This is it folks - the grand finale. From amnesia and human mech-organ thieves to endless hunts for bits of Cybertronian tech carelessly left scattered around the globe, it all comes down to this. A climatic battle between the Autobots and the Decepticons with the fate of two worlds in the balance. The countdown that began yesterday with the start of the Transformers Prime marathon reaches its conclusion at 7pm ET with Darkest Hour, the second season finale of Optimus Prime.
