Asteroid City

Asteroid City is an Autobot base from the Energon portion of the Unicron Trilogy continuity family.

Asteroid City is the name given to a space-based structure designed as an energon mining installation. It also serves as one of many bases in Earth's solar system for the Autobots. It had a space bridge built in to it and also had housing quarters for human and transformer alike, and may have served as the forward observation post for the alliance.

Energon cartoon

Located in the asteroid belt between Mars and Jupiter, Asteroid City was among the targets under attack by Terrorcon raiders early in the Energon conflict. Due to the size of the facility and the ease for Terrorcons to attack, however, it largely became abandoned by the time the Earth's energon grid was installed.

At least one dedicated space station served as part of the facility. Carlos Lopez was stationed there, and often provided the Autobots with advanced warning of attacking Terrorcon or Decepticon forces.
