5. Metroplex
Hasbro/TakaraSometimes, Metroplex is a city. Sometimes, hes a base for combat operations. Sometimes, hes a mobile battle fortress. Sometimes, his size even ranges from sheer ginormity to simply being a tad taller than car transporter Ultra Magnus. But hes always an absolute beast of a Transformer, one of the Autobots greatest weapons. Lets go with the thought of Metroplex being a city. Now imagine if that appeared in a future Transformers film a Transformer disguising itself as a city. An entire city. Much like that other giant city Autobot Fortress Maximus (hes not on this list as number 5 was reserved for either, not both), Metroplex would scupper any combiner the Decepticons could throw at our heroes.
