Dorumon

Dorumon is a Beast Digimon whose name is derived from " D IGITAL OR U NKNOWN MON STER". Because of the old-style interface on its forehead, it is thought that Dorumon is an experimental prototype Digimon from before Digimon were discovered. Initially this Digimon's battle-personality had manifested too strongly, but it seems that it was eventually tamed by someone it had bitten. In an experiment, it was discovered that hidden deep within its DigiCore is the data of a legendary dragon, and it is thought that this gives it the ability to grow into a mighty Digimon. It naturally carries the X-Antibody, causing it to be ostracized by its peers, but its existence will turn out to affect the fate of the Digital World itself.
