User with this ability either is or can transform into an undead demon of godlike power. They are virtually indestructible beings of immeasurable might, ruling over entire dimensions and infinities of demonic and undead subjects, undoing and reshaping whole realms at the merest whim.

For all intents and purposes, they are invincible abominations of godly power, and the best lesser entities can possibly hope for is a momentary victory against their minor servants and expanding influence.
