Digimon X-Evolution

Yggdrasil, the host computer governing the Digital World, decides that its rapidly growing population must be reduced. The brutal X Program is released to erase countless Digimon while a new Digital World is prepared for selected survivors, turning the old world into a place of mass extinction.

Dorumon, an unusual Digimon carrying the X-Antibody, becomes a target of the Royal Knights enforcing Yggdrasil's will. As he searches for the meaning of his own existence, friendships with other hunted Digimon pull him into resistance against Project Ark. The answer hidden inside Dorumon may ultimately force even the Royal Knights to question the system they were created to protect.
