Earth, originally known as Unicron, is a planet introduced in the 2007 Transformers movie. Throughout history, Earth has attracted many inhabitants of the planet Cybertron, this is because Earth is in fact Unicron, the enemy planet of Cybertron.
History
Billions of years ago, the Earth formed around the inert body of Unicron, the Chaos Bringer. In time, continental drift would break up his physical form; primitive peoples would build Stonehenge over the point where Unicron's horns had once aligned.
Pangaea
Within his crust, Unicron's horns were arranged in the pattern of an octagram with his mouth at the centre.
Prehistory
The Primes build a Star Harvester for harvesting Energon
The Fallen betrayed his brother Primes
The Fallen's servants battled against those of his brother Primes
The Pyramid of Giza is built to conceal the Star Harvester
In 17,000 B.C.E., the Dynasty of Primes came to Earth with their warriors and workers to build a Star Harvester, a machine that drained the power of the sun in order to recharge the AllSpark. Just as they finished the Harvester, the Primes discovered the primitive humans. Most of the Primes upheld their rule of sparing life, but one Prime, forever known as The Fallen, despised the humans as insects and sought to seize the AllSpark's power for himself. A great battle took place, but in the end, the Dynasty of Primes stole the Matrix of Leadership, the key to activating the harvester, and hid it in a tomb made of their bodies. The harvester was abandoned on Earth, in the country that would be called Egypt. The native humans built a pyramid over the device.
Over the years, Decepticons who called themselves the Seekers travelled to Earth in the hopes of finding the Matrix of Leadership. Symbols and pictures of them ended up on ancient human relics; in time, however, the majority ran low on energon and went dormant, entering a protective stasis lock.
The Dark Ages
65 million years ago, a mysterious race known only as the Creators came to Earth, cyberforming swathes of the planet with their specially-engineered Seeds that transmuted everything it touched into elemental metal. The native dinosaurs were caught in the blast radius, resulting in their mass extinction which humans would initially believe to have been the work of an asteroid impact. For unknown reasons—presumably they only wanted to mine the transformium that their Seeds had created—the Creators then left Earth, allowing its organic life to take over once again.
1800s
Second World War
Various Transformers had visited Earth over the years; these included both Bumblebee and Hot Rod, who joined the Allies during World War II.
1960s-1970s
Voyage to the Moon
The Ark, piloted by Sentinel Prime, crash-lands on the Moon
Soundwave and Laserbeak sabotaged the Space Race to conceal the Ark
In 1961, the Ark crashed on Earth's moon, sparking the space race. By 1972, Soundwave and Laserbeak had landed on Earth and coerced humans into helping them end the space race to protect the Ark from discovery. Sector Seven was involved in the American effort to explore the Ark.
2007
The Allspark would crash into Earth
Megatron would be uncovered by Archibald Witwicky
Sector Seven is formed after the discovery of Megatron
Hoover Dam is built to conceal the Allspark
The AllSpark itself crashed onto Earth approximately 10,000 B.C.E., followed a few thousand years later by the Transformer Megatron who would become buried at the Arctic Circle. The inadvertent discovery of the latter by Captain Archibald Witwicky would, eventually, lead to the formation (at ...some point) of the Sector Seven organization, a United States secret service meant to handle "non-biological entities". Hoover Dam would be built as a secret holding base for Sector Seven, near to populous Mission City.
The Decepticons were defeated by the Autobots
The Decepticons' bodies were dumped
By covertly reverse-engineering this advanced Cybertronian technology, human technological development rapidly increased, and by the modern day most electronic technology owed something to Megatron. The United States had thus become so powerful the United States military possessed bases in foreign countries such as Qatar and NASA had total supremacy over space-related matters. Sector Seven had its own paramilitary wing and prisons, all while being so secret the Secretary of Defence was unaware of its existence. The Autobot Bumblebee was sent to Earth to find the AllSpark, and in the summer of 2007 the Decepticons arrived on Earth in search of both the AllSpark and their leader, learning of Archibald Witwicky's glasses, upon which the physical location of the AllSpark was imprinted. Optimus Prime and the Autobots arrived on Earth to secure the AllSpark. Open warfare would result, ending in a final battle with both the military and the Autobots fighting against the Decepticons at Mission City. Sector Seven were decimated and the AllSpark cube destroyed, but the Decepticons were defeated and Megatron killed thanks in part to two youths. Sector Seven was tasked with cleanup, making a brief, if shaky, alliance with the Autobots to escort the remains of the Decepticons for dumping in the Laurentian Abyss, before the organization was shut down for its inept management of the crisis.
2009
NEST worked with the Autobots to hunt down Decepticons
Megatron and the Fallen worked to activate the Star Harvester
New Decepticons landed on Earth and began attacking cities
Optimus Prime defeated both Megatron and the Fallen
By 2009, Barack Obama was the President of the United States, with Theodore Galloway as National Security Advisor and General Morshower as Chairman of the Joint Chiefs of Staff; China was on such good terms with America that it allowed an American dominated international military coalition to operate in its cities, and Egypt and Jordan had established a border with each other. Sector Seven had been replaced by NEST, a joint human-Autobot taskforce that hunted down rogue Decepticons across the globe. That same year, Megatron was revived, and was tasked by his master The Fallen with retrieving Sam Witwicky and killing Optimus Prime. Failing in the former but succeeding in the latter, Megatron decided to escalate the war with the Autobots by making overt attacks, with strikes on Earth cities and the destruction of a major pyramid before the Autobot/NEST team won when Sam Witwicky used the Matrix to revive Optimus Prime, who in turn defeated Megatron and killed The Fallen.
2010-2012
The Autobots discovered the lost Ark and revived Sentinel Prime
The Autobots' resurrection of Sentinel Prime allowed him to activate the Pillars
A few years after the death of the Fallen, the Autobots and Decepticons were public knowledge and energon detectors were set up in all of Earth's major cities to detect Decepticon forces. By this point, the war seemed to be in a peaceful lull as there hadn't been a major Decepticon engagement in a while and the Autobots were helping to deal with humans who were threats to world security, sometimes of their own initiative and against the American government's wishes. After a trip to Chernobyl uncovered an engine part from the Ark, Optimus Prime and Ratchet traveled to the moon and recovered five pillars and Sentinel Prime, who was brought back to life with the Matrix of Leadership.
The Decepticons emerged with an armada from the Moon
The Decepticons invaded Chicago
The Autobots defeated the Decepticons and destroyed the Pillars
This played right into the Decepticons plans as they needed Sentinel to use the space bridge to bring an army to Earth and to bring Cybertron as well, so the Decepticons could conquer Earth and use its resources and human population to rebuild Cybertron. Most of the Decepticon army invaded Chicago, killing countless humans while a few Decepticons spread around the planet to release the space bridge. In Chicago, a massive battle occurred in which a combined force of Autobots and humans assaulted the Decepticon-held city. In the end, Chicago was liberated and the Decepticon army was destroyed along with the space bridge, Sentinel and Cybertron, forcing the Autobots to accept Earth as their new home.
2017-2022
Lockdown and Cemetery Wind hunted down all remaining Transformers
In the modern day, following the battle of Chicago, NEST was succeeded by Cemetery Wind, an extragovernmental authority that used its power to indiscriminately hunt down Autobots and Decepticons alike with the help of the unaligned Cybertronian Lockdown. Though Earth was briefly threatened by the detonation of another Seed, Optimus Prime was able to take it off-planet before it could explode, saving the planet.
The Staff
The Decepticons rallied at Stonehenge, the center of Unicron's mouth
Cybertron began to absorp Unicron's life force through the Staff
Quintessa's plan was thwarted by Optimus Prime and Viviane,
Unicron's horns had risen above the crust. Due to plate tectonics, the original hexagonal arrangement of the horns was lost into randomness, baffling scientists worldwide. It took Seymour Simmons's knowledge of a book in the Library of Trinity College Dublin for Sir Edmund to figure out Earth was Unicron all along and that the strange shape he had seen among many artefacts was in fact Pangaea. This allowed him to find out where the Decepticons would be next; Stonehenge, which was once Unicron's mouth. As Cybertron absorbed Earth's energy, it dragged its massive components across Earth's surface, literally scraping away cities. After Viviane Wembly took back the staff and ended the incident, Quintessa (disguised as a human) travelled the Egyptian desert to one of Unicron's horns. There, she tells the team of scientists there not touch it, as it would incur his wrath Transformers: The Last Knight
