They might be quite amused. For example, Will Graham might be intrigued by how others perceive his complex relationship with Hannibal. He could find some fanfictions that really dig deep into his psychological turmoil in a way that surprises him.
Hannibal Lecter himself would probably have a very haughty and perhaps slightly bemused reaction. He might see some of the fanfiction as rather simplistic in their understanding of his character. But at the same time, he might be secretly flattered that people are so interested in his persona.
Some characters like Jack Crawford might be dismissive. He is a no - nonsense FBI agent and might think fanfiction is just a waste of time and not in line with the real investigation and profiling work he does. So he would probably just roll his eyes and move on.
Typically, it is legal. Fanfiction exists in a bit of a grey area legally, but for the most part, as long as it's non - commercial and not causing harm to the original brand or creators. The creators of Hannibal might not actively promote fanfiction, but they also don't usually go out of their way to stop it. So, if you're just enjoying the fan - created stories, you should be in the clear.
If the characters watch Hannibal fanfiction, it could lead to some interesting self - reflections. They might see how fans perceive their relationships, like Hannibal and Will's complex bond. They could either embrace the fan - created ideas or reject them vehemently depending on their personalities. For example, Hannibal might find some of the more violent or grotesque interpretations in the fanfiction to his liking as it aligns with his dark nature, while Will might be more conflicted as he has a more moral core.
At first, Will would be in shock. But as time passes, he would start to analyze Hannibal's motives. He is a profiler, after all. He might try to use his psychological knowledge to manipulate Hannibal in return. He could also go through periods of anger, resenting Hannibal for taking away his freedom. And there might be moments of confusion as he tries to figure out if there is any part of Hannibal's actions that could be considered 'caring' in his warped way.
One good source could be Archive of Our Own (AO3). It has a vast collection of fanfiction for various shows, including Hannibal. There are different genres and ratings to choose from. Another option might be FanFiction.net, though the interface might not be as modern as AO3 but still has a lot of content.
They might be quite surprised. Some characters could find it strange to see their own stories being reimagined in different ways by fans. For example, if Sherlock Holmes were to watch elementary fanfiction, he might be intrigued by the new interpretations of his deductive reasoning skills or his relationships with other characters like Watson.
The characters might also feel a sense of flattery. If they see that the fanfiction writers are so passionate about their world and go to great lengths to create these stories. Kristoff, for instance, might be happy that fans are interested enough in his character to include him in different adventures in the fanfiction, even if those adventures are a bit far - fetched from his real - life (in - the - movie - life) experiences.
Well, some characters might be a bit critical. If the fanfiction strays too far from the essence of their personalities or the story of Encanto, they could be disappointed. Take Abuela, for instance. If a fanfiction shows her in a completely uncharacteristic way, she might not like it. Also, characters like Bruno might be amused to see how the fans imagine his hidden years and his relationship with the family in the fanfiction.
They might be surprised at how their actions are reimagined. For example, Iron Man could be astounded to see a version of himself in a situation he never thought of in the official storylines.
The characters might find it interesting to see different scenarios that the fans create for them. Maybe there are fanfictions that put them in completely different worlds or situations, like facing a new kind of dragon that doesn't exist in their own world. This could make them think about how they would actually react in such strange circumstances.
