Ruby would be excited. She loves stories full of action and adventure, and Percy Jackson fanfiction would be right up her alley. Weiss might be a bit more reserved, but could still find aspects of it to enjoy, like the complex characters. Blake would be interested in the themes of the story, such as loyalty and friendship. Yang would be enthusiastic, especially about the fight scenes and the strong characters in the fanfiction.
When RWBY reads Percy Jackson fanfiction, their reactions would be quite diverse. Ruby, with her love for exploration and heroics, would be completely immersed in the stories. She'd be eager to share her favorite parts with the others. Weiss, being the more refined one, would initially be cautious but soon find the charm in the unique blend of mythology and modern settings. Blake would focus on the deeper meanings, like how the demigods deal with their dual identities, which she can relate to her own life as a faunus. Yang would be the most vocal in her enjoyment, shouting out her approval during the intense action scenes and getting really into the power - ups and epic battles in the fanfiction.
Percy's reaction would be a mix of confusion and fascination. The world of Kratos is so foreign to him, with different rules and a much darker tone. However, he would also be drawn to the hero's journey that Kratos undertakes in the fanfiction, comparing it to his own journey as a demigod.
Bruce Banner, when he's not in Hulk mode, would be really interested in the scientific aspects that might be hidden in the Percy Jackson fanfiction. Even though it's a world of magic, he could look for ways that the magic could be related to some kind of scientific principle. He might also be interested in how the characters control their powers, whether it's Percy with his water powers or the Avengers with their various abilities, and look for similarities in self - control and management of power.
He might be intrigued. After all, it's about a world he's somewhat connected to.
Percy could be a bit skeptical at first. He's been through a lot in his own world, and fanfiction might seem a bit strange to him. But as he reads more, he could get really into it. He might find himself rooting for the characters in the Red Pyramid fanfiction, especially if they remind him of his friends or himself in some way. For example, if there's a character who is an underdog but has great potential, just like Percy felt in his early days.
Athena, being the goddess of wisdom, might analyze the fanfiction. She could look at how the mortal writers understand the Greek mythology and use it to create new stories. She might be impressed by the intelligence and creativity of some of the fanfictions, or she might be critical of inaccuracies.
He'd probably be shocked. Percy is used to living his own story, not reading someone else's take on it.
Some of them might be entertained. For example, Thor could see the similarities and differences between his world and Percy's world of gods and monsters and find it humorous. Others like Black Widow might analyze the characters' motives and strategies in the fanfic as she is used to understanding people's minds.
He'd probably be very intrigued. Percy has a penchant for adventure and new things, and this fanfiction would be something completely different from what he's used to.
Apollo would probably love it. Since he is the god of poetry and creativity, he'd be intrigued by the different interpretations of himself in fanfiction. He might even get some new inspiration for his own creative works from it.
She might be shocked at some of the wild ideas in the fanfiction. Maybe she'd laugh at some of the more outlandish plot twists.
