A fanfiction where Percy is given the task of training new demigods in a way that aligns with the gods' values. He could teach them about respect for the gods, as well as how to use their powers responsibly. This would be something the gods would want as it helps maintain order among the demigods.
Maybe a story where Percy has to go on a quest to retrieve an ancient artifact that was stolen from the gods. Along the way, he faces many challenges and overcomes them with his courage and the help of his friends. The gods would be pleased to see their lost item returned and Percy's loyalty to them.
One idea could be a fanfiction where Percy uses his powers in a new and unique way to solve a problem that the gods themselves are struggling with. For example, he might find a way to stop a magical plague that is affecting both mortals and immortals. This would show his value and ingenuity, which the gods might appreciate.
Chiron could also be a key figure in trying to save Percy. As the centaur trainer at Camp Half - Blood, he has a lot of knowledge and connections. He might try to negotiate with the gods on Percy's behalf or find some loophole in the gods' actions to free Percy.
Probably Poseidon, as he is Percy's father and has a vested interest in his son's well - being. Zeus might also be protective in some cases, despite their past differences, as Percy is a hero who often saves the world which benefits Zeus's realm as well.
Another idea is a love story where Percy falls in love with a minor god or goddess. This could involve them having to keep their relationship a secret from the other gods because it's forbidden. The story could explore the challenges they face in their relationship and how they deal with the jealousy and interference from other deities.
One idea could be Percy having to face a new and powerful enemy that even the other gods are afraid of. He has to use his unique skills and connections to defeat it.
One plot idea could be Fem Percy having to prove herself to the gods in a series of trials. Since she's female in this version, she might face different expectations and prejudices from the male - dominated pantheon. Another idea is a love story between Fem Percy and a god, like Apollo perhaps, and how their relationship is complicated by the power dynamics between mortals and immortals.
One idea could be Percy going on a quest to find a lost artifact that has the power to control the weather in the Olympian realm. This would put him in conflict with some of the gods who want to use it for their own purposes.
Well, perhaps Percy could use his knowledge of the gods' weaknesses to his advantage in the pranks. Like, knowing that Zeus is afraid of being overthrown, Percy could stage a fake 'demigod uprising' just to see Zeus's reaction. Or he could play a prank on Aphrodite by making all the statues in her temple look like really ugly versions of her. This would surely get a big reaction from the goddess of beauty.
Perhaps a fanfiction where the New Gods create a sort of competition for demigods. Percy enters this competition and discovers that there are rules he's not used to, and he has to use his wits and skills in new ways to win. And along the way, he makes some unexpected allies among the new gods.
Well, without reading the specific fanfiction, it's hard to say exactly who Percy is. But generally, in a 'champion of the gods' scenario, Percy would be a central figure. He might be a hero with unique powers, like being able to control certain elements or having superhuman strength. He could be a character who has to face various challenges and tasks on behalf of the gods, kind of like a chosen one in a fantasy story.
One great 'the gods raise percy fanfiction' story could be 'Percy's Divine Upbringing'. In it, Percy is raised by the gods in a way that gives him unique powers and a different perspective on his demigod life. It shows his struggles and growth under their tutelage.
