Skullgreymon

SkullGreymon is an Undead-type Digimon and, at the same time, a Skeleton-type Digimon. Its name and design are taken from the words Skull and Greymon. Its form is quite terrifying and terrifies all Digimon who see it, as its power is so great that even it cannot understand it. This fact, combined with its uncontrollability, makes it a dangerous and deadly Digimon to face.
This is a Skeleton Digimon whose body has become mere bones. The origin of this life form is primarily due to its placing too much importance on combat, and as a result of its combat instinct, it clung to life despite its rotting body. Since SkullGreymon lacks even a shred of intelligence to balance its combat instinct, its existence is a constant threat to other Digimon.
