Astronus Prime

Long before the first Autobots and Decepticons, during the Age of the Creators, Astronus Prime was created as the Guardian of the Star Destroyers. His mission was to seed the cosmos with energy cores, create favorable conditions for new worlds, and regulate gravitational fields in remote sectors of the universe.
When the Great War on Cybertron spread beyond the planet and began to threaten the stability of neighboring solar systems, Astronus Prime awoke from its millions of years of suspended animation in deep space.

You argue over handfuls of energon on the burning ruins of your cities, forgetting that the universe breathes not war, but light. I have seen stars born and galaxies extinguished. Don't make me clasp my hand and turn your chaos into cosmic dust."
