Fan:Digimon: Light and Dark (2021 film)

Digimon: Light and Dark is a fanon live-action film idea created by CAJH. It is the sequel to Digimon and the second installment of the fanfictional multimedia franchise idea and the Eight Crests Arc. 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 Digimon.

The initial story idea of Digimon: Light and Dark was released to the Digimon Wiki on March 2021. But was later removed to be reworked for a better one, with the first version of the updated story idea released on January 2022. 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.

Plot

 * The major plot points of the First Act:
 * The Chosen Children have been searching for both Tokomon and Devimon’s castle. They are also joined by Tyler Whitaker whose partner Tokomon is, but over-protected by his older brother Matthew ”Matt” Jephson. Hikari Yagami is also aware of the Digimon but has promised not to come to the Digital World with them or tell anyone.
 * New serious disturbances appear in the Network, but instead of causing these disturbances alone, the Kuramon are using by four hordes of wild Digimon, and each one led by one Ultimate Level Digimon, sent to the Network to cause blackouts around the East Coast of the United States. The digital screens also show up a countdown of 72 hours (three full days).
 * Because Devimon and the Ultimate Level Digimon are more powerful than Chrysalimon, Huckmon advises the Chosen Children not to fight them until they have further explored their Crests (Courage, Friendship, Love, Knowledge, Sincerity, and Reliability) to reach the Ultimate Level themselves. Pressured by the fact that the Chosen Children are in a hurry, Taichi tries to forcefully find a way to tap into the power of his own Crest and make Agumon super evolve.
 * Sonya feels she will be unable to use the Crest of Love because of her problems with her mother. Connor secretly feels unable to use the Crest of Knowledge because of his problems with his parents, who are hiding the fact that Connor was adopted.
 * Tokomon is revealed to live in the Village of Beginnings, well hidden in the File Island. Then the Chosen Children discover its secret location, its caretaker Elecmon is overprotective of Fresh and In-Training Level Digimon and distrustful of the Chosen Children. Tokomon, however, refuses to obey Elecmon and evolves to Patamon. Patamon even fights Elecmon and wins.
 * When Devidramon attacks the Village of Beginnings, Taichi attempts to recklessly put his own life in danger, hoping to make Greymon super evolve, but the Crest of Courage is corrupted and Greymon dark super evolves to SkullGreymon, whom Devimon lures into the Cloud Continent to cause rampage.
 * SkullGreymon causes destruction and wounds several individuals, causing Mimi to become so distraught that she fears making same mistake as Taichi did or seeing innocent Digimon die. She leaves the group with Joe, who does not want to leave her alone. Taichi’s actions and Tyler’s distaste for Matt’s overprotectiveness cause Matt to lash out towards Taichi and leave the group as well, but separate ways from Mimi and Joe. Elecmon decides to go search for Leomon.


 * The major plot points of the Second Act:
 * Taichi starts to become uncertain of himself and decides not to make any decisions unless he would understand Matt would want. He even sees nightmares.
 * Meanwhile, Matt is also starting to become uncertain of himself. He was mostly focused only protecting Tyler and trying not to show how much his parents’ divorce really did affect him during last years. He starts seeing nightmares too.
 * Mimi and Joe find Ogremon who had been challenging several Digimon to become stronger until being severely wounded by an attack of Devimon’s minions. Joe was normally very nervous about doing medical things, but this time he did manage to tend Ogremon’s wounds.
 * One day, Taichi decides to bravely face SkullGreymon alone, this time endangering himself to talk to his Partner Digimon and save him, rather than force him evolve. SkullGreymon keeps attacking, but Taichi keeps talking and showing even stronger resolution to rather lay down his life than see his Partner Digimon suffer from dark evolution. And finally, Agumon comes out of SkullGreymon.
 * SkullGreymon has become its own entity, but Taichi refuses to run away from it, purifying the Crest of Courage, and making Agumon evolve into Greymon again and then super evolve to MetalGreymon. SkullGreymon is defeated and MetalGreymon reabsords its data.
 * MetalPhantomon tries to kidnap Tyler and Patamon, and wounds Piyomon. Matt, who was convinced by Gabumon to return to help others, arrives and realizes how he is still important to Tyler, even though his brother would one day grow up. He also realizes that the other Chosen Children really do see him as their friend, making the Crest of Friendship activate. Garurumon super evolves to WereGarurumon who destroys MetalPhantomon.
 * Patamon can sense Devimon and guides the Chosen Children to one of the places visited earlier, Miasma Lake, where Devimon’s castle is submerged.

 * The Chosen Children reach the Miasma Lake, and the castle rises to the surface, and connects to the Network with a black energy pillar. They split into groups that try to fight against the Kuramon and the Infected Digimon in the Network, with Devimon himself faces with MetalGreymon and WereGarurumon.
 * Some of the Kuramon evolve all the way into Chrysalimon but do not grow into gigantic size, like the one that appeared a year ago, but the Ultimate forms of the Partner Digimon are able to defeat them.
 * Leomon is wounded by MetalTyrannomon and MegaSeadramon, and Ogremon, unwilling to let someone else finish Leomon, sacrifices himself.
 * Connor realizes that the Chosen Children appreciate his knowledge and curiosity and how he should be honest with his adoptive parents, activating the Crest of Knowledge, making Kabuterimon super evolve to AtlasKabuterimon and defeating Okuwamon.

 * Mimi realizes that she cannot avoid fighting forever and admits wanting help others to prevent them from being hurt, activating the Crest of Sincerity, making Togemon super evolve to Lillymon and defeating MetalTyrannomon.
 * Joe realizes he is there when others truly need him despite not being a leader, activating the Crest of Reliabilty, making Ikkakumon super evolve to Zudomon and defeating MegaSeadramon.
 * One Chrysalimon absorbs the data of Mammothmon, Okuwamon, MetalTyrannomon and MegaSeadramon to super evolve into Infermon who is a powerful opponent until Garudamon, AtlasKabuterimon, Lillymon and Zudomon combine their powers to destroy it. But before its death, Infermon manages to shut down every electronical device in New York, except those working with batteries.
 * A holographic phenomenon showing the final minutes of the countdown appears in both the real world and the Digital World. Devimon absorbs the data of his castle and Infermon to super evolve into NeoDevimon. Infermon’s data allows NeoDevimon to take full control of the blackouts and infections. He also launches a missile from a U.S. base in Pacific Ocean towards New York as part of his plan to ensure that the Chosen Children will never be able to restore New York if the city is destroyed.
 * MetalGreymon, WereGarurumon, Garudamon, AtlasKabuterimon, Lillymon and Zudomon are easily overpowered by NeoDevimon. Patamon tries to fight by himself but is almost killed before Tyler finally manages to make him evolve to Angemon.
 * The other Partner Digimon send their own powers to Angemon, degenerating back to their In-Training forms in the process. In the real world, Hikari, sees an image of Angemon and reaches it out. Then, Angemon uses Heaven’s Knuckle, but his body turns to data that flows with the attack towards NeoDevimon. Nothing happens at first, making the Chosen Children think Angemon failed and was destroyed. But Angemon rematerializes as Tokomon inside NeoDevimon’s body, which starts to glow.
 * Angemon uses Holy Power to re-direct the missile, stop the countdown and create a force field to prevent an electromagnetic pulse from permanently damaging any electronical devices while restoring the stolen data to the Network. After degenerating back into Tokomon, he escapes from NeoDevimon’s body.
 * NeoDevimon loses his powers but survives by degenerating into Tsukaimon. Tsukaimon laughs and decides to return to the Server Continent to meet another enemy cannot be defeated by only seven Chosen Children. He then escapes into a distortion-like gate, much to Tyler’s disappointment.
 * Elecmon promises to take care of Ogremon’s Digi-Egg and Huckmon assures the Chosen Children that the Partner Digimon will slowly but certainly regain their powers, and informs that not only must Tyler awaken the powers of the Crest of Hope, but they must also find the eighth Chosen Child.

Development
CAJH planned from the very beginning that Devimon would be the first recurring antagonist of the fan fiction film series. He also planned that Tyler Whitaker and Hikari Yagami and would not participate in battles during the first film, ”making them new members, in a way” in the sequel.

CAJH decided that Light and Dark would indeed take one school year later than Digimon, but also decided that it might not be the case with every upcoming installment of the series. He explained that he would not want to write the films or plan a production schedule for them in a way to ”exhaust” potential actors or actresses. Centaurmon was decided to be left out from the sequel, due to CAJH not coming up with any good storyline idea for him. Leomon, Orgemon and Huckmon still remain as supporting characters. And the Chosen Children’s relationships to their families were opened up even more as part of the ”Crests storyline”. As for the decision to introduce the first six Ultimate forms in the sequel, CAJH explained that he needed to ensure that every main character of the film would have a proper storyline, just like in the first film.

Trivia

 * Unlike in 2020 Adventure: continuity, this version of Soundbirdmon does not possess an ability to brainwash Digimon. That role, as well the role of Black Gears, is given to the Infection that makes its return from the first film. But only in Light and Dark, the Chosen Children manage to find a way to purify the Digimon from Devimon's Infection without any outside help.
 * This version of Devimon has minions who are familiar serving Vamdemon in 1999 Adventure continuity or Millenniummon in 2020 Adventure: continuity.
 * Mammothmon was chosen to appear due to its battle against in ”Return to Highton View Terrace” (the 29th episode of Digimon Adventure).
 * Okuwamon was chosen to appear due to its battle against in ”The Kings of the Insects Clash” (the 14th episode of Digimon Adventure:).
 * MetalTyrannomon was chosen to appear due to its appearance in Digimon Adventure: and DarkTyrannomon’s battle against in ”Flower Power” (the 35th episode of Digimon Adventure).
 * MegaSeadramon was chosen to appear due to its battle against in ”City Under Siege” (the 36th episode of Digimon Adventure).
 * SkullGreymon was initially planned not to appear, but that was changed for the benefit of the story.
 * The Kuramon were brought back into Light and Dark, to make sure their role in the original trilogy would not be too small. And Infermon was added to the plot to make the Kuramon more powerful opponent.
 * Angemon was planned from the beginning to be the one who would ensure NeoDevimon’s defeat. But because NeoDevimon was an Ultimate Level Digimon and CAJH wanted to keep using Devimon as a villain for more than just two films, Devimon’s defeat was not developed to be his end in this film.

Digimon: Worlds Collide
The third installment, a sequel titled Digimon: Worlds Collide, focuses on facing a greater villain behind the previous challenges of the Chosen Children and finding the eighth Chosen Child and the second Holy Digimon.
