Warnings: Nihilism, Cambodian Genocide, The Killing Fields, organized crime, drugs, human tracking, post-humanism

Notes: Due to his pale complexion and hair, it's safe to assume Monsoon is an albino. That means he suffers from photo sensitivity as a human. His skin burns easily and bright lights hurt his eyes. He will rarely be seen without a pair of sunglasses on as well as keeping most of his body covered.

Full details on his past are unknown, although he claimed that he inherited his stance on killing people or ending up killed and his nihilistic views from the Cambodian capital city of Phnom Penh and the reign of terror from the Khmer Rouge regime and the Killing Fields between 1975-1979. At some point later, he joined a Cambodian organized crime syndicate, and was rumored to have had involvement in the drug trade and human trafficking. He also mastered the use of sai weapons, and his crime record was extensive enough to far outrank any ordinary gang member. He eventually got cyberneticized with a magnetics-based body after being caught in a gang shootout and mortally wounded. It was at this point that he decided to work with the Delaware-based PMC Desperado, apparently feeling it was much safer to work at a PMC instead of in a crime syndicate.

In 2016, he and Steven Armstrong took interest in a Brazilian swordsman named Samuel Rodrigues, who had killed several drug cartel members, and likewise arranged for his arrival in Denver, Colorado. While waiting for Sam's arrival, he and Armstrong had a small chat regarding the newly renovated reception area, with Armstrong expressing disgust at the cherry blossoms, and Monsoon viewing them as simply existing, neither beautiful nor ugly. He later encountered Sam face-to-face within a hangar area of the HQ, where he questioned Sam's motives for attacking drug cartels and leaving Brazil. He then proceeded to leave, although not before dropping a RP grenade on Sam and summoning a Metal Gear RAY UG for him to fight. He later contacted Sam, informing him when Sam insinuated that he'd tear the group apart that even if he did tear the limbs off, he still couldn't kill their organization.

Two years later, Monsoon intercepted and confronted Raiden before World Marshal HQ, and with Sam bearing witness, fought Raiden. Having been informed by Sam about Raiden's stance regarding his sword as a tool of justice, he then told Raiden that he considered the "pretty meme" to be "exquisite," and also revealed their similar pasts of "growing up on the killing fields." Raiden, already emotionally unstable from Sam’s earlier speech regarding the same subject, succumbed to his "Jack the Ripper" persona and admitted that he hid behind this excuse to conceal his true nature. Sam eagerly accepted Raiden’s sudden aggression, but Monsoon dismissed Sam, wanting the battle for himself. Monsoon noted that he misjudged Raiden and that Raiden really was like his group after all. Jack the Ripper offered to "demonstrate" to Monsoon where his childhood nickname of "Jack the Ripper" came from.

Monsoon dueled with Jack the Ripper, while mocking the Ripper's potential. Monsoon also hurled various military vehicles at Jack, split himself apart to avoid blows, summoned large heaps of vehicles to run Jack over, and eventually hurled an obelisk at Jack as if it were a missile. Jack evaded the last attack and rammed him into the side of World Marshall HQ before stamping on his chest repeatedly. Afterwards, Jack decapitated Monsoon after slicing his body to shreds, which promptly exploded after Monsoon's head fell to the ground.

Afterwards, his disembodied head mentioned that he'd "return to the earth" and that he succeeded in imparting a meme onto Jack. After Monsoon died, his tactical sais, named Dystopia, were later copied after careful analysis of his battle data. Raiden and Kevin Washington later deduced from Monsoon's comments to the former that Monsoon's train of thought was likely formed due to his early life under the brutal rule of the Khmer Rouge, but nonetheless agreed that it was still no excuse for Monsoon's crimes.

Monsoon is a true product of his upbringing. Having grown up under the Khmer Rouge he spent his childhood immersed in a hellscape of humanity's worst aspects, and was irreparably formed by the things he had to do in order to survive. Being made to work as an executioner in what came to be known as "The Killing Fields" Monsoon had been forced to take human life on dozens if not hundreds of occasions by the time he'd grown into a man. Dealing with such a horrific process for years on end resulted in him developing a very grim view on the world in general, adopting a hardcore nihilistic outlook that the one rule that existed in the world was to "kill or be killed." Even after being liberated from the persecution of Pol Pot's regime he would continue to hold this view, becoming further galvanized by discovering Richard Dawkins' book "The Selfish Gene."

Learning about Meme Theory introduced Monsoon to the notion that people are merely the byproduct of the memes that are passed-on to them, and this would only contribute towards his nihilistic outlook. The subsequent treatment he received after the fall of the Khmer Rouge further reinforced this idea and firmly established the that free will was well and truly a myth. Viewing himself as nothing more than the result of the memes passed on to him by others he moved through jobs that suited the skills he'd picked up in his role as executioner, blowing from criminal outfit to criminal outfit. As the years passed he would become more and more fixed in his views that existence is meaningless, growing versed enough in his this that he could even debate and poke holes in the fallacies of other's viewpoints. Despite how committed he'd become to this well-weathered exterior of uncaring callousness, beneath all the nihilism lay a sliver of the young man that could have been.

Outwardly espousing that nothing in life mattered Monsoon secretly maintained a part of himself that yearned for something to matter despite it all. He invested himself heavily into the arts of Ninjitsu and Okinawan Kobudō and seemed to take genuine joy in the skill with which he wielded them, however much this conflicted with his own ethics. The most telling example that a piece of himself that valued his own life still remained (or that he still possessed instincts of self-preservation at least) would be seen after he received mortal injuries in a shootout. Rather than just "returning to the Earth" as he so often claimed is the fate of all living things he would instead undertake a costly cybernetic augmentation process, saving himself from his extensive injuries and being reborn as exactly the sort of super-powered Ninja kids idolize. This sliver of hope would be further pulled-upon when he met with Steven Armstrong, who's ironclad beliefs and wish to tear down the post-Patriots corruption that gripped the world resounded with Monsoon on a deep level. Despite his best efforts to remain jaded these ideals perfectly touched on those aspects of Nihilism that he truly believed-in while also showing a way towards a future that he could genuinely prescribe to.

Further adding to the enigma that Monsoon had become was the fact that he was quite well-spoken, and seemingly quite well-educated and well-read. While many of his compatriots within Desperado expressed themselves through frequent vulgarity and no small amount of swearing Monsoon kept an almost squeaky-clean vocabulary. Preferring to debate his opponents rather than simply insult them he took an obvious joy in picking people apart, but in a way that suggested an enjoyment of the back-and-forth rather than simple bullying. Likely due to his time learning martial arts Monsoon modeled his cyborg after traditional Ninja clothing and equipment, suggesting he held an appreciation for both Japanese culture and architecture (further supported by him seemingly feeling defensive when someone expressed negative views towards either.) Whether through his own education or through his experiences after becoming a cyborg, Monsoon also seems to possess a significant understanding of magnetism. His wargear is masterfully crafted to both implement cutting-edge electromagnetic technology as well as to be molded after the arts he himself wielded, and all of it had the definite feeling of having been tailored to his exact tastes.

Monsoon is, by everything that we can see, a man eternally torn in two directions. On the one hand is the side of him that has come to exist through decades of blood, death, and trauma: A deeply callous and hardened man, espousing and feeling that nothing matters, who seems to yearn for the eventual death that will come to him but lacks the nerve to end his existence through his own means. On the flip side of that is the man he could and would have been had it not been for the Khmer Rouge: A sharp and capable man with a deep appreciation for both science and tradition and a hope to see the world bettered. Both these exist at all times within Monsoon, but the memes that have been so cruelly passed to him prevent him from ever being able to be able to rectify one with the other.

Monsoon's body was a unique cyborg chassis consisting of a series of segments held together by powerful electromagnetic forces which could separate considerable distances while still remaining part of the whole. This ultimately allowed Monsoon to perform incredible feats that other cyborgs couldn't such as dodging sword slashes and separate his body to increase his reach or attack from multiple angles at once.

In addition, the generator was powerful enough to even allow Monsoon to lift even huge objects like Stryker APCs and Hammerhead gunships in the air to hurl at Raiden. The generator was also refined enough to also lift up objects that at least possessed trace amounts of metal, as evidenced by Monsoon's lifting of a reinforced concrete obelisk. This also granted him the ability to stick on metal structures, as his magnetic abilities allowed him to walk upside down such as when he first introduced himself to Samuel Rodrigues.

The cyborg body itself was highly maneuverable with incredible jumping abilities, being on par of other powerful Cyborgs like Raiden. His eyes were hooked up to cables that attached to a bump in his helmet. Similar to Raiden, Monsoon's cybernetic feet also had extensions at his heels. The electromagnetic generator was activated by part of his visor extending outwards.

However, even with all of his unique traits, Monsoon's electromagnetic abilities had their weaknesses. His body was not unique from other cyborg bodies as his was still susceptible to EMP grenades, and a direct strike at the extended generator would instantly cut him off from his electromagnetic abilites, also stunning him briefly (though he can reactivate his electromagnetic abilities again once he had recovered from the initial blast at any given time).

In addition to his magnetic abilities, Monsoon also carried a pair of sais called "Dystopia," which he was extremely skilled with, and a belt with pouches containing red phosphorous grenades. He used the latter to disorient foes, attacking from multiple directions.
