Sometimes characters from different groups or factions within the story are shipped. This adds an element of forbidden love or a Romeo - Juliet type of scenario. For example, in a story about two warring clans, characters from each clan might be shipped together, and fanfiction writers will explore how they can overcome the barriers between their groups to be together.
Darth Vader is often featured. Given their past connection, it creates a very interesting dynamic in the fanfiction. Another character could be Maul. His own complex relationship with the dark side can interact in various ways with Ahsoka's journey into darkness.
Sam and Dean Winchester from 'Supernatural' are often written in such fanfiction. Their dynamic as brothers, with Dean's more brash and Sam's more cerebral nature, lends itself well to humorous situations. Castiel, too, with his often - clueless approach to human customs, is a favorite. In vampire - related fanfiction, characters like Spike from 'Buffy the Vampire Slayer' are commonly used because of his sarcastic and witty personality.
Ruby is often a popular choice. Her innocent and curious nature makes her a likely candidate for such fanfiction. Writers might explore how her naivete could play into ABDL scenarios.
Sans is one of the most commonly written characters. His laid - back yet mysterious nature makes for interesting reactions. Papyrus is also popular as his over - the - top and positive personality gives a lot of room for different reactions. Frisk is often included too, as they are the main character through which a lot of the game's story is told, so their reactions to various in - game events are frequently explored in fanfiction.
Typically, the young protagonists are the most commonly written characters. They are usually in their teens or early twenties, full of energy and idealism. For example, the boy next door type of character, who is kind - hearted and a bit shy, often appears.
Naruto and Sasuke are the most common pair, no doubt. Their story arc in the official Naruto plot has so many layers that can be re - imagined in a slash relationship. But we also see pairings like Gaara and Naruto in some naruto slash fanfiction. Gaara's initially dark nature and Naruto's ability to reach out to him can be an interesting basis for a relationship in these stories.
The main protagonist is often a central character in fanfiction. Since the player character has a lot of agency in the game, it makes sense that they are commonly written about. Also, characters like Ares are quite popular. His role in the game's story and his unique personality make him an interesting subject for fanfic writers. And then there's Scarlett. Her charm and her relationship with other characters are often explored in fanfiction.
Chrom is one of the most commonly written characters. He's a central figure in some of the games, so he has a lot of potential for different storylines. Lucina is also very popular. Her time - traveling aspect gives writers a lot to work with. And then there's Robin. Since they are a customizable character in some versions, there are endless possibilities for fanfiction involving them.
Definitely the veteran fishermen. They have a wealth of experience and stories that fanfiction writers can draw on. People like Phil Harris (although he passed away, his character still has a big impact in fanfiction). His no - nonsense approach and his relationships with the other crew members are often explored. And then there are the greenhorns. Their naivete and their eagerness to prove themselves are things that make them frequently appear in fanfiction.
In Shadowhunters, Clary Fray is often a popular choice. Her journey as a Shadowhunter and her relationships make her an interesting character to write about. In Supernatural, Sam and Dean Winchester are commonly written about. Their brotherly bond and their demon - hunting adventures are rich material for fanfiction writers.
