Murmukusmon is a Demon Lord Digimon whose name and design are derived from the mythological Murmur. Although it was originally a high-ranking Angel Digimon, it fell from grace and became a Demon Lord Digimon. It is in the ruling class of the Nightmare Soldiers, with the title of "Count", and it manages thirty legions of demons. Also, it is attended by the Mythical Animal Digimon Gryphonmon, which it uses as its own hands and feet.
