Well, if Percy Jackson visited Asgard, he'd probably be in for a wild ride. His water powers would be quite a novelty there. Maybe the Asgardians would mistake him for some sort of new kind of magic user. He might get into all sorts of adventures, like trying to compete in their warrior games or getting caught up in a plot by Loki. Percy would also be really curious about their technology and magic that's so different from what he's used to in the demigod world.
Percy's water - controlling abilities would be unique in Asgard. He could use it for defense and offense. For example, he could create water shields or water whips to fight against enemies. His ability to breathe underwater might not be as useful in Asgard directly, but it could come in handy if there are any underwater areas or if he has to deal with water - based magic there.
He'd have to learn the new rules. Percy is used to the Greek pantheon's way of doing things, but in Asgard, it's a whole different ballgame. He'd probably start by observing how the Norse gods and their followers interact. And he might use his charm, which has served him well in the Greek world, to make friends among the Norse.
If Percy Jackson was in Asgard, it could be a total chaos. He'd be constantly comparing the Norse world to his own Greek one. His powers related to water might not be as useful in Asgard as they are in his usual realm. However, his combat skills and his ability to think on his feet could still come in handy. He might also have some interesting interactions with Thor, perhaps getting into a friendly competition over who can fight better or something like that.
A possible plot could be Percy discovering his Asgardian heritage and being taken to Asgard. There, he has to prove himself worthy among the Asgardians while also trying to figure out how his demigod powers interact with his new - found Asgardian abilities.
Yes, there are likely some out there. Fanfiction is a vast world, and crossovers between different fictional universes like 'Harry Potter' and the concept of 'Prince of Asgard' are not uncommon. You can start your search on popular fanfiction websites such as Archive of Our Own or FanFiction.net.
