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.
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.
I really like the fanfic 'A Different Kind of Friendship'. It starts with Hiccup and Snotlout being forced to work together on a project in Berk. As they spend more time together, they start to understand each other better. The writer does a good job of showing their growth as characters.
One great 'Female Hiccup' HTTYD fanfiction is 'A Different Perspective'. It offers a really interesting take on the story with a female Hiccup character. The author does a wonderful job of re - imagining the relationships and adventures in the HTTYD world.
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.
One common theme is friendship. Hiccup and Toothless's bond is a deep friendship that defies species boundaries. Another theme is adventure. They often go on exciting quests together in these fanfictions.
Since 'lemon' fanfics are inappropriate, we can talk about common themes in regular Hiccup and Astrid fanfics. One common theme is their partnership in dragon - training and leading Berk. Another is their evolving romantic relationship, from initial attraction to deep love.
You can find it on fanfiction.net. There are a large number of stories dedicated to Astrid and Hiccup there. Just use the search bar and type in their names to start exploring.
Some fanfictions focus on their early days of getting to know each other. For example, a story where Hiccup is trying to teach Astrid more about Toothless and she is initially hesitant but then becomes fascinated, leading to a cute and heart - warming relationship development.
One common theme is the exploration of their different personalities. Hiccup is the intelligent and often reserved one, while Ruffnut is more brash and impulsive. Fanfictions usually play with how these differences either clash or complement each other.
