The Successor of The Chaos Bringer

Due to some reason that may or may not involve a truck, a soul finds itself in the void and is given the mantle of Chaos as the successor of Unicron. Watch him move reality to reality to gain strength once more and perhaps finish what Unicron could not unite the entire multiverse as one! Will he succeed? What realities would he jump to? Will he have the heart to sacrifice quadrillions of lives like his predecessor? Find out! I don't own any of the characters, plots, or anything, other than a few OC characters here and there. Everything else has its original creators
