!!Characters that debuted in ''Metal Gear Solid 4: Guns of the Patriots'':


[[folder: Sunny Emmerich ]]
[[caption-width-right:300:''[-"I'm just hoping we can get to Jupiter while Hal's still alive."-]'' ]]
->Voiced By: Creator/KikukoInoue (JP), Christina Puccelli (EN)

->''"Killing the Patriots was not enough to end war. It didn't create this big, happy utopia. But you know what? Seeing Sunny doing so well... Makes me damn happy the Patriots are gone."''

The daughter of Olga Gurlukovich. Raiden rescued her from the Patriots and dropped her off with Otacon and Solid Snake, who raised her on-board their giant airplane headquarters. Sunny is a computer programming genius, but lacks social and cooking skills due to her sheltered upbringing. She returns in ''VideoGame/MetalGearRisingRevengeance'', now going by the last name of her foster father, Emmerich.
* ChildProdigy: Her brain was experimented upon by the Patriots as an infant and she was raised by Otacon, a brilliant robotics engineer and computer technician, making her an adept at computer programming even at the age of 7. By the time the events of ''Rising'' come around, she's working as an engineer, developing a Mach 23 aircraft before even reaching her teen years!
* FlowerInHerHair: During the Act 3 mission briefing, Naomi puts a blue rose in Sunny's hair to show her how pretty she can be. In ''Rising'', she wears a blue rose hair clip.
* HappilyAdopted: Sunny adores her adoptive fathers and isn't afraid to show it.
* [[HasTwoMommies Has Two Daddies]]: Was raised by Snake and "Uncle Hal", the latter of whom became her official legal guardian by the time of ''Rising''. An argument can be made for Raiden to act as her third dad, since he rescued her from the Patriots as a child.
* TheHeart: In ''Metal Gear Rising''. Could also apply in ''[=MGS4=]'', where she's a major source of motivation for Snake and functions as the protagonists' moral center.
* LapPillow: She acts as one for Raiden in the mission briefing for Act 4 of ''[=MGS4=]''.
* LethalChef: Sunny keeps cooking eggs for Otacon and Snake, but they're usually either over or under-cooked, leading both Otacon and even former Green Beret Snake to constantly come up with excuses to not eat them. She gets better at it and cooks them right at the end.
* MarriedToTheJob: She claims that science is her only love when Raiden asks if she has a crush on anyone in ''Rising'', but it's evident that it's not entirely the truth.
* MeaningfulName: Many of her appearances involve references to the sun, such as her sunny-side up eggs and love of being outside. The latter's even said while the evening sun is setting behind her.
* NoSocialSkills: Hal claims that she's spent her whole life online, and lacks proper social skills. Subverted four years later in ''Rising'' where she is shown to be a pretty well-adjusted and sociable ChildProdigy engineer who works in an aeronautic research institute.
* ParentalAbandonment[=/=]ConvenientlyAnOrphan: Sunny's mother was Olga, who died during the events of the Manhattan Incident to save Raiden and Sunny as well. Her biological father has been completely absent from her life, and there is no clear indication whether or not he's alive at any point in the timeline since the pregnant Olga debuted, or that Olga herself knows who he is, so for all intents and purposes his identity is a complete unknown. Fortunately for Sunny, however, she eventually found herself [[HappilyAdopted a good adoptive family]] in Hal Emmerich, Solid Snake, and Raiden.
* SheIsAllGrownUp: Returns in ''Rising'', with the four year interim turning her into an [[http://images.wikia.com/metalgear/images/0/05/Mgr-Sunny.png adorable]] WrenchWench. If her mother is any indication she's only going to get increasingly gorgeous as she grows up.
* SmokingIsNotCool: Constantly chews out Snake for his smoking habit, especially when he disregards the Nomad's "no smoking" policy. In the briefing for Act 3, she even personally snatches his last cigarette out of his hand and disposes of it.
* SpeechImpediment: Sunny has a slight stutter. It goes away by ''Rising''.
* TechnoBabble: Most of her CODEC conversation in ''Rising'', especially regarding her aircraft designs.
* TeamChef: Cooks for Snake and Otacon in their airbase during the events of ''[=MGS4=]''.
* {{Tsundere}}: Shows shades of this towards George in the epilogue of ''Rising''.
* WholeCostumeReference: Her outfit in ''Rising'' is based on her mother's clothes during the tanker chapter in ''[=MGS2=]'', and the patch on the left leg of her boiler suit is the kana logo Hal designed for Philanthropy.
* WrenchWench: Her position in ''Rising''. See ChildProdigy.
* YoungerThanTheyLook: In ''Rising'', she has the appearance of a young teenager despite being 10 years old.
** Semi-justified in that girls generally hit puberty at around 10-11.

[[folder: Drebin 893]]
[[caption-width-right:300:''[-"Only reason I'm interested in you is 'cause you start a lot of fires."-]'' ]]
->Voiced By: Creator/KeijiFujiwara (JP), Creator/KharyPayton (EN)

->''"Sooner or later, the whole damn human race is gonna be green collars."''

A gun launderer in Metal Gear Solid 4 who replaces ID chips in guns so that they can be used by anyone, for money.
* ActionSurvivor
* ArmsDealer
* AscendedFanboy: The ''Database'' claims he is this to legendary units such as Dead Cell, FOXHOUND, the Cobra Unit, and the Beauty and the Beast unit, which probably explains why he has a photo gallery of the Beauty and the Beast Unit inside of his Stryker, his requiring Raging Raven's Milkhor Grenade Launcher be given to him as a condition for removing its ID tag, and why he would have a Mosin Nagant sniper rifle that's modelled down to the detail after The End's sniper rifle.
* BadassLongcoat
* BigDamnHeroes: In Act 2, he shows up just in time to help Snake and Naomi get away from the [[ZombieApocalypse brain-damaged]] squads of Liquid's [=PMCs=].
* CatchPhrase: "[[PunctuatedForEmphasis Eye. Have. You.]]"
* ChildSoldier: Reveals himself to be a former one to Otacon.
* CoolShades
* DarkSkinnedBlond
* DoubleReverseQuadrupleAgent: Subverted. [[spoiler:Even though he was working for the Patriots the entire time, he's all too happy to see them destroyed.]]
* EverythingsBetterWithMonkeys: A literal case. WordOfGod is that they gave Drebin a pet monkey because he was too boring on his own.
* {{Expy}}: Drebin is [[VideoGame/DeusEx Smuggler]] in all but name. Both characters have the same role, physical appearance, wardrobe and even the same ''voice actor''.
* FingerSnapLighter: One of his many parlor tricks.
* HonestJohnsDealership: Deconstruction: He has done questionable practices, such as injecting potential customers with "transmitters" to essentially spy on them, but his sales, illegal as they may be, actually are genuine and not ripoffs of weapons, and he also makes it fairly clear that he would never betray his customers. [[spoiler: Even when he reveals himself as knowingly working for the Patriots, he's all too happy to see them gone.]]
* JerkWithAHeartOfGold: During the game, Drebin comes off as a rather cold pragmatist, but in the epilogue, it turns out he's actually a nice guy. [[spoiler: Dude even brought doves and flowers for Johnny and Meryl's wedding!]]
* NonHumanSidekick: Little Grey the monkey.
* PunchClockVillain: [[spoiler:He and his fellows are only working for the Partriots out of a lack of any better option. He's relieved when they're destroyed, since it finally allows them to work for themselves.]]
* TheStarscream: [[spoiler: Sort of: Drebin was an agent of the Patriots, but he then reveals that he wasn't upset with Otacon or Snake at all for taking the Patriots AIs offline. On the contrary, he thanked them, as it allowed him and his fellow Drebins to form their own business.]]
* SoulBrotha
* TrademarkFavoriteFood: He's constantly chugging cola.

[[folder: The Beauty and the Beast Unit]]
A unit composed of four insane, power-armored young women codenamed: Laughing Octopus, Crying Wolf, Raging Raven and Screaming Mantis. Ocelot's elite forces in ''Metal Gear Solid 4''. Their Beast halves are voiced by FredTatasciore.
* AmazonBrigade
* AnimalMotifs
* AxCrazy
* BeingTorturedMakesYouEvil: They've all been driven insane by the horrors of warfare, and undergone transformation into super soldiers in the misguided belief that fighting will ease their trauma.
** Note that Laughing Octopus and Raging Raven are the only B&B members to suffer actual torture, though Screaming Mantis overheard other people being tortured.
* BrainwashedAndCrazy: Implied by Big Boss noting that the technology used to seal away his will in addition to his body was similar to the type used to pacify the B&B Corps.
* BreakTheCutie: Each and every single one of the B&B girls suffered this before becoming one.
* {{Dark Action Girl}}s
* FlashStep: In their "Beauty" form, making it NintendoHard to shoot them, tranquiliser weapons or no.
* FlunkyBoss: Raging Raven and Crying Wolf both have soldiers help them, while Screaming Mantis forces people to help her.
* FourGirlEnsemble
* FourTemperamentEnsemble: Deconstructed.
** Choleric: Raging Raven
** Melancholic: Crying Wolf
** Phlegmatic: Screaming Mantis
** Sanguine: Laughing Octopus
* FreudianExcuse: Every one of the Beauties.
* GorgeousGorgon: The B&Bs embody this trope in both the physical sense and the mental one. The first one, Laughing Octopus, is probably the best example; after her armor falls off, she babbles and giggles some more, the camera deliberately avoiding her face... before revealing she's absolutely stunning. In the mental sense, each of the B&Bs reveals a sliver of humanity beneath their psychosis and a desire to be free of the need to kill.
* InSeriesNickname: They are referred to as SNAKEHOUND due to their fascination in wanting to kill Snake.
* InkSuitActor: The Beauty and the Beast Unit's four members were based on models. In the case of Raging Raven, the inspirational model, Yumi Kikuchi, not only lent her appearance to her creation, she even voiced her.
** To a lesser extent, their Japanese voice actors also performed motion capture for the characters.
* [[SirSwearsALot Lady Swears A Lot]]: See Precision-F-Strike. Although most of the characters swear in the series, only Octopus actually went as serious as dropping the F-bomb, making her the first character in the English games and the second overall.
* LaughingMad: Laughing Octopus and to a far lesser extent Screaming Mantis.
* LegacyCharacter: They're named after Ocelot's old comrades in FOXHOUND, [[spoiler:and in Screaming Mantis' case, is possessed by one of them.]]
* MindRape: All of them are victims of mundane versions.
* [[IncrediblyLamePun M.S.]] (MindScrew) [[MsFanservice Fanservice]]: Hands down.
* PoweredArmor
* [[PsychopathicManchild Psycopathic Womanchildren]]: The BATB corps' minds are pretty much stuck in their childhood thanks to their emotional traumas.
* PuzzleBoss: Laughing Octopus and Screaming Mantis.
* QuirkyMinibossSquad: The B&Bs borrow elements from previous MGS bosses; the animal names of the FOXHOUND members, the emotions of the Cobras, and the weapons of the Dead Cell members (Fatman's explosives, Vamp's throwing knives, Fortune's railgun and Solidus' mechanical tentacles and P90). This is entirely intentional because a lot of this game is about flashing back to the past and nostalgia.
** Laughing Octopus is pretty much what Decoy Octopus was, but with the illusory abilities of octopi instead of physically changing into someone (and being a hot blonde girl). Her tentacles and gun of choice both were used by Solidus.
** It's no coincidence that you fight Crying Wolf in the exact same place you fought Sniper Wolf, and in the same way. Crying Wolf's even harder, though, because she's got backup support units and can kill you just by running you over.
** Raging Raven owes most of her inspiration to The Fury, who also flew around and blew up your hiding places. Instead of being surrounded by mostly-aesthetic crows like Vulcan Raven, though, she's got dozens of copies of her wing-units surrounding her, making her fight a needle-in-a-haystack fight.
** And finally, Screaming Mantis is a return to the mind-screw of Psycho Mantis; Instead of psychically flinging objects around, she throws a room full of ''people'' at you, since she can [[PeoplePuppets manipulate their bodies like puppets.]] [[spoiler:Personality-wise, she's even more similar; an otherwise-sanish individual with a psychotic fragment of personality making her do bad things-for Psycho Mantis, it was the Parasite, for Screaming Mantis, it's the ghost of Psycho Mantis.]]
* ShoutOut: They share the code names of the four FOXHOUND members killed in ''Metal Gear Solid'', the weapons of the Dead Cell in ''Sons of Liberty'' and the emotions refer to the Cobra Unit from ''Snake Eater''.
* SpyCatsuit: Their outfits under the armor.
** Note that originally, the Laughing Beauties were intended to be stark naked, but that would have given [=MGS4=] an AO rating beyond a doubt, and they weren't even allowed to have their motion actors do it in the nude. Suffice to say, the SpyCatsuit was a result of this problem.
* TragicVillain: All of them, really. They all endured the horrors of war, which drove them all insane and turned them into the beasts they are now. Rose even expresses pity for them, remarking that all of their stories are absolutely heartbreaking.
* VoiceOfTheLegion: Their armored forms combine a male and female voice, but only when they're in their suits.
* WhereIWasBornAndRazed
* [[WomanInBlack Women In Black]]
* WoobieDestroyerOfWorlds

[[folder: Laughing Octopus]]
[[caption-width-right:300:''[-"People suffering... People hurting... People dying... It's all so fucking hysterical!"-]'' ]]
->Voiced By: Haruna Aimoto (JP), Paula Tiso (EN)

A woman who was forced to kill her family by a cult and pretended to enjoy it. She attacks with giant metal tentacles and advanced camouflage.
* AxCrazy
* CombatTentacles
* InSeriesNickname: Both Snake and Drebin call her "Tentacles" at different points.
* LaughWithMe: Her CatchPhrase.
* PrecisionFStrike: Laughing Octopus drops the F-bomb shortly before fighting Snake, and is notably the first character in the English version of the series (and the second in the series overall, see EVA) to do so.
* ShapeshifterGuiltTrip: Laughing Octopus pulls one during her boss fight after you damage her enough. Actually, a bunch of the forms she takes mock you in one way or another; she even rips off Snake's own signature move by hiding within a cardboard box at one point.
* SlasherSmile: She may be pretty, but she's got one hell of a creepy grin.
* VoiceChangeling: She mimics Otacon and Naomi's voices while morphing into Naomi and the Mk. II respectively.
* VoluntaryShapeshifting: Her [=OctoCamo=] actually appears to be superior to Snake's: whereas Snake's can only do WallpaperCamouflage, Octopus' allows her to actually assume the shape of the Metal Gear Mk. II.
* WallCrawl: Thanks to her tentacles.

[[folder: Raging Raven]]
[[caption-width-right:300:''[-"There you are, Snake! Where's your anger?!"-]'' ]]
->Voiced By: Yumi Kikuchi (JP), Nika Futterman (EN)

A woman who was kidnapped by soldiers as a child and beaten daily. She escaped with the help of some ravens and slaughtered her captors and the civilians they had kidnapped. Her mech allows her to fly and shoot missiles.
* AlliterativeName
* ChewingTheScenery: She's definitely the loudest of the four.
* DarkChick
* EeriePaleSkinnedBrunette
* {{Flight}}: In her armor.
* FlunkyBoss: Her flying minions aren't that dangerous and killing them is supposed to make her an easier target.
* MisplacedWildlife: There are no ravens in Aceh. "Raging Mynah" wouldn't fit the theme, though.
* OnlySaneMan: Well, "sane" doesn't exactly fit for her. Out of all the B&Bs, she's certainly the most coherent in her boss form, giving out some [[IShallTauntYou taunts]] before her fight with Old Snake.
* UnstoppableRage: Duh!
* WingedHumanoid: Her armor gives this appearance off.

[[folder: Crying Wolf]]
[[caption-width-right:300:''[-"Cry for me."-]'' ]]
->Voiced By: Eriko Hirata (JP), Debra Wilson Skelton (EN)

A woman who accidentally smothered her baby brother when he was crying while hiding from genocidal soldiers. She went insane and murdered all the children in a refugee camp, and blamed it on a wolf she hallucinated. Her mech allows Wolf to travel very quickly, and she is an excellent sniper.
* ColdSniper: Inverted. Although she's very skilled at sniping people, she's also shown to break down in tears when doing so, making her anything but cold and emotionless.
* FlunkyBoss: As stated above, she has a support unit of Frogs with her, whom will draw Snake's fire so she can get in a shot. Unfortunately she'll also [[BadBoss occasionally]] run them over when charging Snake.
* TheNoseKnows: She is able to sniff Snake out and accurately shoot at him ''in the middle of a blizzard''.
* NostalgiaLevel: [[spoiler: Crying Wolf is fought in the same Shadow Moses Island snowfield as Sniper Wolf.]]
* SplitPersonality: Specifically, her SplitPersonality is an actual wolf.

[[folder: Screaming Mantis]]
[[caption-width-right:300:''[-"Can you hear the screams?"-]'' ]]
->Voiced By: Mao Yuuki (JP), Andrea Zafra (EN)
->[[spoiler:Psycho Mantis]]: [[spoiler:Creator/ShozoIizuka]] (JP), [[spoiler:Doug Stone]] (EN)

The leader of the Beauty and the Beast Unit. As a child Screaming Mantis was locked in the basement of a torture dungeon and had to live off the polluted water and dead bodies in there, driving her insane. When Snake fights her she is [[spoiler: possessed by the ghost of Psycho Mantis]]. She attacks with two puppets that can control the nanomachines inside everyone.
* DemonicPossession: Variation: Although the ending of the battle implies that [[spoiler: Psycho Mantis possessed her]], it's not so much that [[spoiler: Mantis's spirit actually possessed her]] as it was that Screaming Mantis was injected with nanomachines that contained [[spoiler: portions of Psycho Mantis' psyche]].
* FlashStep: Complete with after-images.
* [[HoistByHisOwnPetard Hoist By Her Own Petard]] / PuzzleBoss: The means to defeat Screaming Mantis is by using the Psycho Mantis doll against her upon procuring it. [[spoiler: Ironic that it had to be the Mantis Doll, seeing how portions of his psyche was implanted into her via nanomachines.]]
* HumanShield: Screaming Mantis is fond of this; she can telekinetically float the bodies of people and control them, and will often use an entire roomful of people to block your bullets.
* MarionetteMotion: Mantis' attack.
* PeoplePuppets: Screaming Mantis's power.
* PsychicAssistedSuicide: Using the same trick Psycho Mantis once did, Screaming Mantis seizes control of Meryl and attempts to get her to shoot herself.
[[folder: Haven Troopers]]
Liquid Ocelot's private military unit; a team of super-soldiers exclusively composed of women. They are nicknamed FROGS.
* AmazonBrigade: All FROGS are females.
* BodyguardBabes: Of both Liquid Ocelot and each B&B member.
* BondVillainStupidity: A squad of them politely waits for Snake and Raiden to converse about philosophy for over two solid minutes whilst they have to the two outnumbered and cornered.
* CeilingCling / WallCrawl: Their gloves and boots make it so clinging onto walls like frogs takes no effort.
* ColdSniper: A good chunk of them are equipped with sniper rifles in Act 3, and make damn good usage of them against Snake and Big Mama.
* CutsceneIncompetence: During gameplay, the FROGS are fairly formidable enemies due to their precision, numbers, and tendency to retreat. However they are extremely unintelligent during cutscenes, ''especially'' in the last level where they have Snake and Raiden cornered and outnumbered and...they patiently wait for the two to converse for ''several minutes'' before attacking.
* DoesNotLikeMen: They all have a chance of exclaiming "You men are all the same!" upon being groped by Snake, lightly implying some misandry.
* DrivenToMadness: By the end of ''Guns of the Patriots'', it's obvious all surviving FROGS have suffered heavy mental breakdowns thanks to the nanomachines getting shut down. One is even fearfully clutching and petting another for no apparent reason at the end of the fifth act.
* EliteMooks: They're extremely formidable compared to all other mooks in the ''Metal Gear'' franchise (at the time), are dreaded by the Rat Patrol, and accompany the game's primary antagonists as personal bodyguards.
* EmotionlessGirl[=/=]EmotionSuppression: Their nanomachines suppress their emotions so expressing or even experiencing fear and remorse on the battlefield is impossible. This is actually present in gameplay, as shown when they encounter emotive weaponry (such as the B&B magazines, the emotive ammo, and the Big Boss mask). Instead of exploding into an emotional fit like it would do to normal soldiers, they simply fall unconscious.
** Strangely, despite this, it's quite obvious they're afraid when being held up by Snake. They flinch and yelp in fear when Snake aims at their head and are even shaking at times.
* FoeRomanceSubtext: During interrogation, it's possible to play with their breasts. Most responses are predictably disgusted or outraged, but some will say "Hey, you're pretty good at that..."
* GasMaskMook: Kinda. Their strange headgear has a vaguely gas-mask-esque appearance, however the mask is likely just for intimidation purposes.
* GenderFlip: They're basically female versions of the Tengu from MetalGearSolid2.
* InASingleBound: Their nanomachines allow them to leap at amazing heights.
* MacheteMayhem: Will draw their machetes in close-quarters.
* MeaningfulName: With their green exoskeletons, abilities to stick onto walls, and amazing jump heights, it's no wonder almost everyone calls them FROGS.
* MsFanservice: Intentionally averted. While almost every prominent female in the ''Metal Gear'' franchise has quite a bit of blatant sexualization (some more than others) weighed on them, especially the villainous ones, the FROGS are almost completely void of sexualization, with realistically sized breasts that lack obvious physics and not an inch of skin to be seen.
** It's possible to grope them, however, but doing so will give the player a ''vicious'' punishment.
* NoBodyLeftBehind: A few seconds after death, their internal nanomachines combust, making their corpses dissolve into ash.
* SuperSoldier: Were the most lethal mooks faced in the series, until the Parasite Unit showed up in ''The Phantom Pain'', thanks to their nanomachines.
