Characters of the Metal Gear series

The Metal Gear franchise, created by Hideo Kojima and with character and mecha designs by Yoji Shinkawa, features a large cast of characters, several of whom are several soldiers with supernatural powers provided by scientific advancements.

The series initially follows the mercenary Solid Snake. In the Metal Gear games, he goes on government missions to find the Metal Gears while encountering Gray Fox and Big Boss in Outer Heaven and Zanzibar Land. In the Metal Gear Solid games, he works with Otacon and Raiden while opposing Liquid Snake's FOXHOUND, Solidus Snake, the Patriots and Revolver Ocelot. Beginning with Metal Gear Solid 3: Snake Eater, several games have served as prequels, following Big Boss' past as Naked Snake and Venom Snake as well as the origins of the organizations.

While the characters of the Metal Gear games had designs modeled after Hollywood actors, the Metal Gear Solid games established consistent designs based on Shinkawa's idea of what would appeal to gamers, with several characters that he designed following ideas from Kojima and staff. Critical reception of the game's cast has been positive, with publications praising their personalities and roles within the series.

Creation and designs

Much as Metal Gear began as a pastiche of action movies of the time, characters were pastiches of contemporary action movie heroes. When Shinkawa began designing the characters in PlayStation's Metal Gear Solid, they were given their respective established visual appearances. Due to hardware limitations, Shinkawa designed them to appeal to gamers. Because of the time skip between titles, some characters were redesigned to fit in the game's setting. With the improved technology of consoles like the PlayStation and PlayStation 2, starting with Metal Gear Solid 2: Sons of Liberty the staff gave the characters a more realistic look, despite their initial doubts. This caused difficulties for the staff, as they had to make the faces more realistic. When illustrating characters, Shinkawa does not focus on minor details such as eyes, instead illustrating something more symbolic. While Solid Snake was easy to illustrate due to having a consistent design, with Big Boss's younger self, Naked Snake, being conceived via minor changes to his original version, other characters' designs were more time-consuming.

When they debuted, player characters Solid Snake and Raiden were meant to represent the player, but in subsequent games they gained more defined personalities. As Snake became more experienced in combat throughout the series, Kojima attempted to create more challenging antagonists for boss fights. This resulted in Big Boss's clones from Metal Gear Solid and Metal Gear Solid 2, who have the same abilities as Solid Snake, the Cobra Unit from Metal Gear Solid 3: Snake Eater, who participated in World War II, and the Beauty and the Beast Corps from Metal Gear Solid 4: Guns of the Patriots, who possessed few human traits. While villains in the first games had detailed backstories, the Cobra Unit members were intended to have little information known about them, resulting in a significant impact among players upon their deaths. This also made it difficult for Shinkawa to conceptualize their visual appearance, as he had little to no background information. By Metal Gear Solid 2, Kojima was inspired by the Sherlock Holmes novels to introduce a sidekick character in order to view Snake from a different perspective.

Metal Gear Solid also marked the first time that characters had voice actors, with Solid Snake and Naked Snake being voiced by Akio Ōtsuka. Ōtsuka remembers being surprised during his debut as a result of the large amount of dialogue Snake was given. In English, casting was directed by Kris Zimmerman and supervised by a member of Konami. Solid Snake's English voice actor was David Hayter, who, despite having issues with some of the dialogue in Metal Gear Solid, became attached to the series.

Various Metal Gear Solid games have been expanded upon in remakes and other media, such as Metal Gear Solid: The Twin Snakes, Metal Gear Solid: Digital Graphic Novel, Metal Gear Solid 2: Digital Graphic Novel, and Metal Gear Online.

Introduced in Metal Gear

Solid Snake is voiced by Akio Ōtsuka in Japanese and by David Hayter in English.

Gray Fox

Gray Fox (グレイ・フォックス, Gurei Fokkusu, spelled "Grey Fox" in the MSX2 versions) is a high-ranking agent of FOXHOUND, with the "Fox" codename being the highest distinction within the unit.

He first appears in the MSX2 games, where his face portrait was modeled after actor Tom Berenger. In Metal Gear, he goes missing during a mission to Outer Heaven, with his last transmission being a cryptic message that reads "Metal Gear". After Solid Snake rescues him, he reveals the TX-55 Metal Gear's true nature. In Metal Gear 2: Solid Snake, he pilots the advanced Metal Gear D and confronts Snake while secretly assisting him as an anonymous informant. The game reveals that he left FOXHOUND and defected to Zanzibar Land and expands on his past as Frank Jaeger (フランク・イェーガー, Furanku Yēgā, "Frank Yeager" in the MSX2 version), who fell in love with Czech figure skater Gustava Heffner while in Calgary. Gustava unsuccessfully attempted to seek asylum with him in the United States and was subsequently stripped of her competition rights. Afterwards, Jaeger came to resent his superiors, while being unaware that Gustava joined the StB and was working in Zanzibar as a bodyguard for Dr. Kio Marv. During his and Snake's first direct encounter as enemies, he accidentally kills Gustava while piloting the Metal Gear; after Snake destroys the Metal Gear, he challenges him to a fistfight in a minefield and is seemingly killed.

In Metal Gear Solid, Gray Fox returns as the original Cyborg Ninja (サイボーグ忍者, Saibōgu Ninja), having been grafted into a powered armor exoskeleton and armed with a high-frequency blade. According to Hideo Kojima, the Cyborg Ninja "was born from this Shin-chan's graffiti." During Liquid Snake's FOXHOUND revolt at Shadow Moses, Fox challenges Solid Snake to a fight, maiming Revolver Ocelot in the process, before disappearing in a violent rage. Throughout the game, he, as the faceless contact "Deepthroat", provides Snake cryptic advice through codec. Naomi Hunter eventually reveals to Snake that she is his foster sister and that he is the Cyborg Ninja. After revealing to Snake that he killed Naomi's parents and became her foster brother out of remorse for his actions, Fox fights Metal Gear REX and its pilot, Liquid, and destroys its radome with a prototype railgun. However, he is mortally wounded and is killed by REX after Snake refuses to kill him.

In Metal Gear Solid 2: Sons of Liberty, Raiden initially believes him to be alive during Solidus Snake's Manhattan incident before learning that the Cyborg Ninja is actually Olga Gurlukovich.

The non-canon prequel Metal Gear Solid: Portable Ops, set twenty-five years before Metal Gear, features a teenage version of Fox under the codename Null (ヌル, Nuru), a masked machete-wielding assassin. He is subjected to a secret CIA project to be the "Perfect Soldier" and recruited into Gene's corrupt FOX unit during the San Hieronymo takeover. Throughout the game, he fights Naked Snake before Snake realizes that Null was a boy in Mozambique who used his innocence as a cover to kill government soldiers with only a knife while speaking some German, leading to the name "Frank Jaeger", German for "Frank Hunter". Naked Snake then defeats Jaeger and sends him elsewhere for help.

Metal Gear Solid 4: Guns of the Patriots reveals that Frank Jaeger's murder of Para-Medic was part of a plan to free Big Boss from Zero's control.

There is a Cyborg Ninja unique character card in Metal Gear Acid. Outside of the Metal Gear games, the Cyborg Ninja appears as a driver in Konami Krazy Racers and an Assist Trophy in Super Smash Bros. Brawl and Super Smash Bros. Ultimate. The original Cyborg Ninja's exoskeleton appears as a downloadable content skin for Raiden in Metal Gear Rising: Revengeance, and Venom Snake in Metal Gear Solid V: The Phantom Pain.

Kojima was interested in developing a game with Gray Fox as the main playable character.

In Japanese, Gray Fox is voiced by Kaneto Shiozawa in Metal Gear Solid, Jun Fukuyama in Metal Gear Solid: Portable Ops, and Takumi Yamazaki in Metal Gear Solid: Digital Graphic Novel. In English, he is voiced by Greg Eagles in Metal Gear Solid, Rob Paulsen in Metal Gear Solid: The Twin Snakes, Super Smash Bros. Brawl and Super Smash Bros. Ultimate, and Larc Spies in Metal Gear Solid: Portable Ops and Metal Gear Solid: Digital Graphic Novel.

Following Cipher's destruction of MSF, Miller is embittered after seeing the concept of a nation for soldiers appropriated by other groups and reduced to being mercenary bands before Venom Snake rescues him from Soviet forces, enabling him to help with the Diamond Dogs mercenary group's expansion. Miller is distrusting of those affiliated with Cipher, accusing them of betrayal and calling for their deaths, and takes little satisfaction with vengeance on Skull Face, but believes in Diamond Dogs' cause.

Hal Emmerich was born in 1980 to scientists Dr. "Huey" Emmerich and Dr. Strangelove, who was born on the day of the Hiroshima bombing, with his grandfather having worked on the Manhattan Project. When he was a child, Huey attempted to use him as a test pilot for the Metal Gear ST-84, as it could only be piloted by a child. When Strangelove opposed this, Huey killed her during an argument. Years later, Huey married a British woman named Julie Danziger and they had a daughter, Emma. After Huey committed suicide by drowning himself in the family pool and attempted to drown Emma, she became estranged from Hal, blaming him for not trying to save her. Soon after, Hal ran away from home and dropped out of school, self-educating through the Internet and calling himself Otacon, short for "Otaku Convention", after becoming a fan of anime. After enrolling at MIT and earning a Ph.D. from Princeton University, while in college he was recruited by the FBI's Engineering Research Facility, but was fired after hacking into their database. He was later hired by Armstech, Inc. as lead engineer for the Metal Gear REX project. He was excited at the prospect of developing a mecha, like those in the anime he enjoys, and believed that it was a mobile defense system, when in reality it was a nuclear doomsday weapon.

In Metal Gear Solid, Otacon encounters Solid Snake and learns of Metal Gear REX's true nature. After falling in love with FOXHOUND member Sniper Wolf, he is distraught that Snake would have to kill her, but aids Snake in destroying REX and ending the terrorist uprising. According to the in-universe novel In the Darkness of Shadow Moses: The Unofficial Truth, Otacon allegedly left for Great Britain after the terrorist uprising to visit relatives. After the schematics for Metal Gear were placed on the black market by Revolver Ocelot, Snake and Otacon formed Philanthropy, an organization dedicated ending proliferation of Metal Gear-type weapons.

In Metal Gear Solid 2: Sons of Liberty, in 2007 Otacon receives an email from Emma, informing him of the new prototype Metal Gear RAY. However, the email is actually a trap for the Patriots to lure Solid Snake out of hiding and frame him for terrorism by having Ocelot hijack RAY and framing him with forged evidence. After faking Snake's death using Liquid Snake's corpse, he manages Philanthropy's activities while keeping Snake's survival secret from the public. In 2009, he receives an anonymous email from Liquid informing him of the development of Arsenal Gear in the Big Shell and Solidus Snake infiltrates it with SEAL Team 10 to rescue the hostages, including Emma. However, Emma dies due to stab wounds inflicted by Vamp and, before her death, admits that she always admired Hal and wanted to follow in his footsteps. Following her death, he falls into despair until Snake encourages him to move on and rescue the hostages. Afterwards, Snake meets with Otacon at their hideout and receives a disk containing info on the Wisemen's Committee.

In Metal Gear Solid 4: Guns of the Patriots, he and Sunny build a remote-control robotic companion to Snake, Metal Gear Mk. II, whose name was taken from a robotic character of the same name in Snatcher. He becomes romantically involved with Naomi Hunter until she commits suicide. In the finale, Otacon resolves to live with Snake and serve as a witness of his existence. By the time of Metal Gear Rising: Revengeance, Otacon is mentioned to have officially adopted Sunny.

Outside of the Metal Gear series, Otacon makes guest appearances in Super Smash Bros. Brawl and Super Smash Bros. Ultimate as one of Snake's support crew in codecs.

Otacon is voiced by Hideyuki Tanaka in Japanese and by Christopher Randolph in English.

Meryl Silverburgh

Meryl Silverburgh (メリル・シルバーバーグ, Meriru Shirubābāgu) is based on a supporting character of the same name in Hideo Kojima's earlier game Policenauts (1994), with Kojima adopting her name, likeness, voice actress (Kyoko Terase) and other characteristics due to his love for the character. Meryl's partner in Policenauts, Dave Forrest, shares Snake's given name. Dave (David), and, in the final scenes of Metal Gear Solid, Meryl wears an orange vest similar to the one Forrest wears in Policenauts. Character designer Yoji Shinkawa stated that the staff purposely avoided mentioning her directly in the first sequel to Metal Gear Solid so that it could follow either of the two endings from the first game.

The daughter of Roy Campbell's brother, Matt Campbell, who died during the Gulf War, she was born into a house of military traditions and trained herself in the 'arts' of soldiery. She admired FOXHOUND, viewing its heyday as when her uncle and Solid Snake were members, and joined the armed forces after graduating high school, undergoing psychotherapy to prevent attraction to the opposite sex. After being recruited by U.S. military unit Next-Generation Special Forces (Genome Soldiers), in 2005 she was assigned to Shadow Moses Island as an emergency replacement after several soldiers went missing. Upon arriving on the island, the unit involved with the exercise and members of FOXHOUND revolted and took over the island's nuclear disposal site, along with the Metal Gear REX being developed there. When she refused to join the mutiny, she was imprisoned along with ArmsTech President Kenneth Baker but escaped after stealing Johnny's uniform and disguising herself as a guard, during which she met Snake and began working with him. After FOXHOUND member Sniper Wolf captures her, Snake fights her in a sniping duel before being lured into an ambush and captured. He is then put through a series of torture trials by Revolver Ocelot, with the player's actions determining Meryl's fate. If the player successfully completes the section, Snake rescues a wounded Meryl and they escape, allowing Roy and Mei Ling to fake their deaths. However, if the player submits to the torture, Snake discovers that Meryl died during her imprisonment and leaves her body to be buried by the collapsing structure with REX's remains. When Snake informs Campbell of Meryl's death, Campbell reveals that she was his biological daughter, conceived from an affair between him and his sister-in-law, which was kept secret from her biological parents. The fictional publication In the Darkness of Shadow Moses by Nastasha Romanenko, included as a bonus feature with Metal Gear Solid 2: Sons of Liberty, states that Snake and Meryl escaped together.

In Metal Gear Solid 4: Guns of the Patriots, she is the commander of Rat Patrol Team One (RAT PT 01), a division of the United States Army Criminal Investigation Command sent to investigate Liquid Ocelot's private military company activities. She has learned that Roy Campbell is her true father, but resents him due to the circumstances of her conception and his marriage with Rosemary. However, she reconciles with him by the end of the game. She initially dislikes her subordinate Johnny due to his clumsiness and stomach problems, but forgives him after learning that he does not have nanomachines in his body, later falling in love with and marrying him. She also appears in Metal Gear Online as a playable character.

Meryl Silverburgh is voiced by Kyoko Terase in Japanese and by Debi Mae West in English.

Naomi Hunter

Naomi Hunter (ナオミ・ハンター, Naomi Hantā), called Dr. Naomi (ドクター・ナオミ, Dokutā Naomi) by her staff, is a geneticist by practice who specializes in nanotechnology-based gene therapy.

In Metal Gear Solid, she is the chief of FOXHOUND's medical staff and part of the support crew assembled to assist Solid Snake, providing him with information on the FOXHOUND members he faces. Being Gray Fox's adopted sister, she seeks revenge on Snake for nearly killing him during the original Metal Gear games. After being instructed to inject Snake with the FOXDIE virus, she secretly modifies it so that it will kill him at a random moment in addition to its original programming. Over the course of the game, Naomi realizes that some of her original perceptions of Snake were wrong and feels remorse for modifying the virus. Uncertain of when the FOXDIE would kill, Naomi tells Snake to live life to the fullest before he dies. Afterwards, Nastasha Romanenko's account reveals that Naomi was briefly arrested following the Shadow Moses incident until she escaped.

In Metal Gear Solid 4, Naomi works with Liquid Ocelot to hijack the Sons of the Patriots battlefield control system before allying with Snake. She becomes romantically involved with Otacon and forms a friendship with Sunny. Upon returning to Shadow Moses, Naomi reveals that she has been diagnosed with terminal cancer and, guilt-ridden over her past mistakes, commits suicide by disabling the nanomachines that were keeping it in check.

Naomi Hunter is voiced by Hiromi Tsuru in Japanese and by Jennifer Hale in English.

Mei Ling

Mei Ling (美玲（メイ・リン）, Mei Rin) is a Chinese-American data analyst.

In Metal Gear Solid, she is in charge of saving the player's progress. She invented Snake's wireless communication system, the codec radio, and the Soliton Radar, which detects the positions and field of vision of nearby enemy soldiers. Each time Snake saves his data, Mei Ling provides him with advice through Chinese proverbs, as well as quotations from Western authors. In the Japanese version, Mei Ling only quoted Chinese proverbs: she would cite the original proverb in Chinese and then explain its meaning to Snake in Japanese. According to Kojima, this made some of the proverbs redundant after translating them to English, since Mei Ling would be saying the same thing twice.

In Metal Gear Solid 2, Mei Ling is part of Philanthropy and assists in stealing equipment from the SSCEN, with Snake fearing for her safety. She makes a voiced cameo in the game as an easter egg during the Tanker chapter after the player has saved their progress thirteen times. In Metal Gear Solid 4, Mei Ling commands the museum-turned-training vessel USS Missouri and provides Snake and Otacon with backup through her connections with the SSCEN.

Outside of Metal Gear, she is a central character in the radio drama version of Metal Gear Solid and appears in the Game Boy Color version of Metal Gear Solid, as well as one of Snake's support crew members in Super Smash Bros. Brawl.

Mei Ling is voiced by Houko Kuwashima in Japanese and by Kim Mai Guest in English.

Johnny Sasaki

Johnny Sasaki (ジョニー佐々木, Jonī Sasaki) is a recurring character.

First appearing in Metal Gear Solid, he is a guard whose uniform is stolen by Meryl Silverburgh. Though unnamed in the game, he is named in the credits, with his surname coming from the game's character model designer, Hideki Sasaki. According to the developers' commentary in Metal Gear Solid: Integral, Hideki was known among the staff for his slackoff behavior and was included in the game as a running gag.

Johnny makes voiced cameos in Metal Gear Solid 2. In an early version of the game's story, his full name was Johnny Sasaki Slater (ジョニー・佐々木・スレイター, Jonī Sasaki Sureitā) and he was a spy for the Patriots, who would die from a pacemaker malfunction after coming in contact with Raiden. During the game, Raiden can hear Johnny talking using a directional mic in Big Shell.

In Metal Gear Solid 4, Johnny is known as Akiba (アキバ) and is a member of Meryl's Rat Patrol Team 01, with him and Meryl assisting Snake in Outer Haven by allowing him time to reach the server room. It is revealed that he had been in love with Meryl since he first saw her at Shadow Moses, and they marry in the epilogue. Unlike other soldiers in the Army and PMCs, Johnny does not have nanomachines due to his trypanophobia causing him to avoid the injections. While this has caused him to have frequent spells of colds and diarrhea and poor combat performance compared to his squad mates, he is immune to Liquid Ocelot's ability to directly attack soldiers' nanomachines. He also appears in the first Metal Gear Online expansion as a playable character.

Johnny Sasaki is voiced by Naoki Imamura in Japanese and by Dean Scofield in English. Akiba is voiced by Jun Fukuyama in Japanese and by Beng Spies in English.

Liquid Snake

Main article: Liquid Snake

Liquid Snake (リキッド・スネーク, Rikiddo Sunēku), real name Eli (イーライ, Īrai), is Solid Snake's twin brother, Big Boss's second son, and the main antagonist of Metal Gear Solid. In Metal Gear Solid, he is motivated by jealousy and hatred towards Snake and his desire to surpass his "genetic destiny" from Big Boss. A younger version of him is the main antagonist of Metal Gear Solid V: The Phantom Pain, dubbed the White Mamba (ホワイトマンバ, Howaito Manba). Liquid Snake is voiced by Banjō Ginga in Japanese and by Cam Clarke in English. The White Mamba is voiced by Yutaro Honjo in Japanese and by Piers Stubbs in English.

Sons of Big Boss

The Sons of Big Boss are a splinter group of FOXHOUND that appear in Metal Gear Solid. Led by Liquid Snake, they serve as the game's bosses.

Psycho Mantis

Main article: Psycho Mantis

Psycho Mantis (サイコ・マンティス, Saiko Mantisu) is a psychic expert for Liquid Snake's FOXHOUND unit in Metal Gear Solid. Following the collapse of the Soviet Union, he came to America in search of a job and worked with the KGB and the FBI before joining FOXHOUND. His special abilities include the psychic powers of psychokinesis and telepathy, which in a fourth wall-breaking scene allows him to identify certain games on the player's memory card and "move" the controller by making it vibrate. Due to being disgusted with his father's inner thoughts, he burned down his own village and started despising people. He also claims to be able to read the future, but this is implied through telepathy to predict his opponents' moves rather than clairvoyance. Mantis encounters Solid Snake twice; the first time, he takes control of Meryl Silverburgh's mind, and the second time he is killed after being unable to predict Snake's actions when the player uses the second controller port. His predictions also seem to be susceptible to change, as he states that Snake has a large place in Meryl's heart, but cannot see if their futures lie together.

In Metal Gear Solid 4, the original Mantis appears after Screaming Mantis's defeat, attempting to "read your mind" as before, but is unable to due to the advanced systems. He then tries to manipulate the controller, which, depending on the controller vibration available, either fails and infuriates him or succeeds and makes him scream in delight before he vanishes. Drebin later reveals that the Beauty and the Beast Corps had been under the control of Mantis.

The character's first chronological appearance is in Metal Gear Solid V: The Phantom Pain, where he is known as Tretij Rebenok (トリーチェゴ・レビョンカ, Torīchego Rebyonka, Третий ребёнок "The Third Child"). As a child, he was identified by Soviet researchers and taken to a facility in Moscow, where he was influenced by the Man on Fire's desire for revenge before they escaped and began working with Skull Face. He can detect electromagnetic currents running between the synapses of the brain and is particularly sensitive to feelings of anger, hatred and a desire for revenge. These feelings manifest in the physical world as a representation of those emotions, but he is easily overwhelmed by these emotions and becomes a slave to the will of who is expressing them. Throughout the story, he identifies these feelings as being strongest in the White Mamba and their relationship becomes symbiotic, magnifying his power and allowing the White Mamba to take control of Metal Gear Sahelanthropus. Once Snake disables Sahelanthropus, the boy steals a sample of a weaponized parasite designed to target English language speakers and passes it on to the White Mamba.

Psycho Mantis was polled as the 8th "Greatest Video Game Villain of All Time" by IGN and his boss battle being the 2nd Greatest Moment in Gaming. In the Japanese version, Psycho Mantis had been voiced by Kazuyuki Sogabe (in Metal Gear Solid), Hiroshi Yanaka (in Metal Gear Solid: Digital Graphic Novel) and Shōzō Iizuka (in Metal Gear Solid 4). Psycho Mantis is voiced by Doug Stone in the English translation.

Sniper Wolf

This section is about the Metal Gear character. For the YouTuber, see SSSniperWolf.

Sniper Wolf (スナイパー・ウルフ, Sunaipā Urufu) is a member of FOXHOUND and an elite sniper, who wields a Heckler & Koch PSG1 and uses mercury-tipped hollow-point bullets to poison her victims. She is also addicted to the drug diazepam.

Born in present-day Iraqi Kurdistan around 1983 during the Iran–Iraq War, when she was five years old she witnessed the death of her family and thousands of others from a chemical attack by Saddam Hussein's government troops against the rebellious Kurds. She was captured by Saddam's forces and taken as an orphan by the Iraqi Ministry of Interior, who brainwashed her and had a Gurkha sniper train her to be a child soldier for the government. Three years later, during the 1991 uprisings in Iraq, she fled to a Kurdish refugee camp, where Big Boss noticed her abilities and brought her with him to the United States, where she received counselling and deprogramming to remove her brainwashing. Out of gratitude, she followed him until his mutiny and death at the hands of FOXHOUND operative Solid Snake. She was then found by Liquid Snake, who convinced her to join a FOXHOUND splinter cell under his command.

In Metal Gear Solid, Sniper Wolf and Liquid Snake's group go rogue during the Shadow Moses Island incident, taking hostages and blackmailing the U.S. government with a hijacked walking tank while demanding that Big Boss' corpse be handed over to them. She cares for the huskies that Liquid intended to kill, as she enjoys their company. When Solid Snake infiltrates the island, Sniper Wolf wounds Meryl to lure him into a trap, capturing him so he can be tortured by Revolver Ocelot. After Snake defeats her in a sniper duel, he hears her life story and desire to be "set free" and kills her despite objections by Otacon, who professes his love for her. Snake also uses her handkerchief to avoid attacks by her wolves by masking his scent with hers. Sniper Wolf's ghost can be seen if the player uses the in-game photo camera on her body.

Sniper Wolf was originally planned to make a voice-over cameo appearance in Metal Gear Solid 2: Sons of Liberty during a conversation between Otacon and Olga Gurlukovich, and appears in a flashback sequence. Her spirit appears as a wolf in Metal Gear Solid 4: Guns of the Patriots, in which Crying Wolf engages in a sniper duel against Old Snake. Her costume can also be developed for Quiet in Metal Gear Solid V: The Phantom Pain.

A special Sniper Wolf character card appears in the non-canon spin-off game Metal Gear Acid 2 (2005). Other developers have also given homage-type nods to the character, such as with the "MGS Sniper Wulf Mk. II" item in EA Montreal's Army of Two and an "MG-S1 Sniper Wolfe" weapon in the PlayStation 3 version of Visceral Games' The Godfather II.

A 1/8 scale Sniper Wolf action figure was released by McFarlane Toys in 1998. Two 1/6 scale figures were also released only in Japan by Yamato (an action figure) and Studio Saru Bunshitsu (a garage kit). In 2012, Sniper Wolf was chosen by Konami as one of their 64 iconic characters to participate in the Konami E3 Battle event, where she lost against Metal Gear REX in the semi-final fourth round. A "bishōjo statue" designed by Shunya Yamashita based on Shinkawa's original picture was released by Kotobukiya in 2016.

After apparently defecting to the Soviet Union, she forces Naked Snake to kill her in a duel. It is revealed by EVA at the end of Snake Eater that The Boss's defection was a ploy to acquire the "Philosopher's Legacy" cache from Volgin's possession. However, Volgin's impromptu use of a Davy Crockett on Soviet soil led the United States government to turn The Boss into a scapegoat to avoid escalating the Cold War. The Boss is voiced by Kikuko Inoue in Japanese and by Lori Alan in English.

Volgin

Colonel Yevgeny Borisovitch Volgin (エヴゲニー・ボリソヴィッチ・ヴォルギン, Evugenī Borisovitchi Vorugin, Евгений Борисович Волгин), also known as as "Thunderbolt" in the West, is a Stalinist GRU colonel and the main antagonist of Metal Gear Solid 3: Snake Eater.

EVA

EVA (エヴァ) is Naked Snake's lover and Solid Snake's mother.

EVA intends to kill Major Ocelot to avoid revealing her cover, but Snake stops her. Later, she infiltrates Colonel Volgin's GRU base under the guise of Tatyana (タチアナ, Tachiana), Sokolov's supposed lover, and assists Snake; "Tatyana" is tortured by Volgin with electric shocks in order to coerce Sokolov into completing the Shagohod's development. During their missions, EVA and Snake began to develop feelings for one another and she helps him destroy the Shagohod, kill Volgin, and reach the Philosophers' Legacy so she can steal it. Volgin nearly kills her until The Boss volunteers to execute her personally, and after completing the mission, EVA and Snake have a one-night stand. However, she cannot bring herself to assassinate him and flees with half of the Philosophers' Legacy and intelligence data that would lead to the breakthrough in the Chinese nuclear weapons program. Soon after, Snake discovers a tape EVA left behind that details her secrets. The epilogue states that EVA disappeared in Hanoi, North Vietnam, during the Vietnam War in 1968.

She appears in Metal Gear Solid: Portable Ops as a recruitable character after completing a series of optional missions. In 1971, Big Boss and EVA reconcile after she was tracked down and rescued in Hanoi, and she was invited to become a founding member of a shadow government along with Zero, Para-Medic, Sigint, and Ocelot. At some point, she also discovered Ocelot's codename of ADAM, and the two reconciled. In 1972, EVA volunteered to serve as a surrogate mother in the "Les Enfants Terribles" project, despite Big Boss's disapproval of Zero's methods. She was originally implanted with eight clone fetuses, though six were aborted in order to encourage stronger growth in the remaining two: Solid Snake and Liquid Snake. EVA does not directly appear in Metal Gear Solid: Peace Walker, but remains in contact with Big Boss and gives cassette tape recordings to Militaires Sans Frontieres in 1974 that detail The Boss's final mission and the motivations behind her actions. She was entrusted to pass this on to Big Boss, and he eventually receives them.

In Metal Gear Solid 4: Guns of the Patriots, which is set in 2014, she appears under the identity of Big Mama (ビッグ・ママ, Biggu Mama) (also called Matka Pluku, Czech for "Mother of the Regiment") as the leader of the Paradise Lost Army resistance movement against Liquid Ocelot. It is revealed that she was fired from her job as a spy after failing a missions. She assists Snake in Eastern Europe and is injured during a chase after her motorcycle crashes, nearly burning to death. Snake saves her from Liquid Ocelot's gunshot, but the left side of his face is badly burnt in the process. She later dies from her injuries, but it is later revealed that the mutated FOXDIE virus carried in Snake's body killed her.

In Metal Gear Solid V: The Phantom Pain, Zero tasks EVA with arranging Big Boss's confinement at a hospital in Cyprus after XOF's attack on Mother Base.

EVA and Olga Gurlukovich's outfits can be used as costumes in Rumble Roses XX. EVA also makes a cameo appearance in Super Smash Bros. Brawl as an obtainable sticker, usable by Solid Snake in The Subspace Emissary.

EVA's character model was based by Hideo Kojima on a gravure idol he liked ("○○里", a possible reference to Chisato Morishita (森下 千里)), and her personality traits were inspired by Fujiko Mine from Lupin III. He also said: "On Eva's back are signs of torture. There are burn marks and cut marks, as well as some very old scars. The Colonel interrogated her with 'hentai play' (変態プレイ)." According to Kojima, EVA's character was disliked by the English voice actors for her personality.

In 2007, Tom's Games included her among the 50 greatest female characters in video game history, proposing that she should be portrayed in a live-action adaptation by "Uma Thurman, because she's tall, blonde and built to kick ass." In 2011, 1UP.com instead proposed Gillian Jacobs, adding that "EVA proved herself as one of the games' smartest and craftiest characters, playing heroes and villains alike like oversized flesh fiddles." The scene between the "sexy" EVA, Snake, and Ocelot in MGS3 was ranked as fifth on the 2010 list of the most Metal Gear amazing cutscenes by Joystick Division.

Para-Medic

Para-Medic (パラメディック, Paramedikku), also known as Dr. Clark (クラーク博士, Kurāku-hakase), is a FOX support team member that provides medical information. As Snake Eater is set before the modern use of the word "paramedic", her codename instead comes from a portmanteau of "parachute" and "medic". Para-Medic provides Naked Snake with information in Metal Gear Solid 3 and can later be recruited into the early FOXHOUND team in Portable Ops. Later games reveal that Para-Medic was the head of the "Les Enfants Terribles" project, and was responsible for Gray Fox's revival before being murdered by the first Cyborg Ninja. Originally, many believed that Dr. Clark was a man, which is later explained to be due to her secrecy concealing many details about her. Para-Medic is voiced by Houko Kuwashima in Japanese and by Heather Halley in English.

Cobra Unit

"Cobra Unit" redirects here. For other units named Cobra, see Cobra (disambiguation).

The Cobra Unit is The Boss's personal team of military specialists, who serve as the bosses of Metal Gear Solid 3. Each member is named after the primary emotion that they bring into battle.

The Pain

The Pain (ザ・ペイン, Za Pein) has the ability to control hornets through the buzzing of a queen hornet that he keeps in his backpack and wields a Tommy gun and grenades. He can use these hornets to shield himself and create a body double to confuse and draw his opponents into the open. The Pain is voiced by Hisao Egawa in Japanese and by Gregg Berger in English.

The Fear

The Fear (ザ・フィアー, Za Fiā) is a member of the Cobra unit known for his superhuman speed and agility and fearsome appearance. Capable of dislocating his joints at will, he has enhanced mobility and wields two crossbows, the Little Joe and the William Tell, coating their bolts in the venom of the Brazilian wandering spider, setting them on fire, or outfitting them with explosives. He uses a variety of wires and ropes to enhance his mobility and stealth camouflage to make himself nearly invisible. At the beginning of his battle in Metal Gear Solid 3, he shoots Naked Snake in the leg with a poisoned crossbow bolt, but wants to kill him himself rather than let the venom do the job for him. Though the poison begins to make Snake hallucinate, he manages to defeat him. The Fear is voiced by Kazumi Tanaka in Japanese and by Michael Bell in English.

The End

The End (ジ・エンド, Za Endo) is a member of the Cobra unit with exceptional sniping skills, born in the early 1860s, and the only member of the unit without an emotion-based codename, though it is explained in the game that it signifies "true oblivion". The End is a venerable expert sniper, but is vulnerable because of his age. However, he is capable of photosynthesizing sunlight to sustain himself and can go for days without food or water, explained in The Phantom Pain as the effect of a species of parasite that lives in his body. He has a pet Alexandrine parakeet who can alert him to Snake's presence. The End is the only member of the Cobras who will not kill the player under any circumstances; he only uses tranquilizing rounds and will throw Snake in a jail cell if he is defeated. The strategic sniper fight between Naked Snake and The End in Metal Gear Solid 3 was developed by Kojima, who wanted to bring a completely new style of boss battle to the series. However, the fight can be avoided if Snake kills a defenseless The End shortly beforehand, or if the player saves during the fight and waits a week or sets the system clock a week ahead, in which case The End dies of old age. In Peace Walker, The End's voice can be heard over the Codec during ghost missions, and Snake comments during mission briefings asking Kazuhira Miller if he saw any parrots with the enemy snipers and scouts.

The End is voiced by Osamu Saka in Japanese and by J. Grant Albrecht in English.

The Fury

The Fury (ザ・フューリー, Za Fyūrī) is a pyromaniac and former Soviet cosmonaut. He utilizes a flame-resistant Soviet space suit in conjunction with a jet pack and a powerful flamethrower, powered by the liquid rocket fuel UDMH.

The Sorrow

The Sorrow (ザ・ソロー, Za Sorō) was a spirit medium and former member of the Cobra unit, who used his psychic powers to aid his fellow soldiers on the battlefield. After being romantically involved with The Boss, he was the father of her child. After the ideological rift created by the Cold War, loyalties changed, with him and The Boss each taking their respective sides. The Boss reluctantly killed him in 1962 for making a double agent out of a sleeper agent she sent to OKB-1 to gather data on the USSR's space program. He makes many hidden appearances in ghost form throughout the game's cutscenes. In Metal Gear Solid 3, after escaping from Groznyj Grad and suffering a near-death experience, Naked Snake encounters The Sorrow while being forced to wade through an endless river swarming with the enemies that Snake has killed up to that point. The Sorrow is voiced by Yukitoshi Hori in Japanese and by David Thomas in English.

Raikov

The player is able to wear a mask to impersonate him, as Kojima noted that there were fans who wanted to play as Raiden in Metal Gear Solid 3. Besides impersonating Raikov, Naked Snake is required to incapacitate him and take his uniform to infiltrate Groznyj Grad, with the player also being given the choice of killing him. According to Kojima, the reason why he left Raikov's fate up to the player was largely because of Raiden's controversial popularity. Raikov appears as a secret character in Portable Ops, having been exiled to Colombia by the Soviet military after the fallout of Operation Snake Eater runs him afoul of the Kremlin.

Raikov is voiced by Kenyu Horiuchi in Japanese and by Charlie Schlatter in English.

Aleksandr Granin

Aleksandr Leonovitch Granin (アレクサンドル・レオノヴィッチ・グラーニン, Александр Леонович Гранин) is the director of OKB-812, also known as the Granin Design Bureau, and came up with the concept of bipedal walking tanks.

Johnny

Johnny is a GRU soldier assigned to watch over Naked Snake's jail cell in Groznyj Grad. Due to having an estranged son with the same name in America and claiming that all the first-born sons in his family are given that name, he is implied to be the grandfather of Johnny Sasaki. Johnny is voiced by Naoki Imamura in Japanese and by Michael Gough in English.

CIA Director

The Director of Central Intelligence is the one who planned Operation Snake Eater, leading Naked Snake to refuse to shake his hand during the award ceremony after returning from the mission. He also employed Ocelot as a triple agent within the CIA, KGB and GRU. In the end of Metal Gear Solid: Portable Ops, Ocelot betrays the DCI under orders from a new employer and kills him in order to obtain the location of the Philosopher's Legacy. In Japanese, the DCI is voiced by an uncredited actor in Metal Gear Solid 3 and by Masaharu Sato in Portable Ops.

He bears the likeness of Robert McNamara, though was rewritten to be the Army Chief of Staff in Metal Gear Solid: Peace Walker. He makes an unvoiced appearance in the end of Metal Gear Solid: Portable Ops, where he attends FOXHOUND's inauguration ceremony. In Peace Walker, he is now the Chairman of the Joint Chiefs of Staff and contacts Big Boss when Peace Walker relays false nuclear launch data. He is the only member at the DEFCON meeting who believes Big Boss when told that the nuclear launch data is false after the latter provides proof, but is held at gunpoint by the other executive members when he orders them to stand down from retaliating. Despite this, Big Boss succeeds in stopping a retaliation strike from being launched.

Jonathan (ジョナサン, Jonasan) is one of the Red Army soldiers stationed at the San Hieronymo base and the first of the enemy soldiers to be recruited by Naked Snake's early FOXHOUND group. After meeting Snake and Roy Campbell, Jonathan says that the Red Army personnel were assigned to build the base as an alternate strategic missile site after the Cuban Missile Crisis; détente and the USSR's commitment to the SALT negotiations resulted in the abandonment of the base, leading the soldiers to join Gene. Jonathan is left impressed with Snake's idealism and helps in treating Campbell's bout with malaria. As Gene manipulates the Soviet soldiers into killing each other, Jonathan dies in Snake's arms after protecting him from bullets, shaping the ideals and principles that he came to uphold as Big Boss.

Python (パイソン, Paison) is one of FOX's original members, who worked alongside Naked Snake during the early stages of the United States' advisory effort in Vietnam. However, he was severely injured during a mission with the Civilian Irregular Defense Group, losing the ability to regulate his body temperature. The United States government operated on him to stabilize his body temperature, eventually putting him in a Sneaking Suit filled with liquid nitrogen, with several needles in his head to vent excess heat. The CIA uses him as a counterpart to Snake in case he rebelled. Python allies with the player if he is defeated by non-lethal means, but will burn to death if he is killed. Python is voiced by Yûsaku Yara in Japanese and by Dwight Schultz in English.

Elisa (エルザ, Eruza) and Ursula are split personalities of a teenage girl raised in East Germany to nuclear physicists who worked in the USSR. She is revealed to be a survivor of the 1957 Kyshtym disaster, with the radioactive fallout triggering her psychic abilities, and underwent numerous ESP and psychic tests after returning to East Germany. The testing enabled her to create split personalities that people can mistake as twins due to their different hair colors: Elisa has gold hair, while Ursula's hair is silver. Gene rescued her during a mission in 1966 and trained her personas – Elisa in medicine and Ursula in combat abilities. Over the course of the game, Elisa helps Naked Snake. However, Ursula appears during Snake's showdown with Metal Gear RAXA and attempt to Gene, resulting in "their" deaths.

In Metal Gear Solid: Peace Walker, he and Strangelove build the Peace Sentinels' AI weapons for Hot Coldman and MSF's own Metal Gear ZEKE for Naked Snake. In a personal letter he writes to Strangelove and asks Snake to deliver, it is revealed that they worked together at NASA and Huey expressed interest in Strangelove.

Huey remains with Big Boss and MSF during Metal Gear Solid V: Ground Zeroes, working to hide MSF's nuclear capabilities from the United Nations. He is present when MSF is attacked by the XOF forces, though Metal Gear Solid V: The Phantom Pain confirms that Emmerich managed to escape and developed a cybernetic lower exoskeleton to walk again. Emmerich maintains that he was misled by Cipher and abducted to work on the new model Metal Gear Sahelanthropus in Afghanistan for Skull Face, where he is rescued and detained by Diamond Dogs. He resumes his work for Diamond Dogs, but faces interrogation and lingering doubts about his allegiances, coming to view Diamond Dogs as being no different from Coldman or Cipher. Emmerich is accused by Diamond Dogs of murdering Strangelove and facilitating the attack on MSF for Cipher in exchange for his own safety, and is found guilty of triggering a new mutation in the vocal cord parasites that results in Venom Snake being forced to execute his own men.

Due to bitterness over his demotion, Coldman plans to use the Peace Sentinels and the Peace Walker Project to regain his status as a power player in Washington. The true reason behind his exile was because he planned Operation Snake Eater. Coldman believes that nuclear deterrence is a flawed theory, claiming humans will not retaliate during a nuclear strike due to fear of destroying themselves. He also believes that with impartial artificial intelligence, Peace Walker would guarantee retaliatory nuclear strikes against any nuclear power, ensuring true deterrence and worldwide peace. Coldman dies after being shot by Zadornov, but not before inputting Peace Walker's nuclear launch codes and leaking false data to NORAD of an impeding USSR nuclear strike against the United States. However, he is proven wrong, as senior members of NORAD planned to retaliate against the USSR. Coldman is voiced by Mugihito in Japanese and by H. Richard Greene in English.

He and his student, Paz Ortega Andrade, visit the Militaires Sans Frontières' base in Colombia to recruit MSF's services, and he assists the MSF as they uncover the Peace Sentinels' motives in Costa Rica. He later unmasks himself as a KGB intelligence operative when Coldman prepares the Peace Walker to attack the MSF's Mother Base from inside a United States base in Nicaragua. Zadornov plans to use Peace Walker to launch a nuke at Cuba and blame the attack on the United States, which would lead to communism spreading throughout Central America. The MSF and FSLN capture him and incarcerate him at Mother Base, but he breaks out and forces Big Boss to recapture him before he kills him in self-defense. Vladimir Zadornov is voiced by Hōchū Ōtsuka in Japanese and by Steven Blum in English.

In Peace Walker, her experience with The Boss and subsequent work in ARPA inspires her to create the Mammal Pod as Peace Walker's AI matrix with The Boss's personality, which initially puts her at odds with Naked Snake. However, Strangelove later joins MSF and helps create Metal Gear ZEKE's AI matrix. In Ground Zeroes, she leaves MSF a week before the IAEA inspection notification arrived due to the AI department being free of suspicion. The Phantom Pain reveals that she retrieved the Mammal Pod to use as a basis for Zero's AI system. After she opposed Huey's attempts to use Hal as a test subject for Metal Gear Sahelanthropus, she was locked inside the Mammal Pod to suffocate. Strangelove is voiced by Yumi Kikuchi in Japanese and by Vanessa Marshall in English.

Cécile was influenced by the May 1968 events in France, similar to other Parisian women at the time. The way her name is pronounced is a play on the phrase Kojima, kami nan desu (小島、神なんです, "Kojima, he's definitely a god"). She is named after and visually based on Cécile Caminades, an employee from the Paris branch of Konami Digital Entertainment.

Cécile Caminades is voiced by Yū Kobayashi in Japanese and by Catherine Taber in English.

Paz

Paz Ortega Andrade (パス・オルテガ・アンドラーデ, Pasu Orutega Andorāde) is a schoolgirl at the University of Peace.

First introduced in Peace Walker, she is the apparent student of Ramon Galvez Mena, who recruits the Militaires Sans Frontières in Costa Rica to survey Coldman's Peace Sentinel AI experiments. In the game's true ending, she is revealed to be Pacifica Ocean, an agent of Cipher. Paz hijacks Metal Gear ZEKE and attempts to launch a nuclear warhead at the American East Coast, with the intention of framing MSF as being an extremist cult under Cipher's orders. Big Boss defeats her and she is thrown into the water from the force of ZEKE's explosion, although Big Boss suspects that she may have survived. Paz provides commentary about her deep-cover mission in a ten-part series of audio tapes called "Paz's Diary, in which she discusses life in Mother Base and her fears of a strong reprisal from Cipher if she blows her cover.

Paz returns in Ground Zeroes and The Phantom Pain, where she is revealed to have survived. She is rescued by Skull Face's XOF group and brought to Camp Omega, undergoing interrogation and torture and the surgical implanting of explosive devices in her abdomen and womb. Big Boss retrieved her and Chico from the camp, believing her to be instrumental in finding and stopping Cipher. During their rescue, Big Boss and Chico discover the surgical scars from one bomb inside Paz's body, which Venom Snake is forced to remove. While trying to escape XOF's assault on MSF, Paz reveals the second bomb before throwing herself from the helicopter in an attempt to save the others from the subsequent explosion, which kills her. She seemingly survives and is brought back to Diamond Dogs, but has amnesia due to dissociative identity disorder, leading her to forget about Cipher and believe herself to still be a student in 1974. After removing a bomb from her stomach in front of Snake, he realizes that she is just a hallucination stemming from guilt over not being able to save her and comes to terms with her death.

Paz is voiced by Nana Mizuki in Japanese and by Tara Strong in English.

She is killed by Raiden during a mission in Abkhazia after being doused in liquid nitrogen. Mistral is voiced by Romi Park in Japanese and by Salli Saffioti in English.

Monsoon

Monsoon (モンスーン, Monsūn) is the third member of the Winds of Destruction, named after the seasonal wind systems that occur in West Africa and Australasia, in addition to being born in Cambodia. He has the ability to magnetically dislocate segments of his body to attack from a distance and wields smoke grenades and a pair of sai known as "Dystopia". His personality is that of a nihilistic, misanthropic sociopath, which is implied to be the result of trauma from Khmer Rouge's reign of terror. He is killed by Raiden during the latter's assault on World Marshal's headquarters. Monsoon is voiced by Masashi Ebara in Japanese and by John Kassir in English.

Blade Wolf

Blade Wolf (ブレードウルフ, Burēdourufu), initially known as IF Prototype LQ-84i, is an unmanned AI weapon in Desperado's arsenal. When Raiden defeats the machine, Doktor rebuilds it as Raiden's ally. After nearly being destroyed by Armstrong, it comes to live with Sunny at SOLIS. An additional chapter released as downloadable content details part of Blade Wolf's history with Desperado prior to its first encounter with Raiden. Blade Wolf is voiced by Yoshimasa Hosoya in Japanese and by Michael Beattie in English.

Khamsin

Khamsin (カムシン, Kamushin) is an unofficial fourth member of the Winds of Destruction, who appears in the Blade Wolf DLC chapter, named after a hot, dry, dusty south–north wind in North Africa and the Middle East. He was discharged from the Marines due to friction between him and his teammates, and is held in similarly low regard by Desperado. His body from the waist down is replaced with connectors to a large mech suit,, and he wields a chainsaw/battle-axe. Blade Wolf is manipulated by Mistral into killing Khamsin, whom she believes to be a problem. Khamsin is voiced by Rikiya Koyama in Japanese and by Benito Martinez in English.

Senator Armstrong

Main article: Senator Armstrong (Metal Gear)

Steven Armstrong (スティーヴン・アームストロング, Sutīvun Āmusutorongu) is a Colorado senator, the primary backer of Desperado and World Marshal, and the main antagonist of Metal Gear Rising: Revengeance. He seeks to be elected as president of the United States in order to rebuild it from within, purging those too weak or impoverished to contribute to society. He uses nanomachines to enhance his strength and transform parts of his skin into metallic armor, reducing the effectiveness of attacks. Though he attempts to use Metal Gear EXCELSUS to assassinate the US president in Pakistan, EXCELSUS is destroyed by Raiden, who ultimately kills him. In the Jetstream DLC, Armstrong is revealed to be the one who cut off Sam's arm. Steven Armstrong is voiced by Unsho Ishizuka in Japanese and by Alastair Duncan in English.

Introduced in Metal Gear Solid V: The Phantom Pain

Venom Snake

Venom Snake (ヴェノム・スネーク, Venomu Sunēku), also known as Punished Snake (パニッシュド・スネーク, Panishudo Sunēku), is Big Boss's body double. He is an unnamed combat medic in Metal Gear Solid V: Ground Zeroes and the player character in Metal Gear Solid V: The Phantom Pain. In 1975, he was among Big Boss's Militaires Sans Frontières private forces. During a helicopter extraction at a U.S. Naval prison facility in Cuba, he removed a time bomb within Pacifica Ocean and shielded Big Boss from a bomb, resulting in the loss of his left arm and fragments of bones, teeth, and a large piece of shrapnel lodged within his cerebral cortex. They fall into a coma for nine years and are transferred to a hospital in Cyprus, where he was subjected to Zero's subconscious brainwashing and facial reconstruction as a mental doppelgänger who awakens in 1984 and draws attention away from Big Boss. Snake takes command of the Diamond Dogs mercenary unit as revenge for fallen comrades with a "Mother Base" near Seychelles, with Kazuhira Miller and Revolver Ocelot as advisers. Snake engages in missions in Afghanistan and Central Africa as he recruits several companions and deals with the Cipher organization's remnants, ultimately confronting Skull Face and the XOF strike force, as well as Huey Emmerich and White Mamba. Some time later, he receives a cassette tape labeled "Operation Intrude N313", which he plays on a Sony BitCorder device connected to a HiTBiT MSX2 computer before he dies fighting in Outer Heaven. Venom Snake is voiced by Akio Ōtsuka in Japanese and by Kiefer Sutherland in English.

Skull Face

Skull Face (スカルフェイス, Sukaru Feisu) is the main antagonist of Metal Gear Solid V: Ground Zeroes and Metal Gear Solid V: The Phantom Pain. The commander of the mysterious XOF special-forces unit, his identity and nationality are initially unknown, and he claims to have forgotten his native language, though can speak Hungarian and is later revealed to have been born in Transylvania before it was returned to Romanian control. Unable to establish a consistent identity, Skull Face came to resent cultural imperialism and Cipher's ideology. The injuries that resulted in his appearance were sustained when a rapeseed oil factory his parents worked in was bombed on suspicion of manufacturing weapons, after which he was taken to the Soviety Union and subjected to an early form of "parasite therapy", in which parasitic organisms were introduced into his body to keep him alive. He was later infected with one of Code Talker's parasites, making it impossible for him to speak his native language. He eventually became a spy and assassin specializing in poisons, killing Joseph Stalin as revenge for the subjugation of Romania. Skull Face considers the bombing to have burned the humanity out of him, and tortures his captives to the brink of death in order to witness their hope being extinguished, believing that he can discover the source of his own hope and regain his humanity.

Initially, Skull Face became an agent of the XOF organization created by Zero to provide intel and support during missions, but grew resentful of Zero's fame while Cipher kept him in the shadows. By Ground Zeroes, he is a senior operative working on behalf of Cipher; he expresses dissatisfaction with Zero's leadership and seeks information that will lead him to Zero. As the commander of XOF, he authorizes and participates in the torture and imprisonment of Paz and Chico, latering leading an assault which results in the partial destruction of Big Boss's Militaires Sans Frontières. By The Phantom Pain, Skull Face has fallen out of favor with Cipher and exiled to Africa, where he revives a project designed to weaponize a parasite as a form of ethnic cleansing, as it targets and kills speakers of different languages. He uses the project to develop a strain of vocal-cord parasite that targets English speakers, intending to unleash it against Cipher and start a new Cold War by giving easy-to-make nuclear weapons to minority groups. To do this, he activates the unfinished Metal Gear ST-84 "Sahelanthropus", but is betrayed and left crushed under a broken girder while Venom Snake neutralizes the ST-84. Skull Face accepts his defeat, apparent by his quoting of David Bowie's "Space Oddity". However, he is incapacitated and begs to be killed, buSnake and Kazuhira Miller shoot him, detaching his right arm and left leg, before leaving him to die. After Dr. Emmerich kills him with a gunshot, his remains are cremated when the parasites within still exhibit life signs in order to kill him for good.

Skull Face is voiced by Takaya Hashi in Japanese and by James Horan in English.

Quiet

Main article: Quiet (Metal Gear)

Quiet (クワイエット, Kuwaietto) is a sniper who appears in the prologue as part of a team attempting to kill Big Boss when he is discovered by Cipher, but suffers severe third-degree burns and is kept alive through parasite therapy that gives her the ability to photosynthesize light, breathe through her skin, cloak herself, and move with superhuman speed and strength. After being defeated by Venom Snake in open combat, she is brought back to Mother Base and begins participating in missions with Snake. As their relationship develops, she is infected with the English-language strain of vocal-cord parasites as a means of assassinating Snake, demanding her silence in order to prevent her symptoms from showing. Although the Diamond Dogs cure the infection, Quiet refuses the treatment due to her latent desire for revenge. However, following the mutation of the parasite, she realizes that her silence is not enough to prevent symptoms from spreading and allows herself to be captured by Soviet forces in Afghanistan. Though Snake rescues her, they are lost in a sandstorm as Soviet forces hunt them down, prompting Quiet to speak English to direct a helicopter to their location, awakening the parasite. After leaving a goodbye message to Snake, she disappears in the Afghan desert to prevent the infection from spreading. Dutch model Stefanie Joosten provided Quiet's likeness, motion capture, and voice.

Code Talker

Code Talker (コードトーカー, Kōdo Tōkā) is a Navajo biologist who specializes in parasite research. Born in 1880, he has survived for over a century due to his research, in which he identified and injected himself with the same species of parasite that gave The End his powers and longevity. Code Talker was ordered by Skull Face to duplicate the vocal cord parasite for use in his plan under the threat of the extermination of his people. He was later rescued by the Diamond Dogs and brought back to Mother Base to aid in finding a way to prevent or cure the parasite. Code Talker is voiced by Osamu Saka in Japanese and by Jay Tavare in English.

Skulls

The Parasite Unit (パラサイトユニット, Parasaito Yunitto), also known as the Skulls (スカルズ, Sukaruzu), are an elite force of supersoldiers working for XOF. They possess glowing turquoise eyes thanks to a strain of Code Talker's parasites, which grants them enhanced abilities at the cost of their cognitive functions; these abilities include optical camouflage, corrosive gas dispersal, shapeshifting, and rock-like metallic armor.

D.D.

D.D., short for Diamond Dog, is a trained wolf who assists Diamond Dogs in The Phantom Pain. Venom Snake finds him in Afghanistan as an orphaned puppy and brings him back to Diamond Dogs, where Ocelot trains him to provide support on missions.

Groups and organizations

Outer Heaven

Outer Heaven (アウターヘブン, Autā Hebun) is the manifestation of Big Boss's ideology throughout the Metal Gear titles.

The original iteration is a nation-state that serves as the original Metal Gear game's setting, located 200 kilometers north of the Garzburg, South Africa. A mercenary financed the nation's establishment to attract disillusioned soldiers, with a massive fortress as its centerpiece. Its potential threat to world affairs is boosted with the deployment of the TX-55 Metal Gear. In the game, FOXHOUND commander Big Boss orders Solid Snake to infiltrate the mercenary state and destroy Metal Gear. After Snake defies expectations and destroys Metal Gear, the nation's apparent leader confronts Snake but is defeated, with Outer Heaven destroyed as well.

In Metal Gear 2: Solid Snake, the fortified nation of Zanzibar Land (ザンジバルランド, Zanjibaru Rando) in Central Asia declares themselves a nuclear power thanks to Metal Gear D provided by Big Boss, but his former subordinate infiltrates Zanzibar and defeats Metal Gear and Big Boss.

Subsequent concepts of the ideology continue in the first two Metal Gear Solid games, where Liquid Snake's FOXHOUND takes over Shadow Moses Island in Metal Gear Solid to threaten the world with Metal Gear REX, and Solidus Snake enacts a plan in Metal Gear Solid 2 to detonate an electro-magnetic pulse in New York to destroy the Patriots' AI systems; both plans are foiled by Solid Snake and his allies.

Outer Heaven's origins are depicted in Metal Gear Solid: Portable Ops as Naked Snake's response to Gene's "Army Heaven"; the former is given data, resources, and personnel after the latter's defeat.

A new iteration appears in Metal Gear Solid 4: Guns of the Patriots as Liquid Ocelot's mother company that runs five PMCs: Praying Mantis, Pieuvre Armement, Raven Sword, Werewolf, and Otselotovaya Khvatka thanks to a weak-spot within the Patriots' AI network. After Old Snake and Otacon use the FOXALIVE virus to destroy the Patriots, Ocelot believes that Big Boss's dream has finally been achieved.

FOXHOUND

"FOXHOUND" redirects here. For other uses, see Foxhound (disambiguation).

High-Tech Special Forces Unit FOXHOUND (ハイテク特殊部隊フォックスハウンド, Haiteku Tokushu Butai Fokkusuhaundo), alternatively spelled "FOX-HOUND" or "FOX HOUND", is a US Army elite special forces unit. FOXHOUND was originally established in 1990 to cope with local revolutions, regional complications, and global terrorist activities; Metal Gear Solid 3 would later retcon the year FOXHOUND was established, stating in the ending timeline that FOXHOUND was established in 1971. The unit specializes in black ops, carrying out top-secret operations within "unauthorized" combat zones that are too politically sensitive to intervene in through conventional means. In the MSX2 versions of Metal Gear and Metal Gear 2, FOXHOUND members are often referred to as "FOX HOUNDERS", although this term fell into disuse in later versions.

In the original Metal Gear, FOXHOUND has Big Boss as the team's commanding officer while Solid Snake and Gray Fox serve as field operatives. However, Big Boss betrays the unit by the end of the game. In Metal Gear 2: Solid Snake, Roy Campbell goes from the unit's executive officer to the new commanding officer, while drill instructor Master Miller and military strategist George Kasler form part of Solid Snake's support crew in the game.

The FOXHOUND unit turns rogue in Metal Gear Solid as the Sons of Big Boss (ビッグ・ボスの息子たち, Biggu Bosu no Musuko-tachi) under Liquid Snake's leadership (Revolver Ocelot, Psycho Mantis, Sniper Wolf, Vulcan Raven and Decoy Octopus), involved in a terrorist revolt on Shadow Moses Island in hopes of threatening theworld with Metal Gear REX as a second "Outer Heaven". However, they are defeated/killed by Solid Snake with help from Otacon, the Cyborg Ninja, and Meryl Silverburgh. The unit is subsequently disbanded; however, Raiden believes himself to be in the service of a new version in Metal Gear Solid 2 under the command of an AI fascimile of Campbell controlled by the Patriots, and Meryl Silverburgh wears FOXHOUND's shoulder sleeve insignia in Metal Gear Solid 4 as the leader of Rat Patrol Team One (ラットパトロールチームワン, Ratto Patorōru Chīmu Wan), composed of Johnny, Ed and Akiba.

Outside the Metal Gear series, FOXHOUND is mentioned in Snatcher as a military unit that JUNKER Chief Benson Cunningham previously served, and in Policenauts as Meryl's former unit.

The Patriots

The Patriots (愛国者達, Aikokushatachi), also referred to as the La-li-lu-le-lo (らりるれろ, Rarirurero), are a secret cabal that controls the United States. The group is initially believed to be led by an inner circle of twelve people known as the Wisemen's Committee (賢人会議, Kenjin Kaigi).

In Metal Gear Solid 2, the Patriots manipulate the story's events. During the Tanker incident, they begin a smear campaign against Snake to frame his organization Philanthropy for an oil tanker's destruction in New York. During the Big Shell incident, Solidus Snake leads the Sons of Liberty (自由の息子達, Jiyū no Musuko-tachi), consisting of Revolver Ocelot, Olga Gurlukovich and the Dead Cell members, to take over Arsenal Gear. As it houses the AI GW to censor the flow of digital information as a third "Outer Heaven", they plan to use the Metal Gear RAY on New York to trigger an electromagnetic pulse and permanently destroy the Patriots' AI systems. However, the Patriots manipulated agents to ensure their demise by Solid Snake and Raiden. Philanthropy later acquires a disk containing the identities of the Wisemen's Committee and learns that itsmembers have been dead for "about a hundred years".

Metal Gear Solid 4 revealed that the Patriots were created from Zero's paranoia in the form of four computer AIs: TJ, TR, AL and GW, controlled by a fifth proxy AI, JD. The AIs were originally created to carry out Zero's will due to his age and skepticism that human subordinates would be able to do so. However, over time, the system evolved from its original purpose to create a new world order based on war economies. The Patriots' network is shut down when Naomi Hunter's and Sunny's FOXALIVE computer worm uses GW as a conduit to access the others.

The Patriots' AI in Metal Gear Solid 2 is voiced by Takeshi Aono and Kikuko Inoue in Japanese and by Paul Eiding and Lara Cody in English.

Philanthropy

Philanthropy (フィランソロピー, Firansoropī) is a U.N.-recognized anti-Metal Gear non-governmental organization in Metal Gear Solid 2. Its primary members consist of Solid Snake, Hal Emmerich, and Mei Ling. A large amount of the startup funds for the organization were provided by Nastasha Romanenko. Being an NGO, while the U.N. recognizes its existence, it has no official government backing. As Philanthropy is a semi-clandestine organization, Otacon must sometimes obtain equipment and information through less-than-legal methods; Snake mentions that on more than one occasion, Otacon has hacked classified networks to 'appropriate' experimental technology. In addition, it was also involved in activities comparable to terrorism.

The Philosophers

"The Philosophers" redirects here. For the person who studies general and fundamental problems, see Philosopher. For the 2013 film, see The Philosophers (film).

The Philosophers (賢者達, Kenjatachi) were an inner circle consisting of the Wisemen's Committee's members, which was formed at the end of World War I when the leaders of the United States, China, and Bolshevik Russia entered a secret pact to pool money and rebuild countries affected by the war. The group's amassed amount totaled 100 billion dollars to fund war efforts and research; this sum became known as the "Philosopher's Legacy". After the original members' deaths during the 1930s, their followers began infighting to inherit the fund left by the original members. In Metal Gear Solid 3, Volgin uses the Philosopher's Legacy to create the fortress Groznyj Grad (グロズニュ・グラード, Gurozunyu Gurādo, Грозный Град) within the Soviet branch, with the Shagohod and The Boss as collateral. Naked Snake retrieves the Philosophers' Legacy after the defeats of Volgin and The Boss for the American branch; however, EVA manages to obtain the data for the Chinese branch. The game's ending timeline establishes that a reorganized American branch of the Philosophers, which later becomes Cipher, is formed after accumulating the missing funds; Metal Gear Solid: Portable Ops instead shows Ocelot killing the DCI to end the Philosophers and obtain documents containing the Philosophers' identities and the location of the organization's funds.

FOX

The FOX unit (FOX部隊, Fokkusu Butai, which stands for "Force Operation X") is introduced in Metal Gear Solid 3 as Zero's special forces unit, with Naked Snake as its first agent and Para-Medic and Sigint as additional support. The FOX unit turns renegade in Portable Ops under Gene's ultimate goal of Army's Heaven (アーミーズヘブン, Āmīzu Hebun) that victimizes soldiers in pursuit of Gene's goals. In response, Naked Snake and Roy Campbell form their own team of specialists which goes on to become the FOXHOUND unit. Big Boss wears the FOX unit's shoulder sleeve insignia on the right side of his uniform in Peace Walker and Ground Zeroes.

A covert strike force, XOF, appears in Metal Gear Solid V under Skull Face's leadership. Originally a support network for FOX, XOF secretly continued as a black ops division of Cipher before having gone rogue, as shown when they remove any identifying markings from both personnel and equipment in Ground Zeroes. After carrying out a successful assault on MSF's Mother Base, XOF are eventually destroyed by the Diamond Dogs led by Venom Snake in The Phantom Pain.

FOX's insignia is a stylized yellow fox on a black background, while XOF's insignia is a black fox on a yellow background.

MSF

Militaires Sans Frontieres (国境なき軍隊, Kokkyō Naki Guntai, translated as "Soldiers Without Borders") is Naked Snake's mercenary group in Metal Gear Solid: Peace Walker. Their name is a play on that of the real-world humanitarian-aid NGO Médecins Sans Frontières, dedicated to assisting countries ravaged by war and epidemics that are in need of doctors and medical experts. The HD Edition version of Peace Walker displays an announcement before the title screen, stating that the fictional mercenary group is not in any way linked to the real group. Despite this, the group is never mentioned by name in Metal Gear Solid V and the unit's emblem was modified to omit its name. MSF's logo is a skull stylized after Pangaea inside a yellow and black circle.

Per The Boss's will, Snake conceptualized MSF as capable of providing combat support to any individual or country, regardless of other factors. Kazuhira Miller helps develop MSF into a private military contractor offering a wide range of services on their Mother Base (マザーベース, Mazā Bēsu) in the Caribbean Sea, thanks to Vladimir Zadornov and Paz Ortega Andrade during Coldman's Peace Sentinel takeover within Costa Rica and later the MSF's own housing of Metal Gear ZEKE. Metal Gear Solid V: Ground Zeroes shows that the MSF unit is all but gone after the mysterious XOF organization attacks; many of the MSF personnel on assignment at the time of the attack return right away, are disheartened by Big Boss's apparent death, and later move on to work in other mercenary outfits. The group is renamed "Out Of Order" in the Japanese language novelizations of Peace Walker and The Phantom Pain authored by Hitori Nojima, and appears in the subtitles for the Japanese version of The Phantom Pain but is never spoken by the actual characters.

Cipher

Cipher (サイファー, Saifā) is an American covert intelligence agency that served as the Philosophers' reorganized American branch and the Patriots' precursor. The group is officially mentioned in Metal Gear Solid: Peace Walker and referenced throughout most of Metal Gear Solid V: Ground Zeroes and Metal Gear Solid V: The Phantom Pain. The organization was initially formed by Zero alongside Big Boss to fulfill The Boss's ideal unified world. A fallout occurred where Big Boss and Zero interpreted The Boss's will differently; Big Boss believed wanted a world where soldiers were not used as government tools with Revolver Ocelot and EVA as support, whereas Zero took to control of the entire world to ensure unification which would eventually grow too corrupt. as seen with Donald Anderson and Dr. Clark, and having Pacifica Ocean oppose MSF via Metal Gear ZEKE, and ends up disorganized by Skull Face's ambitions.

Diamond Dogs

The Diamond Dogs (ダイアモンド・ドッグズ, Daiamondo Dogguzu) are a splinter organization made from MSF's surviving remnants under Venom Snake's command in Metal Gear Solid V: The Phantom Pain. The Diamond Dogs is based out of a new Mother Base in the Seychelles, given out of gratitude for their assistance in fighting off a coup, with Kazuhira Miller and Revolver Ocelot as second in command. The Diamond Dogs' logo consists of a profile shot of a Rhodesian Ridgeback dog overlaid upon a cut diamond, finished off with a yellow scroll featuring the words "Diamond Dogs".

Reception

The characters from the Metal Gear series have been well received by gamers, with Solid Snake and Raiden appearing in a Famitsu poll that listed the fifty best video game characters; while the former was at the top, the latter was 42nd. Solid Snake has also appeared in multiple lists of best characters in gaming history, while Raiden and Revolver Ocelot were found as characters who should have their own spin-off games. While the variety of characters have been noted, publications often found some out of place as a result of their abilities and confusing changes occurring within them. The characters have also been praised for their actions within fight scenes, resulting in appealing cutscenes.

The bosses have been praised not only for the requirements for defeating them, but also for the importance they have within the story. Various video game publications have made feature articles regarding who is the best boss character within the series, but results have varied. During 2004, The Boss was awarded "Best New Character" by GameSpot for her role in Metal Gear Solid 3: Snake Eater. In 2013, GamesRadar praised the character roles of Revolver Ocelot/Liquid Ocelot, Psycho Mantis, The Boss, and Steven Armstrong, placing them in their list of 100 best villains in video games.
