Their relationship might become more equal in some ways. As dragons, they are both facing a new and strange existence, so they have to rely on each other more. They might develop a new understanding of each other's strengths and weaknesses.
One interesting plotline could be that as they turn into dragons, they have to quickly learn how to fly and hunt like real dragons. They might face challenges from other dragons who see them as outsiders in their new dragon forms.
One great fanfiction is 'A New Adventure for Hiccup and Astrid'. It shows them exploring a new, uncharted island filled with strange dragons. The story really captures their adventurous spirits as they face challenges together and grow closer in the process.
The world of DreamWorks Dragons is so rich and full of possibilities. In fanfiction, writers can take Hiccup and Astrid on new adventures that we might not see in the original series. For example, they can be in different time periods or face new kinds of dragons. It gives fans the chance to be creative and expand on the story they love. Also, their relationship has so many layers, from friendship to love, and fanfiction can explore all of those aspects in great detail.
In the fanfiction, perhaps there's a moment when Hiccup gets injured while protecting the village. Astrid stays by his side day and night, taking care of him. She reads to him, makes him his favorite food, and in those quiet days, they realize how much they mean to each other. Their love deepens as they share these tender moments.
It develops gradually. At first, they might be just friends who respect each other's skills. But as they go on more adventures together, they start to notice little things about each other. For example, Hiccup notices how Astrid is always the first to volunteer for dangerous tasks because of her bravery. And Astrid sees how Hiccup's intelligence always gets them out of tough situations.
First, get familiar with the characters' personalities and the world of How to Train Your Dragon. Then, come up with a plot that combines their relationships and the magic of the dragons. Add some twists and turns to keep readers engaged.
One possible fanfiction could be about how Hiccup and Astrid deal with the pregnancy. Hiccup might be overprotective, constantly worried about Astrid and the baby. Meanwhile, Astrid could be trying to keep up with her normal Viking duties while also preparing for motherhood. And the lemon element could be a symbol in the story, perhaps it's something Astrid craves during her pregnancy, leading to some humorous or heartwarming scenes between her and Hiccup as he tries to find the perfect lemon for her.
Astrid might initially be in shock. She could just stand there, frozen, unable to believe that Hiccup is really gone. Her eyes wide open and her body trembling as she tries to process what has just happened.
