Smaug

Smaug is introduced relatively late in the story. You'll come across him in a significant part of the plot.

Smaug was killed when Bard the Bowman shot an arrow into a weak spot on his underbelly.

Yes, there might be some. Fanfiction platforms often have a wide variety of crossovers. You can check websites like Archive of Our Own (AO3). Writers love to combine different fictional universes, and Harry Potter and Smaug from 'The Hobbit' are interesting characters to put together in a story.

Well, it depends on how you define 'good'. There could be fanfictions exploring the concept of a pregnant Smaug in different ways. Maybe some are more comical, imagining how the other characters in the Middle - earth universe would react to such a situation. Others could be more serious, delving into the implications it might have on the lore or the world - building.

Well, in male pregnant Smaug fanfiction, one of the main characteristics would be the unique take on Smaug's biology. Since dragons in Tolkien's lore are quite different from humans, the idea of a male Smaug being pregnant challenges the traditional concepts. It might involve creative interpretations of dragon reproduction and how that would work in a male. There could also be elements of magic or some unforeseen circumstances that lead to this situation.

Well, the plot could involve Harry being on a quest and stumbling upon Smaug's lair. Since Harry has his knowledge of magic and Smaug has his dragon - like power and greed for treasure. Harry could be tempted by the treasure as well, but his moral compass as a wizard would make him try to either reason with Smaug or defeat him in a magical duel to protect the local people of Middle - earth. This would create a really interesting dynamic between the two characters.

Often, there are themes related to the protection of the unborn. Since Smaug is a powerful and feared creature, the idea of something precious (the unborn) within him could lead to themes of safeguarding. Also, there might be themes of change, as Smaug's state would surely bring about some sort of transformation in his behavior or the way others perceive him.

There probably is. Fanfiction writers love to experiment with different ideas. This idea of Harry Potter being Smaug's son could lead to some really interesting plotlines. For example, how would Harry's Hogwarts education be affected by his dragon heritage? Would he have special powers related to dragons? And how would the wizarding community react to his rather unusual parentage? There are so many possibilities for a story like this in fanfiction.

The presence of a central 'treasure' concept. In the Smaug stories, there's the literal treasure that Smaug hoards. In Harry Potter, you could consider things like the Philosopher's Stone or the secrets of Hogwarts as treasures. Fanfiction might explore this similarity by creating scenarios where the characters' pursuit of these 'treasures' is similar to the way characters in Smaug stories approach his hoard.

Well, perhaps in terms of the sense of wonder and magic. Smaug is a magnificent and powerful dragon in his own lore, and Harry Potter has a whole world of magic. Just as Smaug's hoard is filled with mystery and allure, Hogwarts and the magical artifacts in Harry Potter's world also have that kind of attraction. They both create a world that draws readers in with their unique magical elements.
