Finn and Jake are definitely popular choices. Finn's heroism and Jake's laid - back yet powerful nature make them interesting to write about in the academy setting. They can get into all sorts of adventures together and with their friends at the academy.
Finn and Jake are no - brainers. They are the main characters and their family - like bond is so central to the show. Marceline also stands out. Her complex family history makes her a great character for family - themed fanfiction. Additionally, Princess Bubblegum's role as a sort of mother - figure in the Candy Kingdom gives her a family - related aspect that can be delved into. The Flame Princess can also be a popular choice as her relationship with Finn can be seen in the context of a family - like connection.
Seth and Tory are very popular characters to feature. Their complex relationship and their roles as main characters in the original work make them interesting to write about in fanfiction. Writers can explore different scenarios for their relationship, like what if they had met under different circumstances at the academy.
Finn and Jake are often popular. They are the main characters in Adventure Time, so it's natural for them to be the focus in a fanfic that combines with Fallout. Their adventurous nature and unique abilities make for interesting stories in the post - apocalyptic setting.
Naruto is obviously a very popular choice. His journey from a trouble - making student at the academy to a great ninja is well - known, and fanfiction can explore different aspects of his time at the academy, like his relationships with Iruka - sensei or his first attempts at learning new jutsus.
Jack Atlas is often a popular choice. His confident and somewhat arrogant personality makes for great character development in fanfiction. Writers can explore his backstory more deeply and how he interacts with the Duel Academy environment.
Rose Hathaway is definitely a popular choice. She's strong, feisty, and has a complex personality. Her relationship with Dimitri is also a big draw for fans, so featuring her in fanfiction can create a lot of interesting storylines.
Peacock is another favorite. Her zany and unpredictable nature can add a lot of fun to time - based fanfictions. Maybe she accidentally creates a time rift and has to fix it while dealing with different versions of herself from other times.
Finn is a really popular one. He's the hero in Adventure Time, and in high school settings, he can be the brave jock or the new kid who stands up to bullies. Princess Bubblegum is also popular. She can be the smart and popular girl, or the science - nerd type. Jake might be there too, as Finn's sidekick or as a laid - back student.
Finn and Jake are still really popular even in genderbend fanfiction. Their friendship is iconic, and seeing how it changes when their genders are swapped is fascinating to many fans.
Jotaro Kujo is quite popular. His strong and stoic personality makes for interesting interactions in different time periods. Dio Brando is also a common choice. His villainous nature and powerful Stand, The World, can create a lot of chaos when time - travel is involved. And then there's Jonathan Joestar. His noble character can be a great contrast to the more modern and complex characters when he's brought into different timelines through time travel.
