Think about Astrid's characteristics. If she's known for her loyalty, a nickname like 'Astrid, Hiccup's Loyal Blade' could work. It combines her loyalty to Hiccup and her warrior - like nature.
You can draw inspiration from the story's setting. Since they live on Berk which has a Viking culture, a nickname like 'Astrid, the Valkyrie of Berk' would be fitting. Valkyries are strong female figures in Norse mythology, just like Astrid in the How to Train Your Dragon universe. Another option is to look at her relationship with Hiccup and the dragons. For instance, 'Astrid, the Dragon - tamer's Muse' as she is an important part of Hiccup's life as a dragon - tamer.
One idea could be 'Astrid the Braveheart' as it shows her fearless nature. Another could be 'Astrid, the Dragon - friend' since she has a connection with dragons through Hiccup. Also, 'Astrid, the Shieldmaiden' would be great as it emphasizes her warrior side.
You can focus on their adventures together. For example, describe how they team up to fight a new dragon threat in Berk. This way, you can show their teamwork and the growth of their relationship in a non - sexual way.
In fanfics, Astrid could be mad at Hiccup for various reasons. One reason could be that he breaks a promise to her. For instance, if he promised to help her train a difficult dragon but then backs out because he got distracted by another project. This would make Astrid, who values loyalty and commitment, mad at him. Another reason might be miscommunication. If Hiccup doesn't clearly express his intentions or feelings, it can lead to misunderstandings and Astrid's anger.
She might be obsessed because she's a big fan of the original story and the fanfics allow her to explore more of Hiccup's story.
Well, on the island in the fanfic, they might have had an adventure involving solving a mystery or encountering a friendly tribe.
No, writing such sexually explicit fanfic is not appropriate as it involves inappropriate and vulgar content that goes against moral and ethical standards.
I'm not sure if there is such a fanfic specifically. Fanfiction can cover a wide range of scenarios, but this particular one might be a bit controversial in the context of the 'How to Train Your Dragon' fandom. It could exist in some corners of the fanfiction world, but it's not a common or widely known plot that I'm aware of.
There are many great Astrid and Hiccup fanfics out there. You can start by looking on fanfiction platforms like Archive of Our Own. Search for stories that focus on their adventures together, their relationship growth, or how they face challenges in the How to Train Your Dragon universe. Some fanfics might explore their teamwork in training dragons or their personal development as leaders in Berk.
Maybe she doesn't like the way some fanfics portray her relationship with Hiccup. Fanfics can sometimes deviate a lot from the original story, and she might be against those inaccurate or out - of - character interpretations.
I'm not sure if there is an official such fanfic. Fanfics can cover a wide range of themes and scenarios, but this one might be a bit controversial or not in line with the original story's tone in some views. However, the fanfic community is so vast that there could potentially be something like it out there.
