The War for Cybertron begins with Siege, where the Autobots desperately try to keep their home world from being overrun by Decepticons. It continues in Earthrise, as Autobots and Decepticons travel to Earth to continue their war on our world. And it concludes in Kingdom, where the Generation 1 Transformers meet the Beast Warriors.
After the Prime Wars Trilogy, War for Cybertron is the next multi-line under the Transformers Generations Branding and, starting with Earthrise, with a much greater focus on cartoon-accurate classic characters.
