Elder God
The ancient gods are a race of cold alien evil intelligences that exist in non-time non-space of swirling anti-matter 'outside' our universe. Dwarfing even Unicron in terms of power, their limitless abilities are checked only by their inscrutable motivations, and indifference to the affairs of lesser egregores that grow in the warm wet hothouse of time and space we so arrogantly call 'reality.'
The ancient gods bear a more-then-passing resemblance to the Cthulhu Mythos, and may actually be the Cthulhu Mythos. Because it is in the public domain, the Cthulhu Mythos has been incorporated within many other fictional properties.
Fiction
Cybertron comic
Ramjet was cast adrift between dimensions when Unicron's form imploded into a black hole. He found himself in the realm of the ancient gods who repeatedly destroyed and re-created his body from the inside out while toying with his spark. Bored, they cast him back into the universe he had come from.[1] Ramjet sought out his fellow herald Nemesis Prime and journeyed to the dimension Unicron was trapped in. Balancing Act
As a result of his encounter with the ancient gods, Ramjet's body was now composed of antimatter held together by the force of his will, he had a preferment connection to non-space, and his body occasionally manifests little... tentacle-things.
