Hi! The DNA digivolution is implemented, it works with the digimemories that are generated when a digimon dies. e.g. You have a Wargreymon, it dies, then you grow a Metalgarurumon, when you reach the mega stage, you have the available digivolution Omegamon, one of it's requisites is Wargreymon Digimemory, and if you have it, it will digivolve
