In some fanfictions, there could be a plot where Fionna discovers a hidden power within herself. This power could be related to her connection with Cake, and it changes the dynamic of their adventures. For example, she might be able to communicate with all animals like Cake does, but in a more powerful way. This could lead to them having to deal with the consequences of this new power, such as other characters being jealous or trying to take advantage of it.
Another plot could involve time travel. Fionna and Cake accidentally travel back in time and end up changing some important events in their world's history. They then have to figure out how to fix the timeline while also dealing with the differences in the past, like different versions of their friends and different rules of magic.
One interesting plot could be Fionna and Cake going on a quest to save their world from a new, mysterious dark force. They might encounter strange new creatures and have to use their wits and friendship to overcome challenges.
A plot could revolve around Cake finding a long - lost relative. This relative could be a powerful and mysterious cat - like being who has some dark secrets. Fionna and Cake then have to decide whether to trust this newfound relative or not. Maybe this relative is being hunted by an even greater evil, and by helping, they put themselves in danger. It could also be a story where Fionna loses her memory and Cake has to take on the role of guiding her through their known world while also trying to find a way to restore her friend's memory.
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.
Well, it's interesting because it gives a fresh perspective on the Adventure Time universe. Fionna and Cake are such unique characters, and the graphic novel delves deeper into their story. It might have new adventures, different relationships explored, and perhaps some new magical elements that are not as prominent in the original series.
Cake is also very popular. Her unique ability to transform and her sassy personality make her a favorite. Many fanfictions explore her relationship with Fionna more deeply, like how she always has Fionna's back in tough situations.
Well, obviously Fionna and Cake themselves are very popular. Fionna is the main protagonist, a fearless adventurer girl, and Cake is her magical and sassy cat - sidekick. Prince Gumball is also a popular character to include. He can add a touch of royalty and his own brand of charm and mystery to the story. Ice King is another one. His zany and often misunderstood nature can bring a lot of humor and chaos to the fanfiction.
Fionna and Cake are the main characters, of course.
Definitely Prince Gumball. His relationship with Fionna can add a lot of drama and interesting storylines. Also, Ice King. He can be both a comical and menacing presence. And of course, Marshall Lee. He has his own unique charm and his interactions with Fionna are always exciting.
Well, they could go on a quest to find a rare ingredient for a special cake that Jake wants to make. Along the way, they encounter various obstacles like a swamp full of gooey monsters or a forest with trees that can move. Also, a plot could be centered around Jake losing his stretching ability and Cake having to find a way to get it back for him. This would involve them visiting different parts of Ooo and asking for help from their friends.
One possible storyline could be Finn exploring the world as Fionna. He might have to deal with the different social dynamics in the female - dominated version of the Adventure Time world. Maybe he'll struggle to fit in at first but then find his own place among the characters like Cake and Prince Gumball.
One interesting plot could be that Naruto somehow ends up in the Adventure Time universe and attracts a harem of the unique characters there. Maybe he uses his ninja skills to protect them from the various threats in Ooo, like the Ice King. And as he spends more time there, different characters start to develop feelings for him.
