Autobot City

Autobot City is the home base and primary headquarters of the Autobots.

Overview
Autobot City on Earth is the center of operations for the Autobots, and later the primary base following damage done to the Ark. Large enough to house possibly hundreds of Transformers it had laboratories, communications decks, command centers, and meeting rooms. It also had the ability to transform into a heavily armored fortress capable of holding off a sustained full-force Decepticon attack for over 24 hours. A smaller sub-section of the city could transform into the giant Autobot warrior, Metroplex.

The city's communications tower transforms into Six-Gun. One of the buildings transforms into a tank called Slammer.

Location
Built by Grapple and Wheeljack prior in 1986, Autobot City was originally located near Lookout Mountain, in the Alabama, Georgia, and Tennessee tri-state area.

It has since been moved several times. It is currently located in the Nevada Desert, away from human settlements, where it collects geothermal and solar energy to limit the Autobots' reliance on fossil fuels.

Armaments
When in defense mode, Autobot City is armed with numerous laser cannons, missile launchers and double blast doors to keep Decepticon invaders out.
