Well, in the real world, it's not possible. But if we were to think in a more creative, fictional sense, like in a meta - story where the httyd world intersects with our own digital or written realm in some magical way, then maybe. But generally, no, as it's just a fictional entity without the physical or mental faculties to do such a thing.
The other characters like Fishlegs would probably be really into it. He loves stories and knowledge, so seeing different takes on the HTTYD 2 story in fanfiction would be like a goldmine for him. He might start analyzing the details and comparing them to what he knows from the real events.
Some characters might be amused. For example, Hiccup, being the open - minded and curious one, could find it interesting to see how fans imagine different scenarios. He might even get some new ideas for his own adventures.
Another option could be Wattpad. While it has a wide variety of content, you might be able to find some great HTTYD2 fanfiction related to HTTYD there. It's important to note that the quality can vary, so you may need to sift through some stories to find the really good ones.
They could also be confused. If the fanfiction takes a really wild turn from the original story, characters might not understand the new concepts or relationships presented. For example, if a fanfiction pairs two characters who have no interaction in the original in a romantic way, it could be bewildering for them.
Well, some characters might be amused. They could find the creative interpretations in the fanfiction quite interesting and might even laugh at the funny or unexpected scenarios. For example, Toothless from HTTYD might be curious about how he is portrayed in the fanfictions.
Astrid would also be a likely main character. In both movies, she plays an important role in Hiccup's life and the dragon - human relationships. She could bring her own skills and perspectives when the two movie storylines meet. And of course, Stoick might be there too, as his presence and leadership were important in the first movie and his legacy could play a part in the fanfiction that combines the two.
Fishlegs would likely have a very animated reaction. If he comes across some fanfiction that has really strange dragon facts, he'd be so shocked. He might start rambling on about how wrong it is according to his extensive dragon knowledge. His eyes would be wide and he'd be waving his hands around.
Yes, it's possible that some Vikings enthusiasts might also be into 'How to Train Your Dragon' (HTTYD) fanfiction. Since both Vikings and HTTYD have elements of adventure, dragons, and Norse mythology, there could be an overlap in the fan bases. Some fans of Vikings might be curious about different interpretations and stories in the HTTYD fanfiction world.
Yes, he might. Hiccup is a character from 'How to Train Your Dragon' series. If there is an interesting HTTYD 2 fanfiction out there, it's possible that someone could imagine Hiccup reading or being involved in it in some way in the context of fan - created stories.
