Digimon Frontier plot summary


 * This article provides a detailed plot summary for the anime series Digimon Frontier.

In the beginning
The history of this Digital World, which lacks any explained origins for its Digimon inhabitants, is one steeped in violence. In times past, Human-type Digimon and Beast-type Digimon battled in a war against one another that threatened the world. But the day came when the angel Digimon called Lucemon, descended from the heavens and brought the war to an end, uniting the Digital World under his rule. But as the adage says, absolute power corrupts, absolutely. Lucemon became a tyrannical ruler, and ten powerful Digimon took up arms to battle and defeat him. These ten Legendary Warriors were successful in their attempt to stop Lucemon, sealing him away in the Dark Area. As time went on, with the absence of a ruler for the Digital World, three Digimon were chosen to rule ‚Äì Seraphimon, Ophanimon and Cherubimon, the Celestial Digimon, who worked together to restore peace, and to safeguard the Spirits left by the deceased Legendary Warriors.

The structure of this iteration of the Digital World is somewhat different to others we have seen ‚Äì while it remains comprised of data, all matter also possesses a Fractal Code, which gives the data its form. All regions of the world ‚Äì each representing one of the ten elements embodied by the Legendary Warriors and their Spirits - are connected by a massive global transport system of Trailmon tracks, with each region having its own Trailmon terminal for the collection and depositing of passengers. The Digital World possesses three moons, one blue, one green-yellow and one red, which were dubbed the Seraphimoon, the Ophanimoon and the Cherubimoon, respectively, after the Celestial Digimon.

The Celestial Digimon assume their roles after Lucemon was defeated and the Ancient Warriors using their data to create the Spirit of the Legendary Warriors. They were trusted with the Human Spirits: Five (Darkness, Steel, Water, Earth, Wood) were given to Cherubimon, two (Light & Wind) were given to Seraphimon, and the remaining three (Fire, Thunder, Ice) were given to Ophanimon. Cherubimon was responsible for chronicling all events of the Digital World, Seraphimon was in charged of making laws for all Digimon to follow, and Ophanimon was responsible for the nurturing of the Digital World. The peace in the Digital World would soon be broken when Cherubimon would be corrupted by Lucemon's darkness.

Start of the series
The biggest feature introduced in this season is "spirit evolution", where the Digi-destined themselves evolve into digimon to become Legendary Warriors. For this special kind of evolution, they use "spirits", artifacts created by the Ancient Warriors that were hidden in certain areas of the Digital World. When the characters first arrive in the Digital World their cellphones turn into digivices called D-Tectors. The two types of spirits are the "human spirits" and the "beast spirits." Another interesting detail lies in the way the children travel within the regions of the DigiWorld. Unlike the previous seasons, most areas are connected by railroads, where train digimon called "Trailmon" act as a means of transport.

Duskmon to Koichi
After defeating the four Legendary Warriors that serve Cherubimon, Koji discovers that Duskmon, the fifth evil Legendary Warrior, is really his estranged brother Koichi. With Takuya's help, Koji is able to free his brother from the spirit. Afterwards the Spirits of Darkness regain their true form, and Koichi can now become the true Warrior of Darkness, L√∂wemon, and joins the group.

Lucemon
After they defeat Cherubimon, the Digi-Destined learn that Lucemon, an ancient, evil, angel digimon whom the Ancient Warriors sealed away, was the one who was really behind it all. So now the Six Digi-Destined must defeat him and his two Royal Knights before they scan away all of the Digital World, which would allow Lucemon to be free.

Season finale
At the beginning of episode 50, End of the line, Lucemon is in his final mode, Satan mode, having beaten all 5 DigiDestined. They land at the train station where it all began and they were about to give up when the spirits of the Legendary Warriors came to life and encouraged them not to give up. The three celestial Digimon, Seraphimon, Ophanimon, and Cherubimon, also appeared in vision forms and informed everyone that Lucemon is evil without willpower and that they held the fate of the Digital World. All of the DigiDestined and Spirits unity Digivolve into Susanoomon and returned to fight.

They realized Lucemon has two parts in his current form: his external dragon form and an inner larvae-type form inside a sphere. They all attacked the latter, causing the former to go wild. Susanoomon formed a large sword and cuts the beast in half, releasing all the data into the Digital World. However, the inner form returned and continueed the fight. Susanoomon ejected the DigiDestined just in time, and then split up into its ten composite spirits. Using swords, they cut Lucemon up, destroying him.

The Legendary Warriors thanked the DigiDestined for everything and gradually, the Digital World returned to its full strength. The D-Tectors released data and the Digital World is slowly reborn. Strangely, the Legendary warriors even seem to have taken on some of the DigiDestineds' personality traits. To get the DigiDestined back to Earth in time, the spirits pushed the DigiDestined into a wormhole that Lucemon created before it closed. Upon returning, they realized no time has passed and they are back where they started. They all rushed off to save Koichi Kimura. The D-Tectors glowed and revived him, and then turned back into cell phones because their energy was gone. Everyone gathered around Koichi, who is fully revived. Everyone gets in a group hug, thoroughly overjoyed at Koichi's revival.
