The first installment of the Transforming Robots series, "Siege," showcases an ongoing war between the Autobots and Decepticons that wreaks havoc. Megatron suggests bringing an end to this conflict by utilizing the Allspark, but Optimus Prime opposes the idea and advocates for saving the planet by destroying it. In the subsequent season, "Earthrise," the Transformers undertake a mission to locate the Allspark, sparking a new battle for supremacy between the Autobots and Decepticons on Earth. The third and final season, "Kingdom," witnesses the Autobots joining forces with their Maximal ancestors after encountering a mishap whilst en route to Cybertron. Together, they face off against the Predacons, who are the offspring of the Decepticons, in an attempt to take over prehistoric Earth and the valuable reserves of Energon.
