Katara is often a very popular character in Aang - related fanfiction. Her relationship with Aang in the original series gives a lot of room for exploration in fan - created stories. Writers can expand on their feelings for each other, their shared experiences in fighting the Fire Nation, and how their different bending abilities complement each other.
Toph is also a common and beloved character in such fanfiction. She could be paired with Aang in unique ways. For example, she could teach him earthbending in more creative and unorthodox methods. Or they could go on adventures where Toph's no - nonsense attitude and her powerful earthbending skills help Aang in unexpected situations.
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.
Hinata is very popular. Her shy yet strong - willed nature makes for an interesting dynamic in fanfiction as Naruto's girlfriend. She already has a deep admiration for Naruto in the original series, so it's easy to build on that in fanfiction.
Female Naruto herself is obviously a very popular character in these fanfictions. After all, she is the central figure with the gender - swapped concept. Sasuke also remains popular as his relationship with female Naruto can be explored in new and exciting ways. Their dynamic can be more complex and filled with different emotions compared to the original story.
Sokka could be one of the main characters. He might be the one helping Aang with his schoolwork, especially in subjects like history or math, using his own knowledge and quick thinking.
Sokka would also be a common character. His strategic mind could be very useful in a different time period. He might be the one who figures out how to deal with the new situations they encounter while in the past. For instance, if they need to outwit an enemy in a historical battle, Sokka would be the one to come up with a plan.
Well, Naruto himself is extremely popular in relation to them. He has connections to Kushina as her son, and his interactions with Kurenai also add to his popularity in these scenarios.
Sakura is often very popular. In many fanfictions, she is given more complex storylines. For example, some might explore her growth as a medical ninja further. Hinata is also a favorite. Her shy but strong - willed nature is often elaborated on, like in fanfictions where she has to step up and lead in Naruto's absence. Then there's Tsunade, a powerful female figure. Fanfictions may focus on her past and how she overcame various challenges to become the Hokage.
Sakura is a top pick. In the Naruto world, she has a complex character arc. In female henge fanfiction, she can use her intelligence and new - found male form (through henge) to outwit enemies or gain access to places only males can go. Another popular one is Ino. She's very confident, and seeing her transform into a male could be used to explore different aspects of her personality, like how she would handle male - specific situations in the ninja world. And Temari also has potential. Her tough - as - nails attitude could be interesting when transferred to a male form via henge.
It really depends on the specific fandom. But often, strong - willed and intelligent female characters from the original work become very popular in such fanfictions. For instance, if it's a superhero - based fanfiction, a female superhero like Wonder Woman could be a popular character to explore in a world where females rule. She already has the strength and leadership qualities, and in this new context, her character can be developed further in terms of ruling and decision - making.
I think Rachel Morgan is often quite popular. Her strong will and unique powers make her a central figure in many fanfictions.
