Other characters may be confused. Fanfictions often introduce concepts and situations that are not part of the original story. So, when characters read these, they might struggle to understand the new elements, like new magic systems or relationships that don't align with what they know from The Lord of the Rings.
There could be characters who are outraged. If the fanfiction goes against the established lore or their own values in the original work, they might be offended. For example, if a fanfiction portrays a noble character as a villain without proper justification, those characters might feel their reputations are being sullied.
Some frozen characters could be amused. Imagine Elsa from Frozen reading a fanfiction where she has a new adventure in a different kingdom. The creative ideas in the fanfiction might make her laugh or at least find it interesting.
Some characters could be confused. If the fanfic changes certain aspects of the original story significantly, for example, if it alters the relationships between characters in a way that's different from what they know, they would be at a loss. They may not understand why the writer made such changes. Also, if the fanfic contains some out - of - character moments for them, they might be quite puzzled.
In fanfiction, many Lord of the Rings characters can be shown reading books. For example, Gandalf, being a very learned character, could be reading ancient tomes in a fan - written story. This adds more depth to the character's intellectual side and can also be used to introduce new plot elements or pieces of lore. If he reads a mysterious book, it might lead him on a new quest or discovery within the fanfiction's narrative.
They may also be confused. Fanfictions often take the original story in new directions, and characters might not understand why certain things are written the way they are. For example, if a fanfiction changes the relationship dynamics between characters, they could be left scratching their heads.
They might be amused. Some characters could find the creative interpretations in the fanfiction quite interesting and it might make them laugh or at least bring a smile to their faces.
Some characters might be amused. For example, Frodo could find it interesting to see different interpretations of his journey. He might chuckle at some of the more outlandish ideas in the fanfiction.
In fanfiction, characters could read books about different races. Samwise might read a book about the dwarves, their culture, and their great works underground. This helps him understand Gimli better and also allows the author to explore the relationship between hobbits and dwarves more deeply. Also, characters like Galadriel could be reading books about the Istari (wizards), as it is in her nature to be curious about powerful beings in Middle - earth.
Others might be critical. For example, if the fanfiction goes against the established canon of the Danny Phantom universe, they could be annoyed or feel that it misrepresents them. They might think that the author didn't do enough research on their personalities or the story's lore.
They might be shocked. Since fanfiction can often deviate from the original plot, characters could be taken aback by unexpected storylines or characterizations.
They may also be indifferent. There could be so much fanfiction out there that they just get used to it and don't really care what's written about them in those fictional works. It could be like just another part of the whole South Park phenomenon that they are part of.
