Digimon Frontier

Digimon Frontier (デジモンフロンティア), known as "Digimon 4" in South America, is the fourth Digimon TV series, first broadcast in 2002. After prompted to do so by unusual phone messages, five children go to a subway station and take a train to the. There, they meet and, who act as their guides and tell the children that the Digital World is being destroyed, and the children must fight the evil  and his Legendary Warrior servants in order to save the world.

Plot summary
The biggest feature introduced in the season is "Spirit Evolution", where the DigiDestined themselves evolve into Digimon to become Legendary Warriors, rather than having partners. For this special kind of evolution, they use Spirits, artifacts created by the that were hidden in certain areas of the. When the characters first arrive in the Digital World, their cell phones turn into digivices called D-Tectors. Each character actually acquires two Spirits each, the "Human Spirits" and the stronger "Beast Spirits," and some transform into even stronger forms by being able to use their two Spirits at once and ultimately by combining all the team's spirits together. Another detail different from the previous series lies in the way the characters travel within the regions of the Digital World: most areas are connected by railroads, where train Digimon called "Trailmon" act as a means of transport.

When the five DigiDestined arrive in the Digital World, they find themselves hunted by five other Legendary Warriors who serve the evil. After they defeat four of the enemy, discovers that, the fifth evil Legendary Warrior, is really his estranged brother. With Takuya's help, Koji is able to free his brother, and Koichi restores the Spirits of Darkness to their true forms to join the team as the true Warrior of Darkness,.

After they defeat Cherubimon, the DigiDestined learn that the true mastermind is, an ancient and corrupt angel Digimon whom the Ten Legendary Warriors sealed away. The six DigiDestined must defeat his two before they scan away all of the Digital World, which would allow Lucemon to be free. Despite their efforts, Lucemon is freed and, after absorbing the Knights, digivolves into a stronger, more powerful form. The DigiDestined combine their power into a new ultimate warrior called, finally defeating Lucemon to save both the Digital World and the Real World.

Digital World
The Digital World of Digimon Frontier is a in which  roam.

The Digital World is divided into ten regions, each one representative of one of the world's ten elements—Flame, Light, Ice, Wind, Thunder, Earth, Wood, Water, Steel and Darkness. A massive network of train tracks crisscross the planet, with a terminal in each region, allowing the train-like Digimon, the Trailmon, to ferry passengers from one region to the next. The most distinguishing feature of the Digital World is that everything exists in the form of fractal code—the "command code" for any data. Fractal code is usually hidden, but once it is either uncovered or has its key taken, it can be "digitized," which in turn "unlocks" the data of the item or individual in question, allowing it to be manipulated. In most cases, this leads to the data being absorbed—an action frequently perpetrated by the villains of the series. Conversely, if the Fractal Code is "rendered," it restores the data to its intended shape and form and "locks" it back into place. If a Digimon has their fractal code scanned but their data is not completely absorbed, then it will reconfigure itself into a, which then transports itself to the Village of Beginnings, where, after being tended by , it will hatch out into a new baby Digimon and start its life over again.

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,, appeared and brought the war to an end, leading to a period of peace. Lucemon, however, eventually grew corrupted, becoming a tyrannical ruler, prompting the emergence of ten great who embodied the ten elements. After a mighty battle, the Ten Legendary Warriors were able to defeat Lucemon and imprisoned him in the "Dark Area" deep within the center of the Digital World.

Passing on into the realm of legend themselves and leaving powerful Spirits embodying their elements behind, the ten warriors were succeeded by a trinity of angelic Digimon known as the —, and. The group was not a harmonious one, unfortunately—the beast-type Cherubimon disagreed with many of the human-type Seraphimon and Ophanimon's policies, and made the argument one of the beast versus human. Mistakenly believing that the two human-types planned to betray him, the despairing Cherubimon found himself overtaken by the dark aura of Lucemon, and was transformed into a virus form. The evil Cherubimon then led the beast-type Digimon in a campaign against the human types, ultimately capturing Ophanimon and forcing Seraphimon into a regenerative coma.

To save the Digital World, Ophanimon calls upon children from Earth to merge with the spirits of the Legendary Warriors and become Digimon themselves to help free Cherubimon from Lucemon's influence. The new Legendary Warriors are eventually successful in freeing Cherubimon, but Lucemon, undeterred, soon gains enough power to consume the fractal code of the entire Digital World and destroy its moons. He then begins his conquest of Earth as well. In the last battle to save what remained of both worlds, the Legendary Warriors defeat Lucemon and the Digital World, and the Digimon on it, are restored.

This particular Digital World is also orbited by three Digital Moons: the Red Moon, the Yellow Moon, and the Blue Moon. At least two of the Digital Moons are inhabited: the Blue Moon has the Moon Base and the Yellow Moon contains the remnants of the Village of Beginnings.

English dub edits

 * In the original Japanese version, is portrayed as an extremely effeminate male character. In the English dub, he is simply a female.
 * is portrayed as a street-smart thug, speaking in an old downtown Tokyo accent in the original Japanese version, while in the English version he is portrayed as illiterate.
 * originally gave advice to the audience at random times, such as "Always wash your hands after using the toilet" and "When you wake up in the morning, brush your teeth" in the Japanese version. In the English version, he uses the word "Right" quite often instead and talks with a Brooklyn accent.
 * is changed from a parody of Japan's idol culture to a southern belle in the United States.
 * is much more verbally abusive in the English version than in the Japanese version.
 * speaks less in the Japanese version than in the English version.
 * In episode 6, the dub cuts out two minor scenes: the first showing a hand print on J.P.'s face after Zoe slaps him, and the second showing Koji hitting Takuya on the head with a stick. Also, in episode 5, the Minomon's tendency of suffixing their sentences with "mino" was removed.
 * In episode 9, a short scene where Tommy attacks Zoe with a burning stick (with Koji leaping in front of her to defend her), is cut from the dub.
 * In episode 11, the fraudulent fortune telling methods of Gekomon and Sepikmon were changed in the English dub. In the original Japanese version, Gekomon "uses the momentum from getting drunk on sake to tell the future", while Sepikmon hits people on the head with his boomerang and reads the cartoon stars that circle the person's head to tell their fortune.
 * In episode 13, the dub cut a scene where Grumblemon chokes Deramon.
 * In episode 15, a scene where the words "Sexy Dynamite" was shown in the background was edited out. The scene depicted Zoe Orimoto in a red bikini. The scene when Zoe is removing her shirt, she raised it a slight bit higher than the edited dub version, and shows a bit of her panties and a bit of her breasts in the original Japanese version.. Also, when Takuya and J.P run in on her after she screamed, J.P had a nose-bleed.
 * Most of the suspenseful parts in the Japanese version were talked through by soliloquies in the English version.
 * The background music in the Japanese version is different from the English version.
 * From episode 48 onwards, when the children were in the Hybrids as Susanoomon, certain parts were airbrushed out to avoid showing them nude. During the evolution to Susanoomon (Takuya and Koji only) had a key part cut to avoid showing Takuya and Koji nude as well. Later, in the final evolution to Susanoomon, the English dub re-created the entire hand motion (first 10 seconds of spirit evolution). This can be seen because Takuya and Koji have their old digivices instead of the new ones. In the original Japanese version however, they have the newer ones.

Despite these edits, the English version of Digimon Frontier, in general, is much closer to the original Japanese version than previous seasons. One example of this was to keep the Japanese term "evolution" instead of using the usual "digivolution". Other overseas dubs such as the Spanish and German dubs, use terms derived from digivolution, despite this change.-->
