History Characters / LuigisMansion

* KnightOfCerebus: Becomes this in ''Dark Moon.'' His LaughablyEvil tendencies are completely gone, his wit is far sharper while his snarkiness is more restrained, and he becomes downright terrifying.

* BigBadDuumvirate: Has one with Hellen Gravely in ''Luigi's Mansion 3''.

* BigBadWannabe: Everything she does is just to please King Boo, who is far more dangerous and has bigger plans.

* ItsAllAboutMe: While in the first ''Luigi's Mansion'' he was motivated by wanting to get revenge on the Mario Bros for the trouble they caused his boos, after his first defeat and subsequent SanitySlippage he only cares about himself and his getting his revenge on Luigi and E. Gadd. His value of anything and anyone else is determined by how much they help him accomplish said goal.

* AFatherToHisMen: One of the few redeemable traits he has is that he genuinely cares for his fellow Boos, even going so far as to stage a rescue for Boolossus when he was captured by E. Gadd prior to ''Luigi's Mansion''. By the time the sequels come around, King Boo has more-or-less abandoned this trope, as he never mentions his Boos and puts them in harm's way on at least one occasion in ''Dark Moon'', and he flat-out dismisses his minions as useless in ''3''.

* TheSociopath: In his debut, he showed care for his fellow Boos and worked to protect them. In the sequel, however? He's perfectly willing to eliminate anyone and anything in his path for revenge, and despite having to know by the final battle with him that Luigi's captured at least some Boos (and likely having known beforehand), he never mentions them and only talks about how he will make Luigi and Gadd pay dearly. ''3'' plays with this in that he does care that Luigi sucked up several ghosts when going through the hotel, but in the same scene he dismisses Hellen Gravely and the other staff as "useless" for failing to capture Luigi.

* WellIntentionedExtremist: In the first game, he seemed to genuinely care for the other Boos. In the sequel, however, once he has been personally humiliated by losing to Luigi, he seems to drop this.

** He also chases the player character(s) i ''VideoGame/SuperMarioBrosWonder'' and ''sings'' while doing it.

* TheHyena: They all maniacally laugh in specific ways, usually when they brutally appear.
* JumpScare: Quite a few of them make their entry by suddenly appearing behind Luigi and roaring at him.

* AffablyEvil: In the first game, he treats his minions well and is downright friendly when interacting with Luigi. This goes out the window in the second and third games, where any kindness he displays is completely fake.

The Jumbo Ghost. The third boss ghost to fight and the sixteenth Portrait Ghost fight. In Japanese, Boolossus is the Big Boo fought in the Treacherous Mansion of ''Dark Moon'', and Boolossus returns as the rooftop boss of the [=ScareScraper=] in ''3''.

* CompositeCharacter: In the English version of the games, where Boolossus was ''not'' the Big Boo in ''Dark Moon'', his appearance in ''3'' has elements of both, being identified as Boolossus from the first game but having the burrowing attack that the Big Boo used in ''Dark Moon''.

* TheGhostKing: Being the King of the Boos, he easily qualifies. He even provides the trope image.

* GeniusBruiser: Shows shades of this, attacking Luigi by possessing the ''Tyrannosaurus'' skeleton.

* {{Narcissist}}: According to his name in the Japanese, Chinese, and Korean versions.

* AdaptationalVillainy: He's a significantly crueler, more psychotic, and dangerous character in the ''Luigis Mansion'' games made by Creator/NextLevelGames than he is in the original ''VideoGame/LuigisMansion1'' or spinoffs he appears in, where he is a garden variety KingMook.

* PunnyName: Her Chinese name "贾素妍" sounds similar to "假素颜", which means Fake Nature Face.

* AdorableEvilMinions: Especially in ''Dark Moon'', given that the Boos have adorable voices. Doesn't stop them from carrying out mischievous deeds though.

->''A product of the mansion's fear and despair, he's not sure who to fear or what to despair these days.''

* EldritchAbomination: Much more monstrous in appearance than the other portrait ghosts, this is no doubt because rather than being a spirit of the deceased, he is instead a spectre born from the fear and despair made by the mansion.

* TheSpeechless: He is the only Portrait Ghost who isn't capable of speech, though he does make some grunts of panic when being sucked up by the poltergeist.

* AdaptationalVillainy: He’s a significantly crueler, more psychotic, and dangerous character in the ''Luigis Mansion'' games made by Creator/NextLevelGames than he is in the original ''VideoGame/LuigisMansion1'' or spinoffs he appears in, where he is a garden variety KingMook.
* AdvancingBossOfDoom:

* BerserkButton: She’s a massive fan of games, and if you can’t recognize which game tunes she’s playing on her piano, she throws a tantrum, banging on the keys with her fists. She'll then promptly disappear, and you'll have to leave the room, come back in, and replay the instruments to talk to her again.

* FortuneTeller: She gives Luigi information on Mario’s whereabouts if you bring her objects that he owns (possibly using {{Psychometry}}). Once she runs out of power, she insists you capture her, locking you in her room; she's the easiest Portrait Ghost to capture in the game.

* PunnyName: A pun on clairvoyant. She’s a fortune teller who uses objects to sense where the owners of them are.

* TheFriendNobodyLikes: It’s implied he’s related to the family on the first floor, yet they barely acknowledge him according to his bio.

* ShrinkingViolet: The pink one doesn’t like being looked at.

* BonusBoss: Unlike the other optional Portrait Ghosts, Sue Pea is the most out-of-the-way Portrait Ghost in the game. Encountering her requires you to access a hidden room late in the game, which contains the key to another optional room before the Guest Room, where she sleeps.

* PottyFailure: The way to exposing her heart is to convince her she’s done this while sleeping. Her dolls will start floating your way when you play this, however.

* FlunkyBoss: Would rather send his minions at you than fight himself. Might be because he’s a pushover when you get past them.
* FrenchJerk: He wears sterotypical French clothes and speaks in some French dialogue, and he's not a nice guy.

** [[spoiler:Before the final boss fight in ''Luigi’s Mansion 3'', King Boo attempts to trap Luigi in a painting alongside Mario and Peach. Luigi is only saved thanks to Polterpup tackling him out of the way at the last second.]]

* VillainsOutShopping: Can often be seen performing odd jobs or just idling or goofing off around the hotel. In some instances, they’re so absorbed in what they’re doing that Luigi can walk on by without incident.

* CuteGhostGirl: Subverted. Normally, Hellen is probably one of the most beautiful ghosts you’ll find in the Mushroom Kingdom but that’s because she wears makeup. Without that she jumps straight to the [[GhastlyGhost opposite end and looks more like the ghost of a Haggard witch]].

* PunnyName: Her Chinese name “贾素妍” sounds similar to “假素颜”, which means Fake Nature Face.

* SmugSnake: She’s quick to brag about her planning ability, believing that she could easily gift Luigi to King Boo on a silver platter. She’s flabbergasted when a [[CowardlyLion scaredy-cat]] like Luigi systematically dismantles her scheme and makes it all the way up to the top floor to confront her.

* LaughablyEvil: A stand-out example in a game filled with rather goofy foes. He's cowardly, bumbling and is constantly trying to act like he's in some sort of 70's cop movie, performing clumsy combat rolls throughout the fight.

* ShoutOut: His name, status as a king, and the fact that he’s Scottish point to him being a reference to ''Theatre/{{Macbeth}}''.

* SkippableBoss: There’s nothing forcing you to capture him once he hands over the ninth elevator button. You’ll just miss out on the achievement you earn by doing so and his canister in the Gallery will remain vacant.
* TokenGoodTeammate: He’s more concerned with making movies than doing anything to fight or hinder Luigi, even hiring him as an actor in his latest film and handing over his elevator button freely once production wraps.

* WritersBlock: He’s so distraught over the loss of his megaphone that he can’t bring himself to make another movie.

* ZeroEffortBoss: If you decide to capture him, he has so little health (just 25 HP, exactly 1/4 of what a basic {{Mook}} has) that he doesn't have time to put up any significant resistance. In fact, he’ll likely get vacuumed up normally before you have a chance to slam him.

* {{Expy}}: Being fights in history museums with T-Rex skeletons animated by paranormal activity, the first phase of Ug's boss fright is very similar to the battle with the Black Slime T-Rex from the Wii and [=PS2=] version of ''VideoGame/GhostbustersTheVideoGame''

* AdaptiveAbility: In a sense. If you get smart and have Gooigi stand on the outer rim of Clem’s arena to speed up the fight, Clem will start hurling mines at Gooigi as well.

* LazyBum: He’s ReallyFondOfSleeping, has a very messy room, and he fights while floating around in an inner tube (as if he can’t be bothered to get up and move himself).

* SnakesAreSinister: She has a very prominent snake motif, and she’s certainly evil.

* FunWithAcronyms: The first letters of their names spell NLG (a reference to Next Level Games, who developed the game)

* DiscoDan: Her floor's aesthestic takes a lot of inspiration from disco imagery. She also performs the StayingAliveDancePose a few times. Her Goob crew is more inspired by old-school hip-hop and electro, as is the stage music.

* GracefulLoser: As she’s being sucked into the Poltergust, she does a few last dance moves.

* ThirteenIsUnlucky: If you count the two basement levels, the Twisted Suites take up the thirteenth floor of the hotel, and its three boss ghosts have perhaps the most active presence in terms of hindering Luigi's progress and just generally trying to mess with him.

* AFatherToHisMen: One of the few redeemable traits he has is that he genuinely cares for his fellow Boos, even going so far as to stage a rescue for Boolossus when he was captured by E. Gadd prior to ''Luigi's Mansion''. By the time the sequels come around, King Boo has more-or-less abandoned this trope, as he never mentions his Boos and puts them in harm's way on at least one occasion in ''Dark Moon'', and he flat-out dismisses his minions as useless in ''3''.

* AnIcePerson: When you blow off his Bowser suit's head to reveal King Boo, it starts floating and firing ice balls that can freeze you, something originally intended for Bowser himself in ''Super Mario 64''.

** BigBadDuumvirate: Has one with Hellen Gravely in ''Luigi's Mansion 3''.

A lazy mechanic ghost who is fought on the second level of the basement, the Boilerworks. He attempts to flood the area to keep Luigi away, ultimately engaging him in battle in the hotel's main water tank.
