"I never knew who my parents were or even what they looked like. I guess I got into genetics because I wanted to figure out why I'm the way I am."
A geneticist with a past even she's not completely sure of, Naomi was chosen to support Solid Snake during the Shadow Moses Incident to provide feedback on the Genome Soldiers. She had her own agendas, which included injecting Snake with the biological weapon FOXDIE to kill the FOXHOUND members, which would then kill Snake himself later. It turns out she did it because she was Gray Fox's adopted sister and she wanted revenge (although Liquid also mentions that the Pentagon ordering her to do so had something to do with it).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.
Action Dress Rip: Does it in Metal Gear Solid 4 when Snake, Drebin and she are being chased by Gekkos.
Ambiguously Brown: Lampshaded in Metal Gear Solid. She claims she became interested in genetics because she grew up knowing nothing about her own ancestry. This seems to have been forgotten by Metal Gear Solid 4, however.
Driven to Suicide: After explaining her actions to Snake and Otacon, she injects herself with what is essentially the kill switch for her nanomachines, allowing the cancer she has to kill her.
Ill Girl: She is revealed to have cancer in the fourth game. The only reason she's alive is because of specialized Nanomachines keeping it in check.
Intergenerational Friendship: With Sunny in Metal Gear Solid 4. She helps Sunny grow out of her shell, and finally learn to cook eggs right.
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.note which was originally a British colony before they declared independence during the Cold War.
Ironic Hell: Her tampering with the FOXDIE virus injected into Snake to have a wildcard activation to which even she won't know when it will activate, in revenge for Snake indirectly subjugating her brother, Gray Fox, through the Cyborg Ninja project / gene therapy project, ironically saves Snake from the intended fate of being killed by FOXDIE at the end of the mission. The Patriots also took note of this, as they had her imprisoned for doing that.
Just Following Orders / Not in This for Your Revolution: The other reason for injecting Snake with FOXDIE was because the Pentagon ordered her to, as they wanted a way to both get rid of the Sons of Big Boss, and at the same time retrieve REX and the Genome bodies without risk of them being damaged. Of course, her listing Snake as one of the targets of the virus, or at the very least modifying the virus to activate as a wildcard value in Snake's case, was certainly not done under their orders or even the Patriots' orders.
Known Only by Their Nickname: It is strongly implied that she is not actually named "Naomi Hunter" (Miller/Liquid mentioned that she stole the identity papers of the "real Naomi Hunter" at one point). Likewise, even she doesn't know her real name.
My God, What Have I Done?: A subtle version; she injects Snake with FOXDIE and modifies it so it'll kill him as well, but later has second thoughts after she realizes that Snake was far from the savage killer she thought of him as, especially after she discovers that Snake still considered Gray Fox a friend.
"Snake, remember what De Gaulle said: 'The graveyards are full of indispensable men.'"
A girl on Snake's Mission Control, she is a teenage prodigy and tech wiz who developed the Soliton Radar and Codec. She frequently quotes proverbs to lift Snake's spirits up. She later becomes a Naval officer in the fourth game.
Chinese Girl: Though she may or may not have an accent depending on which game you're playing. The English versions of Metal Gear Solid and Metal Gear Solid 2 feature the lisping and problematic relationship with the letter "r." She speaks normally in the other sequels.
Gadgeteer Genius / Teen Genius: In the original Metal Gear Solid. However, the Codec conversations in Metal Gear Solid 2 imply she's been pirating technology from the Pentagon. Snake gruffly warns Mei Ling to cut it out before she gets caught.
Not Even Bothering with the Accent: Although she does have a legitimate, if not slightly exaggerated Chinese accent, it's at odds with the fact that she was actually born and raised in America. Like Naomi, Mei Ling drops the accent altogether in The Twin Snakes; this became canon in Metal Gear Solid 4.
Ukrainian weapons expert, hired by Campbell and Ames to assist Snake via the Codec. Later on she recounts the Shadow Moses incident in a tell-all book entitled In the Darkness of Shadow Moses: The Unofficial Truth (which can be read in Metal Gear Solid 2).
Hypocritical Humor: If Snake calls Nastasha while smoking, she will warn you about the health risks of smoking. All while she has a cigarette in her mouth.
Back for the Finale: Rather surprisingly averted: Out of all the extant characters in the Metal Gear Solid games, she's one of the very few that doesn't make a reappearance in Metal Gear Solid 4, the Grand Finale of the series.
Screw This, I'm Outta Here!: After the events of the Shadow Moses Incident, she went into hiding in fear that everything she learned, and her own involvement assisting Snake, might potentially put her life in danger.
Soapbox Sadie: She often rants about the dangers of nuclear weapons.
What Happened to the Mouse?: After MGS1, we barely hear from her again. All we know is that she wrote a book on the Shadow Moses incident, and Richard Ames is her husband.
Blood Knight: Most of the FOXHOUND members, or at least Vulcan Raven and Liquid Snake, qualify as such.
Dangerously Genre Savvy: Liquid Snake and the rest of the FOXHOUND members heavily anticipated that Snake would be deployed to Shadow Moses Island, and even anticipated the likelihood that he'd be secretly monitored by the Patriots, so they continued acting as though they actually had all codes even when Snake was unconscious or offscreen until Snake unwittingly activated REX for them. In fact, even the one time Liquid potentially messed up in regards to his identity (citing things that "Miller" shouldn't know from being holed up in Alaska), it was clear that even if they managed to find out that Miller was actually dead by that time, it would be far too late to stop his plans.
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, and 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-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 ethnicitynote Although he is identified as being Mexican in some sources, although it's implied that a lot of these guys had American citizenship to join.
"With all the liars and hypocrites running the world, war isn't what it used to be. We're losing our place in a world that no longer needs us. A world that now spurns our very existence!"
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 his inheritance of Big Boss' recessive genes made him the inferior clone, when in fact the reverse was true. A tyke bearing a strong likeness to Liquid makes an appearance in The Phantom Pain's trailer, so it is possible that Solid might make his debut as well. Word of God says he isn't naturally blond.
Ace Pilot: Manages to shoot down two F-16s with a Hind D.
Though at least some of this might be because he just needs to explain it better.
Also in Metal Gear Solid 2, it is revealed by Emma Emmerich that the Patriots have spread much false information throughout society, including on biology. Considering that Liquid's childhood was highly influenced by the Patriots, he probably was outright lied to about biology.
Badass Normal: Although he may argue this due to him being a clone.
Cain and Abel: To Snake. He seems to be trying to invoke the trope; he is constantly playing up their fraternal link, and his hatred of Snake is unreasonably deep and personal, considering Snake wasn't even aware of his existence until the events of MGS.
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!")
The Chessmaster: Of the Shadow Moses Incident, although later games would reveal him as The Pawn in the bigger scheme of things.
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.
The Determinator: The only Metal Gear villain Snake was unable to defeat, despite several temporary wins. He just will not die. It takes a biological WMD to kill him.
Disney Villain Death: Averted. 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 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.
Even Evil Has Standards: In codec calls to Miller/Liquid during the first boss battle, he mentions that Ocelot is too warped even for him.
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 antagonist in the game, it was also implied to be inverted, as Psycho Mantis remarked that Snake was actually worse than Liquid in his dying speech.
Evil Twin: Though Mantis implied that 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.
Evil Brunette Twin: Inverted. He is the evil twin, but he is blond, while his good twin has brown hair.
Great White Hunter: Liquid, an Englishman through and though, enjoys fox hunting as a sport. When assigned to the Middle East (where no foxes or hounds were forthcoming), he substituted it with hunting jackals and using royal harriers.
The Heavy: The last quarter of Metal Gear Solid is one long battle between Snake and Liquid. Even before that, he was in contact with Snake via the Codec for the entire game disguised as Master Miller.
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.
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: His top ham moment is whenever he exclaims, "BROTHER!"
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 specified.
Master of Disguise: Strongly implied to be such, seeing how he effectively disguised himself as Master Miller after arranging for the latter's death.
Meaningful Name: The very definition of "liquid" is "an unstable substance that has no constant shape or structure". When you compare Liquid's personality to that of Solid Snake, his twin, this makes perfect sense. Compared to Snake (who has his flaws, but stays loyal to his friends and has a constant set of values) Liquid is a dangerously unstable figure without any permanent ideals or goals beyond wreaking havoc on a world that wronged him and finding his place in a world of unending war.
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 was originally dark-haired, just like Snake. However, it ended up bleached to blond as a consequence of his time as a POW, because of the sun's intense rays within the Iraqi desert. Interestingly, Snake was originally going to be a natural blond, too; hence his lighter hair color in the briefing videos.
Nietzsche Wannabe: Liquid 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.
Not So Different: Liquid gave this spiel on top of Metal Gear REX, though Snake rejected the notion that he's just a born killer. However, Liquid's words have definitely stuck with him; one of the trophies in Metal Gear Solid 4 is acquired by gunning down 100 mooks; Liquid's mocking laughter and echo, "You enjoy all the killing!", causes a guilt-ridden Snake to vomit.
Psychopathic Manchild: Assuming Ocelot's fake possession portrayal of Liquid is valid, Liquid seems to qualify under this.
Psycho Prototype: Although it is heavily implied that Liquid was created first, and the superior genes were used from him to create Snake, The Stinger subverts this by revealing that he had the superior genes all along.
Rasputinian Death: He survived having his Hind D shot down by 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 was Big Boss actually dead, anyway, Liquid made it very clear in his Motive Rant that he certainly would have murdered Big Boss himself had Snake not done the deed himself, and in fact hated Snake partially because Snake "stole that chance."
Separated at Birth: With Solid Snake. They were born in Carlsbad, New Mexico but Snake spent his childhood in Oregon while Liquid was moved to England shortly after their birth. They had similar upbringings though, both being raised in isolation and receiving extensive education and military trainng.
Sibling Seniority Squabble: Averted. When he first meets his twin brother face-to-face, he says that he's not sure whether to call him "big brother" or "little brother", before deciding that it doesn't matter anyway.
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 Warrior Heaven).
Woobie, Destroyer of Worlds: The Metal Gear Solid 4 novelization, along with the Official Missions Handbook expands a lot on Liquid's background: He basically was sent into Iraq before the advent of the Iraq War, for the sake of Britain as a sleeper agent to organize various insurgencies in Iraq, and also located several things thanks to connections he made with insurgents against Saddam Hussein's government. However, just as he was to act on destroying the SCUD missile launchers (at least 4 were destroyed by this time), he ended up captured by Iraqi paratroopers belonging to al-Amn al-'Amm secret police, with the strong implication that the SIS sold him out for a more valuable source of information from within Hussein's inner circle, leaving him to be heavily tortured and brainwashed, which evidentially led to his Humans Are Bastards viewpoint in the first game. Just when he was getting his act together by the time he started leading FOXHOUND, Ocelot had to reveal to him that he was a LET clone, causing him to sink real low in anger and self-loathing and transform him into the character we see from Metal Gear Solid onward. Honestly, who can blame him for the stuff he pulled after knowing that?
Xanatos Speed Chess: A large part of his Evil Plan was actually improvised by Psycho Mantis, since acquiring the PAL code from Baker and Anderson failed due to the latter dying under a supposedly botched torture session courtesy of Ocelot before he could divulge it.
"We're going to play a game, Snake. And we'll find out what kind of man you really are."
"The world today has become too soft. We're living in an age where true feelings are suppressed. So we're going to shake things up a bit."
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. Originally an irredeemable goon, he becomes more sympathetic through his rapport with Big Boss in the prequels.He is a major fixture of the series, being the only character to appear in all the numbered Metal Gear Solid games. At Shadow Moses, he serves as Liquid's right-hand man, and seems to do the same at the Big Shell. In Metal Gear Solid 3, a young Ocelot appears as Volgin's minion. In Metal Gear Solid 4, Ocelot is a Dragon Ascendant, going now by the name Liquid Ocelot thanks to his replacement arm, stolen from Liquid Snake, taking over his mind. Finally, he appears in Metal Gear Solid V, where he rescues Big Boss on horseback and joins his "Diamond Dogs" mercenary unit.
He and his pack of Elite Mooks, the Ocelot Unit, wear the red/maroon berets of the Spetznaz GRU, the black combat uniform of the Naval Infantry, the black telnyashka (striped shirt) of the Soviet Navy, and the knee-high black leather officer's boots (opposed to the trooper's boots used by KGB and GRU). It seems Major Ocelot has a lot of leeway with putting together his unit.
Badass: He's a spymaster who's been taking on professional soldiers since the 1960s.
Badass Grandpa: Is in his 60s over the Solid games, and still manages to take on a professional killer like Solid Snake.
Bizarre and Improbable Ballistics: The "Master of Ricochet." Ocelot can somehow bounce his bullets off walls and other objects to go exactly where he wants. The trick to beating him is to not reveal your location; if he sees you duck and cover, it's all over.
Book Ends: Ocelot is the first and last boss of the "Solid Snake Saga".
Breakout Villain: Very few people who finished the original Metal Gear Solid when it came out expected him to be anything more than Solidus's lackey in the sequel.
Cats Are Mean: This is more evident in Metal Gear Solid 3, where Young Ocelot imitates an ocelot's growl to summon his men. About the nicest thing you can say for Ocelot is that he believes in a fair fight, as jungle cats "prefer to hunt alone." Needless to say, this stands in contrast to Big Boss/Snake's cheap tactics and fondness for dogs.
Cold-Blooded Torture: Ocelot thinks of torture like a sport (though he kinda sucks at it since people under his "care" end up dying without producing anything useful, was probably a learned trait from Volgin).
The Determinator: In Metal Gear Solid 3. No matter how many times Snake beats/humiliates him, he gets back up and comes back again, pursuing Snake.
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 given the abuse he had to endure under Volgin. Even if his serving Volgin was technically a ruse to begin with.
Double Agent: In Metal Gear Solid, he's not actually working for Liquid, but the U.S. Government. It wasn't until Metal Gear Solid 2 that he became a...
Double Reverse Quadruple Agent: Over the course of the series, he's worked for the NSA, CIA, KGB, GRU, Colonel Volgin, FOXHOUND, rogue FOXHOUND, Colonel Gurlukovich, Solidus Snake and the Patriots while not really working for any of them. Metal Gear Solid 4 reveals his true allegiance was to Big Boss ever since Metal Gear Solid 3.
The Dragon: Serves as the right hand man to Liquid, Solidus and Volgin respectively over the first three games.
Dragon Ascendant: He's the Big Bad in the fourth game, with Vamp as his Dragon. Everything that we see him do from the original Metal Gear Solid onwards is his attempts to destroy the Patriots and fulfill Big Boss's wishes.
Dystopia Justifies the Means: He is said to have applauded Big Boss' vision of a strife-ridden world, likening it to his own favorite era: the Wild West. As stated in the original Metal Gear Solidnote The player has to survive the third torture round without submitting to learn it, was that he believes that, in a world filled with war, people at least could express their true emotions and personality, especially when the current age prevents them from doing so.
Foreshadowing: So much. In the original: why would a Russian dress as a cowboy, use an American gun, and name himself after an American cat? Because he's working for the American government, and his mother was one of America's greatest war heroes. In Sons of Liberty: why is he being possessed by a transplanted arm? Snake Eater gives the reason that his father was a medium, but it's revealed in Guns of the Patriots that it's part of a long and complex plan to save the world from The Patriots.
Good All Along: Well, "good" is a bit much, but he really just wanted to destroy the Patriots and save Big Boss from a Fate Worse than Death, despite the antagonistic means he used to get there.
The Gunfighter Wannabe: Throughout Metal Gear Solid 3, 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: It has practical applications too: Young Ocelot uses this skill to survive an onslaught of The Pain's hornets. That's right, he killed a bunch of hornets that were about to sting him to death by hitting them with his spinning guns.
Honor Before Reason: In MGS3, to the extent that he calls Big Boss out if he uses such means as tossing grenades or shooting down hornet's nests while fighting him.
I Fight for the Strongest Side: Big Boss and his progeny are the only people Ocelot truly respects. He is the only character in the series to interact with all four. Unlike most examples of the trope, he doesn't do this because he's afraid of them, but because he respects them and believes only they are worthy of his service.
I Love the Smell of X in the Morning: Pretty much everything associated with revolvers gets him aroused. He comments on the smell of cordite ("Y'know, that sulfury smell?") during his duel on Shadow Moses.
I Will Punish Your Friend for Your Failure: Ocelot continual zaps Snake will just enough electricity so as not to kill him, testing to see if he'll beg for mercy. If you do press the surrender button, Ocelot will discontinue the torture, then announce that he's about to go kill Meryl. He wants to break Snake's spirit, not kill him.
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.
I Was Quite a Looker: Was fairly attractive during his youth in Metal Gear Solid 3. To be fair, he doesn't really look too terrible in the present either.
Maybe Magic, Maybe Mundane: It is stated that Ocelot began his "Liquid Ocelot" ruse as far back as when he had Liquid's actual arm attached (ie. Metal Gear Solid 2's Tanker and Big Shell Incidents) but he replaces it for a synthetic arm in the intervening time between 2 and 4 because the initial transplant was unstable and affected his psyche. The implications of this and the apparent cause of instability are left vague, but given that The Sorrow, a medium is his father, it's more than possible that Liquid really was posessing Ocelot for a time.
Meaningful Titles: Ocelot uses Revolver, Major or Liquid before his codename. In the case of "Major", it is actually his rank.
Mega Manning: He learned Close Quarter Combat simply by observing Big Boss and other soldiers.
Money to Throw Away: An early hint that Ocelot isn't in this for your revolution, Princess. Though he acts excited about the payout during conversations with Liquid, Ocelot is just playing it up for Snake. During the torture sequence, he reacts with scorn to Snake's implication that he wants money. Ocelot's an ex-spy and mercenary: He doesn't need any more money.
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 allegiance 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.
Never Got to Say Goodbye: Like Naomi and EVA/Big Mama, he went through all sorts of shit to revive Big Boss, and died before he ever got to see him again.
Ocelot: He's good. Volgin: Fallen for him, have you?
He expressed an interest in both Sniper Wolf and Meryl in Metal Gear Solid, but soon jettisoned the Dirty Old Man part of his character makeup. In fact, he was outwardly repulsed by EVA's ridiculous perfume and breast implants.
Smug Super: While insufferably vain and flamboyant, his inflated ego is more than backed up by seemingly superhuman reflexes and marksmanship abilities which enable him to take down countless soldiers en masse with nothing but a Single Action Army revolver. He is also revealed to a highly skilled practicioner of CQC.
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.
Worthy Opponent: Constantly seeks a warrior as great as Big Boss to test his skills.
You Bastard: The "Otacon" outcome of the torture sequence. Basically, Ocelot crows that he's going to rape/torture/murder Meryl, and it's all your fault. "I hope you can still look at yourself in the mirror."
"I never agreed with the Boss's revolution. His dreams of world conquest do not interest me. I just wanted an excuse to kill as many people as I could."
FOXHOUND's psychic member, Psycho Mantis was driven insane when he went too deep into a psychopath's mind. Famous for reading the player's memory card and commenting on the games saved on it. A young Mantis is shown terrorizing Big Boss with hallucinations in Metal Gear Solid V's trailer.
Asexuality: 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.
Compelling Voice: It is implied that this is how 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.
Death Equals Redemption: It's subtle, but his last words are very effective at conveying how different Mantis might have turned out.
"This is the first time I've ever used my power to help someone. It's strange... it feels... kind of... nice."
Die As Myself: His mind-reading is involuntary; part of the reason he wears the mask is to keep other people's thoughts out. Thus, after Snake takes off his mask as he approaches death, he asks him to put it back on.
Facial Horror: His usually hidden facial features are horribly disfigured and scarred as a result of being caught in a fire he started when he burned his village to the ground. When Snake unmasks him upon his death, Meryl is completely grossed out.
Go Mad from the Revelation: Twice. The first as a boy, when he read his father's mind and found that he hated him, possibly enough to want to kill him, leading Mantis to psychically destroy his village. The second was during his stint in the FBI, when he went too deep into the mind of a serial killer, causing Mantis to adopt said killer's personality.
Hoist by His Own Petard: Snake's first person view is replaced by Mantis' line of sight during their battle. If you failed to pick up the thermal goggles, you can easily discern his position by using this.
House of Broken Mirrors: The office where Mantis is lurking has a smashed mirror, plus numerous marble busts with duct tape covering their faces (mirroring Mantis' own). In The Twin Snakes, he uses his mental powers to distort even the wall photos.
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.
The only mantis-like thing about him is his lean build, which makes him resemble said insect physically, if not mentally or otherwise.
On a subtler note, "Mantis" is derived from "Mantodea," the Greek and Latin word for "Prophet," which emphasizes his psychic abilities further still.
Mind over Matter: His projectiles aren't a big threat. The worst obstacles are the office decorations he flings at you: somersaulting chairs, marble statues buzzing around Mantis' body, and even flying deer antlers.
Vader Breath: Naturally, he's wearing a gas mask, so this would apply.
Virtual Ghost: He is able to possess Screaming Mantis's armor after her defeat, and show off the fact that he knows jack about the PlayStation 3's controller or save system.
Where I Was Born and Razed: For once, perhaps, this was (or at least is implied to have been) an accident; realizing his father hated him for his mother's death in childbirth must have caused a lot of trauma for the young Mantis, and he mentions waking up to a fire in progress. Exactly how it happened is never highlighted (presumably because Mantis doesn't know) but it's not unbelievable that his powers exploded in reaction to his father's malice and set the village alight...
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.
"I told you. I never quit the hunt. Now you're mine."
FOXHOUND's Kurd sniper, notable for her ability to stay locked onto a target as long as it takes until it comes time to pull the trigger. Normally a cold woman, she nonetheless was kind to the wolfdogs on Shadow Moses and her hostage Hal Emmerich, resulting in Hal's infatuation. Wolf is another disciple of Big Boss, who rescued her from the middle east as a young girl. The Kurdish connection looks to be explored in the upcoming Phantom Pain.
Abnormal Ammo: According to her Konami bio, she uses mercury bullets to poison her victims as well.
Click Hello: Following their initial shootout, Snake walks up to the as-of-yet unseen Wolf's sniper nest and immediately gets held up.
Cold Sniper: This lady won't move. Days, weeks, it doesn't matter.
Come Out, Come Out, Wherever You Are: Wolf's one of the very few Metal Gear opponents who manages to hijack the radio, the others being Fox (whose status as an opponent is debatable by the end of the game), Liquid (who was using Miller's alias and frequency), and the Patriots themselves.
Companion Cube: Wolf considers her PSG-1 to be a bodily organ, stopping just short of I Call It Vera. She requests to hold it to her chest as she dies, commenting, "Everyone's here now."
Femme Fatalons: Wolf seems to anticipate Snake eventually getting free from Ocelot's captivity, as she swipes at Snake's cheek to leave her "mark." This serves as notice, according to her, that she'll put a bullet in Snake more soon than late.
Friend to All Living Things: The wolfdogs are trained to recognize Sniper Wolf by scent. Wearing her handkerchief causes them to wag their tails happily, even around Snake.
Functional Addict: She's addicted to diazapam, the same pills Snake ingests to reduce hand tremors while aiming. Creepy. This is a side-effect of Wolf's refusal to switch shifts with a backup sniper. On the upside, her constant intake of tranquilizers seemed to suppress FOXDIE, if not outright neutralize it.
In Love with the Mark: A rather twisted version, as 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.
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 Otacon.
Reincarnation: Otacon seems to think Wolf is still haunting Shadow Moses. In Metal Gear Solid 4, Crying Wolf is killed in the same spot where Sniper Wolf died. A wolf scoops up her body and disappears into the woods; the game implies this is the spirit of Sniper Wolf.
Shout-Out: According to Kojima, the scene where Sniper Wolf riddles Meryl with rounds from a sniper rifle was based on Full Metal Jacket. Similarly, one of her lines ("Well I'm going to send you a love letter, my dear.") was a direct lift from Blue Velvet.
Straw Feminist: Wolf holds a few sexist views, claiming that women made better soldiers than men. She taunts Snake for being an example of men who "can never finish what [they] start," as well as boasting that two thirds of the world's greatest assassins are women.
"Yes. The raven on my head, it thirsts for his blood."
FOXHOUND's shaman. He first fights Solid Snake in a tank, then in cold storage with a gatling gun.
Actually Pretty Funny: Snake quips that the tank he used in their first fight "must have been a tight fit for a big boy like you." Rather than getting angry, Raven has a good laugh about it before shrugging it off.
Adaptation Expansion: His character is heavily expanded on in the Metal Gear Solid comic, with 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.
Charles Atlas Superpower: Raven's main power is "being really, really big." This apparently allows him to use a ~600 pound-plus-ammo M61 Vulcan cannon. And in The Twin Snakes, he casually grabs one of those big-ass metal storage crates and chucks it at Snake like it was a beanbag.
It is implied in the game that Raven, being a shaman, has mystical powers as well as physical strength.
Expy: of Machinegun Kid from the original Metal Gear, particularly in how their battles are handled.
Face Death with Dignity: Rather than be killed by Snake like Wolf, bleed out like Mantis or die as a result of FOXDIE like Octopus, Raven chooses to let himself be consumed by his flock of ravens, fitting his philosophy that rather than being simple scavangers, ravens simply return to the natural world that which is no longer needed. He claims his spirit will return to Mother Nature through this method.
Worthy Opponent: He regards Snake as such and tells him to rejoice for what he promises will be an awesome battle. He compares their standoff to an Alaskan Olympic event called the Ear-Pull, a test of spiritual and physical strength in which two opponents pull each other's ears while braving the Winter cold.
FOXHOUND's impersonation expert. Solid Snake never actually sees what he looks like in-game, though a brief flashback shows Raven pulling off his mask. Instead Snake sees him when he is impersonating Donald Anderson, and he dies shortly after.
Dead All Along: In a way. He does die onscreen and in the presence of Snake but by the time you even learn of the existence of the man, it's far too late to matter since he died way back there.
Lost in Character: Octopus originally worked in Hollywood as an actor and SFX artist. Afterwards, he was recruited by the CIA for his exceptional skills in mimicry.
Master of Disguise: When impersonating someone, he will even go so far as to substitute his blood for their own. However, this is likely due to the fact most of his high-value targets carry nanomachines. Using the DARPA Chief's blood, Octopus was able to appear on Snake's Soliton Radar.
Polyglot: Octopus was fluent in a dozen languages.
Red Right Hand: Octopus can't alter the size of his skull, but did elect to have his ears surgically removed. He also had his hairline, cheekbones, jaw, and nasal bones shaved down, to make disguising himself easier, and has a voice synthesizer implanted in his throat.
"I was a fan of FOXHOUND way back. When guys like you and my uncle were in it. None of that gene therapy like there is today. You guys were real heroes."
The niece of Roy Campbell (later revealed to actually 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 Metal Gear Solid 4 and is a lot more competent and tougher.
Amazonian Beauty: Meryl is a lot sturdier looking by Metal Gear Solid 4, compared to her appearance in Metal Gear Solid. When you see her in her wedding dress, her arms are very noticeable, especially when she arm wrestles one of her teammates.
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 suppressed 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.
Daddy's 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 (Rosemary) who was young enough to be his daughter by the time of Metal Gear Solid 4 (not knowing that the marriage was actually a sham to protect Rose and her son from the Patriots, as they won't use them as leverage for Raiden) 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 marries Johnny Sasaki/Akiba that she and Campbell even start having a decent conversation.
Faux Action Girl: A deconstruction of it in the first game. She badly wants to be an Action Girl, but she's completely inexperienced and in over her head, and has has her illusions destroyed when she learns that War Is Hell.
Heroic Bastard: Meryl 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 Metal Gear Solid 4.
Ms. Fanservice: In Metal Gear Solid. 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.
The Other Darrin: An interesting variation: In the English version of Snake Tales in Metal Gear Solid 2: Substance, she's "voiced" by Vanessa Marshall, because her "voice" was actually reused voice clips of Olga Gurlukovich. In the Japanese version, it makes more sense, as Olga and Meryl shared the same voice actress.
Took a Level in Jerkass: She's pretty hard on Snake in Metal Gear Solid 4. She deliberately and venomously calls him "Old Snake" just to put him down, and it appears that she has no sympathy to either him or Johnny. However, this is not the case. When Snake and Meryl first meet in the Middle East, she's concerned and sympathetic to his aging problem. And of course, when Johnny reveals that he has no nanomachines, she's clearly sorry that she treated him like crap.
"Three generations of Emmerich men. We must have the curse of nuclear weapons written into our DNA."
Computer engineer and part-time hacker (and full-time Woobie) whom Snake befriends in Alaska. Ashamed of his family's involvement in the Manhattan Project, he chose to pursue his boyhood passion for making robots, only to discover (to his horror) that REX had been outfitted for warheads without his knowledge. He promptly allied himself with Snake in hopes of abolishing Metal Gear. The duo have been presumed dead (several times) by the U.S. government, which freed them up to pursue more clandestine modes of warfare, including Anonymous-style activism and sabotage.An anime fanboy (so much so that his codename is based off an anime convention), Otacon could not be more unlike his partner. He serves as the 'brain' of the Solid Snake Trilogy.
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 of F-Zero's anime adaptation (Falcon Densetsu), Captain Falcon is voiced by Hideyuki Tanaka, who voices Otacon here.
Ambiguous Disorder: He's socially awkward, rather Literal-Minded (see the Chinese Proverbs in Metal Gear Solid 2), obsessive about his interests, and often doesn't seem to have much understanding of other people's motivations.
Chick Magnet: His stepmom and sister, Naomi, etc. In Metal Gear Rising: Revengeance, it is mentioned by Raiden and Sunny that he became more attractive, but he's still non-commital and won't settle down out of fear of hurting anyone else.
Ditzy Genius: Particularly in his first appearance. He's a brilliant engineer, but rather clueless about the realities of his situation and the people around him. He gets a bit savvier in later games, although he's still rather quirky.
Fire-Forged Friends: Their relationship began with Snake choking the ever-loving crap out of him. They end up saving each other's bacon a couple times, and have numerous off-screen adventures all over the world.
Generation Xerox: Has an almost identical personality to his father, his relationship with Snake mirrors his father's to Big Boss, and they both wound up unwittingly designing walking nuclear death tanks for a questionable force. Not to mention they both apparently have uncomfortably similar taste in women, considering Otacon sleeps with his stepmother.
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 Metal Gear Solid 2, he was designed a bit tougher, and his Character Development showed through. In Metal Gear Solid 4, Otacon becomes a full-out Hot Scientist who gets it on with Naomi.
Hikikomori: His shabby, unshaven appearance on Shadow Moses Island is likely a nod to the stereotypical shut-in lifestyle. In actuality, Otacon spends most of his waking hours in a basement laboratory.
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.
Lennon Specs: Otacon wears pice-nez specatacles in his first appearance. His glasses gradually become more rectangular in subsequent games.
Likes Older Women: This is not something he would be proud of as it is a very tragic experience for him. He was seduced by his stepmother and his father caught him in the act and committed suicide by drowning himself in the pool. Unfortunately, he accidentally dragged Emma along with him, causing her hydrophobia.
Line-of-Sight Name: As a civilian, he doesn't actually require a codename, but he insisted that Snake refer to him as Otacon. His passion for anime is reflected in the posters on the office walls.
Lovable Nerd: And an effective foil against Snake's gruff hyper competence.
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.
Playful Hacker: Otacon has a habit of sneaking code into REX that his employer specifically forbid him to. In addition to REX's weakpoint (a "character flaw" to give it personality), Otacon also implemented a program to make REX fight like a boxer, using its own body as a weapon. The suits didn't approve of risking Metal Gear's delicate sensors, but the program is still in there, as Snake discovers in Metal Gear Solid 4.
Johnny first appears 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 Metal Gear Solid 4, he becomes a member of Meryl's Rat Patrol Team 01. He loved Meryl ever since she stripped him in Shadow Moses, and ends up marrying her after admitting his love for her.
Ascended Extra: In the first three games he was a comedic relief character, until Metal Gear Solid 4, where he evolves into a Badass Normal and becomes Meryl's love interest.
Adorkable: In Metal Gear Solid 4, he's a pretty sweet and awkward guy off the battlefield. As a soldier, he emulates Meryl's lack of expertise from Metal Gear Solid. At least, until the mask comes off...
Afraid of Needles: The explanation Johnny gives when revealing why he doesn't have any nanomachines in his body.
Amazon Chaser: Meryl's action girl status certainly seems to be a plus for Johnny.
Been There, Shaped History: Johnny's gimmick. By sheer coincidence, he manages to get involved in all of Snake's missions. note He's a Genome Soldier in the first game, a Gurlukovich mercenary in the second, and a member of Rat Patrol Team 01 in the fourth. His grandfather (also named Johnny) even met Big Boss during Operation Snake Eater.
Bishōnen: Who knew he was one all along under that mask?
Bring My Brown Pants: If he doesn't actually shit his pants in his appearances, he comes pretty damn close to it.
But Not Too Foreign: His surname is Sasaki, but he is American-Russian and his features are clearly Caucasian.
Nice Guy: Despite his inability as a soldier at first, he's pretty upbeat and friendly when he's not being tormented by bowel problems. His abrasiveness towards Snake in the first game is understandable, being his prison guard and all.
"Maybe they're like us in the arms industry. Always looking forward to the next good war."
Former president of ArmsTech, 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 rail gun 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: Though he's no more corrupt than any of the other arms dealers bribing Congress. He's really just trying to save his company, which is in danger of going bankrupt.
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. He was the only one to divulge his code, as Anderson died before he could divulge the other half thanks to Ocelot.
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.
Commonly known as the Genome Soldiers, they are soldiers enhanced genetically that rebelled and joined up with FOXHOUND. They come in four main variants: arctic warfare, light infantry, NBC warfare and Heavily Armed Troops.
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.
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 they deliberately avoided spotting Snake in order to trick Snake into activating REX.
The Goomba: The Arctic Warfare variants are the first one to appear, but the Light Infantry soldiers are actually much more common and weaker.
Mascot Mook: The Arctic Warfare soldiers reappear more often in later games than the other enemy types in the original MGS, such as in the VR Missions expansion, Portable Ops Plus and in the Deja Vu mission in Ground Zeroes.
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.
