X Program

The X-Program (Xプログラム X-Puroguramu) is a termination program initiated by Yggdrasil to eliminate 98% of digimon as a result of the exponential growth of Digimon causing the Digital World to reach maximum capacity. When the X-Program was executed by Yggdrasil, 98% of the total Digimon population was eliminated. The remaining 2% were transferred to the New Digital World where the X-Program could not reach them. However, a minority number of digimon strong enough to resist the effects of the X-Program were able to survive by changing their Digicores. The Digimon were reborn in a form that could take in the X-Program and eventually it came to a point where a program that opposed the X-Program was installed into the Digicore - the X-Antibody.
