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.
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.
This is such a unique idea. Firstly, we need to consider that 'httyd' in this context is fictional, but if we imagine it could watch fanfiction. It might react in different ways depending on the type of fanfiction. For instance, if it's a well - written action - packed fanfiction that stays true to the spirit of the original, it might enjoy seeing its world expanded. However, if it's a fanfiction that goes against the core values of the httyd world, it might be a bit shocked or dismayed.
The fanfiction might focus on how the relationships between the characters change when the two worlds of HTTYD and HTTYD2 collide. For example, Astrid might have to adapt to new ways of dragon riding she sees in HTTYD2, and this could cause some friction or growth in her relationship with Hiccup. It could also involve the dragons from the first movie learning new skills from the HTTYD2 dragons.
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.
One interesting HTTYD2 fanfiction is 'The Next Adventure'. It continues the story after the events of HTTYD2, exploring new lands and challenges for Hiccup and Toothless. It really captures the spirit of the movies.
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.
Well, it depends. Fan writers have a lot of creativity. They could create alternate storylines where the egg has special powers or where Valka has to protect it from new threats.
