3 SECRET Pokémon in Pokémon Scarlet and Violet That You Don't Get to See 

I think Greavard could theoretically be reborn from any dog-like Pokémon, not necessarily a single species. There's a book in the academy's entrance hall that talks about Ryme, and how her "Puppy Pokémon" (a category shared by a number of Pokémon) came back to her as a ghost type after she wrote a song in his memory. Sure enough, she has a Greavard named DJ G-Rave who she won't send into battle.

I took greavard's dex entry to be more open ended and apply to all dog Pokemon. If a herdier dies without human contact it becomes a greavard, rockruff dies it becomes greavard, tamper becomes greavard, etc

Rotom loses its Ghost type when it enters an appliance. I think Varoom could be a Gastly possessing the engine as they are also everywhere here in Paldea.

The Secret Terrestrial Pokémon is also mentioned in the Violet/Scarlett book in the entrance hall at the school. It's not named there either, but it is described with glitchy text and I'm pretty sure based on the context clues that it is called "The Disk Pokémon"

Scarlet and violet are the most fun ive had with a pokemon game other than Legends

I fully expect the secrets of Area Zero and the Pokemon responsible for Terralistiztion to be the focus of Scarlet and Violet's eventual DLC. There's a ton of things we just don't know about Area Zero, such as why it feels like a completely different world.

In the academy you can literally read the scarlet/violet book and there is a page showing the third legendary

I would LOVE more paradox forms. In particular, I’m holding out hope for some love to Tropius. Would love to see maybe an ancient form grass/dragon type!

i think in the scarlet/violet book there is a picture of what could be the pokemon that Hoops mentioned first. it makes me believe that the DLC could contain MAJOR adventure in the crater.

Based off what we saw in PLA, Quaxly’s third stage is most likely the regional variant to its original region. Perhaps a another type based off the dancing traditions of its origin.

I think Terasq would be a good fit for the Terastalizing Pokemon, based on the Tarrasque, a dragon from myth and one of the most legendary monsters in D&D, often depucted with an indestructible hide/shell. It would be an amazing legendary, especially with the proximity France has to Spain/Portugal.

2:36 it is possible that the name is actually 12 characters long. In the violet book it has a page on this mysterious pokemon and each square on the page covers two letters. For those looking for the book it's in the school lobby in the pillar bookshelf on the right

The third legendary which is the origin of the terastal phenomenon is supposed to be a Faberge Egg like being. This might actually just be it's dormant state since most of the third legendaries or trio masters that Pokemon have revealed in the past few generations have had a second form that's not initially revealed to us. Like complete Zygarde, ultra Necrozma, eternamax Eternatus etc. So this particular Pokemon could be an egg that hatches or transforms into something else at full power.

Another secret Pokémon mentioned would be the Pterosaur that supposedly died to become Flutter Mane in ancient times. Can't wait to see the fanart people make!

Man wouldn’t it be funny if the third version legendary was the terastilizing origin and debuted in the anime first

The first Terastal related Pokemon is actually hinted further in a copy of the Scarlet / Violet book seen in the Main Hall of the academy, stuck in a bookshelf. It's one of the last pages, the one with all the blanks in it. There's also a hint to a potential fusion of the Legendary Beasts!

I feel like the Varoom one is maybe a Ghastly or Gengar? It says a poison type possessed it. To me a ghost type would easily do that. And Gengar is Poison Ghost

The terrastilization book could be mentioning Zygard. There's a lot of hints in the pokedex that this takes place in a world with Mega Evos.

Quaxly's is a reference to the fact Quaquaval is a peacock, although it was because royalty brought Peacocks to Spain rather than migrated.

I read the book that mentioned the dog coming back as a ghost early on and kept expecting Arvin’s Mabostiff to die and become a Houndstone

What's far more interesting to me, personally, is the strange origins of the "original" paradox Pokemon. The professor's time machine is said to be the source of them leading into the end game, but we know fairly earlier that the original exploration team sent to Area Zero encountered them as well... 190 years prior to the professor's excursion.

I could totally see Quaxley being the starter for another legends style game down the line, and maybe unlike the legends arceus starters Quaxley would actually originate from the region this game is set in

I just love that they are doing the Ultra Necrozma treatment but in a DLC way

I have a theory: The first secret pokemon you mention may actually be Arceus, or somehow related to it. The name has 6 characters like the text boxes, it mentions "hexagonal plates" and while in the games the plates are rectangular, the Jewel of Life movie displays the plates as hexagonal with a similar texture to the terastal crystal stuff. Finally, the plates give arceus a specific type like how tera types work. Also, the time stuff makes sense because Dialga controls time and Arceus is the creator of Dialga. However, it does describe an interlocking "shell" so perhaps its another form of Arceus, or alternatively another legendary created directly by Arceus

The Pokedex says that the fire bird that sits on Skeledirge's head has its own soul, so it technically should be considered another pokemon.

Glimmora’s relationship to terrastalizing is a lead for that Sada/Turo diary entry-the Violet dex suggests that they are related, it’s eyes are the ones on the tera jewels, it’s Geeta’s signature Pokémon, it’s found in Area Zero, and it matches the description. Whether or not it’s Glimmora itself, or just related to it, idk.

I think Quaxly line is the standard form in the region it came from. Quaquaval seems to be inspired by "Carnaval". Also, Skeledirge seems to be inspired by Día de los Muertos. I think Meowscarada might be inspired by some holiday, but I have no idea which one, probably from either Iberian Peninsula or from another colony.

How crazy would it be if the Terastal phenomenon was caused by Paradox Cryogonal lol

I thought the secret tera Pokémon was just Glimmora because of the “hexagonal shell” & they are also used to get the TM for Tera blast… Maybe the secret legendary is a paradox form? Or variant like Diancie is to Carbink? 🤷

You forgot to mention that arven shows us a picture of the third legendary though

For the last one, when Quaxly was first introduced, I immediately thought of Ducklet. But with the dex entry that makes sense in a way. Ducklet and Swana are geese-like pokemon, which migrate from season to season. I wonder if Swana just migrated from unova, and had a ton of kids who looked slightly different, and the line went on. Plus, I assume that it stays fairly warm in Spain all year round, so then Swana never thought to leave, and evolved into Pokémon more suitable for full time living in the environment.

2:46 that's not totally true, in the glimmora dex in pokemon violet says "it's petals are made of crystallized poison energy, it has recently became evident that it's petals resembe tera crystals" i think that this secret pokemon may be the mysterious pokemon in the last page of the scarlet/violet book, and just like koraidon/miraidon is some kind of paradox Cyclizar, it may be a paradox glimmora

We’re almost definitely going to encounter that first one at some point in a DLC. Personally hoping it’s a Dragon/Rock-type which would be perfectly fitting with the aesthetic and effect of Terastalization.

Glimmora could fit (though not 6 letters) for the origin of terastilizing. Per violet pokedex: "Glimmora's petals are made of crystallized poison energy. It has recently become evident that these petals resemble Tera Jewels."

I will also point out that in the postgame Arven questline, you gain access to the Scarlet or Violet Book, and in it-specifically pointed out in the cutscene where you gain access to the book in fact-is another entry that appears to be about the first ‘mon you mentioned. Similar blocks of redacted text, though of seemingly random letters in the text, not the name itself as the author of the book makes no attempt to name it, accompanying an illustration of some kind of disk covered in hexagonal tiles with a decoration that could be interpreted as a tera crown.

For Greavard, it's evolution, Houndstone in the violet pokedex also says this "A lovingly mourned Pokémon was reborn as Houndstone. It doesn't like anyone touching the protuberance atop its head."

For the quaxly thing, a regional variant is a neat thing to think about. But as far back as Red and Blue the starters have been non-native to their regions. Some of the games, until the remakes (Fire Red and Leaf Green), make some mention of the starters being sent from "a friend/colleague" as an explanation as to why you can't catch them in the region you get them. Some games, notably remakes of older gens, forego this and sprinkle in the starters on some random route so that they can be acquired more easily. I wouldn't be surprised if Sprigatito and Fueccoco were from another region despite their dex entries not mentioning it. I feel the tidbit about Quaxly migrating over has to do with the fact many birds migrate for the winter/summer. It'd make sense for some to just settle or be caught in the regions they migrate to. I also think the first secret pokemon is actually going to be a variant of Zygarde. It is known for it's hexagonal cells, and has been shown to be in multiple forms depending on how many of it's cells have been gathered. If we accept this to be the case it would also make sense for the hexagonal crystals on the tera-crowns to be this speculative new zygarde form's cells. Yes, incomplete zygarde is known to be serpentine or canine but whose to say a new variant of it wouldn't be similar to a tortoise. In terms of the "six letter name" it could just be they used six "redacted" boxes to give themselves an out or obfuscate the pokemon's name. I believe it's the same number of boxes in each language that censors the name but I cannot check at current, it'd be interesting to look into the Japanese version and other language settings of the game to see how this one is spoken of. They could also use a renamed variant of Zygarde to fit the six letter name if they wanted to and, given what they did with Wigglet and Toedscool, I could see them calling it a new/different pokemon. In terms of the Varoom, I'd be interested to see what Pokemon they'd use to animate an inanimate scrapped engine. I also think it's good to temper expectations as if they ever did show what pokemon was the reason for its birth it could be an existing one. Saying "an unknown poison pokemon" could just mean that it's known a poison pokemon entered the scrapped engine and created Varooms but which one did so is the part that is unknown. If we go with this theory I'd say it could be part of the Gastly line, as they are poison pokemon and being a ghost as well they could realistically posses an inanimate object, potentially leading to the creation of a new pokemon species. These kinds of videos are super interesting, and even though I might sound like I'm attempting to counter your points I'm not, I'm simply offering alternate explanations as this video got me thinking about neat ways older pokemon could be reintroduced.

I thought for sure there would be mention of the unknown, monstrous pokemon that messed Arven's Mabosstiff. While it can be assumed that it was a paradox pokemon given the location, there is no explanation of which one it may have been (if any of them).

The first one was revealed as the Cover Pokémon for the Indigo Disk DLC

We do have confirmation of a DLC thanks to the knowledge that a Paradox Virizion & Suicune exist, so there's the potential it may act as the DLC legendary also there's a keyword in that dex entry "inspirited"...so the poison-type is probably a ghost-type as well

I also thought that the dark type dog Pokémon was going to be a punk chihuahua that evolved into a more demonic looking greyhound Pokémon instead of maschiff and mabosstiff, because the latter two don’t really look like dark type dogs to me

I'm pretty sure Glimmora is the source of Terastal phenomenon. It's Violet Pokédex entry even mentions it looks like a Tera crystal. My theory is that the Tera Orb is actually what it looks like a sort of Poké Ball that is stealing energy from a trapped Glimmora hence why the Tera crystal looks so angry.

I love the Vroom line. Hope to see that origin poison type in the future!

if you go to the school library you can find a copy of the scarlet or violet book that arven uses, and at the very end the researcher on the expedition says he felt possessed and doesn't remember writing part of it even though it is his handwriting. Part of it is a sketch of the hexagon shell pokemon that you have as the first secret pokemon. You might want to go look at that entry to see what he says and look at the messy sketch of it.

Just to let everyone know in case they didn’t you can find a copy of the scarlet/violet book in the school in mesagosa city inside of the book there is an art depiction of a strange mix of the legendary dogs from gen 2 that are fused together

What's kinda interesting to me is that Quaxxly and Mew's regions of origin seem to be pretty close together geographically, since both Pokemon seem to come from South American based regions.

The origin of the terrastallizing phenomenon is the Pokémon Terapagos, it’s Pokédex number is 1024

I think Greavard was an error, or insider retcon, something. Cause reading Greavards flavor text tells you that the dog Pokémon requires isolation from human interaction. Houndstone’s flavor text on the other hand states it’s reborn from a “lovingly mourned Pokémon”. Can someone help me out here cause from the games standpoint they are a direct evolution, but the lore implies that in order for Greavard to exist in the first place, it’s requirement for evolution is impossible? Some kinda Pokémon catch 22.

The first is just the dlc pokemon

Ive been wanting the pokemon thats responsible for the tera phenomenon to be the original form of kyurem. It would be so perfect, gen 5 remakes should be coming this gen, kyurem has 6 letters, kyurem's form in bw is a "shell" of its former self, and ice and crystals are similar being clear and being known to form cool patterns. Just wishful thinking, but it'd be so cool if it did happen

The first Pokemon is shown in a drawing in the Scarlet/Violet Book in the Acadamie's library. It's on the last page

You also see a potential sketch of the Terastal Pokémon in the Scarlet/Violet book found in the library at the school

If quacksly migrated and scarlet and violet is based on both portugal and spain, I think his evolution would probably be an awesome reference to brazil and samba. His attire is also very similar to the ones used in traditional brazilian dancing.

the Quaxly bit is very interesting but, as a brazilian, i think what they meant by "distant lands" could be a reference to the historical relation between brazil and portugal/spain... Quaquaval is clearly a reference to our Carnaval Dancers and that might why they reference as a distant land

There is an actual drawing of the hexagon shell pokemo. It is in the scarlet book, post game, when pepper shows you the page

At some point your shown a page of the scarlet book, and I remember reading about a round pokemon with the hexagonal plates, I don't remember when but I know we've been shown a drawing of it, although I doubt it's a very good one...

I have to say, that mabostiff storyline was the best of the initial three. It showed that Pokemon can be hurt in ways a trip to the local deus ex machina pokemon centre can't fix. The whole game had surprisingly mature story elements dealing with themes not touched by any of the previous games. I thoroughly enjoyed my time in Violet and look forward to starting a scarlet run.

That first one is probably the orb legendary that is seen in the scarlet/violet book alongside the Suicune/Virizion paradox forms.

The Varoom idea kinda sounds like when cats hide near the engine to keep warm, horror stories about not warning them before starting your car in the winter. Poison cat pokemon?

You can read the VIOLET book in the entrance hall of the school! It is full of lore about the terastalizing Pokemon!!! Go read it!

I hope DLC takes us through the Time Machine

Thank god you've talked about this.. The first research lab journal was driving me crazy and noones talking about it othe than you lol.

You need to go read the Scarlet/Violet Book found within the school entrance hall - it hints towards the Terastal legendary AND two new paradox Pokémon :)

I think Quaxly might have originated in Unova because it's from a 'distant land ' and since its the only Paldea starter with a non-Spanish inspired name. Something more farfetched is that it's just a Ducklett variant but I highly doubt it.

Theory: Quaxley doesn't have a "regional variant" but is an off-shoot of Duckley from Uvona, much like the Wiglett/Diglett relationship

What if the pokemon inside of Varoom is a Quilfish, making Revaroom's possibly an Overquil?

In the scarlet/violet book there is a drawing of that pokemon and some extra text with some blank letters (that are easy to figure out) But the blank spaces dont actally fit the missing letters so the pokemon does not has to be 6 lettered Btw, the pokemon cry that can be heard while terastalizing may be the cry of that origin pokemon

If you look at the violet (or I assume scarlet) book in entrance hall you actually can see a diagram of the first “origin of terastilization” Pokémon under the chapter titled “A ___isk P__é__n” which gives a slight description of the Pokémon with several blank characters within the chapter. Most words aside from the Pokémon’s name can be inferred but we know that the Pokémon was described as a word ending in “isk” that starts with a consonant.

would like to point out the first secret pokemon mentioned is ALSO referenced in the Scarlet/Violet Book that you can read in the library, with a whole lore page about it written by Heath

For the Maschief-Greavard connection, I think the main reason that the pokedex wouldn't specify that the dead dog pokemon was Maschief is because there's no way to prove it for certain, since it explicitly states the dead pokemon never met a human. Considering how difficult it is to avoid getting noticed by pokemon, it'd be next to impossible to monitor a Maschief until it died and became a Greavard without getting noticed.

Varoom has a few points in its dex entry that quickly narrow down its prime candidate, if you look closely. While the original Pokémon being a poison type doesn’t narrow things down by itself. The fact that it “inspirited” an engine, is the key to narrowing it down. You could take that as meaning a Ghost/Poison type is the prime candidate. In fact, we have one that appears in the region. Ghastly! A Gaseous entity that could have possessed an engine and perhaps burned its own fumes as the engine started and causing it to become infused, or rather “inspirited” into the engine. Loosing its ghost typing in the process!

Quaxly is probably from Brazil, given Quaquaval's dex entry and inspiration on Brazilian carnanal and Samba

I think that greavard was originally a herdier and houndstone was a stoutland as they both share the sand rush ability and a similar size.

The Terastal Pokémon is Deoxys. Deoxys is an Alien whose name is 6 Characters long. The Gem that composes the currently known Deoxys may have originated from this massive Gem here.

TERASTALLIZING WAS DISCOVERED BEFORE THE PROFESSORS!! In the books there is a chapter where the author Heath describes going into a sleep and waking up with the picture on the left page. This page literally shows how Terastallizing works. The Hexagonal gem inside the Tera Orb amplifies a sort of light energy around the pokemon allowing it to Terastallize. The Professors grew up with this book, that's how they were able to invent the Tera Orb. They read about the mysterious Disk Pokemon their entire lives wondering, now we're wondering when the DLC it shows up in will come out...bummer. But at least Area Zero was a fun and beautiful experience, and it's theme hits hard.

FYI there’s a partial picture of the hexagon Pokémon in a book shown by arven at the school after you beat the game

You know, if you actually go back to school, in the main hall is a copy of the Scarlet/Violet Book and it'll actually show an image of the said "mysterious"/"secret" Pokemon, along with another one depending on the version of the game you're playing. One is basically all of the legendary dogs meshed and put together, and the other one is the swords of justice mons meshed together into one mon. Just in case you guys missed it. The text and context details really help if you're spending time taking your classes and getting to know your professor, especially the History Professor.

okay the quaxly being from another region just makes me think of like, the next Legends game having quaxly as one of its starters. 👀

A Pokémon with a shell could be a turtle, tortoise, beetle, snail, armadillo, mollusk or a crustation. maybe some other animal.

you know when the pokedex says a dog pokemon could be any dog pokemon like growlith, rockruff or even riolu

All starters seem to come from another region than their "home" one, since you can never actually catch them in the region that features them (minus the Let's Go! games), so it doesn't seem out of the realms of possibility that it's from somewhere not far from Paldea, but closer to it than any other major region. Like, I could be misremembering, but weren't Charmanders from a small set of volcanic islands close to Kanto but not technically in Kanto? Could be wrong, but thought I remember reading that somewhere. I think a likely candidate for Varoom would be some kind of shellfish Pokemon, something akin to a hermit crab or some other crustacean or sea creature that are know to find new things for shells. The concept that it looked for a new shell and then crawled into the engine then got stuck and the weight of the thing was too much for it to move could fit a potential origin. Maybe in keeping with your theory Hoops it could have been what I believe are classified as "argonaut octopus'" which are basically octopuses with shells.

from RT's stream we saw some books on the ancient terastralize pokemon in the library. i can't recall exactly but there was even a sketch of it somewhere.

One of the history books in the school has a sketch of the armor of the terastilizing Pokémon, or the Pokémon itself

I think the source of the terastallizing phenomenon is a mythical Pokémon that is being released in an event or DLC

The song playing is "Mount Lanakila" by GlitchxCity

I think we also have a visual about the first pokemon you mentioned! In the pages of the Violet book in the Academy, there is a chapter called (probably) ''A Disk Pokemon''. Several of the letters in the text are omitted in the same way they are omitted in the professors diary, and the image shows a ball-like pokemon (probably it's shell) comprised of hexagonal plates!

You can see a sketch of the Terastral pokemon and get a bit more lore on it in the Violet Book/Scarlet Book. You can find the book on the first floor of the Entrance Hall of the school. It also classifies it as the Disk Pokemon

Another thing about the first secret pokemon that might be relevant is that in the scarlet/violet book there is a segment that refers to a pokemon that was dubbed the "disk pokemon" that looks like it has a hexagonal pattern on it similar to what was described in the labs and has never actually been seen in game outside of the picture in the book. I'm not 100% sure if that entry and what you described are conected, but I do believe that they are.

The first one is known as the disk pokemon, and its entry is located in the scarlet/violet book with some letters blanked out. You can find it after completing post game content after talking to arven and reading the book

I think Varoom poison pokemon origin may be Gastly: ghost pokémon are known to possess people and object both in anime /lore and as a game mechanic (Rotom), so a dual type ghost-poison would be the perfect candidate. In this case, the actual form of Varoom would not have anything to do with the actual "possessor" Pokémon (that is simply a mass of gas) and would instead depend only on the engine form.

With the first Pokemon you can see a picture of It just enter the academy go right and between the books there should be the Scarlet or Violet book you can see all the Pages,a imaginary Pokemon and the terastal Pokemon but the text its filled with White cubes,censored

For the first one Im surprised you didnt mention that its also talked about in the Scarlet/Violet Book Arvin carries around. You can read that book in full in the school library and the entry in question is accompanied by a wild illustration.

In the postgame, (in violet) you can go to uva academy and talk to arven. He will then show you the copy of a violet book, and it has the image of a mysterious hexagonal pokemon. However some of the parts of the book are "smuged in inc". You can still see a drawing however

Don’t forget the possible Suicune Paradox and possible Virizion Paradox forms that are only seen in the Scarlet Book and Violet Book respectively. The same book that shows the secret Pokémon that originated the gimmick of these games.

The first Pokémon was also mentioned in the last page in the scarlet/violet book located in the academy’s entrance hall.

10:39 Quaxly being named Ru Paul got me distracted lol

I guess will ignore the fact the hexagone “origin of tera forms” Pokémon is directly referenced in the scarlet/violet book replica in the library with a sketch of it

a few pokemon have the "what could it really be?" and we may never get that closure vibe like Varoom. Mimikyu, and the evolved form of that dung beetle thing.

My head-cannon is that Varoom's origin is a nod to the Haunter+pokeball=Voltorb theory. I know the eyes don't match, but the Gastly line IS Poison secondarily and as ghosts would possess the ability to "possess" things.

Personally, I believe the Pokémon that is the origin of the Terastilization phenomenon is already in the game, that being Glimmora. Though it doesn't match exactly the description in the book, there is a pokedex entry that seems to imply the connection, stating that " It has recently become evident that these petals resemble Tera Jewels." Not only that, but the eyes on Glimmora are almost identical to the ones that appear on the crowns of Terastalized Pokémon, just more angry looking.
