Story is about the arrival (or maybe better said come back) of mysterious artifact to Cybertrone. After suffering injuries in battle against unknown aliens Megatron gets himself under effect of the mysterious artifact. Soon, schism is created between Megatron and his followers [new group called Decepticons] and Optimus Prime [and remaining Autobots] who is bewildered by the very change in Megatrons behavior.

Art and story are just great – one word of warning though, all Transformer’s are based on their movie counterparts, not the cartoons.

This one is a prequel to the new film, and if you wish to get some additional background information it is a recommended read :) ( )
