[[folder:The Ghostbusters]]

!!Peter Venkman (Creator/BillMurray)


-->''"Back off, man; I'm a scientist."''

* AntiHero: Snarky, arrogant, conceited, womanizing and sometimes a [[{{Jerkass}} real jerk]], but still a good man. He softens up quite a bit in ''Ghostbusters II''.
* BecomingTheMask: Particularly in the first movie, there's something to this. He puts on an ironic persona of being a know-it-all big shot, but by the end, he's forced to back up his braggart ways and become a real hero.
* BerserkButton: The novelization of the first film reveals one; don't talk bad about his family. When a magazine does an investigative story on Pete's past and his father's history as a carnival impresario, Peter deliberately lets a ghost roam free in their offices until they agree to publish a retraction.
* BrilliantButLazy: He is a fairly smart guy. If only he cared enough to do anything with his smarts. He has [=PhD's=] in both psychology and parapsychology, but uses mostly the psychology one to help him get together with girls.
* BunnyEarsLawyer:
-->'''Dana''': You know, you don't act like a scientist.
-->'''Peter''': They're usually pretty stiff.
-->'''Dana''': You're more like a game show host.
* ConMan: Venkman is the least sincere of the four, exploiting the field of "parapsychology" to swindle universities, push nonsense papers all day, flirt with his research subjects, and basically get paid for doing nothing.
* TheCasanova: If all those phone messages he gets in the game means anything. He seems to have become quite popular with the ladies. Despite this, though...
** CasanovaWannabe: He is still not capable of winning over everyone. At least it seems that way till they start going out with him...
* ChivalrousPervert: He's interested in dating his female students, however, he refuses to take advantage of [[spoiler:Dana possessed by]] Zuul.
* CloudCuckoolandersMinder: [[NoodleIncident Egon apparently tried self-trepanation, but Peter stopped him]].
* DeadpanSnarker: Definitely.
-->"You're right; no human being would stack books like this."
* TheFace: Peter is the group's ambassador and generally does the talking.
* FlatEarthAtheist: At the start of the second film, even after dealing with real ghosts and an extradimensional deity, he still thinks the only reason a person would write a book about the end of the world would be to make a quick buck from gullible readers. Possibly justified by his line to Dana in the first film saying ''most'' people who say they see ghosts are nutjobs.
** And with his producer after an episode of his show:
-->'''Producer:''' (famous paranormalists refuse to appear on Venkman's show) "They think you're a fraud."
-->'''Venkman:''' "I ''am'' a fraud."
* FreudianExcuse: Having an absent, sleazy conman for a father certainly explains a fair amount of his personality.
* FreudianTrio: Ego
* TheGadfly: Especially in the sequel.
* GoodIsNotNice: He's a sarcastic wise-ass, despite being one of the series' lead heroes.
* GuileHero: Can trick and bluff his way out of any pinch.
* TheHero: It's a subtle thing, but if anyone in this group fill this role, it's Peter. The other members will generally do more of the heavy lifting, but Peter is higher profile and speaks for the group.
* JerkWithAHeartOfGold: Though you have to look ''really'' hard to find the heart of gold in the first film. It's much more evident in ''Ghostbusters II'', and he is generally much kinder in the cartoon series as well. In the video game, he seems to have lost some of that heart and the Jerk seems to have resurfaced. A funny jerk, but a [[{{Jerkass}} Jerk]] none the less.
* TheKirk: An acerbic version. He nets all of the chicks and saves the day by breaking established rules (like EPA codes) and rebelling against authority.
* KnightInSourArmor: Despite his actions to the contrary, Peter is in fact more likely to do the right thing than not. He has his moments, when he can get away with it. He is a {{Jerkass}} for sure, but never would he step down from helping someone who ''really'' needs it. Notably, in the first film, he's willing to go back to jail (and quietly) if it turns out they're wrong about Gozer.
* TheLeader: Not so much a leader as designated spokesperson or front man. Peter is the ladies' man of the group, and while he's less normal than Winston, he's more capable of relating to other people than either Ray or Egon. In the cartoon series, he is also the one who generally decides whether or not the Ghostbusters will take a given job.
* LovableCoward: For all his bravado, he's not exactly a brave guy; he'll step up to the plate if necessary, but ''very'' reluctantly, and will happily allow someone else to go first.
* TheMillstone: Every problem the 'Busters have to deal with in the original film is caused by him. It's his freewheeling attitude that gets them kicked out of Columbia, his overt come-ons with Dana nearly cost them their first customer, and his standoffishness with Peck is what gets the containment grid shut down. Every one of these incidents is subverted because Venkman's cleverness and quick tongue always end up fixing the problems he causes.
* NiceJobBreakingItHero: Perhaps if he hadn't antagonized Peck so much and just showed him around, Peck wouldn't have gone and shut down the power grid.
* ObfuscatingStupidity: He is a very intelligent man, but he comes off more like a CasanovaWannabe. He obviously doesn't have any real interest in parapsychology or psychology. Despite all this, the very fact that he was able to become a scientist in those fields speaks volumes of what he is capable of when he works at it.
* PapaWolf: Even though Oscar is not his child, he did his part to protect him from Vigo.
* PetTheDog: At the start of the film, he's got very few good qualities but Dana sort of becomes a MoralityPet of his. He does become more heroic at the end of the film, and for all his sleaze, he is so not going to sleep with a woman under the influence of a major specter.
* PhonyPhonyPsychic: A charlatan in the field of telepathy (later 'promoted' to a cable TV host on a paranormal talk show) finds himself getting dragged along on a hunt for real ghosts.
* PreAssKickingOneLiner
--> "All right--this chick is ''toast!''"
--> "Let's show this prehistoric bitch how we do things downtown!"
--> "Viggy, Viggy, Viggy. You have been a bad monkey!"
* PunchClockHero: He's OnlyInItForTheMoney and treats what he does as a the paying job it is, not some selfless mission or higher calling for the good of mankind.
* TheSlacker: He certainly tries to be this. In the first movie, he only goes to help Dana because he wanted to get into a relationship with her. Also in the game, he was busy getting coffee while the Rookie and Ray are being attacked by Stay Puft and his minions. He's basically reluctant to do anything unless some kind of personal gain is involved.
* TheTrickster & TokenEvilTeammate: He is purposely contrary to people, inciting them to become aggravated with him. Peter seems to not care much for their feelings though and goads them on. He is willing to mock or patronize even people in places of authority, whereas Ray and Egon would be more-easily cowed and cautious. Though he usually shows more discretion with these people than to the average Joe. May be unrelated, but perhaps his attitude to higher authority improved after what happened with Peck.
* TrustMeImAnX: "Back off, man. I'm a scientist."

!!Egon Spengler (Creator/HaroldRamis)


-->''"I collect spores, molds, and fungus."''

* {{Adorkable}}: How could Janine resist such a handsome, shy, soft-spoken genius with NoSocialSkills?
* AdmiringTheAbomination: Admires some of Ivo Shandor's work in the 2009 game, but is also quick to admit that he was also very evil.
-->'''Ray:''' "Stick to the Light Side.'''
-->'''Egon:''' "It's hard."
* BadassBookworm: Not necessarily a TropeCodifier, but definitely one of the originals.
* BewareTheNiceOnes: Egon completely ''flips his shit'' when [[spoiler:Peck accuses the Ghostbusters of causing the containment breach, something that Peck caused]].
* CloudCuckoolander: Not to the extent as Ray, but still.
* CollectorOfTheStrange: Molds, fungus and spores, mostly. He may even possibly find the scent of them attractive.
* CreepyChild: This is implied in the second movie. While Ray and Egon are in baby Oscar's room, Egon reveals he never had any toys when he was a child. Ray is curious and asks if he really never had any toys, and Egon responds by saying he had half a Slinky once (he straightened it).
** The novelization went further, listing a number of strange experiments young Egon enacted which got him ostracized by his peers. "I think you've been spending too much time with Egon" was a common sentiment among his friends' parents.
* ForScience: Let's just say he can get rather disturbing with how far he'll go for the sake of science. Tricking people into thinking they're going to counseling when, in fact, he just wanted to test if slowly increasing the heat would alter their moods. Wanting to conduct a gynecological examination on Dana while investigating the baby carriage incident. Then there was that [[NoodleIncident drill thing]]...
-->That would've worked if you hadn't stopped me!
* DeadpanSnarker: Egon has his dry comedy moments such as the musical ectoplasm.
--> Venkman: "Dooooooo"
--> Stantz: "Reeeeeeeee"
--> Egon: "Egonnnnnn!"
* [[DefrostingIceQueen Defrosting Ice King]]: Hard to tell, but he smiles considerably more in the second film.
* {{Expy}}: The Medic from VideoGame/TeamFortress2 is a pretty clear Egon expy, from his similar uniform, AwesomeBackpack, suspiciously similar goggles, round glasses, AmbiguouslyJewish [[note]]despite the fact that the lore kind of goes back and forth on whether or not he's supposed to be an ex-Nazi[[/note]] MadScientist tendencies... Medic even fights ghosts each year around Halloween!
* FreudianTrio: Superego
* GadgeteerGenius: He makes all of the equipment the Ghostbusters use. In fact, he works on so many gadgets, the other characters [[LampshadeHanging asked him how he can produce so much]]. He tells them he's been doing an experiment where he sleeps for an average of fourteen minutes a day.
* HeroicComedicSociopath: He seems rather detached from other peoples' feelings, and occasionally misleads or disturbs people for his own amusement, but his ultimate goal, apparently, is for the common good.
* HotScientist / HotTeacher: At least, Janine, Kylie, and his college students think so. He's not entirely happy about it.
-->"I think [my students are] more interested in my epididymis."
* TheLeader: In the cartoon, he trades off with Peter in this role. While Peter generally decides if they will take a job, once there the group usually defers to Egon's expertise.
* MadScientist: Close to a TropeCodifier, but a heroic version (though he still can get a bit disturbing). Egon is primarily a theoretician and field strategist who mainly wants to study the things which the Ghostbusters encounter, rather than destroy them.
* MorallyAmbiguousDoctorate: He seems to be mildly sociopathic, as he routinely puts people in unpleasant situations [[ForScience for scientific purposes]] and shamelessly lies and jerks people around just to see what kind of reaction he gets. The best example of this is in the beginning of the sequel when he tests the effect of human emotion on the environment by ruining a couple's marriage and giving a little girl a puppy only to take it away again.
* NightmareFuelStationAttendant: He is already shown to be a bit odd, but nothing too serious. Just a bit of a nerd. The whole "mold, fungus and spore" thing were certainly strange but nothing horrifying. Then we get a glimpse into his life before the Ghostbusters--he used to be a coroner. This isn't too bad, though. ''Then'' he says that he does it as a hobby now. Oooookay...
* NiceGuy: Although he's a mad scientist, whose methods are questionable, Spengler has a soft side only seen by his friends and Janine.
* NoodleIncident: Egon tried to drill a hole in his head at some point. All we know is Peter stopped him before he could do it.
* NotSoStoic:
** The scene where he flips out when Peck accuses the Ghostbusters of causing a massive explosion that Peck himself caused.
-->"[[YourMom YOUR MOTHER]]!"
** In the video game, as he and the Rookie are going up the elevator, suddenly they are treated to a phantom image of the Spider Witch and one of her victims. Egon is quite shaken at seeing this. In fact, he seems quite nervous throughout the Spider Witch's level. He also angrily tears up a sign prohibiting the Ghostbusters from entering the hotel at the beginning of the level.
*** His uncharacteristic edginess may be explained by to his own in-game notes: Egon admits he is an arachnophobic.
** His reaction once to getting snarked at by a serious {{Jerkass}} in the IDW comic is a scream and an attempt to ''throttle him''!
* ObliviousToLove: How the animated series and IDW comics interpret his relationship with Janine.
* ShoutOut/ NamedAfterSomebodyFamous: Named for Egon Kisch (a famous Czechoslovakian journalist who, among other things, helped popularize the Golem of Prague and claimed to be descended from its creator, Rabbi Loew) and [[DichterUndDenker German philosopher]] [[Literature/TheDeclineOfTheWest Oswald Spengler]].
** In turn, John Egbert nicknames a cat in {{Webcomic/Homestuck}} after ''Egon'', albeit with a cat-related pun (Dr. ''Meow''gon Spengler).
* TheSmartGuy: While Ray is also intelligent, Egon is TheStrategist of the group.
* SpecsOfAwesome: He's the biggest nerd in an 80s sci-fi film -- what did you expect?
* TheSpock: Pure intellect -- they didn't dub him "The Head" for nothing.
* SweetTooth / GeniusSweetTooth: Describes New York City's telekinetic energy in terms of Twinkies, using his own as a visual aid. Accepts a Nestle Crunch bar as a reward.
* ThemeMusicPowerUp: In the cartoon series, most of these occur either while Egon is formulating strategy or when he does something that helps the rest of the group succeed.
* WhenHeSmiles: Sometimes when he does smile it comes across as [[TheUnsmile ominous or threatening]]. However when he does it for genuine reasons it's nice to see, such as when he's assuring Dana that he won't use anything to hurt Oscar during a routine Check-up.

!!Raymond "Ray" Stantz (Creator/DanAykroyd)


-->''"Well, this is great. If the ionization-rate is constant for all ectoplasmic entities, we can really bust some heads... in a spiritual sense, of course."''

* {{Adorkable}}: He's sweet-natured, nerdy, and a bit of a goof-ball.
* AdmiringTheAbomination: He gets boyishly excited by a lot of the weird, gross and terrifying stuff they encounter.
* BewareTheNiceOnes: Ray is honestly the nicest guy you will ever meet, but if you mess with any of his friends, whether you be human or ghost, he will not take it lightly.
** He also hates it when kids are being threatened.
--> '''Ray:''' (''to Vigo'') You want a baby? Go knock up some willing {{hellhound}}. Otherwise I am giving you to the count of three to march back in that painting!
* ButtMonkey: If he's not being manipulated or slapped around by Peter, he's getting attacked/possessed by one demonic entity or another.
* TheCameo: In Film/{{Casper}}. Generally considered a non-canon appearance by fans due to how cowardly it makes Ray look.
* CloudCuckoolander: Has this in spades. He believes that an undersea mass sponge migration he once witnessed was paranormal despite the fact that the sponges barely moved a foot.
* DemonicPossession: This has happened to him far more than any other character in the series. It's to the point where the other characters [[LampshadeHanging lampshade]] it every time he becomes possessed or slimed.
* DitzyGenius: For the guy who was behind the creation of the proton packs and the Ecto-1, he sure doesn't have a lot in the common sense department.
* DrivesLikeCrazy: During the [[HesBack They're Back]] montage in the second film, Peter has a look of panic as Ray is driving the Ecto-1A to a new case.
** However, in the first movie and in other points during Ghostbusters 2, Ray is shown to be a perfectly competent driver. [[spoiler: Peter looks worried because that short clip is from a deleted scene after Ray looks into the painting of Vigo's eyes. In the cut scene, he drove Ecto-1A like crazy through traffic... because he was possessed by Vigo and aiming to ''commit murder-suicide''. He's snapped out of it by Winston punching him in the face, slams on the brakes before Ecto can run head-on into a tree, and explains that he just felt an urge to drive into said tree and end it all. Peter warns Egon to keep an eye on Ray and not even let him shave. The comics featuring The Real Ghostbusters characters in Ghostbusters 2 [[https://www.youtube.com/watch?v=EX5kjwaK4eg included the scene.]]]]
* DysfunctionalFamily: The novelization for the first movie paints his family out as one. His parents disappeared and are presumed dead, and his brother and sister refuse to talk to him or each other for what we can assume are very petty reasons.
* TheEngineer: While Egon is typically the group's [[TheStrategist strategist]] during missions, Ray is the mechanic and practical inventor. He built the proton packs and the stuff on the Ectomobile, and also designs something called a "Ghost Bomb" in the cartoon series.
* ForScience: Far more mild than Egon, though.
* FreudianTrio: Id
* GoodSmokingEvilSmoking: Good on Ray's part. He's seen with a cigarette in almost every scene in the movies.
* TheHeart: He's considered this by the rest of the Ghostbusting team.
* HollywoodAtheist: An interesting case. In a short scene toward the end of the first movie, Ray and Winston are alone in Ecto-1, and Winston asks if Ray believes in God. His response is a brief "Never met him." It's rather strange to hear this coming from someone who sees strange spiritual events every day. Ray goes on to quote the Book of Revelations regarding the End of Days, showing that he has some Biblical knowledge. So he may not be an atheist per se--he might be an agnostic.
** In the 2009 game he mentions he spent some time in a seminary. Whether this was because he wanted to go or if it had something to do with the Stantzes being a top-notch DysfunctionalFamily isn't elaborated on, but it's more or less confirmed that he was, at one point in his life, religious.
* HotBlooded: Out of everyone, he is the most passionate when it comes to ghosts and the supernatural, and is the first one to rush headfirst into the unknown.
* LeeroyJenkins: "GET HER!"
** Leading to a hilarious brick joke. "Go GET HER...Ray!"
* TheLancer: He's this to Peter, making it an interesting aversion of the traditional roles; Ray is the [[ThePollyanna idealistic]], innocent one whereas Peter is the [[DeadpanSnarker snarkier]], self-centered one.
* LastNameBasis: Unique among the main characters in that he generally refers to everyone except Winston by their last name. This seems more personal preference than reflective of his feelings towards them, however.
** ... Until the second movie, when he starts nicknaming everyone instead.
* MadScientist: A heroic example.
* ManChild: His sheer delight at sliding down the fire pole (and at the rest of the fire station) in the first movie would put him here even if nothing else would. In general, however, where Peter is dry and cynical and Egon is clinically rational, Ray tends to have a lot of childlike enthusiasm for what they do.
** In the cartoon, he sleeps with a Stay-Puft plushie, and the team picks him to stand in for a six-year-old child to help catch the Boogeyman. He's also ''overjoyed'' to see a plush dog similar to one he owned as a child used as a prop and immediately rushes over to pick it up and cuddle with it.
*** In the second movie, [[spoiler: when he fails to possess Oscar, Vigo decides Ray's just as good]]. The fact that Vigo specifically requested a child to live through speaks volumes of Ray's man-child tendencies.
* TheMcCoy: Though more agreeable than his partners, he does jeopardize their safety with his headstrong personality.
* NiceGuy: He's a decent person who genuinely wants to help others by using the technology the Ghostbusters create to study the supernatural and defend the city.
* NiceJobBreakingItHero: He unwittingly chose the form of the Destructor.
* NightmareFetishist: The dream sequence he had may suggest how deep his nightmare fetish goes.
* SpellMyNameWithAnS: Stantz in the movies and video game, Stanz in ''WesternAnimation/TheRealGhostbusters''. It's generally accepted that the cartoon misspelled Ray's surname, as opposed to how fans argue over whether Winston's is Zeddemore or Zeddmore.
* VitriolicBestBuds: With Peter, who relentlessly teases and takes advantage of him, even going so far as manipulating him into mortgaging his parents' house. In spite of that, it's obvious that they care about one another, as evident in their final goodbye to each other when confronting Gozer at the end of the first movie.

!!Winston Zeddemore (Creator/ErnieHudson)


-->''"If there's a steady paycheck in it, I'll believe anything you say."''

* AllThereInTheManual: The entirety of Winston's backstory is relegated to secondary works, and he receives little characterization in the films.
* BadassBookworm: In ''WesternAnimation/TheRealGhostbusters'' he's depicted as loving mystery stories, which helps the Ghostbusters "bust" the ghost of an Creator/AgathaChristie {{Expy}} by completing her UnfinishedBusiness. When the Ghostbusters bust the [[{{Literature/Jabberwocky}} the Jabberwock]], he quotes from the Creator/LewisCarroll poem named after the creature.
* BadassMustache: Although he's clean-shaven in the cartoon and the second movie.
* TheBigGuy: A former marine who provides the muscle and firepower in a team otherwise composed of scientists.
* CulturedBadass: He is shown to be a fan of opera and seems to be the most civil-minded of the Ghostbusters.
** When he does earn his doctorate (in the video game), it appears to be in either History or Egyptology.
* DeadpanSnarker: Must be a job requirement.
* GeniusBruiser: He is a very competent member of the Ghostbusters team. In the video game, while the others were chasing after the Grey Lady, he was looking through the newspaper archives for info on her, though he pretended he was looking up a baseball game. In the novelization of ''Ghostbusters'', it is shown he was once in the Marines and has experience with different kinds of technology, which helped him get into the busting more easily than one would think a new hire would.
* GenreSavvy: When Egon explained the growing problem with the containment unit, all Egon had to do was use a Twinkie as an example.
* NaiveNewcomer: Averted; he gets the hang of his job ''very'' quickly.
* OnlyInItForTheMoney: His original reason for joining in the first place.
-->''As long as there's a steady paycheck in it, I'll believe anything you say''.
* OnlySaneMan: Compared with his colleagues, the quirky paranormal scientists, he has more common sense.
* PunchClockHero: Took up ghostbusting purely to get a steady paycheck.
* RealMenLoveJesus: Or, in his case, Jesus' style.
* SixthRanger: Doesn't appear until the second half of the first movie, which explains why he tends to be left off some promotional materials for the movie, especially during its theatrical release.
* SkepticismFailure: The cartoon reveals that he didn't believe in the supernatural when he joined the Ghostbusters. That doesn't last long, of course.
* SpellMyNameWithAnS: Is it "Zeddmore" or "Zeddemore"?
** Both of the movies and the game spell it Zeddemore, leading people to believe ''WesternAnimation/TheRealGhostbusters'', which used "Zeddmore," misspelled Winston's surname.
* TokenMinority: The team black guy.
* UnfazedEveryman: He takes the whole Ghostbusting business very well and he seems to be the most normal out of all of its members. No major idiosyncrasies to make him quirky or anything; he is just a normal guy with a job as a spectral exterminator.
** Perhaps ironically the lack of any major defining quirks among a group as odd as the Ghostbusters ''is'' his quirk.
* YanksWithTanks: He was originally in the Marines before he became a Ghostbuster, which may provide another reason why it didn't take him long to get the hang of the equipment. He's also been depicted as being the best shot with the proton gun.


* AllThereInTheManual: It's never really explained where he came from in the movies proper, but according to Dan Aykroyd he's the ghost of Creator/JohnBelushi.
* BigEater: When first encountered, he's scoffing his way through a room-service trolley.
* BlobMonster: Spherical, and made of slime.
* CreatorCameo: His voice is provided by series director Ivan Reitman.
* FatAndSkinny: The Fat to Louis' Skinny.
* HarmlessVillain: The Ghostbusters caused MUCH more havoc than he did, and he never actually hurt anybody.
* HeelFaceTurn: He helps Louis (and the other Ghostbusters to an extent) out near the end of the second movie.
* HiddenDepths: When Ray hooks him up with a text-to-speech computer in the cartoon, he's quite eloquent. He also solves a math problem Egon's been stuck on for awhile (although he misplaces the decimal point).
* LawyerFriendlyCameo: Shows up in {{Webcomic/Homestuck}} as the icon on protagonist John Egbert's t-shirt, but rendered in SuperDeformed anime style, and only referred to as "Slime Ghost". However, John makes blatant references to ''Ghostbusters II'', and the comic doesn't pretend it ''isn't'' Slimer.
* {{Mascot}}: Particularly in the cartoon series.
* MeaningfulName: Deliberately. In the animated series, Ray gave him the name "just to annoy Peter."
* NonHumanSidekick: Most likely -- see below.
* OurGhostsAreDifferent: The first ghost seen not to be the spirit of a deceased human being.
* TeamPet: In the game and other media.

!!Janine Melnitz (Annie Potts)


-->''"I've quit better jobs than this!"'' *answers phone* ''"Ghostbusters, whaddya want!?"''

* AmbiguouslyJewish: Like Egon.
* BadBadActing: As seen when she and Louis are roped into acting in a commercial for the company.
--> "''Who'' are you going to call?"
* BeleagueredAssistant: Poor Janine, she is in charge of every single secretarial thing that goes on in the Firehouse. Despite being so swamped, she's able to keep everything going smoothly. Despite all she does, her boss Peter continues to refuse to hire more help around the Firehouse to ease her workload. He also expects her to come in even if there is a mass exodus of the city. Her sassy demeanor makes a lot of sense once you consider all of the work and abuse she has to deal with.
** Not to mention the babysitting she had to do for three nutcase {{Mad Scientist}}s before Winston added a bit more sanity.
* [[UsefulNotes/AmericanAccents City Girl Squawk]]: She provides a great example of this accent.
* DeadpanSnarker:
--> "Dropping off or picking up?" in response to a policeman arriving at the door.
* TheFace: Janine is the receptionist for the four man organization; a notably interpersonal role. One scene in the first movie has her trying to convince a customer of their professionalism.
* FieryRedhead: In the second movie. She got a makeover to look more like her cartoon counterpart.
* {{Meganekko}}: Wears big, thick glasses -- which give her a "bug-eyed" look, as Venkman comments.
* OnlySaneWoman: Until Winston shows up. After that, they trade off on the "babysitting the mad scientists" duty.
* SarcasticDevotee: Despite her very sarcastic interaction with her boss, she remains his loyal secretary.
* SassySecretary: She's very vocal about any grievances with the job.
* UnfazedEveryman: She is surrounded by men who hunt ghosts, half of whom are [[MadScientist mad scientists]]. She even has a ghost in a cage close to where she works that the busters keep as a "pet." Not once has she ever batted an eye at any of this.
* UnusuallyUninterestingSight: She seems to take the ghostbusting business pretty well, never showing any signs of it being out of the ordinary.

!!The Rookie (model Ryan French)

Appeared as the player character in the 2009 video game, served as the team's prototype weapons tester (i.e. field-testing the weapons and upgrades that could explode at any moment and emit an alarmingly high amount of radiation and exotic particles regardless).

* {{Adorkable}}: One of his most remarkable traits is his clumsiness. He fell off a roof, fell down a trap and accidentally zapped a tree with his pack.
* ButtMonkey: He is made to do quite a few dangerous tasks--touching an inter-dimensional portal that could lead ''anywhere'', go it alone in the huge cemetery that wasn't there yesterday, get trapped alone in a waterlogged hotel floor with malevolent candelabras... this dude puts up with a lot.
* CanonName: Given in the IDW comics, may only be canon to said comics (so far).
** '''Realistic:''' Bryan Welsh
** '''Stylized:''' Chad Fuller (Male)/Maddie Collins (Female)
* CollectorOfTheStrange: Since the player can collect some special items, you can turn the Rookie into this. One of the items he can collect is a possessed toilet.
* CreatorCameo: In a manner of speaking. In the PS3 version of the game, associate producer Ryan French served as the base for the Rookie.
* FunnyBackgroundEvent: When he accidentally blasted a tree with his proton pack, and when he was left hanging with a high five. Also he goes plummeting down a trapdoor.
* HeroicMime: Never says a word aside the occasional scream or gasp.
* MauveShirt: His name tag just says "Rookie", since it's more convenient. Peter doesn't want to remember his name so they don't get attached, since he's testing out prototype equipment...
* PutOnABus: After the events of the game, he leaves New York in order to expand the franchise.
* NaiveNewcomer: His name is ''very'' accurate.
* NiceJobBreakingItHero: His attempt to recapture Slimer at the beginning of the game leads to the containment vault accidentally being damaged and several ghosts being unleashed.
* NoNameGiven: [[EnforcedTrope Enforced]]; the other Busters don't want to feel too attached to him due to the HighTurnoverRate of the team's other rookies.
* SixthRanger: Joining a previously established team.
* TheVoiceless: See HeroicMime, the Rookie is mute aside from gasping or screaming once or twice. Given a speaking role in the comics after he's sent to Chicago.

[[folder: Villains]]

!!Walter Peck (Creator/WilliamAtherton)


-->''"Forget it, Venkman! You had your chance to cooperate, but you though it would be more fun to insult me. Well, now it is my turn, wiseass."''

A representative of the Environmental Protection Agency. He's highly skeptical and cynical. Especially toward Peter.

* AmoralAttorney: He only aims to sue the Ghostbusters out of spite for their cause, but in reality is just a money grubbing agent.
* ArbitrarySkepticism: Surrounded by news articles and tv interviews about the ghosts the Ghostbusters have caught, yet insists it's all an elaborate scam.
* CoveredInGunge: But hey, at least it was marshmallow.
* ThePeterPrinciple: He has absolutely ''zero'' understanding of the Ghostbusters' technology, yet legally has the right to screw with both it and them. [[PillarOfLight Hilarity does not ensue]].
** It's actually worse than that; nothing he does or accuses them of is within his jurisdiction. He has no legal standing whatsoever for his actions, he's just a petty tyrant who thinks being a federal regulator means he can do anything.
* CruelAndUnusualDeath: Averted; he survives it.
* HarmlessVillain: Debatable. The containment unit gets blown up because of him in the first film. Peck generally doesn't do anything truly lethal to the Ghostbusters directly, but he does act as an independent DiscOneFinalBoss who manages to either restrain or delay the Ghostbusters, which gives the real villains more time or freedom to act.
* HateSink: Peck with his imperious self-righteousness and his {{Jerkass}} NeverMyFault belligerency is clearly designed to inspire a burning hatred in the audience. When he has the Ghostbusters arrested for the explosion when it is clearly his own fault, the whole audience wants to punch his lights out.
* {{Jerkass}}: Where to begin? He harasses the Ghostbusters based solely on rumors. He orders the containment grid to be turned off despite the warnings of the Ghostbusters and a Con Ed technician's reticence against doing so, resulting in the release of all the ghosts therein. ''Then'' he has the nerve to have the Busters arrested for the disaster ''he himself caused''!
** JerkassHasAPoint: His initial request to see the containment grid was reasonable. It is his job to make sure people like the Ghostbusters are operating with safe equipment, and in fact the Ghostbusters' containment grid could cause a massive explosion in a densely-populated area. After getting crudely brushed off by Peter, however, [[JumpingOffTheSlipperySlope he overreacts and orders the grid's immediate deactivation]]. If Peter had cooperated instead of treating Peck and the EPA as an enemy from the start, they could have avoided the ensuing meltdown.
*** Peter had a valid point though: nothing he was accusing them of was actually in EPA jurisdiction. His actions were completely illegal, and Peter rightfully counters that he is willing to sue for wrongful prosecution. The Nuclear Regulatory Commission would probably have wanted to have a word with them, though.
*** Tellingly, notice that when Peck returns for his fateful "shutting off the containment system" visit, he brings with him one police officer and one guy in a workman's outfit and hard hat - i.e. ''no one trained to deal with the things he accused the Ghostbusters of.'' If there is any evidence for Peck pulling things out of his ass in service of his witch hunt, it's this.
* NeverMyFault: Peck loudly and blatantly blames the Ghostbusters for causing an explosion when it is clearly obvious in front of multiple witnesses that he himself is personally responsible for the disaster when he ordered the containment grid turned off.
* ObstructiveBureaucrat: A government bureaucrat who, in his quest to obstruct one business, obstructs the business of the entire world.
* RedHerringMole: In the video game, the Ghostbusters think he's the BigBad, [[spoiler:but it turns out he's an UnwittingPawn]].
* SharedMassHallucination: He thinks that the Ghostbusters were using hallucinations to make ghosts.
* StrawCharacter: Peck is the quintessential Reagan-era caricature of a government inspector.
* UnusualEuphemism: "This man has no dick."
--> "Well, that's what I ''heard''!"

!!Eleanor Twitty AKA Gray Lady (Ruth Oliver)

* AncientKeeper: [[spoiler:She's spent decades keeping the Gozerian Codex in her last resting place.]]
* AntiVillain: Type II.
* AscendedExtra: Originally she was merely just the first ghost the Busters came across, then after scaring them off she wasn't mentioned again. In the video game, she was given an entire level where we were introduced to who she was and shown her deep connection to the event in the game as a node in the spectral circuit flow.
* BewareTheQuietOnes: [[spoiler:Despite seeming to be just a normal ghost, she ends up having the power to control the entire library, as well as ghosts that are not known to work together. Hurt her and you'll regret it, even if it takes nearly a century.]]
* TheChessmaster: [[spoiler:In the game, she purposely lured the Ghostbusters to her library by taking control of some ghosts and making them cause a ruckus. All this to get them to go after her murderer/ex-boyfriend so as to finally get her revenge.]]
* FingerOnLips: Shushes them when they disturb her reading. Disturb her reading again and she goes ape.
* FogFeet: It seems to be the main way one tracks her.
* OneWingedAngel: Her "angry form."
* SitcomArchNemesis: To Ray; he really wanted to [[IncrediblyLamePun get her]] after scaring him.
* ScaryLibrarian: Especially in her angry mode.
* SnubByOmission: Her initial response to the Ghostbusters is to ignore them.
* SpookySilentLibrary: Her chosen domain, [[CaptainObvious obviously]].
* RevengeAgainstMen: [[spoiler:Her EX-boyfriend]], not the Ghostbusters.
* UnfinishedBusiness: [[spoiler:Subverted. After thinking they had helped her pass on by taking her book, she suddenly reappears and laughs maniacally as she transforms into her angry mode.]]
* VoluntaryShapeshifting: She has a disturbing tendency to shift between a quiet plain librarian [[OneWingedAngel to a raging grotesque ghoul. Though the others suspect this was also part of it - that the fight was not only to give the Ghostbusters the book, but so that they would wreck the room and uncover the path to the ghost world where her murderous ex was hiding.]]
* WomanScorned: Oh yes...
* WoobieDestroyerOfWorlds: [[spoiler:Her boyfriend used her to get at her rare book collection. When this is discovered, she dumps him and revokes his pass to her collection. He then kills her, trapping her in the library she tried to protect. It is soon shown, despite her circumstances, she isn't going to mope about. Instead she'll spend her afterlife plotting the downfall of her ex-boyfriend. She succeeds, with the help of the Ghostbusters.]]

!!Gozer the Gozerian (humanoid form: Slavita Jovan) (humanoid form: voiced by Paddi Edwards)

* EldritchAbomination: A non-cephalopod variety.
* EightiesHair: A mean flat-top.
* EvilSoundsDeep: Gozer speaks with a raspy, deep voice.
* AFormYouAreComfortableWith: Apparently Gozer's trademark. When it arrives to cause an apocalypse, it forces the denizens of the world its about to destroy to choose the form it will end them with. Ray chooses a marshmallow man, which he believes to be the least threatening of all the transformations (and probably would have been had it not been the size of a skyscraper).
* HoistByHisOwnPetard: The door Gozer used to enter man's world is also the thing that pushed it back out.
* HumanoidAbomination: At least Gozer took the form of one. Its true form has never been revealed.
* IHaveManyNames: Also known as "Gozer the Traveler," "the Destructor" and "Volguus Zildrohar."
* TheNotSoHarmlessPunishment: Ray tries to think of a form for Gozer that couldn't possibly hurt anyone. Guess what?
-->[[NiceJobBreakingItHero "Nice thinking, Ray."]]
* NoBiologicalSex: Gozer only takes on forms with characteristics of other genders. In truth, it has none of its own.
* NotQuiteDead: Returns as the Stay Puft Marshmallow Man in the 2009 game, but in this game is fried to a crisp.
* OmnicidalManiac: Seems to be Gozer's main goal. It kills everyone, its summoners and all else in its way.
* OtherworldlyAndSexuallyAmbiguous: Gozer the Gozerian, the Sumerian god, in the final confrontation. The boys are surprised that s/he's a "girl", but clearly s/he is both.
-->'''Ray''': It's a girl.
-->'''Egon''': It's Gozer.
-->'''Winston''': I thought Gozer was a man.
-->'''Egon''': It's whatever it wants to be.

* PhysicalGod: And anyone who isn't can PERISH!
* RedEyesTakeWarning
* SissyVillain: Chooses to appear in an androgynous form leaning towards feminine.
* VoluntaryShapeshifting: From a woman covered in bubbles to a giant marshmallow man. Truly, Gozer doesn't seem to care what form it takes.

!!Zuul and Vinz Clortho ([[spoiler:Creator/SigourneyWeaver and Creator/RickMoranis]])
* AffablyEvil: Vinz enthusiastically gushes to Egon about how Gozer has destroyed previous worlds and seems to expect humans to be genuinely excited about being destroyed. Vinz even politely assists Egon in mundane tasks and seems more like an excited puppy than a demonic invader.
* BewareTheSillyOnes: Vinz.
* CloudCuckoolander: Vinz clearly isn't all there, though part of it may have been due to possessing [[spoiler:Louis Tully]].
* CoDragons: To Gozer.
* DemonicPossession: The possessed forms of [[spoiler:Louis and Dana]].
* EvilSoundsDeep: Zuul.
* {{Hellhound}}s: They're known as Terror Dogs.
* MsFanservice: Zuul [[spoiler:at least while he's in Dana's body]].
* QuirkyMinibossSquad: For Gozer.
* RedEyesTakeWarning: They both have glowing red eyes, which do shine through the eyes of their human forms.

* BigBad: Of the second movie.
* BlackEyesOfCrazy: When possessing Ray.
* BlobMonster: He controls the living ''River of Slime'' beneath New York.
* BodySurf: One of his more frightening powers.
* CardCarryingVillain: His nicknames: The Scourge of Carpathia, The Sorrow of Moldovia, which he calls himself. What others call him: Vigo the Torturer, Vigo the Cruel, Vigo the Despised, and Vigo the Unholy.

* EmotionEater: He feeds on human negative energy.
* EvilOverlord: "On a mountain of skulls in a castle of pain, I sat on a throne of blood."
* TheEvilPrince
* EvilSorcerer: In his {{backstory}}.
* {{Expy}}: Possibly of Vlad the Impaler aka [[Literature/{{Dracula}} Count Dracula]].
* AGodAmI
* HarmlessVillain / VillainDecay: In the game, he's reduced to nothing more than his painting, unable to do much of anything aside from talk and make the player feel uncomfortable. To add insult to injury, said painting is owned by the very people who beat him: the Ghostbusters.
* HoistByHisOwnPetard: [[spoiler:A version of Vigo's empathic slime empowered with ''positive'' emotions is what ultimately does him in]].
* HornedHumanoid: Grows two stumpy blood-colored horns after being sucked back into the painting during the final confrontation.
* IHaveManyNames / NamesToRunAwayFromReallyFast: Also known as Vigo the Cruel, Vigo the Torturer, Vigo the Despised and Vigo the Unholy.
-->'''Peter:''' Wasn't he also Vigo the Butch?
* KubrickStare
* ObviouslyEvil
* RasputinianDeath:
-->'''Ray''': He didn't die of old age, either. He was poisoned, stabbed, shot, hung, stretched, disemboweled, drawn and quartered... Just before his head died, his last words were "Death is but a door, time is but a window: I'll be back."
* {{Reincarnation}}
* [[SealedEvilInACan Sealed Evil In A Painting]]: When first encountered.
* SorcerousOverlord: He was this in past life.
* SpookyPainting: Dana comments that the painting gives her chills, even before the paranormal shenanigans begin.

!!Tony and Nunzio Scoleri (Jim Fye and Tim Lawrence)
* AllThereInTheManual: Their first names (as well as the identity of their actors) were given in an article about the film's special effects.
* FatAndSkinny: Tony is the skinny one, Nunzio is the fat one.
* FatBastard: Nunzio is disgustingly overweight ''and'' a murderer.
* GigglingVillain: Tony has a really high-pitched AnnoyingLaugh as probably his only vocalization.
* GlowingEyesOfDoom: Their eyes glow brightly.
* TheHyena: Tony.
* KnightOfCerebus: To the extent that they're the only regular ghosts (in the movies, anyway) shown to be actively dangerous as opposed to merely a nuisance.
* PsychoElectro: They're the ghosts of convicted murderers and covered with surging electricity because they got executed via electric chair, although it's unclear if they can actually use it as a power.
* SiblingTeam: They're ''literal'' BashBrothers!

!!Ivo Shandor

* AscendedExtra
* BadassGrandpa: [[spoiler:He captured an EldritchAbomination from another world. Granted, it was only a baby; still impressive]]. He was the head of the cult of Gozer, [[spoiler:and he made himself a god!]]
* BigBad: [[spoiler:Of the video game.]]
* BodySurf: [[spoiler:For most of the game, unknown to the Ghostbusters, Ivo has been possessing the mayor of New York since before the game even started.]]
* DeadlyDoctor: He performed quite a few unnecessary surgeries in his time.
* EvenBadMenLoveTheirMamas: He kept a painting of his mother in his church to Gozer. Despite most everything else in the church being run-down, his mother's painting is the only thing that is still pristine. Even after being underwater for who knows how long.
* EvilOldFolks: He is a cult leader who was involved with quite a few bloody sacrifices to Gozer as well as making buildings that would bring about the end of the world. Apparently he thinks mankind is too sick to survive.
* EvilPlan: To wipe out the bastard humans, of course. Building Dana's apartment, storing energy and everything else works toward this goal.
** MyDeathIsJustTheBeginning: [[spoiler:He and his cult made sure this would happen even after their deaths. Also they had an alternate plan in case Gozer had issues the first time, and already had it set into motion.]]
* AGodAmI: [[spoiler:Ivo was upset that Gozer was beaten not once, but twice. So he decided he would take the energy he was originally going to give to Gozer and empower himself with it. He goes into it with the big speeches and everything.]]
* GhostlyGoals: Definitely Type B.
* HumansAreBastards: Apparently this was his reason for trying to bring about the end of the world. After UsefulNotes/WW1, he felt mankind was far too sick to survive. [[{{Hypocrite}} Kind of ironic]] [[{{Hypocrite}} considering what ''he'' had done]] [[{{Hypocrite}} to his fellow human beings]]. Even before he started to bring about the end to life.
* MadDoctor: See below.
* MadScientist: An evil one to combat the Ghostbusters two good ones.
* MalevolentArchitecture: Dana's apartment building which Ivo designed specifically for causing horrors to come upon the world. [[spoiler:Ivo also worked on the Sedgwick Hotel, Library, the Natural History Museum and his own personal island.]]
* MisanthropeSupreme: He deeply hates all human beings, considering them vermin and "too sick to survive."

!!Spider Witch (Erin Gray)

* AllWebbedUp: Kind of goes without saying. Her entire realm is covered in spider webs and hanging human bodies, and the boss arena in the 360 and PS3 versions of the game is all of this.
* AnimalMotifs: Spiders, [[CaptainObvious obviously]]. Even in life, her spider obsession seemed to be a major characteristic of herself.
* AxCrazy: She didn't need to be paid to kill someone, as she liked it so much she did it anyway.
* AscendToAHigherPlaneOfExistence: Possibly. We are not too sure if she was human or not. If she ''was'' human then, after her death, she became a demigod-level spirit being.
* BloodLust: Her suite, after she disappeared, was found to be painted in blood. Her victims hung on the ceiling drained of said blood, after she dragged them around to smear it on the floor.
* TheCollector: She collects men's dead bodies ''and'' their souls, making them her eternal slaves.
* EeriePaleSkinnedBrunette: As if being a spider-obsessed BlackWidow wasn't enough for her, she had to be this too.
* [[EveryoneCallsHimBarkeep Everyone Calls Her Spider Witch]]: She was a professional BlackWidow who brutally murdered her victims not for money but for a twisted hidden reason. She became known as the Spider Witch.
* FateWorseThanDeath: Her minions, not herself. It is heavily implied the spider minions are the souls of the men she murdered. Now dead, they are forced to serve her as spiders for all time.
* {{Foreshadowing}}: Her presence in the Sedgewick Hotel was hinted at early in the game. On one of the doors in the first level, you can see a ghost spider with the PKE meter. This door leads to the Spider Witch's old suite.
* GiantSpider: After her death, if she was ever even alive, she was turned into a giant spider woman.
* HealingFactor: While the Busters battle her, she can feed off...something to heal herself from damage. Depending on whether you can find her or not will define whether your battle with her will be fast or long.
* HumanoidAbomination: Besides her spider humanoid form, she was this in life. She fashioned her suite to her bizarre tastes. Furniture was all heaped in a corner chewed up, and she painted blood everywhere in the room. Let's not forget her hanging men collection.
* KnifeNut: She has some major BloodLust and enjoys carrying a knife when taking her "husbands" to her suite. You put the picture together.
* MixAndMatchCritters: In her ghost form, she became [[SpiderPeople part woman and part spider]].
* NoNameGiven: Despite the crimes she committed, the authorities never discovered her name, not even a false one.
* ProfessionalKiller: She worked for Shandor and is implied to have killed many men for Shandor's cult. Not really paid to do this, she just really likes to kill.
* RightHandHottie: She loyally serves Ivo Shandor as a guardian over the Sedgewick's mandala node in her death. In life, she had killed many men for a reason only she and Shandor know.
* SpidersAreScary: That's basically her levels entire theme.
* SpiderPeople
* UrbanLegend: She is this to the Sedgewick Hotel staff. They were terrified enough to keep her room locked...till it was opened for remodeling.
* TheVamp: She would seduce unknowing men so she could paint her room with their blood and possibly make them her eternal minions.

!!Azetlor AKA Edmund Hoover

* AscendToAHigherPlaneOfExistence: Before being executed, he told everyone that he was going to be reborn as Azetlor. [[OhCrap He was]].
* BadassBookworm: He ''loves'' books a lot. To the point he will kill for them. Though we don't know what he looked like in life, Ray suggested that he was a sniveling little bookworm.
* TheDogBitesBack: [[spoiler:He really shouldn't have killed Eleanor Twitty.]]
* CoDragons: He shares this with the Chairman.
* TheCollector: He collects the dead bodies of his victims, much like the Spider Witch. He also collects books.
* EldritchAbomination: He became a mass of Black Slime and broken furniture with a helmet after his death.
* IHaveManyNames: Edmund Hoover, Edmund Hoover the Collector, The Library Serial Killer, Azetlor, Keeper of Knowledge, Azetlor the Finder, Azetlor the Collector, Azetlor the Returner, Azetlor the Lost, Azetlor the Destroyer, and Azetlor the Bookworm. Basically the opposite of the [[NoNameGiven Spider Witch]].
* KickTheDog: [[spoiler:When he seduced Eleanor Twitty to get at her library's rare book collection. When she figured out what he was doing, he murdered her and damned her to an eternity in her beloved library.]]
* MeaningfulRename: He changed his name from Edmund Hoover to Azetlor. Azetlor was a Sumerian demigod that ruled over the lost. Originally he collected all that was lost, but grew greedy and began to collect what he shouldn't. Much like what Hoover did with the librarians he killed and his books.
* MyDeathIsJustTheBeginning: After his death, he became a mandala guardian of the Library to continue serving his master Shandor.
* SerialKiller: He was known as the "Library Serial Killer."
* WouldHitAGirl: [[spoiler:Murdered his girlfriend Eleanor Twitty, and many other women after her.]]

[[folder: Others]]

!!Dana Barrett (Creator/SigourneyWeaver)


-->''"Well, that's just great. Either I have a monster in my kitchen or I'm completely crazy."''

* ActionMom: She becomes one in the second movie.
* DefrostingIceQueen: As the first film progresses.
* DemonicPossession: Victim of this for half of the first film.
* LoveInterest: To Peter.
* MamaBear: She doesn't need a Proton Pack to be a ActionMom!
* NeutralFemale: Averted. She tries to keep away from the trouble so as not to get in the guy's way, but when it comes to her, she fights back.
* OneOfTheGuys: Even after she breaks up with Peter, she still gets along with all the Ghostbusters and vice versa.
* TheReliableOne: You can always count on her. One of the reasons she and Peter broke-up, temporarily.
* SingleWomanSeeksGoodMan: Had a ''lot'' of trouble finding one for a while.
* StatuesqueStunner
* WhatExactlyIsHisJob: Goes from being an orchestral performer in the first movie to retouching paintings in the second, with no explanation for the jump.

!!Louis Tully (Creator/RickMoranis)


-->''"Who does your taxes?"''

* ButtMonkey: Especially in the first movie. Although, since he ''does'' get to nail both [[spoiler:Dana (while [[DemonicPossession possessed]])]] and Janine, he's either the ''unluckiest'' or ''luckiest'' character.
* DemonicPossession: [[spoiler:[[CallBack He was once turned into a dog and the Busters helped him]].]]
* {{Determinator}}: Louis may not be as tough as many of the characters, but he managed to outrun a terror dog before it cornered him. To add bonus points, he survived jumping over a wall near the Tavern on the Green, with out any injury. JamesRolfe pointed out during a tour of the Ghostbusters locations, that said wall would risk breaking your legs due to it's long drop.
* DoggedNiceGuy: To Dana and later Janine.
* FatAndSkinny: The Skinny to Slimer's Fat.
* FriendToAllChildren: Louis despite his awkwardness is good with kids, managing to get Oscar to sleep. The second Oscar gets kidnapped, he goes to get the Ghostbusters out of the Asylum and [[TookALevelInBadass then suits up himself.]] Though the latter of which might have been due to a confidence boost after having sex with Janine.
* NerdGlasses: To rival Egon's.
* NonActionGuy: At first. He picks up a proton pack in the second movie.
* NonPoweredCostumedHero: While not being an expert fighter, he put on the Ghostbuster uniform and did his part to help save the day in the second movie.
* OddFriendship: Once he gets over being scared of Slimer, the pair seem to get along pretty well.
* [[OmnidisciplinaryScientist Omnidisciplinary Lawyer]]: Averted and lampshaded in the second film. He specifically warns the main quartet that he doesn't know criminal law. Sure enough, he botches the defense and the judge rules against them. It's only the timely appearance of ghosts (thereby proving to the disbelieving judge [[CassandraTruth that ghosts are real]]) that get the Ghostbusters off the hook. To his credit, Tully does help play legal hardball at that moment to force the judge to rescind the restraining order.
* SixthRanger: He becomes something like this in the second movie.
* StalkerWithACrush: He comes off this way in the first film, what with apparently sitting just inside his apartment door all day long so he won't miss Dana walking down the hall.
* SubmissiveBadass: In the second film.
* TookALevelInBadass: Double subverted. He does strap on ghostbusting equipment to help the team out in the second movie, but he's still far from {{Badass}}... at first.
--> I'm right here with you, guys!

!!Janosz Poha (Peter [=MacNicol=])

* BrainwashedAndCrazy
* CreepyCrossdresser: [[spoiler:When he dressed up like a demon nanny to kidnap Oscar [[{{Beat}} ...]] you'd have to be there.]]
* DemonicPossession: Vigo forces his will upon Janosz, making him do his bidding.
* {{Deprogram}}: [[spoiler:Thanks to the ''good'' version of the mood slime, he's freed from Vigo's influence. And he and Ray are turned into a pair of [[LoveFreak Love Freaks]].]]
* FunnyForeigner: Of some kind...
* GlowingEyesOfDoom: Chillingly realized when he visits Dana during the blackout scene. After a somewhat unnerving discussion, Dana tells him to leave. Once he is now alone in the dark, his eyes suddenly start to glow like flashlights in the dark hallway. A lot more disturbing than it sounds.
* HarmlessVillain: [[spoiler:He becomes a NotSoHarmlessVillain after kidnapping Oscar.]]
* HeelFaceTurn: [[spoiler:Thanks to the mood slime.]]
* HopelessSuitor: Where Dana is concerned.
* LoveMakesYouEvil: Well, DemonicPossession, but still counts.
* [[LoveRedeems Mood-Slime Redeems]]
* TheRenfield: Peter [=MacNicol=] played the Renfield here before playing ''the'' Renfield in ''Film/DraculaDeadAndLovingIt''.
* {{Ruritania}} / WhatTheHellIsThatAccent: Just where on Earth ''is'' he supposed to be from?
-->'''Venkman''': You'll never get a green-card with that attitude, pal.
** "The Upper Vest Side," of course.
*** According to the comics he's from Moldavia.
* VampireVords

!!Ilyssa Selwyn (Alyssa Milano)

[[caption-width-right:241:Just watched a giant marshmellow man blow up, no biggy.]]
* AllThereInTheManual: Most of her life before the game.
* ConvenientlyAnOrphan: Her parents died in a cave-in when she was 15.
* DistressedDamsel: She gets kidnapped twice in the game, and both times has to be saved by the Ghostbusters.
* DemonicPossession: In the start of the game, she is possessed and brought to the Sedgewick Hotel 12th floor. Later, she is possessed momentarily while she's at the museum.
* HappilyAdopted: Her adoptive parents used to bring her with them everywhere...till, you know, they died.
* [[IdenticalGrandson Identical Great-Granddaughter]]: Ilyssa looks just like her great-grandmother, [[spoiler:Ivo Shandor's mother]].
* InformedAttribute: Her fact sheets says Ilyssa enjoys traveling, modern painting, French New Wave cinema, is fluent in six languages (two of which haven't been spoken in over 4000 years), plays violin proficiently and is learning the cello. Well, she's quite well-rounded, ain't she?
* InTheBlood: Sorta. [[spoiler:Ilyssa doesn't realize she's the granddaughter of Ivo Shandor for most of the game, but she has a strange fascination with Gozerian mythology. Shandor was a big believer in Gozer back in his living days.]]
* {{Irony}}: She hates abrasive or pushy personalities. [[{{Jerkass}} Guess who she falls in love with]]?
* [[LikeFatherLikeSon Like Father, Like Daughter]]: She ended up getting into anthropology just like her parents.
* LoveInterest: Replaces Dana Barrett as this in the game.
* LukeIAmYourFather: [[spoiler:Ilyssa finds out she is a direct descendant of Ivo Shandor. How is this revealed to her? He tries to sacrifice her, of course.]]
* ParentalAbandonment: Twice! Both her biological ''and'' her adopted parents died when she was young. [[AngstWhatAngst She doesn't seem broken up about this]].
* {{Tsundere}}: Type B, she seems to be nice normally, unless she's around Venkman. [[{{Jerkass}} Can you really blame her, though?]]
