Naomi Hunter
"Voiced by: Hiromi Tsuru (JP), Jennifer Hale (EN)"

A geneticist with a past even she's not completely sure of, Naomi was chosen to support Snake during the Shadow Moses mission to provide feedback on the Genome Soldiers. She had her own agendas, which included.

Naomi returns and redeems herself in the fourth game where she helps Old Snake deal with Liquid Ocelot and forms a close relationship with Hal and Sunny. -
 * Absolute Cleavage: In MGS4.
 * Hey Its That Voice: She and Emma Emmerich share the same voice actress.
 * Hot Scientist
 * in the fourth game.
 * Intergenerational Friendship: With Sunny in MGS4.
 * Inconsistent Dub: In the original English version of Metal Gear Solid, Naomi was given a vaguely British sounding accent. When the dialogue was redubbed for the GameCube remake, Naomi was given a more neutral accent which was also used for Metal Gear Solid 4. Actually, she's from Rhodesia/Zimbabwe.
 * Ironic Hell: Her . The Patriots also took note of this, as they had her imprisoned for doing that action.
 * Known Only By Their Nickname: It is strongly implied that she is not actually named "Naomi Hunter" (Miller/ mentioned that she stole the identity papers of the "Real Naomi Hunter" at one point). Likewise, even she doesn't know her real name.
 * Tall Dark and Bishoujo
 * TV Genius: She's a geneticist, but she still knows a lot about computers and hacking if the fourth game is to be believed...
 * What the Hell Hero: She calls out Snake for his role in Gray Fox's situation, which also acted as one of the reasons for.
 * Tall Dark and Bishoujo
 * TV Genius: She's a geneticist, but she still knows a lot about computers and hacking if the fourth game is to be believed...
 * What the Hell Hero: She calls out Snake for his role in Gray Fox's situation, which also acted as one of the reasons for.

Mei Ling
"Voiced by: Houko Kuwashima (JP), Kim Mai Guest (EN)"

A girl on Snake's Mission Control, she is a teenage prodigy and tech wiz who developed the Soliton Radar and the Codec. She frequently quotes proverbs to lift Snake's spirits up. She later becomes a Naval officer in the fourth game. -
 * Action Survivor
 * The Captain: In the fourth game.
 * Chinese Girl: Though she may or may not have an accent depending on which dub you're playing.
 * Gadgeteer Genius
 * Mission Control
 * Not Even Bothering With the Accent: Inverted. Although she does have a legitimate, if not slightly exaggerated Chinese accent, it also goes into odds with the fact that she was actually born and raised in America.
 * Teen Genius: In the original MGS.

FOXHOUND
A special forces group formed by Big Boss following the downfall of the original FOX unit. Both Solid Snake and Gray Fox were members of this unit. After Big Boss's Face Heel Turn in the first Metal Gear, the unit's co-founder and Executive Officer Roy Campbell becomes the new Commanding Officer in Metal Gear 2. The most well-known incarnation of the team is featured in Metal Gear Solid, where FOXHOUND has turned renegade after Solid Snake and Campbell left the unit. This incarnation of the team is composed of Solid Snake's Evil Twin Liquid Snake, his Dragon Revolver Ocelot, Ax Crazy Psycho Mantis, Defrosting Ice Queen Sniper Wolf, Magical Native American Vulcan Raven, and Replicant Snatcher (but not actual Snatcher) Decoy Octopus. -
 * Animal Motifs
 * Blood Knight: Most of the FOXHOUND members, or at least Vulcan Raven and Liquid Snake, qualify as such.
 * Dysfunction Junction: Liquid's combination of Well Done Son Guyism and homicidal resentment towards his father, Wolf's tragic past and Stalker With a Crush tendencies towards people she intends to kill, Ocelot's torture fetish, Mantis' violent misanthropy... Raven comes across as the most stable of the lot (at least of the members who get in-game character development), and he's an unapologetic Blood Knight.
 * Equal Opportunity Evil: Consists of an old Russian gunslinger, an asexual Russian psychic, a university-educated Native Alaskan shaman/heavy weapons enthusiast, an indestructible British-American cloned super warrior, a female Kurdish sniper, and Decoy Octopus.
 * Five Bad Band: See the complete Video Game Five Bad index for the full breakdown.
 * Five Token Band: A British-American, a Russian-American, an Iraqi, a Russian, an Inuit Shaman, and a Caucasian who can make himself look like any ethnicity.

Liquid Snake
"Voiced by: Banjo Ginga (JP), Cam Clarke (EN)"

The leader of FOXHOUND and Shadow Moses Island, Liquid is the second of the "Sons of Big Boss" introduced. He has a major complex about Solid Snake, and was told for his entire life that he inherited Big Boss' recessive genes in order that Solid Snake could get the dominant ones,. Word of God says he isn't naturally blond. - "Vulcan Raven: You are a snake which was not created by Nature. You and the Boss... you are from another world... a world that I do not wish to know."
 * You Fail Biology Forever: Doesn't know very much about genetics.
 * Badass Normal: Although he may arguably fall under Badass Abnormal due to being a clone.
 * Badass Longcoat
 * Badass Long Hair
 * Big Bad: One of the series' most famous.
 * Blond Guys Are Evil: As stated above, he wasn't originally blond, but the blond hair resulted from being under the hot sun as a POW in Iraq.
 * Blood Knight: Happily accepts it, unlike his brother.
 * Cain and Abel: To Snake.
 * Calling the Old Man Out: He hates Big Boss because he thinks Big Boss knowingly made him the inferior one during the Les Enfants Terribles project, and he implies that one of the main reasons for wanting to continue Big Boss's dream of a world of conflict is so he would further tarnish Big Boss's reputation ("Now I'll finish the work that father began. I will surpass him...I will destroy him!")
 * Child Soldier: He was raised within the British Military, and assuming what the Official Missions Handbook stated about him is canon, he may have done some mercenary work as early as Age 13.
 * Disney Villain Death: Averted so hard. At one point when fighting Snake, he fights him on top of the ruined Metal Gear REX mech, a mech that is over ten meters and to which he claimed that the fall would kill even Solid Snake. Despite being knocked off the mech, he still manages to survive and drive a Jeep, chasing Snake.
 * Engineered Public Confession: Subverted in Nastasha Romanenko's novel. He (and presumably the other terrorists) actually knew all along that they had planted a radio bug on Snake and was recording everything he and his soldiers were stating, and his codec calls, but allowed for it to happen anyways.
 * Evil Brit: Liquid was given to the British government as an infant and was raised as a national.
 * Evil Counterpart: Although he was the definite villain in the game, it was also implied to be inverted, as Psycho Mantis remarked that Solid Snake was actually worse than Liquid in his dying speech.
 * Evil Twin: Though Psycho Mantis has implied that Solid Snake may actually be the true Evil Twin. Liquid is fighting for a cause, the restoration of Outer Heaven. Snake is fighting because he, on a subconcious level, needs war to feel alive. Although he later finds other reasons to keep on living.
 * He Who Must Not Be Named: According to Campbell, Liquid's real name was highly classified to the extent that not even someone within the highest ranks of the military (such as himself) are allowed to know it.
 * Humanoid Abomination: Strongly implied to be such by Vulcan Raven:


 * Implacable Man: It's insane what the guy can survive.
 * Improbable Piloting Skills: He was fully capable of piloting a Hind D in the middle of a blizzard as well as shooting down two F-16s arriving from the Galena Air Force Base, and also pilot it while operating the weapons operator seat.
 * Large Ham
 * Light Is Not Good / Dark Is Evil: Liquid referred to himself and Snake as "the brother of light" and "the brother of dark", although of whom he was specifically referring to in regards to the titles is never actually specified.
 * Master of Disguise: Strongly implied to be such, seeing how
 * Military Brat: Was the clone of Big Boss as well as raised within the British Military, as implied in Peace Walker.
 * My Hair Came Out Blond: According to Yoji Shinkawa, Liquid Snake was originally dark-haired, just like Solid Snake. However, it ended up bleached to blond as a consequence of his time as a Prisoner of War, because of the sun's intense rays within the Iraqi desert.
 * Nietzsche Wannabe: Liquid Snake figures that he might as well do what his genes tell him, since otherwise, he's nothing. Justified, in that there's little else he ever had other than war, being created for the purpose of it.
 * No Shirt Long Jacket
 * The Pawn
 * Psychopathic Manchild: Assuming Ocelot's  portrayal of Liquid is valid, Liquid seems to qualify under this trope.
 * Psycho Prototype: Although it is heavily implied that Liquid Snake was created first, and the superior genes were used from him to create Solid Snake,.
 * Rasputinian Death: He survived having his Hind D shot down by Solid Snake, being hit with multiple Stinger missiles, being caught directly within the explosion of Metal Gear REX, surviving a four story fall from Metal Gear REX, was hit with several bullets by a turreted machine gun onboard a Jeep, was caught within a Jeep crash, and he was still ticking up until he succumbed to FOXDIE. Even then, with the last one, he lasted longer against it in the remake, initially collapsing out of agony, but then attempting to grab Snake twice before staring him down and finally passing away, in what was about a few minutes. Only his father and Vamp surpassed him.
 * Self Made Orphan: Kind of. Although he never actually killed Big Boss, nor, Liquid Snake made it very clear in his Motive Rant that he certainly would have murdered Big Boss himself had Solid Snake not done the deed himself, and in fact hated Snake partially because Snake "stole that chance."
 * Shadow Archetype
 * Social Darwinist: He believes that peoples' genes are all that matter in regards to fate or their future. Ironically, this actually has little to do with his actual plot (it was closer to a Warriors Heaven.)
 * Super Soldier
 * Walking Shirtless Scene
 * Well Done Son Guy
 * Xanatos Speed Chess: A large part of his Evil Plot was actually improvised by Psycho Mantis, since acquiring the PAL code from Baker and Anderson failed due to the latter dying under a botched torture session courtesy of Ocelot before he could divulge it.

Revolver Ocelot/Major Ocelot/Liquid Ocelot
"Young Voice: Takumi Yamazaki (JP), Josh Keaton (EN)

Old Voice: Koji Totani (JP, MGS1-MGS2), Banjo Ginga (JP, MGS4), Patrick Zimmerman (EN)"

Ocelot is a riddle wrapped in a mystery inside an enigma, known for his distinctive style of shooting a Single Action Army pistol (which he loves to reload), love of cowboy movies, love of torture, and ridiculous hand gestures. He also apparently works for FOXHOUND, the Sons of Liberty, and the Patriots, but for all we know he actually has an entirely different agenda. He is a major fixture of the series, being the only character to appear in five of the six Play Station games released as of yet.

In Metal Gear Solid 3 we find out that Ocelot was originally an agent of the GRU. In MGS4, Ocelot is possessed by Liquid Snake and goes by the name Liquid Ocelot. -
 * Arc Words: "You're pretty good!"
 * Awesome Anachronistic Apparel: He loves old gunslinger imagery, and fancies himself one. His outfit at Shadow Moses reflects this.
 * Awesomeness By Analysis: He learned CQC this way.
 * Badass
 * Badass Grandpa
 * Badass Gay
 * Badass Longcoat
 * Badass Normal
 * Bizarre and Improbable Ballistics: Ocelot makes the bullets go where he wants.
 * Breakout Villain: Very few people who finished the first Metal Gear Solid when it came out expected him to be anything more than Solidus Snake's lackey in the sequel.
 * But Not Too Foreign: His father is Russian and his mom is American. Both are soldiers, and he was born
 * The Chessmaster: One of the most brilliant examples you'll ever find.
 * Chronic Backstabbing Disorder: Trope Namer by way of The Last Days of Foxhound.
 * Cold Blooded Torture: Ocelot considers torture like a sport.
 * Cool Old Guy
 * Determinator: In regards to his actions in MGS3, he is this trope incarnate.
 * The Dog Bites Back: He had backstabbing tendencies as early as Metal Gear Solid, but his technical first time at genuinely backstabbing someone (disobeying Volgin's command to gun down Naked Snake during the final battle) was closer to this trope given the abuse he had to endure under Volgin.
 * Double Agent
 * Double Reverse Quadruple Agent: Provides the page quote. Over the course of the series he's worked for CIA, NSA, KGB, GRU, Colonel Volgin, FOXHOUND, rogue FOXHOUND, Colonel Gurlukuvich, Solidus Snake and the Patriots while not really working for any of them. In Metal Gear Solid 4,
 * The Dragon: To Liquid, Solidus, and Volgin (well, in spirit with the last one) respectively in the first three games.
 * He himself receives his own dragon in Metal Gear Solid 4 Guns of the Patriots with Vamp.
 * Dragon Ascendant: He's the Big Bad in the fourth game.
 * Enigmatic Minion
 * Even Evil Has Standards: He tells Naked Snake that he doesn't like killing his Russian comrades during the Virtuous Mission, and pleads with Volgin not to nuke Rassvet.
 * Fake Defector: Chronic Backstabbing Disorder aside, he,.
 * Good Looking Privates: In MGS3
 * The Gunfighter Wannabe: Throughout MGS3, he always tries a little bit too hard to impress people with tricks like spinning and juggling revolvers, and usually gets slapped down for it.
 * Gun Twirling
 * Improbable Aiming Skills: Six men with M60A rifles, one Ocelot with a Colt Single action. Think Ocelot should have tied one hand behind his back to make it fairer?
 * In Love With Your Carnage: Ocelot's pseudo-romantic admiration for Big Boss when he hears about Big Boss managing to kill people so easily (and his firsthand experience watching Big Boss neutralize the Ocelot Unit).
 * I Was Quite a Looker
 * Large Ham
 * Meaningful Titles: Ocelot uses Revolver, Major or Liquid before his Code Name.
 * "Major" isn't actually part of his codename, so much as its actually his rank.
 * Military Brat
 * Multiple Choice Past: Naomi mentioned that, according to his official case file, after the fall of the Soviet Union, he briefly worked as a member of the Russian Tax Police, OMOR, and the successor unit to the KGB, but left due to not liking the rigid rules. However, the Metal Gear Solid 4 database indicates that the case file was actually falsified to cover up his alliegance to the Patriots.
 * Also, in Metal Gear Solid 3, EVA explains in a radio conversation that she was told by Volgin that Volgin apparently raised Ocelot within GRU ever since the Philosophers kidnapped him during the Battle of Normandy after his birth. However, seeing how his codename was ADAM, and thus worked with the NSA in the past before "defecting" to the Soviet Union, and was also implied to be an agent of the CIA as well, its unlikely that Volgin's account is true at all, unless Volgin meant it figuratively.
 * No Celebrities Were Harmed: Based on Spaghetti Western actor Lee Van Cleef.
 * Noble Demon: In Snake Eater.
 * Otaku: Of spaghetti westerns.
 * Revolvers Are Just Better
 * Significant Birth Date: He was born during the Invasion of Normandy.
 * Single Target Sexuality: To Big Boss.
 * Stalker With a Crush: To Naked Snake/Big Boss.
 * Start of Darkness: Word of God states that Big Boss's enduring Volgin's torture is the reason why Ocelot became a torture fanatic, since beforehand, he held distaste for torture.
 * Take That Kiss:
 * Trigger Happy: "There's nothing like the feeling of slamming a long, silver bullet into a well greased chamber", indeed.
 * Torture Technician
 * Waistcoat of Style
 * Worthy Opponent: Constantly seeks a warrior as great as Big Boss to test his skills.
 * Young Gun: In Metal Gear Solid 3.
 * Zen Survivor
 * Waistcoat of Style
 * Worthy Opponent: Constantly seeks a warrior as great as Big Boss to test his skills.
 * Young Gun: In Metal Gear Solid 3.
 * Zen Survivor

Psycho Mantis
"Voiced By: Kazuyuki Sogabe (JP), Doug Stone (EN)"

FOXHOUND's psychic member, Psycho Mantis was driven insane when he went to deep into a psychopath's mind. Famous for reading the player's memory card and commenting on the games saved on it.


 * Asexuality: Psycho Mantis has a particular distaste for the biologically universal "need for breed."
 * Ax Crazy: Of all the members of Liquid's FOXHOUND unit, Mantis was shown to be the most insane and depraved.
 * Badass Longcoat
 * The Coats Are Off
 * Compelling Voice: It is implied that this is how Psycho Mantis applies his psychic abilities to place people under mind control (as his theme "Mantis' Hymn" often plays in the background of Meryl being brainwashed by Mantis, with Naomi also referring to it as his "mind control music").
 * Crucified Hero Shot: Inverted. Some official artworks as well as a certain attack of his have him in a pose similar to that of Jesus's crucifixion, and he's a villain.
 * Facial Horror: His usually hidden facial features are horribly disfigured and scarred as a result of being caught in a fire he started that burned his village to the ground.
 * For the Evulz: He reveals that he joined Liquid's little coup just to kill as many people as possible.
 * Good Scars Evil Scars: Has a huge scar running around his cranium and across the top of it, as well as a jagged Glasgow Grin.
 * Laughing Mad: Most times, his laughter reeks of this.
 * Lean and Mean
 * Leitmotif: Mantis' Hymn
 * Meaningful Name: The "Psycho" part of his codename has two meanings: One is in reference to his psychic abilities. The other is also short for "Psychopath" or "Psychotic", referring to Mantis' evident insanity.
 * A Mind Is a Terrible Thing To Read: One of Psycho Mantis' many problems.
 * No Fourth Wall: Probably the most obvious Fourth Wall Observer on the team, if not in the franchise.
 * Psychic Static: He wears the gasmask to keep it out.
 * Vader Breath: Naturally, he's wearing a gasmask, so the trope would apply.
 * Virtual Ghost: He is able to posses Screaming Mantis's armor after her defeat, and show off the fact that he knows jack about the PS 3's controller or save system.
 * Where I Was Born and Razed
 * Woobie Destroyer of Worlds: He saw little point in the "selfish desire of passing their genes on." The (questionably canon) Official Missions Handbook seems to heighten his stance, where it claims that he actually wants to end up dying because a parasite (a byproduct of those with genuine psychic powers) was making him do bad things despite his best efforts to control it, because when he is dying, it will be gone, and then he'll at least briefly experience a peace in mind.

Sniper Wolf
"Voiced By: Naoko Nakamura (JP), Tasia Valenza (EN)"

FOXHOUND's sniper. Normally a cold woman, she nonetheless was kind to the Shadow Moses' dogs and Hal, resulting in Hal's infatuation.


 * Absolute Cleavage
 * Cold Sniper
 * Dark Action Girl
 * Femme Fatale
 * In Love With the Mark: A rather twisted version, as Sniper Wolf becomes so obsessed with her targets that they are literally all she thinks about, to the point where she's said to fall in love with them... right before she puts a bullet through them anyway.
 * Laser Sight: Uses one.
 * Loves the Sound of Screaming: Kind of. She explains during her death speech that her lullabies were gunfire, sirens, and screaming; although the context it was given since she was actually born and raised during a time where her people, the Kurds, were being exterminated in Iraq, indicates that she was most likely meaning this literally.
 * Pet the Dog: Literally. And then there was the matter with
 * Woobie Destroyer of Worlds
 * You Gotta Have Blue Hair: Sniper Wolf's hair is a very pale shade of green.
 * You Gotta Have Blue Hair: Sniper Wolf's hair is a very pale shade of green.

Vulcan Raven
"Voiced By: Yukitoshi Hori (JP), Peter Lurie (EN)"

FOXHOUND's shaman. He first fights Solid Snake in a tank, then in cold storage with a minigun.


 * Adaptation Expansion: His character is heavily expanded on in the MGS comic, him being the one who informs Liquid of the deaths of Mantis and Wolf, and giving away the secret of FOXDIE, along with some scope of Liquid's plot during his confrontation against Snake, as opposed to his simple hint in the game.
 * Ammunition Backpack: Vulcan Raven wears a massive ammo tank for his minigun on his back.
 * BFG: His eponymous 20mm M61-A1 Vulcan. In the GC version, it's said he he ripped it off one of the F-16's Liquid shot down.
 * Charles Atlas Superpower: Vulcan Raven's main power is "being really, really big." This apparently allows him to use a ~600 pound-plus-ammo M61 Vulcan cannon.
 * It is implied in the game that Vulcan, being a shaman, has mystical powers as well as physical strength.
 * Gatling Good
 * Genius Bruiser: He's a giant who is more than capable of lifting and using a M 63 A 1 Vulcan cannon, yet was also educated at the University of Alaska, and shown to be somewhat of a strategist.
 * Made of Iron: He carries a Vulcan cannon, and ammo, shirtless. In the Alaskan permafrost.
 * Ravens and Crows
 * Tank Goodness: Vulcan Raven uses a tank during his first boss fight.
 * Walking Shirtless Scene

Decoy Octopus
FOXHOUND's impersonation expert. Solid Snake and the player never actually see what he looks like ingame. Instead Snake sees him when he is impersonating, who dies shortly after.


 * Badass Longcoat
 * The Blank
 * Lost in Character
 * Master of Disguise
 * Sacrificial Lamb
 * The Unfought
 * We Hardly Knew Ye

Meryl Silverburgh
"Voiced by: Kyoko Terase (JP), Debi Mae West (EN)"

The niece of Roy Campbell (later revealed to be his daughter), Meryl always dreamt of being in the military and living up to her heroes in FOXHOUND, but proves to be less than competent.

She later makes a comeback in MGS4, a lot more competent and tougher. -
 * Action Girl
 * Amazonian Beauty: Meryl is a lot sturdier looking by MGS4, compared to her appearance in Metal Gear Solid.
 * Cry Cute: In the ending of Act 1, after Ocelot's attempt at shutting down/hijacking the SOP system failed due to his using the wrong DNA (It Makes Sense in Context), Meryl is seen breaking down into tears due to her supressed emotions being unexpectedly released from the lockdown, strongly suggesting that, although she is certainly not a rookie anymore, she certainly hasn't gotten over her sorrow and reluctance to fire a weapon at living targets.
 * Debi Mae West: The role that made her famous.
 * Daddys Girl: Averted, her legal father died while she was very young, and she never actually knew that her birthfather was actually her uncle until after the events of Metal Gear Solid. Even after that, Meryl ends up having an estranged, non-talking relationship with her father both because he married a brunette woman who was young enough to be his daughter by the time of Metal Gear Solid 4 (not knowing that ) and from the fact that she was conceived by her uncle in an extra-marital affair with her mom that she learned from Roy Campbell. It wasn't until the ending where Meryl   that she and Campbell even start having a decent conversation.
 * Faux Action Girl: At least in the first game, though at least they admit it.
 * Heroes Want Redheads: Subverted: Meryl and Snake break up shortly after Shadow Moses.
 * Heroic Bastard: Meryl Silverburgh was conceived in an extramarital affair between her uncle, Roy Campbell, and her mother. It's also hinted that this is one of the reasons for her sore relations with her father in MGS4.
 * Hot Amazon: Her action girl status certainly seems to be a plus for Johnny.
 * Meryl Debuted In Metal Gear Solid: Not that you'd know it if you weren't Japanese.
 * Military Brat
 * Ms. Fanservice: In MGS. In addition to her being rather cute, a lot of emphasis is put on her rump (which actually becomes a plot point in the game when you have to identify her distinct hip-shaking walk when she's in disguise) and she even gets a couple scenes in her underwear.
 * Plucky Girl
 * Prison Rape: Implied at the end of Solid.
 * Took a Level In Badass
 * Tsundere
 * Victoria's Secret Compartment

Dr. Hal "Otacon" Emmerich
"Voiced by: Hideyuki Tanaka (JP), Christopher Randolf (EN)"

An Anime fanboy (so much so that his codename is based off an anime convention) Otacon is the designer of Metal Gear Rex, though he had no idea it was going to be used to launch nukes. After learning the truth, he vows to help Snake stop Metal Gear at all costs, and really becomes an Ascended Fanboy. -
 * Actor Allusion: Not in the series itself, but in Super Smash Bros Brawl, if using the Codec when fighting Captain Falcon at Shadow Moses, Otacon and Snake will reveal that they are both fans of the character. In the Japanese version, Otacon and Captain Falcon are both voiced by Hideyuki Tanaka.
 * Adorkable
 * Ambiguously Jewish: He has the last name of Emmerich, and his personality fits this Nice Jewish Boy / Jewish and Nerdy stereotypes.
 * Ascended Fanboy
 * Badass Labcoat
 * Cartwright Curse: This man is not lucky in love. He accumulates Tear Jerkers the way Snake collects CMoAs.
 * Cute Glasses Boy
 * The Heart
 * Hollywood Nerd: An interesting case of this: in the original game, he looked very much a nerd with messy hair and a weak deposition. In Sons of Liberty, he was designed a bit tougher, and his Character Development showed through. In Guns of the Patriots, Otacon becomes a full-out Hot Scientist who.
 * Heterosexual Life Partners: With Snake.
 * Ink Suit Actor: Kind of: He wasn't actually portrayed by series creator Hideo Kojima, but his overall design as well as certain mannerisms of Otacon in Metal Gear Solid 2 were based directly on him, if the Director's Commentary was anything to go by.
 * The Lancer/The Smart Guy: Doubles as both to Snake.
 * Likes Older Women: This is not something he would be proud of as it is a very tragic experience for him.
 * Lovable Nerd: And an effective foil against Snake's gruff hyper competence.
 * Mission Control
 * My God What Have I Done: The reason he joined Snake. See Not What I Signed On For below.
 * Nerds Are Sexy: Especially in the fourth game.
 * Nice Guy
 * Not What I Signed On For: He helped develop REX thinking it was a defense weapon, and out of a desire to make an actual mecha from animes. The guys who hired him conveniently left out the fact that the weapon he developed was actually a WMD.
 * Non Action Guy
 * Otaku: It's the reason he has the nickname/codename "Otacon."
 * Occidental Otaku
 * Say My Name: Snake? Snake?! SNAAAAAKKKKEEEE!!!!
 * Tender Tears: In a world filled with warriors, he is the only character in the franchise to shed these.

Johnny "Akiba" Sasaki
"Voiced by: Naoki Imamura (JP, 1st voice), Jun Fukuyama (JP, 2nd voice), Dean Scofield (EN, 1st voice), Beng Spies (EN, 2nd voice)"

Johnny first appeara in Metal Gear Solid as a guard with stomach problems whom Meryl strips and uses his clothes for her escape. His grandfather also served as a guard during the Cold War.

In Guns of the Patriots, he becomes a member of Meryl's Rat Patrol 01. -
 * Afraid of Needles:
 * : Once he takes off his balaclava and sunglasses.
 * But Not Too Foreign: His surname is Sasaki, but he is American-Russian and his features are clearly Caucasian.
 * Butt Monkey
 * Crouching Moron Hidden Badass
 * The Fool
 * Generation Xerox: Naked Snakes meet a guard who is Johnny's grandpa during MGS3. He is also named Johnny and shares the same intestinal problems and incompetence at his job.
 * The Gump: Johnny Sasaki's gimmick. By sheer coincidence, he manages to get involved in all of Snake's missions . His grandfather (also named Johnny) even met Big Boss during Operation Snake Eater.
 * Ill Boy: His perpetual diarrhea.
 * Ineffectual Sympathetic Villain
 * It Runs in The Family: All of the male first born in his family are named Johnny. Also, his grandfather is a prison guard like him.
 * Mask Power:
 * Military Brat
 * Naked People Are Funny
 * Notice This: The "J" on his balaclava is ridiculously out of place among legions of Faceless Goons.
 * Running To The Toilet Gag: His stomach problems
 * Military Brat
 * Naked People Are Funny
 * Notice This: The "J" on his balaclava is ridiculously out of place among legions of Faceless Goons.
 * Running To The Toilet Gag: His stomach problems
 * Running To The Toilet Gag: His stomach problems

Kenneth Baker
"Voiced By: Yuzuru Fujimoto (JP), Allan Lurie (EN)"

Former president of Arms Tech, the developer of Metal Gear REX. Solid Snake tries to rescue Baker after he is taken hostage in Shadow Moses, but Baker is killed by the FOXDIE virus before he can divulge any information about REX. -
 * Asshole Victim: Probably: The ability to have the stealth nuke on a railgun on REX to basically break retaliation theory is strongly implied to have been Baker's idea, and if the alluded to rumors of Boorda's true cause of death and the timing of the death and REX's development is anything to go by, he may have also had Boorda killed specifically because he wasn't able to get into the pentagon's black budget before Boorda.
 * Corrupt Corporate Executive
 * Sacrificial Lamb
 * The Stool Pigeon: Lacerated Larry Type: He divulged his half of the PAL code from having his arm broken by Ocelot, as he wasn't trained in physical interrogation.
 * We Hardly Knew Ye
 * Well Intentioned Extremist: He developed REX as a means to keep his company from going under as a result of SDI and his loss of the Generation X fighter plane to another stealth manufacturing company.
 * You Have Outlived Your Usefulness:

Next-Generation Special Forces
Also known as the Genome soldiers, they are soldiers enhanced genetically that rebelled and joined up with FOXHOUND. -
 * Genius Bruiser/Informed Ability: According to Naomi and Campbell, the Genome Soldiers, in addition to being skilled warriors, also have an IQ of 180. However, its hard to believe that they possess such intelligence when they end up missing Snake a few times.
 * Super Soldier: They were genetically enhanced with Big Boss's soldier genes.
 * Flawed Prototype: Every single one of the soldiers ended up undergoing an illness thanks to their having asymmetry theory. That's also not going into the Gulf War, where the Gulf War Syndrome and the Gulf War Babies that resulted in it were apparently side-effects of the procedure.
 * The Guards Must Be Crazy: Despite being intelligent soldiers, they apparently fail in spotting Snake even when he's only a few yards away from their line of vision. Probably justified regarding the outdoor soldiers, at least, since there was a blizzard at the time of the mission, which would cause a poor amount of visibility on their end. That's also not getting into the implication that
