Digital Monster X-Evolution

Digital Monster X-Evolution is the 8th Digimon movie, and the first to air on Japanese television rather than being in Japanese theaters first.
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. It is frequently referred to among fans by the commonplace portmanteau, "Digimon X-Evolution".

Story

The Digital World is becoming so overpopulated that the super computer (Yggdrasil) that governs the Digital World can't handle it anymore. His solution? Wipe out the vast majority of the Digimon with the X Virus. He chooses a very small percentage to be moved to a new Digital World because he plans to destroy the old Digital World. Those who were not chosen but survived anyway and moved to the new world had a rare gift known as the X-Antibody, this antibody when activated changed their appearance and made them more powerful. Those who have the X-Antibody are generally distinguished by the X in their name and sometimes an X placed on their body somewhere (for example Tokomon's X on the forehead). There are few with the X-Antibody that are not distinguished by an X after their name but this is because there is no other version of them in existence that doesn't have the X-Antibody so there is no need to distinguish the normal and X-Antibody apart with the X surname. Yggdrasil is protected by the Royal Knights, incuding Omnimon, Gallantmon and Magnamon, who eliminate X-Antibody Digimon.

One of the outcasts is a strange dog-like Digimon named Dorumon. Dorumon seems to be rejected by every body, and is attacked by a Leomon who wants his X-Antibody. Leomon eventually dies and asks Dorumon to live for him. WarGreymon X tries to make peace with a group of normal Digimon, but Omnimon shows up and eliminates them all except WarGreymon X and Tokomon who escape. The two crash land at a temple where Dorumon lives. WarGreymon X leaves Tokomon in Dorumon's care and draws omnimons fire. Omnimon fights them later, seriously wounding Tokomon and Dorumon. MetalGarurumon X and WarGreymon X shows up to battle Omnimon. MetalGarurumon X is mortally wounded and dies, giving his X-Antibody to the injured Tokomon. Dorumon digivolves into Dorugamon in response to Omnimons assault. WarGreymon X draws their fire and just before Omnimon attacks Gallantmon intervenes. Gallantmon believes Yggdrasil is eliminating all Digimon, but dies when he is impaled by Omnimon's blade. Magnamon later kidnaps Dorugamon and extracts his DNA.

Dorugamon is left for dead in a junkyard and is taken into hiding by WarGreymon X's troops, including Wizardmon, Mummymon and Silphymon. The forces of Yggdrasil later attack and the Digimon defend themselves, Dorugamon eventually digivolving to his Ultimate Level. Gallantmon X and MetalGarurumon X later return from the dead to help battle. Gallantmon opens the way to Yggdrasil's domain where Omnimon and Magnamon await. Omnimon dismembers Dorumon, who digivolves into Alphamon. Omnimon turns against Yggdrasil and teams up with Dorumon's true form, Alphamon, to restore the Digital World. Yggdrasil is destroyed at the cost of Alphamon's life. He gives his X-Antibody to Omnimon who becomes Omnimon X. Alphamon is de-digivovled to Dorumon, who returns home to find Tokomon waiting for him.
