->'''In most stories, the hero faces his foes without fear. [[WellThisIsNotThatTrope This is not one of those stories]].'''

''Luigi's Mansion'' is a 2001 video game produced by Creator/{{Nintendo}} and released as a launch title for the NintendoGameCube. Though set in [[TheVerse the universe]] of ''Franchise/SuperMarioBros'', the game is unusual in that it is not a platformer, but a third-person adventure game (it could even be considered a sort of ''Mario''-themed comic parody of the survival-horror genre, right down to a spoof of the ''VideoGame/ResidentEvil'' loading animation) and in that the character of Mario plays the role of [[DistressedDude brother in distress]] and is not a player character at all, appearing only briefly around the middle and at the end of the game.

The plot follows Mario's brother, [[TheLancer Luigi]], who won a mansion in a dark, spooky forest from a mail-in contest he didn't even enter. Once he finds it, he gets burdened with some grim news: The mansion is not only infested with evil ghosts, but their leader has trapped Mario inside a painting and is waiting until midnight to take possession of him forever, using Mario as a new body for his disembodied self.

With the help of a kindly old [[WhoYouGonnaCall ghost-buster]] / MadScientist named Professor Elvin Gadd, Luigi straps on his trusty Poltergust 3000, a vacuum cleaner that can trap ghosts as well as money, items, and some minor props, and sets forth to rid the mansion of its ghastly inhabitants and rescue his brother from the spooky mansion.

Basically, the aim of the game is to capture all ghosts in the mansion while finding as much cash as possible, which is littered around the mansion in the form of gold coins, bills, gold bars and jewels. At the end of the game, the amount of money you were able to obtain is tallied up, and Luigi uses it to buy a house in accord to how much he has, from a truly regal estate if you did really well to a decrepit little shack if you really suck at the game or a tent if you go out of your way to avoid gathering money.

Despite not having a sequel for many years, the game has been represented in other games such as ''VideoGame/MarioKart'', ''VideoGame/SuperSmashBros'', and ''VideoGame/NintendoLand'', showing that Nintendo hasn't forgotten the game. Eventually, in 2013, a sequel finally arrived via the Nintendo3DS: ''VideoGame/LuigisMansionDarkMoon''. An Arcade spinoff developed by Sega, simply called ''Luigi's Mansion Arcade'' was released in Japan in 2015.
----
!!Tropes:
* AllLoveIsUnrequited: Shivers is deeply in love with Melody, but apparently she "won't even give him the time of day" (possibly because of their age difference of almost 50 years).
* AllThatGlitters: The Red Diamonds; like the Gold Diamonds (which actually ''are'' extremely valuable), there are only two in the game, but each one is only worth as much as a single gold coin (amusingly, one of these two red diamonds acts as [[spoiler:the jewel in King Boo's CoolCrown, and you get this automatically when you defeat him at the end of the game]]).
* AnIcePerson:
** Sir Weston, the second-to-last Portrait Ghost, is a Portrait Ghost trapped in a cube of ice, who, when awakened, will launch icicle waves at Luigi.
** Some ghost mooks are frozen and must be defeated through the direct application of flame.
* AmazingTechnicolorBattlefield: The trippy boss rooms, including the infernal one for the final boss.
* AndIMustScream:
** Reading Sue Pea's description states "What was supposed to be a short nap turned into eternal sleep for the young Sue Pea." This also hits terrifying levels when you realize the AdultFear of something happening to a child after they fall asleep.
** Mario being trapped inside the painting possibly ''for all eternity.'' Of course, you could say the same thing about what happens the Portrait Ghosts, but at least one of them (Madame Clairvoya) doesn't seem to mind that at all, actually ''asking'' Luigi to put her there.
* ArtInitiatesLife: Vincent Van Gore brings the ghost mooks to "life" from portraits he paints, which you find out for yourself when you reach him toward the end of the game.
* AsteroidsMonster: Boolossus, who is the third boss, is an amalgamation of ''fifteen Boos''. When punctured, not only will he split up into his components, he'll recombine after a few seconds.
* BadassInDistress: Mario.
* BadGuysPlayPool: Slim Bankshot is found in a billiard room. To catch him, one has to fire his own billiard balls back at him.
* BigBoosHaunt: The mansion (that is to say, the entire game).
* BigEater: Mr. Luggs. In fact, he died due to overeating, but [[{{Determinator}} that didn't stop him]]...
* BigSleep: Sue Pea is explictly stated to have been a HeavySleeper in life, so much so that she died in her sleep. Even as an undead, she continues to sleep a lot.
* BeatThemAtTheirOwnGame: A villainous example: [[spoiler:Final boss King Boo's Bowser mecha has an attack that uses a vacuum of its own to swallow Luigi if he gets too close]].
* BlackoutBasement: Normally, the lights come on once every ghost in any given room has either been caught or otherwise defeated. However, the beginning of the fourth area of the game includes a mansion-wide blackout, during which no amount of ghost-catching will bring the lights back. To fix the problem, you must work your way back from the third-floor balcony to the basement to turn on a backup generator. [[spoiler:Or you can take the mirror to the Foyer.]]
* BlindedByTheLight: Luigi has to stun ghosts with his flashlight before capturing them. The sequel makes this even more effective with a chargeable strobe function.
* BlobMonster: Bogmire, boss #2.
* BonusBoss: Quite a few of the Portrait Ghosts (including Slim Bankshot, Mr. Luggs, Jarvis, and a few others) are optional, and you can complete the game without bothering them at all. However, beating them often gains you some valuable treasure. Most Portrait Ghosts are required battles, though.
* BonusFeatureFailure: What do you unlock for beating the game? A Hidden Mansion! What happens in said mansion? Well, the ghosts and Poltergust are stronger... and that's it. Averted in the PAL versions of the game, which featured more changes. It's impossible to get the best rank without playing the Hidden Mansion, for one thing, because the normal mansion doesn't have enough money. It also mirrors the entire game, ramps up the difficulty (ghosts deal more damage and there are fewer hearts), changes some of the puzzles a little, switches the money and gem locations all over the house, and retools some of the boss encounters, varying from mild variations in their attack pattern to the entirely different Boolosus fight, which has the whole floor covered on ice and Luigi has to ride the Poltergust to "snowboard" across the arena. The ghost-ridden rooms are also a lot darker which are quite difficult to explore unless you use your flashlight, or have memorized the positions of the furniture from previous game-play experience.
* BossArenaIdiocy: The stage of Boolossus, the third boss, has two unicorn statues at either end, which can be used to pop him. (Then again, this is probably deliberate -- the smaller Boos are ''fast'', and get faster the less of them there are.)
* BossCorridor: These are at the end of first area, the third area, and at the end of the game, and the Boos will stop you reaching the end of the last two corridors and send you back to the front door of the mansion if you haven't caught enough Boos (you need 20 for the Area 3 boss, and 40 for the final boss; the Boos have not yet appeared by the time you reach the Area 1 boss, as they are unleashed shortly into Area 2.)
* {{Bowdlerise}}: Originally the Safari Room in Area 3 was apparently supposed to contain a "hunter" Portrait Ghost, who wielded a gun and stated that he wanted to mount Luigi's head on the wall, but the idea was scrapped to keep the game E rated, so the room only contains standard ghosts (the room is still dangerous, as it's the first room in the game where Luigi meets the smashing ghosts that pound the floor and cause shockwaves; trash can ghosts are also in this room).
* BreakTheCutie: The major plot point of the game. Luigi was just going to visit the mansion with his brother, but was actually a set-up by King Boo to get rid of Mario forever. With the help of Elvin Gadd, Luigi has to save Mario equipped with a ghost-sucking vacuum cleaner, while dealing with ghosts he's scared to wits over all over the mansion. [[spoiler: [[CrowningMomentOfHeartwarming Which makes the ending all the more heartwarming.]]]]
* BreathWeapon: Mr. Luggs' fireballs.
* CameraScrew: Part of what makes Boolossus, the third boss, so difficult is that once it's down to just a few Boos, the camera will inexplicably move in much closer to Luigi, making it very difficult to see incoming Boos before they swoop in to attack.
* CharacterDevelopment: What you would expect from his own game. This was the first game which confirmed his cowardice as a definable trait of his.
* CharacterizationMarchesOn: This was one of the first games to depict Luigi as being phobic, and his fear has since [[DivergentCharacterEvolution become his most distinguishing trait]]. This was first touched upon in VideoGame/PaperMario if you read Luigi's diary after Toad Town has been visited by ghosts. Luigi ''really'' does not like ghosts.
* ChestMonster:
** Jarvis, who hides in the various jars in his room.
** Some mook-level ghosts work like this too, jumping out at you when you investigate nooks and crannies for extra loot, with particularly nasty examples in the [[AnIcePerson Hidden]] Room and Sealed Room (the latter unleashes FOUR ghosts at once when you open the chest in front of the mirror). Subverted with the [[ColorCodedForYourConvenience blue]] [[MetalSlime ones]] (Speedy Spirits) in that they still [[MoneySpider give up a ton of valuable shinies]] when you defeat them, though.
* ColorCodedForYourConvenience: Chests. Blue ones contain keys; green ones are full of money; gold ones are boss loot and have keys to new zones in them; the ones containing the [[ElementalPowers medals]] are red, blue, and white respectively; and the ones containing Mario's items and those used as scenery in the secret rooms are all red.
* ConsoleCameo: The [[GameBoyColor Game Boy Horror]], which is a means of communication between Luigi and E. Gadd and also provides a map of the mansion.
* CordonBleughChef: Gadd ''might'' qualify. After Luigi defeats Boolossus, the third boss, he offers to make dinner, and make his "old family recipe", which is "pickled dandelions with barnacles in a diesel marinade". (Of course, we never see it or Luigi's reaction... Who knows? It might be better than it sounds.)
* CowardlyLion: Luigi, given that he still saves the day despite his obvious fear.
* CreepyBasement: The final area, which stays dark even after you defeated the final Portrait Ghost.
* CreepyCemetery: The Boneyard, as well as the Graveyard/Cemetery, where the Area 2 boss lives.
* CreepyChild: Chauncey, the twins, and Sue Pea, a girl on the third floor.
* CreepyTwins: Henry and Orville. If they [[SoreLoser lose]] in Hide-N-Seek, they will try to kill you, and you can't complete the game without dealing with them (they have one of Mario's possessions, which you need to take to Madame Clairvoya).
* CriticalAnnoyance: As Luigi's HP gets lower, his humming will become more rattled and nervous, and he makes gasping noises when opening doors.
* DarkerAndEdgier: For all its quirkiness and humor, the game is still somewhat darker than main ''Mario'' titles. It doesn't help that some of the Portrait Ghosts' deaths can be TruthInTelevision.
* ADayInTheLimelight: Luigi steals the spotlight from Mario here.
* DeadpanSnarker: Luigi, commenting on things he sees in the mansion. Who would have thought he was quite the art critic and clean freak?
* DeathByGluttony: Mr. Luggs, who died by overeating. He's just as much of a BigEater in the afterlife, though now all the food he eats goes right through him.
* DefangedHorrors: A LighterAndSofter take on the SurvivalHorror genre.
* DemBones: The skeleton ghosts, who only appear in three rooms (the Boneyard, where one is woken up when the ghost dog barks enough, the Graveyard behind this, where they guard the Area 2 boss and rise when you tap one of the graves in the middle, and the Telephone Room, where they are in chests; the skeletons in the first two of these rooms must be defeated in order to proceed through the game).
* {{Determinator}}: Even if it means his own death on his way, Luigi will do anything he can to save his brother, whom he looks up to more than anyone else, rather than resent him for usually taking the spotlight.
* DetonationMoon: In order to obtain [[StarShapedCoupon Mario's Star]], Luigi must create a path of stardust by using meteor-like projectile ghosts to destroy the moon. It's an illusion, though.
* DistressedDude: Mario.
* DoesThisRemindYouOfAnything: The entire scenario of the first ghosts you defeat in the game. First, you suck up Neville, then his wife Lydia next door. After you've done this, you can hear their baby crying in another room in the same hallway. The whole thing sounds very much like a SerialKiller coming in to slaughter a whole family, ending with the child who's completely oblivious to it. (Neville and Lydia are actually the most docile of the portrait ghosts, keeping entirely to themselves until you disturb them. If you feel guilty, well, Chauncey's a RealityWarper with a NightmareFace and the first boss of the game, which throws a curve ball at you as far as dealing with ghosts go).
* TheDragon: [[ArtInitiatesLife Vincent Van Gore]], technically. He creates all the minor ghosts you encounter in the mansion, is the final regular Portrait Ghost in the game, and is the one keeping the key leading to [[spoiler:[[BigBad King Boo, the FinalBoss]].]]
** In-story, it seems to be [[spoiler: Boolossus, the third boss of the game,]] because the BigBad attacked E. Gadd in order to free him (and freed the other Portrait Ghosts mostly to add injury to insult).
* DualBoss: Henry and Orville (considering their vehicles, they're also an homage to Henry Ford and Orville Wright).
* DummiedOut: A lot of things were changed or dropped from [[WhatCouldHaveBeen the early version]] compared to the final product, including but [[http://tcrf.net/Luigi%27s_Mansion but not limited to]]:
** How many promotions allude to the fact that [[TimedMission Luigi was timed]] and had to rescue Mario within the night, or else [[spoiler:Mario will be lost and Luigi will be possessed by a ghost as he leaves the mansion]].[[note]]However, the timer originally seen on the Game Boy Horror, often cited as evidence of this, could have just been there in the E3 demo to keep people from hogging the game.[[/note]]
** How images of Luigi were to follow the final new mansion to show his reaction to it (one with two peace signs while grinning, another with one, and a third with him sulking while holding a flower). Or possibly they were meant to react more to the above concept.
** The Game Boy Horror only taking the lower corner of the screen over the entire screen.
** A ghost who can harm Luigi to temporarily make his max HP 50 in addition to other damage.
** The Poltergust 3000 would burst into flames if left running for too long.
** An unused piano version of Totaka's Song, suggesting it was to be played by Melody Pianissima.
** An unused model for Mario stretched to fit Luigi's size suggests that there was at least some testing done for a co-op multiplayer, with being a placeholder for a proper Mario with the Poltergust model.
* DynamicLoading: If the action freezes right before you open a door, that means the area hasn't finished loading yet.
* EarnYourBadEnding: The worst "mansion" you can get is a mere tent, but it is considered even harder to get than the best mansion, as you have to go out of your way to avoid collecting any kind of money other than coins (which are the only kind of money you can drop), and even then, not too many of those.
* EasterEgg: Stand next to the Well and listen closely. It may be referencing the time-limit that was once in the game.
-->[[spoiler:'''Mario''': Hey, Luigi! What's the holdup?]]
* ElementalRockPaperScissors: The elemental ghosts, when sucked up, allow the Poltergust 3000 to expel fire, water, and ice. These elements factor into gameplay and can affect things around the mansion. There are also ghosts who have their heart surrounded by a certain element and can only be sucked up after being exposed to the element they are weak to. Water beats fire, ice beats water, and fire beats ice.
* EndGameResultsScreen: The state of the mansion at the very end depends on the amount of gold you obtained, and you're given both a letter grade and an appropriately happy Luigi. The mansions range from a beautiful manor for an A to a ''tent'' for an H, with a depressed Luigi and somewhat creepy music.
* EnfanteTerrible: Chauncey, Henry and Orville, and Sue Pea.
* ExtremelyDustyHome: Walking around and opening drawers seems to disperse a lot of dust. Examining furniture with the Game Boy Horror occasionally makes Luigi note how dusty the mansion is. The cellar is so dusty that it [[InsurmountableWaistHighFence actually blocks Luigi]] unless he vacuums it up.
* ExtremelyShortTimespan: The game only covers a single night, around 8 hours at best. Considering that it was originally a TimedMission...
* EyeBeams: Used by Nana.
* FanDisservice: One of the Portrait Ghosts is first seen in the shower, and her shadow is a beautiful shapely (and nude) woman. When you pull back the curtain to reveal her, however, she looks like [[CasperTheFriendlyGhost Fatso's]] twin sister.
* FightingAShadow: Bogmire, the second boss, projects shadows of himself. Luigi has to capture these shadows and encase the genuine article in them.
* FMinusMinus: You can get a grade for your performance as low as an H, but this requires effort.
* FlunkyBoss: All the bosses except [[spoiler:King Boo and Costume Bowser]] are like this. Chauncey fights with the help of giant bouncing beach balls and haunted rocking-horses, Bogmire casts several shadows over the room (all of which act independently from him and one another), Boolossus gets "popped" like a balloon on the horn of a unicorn statue and becomes several smaller versions of himself, and Vincent Van Gore makes the figures in his paintings come to life and attack you.
* FortuneTeller: Madame Clairvoya will tell you key information if Luigi can bring her some of Mario's things.
* GadgeteerGenius: Professor Elvin Gadd built the machine to capture ghosts, turn them back into portraits, and the Game Boy Horror scanning device.
* GenreSavvy: King Boo. Also, Elvin Gadd.
* GameplayAndStorySegregation: The GameBoy Horror states that Chauncey was born a ghost, yet the Nursery contains photographs of him when he was alive.
** Lydia, as a ghost, has very light blonde hair, yet photographs of her when she was alive show her with very dark brown, almost black hair.
* GiantMook: Boolossus, the Area 3 boss.
* GiantSpaceFleaFromNowhere: Just what ''is'', or ''was'', Jarvis? Besides Spooky, he's the only non-humanoid, non-boss Portrait Ghost. It's unclear why he looks so different from all the others.
* GooGooGodlike: Chauncey is Neville and Lydia's third son, who for some reason unbeknownst to Lydia is more terrifying than the twins. It's implied his powers as a RealityWarper might have something to do with the fact that unlike all the the other spectres in the mansion he was conceived and born as a ghost to begin with.
* GottaCatchEmAll: The ghosts and the Boos. Getting the best ending also involves collecting as much money as possible (and ironically, getting so little of it is a challenge, having to "avoid" the money). If you get all fifty Boos (excluding King Boo), then you get [[spoiler:one of the only two golden diamonds, the most expensive treasure you can get]].
* GuideDangIt: The game dosen't tell you you have to skip the Boo save after getting the final Boo. This is because E. Gadd calls you right before you collect the gold diamond, making the game think you didn't collect it at all.
* HauntedHouse: The titular mansion.
* HauntedHouseHistorian: Professor: E. Gadd.
* HijackedByGanon: [[spoiler:Subverted. At first, you seem to face Bowser once again as the final boss, but after blowing his head off, it is [[MonsterSuit revealed to be a costume controlled by King Boo.]]]]
* HollerButton: Pressing the A button when not near an interactive object makes Luigi shout "Mario!" The way he says it also depends on how much health he has left. If Luigi's at full health, he'll sound confident. If he's low on health, he'll be a stammering mess.
* HumanPopsicle: Sir Weston, the semifinal Portrait Ghost and one of the most difficult ones to catch in one shot, died in ice, and during battle, he encases himself in ice.
* HumongousMecha: [[spoiler:King Boo's Bowser Costume]]. It doesn't need to "look" robotic to qualify as such. The fact that it's lifelike in appearance -- especially for a giant costume -- shows how much further ahead of the rest it is. That, and it emphasizes [[spoiler:King Boo's trickery]].
* HurricaneOfPuns: Most of the Boos' names. There are a total of ''[[http://www.mariowiki.com/List_of_Boos_in_Luigi%27s_Mansion thirty-six]]'' Boo puns, each cheesier than the last. One is even named [[spoiler:Booigi]]! (There's actually a practical reason for this: It helps you keep track of them. You need to catch a certain amount to fight Boolossus and even more to fight King Boo, and [[spoiler:catching ''all'' of them gains you a Golden Diamond, the most valuable treasure in the game.]])
* IdiotBall: King Boo {{lampshade}}s this:
--> "Anyway, who would actually believe that mansions get given away in contests? Talk about stupid! What do they feed you Mario Bros. anyway? Gullible soup?"
* InfantImmortality: Double subverted. You don't ''see'' any kids dying, but some of the Portrait Ghosts are kids.
* IWasQuiteALooker:
** Miss Petunia was a model in life, but has really let herself go since then.
** Various portraits around the house depict what some of the Portrait Ghosts looked like while they were still alive.
* TheJeeves: Shivers, who roams the house in search of his master's will.
* JumpScare: If you vacuum the poster in the 2nd floor Washroom or the screen in the Projection Room for long enough, it will suddenly snap back, changing into an image of a Boo over the words "get out of here" and making Luigi fall back and lose 5 HP. This can be quite alarming, especially on the big projector screen.
* KillItWithFire: One of the uses for the Fire Element is to burn ghosts.
* KillItWithIce: One of the uses for the Ice Element is to freeze ghosts solid. It also slows down skittish Boos.
* KillItWithWater: One of the uses for the Water Element is to soak down the Bomb Ghosts as well as regular ghosts (the Bomb Ghosts are otherwise invincible; sucking them up simply has them exploding in your vacuum and damaging you anyway).
* LeftTheBackgroundMusicOn: Implied; Luigi sings/hums/whistles along with it constantly.
* LighterAndSofter: Of Survival Horror games in general.
* LivingShadow: Bogmire, the Area 2 boss, creates shadow duplicates of himself.
* LovableCoward: Luigi.
* MadScientist: Professor Elvin Gadd. (His name is a pun: Professor E. Gadd.)
* MadeOfEvil: Bogmire, the boss of Area 2, although in this case, it's more like "Made of Fear", and he actually might be sort of a sympathetic figure: His biography claims, "A product of the mansion's fear and despair. He's not sure who to fear or what to despair these days."
* TheManBehindTheMan: Many hints throughout the game seem to indicate that [[spoiler:[[BigBad Bowser]], not King Boo,]] is the one who trapped Mario. [[spoiler:This turns out to be a subversion during the final battle, however, when Luigi blows "Bowser's" head off... and he is revealed to be just a MonsterSuit. Controlled by King Boo.]]
* MayDecemberRomance: According to his heart dialogue, Shivers (who is 72) is absolutely besotted with Melody (who is only 26). It's entirely one-sided, though.
* MetalSlime: Speedy Blue Spirits and the Golden Mice. You have only one chance to catch each individual one, and they will fight you bitterly if you manage to get them within range of your vacuum (except for the Gold Mouse ghosts; those are wimps). If you do catch them, though, they release absurd amounts of riches for you to collect.
* MoneySpider: Portrait ghosts release pearls of various worth when they're caught, but it depends on how much you struggled to pull them in. If you can trap them in one long vacuum-suck, they release enormous pearls. If they keep escaping your pull, you'll be limited to the smallest pearls (the size of pearls you get also determines the type of painting they turn into at the end of the area they are in). This trope also applies to the Speedy Blue Spirits and the Golden Mice.
* MookMaker: Almost every non-portrait ghost is created by a single boss, Vincent Van Gore, who is unsurprisingly the last main Portrait Ghost encountered in the mansion before the FinalBoss.
** He also qualifies as such when Luigi actually fights him, sending waves of Mooks after the hero. Once all the Mooks are defeated, Van Gore himself is actually a pushover. (In fact, he kind of gives up.)
* MultipleEndings: At the end of the game, Professor E. Gadd builds Luigi a new house. Which house you get depends on how much treasure you collected in the game from a sprawling mansion all the way down to a measly tent. (Getting the worst option is actually harder than getting the best; you'd likely have to pick up no treasure at all except the stuff that you automatically gain.)
** The D-rating appears to be the canon ending, because that appears to be Luigi's house in [[VideoGame/LuigisMansionDarkMoon the sequel]], judging by the picture above his couch. However, the Rank A mansion appeared in Luigi's Circuit from MarioKartDoubleDash.
* MusicalNod:
** The first eight notes of the music that plays when Luigi talks to Toad are the same notes that played when he was talked to in VideoGame/SuperMario64.
** The song that the instruments play in the Conservatory is the {{VideoGame/Super Mario Bros|1}}. theme. Also in the Conservatory, Melody will play either the Athletic theme from VideoGame/SuperMarioBros3, the starting music from VideoGame/MarioBros, or the underwater theme from {{VideoGame/Super Mario Bros|1}}..
* NeatFreak: Luigi is implied to be one to some extent in his commentary. Examining furniture with the Game Boy Horror makes him complain about moth holes in furniture, how the place would never pass a white glove test, and how he regrets to have not enough time to tidy up a desk. Fittingly, his weapon of choice in this game is a [[WeaponsThatSuck modified vacuum cleaner]].
* NightmareFace: Chauncey, the boss of Area 1, is pretty cute (for a giant ghostly baby). But when he cries...
* NoCelebritiesWereHarmed: Biff Atlas is, of course, [[TheAhnold Arnold Schwarzenegger]] in appearance and vocal mannerisms.
* {{Onomatopoeia}}: King Boo has one for vacuuming during his monologue.
* OurGhostsAreDifferent: Most of the Portrait Ghosts are explicitly stated to be humans who died (the exception being Chauncey, who was born a ghost) while {{Mook}}-level ghosts are more ugly and/or monster-like in appearance and are in fact the living (so to speak) paintings of the portrait ghost Vincent Van Gore, the Dragon and final major Portrait Ghost fought in the game.
* PaperMaster: Melody Pianissima attacks with sheet music.
* PeekABogeyman: The dangling ghosts just want to scare Luigi. They jump out at you noisily in the dark, but cause no damage. (Except for the purple ones, which carry cartoon bombs.)
* PunnyName:
** Prof. E. Gadd = Egad.
** In the Japanese version, his name is "Prof. Oyama." ''Oya ma'' is a Japanese exclamation that roughly translates to "Egad!"
** In the Japanese version, the "Poltergust 3000" (itself a pun on "poltergeist") is known as the "Obacuum", a combination of "obake" (a word referring to a ghost, etc), and "vacuum".
** Many of the ghosts' names, Boos or not.
* RecurringRiff: The ''Luigi's Mansion'' theme.
* RefrigeratorAmbush: An ice ghost is hiding in the fridge. Plus it knocks you over and hurts you if you open it by hand instead of sucking it open (its one of two pieces of furniture that can do that the other being a shed with a Toad in the courtyard.)
* RegionalBonus: ''The Hidden Mansion'' becomes a mirror version of the regular mansion and bosses have noticeable changes in how they are fought. Unfortunately, other regions get ''The Hidden Mansion'' detailed in BonusFeatureFailure.
* {{Retraux}}: The appropriately named [[http://www.youtube.com/watch?v=0_FquzflYYU Game Boy Horror theme]].
* SayMyName: "MAAARIOOOO!!!"
* SceneryPorn: It WAS a Gamecube launch title after all...
* SelfImposedChallenge: Getting every last penny in the mansion and getting as ''little'' money as possible.
* SexySilhouette: When Luigi enters the bathroom, he at first sees the silhouette of an attractive woman behind the shower curtain. [[spoiler:Subverted when the curtains are pulled back and we see that it's [[FanDisservice actually]] [[{{Gonk}} Miss Petunia]]]].
* ShmuckBait: Lots. A trail of coins leading to a door that is in fact fake and will squish Luigi against the wall if he opens it, a red button that has a sign hanging under it saying "Don't push!" [[spoiler:[[StupidityIsTheOnlyOption But you have to]], to unleash the Boos]], and so on.
* ShoutOut:
** King Boo almost directly quotes [[StarWars Jabba the Hutt]] at one point.
** The cover is reminiscent and a parody of ''Film/HomeAlone''.
** Luigi parodies ''The Scream'' by Edvard Munch in most ads.
** There are several references to Ghostbusters, such as:
*** The Garbage Can Ghosts being based on Slimer.
*** The final battle being on the roof.
*** The first human ghost being located in the library.
*** The Poltergust is a complete spoof of a proton pack, both worn on the back with hoses, but one is a vacuum. The capturing of the ghosts is reminiscent of the Slimer's capture. The Poltergust looks like a proton pack, but works like a ghost trap, and the flashlight serves the purpose (stunning) of the proton pack.
** The name of The Floating Whirlindas. a pair of dancing ballroom ghosts, comes from a famous circus stunt group, The Flying Wallendas, and they bear an uncanny resemblance to [[Series/ILoveLucy Lucy and Desi]].
* SkippableBoss: Five Portrait Ghosts are optional, can be captured at any time after their rooms are unlocked, and can be ignored entirely if you don't care about OneHundredPercentCompletion; Mr. Luggs, Biff Atlas, Slim Bankshot, Sue Pea, and Jarvis, in that order. Rather than a key to unlock another room, each of these ghosts instead yields a treasure chest filled with money (including a rare diamond) when defeated.
* TheSoCalledCoward: Luigi endures the spiteful ghosts, hostile portrait ghosts, and the ever so gloaty Boos, which try to hinder him on his way to Mario.
* SoreLoser: Henry and Orville ask Luigi to play hide and seek with them, while Jarvis challenges him to a game that's sort of like "whac-a-mole". In both cases, if Luigi wins, the ghosts get angry and attack him. (However, this is the only way he can capture them, something which is required to proceed in the case of the twins; they hold one of the items you need to bring to Clairvoya and finish Area 3.)
* SuddenlyVoiced: This is one of the few games where Mario has actual spoken lines of dialog, as evident in the letters and if you listen to him at the bottom of the well. (He doesn't speak when encountered before [[spoiler:King Boo's boss fight]] nor when he was returned to normal, however.)
* SurvivalHorror: LighterAndSofter (it is a main Nintendo franchise game, after all), but it has its moments.
* TacticalSuicideBoss: All the boss battles except [[BossArenaIdiocy Boolossus]] play out like this.
* ThemeTuneCameo: In an effort to keep himself comfortable, Luigi rather nervously hums the game's theme music when he isn't calling out his brother's name. If the lights in the room are on, Luigi calmly whistles the theme instead. In an effort to keep Luigi ''un''comfortable, the ghosts start humming along with Luigi in dark rooms.
* ThrowTheBookAtThem: Books in the Study will fly off the shelf and into Luigi when he first enters it.
* TokenGoodTeammate: Madame Clairvoya, who's the only portrait ghost who doesn't have evil intentions; helping out the hero and then asking him to suck her up with the vacuum cleaner when she has finished her purpose with helping him.
* TookALevelInBadass: Luigi in this game, considering he's usually the ButtMonkey and NumberTwo in most of the games he's in.
* {{Trope2000}}: The Poltergust 3000.
* VeryFalseAdvertising: The mansion as depicted on Luigi's directions to the place looks ''far'' less menacing and is accompanied by such features as a bright blue sky and [[EverythingsBetterWithRainbows rainbow]]. The lightning strike when Luigi looks up to compare it to the actual mansion drives the point home.
* VillainousGlutton: Mr. Luggs and Garbage Can Ghosts.
* TheVonTropeFamily: Vincent '''van''' Gore, whose name doubles as a reference to the famous painter van Gogh.
* WeaksauceWeakness: ALL of the Portrait Ghosts are impervious to the Poltergust 3000 (or sometimes cannot be fought or even seen at all) until you do something that makes them vulnerable. The method is different for each one (it's easier with some than others) and you have to figure each one out.
* WeaponsThatSuck: The Poltergust 3000.
* WhenAllYouHaveIsAHammer: Everything that needs to be done in this game comes down to using the Poltergust 3000. Luigi captures ghosts with it, sets things on fire with it, puts out fires with it, and freezes water with it. Then again, the game gives you no ability to jump nor any physical attacks, what else is there?
* WindUpKey: The Clockwork Soldiers all have them, which you have to pull off in order to suck them up.
* WoobieDestroyerOfWorlds: Chauncey, the first boss, who can throw a ''mean'' tantrum.
* WorthyOpponent: This game actually implies ''a sliding scale'' for this. Your skill at capturing the gallery ghosts results in one of three different images: one each for a Bronze, Silver, or Gold frame.
** The bronze frame is the worst, in which the ghost will generally assume a bland and uncommitted pose or is slightly obscured, in which case the ghost is deciding to ignore Luigi. For example: Nana's greyed out photograph, Sir Winston's fuzzy traveling image, Sue Pea returning to her upside down posture in-frame.
** In the silver frame, the ghosts clearly acknowledge Luigi, but with clear disdain or resentment. For example: Lydia scowling, Chauncey shrieking, or Melody scoffing.
** The gold frame generally features the ghost's fanciest pose or at its most photogenic, which suggests that the ghost is putting on a bit of a show and wants to be ''thought well of'', that they seek Luigi's respect. For example: Neville posing with his rocking chair, Shivers smiling with a lit candle, the Floating Whirlindas waving cheerfully.
