"Metroplex heeds the call of the last Prime."
―After Metroplex was summoned by Optimus Prime
"Metroplex, you must destroy the Decepticon Warp Cannons on the outskirts of the city!"
―Optimus Prime ordered Metroplex

Metroplex is a gigantic Autobot titan whose Alt-Mode is a huge city. He is equipped with giant shoulder and back cannons, raining artillery down on Decepticons stupid enough to face him.


The exact circumstances of Metroplex's creation are unknown, but given that he answers to Optimus Prime alone, it is believed the Primes created him out of their city. Eventually he ended up in stasis lock where Iacon would be built, unknowingly becoming its center.

Fall of CybertronEdit

During the Decepticon attack on the Ark, Metroplex remained dormant until, in desperate times, Optimus Prime summoned him to fend off the invasion, which was very successful and destroyed Megatron with his huge fist.

Later, he sacrificed his remaining energon supply into the Ark so that the Autobots can leave Cybertron. His last words are: "Till all are one". Optimus vowed that his sacrifice will not be in vain as the Cybertronian giant collapses.

Alpha Trion later noted that any energy that was not needed for the Ark was not enough to power Metroplex, so he sent all his remaining spark energy down to Primus taking a few thousand years off the reboot time.

Personality and TraitsEdit

Metroplex has shown undying loyalty to Optimus Prime and a love for Cybertron. Despite this compassionate traits, he is shown to have an extremely short temper, smashing several Decepticons, whose firepower could not affect him and murdering Megatron for one shot to the chest.

Behind the ScenesEdit

  • Metroplex first appeared in the G1 cartoon as a city in Transformers:The Movie & as a robot in The Five Faces of Darkness mini-series. Oddly for an '80s cartoon, he was euthanized to prevent him from being infected by the Hate Plague. While he firmly established as an artificially created life-form in that continuity, his origins are left ambiguous in the Aligned continuity family.


  • Metroplex is technically the largest playable character in Fall of Cybertron video game. Bruticus is a distant second and Grimlock close behind.
