Our War Game
The result of once Infermon sucked up all the data of the network into a force of terrible power. Diaboromon hijacked a US military computer and planned to do a nuclear attack on the world, starting with Japan, (and Colorado in the dub), to kill the DigiDestined. He easily defeated WarGreymon and MetalGarurumon and then multiplied himself until there were over one million Diaboromon. However when the two Megas merged to Omnimon, his copies were destroyed and the original Diaboromon was seemingly destroyed.

Revenge of Diaboromon
However, Diaboromon in fact survived from the previous battle and three (four in the dub) years later created a mass of Kuramon that entered the Real World. Omnimon went back into the Internet to deal with him again and, with some help from Angemon and Angewomon (who held him down), he was destroyed for good. But Diaboromon intended that so that he could live on in his Kuramon as they all escaped to the Real World and fused to become Armageddemon.

Digimon Tamers
Three Diaboromon, each the fusion of a Chrysalimon mass, were among the Mega Level Digimon to fight the Digital World D-Reaper.
