Ten years have passed since Megatron disappeared without a trace, and Unicron was defeated... The Decepticons and Autobots live in a world barely held in check, striving together to develop Energon mining sites. A young guy named Kiker, who since childhood (after meeting Prime) has developed the ability to sense Energon, helps detect Energon on Earth at an Autobot base called Ocean City. At that very moment, unknown forces attack several Autobot outposts on Mars and other planets, hordes of beings resembling Transformer robots. An elite team led by Autobots' commander Grand Convoy sets out to search for the enemy, but, finding only ruins along their path, they head to humanity's home planet and engage the foe on Earth. Using their abilities, Grand Convoy and his partners easily repel the attack, but as the wise Convoy clearly understands, this is only the beginning... the beginning of a new war...
