Before the beginning, there was Primus and his brother, Unicron. One the incarnation of Creation, the other of Destruction. Primus and Unicron battled for eons and the balance of power shifted between them. By creating the Thirteen, the original Primes and Train-Primes who proceeded Optimus, Ryan, Ryantinel, and OpThomas, was Primus be finally able to defeat Unicron and cast him out. Primus than became one with the very core of Cybertron, giving life through the Well of Allsparks, while Unicron drifted aimlessly through space and in time, debris from space gathered around him, making the planet called Earth.
