Pacific Rim

The neural link is what allows two or three pilots to pilot the Jaeger. The pilots don their flight suits and climb into the Jaeger's head, which also serves as the cockpit. They stand on the piloting platforms, and upon putting on their helmets and activating the link, the pilots share thoughts, memories, emotions, pain, and feelings, becoming completely connected to share the neural burden of piloting a Jaeger. If one of the pilots becomes stuck in a memory, it can be dangerous and even damage their brain; therefore, both pilots must let go of memories and form a strong link to be able to pilot.

Raleigh and Yancy Becket piloted the Gipsy Danger (Mark-3) in 2020, where Yancy died in combat; later, Raleigh Becket and Mako Mori piloted the same Jaeger in 2025 to close the Breach.

Aleksis and Sasha Kaidonovsky piloted the Cherno Alpha (Mark-1) in Russia from 2015 until its destruction in 2025; they were the first to demonstrate the neural connection (Drift) in combat.

Herc and Chuck Hansen piloted the Striker Eureka (Mark-5) in 2019, achieving the highest kill rate; in 2025, Stacker Pentecost replaced Herc for the Jaeger's final self-destruction.

The Wei triplets (Cheung, Jin, Hu) piloted the Crimson Typhoon (Mark-4) from 2018, being the first Jaeger with three pilots and specializing in speed and three-arm coordination.

Amara Namani piloted the Bracer Phoenix (Mark-5) from 2025 and then the Gipsy Avenger (Mark-6) in 2034, being a prodigy pilot who also built her own Jaeger, the Scrapper.

Meilin Gao and Ryiochi piloted the Saber Athena (Mark-7) in 2033, the most advanced and acrobatic Jaeger of its time.

Adam Casey piloted the Brawler Yukon (Mark-1 Prototype) in 2015, being the first Jaeger in real combat against the Kaiju Karloff, before being destroyed by an unknown Kaiju.

Duc and Kaori Jessop piloted the Tacit Ronin (Mark-1) in Japan from 2015, known for their deep and tragic neural connection, destroyed in 2022 after massive damage.

Stacker Pentecost and Tamsin Sevier (later Gunnar and Vic Tunari) piloted the Coyote Tango (Mark-1) in Japan, retired due to damage and reintroduced until its destruction in 2022.

The Jaegers are tall, humanoid robots. Over the years, their designs changed considerably, incorporating large firearms or bladed weapons, but they never strayed far from their human-like design, except when they had more than two limbs on their torso. They were highly complex mechanical robots; some were crude with high attack power, others faster but less durable, and still others more balanced.

The APEX Jaeger Pilot Academy is the world's largest international academy. Capable of housing up to 100 million cadets, it is headquartered on a floating island larger than many countries combined. The island houses hangars displaying both new and old-generation Jaegers as museum exhibits, combat training and education centers, engineering centers for aspiring Jaeger engineers, recreational facilities, sports centers, and residential areas with enormous skyscrapers to accommodate all its cadets. It also boasts both public and private transportation systems. All facilities are built with the latest technology, and everything is meticulously maintained with green spaces and absolute order, under both private and public security. Millions of instructors teach cadet classes that can reach up to 200 students. However, over the years, many leave the Academy due to the demanding nature of the program or because they are unable to meet the expectations and succumb to the pressure.

The starting age for the Academy is 8 years old, ensuring that cadets receive a proper education from a young age. You could enter the Academy at the age of 18, but cadets generally graduated between 20 and 22 because most didn't complete their studies on time, though they still became formidable pilots, soldiers, strategists, or engineers.

During the Kaiju War, the Defense Corps promoted its cause, seeking public support through propaganda. They provided those who volunteered for their cause with jobs in Jaeger construction and the opportunity to enlist in the Jaeger Academy.

The Defense Corps also advocated rationing for the Pacific population to maintain financial stability. Promotional methods included encouraging Rangers to make public appearances, elevating them to global celebrity status. The mass marketing of Kaiju and Jaegers through action figures and apparel served as a boon for the Defense Corps, while simultaneously trivializing their circumstances.

For the next ten years, the Jaeger Program would reach a seemingly permanent state of success and victory against the Kaiju. However, they would cease production of Jaegers in 2019 with the Mark-5 series.

After the first four Kaiju attacks in San Francisco, Manila, Cape Town, and Sydney, a conference was convened in Seoul, South Korea, on September 15, 2014. The meeting gave Dr. Jasper Schoenfeld the opportunity to present his idea for the Jaegers, which led the United Nations to put aside their differences and work together.

The Pan Pacific Defense Corps was founded sometime in late 2014. The organization would act as the primary beneficiary of the United Nations, which would fund Schoenfeld and Dr. Caitlin Lightcap's efforts to create the first six Jaegers with the Jaeger Program.

Although they would have problems properly implementing the Pons Systems and calculating the manpower required to pilot a Jaeger, they would eventually succeed, prompting the Defense Corps to offer its continued support to the program. Once the construction of the Jaegers was authorized, each Jaeger brand was built annually. Their explicit purpose was the defense of various countries and cities along the Pacific Ocean coast from Kaiju attacks.

The following year, on November 25, 2015, the first of more than eight Shatterdomes and the headquarters of the Pan Pacific Defence Corps was established in Hong Kong, China. Within the Shatterdome, Strike Groups are assigned to defend the coastline of their city or country with three or more Jaeger teams.

The Pan Pacific Defense Corps (abbreviated PPDC) is a United Nations-created organization. The Defense Corps represents an international alliance of twenty-one countries throughout the Pacific Rim, united by the shared goal of containing, combating, and eliminating Kaiju.

Deployed and built in Shatterdomes, the Jaegers are operated and maintained by dedicated teams assigned to each robot. Mission control is managed by LOCCENT, and a designated controller oversees LOCCENT's various operations and deployments.

The Jaegers are controlled by two, or rarely three, pilots stationed inside the Conn-Pod. The pilots are equipped with a type of specialized armor that allows them to interact simultaneously with the machine. The pilots' minds are linked in a neural bridge that allows them to control every movement of the machine.

As an alternative to nuclear weaponry, the Jaegers were designed to generate as much kinetic energy as tactical munitions. They were built to match the estimated scale of Kaiju and minimize the damage caused by conventional weapons. However, given the toxic nature of Kaiju, the Jaegers were required to rely on melee combat and short-range weapons, such as swords or other blade-like weapons. Along with melee combat, heat-based weapons like the Plasma Cannon minimize the spread of Kaiju Blue, as they can wound and cauterize the creatures simultaneously.

In order to avoid damage to major cities, Jaegers are often deployed from their respective Shatterdomes in the ports or oceans near the cities surrounding the Pacific coast. Although they are at a disadvantage in the water, the Jaeger's priority is to prevent Kaiju from crossing the ten-mile line, the final perimeter a few miles offshore. If a Kaiju evades a Jaeger and crosses the ten-mile line, preventing it from reaching land becomes difficult.

As such, the inevitable combat that occurs within populated cities creates equal, if not greater, damage to the surrounding environment. Combat with a Kaiju is estimated to last two hours or more. Whether this is a determining factor in the pilot's skill or strength is undetermined.

The "Mark" designation assigned to each Jaeger refers to its release schedule. The production program was divided into five annual deployments, beginning in 2015 and ending in 2019. Six Mark-1 Jaegers were deployed in 2015, followed by Mark-2 Jaegers in 2016 and Mark-3 Jaegers in 2017. The Mark-4 and Mark-5 Jaegers were the last to be produced, in 2018 and 2019, respectively. Jaegers do not have a standardized design template; body types vary widely within each "Mark." This level of diversity among Jaeger designs and weaponry was a tactical response to the high variability in Kaiju forms.

All Mark-1 through Mark-3 Jaegers used nuclear reactors, which put their pilots at substantial risk of developing cancer. Gipsy Danger and Cherno Alpha were the last active nuclear-powered Jaegers to play a role in the ongoing defense of Hong Kong and in the mission to assault the Breach. Mark-4 and Mark-5 Jaegers, however, used digital technology, minimizing the dangers to pilots inside the Conn-Pod.

Unfortunately, developing the Jaeger program was not cheap. It was reported that the cost of building the Mark-5 Jaeger Striker Eureka exceeded one hundred billion dollars, more than ten times the cost of a nuclear-powered aircraft carrier.

Over time, the Jaegers increased their technology and the Mark label came to refer to the level of firepower and combat capability of a Jaeger; currently, the Jaegers have reached the "Mark 15" label.

The Jaeger Program was first developed by Dr. Lars Gottlieb shortly after Jasper Schoenfeld proposed the idea of ​​the Jaeger at the 2014 conference in Seoul, South Korea, following the fourth Kaiju attack in Sydney, Australia, in September.

Before the conference, Schoenfeld sought a more efficient way to kill the monsters without using nuclear weapons. Watching his son play with a toy robot and a toy monster in his room, he found inspiration for giant humanoid mechs that could confront the Kaiju without resorting to nuclear weapons. Dr. Jasper Schoenfeld's idea was approved by the United Nations.

With the help of Caitlin Lightcap, a brain-machine interface expert, Schoenfeld received funding to begin construction of the first Jaeger prototype in a Pittsburgh warehouse. However, the production cost made the Pan Pacific Defense Corps hesitant to continue funding Schoenfeld and Lightcap. Nevertheless, Stacker Pentecost's assistance in testing the effectiveness of the Pons System convinced the Defense Corps to give the scientists greater support than before.

Although the construction of the first Mark-1 Jaeger Brawler Yukon prototype was successful, the drawbacks related to the neural interface, which overloaded the mind of its test pilot, called into question the viability of the Jaeger Program. Lightcap's risky decision to bridge the mind of the next test pilot, Sergio D'Onofrio, created a connection between the two based on technology developed by DARPA, allowing them to simultaneously and successfully pilot the Jaeger. Pleased with the results, the Defense Corps greenlit the production of more Mark-1 Jaegers, which were then deployed to specific countries in the Pacific to intercept Kaiju attacks.

Kaiju are categorized using Roman numerals. The categories are: Category I (one), Category II (two), Category III (three), Category IV (four), and Category V (five). Since 2025, two Category VI (six) Kaiju and one Category VII (seven) Kaiju have been recorded, the latter causing the most destruction nationwide. Kaiju are classified into categories based on factors such as size and destructive capabilities.

Behavior
Science-K officials speculated that the Kaiju are attracted to cities, blocking population centers by following urban runoff.

Kaiju are highly aggressive creatures, especially in combat. However, they are neither clumsy nor do they possess limited intelligence. Working through a hive mind system, Kaiju can communicate instantaneously. This is similar to how pilots communicate in the Link. Their ability to fight and attack in packs is demonstrated in their battle against the four remaining Jaegers: Gipsy Danger, Striker Eureka, Cherno Alpha, and Crimson Typhoon.

Even during one-on-one combat encounters involving a single Jaeger and a Kaiju, the creatures were able to demonstrate a degree of cunning and intelligence. This was first shown during the duel between Gipsy Danger and Knifehead, during which the latter feigned death until its opponent moved away, at which point it tore apart the Jaeger, critically damaging it and killing one of the pilots.

Using their superior strength and intelligence, Leatherback and Otachi are able to coordinate attacks against the Jaegers. Leatherback and Otachi tear apart and crush Cherno Alpha, while Crimson Typhoon is immediately eliminated by Otachi's tail as it destroys the Conn-Pod containing its pilots. Their role as weapons against the Jaegers is further exemplified when Leatherback uses his organic electromagnetic pulse organ to disable Striker Eureka. Near the Breach, while Slattern engages Striker Eureka, Gipsy Danger is unexpectedly attacked by Scunner and Raiju, demonstrating that the Kaiju are capable of planning and executing complex combat and ambush strategies.

During the course of the war, the Precursors enhanced the Kaiju, each one becoming larger and more powerful than the last. Later specimens, such as Otachi and Leatherback, possessed unique biological weaponry, including acid and electromagnetic discharges, in addition to the size, strength, claws, and teeth of the standard Kaiju.

Although their bodies decompose rapidly, Kaiju organ harvesters are always quick to collect Kaiju parts for their own use and sell on the black market. According to Hannibal Chau, every part of a Kaiju is usable; even Kaiju excrement has a practical purpose.

Kaiju are colossal in size, averaging hundreds of feet in height and thousands of tons in weight. Due to their enormous body mass, two brains are required to control a Kaiju's motor and cognitive functions. Bipedal Kaiju tend to possess multiple arms (usually two main arms and a smaller pair); the ulna and humerus are visible and slightly extended, making it appear as if there are two forearms.

Their bodies allow them to adapt and dominate both land and water once they enter Earth through the breach. Kaiju can breathe and survive in multiple environments, including land, underground in extreme heat and pressure, underwater, and even in airless places like space. As biological weapons, their anatomy is designed to be extremely useful tactically.

Kaiju are also symbiotic, as they possess large parasitic organisms attached to their bodies.

Kaiju tissue is cloned from a single DNA sequence by the Precursors, who "build" Kaiju by fusing tendons from body parts of other Kaiju creations. All Kaiju share the same genotype but have highly varied phenotypes. This results in anatomical similarities to other types of Kaiju as a consequence of cloning. Once created, the Kaiju are pitted against each other. This process initially selected the most ruthless in close-quarters combat. The surviving creations are then used as biological weapons to rid a chosen planet of its life forms so that it can be colonized. Despite their nature as clones, each individual Kaiju is a unique specimen, distinct from the rest of its brethren, resulting in highly varied forms and characteristics.

Kaiju are highly toxic creatures categorized on the Serizawa Scale. Each Kaiju falls into one of five categories. Categories I and II represent the weakest Kaiju, while Categories III through V are the strongest. The Serizawa Scale measures water displacement, toxicity, and ambient radiation levels emitted by their bodies when they cross the Breach. A Kaiju's bodily fluid is ammonia-based. If they die in battle, their bodies activate to immediately self-destruct.

As they decompose, their bodies release a noxious agent into the air known as Kaiju Blue, their blood. Kaiju Blue has the ability to contaminate the air and its immediate surroundings, rendering them essentially uninhabitable. A Kaiju's blood is highly acidic and corrodes everything in its path. This makes it especially difficult to safely collect samples for examination and experimentation. As a result, the Jaegers have been equipped with weapons that cauterize the wounds they inflict on Kaiju to prevent the spread of their highly acidic internal fluids. As silicon-based organisms, the design of their bodies makes it difficult to identify and study particular parts of their internal systems.

2024-2025
In 2024 alone, there were thirteen Kaiju attacks, resulting in staggering Jaeger losses. Hermann Gottlieb speculated after the Sydney attack that the increasing frequency of Kaiju attacks suggested they would appear with increasing frequency until Kaiju could be seen every 8 hours, with that frequency increasing until they appeared every 4 minutes, and double and triple events could be witnessed.

Gottlieb's fears were later confirmed when his colleague, Newton Geiszler, "linked" with a fragment of a Kaiju's secondary brain to obtain information in the K Science Lab. Newton learned that the first wave of Kaiju sent through the Abyss was intended to test and weaken the limits of humanity's defenses. The second wave of Kaiju would have adapted to humanity's battle strategies and would proceed to wipe it out in a mass extinction event.

Leatherback and Otachi simultaneously attacked Hong Kong in search of Newton and, in the process, destroyed two of the four remaining Jaegers, Cherno Alpha and Crimson Typhoon. The Triple Event occurred later during the mission to bombard the portal. Scunner, Raiju, and Slattern emerged from the Abyss to defend their masters from certain destruction at the hands of Striker Eureka and Gipsy Danger. The Kaiju and their masters, within the confines of the portal, were destroyed when Gipsy Danger's nuclear reactor self-destructed. The destruction of the Abyss ended the Kaiju War and destroyed the Kaiju Cloning facility.

2016-2023
Numerous Kaiju attacked various cities across the Pacific Rim and were met with staunch resistance from the Jaegers of the Pan Pacific Defense Corps. Over the next five years, the Kaiju slowly adapted to the Jaegers' forces. However, the Defense Corps believed that the invading creatures were losing to humanity's combined efforts.

They were unaware that the Kaiju's specific reason for attacking large cities and towns was to cleanse the environment of "vermin"; in this case, humanity. While the first wave of Kaiju were simply scouts, the second wave are the Terminators who would finish the job. The information provided by the Jaegers' battles allowed the Precursors to create Kaiju with specific abilities or strengths in a series of "waves." In accordance with their increasing size and strength, the Defense Corps created a "Category" scale, ranking Kaiju on the basis of their toxicity and water displacement.

By 2020, Category III and IV Kaiju were becoming common Kaiju to attack humanity. February 2020 marked the beginning of the Defense Corps' downfall in the Kaiju war when the Category III Kaiju, Knifehead exhibited a learning curve that allowed it to critically damage the Mark-3 Jaeger, Gipsy Danger and kill one of its pilots.

As the Kaiju began to outnumber the Jaegers, the United Nations put plans into motion to create a Wall that would isolate the Pacific Rim from the rest of the world in hopes that it would stop the spread of the Kaiju and begin moving civilians inland from the coasts.

2014-2015
Initially, Trespasser's attacks on the three California cities were believed to be an isolated event. But then, six months later, Hundun appeared and assaulted the Philippine capital of Manila. Four more months passed before Kaiceph made landfall in Cabo San Lucas and caused substantial destruction. As the Kaiju began appearing with increasing frequency, nothing short of nuclear options proved capable of stopping them.

Then Scissure attacked Sydney on September 2, 2014. As Scissure approached the city, the Australian military lured it out and deployed a nuclear missile against it. The attack failed, and the creature advanced into the city and began to raze it. After three days, the military again lured the creature out of the city, hoping to deploy another nuclear missile against it while sparing the city from the effects of radioactive fallout. The nuclear missile was deployed, but although it killed the beast, half the city was destroyed by the blast.

It was clear that the continued use of nuclear weapons was extremely dangerous; the environmental devastation came at too high a price. Therefore, after the attack on Sydney, Dr. Jasper Schoenfeld began to consider how to protect the population without resorting to nuclear weapons. Inspired by his son's robot and monster action figures, Schoenfeld and Caitlin Lightcap managed to create a prototype that would lead to the full production of the Jaegers.

2013
The Kaiju first appeared on August 10, 2013, in San Francisco. The incident is believed to have begun with a 7.1 magnitude earthquake; however, a massive, 300-foot-tall creature, later known as Trespasser, eventually emerged from San Francisco Bay and attacked the Golden Gate Bridge. After destroying the bridge, the creature moved into San Francisco and caused significant devastation, carving a three-mile-wide path of destruction through the city. The enormous creature then went on a 35-mile rampage up the West Coast that lasted six days. It continued as far as Sacramento and Oakland, causing massive destruction in its wake. The U.S. and British militaries responded to the attack and battled the creature for six long days.

Despite the use of troops, tanks, artillery, and aircraft, the combined forces of the two armies failed to kill the enormous beast. On August 15, the military decided to use tactical nuclear missiles in the hopes of bringing the creature down. They finally succeeded in killing it after three tactical nuclear missile strikes. In the aftermath of the destruction, three cities were devastated, and tens of thousands of people died. The dead were mourned, the event was commemorated, and humanity moved on. The incident in San Francisco later became known as Day K.

The Kaiju (怪獣kaijū, Strange Beast) are a race of amphibious creatures generically designed by the Precursors.

They are a race from the Precursor. In 2013, the Precursors opened a portal between dimensions at the bottom of the Pacific Ocean, allowing the Kaiju to enter Earth's dimension. As biological weapons of war, the Kaiju are extremely hostile and toxic creatures designed to wipe out all of humanity.

Triassic Period
During the Triassic period, the Precursors attempted to colonize Earth, but the environment proved uninhabitable and prevented them from surviving on the planet. Therefore, they waited and waited until Earth's environment was ready for colonization.

Creation of the Abyss
The progressive pollution of Earth's environment by humanity allowed the Precursors to survive on the planet and colonize it. In response, they created a race of amphibious creatures, biological weapons later known as Kaiju to humans. Shortly afterward, the Precursors created a portal linking their universe to Earth in the Mariana Trench.

Following the success of the Pons, Karloff's defeat in Vancouver paved the way for the first series of Jaegers, Mark-1, produced at the PPDC Proving Grounds on Kodiak Island. The Mark-1s were produced in a short period of several months to effectively counter the Kaiju.

As a result, a design flaw in the Mark-1 Jaegers—the lack of radiation shielding—left pilots exposed to radiation poisoning and at risk of developing cancer-related illnesses. Four of the five Jaegers produced after Brawler Yukon were deployed to Russia, China, and Japan, where they would serve as the first line of defense against any Kaiju invasions that might emerge in those regions.

The Mark-2 and 3 presumably addressed the issue of protecting pilots from radiation. Later, the analog technology of older models was replaced by digital technology in the Mark-4, such as the Crimson Typhoon, and in the Mark-5, the Striker Eureka.

Both types pose a lower risk to pilots outside of combat against Kaiju. However, the changing size and strength of the Kaiju hampered the United Nations' financial capacity to fund the Defense Corps and continue financing the construction of Jaegers.

BASE OF OPERATIONS:

The defense corps established its first Shatterdome in Hong Kong, China in 2015; followed by seven others.

Built between 2016 and 2019 in Lima, Sydney, Tokyo, Vladivostok, Russia; Los Angeles, Panama City, and Anchorage. The decline of the Jaeger Program within five years led to the closure of the seven Shatterdomes built after Hong Kong.

Education:

A Jaeger Academy was established to train personnel who volunteered or enlisted in the program for various positions, including becoming Jaeger pilots. The academy was closed along with the end of the Jaeger Program.

Starting point
On September 15, 2014, Dr. Jasper Schoenfeld attended a global conference in Seoul, South Korea, convened to discuss how to address the growing threat of creatures known as "Kaiju." When the question of what to do was raised by liaison Stacker Pentecost, Schoenfeld seized the opportunity to present his idea for Jaegers at the conference.

Conception
With financial approval from the United Nations, the Jaeger Program and the formation of the Pan Pacific Defense Corps were underway. Although the cost initially made the PPDC hesitant to continue funding it, Stacker Pentecost's assistance proved helpful in convincing PPDC superiors to continue supporting the program despite its costs, even though it risked testing the effectiveness of the Pons System without full assurance of its safety.

Brawler Yukon, the first Jaeger Mark 1 prototype, was first tested on January 30, 2015, by U.S. Air Force Captain Adam Casey. While the concept was sound, the idea of ​​a single human piloting a Jaeger proved unfeasible when the neural payload sent from the Pons triggered a seizure that killed the USAF Captain.

The following month, when the second test seemed nearing imminent failure, Dr. Caitlin Lightcap, the creator of the Pons System, used the Pons from the observatory tower overlooking Lieutenant Sergio D'Onofrio's test and connected with his mind through The Drift. The immediate connection created a viable means by which the human mind could carry the burden of the neural load with the assistance of another.
