My theory is King Boo's design is based on the game he appears in, the Luigi's Mansion games are scary, so they make him look scarier.

The reason why King Boo looks different in the Luigi’s mansion games is bc (not only go fit the spooky aesthetic of the game) but also bc of the Crystal that’s on his crown. Whenever he doesn’t have the Crystal on his crown, he just resembles a normal big boo with a crown, however the Crystal has the ability to alter his appearance. I just felt as though that everyone thought this lmao

Actually, think of it, whenever he has a crystal on his crown he has the Luigi's Mansion look. Maybe he needs the crown in order to change his appearance. Even in the Mario Movie, he lacks the Luigi's Mansion look.

I saw a theory video a few years back and they suggested the reason for the alternate appearances is that the Luigi's Mansion version of him is how Luigi perceives him because he is just that scared of King Boo verses how he actually looks in the Mario games

I personally have a headcanon that the basic King Boo we see in the regular Mario games isn't the actual King Boo, but rather a stand in to make public appearances, while the real King Boo (the Luigi's Mansion version) keeps to himself in secret, kinda keeping in line with how Boos themselves tend to hide a lot

King Boo is one of my favourite characters in the Mario universe, and obviously I think that the Luigi’s Mansion version is way better, with his crystal crown, menacing eyes and awesome personality. I hope they eventually make a canon transformation between the two, so we know how they work! And I also hope we see the Luigi’s Mansion version in games other than LM.

It would have been nice too if the wonder event could possibly change the way King Boo looks throughout the level as you go along, so maybe the first third of the level he looks like he does in the trailer, then 2/3 of the level in you see his crown changes, then the final third of the level you see him phase and morph into the Luigi’s mansion King Boo. Now that would be dope as heck. And that would not be too far fetched given the wonder events already do crazy and very out there kind of stuff so it wouldn’t detract from the overall experience at all. That’s how I would have done that level, and also the further along in the level you get, the more twisted and scary the singing becomes from King boo and all the other boos. Still sounds beautiful from start to finish but becomes more horrifying throughout the level. In all honesty though I just hope Haunted Boo house levels will really twist and mess with our minds like past 2d Mario games have done. Especially with wonder abilities, it’s a no brainer.

my personal theory is that the 'normal' king boo is just a figurehead for LM King Boo to hide behind. Basically keep up appearances while the real king works on how to get rid of the mario bros. But after 3 major failures he's gotten desperate and has finally started making more public appearances like in MKT to try and take out the bros more *directly* public be damned Is this too deep for a mario game? maybe so but i still like it

The "Regular" King Boo is just a Big Boo with a cheap crown, I don't understand why Nintendo doesn't use the Luigi Mansion's design for the character, even Boolossus who is just a Giant Boo with yellow eyes and a purple shadow(?) around his eyes looks better than Regular-King Boo

They are the same king boo it's just in the luigis mansion games he uses the gem on his crown to give him more power and ti change his appearance which is why luigi takes the gem at the end of every game

My theory in lore theory is that Big boo is king boo and he just switches between using the crown and not because he’s a cover up for the real King boo for when he gets stuck in painting in the Luigi mansion games

I like them both tbh. Since the gem is canonically broken, maybe we could reach a halfway point, where he still has the shady red eyes, and blue tongue?

Coincidentally... They're the SAME King Boo because of Super Mario 64 DS since he captured Luigi because of what happened in Luigi's Mansion. People keep forgetting that the big gem on top of his crown is what gives him more power.

I believe King Boo's crystal crown is what alters his appearance. In Dark Moon, you see some ghosts getting powered up by crystals in the Old Mine, which then alters their appearance. My personal headcanon is that the crystal in King Boo's crown is that same type of crystal

My guess is that his look depends on that spooky pink crystal in his crown

The reason for the scarier King Boo variant is the crystal on his head that transforms him and makes him stronger.

I like to imagine the reasons they look different is that there's multiple king boos for each haunted mansion, sort of like a queen bee Then the luigis mansion king boo looks different because hes the grand king boo, like king of king boos, the one that assigns king boos to their respective mansions It acts as a good contrast between miniscule mansions from the mario bros games and the gigantic mansions in the luigis mansion games

My theory is that whenever he wants to bring terror to the mushroom kingdom, he wears the crown with the crystal to make himself scarier and stronger, but whenever he is just ruling his kingdom, he wears his normal sunday criwn

The best we've got is "Angry Boos" from Super Princess Peach. Regular Boos that are absolutely furious have eyes a bit like King Boos, so that could be the explanation. King Boo is extremely enraged during the Luigi's Mansion games and thus looks like an Angry Boo, and a normal Boo otherwise. But despite that working well, assuming Nintendo is keeping up with Super Princess Peach lore this whole time is a small stretch, but I think its the best we have as it being the Jewel has been disproven

I like to belive that the mainline design is a "base" form where he looks more like a standard boo and is less powerful and not as much as a threat as he could be because he is missing the gem from his crown that could signify his "true" power. This would explain the more menacing design for when he is the main villan and would tie in with him usually loosing the gem when defeated and captured as he would be returned to his base state ready for his next in game appearance

6:49 the big the cat got me😂

Now that the game is out I think I can safely say that King Boo in Mario Wonder is just a regular Boo that has been powered by a Wonder Flower.

Both king boos are the same character, it all has to do with the gem in the crown. That gem changes his appearance like a power up of sorts.

I think that there actually are two King Boos. If you notice, most kings under Bowser's army have the crown with the jewels, such as the less-cool king Boo. LM King Boo's crown doesn't have those gems. Usually when we see jewel-crown king boo, he's working under Bowser, while LM's King Boo seems to be his own leader. My theory is that LM King Boo doesn't work for bowser, or at least not after LM1 if he was. He's his own king that rules his own portion of ghosts and boos separately from Bowser. With how frustrated he gets from incompetence as shown in LM3, its safe to assume he may not want to work under Bowser. Less-cool King Boo is Bowser's king boo. The one that works for bowser and rules over the ghosts in the army itself. It's possible that LM king boo may have ruled under bowser for a time, going along with how the other kings look unique, but may have broken off due to him percieving Bowser as incompetent, which may have led bowser to give a boo a crown just so there was a King Boo for the army.

I do think the Luigi's Mansion King Boo is better. But the reason why I also like the regular King Boo is because of a cute aspect - The thought that only a crown makes this Boo different and in control of all the others. Like, the boos' egos are so fragile that they'll worship another regular boo just because he has a crown. Or, there's the thought that the crown doesn't have magical power but just gives King Boo the confidence to be very powerful. If I'm being honest though, Nintendo probably doesn't have a good reason in their heads like this for keeping King Boo so basic. And the Luigi's Mansion King Boo is still better because it's a more creative design.

Oh yeah, Mario wonder is releasing in 18 days. Let's gooo

I feel like the reason they don't use the LM king boo design instead of the base one is for more than one reason (At least from my viewpoint) Firstly, I think the tone of the games is one of the reasons the more basic King Boo design is used over the Luigi's Mansion one. Mario games, mainline especially, are mainly fun adventure platformers. It's meant to be more kid-friendly and or brighter/saturated. They're more lighthearted, unlike the darker, more ominous atmosphere of the Luigi's Mansion games, so I feel like to match the use the regular King Boo. Secondly, I also thing color palette also has something to do about it. If you really think, a lot of Mario enemies use greens, yellows, reds, white and other brighter colors. Luigi's Mansion King Boo, at least the more recent version, uses more purple and darker tones. And yes, villains like Antasma use purples as well but he only does appear in a spin-off series. But for a character that appears as often as King Boo, going for something that matches the colors for the main games works better. (If the LM 1 design was still around with the red gem, red-ish eyes and blue tongue, that could be a better fit) Finally, as you said. It's the LUIGI'S MANSION design. Why would the team use the design reserved for the LM games in a mainline game? Sure they might throw some fan-service here or there in spin-offs, but nothing major. And King Boo isn't the main focus for the main games. It would be weird if they designed King Boo that jarring if he isn't even going to be important to the main plot. But really, I don't care about what King Boo looks like. I'm a simple woman-

Luigi takes the gem in King Boo's crown every time Luigi beats King Boo, the scary eyes and tongue could be because of the gem.

There's a reasson they keep them seperate. Having the more sinsiter King Boo design within Luigi's Mansion presents him as a serious threat to everyone, and if he were that SAME image throughout every appearance like Mario Kart or Mario Party, that presentation and effect we get from seeing him is essentially lost. *It's essentially the SAME reason nobody takes Bowser seriously anymore in games.* He's a joke and the only way he could be taken seriously again is from a complete overhaul in design like in Bowser's Fury. King Boo serves as a balance. He portrays a villain that the universe desperately needs (Luigi's Mansion design), while also serving as a character that people love to see without the status of him being a villain being tainted (aka his regular simpler design). I also prefer the simplistic design but would also love for them to bring back that ghostly green glow he had from the first game!

My theory is King Boo's form varies depending on how much power he has. Notice how King Boo in Luigi's Mansion is a reality altering god while King Boo in anything else seems to be more reliant on gimmicks and parlor tricks. How intense King Boo is depends on if he's THE villain of the story. He has a lot more to lose when he's running the show as opposed to when he's just another pawn of Bowser or whoever. So naturally when there is more risk to his turf he goes more all out, which alters his physical appearance. Kinda like any character with different power forms.

Someone already said it, but I believe it's the crystal on his crown that makes him look like that in Luigi's Mansion. If they are going to make a Luigi's Mansion movie, maybe they'd have King Boo obtaining the crystal and he then gains his LM appearance.

The look of King Boo maybe is different because when he is in Luigi Mansion, he uses a purple gem to control other forms of ghosts, and when he is en Mario's game, he doesn't use it because he just controlling just Boos 🤔🙂

I think that King Boo in Mario Games are just variants of the real King Boo from the Luigi's Mansion Games.

Ok, so here's something I want to say. In the gameplay provided for the Mario Wonder scene, there's a timer at the top that's ticking down. So maybe, the King Boo scene in the trailer is just a wonder effect like turning into a goomba. (Looks like someone forgot to watch the Super Mario Bros Super Show) Jokes aside, what if King Boo actually ALSO becomes a boss with his LM or even a brand new design that comes from the effect of a wonder flower. It's certainly not too farfetched since Bowser Jr. went through an interesting design change in the boss fight that we saw of him, and Bowser... Well, you know. So maybe this could be the case.

Luigi thinks he is scarier, so that’s how he appears.

6:49 OMG BIG THE CAT

I have to say I haven’t been watching as many of your videos recently so I’m not entirely sure if this is a new thing… but I haven’t heard much about the whole debacle, and I figured here’d be the best place to stay updated. But I must say, I love the new ‘spontaneous’ editing style. Definitely gonna tune in more going forward! :D

I feel like in the movie to make king boo “not goofy,” perhaps the gem that king boo will probably steal will change his appearance as well as giving him new abilities

My theory is that the Luigi’s mansions king boo is “too scary” for a normal Mario games made as a “kids” game so it would “scare them” Which I think is dumb

Did you see in wonder how that "king" boo turned into a regular boo and was decriwned after the wonder affect?

This is my belief on the king boo confusion here, they’re both the same king boo, its just that crystal on the crown that makes them more evil.

0:11 AGREEMENT. There is no such word as "agreeance"

King has been trapped in a painting and a jar the entire time. They to hire an actor

2:16 THERE I AM GARY THERE I AM

Wild prediction: king boo has phases and the final phase in wodner is the Luigi's Mansion design

Idea #1: I think normal king boo should be a boss battle and once you kill him he comes back in a cool cut scene as Luigi's Mansion king Boo Idea #2: normal king boo should be HUGE. Not just a slightly bigger version of a boo, but HUGE. This could also make him distinct from normal boos. This way there could be two different king boos that are both cool. Idea #3: Normal king boo is the main boss. It would make sense. He is gathering wonder flowers and seeds to destroy the flower kingdom. He seems like he would know about wonder events too. Once the player finally reaches him he is too powerful and uses an army of dry bones and boos to destroy the kingdom. Mario could even ask kingdoms from Mario oddesy to help. The level would have lots of enemies in it and in the background and foreground like with the stampede stage. There would be the wonder event squiggle things everywhere Idea #4: Mario asks dk for help with the war and you get to play as him and smash through dry bones and boos until king boo shows up and uses his jewel crown to transform into Luigi's Mansion king boo. Idea #5: Bowser is still the main boss but once you defeat him, he turns into a super strong and cool looking dry bowser that makes you go all the way back to the starting level. There is a big cut scene of him destroying everything with fireballs raining from the sky and stuff. You can redo all the levels now except they are being destroyed. Dry Bowser can appear in the castle levels and you have to fight him.

I think it is when king boo has the purple gem in his crown, he is the king boo from Luigi’s Mansion and when he doesn’t have the purple gem, he is the regular king boo.

I saw a theory video that basically describes them as the same character since they have similarities in their crowns but one day the main line king boo came across a gem that gave him power but also corrupted his appearance and personality to make him even more evil. If there is a luigi's mansion movie on the horizon, I personally think that would actually make a really interesting plot; king boo gets bullied by the other "kings" (bowser, king bob-omb, etc.) for not being any different from his lesser counterparts, he finds the gem and terrorizes not just Luigi and friends but even the other villains as well.

Honestly, while I much prefer the Dark Moon design. King Boo is one of my favorite villains and I think both designs are amazing regardless. I’m just happy to see him in the new game

A very special thing that only Luigi Mansion King Boo did was he gave the mysterious power of the Boos life. This life is Boolossus.

I like to think that King Boo’s design in Luigi’s Mansion is just him antagonizing Luigi. He makes himself look more menacing because he wants to intimidate Luigi, but in other games he’s just trying to have fun. In Sunshine… I dunno, he’s at a casino so the tequila is hitting

Luigi's Mansion 3 is clearly a dream that Luigi has to get out of. The game literally forces you to sleep before king boo appears.

when you think about it, king boo from luigi mansion is always (or almost) stuck in a painting. the mainline mario version is alway free and also outside of hunted house most of the time.

I can say this is a certified "Among boos" situation.

King Boo: Ugh... another Mario Kart race. Big Boo! (Throws Big Boo a plastic crown). Go in my place.

I'm glad someone's finally pointing this out. Now can we discuss the absence of E Gadd and Toadsworth from Mario Kart??

this video made me think of a cool little head canon where the king boo in the luigi's mansion game looks more threatening because that's how luigi sees him but the king boo in the main line games looks less scary because mario is more used to big bads and doesn't see him as much of a threat as luigi does.

My theory of why king boo looks 2 separate ways: *(This is all speculation and I am pulling this directly from my own boo/Mario based lore that I created so most of it is not directly shown in any Mario/Luigi's mansion game)* The gem atop the Luigi's Mansion king boo obviously has some connection with the dark moon. same material, colour and overall similar effect as shown in Luigi's mansion dark moon However I don't think its the dark moon itself, rather a type of energy that the dark moon produces I call it shadow aura! Boos use shadow aura to do stuff you would expect a boo to do: Example: create fake blocks and doors, use psychokinesis to pick up items, that kinda stuff but also some things that aren't shown in any game, such as creating aura weapons/items and making portals All of these stuff require shadow aura to use However each boo has a cap and a limit on shadow aura The cap is the point of which a boo stops gaining new shadow aura from the dark moon (which supplies shadow aura to each boo) But the dark moon isn't the only way boos can gain shadow aura, They can also gain shadow aura if either 1) They absorb it from another source (another boo) or 2) They experience Heightened emotion (e.g: Anger, grief, sadness) If a boo gains aura in either of those ways, it will boost their aura past the cap up to the limit However the limit is... well the LIMIT. No more shadow aura can be gained past the limit. But if a boo happens to hit the limit, they will be overwhelmed with power and rage and go on a rampage of which the boo in question is not in control of a rampage only ends once a boo's aura is reduced to none (btw a boo drains aura faster then the dark moon can supply it while in a rampage) Anyway, back to king boo. If the gem on his crown truly is from the dark moon, that would mean that it supplies constant shadow aura. Meaning that when king boo has it on their crown, then that means that their shadow aura will be instantly maximised and they go into a rampage! But the rampage doesn't end until shadow aura is depleted, but since the gem constantly supplies shadow aura, the king wont stop their rampage unless the gem is removed which allows the shadow aura to deplete once again, returning the king to their Normal form

Okay, I'm going to assume that most of the King Boo appearances we see are all the same King Boo... _Except_ the on on Isle Delfino, because he looks wayyyy different from the other two designs and even has that shell-shaped tail (Why would King Boo be running a secret casino on Isle Delfino anyway?). But the reason the King Boo in main Mario games looks like a normal Boo is because in _all_ the Luigi's Mansion games he has a seemingly magical gem embedded in his crown. In all the Luigi's Mansion games he seems to have a HUGE power boost. So it would make sense that his boost in power would change his appearance and make him more threatening/scary.

1:35 release day. He appears in a stage and sings A Night at Boo’s Opera. It’s a fun segment of the stage.

The Luigi's Mansion games take place at night, so I think he just has those dark bags under his eyes because he hasn't gotten any sleep.

I think the King Boo in Sunshine was just a creation of Bowser Jr’s magic brush, as it explodes into goop when defeated.

King boo: There's a million gruesome ways to die Barnaby: Wow, how original

King Boo my beloved.

its really annoying how people dont think "hey, the luigis mansion version of King Boo always gets captured at the end of each game, and every time he reappears hes usually been let out by an exterior source, so maybe, since that King Boo keeps getting caught, Big Boo was promoted to be the new King Boo"

I honestly don't care what King Boo appearance looks like.

I like the theory that Luigi's pov makes King Boo look scarier. Sure, give KB more detail otherwise, but the idea that Luigi tells the other cast members about the super scary ghost and they just dont see it the way he does is a funny idea

Nintendo has FORGOTTEN about Mario...

my head canon in why king boo looks different in main Mario games and Luigi's games is because king boo gathers negative energy when in a normal Mario games that makes him more aggressive/more evil his body changes in the Luigi's games once hes full of evil, when he gets beaten by Luigi he returns to his more docile more rational self maybe something of a double personality that changes his attitude from time to time.

My idea is that King Boo is just a giant boo with a crown when he doesn’t have the crystal in the crown, so maybe in between Luigi’s Mansion games in all of the spin-offs he’s in, he’s just trying to find the crystal to give him his true powers

Im pretty sure its cause luigi takes his original crown in luigis mansion so he gets the main series crown after and then the one he gets in darkmoon and LM3 is basically a form for him seeing the power boost he gets from it and it vanishes at the end of LM3 so I think its more a lore thing

When ever questions like these pop up I always chalk it up to Brand recognition. Pretty sure the Luigi's mansion version and mainline version are the same the only difference between them is that gem on his head makes him more menacing. The Mainline version seems to be the "Marketable" one since its basically a common enemy with crown on its head.

I never understood why people make such a big deal out of Big Boo's design change. Design reason: Look scary for Luigi's Mansion, look less scary for other Mario games. Lore reason: King Boo gets more powerful with a jewel in his crown.

The most logical explanation is that Nintendo doesn't care and each saga on it's own has their unique canon (Luigi's Mansion is different from 2D Marios and 3D Marios) Mario game have never had that much of a continuity, is not Zelda or Metroid.

I love the intro. Great work on your videos. I love your videos of my favorite one. Is the bomb bill evolution. Keep up the good work.😊

I believe that King Boo only assumes his Mansion design at night as we never see him appear that way in the day.

I say that he looks different when he wears the little gem that he wears to make the ghosts evil.

Someone give this man his gem

So far nothing has disproven that Luigi's Mansion takes place at the end of the timeline, so my headcanon is that whenever Bowser is killed off and the koopa army is completely disbanded King Boo became sour and moody and thus got the sunken eyes. Without bowser breathing down his neck he also had the time to find the magic stone in his crown which gave him more power.

I wish King Boo's official appearance would be recognized as his appearance from Luigi's Mansion since it's the series of games that introduced him as a main antagonist. I always think back to him being playable in Mario Kart Double Dash and back in the day questioning why anyone would've chosen to design him as a standard boo wearing a standard crown when they could've given him his distinguished look from the mansion games. It's like choosing any ol' boo, making it slightly bigger and accessorizing it with a hat that just happens to be a crown. Idk but that just always rubbed me wrong. King Boo of Luigi's Mansion ought to be the definitive King Boo.

It's the same character. Nintendo just changes his designs when it feels like it. Also sunshine king boo is just a drawing made by the paint brush that koopa junior had.

The actual King Boom on the right in the Thumbnail looks sick! His main defining traits are the cool gem crown, purple tongue and menacing haunting pupils👀💜👻👑💎

Cut the Sunshine King-Boo some slack, he's drunk

Sunshine's King Boo is really underrated. I love how weird he looks, he's honestly my favourite take on the character. And his scream is just priceless!

King Boo, Big Boo, and Goofy (Sunshine) Boo, should all be their own individual character.

I thought for sure I was the only one, but apparently not! And I'm really happy about that, because Luigi's Mansion King Boo is awesome! That version of him should absolutely be more represented in games!

Don't start with King Boo in the Super Mario Bros Movie... **shudders*

The way the eyes glow, I thought it was Queen Boo.

This just further proves that the LM King Boo is Bowser as Bowser is canonically dead in the LM Timeline, the King Boo we see in Wonder that isn't the LM design, is either a different faction leader OR gets replaced by Bowsers King Boo when he eventually perma-dies. Edit: To Clarify I'm saying that Bowser dies at the end of the timeline for the mainline games, which is why he isn't resurrected and which is where the Luigi's Mansion series starts.

Normal king boo may be Luigi's mansion's king boo's servents. (There may also like 2 or 3 of them)

One guess I had is that the mainline King Boo is just a captain that orders the boos under Bowsers control. Bowser seems to have access to many certain enemies, including boos to some extent. However, some games imply that not all of the species of enemies are under Bowsers rule. There ARE passive boos, goombas, koopas, all those things around. So, what if LM King Boo is an actual monarch of the ghosts. Or at least a self-proclaimed one. It could explain why he rarely ventures out of the mansions he lurks in. And why in said mansions he resides in are a lot more intense ghost wise compared to the mansions Bowser seemingly takes over. This would explain why he doesn’t appear in mainline games since he’s just stuck to some specific places. Whereas the King Boos Bowser control can patrol a variety of areas in order to defeat the Mario Bros. This guess kinda gets ruined by the Bowser transformation we’ve seen from LM King Boo… but who knows. It doesn’t completely disprove the idea.

I have 2 theories 1.The Luigi's mansion version is how Luigi sees him so even if they're in Mario Kart Luigi would still see him as the version with red eyes and a jewel crown. 2. Its another King Boo that rules a differently Ghost/Boo Kingdom. Similar to how Princess Peach rules the Mushroom Kingdom and Princess Daisy rules Sarasaland. You could even add to that by making the Mario Sunshine King Boo a 3rd king that rules another Kingdom.

We’ve never had a king boo in a 2D Mario game before 1:22 people always forget about NSMB2 so underrated

Fun fact: Original King Boo is actually the one from Luigi's Mansion as that was his first appearance

It's definitely a choice. I guess they do want the two Series to Stand out more from each other. Since the Ghost Designs for Luigi's Mansion are unique to that Series and the Biggest Example of this is Both Luigi's Mansion 2 and 3 have a Monster Plant Enemy. that's fully unique. Rather than Using a piranha plant While I can Understand people wanting Luigi's King boo to be Standard... A another Part of me wants King boo to stay In Luigi's Mansion. Tho that's just irrational Fear. that it will like to a Modern Paper Mario thing with Luigi's mansion and we end up losing so many Unique Designs as a result. Plus it really helps Gives Luigi's Series a Stronger Identiy Like How Sunshine stands out a lot from the other 3d games for having redesigns of Stable Enemies in it there and only there.

3:08- yeah THAT King Boo is probably a fake created by Bowser Jr., which makes sense because King Boo from sunshine looks WAY different, and more drooly

When he has the crown, he has the ability to control ghosts which is why we only see I'm with his gem when he's controlling over ghosts when Luigi takes the gem from him to make him go back to normal, he goes back to just a normal crown, yeah, it's that simple.

If King Boo where to sing and have a voice when your running away from him then that would be amazing

As much as I prefer Luigi’s Mansion King Boo, I like him staying there. I see them as two different characters. One that works under Bowser, and one that’s his own villain

King boo: who are you Luigi mansion king boo: I’m you but better
