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.
The gods might show their protection in various ways. For example, they could directly intervene in battles Percy is in, using their divine powers to shield him from harm. They might also send him signs or omens to guide him away from danger.
Their shared experiences play a big role. They've been through so much together, like countless battles and adventures. Percy has seen Annabeth in tough situations and he knows how strong she is, but also how vulnerable. So he feels the need to protect her. For instance, they might have had a close call in a previous adventure where Annabeth was nearly killed, and that memory makes Percy extra vigilant.
In some cases, Percy might be protective in more emotional ways. If someone were to say something mean or critical about Annabeth in the fanfiction, Percy would be quick to defend her. He would stand up for her and not let anyone undermine her confidence or abilities.
Yes, in some fanfictions, Percy is often reimagined as the king of the gods. Writers like to play with the traditional mythology and give Percy this exalted status for creative and interesting storylines.
Aphrodite could also be one of the spying gods. Since she loves meddling in love affairs, and Percy and Annabeth's relationship is quite famous among the demigods. She might be spying to see how their relationship develops and perhaps add a little nudge here and there if she feels like it.
I think 'the gods spy on percy fanfiction' would likely involve the gods using their various powers to keep an eye on Percy. They could be using magic, or enlisting the help of other mythical creatures. This fanfiction might also show how Percy's friends get involved when they discover the spying, and the resulting conflicts or alliances.
Well, it could be about Percy's adventures and interactions with the gods in a rather unique or interesting way. Maybe it shows some new relationships or challenges Percy faces when dealing with the gods.
Well, one way Percy could be betrayed by the gods in fanfiction is if they break their promises to him. He has done a great deal for the gods, like saving Olympus. But if they don't fulfill their end of the bargain, like granting him certain protections or rewards, that would be a huge betrayal. Another way is if the gods side with his enemies for some political or self - serving reason, leaving Percy out in the cold.
Well, maybe it's because fanfiction can take the story in all kinds of wild directions. The gods in the Percy Jackson world are used to a certain order and set of rules. Fanfiction might rewrite their fates or show them in unflattering or unexpected ways that they can't control, so they're scared.
