The Digital World, a strange yet fascinating life filled with wonder, mystery, and survival.
It's connection to Earth is unknown, but there have been theories that the Digital World is created from Earth's communication network aka the rise of technology.
In ancient times, the Digital World was wracked by a massive war between the human-type and beast-type Digimon. It was then that the angel Digimon, Lucemon, appeared and brought the war to an end, leading to a period of peace.
Everything seems good for a while, until Lucemon eventually grew corrupted and become a tyrannical ruler as he commands all Digimon to obey him. However, ten great Digimon who embodied the ten elements have emerge and fought together against the tyrant ruler. After a mighty battle, the Ten Legendary Warriors were able to defeat Lucemon and imprisoned him below in the Dark Area, deep within the center of the Digital World, but at the cost of their lives.
In the current present time, the Digital World is in danger once again. One of the three powerful Digimon, Cherubimon, became corrupted by Lucemon's scheme. In his corrupted state, he defeated both Seraphimon and Ophanimon, thus sealing their powers away. Unbeknownst to Cherubimon, Ophanimon has managed to sent a distress message in the human world for the chosen Digidestined cadets by finding the sealed warriors and restore the Digital World.
While Cherubimon and his minions are busy of collecting every fractal code around the world, he notices that a small number of codes are being restore by the humans who have somehow awakened the spirits of the legendary warriors with the help of Bokomon and Neemon.
Takuya Kanbara; Spirit of Flame, Agunimon. Koji Minamoto; Spirit of light, Lobomon. Tommy Hibi; Spirit of Ice, Kumamon. Zoe Orimoto; Spirit of Wind, Kazemon. J.P. Shibayama; Spirit of Thunder, Beetlemon.
Displeased by this unexpected event, Cherubimon has sent out his five evil legendary warriors to retrieve the remain warriors from the humans. Grumblemon, spirit of Earth. Ranamon, spirit of Water. Arbormon, spirit of Wood. Mercurymon, spirit of Steel. Corrupted Koichi Kimura; Spirit of darkness, Duskmon.
After their struggling battles & obtaining their own beast spirits, the heroes have finally defeat the corrupted warriors and gained a new ally, Koichi and continue on before making it to the Lair of Cherubimon, waiting for them.
Despite having a disadvantage over Cherubimon, the heroes and Koichi's new dark spirit form Loweemon were victorious with the aided powers of Seraphimon and Ophanimon. Although, their victory is cut short when the Celestial Digimon told the heroes the Digital World is still in danger by a greater threat, hidden below in the Dark Area.
Impatient of waiting any longer, Lucemon has ordered his two Royal Knight Digimon; Dynasmon and Crusadermon to go retrieve the remaining fractal codes hidden around the world at all costs and in making sure no other Digimon stand in their way, they want in return to take over the world.
Despite having the best efforts of advantage number on multiple battle, the Digidestined heroes were no match for the Royal Knights as they continue to retrieve every last drop of fractal code in hidden areas. After getting the last scan of fractal code, both Dynasmon and Crusadermon have given all the codes to Lucemon, thus he emerges once again to the Digital World.
Witnessing that his two Royal Knights are having trouble in getting rid of the humans wielding the legendary warriors, Lucemon begins to take matters into his own hands.
"Your services, are no longer required." Lucemon mutters to his guards.
Lucemon then proceeds to destroy both Dynasmon and Crusader, thus absorbing their fractal codes and obtain his most powerful form; Chaos Mode. After getting his new form, he proceeds to destroy the three moons orbiting the Digital World in order to create a bridge from the Dark Area to the human world.
Both Kaiser Greymon and Magna Garurumon tries to stop Lucemon, but were defeated by his new form. Before they were going to be finished off, Koji's brother Koichi sacrificed himself take the hit and give his spirit of darkness to his brother as his spirit is scanned by Lucemon.
In anger at Lucemon scanning Koichi, Takuya bursts into flame and Koji into light, and with the help of their friends' D-Tectors, they became the ancient Digimon; Susanoomon, a being formed from all twenty spirits.
The battle begins once again as Susanoomon manages to injure Lucemon for the first. Despite not giving up of utter failure, Lucemon tries to use his paradise lost technique, but gets countered by Susanoomon.
Shocked that these mere humans have damaged him, he glared at them.
'I may have underestimate these humans, but I won't be making that mistake again.'
Lucemon then decides to afflicts Susanoomon with Dead or Alive, which comes close to destroying him. Inside Susanoomon, Koji and Takuya think over all that has happened to them, giving them strength. They willingly separate to escape the attack, then recombine to take Lucemon out. They scan his data, but only acquire his good half, which attempts to purify the Dark Area. Lucemon's evil half data, however, absorbs the Dark Area's fractal code and transforms into Lucemon; Shadowlord Form.
Everyone gives chase as Lucemon tries to get into the Human World, finding strength from their personal growth in their Journy. Lucemon ascends to the Human World through the underground train station, and electrical surges occur all around Shibuya, taking with its Lucemon's message: "You Must Choose To Follow Me Or Be Destroyed".
Meanwhile, the heroes finally catch up with him, but Lucemon regenerates too fast for them to damage, and easily repels them.
Lucemon's Shadowlord Form reaches the Human World, hurling the to the floor of the underground station. There, they lose the will to fight, concluding that Lucemon is unbeatable. Takuya, in his despair, attempts to push the fallen elevator away. His desperation summons , who helps him push the elevator over, showing that they are not alone; Bokomon points out how weird it is that the Spirits just came to life and Neemon tries pulling his waistband, thinking they're hallucinating. They give the group advice on how to defeat Lucemon as the Ten Legendary Warriors, reborn through their Spirits, show their solidarity.
Following this motivation, the group combine all of the Spirits and ancient spirit evolve into Susanoomon. Susanoomon then pulls Lucemon's Shadowlord Mode back into the Digital World and fights the powerful Digimon. Using his Celestial Blade, Susanoomon cuts Lucemon Shadow Lord Mode in half, releasing every piece of the fractal code that he took and restoring the entire Digital World. However, Lucemon's True Larva Form emerges from his destroyed puppet and stings Susanoomon. Not giving up yet, Susanoomon releases the DigiDestined and splits into the Ten Legendary Warriors, each of them in their Human Spirit form and each carrying a sword broken out of Susanoomon's cannon. Using the sword, each of the Ten Legendary Warriors slashes Lucemon's Larva Form, destroying him forever.
After the final battle, the DigiDestined have a talk with the Ten Legendary Warriors, learning that they have left lasting marks on the Digimon. With Lucemon's defeat, the Digital World is restored, now better then ever after being freed from evil. Afterwards, they are forced to return to the Human World before Lucemon's portal closes, leaving heartbroken friends behind as they go back to their own world to save Koji's brother with their D-Tectors.
Unbeknownst to every Digimon in the Digital World, Lucemon's egg is floating far away from the Digital World further and further until it completely vanished, leaving no trace.
Meanwhile in another world. . .
The digi egg suddenly appears inside an apartment. Floating above a red & orange haired girl named Sunset Shimmer sleeping in her bed, the egg slowly descend upon the girl as it sits beside her. The sleeping girl groans in her sleep as she turns and grabs a hold of the egg close to her. She then unknowingly form a small smile on her lips before sighs and continues to finally sleep peacefully with no nightmares.
