In a Digital World so overcrowded it's collapsing under its own weight, the god-computer Yggdrasil launches Project Ark: culling most of the population and resettling a chosen few in a freshly made world. Dorumon, a Digimon carrying the rare X-Antibody, becomes a target of the elite Royal Knights sent to enforce the purge, and only survives a first encounter when the warrior Leomon can't bring himself to strike the killing blow. Made entirely in CG rather than traditional animation, this standalone film sits outside any Digimon TV series' continuity, following Dorumon's flight across a dying world.
