Obviously, the gender - bent Batman is a popular character in these fanfics. Writers often like to explore how this new version of the Dark Knight would interact with the existing Gotham City characters.
Robin is another important character. In a gender - bent scenario, Robin could have a different type of mentorship with a female Batman. Their relationship might be more about mutual growth and learning, rather than the traditional male - dominated dynamic. Also, the way Robin supports the female Batman in combat and detective work could be explored in unique ways.
Harry himself is also a common character for gender - bending. As the main character, changing his gender can completely shift the narrative. It allows for new interpretations of his hero's journey and how he deals with the challenges of the wizarding world as a female. Fans are interested in seeing how a female Harry would handle things like the Triwizard Tournament or facing Voldemort.
Definitely Harry. Since he is the main character, a gender - bent version of him can lead to many different plot twists. Fans are often interested in seeing how a female Harry would interact with the other characters and change the course of the story.
One interesting idea could be seeing Batman as a female and how she might approach crime - fighting differently. For example, she might use more stealth and manipulation in a different way than the male version.
Probably Female Thor. She brings a new and exciting take on the character. Her story can be different from the male Thor's, like how she might handle her relationships with other Asgardians or mortals. Another popular one could be Male Black Widow. People are often interested in seeing how a male version of this complex and deadly assassin would operate. And also Female Iron Man. The idea of a woman in the role of Tony Stark, with her own unique style and approach to technology and heroism, is really appealing.
Natsu is quite popular. Since he's one of the main characters, seeing him as a female brings a whole new dimension to his relationships and his fiery personality. People like to imagine how his interactions with Happy and the rest of the guild would be different.
Definitely Naruto himself (as the gender - bended version). Since the whole concept often revolves around him changing genders, he's at the center of most of these fanfictions. Another popular character would be Sasuke. His relationship with a gender - bended Naruto always makes for an interesting dynamic.
The main characters in 'Ben Ten Gender Bender Fanfic' are likely to start with the gender - bent Ben. Ben's parents might also play a role, perhaps having different reactions to their son/daughter's new gender. The Forever Knights could be part of the story, and their interactions with the gender - bent Ben would be different from the original. Then there are the various aliens that Ben can transform into. How their personalities interact with a gender - bent Ben is something to consider. For example, Heatblast might have a different bond with a female - Ben compared to a male - Ben, and these relationships between the transformed forms and the gender - bent Ben could add a lot of depth to the fanfic.
It has a decent level of popularity. There are many fans who enjoy this genre as it offers a unique take on familiar stories. In some fandoms, it has a significant following, especially those with large and active fan communities.
One popular pairing could be Sakura (as a male) with Naruto. Their friendship already has a strong foundation in the original story, and with Sakura's gender change, it could develop into a romantic relationship. Another might be Sakura (male) and Sasuke. Their rivalry and underlying connection could take on a different form as a same - sex relationship in the gender - bender concept.
One interesting one could be where Batman is a female and she uses her femininity in unique ways to fight crime. For example, she might use her charm to get closer to villains before making a move.
