DoruGreymon

DoruGreymon is a Beast Dragon Digimon and a carrier of the X Antibody whose name and design are derived from "Digital OR Unknown Greymon". It is a massive Digimon whose form was released through the interface on its brow by the potent life-force data of the legendary beast, the "Dragon", which slept within the deepest parts of its DigiCore, and that holds the alias of "Final Enemy". With its overwhelming stature it can demolish any indomitable Digimon, and even the attacks of the "Nightmare Soldiers" are deflected with one sweep of its wing. As it is highly intelligent, it won't reveal its existence carelessly, so it is difficult to even detect it.
