Plot

 * The major plot points of the First Act:
 * Another year has passed. The Chosen Children have been exploring the Server Continent in search of the eighth Digivice which would help identify the eighth Chosen Child and the eighth Partner Digimon. They have also been searching for Tsukaimon who escaped the last battle a year ago. The Partner Digimon have regained their strength and can remain in Rookie forms again. But for some reason, Tokomon is still in his In-Training form, much to Tyler’s frustration.
 * They have finally managed to locate an entire city filled with several moats full of miasma. Tokomon senses Tsukaimon being in the city, but he also senses something much darker being there as well. The Chosen Children decide not to attack the city yet.
 * Leomon has been gathering more members to his resistance group, including Spadamon who becomes his personal apprentice. After they finally meet with the Chosen Children, they start planning an attack with Huckmon’s help.
 * Huckmon himself had been making research on a prophecy written by the Kernel itself, revealing how only the power of the eight Crests is the key to destroy the evil Digimon who rules the city.
 * On the day the Chosen Children and the resistance group finally attack the city, Tsukaimon himself appears, attacking and biting all the Partner Digimon. He also summons Splashmon.
 * Taichi, MetalGreymon, Connor, AtlasKabuterimon, Mimi, Lillymon, while Matt, WereGarurumon, Sonya, Garudamon, Joe and Zudomon try to enter the city where they face LadyDevimon, one of high-ranking Dark Digimon working for the lord of the city. Tsukaimon himself faces Tyler and Tokomon who are not planning to let him escape this time.
 * After losing fight against Splashmon, MetalGreymon is almost dragged into the miasma, but learns to change into Alterous Mode. Tokomon also finally evolves back into Patamon. Tsukaimon becomes enraged, and an energy burst from the castle in the center of the city makes him evolve back into Devimon.
 * Before the Chosen Children can enter the main gate of the castle, the dark clouds appear and create a force field where daylight is replaced with a night sky and red moon. A wooden wagon, moving all by itself, appears. It opens, revealing a coffin. A voice of the ruler of the city is heard through it, echoing in the air. Devimon, LadyDevimon, and the other Dark Digimon bow before the coffin, which opens and reveals the ruler: Vamdemon.
 * Vamdemon easily overpowers six Ultimate Level Digimon, with Patamon being unable to help the others because he has not regained his ability to evolve into Angemon. Vamdemon also has the eighth Digivice is his possession to track down its rightful owner from the real world.
 * After DeathMeramon informs that the forces are ready, Vamdemon starts repeating an incantation and black sparks start appearing from his body. This opens several distortions within the walls of his city. And the distortions lead to the real world.
 * When DeathMeramon and Vamdemon’s forces start crossing into the real world through the opened distortions, the Chosen Children try to stop Vamdemon from going through. Vamdemon uses energy coming from a large well in the cellar of the castle to evolve a Devidramon into DracDevidramon.
 * Others try to stop Vamdemon, Devimon and LadyDevimon from walking through, but DracDevidramon manages to trap WereGarurumon and almost kill him. However, WereGarurumon learns to change into Sagittarius Mode and kill DracDevidramon. But by that time, Vamdemon, Devimon, and LadyDevimon manage to cross over to the real world, after which Vamdemon closes the distortions. The force field disappears, turning the night sky with red moon back into the daylight sky.


 * The major plot points of the Second Act:
 * The Chosen Children reach the real world through regular DigiGates, bringing their Partner Digimon to the real world for the first time in the process. Vamdemon’s forces have already started capturing human families around New York in order to use the eighth Digivice to figure out the identity of the eighth Chosen Child. And the mere presence of the Digimon is causing electrical disturbances in the city.
 * After fighting some Infected Digimon, Taichi and Hikari return to Queens, but their parents are captured right away. Sonya’s mother, Mimi’s family and Joe’s parents end up captured too. Matt’s father, Connor’s adoptive parents, and Joe’s older brother Jim manage to avoid capture and are told by the Chosen Children about their activities. The Chosen Children also reveal how much they have changed during these last twenty months.
 * Wizardmon, a servant of LadyDevimon finds the Chosen Children’s hiding place and tries to explain that he is on the Chosen Children’s side. The Chosen Children don’t believe him until Huckmon appears and reveals that Wizardmon is a spy working for him. Wizardmon also reveals that he stole the eighth Digivice from Vamdemon.
 * The glow of the Digivice reveals Hikari as the eighth Chosen Child. It also shows image of Tailmon, Hikari’s destined Partner Digimon and the same cat-like Digimon Hikari had seen a year ago. Wizardmon has a partial memory loss, but he still remembers fighting on the same side with Tailmon in past life, therefore believing that it is his mission to help save her. But before he can reveal what Vamdemon has done to Tailmon, LadyDevimon and DeathMeramon find their hiding place and attack.
 * During the fight, MetalGreymon, Garudamon, AtlasKabuterimon and Lillymon destroy DeathMeramon, while others purify some of the Infected Digimon that attacked as well. Patamon also regains his ability to evolve into Angemon. But LadyDevimon is still too strong opponent for the Chosen Children.
 * Hikari sees an image of Tailmon suffering and decides to surrender to LadyDevimon, in hope of finding the Digimon and avoiding others being hurt. Wizardmon, to avoid his cover being blown, leaves with them. Taichi, Matt and Sonya try to stop her, but Huckmon tells them to let Hikari go, revealing that there is a reason she must surrender.
 * The Chosen Children and their parents believe Wizardmon betrayed them and are angry at Huckmon, who decides to reveal what happened four years before the Chosen Children first arrived:
 * The powers of the Crests had been scanning children around the world, looking for eight candidates living as near each other as possible. Taichi, Matt, Sonya, Connor, Mimi, Joe, Tyler, and Hikari used to live in same neighborhood four years ago. That is when Kernel and the Crests chose them.
 * Huckmon was tasked to build the Digivices, but Vamdemon found the Holy Ruins and attacked. Huckmon managed to send six of the Partner Digimon’s Digi-Eggs away. But while Huckmon was sending away Patamon’s Digi-Egg, Vamdemon tried to corrupt it and Tailmon’s Egg. He succeeded in corrupting Tailmon’s Digi-Egg but accidentally split Patamon’s Digi-Egg into two Digi-Eggs, one pure and one corrupted. After turning Huckmon into stone, Vamdemon forcibly hatched the Digi-Eggs and evolved the corrupted the two Digimon into Devimon and LadyDevimon.
 * Vamdemon, Devimon and LadyDevimon had continued the interrupted mission of the previous Dark Digimon to bring forth greater darkness than ever before, to cover both the Digital World and the real world. But they needed large amount of data and power. For that purpose, the Core of All Digital Darkness, the very force that ensures the existence of the dark side of the Digital World, had activated the Black Sparks to start the Infection and the Kuramon Outbreak. While the Chosen Children destroyed Chrysalimon, Devimon and Vamdemon became powerful enough to Infect wild Digimon by themselves.
 * By researching and absorbing the distortive essence of the Kuramon and the Infected Digimon, Vamdemon learned a way to open a portal to the real world all by himself and has now invaded it.
 * Hikari was meant to surrender because only she can restore Tailmon and destroy LadyDevimon. Tyler and Patamon, on the other hand, must purify Devimon. Despite Patamon slowly regaining power, Tyler still doubts himself. Huckmon receives a telepathic message from Wizardmon, who tells where Hikari is being kept. Huckmon supplies the coordinates to Connor’s tablet computer.


 * The major plot points of the Third Act:
 * Vamdemon summons energy from the Well of Darkness to super evolve Devimon into NeoDevimon once again.
 * Vamdemon attempts to attack, but the eighth Digivice starts glowing, and the image of Tailmon reappears, speaking for the first time, to protect Hikari. Wizardmon reveals his true colors as well and steals the Digivice, giving it to Hikari. Tailmon gains a physical body and attacks Vamdemon. Vamdemon, however, easily defeats her and throws Wizardmon out of the building.
 * The Chosen Children save Wizardmon from falling and attack the building where Vamdemon, NeoDevimon and LadyDevimon are. Huckmon transports Leomon, Spadamon, and the resistance force to fight the Infected Digimon. Matt, Sonya, and Joe remain behind to purify the Infection and Connor to send the purified Digimon back to the Digital World through DigiGate.
 * After all Infected Digimon are defeated, all eight Chosen Children try to attack Vamdemon who starts spread dark clouds with purple lightnings from New York into the whole world. But NeoDevimon interrupts Angemon while LadyDevimon interrupts Tailmon, forcing the other six Partner Digimon face Vamdemon by themselves. Vamdemon changes into bestial Winged Mode to gain access to its other abilities.
 * Despite no longer having the same powers as in their last confrontation, NeoDevimon defeats Angemon and tries to directly attack Tyler. Leomon throws himself between and is mortally wounded. The Chosen Children are horrified when Leomon’s body dissipates because they were told that a Digimon who dies in the real world cannot reformat into a Digi-Egg. Tyler, after having failed to destroy Devimon three times and blaming himself for Leomon’s sacrifice, falls into total despair, causing Angemon to be shrouded in darkness and be absorbed by NeoDevimon.
 * NeoDevimon then calls upon the Well of Darkness in Vamdemon’s castle to send a lightning to mega evolve him to the Mega Level, so he could become powerful enough to overthrow Vamdemon. But instead of being furious, Vamdemon is laughing. NeoDevimon was too arrogant to realize he was not strong enough to control this power, so he mega evolves into a mindless DanDevimon who devours Tyler.
 * Tyler’s losing the control of his Crest reminds Taichi of Agumon’s past Dark Super Evolution into SkullGreymon. He and Matt realize that the only way to save Tyler is to go inside DanDevimon and make him regain the control of the Crest of Hope.
 * Taichi, MetalGreymon, Matt, and WereGarurumon they try to make it to DanDevimon. Vamdemon tries to stop them by keeping them busy with Night Raid attack. Then, he sends another Night Raid against Hikari and Tailmon. Wizardmon throws himself between and is bitten to death by Vamdemon’s bats instead. Before his death, he assures he did not regret dedicating his life for saving Tailmon, and encourages them not to let his and Leomon’s deaths to be in vain.
 * Hikari is crying but manages to activate Tailmon’s super evolution into Angewomon. Angewomon battles against LadyDevimon for a while, before finally destroying her with Heaven’s Charm and reabsorbing her data. After that, she and Hikari decide to respect Wizardmon’s dying wish and save Tyler from DanDevimon.
 * Hikari and Angewomon assure Tyler that Leomon’s and Wizardmon’s deaths are the very reason they still must defeat Devimon and Vamdemon. Huckmon blames himself for those two deaths because he was unable to protect Patamon’s and Tailmon’s Digi-Eggs from Vamdemon and to prevent the births of Devimon and LadyDevimon. But he believes that the Chosen Children can still prevent something far worse from happening as long as they do not give up.
 * Tyler becomes encouraged and frees Angemon from inside DanDevimon’s body. Angemon also super evolves into HolyAngemon. Due to him and Angemon being split again, DanDevimon’s body becomes severely weakened and unstable, and HolyAngemon destroys him with Holy Sword. HolyAngemon and Angewomon also combine their attacks to pierce Vamdemon’s body.
 * Vamdemon, whose original plan was to conquer both the Digital World and the real world for himself and overthrow the other Dark Digimon, suffers a villanous breakdown and refuses to accept defeat and taps into the power of the Well of Darkness, deciding to rather give up his goal and sanity rather than let the Chosen Children win. This causes Vamdemon to mega evolve into a gigantic semi-mindless Digimon named VenomVamdemon.
 * All Ultimate Level Partner Digimon try to attack VenomVamdemon, but he is too large, he is a Mega Level Digimon, and his is not unstable like DanDevimon’s. VenomVamdemon existence also accerelerates the spreading of the dark clouds and the malfunction of all digital technology around the world. Only another Mega Level Digimon would be powerful enough to destroy VenomVamdemon.
 * Huckmon reveals one last segment from the prophecy, revealing that ”the Undead Demon King shall perish by the hand of the all eight Crests spearheaded by the loved ones of the Angels”. The Chosen Children realize that the ”Angels” refer to Tyler and Hikari and ”their loves ones” to their older brothers Taichi and Matt. Addressing their feelings and resolutions, Sonya, Connor, Mimi and Joe connect the power of their Digivices with Tyler’s and Hikari’s, who in turn connect that power with Taichi and Matt.
 * The feelings of courage and friendship from all eight Chosen Children mega evolves MetalGreymon Alterous Mode into WarGreymon and WereGarurumon Sagittarius Mode into MetalGarurumon. The two Mega Level Partner Digimon are challenging opponents for VenomVamdemon but he is still not defeated.
 * After a lengthy battle, HolyAngemon and Angewomon weaken VenomVamdemon with Holy Disinfection and Saint Air, after which HolyAngemon opens Heaven’s Gate, with Angewomon using her powers to amplify its ability to suck evil data inside. Garudamon, AtlasKabuterimon, Lillymon and Zudomon try to wound the enemy and push him through the gate. When they finally find VenomVamdemon’s weak spot, WarGreymon and MetalGarurumon launch Gaia Force and Cocytus Breath to finally destroy VenomVamdemon’s body, with Vamdemon’s data flowing through the gate where it is completely purified. Without Vamdemon and his bond to the Well, Vamdemon’s city in the Server Continent collapses, destroying the Well.
 * But the disapprance of the dark clouds and distortions caused by Vamdemon makes the Partner Digimon lose their ability have physical forms in the real world, so they must return to the Digital World...until someone could figure out a way for them to exist in the real world too. Connor immediately starts developing it.
 * The Chosen Children are aware of other evil Digimon existing besides their previous opponents, and convince their parents to give their blessings for their activities. Spadamon becomes the new leader of Leomon’s resistance group.
 * At the ending scene, the Chosen Children have another adventure in the Digital World again when the next summer begins. The ending scene is partially inspired by the intro of 1999 Digimon Adventure series.


 * The mid-credit scene:
 * The Core of All Digital Darkness sends a powerful black lightning into the remains of Vamdemon’s castle and the Well of Darkness. A mysterious crystal rises out of the rubble. The crystal then flies up into the Network, where the Core is located. Then, a large yellow-eye appears in the Core.

Development
CAJH originally planned to fully make Tyler Whitaker and Hikari Yagami become Chosen Children and introduce Patamon and Tailmon at the same time. But after starting to rework the fan film writing idea, he finally decide to split them into two separate storylines out of respect for the real-life 1999 Adventure and 2020 Adventure: that Hikari should become a Chosen Child later than others.

The original idea was setting the story only six months after the events of Light and Dark. It was based on a wish that Worlds Collide would be shot back-to-back with Light and Dark and how the release dates of the two films would be at most one year from each other. But the plan changed after wards, and Worlds Collide was set a whole year after the events of Light and Dark.

Trivia

 * Vamdemon was chosen to be a major antagonist in the Adventure Saga and this film due to his arc in 1999 Adventure series being longer and more iconic than others, and also due to him being the main antagonist on Digimon Adventure 02.
 * Devimon and LadyDevimon being Vamdemon’s servants was inspired by PicoDevimon (DemiDevimon in English dub) and Tailmon (Gatomon in English dub) being Vamdemon’s servants in 1999 Adventure continuity, although Tailmon only served Vamdemon due to her amnesia.
 * Devimon and PicoDevimon being separate characters and Devimon being his own master in 1999 Adventure continuity served as an inspirator for storyline to plan overthrowing Vamdemon.
 * LadyDevimon’s role is also based on SkullKnightmon’s role in 2020 Digimon Adventure: continuity.
 * DanDevimon and VenomVamdemon were both planned to appear from the start. They were first planned to be used in the cancelled film idea World Disaster alongside Nidhoggmon, who ended up being ultimately left out of the Adventure Saga.
 * DanDevimon was planned to appear, because NeoDevimon had also been used in the film series.
 * Vamdemon Winged Mode who is like an anthropomorphic vampire bat with arms being separate limbs from the wings is an original idea to the film series. It acts as Vamdemon’s equivalent to MetalGreymon’s Alterous Mode and WereGarurumon’s Sagittarius Mode, as well as being an intermediate form between Vamdemon’s regular form and VenomVamdemon.
 * Vamdemon’s villanous breakdown and deciding to partially lose his sanity on purpose while mega evolving into VenomVamdemon was partially inspired by the scene in Persona 5 in Goro Akechi using Loki to make himself to go berserk.
 * VenomVamdemon being much bigger than DanDevimon and having partially retained some of his own sanity is based on his stronger will and the fact that Vamdemon is not a dark side embodiment of a Holy Digimon, like Devimon and LadyDevimon are.
 * The ending scene of the film was executed in a way that it could work as some form of ending for the Chosen Children’s story if no further film ideas would exist, even though the mid-credit scene teases their future enemies of the next potential films.
 * Millenniummon (in form of MoonMillenniummon) and Negamon (in form of the Core of All Digital Darkness) were teased at the mid-credit scene to set the former as the next major villain, and the latter as as the overarching villain of the Adventure Saga. The latter set-up is partially inspired by how mid-credit scene of The Avengers set up Thanos as the main villain of the Infinity Saga of the Marvel Cinematic Universe.
