This animated series offers a sleek update of the classic 1980s show about shape-shifting robots from another world--the virtuous Autobots and the evil Decepticons. In this first season, the Autobots become the protectors of Earth and the all-powerful Allspark. Along with their newfound friend Sari, the keeper of The Key, they must defend their new home from the despicable machinations of the Decepticons. Gear-grinding battles with Optimus Prime, Megatron, Bulkhead, Ratchet, and others feature in this action-packed collection that presents every episode from the show's debut season.
