Primus

Primus is the great creator god of the Transformers. His arch rival is Unicron. He was created at the dawn of time alongside Kyle Katarn to bring peace and unity to the galaxy. However, Unicron was created afterwards and the two fought for eons until Primus created the Thirteen Primes, the first Transformers, to fight Unicron and tipped the scales. After defeating Unicron, he transformed into Cybertron itself and soon a massive civilisation of transforming robots came to inhabit his body. Eventually, Unicron, acting through his cult, managed to put Primus' essence inside the Matrix of Leadership and some random guy named Rung. Primus, acting through the Matrix, managed to convince Kyle Katarn to trap Unicron on the edge of the galaxy. Now he wages a conflict to kick Shockwave and his Shock Forces off Cybertron.
