I don't know who the author is. There's no information given to determine that.
I'm not entirely sure as it could be a very specific fanfiction. It might be about a character named Percy who has some sort of secret fame within the context of the fan - created story.
Well, it could mean that there is fanfiction related to Percy Jackson that has some sort of secret fame. Maybe it's a particular story or series of stories that fans know about and love, but it's not widely known in the general public. It could be that the fanfiction has a cult following within the Percy Jackson fan community.
I'm not sure of specific examples off the top of my head. But it could be fanfiction that delves deeply into the backstories of minor characters from the Percy Jackson series. Maybe a story that focuses on the early life of a demigod that was only briefly mentioned in the books.
There's no way to tell just from the title. It could be written by any fan who has an interest in Sakura - related stories.
Since it's a Naruto - based fanfiction, Naruto himself is likely to be one of the main characters. He's the protagonist of the original series, so he'll probably play a central role in this fanfic too. Sasuke might also be a main character as he has a significant relationship with Naruto.
The Olympian gods who feel threatened by Percy's secret god - like status could be the main antagonists. They might see him as a threat to their power and order.
Yes, it could be possible. In many fanfiction concepts, crossovers and hidden interests are common themes. Percy Jackson, with his world full of mythological elements, could secretly be a fan of wizardry. Maybe he's intrigued by the idea of magic that's different from his own demigod powers.
Yes, in a lot of fanfiction, Percy Jackson is depicted as secretly smart. Writers often show his intelligence in ways that might not be as obvious in the original books. For example, he could have a deep understanding of ancient Greek strategies that he uses to outwit his enemies in fan - created scenarios.
The 'famous Percy' could be a super - fan who has made a name for himself by creating amazing fan art of Percy. When Annabeth meets him, she is impressed by his creativity and how well he has captured Percy's likeness in his art.
Another possible main character could be a rival. A person who is always competing with Percy and who might use the discovery of her secret as a weapon against her. This would add a lot of conflict to the story.
