One popular 'Fem Harry as Carlisle's Mate' fanfiction might be 'A New Destiny'. It explores how Harry, as a female in this AU, meets Carlisle and their relationship develops. It's interesting because it combines the magical world of Harry Potter with the vampire lore of Twilight.
There are several fanfictions on this topic. You can check out websites like Archive of Our Own. Look for tags like 'Fem Harry' and 'Carlisle's Mate'. Some fanfictions focus on the initial encounter between them, while others delve deeper into how they overcome the differences between their two worlds - the wizarding world and the vampire world.
In these fanfictions, the contrast between Fem Harry and Carlisle is part of the charm. Harry, being a strong - willed female character, can bring a new perspective to Carlisle's rather stoic and old - fashioned vampire world. And Carlisle, with his centuries - old wisdom, can offer Harry a different kind of stability and guidance compared to what she had in the wizarding world. Also, the exploration of a romantic relationship between a wizard and a vampire is a new and exciting concept that draws readers in.
There's 'Unexpected Mate'. In this fanfiction, fem Harry's unique magic and her personality draw Carlisle to her. It has an interesting plot where they face challenges together, like dealing with the vampire and wizarding worlds' differences. The story also shows how their relationship grows over time.
In fanfiction, it often starts with an instant attraction. Their connection might be based on a shared sense of justice or a mutual understanding of the burdens they carry. For example, fem Harry has the weight of the wizarding world on her shoulders, and Carlisle has his own moral code in the vampire world.
There's a lesser - known one called 'Fem Harry and Caius: A New Beginning'. It starts off with a very unique take on how fem Harry and Caius meet. Their relationship progresses slowly, which is nice as it allows the reader to really understand the connection between them. The story also has some great side characters that enhance the overall plot.
There's also 'Mate Against All Odds'. This one is quite fascinating as it delves deep into the magical bond between Fem Harry and Draco. It shows how they have to fight against the prejudices of the wizarding world to be together. The story is filled with drama, some light - hearted moments, and a really engaging love story between the two characters.
I recall a fanfic titled 'Mate of Hermes: Harry's New Path'. In this one, the fem Harry Potter discovers her connection with Hermes in an unexpected way. The story is filled with twists and turns as they explore their relationship while dealing with the darker forces at play in the wizarding world. It's a long - read but definitely worth it.
One possibility in such a fanfiction could be that their relationship completely alters the dynamics of the original Twilight story. For example, it might change how the Cullen family functions and their interactions with other characters. Maybe Bella's connection with Carlisle would lead to a different approach in dealing with the Volturi.
In this fanfiction, Fem Harry might come from the wizarding world but be a reincarnation of an ancient goddess. Zeus, sensing her divinity, is drawn to her. Their relationship could be filled with power struggles as Harry is used to being independent and Zeus is used to being in control. It would make for an interesting dynamic as they try to understand each other's worlds and powers.
Another aspect could be the exploration of the vampire - human relationship in a different light. With Bella and Carlisle, it's not the typical young vampire - young human love story like Bella and Edward. It might delve deeper into the more mature and complex aspects of a relationship between a much - older vampire and a human.
One popular fanfiction with this concept might be 'A New Bond'. It delves into the unique relationship that forms between Bella's sister and Carlisle. The story is quite interesting as it shows how the two characters from different worlds in the Twilight universe come together. It explores their initial interactions, the shock of the Cullen family, and how they navigate their newfound relationship against the backdrop of the vampire - human world in Forks.
