Encore: #12 Metroplex features robot mode/attack mode, vehicle mode, and base mode. Metroplex is accompanied by robot units Scamper, Slammer, and Six-Gun, and an array of weaponry and accessories including Anti-Matter Projectors, Ion Pulse Rifles, twin guided missile launchers, particle beam pistol, acetylene pistol, maser cannon, mortar cannon, missiles, and fists. It is unknown whether the Encore: #12 Metroplex will feature plastic tires or rubber tires. Bulky and square-framed, Metroplex interacts well with smaller Autobots. Scamper transforms from a black six-wheeled car into a patrol robot. Slammer is derived from one of Metroplex�s towers and the mortar cannon. The aptly-named Six-Gun is derived from a portion of one of Metroplex�s towers, Metroplex�s anti-matter projectors, ion-pulse rifles, and twin guided missile launchers. Comprising at least a substantial portion of the vast Autobot City facility, Metroplex is generally considered to be the key adversary of the monstrous Decepticon Assault Base Trypticon, and will typically---provided that Metroplex is capable of Transforming into his robot mode at the opportune moment---overwhelm Trypticon in battle.
