I had to think a lot about this not gonna lie. Because one thing about godly parents in PJO is that godly parents influence a child's personality quite a bit (which I personally don't like but whatever). And it's kind of limiting on what I could do. I think if I do actually write this it would be following the canon (simply because it's the easiest to do and I don't have to think a lot lmao). So I guess I could go over the cast and what I think their godly parents would be. (Part 1 because I've officially decided).
Percy - Now as for Percy I've been thinking about it as much I lowkey wanted to do Zeus!Percy I don't think I'm going to. I just grown to not like the idea. I think I'm just too attached to Percy being a son of Poseidon lol. I have been recently swayed by Hades, Nemesis, or Hephaestus as his godly parents for some reason.
Now I HAVE been thinking possibly doing like something based on this fanfic I read where Percy was the child of ALL of the big three kids cuz Sally slept w/ Zeus Poseidon and Hades but I don't think I'd do something that crazy. (I also thought about Orion and how he was made and eugh).
I'm so indecisive and it's lowkey showing.
I do have a slight HC I might use to make this work for my self indulgent reasons (godswap AUs are purely for my self indulgence borderline crazy stuff so). Anyways the HC is that the Jackson family is actually intensively connected to the godly world and pantheons (specifically Greek and like Aztec). So he just has a bunch of randomly godly bloodline from like everywhere. So maybe he's like Frank and has a godly gift from Hades.
Poseidon and Nemesis would be his two (mamma mia) godly parents, Nemesis appearing to a bitter Sally after Poseidon just- left. And maybe Percy is just a legacy of Hephaestus (demigod Sally??) and instead of Leo, Percy got his fire (thinking it would be a post Mt. Helens thing after seeing his grandson nearly die he decides to give him a gift and help him out.) That's also him slowly discovering Hades gift on Calypsos island (and possibly staying much longer than expected while he tries to figure out what the hell is going on).
Annabeth - Okay so for Annabeth I actually have two candidates: Apollo and Prometheus. Apollo is the God of Knowledge which makes since and I feel like her godly gift instead of it being a cap it would be like a special bow and arrow or something (not sure).
As for Prometheus, he's the Titan of Forethought and Fire (Kinda?). I feel like it would make the dynamic between Luke and her interesting especially when she gets claimed and everyone's wary of her because of her connections to the titans and Luke. Maybe her being able to see glimpses into the future (in certain situations, maybe only her own plans?) Nothing too ridiculous. Maybe she can only see possibilities or maybe only the forethought only applies to herself and can only applies to others the more she knows them.
Despite this I'm actually leaning towards Apollo (not because I want to make this as easy as possible for me to write). But I feel like Annabeth being shunned and people being wary of her doesn't fit her so I'm thinking Apollo (maybe having her Patron being Athena??)
Grover - Now this one on the other hand idk. Demeter!Grover sounded sort of cool but I'm not sure. I kind of wanted to give him a godly parent but I feel like it takes away from his whole Pan arc which was his main arc so now I'm not so sure. Might keep 'em a Satyr.
Luke - Now I actually got this from a poll of a post but Hades!Luke or Dionysus!Luke is definitely interesting. I feel like it would change the dynamic of Percy and Luke completely, especially hades. It would also require some tweaking of the prophecy which it would not be necessarily the next child of the eldest gods but just the one that fits the mold I guess? Noticing how it also fits the evil hades stereotype for his kid to be the bad guy lol. Hades possibly refraining from claiming him until maybe like right before his quest with a smug look on his face but Luke just ends up doing... nothing. And he's sort of pissed at Luke because "wdym you're not the child of prophecy??"
Ethan - Still going with Zeus for this. I really liked my Zeus!Ethan idea so I want to stick with it for sure (https://www.tumblr.com/juniorig0327/760067385645580289/zeuspercy-and-possible-siblings?source=share)
Nico (& Thalia because I don't really have any ideas for them yet) - Ah yes, Nico and Thalia. Now there's a few reasons I sorta don't have an idea for them.
One, they're godly parents are sort of dependent on Percy. Two, I feel like a huge part of their characters are being big three kids (unless i exploited the loophole in the prophecy and having the elder gods be The Big 3 + Demeter, Hera, Hestia + Aphrodite??)
Hypothetically if I did do that though I'd probably make Nico a child of Aphrodite with slight water affiliation or maybe have him embody the war-like epithet.
As for Thalia, I think if I kept Percy a son of Poseidon, Thalia would have to be a daughter of Zeus. The only other big three kid I could see her being is a Poseidon Kid to be honest.
That's it for my rambling (for now). Just uh, ignore all the other godswap posts maybe? (I kinda dont want to delete them).
Hopefully my last post for today (I've been saying that to myself alot today lmao).
