One interesting fanfiction could be where Thranduil uses his elven magic to counter dragon fire. Maybe he creates a shield of ancient elven power that not only withstands the intense heat but also reflects the fire back at the dragon. This would show his great power and wisdom as an elven king.
In some fanfictions, Thranduil might have an encounter with a dragon whose fire has a special property. For example, the dragon fire could be enchanted to turn anything it touches into ice. Thranduil has to find a way to break the enchantment and defeat the dragon. He could seek the help of a powerful wizard or use his own knowledge of the forest's magic to do so.
Well, there's a fanfiction called 'Thranduil and the Lost Artifact'. In this story, Thranduil embarks on a quest to retrieve a powerful and ancient artifact that has been lost for centuries. It's full of action and mystery. Then there's 'Thranduil's Alliance', which focuses on his forging of an unexpected alliance with another race to protect his kingdom. Also, 'Thranduil's Secret Heir' is quite engaging as it reveals a hidden part of his family history.
Another place to look is Archive of Our Own (AO3). There are a lot of talented writers in the Tolkien fandom there. A good fanfiction might involve Thranduil having to protect his people from a dragon's fire. Maybe the dragon has been awakened by some dark magic and Thranduil is the only one who can stop it. The fanfiction could explore his character development as he overcomes this great threat.
One great 'Fire Emblem Dragon Robin' fanfiction is 'The Dragon's Bond'. It delves deep into the relationship between Robin and the dragon characters. The story has a lot of character development and exciting plot twists.
It could be that there was some sort of magic involved. Maybe an enemy of Thranduil cast a spell that made the dragon more aggressive towards him. The dragon fire might have some special properties due to this magic, and Thranduil's burns could be not just physical but also have some sort of curse or negative effect on his being. He then has to find a way to break the curse while dealing with his injuries.
Yes, there are quite a few. You can find them on various fanfiction platforms like Archive of Our Own. Some explore their relationship in different ways, such as Tauriel being a key figure in helping Thranduil overcome his past traumas and find love again.
He might become more cautious. After experiencing the pain of the dragon fire, he could be more hesitant in engaging in battles, especially those involving dragons. This could change his military strategies.
One great 'Zuko dragon fire' fanfiction is 'The Dragon's Fire Within Zuko'. It delves deep into Zuko's connection with the dragon fire, exploring how it changes him not just physically but also in his journey of self - discovery. Another is 'Zuko and the Flames of the Dragon', which has some amazing action scenes where Zuko uses the dragon fire in battles.
One common theme could be family conflict. Given their relationship as father and son in the lore, there might be stories where their differences cause emotional pain. For example, Thranduil's strict ways might clash with Legolas' more adventurous spirit, leading to hurt feelings.
One common theme is power dynamics. Since Thranduil is a powerful elf king and dragons are also very powerful creatures, their interactions often involve a struggle for power or respect. Another theme is mystery. Dragons are often mysterious in these stories, and Thranduil tries to figure them out.
Fanfiction.net is another good place. There are a lot of fan - created stories there. Just type in 'Zuko dragon fire' and browse through the results. However, the interface might be a bit more dated compared to AO3. Some Tumblr blogs also post fanfictions or link to them. You can search for relevant tags like #Zuko #DragonFire #Fanfiction.
