Percy would feel a mix of curiosity and amusement. He'd be curious about how others see his adventures and amused by the creative liberties taken. Annabeth might be a bit frustrated at times. She's so used to the facts and proper interpretations, so any inaccuracies in the fanfiction could irk her. Grover would simply feel flattered that people are interested enough in their story to write fanfiction.
If PJO characters read the fanfiction books, it could be quite an experience. Percy might find it strange to see different versions of himself. For example, some fanfictions might show him with powers he doesn't actually have. Annabeth would likely analyze how the fanfiction authors handle the strategic elements of their quests. She might be impressed by some creative solutions in the fanfictions or disappointed by unrealistic ones. Grover, on the other hand, would be excited to see how the fan community portrays his relationship with Percy and the others.
It can be considered common. There are a large number of PJO fans out there, and fanfiction is a popular medium in fan communities. Since the official books have a set storyline, fanfiction offers a chance to expand on it, so many 'mortals' (fans) are attracted to it.
They might be quite surprised. Some characters could be amused to see different interpretations of their adventures. For example, Percy might find it interesting how fans imagine his internal thoughts during the events in 'The Son of Neptune'.
One benefit is that it allows you to explore different interpretations of the original PJO world. Fanfiction often takes the existing characters and settings and twists them in new and interesting ways. It can also give you a deeper connection to the fan community as you share in the creativity of fellow fans.
A really cool 'PJO Read the Books' fanfiction is 'Beyond Camp Half - Blood'. It takes the characters out of the familiar camp setting and into a whole new world filled with new challenges and adventures. The author does a great job of maintaining the essence of the original characters while also making them grow and develop in new and unexpected ways.
For demigods, it could either reinforce their existing views or introduce new perspectives. If a fanfiction delves deeper into a certain aspect of their world like the powers of a god, they might gain a new understanding. Mortals would have a more comprehensive view of the PJO world. They would learn about different characters and their backstories that might not be fully explored in the original books.
One great 'pjo avengers crossover fanfiction' is 'The Demigod Avengers'. It has an exciting plot where the demigods from Percy Jackson and the Olympians join forces with the Avengers. The character interactions are really well - written, like when Percy uses his water powers in a fight alongside Thor's lightning.
For the friendship between Percy and Grover, Grover might start treating Percy a bit differently if the fanfiction portrays Percy in a new way. Maybe if the fanfiction makes Percy out to be a great leader in a more pronounced way, Grover could become more deferential to Percy, which Percy might find a bit strange at first.
One great fanfiction could be 'The Lost Hero's New Quest'. It takes the characters from the HOO series and puts them in a new, exciting adventure where they have to face a long - forgotten ancient evil. The author does a great job of staying true to the original characters' personalities.
