Warriors of Water

The Warriors of Water are AncientMermaimon and its legacy, those Digimon whose forms the users of the Spirits of Water it left behind can take. Those who use the Spirits of Water have the ability to combine with each other or with Spirits of other elements, becoming even more powerful.
