Raiden

"I am Lightning. The rain transformed."

- Raiden

Raiden (雷電), real name Jack, was a Liberian-American special forces soldier responsible for resolving the 2009 Big Shell Incident as a new recruit to the reformed FOXHOUND unit. A former child soldier under Solidus Snake, Raiden had been selected by the Patriots to test the S3 Plan at the Big Shell. He later worked alongside the Paradise Lost Army in their anti-Patriot activities, but was captured and forced to undergo heavy cybernetic experimentation. After successfully escaping, Raiden went on to assist Solid Snake during Liquid Ocelot's Insurrection. He later joined the PMSC Maverick as a means to support his family, but re-entered the battlefield once more after Desperado ruined one of their missions, leaving him injured.

Early life and career
Jack was born on a rainy day in Liberia. During his youth, in the turbulent period that was the Liberian Civil War, Jack was adopted by Solidus Snake, who became his godfather after he killed his parents. Jack was subsequently raised as a child soldier and later fought in the Civil War in 1989. He and other children were shown Hollywood action films daily for "image training," and were given food mixed with gunpowder containing toluene to make them more controllable. On one occasion, Jack was injected with an unknown substance during a physician's experiment. On another, Jack witnessed Solidus demonstrate to him that blades were a "noble weapon" compared to guns, by slitting another soldier's throat in front of him. Under Solidus Snake, Jack became a killing machine, known alternately as the "White Devil" and "Jack the Ripper" due to his incredibly high kill rate compared to other boys his age, as well as a reference to his being one of the few Caucasians born in Liberia. Armed with a gun at the age of six (he would later remember it as an AK rifle), as well as a knife, he proved to be a superior soldier, rising to become captain of the Small Boy Unit at ten. His skills with a bladed weapon, as well as his cruelty in dispatching enemies with them, was another reason for his "Ripper" nickname.

After the war ended, Solidus had him placed in a relief center, but he was later removed by a non-governmental organization and taken to the United States. There, Jack came into the hands of the Patriots, who implanted his cerebral cortex with a high concentration of nanomachines, in order to have him function as a back-up system for an optic-neuro AI. The Patriots chose him out of the other child soldiers in his unit because unlike the others, who would live up to their pasts and pay dearly for it, Jack did not accept his past and hated it. The same nanomachines were also capable of memory manipulation by connecting or stimulating synapses, primarily nerve sections in the dormant part of the brain. In addition, Raiden was not listed under any of the United States databases (e.g. the FBI, NSA, CIA, etc.)

Jack would grow up to suppress the memories about his terrible childhood, burying the memories of his bloody past, though he still suffered from nightmares of his past nearly every night. Now living a life in the United States, Jack joined the military where his admirable skills were at first recognized by the U.S. Army's Task Force XXI, although unlike other members of Force XXI, he was not involved in the Genome trials. From there he participated in three hundred VR simulations, including a re-creation of the Shadow Moses Incident that took place a few years earlier. He had eventually left the Force XXI group by January 20, 2007.

On April 30, 2007, Jack met Rosemary after transferring to Fort Hamilton at New York City, and had an argument about King Kong. After they parted ways, they met again afterwards, shocked that they worked in the same place. Eventually, Jack grew to love Rose deeply, but his harsh experiences had left him melancholic and emotionally distant, and he constantly shut her out of his problems. In large part because of his PTSD-induced nightmares, he also refused to sleep next to Rose out of fear of hurting her. Most times when they did get together, he either stayed awake all night or otherwise left Rose's place, and he wouldn't let her in his bedroom. This eventually cumulated in Rose entering his room without his permission, which was devoid of any personal objects save for a bed and a desk. However, all of this drama was a ruse by the Patriots to gain more control over Jack's life, with Rosemary acting as a spy.

Sometime prior to the Big Shell Incident, Jack was recruited into the supposedly reformed FOXHOUND, a special forces unit that no longer officially existed. One of his "training sessions" at "FOXHOUND" was at Fort Polk, within a mock Afghan village.

At the beginning of the Big Shell mission, Jack was briefly referred to as "Snake" before his codename was changed to "Raiden" by the Colonel, as the leader of the terrorists was also referring to himself as Solid Snake. Prior to being dispatched, Raiden's superiors also removed his natural blood, placed it in cold storage, and replaced it with a nanite filled blood substitute instead. On his way to the Big Shell, he also found that the oil fence had a recently-cut hole, implying that someone other than him had managed to sneak in. He later revealed this to the Colonel, who was surprised, since there wasn't supposed to be anyone other than Raiden who should have infiltrated the base. His suspicions that there was another intruder were quickly confirmed, as he entered a room full of knocked out guards and caught a glimpse of the man as he ascended in an elevator. Raiden took to the mission with some hesitation, claiming to have only been trained in VR missions (some of which didn't cover vital materials such as disposing of C4).

Raiden later met up with Iroquois Pliskin, a Lieutenant Junior Grade with the U.S. Navy SEALs, but he was revealed to be the real Solid Snake, who had faked his death two years prior during the Tanker Incident. Raiden eventually learned of the Patriots' existence, as well as the development of Arsenal Gear, an enormous warship for which the Big Shell acted as a disguise. He also rescued Arsenal's AI engineer Emma Emmerich and attempted to escort her to safety, although she was later killed by Vamp despite his best efforts. Throughout the mission, Raiden also harbored some suspicions that he may enjoy killing people, although he did not know why. Raiden and Snake were able to join forces to take down Dead Cell and upload a virus into GW, Arsenal's AI. He was then seemingly betrayed by Snake and was subsequently captured by Olga Gurlukovich. Taken aboard Arsenal, Raiden was later freed by Olga, telling him that they had needed to use him so that Snake could sneak on board.

As Raiden snuck through Arsenal Gear's interior, the Colonel began to act strangely during Codec transmissions. Pressing on, Raiden made his way to rendezvous with Snake, and was eventually contacted by Rose. She admitted to him that she was actually a Patriot spy sent to keep tabs on him, though she insisted that she had genuinely fallen in love with him. This greatly angered Raiden, but her transmission was cut off, just as she revealed that she was pregnant with his child. Raiden then met with Snake, who gave him most of his equipment back, along with Olga's high-frequency blade. Suspicious about his C.O.'s odd behavior, Raiden had Snake's partner Otacon investigate, who eventually learned that the Colonel was actually an AI construct of GW, partially based on the manipulation of Raiden's memories. After the Colonel claimed that Rose was being held hostage, Raiden began to fear that Rose didn't exist either, and that all his memories of her might have been falsified. After some reassurance from Snake, the pair battled through the Arsenal Tengu commandos before encountering Dead Cell's leader Fortune. Snake told Raiden to go on ahead, with Fortune claiming that Snake was the root of all her misery. Raiden, hesitant at first, left Snake to face her alone.

Raiden went on to battle against a 3 to 25 mass-produced Metal Gear RAY units, managing to defeat several of them before collapsing from exhaustion. Just as Raiden was about to be killed, Olga came to his aid. By doing this, she revealed herself as an enemy of Solidus Snake, who angrily killed Olga. Olga's final words were for Raiden to live. As Solidus ordered the remaining RAYs to kill Raiden, the virus uploaded into GW went into effect, disabling the RAYs. Solidus then destroyed them out of frustration.

After Arsenal crashed into Manhattan, it was revealed that Raiden was merely a puppet of the Patriots, and that his entire mission on the Big Shell had been carefully scripted. AI representations of the Colonel and Rose told Raiden that he was just a weapon, a creation of the Patriots with no purpose but for what they made him. The AI instructed Raiden to kill Solidus, which he had no choice but to do so, for his own sake and for the sake of Olga's daughter and Rose/their unborn child. Raiden, however, also expressed disgust towards the Patriots' actions, and made it clear beforehand that he will not follow their commands anymore. Solidus also desired to kill him so he could access the backup data of the Patriots that was stored in his cerebral cortex in order to track them down, to compensate for the apparent destruction of GW. A fierce battle on top of Federal Hall ensued, and ended with Raiden emerging victorious over Solidus. He was reunited with Snake, who assured him that he was not the puppet of anyone, and that he could shape his own destiny. Raiden offered his services to Philanthropy, but Snake told him to take care of his personal affairs first. Raiden then met with Rose, and he solemnly forgave her, with the two ultimately deciding to continue their lives together.

Post-Big Shell
Raiden and Rose began living together. At some point, Raiden, in large part because of his having to utilize a HF blade weapon late in the Big Shell Incident, became fascinated with the art of Japanese swordskills, training himself with the HF Blade and studying in various Japanese swordsmanship and the samurai code, and even going as far as to watch samurai movies. Despite the loving relationship between him and Rose, the tragic memories of his days as a child soldier started to resurface, causing tension in their relationship. He began drinking heavily, getting into fights and eventually decided to leave her. In addition, he was also led to believe that his child had died from a miscarriage.

Raiden learned from Big Mama, in exchange for the location of Big Boss that he obtained from GW, that Olga's daughter, Sunny, was being held in Area 51, and successfully rescued her with the help of Big Mama and the Paradise Lost Army. It was during his rescue of Sunny that he met the former Soviet soldier Boris Vyacheslavovich Popov, who was the war buddy of Sunny's grandfather, Sergei Gurlukovich, who aided him out of the realization that the Patriots were a threat to the world, not just America. After hearing of Rose's miscarriage and subsequent marriage to Roy Campbell, Raiden became despondent. He left Sunny in the care of Otacon and Snake anonymously. Afterwards, he left to wander the Earth. Raiden studied scouting techniques under a Native American shaman living in Alaska, and learned to hunt. He then began work on retrieving Big Boss's remains from the Patriots for the Paradise Lost Army, leading to his capture. As a prisoner, the Patriots used Raiden as a test subject for experiments in exoskeletal enhancement surgery, during which he had his head and spine excised from his body from his lower jaw down and subsequently grafted into an enhanced synthetic body.

With the help of the Paradise Lost Army, Raiden managed to escape his captivity. After undergoing surgery to clear his body of nanomachines and being saved by Dr. Drago Pettrovich Madnar, he was successful in reclaiming Big Boss's remains from the Patriots. The enhancements implanted throughout Raiden's body, however, were too severe to allow him to live a normal life again. He elected to disappear from the life of his fiancée, Rose.

Raiden returned in 2014, and while Solid Snake was in South America, he contacted him through Codec, commenting that he had been helping Big Mama find the corpse of Big Boss. He also now felt as if Raiden was his only name, disavowing his identity of Jack when he first contacted Snake. Their first call ended abruptly due to a firefight, though. Shortly after Laughing Octopus was defeated, Raiden contacted Snake again, helping him track Naomi by teaching him how to scout. Raiden appeared in person in a South American marketplace, where he helped Snake and Otacon escape by fighting off the Gekko. In order to disguise his current appearance, he frequently took to wearing a black duster, although he discarded it when fighting the Gekko.

Eventually, the Gekko held him captive on behalf of Vamp, who stabbed him twice with his knife and tasted his artificial blood. While believed by his opponent to be "immortal," Raiden replied that he simply didn't fear death. Snake then shot the tethers, freeing him from the Gekko, which he subsequently destroyed. Raiden and Vamp engaged in a fearless battle with their two swords and array of knives, respectively (at one point the contact between their weapons was so fierce, Raiden's sword began to glow red hot). Their battle resulted in Vamp standing to Raiden's back. Raiden's decisive attack would prove his earlier statement that he did not fear death: he ran his sword through his own abdomen, but impaled Vamp as well. The battle ended, both of them having inflicted serious wounds on the other. When Snake and Otacon's helicopter hovered above him, he jumped aboard and escaped along with Naomi Hunter, but not without collapsing from the grave injuries he sustained from the previous fights. Aboard the Nomad, he continued to suffer even more due to his injuries, causing his chances of survival to become very bleak. Naomi had sympathy for him, as her adoptive brother and Raiden had both endured a great deal of suffering as a result of each becoming a Cyborg Ninja, and was extremely bitter that such experiments were still continuing.

After the beginning of a "white blood" transfusion and dialysis with the help of Dr. Madnar, Raiden attempted to join Snake on his mission to Shadow Moses, motivated largely by his belief that only by helping Snake defeat Liquid can he truly break free of being a pawn by the Patriots' proxies, as well as feeling that he's alone otherwise thanks to the miscarriage and his separation from Rose, plus the loss of both his birthparents and his innocence due to his becoming a child soldier by Solidus Snake. However, Snake refused to let him come along, both due to his dialysis not being complete yet, and his belief that Raiden following him will result in him "not seeing the day" due to Snake being "a beast" and "a shadow which no light can touch." Eventually, with his dialysis being completed, Raiden returned again and saved Snake's life at Shadow Moses Island after disabling the Suicide Gekko that were attacking. He then had a final face off with Vamp atop Metal Gear REX, after Snake had returned the latter to a mortal state via nanomachine suppressors, with Raiden emerging the victor, finally killing Vamp once and for all. He also relayed a coded message from Sunny to Naomi, regarding the completion of the FOXALIVE computer virus, shortly before Naomi used nanomachine suppressors to both euthanize Vamp and commit suicide, much to the group's shock. Proceeding to make their escape, with Snake controlling REX, Raiden assisted by warding off the Gekko chasing them, eventually being caught under debris caused by the Suicide Gekko's detonation. He set himself free from under the debris by cutting off his right arm. After doing so, he put himself in the way of Outer Haven, stopping it in its path and holding it back from crushing Snake, allowing him to get out of the way. Raiden was eventually crushed beneath the vessel, screaming Rose's name and recalling both their first meeting and reunion after the Big Shell Incident, before losing consciousness. He was later confirmed to have survived by Otacon but was in no condition to help Snake in his final mission aboard Outer Haven.

However, as Snake made his way deeper into Haven, he was saved once again by Raiden, missing both arms and wielding his sword between his teeth, from a group of Haven Trooper. He also demonstrated lightning-like powers. Raiden originally intended to upload the FOXALIVE virus into GW in Snake's place, stating that his current state made himself immune to the microwave corridor, but Snake convinced him to not do it as he "still has his youth." Instead, he decided to hold the FROGS off and buy Snake enough time to upload FOXALIVE. He was able to kill several of them but was eventually overwhelmed and taken down. Once Snake and Otacon destroyed GW along with the other four AIs, the FROGS were incapacitated and unable to kill him.

Afterwards, Raiden was sent to a hospital where he was fitted with a new cybernetic body that featured artificial skin, giving him a somewhat more human appearance. Following Raiden's surgery, Rose and her son John paid him a visit, though Raiden ignored them both, believing that the child was Campbell's, who Rose had married during Raiden's estrangement from her. Rose told Raiden that the child was in fact his, and her miscarriage had been a lie. Her marriage to Campbell had actually been a ploy to protect herself and their son from the Patriots, so that he could not be used as leverage against Raiden. In other words, Raiden's lack of awareness of his son and his disdain for Rose meant that both would serve no purpose to the Patriots, as their suffering would not move him in any way. Stunned, Raiden forgave Rose once again, as she felt desperately guilty from being unable to tell him from the danger it presented. She proceeded to introduce their son as and the three huddled together in reunion. To him, at that moment, it felt like a scene from Beauty and the Beast. But Rose reassured him that he was no beast, but her husband. Raiden then vowed that he was done running, while Rose vowed that she was no longer afraid.



Civilian Life
Following the end of the war economy, Raiden attempted to return to a normal, civilian life with his wife and son. During this time he attempted to look as normal as possible, but the technology behind his artificial skin was imperfect and still looked unnatural. He also continued to suffer from paranoia, stemming from being manipulated by the Patriots in 2009. His inhuman appearance caused him to be ostracized from society and made securing employment even more difficult during the post-SOP economic recession, when even non-cyborgs had difficulty finding work.

Joining Maverick


In time, Raiden decided to return to the military sector, seeking a non-combat position so that he could provide for his family. Raiden encountered Boris again and, after discussing Maverick Security Consulting, Inc., accepted Boris' request to join the PMC as a full-time employee, forgoing the typical contraction method. At this time, Raiden had his original cyborg body upgraded, outfitting it with a more natural jaw using artificial skin, substituting the dual Solid Eye system with a single artifical compound eye unit, and replacing its outdated organic polymer muscle fiber with modern carbon nanotube muscle fiber. This allowed him to pass for a normal human, at least while clothed, and gave him the capacity to carry out bodyguard work and other missions that didn't require serious combat.

His first missions for Maverick had him working with Kevin Washington, where they were hired by the Carabinieri to track down three Albanian mafiosos that fled Italy for Montenegro, with orders to retrieve them. The mission grew complicated in spite of his claims of having reviewed the mission details, due to the three mafiosos having undergone cybernetic upgrades, with Kevin being the main reason he got through the mission. Kevin will later reference this mission when Raiden ended up going to Abkhazia nearly three to four years later, when Raiden mentioned going through the materials. He rarely got to see his family because of his line of work, but the few times he did see his family always put a smile on his son.

For three years starting 2015, Raiden was part of Maverick's recovery efforts to help rebuild an African country that had undergone a bloody civil war. Raiden himself did VIP protection, military training, and other related jobs. He eventually met up with the African country's prime minister N'mani, where the latter congratulated him on Maverick's contribution in the rebuilding of the country. Because his real name still painfully reminded him of his past, he still went exclusively by the name of Raiden. However, N'Mani had a good sense of humor to jokingly call him "Mr. Lightning Bolt" when he learnt what Raiden's name translated to.

Desperado Incursions
"I told myself this was about justice, about protecting the weak. But I was wrong."

- Raiden in 2018

Cyborg attack
However, plans abruptly changed in 2018 when cyborg soldiers belonging to the Desperado Enforcement LLC. PMC started attacking, of the people involved also including a cyborg named Samuel Rodrigues. With Maverick unable to identify their affiliations, Boris ordered Raiden to take out the cyborgs. Although the prime minister was to be protected, the Desperado leader Sundowner had managed to abduct him after several cyborg soldiers ambushed his limo near the port along with a modified Metal Gear RAY unit. Raiden and Sundowner then encountered each other, with the latter also referring to him as "Jack." Raiden then learned that Desperado wanted N'mani dead because Africa's been getting "too peaceful" under his reign, as Sundowner wanted to restart the war economy due to feeling that it was his livelihood. Raiden was forced to confront the PMC's modified Metal Gear RAY while Sundowner made his escape, which he fought three times due to its persistence and eventually cumulated to Raiden running his HF Blade down its spine. After tracking the Desperado leader, Sundowner, the Prime Minister, as well as Sam down to a train, Raiden was forced to watch Sundowner kill N'mani. Raiden then attempted to follow through with N'mani's last words to stop Sundowner, but Sam prevented him from getting to Sundowner. Raiden then did battle against Sam within the train tunnel. However, he was unable to keep up with Sam's cyborg enhancements which were superior to Raiden's cyborg outfit. The result was Raiden would end up having his left arm amputated and having his left eye irrepairably damaged, the former of which he lamented having lost one again. Nonetheless, he managed to buy enough time for the train to pass through the tunnel before Sam could kill him. He managed to crawl back up onto the train, and passed out while witnessing Sam escape. Ultimately, he was unable to stop Sundowner from killing N'mani.

Custom cyborg body
His arm was later retrieved from the battle site and analyzed by Maverick, as well as having to undergo a weekly retrieval of files stored on the arm, due to the files being corrupted. During the procedure, they also had to replace memory units in his nervous system, and he was also losing a lot of blood due to his earlier wounds, forcing the doctors to put a clamp on him, which also resulted in Raiden flashing back to his time as a child soldier in Liberia, where he was injected with something. The doctor then managed to resuscitate Raiden and ordered the beginning of the optical implant, with Raiden wondering what happened to him. Afterward, they had to remove his left eye, as his optical nerve was completely destroyed, resulting in him flashing back to his watching war footage as a child soldier. The memory bank procedure is then interrupted when a mysterious figure arrives in the OR with the doctors denying him entry before Raiden demands who it is and for the person to come closer. Upon the realization of who he is, he angrily demands to know where "he" is to the figure.

At some point, both as a direct result of the attack and Raiden's injuries, and under his personal request, Raiden underwent a full-body cybernetic conversion, as he felt the Patriots "didn't leave him much of a body to begin with." This, alongside Maverick's previous cybernetic maintenance person going into hiding resulted in him being performed on by a German cyberneticist nicknamed "Doktor" (which was also the latter's first time doing full-body conversions). After his surgeries were finished, the mysterious figure then presented Raiden with his new sword, to which Raiden later flashed back to witnessing Solidus slitting a soldier's throat. Raiden was originally supposed to get a completely cybernetic eye to replace the one he lost, but Doktor was unable to create it before the surgery, so he had to wear a makeshift eyepatch for a while.

Foiling the coup d'etat in Abkhazia
Upon acquiring his new Cyborg Ninja body, Raiden was instructed to undergo a VR Training simulation that Doktor created so he could get used to his new body before redeployment. Under the guidance of Boris, Raiden honed his new body's blade, developed various attacks against cyborgs, became affluent in tracking as well as acquiring an enhanced running capability. Raiden, upon returning to active combat, aggressively chose Maverick missions that directly related to Desperado's activities. Afterwards, he was deployed to Sukhumi, the capital of Abkhazia, on a flying wing, where he was then launched when nearing insertion by a rocket platform, in order to quell a military coup that resulted in the Abkhazian president and most of his cabinet being killed. He also was requested by Doktor to retrieve the left hands of any cyborgs that he defeated, largely due to the valuable data stored on their arms, in exchange for both the surgery and any future upgrades. Raiden's new body was powered by a Molten Carbonate Fuel Cell which needed frequent recharging via Electrolytes extracted from enemy cyborgs during battle. Upon arrival, Raiden was ambushed by several Desperado soldiers via stealth camouflage, although his upgrades effectively made their efforts to kill him fruitless.

Making his way through the old city crawling with cyborg patrols and Gekkos, he also encountered the IF Prototype LQ-84i unmanned weapon that was deployed to assassinate Raiden. However, he managed to subdue it and have it delivered to Maverick in order to have the "Doktor" repair the weapon as well as make some adjustments to the K-9000, known as the Bladewolf, which included the disabling of its remote piloting program and its AI wiping program. Raiden eventually managed to reach Desperado's main base in Abkhazia, a production plant near the coast. He then fought with the leader of the forces stationed at Abkhazia, Mistral. After a grueling fight that descended to the bottom level of the plant, he eventually disarmed her of her weapon, which eventually cumulated in him finishing her off after she was doused in liquid nitrogen while she backed away. Afterwards, when Andrey Dolzaev called Mistral upon her death, Raiden picked up the radio and told him to surrender. However, when Dolzaev refused, Raiden deduced from his reply that he was actually intending to blow himself up near a power pylon as his final act, but was unable to stop him in time. Informing Boris of this development, he was then instructed to find an landing zone, as they were sending a chopper to extract him from the area. Raiden later received a copy of the Etranger from Maverick and Doktor, having developed it from careful analysis of Mistral's combat data.

Infiltrating the Mexican research facility
Eventually, as a way to "throw him a bone," he allowed the Bladewolf to accompany him in his missions as a scout. At some point later, he and Bladewolf were dispatched to Guadalajara, the capital of Jalisco, one of 32 states within Mexico, to infiltrate a research facility. After crossing south to the border, Raiden stopped by a souvenir shop and purchased a Mariachi uniform (traditional garb for Mexican folk musicians) in a misguided attempt to blend in with the locals. He then drove a black convertible until he spotted a sewer grate, to which he then entered the grate, although he was briefly spotted by two bewildered pedestrians.

Afterwards, he, under the cautions of the Bladewolf, carefully navigated the cyborg-infested sewers before being ambushed by a Mastiff cyborg. Although willing to go through the sewers if it meant finding a Desperado lab, Raiden nonetheless felt uncomfortable doing so, especially after his briefing referenced the gas explosions in the Guadalajara sewers back in 1992. After eliminating it, he then used the catwalks to evade being spotted by the Mastiffs. He later rescued a Guyanese boy named George who had escaped from the facility. Learning that the facility removed brains from human children, and also the exact method of escape the boy went so he could narrow down the location, he placed him in a safe place while also issuing Maverick agents to retrieve George.

Upon finding the facility's entrance, Raiden, taking Doktor's advice of using a DOOMP to access the facility's video records regarding their development, decided to hijack a Dwarf Gekko. While attempting to locate a Dwarf Gekko, he stumbled upon a room containing cyborg brain casings, and after defeating several enemies, he reported his findings, causing them to deduce that the brain surgeries on the trafficked children related to cyborg development somehow. After finding a Dwarf Gekko and having it locate a mainframe system to access, he had the files forwarded to Doktor. He then learned that most of the kids have likely had the brains removed and sent to a facility in America, and also noticed that Sundowner and another VIP, whom Kevin recognized, inspecting the facility in the video files. He later learned from Courtney that the agents couldn't find George. As he made sure the calculations based on the GPS data were correct, he deduced that Desperado had beaten him to it. He then encountered a Grad that was blocking his way and defeated it.

Afterwards, Raiden learned from Kevin the identity of the VIP: Colorado Senator Steven Armstrong, and also deduced that World Marshal, the PMC he had previously been investigated by a Grand Jury over in 2016, was involved in Desperado's activities, and acted as their supplier of cyborg personnel. Raiden wanted to expose Armstrong and World Marshal for their actions, but Kevin suggested against it. He later stumbled upon a blood cryogenics chamber, and deduced with Doktor that this was what allowed them to preserve the brains for transport, and presumably the rest of the bodies that weren't needed. He later found the kids, but was then forced by the head researcher to not rescue the children (who were being exposed to chloroform) with George at gunpoint. Raiden then cut down the scientist after George temporarily overpowered the scientist. He then had George sent to Doktor to watch over him.

Corporate Raid at World Marshal HQ
"I think it's time for Jack, to LET 'ER RIP!"

-Raiden in 2018

Mile High City
Deducing that Maverick is not going to go after World Marshal for their actions due to the illegal nature of going after them, Raiden sent a resignation letter to Boris. He also decided to have Doktor arrive with a transport chopper when he's inside the building so they'd carry out all of the cyborg heads so he'd do surgeries on them that would ensure they at least had a relatively normal life outside of combat. He then made his way to downtown Denver to their headquarters building to rescue the brains, feeling that, even if he wasn't able to save them from becoming cyborgs, he can at least prevent them from experiencing the same childhood as he did during Liberia. He received a call from George, and he reminded him that he didn't want to kill, and that war isn't fun and games when explaining why he won't let George tag along.

Shortly after the call, he was ambushed by cybernetic Denver cops under World Marshal's payroll, as they effectively had control over the city. He then received a call from Boris, who angrily demanded an explanation for his resignation. Raiden explained his motives, before having to abruptly end the call due to squad cars blocking his path. Upon reaching a barricade vehicle, he decided to speed up enough to have the RPG blast flip the car over the barricade. The police then surrounded Raiden. Bladewolf scouted ahead, while he took on the police, wiping them out. He then made his way to the balcony to access the rooftops via an elevator, as the highways were coroned off by the police. He then explained to Boris regarding his actions that he doesn't want more "Jack the Rippers" throughout the world, hence why he has to do it. He also didn't have to worry about Rosemary and John being targeted by Desperado, as they were in New Zealand. As such, Maverick still supported him, albeit unofficially.

After traversing the rooftops, he then was instructed by Bladewolf to access an abandoned rail system dating back to the 19th Century. However, as it was abandoned, he also had to navigate the UG-infested area while in the dark. Afterwards, he then navigated his way through an abandoned district that was heavily armed with various cyborgs and UGs, including mass-produced versions of Bladewolf's LQ-84i form, the Fenrirs. He then arrived in the vicinity, where Sam utilized the banners to tell Raiden about how he has killed severals soldiers. He then reminded Raiden that the cyborgs, adults as they may be, had in fact felt forced to participate due to costs to gain cybernetics to even have a livelihood and not beg on the streets, even in America. With that knowledge, Raiden also heard the cyborgs' panicked inner thoughts, which gradually caused him to become emotionally unstable. Bladewolf then explained to Raiden that people are different. He then revealed that he knew Sam from three prior wars. He later made his way, with his emotional state being volatile, to the immediate premises of World Marshal HQ, but was beaten down just outside of the front door, with Sam and Monsoon greeting him and informing him about it being peoples' natures to kill and be violent. Raiden then released his Jack the Ripper persona, even going as far as to have his pain inhibitors deactivated to fully unleash it. He then killed Monsoon, although he vowed to Kevin after the battle that he won't utilize it for anyone else.

Hostile Takeover
Raiden entered the lobby and also heard Sundowner's announcement congratulating Raiden on killing Monsoon and telling him to "go wild." He then wiped out the soldiers guarding the area, after triggering alarms. The Elevators were deactivated because of Raiden's intrusion, although Doktor managed to hack into the elevator systems to ensure Raiden got in. Upon reaching the 20th floor of the lower half of the building (the regular workplace area), he then proceeded to destroy three power supply generators, including a backup supply, to deactivate a security gate for an elevator for the top half of the building where the research and development center was located. He also insisted that he keep his pain inhibitors off as he needed it. He then proceeded to rush through the enemy resistance, eventually jumping across several Sliders and run up a building to reach the top. After making his way through a Japanese Garden-styled room, he then proceeded to take a freight elevator to the top, although he had to fight several Desperado cyborgs and UGs before reaching the top.

Afterwards, he ended up reaching the floor containing the server room, although he had to fight body doubles of both Mistral and Monsoon before confronting Sundowner at the room. He then learned that they were subjecting the children to VR training because the real thing wasn't getting the results they needed, and also learned that there was an event that would happen that would render Raiden's efforts naught even if he saved all the children in three hours that Mach 2 would have him stop it in time, and would have reignited 9-11 style warfare. He then pursued Sundowner to the heliport, and fought against him. He then killed Sundowner after having a Slider crash into his Hammerhead late into the duel. Sundowner then informed him that the event was the beginning of Operation Tecumseh, but elaborated no further. Raiden and Maverick, when discussing it, then deduced that Operation Tecumseh involved ruining the peace talks at Pakistan to ensure another War on Terror. They then deduced from Courtney that they could stop the situation at Mach 23 speeds, which would take half an hour to get there, with Raiden requesting that they contact Solis.

Escape from Denver
Raiden then boarded the helicopter with Doktor as the pilot, having procured the brain canisters in the transport chopper. However, before they could get out of Denver airspace, they were ambushed by a pair of MQ-320s. The transport chopper had limited defenses, including an EMP generator that could deflect missiles, but not the drones themselves. Raiden then proceeded to jump out to hijack a drone so he could defend the chopper. After hijacking the drone by impaling his sword in its brain, he told Doktor to turn the chopper around (as it was being tailed by the other drone), which he then did, with Raiden then proceeding to cut down the other drone just as it was passing by him via his sword. However, the close proximity to the second drone also caused it to be damaged as well. Raiden then jumped to board the chopper, but the railing broke from the weight of his body. Raiden then fell into the cityscape. Doktor was forced to leave him due to cyborgs shooting anti-air rockets at the chopper, but he honored Raiden's sacrifice.

In actuality, Raiden survived the fall, although he had to fight through several cyborgs. Doktor, having learned of Raiden's survival, then contacted Raiden after Raiden took care of some cyborgs. Because the portion of Denver that World Marshal was at was evacuated, there were a lot of abandoned cars, so Raiden was going to borrow a vehicle. He also told Doktor to worry about delivering the brains, and also vowed that he'll keep his distance from what remained of World Marshal while heading to the Solis launch pad, which was fortunately also in Colorado. Bladewolf later stated that it will depart with Raiden for Pakistan after finding a way off the chopper. After Raiden cleared the final barricade, Raiden proceeded to take a motorcycle that caught his eye, although not before leaving a "note" etched into the ground stating that he needed to borrow the vehicle to its owner.

Duel at the Badlands
Making his way to Solis via motorcycle, he re-encountered Sam. Afterwards, Raiden and Sam decided to have a duel to the death, largely to see whose view will be remembered in history. After an intense duel, Raiden managed to kill Sam by impaling him through the chest. He also realized that Sam barely possessed cybernetics. He also supplied Bladewolf with Sam's sword, at the unmanned gear's request. Boris then reminded him that he had less than an hour to get to Solis. Raiden and Bladewolf then proceeded to leave for Solis.

Operation Tecumseh
Upon arrival at Solis, Raiden and Bladewolf met up with the check-in guard for their appointment with Sunny. However, Raiden, in the process of getting into Solis, accidentially broke the electronically locked gate, thinking it was open. After a brief exchange, Sunny then showed them the device she built. Raiden and Bladewolf boarded, thanking Sunny. Because of the limited time, they had to undergo ignition without a countdown. Less than half an hour later, Raiden arrived at close proximity to the Shabhazabad Air Base. After verifying with Kevin that it was the location of Operation Tecumseh, he proceeded to raid it. Sunny later informed Raiden about the gate, and informed him that she'll send an invoice requiring Raiden to pay for the repair and reinforcement costs, causing Raiden to lament that Rose will most likely "kill" him for the expenses.

After wiping out the security at the base, he and Courtney discovered that World Marshal's XIFF ID came up as "unaffiliated;" the same XIFF ID that Desperado had during the African ambush. Deducing that World Marshal intended to frame Desperado with the attack on the President, Raiden decided to destroy the control tower, hoping to cause enough damage to get the United States Military to realize something was wrong.

However, by the time he got to the control tower's vicinity, he discovered Bladewolf's prone body. Suspecting that an ambush awaited him, he carefully scanned for any potential enemies nearby, although the ground gave way underneath him. Jumping back to stable ground, he saw that the cause of the pit was a new Metal Gear called Excelsus. Senator Armstrong then stepped out of the cockpit and explained his motives regarding the fall of SOP and the ruin of the American economy. In addition, he also learned from both Boris and Armstrong himself that he currently didn't plan on assasssinating the President. Instead, Armstrong had framed the jihadi rebels for attacking the base itself via Desperado and had the President rerouted back to America. As Raiden was one of the few people who could expose the truth, Armstrong decided to kill Raiden with Excelsus. Raiden managed to defeat Excelsus by cutting off its front legs, throwing it onto stable ground, engaging it in battle with one of its blade arms, chopping up its head, and then impaling it with its own sword.

Afterwards, he had a fistfight with Armstrong, who had used Excelsus's wires to activate his nanomachines. Armstrong's nanomachines gave him the upper hand and he easily snapped Raiden's HF Sword in half with his bare hands. As Raiden was on the verge of defeat, Armstrong continued to elaborate on his full motives. Armstrong believed that America had rotted to the core, so he intended to remake America so the citizens will all fight, die, and kill for whatever they individualy believed in. He also expressed the sentiment that the weak needed purging. This prompted Raiden to stand back up and call Armstrong insane. Despite the best of his abilities, he was unable to defeat Armstrong, let alone do sufficient damage. However, Bladewolf had gotten back up, and after playing back a message Sam recorded before his death, supplied Raiden with Sam's sword. Raiden then reengaged Armstong, gradually overpowering him. Eventually Raiden plunged his arm into Armstrong and ripped out his nanite-altered heart, crushing it. Though he was considered by the public to be a person who hurt a lot of people, Sunny still viewed Raiden as a hero.

Afterwards, Raiden decided against rejoining Maverick, having resolved to fight his own war, albeit against more cyborg mercenaries contracted out to kill him. He also had his body restored to a more human looking body, complete with a new cybernetic eye to replace his left eye.

Names
The word "Raiden" (雷電) literally means "thunder and lightning" or "thunder god" in Japanese. He shares this codename with the Mitsubishi J2M Raiden, an Imperial Japanese WWII fighter aircraft, which the Allied forces codenamed "Jack." The Patriots, had named him after the plane and later informed Raiden that, like his namesake, he was nothing more than a weapon, a tool to be discarded once its usefulness has been outlived.

One of Raiden's nicknames, Jack the Ripper, is a pseudonym for an unidentified serial killer in 1888 who was active in the largely impoverished districts in and around Whitechapel, London. In this case, it was a reference to his skill and cruelty with a blade, a trait that was ingrained into him by Solidus. Just prior to their final battle, Armstrong also called Raiden "Saucy Jack," which was the penname used by the 1888 Jack the Ripper to London police at Scotland Yard after committing his second murder onwards. Another nickname of his was the White Devil, which was derived from a slur towards Caucasians originating in China. The nickname's usage in this case was a reference to Caucasians (Raiden's ethnicity) being rare in Liberia at the time of the Civil War.

Personality and traits
Due to his participation in the Liberian Civil War, Raiden was one of the few Force XXI VR subjects to possess actual combat experience. Also, because of his past as a child soldier, as well as his possessing Post Traumatic Stress Disorder, as a result, he also occasionally pushed away even people he cared about due to his being "fearful of the night." Because of this, he was outwardly cold even to people whom he personally knew, such as his then-girlfriend Rosemary. It was largely because of this cold nature, as well as his pushing people he knew away that resulted in Rosemary initially fearing that he was unfaithful to her. When he first infiltrated the Big Shell, Raiden appeared to be a young and "inexperienced" agent of a "reformed" FOXHOUND unit, occasionally prone to emotional outbursts. Throughout his mission, however, being that the memories of his past began to slowly resurface, he also began to suspect that he enjoyed killing, and reluctantly informed Rosemary as much. When the memories of his time as a child soldier began to resurface, he gained somewhat of a low opinion of himself, especially in comparison to Solid Snake's accomplishments. He also held some hero worship for Solid Snake, as part of the reason for his agreeing to partake in the Big Shell Incident to take down the terrorist leader was so he'd meet the legend face-to-face, and was initially disappointed when it seemed Snake had truly died in the Tanker Incident. Although he immensely respected Solid Snake, there were instances where it had its rough spots during the Big Shell Incident, such as when he learned that Snake and Otacon lied to him about whether they knew about the Big Shell being a great big conspiracy, as well as a remark Snake made that got him angered enough to make explosive insults about Snake, not realizing that he was in earshot, and when Snake "betrayed" Raiden at Arsenal Gear to lessen security onboard without warning him beforehand. During Liquid Ocelot's Insurrection, Raiden also viewed Snake as a father figure. Prior to finding out that Pliskin was in fact Snake, he also held some respect for Pliskin in terms of mentorship and comradery. Nonetheless, he did end up suspicious when Rosemary seemed to be praiseworthy of Pliskin.

Raiden used to smoke cigarettes at one point in his life, but had quit by the time of the Big Shell Incident. He also possessed barcode tattoos all over his body.



Raiden shared some similarities with his Cyborg Ninja predecessor, Gray Fox: both had been child soldiers who were given nicknames (and to a lesser extent, formal names) due to their brutality, they both ended up being taken from a rehab center by a group that was implied to have connections to the current organization in power (in Gray Fox's case, the CIA and the Philosophers, in Raiden's case, an NGO group and the Patriots) before being experimented in a way that was implied to also have resulted in suppressed memories, they both underwent cybernetic experimentation by the Patriots and used technologically advanced blades, and they both saved Solid Snake from a Metal Gear (Fox with REX, and Raiden with Outer Haven). Raiden was also similar to Gray Fox's adopted sister, Naomi, in that he was adopted by the same person who murdered his parents. Raiden was also similar to Kazuhira Miller, in that he bore unusual features regarding his country of origin. Raiden is the only known Cyborg Ninja to have survived, and also the only one who hasn't fought Solid Snake.

Raiden also was skilled at cleaning up messes, as he mentioned to the Colonel regarding not leaving stuff lying around at Strut C during the Big Shell Incident. He implies that he gained the skill at cleaning up from having to clean up various messes that Rosemary leaves at her house.

Raiden also had some knowledge of pop culture, as his meeting with Rosemary occurred from an argument relating to the building the titular monster climbed in the film King Kong (Rosemary claimed it was the Chrystler Building), and was at least familiar with the film Escape from New York, as he deduced the partial origin of Solid Snake's alias, Iroquois Pliskin, from that film. At one point in 2018, he told fellow Maverick member Courtney Collins that he was a huge movie buff, when she reacted with surprise that Raiden actually watched samurai films.

He also knows Spanish, as evidenced by his telling two Mexican pedestrians who spotted him "Adios, amigos!" (Spanish for "Goodbye, friends!"). In a codec conversation with Courtney, he tells Courtney that he learned Spanish while "training" with FOXHOUND.

He also seemed to understand at least some French, as he understood Mistral's last words.

Raiden's main characteristic was his long white-blond hair. Because of the length of the hair, Emma once speculated that the hair was actually a wig and that it was a badly done wig. Raiden, having overheard that comment with a directional microphone, called her via Codec to set her straight that his hair is actually real and not a wig. Similarly, his appearance also led him to being mistaken for a woman, as evidenced by James Johnson mistaking him for a female Patriot assassin before realizing his mistake by grabbing his crotch and then reacting with slight surprise that Raiden was male. As a child, this characteristic, alongside his Caucasian appearance, had him stand apart from other Liberians, whom at that time were largely African in ethnicity.

By the time of Liquid Ocelot's Insurrection, Raiden had changed considerably; the trauma of his break-up with Rose and the "miscarriage" of their unborn son, combined with rigorous training and his torture at the hands of the Patriots, changed Raiden from an inexperienced rookie to a cold and virtually emotionless soldier, who seemingly doesn't care about his own life; for instance, in his fight with Vamp in South America, he freely admitted to Vamp that he didn't fear death. Raiden's only real display of emotion occurred after the death of Big Mama; Snake told Raiden that he (Snake) has no future, while Raiden has a family; at this, Raiden grabbed Snake, shouting that he too has nothing. Nonetheless, due to his past experiences with Snake, he was completely loyal to the legendary soldier and citing his personal views about Snake by asking him to "not leave me alone." Upon discovering the truth about Rose's "marriage" to Campbell, Raiden seemed to regain some of his old self. In addition, in large part because of his experiences during the 2009 Big Shell Incident as a test subject for the S3 Plan, as well as Snake's advice in the aftermath of the S3 Plan, he also aimed to follow through with Snake's vision of people living their own lives, also believing that doing so will fully free him from being a pawn to the Patriots' proxies.

By the time of his Maverick activities between 2014 and 2018, his original style at Maverick was styled after Issatsu Tasho, killing one so others may live. As a direct result of the disastrous events in Africa, Raiden had become somewhat bloodthirsty, yet harboring a strong desire for justice. He also became somewhat cocky as well, as evidenced by, after kicking an enemy soldier into a parked black car hard enough to almost flip over the car as well as set off the car alarm, his remarking that it was "too easy" before promptly cutting up the enemy soldier. Because of his first cyborg ninja conversion, he also bore several scars near his mouth, giving his mouth an appearance similar to that of a Glasgow grin both in his human cyborg form and in his second cyborg ninja body. Because of portions of Raiden's reconstructive surgery also included the implementation of an optical implant in Raiden's right eye, his normally blue eye occasionally glowed red. Because of his earlier failure to protect the African Prime Minister, and Desperado's involvement, he also had an extremely cold outlook regarding the cyborg members of Desperado, claiming that they were nothing more than "walking vending machines" (referring to his capability of yanking specific electrolyte body parts to recharge his cyborg body after cutting them up). He even compared himself to the reaper when mentioning that they chose death when taking the job. His outlook was significantly uncaring to the extent that even his fellow Maverick PMC members were deeply disturbed by his behavior. He also had a dry sense of humor and was somewhat sarcastic during this time as well, as he responded to Boris when he asked how it felt to be flying like a bird (referring to his being carried over by the MQ-133C flying wing to Abkhazia) that it felt like "a bird strapped to a rocket."

After becoming a Cyborg Ninja, his overall strength, speed, agility, and endurance had increased to superhuman levels, allowing him to swing two Gekko with little effort by the wires and was even able to temporarily block Outer Haven. His cyborg body appears to conduct electricity or he seems to be highly resistant to it as when he is separated from his H.F Blade the lightning seems to stop. During the attack on Outer Haven, he also appeared amidst several lightning strikes that killed several FROGS. Raiden's cyborg body during this time appears to be pressurised in some manner, as shown during the two occasions in which he fights Vamp, when knives are propelled out of his torso, as well as when he disengages his visor. The exoskeleton can also bulk up to enhance the strength and speed of Raiden, similar to Solidus Snake's exoskeleton. During 2018, he often released discharges of electricity while moving. In addition, while adopting the Cyborg ninja outfit, he was strong enough to not only parry a modified Metal Gear RAY umanned unit's blade, but also to lift it up by the blade and throw the RAY a great distance, as well as agile enough to springboard across several HEMP missiles towards the RAY unit, as well as jump up to the RAY unit's blade after throwing it a great distance in a small period of time. He later pulled a similar feat with the much larger Metal Gear EXCELSUS. In both Cyborg Ninja bodies, he also has elevated pieces on his feet, near his heel portion. These act as grips for his HF blade, in the event that he attempts to use a breakdance-like maneuver to cut up enemies. His abilities were likewise improved after his second cyborgification, to the extent that he joked that he "wouldn't even need both eyes" to take down any of Desperados cyborgs if ambushed. Raiden was also capable of surviving falls large enough to kill any ordinary person, as evidenced by his falling down into the cityscape of Denver, although Boris implied that this was largely due to luck. His strength also enough for him to effortlessly pry open a gate with his bare hands. His strength, although greatly benefitting him, can also get him into big trouble, a notable instance of this was when he arrived at Solis, where he accidentially wrecked the front gate's electronic lock in order to enter the area due to believing that it was simply open, which resulted in Sunny landing him with an invoice requiring him to fully pay off the restructuring and repair costs.

By the time of 2018 he has become an adherent of the katsujinken ("sword that gives life") and issatsu tasho ("one life to save a thousand") philosophies originating in Japanese Buddhism, which justify the taking of lives in order to protect society, preserve justice, and defend the weak. His desire to protect the weak at all costs, even if it means taking lives to ensure the weak are protected, stemmed from his past as a child soldier in Liberia, and not wanting anyone else to experience the kind of childhood he had. He is also willing to break the law if he knows it is morally right, as evidenced by his decision and motives to conduct a corporate raid on World Marshal Inc.'s headquarters at Denver, Colorado.

Because of his experiences with the Patriots' AIs, he also wasn't initially trusting of sentient neuro-optical AI weapons like Bladewolf, with Raiden being bemused that Bladewolf, then the LQ-84i, in its dying sentiments, could conceive of, much less desire, freedom, as well as calling out Bladewolf for claiming that AIs never lie by claiming that the Patriots AIs did just that. However, throughout his partnership with Wolf, he began to trust him, even telling him that he is free to pursue his own destiny.

Raiden also displayed signs of mental and emotional instability and Split personality around the time he started his missions involving Desperado and during the fight with Sam in Colorado, he ends up losing control of his inner nature and his suppressed "Jack the Ripper" persona, resulting in their respective moral alignments becoming blurred. He began viewing himself as being "part of the 2%" of people who take joy in murdering enemies upon making their first kill in the battlefield. Indeed, while under this persona, he also frequently breaks out into manic laughter when killing his enemies. In addition, while undergoing this persona, he also emits a crimson aura, and also keeps the blood of his enemies on his sword.

Raiden wasn't much of a sports fan, although he had admitted that the closest he'd come to actually liking a sport is basketball.

Unconfirmed history
At some point between his meeting with Rose and his participation in the Big Shell Incident, Rose had informed Raiden that he physically resembled the British singer/actor David Bowie from the latter's youth due to his androgynous features.

Raiden's surgery following the events of Liquid Ocelot's Insurrection, where he was reunited with Rose and first met Little John, took place in a hospital in Maryland.

Behind the scenes
Of the main protagonists throughout the series (Solid Snake, Naked Snake, and Raiden), Raiden is the only one who was capable of reproducing, and also fathered a child through natural means.

Metal Gear Solid 2: Sons of Liberty
Raiden (雷電) appears as the main protagonist of Metal Gear Solid 2: Sons of Liberty. Konami kept his starring role a secret right up until the game's release in North America, even going so far as to have his Japanese voice actor swear to secrecy about the role his character will play until the game's release and to replace Raiden with Snake in teaser trailers and other preview materials (although he did appear in a few trailers, in his scuba gear, his presence was not as emphasized as the other characters). Kojima personally requested the development of Raiden as a means to develop Solid Snake from a third-person perspective. In the original script, Raiden's voice was also to have been replaced by Solid Snake's prior to his unmasking, should the Plant Chapter have been played through first. The presence of Raiden in the game was announced to the Japanese press on the same day as the game's release in North America. Early concepts for Raiden originally depicted him with dark hair, whereas Rosemary would have been depicted as a blonde, although the hair colors were switched around by the final version. The script included in The Document of Metal Gear Solid 2 indicated that Raiden's hair color was changed prior to the script's finalization, while Rosemary retained the original blonde hair by the time the script was finalized.

Following the release of Metal Gear Solid 2, Raiden was met with a mixed reaction from fans of the series. Although Raiden himself was quite popular with the Japanese fandom as a result of his appearance, the International fandom had negative reception regarding the character, with some such as writer James Newman even comparing him to the Star Wars prequel trilogy character Jar Jar Binks in terms of poor reception. Much of the negative response was due largely to his apparent naive attitude, androgynous appearance as well as acting as the protagonist over Snake. In addition, the localization of the game also resulted in several fans critiquing Raiden for his high-pitched voice, which was described as "whiney." In the Japanese version, however, Raiden actually spoke with a deep bass voice. In addition, Quinton Flynn admitted in an interview with The Gaming Liberty that he based Raiden's English voice on a previous voice acting role he did under the suggestion of casting director Kris Zimmerman, whom he had previously worked with. However, director Hideo Kojima has stated in interviews that he was introduced primarily to attract new fans to the game so that he could ask questions that a veteran like Snake wouldn't ask, so as to avoid treating Snake like a rookie, and to make Snake appear more impressive as a character, an idea strongly defended by some fans. Kojima has also explicitly stated that Raiden is his favorite character in Metal Gear Solid 2, a view that was also shared by Flynn. Raiden's concept as effectively being a third-person witness to Solid Snake's exploits was likewise inspired by the character Watson from the detective franchise Sherlock Holmes.

According to character designer Yoji Shinkawa in the featurette The Making of Metal Gear Solid 2, the primary reason why Raiden is designed as a bishonen (a "pretty boy") is because a fan letter stated that the addresser in question did not want to "play a story with an old man." Kojima also mentions similar reasons in the documentary Metal Gear Saga Vol. 1.

The twist that Raiden was not Snake was admitted by Kojima to have been inspired by the plot twist of Terminator 2: Judgment Day where the titular character played by Arnold Schwarzenegger was not a villain in that movie.

Raiden's real name Jack (ジャック) is based on one of the main characters from the movie Titanic, along with his girlfriend Rose. Like Solidus Snake and Fortune, Raiden's other name is also that of a playing card - King, Queen, and Jack, respectively.

Depending on whether the player trains to swim in the Deep Sea Dock or not, Raiden's response to the Colonel when given the order to swim through the flooded Shell 2 Core will be different. If the player failed to do so, he will mention that underwater operations wasn't covered in VR training.

In the original gameplan of Metal Gear Solid 2, Raiden was to have had false memories of his father, in which he was apparently killed in a hunting accident. Raiden's "father" would also have resembled Solidus Snake.

In the novelization, Fortune's reference to Raiden's time as a child soldier in Liberia was further emphasized, where Raiden thought to himself "Fires of hell. Could she mean Liberia? The civil war? How could she know about that?"

For most of the game's development, Raiden’s name was written in katakana as ライデン or literally "Raiden." After 9/11, Raiden's name began to be written in kanji as 雷電. "Since the story resembled 911 closely, and some people said ‘Raiden’ reminds them of ‘Bin Laden.’"

- Hideo Kojima

The name was altered because in Japanese, “Laden” is written as ラーディン.

Raiden's naked CG character model (used during the initial infiltration of Arsenal Gear) actually possesses no genitalia. It can be assumed that the developers chose not to model the character in such detail given that the player would not notice this feature under normal circumstances. As such, the model is not intended to fully represent Raiden's physical characteristics, as supported by lines of dialogue from various soldiers, in regards to the presence and size of his genitalia. However, performing certain actions will allow the player to briefly glimpse this choice of design.Initially he was american-chinese but has been converted into american-liberian.

Metal Gear Solid 2: Substance
In VR training, he is features as three separate characters:

RAIDEN - This is Raiden in his normal attire.

RAIDEN  - This Raiden, taking upon the appearance of Gray Fox, is armed with the H.F Blade. It's interesting to note that whilst playing as this character, Raiden shares the same face as Frank Jaeger in Metal Gear Solid: The Twin Snakes. Also when the player equips the night vision goggles or thermal goggles, the visor is shut taking on the full appearance.

RAIDEN X - Naked Raiden as he appeared initially on board Arsenal Gear before re-obtaining his gear from Snake. Whilst playing as this character, Raiden's actions are limited.

Metal Gear Solid 3: Snake Eater
Metal Gear Solid 3 makes use of Raiden's character as well as his appearance. Selecting the option "I like MGS2!" before starting a new game, triggers a change in the opening, in which Naked Snake (also named Jack) wears a mask that looks identical to Raiden's face, to conceal his identity from the gunship crew (although it is implied in-story to be based on the likeness of GRU major Ivan Raidenovitch Raikov). The mask was created primarily as an excuse to allow people who liked Raiden in MGS2 to technically play as him, owing to his popularity in Japan. Additionally, the oxygen mask that Snake wears during the HALO jump bears an intentional resemblance to the diving mask that Raiden wears in the opening of Metal Gear Solid 2. Likewise, the reasons for his creation, as well as the fan controversy that ensued, were also given subtle references in the game via two radio conversations, both involving the character Major Zero. The first conversation, gained when calling Zero while wearing the mask during the Virtuous Mission, will have Zero comment that he, "for some reason, doesn't like it," in response to Naked Snake's reason that wearing the mask seemed "nostalgic." The second conversation, unlocked after completing the Raikov disguise, has Major Zero commenting that the disguise "is irritating [Zero] already." to which Snake retorts that the disguise "should make [Naked Snake] more popular." Some traits of Raiden were also incorporated into Snake as well, including having the same real name, as well as a significant other also referring to him as Jack despite being ordered to go by his codename (Rosemary in Raiden's case and The Boss in Naked Snake's case. Coincidentially, both The Boss and Rosemary were also voiced by the same voice actor in the Japanese versions).

Later in the game, Major Raikov, (who bears an intentional resemblance to Raiden) must be neutralized and his uniform stolen in order to infiltrate the west wing of Groznyj Grad. "Ivan" is the Russian equivalent of "John," for which "Jack" is often used as a nickname in English. Raiden himself makes a cameo appearance as a poster in the locker that Naked Snake places Raikov inside upon stripping him of his uniform, as a subtle reference to their similar physical appearances.

In the Metal Gear Solid 4 Directors trailer, Raiden makes a parody appearance along with Snake, who is dressed to look like Sam Fisher, the main character in Splinter Cell. The trailer depicts them fighting over who will be the main character of Metal Gear Solid 4. Snake wins the fight easily due to Raiden having terrible CQC skills, sitting in the "Main Character" chair, signalling a chime. But just as Snake leaves and before the credits roll, Raiden is seen eyeing up the chair, and as the screen fades to black, the same chime is heard. However, Raiden is not a playable character in Metal Gear Solid 4.

Raiden has a major role in one of the Secret Theater shorts made by Kojima Productions for their website, and included in Metal Gear Solid 3: Subsistence. Entitled Metal Gear Raiden: Snake Eraser, Raiden (voiced by Charlie Schlatter, who voiced Raikov in the main game), motivated by Rose's comment about changing the future, attempts to "erase" Solid Snake by traveling back in time in a Terminator-like fashion and attempting to assassinate Naked Snake, all ending in humorous failure. One of his failures also had him encountering Colonel Volgin in the prison, referring to his similar appearance to Raikov. After deciding not to kill Naked Snake, he went back to the events of the Zanzibar Land Disturbance (complete with MSX2 graphics) to kill Solid Snake himself, ending in similar failure, where, ironically, he is stopped by his original target, Big Boss. In the ending, he accepts that he can't change the past, although he does hope to get a starring role in another Metal Gear game (which he does). Besides Snake Eraser and the Director's trailer, he also might have had a brief cameo near the end of the film Payback, where he ends up run over by the Shagohod. According to Kojima, he and the other Metal Gear staff personally liked Raiden, but they effectively made him the "clown" of the secret theatre films largely because they realize most of the fans outside Japan did not like him.

Metal Gear: Ghost Babel
Raiden does not appear in the main story, but he is briefly referenced by his real name, Jack, in the special ending after the player managed to complete 40 VR missions, where he was apparently being trained with various VR missions relating to Solid Snake's exploits in the Galuade Incident, presumably to make Raiden more powerful than Snake was during Galuade's fall. Because Ghost Babel was developed and released prior to Metal Gear Solid 2, this technically was Raiden's first appearance in the series.

Metal Gear Solid Mobile
After completing Metal Gear Solid Mobile, revealed to be a VR mission, Solid Snake is declared a failed test subject and has his memories erased, and a pair of mysterious voices discuss a second test subject, "Jack", wondering if he can do better. After completing all the Special Mission stages in the previously released Metal Gear: Ghost Babel, a mysterious person named No. 4 makes a cryptic reference to the unknown participant taking part in the VR missions, referring to the participant as "Jack."

Metal Gear Solid: Portable Ops Plus
In Portable Ops Plus, Raiden becomes playable in Infinity Mission mode after beating the game on Hard mode.

In the game, Raiden appears as he does in Metal Gear Solid 2. He is not able to use his acrobatic kick from Metal Gear Solid 2, due to most of the character models (exempting Cunningham) reusing Naked Snake's unarmed combat stances, and instead is able only to ram at opponents like any other soldier, and like the Arsenal Tengu, he is equipped with a blade so he only has three free item slots, but an advantage in comparison to the Tengu ops is that Raiden perform unending combos with his blade which gives him the chance not to get discovered while slashing enemies. His use of a sword is also referenced by Roy Campbell upon Raiden's recruitment, stating that a new soldier joined who wields a katana. Added to this is that Raiden, unlike Naked Snake or Old Snake, has the Athlete ability which makes him run faster than regular soldiers. He shares this career with his look-alike, Raikov. However, on the downside, he possesses less stamina and health points which makes him vulnerable when he is surrounded by enemies. Overall, he possesses similar stats to Old Snake and Naked Snake.

In stark contrast to Raiden's lack of CQC skills in the 2005 Director's Trailer for MGS4 included on Subsistence, he is shown in this game to have an S2 rank in CQC, the highest rank.

"A member of FOXHOUND, with extensive VR mission training. Received code name "Raiden" while infiltrating the Big Shell, an ocean cleanup facility occupied by terrorists. Raised as a soldier from childhood, and haunted by memories of his past, his real name is Jack."

- Official description in Metal Gear Solid: Portable Ops Plus

Metal Gear Solid 4: Guns of the Patriots
Raiden was confirmed to make a reappearance in Metal Gear Solid 4 during its development. In an interview with 1UP, called Saving Private Raiden, Kojima elaborated that he's not a playable character, and also stated that it was the actual Raiden and not someone who looks like Raiden. In addition, he also assured them that when the players play the game, they'll like Raiden a lot more than in MGS2. Raiden's never-used sidearm in Metal Gear Solid 4 is the classic Mk23. It is visible on the Medicom Action Figure based on the designs by Yoji Shinkawa, and usable when playing as Raiden in Metal Gear Online.

Raiden's line to Vamp when questioned about his "immortality," "I Just Don't Fear Death!", was also the name of a trophy achievement in the trophy patch for the game, unlocked when the player uses the corpse camo to cause an alert.

Raiden was mentioned to have gained information from GW relating to Big Boss's location, which explained how the Paradise Lost Army managed to locate and steal his body. Whether his possessing the information had anything to do with his cerebral network of nanomachines acting as a backup system for GW or not was never explained.

Concept artworks for Liquid Ocelot included sketches where Ocelot was ambushed by a mysterious figure, and the figure manages to cut Ocelot's right forearm off, a'la MGS. The figure's sihlouette and the figure brandishing a sword implied that the figure was Raiden. Similarly, some concept artworks for Raiden himself also had him wearing an outfit superficially resembling his Skull Suit with a facemask covering all but his upper face, as well as his carrying a then-infantile Sunny.

Metal Gear Online
Raiden is a special character downloadable from the SCENE expansion pack along with Vamp.

Raiden the White-blooded Scout, can fall from any height without damage and jump on ledges that would normally require a boost, and has no nanomachines. He handles a High Frequency Blade, operable in lethal and non-lethal mode, which allows him to deflect frontal attacks. His other unique weapons are the Mk.23 pistol and the Throwing Knife. When his Visor is closed, he can see all traps in the map. Instead of the usual CQC three-hit combo, he instead starts a spin kick which continues as long as the user keeps tapping R1. When pressing the jump back button, Raiden, does backwards handstands instead of jumping backwards (Raiden can get shot during these back handstands). He is also equipped with CQC 2 and a throat-slitting ability, along with a running ability higher than Runner 3. The only downside is that, as he does not possess nanomachines at all, he is incapable of performing an SOP link. If tranquilized, he'll sometimes say "Rose..."

When playing as Raiden, he does a pose similar to that of Gray Fox in concept art for Metal Gear Solid. This can be seen after taking a large fall. He does a similar pose in Metal Gear Solid 4 itself during Act 2, shortly after defeating several Gekko.

Despite being a cyborg, Raiden could end up drowning.

Metal Gear Rising: Revengeance
"A unique cyborg frame, upgraded to aid Raiden in his fight against Sam and Desperado. Equipped with Blade Mode and able to absorb fuel-cell electrolytes from any high-frequency blade, it unfortunately lacks any kind of self-repair unit, meaning Raiden must manually extract repair material from his foes to recover from damage."

Metal Gear Rising: Revengeance is the second game in which Raiden is the primary player character, although this time the player takes control of Raiden in his Cyborg Ninja appearance. According to Kojima, he planned for the story to be about Gray Fox, although he let them do Raiden as the staff wanted to do Raiden, and he wanted a producing role instead of a directing role, anyway, something that could not happen if Gray Fox was the main character. The story for the game, when it titled Metal Gear Solid: Rising, was originally going to cover the events that occur between Metal Gear Solid 2 and Metal Gear Solid 4, and would have focused on how Raiden became the character he is during Liquid Ocelot's Insurrection. However, at some point, the story was moved to taking place years after the events of Metal Gear Solid 4. The decision to move the time period was met with a large degree of controversy, as several fans felt that it cheapened the ending of Metal Gear Solid 4, in particular Raiden's final scene. A podcast, however, addressed this issue and stated that the game would explain why Raiden is back on the battlefield despite the implications of Metal Gear Solid 4 's ending. Raiden's Japanese voice actor during this game was originally planned to be Toshiyuki Morikawa instead of his regular voice actor, Kenyū Horiuchi. However, they eventually got the latter to reprise his role when Metal Gear Solid: Rising was revamped into Metal Gear Rising: Revengeance. Similarly, Quinton Flynn, around the same time, tweeted that he wasn't approached to reprise the character in Metal Gear Solid: Rising, implying that Raiden would have a different voice actor in the English version as well, although Flynn eventually reprised the role when the game was revamped into Metal Gear Rising: Revengeance.

The game employs a more action-based style of gameplay based around a concept called "zan-datsu" ("cut and take"), although the stealth gameplay of the previous games will still be present. The gameplay strives to allow the player to replicate the same kind of feats that Raiden performs in Metal Gear Solid 4.

The original render of Raiden from the game's reveal at E3 2009 showed him with a brown eye and a pale complexion. The eye color was rectified in a promotional render released several months later via the online game Metal Gear Solid: Piece Walker. While Raiden's hair was loose in Metal Gear Solid 4, in Rising it is swept back.

Although Raiden's involvement in the Liberian Civil War was stated as early as his first appearance in Metal Gear Solid 2, it wasn't until Metal Gear Rising: Revengeance that it was explicitly stated that Liberia was his birthplace.

In the artwork for Rising and Revengeance, Raiden had a navy-blue bandage over his left eye as a makeshift eyepatch. It is unknown what caused him to adopt it, although a teaser image of a medical report on the Revengeance site implies that he got retinal damage from injuries that resulted in several lacerations and the amputation of a currently redacted body part. Another letter regarding the retrieval of Raiden's arm further implies that the amputated body part was in fact his left arm. The "Arm" trailer also implies that he received an optical implant. Likewise, the "Eye" trailer mentioned that the damage to Raiden's left eye was irreparable due to the optical nerve being completely destroyed, resulting in it having to be removed.

In a leaked casting call for Metal Gear Rising, they requested for at least four live actors to portray characters for a trailer. Raiden, as well as his younger self (identified as Jack in the casting call). With Raiden, they requested the actor to be a male caucasian, within the 23-25 year range, possessing longish blond hair, an athletic build, no scars yet possessing tattoos, plus if possible some hand to hand combat/swordplay experience as well as a slight Greek or Italian accent. With Jack, they requested for the actor to be within the 8-12 year range, have blond wavy hair and blue eyes, being athletic, have no scars on the arms, possess dramatic acting, and if possible possess a slight Greek or Italian accent.

In the Arm, Eye, and Sword trailers, the scene shifts halfway through to Raiden undergoing some aspects of his harsh childhood under a man whose voice and appearance resembles Solidus Snake. The Metal Gear Solid Facebook page later confirmed that those scenes in the trailers were meant to show Raiden's training under Solidus.

Kojima revealed when unveiling the screenshots of the then-in-development demo for Rising that the arm he sent to various groups belonged to "white raiden", and that Raiden's cyborg form seen on the promotional spots and main menu was "black raiden." He later clarified that "white raiden" was Raiden's armor from Metal Gear Solid 4, and also stated that it was playable. He also implied in another Twitter account that Raiden's pre-cyborg self during the events of Metal Gear Solid 2, named Old Raiden/Blue Raiden, might also be playable. In addition, a Kojima Productions staff member, when addressing a question frequently asked about the scene at the end of the E3 Trailer, stated that the scene with Raiden in an alternate armor actually took place very early in the game, and that the armor in question was actually a wearable version of his Metal Gear Solid 4 armor, having gained a more normal cybernetic body by the end of Metal Gear Solid 4.

One of the ways he kills his enemies is based on Void Ninja Yoshimitsu's Flea Stance from Tekken 3 and later games. in these games, Yoshimitsu is able to crouch on his sword, and like Raiden, he is a cybernetic ninja due to having a mechanical arm that rapidly rotates for his Dragonfly Stance.

"Traditional garb for Mexican folk musicians, purchased by Raiden at a souvenir shop south of the border in a misguided attempt to blend in with the locals."

- Mariachi Uniform description in Metal Gear Rising: Revengeance

On the week of June 12, during Kojima's Metal Gear Rising demonstration in Mexico, Raiden's CGI model for the demo's menu was slightly modified to include a sombrero and cloak as a hint as to what exclusives the Latin American version will have. Raiden's sombrero outfit later made an appearance twice in the TGS 2012 trailer: The first time is seen briefly where he is driving a black car, and the second is nearing the end of the trailer: Two people (implied to be Mexicans/Latin Americans and confirmed to be Mexicans in the official PlayStation Blog) find Raiden on the other side of the road attempting to enter a manhole, while holding up a sewer grate shortly after his car left. Raiden then looks up and says "Adios, amigos." (Spanish for, "Goodbye, friends.") before departing and closing the grate, also leaving his sombrero behind. Raiden's use of the outfit, identified as a Mariachi outfit, was later explained in the MGRR Mastiff boot camp trailer at Santa Monica, where it was stated that Raiden bought the outfit in a mistaken impression that it would help him blend in with the populace while undergoing his mission into Mexico.

The 166th session of the KP Report Podcast also revealed that Raiden was the only character in the game to be designed by Yoji Shinkawa.

In the trailer for the Battle against RAY, Raiden is revealed to have a different HUD based on the one seen in MGS4, because he was using a modified version of his original cyborg body, as well as the battle taking place before his duel with Sam. As such he can't regenerate his health via zan-datsu, but he still can heal by getting health pickups like how the player does in MGS4.

"A custom body equipped with self-recovery nano-paste and electrolyte packs. The large amount of cyborg healing and regeneration features allow the white custom body to excel in a force support role. The white armor reminds one of medical support personnel's uniforms."

- Custom Cyborg Body (White Armor) description from Metal Gear Rising: Revengeance

"A custom body equipped with a full compliment of grenades. Created as a body intended to serve in a mid-range fire support role, the wide variety and number of equipped grenades make this body particularly deadly. Its fiery red color betrays its status as a grenade throwing death machine."

- Custom Cyborg Body (Inferno Armor) description from Metal Gear Rising: Revengeance

"With a multipurpose RPG launcher and portable SAM missiles built in, this green custom cyborg body harkens back to the outdoor BDUs worn by the infantry soldiers of yore. This body excels against UAVs, tanks, attack helicopters, and other anti-infantry weapon systems due to its extra munitions."

- Custom Cyborg Body (Commando Armor) description from Metal Gear Rising: Revengeance

"A chassis patterned after Gray Fox's body circa the Shadow Moses incident, but functionally equivalent to recent cyborg bodies. Though it was termed an "exoskeleton" in those days before the advent of modern cyborg technology, it could not be taken on and off at will."

- Gray Fox description from Metal Gear Rising: Revengeance

"A recreation of the cyborg body used by Raiden in the Guns of the Patriots incident. Functionally obsolete and boasting an obviously unnatural jaw, its battlefield potential is extremely limited."

- Original Cyborg Body description in Metal Gear Rising: Revengeance

On November 2012, it was unveiled that people who preordered Rising would get an exclusive code that allowed Raiden to use a custom cyborg body modeled after the exoskeleton used by Gray Fox. Later, on December 2012, both the Rising website and metalgearsolidtv.com (a streaming site dedicated to Metal Gear Solid-related news and videos) revealed that, in addition to the Gray Fox download, the MGS4 armor, and possibly MGS2-era Raiden, Raiden will also have at least three unlockable armors: The White Armor, which has no relation to his MGS4-era armor despite having the same name, and which possesses on a special medical care system. Because of the similar name, Kojima Productions also gave it the alternate name of Medical Raiden. Specifically, this cyborg body was modified to focus on support for allies in the battlefield, which includes an increased capacity of items relating to cyborg treatment and supplies for repairs; the Inferno armor, colored crimson and possessing a special attack system. Specifically, he was modified to allow for him to utilize mid-range attacks via throwing grenades, allowing him to carry an increased supply of various grenade types; and the Command armor, colored yellow-green and possessing a traditional fighting system. Specifically, he was modified to take into account the possibility of fighting various pair warfare drones, tanks, and attack choppers by possessing an increased supply of surface-to-air guided missile warheads, as well as rocket grenade launchers of both type instrument and multi-purpose capabilities. The exclusive armors can be downloaded via purchasing codes from KonamiStyle, Tsutaya, and Geo, respectively. However, for the European versions, the White armor, Inferno Armor, and Commando Armor will be included as a free download in the EU collector's edition from Zavvi, the GAME preorder, and preorders from other retailers, respectively and in America, the Inferno and White Armor will also be included with Rising if pre-ordered from Amazon.com. and Best Buy, respectively. The Japanese site later unveiled a trailer for Rising that showed various DLC skins, including the aforementioned Gray Fox skin and the three bonus colors, and also revealed that Japanese players can also get a custom body based on Raiden's original cyborg body in Metal Gear Solid 4 via a Rising trial on the 18th, by making a review upon playing the demo and posting it on either Facebook or Twitter and then receiving a download code. It is currently unknown whether America will get it as well, although the official site implied that it will be released in areas outside Japan at a future date. Another update on the official site indicated that the MGS4 Raiden skin will be preorderable from Amazon for the Japanese release of Rising. On February 15, 2013, the official Metal Gear Solid and Metal Gear Rising facebook pages posted that the MGS4 Raiden will be available as a DLC download for the XBLive and PSN networks for releases outside Japan on February 19 (the release date for the American release of Rising), and also specified that it's not a preorder bonus.

In the same trailer, each of the skins is shown fighting against enemies in a similar manner to how they fought in at least one scene from their original appearances. The Gray Fox skin was shown killing Desperado Cyborgs in a manner similar to a scene in Metal Gear Solid, where where he cuts up several terrified Genome Soldiers, while MGS4 Raiden was shown taking on some Desperado Gekko, a reference to his first on-screen appearance in Metal Gear Solid 4, where he took on, and destroyed several Gekko.

On January 14, 2012, nearing 5:00 PST, a new trailer was released that showed Raiden's Jack the Ripper persona. The trailer included an internal monologue by Raiden, or rather, Jack, that wasn't included in the final game: Specifically, Jack mentions that he had read a study that indicated that only one out of fifty people could kill without hesitation, before declaring himself a "two-percenter." Jack then mentions that most soldiers couldn't handle the violent deaths of enemies, but then stated that he likes the deaths a lot, and implies that this was due to it being ingrained on him since early childhood. Jack then recollects the abuse and threats at gunpoint during childhood before he, "next thing he knows," got off on slicing foes to shreds. Raiden then states that he's going to enjoy the ensuing carnage before being ambushed by the DPD cops/Desperado/World Marshal soldiers. The lines themselves, however, were incorporated into optional Codec conversations for Chapter R-04. Jack's claim of being a "two-percenter" was a subtle reference to the term "one-percenter," referring to the concept of the 1% of America's richest people.

In the Location Trailer released alongside the Zan-Datsu & Custom Body Trailers, a part of it showed Raiden wielding Mistral's Etrangers, suggesting that he could wield the weapons of rival cyborgs he's beaten. This is later confirmed in the Unique Weapons trailer, which also implies that Raiden received copies of these weapons after they were developed by Doktor after he carefully analyzed their combat data.

Raiden's business suit from the prologue was also implied in one of his cards in Metal Gear Solid: Social Ops to be an unlockable skin, similar to Snake's suit in Metal Gear Solid 4.

Three recolors of Raiden's cyborg body were also issued as figures for Play Arts KAI as part of the Battle Raiden series, colored Red, Blue, and Yellow. The armors were also included in-game as unlockables.

Kojima, regarding the release trailer on February 19, initially intended to use voice clips for Raiden from Metal Gear Solid 2, although he decided against it, as he didn't want to inflict kill-joy on the trailer.

On March 4, Kojima compared Raiden's characterization to that of Action film series hero John Rambo, citing that both characters fight despite being peaceful in nature.

"A cyborg frame with yellow artificial musculature that consumes minimal fuel-cell energy and is highly efficient at absorbing electrolytes from foes."

"A cyborg frame with blue artificial musculature that is insufficient at absorbing electrolytes from foes and somewhat lacking in power, but boasts high defensive ability and consumes minimal fuel-cell energy."

- Custom Cyborg Body (Blue) description in Metal Gear Rising: Revengeance

"A cyborg frame with red artificial musculature that offers minimal defense and consumes considerable fuel-cell energy, but is highly effective at absorbing electrolytes from foes."

- Custom Cyborg Body (Red) description in Metal Gear Rising: Revengeance

"A cyborg frame patterned in the style of Desperado Enforcement contractors. The performances of this frame are identical to those of the normal Custom Cyborg Body."

Metal Gear Solid: Social Ops
Raiden has a few cards depicting his original Metal Gear Solid 2 appearance, his HD artwork for the same game, his Metal Gear Solid 4 appearance, and his various appearances in Metal Gear Rising: Revengeance.

Other appearances
Raiden is a secret character in Evolution Skateboarding. To play as Raiden, the player must beat the game 100%, collecting all coins with character Mark Appleyard.

Raiden's likeness also appears in other games:
 * Artwork of Snake from Metal Gear Acid show two soldiers in the background; one of them has the same Skull Suit and mask that Raiden wore during the Big Shell Incident.
 * Raiden, in the Skull Suit, is featured as a sticker in Super Smash Bros. Brawl. The sticker increases the character's Direct Special attacks by 14, alluding to Raiden's preferred weaponry being blades.
 * A costume available to download for LittleBigPlanet allows the Sackboys to dress up as the MGS4 Cyborg Raiden.
 * In Assassin's Creed: Brotherhood, Raiden's MGS4 cyborg ninja outfit can be unlocked by achieving at least a bronze metal in each of the simulations in the Virtual Training Program in the Animus 2.0.
 * The Metal Gear Rising incarnation of Raiden appears as a playable character in the crossover fighting game PlayStation All-Stars Battle Royale. An alternate unlockable skin is available to change his appearance to that of Raiden in Metal Gear Solid 4 and another downloadable alternate to change his appearance to that of Metal Gear Solid 2. His moves revolve around speed and the use of his HF Blade. Raiden's level one super is the hand stand spin-kick, level two an approximation of "Blade Mode", and level 3 has the enemies hide in boxes while Raiden slashes them apart. His rival in the game is Cole MacGrath from the InFamous series.His level 3 is called Boxed In.

A Play Arts Kai figurine of Raiden based on his appearance in Metal Gear Rising is in the works. The final color model was unveiled on the Metal Gear Solid Facebook page at 5:58 PM on August 9, 2012.

Raiden, as his Cyborg Ninja self, appeared as a participant in the Konami-sponsored event E3 Battle, where he defeated Krystal from ''Hard Corps. Uprising'' in the first round, largely due to his cybernetics, and in spite of Krystal's many armaments. He then faced off against and defeated Devil Zukin from Dance Dance Revolution 3rd mix in the second round. Raiden proceeded to fight against Pyramid Head from Silent Hill in the third round, defeating it. Raiden then faced off against and defeated Revolver Ocelot in the fourth round. Raiden then fought and lost to Naked Snake in the semifinals.

Raiden (in cyborg form) also made a guest appearance in an episode for the low-budget comedic video game parody web-series "Mega64." In it, Raiden went to the unemployment office at 4:00 PM on a Tuesday (16:00 hours), having been unemployed from Corporate America for four years due to the bad economy, where his unemployment manager attempts to help him get a job, but all the job offers he gets end up going horribly wrong, including an entertainer for children's birthday parties (accidentally destroyed the table and moon bounce while attempting to cut the cake bushido-style during a birthday party for a five year old kid named Leonard); plumber (wrecked Ricky's toilet further while attempting to use his sword as a plunger at 8:00 AM (08:00 hours) on Friday); Gourmet chef (overdid the Japanese Steak House-style cutting of Red and Green peppers at a Gourmet Restaurant at 7:00 PM (19:00 hours) on a Friday, causing the patrons of a Gourmet Restaurant to lose their appetite and be covered in mowed down pieces of pepper); Professional Dog Walker (accidentally electrocuted the dogs to serious injury when attempting to restrain them); Town crier (mostly rang bells to an at best ignored response from the townspeople while not declaring anything); implied professional skateboarder ("Ladies love skateboarders"; Raiden attempted to do a trick, but fumbled, causing his skateboard to go flying into a parkgoer's meal); Breakdancer (attempted a breakdance move, but his legs kept spinning around apparently due to a malfunction); and artist (did a picture of a cupid, only to be told by the guy nearby that his artwork sucked). Eventually he settles for "cybernetic private military security soldier" as his last chance at a job where he was met with implied success. The same unemployment officer also helped Jehuty from Zone of the Enders get a job (starting with Children's Birthday Party Entertainer, just as he suggested to Raiden beforehand), although he spent most of his time terrorizing the neighborhood as the episode ended. Raiden, or rather Jack as he is identified in throughout the skit, does not have any dialogue in the skit. Said episode later aired as part of the Konami Pre-E3 show. According to the creators, they were specifically tasked with creating the episode by Hideo Kojima himself.

"RAIDEN FIRST APPEARED IN Metal Gear Solid 2: Sons of Liberty (2001) Former child soldier turned cybernetic super-soldier. Also goes by the name Jack the Ripper."
