Fan:Digimon: Fight for Survival (2022 film)

Digimon: War for Evolution is a fanon live-action film idea created by CAJH. It is the sequel to Digimon: World Disaster and the fifth installment of the fanfictional film series 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 eighteen months after the events of World Disaster.

The main story points and ideas of Digimon: War for Evolution were released to the Digimon Wiki on June 19, 2021. The ”Digimon 2021 Fan Fiction Film Series Story Idea Group” is also actively recruiting other people to suggest their own ideas or story changes for a potential full script.

Planned intro
The intro starts by repeating the mid-credit scene of World Disaster. The malevolent young man with a pale face witnesses a two-headed spirit-like being inside Chimairamon’s crystal. Then, he touches the large black cube with orange sparks. He and the cube are both resonating with each other. The symbol of the ”Dark Digital Cosmos” activates around the Digital World in five different places, including the malevolent young man’s location.

Planned story elements

 * Eighteen months has passed from the battle against DanDevimon, VenomVamdemon and Nidhoggmon. It is December in the real world. The world is still debating about the Digimon, but no new attack has been seen in the real world yet. The identities of the thirteen Chosen Ones are now a public knowledge.
 * Meanwhile, in the Digital World, everything has turned wilder and more brutal. Several Digimon are fighting each other for survival. The WWW Continent has already been in such state for many years.
 * Connor finds out that the network is filled with new green Digi-Eggs which hatch into several new Algomon. But this time, the Algomon are also joined by new kinds of Virus Digimon, like Kuramon and Zurumon hatching from grey and yellow Digi-Eggs.
 * Agent Murdock informs the Chosen Ones that there has been a break-in and Chimairamon’s crystal has been stolen.
 * The Chosen Ones realize that instead of being healed, the damages of the Digital World are getting even worse for some reason. One refugee camp is established by Spadamon who is revealed to have been Leomon’s apprentice before her mentor’s death.
 * Spadamon tells the Chosen Ones about the Cult of the Dark Digital Cosmos, a group of Digimon who desire power from the black lightnings generated by the actions of Algomon, Kuramon and Zurumon in the Network. The fight for survival was a natural reaction to damages caused by Nidhoggmon, but now the situation is even more intensified by the black lightning and the appearance of the Cult.
 * Several Ebidramon are fighting against several Seadramon. Two of them kill two Seadramon and eat their data to evolve to Anomalocarimon and Gusokumon. WickedSeadramon, which bears the symbol of the Dark Digital Cosmos, eats the other Ebidramon and is then struck by a black lightning, ultimate evolving it to MetalSeadramon. MetalSeadramon lets Anomalocarimon and Gusokumon live, and the symbol of the Dark Digital Cosmos appears in their bodies.
 * Megadramon and Gigadramon, who are members of the Cult of the Dark Digital Cosmos, have helped the High Priest and his Partner Digimon imprison several Machine Digimon. But even small part of his data is enough to complete the construction of Mugendramon.
 * MetalSeadramon and Mugendramon both are given a large distortion which sends them to Spadamon’s refugee camp. The two attacks not only the refugees but the Chosen Ones too. MetalSeadramon is too powerful for Adult Level forms and Mugendramon who easily defeats all Perfect Level forms of the Partner Digimon. Mugendramon even causes Garudamon to suffer a dangerous head trauma.
 * The High Priest of the Cult of the Dark Digital Cosmos introduces himself as Nowell Sharpe and his Partner Digimon is Dracmon. Hikari senses that Nowell is not manipulated like Ken and Oatway were. Nowell does not even have a Digivice, so instead he uses his inner anger and desire for destruction to make Dracmon warp evolve to Piemon who single-handedly defeats both WarGreymon and MetalGarurumon.
 * Nowell and Piemon also have one of crystal fragments and they use it a create a large black sphere, imprisoning Dyson, Veemon, Ken, Wormmon, Will and Lopmon inside. Every other Chosen One manages to escape to the real world.
 * Few days later Taichi’s, Matt’s and Sonya’s class gets a new transfer student who is also Taichi’s new neighbor: Meiko Mochizuki who just moved from Japan with her family due to her father’s job. She is revealed to have a Digimon named Meicoomon.
 * Piyomon wakes up but suffers from amnesia, acting hostile towards the Chosen Ones, and especially Sonya, who becomes deeply saddened. Sonya is unable to be happy even about her father Mikhail, who has spent much of time overseas due to his job these last years, has started to spend more time on home lately.
 * Joe was unwilling to fight anymore because he has recently failed some of his studies lately and he is worried that his duties as one of the Chosen Ones are a hindrance. Gomamon is angry at Joe because he thought that Joe had already given up taking studies too seriously. But Joe defends himself by stating that this time he really failed and disappointed his parents and himself.
 * Murdock introduces the Chosen Ones to Meiko’s father, Professor Mochizuki, a leader of an international task force created to explore the Digimon phenomenon. Mochizuki fully supports the Chosen Ones due to his daughter having a Partner Digimon as well. Mikhail Tarkovsky is also a member of the task force and so is one of Mochizuki’s subordinates, Daigo Nishijima, who has been monitoring the Chosen Ones undercover in their high school as ”Mr. Nojima”.
 * Huckmon and the Spirit of Julius Oatway appear and introduce the Chosen Ones to Homeostasis who takes over Hikari’s body and reveals the hidden details of three great wars in the Digital World:
 * The Digital World was created by the Quantum Sea, the primordial world through the computer network of the human world and its rulers are several unmaterialized programs referred as the Servers and the Main Server called Yggdrasill. They wielded a divine power called Kernel which resided in the core of the Digital World. Homeostasis is also one of the Servers. And time of the Digital World flowed much faster in the past. Mere minutes in the real world were like several years in the Digital World.
 * In the First War, the Seven Holy Archangels (Seraphimon, Ophanimon, Cherubimon, Rasielmon, Baldrmon, SlashAngemon and ClavisAngemon) destroyed the Seven Ancient Demon Kings (Lucemon, Leviamon, Cacodaemomon, Belphemon, Barbamon, Beelzemon and Lilithmon) and sealed the essence of the Deadly Sins away in order to prevent them from ever being reborn.
 * After that, the Regent Demon Lord Deathmon had appeared and waited until the Holy Powers would grow old. After many long years, the power of the Holy Archangels weakened, and the rumors of an apocalypse and self-destructing paranoia among many Digimon allowed Deathmon to turn into the destructive Black Deathmon and create Millenniummon to help him destroy the Digital World.
 * In the Second War, Millenniummon turned against Deathmon and destroyed him. The Holy Archangels, the Guardian Knights, and five Northern Guardians fought against Millenniummon. Millenniummon destroyed almost every one of its opponents, but the Guardian Knight Leader Omegamon, the four remaining Northern Guardians (Hououmon, HeracleKabuterimon, Rosemon, Vikemon), and three remaining Holy Archangels (Seraphimon, Ophanimon and Cherubimon) were able to destroy Millenniummon by sacrificing themselves and becoming Digi-Eggs. Jesmon, the Final Guardian Knight avoided the conflict out of orders given by the Servers and was degenerated back to its Child Level form: Huckmon. Leomon and Wizardmon are revealed to be reincarnations of the fifth Northern Guardian SaberLeomon and the Guardian Knight member Mystimon respectively.
 * Millenniummon’s actions, however, had made the time flow slower in the Digital World. It changed even more after a new form of darkness appeared to cause first distortions between the Digital World and the real world.
 * Five human children were discovered during this phenomenon, and they were chosen to enter the Digital World and help raise four Digimon who would become the new guardians of the balance. These five Digimon participated in the Third War, with four of them becoming the Sovereign Beasts while the fifth one was forced to sacrifice itself to destroy the source of the third darkness: Apocalymon.
 * Despite Apocalymon’s destruction, the flow of time in the Digital World has become even slower. It is now as slow as in the real world.
 * Taichi and others form the second wave of the Chosen Ones destined to wield the power of the Crests, the power of strong personalities and the power to save the Digital World from the Fourth War. The Fourth War is prophesied to be the most threatening of them all. Agumon, Gabumon, Patamon, Tailmon and Lopmon are already known to be reincarnations of WarGreymon, MetalGarurumon, Seraphimon, Ophanimon and Cherubimon. Piyomon, Tentomon, Palmon and Gomamon are reincarnations of Hououmon, HeracleKabuterimon, Rosemon and Vikemon. Hawkmon, Armadimon and Meicoomon are reincarnations of Baldrmon, SlashAngemon and Rasielmon. But the reincarnation of ClavisAngemon was still missing and stopping the Fourth War requires the power of all fifteen Crests.
 * Millenniummon’s soul, also known as MoonMillenniummon, survived inside the Millennial Crystal. And the dark feelings which created Apocalymon’s original body remained inside the Apocalyptic Cube. Small fragments of both the Crystal and the Cube were used by Devimon, Vamdemon and Eyesmon for evolution and to survive without a body. They were also used to manipulate Ken and Oatway. Ken had also used the Millennial Crystal to create the Chimairamon, which unknown to him was the first part of Millenniummon’s attempted resurrection plan. Devimon and Vamdemon desired only power and control over the worlds, but the Dark Digital Cosmos is planning to wipe all worlds out from existence completely.
 * The Chosen Ones realize that the Cult of the Dark Digital Cosmos is planning to empower the Crystal and the Cube to recreate both Millenniummon and Apocalymon to bring even greater darkness than during the Second and Third Wars.
 * Homeostasis considers the potential instability and chaos of both extremely powerful evil Digimon so dangerous that wants the Chosen Ones to fully prevent the two from ever returning.
 * Connor realizes that most of the ”empowering” of the Crystal and the Cube comes from the black lightnings, generated by the Kuramon, Algomon and Zurumon in the Network. They start causing new disturbances, generating new wild discussions in online about these situations, to create even more black lightnings.
 * The Millennial Crystal has been left under the care of several Vademon who are also members of the Cult of the Dark Digital Cosmos and currently hiding in the Moon of the Digital World. Nowell and Piemon keep the Apocalyptic Cube for their own purposes and send their own personal recruits Mephistomon, LadyDevimon and MarineDevimon to prepare to start chaos is the real world.
 * Connor spends hours without any sleep because he wants to track the Millennial Crystal’s location and what happened to Dyson, Ken and Will. But the black lightnings are striking into random places and random Digimon, so there is no certain point on which the lightnings would focus more than anywhere else. Digivice signals indicate Dyson is still alive, but Connor cannot figure out the exact location.
 * Dyson, Ken, Will, Veemon, Wormmon and Lopmon awaken inside the black sphere, which is much larger inside, and has a labyrinth-like structure.
 * The Chosen Ones occasionally try to destroy the Kuramon, Algomon, and Zurumon, but they multiply fast and even evolve. One Kuramon evolves all the way to Infermon, many Algomon evolve to all the way to Perfect Level Digimon, and some of the Zurumon warp evolve to Raremon. Every following day, the new larger waves of the Virus Digimon appear after each of the previous ones is defeated.
 * Taichi, Sonya, Mimi, Tyler, Hikari, Milena and Jonny decide to spend time with Meiko and Meicoomon, to make them feel welcomed to the Chosen Ones. Meiko does not know or even like anything about fighting or evolving. has suddenly disappeared. However, Meicoomon suddenly senses something and runs outside, and Parrotmon enters the real world.
 * Parrotmon starts to chase Meicoomon, who becomes afraid to even run away. When watching Parrotmon, Taichi and Hikari start to remember something: they have seen a Parrotmon once before in the real world.
 * LadyDevimon and MarineDevimon appear from the distortion as well. Angewomon takes the confrontation of LadyDevimon very personally but she interrupts the fight because Parrotmon is getting away to cause more destruction.
 * Mimi and Lillymon, who are worried about the people in online discussions criticizing the Chosen Ones and the Digimon, appear to fight Parrotmon but accidentally end up causing destruction and harming innocent people. Other Chosen Ones appear to help wounded people and coordinate the fight in a way that makes Parrotmon retreat.
 * Connor is angry at Mimi for acting without a proper plan, and because another battle had caused serious online discussion and attracted the attention of the Virus Digimon to generate even more black lightnings, which would accelerate Millenniummon’s resurrection. Meicoomon is still afraid, but Meiko’s presence makes her calm down.
 * In the Digital World, Nowell and Piemon torture Parrotmon as a punishment for his failure. Parrotmon asks for evolution but is refused to have one. He then insults Nowell for being a High Priest despite being a human, but the Vademon, who claim Nowell being ”chosen by both Millenniummon and Apocalymon”, start to participate in the torture of Parrotmon with their ray guns.
 * Mimi becomes even more upset when her classmates refuse her questionable ideas for a Christmas party.
 * Murdock notifies Professor Mochizuki and Nishijima that both the Chosen One and the task force are going to be under investigation due to the circumstances regarding Parrotmon’s attack. Oatway’spirit and Huckmon also arrive to notify that Homeostasis is not happy with the Chosen Ones either, warning that Homeostasis might consider dealing with the Cult without the Chosen Ones. Oatway’s spirit and Nishijima are worried, and Huckmon admits he is worried about Homeostasis' judgement, but refuses to ever turn against the Servers.
 * Taichi remembers how he and Hikari had seen a distorted holographic-looking Parrotmon to cause destruction when he was only 8 years old. Then, orange light had appeared to scan Taichi and pink light to scan Hikari. But after that Parrotmon had disappeared.
 * Matt and Tyler also remember seeing another Parrotmon and being scanned by blue and yellow lights. They had tried to tell their parents who had not believed them. The original nine Chosen Ones were only ones who had seen Parrotmon while witnessing the destruction. The past lights corresponded with their Crests’ colors, making everyone realize that this event was when they were ”chosen”.
 * Connor tries to contact Murdock about the past event, hoping to find out how the unlock the Ultimate Test for the other Chosen Ones, knowing that WarGreymon and MetalGarurumon will not be enough to defeat the Cult and the Virus Digimon.
 * Inside the black sphere, Lopmon senses something calling her, trying to guide Will and the others through to find out who is the one calling them.
 * Meiko starts to slowly befriend with Sonya and Mimi who are still upset of their own respective problems. Tyler, Hikari, Milena and Jonny start to spend more time her as well, due to Meicoomon being a Holy Digimon, just like their partners.
 * On the day Mimi’s class is going to hold its Christmas party, officials start interrogating the Chosen Ones for the investigation. The interrogations are interrupted when Meicoomon goes missing again.
 * Meicoomon is being held captive by LadyDevimon who has appeared into the real world again. Meanwhile, MarineDevimon starts to attack New York to create new chaos to the real world to intensify the black lightnings of the Digital World. Milena and Hikari remain to fight LadyDevimon, while Tyler and Jonny go after MarineDevimon.
 * Milena comes to hate LadyDevimon and wants to rise against the cruel female Digimon along with Hikari, making Aquilamon super evolve to Sigurdmon. Angewomon and Sigurdmon manage to destroy LadyDevimon.
 * MarineDevimon threatens the innocent people inside the hospital building, Jonny refuses to let injustice happen and his will to save lives makes Ankylomon super evolve to Shakoukimon. HolyAngemon and Shakoukimon manage to destroy MarineDevimon.
 * Despite LadyDevimon’s and MarineDevimon’s deaths, Meicoomon becomes so afraid that something triggers inside her. She becomes violent, revealing herself to be the one to open distortions for the members of the Dark Digital Cosmos to appear from.
 * Piemon manages to contain Meicoomon and reveals that long before Meicoomon’s Digi-Egg hatched, he had used a fragment of the Apocalyptic Cube to infect it. But instead of fully corrupting Meicoomon, she was born with two separate personalities: the original benevolent one and the malevolent destructive one. Meiko had been aware of this all along, because whenever Meicoomon was upset or anything, her darker personality had come out and started to rampage. Piemon then takes Tyler, Hikari, Milena, Jonny, Meiko, and their Partner Digimon through a distortion to the Moon of the Digital World where Nowell is waiting for them.
 * Nowell reveals how he had been abused by most of the people he knew while his only friends either abandoned him or died. He also saw so many bad things happen in the world that all positive things in the world felt like living in self-delusion. One day, he found out about the Millennial Crystal, stole it, and ended up in the Digital World where he met Dracmon. The Crystal had bonded him with Dracmon to allow him to use his exceptionally strong negative feelings as a method to warp evolve Dracmon to Piemon.
 * Dracmon himself was a creation of the original Apocalymon and he had been won the Third War. After Devimon’s, Vamdemon’s, Nidhoggmon’s actions had driven both worlds into more unstable state, Dracmon and Nowell had started the Cult of the Dark Digital Cosmos with the help of the Vademon who simply desired ”cosmic emptiness” over ”earthly life”. Nowell himself wanted the end of both worlds to happen because he wanted both revenge by first killing every other human and Digimon, and then, salvation by killing himself as the last human of Earth.
 * The ultimate plan was to use Meicoomon, due to her being one of the reincarnations of the Holy Archangels, as key to create ”the new Apocalymon” and also as the finalizer of the creation of the new Millenniummon. The black lightnings and the Virus Digimon were just serving not only as a slow-paced backup plan but also to act a preluding chaos to both worlds. Piemon split the Apocalyptic Cube into two pieces. The first half is forcibly fused with Meicoomon and Piemon himself fuses with the other half.
 * HolyAngemon and Angewomon are too exhausted to stop Meicoomon who super evolves to Meicrackmon Vicious Mode and forces the two Holy Digimon to degenerate. Nowell and Piemon laugh like maniacs, send Tyler, Patamon, Hikari and Tailmon into same labyrinth inside the black sphere where Dyson, Veemon, Ken and Wormmon are. Dyson is about to touch a blue glowing small orb, which Lopmon has sensed calling them. But then Piemon shatters the sphere. Dyson, Ken, Will, Tyler and Hikari are nowhere to be found. Milena and Jonny are horrified ang angrily attack but Nowell and Piemon just retreat into a distortion.
 * Unaware of what happened to Tyler and Hikari, Taichi and Matt decide to enter the Network to fight the Algomon, Kuramon and Zurumon swarms again. But before Mimi, Connor and Sonya can follow them, MetalSeadramon, Anomalocarimon, Gusokumon, Parrotmon, Mugendramon, Megadramon, Gigadramon and the Vademon appear in the real world.
 * Connor tells to run because they cannot defeat their powerful opponents, unless they learn how to access their own Ultimate Test and unlock their partners’ abilities to ultimate evolve. But he still does not know how to do it.
 * Taichi and Matt find out that the leading Infermon had evolved into Diablomon, the leading Algomon into Ultimate Level Algomon, and the leading Raremon into RareRaremon. Diablomon, and the Ultimate Algomon were powerful while RareRaremon was only light fire by the attacks, making the latter even more destructive.
 * Mimi calls Joe and tells him to come, because Gomamon needs him more than his studies. Joe refuses by saying that trying to become doctor was his own decision, not his father’s. Mimi shouts out angrily that it does not matter if life does not go as expected. She angrily tells Joe just to be there for Gomamon and his other friends, to ”be reliable friend and partner”.
 * Mimi then apologizes because she has not been good friend for others either due to not listening to them. Joe admits that he really wants to continue being a Chosen Ones but was afraid of its costs. Mimi admits being afraid of listening others because she did not want to compromise. Then, the portals suddenly open and take them to their Ultimate Tests.
 * In their respective Ultimate Tests, Mimi and Joe are being accused of not listening others properly and not taking others’ feelings into account. They are accused of being ”selfish cowards”. Mimi and Joe admit their own cowardice but feels that it is better than pretending. They also admit that at least trying despite failing to keep promise is better than purposely breaking it.
 * Lillymon then ultimate evolves to Rosemon who challenges MetalSeadramon and forced it to retreat from the other enemy Digimon.
 * Mugendramon tries to attack Piyomon, but Sonya comes between, refusing to let Mugendramon hurt Piyomon ever again. Sonya is hurt and seeing this makes Piyomon trust her again. Piyomon becomes able to evolve to Birdramon again and then into Garudamon.
 * Joe and Zudomon finally arrive to help and Joe even shows how he has learned to make Zudomon ultimate evolve to Vikemon.
 * Mimi and Joe explain how the Ultimate Test was available to them all along, without the need of the Holy Digimon to unlock it. Sonya decides to take her own. Sonya’s Ultimate Test is being pulled into an illusion where people are accusing her not learning how to earn others’ love despite learning how to respond to other people’s love. They call her for having an ”obsession” rather feeling any real love.
 * Sonya admits she cannot force people to like her and that she would leave Piyomon one if the latter were to ever want that, even though it would hurt. But she says that she should at least try to win the trust of someone she deeply cares about before giving up and that her love towards Piyomon is not a lie. After coming out of the Ultimate Test, she activates the full potential of the Crest of Love, which ultimate evolves Garudamon into Hououmon. The power of the Crest also restores Hououmon’s full memory.
 * Parrotmon and the Vademon are in disadvantage so the Vademon leader prays for the Millennial Crystal to give them what ”they need”. This starts a black lightning which ultimate evolves the Vademon leader into Ebemon and Parrotmon into Crossmon.
 * Connor is still upset because he feels like everyone else is solving problems without him. He feels ashamed of not realizing that the Ultimate Test was available to them all along. He does not think himself worthy of taking the Test, but AtlasKabuterimon encourages him to try it.
 * Connor’s Ultimate Test is being pulled into an illusion where people are accusing him not knowing answer to every solution and even claiming that it will be Connor’s fault if Millenniummon’s resurrection is successful. Connor realizes that not every answer has come out immediately and that while not being able to prevent something from happening, he might be able to at least cancel or heal some of the bad effects. He accepts how knowledge can always be repurposed when not being useful to solve the initial problems. After coming out of the Ultimate Test, Connor activates the full potential of the Crest of Knowledge, which ultimate evolves AtlasKabuterimon into HeracleKabuterimon.
 * Rosemon manages to destroy Crossmon, Vikemon manages to destroy MetalSeadramon, Hououmon manages to destroy Mugendramon, to avenge Piyomon’s earlier amnesia. Ebemon tries to deny the meaning of knowledge and preach for the cosmic emptiness, but Connor denies Ebemon’s word and HeracleKabuterimon manages to destroy Ebemon.
 * The remaining enemies retreat to a distortion. Sonya, Connor, Mimi, and Joe follow them and reach the Moon of the Digital World. There they meet with Milena, Jonny and Meiko who tell them what happened to Dyson, Ken, Will, Tyler and Hikari. Taichi and Matt hear about this, and their fighting spirit is crushed, giving Diablomon and the other Virus Digimon a chance to overpower WarGreymon and MetalGreymon.
 * Taichi’s and Matt’s fighting spirit is crushed even further after their Partner Digimon are knocked out. Nowell and Piemon reappear from the distortion to taunt them from their loss. Every Tamer watching from their own computers and smartphones around the world have faith that the lost Chosen Ones might still be alive and that Taichi and Matt can win. They also rediscover their courage and faith, and this time collective energy of all the Chosen One and Tamers makes WarGreymon and MetalGarurumon finally achieve the real ”ultimate fusion” of Omegamon.
 * Omegamon to destroys the Ultimate Algomon, most of the Algomon, Kuramon and Zurumon, and freezes RareRaremon before shattering its body. The remaining Virus Digimon ”ultimate fuse” with the wounded Diablomon to become Armageddomon who keeps producing even more Kuramon. Hououmon, HeracleKabuterimon, Rosemon and Vikemon come to help Omegamon while Sigurdmon and Shakoukimon face Mephistomon and Meicrackmon.
 * Nowell refuses to let other people’s hope and faith convince him from letting go his evil desire for destruction. He is stubborn and furious, so he tries to use his hate and anger to make Piemon even more powerful. After a lengthy battle, the flaming RareRaremon is frozen and then shattered. Mephistomon and Armageddomon are destroyed by regular attacks while Piemon is only forced to degenerate back into Dracmon.
 * Meiko tries to talk to Meicrackmon and Meicoomon’s good side is trying to take control. Because of the strong power of the Apocalyptic Cube, good Meicoomon only splits into a separate body rather than eliminate the evil one. But suddenly purple glowing raven-like beings appear and allow Meicrackmon’s own body to become stable without good Meicoomon. Huckmon is shocked and in disbelief, because he recognizes the ”Ravens”.
 * Meicrackmon then ultimate evolves to Raguelmon who transforms the remains of Armageddomon, MetalSeadramon, Mugendramon and Ebemon into a powerful black lightning which strikes into the Millennial Crystal. The crystal shatters and unleashes a partially deformed Chimairamon who forcefully pulls the data of living Kuramon and every living member of the Cult (except Nowell and Dracmon) and destroys them, with only the surviving Vademon willingly accepting it. Chimairamon then ultimate evolves to Millenniummon.
 * Homeostasis’ voice is heard somewhere in the Digital World is disappointed and declared the Chosen Ones’ mission as failure. After that, somewhere else, an entity surrounded by the purple glowing ravens speaks in computer language (subtitled to English): ”Purge the Digital World. Purge the Human World. Purge everything.”
 * Millenniummon and Raguelmon are so powerful that they force every Partner Digimon, except Omegamon, to degenerate to their Child Level forms. Raguelmon starts to slowly dissolve the Moon while Millenniummon uses its Time Unlimited technique to trap most of the Chosen Ones, except Taichi, Matt and Omegamon, into an unspecified dark dimension.
 * Taichi, Matt and Omegamon see a portal from which Imperialdramon Dragon Mode, Andiramon, Goldramon and Holydramon appear, realizing that Dyson, Ken, Will, Tyler and Hikari are back.
 * The mid-credit scene shows how Dyson, Ken, Will, Tyler and Hikari recall having been away for days in the ”Hidden Dramon Lands”, but less than hour has passed in the rest of the Digital World and the real world.
 * The post-credit scene shows an unconscious boy in hospital with an active Digivice in his hand.
 * Most common themes are:
 * Taichi and Matt struggling to learn the ”ultimate fusion” of WarGreymon and MetalGarurumon into Omegamon.
 * Mimi trying to act more confident and be well-meaning person but taking too many risks and acting before asking advice.
 * Joe struggling to continue being a Chosen One and being back under the pressure of his parents after failing at few exams.
 * Sonya coming to full circle with her relationship to Piyomon, when trying to re-earn her amnesiac partner’s trust.
 * Connor struggling to be useful since he cannot solve every problem and that some problem can be figured even without his help.
 * Tyler, Hikari, Will, Milena and Jonny exploring the meaning of having Holy Digimon as partners, with Milena and Jonny also learning to true meanings of ”rising against evil” and ”fighting for justice”.
 * Meiko slowly taking first steps into being a new Chosen One.
 * Nowell being a misanthropic young man driven mad by all his past miserable experiences and therefore choosing to become even more evil and use the end of the world to avenge his suffering.
 * Ages of the new Chosen One and the High Priest of the Cult of the Dark Digital Cosmos:
 * Meiko is 17 years old.
 * Nowell is 23 years old.

Featured characters
(Numbers indicate order of appearance. Bolded characters are fought by the protagonist(s), and italicized characters feature non-explicitly, e.g. voice, silhouette, image.)

Development
CAJH wanted the fourth main chapter to bring more Ultimate Level forms of the Partner Digimon and to introduce elements that are inspired a both the final arc of the 1999 Adventure continuity and the Eternal Continent arcs of the 2020 Adventure: continuity, hoping to use it to bring Piemon, Mugendramon, MetalSeadramon and Millenniummon into the film series idea. He also expressed an idea to bring a non-manipulated purely evil human antagonist to the story, but making this human even more deranged than the Digiversum version of Akihiro Kurata. 2020 Adventure: storyline of the Digimon of the Eternal Continent battling for survival or evolution was adapted into the story as an aftermath for the destruction caused by Nidhoggmon and this also partially inspired the film’s name.

Trivia

 * Nowell Sharpe’s appearance in the film is inspired by many misanthropic characters in real-life Japanese media and partially in real-life Western media as well. Some of them include Takaya Sakaki from Persona 3, Tohru Adachi from Persona 4, Vassago Casals from Sword Art Online, and Alan Jonah from Godzilla: King of the Monsters.
 * The role of the Vademon is not only inspired by their role in 2020 Adventure: continuity, but also by Melchior Maywin Tales of Berseria who helped Artorius Collbrande with founding of the Abbey, just like the Vademon helped Nowell and Dracmon with founding of the Cult of the Dark Digital Cosmos.
 * Aside from the original Chosen Ones, who did not learn about the Crests until the events of Light and Dark, Meiko Mochizuki was introduced without her Crest being revealed yet.
 * Sigurdmon, a new Digimon species was designed to be an individual Perfect Level form for Hawkmon, while Shakoukimon (Shakkoumon in real-life Digimon media) was turned into individual Perfect Level form for Armadimon.
