I would throw in a "Hello internet!" Joke but honestly let's get right to the point.

Part 1: What pokemon am i even talking about?

For those unaware (And if so then spoilers inbound. There's a page in the scarlet/violet book that shows a undescribable pokemon. And it stands out because it's one of the only pages that has multiple letters blocked out.

Now it's hard to translate what it says but i think i've narrowed it down to say this

"A disk pokemon? While separated from the research team in the craters depths i found a strange...entity. Whether it was a pokemon or even alive at all i know not. It bore a shell with layers of overlapping hexagons and gleamed brighter still than a gemstone. Viewed as a whole it resembled a mysterious (No idea what word here) Disk.

Now there's alot to unpack there. And we haven't even started on the image. However i think that this creature is the cause of the great crater of paldea. Not only that but i believe this is the "great treasure" that's in the bottom of paldea. A dangerous creature slowly regaining it's previous power after crashing into earth.

Now why would i think something like this? Well it all boils down to area zero. So let's start there shall we?

Part 2 Area zero and the great crater.

So right of the bat look at this image of the crater of paldea.

Throughout the game were just told that the crater just "Showed up" And that's it. There's rumours of treasure sure but nothing else. But look how big the crater is! That doesn't just generate in a reigon randomly! However it WOULD make sense if say a billion years ago a meteor struck the paldea reigon. Killing the pokemon we now know as paradox pokemon of the past and then leaving a massive crater in the middle of paldea. That would explain it wouldn't it? But wait a minute i was saying that the book creature was the cause of the crater why am i saying that a meteor caused it?

Well it's kinda simple: The meteor IS that book creature. It crashed into the paldea reigon from space.

But how could i claim that this creature came from space? Well uh.. I can't. However i can show you a weird coincidence! Look at the image of that creature again. Notice anything weird? Like i don't know.. The planets and stars shown next to the creature? Weird coincidence and even weirder that it got into the finished game. But hey i'm sure it's nothing! Time to look for more flaws in this theory!

You may notice that the creature is a massive sphere. While the crater on the map is kinda jagged. Not really resembling a circle. And yeah that's a flaw in the theory that i can't really disprove. However i can show official artwork of the crater!

Oh look! A circle! How convenient!

Anyway there's one final part i want to cover that at least in my opinion solidifies this theory. The terastal phenomenon.

(I was gonna have this as a third part then realised how short it was)

So the book describes the creature as having multiple hexagons around it's body. Now why does this sound famliar? Oh right terastilizing. It's tricky to make out in the games but i think there is in fact a hexagon pattern around the pokemons body. Add that and the fact that the terastilizing came from area zero and suddenly things are starting to make sense!

This creature is MADE out of terastal crystals. And when it crashed into paldea. It scattered those crystals around the crater it had just created. Waiting for sada/turo to find them and create the tera orb.

And uh i think that's the theory! I can't wait to be proved completely wrong lmao. Hope you liked it!
