Metroplex
A walking fortress of steel and light guarding the weak across his wide streets.
Metroplex is one of the biggest Transformers in existence, shifting into a fully functioning city instead of a vehicle or weapon. Loyal to the Autobots, he works as a mobile fortress and sanctuary that shelters allies while blocking enemy forces during space wars. His form mixes architecture with sentience, showing Cybertronian engineering where defense and living space meet. Whether sitting still on Earth or fighting in deep space, Metroplex houses thousands inside his body and takes hits that would crush regular cities.

Lore & Background
In the original continuity, Metroplex was an ancient construct designed to serve as a refuge during times of great peril. He remained dormant for eons until the conflict between Autobots and Decepticons reached Earth, where Optimus Prime and his team discovered him buried beneath the surface. Upon activation, he rose from the ground to become a strategic stronghold, transforming the battlefield into a mobile base that could withstand heavy bombardment. His internal systems function independently, maintaining power grids and life support for the Transformers residing within his city mode. This unique capability allows smaller units to operate safely inside him while he engages in combat on an external scale. His presence often turns the tide of war, as enemies struggle to breach defenses that are literally built into a living god-machine.
In Their Own Story
The ground trembled beneath Optimus Prime's feet as the ancient sequence completed. Dust swirled around the massive silhouette emerging from the earth, steel plates shifting with the sound of grinding tectonic plates. Lights flickered on in windows that were once dormant rock, illuminating a cityscape rising into the twilight sky. Metroplex opened his eyes, glowing blue against the dark horizon. "I am ready," he rumbled, his voice vibrating through the chassis of every Autobot standing within his streets. The war had come to Earth, but now, they had a home that could fight back.
Reader's Guide
Metroplex functions as a mobile habitat, his internal geography mimicking a dense urban sprawl complete with plazas, transit hubs, and defensive perimeters. The exterior plating resembles skyscrapers in city mode, while robot mode reveals towering limbs capable of planetary-scale interaction. Technological levels are ancient yet adaptive, integrating Cybertronian energy grids with organic-like maintenance systems to sustain life within his chassis. Key landmarks include the central command spire and the outer gateways used for troop deployment. Historically significant as a refuge during the Great War, his presence shifts the battlefield dynamics entirely. Climate control is internal, shielding inhabitants from external atmospheric hazards on hostile worlds like Earth or Cybertron. His existence bridges architecture and warfare, proving that defense can be built into the very ground troops stand upon. The streets inside function as pressurized corridors for smaller Autobots to maneuver safely during siege conditions.
