They might be quite amused. Percy's father Poseidon could find the different interpretations of his son's adventures interesting. Zeus might be a bit miffed if the fanfiction portrays him in a less than favorable light. Hades, on the other hand, could either be indifferent or intrigued by how the Underworld is depicted in the fan - made stories.
The Big Three reading 'The Lightning Thief' fanfiction would lead to a variety of reactions. Poseidon, being Percy's father, would probably have a sense of pride in seeing how popular Percy has become in the fanfiction world. He might also chuckle at some of the creative liberties taken with the story. Zeus, being the king of the gods, would likely be more critical. He might not like any fanfiction that undermines his authority or shows him in a negative light. Hades would have a more complex reaction. He is often misrepresented in the original stories as well, so he might be both intrigued and a bit frustrated with how he is portrayed in the fanfiction. In general, it would open up a whole new dimension for the Big Three to view their world as seen through the eyes of the fans.
Well, they might be really confused at first. The Avengers are from a world of superheroes and high - tech battles, while The Lightning Thief is all about Greek mythology in a modern world. Tony Stark would probably make a lot of sarcastic comments about the magic and monsters in the fanfiction. Thor might be interested in how the Greek gods are portrayed compared to his own Norse pantheon.
Well, they might be either amused or offended. Some gods could find the creative interpretations of their characters in the fanfiction quite entertaining. For example, if the fanfiction shows a different side of Percy Jackson that they hadn't considered before. However, other gods might be offended if the fanfiction portrays them in a negative or untrue light, like making Zeus look cowardly when in their view he is a powerful and fearless leader.
Well, if Apollo read 'The Lightning Thief' fanfiction, it would be quite the cross - cultural (in a sense of different fictional cultures) experience. He might start to question some of his own beliefs and roles if he saw how the modern - day fans had reimagined the concepts of gods and heroes. He could get really into it, trying to figure out how the rules of this new fictional world worked. Or he could simply scoff at it, thinking that the fanfiction writers had no real understanding of the true nature of divinity and heroism as he knew it. However, it could also open up new ideas for him, like new ways to interact with mortals or new forms of magic that he hadn't considered before. It all depends on how open - minded Apollo would be in this fictional scenario.
If Harry Potter read The Lightning Thief fanfiction, he'd likely be both fascinated and bewildered. Fascinated because it presents a whole new world with unique powers and characters like the demigods. However, he'd also be bewildered as the magic in Percy Jackson's world is based on Greek mythology which is very different from the magic he's used to at Hogwarts. He might start comparing the two magic systems and thinking about how they could interact if the two worlds collided. He might also wonder how the challenges faced by the demigods compare to his own battles against Voldemort.
They might be amused. The gods in 'The Lightning Thief' have their own personalities. If they read fanfic, they could find the different interpretations of their characters funny or even interesting. For example, if a fanfic portrays Zeus in a more comical way than in the original, it could make him chuckle.
Poseidon could be quite entertained by the fanfiction about his son Percy. He might appreciate the creativity of the fans. Zeus, as a rather strict and proud god, may be offended if the fanfiction doesn't uphold his dignity. Hades, who is often seen as a bit of an outcast among the gods, might be more open - minded. He could be interested in how mortals imagine his domain and his role in the story. He might also find some of the unique interpretations of his character refreshing, unlike Zeus who is more likely to be affronted by any deviation from the 'proper' view of him.
Well, he might be amused. He could find the different interpretations of his character and the events in the original story quite interesting. Maybe he'd chuckle at some of the more out - there ideas the fanfiction writers come up with regarding his relationships with other gods or his role in Percy's adventures.
Some of them might be offended. If the fanfiction portrays them in a way that goes against their self - perceived grandeur or if it misrepresents their myths and legends. For example, if a fanfiction makes Zeus look like a bumbling fool instead of the powerful king of the gods, he might not be too happy about it. However, others might see it as a form of flattery that mortals are so interested in their tales that they create their own versions.
They might read it to gain new perspectives on magic. The Lightning Thief has its own unique magic elements, and the fanfiction can offer different takes on how magic works in that world. This could be inspiring for wizards who are always looking to expand their knowledge of magic.
Perhaps he's just curious. He wants to see how other fans are interpreting the world he's a part of. It could be a way for him to feel more connected to the fan community.
