Armed City


 * Armed City is (or isn't) a Cybertronian base from the Energon portion of the Unicron Trilogy.

After the Unicron Battles, the Autobots and their human allies created many Cybertronian bases on Earth and elsewhere. One of them was known as Armed City; it apparently had been a particularly large and/or difficult construction project.

As the humans and Autobots scrambled to create a system of energon towers to defend Earth from Megatron's attacks, Kicker noted that the work was the largest construction project he'd seen since Armed City was built.
