Fair warning, this is gonna be a long one; see this discussion and this draft page. :boo:


We all know how many iterations the famed "Big Boo" enemy/boss has gone through. But what if I told you that mixed in with those, is an individual recurring character we've completely overlooked?


Here he is! Or wait, maybe that's a normal Boo, darn it...
This is "Boss Teresa," written as either "Oyakata Teresa" or "Bosu Teresa." He was the leader of the Boos until he was basically combined into/replaced with King Boo (more on that later).


Only room for one of us up here, round boy!
He was the owner of Big Boo's Haunt, appearing in three missions. Curiously, in the Japanese release, the "Oyakata" name was used for the first mission, the "Bosu" name was used for the balcony mission, and no name at all was used for the Merry-Go-Round mission. Japanese fansites often try to list them as two characters, usually lumping the MGR one with the first mission's one due to requiring normal Boos being defeated to spawn. Despite this, official sources treat all three as the same, generally using one name or the other. The same goes for following games, where they generally consistently use one of those names.


Basic to blue
Hudson Soft liked this guy enough he appeared in the early Mario Party games. Notably, he was a board feature in 2 and 4, in the latter of which he was a curious blue color. This is most likely so he has a distinct icon since in that game, all talk icons have a neutral pose facing the screen, but it may also act as a callback to the standard Atomic Boos having a muted periwinkle color in Super Mario World, like at the top of this thread.


Don't inhale him. Really, don't, it's not worth it.
Large-sized Boos that may be him appear in certain minigames as well, like Running of the Bulb here from the first game. Neither English nor Japanese in-game descriptions mention the big fellow at all, though I'm hoping the official Japanese guide may shed some light. That being said, Japanese sites like Pixiv Encyclopedia call this one "Gasu Bosu Teresa" (Gas Boss Boo, of course) owing to his foggy appearance. There's also large-ish Boos in Pedal Power and Skateboard Scamper, but until further notice they seem to just be normal Boos. Mario Party-e was US-only and involved in a SMW-based minigame, so it makes the most sense to consider that a normal Big Boo and not the Boss Boo character.


I may not be big, but I AM the KING! King enough to crush you!
It's at this point King Boo is introduced. Here, he's oddly colored with a minty green body, minty blue tongue, and minty pink eyes. He's also only the same size as a normal Boo, much smaller than Boolossus from the same game (though bigger than Boolossus's constituent parts). Pre-release materials seem to depict him as a normal Boo, even, with no crown in sight.


What? I'd trust him. A tongue like that can't afford to lie.
It's at this point we reach the second mainline appearance of "Boss Teresa," this handsome devil (according to the fanartists, at least, image search ボステレサ at your own risk). With his slobbering mouth, huge tongue, and distinctly pudgy appearance (despite Boos already being spherical), you'd think this was a separate character entirely... if not for the 30th anniversary official Super Mario Pia Japanese guidebook explicitly stating that he is the same character as the SM64 boss - and he is still massive compared to the LM character. Which brings us into...


Hell to unlock, but worth it. Especially when you also get the Boo Pipes and become the most OP racing team in history.
...King Boo's often-decried 'basic bitch Boo' redesign in Double Dash!! But wait, it gets interesting here: unused text strings in the internal data refer to the ghost not as "King Teresa," but "Boss Teresa," implying he was meant to be the character from before until very late in development. But wait, there's more! The finalized design can be seen in materials at a very early period of development, implying that this white-bodied, large-sized, normal-crowned design was envisioned as a redesign for Boss Teresa, combining aspects of his SM64 and Sunshine designs into a more standardized appearance (ignoring the out-of-house MP4 design, releasing between LM and DD). Why did they change it to the LM character? Probably for marginal advertising/representation from LM. Granted, they could have had the best of both worlds by editing the final model into a separate slot for the LM King Boo, having them both be on a team with Boss Teresa being heavyweight and King Boo being middleweight, and giving them the classic Boo item as a special, while making Petey's partner be Big Bob-omb or another character, but hey, that's hindsight. If you think this makes Boss Boo and King Boo a singular character, then there's something to further bump things up with...


Tired of the carnival music yet?
Super Mario 64 DS, where along with the original Boss Teresa appearing in his old role (with a spiffy new model to boot instead of an upscaled Boo model, though this just means he has better animations than them), the MKDD King Boo appears as the Luigi-unlock boss, using the stock throaty-laugh sound effect King Boo did in LM. However, they are not fully distinguished either; they use the exact same "spiffy new model," with basically an on/off switch to determine if the crown is there. Their behavior is also not much different; King Boo fights in front of a mirror, and usually only his real version or his reflection is visible at any given time, and he can also spit blue fire like a Flame Chomp and occasionally slowly teleport when switching visible sides. But wait, there's more! The English script refers to both as "Big Boo," and while the Japanese script does use "King Teresa" for the crowned one, that's on top of the "Oyakata Teresa" and "Bosu Teresa" already in use! Meanwhile, the French localization uses "Roi Boo" for both, meaning "King Boo."


Considering the size of his tongue from before, he probably needs that size of mouth.
"Boss Teresa" appears one additional time shortly before SM64DS as a boss in Mario Pinball Land, again being on a similar level of importance as the (highly off-model) Petey Piranha. He's gone back to looking like a giant-sized standard Boo. Also, the Japanese name is again inconsistent; while the (presumably Nintendo-written) official site still calls him "Bosu Teresa," the (third party-written) official guide uses "Biggu Teresa," which is shared with Big Boo from SMRPG (which I severely doubt was intentional, considering "big" is a generic loanword and it's highly improbable that they were inspired by an obscure line in SMRPG's instruction manual; "Biggu" is also primarily associated with Yoshi bosses that Kamek enlarges, though oddly not Bigger Boo). He never made any fully new appearances again, though as of this writing, he has appeared more recently than King Boo thanks to an MPL-inspired WarioWare microgame (where he is unnamed).


Judging by the skin texture, he's a marshmallow. Stay Puft, perhaps?
King Boo takes an appearance similar to his original one in later Luigi's Mansion games. Despite this, influence from the MKDD design is still present, namely the white color and his massive size. Even in the LM 3DS remake, while he's back to his normal size and some of his other colors are reverted, his body is stark-white.


I warned him he should have kept a bottle of ghost milk on hand.
So, what happened?

The decision to swap his character out for King Boo in Double Dash!! while keeping the design intended for him was essentially the death knell of this character. It left him with barely any distinguishing characteristics (besides his wonk Sunshine design) and little reason to continue appearing in spinoffs if they could just have the more popular and distinct King Boo do so; King Boo even replaced Boss Teresa's old board role in Mario Party Superstars. He's well past the point where he's likely to make a comeback in any form unless they decide to remake SM64 from the ground up, which is unlikely at best considering they seem satisfied rereleasing it in a limited-time compilation or an even-more transient subscription disservice. One could say that he was a prototype King Boo from the beginning or even an early iteration of the same character, but much as Koopa Kid was for Bowser Jr., they coexisted in the GameCube era, though unlike KK and BJr, they managed to appear in the same game (albeit intrinsically linked).


It's bol against bol
It needs to be decided how to handle this on the wiki, because lumping him in with all the other Big Boos out there is clunky at best; these are more removed from standard Big Boos than many instances characters and species we do have split from each other. So, hit me with your thoughts on this (that was a bad pinball boss joke to tie into the above image, sorry). Anyway, responses are open.

Can you name and cite these sources? I don't see anything on the wiki of this sort. The wiki simply treats the SM64 instances as different Big Boos.

That is because a majority of the names are in-game regardless of language. Every guidebook has treated them as a singular entity across languages, though, from what I can tell, as does Mario Portal. For what it's worth, "Oyakata" has specific connotations that indicate there being just one, more as a housemaster.
This is what Super Mario Pia has to say:
  • Japanese:
    登場作品 S64,SMS
    Bosu Teresa
    Bosu to shite tōjō suru kyodai Teresa. "Sūpā Mario Sanshain" de wa ōkina bero o dashite iru.
    Tōjō sakuhin S64, SMS

    Boss Boo
    A giant Boo who appears as a boss. In
    Super Mario Sunshine he has a big tongue.
    Appeared in works S64, SMS
I still don't have proper citations for "every guidebook" and I have no idea how reliable the Pia guidebook is in relation to what the brand supervisors and game creators actually intended this character to be, but the Mario Portal site alone may well represent a consensus among said creatives. In that respect, I think it's worth highlighting that Big Boo is only given one entry on the portal's SM64 page and only with the "Oyakata" descriptor, indeed suggesting you only ever fight one particular Big Boo in that game. I'm still holding off from splitting this guy from the "Big Boo" species because I need to mull on the particulars a bit more, and I'm certainly opposing its merge with King Boo.
The Big Boo from SM64/Mario Pinball (who is also purported by the Pia book to be the shitty "King Boo" you fight in Sunshine)

If I'm understanding correctly, the case you brought here has three actors, no? Those being the aforementioned Big Boo, the King Boo from Sunshine, and King Boo proper. I didn't exactly skim the topic but I also didn't quite study your case in detail, so there are things I could be misunderstanding.
Yeah, and I'm wanting to change the classification of said actors into Big Boos proper (ie, the ones that in most cases are standard enemies), the "Boss Boo" who wasn't given a consistent localization or design, and King Boo proper - who was given a redesign intended for "Boss Boo" that combined his SM64 and SMS designs.
