One common theme is gender role reversal. Since Arthur is typically male in the original legends, fanfictions with a female Arthur often explore how she navigates a world that has certain expectations for men. For example, she might face different challenges when it comes to leading knights or being accepted as a ruler.
Saber from Fate/Stay Night would be an obvious choice. Since she is also related to the Arthurian legend, there could be a lot of interesting interactions between them. They could compare their experiences as king, or even fight side by side against a common enemy.
One great Arthur Pendragon hurt fanfiction is 'The Wounded King' which delves into his emotional turmoil after a major battle. It shows his struggle to regain his strength both physically and mentally.
Well, in such a fanfiction, they could team up against a common enemy. Maybe an ancient dark force that has been awakened in both their times. Their combined knowledge of magic from different eras would be a great asset.
A fanfiction that stands out is 'Arthur and Merlin: A Different Path'. This one takes a different turn from the original storyline. It imagines a world where Arthur discovers Merlin's magic much earlier. This changes the whole dynamic between them, and they face different challenges together. There is also 'The Adventures of Merlin and Arthur in the Enchanted Forest'. It's full of exciting quests and the development of their friendship.
There's also 'Female Arthur Pendragon: A New Reign' which is quite popular. In this fanfiction, the female Arthur has to deal with the politics of Camelot in a more nuanced way as a woman. It delves deep into the relationships she forms, both romantic and platonic, and how they are affected by her gender. The writing style is engaging and it keeps you hooked from start to finish.
One possible reason could be a misunderstanding. Maybe Merlin did something that Arthur misinterpreted as betrayal or dishonesty. For example, if Merlin was secretly helping an enemy for a greater good that Arthur wasn't aware of at the time.
Another possibility is a story where a vampire in The Vampire Diaries discovers an ancient relic related to Arthur Pendragon. This leads to a journey through time where they end up in Camelot. There, they face the challenges of Arthur's court, and perhaps a vampire falls in love with one of Arthur's knights or a lady in waiting. It would be a story full of adventure, romance, and the clash of two very different worlds.
One possibility in Hermione and Arthur Pendragon fanfiction could be a story where Hermione uses her modern magical knowledge to help Arthur Pendragon in his time. For example, she could introduce new spells or ways of using magic that were not known in his era. This could lead to a series of adventures as they face challenges together, like defending Camelot from a new dark magic threat.
One great fanfiction is 'The Once and Future King's Heart'. It beautifully delves into the deep bond between Merlin and Arthur. It shows how their relationship evolves over time, with Merlin's magic playing an important role in protecting Arthur while also creating some interesting conflicts.
