A Super-Mega Digimon born of a mutation that occurred when a large amount of Diaboromon fuse. Diaboromon has the ability to copy itself en masse, but their abilities would be less than those of the original. But by fusing that mass of copies, it was able to obtain more power than the original Diaboromon. Its special move Black Rain shoots energy beam into the air that fall like rain, and Ultimate Flare fires a destructive energy beam from its gaping maw.
