Cybertronian mythology dubbed Metroplex the "First Titan", believed to be the original member of the Titans from the time of the Knights of Cybertron. The Reluctant Specialist Legends claimed that he, Chela and Metrotitan had once fought alongside Primus himself, Origin Myths and he was said to have defeated the monster known as Trypticon and watched as it was sealed away in the depths of Cybertron. The Illusion of Control Salvation After disappearing for some time, the three Titans resurfaced during a battle between the armies of Megatronus and Onyx Prime, rejoining civilization in time for the rise of the Thirteen Primes. Origin Myths Metroplex was approached by Alpha Trion, and together they explored the entire surface of Cybertron. Omega's Conundrum Along with Chela and Caminus, Metroplex presided over the banishment of both Vigilem and his master Liege Maximo during the First Cybertronian Civil War, severing their brother's higher functions and rebranding him as "Carcer" before sending both deceivers adrift in the stars. Metroplex hoped that that would be the end of Vigilem but wondered if he'd been too merciful.
