--> ''"It is '''truly''' the end of all intelligence when the '''Lobotomite''' speaks more wisdom than you "geniuses".''
---> '''Dr. Klein'''

A group of some rather... interesting Pre-War Scientists, they will be the first group of people - for a given value of "people" - the Courier will meet after entering the Big MT.

----
!!Provides examples of:
* ArtisticLicenseBiology: As a whole, the group tend to hold rather bizarre perspectives on human anatomy, especially given Klein's belief that fingers and toes are penises...
* BigBad: [[spoiler:They - Dr. Klein in particular - are the real instance of this trope in ''Old World Blues'', and not Dr. Mobius as the player is led to believe.]]
* BiggerBad: They're responsible for the Nightstalkers and Cazadores that have overrun the Mojave, as well as the Cloud and the state of the Sierra Madre.
** They are also the BiggerBad to several antagonists in ''VideoGame/{{Fallout 2}}'' and ''[[VideoGame/{{Fallout3}} 3]]''. Basically, if it was a horrifying application of mad science, it's very likely their research was directly or indirectly responsible. [[spoiler:Dr. Braun and Professor Calvert spring to mind.]]
* BrainInAJar: This explains rather a lot.
* BlueAndOrangeMorality: Centuries of being [[BrainInAJar robotic brains in jars]] have done much to alienate them from normal human thought. The Mentats they're hooked on probably do not help.
* CallBack: [[spoiler:They are indirectly responsible for the Tranquillity Lane simulation in ''Fallout 3'' that the Lone Wanderer's father is trapped in for the first half of the game; for good measure, a cut ending mentions the Think Tank deciding to re-enact Tranquillity Lane in real life.]] It's also implied the tech they used to make them what they are now was tested on [[spoiler:Professor Calvert in Point Lookout]].
* ChewingTheScenery: Klein, Borous, Mobius, [[spoiler:and eventually you, if you choose to convince them that your skull houses the BRAIN OF MOBIUS!]]
* {{Cloud Cuckoo Lander}}s: The Think Tank and sanity went their separate ways a ''looong'' time ago.
* CripplingOverspecialization: Each of them has a specific obsession, and nothing even approaching skills in any other area.
* CowerPower: "None of us has ever been in a fight. No. We do not want that." So they hide inside their dome with pacification fields up that keep anyone from ever pointing weapons at them.
* CurbStompBattle: [[spoiler:If you choose to fight them. Even if you had a hard time with them, the ending states that the fight between them and the Courier was downright humiliating.]]
* DitzyGenius[=/=]GeniusDitz: For the brightest scientific minds of their generation, they all show an astounding lack of common sense and general knowledge, though a good deal of this is due to a mixture of drug abuse, isolation from human bodies, and [[spoiler: sabotage by Mobius]]. For example, they will praise you as a genius if you recommend to Dr. 0 to put a slash through the 0 to indicate it's a number, not a letter.
* TheDreaded: These guys scare ''Ulysses''. Of course, this is primarily due to the Pacification Field that would have made it impossible to defend himself from them.
* DrugsAreBad: Centuries of Mentat abuse have not done them any favors.
* EternalRecurrence: Their mental patterns are on a loop, so they're barely aware of what they're really doing. They don't remember the outside world except in the vaguest sense, and they continuously do the same experiments over and over, learning nothing from them.
* EvilAllAlong: [[spoiler:Well, technically amoral, but you already know that. The problem is that they're manipulating you into giving them what they need to escape Big MT to conduct their experiments on the Mojave and the world at large.]]
* {{Foreshadowing}}: [[spoiler:Whether it is a CallBack or this depends upon the order that you did the [=DLCs=] in, but they are responsible for Christine's near-lobotomisation, the Cloud, the Ghost People, and most of the [[DeathWorld Sierra Madre]] in general.]]
* ForScience: [[CaptainObvious Duh]]. It's even stated as their literal motivation. Not science as applied toward any specific goal, mind you. Just...science.
* HeelFaceTurn: [[BecauseYouWereNiceToMe If you befriend the four other Think Tank members]], [[spoiler:they'll stand up to Dr. Klein when he tries to [[YouHaveOutlivedYourUsefulness get rid of you]] during the final confrontation.]]
* HeroicComedicSociopath: Most of the time. Then you get to see some of their results, which are less funny.
* HumanoidAbomination: They count towards the Abominable challenge, though they're not exactly humanoid.
* HumansThroughAlienEyes: They've forgotten what it's like to be human, having spent most of their long lives as brains in jars. Klein and the rest initially regard you with the suspicion and fear due an alien invader.
* InsufferableGenius: Most of them.
* JerkAss: Klein and Borous always, and 0 if he's in a bad mood. On the other hand, Dala thinks you're just ''fascinating'' and 8...seems...nice. [[TheUnintelligible Maybe]].
* KnowNothingKnowItAll: It's abundantly clear that Dr. Klein has absolutely no idea what the heck he's doing. Dr. 0 is ''seemingly'' almost as bad - his scientific speciality is apparently limited to "taking robots apart" and he tends to destroy his equipment a lot - but he is willing to admit that he is not all that good at the thing he ostensibly specialises in, and he did produce both Muggy and Securitrons that are ''better'' than [=RobCo=]'s Mk. II in some hardware respects despite centuries of being in the open with no maintenance. [[note]]Their [[CrushKillDestroy software]] did not fare quite as well.[[/note]] The rest of the Think Tank seem genuinely skilled and productive in their areas of expertise, [[EvilutionaryBiologist Dr. Borous]] [[DemonicSpiders dangerously so]]. Their general lack of sense can be attributed to centuries of Mentat abuse, as well as that the biogel that the brains float in is corrosive over time. All of the scientists were geniuses when they were human.
** According to WordOfGod, Klein is more the [=Lab Director/College Dean=] than the biggest genius. He's there to push them around and keep the group somewhat focused on research since, relatively speaking, he's the most [[OnlySaneMan sane]] and has the most forceful personality.
* MadScientist: No, really? The fact that they tend to hop themselves up on Mentats doesn't help a bit. They've also been doing virtually the same things over and over and over for more than 200 years. Vivisection ''can'' get boring, you know. Finally, this is ''VideoGame/{{Fallout}}'', and Fifties ''Science!'' was imagined to be a little different from regular old science.
* {{Malaproper}}: Unpossible! And all things robotical.
* TheManBehindTheMan: [[spoiler:Remember the Cloud, the Ghost People, Christine, and the fall of the Sierra Madre in general? Yeah, that was all their idea. Or at least, their doing. Not to mention the Cazadores, Nightstalkers, and the Spore carriers plaguing the Mojave and Zion Valley. They're also indirectly responsible for the Marked Men of the Divide and Tranquillity Lane.]]
** TheManBehindTheCurtain: [[spoiler:Despite all their technological brilliance, the Think Tank aren't much of a threat in person once you get past their defences.]]
* MorallyAmbiguousDoctorate: Even when they were human, they weren't very good people.
* MeaningfulName[=/=]ThemeNaming: [[spoiler:All their names have to do with infinite loops and endless repetition. A 0 (a loop), an 8 (a sideways infinity symbol), Klein (as in Klein bottles), Mobius (as in Mobius strips), Borous (short for Ouroboros, the snake that eats its own tail - though you can point out that it's spelled incorrectly), and Dala (short for mandala, a circular geometric pattern).]]
** Many of their names also hint at their specialties such as Borous, (named after the Ouroboros) being an expert at creating monstrosities, or 8 (a reference to octave) being a sound specialist
* MyGodWhatHaveIDone: Played for laughs in their introduction. After learning that the Courier is still intelligent, Klein starts going on about how they were playing God and created a monster.
* NotSoHarmlessVillain: [[spoiler:Dr. Mobius]] warns the Courier that, despite their quirky personalities and seemingly incompetent harmlessness, the Think Tank are brilliant, dangerous, and amoral, and [[spoiler:will bring untold horrors to the Mojave if they ever escape Big MT.]]
** [[spoiler:A [[http://www.falloutwiki.com/Old_World_Blues_endings#Cut_ending cut ending]] for Old World Blues, with you joining the Think Tank, proves this right.]]
* OnlyKnownByTheirNickname: The Think Tanks' real names have been lost to time.
* OverratedAndUnderleveled: During ''Lonesome Road'', in one of Ulysses' holotapes he remarks how powerful the Think Tank are, stating that they're too powerful for even him to defeat, and that it would take a hundred Elijahs to challenge their full, combined power. Dr. Mobius likewise plays up the difficulty of the Courier facing all five Think Tank members in a straight out fight. However, in-game they're quite a push-over once you override the Pacification Field that prevents you from shooting them and the ending narration notes how easy the battle was. He may simply be referring to what the Think Tank could do if they were focused and [[spoiler: no longer under the influence of Mobius' tampering]], and considering that in one cut ending they [[spoiler: pretty much annihilate the Mojave, destroying the NCR, Legion, and House presence in the process]] it's not inconceivable that this is the case.

!!Dr. Klein
--> ''"THE LOBOTOMITE IS ASKING ME THINGS, O, AND I AM TRYING TO IGNORE THEM. MY PROCESSORS CAN'T IGNORE YOU BOTH AT THE SAME TIME."''
---> '''Dr. Klein'''
--> '''Voiced by:''' Creator/JimWard

The arrogant and condescending leader of the Think Tanks.
----

* TheAlcoholic: Implied by the well-stocked bar occupying the front room of his house at Higgs Village.
* BeardOfEvil: Back when he was human, Klein had a white goatee.
* BigBad: [[spoiler:As the leader of the Think Tank, he functions as this once it becomes clear that they're the real villains of this scenario.]]
* BlatantLies: When 0 rips on Dr. Klein ([[spoiler:assuming you convinced him to side with you]]), the former tells the latter that one of his ideas was copied from the Chinese. Klein, in response, vehemently declares that to be a ''lie!'' ...And that he'd deleted all evidence to the contrary.
* LargeHam: The game itself lampshades this:
-->'''Mission Objective:''' Go talk to Dr. Klein, even though you don't have earmuffs.
* MeanBoss: Frequently condescending arrogant and just plain unpleasant towards both his team members and his temporary allies.
* NoIndoorVoice: Due to someone messing with his volume control.
* OnlySaneMan: Relatively speaking. (By "relatively", we mean he's still out of touch with humanity enough that he's sure your fingers and toes are penises.) Of all the think tank members, Klein seems to be the one most grounded in reality. As a consequence or a cause, he's their leader.
* PunctuatedForEmphasis: "Give. The. Lobotomite. The. Emitter."
* SmallNameBigEgo
* YouHaveOutlivedYourUsefulness: [[spoiler:In the end, he will try to pull this on you. You can either kill the Think Tank or convince him otherwise. If you've befriended the rest of the Think Tank, they'll speak on your behalf. Or you can convince them your skull now [[ChewingTheScenery houses the BRAIN OF MOBIUS]]!]]

!!Dr. 0
--> ''"I have a gift with machines. I can render anything inoperable - preserve them in a non-functioning state."''
---> '''Dr. 0'''
--> '''Voiced by:''' James Urbaniak

A would-be roboticist with a very questionable grasp on technology, a somewhat confusing name and a serious bone to pick with Robert House.
----
* AccidentalMisnaming: His name is often mispronounced as O, AKA: "Dr. Oh", something that he finds frustrating but has stopped bothering to correct. The player can either convince him to take pride in the name 0 or embrace the name O as the "Oh" of discovery.
* TheArtifact: Before he got rewritten into an ersatz Rusty Venture, he was intended to be a sort of newscaster-type guy. You can still hear this a couple of times in his dialogue where he says, "Breaking news!" (Borous and his Beau Weaver voice seem to have taken up the announcer slack in his place.)
* BerserkButton: Mr. House and [=RobCo=] both infuriate him. He can't even stand the fact that the Courier uses a Pip-Boy.
* {{Expy}}: For Rusty Venture from ''WesternAnimation/TheVentureBrothers''. Not only do Dr. 0 and Dr. Venture share the same voice actor, but but similar personalities as well. Both are inventors of dubious competence with a deep inferiority complex towards a superior scientist (Mr. House and Jonah Jr. respectively) as well as drug habits (Mentats for 0 and "diet pills" for Rusty).
* DartboardOfHate: Has a picture of House with knives stabbed into it in his house at Higgs Village.
* TheDogBitesBack: If inspired to take pride of being Dr. Zero, he'll angrily lash out against Klein in the final confrontation.
* FlatWhat: If you suggest to using a slash to tell the letter and number apart, he initially responds with this.
* MillionToOneChance: Considers the probability of Mobius having an absolutely massive Roboscorpion tucked away in his lab to protect him as [[TemptingFate laughably remote.]]
* MyHeroZero: Though it's mistakenly read as the letter "O".
* WalkingTechbane: His specialty is basically breaking robots, Muggy being the exception. He was however able to upgrade upon the Securitrons, but his have since gone [[CrushKillDestroy violent]]. The fact that [[AlwaysSomeoneBetter House is arguably the better (or at least more famous) roboticist]] is the reason that 0 loathes him.
** There are also scattered signs that he is reasonably adept, if imperfect, at [[DittoFighter mimicking cybernetic accomplishments]], including the Securitrons, and the X-13 lab that bears a few of his metaphorical thumbprints.
* [[SpellMyNameWithAnS Spell My Name With A 0]]: He has long since given up on correcting people on his name. With a high enough Intelligence you can tell him to put a slash through the zero and he will ''praise you as a genius''. And when he finally stands up to [[spoiler:Dr. Klein at the end, he mentions the slash, which Klein ''also'' thinks is a stroke of genius.]]

!!Dr. 8
---> '''Dr. 8'''

An acoustician, 8's voice module was damaged prior to the DLC by a previous visitor. As such, he can only communicate in sound waves.
----
* ADateWithRosiePalms: The Courier can reference masturbation in a dialogue path with him, with options ranging from prudishly tip-toeing around the subject to recommending his/her own methods without batting an eye.
* MakeMeWannaShout: As the team's acoustician, 8 provides the player with an upgradeable sonic emitter of his own design... after "warming it up" for you.
* NiceGuy: Despite speaking only in static, 8 comes off as a lot more approachable and helpful compared to the other Think Tanks.
* NoodleImplements: Asking him about "ways of passing the time" and "warming up" the sonic emitter can result in you being rewarded with some of these.
* NumerologicalMotif: Quite apart from his name, he also lives in house #108 at Higgs Village, most of his personal possession appear in groups of eight, and his acoustical specialty can also lend itself towards ''octaves.''
* SilentBob: Dr. 8 is completely unintelligible to most, though 0 seems to be a capable translator for him. With enough intelligence, the Courier can translate it, too... though the players themselves are left with just the Courier's dialogue options to glean what 8 is saying.
* StarfishLanguage: The [=RobCo=] code he communicates through, which sounds like radio static mixed with loud whirring noises; subtitles render it as incomprehensible symbols.
* TokenGoodTeammate: Implied, considering how he (presumably) talks about friendship and has a Meeting People magazine with him. Dala's comments suggest that the rest of the Think Tank prefer him to remain incomprehensible, finding him much too nice and sociable for their tastes.
* TheUnintelligible: Only capable of playing [=RobCo=] termlink protocol [[spoiler: thanks to Elijah hacking his voice module.]] You can understand him through a skill check. At least, the Courier will, so you have to figure out what 8 is saying via the Courier's responses.

!!Dr. Borous

--> ''"Can't splice enough, I always say, especially if you can make a magnificent Cazador!"''
---> '''Dr. Borous'''
--> '''Voiced by:''' Beau Weaver

The incredibly patriotic Head of "Animology, Beastology and DNA-Scrambling Technology" whose memories of high school plague him to this very day. He's also the former owner of Gabe.
----
* BerserkButton:
** Borous' hatred of Communists arguably rivals Liberty Prime. He programmed the Book Chute in the Sink with its all-consuming need to cleanse printed books of their nasty, seditious-thought-provoking material by wiping them totally blank.
** His other one is Richie Marcus, his rival from high school. When acting as the principal in the high school simulation, he is quick to give Richie Marcus [[FMinusMinus a terrible report card]], as well as taking any opportunity to question his sexuality. ("Down the end of the hall is ''ball'' storage, for jocks who like ''balls'', like Richie Marcus!") [[CaptainObvious Even though Richie Marcus has been dead for 200 years.]]
* BlatantLies: Borous claims that he made the Cazadores and Nightstalkers sterile, docile and unable to leave the Big MT. He's probably not exactly ''lying'' as much as he's delusional enough to believe that. If nothing else, [[FalseReassurance they really are as sterile as they are docile]].
* BoldInflation: How he talks.
* CreepyBasement: His house in Higgs Village has one. Specifically, full of animal cages, covered in blood and containing a mutilated teddy bear.
* EvenEvilHasLovedOnes: [[spoiler:It's possible to get him to realize that he loved Gabe and feels sorry about the experiments inflicted on him.]]
* EvilCannotComprehendGood: [[spoiler:If you give him Gabe's bowl, he doesn't understand why he suddenly feels horrible after reminiscing about his dog.]]
* EvilIsPetty: A StrawMisogynist and a JerkAss. In truth, he never got over a jock bullying him and "stealing" a girl who wasn't interested anyway back in school. As a result, as one quest shows, he became a total asshole who would happily take his worst enemy and have him torn apart by vicious mutated animals, just because he never got over it.
* EvilutionaryBiologist: Created Cazadores and Nightstalkers. 'Nuff said.
* FreudianExcuse: Was bullied in high school by one Richie Marcus, and Betsy Bright, the girl he had a crush on, chose to go smoking with Richie rather than go to the dance with him.
* AGodAmI: Just listen to him in the lab he had set up to resemble his old high school. He even calls himself a god and acts [[GodIsEvil like a heartless asshole with absolute power]].
* InsistentTerminology: For Borous, it never simply science. It's '''Science!'''
* KickTheDog: Used his dog Gabe as a test subject, turning him into a giant, vicious cyberdog pumped up on Psycho.
** PetTheDog: [[spoiler:When you bring him Gabe's dog bowl, he mourns his cruel treatment of the one creature he truly cared about.]]
* LargeHam: He's always speaking as if he was the narrator of a 50's sci-fi film. The game itself lampshades this:
-->'''Mission Objective:''' Say hello to Dr. Borous. Carefully.
* MyGodWhatHaveIDone: Borous comes to this realization when you bring him Gabe's dogbowl. He quickly suppresses his feelings however, or at least tries to.
* NoIndoorVoice: Incapable of speaking in anything but an announcer-like voice; he does, however, use a relatively calmer tone when [[spoiler:the Courier shows him Gabe's feed bowl]].
* PatrioticFervor: Hates communists almost as much as he hates Richie Marcus and Betsy Bright.
* PsychopathicManchild: Never really grew up past his high school years, a fact he makes evident in his school-themed dungeon, where he also reveals he's what would happen if an embittered high school nerd who wanted to be a mad scientist really became one.
* ReversePsychology: Bringing him Gabe's bowl fills Borous with absolutely crushing guilt, [[EvilCannotComprehendGood even if he can't understand why]]. Spell it out for him, and he'll quickly act to suppress those feelings. But there's another dialog option where you disregard all those moral quandaries and just take his side, [[ReplacementGoldfish just like Gabe would have]], which allows those feelings to fester for longer before Borous can understand their meaning. This manifests [[spoiler:in the final confrontation with Klein]]: If they're suppressed, Borous will speak of you as a research subject that is too valuable to kill. If they're not, [[MoralityPet he'll show true remorse and draw comparisons to your loyalty and Gabe's]].
** In the end, Borous will "side" with you no matter what you say, but it effects the research he shares with you every few days after the fact. [[{{Squick}} Test subjects get shown the things he found inside other test subjects]]. But loyal companions inspire him to find more productive ways to nurture life, resulting in his creations laying eggs that he shares with you.
--> '''Dr. Borous:''' Look at THESE. Aren't they quite look-worthy? All dripping with the residue of creation. Wondrous.
* StalkerWithACrush: Based on one of the files you have to retrieve in the high school test listing the after-school activities of a girl.
* TheStarscream: His ranting in the X8 facility reveals he plans to take over Big Mountain someday.

!!Dr. Dala
--> ''"Shh, little organs. Go to sleep in your tanks. Dala loves you."''
---> '''Dr. Dala'''
--> '''Voiced by:''' Jocelyn Blue

The Head Chief Researcher of Minerology (as well as possessing degrees in 211 other fields), Dala has a not-so scientific fascination with the human body.
----
* ADateWithRosiePalms: Dr. Dala has...somewhat more ''biological'' needs than her colleagues, to an extent that rapidly becomes disturbilarious. Apparently even when she was human she used, ahem, ''assistance'' (at least until the other Think Tank members got on her case for stealing batteries).
* BoyishShortHair; Back when she was human, she kept her hair fairly short.
* ConstantlyCurious: Apparently, she has degrees in Curiosity and Advanced Curiosity. In person, most of this curiosity is fixed on very specific subjects...
* FantasticArousal: Dr. Dala is, uh, interested in human bodily movements. Even breathing is of interest.
* GirlsLoveStuffedAnimals: She had a thing for collecting actual teddy bears back when she was human, as evidenced by the dozens of them scattered about her house. However, since her transformation, she's lost interest in the genuine article and adopted Lobotomites as her... new teddy bears.
* HouseOfBrokenMirrors: Investigating her house at Higgs Village reveals that every single mirror in the building has been smashed, possibly as part of RageAgainstTheReflection.
* TheImmodestOrgasm: The mission "[[DoesThisRemindYouOfAnything Coming]] Out Of Her Shell" features her engaging in a bizarre and somewhat robotic version of this.
* TheNicknamer: Dala calls the Courier a "teddy bear," another tie-in to her little obsession.
* NightmareFetishist: By Think Tank standards, she's ended up as a rather literal example as this; given that most of them see organic bodies as disturbing and grotesque, Dala's fascination and open arousal with "formology" is clearly this to Klein and co.
* OmnidisciplinaryScientist: Dala is evidently a combination of a botanist, toxicologist and a physician/surgeon. She has 213 doctorates, several in fields she's invented herself. For good measure, she's one of the more competent Think Tank members.
* RoomFullOfCrazy: Her chamber in the Think Tank is host to several teddy bears and mannequins, and her house in Higgs Village is full of teddy bears and broken mirrors, including a scene set-up as if they were to watch her model clothing.
* TheSmurfettePrinciple: The only female in the group.
** WomenAreWiser: Also probably one of the most stable members of the group, too... relatively speaking.
[[/folder]]

[[folder:The Inhabitants of the Sink]]
--> ''"A toaster is just a DeathRay with a smaller power supply!"''
---> '''The Toaster'''

--> '''Voiced by:''' Creator/JimWard (Sink CIU, Sink Auto-Doc), Beau Weaver (Book Shredder), Roger Cross (Biological Research Station), Veronica Belmont (Light Switch 01/02), Jocelyn Blue (Sink appliance), Sunil Malhotra (Muggy), Rashawn Underdue (Blind Diode Jefferson), Jace Hall (Toaster)

A group of appliances at the Sink, the Courier's home base during Old World Blues. Each one has their own personality.

----
!!Provides examples of:

* ArtificialIntelligence
* AttentionWhore: Light Switch 02
--> ''"If I made out with the Sink, would you pay more attention to me?"''
* AxCrazy: The toaster, of all things. His purpose in life is to 'murder' other toasters and appliances, ripping them into their component parts. If the Courier ends the DLC with bad karma, [[spoiler:the toaster goes on to found and be the center of his own cult, laying waste to all unfortunate appliances.]]
* BettyAndVeronica: The light switches. 02 is the Betty, 01 is the Veronica.
* ButtMonkey: Muggy. He's been designed to be an in-universe TakeThat against Mr. House and Securitrons, has a neurotic NeatFreak personality, a weird obsession with mugs, and was programmed to be fully aware that he was programmed to be that way. Nobody in Big MT uses mugs anymore, depriving him of a job, he's gotten damaged by the toaster, and he gets "[[BlackComedyRape seeded]]" by the biological research station. For good measure, a bad ending for him features Muggy suffering a flat tire ''just'' out of reach of the coffee cup he'd planned to retrieve next - resulting in his brain exploding in frustration.
** ThrowTheDogABone: If you find Higgs' Village, the ending states that he finds himself stuck exactly where he wants to be: a place filled with dirty mugs, plates and things that need cleaning.
* CardCarryingVillain: The toaster is quite possibly the most hilarious example ever.
* CasanovaWannabe: The biological research station. It really wants your seed, baby!
* CloudCuckoolander: All of The Sink's appliances, to some degree or another, save perhaps Sink Central Intelligence.
** The Book Chute thinks penguins have a gland in their tear-ducts that converts salt water to fresh water.
* CompanionCube: ''All'' of them.
* DoubleEntendre: Nearly all of the Biological Research Lab's responses to the Courier, and the Courier can respond in kind.
* EarnYourHappyEnding: [[spoiler: Nothing if you breeze through Old World Blues. However, if you take your time and explore critical locations in the Big MT and end with Good Karma, the Sink all contribute to make the facility less of a DeathWorld and manage to live happily ever after. The Auto-Doc deactivates the walking suits of armor that plague the facilities, the ([[NamesTheSame actual]]) Sink develops antitoxins to combat the Innovative Toxins Plant, the toaster never carries out its plans for world destruction because the other sink personalities team up to destroy it, Muggy ends up happy in a place where he can clean mugs, Central Intelligence ends up feeling secretly glad to be with the other personalities, the Biological Research Station [[YourHeadAsplode doesn't blow up]] and just tries to get together with the X-22 facility, and even Blind Diode Jefferson, hundreds of years later, saves the Big MT from sonic invasion using the frequencies you fetched for him. And with the aforementioned Good Karma, at the ending...]]
--> [[spoiler:There were Old World Blues, and New World Hope. [[CrowningMomentOfHeartWarming And hope ruled the day at the Big MT]]. ]]
* {{Expy}}: The toaster is basically the ''Fallout'' equivalent of Murray from the ''VideoGame/MonkeyIsland'' series. Only a toaster.
** The toaster is also a subtle ShoutOut to a cut toaster from ''VideoGame/{{Fallout 2}}''. Although the one from ''Fallout 2'' would [[Series/RedDwarf only ask if you wanted toast.]]
* GirlOnGirlIsHot: Light Switch 02 thinks she can [[AttentionWhore get you to pay more attention to her]] if she makes out with the Sink. Both identify as female.
* ItemCrafting: Once fully upgraded, some of the Sink appliances can convert the many VendorTrash items found in the Mojave into useful items, as follows:
** The Sink can fill empty bottles with water to make Purified Water, a useful healing item.
** Muggy can break down various ceramic objects into useful crafting materials.
** The Toaster can break down broken technology into useful crafting materials, as well as powering up some weapons.
** The Book Chute can convert ruined or burned books into blank books, which can eventually be made into stat-boosting Skill Books with certain recipes.
** The Biological Research Station can convert certain plants into an all-purpose sludge that can grow any number of plants, letting you turn worthless ones into helpful ones. Combined with Muggy giving you empty syringes, they can help you easily craft an effectively infinite number of stimpaks.
* JerkWithAHeartOfGold: Despite being aloof, condescending and opposed to the idea of reactivating any of the Sink's other personalities, the Central Intelligence remains loyal and helpful to the Courier at all times. In some endings, it can even admit to being impressed by the Courier's progress in mapping the crater, and ultimately grows to accept the other inhabitants for the sense of community they've brought.
* TheJeeves: The Sink Central Intelligence. To the point that it will constantly call you "sir", even if you're a woman and point this fact out, because it was programmed to and not likewise programmed to say "ma'am" or leave out the honorific altogether.
* JiveTurkey: Blind Diode Jefferson, your jukebox. He also says he'd sing the Blues, but he can't because the bits of him that actually played music were stripped out.
* HarmlessVillain: As much as he would like to [[OmnicidalManiac burn the world]], there's really only so much the Toaster can do.
* {{Keet}}: Muggy's adorable, perpetually cheerful [[IncrediblyLamePun mug]] makes him seem like this, but it's subverted: he's a tiny ball of hate, self-loathing and neuroses who is ''well aware'' of being all these things, which just fills him with even more rage.
* KillItWithFire: If the toaster had its way... Fortunately, its tiny heating coil restricts it to simply heating up Saturnite, and then only if you let it. The weapons created this way will set your enemies alight instead.
* LargeHam: The toaster, again. And Muggy.
** IncomingHam: "Ahahahaha! I am on-line once again! Tremble world before my electric heating coil of doom!"
* MagicPlasticSurgery: The Auto-Doc can do this once the appropriate holotape is found.
* NeatFreak:
** The sink (not to be confused with The Sink, which is your base). The idea of a filthy wastelander touching her is quite repulsive. Except for after the ending, in which she says she becomes a bit... lonely without you around.
** And Muggy. Although he intentionally leaves all of Dr. 0's mugs and plates filthy out of spite.
* OmnicidalManiac: Guess who?
* OrwellianEditor: The book chute's job is to take any "seditious" books you have, and remove all of their text, all in the name of keeping citizens from thinking for themselves. Won't that keep you happy and docile, citizen?
* RedScare: The book chute is especially hateful of [[DirtyCommunists Communists]], and regards any free thought as seditious.
--> ''Look out! Communist! ...No, false alarm. It was just a plate.''
* RefugeInAudacity: The biological research lab [[DoesThisRemindYouOfAnything seeds]] Muggy, tricking him into thinking a mug fell down his chute.
* ReluctantPsycho: Muggy, who is all too aware how crazy he's been made, which just leaves him an even worse wreck.
--> ''I love mugs so much, I just might kill myself!''
* RoboticPsychopath: The toaster, as stated above.
* SesquipedalianLoquaciousness: Sink Central Intelligence and, surprisingly, the Book Chute:
-->'''Book Chute:''' Do you know what 'proletariat' means? If so, congratulations! You're very well-read and erudite... ''for a Communist.''
* TalkingInYourSleep / NonSequitur: The Sink Auto-Doc is prone to these.
-->'''Auto-Doc:''' zzz... nurse... come quick... this man has a severe case of shoe-lung...
* TakeThat: Muggy the miniature Securitron was made by 0 to spite House. Muggy is aware of this and ''hates'' him for it.
* ThrowTheDogABone: In his good ending, Muggy finds a peaceful place to reside in at Higgs Village, filled with plenty of homes that he can clean and tidy up forever. Except for Dr. 0's, which he ignores out of spite.
* TitleDrop: At the end of the expansion, Blind Diode Jefferson does this for the next DLC.
--> ''"Guess you'll be putting on your travelling boots again, hitting that old '''lonesome road'''."''
** {{Irony}}: Blind Diode Jefferson is voiced by the same actor as Ulysses, and Lonesome Road is more or less centered around Ulysses.
** Also, he defines the term "Old World Blues": a longing for the glories of the past.
* TokenEvilTeammate: The Toaster again.
* TrueCompanions: The ending states that the Sink AIs became something of a family unit with even the Sink Central Intelligence getting accustomed to the others. And right after you come out from the Think Tank center, defeating them through blood or word? They all [[CrowningMomentOfHeartwarming give you a great big cheer]] [[CrowningMomentOfAwesome in celebration of you being the new boss.]]
* UndyingLoyalty: The Sink Central Intelligence, specifically to the Courier. As of the ending, it's prepared to wait as long as necessary for you to return.
* VillainousBreakdown: Sort of. When you tell the toaster that the world was already destroyed in nuclear fire, he's saddened because it wasn't by him. He gets over it by the next time you talk to him though, vowing to be the world's second destroyer.
* YouHaveResearchedBreathing: Some of them require upgrades to do what should be pretty simple stuff. The sink, for instance, which allows you to get a drink of water, requires a module for filling up ''empty bottles'' with water.

[[folder:The Stealth Suit Mark II]]
--> ''"Hello. It's nice to meet you. Who can I hide you from today?"''

--> '''Voiced by:''' Veronica Belmont

Yep, the Stealth Suit is a character. Of a sort. You find her in one of the labs. When equipping her, she will use Stimpacks and Med-X on you as needed.

----
!!Provides examples of:

* ArtificialIntelligence
* DeadpanSnarker: Has a variety of things to say should you attempt to sneak with your Pip-Boy light on.
* EvolvingWeapon: Armor, really, but you can upgrade her via tests.
* TheMedic: As stated above, she will heal you when you are injured.
* RobotGirl: Suit, technically.
* RoboShip: It's fairly evident she's quite fond of you. [[invoked]]
** It seems like the Infiltration program in X-13 has a bit of an attachment to her as well, if the epilogue is anything to go by.
--> The infiltration program in X-13 felt spent, having repeatedly upgraded the Stealth Suit until it could upgrade it no more. [[DoesThisRemindYouOfAnything It felt warm, fulfilled, and a bit sluggish]]. It realized not long after, the Stealth Suit had left it [[NotStayingForBreakfast without so much as a note on the nightstand]]. So the infiltration program sent out Robobrains into the wastes [[StalkerWithACrush looking for its wayward technology]].
* TryNotToDie: Uses words to these effects when applying stimpaks.
* {{Yandere}}: Juuuuust a little bit.

[[folder:Dr. Mobius]]
[[quoteright:240:http://static.tvtropes.org/pmwiki/pub/images/DrM_5577.jpg]]

--> ''"Well, there's many things they have forgotten sitting in their bowls. [[BreadEggsMilkSquick Friendship. The thrill of discovery. Love. Masturbation.]] The usual."''

---> '''Voiced by:''' Creator/CamClarke

The antagonist of Old World Blues, he's been threatening the Think Tank with intelligence-eating Robo-scorpions that keep them huddling in their base until he comes to destroy them. [[spoiler:Then you meet him and get his side of the story.]]

----
!!Provides examples of:

* AbsentMindedProfessor: Due to a combination of senility, drug addiction and his brain being corroded by the biogel. [[spoiler:It's kinda sad, really, especially since he dedicates as much of his remaining mental capacity as he can towards containing the Think Tank.]]
* AffablyEvil: He rambles on placidly about nothing very much when you speak to him and seems genuinely surprised you're there to fight. It takes some effort for him to recall that he ever had plans at all, let alone brilliant schemes -- but he assures you that if he had, they would indeed have been brilliant! Then he'll give you some Mentats with the air of a grandfather handing out sweets. It's very hard to imagine how he could be less threatening. [[spoiler:Because, of course, he's not the real threat.]]
* AntiVillain: [[spoiler:He's actually a kindly, half-senile old man. His mad scientist tendencies are the result of tripping on Mentats and Psycho, and the threats are only to distract the Think Tank from trying to escape.]]
* BigBad: [[spoiler:Only by necessity.]]
** NonActionBigBad: [[spoiler:Assuming he actually counts as bad.]]
* BrainInAJar
* CrouchingMoronHiddenBadass[=/=]TheChessMaster: Despite seemingly being [[spoiler:a friendly, harmless, half-senile old man]], it's clear that Mobius cooked up a genuinely complex and effective plan to [[spoiler:keep the Think Tank safely sealed inside the Big MT, and also manipulated the Think Tank into providing you with the means to get your brain back and re-install all your stolen organs]].
* DesignatedVillain: [[spoiler:[[InvokedTrope Invoked]], by both him and the Think Tank. The Think Tank designated him a villain to get you to help them escape the Big Empty. Mobius designated himself a villain to make sure the TT would ''stay'' in the Big Empty rather than bring terror to everything outside.]]
* DrGenericius
* TheDragon: The X-42 Giant Roboscorpion is effectively this for him.
* GoodAllAlong: [[spoiler:He's trying to keep the Think Tank from escaping the Big MT and inflicting their atrophied morals and dubiously logical [[ForScience Science!]] on the world at large.]]
* GracefulLoser: If you tell him that [[spoiler:his plan failed because the Think Tank only needs the blueprints to the various technologies he's been keeping from them, which they now have access to]], his response is a cheery "Oh well, I tried".
%%* HeroAntagonist
* KingMook: Mobius is noticeably tougher than the other Think Tank members, which even gets lampshaded in dialogue if you talk to him about [[spoiler:trying to fight the Think Tank]].
** PostFinalBoss: Although his stats are objectively pretty good, he's a fairly mediocre fight compared to all the DemonicSpiders in the Big MT you've been fighting as regular enemies. The real final boss of ''Old World Blues'' was the [[HumongousMecha X-42 Giant Roboscorpion]] guarding his lab. [[spoiler:In fact, you don't even have to fight him at all, given that he's really a harmless, well-intentioned old man.]]
* LargeHam: He's voiced by Cam Clarke, so this goes without saying. [[spoiler:A good dose of Psycho helps a lot as well.]]
* MadScientist: [[spoiler:Only in the literal sense that he's insane; he isn't malicious at all, and in fact has the strongest moral compass of the Think Tank]].
* {{Malaproper}}: He uses words like "raisin" instead of "reason" and other such mix-ups. Quiet instead of quite, dessert in the place of desert, etc.
* NinjaPirateRobotZombie: He uses robot Radscorpions that shoot [[FrickinLaserBeams lasers]] at you.
* OnlySaneMan: [[spoiler:For a given value of sane, anyway - more sane than the Think Tank, which isn't saying much, and then only when he isn't hopped up on Psycho and Mentats. Might be more accurate to say that he's the only member of the group who realizes the moral consequences of their "[[ForScience Science!]]"]]
* ProperlyParanoid: Mobius studied the post-apocalyptic economy extensively and correctly guessed that bottlecaps would be used as currency, which is why the Sink accepts them.
* RedRightHand: He's missing an eye-monitor and the others look to be in bad condition.
* ShoutOut:
** [[WesternAnimation/{{Futurama}} It doesn't just seem like coincidence that he is a disembodied brain that says raisin instead of reason]].
** He also has plenty of [[Film/Plan9FromOuterSpace Plan 9s]], just in case.
* TheStoner: While all the Think Tanks are Mentats addicts, Mobius' drug habits are even worse, including Psycho and Jet. He claims he gets the dispensers mixed up.
* TokenGoodTeammate: Formerly one to the Think Tank. [[spoiler:Mobius was the only one to come to the realization that their constant experiments will do more harm than good and is trying to keep them contained without actually hurting them.]]
* WellIntentionedExtremist:
** [[spoiler:He only broadcast crazy messages and unleashed the Robo-Scorpions so the scientists of the Think Tank wouldn't escape and destroy the rest of the world. Well, that and he tends to be high as a kite when he threatens them. The implication is that he gets high specifically so he ''can'' threaten them and make it seem genuine. Klein requires an absurdly high speech check to trick him during the endgame, so it would thus follow that Mobius (who sounds like a kindly, slightly-senile grandfather) would need some help sounding evil.]]
* WhenAllYouHaveIsAHammer: His Robo-Scorpions are pretty much his only way of solving problems and he is very enthusiastic about using them, though it would be hard not to be. ''You'' try saying you're going to unleash the [=Robo-Scorpions=] without [[LargeHam hamming it up]].

[[folder:'''SPOILER''' Character]]
!!The Courier's Brain

-> ''"Do you know how much more you can get done when you're not constantly looking for places to urinate? It's quite a lot, I can tell you."''
-> '''Voiced by:''' Suhil Malhotra

A brain who has a few things to say to you.

----
!!Provides examples of:

%%* BrainInAJar
* EnemyWithout: Not really, but your brain isn't that happy with you.
%%* [[WalkingSpoiler Floating Spoiler]]
* {{Jerkass}}: The Courier him/herself can outright ask why his/her own brain is "such a dick."
* LivingMacguffin: Pretty much what everyone in Big MT, including you, needs to further their plans.
* InsufferableGenius: Tries to act like it's better than you. If you're a drooling imbecile, you can piss it off even further.
%%* NeatFreak
* NotSoDifferent: When it lambasts the Courier for constantly charging into danger, the Courier can counter that since it's...well, his/her brain, then those actions are just as much its responsibility as his/her's. The brain, in turn, counters that those are all simply glands at work, and thus the Courier ''is'' the one to blame. But with a high enough medical skill, the Courier points out that the brain ''contains'' most glands, [[FunnyMoments unless it's trying to pin everything on the thyroid]].]
* ScrewYourself: [You can actually hit on your own brain with the Cherchez La Femme/Confirmed Bachelor perk, to its incredible disgust.
-->"Are you... Are you coming on to me?! Sweet Lord, I don't even have the words for how repugnantly wrong that is!"
* SnarkToSnarkCombat: It's deeply sarcastic towards you and the Courier has the option to throw this right back.
* SplitPersonalityMerge: Possible at the end.
* TalkingToYourself: Leading the Courier possibly engaging in SnarkToSnarkCombat with their own brain.
* VocalDissonance:
** Even if you're a woman, your brain talks to you with a male voice because female voice modules are hard to come by in the Big MT. Also, if you're playing a character with a low INT stat (and thus extremely dim), your brain will justify its boosted intelligence and lack of HulkSpeak by saying that the biogel that surrounds it is filled with ground-up Mentats.
* WhatTheHellHero:
** Your brain does not enjoy venturing in filthy dilapidated Vaults, dealing with creatures such as Cazadores on a relatively daily basis, or going on a pointless quest of vengeance.
** It also angrily questions whether or not you've bothered bathing even ''once'' since coming to the Big MT.
** If you're playing as a female Courier and slept with Benny, your brain will have some choice words about that, as well.
** It's most annoyed however, about having been shot twice in the head whilst housed in your skull, which apparently is ''your'' fault.
