Diablomon

Japanese name:

ディアボロモン

It repeatedly absorbs all the data on the Network in order to evolve and grow larger, and is depleting the Digital World to the brink of destruction. A Diablomon 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; 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. Its Special Move is firing a powerful shot of destructive energy from its chest-cannon (Catastrophe Cannon).
