Before time began…

So far, all of the events that have occurred are leading to the inevitable clash of these cinematic universes. However, when the universe was but a child, a great force awakened. It was Galactus, the devourer of worlds. He hungers for planets to ingest, he has set his sights on a planet filled with autonomous robotic organisms. Cybertron. Unbeknownst to him, Cybertron was being pursued by the chaos entity, Unicron.  Both powers were unrivaled in their infinite lifespan, both would be victorious in destroying Cybertron. however, there can only be one victor.  Unicron would initiate the battle but both titans would battle for a millennium until Galactus would be repelled.

Tired, and badly wounded, Unicron lay slumbering in his dormant planet form, waiting for his brother primus, to awaken once again. Meanwhile, though Cybertron had seen its rough days, that was nothing compared to the war that will arrive between the Autobots and the Decepticons.
