Crowmon

Yatagaramon is a fictional character from the Digimon franchise. Just like his lower form, Falcomon, he has two different designs; the original, that was featured in the Digimon Accel, and the updated/recolored one to serve as a part of Falcomon's line in Digimon Savers.

It is named after the Yatagarasu of Japanese mythology.
