Yes, it's possible that Maximum Ride could read fanfiction. Just like many fans of a series, the character within the story, if in a more meta - situation, might be interested in reading the creative interpretations that fans have written about their own adventures.
Fang would probably be protective. He has always been close to Maximum Ride, and with her pregnant, he would be on high alert to keep her safe from any threats. Iggy might be a bit more practical, helping to set up a safe place for her to stay during the pregnancy. Nudge would be excited and full of questions, constantly asking about the baby.
The character development in fanfiction can be more focused on emotional growth. Take Nudge for example. In fanfiction, she could be explored more in terms of her insecurities and how she overcomes them, which might not have been the main focus in the original books. Fanfiction allows for a deeper dive into the emotional states of the characters.
Well, if Maximum Ride read fanfiction, it could have several outcomes. Firstly, they might be really flattered that fans are so interested in their story that they create their own versions. On the other hand, they could also be a bit taken aback if the fanfiction goes in a very different direction from what they expect or if it misrepresents their character in some way. However, it could also inspire them to think about their own story in a new light and maybe even incorporate some of the more interesting ideas from the fanfiction into their own understanding of their world.
One great 'Maximum Ride and Percy Jackson Fanfiction' is 'The Crossover Quest'. It combines the unique powers and personalities from both series really well. The story has an engaging plot where the characters from Maximum Ride and Percy Jackson have to team up to face a common enemy. It's full of action and adventure, which makes it a really exciting read.
I don't have the exact number off the top of my head. But a quick search on manga forums or asking fellow manga enthusiasts might help you get the answer you're looking for.
