A possible plot is that there is a magical event that switches the minds of Stoick and Baby Hiccup. So Stoick has to figure out how to take care of himself as a baby while Hiccup, in Stoick's body, has to deal with the responsibilities of being the chief. It would be full of comical and heartwarming moments as they both learn about each other in a very different way.
The relationship could be developed by having Stoick tell Baby Hiccup stories about their family's past. This would create a bond as Hiccup grows up with a sense of his heritage. For example, Stoick could tell tales of great battles fought by their ancestors, and Hiccup would listen in awe.
Unique? Well, it might be the way it can explore their relationship in a more...intense way. But since 'lemon' often involves mature themes, it can be a bit controversial. It might show a side of their bond that is different from the regular family - friendly portrayals in the original work.
One common theme is the growth of Hiccup under Stoick's guidance. Even if they have differences, Stoick's wisdom and experience help Hiccup become a better leader. Another theme is sacrifice. Stoick might sacrifice for Hiccup, or Hiccup for the ideals Stoick instilled in him.
One idea could be exploring how they prepare for the new arrival. They might start renovating their living space, like adding a new room for the baby. Stoick could be shown as overprotective, not wanting Valka to take any risks. Another could be that they share their hopes and dreams for the child. Valka might hope the baby inherits her love for dragons, while Stoick hopes for a strong future leader.
In this fanfiction, perhaps Stoick would be amazed by how much Hiccup has grown and changed in the future. He might see all the new inventions and ways of life that Hiccup has brought to Berk. Maybe there would be a moment of pride as he realizes his son has become a great leader.
I'm not entirely sure about specific Stoick and Hiccup lemon fanfictions. But in general, when looking for such fanfictions, you can try searching on some well - known fanfiction platforms. Just be cautious as the content can be quite adult - oriented in nature. It's also possible that there are more family - friendly interpretations that focus on their strong bond without the more inappropriate elements.
Well, writing a Stoick and Hiccup lemon fanfiction is a bit tricky. You should start with researching the 'How to Train Your Dragon' universe thoroughly. For the lemon part, you need to be very careful about how you handle the mature themes. You could start with a scenario where there's some sort of conflict or deep emotional moment between them that leads to the more adult - like interactions. However, be aware that this type of fanfiction might not be welcomed by all fans of the original work, as it can be seen as going against the family - friendly nature of the franchise.
The main characters are clearly Stoick and Hiccup. Stoick is Hiccup's father, and in this fanfiction, their encounter forms the central plot. Hiccup, as the character from the future, has likely developed and changed a great deal since Stoick last saw him.
One idea could be Hiccup discovers a hidden tribe in a remote jungle. Another could be that he encounters a mythical creature in an uncharted ocean region. Maybe he also teams up with a group of international dragon riders to save a world - spanning dragon sanctuary.
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.
