SkullGreymon is a Skeleton Digimon. It was a Digimon that put too much importance on fighting, and as a result of its combat instinct, it clung to life despite its body rotting away, its whole body becoming nothing but bones. As it doesn't have even a scrap of intelligence to balance its combat instinct, its existence is a threat to other Digimon.
