One possible scenario in this fanfiction could be that Finn's transformation into a vampire brings out a whole new side of his personality. He might struggle with his newfound thirst for blood while still trying to uphold his heroic values. Maybe he teams up with Marceline, who is already a vampire, and she teaches him how to control his urges.
Well, perhaps Finn gets bitten by a vampire while on one of his adventures in the Land of Ooo. As a vampire, he has to adapt to a new lifestyle. He might start to prefer the night and avoid the sun. His diet could completely change, which would be a big shock to his friends who are used to his normal eating habits.
A really cool fanfiction could be set in an alternate universe where Finn was born a vampire. He has to grow up in a world that fears him, but he still has the heart of a hero. He might use his vampire abilities for good, like super speed and strength, to protect those who are weaker, and in the process, he tries to change the perception of vampires in Ooo.
Princess Bubblegum could also be a main character in such fanfictions. She might be the one trying to find a scientific solution to Finn's vampirism. Her intelligence and resources in the Candy Kingdom could play a big role in the story. Another character could be Marceline. As a half - vampire herself, she could either be a mentor to Finn or a source of conflict as she has her own views on vampirism.
In fanfiction about Ice King's daughter in Adventure Time, she often represents a new aspect of the complex Adventure Time universe. Her character can be used to explore themes of family, redemption, and the power of love. For example, some fanfictions might show how she helps Ice King regain his sanity or how she discovers her own identity in a world filled with magic and chaos.
One common plot is her search for her father's true identity. Since the Ice King is a complex character with a troubled past, his daughter might embark on a journey to understand who he was before he became the Ice King. Another plot could be her trying to fit into the Land of Ooo. As a new and somewhat unique character, she has to find her place among the various inhabitants like Finn, Jake, and the princesses.
I recommend the Vampire System of the Foreign Capital. The main character of this book, Xia Lin, was a half-human, half-ghost who possessed both the bloodline of the strongest Demon Capturer of the human race and the bloodline of the Yongye Blood Tribe's Ghost Emperor. Through the System Awakening, he began his journey to the pinnacle of subduing the Loli Wizard, the Royal Swordsman, and the Blood Clan Princess. In this world, he was not only a vampire, but also a powerful zombie king. I hope you like this fairy's recommendation. Muah ~😗
