I Have Two Ideas On This:

I have two ideas on this:

One possibility is that Rose had been collecting a large amount of wishing stars in hopes of running experiments on them. It was known that wishing stars emit energy, so maybe he was trying to see if there was a way to use them as a renewable energy source. Eventually Rose would have accidentally stockpiled enough of what are literally pieces of eternatus' body for it to reconstruct itself. One moment it's a pile of wishing stars, the next they're glowing and clumping together untill poof: you now have one realy sickly looking god.

Another possibility focuses on how Rose owns the galar mines. If I understood the lore correctly, then the glowing gems all over the caves are used for fuel. Not only that, but considering how much time Bede spends hunting for wishing stars in the mines its more than likely there are a lot of them down there. Maybe while excavating a new tunnel the miners open up a sealed cavern with a hibernating Eternatus within. It would probably look similar to the cocoons of yeveltal and Xerneas. Something like that would get reported, so Rose would come to investigate.

Here’s a question I don’t think I’ve seen any theories on yet - just how did Rose even find Eternatus in the first place?

Ordered this lil guy on etsy from WubbieWorldShop, and just look at him! So cute!

!!! I have! So many ideas about that! I've actually been working on a concept drawing of what I think eternatus originally looked like. As for a possible lower stage of completion form, perhaps when eternatus first reformed it was extremely damaged? ie. cracks all over, broken ribs and spikes, etc.

You know what I have no self restraint so have this ramble I texted to a friend once:

Basically I head cannon that the eternatus you see in game is not complete, because

1) it doesn't have every wishing star and piece incorporated into it, and those are literally pieces of its body. Case in point; Sordward and Shielbert stealing enough wishing stars from Sonia's lab to not only forcfuly dynamax a large number of pokemon, but also drive one of the legendary wolves mad. That would take a lot of wishing stars.

2) it is skeletal, but then when it is eturnamaxed it is not all that skeletal. Perhaps an echo of its original apearance?

3) ok, but it's a SKELETON.

And 4) if you have watched it move in the poke camp, you may note it both moves like an eastern dragon and moves painfully slowly. Perhaps it is attempting to replicate how it used to move when it was whole, and it's sluggishness is due to moving via magic and sheer force of will instead of tendons and muscles.

This also leads into another theory that i have which is that when Eternatus eternamaxes it is attempting to use some form of last resort self defense mechanism (perhaps it could originally gigantamax itself?), but due to missing a large part of its body it goes horribly wrong, and eternatus essentialy turns inside out instead.

This could also give a lore reason for why you can't eternamax eternatus; it is physically excruciatingly painful for Eternatus, and it would be cruel to force them to.

As for why eternatus is broken, basically it got hit by a meteor that then dragged it to earth where it crash landed. Both the meteor impact and the crash landing led to eternatus' body shattering.

And so the reason behind the darkest day is our space dragon, already very startled by crash landing and being shattered, is then panicked by how humans respond to them ("reeeeeeeeee! Get the pitch forks!") So Eternatus tries to defend itself, accidentally eternamaxes for the first time, and is frightened even more by pokemon randomly gigantamaxing.

And no, you can't convince me that eternamax is at all normal for Eternatus.

1) it's triggered by OVERLOADING its core. You know, that thing that is most likely a mini star/powered by nuclear fusion (or possibly worse powered by something eldritch). That can't go well.

2) eternamax eternatus looks like its body has completely broken in ways that it shouldn't. The "hand" is actually its head TURNED INSIDE OUT, its spine has been pulled apart, its wings(? I honestly don't realy know if that's what they are) are floating around the spiral, and its claws are currently floating in a ring around its core.

Here’s a question I don’t think I’ve seen any theories on yet - just how did Rose even find Eternatus in the first place?

Me, last night: alright, I should go to bed soon-

My brain: worm on a string, but it's applin with spaghetti.

Me: ...

Applin on a spaghett

I regret n o t h i n g

So are we not going to talk about the fact that you can eat what is probably eternatus' flesh?
