Otacon '''''', nicknamed , is Solid Snake's close friend, an employee of ArmsTech, and Metal Gear REX's engineer, who later becomes a founding member of the non-profit Philanthropy organization. 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,
educating himself 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, 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 the lead engineer for Metal Gear REX. 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. Otacon next appears in
Metal Gear Solid 2: Sons of Liberty. In 2007, he 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 and is popular with women, but keeps them at arm's length due to Naomi's death leaving a lasting impact on him. Otacon is voiced by
Hideyuki Tanaka in Japanese and by
Christopher Randolph in English.
Meryl Silverburgh '''''' 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 personal 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 '''''', called by her staff, is a
geneticist by practice 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. 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 Naomi Hunter is voiced by
Hiromi Tsuru in Japanese and by
Jennifer Hale in English.
Mei Ling '''''' 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. Outside of
Metal Gear, she is a central character in the
radio drama adaptation 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 and
Super Smash Bros. Ultimate. Mei Ling is voiced by
Houko Kuwashima in Japanese and by
Kim Mai Guest in English.
Johnny 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 main 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. During the game, Raiden can hear Johnny talking using a directional mic in Big Shell. 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 appears in
Metal Gear Solid V: The Phantom Pain, dubbed the . 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.

Psycho Mantis '''''' 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 do so 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 . 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 Japanese, Psycho Mantis has 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). In English, Psycho Mantis is voiced by
Doug Stone.
Sniper Wolf '''''' 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

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.

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 and based on Shinkawa's original picture was released by Kotobukiya in 2016. Sniper Wolf is voiced by Naoko Nakamura in Japanese and by
