Just some quick IceGreymon doodle to show basic design updates and backstory.

Opal, my Digimon Tamer form, has successfully Biomerged with Betamon- but due to pent up anger, becomes the monstrous IceGreymon instead of Plesiomon! IceGreymon's only half the size of a regular SkullGreymon (which is half the size of BKSkullGreymon, making Icey here one quarter the size of the most feared Digimon, but that's pointless.)

Now, knowing Opal won't hurt them, other Biomerged Tamers often make immature jokes like "Wow, that's one small boner!"
