Digimon Tamers: Runaway Locomon

Runaway Locomon is the 6th Digimon film. It was released after the end of Season 3, and is in continuity with the series, following immediately after the Message in the Packet audio drama.

Plot
This takes place after the series finale (technically, six months after the D-Reaper was destroyed in the time slot); in it, the Tamers are planning to throw Rika a surprise party, but Rika finds out. Suddenly a train-Digimon named Locomon begins to race around the tracks, causing havoc. The Tamers respond to this, as Takato digivoles Guilmon into Growlmon to stop the train Digimon but fails as Takato, Rika and Renamon get on it in an attempt to slow it down. The others, excluding Suzie, use a freight train to catch up with Locomon

Mitsuo Yamaki takes over command of the rail centre, noticing that Locomon's path is creating a distortion in the digital field -- in other words is creating a very large digital zone. He has the railroad workers manually divert the tracks at station 9 to redirect Locomon back to the Digital World.

It is then discovered that who was being controlled by Parasimon. In the end Gallantmon destroys the Parasimon that was controlling Locomon but not before it sends a signal to start an invasion. Gallantmon, MegaGargomon, Sakuyamon, Justimon, Guardromon, MarineAngemon and Beelzemon Blast Mode fight the invasion but are seriously outnumbered. They finally win when Takato's determination causes Gallantmon to Mode Change into Gallantmon: Crimson Mode and Gallantmon: Crimson Mode destroys all of the Parasimon in one shot with his Crimson Light attack. Locomon returns to the Digital World and the entire gang attends Rika's birthday party. The movie served to provide insight on Rika, and also to confirm that the Tamers were, indeed, reunited with their Partners after the series ended.

English translation
Runaway Locomon was dubbed into the English language around 4 years after the Japanese broadcast of the film. However, as the production rights had been transferred to Disney from Fox (following the demise of the Fox Kids block, on which Tamers was the last season of Digimon broadcasted on that network), the film's title song was replaced with the theme song for the English version of Digimon Frontier, as Disney didn't possess the rights to use the theme song that was licensed to the first three seasons on Fox. However, it reunited the entire English cast of Season 3; it was also one of three re-dubbed Digimon films that were premiered on Jetix during the fall of 2005, including Battle of Adventurers and Diaboromon Strikes Back.

Production Notes
Chiaki Konaka states in his character notes (for Rika) that he "was not consulted" on Runaway Locomon, which possibly explains certain continuity errors. On this he also says:
 * "However, ...Mr. Tetsuharu Nakamura [the director], [who was] an assistant director of the TV series... [and] Mr. Hiro Masaki,... a regular writer for the series... paid a great deal of attention to the psychological aspects of the series when completing the movie... I am very grateful to them for boldly illustrating the parts of Rika's family life that the TV series never explored."

Some differences include the fact that in the English dub, the music for Biomerge Digivolution was used for the DigiModify and normal Digivolution sequences. The dub-altered Digivolution text on the Digivices looked noticeably different and less digital from its appearance in all other dubbed Tamers media, even different in how it appears across the screen, doing so in a sweeping manner as opposed to each letter flashing.

Edits

 * In the movie "Runaway Locomon", some of the Biomerging sequences were edited, as well as Gallantmon's graphic impaling of the main Parasimon's eye, MegaGargomon blowing the Parisimon into pieces, and Gallantmon impaling a Parasimon and tossing it at another.
 * At the end, when Suzie and Rika's mom sing, in the Japanese Version, Suzie sings a part of "The Biggest Dreamer" (Opening of Digimon Tamers), and Rika's mom sings a part of "My Tomorrow" (1st Ending of Digimon Tamers).
