears on the screen with a strange sound effect (the voice of the Core) being heard of the background. The letters read as ”Apocalymon...ZedMillenniummon...Those deaths shall become the catalyst! To open the path to bring forth the true Multiversal Catastrophe! We shall meet again, Chosen Children, on the day when everything is supposed to end!” After that, the Core teleports somewhere else and Connor’s tablet computer returns to its normal state.
 * Nowell is exhausted but still refuses to let go of his negative feelings or aim for a bright future, promising to keep dedicating his own life to destroy the Chosen Children, their partners, and the rest of the mankind or the Digimon. Oatway is dying and offers to become a spirit who would replace Jesmon and the new messenger. He also advices the Sovereign Beasts, including Xuanwumon and Baihumon, and the Kernel not to kill Nowell but give him a punishment that would also allow Nowell to redeem himself one day.
 * Oatway creates a paradise-looking pocket dimension and transforms Nowell into an intangible being who cannot touch anything or leave. Nowell would remain imprisoned, unable to either enjoy or damage anything, and even unable to age. Only if Nowell would ever genuinely feel genuine remorse for his actions, he would regain his freedom and mortal life.
 * The Kernel uses the modified and partial version of the Reboot’s restoration powers to restore the Moon of the Digital World and allow the data of the deceased Digimon to be returned to the Digital World to be reformatted into Digi-Egg. Spadamon begins to raise the reincarnation of Leomon (in his Baby form) while Wizardmon’s and Jesmon’s Digi-Eggs remain with Elecmon. The Kernel and the Sovereign Beasts announced that they would soon enter a deep sleep to regain some of their lost powers, but not before declaring the formerly Influenced Children as the first ”Tamers”.
 * Everyone also talks about how the Core of All Digital Darkness can easily teleport itself to any place, so straight attack would be impossible. The only choice is to wait until the Core would finally make its move to start the true Multiversal Catastrophe it spoke about. While the Chosen Children (now referring themselves as the Chosen Ones, due to them reaching adulthood soon) are certain they will never be separated from their partners again, Zhuquemon and Qinglongmon (before entering their sleep) know something about the Chosen Children’s fate that they decide not to reveal yet.
 * Until time for the next battle comes, the Chosen Children decide to help all humans and Digimon whose lives were affected by the destruction caused by Millenniummon and try to better the relations between the two worlds. Murdock resolves to help the children as an independent consultant. He also reveals that he has managed to find the previous Chosen Children who defeated Apocalymon’s original form.


 * The mid-credit scene:
 * Inside the black orb, a tentacled being is holding a crystal that constantly changes its form and color very violently. The being speaks through its sound effects, with both the DigiLetters and Latin alphabet translating it is: ”Let it be heard again! The true voice of darkness! To call upon the arrival of the Multiversal Catastrophe! My arrival!” That is when the being opens its yellow eye again.

Development
When CAJH was trying to figure out how deal with Millenniummon’s resurrection in Fight for Survival in the previous films, he initially considered Ultimate Holy Battle as the title because of the 50th episode of Digimon Adventure: being titled ”The End, the Ultimate Holy Battle” and featuring a final battle against Millenniummon too. But after Ultimate Holy Battle was moved to be the title of another installment, the new title for the sixth main installment was changed into Millenniummon Descends, which is inspired by the title of the 49th episode of Digimon Adventure: (”The God of Evil Descends, Millenniumon”).

 * There were initially conflicts during the drafting process about whether to restore Leomon and Wizardmon back to life. CAJH did agree to restore them in a way that they would not have the memories of their past lives, since they were no Partner Digimon.
