The most vast and mighty Autobot ever created, Metroplex is a member of a race long thought of as nothing more than legend. He is impossibly ancient, brought online in a time before the long memory of his Autobot comrades even began. He is a living artifact of an era when Cybertron was united, and needed defenders only against hostile outsiders. It is his memory of that peaceful past that drives him to fight for the Autobots. It is hope for the return of peace that motivates him to crush every Decepticon he can see beneath his mighty feet.
