Warriors of Flame

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