Metroplex is the colossal Autobot City Guardian, capable of transforming into an enormous city complex and a powerful battle station. First appearing in Transformers G1 Season 3, Episode 4: “Five Faces of Darkness, Part 4,” Metroplex serves as Cybertron’s towering protector—a living fortress who embodies the Autobots’ resilience, firepower, and strategic might. His ongoing rivalry with the Decepticon titan Trypticon defines some of the most spectacular battles in the G1 cartoon.
Origin and Role in the G1 Storyline
Metroplex originates from the Autobots’ efforts to gain a technological advantage in the post-movie era. After the destruction of Autobot City on Earth, the Autobots develop a new defense strategy: titanic transforming cities capable of autonomous combat. Metroplex becomes the crown jewel of this initiative.
In the G1 cartoon, Metroplex is portrayed as:
- Autobot City come to life – A living base capable of independent thought.
- The Autobots’ central fortress in the post-Unicron era.
- A Titan-class warrior, able to transform from city to battle station to giant robot.
- A strategic equalizer against overwhelming Decepticon threats.
He often deploys smaller partner robots such as Six-Gun, Slammer, and Scamper, all of whom assist in defending Autobot City. Metroplex’s primary role is to safeguard Autobot operations on Cybertron and Earth, acting as a stabilizing force during escalating Decepticon attackssette characters.
“Metroplex heeds the call of the Autobots!”
