Megatronus Prime is reincarnated a year after the events of Transformers One, along with the other Primes.

Long before the war... long before the Primes... long before Cybertron as you know it, there was The One. From its spark came creation...and destruction. Unicron rose to devour the universe, Primus fought back, and a cosmic game of cat and mouse began that would shape reality itself. The Thirteen Primes were born to guard their slumbering father, while love, betrayal, and ambition festered among the first of their kind. Quintessons were forged, Titans sailed the stars, and the Requiem Blaster was wielded...all while the first legends of Cybertron carved a path that would echo for eons. Witness the secret history of gods, monsters, and the spark that started it all. This is the story before stories, the war before wars, the dawn of everything. Part of the Transformers Readimatic Universe. DISCLAIMER: I do not own the Transformers franchise. Rights to Transformers go to Hasbro, Takara Tomy, and Paramount.
