Dorumon

Dorumon's Japanese name is DORUmon. His name is an acronym for DIGITAL OR UNKNOWN-MONSTER.

Due to having an old style interface on his forehead, this Digimon is gussed to be an experimental Prototype Digimon from before Digimon were discovered. Originally, the personality of a Digimon of a battle species had materialized particularly strongly, so his fighting instincts were high, and he would snap and howl at anything, but it seems that he tamed by someone he once bit. During an experiment, it was said that data has been hidden in the deepest part of his DigiCore that is the data of the strong life force of a legendary living dragon, so it is said that he has the potential to grow into a mighty Digimon. Within him is the X-Antibody, a program that makes him immune to the X Program. His birth is mysterious and his presence would turn out to affect the fate of the Digital World itself. Due to being a naturally-born X-Digimon, he is commonly ostracized by his peers.
