Dorumon

Dorumon is a Beast Digimon and carrier of the X-Antibody whose name is derived from "DIGITAL OR UNKNOWN MONSTER". Because it has an old-style interface on its brow, it has been conjectured to be an experimental "Prototype Digimon" from before Digimon were discovered. The personality of natural Combat Species Digimon manifests particularly strongly within it, so its combat instinct is high, and it often barks and snaps at everything, but it seems that it was tamed by someone it once bit. The data that is said to have been hidden within the deepest parts of its DigiCore, during an experiment, is the potent life-force data of the legendary beast, the "Dragon", and it is said it has the potential to grow into a mighty Digimon.
