Neptunmon is a God Man Digimon whose name and design are derived from the mythological Neptune, the Roman god of the sea. One of the "Olympos XII", it is a Digimon god of the sea which presides over all Aquatic Digimon. Though the Scalemail which covers Neptunemon's body is made of "Chrome Digizoid" converted into the "Blue Digizoid" which excels in agility, it prefers to remove it when possible due to its poor speed in the water. It constructed a castle to reside within, the "Abyss Sanctuary", at the far depths of the sea, so that only those who can withstand the water pressure of the extreme depths may enter.
