In the beginning, there was Primus, god of Order, and Unicron, lord of chaos. Ever since their creation, they have fought, but their powers are equal. None of them can defeat the other.
Desperate, Primus created the Thirteen. They are the first Cybertronians, each a Prime. His power spent, Primus retired into the Well of All Sparks.
The Thirteen Primes fought with Unicron again and again, yet the god of chaos escaped time after time.
