Diaboromon

Diaboromon is an Unidentified Digimon whose name is derived from "Diablo" and whose design is derived from the Y2K Bug. It repeatedly absorbs all the data on the Network in order to digivolve and grow larger, and is depleting the Digital World to the brink of destruction. A Diaboromon that has absorbed a lot of data becomes convinced that it is an all-knowing and all-powerful being, and it takes pleasure in destruction and slaughter. However, when this Digimon congregates in great numbers, its raison d'être is made clear, and as that ultimate goal is to hijack a military computer and try to destroy the Real World as well with a nuclear strike, this is a terrifying Digimon.
