Big Boss

Big Boss (ビッグ・ボス) was the codename of the legendary soldier who founded the US Army Special Forces Unit FOXHOUND. He was also the founder and commander of Militaires Sans Frontieres, the "military without a government", which led to the creation of the mercenary nation, Outer Heaven. Big Boss later helped the small nation of Zanzibar Land achieve independence in Central Asia, becoming its head of state. Big Boss was considered by many to be "The Greatest Warrior of the 20th Century" and a brilliant military leader. He was hailed as a war hero by admirers and feared as a tyrant by his enemies. As a result of the Les Enfants Terribles project, he was the genetic father of Solid Snake (his subordinate and later nemesis), Liquid Snake and Solidus Snake.

Prior to earning the codename of Big Boss, he served as a field operative for the CIA black ops unit FOX and the apprentice of The Boss under the codename of Naked Snake (ネイキッド・スネーク Neikiddo Sunēku) during the Cold War.

Early Years
Big Boss's military career dates back to the 1950s, when he participated in the Korean War and joined the Green Berets. During John's tenure, he became The Boss's apprentice. In 1954, John was involved in the Bikini Atoll testing of the first airborne detonation of a hydrogen bomb. However, unlike most of his friends who were present during the testing who had gotten at least lukemia or thyroid cancer, or worse died from the radiation, he had not developed any symptoms at all. However, he did admit that he would eventually start showing symptoms sooner or later. This was later confirmed when it is revealed that his exposure to radiation resulted in him becoming sterile and unable to reproduce naturally. During John's time under the tutelage of The Boss, she taught him everything about combat, weaponry, survival, espionage, destruction, psychology and foreign languages like Russian. They also developed CQC together. The Boss and John went their separate ways on June 12, 1959.

In 1961, John carried out covert operations alongside Python during the early stages of Vietnam War, before America officially participated. He later stated that Python was one of the few soldiers he could completely rely on in battle. The two were involved in a mission together, where Python was shot and presumed to have been killed.

In 1964, John took part in the Virtuous Mission as a member of the CIA's FOX unit, in which he was to rescue a defecting Soviet scientist named Sokolov. It was during this mission that he was given the codename "Naked Snake" in honor of The Boss's former unit, the Cobra Unit. It was also during this mission that he participated in the world's first High Altitude-Low Opening (HALO) jump. However, this mission failed, due to the defection of The Boss. As a result of the events that followed the failure, he was also imprisoned by the US Government while in intensive care, with the government considering executing Snake because they thought he might have had involvement in The Boss's defection.

A week later, the government decided to pardon Snake of any involvement in The Boss's defection, under one condition: The FOX unit and Snake were to participate in Operation Snake Eater, in which the objective was to eliminate The Boss and her new Soviet ally, Colonel Volgin, rescue Sokolov and destroy the Shagohod. It was during this mission that Snake came across the prototype designs for the TX-55 Metal Gear and Metal Gear REX from Granin, who was sending them to a colleague in America.

During this mission, Snake had to fight off members of The Boss's former unit, the Cobra Unit. He also attempted to disguise himself as Major Raikov and knock out the real Raikov to infiltrate the production facility of Groznyj Grad, rescue Sokolov and find out how to destroy the Shagohod. However, the rescue attempt backfired when Volgin, being Raikov's lover, saw through his disguise easily and resulted in his capture. Snake had his right eye accidentally damaged by Ocelot's Colt Single Action Army, while in captivity for torture, in order to save EVA's life. However, he succeeded in completing the mission, and killed The Boss. For this, he was awarded the code name "Big Boss" and the Distinguished Service Cross by President Lyndon B. Johnson.

Big Boss, however, was heavily affected by the events of Operation Snake Eater. He had been forced to kill his old mentor, The Boss, and discovered that the whole operation (including The Boss's supposed defection) was a ruse set up by his government, to avoid taking the blame for a nuclear attack, while secretly getting their hands on the Philosophers' Legacy. Big Boss lost sight of what he was fighting for, and with it, his patriotism for his country. Because of this, he decided to retire from FOX. He was mentally discouraged and alone. Unbeknownst to him, his disposing of Colonel Volgin had also made him a hero to the people of the Soviet Union.

Post-Snake Eater
In 1966, Big Boss encountered a war orphan named Frank Jaeger during his time as a mercenary in the Mozambican War of Independence. After defeating him in battle and nursing him back to health, he rescued the child and escorted him to a rehab facility where he could be taken care of.



Although he had been labeled Big Boss and became a legend in the Black ops world due to his exploits, he continued to refer to himself as Naked Snake, as he did not yet feel that he had surpassed The Boss's skill. On November 1970, the FOX unit was considered rogue after its members organized a revolt and took over a Soviet base in South America, on the San Hieronymo Peninsula. Big Boss was captured by FOX and taken to the peninsula, where he was imprisoned and interrogated.

He met fellow prisoner Roy Campbell, a member of the Green Berets who had originally been sent to take care of FOX. The two managed to escape and went on to persuade former Red Army soldiers, along with disillusioned FOX operatives, to join forces with them and rise up against the renegade members (forming the early beginnings of what would become FOXHOUND). Para-Medic and Sigint also helped in defeating FOX and clearing their names, as well as Major Zero's (they were all partially blamed for the uprising).

During this time, Big Boss met Null (Frank Jaeger) and the two fought on a number of separate occasions. He also met Python once again, who had not died during the Vietnam War, but was kept alive by the CIA and trained as an "anti-Snake" because of his knowledge of Big Boss's fighting style. Despite Python knowing this information, he was defeated. He also learned near the end of the mission from Cunningham, who initially seemed like he was trying to get the other half of the Legacy from Snake, that his actual mission from the United States Department of Defense was to force Gene to launch Metal Gear to tarnish the CIA's reputation, and to do that, they had Snake recruit many people in Gene's army into resisting Gene. However, Snake fought and killed Cunningham so he can destroy Metal Gear. Big Boss then went on to kill the renegade FOX unit's leader, Gene, although not before learning that, contrary to what was told to him, The Boss's death was actually planned from the very beginning by "a single deviously-cunning strategist". Afterwards, with the help of the Red Army soldiers he had recruited, destroyed Metal Gear that FOX was threatening to launch into the United States. Gene left Big Boss with a large cache of funds and supplies that he intended to use in the creation of Army's Heaven. The official press, however, had changed it to his going to San Hieronymo to take down the base. After the incident, Big Boss officially formed FOXHOUND, to carry on the tradition of the FOX unit and to give a home to the soldiers he had recruited during the San Hieronymo Incident. Also, he had received another medal for his service.

The Patriots and Les Enfants Terribles
Ocelot and Zero later extended an invitation to Big Boss to join them in the formation of a new organization known as "The Patriots". This organization was to be set up in honor of The Boss's last wish. Big Boss, who knew her better than anyone else, was chosen by Zero to be an icon and hero to the world (although he was also chosen in part to get Ocelot to help him with his project). Some time after Big Boss joined the Patriots, he participated in a rescue mission in Hanoi to rescue EVA and recruit her into The Patriots. Zero started spreading stories about him. Some of these tales were true, some exaggerated, and others were false. Big Boss later became infuriated with Zero's lust for power, and was sick of playing the role of a puppet.

Afraid of losing Big Boss, Zero planned to finish up a secret project started in the late 1960s, initiated by Then-president Lyndon B. Johnson. In 1972, Big Boss was gravely wounded from a battle and shortly thereafter fell into a coma. Zero brought his unconscious body to a lab, where his genes were extracted to make genetically enhanced soldiers. This project would be known as "Les Enfants Terribles". Solid Snake, Liquid Snake, and Solidus Snake were produced in this program, and were known as the "Sons of Big Boss". However, this was the final straw between the two, and Big Boss left The Patriots with a determination to oppose them. He left the United States and FOXHOUND, drifting from country to county as a lone soldier.

Big Boss returned to Vietnam as a mercenary to participate in Long Range Reconnaissance Patrols (LRRP), and later served alongside SOG (Studies and Observation Group), Green Berets, US Army Rangers and the Wild Geese. Afterwards, he established his own guerilla group known as Militaires Sans Frontieres.

Peace Walker
On November 4, 1974, Big Boss stationed the Militaires Sans Frontieres in the Barranquilla Coast of Colombia, where he was approached by Gálvez and Paz from Costa Rica, a "Nation without a Military". Since the Cuban Missile Crisis, Latin America had become a key to maintaining the power balance between East and West, though Costa Rica had miraculously managed to maintain its peace and neutrality. However, in various regions of the country, a mysterious armed force seemed to be engaged in specific activities, claiming to be an "international police force" hired by the Costa Rican Development Agency (known as CODESA). However, Galvez doubted this was the case as they were shipping in a lot of advanced equipment. He also told Snake that he believed that the armed force was actually employed by "la cia". When Galvez attempted to hire Big Boss and the Militaires Sans Frontieres to hold back the invasion, Big Boss was reluctant to get involved, as he did not want his unit to become a "dogs of war" group, and suggested that Galvez try and get a negotiator that he knew to the Costa Rican national government to settle the dispute. Big Boss eventually agreed when Galvez revealed that he knew who Big Boss really was, as well as learning from a Sony Walkman bird recording from Paz's late friend that The Boss had apparently survived their fight at Rokovo Berej. Six days later, to preserve peace in the region, the Militaires Sans Frontieres moved into action. In time, they would come to be known as the founders of "Outer Heaven".

Later Career
By the early 1980s, Big Boss had completed more than 70 missions, and went on to participate in several regional conflicts and ethnic liberation wars. He fought in the Mozambican Civil War, during which point he rescued Gray Fox (Frank Jaegar) for the third time, this time from a FRELIMO Prisoner of War camp (as Gray Fox was a RENAMO operative during that point).

After taking part in the Rhodesian Civil War, Big Boss took Frank Jaegar and Naomi Hunter to the United States after the end of that war in 1980. Afterwards, Frank and Big Boss returned to Africa to continue fighting, leaving Naomi behind in America.

Big Boss achieved near-mythical status due to his extraordinary military career, earning him the "Legendary Soldier" moniker. He was heralded as a true hero and made the front covers of popular magazines in many countries.

Afterwards, he served as a combat instructor and worked to reintegrate former child soldiers into society, including a young girl.

Creating Outer Heaven
Using Gene's large cache of funds and resources, along with the funds he amassed as a mercenary, Big Boss began to bring about his vision of Outer Heaven. He created a military fortress to use as the main base of his personal mercenary dispatch company, deep in South Africa. In the early 1990s, he returned to the US to once again take command of FOXHOUND, the special forces unit he had founded almost two decades earlier. While serving as FOXHOUND commander, he planned on secretly building up his mercenary company into a larger military establishment.

Big Boss then kidnapped Russian scientist Dr. Drago Pettrovich Madnar and his daughter, forcing him to develop a new Metal Gear prototype, codenamed TX-55. It was a weapon system designed to give Outer Heaven military supremacy over the West, and thus giving Big Boss the power he needed to confront The Patriots.

At some point before the Outer Heaven Uprising, he taught Solid Snake the techniques of CQC as well as the importance of having the will to survive on the battlefield.

In 1995, when FOXHOUND was commissioned by the US to infiltrate Outer Heaven and destroy Metal Gear, Big Boss first sent in his most trusted soldier, Gray Fox, in a mission codenamed Operation Intrude N312; once Gray Fox was captured, Big Boss had briefed Solid Snake, at that time FOXHOUND's least experienced member, on the events of N312, and supplied him with a classified chart detailing how Gray Fox infiltrated Outer Heaven before FOXHOUND lost contact with him. He then sent in Solid Snake in the follow-up mission codenamed Operation Intrude N313. Upon Snake's arrival in the general vicinity, Big Boss, through Solid Snake's wireless radio, wished him luck and warned him that what Solid Snake will experience is nothing like he had ever experienced before in his service in the Gulf War. Secretly, however, Big Boss figured that there was no way that a rookie like Solid Snake could fulfill such a mission, that his efforts would delay further action by the West and buy Big Boss enough time to complete Metal Gear's development.

However, much to Big Boss's surprise, Solid Snake succeeded in infiltrating Outer Heaven, recovering the Metal Gear research data, and was planning to destroy Metal Gear itself. Faced with the failure of his plans, Big Boss attempted to get Solid Snake to delay the mission, including trying to trick him into boarding a military truck heading back to Building 1, luring him into a room in Building 3's ground floor that had a pit-trap, and even telling Solid Snake to abort the mission. When Metal Gear TX-55 ended up being destroyed, Big Boss confronted Solid Snake in the heart of Outer Heaven, and revealed his identity as Outer Heaven's mastermind. He then told him the truth behind his mission. After Big Boss activated the base's self-destruct countdown, the two of them engaged in one-on-one combat, with Big Boss dodging between crates and firing at Snake with some kind of machine gun. Even in his advanced age, Big Boss proved fast and dangerous, but Solid Snake eventually managed to defeat him.

However, Big Boss managed to survive and escape Outer Heaven. After NATO had conducted an air raid to bomb all of the refugees and war orphans within the area (regardless of their ties to Outer Heaven or not), he managed to save many of the refugees, war orphans, Outer Heaven mercenaries and Resistance members (whom he forgave). He later fled with the survivors to the Middle East.

In 1997, Big Boss and his followers had participated in the Mercenary War and helped give a fledgling nation on the border of the former USSR, Pakistan, China, and Afghanistan, Zanzibar Land, formerly known as the Zanzibar Province of the Soviet Union, its independence. After Zanzibar Land's independence was granted, they elected him to be the President of the new country. Recruiting war orphans from across the Third World and raising them as soldiers, Big Boss hoped to create a nation by and for soldiers, where soldiers were honored and not treated as political tools. Big Boss also recruited Gray Fox to his cause, and to ensure Zanzibar Land's success, he once again commissioned the creation of a more advanced Metal Gear prototype, known as Metal Gear D. This time, Dr. Madnar developed the new model of his own free will, after being branded a madman in the US. It is rumored that Dr. Madnar also provided Big Boss with cybernetic body parts to compensate for the injuries he received in Outer Heaven.

In 1999, Solid Snake once again managed to infiltrate the enemy nation's stronghold and destroy Metal Gear. Snake eventually defeated Gray Fox, hand-to-hand, in the middle of a minefield. Injured and unarmed, Snake was once again confronted by a machinegun-wielding Big Boss. Having spent his entire life on the battlefield, Big Boss could not conceive of a world without war. Big Boss paraphrased his mentor's final words to Solid Snake before challenging his son to one final battle.



"Whoever wins, our battle does not end. The loser is free from the battlefield, but the winner must remain there and the survivor must live his life as a warrior until he dies."

- Big Boss to Solid Snake, Metal Gear 2: Solid Snake

Snake managed to cobble together a makeshift flamethrower, using a can of lacquer spray and a cigarette lighter, using it to incinerate Big Boss, although not before revealing to Snake that he was, in fact, his father.

After "Death"
Big Boss's body was recovered by the US government and they discovered that he was still alive, despite suffering major injuries. He was then injected with nanomachines in order to induce an artificially induced cryogenic coma. For Zero, Big Boss was an irreplaceable icon and, more importantly, an irreplaceable friend. Big Boss's genome was then used to identify the so-called "soldier genes", which the US government used to create the Next-Generation Special Forces via gene therapy.

Big Boss's body was said to be in cold storage to preserve his remains. A grave was laid next to The Boss's grave, which read: "A Hero Forever Loyal to the Flames of War, Rests in Outer Heaven. 193X - 1999". This was in order to reaffirm Zero's lore that Big Boss was indeed dead.

In 2005, his body was also subject to a terrorist threat. The Sons of Big Boss, led by Liquid Snake, demanded that the US Government hand over Big Boss's body, along with one billion dollars, or they would launch a nuclear warhead from Shadow Moses Island, courtesy of Metal Gear REX.

The Patriots used Big Boss's DNA and biometric data for the SOP ID recognition system, the use of which allows access to the Patriots' AIs.

Sometime prior to 2014, the Patriots, via the Pentagon, declassified documents relating to Big Boss's exploits during the 1960s, which evidentally contributed greatly to his legend to the populace, and his CQC was also being taught in the military (although not to the extent of how Big Boss used it).

Although badly burned, his body was later recovered by EVA, with the assistance of Raiden. EVA, along with her rebel group, was able to rebuild him using body parts of his sons, Liquid and Solidus. When they were finished, Big Boss was restored to his former appearance. In 2014, when GW was properly destroyed, it led the way open into JD, which, in turn, revealed the location of Zero. Big Boss, now fully revived, proceeded to find him.

After Solid Snake had attempted suicide in Arlington National Cemetary, Big Boss emerged from behind with Zero; telling his son that there was no hatred between them. Despite his age, Big Boss was still a formidable fighter and was able to disarm Snake with ease then embrace him in a fatherly hug.



Big Boss told Snake about the history of the Patriots and the struggle between Zero and himself. He also told Snake that Ocelot had used hypnotherapy and nanomachines as part of his plan to become Liquid Snake's doppelganger. Big Boss was informed of the switch from a video that Naomi had left him when he awoke. As Zero was sitting in his wheelchair in a vegetative state, Big Boss commented that, although there was bad blood between him and Zero, all he felt now was "a deep sense of longing, and pity". He pondered on whether Zero hated or feared him. Big Boss then switched off Zero's air supply machine, killing him and finally ending their conflict. Soon after that, Big Boss started to feel the effects of the new FOXDIE virus that was injected into Snake. While in pain, he requested Snake to take him over to The Boss's grave. He stood and saluted, echoing to his salute 50 years beforehand. He said that ever since he killed The Boss, he "was already dead". Sharing one final smoke, Big Boss finally made peace with his last-living son, and, as a last request, pleaded with Snake to spend his final days in peace and not waste them fighting, and both agreed. Moments later, Big Boss, the greatest soldier who ever lived, passed away at the grave of the woman whose life and death had made him into the person he was.

"This is good... Isn't it?"

- Big Boss's final words.

Legacy
Big Boss's influence on the world could be compared only to The Boss. He inherited her dream of a unified world free from the short-sighted ambitions of nations, soured by the senselessness he perceived in her death. Though he stated during the Virtuous Mission that he would die in the service of his country if that was necessary, the death of The Boss showed him there was no purpose in doing so. This realization led him to create Outer Heaven; a nation where, in his words, "every soldier will have his place, and where they will answer to no government." This ideal would persist decades into the twenty-first century.

He thus spent many of his later years in conflict with The Patriots, individuals who followed a different interpretation of The Boss's will - that of a world ruthlessly unified by the age-old methods of intrigue and espionage. Lacking their economic resources and popular support, Big Boss believed there was no way that he could change the world, even if he was the world's greatest soldier. However, he still chose to fight for what he believed in. This determination earned him many admirers and followers, even long after his "death". Over and over again the standard of "Outer Heaven" would be raised in defense of those who suffered due to the machinations of The Patriots.

Big Boss also saw Solid Snake as a soldier rather than a son, but he always knew his eldest son was loyal to the end, as The Boss was. As a last chance to prevent him from making any more terrible mistakes, Big Boss told his son to spend the rest of his life not as a soldier, but as a man. Spending his entire life fighting and experiencing sorrow, Big Boss made it clear that no one needs to die for another person's cause. People must believe in themselves and fight for what they feel is right, for in the end they alone can judge their own deeds.

Naming Controversy
Much controversy and debate surrounds Big Boss's real name. When Metal Gear Solid 3 was released players safely assumed his real name was Jack, as The Boss and Zero called him by this name on several occasions.

However, early on in the game Big Boss is asked by Para-Medic what his real name is, to which he responds "John Doe" with Para-Medic replying "and they call you Jack for short?" Due to slightly tongue-in-cheek nature of the conversation most initially thought it was nothing more than a joke. However, at the end of MGS3, Big Boss also tells Ocelot that his name is John, and in Japan, a Limited Edition release of MGS3 included a book called R which stated Big Boss's real name was John Doe. The master Patriot AI, which is accessed via Big Boss's biometric data, is also named John Doe (although it is to be noted that it is also possible that JD was named as such as a reference to the fact that the current leaders of The Patriots are "no one" (IE, AIs)).

To further add to the confusion, the Metal Gear Solid 4 Database listed Big Boss's name as simply "John". However, both names can be applicable as the name "Jack" in English is the diminutive form of the name "John".

Other Appearances
Big Boss appears in Super Smash Bros. Brawl as both a trophy (as Naked Snake) and sticker. His trophy description is as follows:



"As a member of the special-forces unit FOX, Naked Snake assassinated The Boss and ruined the Shagohod, a Soviet nuclear weapon. Years later, he was used to plant the seeds of Les Enfants Terribles, a project designed to create cloned super soldiers. The three Snakes - Liquid, Solid, and Solidus - were thus born. He would then embrace his name, Big Boss, and duel Solid Snake."

His appearance as a sticker grants the highest possible Flinch Resistance of +160 in the Subspace Emissary Adventure Mode.

During a codec conversation about Toon Link, Solid Snake mentions to Mei Ling that "there's been more than one Snake". He is referring to his father, Big Boss, his two brothers, Liquid Snake and Solidus Snake.

Also, several of Naked Snake's camouflage uniforms appear as alternate costume options for Solid Snake.

Big Boss also appears as the second-to-last boss in the NES sequel to the original Metal Gear, Snake's Revenge. He guards the final fortress where Metal Gear 2 is located. At first, he fights with a machine gun just as he did in the original Metal Gear. After being shot several times, Big Boss reveals that he survived his injuries from Outer Heaven through surgeries that turned him into a cyborg; he then transforms into a 12-foot tall RoboCop-like robot, and proceeds to chase Solid Snake around while firing napalm shells at him. However, Snake lures him out of the command room and places mines on his feet, which ultimately destroys him. Despite his defeat in this game, Metal Gear 2 was still activated.

While Snake's Revenge is non-canonical, it should be noted that the final battles against Big Boss in Snake's Revenge and Metal Gear 2 are quite similar. In both games, Big Boss can use doors to chase the player around from one screen to another. The only difference between the two games' sequences is that Big Boss doesn't transform into a cyborg in the canonical sequel, Metal Gear 2.

In Metal Gear 2, when the player calls George Kasler during the final battle, he mentions a rumor about Big Boss receiving cybernetic "snatcher" organs from Dr. Pettrovich after losing his limbs, right ear and right eye (which was already missing in the original game) in battle. While some fans interpret this as a jab directed at Snake's Revenge, it's actually a reference to Kojima's previous game, Snatcher. Dr. Petrovich appears in Snatcher as the founder of the Snatcher Project. Strangely, this reference was counted as canon by the Metal Gear Solid 4 Database.

While Big Boss never actually appeared in Metal Gear Solid, he did appear in the novelization by Raymond Benson as part of Psycho Mantis's forcing himself into Solid Snake's mind where he along with Meryl Silverburgh and Otacon were trapped in the funhouse mirrors. While he was ultimately resigned to his fate, he does beg Snake to input the detonation codes, as otherwise the Sons of Big Boss would kill him.

Trivia

 * Big Boss is, presumably, afraid of vampires. He states that thinking about them gives him nightmares, during a radio conversation with Para-Medic regarding vampire bats. For this reason, he'd rather she didn't utter the name "Dracula" when speaking to him (as she is quite a movie buff).
 * Prior to Operation Snake Eater, Big Boss had been awarded the Army Achievement Ribbon, the Good Conduct Ribbon, and the Distinguished Service Cross Ribbon, along with several others. He wore these during the award ceremony in which he was bestowed both the Distinguished Service Cross Medal and his title of Big Boss by President Lyndon B. Johnson.
 * During the San Hieronymo Takeover, if Naked Snake recruits Para-Medic, he tells her in an optional codec conversation that he wanted to be an instructor after the events of Operation Snake Eater. In his later years, Big Boss did eventually serve as a combat instructor and worked to reintegrate former child soldiers into society. Ironically, he ended up believing that soldiers on the battlefield could never be reintegrated into society.
 * In the early 1970s, sometime after joining the Patriots, he received a snake-shaped scar across his chest similar to that of his mentor, The Boss. How he had gotten the scar is currently unknown.
 * After reassuming command of FOXHOUND in the 1990s, Big Boss was responsible for the wild and instinctive strategies utilized by the unit during operations, which often appeared to be planned with little caution and detail. This somewhat alluded to his true motivations in preventing FOXHOUND from interfering with his plans for Outer Heaven.
 * According to some of the children in Zanzibar Land, Big Boss doesn't like adults, referring to his hate for the world's politicians and, by extension, the Patriots.
 * Interestingly, despite his dream of wanting to create a world in which soldiers were honored and not treated as political tools, Kyle Schneider implied that Big Boss seemed to want Snake to succeed in his mission to rescue Kio Marv from Zanzibar Land.


 * Liquid Snake claimed that Big Boss was in his late fifties when his DNA was extracted for Les Enfants Terribles. However, his gravestone implied that he was born sometime in the 1930s: with the twin Snakes born in 1972, this would have made him a maximum of 42 at the time. This is likely just a mistake on Liquid's part, as he has also been misinformed on other occasions.
 * In an optional codec conversation in Metal Gear Solid 3, Naked Snake tells Major Zero that he doesn't have any (biological) brothers. However, the rivalry between Naked Snake and Ocelot in Metal Gear Solid 3 is (in a way) like brothers with Snake as the big brother and Ocelot as the little brother. Also in Metal Gear Solid: Portable Ops, Gene considered himself and Naked Snake as being "like brothers".

Behind the Scenes

 * In the Metal Gear Solid Official Mission Handbook, Big Boss is described as having been born in Hawaii, and of Japanese-American descent. It was also stated that his entire American side of the family had perished from the Japanese attacks on Pearl Harbor, while his Japanese relatives were locked up in the internment camps. It is said in the guide that his first taste of battle was during World War II, where he served in his teens and was drafted into the 442nd Infantry Regiment and had participated in freeing French towns from Nazi control in 1944. It is also implied that he lost patriotism for America due to suffering from prejudice due to his being of Japanese descent, and had participated as a mercenary for France in the Congo Crisis in 1961 which he served until 1968, and then served in wars in Asia, Africa, and the Middle/Far East. However, the information was not included in any of the games or the Metal Gear Solid 4 Database, so its status as canon is questionable. However, when Big Boss questioned Elisa in regards to how someone as young as her was allowed to be on the battlefield, Elisa implies that Big Boss may have been around the same age when he got his first taste on the battlefield. On that note, the guide's claim that Big Boss had served in World War II as a teenager is also one of the first hints that Big Boss was born in the 1930s.
 * In the artwork for the Japanese MSX2 manual of Metal Gear, Big Boss's eyepatch is on the opposite eye, although his in-game character model displays it on his right eye.
 * The same manual also describes Big Boss as having been a previous member of SAS and GSG 9. However, this information was disregarded in the MSX2 manual for Metal Gear 2, and later the Metal Gear Solid 4 Database, so is assumed to no longer be canon.
 * In the instruction manuals for the NES version of Metal Gear and its sequel, Snake's Revenge, Big Boss was identified as Commander South, Colonel Vermon CaTaffy, and Higharolla Kockamamie for his roles as Solid Snake's Commanding Officer, the Commanding Officer of Outer Heaven, and his role as the enemy leader in Snake's Revenge, respectively. The names are a reference to Marine Lieutenant Colonel Oliver North, Libyan Dictator Muammar al-Gaddafi, and Ayatolla Khomeini, respectively.
 * Big Boss's look in the MSX2 version of Metal Gear 2 was modeled after actor Sean Connery. Like other characters, this image was updated during later releases of the game to reflect his look in official artwork of Metal Gear Solid, which was also carried over to his appearance in Metal Gear Solid 4.
 * In the original MSX2 manual for Metal Gear 2, Big Boss was stated to have lost his eye on the battlefield, during the late 1980s, which caused him to retire from active duty. During this time, he began to focus on military education and training. This information was later retconned in Metal Gear Solid 3. Also, in the same manual, it was stated that he had actually been nominated as the international planning commander of FOXHOUND in the early '90s, where he became transformed by greed and dreams of absolute power, resulting in his creation of Outer Heaven.
 * One of the mercenary units that he fought with, after serving in Vietnam, was the Wild Geese, a reference to the novel and 1978 war film of the same name, about a mercenary group participating in African conflicts. The novel itself was named after a 17th-century Irish mercenary army.
 * Prior to the release of Metal Gear Solid 3, Big Boss was originally to have learned the art of warfare from Dead Cell strategic master Old Boy, in the original story outline for Metal Gear Solid 2.
 * In Metal Gear Solid 2, Big Boss appears opposite both Solid Snake and Liquid Snake in a cutscene during Solidus Snake's explanation to Raiden of the similarities of their connection to the one shared by the Twin Snakes and Big Boss.
 * Naked Snake in the Olive Drab uniform is very similar looking to the appearance of Iroquois Pliskin. In early testing versions of Metal Gear Solid 3, Pliskin's model served as a placeholder for Naked Snake, as can be seen here.
 * During a conversation with The Boss, Snake mentions that he can't smell. Actually, it is the player that can not use their sense of smell to help play the game.
 * In the Japanese version of Metal Gear Solid 4, Big Boss is voiced by Chikao Ōtsuka, the real-life father of Akio Ōtsuka, who plays Solid Snake (and in the case of Metal Gear Solid 3, Metal Gear Solid: Portable Ops, and Metal Gear Solid: Peace Walker, Naked Snake/Big Boss himself).
 * Interestingly, the targets in Metal Gear Solid 4 's Virtual Range are named "John Doe".
 * In the non-canonical Metal Gear: Ghost Babel, it was stated that Big Boss was originally under orders by the US Government to form Outer Heaven as part of Project Babel, but he broke ties with the project, resulting in Operation Intrude N313.
