Apocalymon

Apocalymon
Apocalymon is an Unidentified Digimon whose name is derived from the, the book of Christian Scripture which prophecies the end of the world. He takes the form of a blue-skinned humanoid wearing a black cape with red trimming, a grey helmet with yellow markings, and a scar on his left eye. His arms are long with black bands on the forearms and his hands are larger than normal hands, and have red claws. His hair is a dirty white, and he has yellow eyes. From the waist down is a giant polyhedron the size of a planetoid (he does have legs and can, in fact, separate from the polyhedron body) that can bring out giant metal claws on DNA-shaped chains. Filled with dark thoughts, he was born from the assimilated data of every Digimon that failed to digivolve. Although he is sealed away, Millenniummon frees him. It seems as though Apocalymon is among the most powerful Digimon in the Digital World, as demonstrated when he copies other Digimon attacks, easily destroys the DigiDestineds' Crests, and almost killing both the tamers and their Digimon.
