Digital Monster X-Evolution

Digital Monster X-Evolution (デジタルモンスター ゼヴォリューション) is the 8th Digimon movie, and the first to air on Japanese television rather than being in Japanese theaters first. It aired on January 3, 2005, at 7:15 a.m. UTC+9/JST on the Fuji TV network.

Digital Monster X-Evolution is also the first and, so far, only Digimon movie to be done entirely in CG, as well as the only Digimon movie not related to one of the Digimon anime series.

X-Evolution is loosely based on the storyline of Digimon Chronicle, which was a series of mini-manga which accompanied the Japanese toy Digimon Pendulum X. The one significant difference between the manga and X-Evolution is that while the manga chronicles the adventures of Kouta Doumoto and his Digimon Dorumon, the movie's only focus is on a lone Dorumon, with no human involvement whatsoever.

Synopsis
The Digital World is becoming so overpopulated that the super computer Yggdrasil who governs the Digital World can no longer handle it. Its solution is to wipe out most of inhabitants with the X-Virus. Yggdrasil chooses a very small percentage to be moved to a new Digital World and then proceeds to destroy the old one. Some Digimon who were not chosen survived anyway, and they moved to the new world with a rare gift known as the X-Antibody; this antibody changed their appearance and made them more powerful, at the same time making them immune to the X-Virus. No longer in control, Yggdrasil uses the Royal Knights to destroy the X-Antibody Digimon, who are outcasts in the new Digital World.
