The ChronoCore is a digital lifeform which serves as the main antagonist in Digimon World Dawn and Dusk. It is a sentient virus which degrades and destroys all data in the Digital World. It improved itself with the Digi-Entelechia produced by Calumon, then set out to take down Yggdrasill and rewrite the Digital World, in order to make the Digital World itself perish.
Digimon World Dawn and Dusk
The YMIR Project was started by CITY long ago in order to set a lifespan on Digimon in order to make them evolve like humans. Although the project was canceled, it produced the “Chrono Data” in the form of the Super-Ultimate Digimon, Chronomon Holy Mode. When Chronomon was forced into its destructive DM form, the “ChronoCore” virus was produced. This virus had the end-goal of taking down Yggdrasill and rewriting the Digital World.
