Despite his nemesis's numerous machinations, the Predacons were defeated and Megatron brought back to Cybertron. Optimus Primal was soon reborn in a Transmetal body and was later granted a more powerful body after taking Optimus Prime's spark into his body to foil Megatron's plans to change history.
The planet was revealed to be Earth in the past, putting the conflict in a vital context. The two forces soon became embroiled in an "experiment" by the mysterious Vok, and Primal gave his life to stop the destruction of the Maximals by the aliens' Planet Buster. There, he and his Maximal crew scanned beast modes and battled Megatron's criminal band of Predacons in what the Maximal dubbed the " Beast Wars". When he received an alert about a fugitive Predacon ship, the Darksyde, he had the Axalon pursue it through a transwarp portal, eventually ending up on a primitive planet. Optimus Primal was a minor Maximal officer of little note who commanded the Axalon. 3.1.2 Beast Wars: Transformers video game.3.1.1 Beast Wars: Transformers video game advertising comic.3.1 Beast Wars: Transformers video game continuity.1.16.2 War for Cybertron Trilogy cartoon.1.16.1 War for Cybertron Trilogy marketing material.1.16 War for Cybertron Trilogy continuity.1.14.1 Prime Wars Trilogy marketing material.It is possible Optimus Primal is the greatest Cybertronian hero who has ever lived. Optimus Primal is extraordinary for not only being able to distinguish himself, despite living in the shadow of Optimus Prime, but he may even have surpassed the greatest of the Autobots, seeing as he saved the life of his namesake and ushered in a new technorganic Cybertron. This is the only time he is self-absorbed. However, he is so committed to helping others that he can withdraw into a deep depression when he feels he has let them down. ("Sometimes, crazy works", he says.) He is eternally loyal to his friends and respectful to his enemies. He is committed to the Maximal codes of honor and moral judgment, but he does view them with some irreverence, and is not above finding loopholes or administering unorthodox solutions if necessary.
Though he does have a penchant for stuffy speeches, Optimus Primal is much more down-to-Cybertron than his legendary namesake. The rest, they say, is (literally) history. Young and untested, Optimus Primal was a mere captain of an exploration ship when he and his crew were diverted off-course to pursue a stolen Predacon ship under the leadership of some crook named Megatron.
