Dorulumon

Dorulumon
Dorulumon is a Beast Digimon whose name and design are derived from the Drill and the onomatopoeia for growling (『ガルル』). It is a faithful Digimon with a chivalrous spirit. As it usually sticks to the rock-covered mountains, it often acts alone without flocking with others. The drill on its head is a hardened portion of its hair. It runs over the ground at high speeds and uses "Hit and Away" tactics as its favorite strategy, deranging the opponent by inflicting a single blow, and since Dorulumon can cope against both ground-based and aerial enemies, it can certainly be said to be an all-rounder warrior. Also, Dorulumon is able to fire its "Dorulu Cannon" in collaboration with another Digimon by changing into its "Bombardment Mode" (砲撃形態).
