I've spent an unhealthy amount of time digging through that tag. Honestly, if we're talking series, there's a clear standout: 'The Tide That Pulls You Under' by Kratosa. It's an OC-centric saga about a daughter of Poseidon who washes up in the modern era after being trapped in a sunken temple for centuries. The author nails the loneliness of being a living relic and the overwhelming sensory input of a world that's moved on.
What makes it work is how the mythology is woven in—it's less about Percy's New York and more about the ancient, terrifying weight of the sea gods. The series explores Poseidon's domain beyond just water, touching on storms, earthquakes, and even the deep-sea trenches. The writing can get slow, but the payoff in book three, when she confronts her half-siblings from other pantheons, is wild. Just be ready for some heavy world-building in the early chapters.
I stumbled onto it after exhausting most Triton-centric fics, and it rekindled my interest in that whole side of the Riordanverse. The character dynamics with a jaded, older Chiron are a highlight.

Frankly, the whole Poseidon/Odysseus pairing always struck me as more of a fringe 'could be read as' ship than a primary focus in most fics. You're not gonna find a dedicated tag bursting with content anywhere. The best material is usually buried inside longer 'Odyssey' retellings or god/human interaction stories on Archive of Our Own. I've had luck searching 'Poseidon & Odysseus' or 'Poseidon/Odysseus' there, filtering by the 'The Odyssey - Homer' fandom.
A lot of it ends up being one-sided divine obsession or wrath-tinged with potential, rather than outright romance. I remember one called 'Salt and Strife' that explored their dynamic through centuries—really played with the cyclical nature of myth. The characterization matters most; you want a Poseidon who's more than just an angry sea god, and an Odysseus who isn't just a clever victim. The scarcity means when you find a good one, it's worth savoring, even if it's just a few thousand words.
Honestly, most of my finds have been through wandering the 'Ancient Greek Religion & Lore' tag on AO3 and getting lucky. Tumblr sometimes has metas or drabbles, but it's even more fragmented there. It's a ship for the patient digger, not the instant-gratification scroller.

Actually, one of the weirdest crossovers I've stumbled upon wasn't even in the 'Percy Jackson' tag, it was buried in a Norse mythology fandom. Someone wrote a fic where Triton's daughter—yeah, Poseidon's son, so I guess she still counts—gets stranded in the Nine Realms after a storm. It wasn't a typical power showdown. The whole premise hinged on her trying to explain a bureaucratic, semi-democratic underwater kingdom to Thor, who just couldn't wrap his head around the concept of oceanic zoning laws and merfolk senates. The comedy came from cultural misunderstandings, not fights.
That got me thinking about other pantheons. Egyptian gods seem like an obvious mix, given the shared water domain with the Nile, but I've read a couple where a daughter of Poseidon tries to bargain with Sobek and it's just a mess of competing territorial instincts. There's a surprising amount of stuff blending with Slavic mythology too, which feels fresh. Vasilisa meets a sea witch, that kind of vibe.
The less obvious but more memorable ones for me are the quiet crossovers. I read one where a Poseidon kid ended up in the world of 'American Gods', just a background character trying to get a bus ticket, and her divine signature caused all this low-key chaos with the old gods hiding in the modern world. It was more about atmosphere and existential dread than epic plots, which really stuck.

I’ve got this one saved. The fanfiction that immediately jumps to mind is ‘Saltwater and Steel’ over on AO3. It’s a Percy Jackson AU where Triton actually raises a demigod daughter from childhood. The character growth isn’t just about mastering powers—though watching her learn to manipulate pressure in the deep ocean is terrifyingly cool. It’ Fairly slow, focusing on her trying to reconcile the brutal, political world of the Merfolk court with the human side she inherits from her mother. She starts off naive, almost brittle, and her development into someone who can navigate both worlds without losing herself feels earned, not rushed.
What I appreciate is that the growth isn’t isolated. Triton’s own arc as a reluctant father figure mirrors hers, and their dynamic shifts from cold obligation to something fiercely protective. The author doesn’t shy away from the darker implications of being a pawn in godly games, either. By the latest chapter, her strength feels like a choice, not just a power-up.

The standard suggestion is usually Archive of Our Own, but I actually had better luck with FanFiction.net for this specific niche a few years back. That site's search filters are clunky, but if you navigate to the 'Percy Jackson and the Olympians' category and sort by reviews or favorites, a lot of the older, really foundational daughter of Poseidon fics float to the top.
A surprising number feature romantic subplots with Triton or other sea deities, which makes a weird amount of sense given the family drama potential. Sometimes you can find crossover gems with 'Harry Potter' where she's paired with a Black family wizard, playing up the whole ancient, powerful bloodline angle. Just be prepared to sift; the quality varies wildly, and the characterization can shift from 'fierce and independent' to 'constantly needs saving' in a way that grates after a while.
My personal bookmark is a long-abandoned WIP called 'Salt and Silver' that did the Percy/OC daughter of Poseidon dynamic better than anything I've seen since.
