Yes, there are quite a few. You can check fanfiction websites like Archive of Our Own. Some of these fanfics might explore Percy coming back as undead in really interesting ways, like having unique powers or facing different challenges compared to when he was alive.
Well, often there's the theme of identity. Percy has to figure out who he is now that he's undead. There's also the theme of acceptance, both from himself and from those around him. And a lot of times, the fanfics explore how his new state affects his connection to the gods and his demigod powers.
No. Percy Jackson is an original fictional series. Although it uses Greek mythology as its base, it has created a completely new world, characters, and storylines. Fanfiction usually implies building upon an existing work in a more derivative way, often by fans rather than the original creator. 'Percy Jackson' was created by Rick Riordan as an original concept.
In Percy Jackson fanfiction, families can be depicted in various ways. Some might show Percy's family having new and unexpected adventures together. For example, his mom could discover a new magical ability that she uses to protect the family from an ancient threat. Another idea could be that Percy's half - brother Tyson becomes a key figure in protecting the family from monsters that target them specifically because of Percy's fame among the demigods.
One idea for a Percy Jackson famous singer fanfiction could be that a famous singer is actually a demigod in disguise. Maybe they use their music as a form of magic or to communicate with other demigods secretly. For example, their lyrics could hold hidden messages about upcoming quests or threats to the demigod community.

Since he has a connection to the water element, blood being a liquid could potentially be manipulated in a way similar to how he controls water. Maybe he can sense the water content in blood and use his will to move or influence it.
Well, sometimes in fanfiction, his brother might be a mortal who discovers his demigod heritage later. This could add an interesting twist to the story as he has to adapt to the world of gods and monsters. Or it could be a long - lost half - brother from a different camp, like a son of Poseidon from another part of the world who was hidden away for some reason.
Well, in some fanfictions, Percy might control ice through a new power bestowed upon him by some mysterious god or entity. Maybe he discovers he has the ability during a quest when he's in a really cold and magical place.

And her relationships with the gods are also unique. Instead of the typical male bravado, she uses her wits and charm to get through tough situations.
