The plot could involve Hiccup joining the marines to seek new adventures and knowledge. Once there, he discovers that the marines have their own set of problems, such as dealing with internal politics and external threats. Hiccup, with his kind heart and determination, tries to make a difference. He might introduce some of the Berkian technology or ideas to the marines, like new ways of building defenses or navigation techniques.
Astrid could be one of the main characters. She might follow Hiccup to the marines to keep an eye on him or to have her own new adventures. Another character could be a tough marine sergeant who initially doubts Hiccup but later comes to respect him. There could also be a marine scientist who is interested in Hiccup's knowledge of dragons.
In my version of the fanfiction, the female Hiccup could be a prophesied savior. There could be an ancient prophecy that a female with the spirit of Hiccup will come and unite all the dragon tribes. She starts off not believing in the prophecy but as she goes through various challenges and meets different dragon species, she gradually realizes her true destiny. Along the way, she has to overcome the doubts of her own people and the opposition from some of the more traditional dragon tribes.
In this fanfiction, after getting out of rehab, Hiccup might face some skepticism from the people of Berk. But he's a changed man. He starts by sharing his experiences in rehab, how he overcame his inner demons. This new - found openness could inspire the other Vikings, especially the younger ones who look up to him. He then gets back into dragon - riding, but with a more cautious and responsible approach, showing that he's truly grown.
If Harry Potter were to join the Marines, it would be a very interesting combination. He might struggle with the muggle technology at first, but his determination and courage would help him adapt quickly. His magical abilities could potentially give the Marines an edge in combat situations, like using magic to disarm enemies or create barriers. Also, his experience with teamwork from his time with Ron and Hermione could enhance the camaraderie within the Marine unit.
Well, Percy Jackson joining the Marines could be really interesting. He has his demigod powers which could make him an extraordinary marine. His ability to control water could be used in various combat situations, like creating diversions or even rescuing comrades in water - based operations. Also, his combat skills learned from Camp Half - Blood would give him an edge in hand - to - hand combat.
One possible reason could be that he's under a great deal of stress. Maybe there are new threats to Berk that he's trying to deal with alone and it's getting to him. Another reason might be personal issues, like if he's having problems with his relationship with Astrid or his father. Or perhaps he's frustrated with the dragons not following his commands as he expects, which makes him lash out at everyone around him.
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.
One interesting plot idea could be Hiccup and Astrid going on a secret adventure to a new, uncharted island. They face new dragons and have to work together to survive. Another could be a story where they have to deal with a rift in their relationship due to a misunderstanding, like Astrid thinking Hiccup is spending too much time with a new dragon rider. A third idea is a time - travel plot where they go back in time and have to change something in Berk's history to save the future.
Yes, he might. Hiccup is a character from 'How to Train Your Dragon' series. If there is an interesting HTTYD 2 fanfiction out there, it's possible that someone could imagine Hiccup reading or being involved in it in some way in the context of fan - created stories.
A plot point could be a misunderstanding. Maybe Astrid sees Hiccup spending a lot of time with a new female dragon rider and gets jealous. This causes a rift between them, but then they have to work together to save Berk from a new threat. During this, they clear up the misunderstanding and their love becomes stronger.
