Beyonders

The Beyonders were an incomprehensibly powerful race of extra-universal beings from the Marvel Comics books. They inhabit 'White Space', the void outside the Multiverse, and are even known as the 'White Lords of Wild Space', and as the 'Sinnu Sarrum' or 'Ivory Kings'.

They are beings of indescribable power, who occasionally send 'packages' of reality-altering power into the Multiverse as an experiment; these 'packages' are known as 'Cosmic Cubes', and they bestow godlike power on their wielder. Eventually, such Cubes develop into - equally potent - beings in their own right. One such being was known as the Beyonder himself, although his Cube-related origin was not revealed until much later.

Viewed as essentially benevolent at first, the Beyonders were eventually revealed as cruel and destructive when they decided the 'experiment' of life had run its course and they plotted to destroy the entire Multiverse. They found their nemesis in Doctor Doom, who, taking the alias Rabum Alal - or 'Great Destroyer' - eventually found a way to seemingly annihilate the Beyonders by turning their own power against them.
