In the Anteverse, the Precursors created a rift at the bottom of the Pacific Ocean on August 13, 2013 (a.k.a. K-DAY) were they began their assault on Earth by sending an Trespasser Kaiju to attack San Francisco and destroyed the Golden Gate Bridge. The Kaiju destroyed much of the city and managed to reach the neighboring cities of Sacramento and Oakland. It was later killed by three nuclear missiles after all other attempts at stopping the Kaiju proved futile. Six months later, another Kaiju attacks the city of Manila in the Philippines and was killed in a similar way to the previous Kaiju. Another Kaiju attacked Cabo San Lucas in Mexico and was later taken down. Months later, another Kaiju appears and attacks Sydney, Australia that was destroyed three days later by the military by luring it away from the city and killing it with a nuclear bomb. It was later discovered that the bioluminescent blood that Kaiju possesses can cause a toxic phenomena to Earth's ecological stability called "Kaiju Blue" when massive amounts of it is secretted into the oceans. By then, it became clear that the chronic Kaiju attacks weren't going to stop and that humanity had to do something to end the death and destruction caused by the Kaiju. A conference meeting was held in Seoul, South Korea on September 15, 2014 where the ruling powers of the world discussed what should be done to end the reoccurring attacks. At the meeting, a man named Dr. Jasper Schoenfeld purposed the idea of using an alternative measure to killing the Kaiju without nuking a country in the process, that alternative measure being the use of giant, human piloted mech suits called "Jaegers". Coastal trading and boat travel stopped as sea ports began to become shut down to prevent any further casualties. This ultimately causes Earth's economies to plummet and led to riots in the streets of various coastal towns and cities. With all the chaos engulfing the populace of the world, the nations of the world decided to put aside their petty differences and set up the Pan Pacific Defense Corps. to monitor the breach and any Kaiju activity, as well as initiate the Jaeger Program. As testing for the Jaeger Program began to go into affect, the use of neural control became the prefered use of piloting the Jaegers. However, it was discovered that controlling a giant mech such as a Jaeger was too much for a single human mind to operate and attempting to do so can result in fatal brain damage. It was decided that the preferable method of pilotting a Jaeger were to have two pilots control the left and right hemisphere of the mech, which would result in the two pilots thoughts and memories being open to each other. From 2018-2019, a brighter future began to be made for humanity as the Jaeger Program proved to be a success in stopping the hoards of Kaiju coming through the rifts. Life began to return to normal for society and the Kaijus and Jaegers began to be marketed in the form of toys and cartoons and retired Jaeger pilots became rock stars. Over time, a religion based around the Kaiju began to form with converts believing that the Kaijus came from Heaven and that they were the result of God punishing humanity for it's sins. Later from 2020-2024, much more higher level Kaiju began to emerge from the rift and began to destroy some of the Pan Pacific Dfense Corps. most powerful Jaegers against the Kaiju and hope began to return to a bleak stake. In 2025, the Pan Pacific Defense Corps. began to look for other alternative measures to preventing any further casualties such as the Shatterdome in Sydney, Australia, which was a massive wall build to prevent Kaiju from entering the city. Although, this proved to be ineffective as a level IV Kaiju tore through the Shatterdome with little effort. Later further studies on the rift were made and the Pan Pacific Defense Corps. discovered how the rift can recognize what enters and exits the rift and will not allow anything that doesn't possess Kaiju DNA to cross over. With how the PPDC realized that they can't keep standing their ground forever, they are forced to stop the Kaiju invasion at it source and end it for good. A mission was put in place to have the pilots of the Jaegers known as Gypsy Danger and Striker Eureka venture down into the rift and using nuclear reactors to severe the connection between Earth and the Anteverse. After fighting off three separate Kaiju under water and the deaths of the Striker Eureka pilots, the pilots of Gypsy Danger used a Kaiju carcass to enter the rift. As Gypsy Danger fell through the rift, the two pilots primed the nuclear reactor for detonation and managed to escape before the explosion. the rift was ultimately destroyed and the war had ended.
