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.
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.
Astrid could also be a main character. Maybe she runs away for some reason and her dragon Stormfly is with her. Or she could be chasing after Hiccup and Toothless if they are the ones on the run. There are also other Vikings or dragons that could be main characters depending on the specific plot of the fanfic.
In addition to Hiccup and Toothless, Astrid is also an important character. She is a strong - willed Viking girl and Hiccup's friend. There are also other dragon riders like Fishlegs, Snotlout, and the Twins who often appear in the graphic novels. They each have their own dragons and personalities. These characters together create a rich and diverse cast that drives the stories forward, whether they are on adventures, facing challenges in the Viking village, or exploring new lands with their dragons.
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.
Yes, there are likely some popular ones. For instance, some fanfictions that explore the relationship between Hiccup and Astrid during the time leading up to HTTYD 2 are quite popular. They might show how their relationship evolves and how they support each other in anticipation of the new threats in the second movie.
Some characters might be amused. For example, Hiccup could find it interesting to see different interpretations of his adventures in HTTYD 2. He might laugh at the creative liberties taken in the fanfiction.
The characters in 'httyd' would likely have complex reactions to the future in the fanfiction. Hiccup, for example, has always been a forward - thinking character. He would likely be intrigued by the possibilities the future holds, whether it's in terms of dragon - human relations or new inventions. However, he would also be concerned about protecting his tribe and the dragons. Astrid would be more practical. She would assess the potential threats and benefits. The dragons themselves, such as Toothless, would react based on their bond with their human counterparts. If they sense that Hiccup is positive about the future, they might be more open to it, but if there are signs of danger, they would be on high alert.
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.
