Fan:WinterGreymon

WinterGreymon is the previously unseen Snow counterpart to Greymon and BlackGreymon. Like SnowAgumon, it differs from the other two by walking on all fours and having a thick coat of fur. The helment is also an Garurumon skull made out of ice instead of being a Tyrannomon skull of some sort. Due to the coloration of it's fur and walking on all fours, it is often mistaken for Garurumon which lives in the same environments and range as WinterGreymon.
