An Undead Digimon. When Groundramon evolved, it obtained data relating to construction equipment, and as a result sacrificed all of its organic parts, including its emotions, for pure destructive power. It is said that encountering a Breakdramon is guaranteed to result in a calamity, as it will not stop attacking until its entire body is destroyed. This fearsome reputation gives it the title of "Ultimate Destroyer Dragon" (究極の破壊竜, Kyūkyoku no Hakairyū)
