The Collectors from The Owl House are genuinely the most underutilized and under-appreciated entities I've ever seen. They're cosmic gods characterized by implications and lore dumps. They travel planet to planet turning mortals into play things for shows, and when they get bored? They just leave and move on. They don't care about their atrocities, nor do they care about eachother. They trapped their own kin, the youngest of their collective, in a disk to rot on a planet they burned.
They saw the Titans and were too afraid of the potential that they held to ever consider peace. The Collectors burned the sky, boiled the sea, killed the titans, then convinced the populace to keep hunting for them. They left the Collector to waste his eternity as a plaything on a planet that they intended to have ridden of life. (While in the end they seemed to have actively created the Titan Hunters, this was probably well after the initial apocalypse they started had started to settle.)
The Collector doesn't even get a name, which kind of implies none of them do??? They're all faceless robbed cosmic beings that travel the stars, collecting life for their own entertainment. If we assume the tablet the Collector is trapped in is like, their usual method of containment, then they probably use them like TVs. The organism trapped inside projects as a powerless shadow that could then play out however they desire.
You could argue that's just a Collector thing, but I DO NOT agree. Everything tells us that they collect creatures, and if it's not a Noah's ark situation, then it has to be entertainment. Plus with things like the Archive (which Collector talks about like it's just a thing that exists, implying he didn't really make the concept of it) or just the puppetification and his general power set... yeah, it just leans to the idea that they collect for sport and pleasure.
Also it's interesting how they kind of parallel humans and witches??? Think about it, they're two powerful races from other worlds. When they meet, it's not immediately horrible, but when one finds out the other holds any potential power over them, they go on the offensive. The Collectors basically just pulled off their Day of Unity, which also just makes Belos MORE interesting because he was doing what the Collectors would have wanted. He was doing what they did while lying to say it was for the Titan, who could SEE him doing all of this.
Also also the powerscaling is insane because to KILL an adult Titan is like, near impossible it seems. After thousands of years Papa T deadass just didn't die, he said no and his heart still beat. (though that wasn't really like, doing much? Since it wasn't like pumping blood or anything, it was just a piece of symbolism incarcerate) we know that at least modern day Boiling Isles rain can't hurt someone with the Titan's powers, but also it's been THOUSANDS of years since the Collectors even DID that. The fucking salty ocean is boiling. THE SALT WATER IS STILL BOILING!!! They turned this planet into a damn star just to try to cook the Titans off, then left the Collector there with an unhinged book of their atrocities and his "failures".
I've been thinking about them a lot recently, happy to put some of it into text lol. I PRAY we see them, I NEED more. They're literally cosmic horror, please Dana I beg you.
