A skeleton Digimon made entirely of bones. Obsessed with fighting and has survived on its innate ability in battle while lacking flesh and muscle, turning it into a Greymon. SkullGreymon only has fighting instinct, lacks intelligence, and is very menacing. Its special move is a barrage of organic missiles from its spine. Recent research has achieved Digivolution of the Oblivion Bird which is an improvement of these missiles including a tracking system and better power and scope.
