Knowing that the 'All Spark' gave them life - what is the backstory to the TF creation you would write for a live action film? Also, I have not seen ROTF yet, its out tommorrow, so easy on spoilers if possible. Personally, going off TF1, I would go for: The TFs were inanimate objects. Manufactured goods used by the Quintessons - a race of bio-mechanical beings, wallowing long in luxury. The transforming ability and AI were incorporated to facilitate manual labour as well as transportation and defense in a complete package. They were programmed products. Then, a cube fell to the planet Cybertron, a planet the Quintessons used as a staging ground for research and testing. It endowed the TFs with life and the ability to reproduce new conciousnesses. Early sentient TFs were punished for their 'crime', being free thought, and upon examining the cube and dissecting TFs, the Quintessons made a remarkable discovery. The cube contained the conciousnesses of a long dead alien race, a race of two warring factions that in a last attempt at self preservation, combined their conciousnesses in a scrambled memory cube in the dying days of their world. They never learned to control the Cube's power and fearing the sentience granted to their creations, the Quintessons fled with the Cube to their massive artificial planet, a huge factory, in the hopes of unlocking a cure. This backfired and the entire planet as well as countless individual machines became sentient. The TFs created in this manner spread across the universe and the factory, whose AI was named by the Quintessons as Unicron (UNanimous Independant Cybernetic Research OmNibus), was born in the far reaches of space. The Quintessons set a self destruct and fled in their ship to their homeworld, Quintessa. They blasted the cube into deep space out of sheer desperation and vowed to never divulge its' secrets. The vengeful Unicron, now damaged after the self destruct, slow and lumbering, followed their trail across space, consuming planetoids and moons to fuel and heal his massive bulk. He was soon forgotten. On Cybertron, the TFs were forming a society, though initially promising, the society crumbled in only a few months as the newly formed Decepticons, under Megatron, started to wreak havoc on the TF homeworld.
