>>41256405savers falcomon does the same shit as greninja, just with a different animal. much like how pokemon used greninja's tongue to naturally simulate a ninja's scarf, digimon used the coloration of falcomon's head and facial disks to naturally simulate a ninja's mask.
there's no special ingenuity with greninja, it's just a shillmon in a franchise that was already massively popular long before it existed.
