Revolver Ocelot

Revolver Ocelot, real name Adamska (Russian: Адамска), and also known as ADAM, Shalashaska (Russian: Шалашаска), or simply Ocelot (Russian: Оцелот), was a former FOXHOUND operative and an agent of the Patriots. A master of interrogation and a formidable gunfighter who was often referred to as a "ricochet genius," Ocelot is best known as the man who was personally acquainted with all four members of the Snake family: serving as the right-hand man for both Liquid Snake and Solidus Snake, maintaining a friendly rivalry with Big Boss, and being a nemesis to Solid Snake. Ocelot specialized in infiltrations of a different nature than Solid Snake and Big Boss, often acting as a double agent, or even a triple agent, serving multiple interests in the same situation.

Ocelot was often known for his affinity for Spaghetti Westerns, as evidenced by his choice of weapon and his clothing, duster and spurs, the traditional garb of cowboys. Ocelot's weapon of choice was the Colt Single Action Army Revolver, which he described as "the greatest handgun ever made."

Early life and career
Ocelot was born during the Allied invasion of Normandy, France, on June 6, 1944 as Adamska, the son of The Boss (The Joy) and The Sorrow. The Joy was wounded during childbirth in the middle of the battlefield, forcing her to give birth via cesarean section and the resulting operation gave her a snake-shaped scar on her torso. Shortly after birth, Adamska was taken from his parents by agents of the Philosophers. Adamska (under the codename ADAM) briefly worked for the NSA as a codebreaker, but (along with an NSA colleague) defected to the Soviet Union in September 1960. There, he served under Colonel Volgin's command of GRU while secretly a sleeper agent of both the KGB and the CIA, proxy organizations of the Russian and American branches of the Philosophers, respectively. Because of his heritage, he was given preferential treatment as a Spetsnaz GRU agent and was even promoted to Major of his own personal unit. In 1962, The Boss assassinated The Sorrow because of the Philosophers' threat that Ocelot (their son) would die if both survived, ensuring that only one of them would return home alive.

In 1964, Ocelot (under Volgin's orders) had arrived at Rassvet with his Ocelot Unit to capture Dr. Nikolai Stephanovich Sokolov. He ambushed the KGB operatives stationed at the area and killed them, although he implied that he did not like having to do so, as they were comrades. Surrounding them with the Ocelot Unit after realizing that Naked Snake, the man leading Sokolov out was not The Boss, he attempted to kill Snake by using a Middle Eastern technique that involved ejecting the first bullet by hand, but his gun jammed at the last moment, resulting in Ocelot and his entire unit being defeated. Snake then suggested that Ocelot should use revolvers, due to his fighting style, before the latter passed out. After regaining consciousness, he boarded Volgin's Hind A while they were airlifting the Shagohod prototype to Groznyj Grad, although he also attempted to stop Volgin when Volgin decided, as the Sokolov research facility no longer served of any use to him, he might as well test one of the Davy Crocketts that he received from The Boss, and could only watch in horror after Volgin launched the Davy Crockett.

One week later, Ocelot was ordered by the CIA to aid Snake in his mission to destroy the Cobra Unit and the Shagohod, and to kill The Boss, while also retrieving the Philosophers' Legacy for the American branch of the Philosophers. However, before Ocelot could meet up with Snake, a Chinese spy posing as EVA, pretended to help Snake in his mission while secretly plotting to take the Philosophers' Legacy herself for the Philosophers in China. Ocelot decided to keep his identity as ADAM a secret and aided Snake covertly. Throughout the mission, Ocelot and Snake shared a mutual rivalry and fought on several occasions. During the fight between Snake and Colonel Volgin, Ocelot was ordered to shoot Snake. However, Ocelot refused, instead throwing items down to Snake to use against Volgin. This alluded to Ocelot's admiration for Naked Snake, although he explained that he did it because he had made a promise to The Boss. After the mission's success, the Chief Director of the KGB contacted Ocelot, where the latter mentioned that "Khrushchev is finished," and that the KGB's time had finally arrived. Shortly thereafter, Ocelot secretly made a call to the DCI. Their conversation revealed that the CIA had only acquired half of the Legacy, and it was assumed that the KGB possessed the other half.

During Operation Snake Eater, Ocelot witnessed Colonel Volgin's brutal torture of Naked Snake after he was captured while infiltrating Groznyj Grad. Though Ocelot was initially opposed to the practice, he later praised the effectiveness of torture, calling it "the ultimate form of expression," Ocelot started to research it after Operation Snake Eater, eventually becoming an expert in the field. At some later point, Ocelot eventually recovered the other half of the Legacy but kept it for himself.

In 1970, Ocelot became dissatisfied with the American Philosophers' bickering, which had pitted the CIA against the Pentagon for control of the Philosophers' Legacy. Because of this, Ocelot took advantage of the internal sitation while a takeover on the San Hieronymo Peninsula took place. After Big Boss (Naked Snake) foiled Gene's plan to have a nuclear missile hit Langley and the Pentagon, Ocelot secured the other half of the Legacy and (under the partnership of an unknown conspirator) assassinated the DCI in a manner that was indistinguishable from suicide, hoping to free the country from the Philosophers and attain the entire Legacy (as well, as the complete list with the identities of the Philosopher members). Ocelot planned to break his ties with his benefactor, until the mysterious man revealed battle data on the Perfect Soldier Project and introduced the concept of "genomes" to him. Ocelot, intrigued, then agreed to join him in the formation of "the Patriots." However, he only did this under the condition that Big Boss be allowed to join them as well.

Les Enfants Terribles
Ocelot's request was granted when Zero recruited Big Boss, along with Sigint, Para-Medic, and EVA, to found their new organization. The Patriots' dream was to shape the world into one which The Boss had envisioned, one which would once more be "whole" again. However, Zero's interpretation of her will greatly differed from that of Big Boss, which would eventually lead to their fall out. Big Boss had been raised to a being of Christ-like reverence, but he resented being treated as a puppet for the Patriots' goals. Unbeknownst to Big Boss, Para-Medic (Dr. Clark) had retrieved a sample of his DNA while he had been in a coma, and the Patriots began work on developing a clone in order to keep their "messiah" alive. In 1972, EVA agreed to serve as the surrogate mother for Solid Snake and Liquid Snake. However, Big Boss did not agree to this plan, after finding out this information for himself, and left the group to form his own mercenary army, in opposition to Zero and his Patriots.

Later career
Ocelot continued his life as a spy and agent for the newly formed Patriots (although he secretly resented its new policies). While in the Spetsnaz GRU, he participated in the Soviet invasion of Afghanistan. It was during this time that he became infamous amongst the mujahideen as a sadist, for which they named him "Shalashaska."

Sometime during Ocelot's career in the Soviet military, he met Colonel Sergei Gurlukovich, member of the Spetsnaz GRU unit as well. After the fall of the Soviet Union, Ocelot left Spetsnaz.

Ocelot's official file mentioned that after the fall of the Soviet Union, he joined the OMON (Special Purpose Police Squad) and the Russian Tax Police's elite SWAT team. Afterward he joined the SVR (a successor agency of the KGB). Ocelot eventually became dissatisfied with the agency's rigid system and left Russia. However, this account is considered to be false.

During the 1990s, he pursued mercenary work, cutting a swath through the world's hot spots as a spy and mercenary up until the early 2000s.

After Solid Snake foiled Big Boss's attempted coups d'état in Outer Heaven and Zanzibar Land, Zero put Big Boss in a nanomachine-induced coma to preserve the Patriots's messiah. This infuriated Ocelot and EVA, and as a result they both left the Patriots, though Ocelot did so in secret, in order to still operate as a spy and maintain their trust. EVA and Ocelot formed a plan to recover Big Boss's body from the clutches of Zero (a plan which wouldn't be fully realized until 2014).

In the early 2000s, Ocelot discovered that FOXHOUND was being commanded by Liquid Snake (one of Big Boss's sons) and joined the unit, becoming the unit's interrogation expert. Having held Big Boss in such high regard in his earlier years, he was more than willing to fight under one of his sons. Sometime in 2003, EVA and Ocelot became allies of Naomi Hunter, who had her adoptive brother, cybenetic test subject Gray Fox, kill FOXHOUND's medical chief, Dr. Clark (Para-Medic).

In 2005, Revolver Ocelot (while secretly working as an agent for U.S. President George Sears) incited Liquid Snake into bringing about an insurrection on Shadow Moses, along with the other serving members of FOXHOUND and the Next-Generation Special Forces. In addition, Ocelot used his influence to gain the support of his old comrade, Sergei Gurlukovich, who provided military hardware to the group, now calling themselves the Sons of Big Boss. During this time, Ocelot secretly provided Sears with information regarding the revolt.

Early in the insurrection, he tortured ArmsTech President Kenneth Baker then killed DARPA Chief Donald Anderson (a.k.a. Sigint) during a supposedly botched torture session. By doing so, he intentionally deprived Liquid of the necessary launch codes for Metal Gear REX, though the real reason was that Anderson recognized Ocelot as not truly working for the terrorists. Fearing this could have blown his cover, Ocelot killed Anderson. Furthermore, Ocelot's true reason was because Anderson was still in league with the Patriots and, by extension, Zero.

Revolver Ocelot challenged Solid Snake, who had been sent to Shadow Moses to eliminate the terrorist threat, to a gunfight. But midway through the duel, his right hand was cut off by the Cyborg Ninja and he was forced to flee, taking the amputated hand with him. Later, Ocelot interrogated a now-captured Snake, electrocuting him via his torture device. During the interrogation, he revealed his experience as a soldier as well as his allegiance to Sergei Gurlukovich and the "true motive" behind his actions.

Ocelot's true goal was realized when he retrieved REX's test data from Snake, as per the President's orders, without handing it over to Liquid. Towards the end of the Shadow Moses Incident, Ocelot discussed plans with Liquid concerning an alliance with Gurlukovich's mercenary forces, though this never came to be due to REX’s destruction at the hands of Solid Snake, Gray Fox, and Hal Emmerich. While Solid Snake defeated Metal Gear REX and Liquid, Ocelot took the REX data with him and escaped Shadow Moses, and later delivered it to President George Sears along with reporting the events that transpired.

After the incident, Revolver Ocelot (under Sears' orders) placed "the woman" under surveillance, sold REX's test data to many nations via the black market, and broke Naomi Hunter out of prison. At some point, he had his right arm replaced with Liquid Snake's arm.

In 2007, the Patriots ordered Revolver Ocelot to steal the U.S. Marines' Metal Gear RAY, which was seen as a threat to the development of the Navy's Arsenal Gear, and planned to mass-produce a redesigned model in order to protect it instead. On August 8th 2007, with the help of Sergei Gurlukovich and the Gurlukovich Mercenaries, Ocelot infiltrated the tanker in which RAY was being transported and stole it, sinking the tanker in the process. He also betrayed Gurlukovich, and left both him and Marine Commandant Scott Dolph for dead. The Patriots then continued with their plan (unaware that Ocelot still intended on betraying them), sinking a real oil tanker at the same spot, and constructing the Big Shell. All that was left to do was to manipulate Solidus Snake into the Patriots' trap.

On April 2009, Revolver Ocelot then met up with Solidus and the two formed the Sons of Liberty comprised of the remaining members of Dead Cell and the Gurlukovich Mercenaries, plotting to take over the Big Shell, which secretly housed Arsenal Gear. Solidus planned to eliminate the Patriots, completely unaware that his partner in the plan was one of them. He also attempted to eavesdrop on Ames and a disguised Raiden, but his attempt was thwarted when they went into Codec nanocommunication mode, to his annoyance. After Fatman was killed after attempting to blow up the Big Shell, Revolver Ocelot reported to Solidus Snake the possibility that Fatman was actually planted by the Patriots, gave the damage report for Shell 2, had planted the Semtex around the Shell connecting bridge, and got Emma to explain things relating to Arsenal Gear via truth serum. He also began feeling that his transplanted arm was beginning to try to take control again, and resorted to hypodermic injections to keep it at bay. He also had sore relations with Olga Gurlukovich, the new leader of the Gurlukovich Mercenaries, due to her belief that Ocelot abandoned her father when he was killed. Revolver Ocelot also encountered Raiden (an unknowing agent of the Patriots) prior to the death of Secret Service agent Richard Ames, and again, when he later assassinated U.S. President James Johnson. At the end of Raiden's mission, Ocelot revealed that all the events that had unfolded were scripted by the Patriots and that Solidus Snake and Raiden were merely pawns and had been part of a huge test scenario for one of the Patriots's new AIs; the only part that was unscripted was the appearance of Solid Snake.

Solid Snake's appearance was actually engineered by Liquid Snake. Through the transplanted arm, Liquid's "spirit" periodically possessed Ocelot's body with the goal of disrupting Ocelot's plan. At the climax of the Big Shell Incident, Liquid once again took control of Ocelot, crashing Arsenal Gear into Manhattan and escaping with Metal Gear RAY. Afterwards he headed off to take down the Patriots, although Snake theorized that the Patriots may have given Ocelot a bogus location to begin with. After the Big Shell Incident, Ocelot replaced Liquid's arm with a cybernetic one, namely with the intention of restoring balance to his mind.

By 2014, Revolver Ocelot's personality had merged with Liquid Snake's "spirit," thus creating the new entity of Liquid Ocelot. However, the truth was that Ocelot used a combination of nanomachines and hypnotherapy to become "Liquid's doppelgänger" in order to trick the Patriots.

In 2014, Liquid Ocelot was the CEO of the ultimate mercenary company and the benefactor of an all female mercenary unit (Laughing Octopus, Raging Raven, Crying Wolf, and Screaming Mantis) whose sole intent was to kill Old Snake.

Using Solidus Snake's DNA to enter the Patriots's AI network, Liquid Ocelot succeeded in taking over the system and used it to disable every gun and weapon in the world. After recovering the rail gun from the remains of Metal Gear REX on Shadow Moses Island, Liquid Ocelot used Metal Gear RAY against Metal Gear REX, being piloted by Old Snake. After REX and RAY were disabled, Liquid Ocelot retreated to an Arsenal Gear-class battleship stolen from the Patriots that he turned into his main base and outfitted with REX's railgun. He then planned to use the rail gun's nuclear warhead to destroy the Patriots's core AI that was orbiting around in space so he could allegedly replace it with GW and control the Patriots, even though he didn't take into account that his battleship would be chased by a worthless fossil.

After Snake and Otacon uploaded a computer virus created by Naomi Hunter (completed, unknowingly, with the help of Sunny Gurlukovich), Liquid Ocelot met Old Snake atop Haven, and also admitted when questioned by Snake about why he didn't stop him from stopping his plan that its because Snake completed the plan for him. After explaining the history of the Patriots conflict with Snake, he admits that while he is glad it succeeded, he still has a score to settle with Snake. There, Liquid Ocelot and Old Snake fought one last time. Revolver Ocelot's personality slowly began to resurface as the fight progressed, using his signature hand gestures and moves that he remembered from his fight with Big Boss back in 1964. After his defeat, believing that he has succeeded in his plans, Liquid Ocelot predicted that, with the Patriots gone, the world would descend into chaos, thus his goal (fulfilling Big Boss "Outer Heaven") is complete. His last words to Snake, now with the Liquid persona fully gone, were: "I am Liquid's doppelganger and you are his..." and "You're pretty good," the same phrase Revolver Ocelot said to Solid Snake in 2005 and the same phrase Big Boss said to Ocelot in 1964. Immediately afterwards, Ocelot's life was subsequently claimed by the new FOXDIE virus, designed by the Patriots to kill EVA, Liquid Ocelot, and Big Boss.

Little did he realize, however, that Sunny modified FOXALIVE to prevent the total collapse of civilization he had predicted, as Otacon explained soon after the fight it over. However, despite this, his plan did nonetheless leave many countries bankrupt from their use of PMCs and in a huge debt over their use of them, to which not even passing laws for regulating the use of PMCs would be enough in regards to paying it off.

Trivia

 * During Naked Snake's missions in 1964, there were a few allusions to Ocelot's American origins: his namesake, as Para-Medic pointed out, is a species of wildcat that lives on the American continent; and Ocelot's real name (Adamska) is the Russian form of "Adam," the agent whom Naked Snake was originally supposed to contact at Rassvet.
 * EVA, when explaining what she heard about Ocelot's backstory from Colonel Volgin, also mentioned that Volgin apparently raised Ocelot within GRU shortly after he was abducted by the Philosophers, despite it being in odds with Ocelot also working for the NSA and subsequently defecting from them.
 * Also, Ocelot was present in the West Wing of the Weapons Lab of Groznyj Grad when Volgin was beating up Naked Snake, despite the fact that Ocelot was not of Colonel-class.
 * During his torture of Solid Snake in 2005, Ocelot mentioned that, along with Afghanistan, he had participated in wars in Eritrea, Mozambique, and Chad.
 * In the aftermath of the 2007 Tanker Incident, he referred to his contact as "Mr. President." It is unclear whether he was referring to James Johnson (the president at the time) or the Patriots.
 * In 2009, Ocelot took a hypodermic injection to supposedly prevent Liquid Snake's arm from exerting control over him. During this occasion, his heart seemingly gave two heartbeats, as heard by Raiden, using a directional microphone.
 * While discussing his transplanted arm with Solidus, the surgery of which was performed in Lyon, Ocelot mentioned that he "never trust[s] a Frenchman." Ironically, Ocelot was born in Normandy, France, and his preferred method of torture (electrocution) was developed by the French military during the Indochina War, and then used during the Algerian War. It was nicknamed "La Gégène," an abbreviation of Génératrice, which means "Generator."
 * Ocelot was born on D-Day.

Unconfirmed history
During his time in the Soviet Invasion of Afghanistan, Ocelot was caught in a helicopter crash when his helicopter was shot down by Afghan guerrillas, and he still carries the wound that was inflicted in that skirmish. He also worked alongside Big Boss, while the latter was running his mercenary business in Africa. He may have received the FOXDIE Vaccination.

Metal Gear Solid
The original appearance of Revolver Ocelot (リボルバー・オセロット) in Metal Gear Solid was inspired by Western film actor Lee Van Cleef. Ocelot's nickname of Shalashaska (シャラシャーシカ) is a mistransliteration of Sharashka.

The Nintendo GameCube remake, Metal Gear Solid: The Twin Snakes, portrayed Ocelot as being right-handed, as he was able to show off with his gun with his right hand, but after it was cut off by Gray Fox, he attempted to do the same with his left in one scene and subsequently dropped his gun. However, he later managed to shoot the PAL Key right out of Snake's hand without harming Snake or damaging the key. Metal Gear Solid 3: Snake Eater later shows that Ocelot was equally proficient with both hands and he also used his left hand throughout Metal Gear Solid 2: Sons of Liberty.

Metal Gear Solid 2: Sons of Liberty
According to an interview with Yoji Shinkawa, Ocelot's arm was originally going to be mechanical as a result of Gray Fox amputating it. However, Liquid Snake was well received by fans, so they decided to change it to Ocelot receiving an arm transplant with Liquid Snake in Metal Gear Solid 2 as the donor instead.

Metal Gear Solid 3: Snake Eater
The defection of NSA codebreakers ADAM and EVA is based on a real life incident in September 1960.

Though, in Metal Gear Solid 3, both have the rank of Major, Ocelot and Raikov wear different insignia. Raikov's (two line along the shoulder strap with a single middle size star) is correct. Ocelot's (one line along the shoulder strap with three small size stars in a triangle and a fourth past the top point of the triangle) is the insignia of a Soviet Captain.

Ocelot's trademark gesture, where he points two fingers as if a gun, was ad-libbed by Kanazawa Tarou, Ocelot's motion capture actor.

The scene where EVA escapes from Ocelot's grip was originally intended to be much longer: EVA jumps down from the platform after kicking Ocelot, and Ocelot jumps down after her. Ocelot grabs her just as she boards her motorcycle, causing Snake to hesitate in pulling the trigger, as he'd risk hitting EVA if he attempted to shoot Ocelot. EVA then hits the accelerator hard and raises it in a similar fashion to a horse and attempts to hit Ocelot with the raised front wheel. Ocelot is hit, but won't let go, with EVA attempting to stand on the raised tire with the struggle continuing. This ultimately was cut from the final version, and was instead replaced with Ocelot falling off the platform after being kicked by EVA.

Metal Gear Solid: Portable Ops
Some fans had previously speculated that Ocelot was the "deviously cunning strategist" that Gene mentions to Big Boss in Metal Gear Solid: Portable Ops. This was contributed, in part, by the game's reuse of artwork, which originally depicted Ocelot, though it was obscured by shadow to make it virtually unrecognizable. However, Metal Gear Solid: Peace Walker later revealed that Hot Coldman was the man in question.

Metal Gear Solid 4: Guns of the Patriots
In the English release of Metal Gear Solid 4, Patric Zimmerman (Ocelot's English voice actor in Metal Gear Solid and Metal Gear Solid 2) voiced Liquid Ocelot. However, the casting for the Japanese release occurred differently due to the death of Kōji Totani (Ocelot's Japanese voice actor in Metal Gear Solid and Metal Gear Solid 2) in 2006. Banjo Ginga (Liquid Snake's Japanese voice actor in Metal Gear Solid and Metal Gear Solid 2) was therefore cast to voice Liquid Ocelot. Banjo Ginga also voiced Zero in Metal Gear Solid 3 and Portable Ops, the man who Ocelot (along with EVA and Big Boss) rebelled against.

The Metal Gear Solid 4 Database states that Ocelot never worked for OMON, the SVR, or the Russian Tax Police. The official file on Ocelot was falsified to cover up his membership of the Patriots.

Metal Gear Solid: Peace Walker
Metal Gear Solid: Peace Walker is the first Metal Gear Solid title not to feature Ocelot, though he was indirectly mentioned in one of EVA's tapes to Big Boss, regarding the assassination of The Sorrow (his father) by The Boss (his mother) in 1962.

Super Smash Bros. Brawl
In Super Smash Bros. Brawl, during Solid Snake's in-game Codec conversation with Mei Ling regarding Pikachu, Ocelot is briefly mentioned as Snake recounts the famous torture sequence in Metal Gear Solid, implying that the lethality of Pikachu's electric-based attacks falls in comparison to the interrogation he endured at the hands of Ocelot.

Metal Gear Solid/The Twin Snakes
Depending on the player's actions during the game, Ocelot will have different dialogue in certain scenes:


 * During the fight against Ocelot, should Snake accidentally kill Kenneth Baker, Ocelot will call Snake an "idiot" during the Game Over sequence.


 * If the player fights Ocelot too many times and manages to defeat Snake, Ocelot will remark that Snake will never live up to the Boss's name (referring to Liquid Snake) post-battle. Likewise, Ocelot will also give a different response when his hand is cut off by Gray Fox.


 * Prior to the torture sequence, if the player hasn't saved since starting the game, Ocelot will remark to Snake, "You don't want to go down that long road again, do you?"


 * If Snake is killed during the torture session, Liquid Snake will berate Ocelot for "doing it again" during the Game Over sequence, with Ocelot apologizing. This is in reference to the supposedly botched torture session with the DARPA Chief.


 * If the player survives the torture session, Ocelot reveals that Solid Snake is actually the inferior clone, and that the U.S. President is the third clone known as Solidus, during the post-credits telephone conversation. He also refers to keeping "the woman" under surveillance.

Metal Gear Solid 3: Snake Eater

 * Shooting the markhor during Naked Snake's battle with Ocelot, at the Bolshaya Past Crevice, will cause Ocelot to yell, "Son of a bitch!"


 * If Snake had any food in his backpack when he was captured by Volgin, EVA will reveal to him that Ocelot stole all of the food and ate it, during an optional radio conversation, after retrieving his gear.


 * A hidden R1 moment in Metal Gear Solid 3 shows Ocelot secretly in attendance during the ceremony where President Johnson awarded Naked Snake with the title of "Big Boss," along with the Distinguished Service Cross.


 * If Snake kills Ocelot after the latter passes out in the Virtuous Mission, or during the first fight with Colonel Volgin in the Shagohod hangar, the result will be a Time Paradox/Game Over.

Metal Gear Solid: Portable Ops recruitment
In Metal Gear Solid: Portable Ops, the player is given the option to recruit Ocelot. Ocelot is not recruited in the normal manner, but will be unlocked after completing the game, in the next playthrough. This section details how the recruitment takes place.


 * After recruiting Sokolov, the player will be informed of a Spy Report from the Silo Entrance that was never actually received. Head to the Silo Entrance and interrogate the Soviet Officer located on top of the bridge area. The Officer will mention "a man with twirling revolvers" who was seen in the Town.


 * A Spy Report from the Town will then be received, regarding a Government Official who prowls around at night time. Head to the Town at nightfall and locate the Government Official in one of the upper buildings. Interrogate him about the "revolver-twirling man," and he will mention that he went to the Airport to visit a friend.


 * Travel to the Airport and interrogate the FOX soldier at the control deck in order to learn the man's radio frequency: 141.23.
 * Recruit EVA (for more information on how to do so, see here).

His careers are Spy, Arms Dealer, and Gambler. He comes with the Single Action Army. The North American password for an alternate means of unlocking him are R.R.R. The EU password is THE-SON.
 * Next, travel to the Ravine and infiltrate its communication building. To do so, find the Key located on the second level of a nearby cave. Enter the building and contact the man's frequency (141.23), who is then revealed to be Ocelot. After the following conversation, proceed to complete the game and Ocelot will be automatically be recruited in the next playthrough.
