Icemon

Icemon is a Champion Level Icy Digimon that has the appearance of Gotsumon, but is capable of ice attacks. Because few Gotsumon digivolve into Icemon, it is puzzling and not much is known. There is no obvious difference between it and Meteormon, although Icemon is a pale shade of blue, while Meteormon is off-white.
