Summary
Shouto shouldn’t have been surprised at the course of events. It was almost the norm for some major villain to pop up every few months--if not every month--and cause a large scale incident that would ignite a media storm. But here they are. Really, none of them should have been surprised when aliens are raining from the sky, ancient gods are fighting, and a man has been (kinda) resurrected from an icy death. Strange portals bringing strangers from strange worlds means life just got a whole lot more interesting for everyone.
And maybe a lesson or two about what it means to be a hero.
**First fic on AO3. Just playing with some ideas with this crossover, so canon is kinda flexible.

Summary
“We embark to Natlan tomorrow,” the Captain explains slowly, in that deep, measured voice. “However, I have just received an unfortunate notice: my lieutenant has been infected with Abyssal Corrosion Syndrome. He is important to my plans, and I am lacking in a suitable replacement of similar talent and ability.”
“Tartaglia is needed for Project Stuzha,” The Rooster argues, shaking his head vigorously: the long feather pinned to his hat trembles along.
—
In which Tartaglia, months after a full recovery from the Fontaine Debacle, enters the grand battlefield of Natlan as a stand-in for the Captain's ill lieutenant, and this somehow makes everything better and worse.

Summary
Poseidon has, at this point, broken just about every rule in the book. If his younger brother were just a little more observant, he would be in untold amounts of trouble. It's just that if any traits of Poseidon's can be said to be admirable, it's that he is a very devoted father. Yes, he has countless children by countless different women (and men, too). But every single one of those countless children is his, wholly and completely, forever. So when little Percy Jackson is born, Poseidon's first child in decades, the mighty king of the seas finds himself absolutely smitten with this tiny newborn demigod. He knows the rules, knows the risks. He just… he can't bring himself to leave this time.
So, he doesn't. He stays.

Summary
The wizarding world did not tend to be particularly religious in a way most muggles would comprehend, but that is not to say they don’t believe in the gods. On the contrary, in fact, you’d be hard pressed to find a pureblood that didn’t follow the ancient Olympian deities.
Percy Jackson had always looked like his father. With his rising divinity, it’s no wonder the wizards tended to mistake him for a god himself. (Though their guess may not be as far off as one would be led to believe.)
Or: The Percy Jackson and Harry Potter crossover nobody asked for, featuring divine puberty, a rarepair, and too much angst for my own good

Summary
Percy Jackson is done.
Done with quests. Done with prophecies. Done with gods who treat survival like a favour and freedom like a luxury.
So he runs.
Gotham City is far enough from Olympus that even the gods hesitate to look too closely and strange enough that Percy can almost convince himself he’s just another student trying to get a degree and stay out of trouble.
It doesn’t help that he can’t really smell properly anymore. Tartarus made sure of that. Instincts come in broken pieces now, like someone handed him a map with half the ink missing and expected him to navigate anyway.
Which makes Gotham extremely confusing.
Because people keep… doing things.
Standing too close. Touching his shoulder. Leaving jackets. Looking at him like he belongs somewhere near them.
And occasionally - very occasionally - someone tries to scent-mark him.
With ascension looming over his shoulder, three very confusing alphas, and one cute clone that he knows he shouldn’t feel anything for, Percy’s plans to stay out of trouble start falling apart around him.
Percy came to Gotham to disappear.
Gotham has other plans for him.Series

Summary
Despite what most people thought, Percy’s first title wasn’t ‘son of Poseidon’ or ‘defeater of the minotaur’.
No, his very first title was Perseus Odysseus Wayne, Prince of Gotham.
Gotham’s press went wild the day he was born –partially, because his father was only eighteen when he had him. While Gotham obviously wasn’t very conservative, it was still quite the scandal. Especially given that Percy’s other parent was completely unknown.
His face was plastered across every headline for three weeks and would be a frequent part of the news for many years to follow. Being the only child of Bruce Wayne, the sole Wayne family heir, was a very big deal.
Not that Percy really cared.
- - -
Or in a universe where Bruce Wayne, a man with clear sight blessed by Nemesis, fell in love with Poseidon, who was being compelled to have a child by the fates, have a son together, Percy Jackson's life ends up just a little different. Not enough to change the timeline, but enough to change his childhood and eventually, his life post-war. Especially when he discovers his dead brother is alive and subsequently returns to Gotham.
