Predacon general Magmatron travels back to the era of the Beast Wars on prehistoric Earth. His mission: to pick up where Ravage failed and retrieve the rogue Megatron, but his actual plan is to gather an army from the Axalon’s stasis pods and return home to conquer Cybertron. However, Leomus Prime has inserted Razorbeast into the Predacon forces to stop him. Razorbeast manages to keep some of the awakened protoforms as Maximals and then stalls for time while he tries to contact Cybertron. Finally, the new Maximals arrive in the nick of time and defeat the Predacon forces. Magmatron is trapped in a timeless void, while Razorbeast and all the other characters settle down in the past to wait and see if Cybertron got their call and send help.
