Dorumon appears as a small dragon with purple-colored fur. It has paws instead of claws, it has small wings on it's back, a fox-like tail, a red crystal is imbedded on his forehead.
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.

Dodomon is a Slime Digimon and a carrier of the X Antibody whose name is derived from the onomatopoeia for impacts (ドドッ "Dodo"?), and as such is a violent Digimon. Its whole body is covered in a tough fur named "Mithril Hair". It manifests an aggressive personality immediately after being born, and despite its fangs not yet being grown, it opens its mouth wide and completely intimidates the opponent with the manner in which it snaps at them. Because of this, there exist many Digimon which are completely deceived, but it is still a rare Digimon.
Dorimon is a Lesser Digimon and a carrier of the X Antibody whose name is derived from the onomatopoeia for drifting (ドリドリ Doridori?), and as such it is often running. It can run very quickly if it is going straight. It is often running wild because it hates to be domesticated, and it is dangerous because it will recklessly charge at and ram anyone who approaches it. Its ears have grown sharp and hard, and because they also act as horns there is some small damage from its ramming attacks. However, it can't turn when going at speed.
