Katniss might be shocked and a bit angry at some of the out - of - character portrayals in the fanfiction. She's used to being in control of her own story, and seeing others twist it could be irritating.
Peeta, on the other hand, would probably be more understanding. He might find it interesting to see different perspectives on their world and their relationship. He could even appreciate some of the more creative interpretations. For example, if a fanfiction explored a different side of his artistic nature that wasn't fully shown in the original books. He might be flattered by some of the positive portrayals of him in the fanfiction.
Some characters might be amused. For example, Katniss could find it strange to see different interpretations of her own story. She might be a bit irritated at first if the fanfiction misrepresents her motives or actions, but then she could also see the creativity in it.
Katniss could start to question her own identity. If the fanfiction presented her in ways she didn't expect, she might wonder if there were parts of herself she hadn't fully explored. For instance, if a fanfic made her out to be more emotional than she thought she was.
Perhaps they would be critical. If the fanfiction doesn't stay true to their own experiences in the Hunger Games, they might have issues with it. For example, if it misrepresents their relationships or their motives during the games.
They might have various reactions. Some characters could be amused by the different interpretations of their world and themselves. Others might be offended if the fanfiction portrays them in a negative or untrue light.
Some characters might be amused. For example, Denki Kaminari could find the wild and creative ideas in fanfictions really funny. He might share the funniest parts with his friends like Kirishima.
The Capitol citizens would likely be entertained. They live in a world of excess and novelty, so reading fanfiction about the Hunger Games characters would be just another form of amusement for them. However, the tributes from the districts might have a more complex reaction. For those from the poorer districts, it could be a source of hope or a cruel reminder of their situation, depending on how the fanfiction is written. For example, if a fanfic shows a district winning in a way that seems impossible in reality, it could give them hope, but if it's a cruel or inaccurate portrayal, it could be disheartening.
It would be really interesting. The characters from 'The Hunger Games' live in a very different world from that of 'Harry Potter'. If they read the fanfiction, they might be confused by the magic elements at first. For example, Katniss might find it hard to understand how wands work and spells are cast. But they could also be intrigued by the Hogwarts houses and the concept of a magical school.
Often, Katniss and Peeta remain central characters. Their relationship, which has been through so much in the original books, might continue to evolve in the fanfiction.
Katniss might gain new perspectives on her relationships. In fanfiction, her relationships with Peeta and Gale could be explored in different ways. This could make her re - evaluate how she feels about them in her own world. For instance, if a fanfiction delved deeper into a romantic aspect between her and Peeta that she hadn't fully considered, it could change her perception of their bond.
Some characters might be amused. For example, Harry Potter himself could find it quite interesting to see different interpretations of his adventures. He might chuckle at some of the more out - there ideas in the fanfiction.
