If Clary is shown as being manipulative in the fanfic, it would classify her as a bad girl. She could use her charm or wits to get others to do things for her, even if it's not in their best interests. This sort of behavior is often associated with the 'bad girl' archetype in fictional stories.
She could be considered a bad girl if she is overly self - centered in the fanfic. If she always puts her own needs and desires above those of others and doesn't care about the consequences for the people around her, that would give the impression of being a bad girl. Like she might take risks that endanger not only herself but also her friends just to achieve her own goals.
One way is to give her a dark past. For instance, she could have been betrayed by someone she trusted in the past, and this has made her cynical and distrustful of others. As a result, she starts to act out and become a bad girl. So, the writer can explore this backstory and how it affects her present actions.
It could be a side effect of a magic spell or some strange potion she took. In fanfics, all kinds of magical and fictional elements can be introduced, and an improper or misfired spell might disrupt her body's normal functions, including causing diarrhea.
Another reason might be as a form of punishment or lesson. Athena, being the goddess of wisdom, could be teaching Percy something about seeing the world from a different perspective. By turning him into a girl, he might gain new insights into how females are treated in the world of the story, whether it's in the demigod community or among mortals.
Family problems can also play a part. For example, if there's abuse or neglect at home, it can make her lose faith in goodness and turn bad. She may act out in rebellion as a way to cope with the pain.
Peer pressure is a big one. For example, if a good girl is constantly surrounded by people who are doing bad things like drugs or stealing, she might be pressured into joining them.
Well, some writers might do it to show the imperfections of the characters. In the original story, Jace and Clary's relationship seems quite idealized at times. By writing a scenario where Jace cheats, it could be a way to break that ideal and show that they are complex characters with flaws. Also, it could be a way to explore different relationship dynamics and how they could change over time. For example, how would it affect their friendship with other characters? How would they deal with the betrayal? There are many possible storylines that could stem from this one idea.
Well, it could be for the shock value. Writers might want to create something that stands out and grabs the reader's attention immediately. Also, it could be a way to add a touch of realism. In real life, accidents can happen, and by including such a situation in a fanfic, it can make the story seem more relatable in a strange way. Additionally, it might be part of a character - building exercise, showing how a character reacts in a difficult or embarrassing situation.
Another possibility is that she has some sort of stomach ailment in the context of the fanfic. Maybe she ate something bad earlier and now her stomach is protesting. Or perhaps she has a condition that causes her stomach to make noises at unexpected times, which can add an interesting plot twist to the fanfic as other characters might react to it in different ways.
One possible reason could be that the author has run out of ideas for Naruto's character development. Maybe they've explored all the typical arcs and growth opportunities for him in their story, and don't know how to take it further. Another reason might be that they want to shift the focus to other characters in the fanfic. Sometimes, a fanfic starts with one main character like Naruto, but as the story progresses, other characters become more interesting to develop.
One possible reason could be the power of imagination. Fanfic often creates vivid and detailed scenarios that can stimulate a girl's imagination in a sexual way. It might allow her to explore her sexual fantasies in a somewhat safe and private environment.
