Harry would be extremely angry and immediately rush to her rescue. He has a strong sense of loyalty towards Hermione and would not tolerate her being in such a dangerous situation. Ron, on the other hand, would also be very worried. He might start panicking a bit at first but then quickly gather his courage and follow Harry's lead in trying to free Hermione.
Hiccup's friends would be extremely worried. Astrid, being Hiccup's closest friend and love interest, would probably be the first to take action. She would gather the other riders and start planning a rescue mission right away. Snotlout might initially be a bit hesitant, but the thought of losing Hiccup would push him to join in. Fishlegs would use his knowledge of dragons to figure out where Drago might be hiding Hiccup.
Hiccup might be very resistant at first. He's always been an independent thinker, so being forced into a marriage would go against his nature. He could try to find ways to escape the situation, like running away or finding loopholes in the marriage contract. But as he spends more time with Astrid, he might start to see her in a different light and become more accepting of the situation.
A really popular one is 'Lily's Boy'. It offers a different perspective on Harry's journey, exploring how things could have been different if certain events had other outcomes. It's well - written with great character development.
Well, it could be about a more aggressive or unforgiving version of Harry Potter in fan - created stories. Maybe it shows Harry in situations where he has to be really tough and make hard decisions, different from the more benevolent Harry in the original books.
He would probably be shocked at first. Just imagine seeing an older version of yourself. He might be a bit skeptical too, thinking it could be some kind of trick.
Stories about the different magical creatures in the HP world are also very interesting. Take the Hippogriff as an example. Buckbeak's story is full of magic and wonder. Hagrid's teaching about how to approach this proud creature shows the unique charm of the magical world.
