Hiccup might be interested. As an open - minded character, he would likely be curious about how fans see his world and adventures. He might pick up on new ideas from the fanfiction and even consider them for his own future endeavors.
Astrid, on the other hand, could be a bit more critical. She is a practical character, so she might question some of the more far - fetched elements in the fanfiction. But she could also find some of the character - driven stories quite engaging if they stay true to the spirit of the original characters.
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.
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.
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.
Happy Hogan might be entertained. He has always been a supporter of Tony Stark, and seeing the various fan - made stories about Iron Man would be like getting extra stories about his boss and friend. He might even share some of the more hilarious fanfiction with his co - workers.
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.
Fanfictions about watching HTTYD 3 in the past often focus more on the viewer's personal experience and how the movie affected them. Normal HTTYD 3 fanfictions usually center around the events and characters within the movie's universe directly.
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.
They might feel a bit embarrassed. After all, fanfiction often contains some over - the - top or cheesy scenarios that the characters may not be used to seeing themselves in.
Some might be flattered. It shows that fans are interested enough in them to create their own stories.
They might get angry if the fanfiction shows the heroes in a very positive light and the villains as weak or stupid. They have their pride and don't like to be made fun of or belittled, even in fan - made stories.
