After the terrible events of the previous volumes, the Earth and its mechanical protectors, the Autobots, heal their wounds. For their part, the Decepticons prepare a plan more evil than ever now that Starscream is out of state to harm... But can we get rid of Megatron's worthy successor as easily? Robert Kirkman and his publishing house Skybound create a historical precedent by choosing Urban Comics as partner of their new shared universe: the Energon Universe! With the creation of this universe, the screenwriter realizes a child's dream: creating a coherent and (finally) exciting shared universe between Transformers and G.I. Joe, his two favorite toy licenses.
