Dark Emperor (Black Blood Saga)

Chaos is the primeval source of Darkness and its primary consciousness, in the ages before the mythical Keyblade War he set out to consume the worlds in Darkness only for himself to be defeated and his Divine power was broken into thirteen fragments of Darkness, his body was imprisoned within the Realm of Nothingness and his spirit was forever punished to suffer the incapability of truly living or the peace of being able to sleep as a Spiritual entity.

He tried to pave the way for his resurrection via the manipulation of Blaid Fatum Dark and Marek Dark, it allowed him to ensure that every few centuries someone of Black Blood lineage within the Dark family would be able to host his spirit, although his own weapon and Symbol of Power was destroyed in the Keyblade War while wielded by Marek Dark.

His current Vessel is Blaid Dark, and the time of his resurrection is close at hand.
