The Beast Wars are the melodramatically-named battles between Optimus Primal's Maximals and Megatron's Predacons on prehistoric Earth. Originally an isolated conflict between the stranded Maximals and Predacons over territory and energon, the conflict gradually became an event that would affect not only the future of the Transformers, but also the very fabric of space and time.
