Here is just a bit of lore for those wondering who Unicron might be and who the creators really are. Before time itself, there was a being called 'The One' who represented order and chaos in harmony. 'The One' wanted to explore more of the universe and thus split into two beings, Unicron and Primus. Unicron representing chaos, and Primus representing order. Primus found out that Unicron was destroying (eating) planets and thus made the 'Thirteen Primes' (not going to name them all) to help him destroy Unicron. After Unicron's defeat, his body drifted into space and eventually formed the Earth's core. Primus then became one with the core of Cybertron where he gives his life to future transformers through the Allspark in the 'Well of All Sparks'. A bit of conflict started between the 'Thirteen Primes' and Liege Maximo manipulated Megatronus into killing Solus Prime. Her body unexpectedly melted to the core of Cybertron which formed the 'Well of All Sparks'. Onyx Prime, Micronus Prime, and the Thirteenth Prime willingly enter the 'Well of All Sparks' and sacrifice their lives in order to jump-start its creative processes, with the intent of creating a new race to inhabit Cybertron. Meanwhile, Quintus Prime travels into deep space with an Emberstone to create a race that would ally with future Cybertronian civilizations and thus creates the Quintessons. The 'Thirteenth Prime' comes out of the 'Well of All Sparks' reincarnated as Orion Pax who as you know becomes Optimus Prime. Cut a long story short the Quintessons made the transformers their slaves and took over Cybertron by creating their own government and laws. The transformers then rebel against the Quintessons and force them off the planet. The transformers then lived in peace. Then overtime, some transformers believed that chaos was the best way to live, whilst others thought that order was the best way to live (Autobots and Decepticons). Then the great war starts between them
