What are some interesting adventure time fanfic ideas?

You could create a fanfic where Finn and Jake have to go on a mission to a completely new and unknown land in the Adventure Time world for your FRT fanfic. They might encounter strange new creatures and have to use their wits and powers in ways they haven't before. Maybe they find a land where the rules of magic are different, and they have to adapt quickly.

A great adventure time genderbend fanfic idea could involve Lumpy Space Princess as a male. He could be really vain in a different way, perhaps more focused on his muscles or some other masculine trait. And for Flame Princess, if she were a male, his relationship with Finn would be really different. Instead of the love - hate relationship they had, it could be more of a bromance, with them competing in feats of strength or something similar.

One idea could be that Breezy gets lost in the Land of Ooo and Finn and Jake have to help her find her way back home. Maybe she has a special mission that she needs to complete but can't without their help.

One idea could be a story where Fionna and Cake find a magical portal that leads them to a parallel universe where all the characters have swapped genders. It would be a really fun and unique take on the Adventure Time world. Another idea is that they go on a quest to find the rarest ingredient for a cake that has the power to grant wishes. They could face many challenges along the way, like battling new and strange monsters.

A fanfic could explore the relationship between Ooo and Aaa more deeply. Maybe they get into an argument over how to handle a new threat in Ooo, and through their differences, they learn more about each other and strengthen their friendship.

Another interesting fanfic idea is that Marceline loses her vampiric powers and Marshall Lee has to help her adapt to a more 'human' or at least non - vampiric life. This would lead to a lot of character development as Marceline struggles with her new identity and Marshall Lee learns more about her true self beyond her powers.

One idea could be that the Water Princess discovers a hidden underwater kingdom that was once part of her domain but has been lost. Another could be her facing a drought in the Land of Ooo and having to use her powers in new and creative ways to bring water back. Maybe she has to team up with Finn and Jake to fight an enemy that is polluting the water sources.

Maybe Princess Bubblegum creates a love potion to make Marceline fall in love with her, but things go wrong and it makes all the Candy Kingdom citizens fall in love with each other in a chaotic way. This could lead to a lot of humorous and heart - warming moments as they all try to sort out their new feelings.

One idea could be a story where Hot Dog Princess goes on a quest to find a magical ingredient to make the best hot dogs in all of Ooo. Another could be about her making friends with a new character who doesn't understand the concept of a hot dog princess at first. Maybe a fanfic where she has to defend her hot dog kingdom from an invasion by some sort of food - hating villains.

One plot idea could be Finn and Huntress Wizard going on a quest to find a magical artifact that was lost in the Enchiridion. They face various challenges along the way, like battling strange creatures and solving riddles.
