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, 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.
One way could be to start with Harry finding a book about Smaug in the Hogwarts library. He becomes so intrigued that he starts to have dreams about the dragon. Then, as the story progresses, he might use his magic to create a portal to the world where Smaug exists and tries to communicate with 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.
One great fanfiction could be where a character becomes an Animagus modeled after Smaug from 'The Hobbit'. In this story, perhaps they use their new form to protect Hogwarts in a way similar to how Smaug guards his treasure. They could fly over the school, their scales glinting in the sun, and scare off any dark wizards approaching. Another possibility is a story where a Smaug - like Animagus has to deal with the politics of the wizarding world, being both feared and respected like Smaug was in his own story.
It could be a very exciting story. Harry might inherit some dragon - like qualities such as being able to breathe fire in a different, magical way. He could also have a natural affinity for treasure, which would be a fun twist on his character. And his connection to Smaug could bring in elements of Middle - earth's dragon lore into the Harry Potter universe.
First, do your research on both Harry Potter lore and Smaug's characteristics. For example, understand how Animagi work in the wizarding world, like the process of transformation and the rules around it. Then, think about how Smaug's traits, such as his greed for treasure, his fire - breathing ability, and his great size, can be incorporated into a Harry Potter character as an Animagus. You could start with a simple plot idea, like a character who discovers they are an Animagus with Smaug - like features and has to keep it a secret while using it to their advantage in the wizarding world.
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.
