Yamato is also a favorite. His complex relationship with Hitomi and his own skills in the Killing Bites world give a lot of room for fanfiction writers to expand on his character. He can be portrayed in different ways, like his thoughts during battles or his interactions with other characters outside of combat.
Eruza Nakanishi is popular as well. Her unique animal form and her somewhat mysterious personality attract fans. Fanfiction might focus on uncovering more about her past and her true motives in the Killing Bites universe.
One creative idea is to have Naruto characters gain the abilities of the Killing Bites characters. For example, if Naruto could transform like a therianthrope, it would add a whole new dimension to his combat skills. He could use his new form in combination with his shadow clones, creating really unique battle scenarios.
One interesting concept could be exploring the backstories of the characters more in - depth. For example, the past experiences that made the characters develop their unique fighting styles and personalities.
A great Naruto and Killing Bites fanfiction might explore the idea of a crossover tournament. Imagine Naruto characters like Sasuke and Kakashi joining forces with some of the Killing Bites characters to compete in a tournament. This would bring out different strategies and power combinations that would be exciting to read about.
Probably the main characters from the original work tend to be popular in fanfiction. They are well - known and have established personalities that writers can build on.
One common theme is power struggles. Given the nature of the Killing Bites world where different characters have different powers, fanfics often explore who is the strongest and how they gain or lose power.
Obviously Batman and Batgirl are the most important. Batman, as the Dark Knight, brings his skills, experience, and his complex relationship with the Joker to the story. Batgirl, having been through the events of 'The Killing Joke', is central to any exploration of the aftermath.
I think Rachel Morgan is often quite popular. Her strong will and unique powers make her a central figure in many fanfictions.
Megumi Fushiguro is popular as well. His cool and reserved demeanor, along with his powerful cursed technique, attracts a lot of fanfiction authors. They might write about his relationship with other characters, like his unspoken bond with Yuuji, or explore how he further hones his skills in different scenarios.
Peanut is often quite popular. His friendly and goofy nature makes him a favorite among readers. He gets into all sorts of silly situations that are fun to read about.
Pete, Myka, and Artie are the top ones. Pete is popular because of his charm and his ability to find solutions in unexpected ways. Myka is loved for her determination and intelligence. Artie, on the other hand, is interesting because of his long history with the Warehouse. In fanfiction, authors might explore his past relationships with other Warehouse agents or his early days of discovering artifacts. And Claudia, with her youthful energy and her unique role in the Warehouse, is also a popular character to feature in fanfictions.
