Premise: The popular 1980s toy line returns to the small screen in this 2010s adaptation of the ``Transformers'' franchise. Optimus Prime, Bumblebee and the rest of the Autobots battle Megatron and the evil Decepticons. But while battling evil and trying to defend Earth from being destroyed, the Autobots must also guard Jack, Miko and Raf -- three kids who have accidentally discovered them. Prolific voiceover artist Frank Welker, who voiced Megatron in the original ``Transformers'' animated series, portrays that character again in this series.
