A skeleton-based Digimon from which his
entire body is nothing but bone. A SkullGreymon is
formed when a Digimon spends too much important time
fighting, eventually preferring to live only through his
or her fighting instinct even after his or her death.
SkullGreymon has no intellect at all but plenty of
fighting instinct, and his entire existence alone poses
a threat for other Digimon. His special attack is
"Ground Zero", which launches an organic missile from
his spinal cord.
