Koromon is a Lesser Digimon whose name is derived from the onomatopoeia for something round and rolling (ころころ Korokoro?), and as such is small and round. It is a tiny Digimon that shed the fuzz covering its surface, and whose body grew even bigger. Although it has become able to move around more actively, it is still unable to battle.
