Autobot City

Autobot City (also known as Autobot City: Earth) is a city established by the Autobots on Earth, often under the command of Ultra Magnus. As well as being outfitted so that a large number of Autobots can live and work in comfort, the city can transform into a fortress as shields engage and weapons appear all over it. The transformation needs to be triggered by a series of bulky manual operations.

Generally, it is linked to Metroplex in some way, sometimes to the point where "Autobot City" and "Metroplex" are used interchangeably.

Madman The Transformers comic
By the year 2001, the Autobots' presence on Earth was sufficiently established that they began construction of their own high-tech, Transformer-scale city in North America. This work was carried out while the balance of the Autobot forces were engaged in an evacuation operation from the Decepticon-controlled Cybertron. The building site was also the location of a not-so-secret bunker where Optimus Prime stashed the Autobot Matrix of Leadership on the off-chance he should be captured or killed by the Decepticons during the exodus from Cybertron.

The Transformers cartoon
The city was completed sometime before the year 2005 and was a key part of the Autobot war machine (acting as a stronghold and energy storage facility). While Optimus Prime himself commanded from the Autobot moon bases, Ultra Magnus was in charge of the city. Autobot City then took major damage during a Decepticon attack in the same year. Several notable Autobots fell during the battle, and both Optimus Prime and Megatron mortally wounded each other.

Not long after Optimus' death and Ultra Magnus' promotion to Autobot supreme commander, the heavily damaged city was again attacked by the new Decepticon leader Galvatron and his forces. Magnus and a group of Autobots fled into space, drawing the Decepticons away from the still-smoldering city.

The city was fully repaired by 2006 and continued to operate for some time afterwards.

Following the destruction of Autobot Headquarters, Autobot City now under the command of Blaster—became the main Autobot stronghold on Earth. To replace the lost Teletraan I, Autobot City's internal computer was Teletraan II. Metroplex transformed into a section of the city, being able to detach himself and become mobile when needed. Autobot City would occasionally come under attack by Decepticon-hunting Decepticons, deceased Decepticons and was even the target of an overly ambitious human criminal's revenge.

In 2007, the Decepticons launched an attack on Autobot City to steal the Key to the Plasma Energy Chamber. However they did not cause anywhere near the amount damage caused during the 2005 attack on the city.

Scramble City: Mobilization
At some undetermined point in time, Optimus Prime ordered the construction of a massive mobile fortress code-named Scramble City, believing that the Autobots would need a much larger base if they were to defeat the Decepticons. Housed in a gigantic underground facility, numerous Autobots and their human allies (Spike, Carly and Chip among them) worked to complete the behemoth under the leadership of the newly arrived Ultra Magnus.

Unfortunately, Megatron caught wind of some sort of secret project and ordered Soundwave to investigate. While Blaster and his cassettes managed to drive off most of the Decepticon cassettes, Ratbat managed to sneak into the cavern and return with an intelligence report. After receiving the report, Megatron immediately ordered an attack to destroy Scramble City before it was complete.

The initial attack led by Starscream was repelled, so Megatron decided to dispatch a second wave of attackers: the Stunticons! The Stunticons put up a much better showing than the previous attackers, putting the Autobot defenders under heavy pressure and driving Superion to the brink of defeat. The Combaticons also arrived to reinforce the Decepticon attack and quickly forced Superion to flee.

Unfortunately for the Decepticons, the Autobots held them back long enough for Scramble City to become operational. Ultra Magnus dispatched the Protectobots, then transformed Scamble City to mobile station mode and brought it into battle. Transforming into the towering Metroplex, Scramble City then sent the Decepticons packing with a single shot.

Robotmasters
Brave Maximus was integrated into Autobot City as well.

The Headmasters cartoon
By 2011, Autobot City was still the Autobots' Earth-based stronghold, and seemed to be under the command of Ultra Magnus. A space bridge terminal was built into the city, connecting the Earth to similar terminals on Cybertron and Athenia.

The space bridge terminal in Autobot City was ultimately destroyed by Sixshot, causing a chain reaction that destroyed all other space bridge terminals in the network.

While defending Autobot City and the Earth from another attack by Sixshot, Ultra Magnus was killed.

Wings Universe
During the Battle of Autobot City in 2005, Devastator crashed through the walls of Autobot city. Ultra Magnus, Red Alert, Sideswipe, and Tracks counterattacked, blasting Devastator back into his component Constructicons, but the Decepticons gunned down Red Alert and forced the others into retreat. Further behind, Megatron was triumphant at their breach of the city.

Following the Rebirth, Optimus Prime and his Autobots chased Galvatron and Zarak's forces into deep space, leaving behind only a small number of defenders at Autobot City to guard against further Decepticon appearances.

In 2010, several first generation Autobots from Autobot City deployed to assist Pyro's second generation Autobots against Clench's Decepticon Syndicate at the Large Hadron Collider in Switzerland. When the Decepticons looked to be losing, Breakdown tried to shoot the forestonite canisters to blow everyone up. Instead, the forestonite gas leaked and spread, granting powers to all the Transformers present. The Decepticons' advantage lost, Clench called a retreat, and the Autobots were victorious. Afterwards, Streetwise elected to remain with Pyro's forces rather than return to Autobot City, feeling more at home with the Generation 2 Autobots.

In 2012, Autobot City played host to a number of alien ambassadors. Outside, Cliffjumper, not trusting the "new" forestonite powers, had several forestonite-enhanced Autobots demonstrate their powers on dummy Decepticon targets. Meanwhile, Ultra Magnus briefed Pyro's team about a break-in at Quantum Laboratories and assigned them the task of finding the perpetrator. By this point, Autobot City had memorial statues to Windcharger, Huffer, Red Alert, and Wheeljack.

Later, after dealing with Jhiaxus on Qre, Pyro's team returned along with several clones to Autobot City on Earth to inform Magnus of what had transpired. They were then interrupted by Sizzle, whose forestonite-based precognition had just given him a vision of the "Machine Wars".

As the Autobots and Decepticons fought the Cybertronians in the Machine Wars in 2013, Obsidian utilized the Sandstorm clone to send a signal via a serro-gyro mekarach to Earth. Receiving the signal in Autobot City, Pyro then deployed Alpha Team, led by Rapido, and Bravo Team, led by Serpentor, through a space bridge to reinforce the united Autobot-Decepticon forces on Cybertron.

One week later, Autobot City was host to the signing of the Pax Cybertronia among the Autobots, Decepticons, and Jhiaxus's clones.

Marvel The Transformers comics
The plans for Autobot City: Earth were finalized in 2003. Both the Autobots and the governments of Earth had hands in its construction. It was completed and opened in 2004, likely on the same site that Galvatron had built a superweapon to destroy Unicron in 1986 (putting it in or near Oregon). Despite interference from Shockwave, the city opened on schedule, and relations between Autobots and humans were strengthened.

It was attacked by the Quintessons in 2008, leaving many Autobots severely wounded and the city in terrible shape. The Quintessons were only driven off when Hot Rod activated the Transformer that made up the city's sentient core, Metroplex (the city needed a Transformer within it to be able to transform itself). While successful, Metroplex's emergence only damaged the city further, and it was still in a state of disrepair the following year.

In the revised timeline following the Time Wars, the Autobots fled there in 2009 to escape a Decepticon-dominated Cybertron. They had long since reclaimed the planet by 2356; then, Autobot City was providing medical care for a decrepit Rodimus Prime, who was possessed by Unicron.

Battle Beneath the Ice
When the scientists of CalTech caught wind of a drilling team discovering a futuristic city beneath the ice of the Erebus oil field, they contacted Autobot City. The Autobots responded, and dispatch Slingshot, Skydive, and Hot Rod to help with the ensuing investigation.

Big Looker storybooks
At work at Autobot City, Kup and Hot Rod heard on the radio about the unveiling of a voice-controlled robot car at the coliseum. Leaving their tasks behind, the two went to attend the event. However, their talk about the robot car was overheard by Soundwave, who relayed it to Galvatron. Galvatron had been looking for a suitable worker to build him a city akin to the Autobot City, Decepticon City, and believed the robot car to be the ideal option.

The Decepticons set out to steal the robot car, but Kup and Hot Rod spotted them at the coliseum. Kup ordered Hot Rod to return to Autobot City and warn their comrades while he'd keep an eye on the Decepticons. Hot Rod raced back and explained the situation to Ultra Magnus, who immediately had the Autobots transform and roll out to stop whatever the Decepticons were planning to do.
