Marshall Lee is quite popular too. He's the vampire counterpart to Marceline from the main Adventure Time series. His cool and edgy personality makes for some interesting interactions with Fionna and Cake. Then there's Flame Princess. Her hot - tempered and powerful nature can create great conflict and drama in the fanfiction. And of course, the Lumpy Space Princess can be included for her unique speech pattern and self - centered but lovable personality.
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.
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.
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.
Fionna and Cake are the main characters, of course.
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.
Princess Bubblegum would be a great addition. She could offer her scientific knowledge to help Cake and Jake in their adventures. For example, if they encounter a strange chemical reaction or a mechanical problem, she could come up with a solution. Finn is also a good choice. His bravery and sword - fighting skills would be useful when they face dangerous situations. And Marceline the Vampire Queen could add an element of mystery and her vampire powers might come in handy at times.
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.
Finn, without a doubt. He is the hero of the story, always ready for a new adventure and to help those in need. Jake is also essential as his shape - shifting abilities add a lot of fun and creativity to the stories. Then there's the Ice King. His comical yet somewhat tragic nature makes him a really interesting character to write about. He can be both the villain and, at times, an unlikely ally in fanfiction.
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.
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.
The main characters are Fionna and Cake, of course. Fionna is a really interesting character with her own personality and goals. Cake also has a distinct role and they are often together in their adventures.
