Previous Transformers animated series have offered some details about life on Cybertron millions of years before the Autobots and Decepticons came to Earth. Later this year, the new animated film Transformers One will flesh out that history and reveal where things went wrong for former friends turned bitter enemies, Optimus Prime and Megatron. Now, on the first day of Comic-Con, Paramount welcomed fans to Hall H with some exclusive clips from Transformers One.

The first clip featured Optimus and Megatron when they were still Orion Pax (Chris Hemsworth) and D-12 (Brian Tyree Henry). Orion arranged for himself and D-12 to watch a prestigious race on Cybertron. Sentinel Prime is treated like a celebrity by the crowd and it's mentioned that the Matrix of Leadership has been missing for 50 cycles, and energon is rare.

Orion brashly enters himself and D-12 into the race even though they can't transform like the other contestants. They do well at first, but ultimately the pair have to shoot themselves out of a cannon in order to get third place. The fact that they're both miners makes them instant favorites with the crowd.
