Well, he might be really intrigued. Harry is used to magic in his own world, but the magic and the world of HTTYD in the fanfiction could be a whole new and exciting experience for him. He might start comparing the different types of magic, like how the wizards in his world use wands and spells, while in HTTYD there are dragons with their own special abilities.
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.
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.
His view of magic might expand. In his world, magic is mainly about spells and potions. But after reading HTTYD fanfiction, he would see that magic can also be about the bond between humans and creatures like dragons. This could make him think more about the potential of magic in his own world beyond just what he has been taught at Hogwarts.
Good 'Berk Watches HTTYD 2' fanfiction often stays true to the characters. The personalities of the Berk inhabitants should be recognizable. Also, it should have a clear plot that either expands on the events in the movie or offers a new and interesting take. For example, if it's about how Berk prepares for the dragon battles, it should be detailed and logical.
There's a fanfiction called 'Into the Unknown with Dragons' that has gained a lot of popularity. It takes the characters from httyd and rtte on a journey to unexplored lands filled with new types of dragons. The story is full of adventure and mystery, which is what attracts a lot of readers. Additionally, 'The Dragon Riders' Redemption' is popular as it delves into the past mistakes of the dragon riders and how they strive to make amends during their further adventures in the rtte - like setting. It has a great mix of action, emotion, and character development.
There probably are. 'How to Train Your Dragon' has a huge and passionate fan base. Fanfiction writers often take the characters, such as Hiccup (from what I think you meant) and other related characters, and create their own stories. So it's very possible that there are works of fanfiction that someone could watch, perhaps in the form of written stories being read aloud or turned into some kind of visual adaptation by fans.
He might also be a bit confused at times. Some fanfictions deviate a lot from the real events in his life. For example, if there's a fanfiction where he has a completely different upbringing, it would be strange for him to read about. He could also feel a sense of flattery that so many people are interested in his story and want to create their own versions of it.
One popular 'Berk Watches HTTYD 2' fanfiction might be 'A New Perspective on Berk'. It offers a unique take on how the people of Berk view the events in HTTYD 2. Another could be 'Berk's Reactions', which focuses on the various reactions of the Berkian characters during different parts of the movie. There's also 'Berk's Insights', which delves deeper into how Berk's culture and values are influenced by what happens in HTTYD 2.
She might gain new perspectives on the characters and story. Since she's a part of the How to Train Your Dragon universe, seeing different interpretations in fanfiction could be interesting.
