Metro Paul (メトロポール), more commonly known as Metroplex (メトロプレックス) is a gigantic robot whose alternate mode is a city. A more than capable arsenal in the Gekko Family ranks, Metropaul doesn't care for his own safety and is more than willing to sacrifice anything if it means securing the victory for his fellow comrades in the war. He has tremendous power, is loaded with rockets and isn't afraid to crush Decepticon leaders with his fist. In other words, don't piss him off. It's home Planet was Dens

Metro Paul had been lying dormant in what would become Izumo City and Shinto the Treasure Planet, where Shinto Flint buried a vast enormous treasure in the center chamber for thousands of years, and inadvertently became a part of the battlefield when Kuro Akatsuki declared War. After pulling a switch or two, Paul Gekko observed the interior of Metropaul and where his Ancestor was found constantly shifting and transforming to accommodate him. After using a turret to help fight the Akatsuki, Paul found himself herded to a mysterious bright light by the shifting interior. Sensing a Cybertronian presence, Paul desperately ordered the entity to help the Autobots and the Hylian Federation in their time of need. After a final switch, an entire city began to transform into an immense, powerful Autobot—Metroplex, who had heeded the call of the Last Prime (Paul Gekko). Metroplex's presence on the battlefield proved invaluable to the struggling Hylians. The titan easily wiped out much of the Kuro Akatsuki army, including the deadliest of foes such as Marauders. Metroplex would launch a devastating air strike on whatever target Paul marked for destruction, and the colossus was able to wipe out Cloud's equally massive guns that were giving the White Angel a hard time. Days later, after the Battle of Ka Boa Bu, the Hylians located another source of Chakra, which is Earth, Metropaul offered to sacrifice his life, donating the energon inside him to give the White Angel enough juice to launch. Paul Gekko protested, but Metro Paul had made his choice. Connecting his Spark to the White Angel's fuel tanks, there was enough energon to launch the ship to the Warp Hole. The heroic titan collapsed for a final time, but was happy to see the Gekko Family, Renato Clan and the Shimiza Clan finally leaving Planet Dens, and in his dying moments, Metropaul's last words were, "'Til all are one." Paul Gekko sadly swore that Metro Paul's sacrifice would not be in vain.
