It gives fans a chance to explore different aspects of the character. For example, in fanfiction, female Trunks can have different relationships, like a closer friendship with Bulma or a rivalry with Gohan. This adds new layers to the existing Dragon Ball Z world.
Female Trunks in fanfiction can also introduce new storylines that might not be possible in the main series. For instance, she could be part of a cross - over with another anime universe. This brings fresh and exciting elements to the Dragon Ball Z fandom, attracting more fans to engage with the character and the overall franchise. It encourages creativity among fans, and they can come up with their own unique takes on her character, which in turn can influence how others in the fandom perceive her.
Fanfiction like this often fills in gaps in the official story. Maybe the official series didn't explore enough of female Trunks' potential. Fan writers can take her character and create scenarios that show her in different lights, whether it's her facing a new enemy or dealing with personal growth. This enriches the overall fandom experience as fans can discuss and share these new ideas. Also, it allows for different interpretations of her character design and abilities, which can inspire fan art and other creative works within the fandom.
